Item 1. Business

Overview

We are a globallyglobal commercial-stage biotechnology company focused clinical-stage biopharmaceutical company dedicated to becomingon developing and commercializing innovative molecularly-targeted and immuno-oncology cancer therapeutics. We started as a leader in the discoveryresearch and development of innovative, molecularly targeted and immuno-oncology drugs forcompany in Beijing in 2010. Over the treatment of cancer. We believe the next generation of cancer treatment will utilize therapeutics both as monotherapies and in combination to attack multiple underlying mechanisms of cancer cell growth and survival. We further believe that discovery of next-generation cancer therapies requires new research tools. To that end,last ten years, we have developed into a proprietary cancer biology platform that addresses the importance of tumor-immune system interactionsfully-integrated global biotechnology company, with significant commercial, manufacturing, and the value of primary biopsies in developing new models to support our drug discovery effort.

        Our strategy is to develop a pipeline of drug candidates with the potential to be best-in-class monotherapiesresearch and also important components of multiple-agent combination regimens. Over the last six years, using our cancer biology platform, wedevelopment capabilities.

We have developed clinical-stage drug candidates that inhibit the important oncology targets Bruton's tyrosine kinase, or BTK, RAF dimer protein complex and PARP family of proteins, and an immuno-oncology agent that inhibits the immune checkpoint protein receptor PD-1. For each of our molecularly targeted drug candidates, we have achieved proof-of-concept by observing objective responses in defined patient populations. Our BTK inhibitor is currently in pivotal studies in North America, Europe, Australia, New Zealand, and China. Our PD-1, PARP and RAF dimer inhibitors are currentlybuilt substantial commercial capabilities in the dose-expansion phasesPeople's Republic of their respective clinical trials. As of March 20, 2017, trials of our four clinical-stage drug candidates, as monotherapiesChina ("PRC" or "China") and in combination, have enrolled a total of over 980 patients. We have Investigational New Drug, or IND, Applications in effect for our BTK, PD-1 and PARP inhibitors with the U.S. Food and Drug Administration, or FDA. All four of our drug candidates are in the clinic in China, including our BTK drug candidate being in two pivotal studies. We believe that each of our clinical-stage drug candidates is the first in their respective classes being developed in China under the Category 1.1 domestic regulatory pathway to enter into human testing and to present clinical data.

        Our research operations are in China, which we believe confers several advantages including access to a deep scientific talent pool and proximity to extensive preclinical study and clinical trial resources through collaborations with leading cancer hospitals in China. Beyond the substantial market opportunities we expect to have globally, we believe our location in China provides us the opportunity to bring best-in-class and/or first-in-class monotherapies and combination therapeutics to our home market where many global standard-of-care therapies are not currently approved or available. We have assembled a team of 348 individuals in China, the United States, and Australiaare currently marketing two internally-developed drugs and three in-licensed drugs. We also anticipate introducing five more in-licensed drugs into the China market in the next one to two years. In the United States, we market BRUKINSA (zanubrutinib) for adult patients with mantle cell lymphoma ("MCL") who have received at least one prior therapy and in China, we have received marketing approval and are in the process of launching tislelizumab for patients with classical Hodgkin’s Lymphoma ("cHL") who have received at least two prior therapies. We have filed four additional supplementary new drug applications ("sNDA") for regulatory approvals in China and are planning for launches in these additional indications in 2020. Our in-licensed portfolio includes ABRAXANE®, REVLIMID® and VIDAZA®, which we have been marketing in China since 2017 under a license from Celgene Logistics Sàrl, a Bristol-Myers Squibb company ("BMS"). We plan on launching additional in-licensed products in China from our collaborations, including XGEVA® (denosumab), KYPROLIS® (carfilzomib) and BLINCYTO® (blinatumomab) from Amgen Inc. ("Amgen"), and SYLVANT® (siltuximab) and QARZIBA®(dinutuximab beta), from EUSA Pharma ("EUSA").

We have built deep scientific talentclinical development capabilities, including a more than 1,100-person global clinical development team that is running over 60 ongoing or planned clinical trials that have enrolled over 7,500 patients and extensivehealthy subjects. We are conducting late-stage clinical trials of BRUKINSA and tislelizumab, including 26 registration or registration-enabling trials in 15 discrete cancer indications. Our internal research capabilities have yielded another late-stage asset, pamiparib, and five other internally-developed drug candidates are currently in early-stage clinical development. In addition, we have been able to leverage our capabilities and China’s rising importance as a clinical science center to expand our clinical and pre-clinical portfolio with in-licensed drug candidates. We are also working with high-quality contract manufacturing organizations ("CMOs") to manufacture our internally-developed commercial and clinical products in China and globally and have built state-of-the-art small molecule and biologic manufacturing facilities in China to support the launches and potential future demand of our internally-developed products.
Based on the strength of our China-inclusive global development and commercial capabilities, we have entered into collaborations with leading pharmaceutical experience who are deeply committedand biotechnology companies to advancing ourdevelop and commercialize innovative medicines in China and the Asia-Pacific region. In October 2019, we entered into a strategic collaboration with Amgen pursuant to which we have agreed to collaborate on the commercialization of Amgen’s oncology products XGEVA, KYPROLIS, and BLINCYTO in China, and the global development and future commercialization in China of up to 20 of Amgen's clinical- and late pre-clinical-stage pipeline products, including AMG 510, Amgen’s first-in-class investigational KRAS G12C inhibitor.
Our Strategy
Our mission is to become a global leader in next-generation cancer therapies.

the discovery, development, and commercialization of innovative medicines for the treatment of cancer. Key elements of our strategy are as follows:

Realize Two Large Commercial Opportunities with BRUKINSA (zanubrutinib) and tislelizumab. Zanubrutinib is a wholly-owned, potentially best-in-class small molecule inhibitor of Bruton’s tyrosine kinase ("BTK") for B-cell malignancies. We believe zanubrutinib may have efficacy and safety advantages compared to the other approved BTK therapies based on its ability to achieve full BTK occupancy and minimize off-target binding. There is a large global commercial opportunity for BTK inhibitors, with global revenues totaling approximately $5.8 billion in 2019 according to published reports. We believe that our clinical experience to date in over 2,500 patients, along with our broad clinical development plan, position us to capitalize on this commercial opportunity. In November 2019, we received accelerated approval for BRUKINSA from the U.S. Food and Drug Administration ("FDA") for the treatment of adult patients with MCL who have received at least one prior therapy. We have built a commercial team in the United States and launched BRUKINSA in late 2019. In addition, we have submitted two new drug applications ("NDAs") in China for zanubrutinib for the treatment of patients with relapsed or refractory ("R/R") MCL and patients

with R/R chronic lymphocytic leukemia ("CLL") or small lymphocytic lymphoma ("SLL"). Both applications are being reviewed under priority review status. We believe that oncology treatment has entered an era of revolutionary change in which cancer drugs will be usedare conducting a broad clinical program for zanubrutinib, with near-term data readouts expected, both as a monotherapy and in combination with other therapies.
Our most recently approved drug is tislelizumab, a wholly-owned antibody against the immune checkpoint receptor programmed cell death protein 1 ("PD-1") that was designed to attack multiple underlying mechanismsminimize Fc-gamma receptor binding, which is believed to play an essential role in activating phagocytosis in macrophages, to minimize its negative impact on T effector cells. We received approval from China’s National Medical Products Administration ("NMPA") in December 2019 to market tislelizumab for the treatment of cancer cell growth and survival. Due to breakthroughs in gene sequencing and methods of tumor characterization, cancer is rapidly being redefined from a paradigm of classification based on tissue of origin to molecular characteristics. As a result, this ability to better classify cancers has enabled the development of molecularly targeted drugs that address specific cancer subpopulations and provide high response rates in tumorspatients with particular mutations.cHL who have received at least two prior therapies. In addition, we have filed an sNDA in China for tislelizumab in patients with previously treated locally advanced or metastatic urothelial carcinoma ("UC") which has been granted priority review by the development of immuno-oncology agents such as antibodies targetingCenter for Drug Evaluation ("CDE") at the CTLA-4NMPA and PD-1 protein receptors and the PD-L1 protein has demonstrated the importance of the human immune system in cancer therapy and the potential for


more durable responses from agents that activate the immune system to identify and eliminate tumors.is currently under review. We believe that the future of cancer therapy will involve combinations of molecularly targeted and immuno-oncology drugs tailored to particular tumor sub-groups and have directed our research efforts at both types of drugs.

        Our belief that this fundamental shift was about to occur in cancer research led us early in our history to develop a cancer biology platform that addresses the importance of tumor-immune system interactions and the value of primary tumor biopsies in developing new models. Our proximity to leading cancer treatment centers in Beijing and our close relationships with clinicians who treat patients and perform biopsies and surgeries at those centers have allowed us to develop an extensive collection ofin vivo,ex vivo andin vitro cancer models. Given our belief that the human immune system can play an important role in combating cancer and that future treatments will involve combination therapies, we have introduced elements of a functional immune system into these models. Our proprietary models allow our research team to better select targets and to screen and evaluate therapeutic agents that we believe have significant potential alone or in combination for treating a variety of cancers. Our models are a key component in the screening cascade we follow in our drug discovery effort and permit us to evaluate potential drug candidates in conditions that much better approximate a patient's cancer at the time of treatment. This is particularly significant when drug discovery requires evaluation not only of monotherapies but also multiple combinations and regimens targeting specific mutations while simultaneously immobilizing the defenses cancer cells mount against the human immune system.

        Since our inception in 2010, we have raised approximately $170 million in private equity financing and $10 million in non-convertible debt financings. On February 8, 2016 and November 23, 2016, we completed our initial and follow-on public offerings, and received net proceeds of $166 million and $199 million, respectively, after deducting underwriting discounts and offering expenses.

Next Generation of Cancer Treatment

        We believe that oncology treatment is rapidly evolving, offering patients the promise of more frequent and more durable responses that improve survival from months to years while avoiding the severe toxicities typically associated with chemotherapy. While these outcomes may occasionally be achieved with monotherapy, we believe that the emergence of resistancethere is a major problemlarge and that better outcomes will be achievable by combining multiple drugs as it is done in treating infectious diseases.

        The next generation ofgrowing opportunity for novel cancer therapies will be based, we believe, on advances in four areas:

    Reclassification of disease based on underlying molecular defect.  Due to breakthroughs in gene sequencing and methods of tumor characterization, cancer is increasingly being redefined from a paradigm of tumor classification based on originating tissue type, such as lung, colorectal or ovarian, to one of characterization based on the genetic aberrations and signature gene expression patterns, such as in HER2, BRCA, BRAF, ALK and EGFR. As a result, many more disease subpopulations can be specifically targeted, resulting in more effective treatment than was possible in the past. Disease classifications are substantially more sophisticated than 10 years ago, and we believe they will become increasingly so in the future.

    Effective molecularly targeted therapy, but often limited durability.  The ability to better understand the mechanisms underlying cancer has allowed the development of effective drugs that target important molecular drivers and generate high response rates in tumors with these drivers. Examples of approved drugs include gefitinib and erlotinib for patients with EGFR mutations, crizotinib and ceritinib for patients with ALK translocations, and vemurafenib and dabrafenib for patients with BRAF mutations. Unfortunately, in many of these cases, responses have been relatively short-lived as cancers can develop alternative mechanisms to compensate and ultimately bypass these drugs' blockade of molecular signaling. For example, while 52% of

      previously treated metastatic melanoma patients with BRAF V600E achieved an objective response once treated with vemurafenib, the median duration of response was only 6.5 months.

    Immune checkpoint inhibitors have shown remarkable clinical benefit, demonstrating the power of the immuno-oncology approach.  Improved understanding of cancer immunology has led to the identification of critical immune checkpoints—i.e., mechanisms by which cancer cells evade the surveillance of the immune system. Inhibitors of the immune checkpoints CTLA-4 and PD-1 have shown success in the clinic. Two PD-1 monoclonal antibodies, nivolumab and pembrolizumab, and one PD-L1 monoclonal antibody, atezolizumab, have been approved by the FDA. To date, the FDA has approved immune checkpoint inhibitors as monotherapy in a number of cancers, including melanoma, non-small cell lung cancer, or NSCLC, kidney cancer, Hodgkin's lymphoma, bladder cancer, and head and neck squamous cell carcinoma, or HNSCC. Microsatellite instability-high, or MSI-h cancers and Merkel cell carcinoma are also under FDA review for approval. In addition to these indications, immune checkpoint inhibitors are being studied as monotherapy in clinical trials in a wide spectrum of cancers. Some of these trials have advanced to the pivotal stage, such as gastric cancer, glioblastoma, liver cancer, esophageal cancer, small cell lung cancer, or SCLC, triple negative breast cancer, or TNBC, and cutaneous squamous cell carcinoma. Among these indications, immune checkpoint inhibitors have demonstrated superior overall survival in melanoma, NSCLC, kidney cancer, bladder cancer, HNSCC, and gastric cancer in large randomized controlled clinical trials. Although certain distinct toxicities associated with PD-1 and PD-L1 antibodies have been observed, these agents have been generally well-tolerated.

    The need for and early promise of combination therapy.  While clinical data with molecularly targeted drugs as monotherapy have been encouraging, achieving a high rate of durable responses remains difficult in most cancer types. In addition, objective responses to checkpoint inhibitor monotherapies including PD-1, PD-L1 and CTLA-4 antibodies have been achieved in still small portions of unselected, solid tumor patients. Although the biological mechanisms underlying combinations are being explored in the field, recent third-party clinical studies have demonstrated the potential of combination therapy to achieve high tumor response rates, as are often seen with targeted therapy, but with greater durability, as is seen with immuno-therapy agents. The combination of targeted and immuno-therapies may generate durable responses with much better survival rates.

        We believe that the industry-standard for cancer biology models has not evolved along with current oncology research and drug discovery and thus is an insufficient framework from which to develop the next generation of oncology drugs we envision. In response, we have built a comprehensive cancer biology platform specifically to address a new generation of cancer treatments.

Next-Generation Cancer Biology Platform

        Fundamental changes in cancer research led us early in our history to develop a cancer biology platform that incorporates improved models and processes better suited to drug discovery in the new world of immuno-oncology combinations and addresses the importance of tumor-immune system interactions and the value of primary biopsies. Conventional models for oncology drug discovery have used cultured cell lines that are often decades old and have characteristics that are not representative of the tumors in actual cancer patients. In addition, tumors from these cell lines have been transplanted in immune-compromised hosts in commonly-used xenograft tumor models. Therefore, animal models utilizing these cell lines have limited predictive value for new therapies. While animal models derived from surgical samples, such as patient-derived xenograft models, or PDX models, are an improvement over the old cell lines, a surgical sample is unlikely to represent the state of the cancer at the time of intended treatment. Because conventional models, including PDX models, require the use of immune-deficient animals, they cannot mimic interactions between the tumor and the host immune system.


        The cancer biology platform we developed enables us to test a large panel of tumor models for sensitivity to the drug candidates we generated, identify drug-resistance mechanisms in many cancers, explore combination strategies and regimens, and improve our understanding of the contributions of tumor micro- and macro-environments in cancer treatments.

        Scientific Approach.    Our platform brings together the following:

    Access to a broad array of primary patient biopsies and tissue samples, enabled by our proximity to and partnerships with leading China-based oncology centers, allows us to build novelin vivo,ex vivo andin vitro models that we believe more accurately represent patients' cancer disease states at the time of treatment.

    Methods for better approximating the interactions between a tumor and a patient's immune system, including:

    Introduction of elements of the human immune system into ourin vivo,ex vivo andin vitro models;

    Creation of a variety of novel assays to investigate the effects of drug combinations and study their impacts on the human immune system and the tumor microenvironment; and

    An effective screening cascade for oncology drug development that incorporates all of these elements.

        Sustainable Leadership Position.    We believe that our early recognition of the importance of tumor-immune system interactions and the value of primary biopsies in developing new models for future cancer research has allowed us to develop a proprietary cancer biology platform that provides significant competitive advantages in developing the next generation of cancer therapeutics.

        We believe that several of these advantages are sustainable:

    Our close relationships with clinicians and our proximity to major oncology centers in China provide us convenient and difficult-to-replicate access to primary tissue samples that greatly enhance the effectiveness of our oncology models.

    Our time and effort in developing and validating new models and processes, through the commitment and focus of our large scientific team, has allowed us to advance our capabilities meaningfully ahead of many current cancer drug development approaches. Over the last six years, our team of over 80 biologists has been focused on the continued development of our cancer biology platform.

    Our non-hierarchical structure and highly cooperative organizational culture allows us to access the cross-functional capabilities needed to develop, maintain and continually improve our new generation cancer biology platform.

        Our robust preclinical and clinical pipeline demonstrates our significant commitment and ability to devote the necessary time, energy and resources required to build, validate and continue to advance our cancer biology platform. Our platform has enabled us to advance four candidates to the clinic and to execute our combination strategy. We believe we are one of only two companies today to wholly own both a clinical-stage BTK inhibitor for cancer treatment and PD-1 inhibitor and one of the few companies to have discovered, and advanced to the clinical stage, a PARP inhibitor and PD-1 inhibitor or a BRAF inhibitor and PD-1 inhibitor for use as combination therapies. We believe that our cancer biology platform is critical to developing rational combinations that enable us to become a leader in next-generation cancer therapies.


Our Clinical-Stage Drug Candidates

        We have used our cancer biology platform to develop four clinical-stage drug candidates that we believe have the potential to be best-in-class or first-in-class. In addition, we believe that each has the potential to be an important component of a drug combination addressing major unmet medical needs.

        Moreover, we believe that compounds in our clinical and preclinical pipeline have the potential to be first-in-class therapeutics in China and the market opportunity for PD-1/PD-L1 antibody therapies may be especially attractive, as locally developed compounds,this class of agents has demonstrated anti-tumor activity in all four of the most common tumors in China: lung cancer, gastric cancer ("GC"), liver cancer and esophageal cancer ("EC"). According to qualify forpublished reports, China has a separate,higher proportion of PD-1 responsive tumors in its total annual cancer incidence in comparison to other geographies like the U.S. and Europe. According to a published study (Chen et al., Cancer Statistics in China, 2015, CA: Cancer J. Clin. 2016; 66(2):115-32), which we refer to as Chen et al. 2016, the annual incidence of the top ten PD-1 responsive tumors in China is estimated to be 3.0 million out of 4.3 million in total annual cancer incidence. We believe that we are uniquely positioned to capture this opportunity with our strong presence and experience in China, our global clinical development capabilities, the breadth of our development plan, which has enrolled more than 5,000 patients to date, including 15 registration or potentially accelerated, regulatory path.

        Over time, we intend to strengthen our position with additional drug combinations utilizing our own drugsregistration-enabling trials, and in some cases third-party drugs to compete globally as first-in-combination and best-in-combination cancer therapies.

Utilize Our Key Strategic Clinical and Commercial Capabilities. We believe that recent changes in the regulatory environment in China have led to an unprecedented opportunity in our industry. Historically, the regulatory environment in China was considered highly challenging, with clinical development delays and regulatory approvals taking much longer than in the United States and the EU. To address these challenges, the NMPA issued a series of reform policies and opinions, which, among other things, has expanded access to clinical patients and created an opportunity to expedite drug development and approval by removing delays and creating an environment with international quality standards for drug development, manufacturing and commercialization in China. These regulatory reforms allow clinical trials in China to play a major role in global drug development programs, with the data generated in China used to support approvals outside of China. However, challenges to benefit from these reforms remain, including limited contract research organization ("CRO") capability, a limited talent pool and clinical data and trial management challenges. Our strategy has been to aggressively build our clinical development and commercial capabilities in China to take advantage of these changes and mitigate the challenges with accessing China as a clinical science center. Our global oncology development team is made up of more than 1,100 employees, approximately 60% of whom are in China. We are dedicated to performing studies that conform to the highest global International Council for Harmonisation ("ICH") standards. We have initiated 12 global, China-inclusive pivotal studies and 26 pivotal or potentially registration-enabling studies. We have over 60 ongoing or planned trials and have enrolled over 7,500 patients and healthy subjects in our clinical trials. From a commercial perspective, our strategy in China is to seek broader access to patients in need of innovative medicines through national reimbursement. This strategy requires a large commercial organization. We have increased our commercial capability from just over 150 people when we acquired the commercial operations of Celgene (now part of BMS) in China in 2017 to over 900 people as of the end of 2019. We believe that we are well-positioned to launch our current and future pipeline of internally-developed and in-licensed drugs in China and take advantage of the opportunity of improved national reimbursement.
Expand Our Portfolio by Leveraging Our Clinical and Commercial Capabilities. As many leading pharmaceutical and biotechnology companies evaluate opportunities in China, we believe that collaborating with us could allow these companies to efficiently and effectively access deep local clinical development, commercial and manufacturing capabilities at global quality standards. For example, we have leveraged our unique China-inclusive development and commercial capabilities to expand our portfolio through our collaboration with Amgen. In addition, we have entered into over 10 transactions since 2017 in which we have added innovative pre-clinical, clinical and/or commercial-stage drugs and drug candidates to our portfolio. Our strategy is to continue to aggressively evaluate licensing opportunities to add to our pipeline of drugs and drug candidates.
Pursue a New Model for Global Growth. We believe that the large addressable patient population and the expansion of reimbursement of innovative medicines in China can support a new business model for growth in our industry by allowing R&D investment for these drugs to be leveraged over a significantly larger patient pool, which can enable broader access worldwide with more affordable pricing as compared to the traditional priority market model. This

global access and pricing model will allow us to leverage our strong clinical and commercial capabilities in China and globally. It also provides an opportunity to obtain return on the investments made to develop our portfolio of drug candidates. We evaluate worldwide markets by researching the opportunities, start-up risks and costs, and our capabilities. Subsequently, we design targeted market entrance strategies and plan to pursue these global markets in a staged manner based on investment and return analyses. We plan to seek approvals of our portfolio compounds globally in order for us to capitalize on these opportunities.

We commercialize the following wholly-owned cancer medicines, for which we have worldwide commercial rights:
BRUKINSA
BRUKINSA is a second-generation small molecule BTK inhibitor designed to maximize BTK occupancy and minimize off-target binding effects. On November 14, 2019, BRUKINSA received accelerated approval from the FDA as a treatment for MCL in adult patients who have received at least one prior therapy. BRUKINSA is the first BeiGene-discovered product to be approved. Currently, we have a 100-plus person commercial team marketing BRUKINSA in the United States. In China, we have filed NDAs for the treatment of patients with R/R MCL and patients with R/R CLL/SLL, and those applications are pending under priority review.

Market Opportunity and Competition
Lymphomas are blood-borne cancers involving lymphatic cells of the immune system. They can be broadly categorized into non-Hodgkin’s lymphoma ("NHL") and Hodgkin’s lymphoma ("HL"). Depending on the origin of the cancer cells, lymphomas can also be characterized as B-cell or T-cell lymphomas. B-cell lymphomas make up approximately 85% of NHLs and comprise a variety of specific diseases involving B-cells at differing stages of maturation or differentiation. According to statistics from the Surveillance, Epidemiology and End Results ("SEER") program of the U.S. National Cancer Institute, there were 74,200 new NHL cases and 19,970 deaths, and of these NHL cases the incidence of CLL was 20,720 and there were 3,930 deaths from CLL in 2019 in the United States. Similar SEER analyses calculated U.S. incidence rates of 3,000 for MCL and 1,350 for Waldenström’s macroglobulinemia ("WM"). According to Chen et al. 2016, and GLOBOCAN’s online Global Cancer Observatory analyses on cancer statistics in China, there are an estimated 88,200 to 93,097 new lymphoma cases and 52,100 to 50,865 deaths in China each year, and of the lymphoma cases, approximately 90% are NHL and approximately 4.5% of the NHL cases are CLL/SLL.
Conventional methods of treating lymphomas vary according to the specific disease or histology, but generally include chemotherapy, antibodies directed at CD20, a molecular marker found on the surface of B-cells, and, less frequently, radiation. Recently, significant progress has been made in the development of new therapies for lymphomas, including BTK inhibitors, the phosphoinositide 3-kinase ("PI3K") inhibitors, idelalisib, copanlisib and duvelisib, and the Bcl-2 inhibitor, venetoclax. Recently, cell-based therapies have been receiving approvals. These include YESCARTA® (axicabtagene ciloleucel) and KYMRIAH™ (tisagenlecleucel), both anti-CD19 therapies.
The BTK inhibitor IMBRUVICA® (ibrutinib) was first approved by the FDA in 2013 for the treatment of patients with MCL who have received at least one prior therapy. Since that time, ibrutinib has received supplemental FDA approvals for the treatment of patients with CLL/SLL, CLL/SLL patients with 17p deletion, patients with WM, patients with marginal zone lymphoma ("MZL") who have received at least one prior anti-CD20-based therapy, patients with chronic graft versus host disease after failure of one or more lines of systemic therapy, in combination with rituximab in WM, and in combination with obinutuzumab in CLL/SLL. Ibrutinib is also approved by the European Medicines Agency ("EMA") for the treatment of patients with MCL, CLL and WM. Ibrutinib has been approved in over 90 countries and regions, and it was approved and launched in China at the end of 2017 for the treatment of patients with R/R CLL/SLL and R/R MCL. Subsequently, in July 2018, ibrutinib was also approved for first-line CLL/SLL. Another BTK inhibitor, CALQUENCE® (acalabrutinib) was approved by the FDA in 2017 under accelerated approval for the treatment of patients with MCL who have received at least one prior therapy, and in November 2019 for use in adults with CLL/SLL. In 2019, global revenues for BTK inhibitors were approximately $5.8 billion according to published reports.
Tislelizumab
Tislelizumab is a humanized IgG4 monoclonal antibody against the immune checkpoint receptor programmed cell death protein 1 (" PD-1"), that we specifically designed to minimize binding to Fc receptor gamma ("FcγR"), which is believed to play an essential role in activating phagocytosis in macrophages, to minimize its negative impact on T effector cells. Tislelizumab is currently being evaluated in a broad pivotal clinical pipelineprogram for both solid tumor and hematological indications, both globally and in China:

China. We submitted an NDA for approval in China in 2018 for the treatment of R/R cHL, which received priority review and was approved on December 26, 2019. We are planning to launch tislelizumab in China in the first quarter of 2020. We have also filed a sNDA in China for the treatment of urothelial bladder cancer ("UBC") in May 2019 and expect NMPA approval in 2020, and we expect to submit a sNDA in first line squamous non-small cell lung cancer ("NSCLC") in 2020 based on the positive interim analysis of our Phase 3 study announced in January 2020. Additionally, we plan to discuss with regulators our Phase 2 study in second- or third-line hepatocellular carcinoma ("HCC") in 2020, and we expect readouts from several studies of tislelizumab in 2020. We have full commercial rights to tislelizumab, following the termination of our collaboration agreement with Celgene prior to its acquisition by BMS.

Market Opportunity and Competition
A number of PD-1 or PD-L1 antibody drugs have been approved by the FDA. These include Merck’s KEYTRUDA® (pembrolizumab), BMS’s OPDIVO® (nivolumab), Roche’s TECENTRIQ® (atezolizumab), AstraZeneca’s IMFINZI® (durvalumab), Pfizer and Merck Sereno’s BAVENCIO® (avelumab), and Regeneron and Sanofi’s LIBTAYO® (cemiplimab). In the global setting, several PD-1 or PD-L1 antibody agents are in clinical development in addition to tislelizumab, such as Novartis’ PDR-001, GlaxoSmithKline/Tesaro’s TSR042, Pfizer’s PF-06801591, and AstraZeneca’s MEDI0680. In China, as of February 14, 2020, there are five other approved PD-1 antibodies, OPDIVO® (nivolumab) and KEYTRUDA® (pembrolizumab), as well as Junshi’s TUOYI (toripalimab), Innovent’s TYVYT (sintilimab), and Hengrui’s AIRUIKA® (camrelizumab), and there are two approved PD-L1 antibody agents AstraZeneca's IMFINZI® (durvalumab) and Roche's

TECENTRIQ® (atezolizomab). There are approximately 40 more PD-1 and PD-L1 agents in late-stage development in China, of which one has filed for approval as of the end of January 2020.
Globally, the top four PD-1/PD-L1 antibody drugs had sales of approximately $21 billion in 2019 based on public reports. We believe that there is a large commercial opportunity in China for PD-1 and PD-L1 antibody drugs. Currently available clinical data suggest that some of the most prevalent cancers in China, such as lung, gastric, liver and esophageal cancer, are responsive to this class of agents. According to the World Health Organization's GLOBOCAN online database, in 2018 China suffered 39%, 50%, 47%, and 56% of all deaths from lung, gastric, liver, and esophageal cancers, respectively, in the world. Collectively, these four tumor types comprised over 2.3 million new cases in 2016 in China alone, according to Chen et al. 2016. In addition, China has a higher proportion of PD-1 responsive tumors in its total annual cancer incidence in comparison to other geographies like the U.S. or Europe. According to Chen et al. 2016, the annual incidence of the top 10 PD-1 responsive tumors in China is estimated to be 3.0 million out of 4.3 million in total annual cancer incidence. In comparison, the estimated annual incidence of the top 10 PD-1 responsive tumors is 0.9 million out of 1.7 million in total annual cancer incidence in the United States, and 0.9 million out of the 1.8 million total in the EU5 countries (United Kingdom, France, Germany, Spain and Italy) according to the SEER program of the U.S. National Cancer Institute and the World Health Organization.
We commercialize the following cancer drugs in China under an exclusive license from BMS:
ABRAXANE
ABRAXANE (paclitaxel albumin-bound particles for injectable suspension) is a solvent-free chemotherapy product which was developed using BMS’s proprietary nanoparticle albumin-bound (nab®) technology platform. This protein-bound chemotherapy agent combines paclitaxel with albumin. Globally, ABRAXANE is approved for uses in breast cancer, NSCLC, pancreatic cancer, and GC, with geographic differences in labeling. In China, ABRAXANE is approved for metastatic breast cancer after failure of combination chemotherapy for metastatic disease or relapse within six months of adjuvant chemotherapy. Prior therapy should have included an anthracycline unless clinically contraindicated.
According to Chen et al. 2016, there were approximately 4.3 million new cancer cases and 2.8 million cancer deaths in China in 2015, with breast cancer as the most common tumor type in Chinese women. It is estimated that in 2015 breast cancer affected 268,600 women and resulted in 69,500 deaths. Targeted therapy, hormone therapy and chemotherapy are three main strategies to treat different types of breast cancer.
Taxanes are the backbone chemotherapy to treat triple negative breast cancer, Her2+ or aggressive estrogen-receptor-positive and/or progesterone-receptor-positive breast cancer patients. ABRAXANE is the only currently approved taxane that does not need pre-medication with dexamethasone to prevent hypersensitivity reactions, and several Phase 3 trials have demonstrated its efficacy and safety based on comparison to solvent-based taxanes in both metastatic and neo-adjuvant breast cancer settings. Unlike other taxanes, ABRAXANE has demonstrated unique and strong efficacy in pancreatic cancer and has become the backbone of first line standard of care for metastatic pancreatic cancer globally.
The taxanes marketed in China include two branded solvent-based paclitaxel (TAXOL® and ANZATAX) formulations, one branded docetaxel (TAXOTERE®) formulation, one paclitaxel liposome (LIPUSU®), one albumin-bound paclitaxel (ABRAXANE) and generic forms of solvent-based taxanes and ABRAXANE, including albumin-bound paclitaxel products from CSPC Pharmaceutical Group , Hengrui and Qilu. LIPUSU is currently the market leader with approximately one-third of the market share.
ABRAXANE is listed on provincial reimbursement drug lists of Hubei, Ningxia, Jiangsu, and Hunan, as well as in critical illness insurance program in Zhejiang and Shandong. In January 2020, we were notified by the National Healthcare Security Administration of China that our tender offer for ABRAXANE was one of the winning tenders in China’s centralized procurement process, with a reduction from the current pricing, which is expected to take effect in the second quarter of 2020.
On May 30, 2019 we announced that the NMPA accepted the supplemental import drug application for ABRAXANE in combination with gemcitabine, as a first-line treatment of patients with metastatic adenocarcinoma of the pancreas ("mPC").
REVLIMID
REVLIMID (lenalidomide) is an oral immunomodulatory drug that was approved in China in 2013 for the treatment of multiple myeloma ("MM") in combination with dexamethasone in adult patients who have received at least one prior therapy. In February 2018, REVLIMID received NMPA approval of a new indication for the treatment of MM in combination with dexamethasone in adult patients with previously untreated MM who are not eligible for transplant.
Globally, the incidence of MM is estimated at two to three per 100,000, with a male-to-female ratio of 1.6:1, and most patients are over 40 years old, according to Siegel et al., 2011 and IMS analysis. It is estimated that the incidence rate of MM is

approximately one to two per 100,000 people in China, or approximately 21,000 new patients in 2019, out of which 10,000 are in urban populations, according to Lu et al., 2014, IMS analysis, and local market research. With a growing aging population and improving diagnosis, China has seen a steady increase in MM incidence.
Although MM cannot be cured, the progression of the disease can be controlled. The purpose of treatment is to extend patients’ survival and improve quality of life. The main treatments for MM in China include VELCADE®, which is a proteasome inhibitor marketed by Johnson & Johnson in China since 2006, REVLIMID, NINLARO® (ixazomib), an oral proteasome inhibitor developed by Takeda, and generic forms of VELCADE and REVLIMID. VELCADE currently dominates the market in first-line MM treatment in China, while VELCADE and REVLIMID share the market in the second line. Chinese guidelines recommend lenalidomide as a standard of care for the treatment of R/R and newly diagnosed MM as well as in the maintenance setting.
REVLIMID was listed on the National Reimbursement Drug List ("NRDL") in June 2017. On November 12, 2019, we announced that REVLIMID received formal inclusion on the NRDL in China for R/R multiple myeloma. On December 22, 2019 we announced that our sNDA for the use of REVLIMID in R/R indolent lymphoma was accepted by the NMPA.
VIDAZA
VIDAZA (azacitidine for injection) is a pyrimidine nucleoside analog that has been shown to reverse the effects of DNA hypermethylation and promote subsequent gene re-expression. VIDAZA was approved in China in April 2017 for the treatment of intermediate-2 and high-risk myelodysplastic syndromes ("MDS"), chronic myelomonocyte leukemia ("CMML") and acute myeloid leukemia ("AML") with 20% to 30% blasts and multi-lineage dysplasia. In January 2018, VIDAZA became commercially available in China.
MDS are a group of cancers in which immature blood cells in the bone marrow do not mature and therefore do not become healthy blood cells. Approximately seven per 100,000 people are affected with approximately four per 100,000 people newly acquiring the condition each year globally according to Germing et al., 2013. The typical age of onset is 70 years. The higher-risk MDS (intermediate-2 and high-risk MDS) is considered fatal because the median overall survival rate is only 0.4-1.1 years and nearly 30% of these patients progress to AML, according to the U.S. National Comprehensive Cancer Network ("NCCN"), MDS guideline 2013 and MDS Foundation.
In China, the main treatments for intermediate-2 and high-risk MDS are conventional care regimen ("CCR") (best supportive care, low-dose cytarabine and intensive chemotherapy), and hypomethylating agents ("HMAs"). DACOGEN® (decitabine) marketed by Johnson & Johnson was the first HMA agent approved in China in 2009. In the past several years, at least six decitabine generics have become available. In 2017, decitabine was listed in the NRDL. Nevertheless, there are still over 50% of higher-risk MDS patients treated with CCR and the unmet need remains large.
VIDAZA is the only approved HMA shown to prolong survival for patients with MDS. Besides reversing the effects of DNA hypermethylation, VIDAZA inhibits protein synthesis via RNA incorporation. VIDAZA is a Category 1 recommended treatment for patients with intermediate-2 and high-risk MDS, according to the U.S. NCCN guideline. It is also a first-line recommended treatment for patients with intermediate-2 and high-risk MDS, according to the Chinese MDS treatment guidelines, and was listed on the NRDL in October 2018.
We are planning to commercialize the following cancer drugs in China under an exclusive license from Amgen:
XGEVA
XGEVA (denosumab) is an antibody-based RANK ligand ("RANKL") inhibitor that was approved globally for the prevention of skeletal-related events ("SREs") in patients with multiple myeloma, for the prevention of SREs in patients with bone metastases from solid tumors and for treatment of adults and skeletally mature adolescents with giant cell tumor of bone ("GCTB"). XGEVA is approved in over 70 countries worldwide. In China, it was approved in 2019 for patients with GCTB and is in development in China for prevention of skeletal-related events in cancer patients with bone metastases.
KYPROLIS
KYPROLIS (carfilzomib), a proteasome inhibitor, has been approved in over 60 countries for use in patients with relapsed and/or refractory multiple myeloma ("RRMM"). It has been filed in China as a treatment for patients with MM, and the NDA has been accepted by the NMPA.

BLINCYTO
BLINCYTO (blinatumomab), a bispecific CD-19 directed CD3 T-cell engager, is the first and only approved bi-specific T-cell engager ("BiTE") immunotherapy. It has been approved in 60 countries for use in patients with acute lymphoblastic leukemia ("ALL"). It has been filed in China as a treatment for adult patients with R/R ALL, and the NDA has been accepted and granted priority review by the NMPA.
We are planning to commercialize the following cancer drugs in China under an exclusive license from EUSA Pharma:
SYLVANT
SYLVANT (siltuximab), an interleikin-6 (IL-6) antagonist, that was approved as a treatment for patients with idiopathic multicentric Castleman disease who are human immunodeficiency virus ("HIV") negative and human herpesvirus-8 ("HHV-8") negative. It has been been listed for fast-track approval in China by the NMPA under its Review and Approval Procedures for Urgently-Needed Pharmaceutical Drugs Developed Overseas.
QARZIBA
QARZIBA (dinutuximab beta), a mouse-human chimeric monoclonal lgG1 antibody, that was approved as a treatment of high-risk neuroblastoma in patients aged 12 months and above, who have previously received induction chemotherapy and achieved at least a partial response ("PR"). It has been been listed for fast-track approval in China by the NMPA under its Review and Approval Procedures for Urgently-Needed Pharmaceutical Drugs Developed Overseas.

Zanubrutinib, a BTK Inhibitor

BGB-3111

Zanubrutinib, is a potent and highly selective small molecule inhibitor of BTK inhibitor. We arethat is approved in the United States for the treatment of MCL in adult patients who have received at least one prior therapy. It is currently developing BGB-3111being evaluated in a broad pivotal clinical program globally and in China as a monotherapy and in combination with other therapies for the treatment of a variety ofto treat various lymphomas. BGB-3111Zanubrutinib has demonstrated higher selectivity against BTK than ibrutinib, the onlyIMBRUVICA (ibrutinib), an approved BTK inhibitor, currently approved by the FDA and the European Medicines Agency, or EMA, based on our biochemical assays andassays; higher exposure than ibrutinib based on their respective Phase 1 experience.


        In addition, we believe BGB-3111 is the only BTK inhibitor that has demonstratedexperience in separate studies; and sustained target inhibition in disease-relevant tissues. Our preclinical data show that target inhibition by ibrutinib at disease relevant tissues, such as the lymph node, bone marrow, and spleen, in mice and rats was not sustained over a 24-hour period. Published clinical data on ibrutinib show that ibrutinib's target inhibition in the blood is borderline at the approved dose of 420 mg once a day, with BTK occupancy in a significant portion of patients below 80%.


Target Inhibition by Ibrutinib Is Incomplete

        As of March 20, 2017, we have enrolled over 340 patients in monotherapy and combination trials of BGB-3111. In January 2017, we initiated a global, multi-center randomizedfrom our Phase 3 ASPEN study which compared zanubrutinib with ibrutinib in WM. While the trial did not achieve statistical significance on its primary endpoint of superiority in Waldenström's Macroglobulinemia, or WM that will enroll approximately 170 patients at clinical sites in North America, Europe, Australia,complete response and New Zealand. Subsequently, in March 2017, we initiated two single-arm, open-label, multi-center, pivotal studies in China in relapsed or refractory chronic lymphocytic leukemia, or CLL, or small lymphocytic lymphoma, or SLL, and in relapsed or refractory mantle cell lymphoma, or MCL, respectively. In addition, we have completed the dose-escalation phase of our Phase 1 trial in Australia, and we are continuing the dose-expansion phase in patients with select lymphoid malignancies including CLL, diffuse large B-cell lymphoma, or DLBCL, follicular lymphoma, or FL, MCL, marginal zone lymphoma, or MZL, WM, hairy cell lymphoma, or HCL. In the completed dose-escalation phase of our clinical trial, no protocol-defined dose-limiting toxicities were observed. BGB-3111 achieved several-fold higher exposure levelsvery good partial response (“VGPR”) rates for


zanubrutinib compared to that seen for the approved doses of ibrutinib. Proof-of-concept has been established for BGB-3111 with clinical data indicating that BGB-3111 isibrutinib, zanubrutinib demonstrated a potent BTK inhibitor with anti-tumor activity observedhigher VGPR rate as well as improvements in multiple types of lymphomas starting at the lowest dose tested, 40 mg once daily, or QD. We have also initiated a combination study in Australiasafety and the United States with obinutuzumab, an anti-CD20 monoclonal antibody approved for CLL.

tolerability.

Mechanism of Action

BTK is a key component of the B-cell receptor or BCR,("BCR"), signaling pathway and is an important regulator of cell proliferation and cell survival in various lymphomas. BTK inhibitors block BCR-induced BTK activation and its downstream signaling, leading to growth inhibition and cell death in certain malignant white blood cells called B-cells. BGB-3111Zanubrutinib is an orally active inhibitor of BTK that covalently binds to the cysteine Cys-481 of BTK, resulting in irreversible inactivation of the kinase. It has also been shown that BTK inhibitors can inhibit solid tumor growth by regulating the tumor microenvironment in preclinical animal models.

Market Opportunity

        Lymphomas are a group of blood-borne cancers involving lymphatic cells of the immune system. They can be broadly categorized into non-Hodgkin's lymphomas, chronic B-cell leukemias, predominantly CLL, and acute B-cell leukemias. Depending on the origin of the cancer cells, lymphomas are also characterized as B-cell or T-cell lymphomas. B-cell lymphomas make up approximately 85% of non-Hodgkin's lymphomas and comprise a variety of specific diseases involving B-cells at differing stages of maturation or differentiation. Preliminary data from animal models involving BGB-3111 and third-party BTK inhibitors also suggest potential applications in solid tumors and inflammatory diseases, which could substantially expand our market opportunity.

Current Therapies and Limitations

        Conventional methods of treatment of lymphomas vary according to the specific disease or histology, but generally include chemotherapy, antibodies directed at CD20, and, less frequently, radiation. Recently, significant progress has been made in the development of new therapies for lymphomas, including BCR signaling inhibitors, primarily with the BTK inhibitor ibrutinib and the PI3K delta inhibitor idelalisib. In addition, there are other inhibitors of BCR signaling pathways in development, such as PI3K delta/gamma, IRAK4 and SYK.

        The BTK inhibitor ibrutinib was first approved by the FDA in 2013 for the treatment of patients with MCL who have received at least one prior therapy. Since 2013, ibrutinib has received supplemental FDA approvals for the treatment of patients with CLL, CLL patients with 17p deletion, patients with WM, and MZL patients who have received at least one prior anti-CD20-based therapy. Ibrutinib is also approved by the EMA for treatment of patients with MCL, CLL, or WM. Ibrutinib has subsequently been approved in over 40 countries, but not China. Reported global sales of ibrutinib were approximately $2 billion in 2016.

        Despite the clinical and commercial success of ibrutinib, we believe based on its product profile that meaningful differentiation is possible in at least the following aspects:

    Safety and tolerability.  Although ibrutinib has shown a favorable safety profile compared to traditional chemotherapies, it is associated with adverse reactions that can limit its tolerability as a chronic treatment and in some cases can be treatment-limiting or life-threatening. These adverse reactions—including diarrhea, thrombocytopenia, or low blood platelet count, bleeding and AF—are believed to be due to ibrutinib's broad inhibition of kinases other than BTK, including EGFR, JAK3 and TEC.

    Sustainable target inhibition in disease originating tissue.  Although ibrutinib induced sustained BTK inhibition when measured in the plasma of patients, our preclinical studies of ibrutinib show that target inhibition in disease-relevant tissues, such as the lymph node, bone marrow and spleen, in mice and rats was not sustained over a 24-hour period.

    Oral bioavailability.  Ibrutinib has shown 7–23% oral bioavailability in preclinical studies, as evidenced by the daily dose of 420 mg or 560 mg required in the clinic.
enzyme.

    Combinability with ADCC-dependent antibodies.  Anti-CD20 agents, such as rituximab, obinutuzumab and ofatumumab, are considered effective therapies for lymphomas. Several preclinical studies have demonstrated that ibrutinib, potentially due to its inhibitory activity against ITK, interferes with rituximab-medicated ADCC, which is the mechanism by which rituximab and other anti-CD20 antibodies are believed to exert their immune defense activities. Therefore, these preclinical data suggest that the activity of rituximab and other ADCC-dependent antibodies may be reduced when combined with ibrutinib.

Potential Advantages of BGB-3111

        We believe, based on our preclinical and clinical data, that BGB-3111 has the potential to be differentiated from ibrutinib in the following respects:

    Better safety and tolerability.  Based on our preclinical studies, we believe BGB-3111 is more selective than ibrutinib in the inhibition of BTK and has less off target inhibition of other kinases, including EGFR, ITK, JAK3, HER2 and TEC, which we believe are associated with ibrutinib toxicity. Results from our preclinical biochemical and cellular assays show that BGB-3111 has similar potency for BTK as compared to ibrutinib while being less active against other kinase targets than ibrutinib, as reflected by the higher dose required to inhibit half the enzymatic activity, or IC50 . Based on the selectivity of BGB-3111 relative to ibrutinib, a 2- to 70-fold higher concentration of BGB-3111 is required to achieve similar levels of inhibition in these other targets as compared to ibrutinib. Therefore, BGB-3111 has the potential to be associated with fewer toxicities.

    More sustained inhibition in disease originating tissue.  In our preclinical studies, BGB-3111 has demonstrated favorable pharmacokinetic properties. The comparatively high drug level of BGB-3111 in disease originating tissue as demonstrated in the clinic could potentially translate into a more complete and sustainable inhibition and a better quality of response than ibrutinib. Ibrutinib demonstrated a dose-dependent BTK occupancy in PBMCs, during its dose-escalation study. However, even at 420 mg, its approved dose for CLL, ibrutinib did not achieve complete or sustained target occupancy in PBMCs in a significant proportion of patients. In addition, BGB-3111's favorable safety profile may allow higher drug exposure, which could result in more sustained target inhibition. Available data from our completed dose-escalation trial suggest that BGB-3111 achieved several fold higher exposure levels compared to that achieved by the approved doses of ibrutinib in its Phase 1 study. Paired biopsy data from our Phase 1 study in Australia indicate that BGB-3111 is able to sustainably inhibit BTK in the lymph node, especially with 160 mg twice daily, or BID dosing.

    Better oral bioavailability.  BGB-3111 has shown oral bioavailability of 25–47% in our preclinical animal studies. Based on human data generated in our dose-escalation trial compared to reported data for ibrutinib, BGB-3111 has better oral bioavailability than ibrutinib. Pharmacokinetic data from our clinical studies show a robust and dose-dependent increase in drug exposure and the drug exposure of BGB-3111 at 80 mg QD was comparable to that reported for ibrutinib at 560 mg QD. In addition, the free drug concentration of BGB-3111 at 40 mg QD was comparable to that reported for ibrutinib at 560 mg QD. Lastly, pharmacokinetics data for BGB-3111 suggest that there appears to be far less interpatient variability in drug exposure as compared to ibrutinib.

    Better combinability with ADCC-dependent antibodies.  Our preclinical data show that BGB-3111 has less off-target inhibition for ITK than ibrutinib in biochemical and cell models. BGB-3111 displayed a more limited inhibitory effect on rituximab-induced ADCC than ibrutinib in cell-based studies. In a human MCL xenograft model the addition of rituximab to ibrutinib did not improve tumor activity as compared to ibrutinib as a monotherapy. However, the

      combination of rituximab and BGB-3111 demonstrated improved anti-tumor activity as compared to either as a monotherapy. We believe this may translate into better activity in patients when BGB-3111 is combined with rituximab or other ADCC-dependent antibody therapies.

Summary of Clinical Results

As of March 20, 2017, over 340January 15, 2020, we had enrolled more than 2,500 patients have been enrolled in monotherapy and combinationclinical trials of BGB-3111. Preliminary data from our Phase 1 trial suggest that BGB-3111 is well-tolerated. Thezanubrutinib, including trials of zanubrutinib in combination with other therapies, which we refer to as combination trials. A multi-center, open-label Phase 1 trial is being conducted in Australia, New Zealand, the United States, and South Korea and Europe to assess the safety, tolerability, pharmacokinetic properties and preliminary activity of BGB-3111zanubrutinib as a monotherapy in patients with different subtypes of B-cell malignancies, including CLL, DLBCL, FL, MCL, MZL,such as WM, CLL/SLL, follicular lymphoma ("FL"), and HCL. We have completed the dose-escalation phase, and we are currently in the dose-expansion phase.MCL. The initial results of the dose-escalation phase and dose-expansion phase of our clinicalthis trial showdemonstrated that, consistent with BGB-3111'szanubrutinib’s pharmacokinetic profile, complete and sustained 24-hour BTK occupancy in the blood was observed in all tested patients, starting at the lowest dose of 40 mg QD.once daily ("QD"). In addition, sustained full BTK occupancy was observed in the lymph node especially fornodes with the 160 mg BIDtwice-daily ("BID") dosing regimen. No protocol-defined dose-limiting toxicitiesWe substantially expanded the clinical development program for zanubrutinib based on these early results to include late stage clinical studies in WM, CLL/SLL, MCL, FL and MZL. In addition, we have several studies ongoing in DLBCL, both monotherapy and combinations, and we have several combination studies in CLL including combinations with the Bcl-2 inhibitor venetoclax and a planned study with our internally-discovered Bcl-2 inhibitor, BGB-14417. All of the studies discussed below were observedpresented at major medical conferences and onlywere the subject of a press release and a filing with the SEC. These sources have further details on each study. The first readout of our late-stage program was recently reported, the ASPEN study in WM (NCT03053440), discussed below.
Mantle Cell Lymphoma
We presented two data sets in MCL at the 15th International Conference on Malignant Lymphoma that took place on June 18-22, 2019 in Lugano, Switzerland (the "2019 ICML"), and it was these two data sets that formed the basis for our accelerated approval in MCL in adult patients who have received at least one prior therapy that we received from the U.S. FDA in November 2019.
The first trial (NCT03206970, also known as BGB-3111-206) is a single-arm, open-label, multi-center, pivotal Phase 2 trial of zanubrutinib as a monotherapy in patients with R/R MCL. The trial is being conducted in China and enrolled 86 patients who had received a median of two (1-4) prior lines of therapy. Patients were treated with zanubrutinib, dosed at 160 mg orally BID. The primary endpoint of the trial is overall response rate ("ORR") assessed by an independent review committee ("IRC") using PET-based imaging according to the Lugano Classification 2014. As of the February 15, 2019 data cutoff, 52 patients (60.5%) remained on study treatment. The median follow-up time for patients enrolled in the trial was 18.4 months (0.3-23.5).
The investigator-assessed ORR was 83.7% (72/86). The complete response ("CR") rate was 77.9% (67/86) and the PR rate was 5.8% (5/86). At an earlier data cutoff in March 2018 (8.2 months median follow-up), the ORR, CR and PR were 84.7%, 72.9%, and 11.8% per investigator assessment, and 83.5%, 58.8%, and 24.7% per IRC assessment, respectively. The 15-month PFS by investigator was estimated at 72.1%, and median PFS follow-up was 19.1 months (0.0-22.3). With 16.4 months median follow-up (2.3-19.5), the duration of response (DOR) by investigator at 15 months was 67.4%.
The second set of data was the MCL cohort of our BGB-3111-AU-003 study (NCT02343120). This open-label, multi-center Phase 1/2 trial of zanubrutinib as a monotherapy in patients with different subtypes of B-cell malignancies, including MCL, is being conducted in the United States, Australia, Italy, South Korea, New Zealand, and the United Kingdom. As of the December 13, 2018 data cut-off, 53 patients with treatment discontinuationsnaïve (TN, n=16) or R/R (n=37) MCL had been enrolled in the trial and the median follow-up time was 15.4 months (0.1-38.2). Forty-eight patients (all 37 R/R and 11 TN) were evaluable for efficacy with median follow-up time of 16.7 months (1.6-38.2) in this analysis, per the Lugano 2014 Classification. At the time of the data cutoff, 27 patients (13 TN and 14 R/R) remained on study treatment.
The investigator-assessed ORR was 85.4% (41/48); the CR rate was 29.2% (14/48) and the PR rate was 56.3% (27/48). The majority of patients were assessed via CT-scan; PET scan was optional per trial protocol. The median DOR was 16.2 months (0.03-28.2) for all patients. The median PFS for patients with R/R MCL was 17.3 months. Response rates shown in the table below from this study are for the 32 patients who had R/R disease and received the full 160mg BID dose of zanubrutinib.

The following table shows the efficacy data included in our label in the United States for BRUKINSA (zanubrutinib) for the treatment of adult patients with mantle cell lymphoma (MCL) who have received at least one prior therapy:

In the BGB-3111-206 study, the tolerability of zanubrutinib was generally consistent with previous reports of zanubrutinib treatment in patients with various B-cell malignancies. The majority of treatment-emergent adverse events ("TEAEs") were grade 1 or 2 in severity, with the most frequently reported being neutrophil count decreased (44.2%), upper respiratory tract infection (34.9%), rash (33.7%), white blood cell count decrease (31.4%), and platelet count decrease (25.6%). Grade 3 TEAEs were reported in 36 patients (41.9%), with the most frequently reported being neutrophil count decrease (18.6%), lung infection (7.0%), white blood cell count decrease (5.8%), and anemia (5.8%). Five patients (5.8%) had TEAEs leading to death (one case each of pneumonia, cerebral hemorrhage, traffic accident, and two cases of death with unknown cause). Among TEAEs of special interest for BTK inhibitors, hypertension was reported in 13 patients (15.1%), petechiae/purpura/contusion in four patients (4.7%), and major hemorrhage in three patients (3.5%); no cases of atrial fibrillation/flutter, secondary primary malignancy, or tumor lysis syndrome were reported in this trial.
In the BGB-3111-AU-003 study, the majority of adverse events ("AEs") were grade 1 or 2 in severity. The most frequently reported AEs included contusion (39.6%), diarrhea (34.0%), upper respiratory tract infection (26.4%), constipation (22.6%), fatigue (22.6%), and rash (18.9%). Grade 3 AEs were reported in 54.7% patients, with the most frequent being anemia (9.4%), myalgia (5.7%), cellulitis (5.7%), pleural effusion (5.7%), and pneumonia (5.7%). Discontinuation due to drug-related adverse events, or AES was reported asAEs occurred in 18.9% patients with two determined to be related to study drug (one case each of Octoberperipheral edema and subdural hematoma). There were five deaths due to AEs, which were all determined by the investigators to be unrelated to zanubrutinib treatment.
Waldenström’s Macroglobulinemia - ASPEN Study
On December 16, 2019, we announced topline results from our Phase 3 2016,ASPEN trial (NCT03053440) of zanubrutinib compared to ibrutinib for the most recent data analysis. Basedtreatment of patients with WM. The trial did not achieve statistical significance on the pharmacokinetics, pharmacodynamics,its primary endpoint of superiority in CR and very good partial response ("VGPR") rates for zanubrutinib compared to ibrutinib, but zanubrutinib demonstrated more frequent VGPRs (28.4% versus 19.2% in overall population) and advantages in safety and efficacy evaluationtolerability.
The ASPEN trial is a randomized Phase 3 trial in 229 patients with WM conducted in 61 centers in Europe, Australia, and the United States. ASPEN is the largest Phase 3 trial yet conducted in Waldenström's Macroglobulinemia and the first comparative trial readout for two BTK inhibitors. The study included two cohorts, a randomized cohort (cohort 1) consisting of BGB-3111201 patients with a MYD88 mutation and a non-randomized cohort (cohort 2) in which 28 patients with MYD88 wild-type ("MYD88WT") received zanubrutinib because MYD88WT patients have historically responded poorly to ibrutinib therapy. The randomized cohort 1 enrolled 102 patients (including 83 R/R patients and 19 treatment-naïve ("TN") patients) in the dose-escalation phase,zanubrutinib arm and 99 patients (including 81 R/R patients and 18 TN patients) in the ibrutinib arm. Patients in the zanubrutinib arm were assigned to receive zanubrutinib 160 mg BID has been selected as the Phase 3 dose. Proof-of-concept has been established for BGB-3111 with clinical data suggesting that BGB-3111 is a potent BTK inhibitor with objective anti-tumor activity observed in multiple types of lymphomas including CLL, MCL, and WM.


        The chart below shows the pharmacokinetic profile of BGB-3111 from this Phase 1 trial, in comparison to historical data with ibrutinib and acalabrutinib.

Waldenström’s Macroglobulinemia and Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma
In general, the most recent data analysis,that we have presented on the use of zanubrutinib in patients with WM and CLL/SLL are consistent with our earlier data, which hadwe believe supports our pursuit of a cutoffbroad development program including these two indications. Data from several trials investigating the use of October 3, 2016, AEszanubrutinib in WM and CLL/SLL were generally mild in severity, self-limited, and usually encountered only inpresented during 2019. At the earlier part24th Congress of the European Hematology Association that took place on June 13-16 in Amsterdam (the "2019 EHA"), we presented data from the MYD88WT cohort of the ASPEN study (NCT03053440) as well as the WM cohort of our first-in-human global Phase 1/2 study (NCT02343120). At the 2019 ICML, we reported on two data sets, our pivotal Phase 2 results (NCT03206918) and a combination study with obinutuzumab (NCT02569476). We also reported data in CLL/SLL from two studies at the 61st American Society of Hematology ("ASH") Annual Meeting in Orlando, FL from Arm C of the SEQUOIA trial (NCT03336333) in patients with the deletion of chromosome 17p13.1 (del17p) and from the CLL/SLL cohort of our first in man global Phase 1/2 study (NCT02343120). Data from these studies and the other studies summarized in this Annual Report were included in press releases issued at the time of the medical conferences and included in our current reports or announcements filed with the SEC and HKEx, respectively.
Other Lymphomas
We are also investigating zanubrutinib for the treatment course.of patients with several other lymphomas. We have studies ongoing in FL, MZL, and DLBCL, and we reported data from two FL studies in 2019, one monotherapy study and one in combination with obinutuzumab. Results from the combination study with obinutuzumab (NCT02569476) in FL were presented at the 2019 ICML, while data in FL from our Phase 1 study (NCT03189524) in Chinese patients were reported at the 22nd Annual Meeting of the Chinese Society of Clinical Oncology that took place September 18-22, 2019 in Xiamen, China (the "2019 CSCO").

Analysis of Safety Data from Monotherapy Trials
Pooled safety data from 682 patients enrolled in six ongoing, Phase 1 and Phase 2 clinical trials of zanubrutinib monotherapy, for WM, MCL, CLL/SLL, DLBCL and other B-cell malignancies were presented at the 2019 EHA. The majority of patients had R/R disease; almost all patients received zanubrutinib at a dose of 320mg QD or 160mg BID. The median duration of zanubrutinib exposure was 13.4 months (0.1-49.7). This analysis included an evaluation of the frequency and severity of AEs, AEs of special interest (AESIs), and AEs leading to death, dose reduction, or treatment discontinuation. Ninety-seven percent of patients reported at least one AE, which were primarily grade 1 or 2. The most frequentcommon AEs (³20%) of any attribution wereall grades included upper respiratory tract infection (39%(32.4%), petechiae (spots that appear on the skin as a result of bleeding) / purpura (subcutaneous bleeding) / contusion (33%), nausea (24%neutrophil count decreased (25.2%), diarrhea (24%(19.4%), cough (19.1%), contusion (18.6%), and constipation (21%rash (18%). The most common grade 3 AEs included neutrophil count decreased (14.4%), all grade 1 or 2anemia (7.6%), neutropenia (6.6%), pneumonia (4.5%), platelet count decreased (4.3%), and lung infection (4.1%). Serious AEs (SAEs), consisting primarily of infectious complications such as pneumonia/lung infection, were reported in severity except for one case36% of diarrhea (3%). Four serious adverse events, or SAEs, were assessedpatients. AESIs such as possibly related to BGB-3111, including one case each of grade 3 cryptococcal meningitis, grade 3 pneumonia, grade 2 atrial fibrillation, or AF,fibrillation/flutter (1.9%), major hemorrhage (2.5%), and grade 2 vomiting. Other grade 3 or greater events considered possibly relatedhypertension (3.4%) were infrequent, and treatment discontinuation due to BGB-3111 included two casesAEs was uncommon (9.1% overall, including 3.5% for whom the event(s) were treatment-related).
Clinical Development Plan
We received accelerated approval from the U.S. FDA in November 2019 for zanubrutinib for use in adult MCL patients who have received at least one prior therapy. In addition, zanubrutinib was granted Fast Track designation by the U.S. FDA for the treatment of neutropenia and one case each of diarrhea, hypertension, increased liver function test, pulmonary hypertension, and vomiting. In total, three cases of AF were reported (all grade 1 or 2), and two of the three occurred in patients with pre-existing AF. No serious hemorrhage (³ grade 3 hemorrhage or central nervous system, or CNS, hemorrhageWM in July 2018 and Breakthrough Therapy designation in January 2019 for the treatment of any grade) was reported. The only treatment discontinuation was due to exacerbation of pre-existing bronchiectasis in a patient who achieved a very good partial response, or VGPR, on BGB-3111, and the subsequent death of this patient was also the only fatal event in the study and was assessed by the investigator to be unrelated to study treatment.


        After a median follow-up of 9.6 months (3.0–24.7 months), 32 of the 33 patients were evaluable for response as one patient had IgM < 500 mg/dl at baseline. The rate of overall response, defined as minor response, or MR, or better, was 94%. The major response rate, defined as partial response, or PR, or better, was 78% (25 out of 32 patients). VGPRs (³90% reduction or normalization of IgM and reduction in lymphadenopathy / splenomegaly) have been observed in 34% (11 out of 32 patients) and PRs (50–89% reduction in IgM and reduction in lymphadenopathy / splenomegaly) in 44% (14 out of 32 patients) of patients to date. IgM decreased from a median of 32.5g/l at baseline to 4.0g/l, and hemoglobin increased from a median of 10.3g/dl at baseline to 13.6g/dl. There have been no cases of disease progression.


BGB-3111 Phase 1 Trial in WM: Efficacy Summary

MYD88 andCXCR4 mutational analysis results were available for 23 patients who were evaluable for response at the data cutoff. Of 18 evaluableadult patients with theMYD88L265P /CXCR4WT genotype, eight achieved VGPRs, seven achieved PRs, two achieved MRs, andMCL who have received at least one had stable disease, or SD. The two patients with theMYD88L265P /CXCR4WHIM genotype achieved a PR and an MR, respectively. Responses were also seen inMYD88WT patients, including one PR, one MR, and one SD among three evaluable patients. Analysis of patient response by genomic characteristics was ongoing.

        The depth of responseprior therapy. We plan to BGB-3111 in the Phase 1 trial improves with longer treatment. In 32 evaluable patients who had three cycles of BGB-3111 treatments, the VGPR rate was 6%, the PR rate was 59%, the MR rate was 25%, and the SD rate was 9%. The major response rate was 65%. In 25 evaluable patients who had six cycles of treatments, the VGPR rate improved to 28%, and the major response rate improved to 84%. In 15 evaluable patients who had 12 cycles of treatments, the VGPR rate improved to 53%, and the major response rate improved to 93%.

        The table below includes comparison of data of BGB-3111 to ibrutinib data at similar points of maturity. The major response rate in the BGB-3111 Phase 1discuss our ASPEN study presented at the International Workshop on Waldenström's Macroglobulinemia-9 conference, or IWWM-9, was 83%, and the VGPR rate was 33%. The data cutoff date for IWWM-9 was September 9, 2016. At similar early follow-up time points in two different studies, ibrutinib has a major response rate ranging from 57% to 65% and a VGPR rate of 6%.

        In addition to dataresults in WM updated data on BGB-3111with the FDA and EMA in patients with CLL from the dose-escalation and dose-expansion phases of the Phase 1 trial were presented on December 5, 2016 at the 2016 American Society of Hematology Annual Meeting. As of November 21, 2016, 63 patients with CLL or SLL, were enrolled in the study. The data presented were from a total of 46 CLL or SLL patients who had at least 12 weeks of follow-up or discontinued treatment prior to week 12, by the data cutoff of October 3, 2016.

        BGB-3111 was well-tolerated. Only one patient had discontinued BGB-3111 treatment for an AE, a grade 2 pleural effusion. The most frequent AEs (³ 20%) of any attribution were petechiae / purpura / contusion (48%), upper respiratory tract infection (33%), fatigue (28%), diarrhea (20%), cough (20%), and headache (20%), all of which were grade 1 or 2 in severity except for one case of grade 3 purpura. Three SAEs were assessed as possibly related to BGB-3111, including one case each of grade 2 cardiac failure, grade 2 pleural effusion, and grade 3 purpura. Other grade 3 or greater events considered possibly related to treatment included three cases of neutropenia and one case of AF, which was the only AF case reported. The case of purpura was the only major bleeding event; no other cases of serious hemorrhage (defined as³ grade 3 hemorrhage or CNS hemorrhage of any grade) were reported.


        The table below summarizes most frequent AEs (>=15%) independent of causality in our Phase 1 trial in WM and CLL cohorts.


BGB-3111 Phase 1 Safety: AEs Independent of Causality—BGB-3111 is Well-Tolerated in CLL/SLL and WM

        After a median follow-up of 8.6 months (2.2–20.9 months), the rate of overall response was 96% (44 out of 46 patients) with PR in 67% (31 out of 46 patients) and PR with lymphocytosis in 28% (13 out of 46 patients) of patients. SD was observed in 2% (1 out of 46 patients) of patients. The patient who discontinued prior to week 12 due to pleural effusion was not evaluable for response. No instances of disease progression or Richter's transformation had occurred.

        The figure below shows the median change of SPD from baseline over the treatment time. The tumor shrinkage improves over the time on treatment. Consistent with data we observed in a WM cohort, the response in CLL, in this case measured by change of SPD, appears to be deeper with BGB-3111.

        In January 2017 we initiated a global, multi-center randomized Phase 3 pivotal trial in WM in which we plan to enroll approximately 170 patients at clinical sites in North America, Europe, Australia, and New Zealand to determine whether the quality of response with BGB-3111 in WM is superior to that of ibrutinib. The study will compare BGB-3111 with ibrutinib in relapsed or refractory WM patients or treatment-naïve WM patients who are inappropriate for chemo-immunotherapy. Patients will be tested for mutation status of theMYD88 gene and assigned toMYD88 mutation and wildtype cohorts accordingly. We expect to enroll 150 patients in theMYD88 mutation cohorts, who will be randomized in a 1:1 ratio to receive either BGB-3111 160 mg orally BID or ibrutinib 420 mg orally QD until progression. The primary endpoint is combined rate of complete responses, or CRs, and VGPRs. Secondary endpoints include major response rate, progression-free survival, duration of response, and symptom resolution. The randomization will be stratified byCXCR4 mutational status and number of lines of prior therapy. Approximately 20 patients withMYD88 wildtype status will be enrolled in the second cohort and receive BGB-3111. The patients will be evaluated for the combined rate of CRs and VGPRs, major response rates, and safety. Below schematic shows the design of the Phase 3 pivotal trial in WM.



BGB-3111 Phase 3 Study Design in WM

        Moreover, we are evaluating BGB-3111 in combination clinical trials. Our preclinical data show that BGB-3111 has less off-target inhibition for ITK than ibrutinib in biochemical and cell models. BGB-3111 displayed a more limited inhibitory effect on rituximab-induced ADCC than ibrutinib in cell-based studies. As shown in the graph below, in a human MCL xenograft model the addition of rituximab to ibrutinib did not improve tumor activity as compared to ibrutinib as a monotherapy. However, the combination of rituximab and BGB-3111 demonstrated improved anti-tumor activity as compared to either as a monotherapy. We believe this may translate into better activity in patients when BGB-3111 is combined with rituximab or other ADCC-dependent antibody therapies. We initiated the combination trial with CD20 antibody obinutuzumab in patients with B-cell malignancies in January 2016, and this trial is currently in its dose-expansion phase.

        We also explored the combination of BGB-3111 and our PD-1 antibody, BGB-A317 in two DLBCL primary tumor models. In both models, BGB-3111 showed weak monotherapy activity. When used as a monotherapy BGB-A317 was only active in the PD-L1 positive tumor. However, the combination of BGB-3111 and BGB-A317 was highly active, better than either monotherapy, and induced tumor regression in both PD-L1 positive and PD-L1 negative models. A combination clinical trial of BGB-3111 with BGB-A317 was initiated in June 2016 and is in its dose-escalation phase.


BGB-3111 Combination Potential: Strong Rationale to Combine Our BTK and PD-1 Inhibitors

2020. In China, we have initiated two pivotal studiesannounced the acceptance of our filings for BGB-3111. In March 2017,approval in R/R MCL and R/R CLL/SLL in August 2018 and October 2018, respectively, and we initiated single-arm, open-label, multi-center pivotal clinical trialsexpect approval for both indications in the first half of BGB-3111 monotherapy2020. We also expect to submit a sNDA in China for zanubrutinib for the treatment of R/R WM in

2020.

patients with relapsedBased on the clinical data to date, we believe that zanubrutinib has a potentially best-in-class profile, and we are running a broad global pivotal program in multiple indications, including nine registration or refractory MCLregistration-enabling clinical trials. Four of the nine studies are Phase 3 and five are designed to be registration-enabling Phase 2.

We have an ongoing monotherapy head-to-head Phase 3 trial versus ibrutinib in patients relapsedWM (ASPEN), which has reported topline results and refractory CLL or SLL, respectively. The primary endpoint in each of these trialsstudy follow-up is the objective response rate, and secondary endpoints include progression free survival, duration of response, time to response, safety, and tolerability. We believe BGB-3111 is the first BTK inhibitor being developed in China under the Category 1.1 domestic regulatory pathway to enter into human testing and to present clinical data.

underway. We plan to expand our registration programreport full ASPEN study details at a medical conference in 2020. We are also conducting an ongoing Phase 3 trial compared to bendamustine and rituximab in patients with treatment-naive ("TN") CLL/SLL (SEQUOIA) and a head-to-head Phase 3 trial in R/R CLL/SLL versus ibrutinib (ALPINE). We have completed patient enrollment in SEQUOIA and expect interim results as early as 2020. We also expect to finish expanded patient enrollment in ALPINE in 2020. Our fourth Phase 3 trial is an ongoing Phase 3 confirmatory trial in patients with TN MCL. Additionally, we have five ongoing Phase 2 trials that are designed to be registration-enabling, including four monotherapy studies in R/R MCL, R/R WM, R/R CLL/SLL, and R/R MZL (MAGNOLIA) and an ongoing pivotal Phase 2 trial in combination with GAZYVA® (obinutuzumab) in patients with R/R FL (ROSEWOOD), which is designed as a pivotal trial for BGB-3111. In addition,accelerated or conditional approval and will require a confirmatory study. Finally, we plan to present data from theare also investigating zanubrutinib in several combination studies in DLBCL and CLL/SLL, including two studies in CLL/SLL investigating venetoclax combinations.

Tislelizumab, an anti-PD-1 Antibody

BGB-A317

Tislelizumab is an investigationala humanized monoclonal antibody against the immune checkpoint receptor PD-1. We are developing BGB-A317PD-1 that is currently being evaluated in pivotal clinical trials globally and in China and for which we plan to commence additional pivotal trials as a monotherapy and as ain combination agent forwith standard of care to treat various solid-organsolid and blood-bornehematological cancers. PD-1 is a cell surface receptor that plays an important role in down-regulating the immune system by preventing the activation of certain types of white blood cells called T-cells. PD-1 inhibitors remove the blockade of immune activation by cancer cells. We believe BGB-A317 may be differentiated from the currently approved PD-1 antibodies with the ability to bind Fc gamma receptor I specifically engineered out, and we believe this could potentially result in improved activities. In addition, BGB-A317 has a unique binding signature to PD-1 with high affinity and superior target specificity.

        We are evaluating BGB-A317 in the ongoing dose-escalation phase of our clinical trial in relapsed or refractory solid tumor patients and combination trials with our PARP inhibitor, BGB-290 and with our BTK inhibitor, BGB-3111 respectively, in Australia. As of March 20, 2017, we have dosed over 400 patients with BGB-A317 in monotherapy and combination trials. BGB-A317 is the first drug candidate produced from our immuno-oncology biologic programs, and we believe it could serve as one of the cornerstones for our immuno-oncology combination platform.

Mechanism of Action

Cells called cytotoxic T-cellsT-lymphocytes ("CTLs") provide humans an important self-defense mechanism against cancer, patrolling the body, recognizing cancer cells due to immunogenic features that differ from normal cells, and killing cancer cells by injecting poisonousdeleterious proteins into them. T-cellsT-lymphocytes have various mechanisms built into them that prevent them from damaging normal cells, among which is a protein called PD-1 receptor, whichthat is expressed on the surface of T-cells. The mostT-lymphocytes. PD-L1 is an important signaling protein that couldcan engage PD-1 is calledPD-1. PD-L1 which binds thebinding to PD-1 receptor and sends an inhibitory signal inside the T-cell, stopping it from making more poisonous proteinsT-lymphocyte and killing the cells sending the signal via PD-L1 and other cells nearby.suppresses its cytotoxic effects. Many types of cancer cells have hijacked the PD-L1 expression system that normally exists in healthy cells.

By expressing PD-L1, cancer cells protect themselves from being killed by cytotoxic T-cells. BGB-A317CTLs. Anti-PD-1 therapies are designed to bind to and block downstream activity of PD-1, allowing the immune system to combat cancer cells.
Tislelizumab is a monoclonal antibody designed to specifically bind to PD-1, without activating the receptor, thereby preventingblocking engagement of PD-1 by its ligands PD-L1 from engaging PD-1. Therefore, we believe BGB-A317and PD-L2. Tislelizumab has the potential to restore the cytotoxic T-cell's ability to kill cancer cells.

Market Opportunity

        Forecasts of the marketdemonstrated high affinity and specificity for monotherapy PD-1 and PD-L1 antibodies have increased as new tumor types responding to these antibodies have been identified and data has accumulated regarding their potential efficacy.in preclinical studies. It is estimated that these inhibitors will have sales in excess of $36 billion by 2023 across 10 tumors that are the focus of current immune-oncology studies (i.e., melanoma, renal cell cancer, lung cancer, gastric cancer, bladder cancer, HNSCC, triple-negative breast cancer, Hodgkin's lymphoma, Merkel cell carcinoma, and liver cancer).


        Tumor types that have been shown to be responsive to a PD-1 antibody include those with the highest annual incidence and mortality rates in China. Specifically, in 2012, 38%, 49%, 45%, and 51% of the worldwide mortalities from lung, esophageal, gastric, and liver cancers respectively occurred in China. Collectively, these four tumor types comprised over 1.6 million new cases in 2012 in China alone, according to the World Health Organization. To our knowledge, BGB-A317 is the first PD-1 antibody developed in China to enter clinical trials and to present clinical data. Due to a distinct regulatory pathway for drug candidates manufactured in China, we believe that BGB-A317 will become an important participant in China's PD-1 antibody and immuno-oncology market.

Potential Advantages of BGB-A317

        We believe BGB-A317 may be differentiated mechanistically from the currently approved PD-1 antibodies. Specifically, its ability to bind FcgRI has been engineered out, resulting in a cell biology differentiation compared to the currently approved PD-1 antibodies. Our preclinical data and published literature findings, Dahan et al., 2015, suggest that engagement of FcgRI may compromise the efficacy of anti-PD-1 antibodies by attracting immune suppressive cells and depleting thean engineered Fc region designed to minimize binding to FcγR on macrophages, thereby abrogating antibody-dependent phagocytosis, a potential mechanism of T-cell population necessary for attacking the tumor cells. With limited to no ability to bind to the receptor,clearance, which we believe BGB-A317 couldmay minimize potentially have improved activities. In addition, BGB-A317 has a unique binding signature to PD-1negative interactions with high affinity and superior target specificity. Inother immune cells based on preclinical studies, BGB-A317 showed better cellular functional activities in blocking PD-1 mediated reverse signal transduction and in activating human T-cells and primary PBMCs and improved tumor growth inhibition compared to currently approved PD-1 antibodies.

        We believe there could be a large commercial opportunity in China for PD1 antibodies as currently available clinical data suggest that some of the most prevalent cancers in China such as lung, gastric, liver and esophageal cancers are responsive to this class of agents. We believe we are well positioned to take advantage of this opportunity. In addition, the potential to combine BGB-A317 with our multiple clinical-stage and preclinical drug candidates provides us with additional shots on goal. Based on our preclinical data, we believe a strong rationale exists for combining BGB-A317 with our drug candidates BGB-290, BGB-3111, and BGB-283. In addition, we are developing several immuno-oncology candidates that we intend to combine with BGB-A317.

Summary of Clinical Trials

Results

As of March 20, 2017,January 15, 2020, we have dosedhad enrolled over 4005,100 patients in clinical trials of tislelizumab, including combination trials. Data from our trials thus far suggested that tislelizumab was generally well-tolerated and exhibited anti-tumor activity in a variety of tumor types. All of the studies discussed below were presented at major medical conferences and were included in press releases issued at the time of the medical conferences and included in our current reports or announcements filed with the SEC and HKEx, respectively.
Hodgkin’s Lymphoma
On December 26, 2019 tislelizumab received approval from the NMPA for the treatment of patients with BGB-A317cHL, who have received at least two prior therapies based on the results of a pivotal Phase 2 study (NCT03209973). Data from that study were presented on June 14, 2019 at the 2019 EHA meeting. The single-arm, multi-center, pivotal Phase 2 study of tislelizumab as a monotherapy in either monotherapy or combination trials. In April 2016, we completed the enrollment for the ongoing dose-escalation phase, and in May 2016, we initiated the dose-expansion phase of our Phase 1 clinical trial in relapsed or refractory solid tumorpatients with R/R cHL enrolled 70 patients in Australia, New Zealand,China who were either R/R to autologous stem cell transplantation ("ASCT"), or received at least two prior lines of systemic therapy for cHL and were not candidates for ASCT. Patients were treated with tislelizumab, dosed at 200 mg intravenously every three weeks. The primary endpoint of the United States, Korea, and Taiwan.

Tislelizumab was generally well-tolerated. There were 105 patients with >1 treatment-related adverse event ("TRAE"); the most common TRAEs of any grade were anemia (26.5%), decreased appetite (18.6%), pyrexia (16.8%), aspartate aminotransferase increased (15%), and pruritus (15%). Thirty-nine patients experienced grade >3 TRAEs related to the study drug. The most common grade >3 TRAEs were anemia (7.1%), urinary tract infection (4.4%), decreased appetite (3.5%), and hyponatremia (3.5%). Twelve (11%) patients experienced AEs related to the study drug that resulted in treatment discontinuation. SAEs related to study treatment were reported in 11 (9.7%) patients.
Immune-related TEAEs ("irTEAEs") occurred in 64% of patients. Common irTEAEs included immune-mediated skin adverse reaction (34%), immune-mediated hepatitis (24%), thyroid disorders (13%), and immune-mediated nephritis and renal dysfunction (12%).
Four (3.5%) patients experienced AEs with fatal outcome, including hepatic failure (n=2), respiratory arrest (n=1), and renal impairment (n=1). The events of hepatic failure and respiratory arrest were reported as possibly related to the study drug by the investigator. The event of Septemberrenal impairment was reported as possibly unrelated to the study drug.
Non-Small Cell Lung Cancer
On January 21, 2020 we announced that the pivotal Phase 3 trial (NCT03594747) evaluating our anti-PD-1 antibody tislelizumab in combination with two chemotherapy regimens for the first-line treatment of patients with squamous NSCLC met the primary endpoint of improved PFS at the planned interim analysis, as assessed by IRC. In this Phase 3, randomized, open-label, multi-center trial, patients with previously untreated advanced squamous NSCLC were randomized to receive either tislelizumab in combination with paclitaxel and carboplatin, tislelizumab in combination with ABRAXANE (nanoparticle albumin-bound (nab) paclitaxel) and carboplatin, or paclitaxel and carboplatin alone. Patients enrolled into the study were from China and had untreated stage IIIB or IV squamous NSCLC, regardless of PD-L1 expression. The primary endpoint is PFS per IRC. 360 patients were randomized 1:1:1 to receive tislelizumab (200mg every three weeks) in combination with each of the chemotherapy regimens or chemotherapy only, until disease progression, unacceptable toxicity, physician decision or consent withdrawal. Patients on the chemotherapy-only control arm who experienced disease progression, verified by central independent review, were eligible to cross over to receive tislelizumab monotherapy. The safety profile of tislelizumab in both combinations in this trial was consistent with the known risks of each study treatment, and no new safety signals were identified. Squamous NSCLC remains a significant unmet need, representing approximately 30 2016, anti-tumor activitiespercent of patients with NSCLC in China. Chinese NSCLC patients have a low rate of driver mutations, and as such are not candidates for therapeutic approaches that target such driver mutations.
In addition to the above study result, data from a Phase 2 trial in advanced lung cancer were observedpresented at the 2019 CSCO. This lung cancer study is an open-label, multi-cohort pivotal Phase 2 clinical trial (NCT03432598) of tislelizumab in 15combination with chemotherapy as first-line treatment for patients with advanced lung cancer, being conducted in China. Patients with non-squamous NSCLC were treated with tislelizumab at a dose of 200mg and doublet chemotherapy on day one of each three-week cycle; chemotherapy was given for up to four cycles, with pemetrexed and tislelizumab continued as scheduled if clinically appropriate. Patients with squamous NSCLC (two cohorts) and small cell lung cancer ("SCLC"), were treated with tislelizumab at a dose of 200mg and doublet chemotherapy every three weeks, for four to six cycles, with tislelizumab continued as scheduled if clinically appropriate. Efficacy data presented included a confirmed ORR of 67%, with

no patients having a CR. More specifically, the confirmed ORR was 43.8% (7/16) in patients with non-squamous NSCLC; 80.0% (12/15) in patients with squamous NSCLC (cohort A); 66.7% (4/6) in patients with squamous NSCLC (cohort B); and 76.5% (13/17) in patients with SCLC.
Esophageal Squamous Cell Carcinoma ("ESCC") and Nasopharyngeal Cancer
During 2019 data from several other studies evaluating tislelizumab in patients with esophageal and nasopharyngeal cancers were presented. The data from esophageal cancer patients was from a Phase 2 trial in esophageal and gastric or gastroesophageal junction carcinoma being conducted in China. Patients were treated with tislelizumab at a dose of 200mg and cisplatin on day one, and fluorouracil (5-FU) on days one through five during each 21-day cycle. Data presented at a median follow-up time of 13 months showed an ORR of 47%, with no patients having a CR.
The nasopharyngeal cancer ("NPC") data was from a cohort of our Phase 1/2 study of tislelizumab in China. The multi-center, open-label trial of tislelizumab in China as monotherapy in advanced solid tumors consists of a Phase 1 dose verification and pharmacokinetics component and a Phase 2 component of indication expansion in disease-specific cohorts, including patients with NPC solid tumors. Data presented at the American Society of Clinical Oncology ("ASCO") were from 21 patients with NPC, of whom 20 were enrolled in the Phase 2 indication-expansion portion of the trial. Patients were treated with tislelizumab at a dose of 200 mg every three weeks. Data presented at a median follow-up time of 7.6 months showed an ORR of 23% and a CR rate of 8%.
Other Tumor Types
In addition to the studies discussed above, we are evaluating tislelizumab for the treatment of patients with a PRbroad array of tumor types including gastric, head and neck, ovarian, natural killer/T-cell and liver cancers as well as cancers that are microsatellite instability-high ("MSI-high") or deficient mismatch repair ("dMMR").
Safety Results
The safety results of tislelizumab in clinical trials to date are consistent with its therapeutic class, having a relatively low rate of drug-related grade 3 or above toxicity. Across the monotherapy studies, the safety results were consistent with our two Phase 1 studies, and our first-in-human Phase 1 study. TEAEs are indicated in the table immediately below. Over half of the patients in our two Phase 1 studies experienced a tislelizumab-related TEAE, though ≥ grade 3 events were less frequent (8% to 10%).

Of the 451 total patients in the Safety Population for Study BGB A317_001, 203 (45.0%) experienced at least 1 grade 3 or higher TEAE. The most commonly occurring grade 3 or higher TEAEs (≥ 2%; 9 or more patients overall incidence) were pneumonia (22 patients, 4.9%), anemia (18 patients, 3.2%), and hypokalemia (9 patients, 2.0%).
irTEAEs and Deaths
Immune-related TEAEs ("irTEAEs") of any grade were reported in approximately 47% of patients across the monotherapy studies but were primarily low grade (9.5% ≥ grade 3). These irTEAEs have well-established algorithms for treatment and are considered manageable.

Across the monotherapy studies, the rate of treatment emergent serious AEs, or TESAEs, was 33% in patients with SD. The PRs include three PRsa variety of different disease characteristics. TESAEs considered to be related to treatment with tislelizumab were notably lower, at 9.6%.
There have been some deaths reported across the monotherapy studies with clinical data available, of which <1% of the total patient population were considered related to study drug. No new safety signals were observed since the last report as of February 29, 2020. In our clinical studies to date, the safety profile of tislelizumab has been consistent with that of molecules in nine renal cell carcinoma patients; threethe same class.

Clinical Development Plan
Tislelizumab was approved on December 26, 2019 by the NMPA for use in six urothelial cancer patients; two in four gastric cancer patients; two in two Merkel cell carcinoma patients; one in four nasopharyngeal patients; one in one penis squamous cell carcinoma patient; one in one duodenal carcinoma patient; two in two MSI-h patients, one with colorectal cancer (among a total of 13 colorectal cancer patients), and one with pancreatic cancer (among a total of two pancreatic cancer patients).



BGB-A317 Phase 1 Trial: Best Response in Target Lesion in Phase 1 Dose Escalation


BGB-A317 Phase 1 Trial: Change in Target Lesion from Baseline in Phase 1 Dose Escalation

        FourcHL patients who discontinued treatment beforehave received at least two prior therapies. We plan to launch the product in China in the first tumor imaging assessment duequarter of 2020. We expect to symptomatic deterioration (three cases)receive approval for a second indication in R/R UBC in 2020. If we receive conditional approval instead of full approval, we will be required to conduct one or grade 2 infusion reaction (one case) were not evaluablemore confirmatory studies after such conditional approvals. We also expect to submit for efficacy. Oneapproval in China for tislelizumab for the treatment of seven patients with mesothelioma discontinued therapy dueNSCLC, HCC, GC, and ESCC based on our China trials and, where appropriate, our global studies.

We are running a broad development program for tislelizumab, including 15 registration or registration-enabling clinical trials. These include global pivotal trials in Asia-prevalent cancers, NSCLC, HCC, GC, and ESCC, which are intended to treatment-related gradesupport regulatory submissions globally and in China. We have initiated pivotal or Phase 3 pneumonitis priortrials to obtaining confirmation of an initial PR. Additionally, two of 23evaluate tislelizumab as a potential second- or third-line treatment compared to docetaxel in patients with ovarianNSCLC; two Phase 3 trials evaluating tislelizumab plus chemotherapy versus chemotherapy in squamous and non-squamous histology NSCLC; and a Phase 3 trial in 1L SCLC evaluating tislelizumab plus chemotherapy versus chemotherapy. In 2020, we expect to complete enrollment in the third line versus docetaxel study, and we expect to report top-line data from the squamous and non-squamous histology Phase 3 trials. In liver cancer and onewe have ongoing studies investigating use of fivetislelizumab as a potential first-line treatment compared to sorafenib in patients with cervical cancer had significant tumor shrinkage qualifying forHCC and in second- or third-line HCC used as a PRmonotherapy in one imaging assessment but not confirmeda single arm pivotal Phase 2 study. We expect to have regulatory discussions with the relevant authorities regarding the second -or third-line monotherapy HCC study in the subsequent assessment due to disease progression.


        Additional tumor types enrolled in the study include endometrial, esophageal, gallbladder, breast, and thyroid cancers, cholangiocarcinoma, sarcoma, glioblastoma, hepatocellular, anal squamous cell, cutaneous squamous cell, adrenocorticoid, and adenoid cystic carcinomas, adenocarcinoma of mandible, and undifferentiated adenocarcinoma from teratoma, with one to five patients each.

        To date,2020. In GC we have two internal combination clinical trials ongoing. In February 2016, we initiated a Phase 1 clinical trialstudy ongoing that is investigating the use of BGB-290tislelizumab as a potential first-line treatment in combination with BGB-A317. The dose escalation portion of the study is currently enrolling subjectsplatinum and fluoropyrimidine-based chemotherapy. Finally, in ESCC we have several studies ongoing, including as a potential second-line treatment compared to investigator-chosen chemotherapy in patients with TNBC, ovarian cancer, fallopian tube cancer, peritoneal cancer, SCLC, and tumors likely to have DNA damage repair deficiencies susceptible to PARP inhibition or likely to respond toESCC, as a PD-1 blockade. In June 2016, we initiated a Phase 1 clinical trial with BGB-3111potential first-line treatment in advanced ESCC patients in combination with BGB-A317platinum and fluoropyrimidine-based chemotherapy, and most recently as a potential treatment in localized ESCC evaluating tislelizumab plus chemoradiotherapy versus chemoradiotherapy alone. We expect to complete enrollment in the second-line study comparing tislelizumab to investigator-chosen chemotherapy in the first half of 2020.

We are also testing tislelizumab in registration-enabling studies in UC, MSI-high or dMMR solid tumors and NPC. We have initiated two studies in UC, including a pivotal Phase 2 in second-line UC using tislelizumab as monotherapy, and a Phase 3 in first line UC comparing tislelizumab plus chemotherapy versus chemotherapy alone; a pivotal Phase 2 study in MSI-high or dMMR solid tumors using tislelizumab as monotherapy; and a Phase 3 in first line NPC evaluating tislelizumab plus chemotherapy versus chemotherapy alone.
We have also recently initiated a global Phase 2 trial in patients with R/R mature T- and NK-cell lymphomas.
Pamiparib (BGB-290), an inhibitor of PARP1 and PARP2
Pamiparib is an investigational, selective small molecule inhibitor of poly ADP-ribose polymerase 1 ("PARP1") and PARP2 enzymes that is being evaluated as a potential monotherapy and in combinations for the treatment of various B-cell malignancies.

        We have also initiated a Phase 1 open-label, multi-center trial with BGB-A317 in China in December 2016. The Phase 1 open-label, multi-center study of BGB-A317 is designed to investigate the safety, tolerability, pharmacokinetics, and preliminary antitumor activity of BGB-A317 in Chinese patients with advanced solid tumors.

        We plan to advance BGB-A317 into late-stage development. In addition, we plan to present the data from the dose-expansion phase of our clinical trial at a medical conference in 2017. We also plan to present data from our combination trials in 2017.

BGB-290, PARP Inhibitor

BGB-290 is a molecularly targeted, orally available, potent and highly selective inhibitor of PARP1 and PARP2. We are currently developing BGB-290 as a monotherapy and in combination with other therapies for the treatment of homologous recombination deficient cancers, which are cancers that contain abnormalities in their DNA molecule repair mechanisms, making these cancers particularly sensitive to PARP inhibitors. We believe BGB-290that pamiparib has the potential to be differentiated from other PARP inhibitors in termsbecause of its brain penetration, greater selectivity, strong DNA-trapping activity, and good oral bioavailability.

        We have completed the dose-escalation phase of our clinical trialbioavailability demonstrated in Australia and are conducting the dose-expansion phase of our clinical trial. We have dosed over 110 patients with BGB-290 in monotherapy and combination trials as of March 20, 2017. Initial analysis of data from this trial has shown BGB-290 to be well-tolerated. Proof-of-concept has also been established, with anti-tumor activity seen starting at the lowest tested dose and data suggestive of a wide therapeutic window.

preclinical models.

Mechanism of Action

PARP family members PARP1 and PARP2 are involved in DNA replication and transcriptional regulation and play essential roles in cell survival in response to DNA damage. PARP1 and PARP2 are key base-excision-repair proteins that function as DNA damage sensors by binding rapidly to the site of damaged DNA and modulating a variety of proteins in DNA repair processes. Inhibition of PARPs prevents the repair of common single-strand DNA breaks, which leads to formation of double-strand breaks during DNA replication. Double-strand DNA breaks in normal cells are repaired by homologous recombination, and normal cells are relatively tolerant of PARP inhibition. On the other hand, cancer cells with mutations in breast cancer susceptibility gene, or BRCA1/2 genes, which are key players in homologous recombination, are highly sensitive to PARP inhibition, ainhibition. This phenomenon is called "synthetic lethality" that“synthetic lethality” and is the

foundation of the therapeutic utility of PARP inhibitors as a monotherapy for BRCA mutant cancers. In addition to hereditary BRCA1/2 mutations, the synthetic lethallethality concept has been broadened to include sporadic tumors that display homologous recombination deficiency or HRD,("HRD"), a gene expression profile that resembles that of a BRCA deficient tumor. HRD can stem from somatic mutation of BRCA1/2, epigenetic silencing of BRCA genes or genetic or epigenetic loss of function of other genes in homologous recombination DNA damage repair pathways. Recent third-partyThird-party clinical studies have published results demonstrating that sensitivity to platinum-based chemotherapies confers sensitivity to

inhibition.

Another potential therapeutic utility of PARP inhibitors is rationalin combination therapy.therapy, which has strong scientific rational. PARP proteins are key factors in DNA repair pathways, in particular, base-excision-repair, which is critical for the repair of DNA lesions caused by some chemotherapeutic agents and by radiation. PARP inhibitors are hypothesized to potentiate cytotoxicity of DNA-alkylating agents such as platinum compounds, temozolomide and ionizing radiation, and may be used in combination with these agents in treating various cancers.
PARP inhibitors are also considered good potential combination partners with checkpoint inhibitors in part due to increased mutations in tumor cells as a result of the blockade of DNA repair by PARP inhibitors as a higher mutational load in cancers has been shown in clinical studies to correlate with improved response to checkpoint inhibitors.

In addition, preclinical data suggest that BRCA mutant tumors which are sensitive to PARP inhibition are likely to be immunogenic and responsive to PD-1 or PD-L1 antibodies.

Market Opportunity

and Competition

We believe that the market opportunity for PARP inhibitors is large and expanding in various tumor histology, settings and patient segments. Many tumor types have been shown to be responsive to PARP inhibitors, including ovarian cancer,OC, breast cancer, prostate cancer, SCLC, and gastric cancer.GC. PARP inhibitors have also been exploreddemonstrated encouraging activity both in settings beyond late lines with encouraging results, suchR/R patients as well as in the maintenance setting. Clinical trials have also shown thatIn the United States, in 2019 there were approximately 22,530 new cases of OC, 271,270 new cases of breast cancer, 174,650 new cases of prostate cancer, and 27,510 new cases of GC, according to the U.S. National Cancer Institute's SEER online database. In China, each year there are approximately 52,000 new cases of OC, 272,000 new cases of breast cancer, 60,000 new cases of prostate cancer, and 680,000 new cases of GC according to Chen et al. 2016.
A number of PARP inhibitors are active beyondhave been approved by the initial populationFDA. These include AstraZeneca’s LYNPARZA® (olaparib), Clovis Oncology’s RUBRACA® (rucaparib), GlaxoSmithKline / Tesaro’s ZEJULA® (niraparib), and Pfizer’s TALZENNA® (talazoparib). AbbVie’s veliparib is in late-stage development. In 2019, global sales of patients withBRCA mutations.the PARP class exceeded $1.5 billion according to company reports. In ovarian cancerChina, AstraZeneca received approval for olaparib in August 2018 under priority review that utilized international multi-center data. Zai Labs obtained the development and other cancers, there is growing understandingcommercial rights for niraparib in China, and increasing clinical data indicating that multiple DNA repair defects or HRD, other thanBRCA mutations could renderits NDA to the tumor cell to be susceptible to PARP inhibition. Collectively, we believe the addressable patient population for PARP inhibitors is fast expanding.

Potential Advantages of BGB-290

        BGB-290 is a highly potent and selective PARP inhibitor with favorable oral bioavailability. We believe BGB-290 has the potential to be differentiated fromNMPA was approved on December 30, 2019. There are other PARP inhibitors being developed by domestic Chinese companies, including fluzoparib from Hengrui and Hansoh. Fluzoparib was submitted to the NMPA in terms of brain penetration, selectivity, DNA-trapping activity, and oral bioavailability.

    Brain penetration.  BGB-290 has shown significant brain penetration in preclinical models. The brain/plasma ratio in mice after oral dosing of 10 mg/kg BGB-290 was approximately 18%. We believe the only other PARP inhibitor currently in development that has shown significant brain penetration is veliparib, which appears to be significantly less potent compared to other PARP inhibitors and has minimal DNA-trapping activity. BGB-290 has demonstrated strong synergistic anti-tumor effects with temozolomide in treating intracranially implanted glioblastoma multiforme, consistent with its ability to cross the blood-brain barrier.

    Greater selectivity potentially leading to improved safety and tolerability.  BGB-290 is a highly active and selective PARP1 and PARP2 inhibitor in biochemical and cellular assays. Enhanced selectivity could potentially translate into a better safety and tolerability profile over existing PARP inhibitors. We believe a favorable safety and tolerability profile could be particularly advantageous for the combined use of BGB-290 with immune checkpoint inhibitors or chemotherapeutic agents.

    Strong DNA-trapping activity.  PARP inhibitors are reported to trap PARP protein at damaged DNA sites, creating more cytotoxic DNA lesions. The potency of DNA-trapping for PARP inhibitors is shown to be better correlated with tumor cell growth-inhibition than inhibition of PARP enzyme activity. BGB-290 has demonstrated potent activity across multiple assays: DNA-trapping, enzymatic and cellular inhibition of PARP and tumor cell growth inhibition.

    Good oral bioavailability.  In preclinical animal models, BGB-290 demonstrated bioavailability of 71–76% in animal studies. In the ongoing dose-escalation phase of our clinical trial, we observed a linear and dose-dependent pharmacokinetic profile for BGB-290 with approximately two-fold accumulation at steady state.

Summary of Clinical Results

        As of March 20, 2017, we have dosed over 110 patients with BGB-290 in either monotherapy or combination trials.

We have completed the dose-escalation phase and are evaluating BGB-290multiple ongoing studies in the ongoing dose-expansion phase of our clinical trial in Australia.

        At the 2015 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics, we presented clinical data from our Phase 1 clinical trial. As of June 30, 2015, 29 relapsed or refractory solid tumor patients were enrolled in seven cohorts receiving monotherapy BGB-290 in doses ranging from 2.5 mg BIDindications known to 80 mg BID. Initial analysis of data from this trial suggests that BGB-290 is well-tolerated. Few AEs of myelosuppression, no liver toxicity signal, and few drug-related grade 3/4 AEs were observed in the dose-escalation phase. The most common drug-related AEs were grade 1 and 2 nausea (38%) and fatigue (28%). Drug-related grade 3/4 AEs include one each (3%) of neutropenia, anemia, hypophosphatemia and hypokalemia, all grade 3. As of January 19, 2016, drug-related SAEs reported by investigators were three cases of grade 3 anemia and one case of shortness of breath.

BGB-290 Phase 1 Trial: Best Response in Target Lesion in Ovarian Cancer Patients in Phase 1 Dose Escalation



BGB-290 Phase 1 Trial: Treatment Response and Duration by Dose and by Tumor Types in Phase 1 Dose Escalation

        In February 2016, we initiated a Phase 1 clinical trial of BGB-290 in combination with BGB-A317. The dose-escalation phase of the trial is currently enrolling subjects with TNBC, ovarian cancer, fallopian tube cancer, peritoneal cancer, SCLC, and tumors likely to have DNA damage repair deficiencies susceptible to PARP inhibition or likely to respond to a PD-1 blockade. The dose-expansion phase will include patients with BRCA 1/2-mutations or HRDs who have TNBC, metastatic castration-resistant prostate cancer, pancreatic adenocarcinoma, and platinum-sensitive ovarian, fallopian tube, and primary peritoneal cancers, as well as patients with platinum-sensitive urothelial bladder cancer, pancreatic adenocarcinoma, SCLC, and gastric or gastroesophageal junction cancers. Key objectives in the trial include assessing safety, and tolerability, maximum tolerated dose recommended Phase 2 dose, pharmacokinetics,(MTD), and preliminary anti-tumor activity of the BGB-A317combination in patients with locally advanced and BGB-290 combination.

        In December 2016,metastatic tumors. Patients received full dose pamiparib in combination with escalating doses of TMZ, administered in both pulse and continuous dosing schedules. The recommended Phase 2 dose and schedule of the combination was determined to be 60 mg of pamiparib taken orally BID for 28 days, with TMZ at 60 mg orally QD during days one through seven. Data were presented from three disease cohorts: prostate, extensive-stage SCLC, and GC. The ORR and CR rates from these cohorts were 19% and 0%, 32% and 5%, and 0% and 0%, respectively. Median follow-up time in the SCLC and gastric cohorts was four months in each cohort.

At the 2019 ESMO, we also initiatedreported results from a multi-center, open-label Phase 1 open-label, multi-center1a/1b trial with BGB-290(NCT02361723) of pamiparib being conducted in China. The Phase 1 study is designed to investigate the safety, pharmacokinetics, and antitumor activity of BGB-290Australia in Chinese patients with advanced solid tumorstumors. The Phase 1a dose-escalation and to determinedose-finding component identified the recommended Phase 2 dose to be 60 mg orally BID. The ongoing Phase 1b trial consists of a component to

disease-specific dose-expansion cohorts, and a component investigating the effects of food on the pharmacokinetic profile of a single dose. Data from 58 patients in the OC cohort showed an ORR of 40% and a CR rate of 7%.

Clinical Development Plan
Gastric Cancer
We are in the process of converting from Phase 3 to Phase 2 the clinical trial of our PARP inhibitor pamiparib versus placebo as maintenance therapy in patients with inoperable locally advanced or metastatic GC who have responded to platinum-based first line chemotherapy (NCT03427814, also known as the BGB-290-303 trial). The trial has enrolled approximately 120 patients globally since it commenced in July 2018, and the enrollment has been slower than expected. The reason for this change was not due to safety or efficacy issues. We plan to advance BGB-290 into late-stage development.evaluate data from the Phase 2 trial to assess the potential of pamiparib in this indication and the potential next steps of development as a monotherapy or in combination with other therapies.
Our clinical development program includes a Phase 3 trial as a maintenance therapy in patients with platinum-sensitive recurrent OC (NCT03519230), a pivotal Phase 2 study in third line BRCA mutated OC (NCT03333915), a Phase 2 trial in BRCA mutated HER2-negative breast cancer (NCT03575065), and a Phase 2 trial in HRD- metastatic prostate cancer (NCT03712930).
We plan to discuss our data in OC with regulatory authorities and potentially submit an NDA in China for use of pamiparib in OC in 2020. We expect to announce top-line results from our pivotal Phase 2 germline BRCA ("gBRCA")-mutated OC as well as data from our Phase 3 maintenance study in patients with platinum-sensitive recurrent OC. In addition, we plan to present the data from the monotherapy trial of BGB-290 at a medical conference in 2017. We also planexpect to present data from the OC cohort of the global Phase 1 study and data from the Phase 1 study investigating pamiparib in combination trialwith tislelizumab in 2017.

Lifirafenib (BGB-283) and BGB-3245, Inhibitors of RAF

BGB-283, RAF Dimer Inhibitor

BGB-283

Lifirafenib is aan investigational novel small molecule inhibitor of both thewith RAF monomer and dimer forms of the RAF kinase.inhibition activities. Lifirafenib has shown antitumor activities in preclinical models and in cancer patients with tumors harboring BRAF V600E mutations, non-V600E BRAF mutations or KRAS/NRAS mutations. We are currentlyhave been developing BGB-283lifirafenib for the treatment of cancers with aberrations in the mitogen-activated protein kinase or MAPK,("MAPK"), pathway, including BRAF gene mutations and KRAS/NRAS gene mutations where first generation BRAF inhibitors are not effective. The MAPK pathway is a chainconsists of proteins in the cell that communicatestransmit a signal from a receptor on the surface of the cell to the DNA in the nucleus of the cell. This pathway plays an essential role in regulating cell proliferation and survival. We intendbelieve that lifirafenib as monotherapy or in combination with other agents may have potential for treating various malignancies, such as melanoma, NSCLC, and endometrial cancer.
Currently approved BRAF inhibitors include Roche’s ZELBORAF® (vemurafenib), Novartis’ TAFINLAR® (dabrafenib) and Array BioPharma's BRAFTOVI® (encorafenib). The combination of BRAF and MEK inhibitors is approved in patients with BRAF V600E/K mutation-positive metastatic melanoma, such as Novartis’ dabrafenib and MEKINIST® (trametinib), Genentech’s vemurafenib and COTELLIC® (cobimetinib), and Array Biopharma’s encorafenib and MEKTOVI® (binimetinib). We are aware of several other BRAF inhibitors in clinical development, such as Roche’s belvarafenib and Novartis’ LXH254.
In September 2018, BeiGene and SpringWorks Therapeutics, Inc. ("SpringWorks") announced a global clinical collaboration agreement to evaluate the safety, tolerability, and preliminary efficacy of combining lifirafenib and SpringWorks' investigational MEK inhibitor, PD-0325901, in patients with advanced solid tumors. Under the collaboration, the parties began a Phase 1b clinical trial in the third quarter of 2019 to evaluate this combination in patients with advanced or refractory solid tumors that harbor RAS mutations, RAF mutations, and other MAPK pathway aberrations.
In June 2019, we and SpringWorks announced the formation of MapKure, LLC to develop BGB-283 to treat various malignancies, including melanoma, colorectal cancer, NSCLC, endometrial cancer, ovarian cancer, pancreatic cancer and papillary thyroid carcinoma. Currently approved first-generation BRAF inhibitors, vemurafenib and dabrafenib, are only active against the BRAF monomer. BGB-283 inhibits not only the monomer but also the dimer forms of BRAF. We believe BGB-283 has the potential to beBGB-3245, an investigational, selective next-generation RAF kinase inhibitor discovered by BeiGene scientists. MapKure recently initiated a first-in-class RAF dimer inhibitor globally.

        As of March 20, 2017, we have dosed over 170 patients with BGB-283. In June 2015, we completed the dose-escalation phase of our multi-center, open-label Phase 1 clinical trial (NCT04249843) in patients with advanced or refractory tumors harboring specific v-RAF murine sarcoma viral oncogene homolog B (B-RAF) genetic mutations.

Sitravatinib (MGCD-0516), a Multi-Kinase Inhibitor
In January 2018, we entered into an exclusive license agreement with Mirati Therapeutics, Inc. ("Mirati") for the development, manufacturing and commercialization of Mirati’s sitravatinib in Asia (excluding Japan and certain other countries), Australia and New Zealand. Sitravatinib is an investigational spectrum-selective kinase inhibitor, which potently inhibits receptor tyrosine kinases, including RET, TAM family receptors (TYRO3, Axl, MER), and split family receptors

(VEGFR2, KIT). Sitravatinib is being evaluated by Mirati in multiple clinical trials to treat patients who are refractory to prior immune checkpoint inhibitor therapy, including a potentially registration-enabling Phase 3 trial of sitravatinib in NSCLC initiated in the second quarter of 2019. Sitravatinib is also being evaluated as a single agent in patients with NSCLC, melanoma and other solid tumor types whose tumors harbor specific genetic alterations in the CBL protein. In recent data readouts by Mirati, sitravatinib has demonstrated durable responses in lung cancer patients who progressed after treatment with checkpoint inhibitors. We are currently conducting the multi-arm dose-expansion phase of thebegan a Phase 1 clinical trialstudy (NCT03666143) of sitravatinib in combination with tislelizumab in various solid tumors in Australia and New ZealandChina in the third quarter of 2018, and in April 2016 completed the enrollment for the dose-expansion phasesecond quarter of our clinical2019 we initiated a second study, a Phase 1/2 (NCT03941873) trial, for the treatment of solid tumorscombining sitravatinib with BRAF mutations and/tislelizumab, this one focused on HCC or aberrations in the MAPK pathway, including melanoma, thyroid cancer, colorectal cancer, NSCLC and other non-V600E BRAF mutated cancers, and KRAS/NRAS mutated endometrial cancer, colorectal cancer, NSCLC and other KRAS/NRAS mutated cancers.

Mechanism of Action

        The MAPK pathway isgastroesophageal junction cancer.

BGB-A333, a chain of proteins that communicates a signal from a receptor on the surface of a cell to the DNA in the nucleus of the cell. The pathway includes a small G protein (RAS) and three protein kinases (RAF, MEK, and ERK). A kinasePD-L1 Inhibitor
BGB-A333 is an enzyme that catalyzesinvestigational humanized IgG1-variant monoclonal antibody against PD-L1, the transferligand of a phosphate group from a donor moleculePD-1. We intend to an acceptor. This process often actsdevelop BGB-A333 either as an "on" or "off" switch to regulate cellular signaling. The MAPK pathway plays an essential role in regulating cell proliferation and survival. Activation of the RAS-RAF-MEK-ERK kinase cascade by external stimuli transduces signals from the plasma membrane into the cell nucleus to control gene expression and determine cell fate. Aberrant activation of the MAPK signal transduction pathway is frequently found in different types of cancers, contributing to increased cell division, suppressed apoptosis, and enhanced cell motility and invasion. In many cancers, a defect in the MAPK pathway leads to uncontrolled tumor growth. The two key components of the MAPK pathway, BRAF and RAS, are two of the most frequently mutated genes in human cancers. BRAF is one of the three kinases that belong to the RAF kinase family. There are three members: ARAF, BRAF and CRAF. BRAF is the most frequently mutated oncogene in this kinase superfamily. Mutated BRAF and RAS lead to activation of the MAPK pathway and promote tumor development and growth. Functions of BRAF in the MAPK pathway are key to cell proliferation and survival. Mutations that lead to activation of BRAF promote cell transformation and proliferation and thus positively correlate with tumor development and growth. The most frequent BRAF mutation, BRAF V600E, causes constitutive activation of the kinase as well as insensitivity to negative feedback mechanisms. The mutated BRAF signals as a monomer, independent of upstream growth stimuli. It has been found that RAF kinases can homo- and heterodimerize and form homodimer or heterodimer of RAF proteins. Dimerization has been reported to be one of the key mechanisms of resistance to first-generation BRAF inhibitors, such as vemurafenib and dabrafenib. The three most common molecular mechanisms of acquired resistance of BRAF V600E melanomas to RAF inhibitors—NRAS mutation, splicing of BRAF V600E that produce a truncated BRAF kinase, and BRAF V600E overexpression due to gene amplification—all result in dimerization of BRAF V600E. First-generation BRAF inhibitors only inhibit the BRAF V600E monomer form at physiologically meaningful concentrations. In contrast, BGB-283 has been shown to inhibit both BRAF V600E monomer and RAF dimer in BRAF inhibitor sensitive and resistant melanoma cell


models, which is involved in signaling downstream from RAS. We believe this feature of BGB-283 may help to address the drug resistance issues in BRAF mutated tumors and further expand its utility into RAS mutated patient populations.

Market Opportunity

        We believe BGB-283 has applications in both BRAF mutated cancers and RAS, including KRAS and NRAS, mutated cancers. The oncogenic BRAF V600E mutation was detected in approximately 8% of all human solid tumors, including approximately 45% of papillary thyroid cancers. Mutations in any one of the three RAS genes, HRAS, NRAS or KRAS, are among the most common events in human tumorigenesis. KRAS mutations are detected prominently in colorectal cancer, NSCLC and pancreatic cancer. Additionally, notable KRAS or NRAS mutation rates have been reported in melanoma, ovarian cancer, endometrial cancer, bladder cancer, biliary cancer, thyroid cancer, leukemia and multiple myeloma. The first-generation FDA-approved BRAF inhibitors have limited activity outside of melanoma, NSCLC and thyroid cancers. In addition, these first-generation BRAF inhibitors do not exhibit activity against KRAS and NRAS mutations.

Potential Advantages of BGB-283

        BGB-283 is a novel inhibitor of RAF, in both monomeric and dimeric forms. BGB-283 has demonstrated potent and reversible inhibitory activities against RAF family kinases, including wild-type ARAF, BRAF, CRAF and BRAF V600E, in biochemical assays. In addition, BGB-283 has shown potent inhibitory activity against EGFR in biochemical assays using EGFR kinases, cancer cell lines, and xenograft models. In BRAF wild-type cells that harbor the KRAS mutations, treatment with BGB-283 resulted in much reduced up-regulation of pERK, a phosphorylated form of ERK, compared with vemurafenib in cancer cell models.

        In preclinical testing, BGB-283 also retained inhibitory activity in vemurafenib-resistant BRAF splicing isoform p61-BRAF V600E. Data generated in preclinical studies using biochemical, cell-based and animal studies suggest that BGB-283 could offer significant patient benefit in inhibiting tumors with aberrations in the RAF MAPK/ERK pathway, including BRAF mutations and KRAS/NRAS mutations as either monotherapy or in combination with other cancer therapies.

        We believe BGB-283 has the potentialtherapies, such as tislelizumab, to be differentiated fromtreat various cancers and potentially other drug candidatesareas of unmet need. BGB-A333 is currently under development and from approved first-generation BRAF inhibitors due to the following:


Summary of Clinical Results

        Initial analysis of data from these trials suggests that BGB-283 is well-tolerated with a favorable safety profile. We presented initial clinical data from our Phase 1 clinical trial (NCT03379259) in Australia to assess the safety and antitumor effect of BGB-283BGB-A333 alone and in combination with tislelizumab in patients with BRAF or KRAS/NRAS-mutated cancers at the 2016 American Association for Cancer Research annual conference. As of January 31, 2016, the data cutoff date, among 31 advanced solid tumor patients,tumors.

BGB-A425, a TIM-3 Inhibitor
BGB-A425 is an investigational humanized IgG1-variant monoclonal antibody against T-cell immunoglobulin and mucin-domain containing-3 ("TIM-3"). We began a Phase 1/2 trial (NCT03744468) of BGB-A433 in combination with tislelizumab in various solid tumors in the most frequent treatment-related adverse events, or TRAE, were fatigue (52%), thrombocytopenia (39%), decreased appetite (39%), hand-foot syndrome (35%), dermatitis acneiform (32%) and hypertension (32%). The most frequent treatment-related grade 3/4 AEs included thrombocytopenia (13%), fatigue (10%) and liver enzyme elevation (10%).

fourth quarter of 2018.

BGB-A1217, a TIGIT Inhibitor
BGB-A1217 is an investigational humanized IgG1-variant monoclonal antibody directed against TIGIT. We have achieved proof-of-conceptinitiated patient enrollment in a rangePhase 1a/1b trial (NCT04047862) in Australia investigating the safety, tolerability, pharmacokinetics, and preliminary antitumor activity of cancers including thoseBGB-A1217 in combination with KRAS and BRAF mutations. At the time of the data cutoff, among 29 patients enrolled in the dose-escalation phase of the trial evaluable for efficacy, one melanoma patient with BRAF V600E mutation had a CR, one endometrial cancer patient with KRAS mutation and one thyroid cancer patient with BRAF V600E mutation had a PR, and 15 patients had an SD, including one NSCLC patient with KRAS mutation with a transient PR or durable SD. As of January 31, 2016, 15 patients had remained on treatment for over six months, and the patient with CR had ongoing treatment for 342 days, and the two patients with PR had received treatment for 455 days and 574+ days (ongoing), respectively. When assessed by underlying mutations, of six evaluable patients with the BRAF V600E mutation, there was one CR, one PR and four SDs. Of three evaluable patients with BRAF non-V600E mutation, there were two SDs. Of 20 evaluable patients with KRAS/NRAS mutations, there was one confirmed PR and nine SDs.

        We have also initiated a dose-escalation trial in China. The goal of the study is to determine dose, exposure, safety and tolerability, and efficacy. We observed more frequent grade 3/4 thrombocytopenia in the China trial (seven out of 24 patients) compared to the Australia and New Zealand trial (eight out of 105 patients).

        We expect to present data from the Phase 1 dose-expansion study of BGB-283tislelizumab in patients with BRAF or KRAS/NRAS mutatedadvanced solid tumorstumors.

BGB-11417, a Small Molecule Bcl-2 Inhibitor
BGB-11417 is a small molecule Bcl-2 inhibitor. We have completed preclinical and investigational new drug (IND) -enabling studies of BGB-11417, which demonstrated potent activity and high selectivity against the pro-apoptotic protein Bcl-2. We have initiated study start-up for a Phase 1 trial (NCT04277637) in Australia and the United States to investigate the safety, tolerability, pharmacokinetics, and preliminary antitumor activity of BGB-11417 in patients with mature B-cell malignancies.
BGB-A445, an oral presentation on April 2 duringOX40 Agonist Antibody
BGB-A445 is an agonistic antibody directed to the OX40 antigen. We have initiated a Clinical Trials Plenary Session at the 2017 American Association for Cancer Research Annual Meeting.

        In March 2017, we regained the worldwide rights to BGB-283 after Merck KGaA, Darmstadt Germany informed us that it will not exercise the Continuation OptionPhase 1 trial (NCT04215978) of our OX40 antibody in its former exclusive license to commercialize and manufacture BGB-283 outside of China.

Our Preclinical Programs

        Our

We have a proprietary cancer biology platform that has also allowed us to develop our clinical-stage drug candidates and several additional preclinical-stage drug candidates in potentially important targeted areas. These currently consist of targeted therapies and immuno-oncology agents includingagents. We have initiated first-in-human studies for two drug candidates and have initiated study start-up activities for a PD-L1 monoclonal antibody, an additional RAF dimer inhibitor,third, BGB-11417, a TIM-3 cell surface protein monoclonal antibody, and a BTK inhibitor for non-oncology indications.small molecule Bcl-2 inhibitor. We anticipate advancing one or more of our preclinical assetsdrug candidates into the clinic in the next 12 months. We believe we have the opportunity to combine our PD-1 monoclonal antibodytislelizumab with other clinical-stage andour preclinical candidates in our pipeline portfolio to target multiple points in the cancer immunity cycle. We also may seek to develop companion diagnostics that will help identify patients thatwho are most likely to benefit from the use of our drug candidates.

Manufacturing and Supply
We manufacture our drugs and drugs candidates internally and with the help of third-party contract manufacturing organizations ("CMOs"). The manufacturing of our drugs and drug candidates is subject to extensive regulations that impose various procedural and documentation requirements governing recordkeeping, manufacturing processes and controls, personnel, quality control and quality assurance, among others. Our manufacturing facilities and the facilities of the CMOs we use to manufacture our drugs and drug candidates operate under current good manufacturing practice regulations ("GMP") conditions. GMP are regulatory requirements for the production of pharmaceuticals that will be used in humans.

Collaboration

Our Manufacturing Facilities
We have an approximately 11,000 square meter multi-functional manufacturing facility in Suzhou, China, where we produce small molecule and biologics drug candidates for clinical supply and which we plan to use for commercial supply of our small molecule drug candidates in China and potentially outside of China, if approved. This facility consists of one oral-solid-dosage production line for small molecule drug products and one pilot plant for monoclonal antibody drug substances and is aligned with Merck KGaA, Darmstadt Germany

BGB-283

        On May 24, 2013,the design criteria of the United States, EU, and China regulatory requirements. The facility has a manufacturing license, which is required for the commercial manufacture of zanubrutinib in China following NDA approval.

In addition, we formed a joint venture with Guangzhou High-Tech Zone Technology Holding Group Co., Ltd. (formerly GET), an affiliate of Guangzhou Development District, to build a commercial-scale biologics manufacturing facility in Guangzhou, China. We completed the initial phase of construction in September 2019. This facility is designed to be 100,000 square meters and have a 50,000-liter commercial scale capacity. The initial phase of the facility utilizes General Electric’s state-of-the-art KUBio™ prefabricated bio-manufacturing equipment. We have received the drug manufacturing license for drug substances and drug products for this facility and are now in the process of validating this facility for global commercial supplies. Following regulatory inspection and approval, the first commercial product to be manufactured at this facility is expected to be tislelizumab.
We also have an approximately 140 square meter manufacturing facility at our research and development location in Beijing, China, which produces preclinical and clinical trial materials for some of our small molecule drug candidates.
Contract Manufacturing Organizations
We currently rely on, and expect to continue to rely on, a limited number of third-party CMOs and CROs for the production of some drug products and drug substances and the supply of raw materials to meet the commercial, clinical, and preclinical needs of our drugs and drug candidates. We have adopted procedures to ensure that the production qualifications, facilities and processes of our third-party outsourced suppliers comply with the relevant regulatory requirements and our internal quality and operation guidelines. We select our third-party suppliers carefully by considering a number of factors, including their qualifications, relevant expertise, production capacity, geographic proximity, reputation, track record, product quality, reliability in meeting delivery schedules, and terms offered by such third-party outsourced suppliers.
We have framework agreements with most of our manufacturing service providers. For example, we entered into licensea commercial supply agreement with Catalent Pharma Solutions, LLC ("Catalent") to produce BRUKINSA at Catalent’s Kansas City, MO site for commercial and clinical supply outside of China. In addition, we entered into a commercial supply agreement with Boehringer Ingelheim Biopharmaceuticals (China) Ltd. ("Boehringer Ingelheim") for our anti-PD-1 antibody tislelizumab, which is being manufactured at Boehringer Ingelheim’s facility in Shanghai, China as part of a marketing authorization holder ("MAH") project pioneered by us and Boehringer Ingelheim. For our commercial products licensed from BMS, we rely on BMS and its contract manufacturers outside of China for the supply of those drugs. For our clinical and commercial products that are being commercialized in collaboration with Amgen, we expect to rely on Amgen and its contract manufacturers outside of China for the supply of those drugs and drug candidates.
Our agreements with Merck KGaA, Darmstadt Germany,our outsourced suppliers generally set out terms, including product quality or service details, technical standards or methods, delivery terms, agreed price and payment, and product inspection and acceptance criteria. We are generally allowed to return any products that fail to meet our quality standards. Our outsourced suppliers procure raw materials themselves. Typically, outsourced suppliers request settlement of payment within 30 days from the date of invoice. Either party may terminate the agreements by serving notice to the other party under certain circumstances.
We generally obtain raw materials for our manufacturing activities from multiple suppliers who we believe have sufficient capacity to meet our demands. Raw materials and starting materials used at our facilities in Beijing and Suzhou include active pharmaceutical ingredients custom-made by our third-party CROs and excipients, which are commercially available from well-known vendors that meet the requirements of the relevant regulatory agencies. The core raw materials to be used in manufacturing at our Guangzhou facility are expected to be genetically modified cell lines that we amendedco-developed and restatedlicensed from Boehringer Ingelheim and other third parties.
We typically order raw materials on December 10, 2013a purchase order basis and which we referdo not enter into long-term dedicated capacity or minimum supply arrangements. We pay for our purchases of raw materials on credit. Credit periods granted to respectively asus by our suppliers generally range from 30 to 60 days. Our suppliers are generally not responsible for the Ex-PRC BRAFdefects of our finished products.


Amgen Collaboration
Collaboration Agreement and PRC BRAF Agreement.
On October 1, 2015 and December 3, 2015, we further amended the Ex-PRC BRAF Agreement.31, 2019 our wholly-owned subsidiary, BeiGene Switzerland GmbH (“BeiGene Switzerland”), entered into a Collaboration Agreement with Amgen, which became effective on January 2, 2020 (the "Amgen Collaboration Agreement").

Celgene License and Supply Agreement
On July 5, 2017, we and Celgene Logistics Sàrl, a wholly-owned subsidiary of China,BMS, entered into a License and Supply Agreement, which we refer to as the Ex-PRC Territory,China License Agreement and (b) Merck KGaA, Darmstadt Germany granted us an exclusive license under certain of its intellectual property rightswhich became effective on August 31, 2017, pursuant to develop, manufacture and commercialize the Licensed BRAF Inhibitors in The People's Republic of China, which we referwere granted the right to as the PRC Territory, subjectexclusively distribute and promote BMS’s approved cancer therapies, ABRAXANE, REVLIMID and VIDAZA in China, excluding Hong Kong, Macau and Taiwan. In addition, if BMS decides to the non-compete restrictions discussed below.

        Under the Ex-PRC BRAF Agreement, Merck KGaA, Darmstadt Germany had the option to continue such agreement and obtain the exclusive commercialization rights described above in the Ex-PRC Territory, which we refer to as the Continuation Option, by notifying us of that election within 60 days following its receipt of the final reports for the last of certain pre-specified Phase 1 clinical trials that we retained the responsibility to perform. In March 2017, Merck KGaA, Darmstadt Germany informed us that it will not exercise the Continuation Option, and thus the Ex-PRC BRAF Agreement has terminated in its entirety except for certain provisions that will survive the termination.

        Further, pursuant to the PRC BRAF Agreement, Merck KGaA, Darmstadt Germany has an exclusive right of first negotiation to acquire exclusive commercialization rights under the BGB-283 BRAF program in the PRC Territory on terms to be mutually agreed in the event we seek to license our intellectual property rights tocommercialize a new oncology product through a third party therein.

        Under the Ex-PRC and PRC BRAF Agreements, in December 2013, we received $13 million in non-refundable payments. As of December 31, 2016, we have received $9 million in milestone payments. We are eligible to receive additional $14 million in payments upon the successful achievement of pre-specified clinical milestones in the PRC Territory.

        We are required to pay Merck KGaA, Darmstadt Germany a high single-digit royalty on aggregate net sales of Licensed BRAF Inhibitors inlicensed territory during the PRC Territory.

        The termfirst five years of the PRC BRAF Agreement continues unless terminated as permitted by either party. Under the PRC BRAF Agreement, Merck KGaA has the right to terminate due to our uncured breach or voluntarily upon prior written notice. Weterm, we have the right to terminate the PRC BRAF Agreement due to Merck KGaA's uncured breach or for any challenge brought against our licensed patent rights.

BGB-290

        On October 28, 2013, we entered into license agreements with Merck KGaA, Darmstadt Germany, which we refer to respectively as the Ex-PRC PARP Agreement and the PRC PARP Agreement, pursuant to which (a) we granted to Merck KGaA, Darmstadt Germany an exclusive license under certain of our intellectual property rights to develop and manufacture, and, if Merck KGaA, Darmstadt Germany exercised a continuation option, to commercialize and manufacture our compound BGB-290 and any other compound covered by the same existing patent rights with primary activity to inhibit PARP 1, 2 or 3 enzymes, or the Licensed PARP Inhibitors, in the Ex-PRC Territory, and (b) Merck KGaA, Darmstadt Germany granted us an exclusive license under certain of its intellectual property rights to develop, manufacture and commercialize the Licensed PARP Inhibitors in the PRC Territory.


On October 1, 2015, pursuant to a purchase of rights agreement, we repurchased all of Merck KGaA, Darmstadt Germany's rights under the Ex-PRC PARP Agreement, in consideration for, among other things, a one-time payment of $10 million and reduction of future milestone payments we were eligible for under the PRC PARP Agreement. In connection with that repurchase, we also agreed to provide Merck KGaA, Darmstadt Germany with global access to our clinical PARP supplies, including BGB-290, for its combination trials, during the option period.

Regulatory Framework and Structural Advantages of Being a China-Based Research and Development Organization

        We believe that basing our research and development effort in China offers important regulatory advantages that differentiate us from most multinational biopharmaceutical and biotechnology companies. These advantages include the following:


        We believe our strategy and approach is aligned with the Chinese government's policies, and we intend to continue to work with local authorities to bring innovative therapeutics to patients in China as quickly as possible.

        In August 2015, the Chinese State Council, issued a statement,Opinions on reforming the review and approval process for pharmaceutical products and medical devices that contained several potential policy changes that could benefit the pharmaceutical industry:

        In November 2015, the CFDA releasedCircular Concerning Several Policies on Drug Registration Review and Approval, or the No. 230 Circular, which further clarified the following policies potentially simplifying and accelerating the approval process of clinical trials:


        In February 2016, the CFDA released theOpinions on Priority Review and Approval for Resolving Drug Registration Applications Backlog, which further clarified the following policies potentially accelerating the approval process of certain clinical trials or drug registrations which may benefit us:

        In March 2016, the CFDA released a circular,CFDA Announcement on Reforms of Pharmaceutical Registration Classification, which outlined the re-classifications of drug applications. Under the new categorization, innovative drugs that have not been approved either in or outside China remain Category 1, while drugs approved outside China seeking marketing approval in China are now Category 5.

        The CFDA is soliciting public opinions on detailed policies regarding fast track clinical trial approval and drug registration pathway, and we expect that the CFDA review and approval process will improve over time.

Regulatory Framework for Novel Drugs in China

        The CFDA categorizes domestically-manufactured innovative drug applications as Category 1 and imported innovative drug applications as Category 3, until a recent CFDA announcement issued on March 4, 2016 which reclassifies imported drug applications into Category 5.

        Most Chinese companies' applications for innovative drugs are filed in Category 1 if the drug has not already been approved by the FDA or EMA. Most multinational pharmaceutical companies' drug registration applications are filed in Category 5.

        Under the current regulations, these two categories have distinct approval pathways as discussed below.

Domestic Innovative Drug Registration Process

        For domestically manufactured innovative drug applications, companies are required to obtain approval of a Clinical Trial Application before conducting Phase 1 clinical trials in China. The domestic innovative drug registration pathway has a fast track review and approval mechanism if the drug candidate is on a national priority list.

Imported Innovative Drug Registration Process

        For a drug that has received marketing approval in other countries, but is not yet approved in China, in order to market an imported drug in China, companies must apply for an Import Drug


License, or IDL, after the drug has received marketing approval and a Certificate of Pharmaceutical Product, or CPP, from a major foreign drug regulatory authority, such as the FDA or EMA. Compared with the domestic innovative registration process, the imported innovative drug registration process is more complex.

        The first step in the process after receipt of a CPP is to obtain approval of a Clinical Trial Application to conduct registration studies. A pharmacokinetic study in Chinese subjects is also required. Once this study is completed, the applicant must submit the clinical data package to the CFDA along with other required information for the issuance of an IDL. The IDL registration process together with clinical trials have typically taken more than five years from the receipt of foreign marketing approval.

        Currently, the most common strategy for multinational companies is using multi-regional clinical trial, or MRCT, data to support IDL approval. Companies can apply to conduct these MRCTs prior to receiving global regulatory approval, with China as a subset within a broader MRCT. However, these MRCTs are often not designed in a way that accounts for the unique characteristics of the Chinese patient population and local standards of care. If the MRCT data does not meet the CFDA's registration requirements, the company may be required to conduct additional local clinical trials that can potentially delay market access in China for imported drugs by an additional three to four years.

        The Chinese State Council and the CFDA have recently issued several statements and circulars aimed at improving and accelerating the new drug approval process in general. These include the August 2015 statement issued by the Chinese State Council,Opinions on reforming the review and approval process for pharmaceutical products and medical devices ; the November 2015 CFDA No. 230 Circular,Circular Concerning Several Policies on Drug Registration Review and Approval ; February 2016 CFDA Circular,Opinions on Priority Review and Approval for Resolving Drug Registration Applications Backlog ; and the March 2016 CFDA No. 51 Circular,Announcement on Reforms of Pharmaceutical Registration Classification issued by the CFDA on March 4, 2016. In the March 4, 2016 CFDA announcement, the drugs approved outside China seeking marketing approval in China are now called Category 5. We believe these new regulatory initiatives will likely accelerate the approval process for new drugs, including those marketed in other countries but not yet in China. However, how and when this approval process will be changed is still subject to further policies to be issued by the CFDA and is currently uncertain.

Commercial Opportunities in China

        In addition to the structural and clinical advantages affordednotice to us by basing our researchunder certain circumstances.

China's Pharmaceutical Market

        China's pharmaceutical market has grown robustly and replaced Japan as the second largest pharmaceutical market in 2013, according to IMS Health. According to the IMS Market Prognosis published in March 2015, the Chinese pharmaceutical market was $109 billion in 2014, as compared to a $373 billion U.S. pharmaceutical market in 2014, and is expected to grow at a compound annual growth rate, or CAGR, of 9.3% over the next five years reaching $171 billion by 2019. The growth of the Chinese pharmaceutical market is attributable, in particular to:

        China provides an opportunity to access largely untapped clinical trial pools and develop drugs for a population for whom global standard of care therapies are not available. China has nearly a quarter of the world's cancer patient population and one third to half of cancer patients in certain tumor types are in China, such as lung, gastric, liver and esophageal cancers.


Note: * New cancer incidences estimated to increase to 19 and 25 million in 2025 and 2035, respectively. Source: Data from World Health Organization (2012)

        The oncology market in China is estimated to have grown at a CAGR of 24% in the last decade through 2014. In recent years, sales of targeted therapy drugs in retail channels have increased rapidly. Although expensive targeted therapy drugs are not included in basic national healthcare insurance and have historically had very little coverage by provincial insurance plans, the targeted therapy drug market has continued to grow rapidly despite being an out-of-pocket market. This growth is attributable to patients' needs, newly launched drugs and patient's ability to pay for drugs not covered by insurance.

Introduction of Reimbursement

        The Chinese State Council requires central and provincial authorities across the PRC to promote a medical insurance program for major illnesses. By the end by 2015, all urban and rural residents covered by basic medical insurance programs are required to be covered by the insurance program for major illnesses, according to a Chinese State Council policy issued on July 28, 2015. As a complement to basic insurance programs, this program is required to cover at least 50% of the medical cost incurred in connection with treating major illnesses and is supplemental to basic insurance programs. The Chinese State Council now requires provincial authorities to increase reimbursement rates over the next three years.

        According to the PRC Central Government's guidance issued in March 2015, each province will decide which drugs to include in its provincial major illness reimbursement lists and the percentage of reimbursement, based on local funding. For example, Zhejiang province, located in the Yangtze river delta area with a population of 55 million, announced its provincial major illness drug reimbursement list in early 2015. The list includes 31 high-priced drugs, 15 of which are targeted therapy agents for cancer, including Glivec, Ireesa, Erbitux, Herceptin, and Rituxan. Although it will take three years to establish comprehensive national coverage, the affordability of the high-priced, novel cancer agents to Chinese patients could improve significantly.


        On February 23, 2017, the Ministry of Human Resources and Social Security released the long-expected new version of the national reimbursement drug list, or NRDL. The NRDL has been expanded by 16.7%, with covered drugs increased from 2,172 in the 2009 version to 2,535, including 1,297 chemical / biological drugs (51.1% of total, vs. 1,140 in 2009) and 1,238 traditional Chinese medicines / ethnic drugs (48.9% of total, vs. 1,032 in 2009). Several targeted oncology drugs are on the list, including icotinib, dasatinib, gefitinib, and imatinib. NRDL inclusion could be a significant opportunity over the long term an improve the market penetration for the drugs being newly included.

Our Mission and Strategy

        Our mission is to become a global leader in the discovery and development of innovative, molecularly targeted and immuno-oncology drugs for the treatment of cancer. To achieve our mission, we intend to pursue the following strategies:


Intellectual Property

The proprietary nature of, and protection for, our drugs, drug candidates, and their methods of use are an important part of our strategy to develop and commercialize novel medicines, as described in more detail below. We have obtained a U.S. patentpatents and filed patent applications in the United States and other countries and regions, such as China and Europe, relating to our drugs and certain of our drugs and drug candidates, and are pursuing additional patent protection for them and for our other of our drug candidates and technologies. We also rely on trade secrets to protect aspects of our business that are not amenable to, or that we do not consider appropriate for, patent protection including our manufacturing processes.

        Our success will depend significantly on our ability to obtain and maintain patent and other proprietary protection for our product candidates and other commercially important products, technologies, inventions and know-how, as well as on our ability to defend and enforce our patents including any patent that we have or may issue from our patent applications, preserve the confidentiality of our trade secrets and operate without infringing the valid and enforceable patents and proprietary rights of other parties. We also rely on know-how, continuing technological innovation and in-licensing opportunities to develop, strengthen and support our development programs.

As of March 21, 2017,January 29, 2020, we own eightowned 25 issued U.S. patents, and eight11 issued China patents, a number of pending U.S. and China patent applications, as well asand corresponding patents and patent applications internationally. In addition, we own 13


owned pending international patent applications under the Patent Cooperation Treaty or PCT,("PCT"), which we plan to file nationally in the United States and other jurisdictions.jurisdictions, as well as additional priority PCT applications. With respect to any issued patents in the United States and Europe, we may be entitled to obtain a patent term extension to extend the patent expiration date, provided that we meet the applicable requirements for obtaining such patent term extensions. For example, in the United States, we can apply for a patent term extension of up to five years for one of the patents covering a drug product once the product is approved by the FDA. The exact duration of the extension depends on the time that we spend in clinical studies as well as getting a new drug application, or NDA, approval from the FDA.

As such, any issued patents may not protect us from generic or biosimilar competition for these applications, if any, would be expected to expire in 2037. We intend to pursue marketing exclusivity periods that are available under regulatory provisions in certain countries

BGB-A317.  We are the owner of one issued U.S. patent, one pending U.S. application, one pending PCT application, and corresponding pending patent applications in other jurisdictions directed to BGB-A317, a humanized monoclonal antibody against PD-1, and its use for the treatment of cancer. The expected expiration for the issued U.S. patent is 2033, excluding any additional term for patent term extensions. Any patent that may issue from the currently pending U.S. patent application would be expected to expire in 2033, not including any patent term adjustments. If a U.S. application is filed based on the pending PCT application, a patent issuing from the application, if any, would be expected to expire in 2037. We intend to pursue marketing exclusivity periods that are available under regulatory provisions in certain countries.

BGB-290.  We own one issued U.S. patent, one pending U.S. patent application, and two pending PCT applications directed to BGB-290, a small molecule PARP1/2 inhibitor, and its use for the treatment of cancer, including glioblastomas and breast cancer. We also own the corresponding pending patent applications in other jurisdictions. The expected expiration for the issued U.S. patent is 2031, excluding any additional term for patent term extensions. Any patent that may issue from the currently pending U.S. patent application would be expected to expire in 2031, not including any patent term adjustments. If a U.S. application is filed based on the pending PCT applications, a patent issuing from these applications, if any, would be expected to expire in 2036 and 2037. We intend to pursue marketing exclusivity periods that are available under regulatory provisions in certain countries.

BGB-283.  We own one issued U.S. patent, one pending U.S. patent application, and two pending PCT applications directed to BGB-283, a small molecule BRAF inhibitor, and its use for the treatment of cancer, including BRAF mutated cancers. We also own pending patent applications in other jurisdictions corresponding to the U.S. patent application. In addition, we plan to file nationally in the U.S. and other jurisdictions based on the pending PCT application. The expected expiration for the issued U.S. patent is 2031, excluding any additional term for patent term extensions. Any patent that may issue from the currently pending U.S. patent application would be expected to expire in 2031, not including any patent term adjustments. If a U.S. application is filed based on the pending PCT applications, a patent issuing from these applications, if any, would be expected to expire in 2036 and 2037. We intend to pursue marketing exclusivity periods that are available under regulatory provisions in certain countries.
drugs.

The term of individual patents may vary based on the countries in which they are obtained. In most countries in which we file, including the United States and China, the term of an issued patent is generally 20 years from the earliest claimed filing date of a non-provisional patent application in the applicable country. In the United States, a patent'spatent’s term may be lengthened in some cases by a patent term adjustment, which extends the term of a patent to account for administrative delays by the U.S.United States Patent and Trademark Office or USPTO,(the "USPTO"), in excess of a patent applicant'sapplicant’s own delays during the prosecution process, or may be shortened if a patent is terminally disclaimed over a commonly owned patent having an earlier expiration date. In addition, in certain instances, a patent term can be extended to recapture a portion of the term effectively lost as a result of thein obtaining FDA regulatory review period.approval. However, the restoration period cannot be longer than five years and the total patent term including the restoration period must not exceed 14 years following FDA approval.

In certain foreign jurisdictions similar extensions as compensation for regulatory delays are also available. The actual protection afforded by a patent varies on a claim by claim and country by country basis and depends upon many factors, including the type of patent, the scope of its coverage, the availability of any patent term extensions or adjustments, the availability of legal remedies in a particular country and the validity and enforceability of the patent.

        Furthermore, the patent positions of biotechnology and pharmaceutical products and processes like those we intend to develop and commercialize are generally uncertain and involve complex legal and factual questions. No consistent policy regarding the breadth of claims allowed in such patents has emerged to date in the United States. The scope of patent protection outside the United States is even more uncertain. Changes in the patent laws or in interpretations of patent laws in the United States and other countries may diminish our ability to protect our inventions, and enforce our intellectual property rights and more generally, could affect the value of intellectual property.

        Additionally, we cannot predict the breadth of claims that may be allowed or enforced in our patents or in patents owned by others. Substantial scientific and commercial research has been conducted for many years in the areas in which we have focused our development efforts, which has resulted in other parties having a number of issued patents and pending patent applications relating to such areas. Patent applications in the United States and elsewhere are generally published only after 18 months from the priority date, and the publication of discoveries in the scientific or patent literature frequently occurs substantially later than the date on which the underlying discoveries were made. Therefore, patents and patent applications relating to drugs similar to our current drug candidates and any future drugs, discoveries or technologies we might develop may have already issued or been filed, which could prohibit us from commercializing our product candidates. Specifically, we are aware of certain U.S. patents owned by Ono Pharmaceutical Co. and licensed to Bristol-Myers Squibb Co. that are relevant to our BGB-A317 drug candidate. We are also aware of a U.S. patent owned by Pharmacyclics, Inc., which was acquired by AbbVie Inc., that is relevant to our BGB-3111 drug candidate, and certain U.S. patents owned or licensed by KuDOS Pharmaceuticals, Ltd., which was acquired by AstraZeneca PLC, that are relevant to our BGB-290 drug candidate. For more information, see "Item 1A—Risk Factors—Risks Related to Our Intellectual Property."

        The biotechnology and pharmaceutical industries are characterized by extensive litigation regarding patents and other intellectual property rights. Our ability to maintain and solidify our proprietary position for our drug candidates and technology will depend on our success in obtaining effective claims and enforcing those claims once granted. We do not know whether any of the patent applications that we may file or license from others will result in the issuance of any patents. The issued patents that we own or may receive in the future, may be challenged, invalidated or circumvented, and the rights granted under any issued patents may not provide us with proprietary protection or competitive advantages against competitors with similar technology. Furthermore, our competitors may be able to independently develop and commercialize similar drugs or duplicate our technology, business model or strategy without infringing our patents. Because of the extensive time


required for clinical development and regulatory review of a drug we may develop, it is possible that, before any of our drug candidates can be commercialized, any related patent may expire or remain in force for only a short period following commercialization, thereby reducing any advantage of any such patent.

We may rely, in some circumstances, on trade secrets and unpatented know-how to protect aspects of our technology. However, trade secrets can be difficult to protect. We seek to protect our proprietary technology and processes, in part, by entering into confidentiality agreements with employees, consultants, scientific advisors and contractors and invention assignment agreements with our employees. We also seek to preserve the integrity and confidentiality of our data and trade secrets by maintaining physical security of our premises and physical and electronic security of our information technology systems. While

Additionally, we currently own a number of registered trademarks and pending trademark applications. We currently have confidenceregistered trademarks for BeiGene, our corporate logo and product names and logos in these individuals, organizationsChina, the EU and systems, agreements or security measures may be breachedother jurisdictions, and we may not have adequate remediesare seeking trademark protection for any breach. In addition,BeiGene, our trade secrets may otherwise become known or be independently discovered by competitors. To the extent that our consultants, contractors or collaborators use intellectual property owned by others in their work for us, disputes may arise as to the rights in related or resulting know-howcorporate logo, product names and inventions.

        Our commercial success will also depend in part on not infringing the proprietary rights oflogos, and other parties. The issuance of any patent by others with claims covering or related to aspects of our product candidates would require us to alter our development or commercial strategies, redesign our drug candidates or processes, obtain licenses or cease certain activities. Such licenses may not be available on reasonable commercial terms or at all, which could require us to cease development or commercialization of our product candidates. In addition, our breach of any license agreements or failure to obtain a license to proprietary rights that we may require to develop or commercialize our drug candidates would have a material adverse impact on us. If others have prepared and filed patent applicationsmarks in the United States that also claim technology to which we have filed patent applications, we may have to participate in interference, derivation or other proceedings in the USPTO to determine issues such as priority of claimed invention or validity of such patent applications as well as our own patent applications and issued patent.

        For more information on these and other risks related to intellectual property, see "Item 1A—Risk Factors—Risks Related to Our Intellectual Property."

        Additionally, we currently use a number of unregistered trademarks and are seeking trademark protection in jurisdictionscountries where available and appropriate. We currently have applications pending in China for BeiGene, and our corporate logo.

Competition

        Our industry is highly competitive and subject to rapid and significant change. While we believe that our development and commercialization experience, scientific knowledge and industry relationships provide us with competitive advantages, we face competition from pharmaceutical, medical device and biotechnology companies, including specialty pharmaceutical companies, and generic drug companies, academic institutions, government agencies and research institutions.

BGB-3111 Competition

        We are developing BGB-3111, a highly selective small molecule covalent BTK inhibitor, for a variety of B-cell malignancies, either as a monotherapy or in combination with other therapies.


        Janssen/AbbVie's ibrutinib (IMBRUVICA) is one of the currently approved drugs used for the treatment of B-cell malignancies, including patients with MCL who have received at least one prior therapy, patients with CLL, CLL patients with 17p deletion, and WM. It has also recently been approved by the FDA for the treatment of patients with relapsed/refractory MZL who require systemic therapy and have received at least one prior anti-CD20-based therapy.

        Multiple ongoing Phase 3 trials are currently being conducted for ibrutinib as a monotherapy or in combination with chemotherapeutics or target therapeutics in various B-cell malignancies, including CLL, MCL, WM, FL, DLBCL and MZL. In addition, we are aware of other BTK inhibitors in clinical development for oncology indications, including AstraZeneca's acalabrutinib (ACP-196) currently in Phase 3, Ono/Gilead's tirabrutinib in Phase 2, Sunesis' SNS-062 in Phase 1b/2, Merck KGaA, Darmstadt Germany's M7583 in Phase 1, and Zhejiang Daoming BioPharma's DTRMWXHS-12 in Phase 1.

BGB-A317 Competition

        Three anti-PD-1 or PDL1 monoclonal antibody drugs, Merck's pembrolizumab (Keytruda), Bristol-Myers Squibb's nivolumab (Opdivo), and Roche's atezolizumab (Tecentriq) have been approved by the FDA.

        A number of companies are currently conducting ongoing clinical trials involving an anti-PD-1 or anti-PD-L1. Three anti-PD-L1 antibody drugs, AstraZeneca/Celgene's durvalumab and Pfizer/Merck KGaA, Darmstadt Germany's avelumab, together with anti-PD-1 antibodies, Merck's pembrolizumab, Bristol-Myers Squibb's nivolumab and Regeneron's REGN2810, are currently engaged in a number of Phase 2/3 trials, for treatment of multiple cancers, such as NSCLC, HNSCC, bladder cancer, triple-negative breast cancer, non-Hodgkin's lymphoma and melanoma, advanced cutaneous squamous cell carcinoma. Several new anti-PD-1 antibodies have started Phase 1/2 trials, including AstraZeneca's MEDI0680, and Novartis' PDR001, Tesaro's TSR042 and Incyte / Hengrui's SHR-1210. In China, anti-PD-1 antibody SHR-1210 from Jiangsu Hengrui is in Phase 2/3 monotherapy trial in hepatocellular carcinoma and several Phase 1/2 studies in solid tumors such as melanoma as well as ongoing Phase 1/2 combination trial with apatinib for hepatocellular carcinoma and gastric cancer. Other anti-PD-1 antibodies in clinical development by a domestic company include Junshi's JS001 and Innovent Bio's IBI308 and are undergoing multiple Phase 1 studies in solid tumors in China.

        Many of our competitors have significantly greater financial, technical and human resources than we have. Mergers and acquisitions in the pharmaceutical, medical device and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Our commercial opportunity could be reduced or eliminated if our competitors develop or market products or other novel therapies that are more effective, safer or less costly than our current or future drug candidates, or obtain regulatory approval for their products more rapidly than we may obtain approval for our drug candidates. Our success will be based in part on our ability to identify, develop and manage a portfolio of drug candidates that are safer and more effective than competing products.

BGB-290 Competition

        AstraZeneca's olaparib (LYNPARZA) is approved by the FDA for treating patients with deleterious or suspected deleterious germline BRCA mutated, or gBRCAm advanced ovarian cancer who have been treated with three or more prior lines of chemotherapy or a combination of chemotherapies. It is approved by the EMA as a maintenance treatment for patients with platinum-sensitive relapsed BRCA-mutated, germline and/or somatic, high grade serous epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in CR or PR to platinum-based chemotherapy. In addition, the FDA recently approved Clovis' rucaparib (RUBRACA) for treatment of patients with


deleterious BRCA mutation, germline and/or somatic, associated advanced ovarian cancer who have been treated with two or more chemotherapies.

        There are a number of companies with ongoing clinical trials, including AstraZeneca, Abbott, Tesaro and Pfizer. AstraZeneca's olaparib has been approved in gBRCAm ovarian cancer and is currently in Phase 3 trials for treatment of gBRCAm breast cancer, gastric cancer, gBRCAm pancreatic cancer and other cancers with sBRCAm or homologous recombinant repair associated genetic mutations.

In November 2016, Tesaro submitted a NDA to the FDA for niraparib as a second-line maintenance therapy in patients with ovarian cancer. Niraparib also is currently in Phase 3 trials as a first-line maintenance treatment in patients with ovarian cancer with homologous recombination gene deficiency following response on front-line platinum-based chemotherapy and gBRCAm breast cancer. Pfizer's talazoparib is currently in Phase 3 trials for BRCAm breast cancer. Abbott's veliparib, in combination with other compound(s), is currently in Phase 3 trials for treatment of non-small-cell lung cancer, breast, ovarian cancers and glioblastoma multiforme. In China, PARP inhibitors in Phase 1 trials by domestic companies include Jiangsu Hansoh's fluzoparib and Jiangxi Qingfeng's SC10914.

BGB-283 Competition

        We are developing BGB-283 as either a monotherapy or in combination with other cancer therapies for the treatment of cancers with aberrations in the MAPK pathway including BRAF mutations and KRAS/NRAS mutations.

        Roche's vemurafenib (Zelboraf) and Novartis' dabrafenib (Tafinlar) are two of the currently approved BRAF inhibitors for treating late-stage BRAF V600E/K mutant melanoma. In addition, the combination of dabrafenib and GSK's trametinib (Mekinist), an MEK inhibitor, is approved in patients with BRAF V600E/K mutation-positive metastatic melanoma. We are aware of several other BRAF inhibitors in clinical development targeting BRAF V600E/K mutated cancers including melanoma, NSCLC, HCL and thyroid cancer. These BRAF inhibitors include Array Biopharma's encorafenib (LGX818), currently in Phase 3 trials, and Takeda's MLN-2480 (BIIB-024), Daiichi Sankyo's PLX-8394, and Roche's RG-6185, all in Phase 1 trials.

Government Regulation

Government authorities in the United States at the federal, state and local level and in other countries extensively regulate, among other things, the research and clinical development, testing, manufacture, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, post-approval monitoring and reporting, marketing, pricing and export and import of drug products,drugs such as those we are developing.developing and commercializing. Some jurisdictions also regulate the pricing of drugs. Generally, before a new drug can be marketed, considerable data demonstrating its quality, safety and efficacy must be obtained, organized into a format specific to each regulatory authority, submitted for review and approved by the regulatory authority.

        Drugs are also subject to other federal, state and local statutes and regulations. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources. Failure to comply with the applicable regulatory requirements at any time during the product development process, approval process or after approval, may subject an applicant to administrative or judicial sanctions. These sanctions could include, among other actions, the regulatory authority's refusal to approve pending applications, withdrawal of an approval, clinical holds, untitled or warning letters,


voluntary product recalls or withdrawals from the market, product seizures, total or partial suspension of production or distribution injunctions, debarment, fines, refusals of government contracts, restitution, disgorgement, or civil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect on us.

U.S. Regulation

U.S. Government Regulation and Product Approval

        Government authorities in the United States at the federal, state and local level extensively regulate, among other things, the research, development, testing, manufacture, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, marketing, export and import of drug and biological products such as those we are developing.

In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act or FDCA,("FDCA"), and its implementing regulations, and biologics under the FDCA, its implementing regulations, and the Public Health Service Act or PHSA,("PHSA"), and its implementing regulations.

Cancer therapies are sometimes characterized as first line, second line or third line, and the FDA often approves new therapies initially only for second or third-line use. When cancer is detected early enough, first line therapy is sometimes adequate to cure the cancer or prolong life without a cure. Whenever first line therapy, usually chemotherapy, hormone therapy, surgery or a combination of these, proves unsuccessful, second line therapy may be administered. Second line therapies often consist of more chemotherapy, radiation, antibody drugs, tumor targeted small molecule drugs or a combination of these. Third line therapies can include bone marrow transplantation, antibody and small molecule targeted therapies, more invasive forms of surgery and new technologies.
U.S. Drug Development Process

        The process of obtaining regulatory approvals and compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources. Failure to comply with the applicable U.S. requirements at any time during the product development process, approval process, or after approval, may subject an applicant to administrative or judicial sanctions. These sanctions could include the FDA's refusal to approve pending applications, withdrawal of an approval, a clinical hold, untitled or warning letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement or civil or criminal penalties.

The process required by the FDA before a drug or biologic may be marketed in the United States generally involves the following:

completion of preclinical laboratory tests, animal studies and formulation studies according to Good Laboratory Practices or GLP, and current Good Manufacture Practice ("GLP"), or GMP, regulations;

submission to the FDA of an INDinvestigational new drug ("IND") application, which must become effective before human clinical trials may begin;


performance of adequate and well-controlled human clinical trials according to Good Clinical Practice, or GCP, to establish the safety and efficacy of the proposed productdrug or safety, purity and potency of the proposed biologic, for itsthe intended use;

preparation and submission to the FDA of aan NDA for a drug or a Biologics License Application or BLA,("BLA") for a biologic;

a determination by the FDA within 60 days of its receipt of aan NDA or BLA to file the application for review;

satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the product, or components thereof, are produced to assess compliance with current Good Manufacturing Practices, or cGMP;

FDA audits of some clinical trial sites to ensure compliance with GCPs; and

FDA review and approval of the NDA or licensing of the BLA.

        The testing and approval process requires substantial time, effort and financial resources and we cannot be certain that any approvals for our drug candidates will be granted on a timely basis, if at all.


Once a pharmaceutical product drugcandidate is identified for development, it enters the preclinical testing stage. Preclinical tests include laboratory evaluations of product chemistry, toxicity, formulation and stability, as well as animal studies. An IND sponsor must submit the results of the preclinical tests, together with manufacturing information, analytical data and any available clinical data or literature, to the FDA as part of the IND. The sponsor must also include a protocol detailing, among other things, the objectives of the initial clinical trial, dosing procedures, subject selection and exclusion criteria, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated if the initial clinical trial lends itself to an efficacy evaluation. Some preclinical testing may continue even after the IND is submitted. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA raises concerns or questions related to athe proposed clinical trial and places the trial on a clinical hold within that 30-day time period. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. Clinical holds also may be imposed by the FDA at any time before or during clinical trials due to safety concerns or noncompliance and may be imposed on all products within a certain class of products. The FDA also can impose partial clinical holds, for example, prohibiting the initiation of clinical trials of a certain duration or for a certain dose.

All clinical trials must be conducted under the supervision of one or more qualified investigators in accordance with GCP regulations. These regulations include the requirement that all research subjects provide informed consent in writing before their participation in any clinical trial. Further, an Institutional Review Board, or IRB,institutional review board ("IRB") must review and approve the plan for any clinical trial before it commences at any institution, and the IRB must conduct continuing review and reapprove the study at least annually. An IRB considers, among other things, whether the risks to individuals participating in the clinical trial are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the information regarding the clinical trial and the consent form that must be provided to each clinical trial subject or his or her legal representative and must monitor the clinical trial until completed.

Each new clinical protocol and any amendments to the protocol must be filed with the FDA as an IND amendment and submitted to the IRBs for approval. Protocols detail, among other things,
A sponsor who wishes to conduct a clinical trial outside of the objectives ofUnited States may, but need not, obtain FDA authorization to conduct the clinical trial dosing procedures, subject selectionunder an IND. If a foreign clinical trial is not conducted under an IND, the sponsor may submit data from the clinical trial to the FDA in support of a BLA or NDA. The FDA will accept a well-designed and exclusion criteria,well-conducted foreign clinical study not conducted under an IND if the study was conducted in accordance with GCP requirements, and the parametersFDA is able to be used to monitor subject safety.

validate the data through an onsite inspection if deemed necessary.

Human clinical trials are typically conducted in three sequential phases that may overlap or be combined:

Phase 1.  The product is initially introduced into a small number of healthy human subjects or patients and tested for safety, dosage tolerance, absorption, metabolism, distribution and excretion and, if possible, to gain early evidence on effectiveness. In the case of some products for severe or life-threatening diseases, especially when the product is suspected or known to be unavoidably toxic, the initial human testing may be conducted in patients.
Phase 2.  Involves clinical trials in a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate the efficacy of the product for specific targeted diseases and to determine dosage tolerance and optimal dosage and schedule.
Phase 3.  Clinical trials are undertaken to further evaluate dosage, clinical efficacy and safety in an expanded patient population. These clinical trials are intended to evaluate the overall risk/benefit relationship of the product and provide an adequate basis for product labeling.


Phase 2.  Involves clinical trials in a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate the efficacy of the product for specific targeted diseases and to determine dosage tolerance and optimal dosage and schedule.

Phase 3.  Clinical trials are undertaken to further evaluate dosage, clinical efficacy and safety in an expanded patient population at geographically dispersed clinical trial sites. These clinical trials are intended to establish the overall risk/benefit relationship of the product and provide an adequate basis for product labelling.

We refer to our Phase 1 programprograms as dose-escalation and dose-expansion trials.

In addition, we refer to some of our Phase 2 programs as pivotal or registrational programs, where the results can be used to support regulatory approval in specific jurisdictions without the need to conduct a Phase 3 trial.

Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and safety reports must be submitted to the FDA and the investigators for serious and unexpected suspected AEs, any clinically important increase in the rate of a serious suspected adverse


reaction over that listed in the protocol or investigator'sinvestigator’s brochure, or any findings from other studies or animal orin vitro testing that suggest a significant risk in humans exposed to the product drug. The sponsor must submit an IND safety report within 15 calendar days after the sponsor determines that the information qualifies for reporting. The sponsor also must notify the FDA of any unexpected fatal or life-threatening suspected adverse reaction within seven calendar days after the sponsor's initial receipt of the information. Phase 1, Phase 2, and Phase 3 studies may not be completed successfully within any specified period, ifor at all. The FDA or the sponsor may suspend or terminate a clinical trial at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB'sIRB’s requirements or if the product has been associated with unexpected serious harm to subjects.

Concurrent with clinical trials, companies usually complete additional animal studies and must also develop additional information about the chemistry and physical characteristics of the product and finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product drug and, among other things, the manufacturer must develop methods for testing the identity, strength, quality and purity of the final product. Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate that the product drug does not undergo unacceptable deterioration over its shelf life.

A manufacturer of an investigational drug for a serious disease or condition is required to make available, such as by posting on its website, its policy on evaluating and responding to requests for individual patient access to such investigational drug. This requirement applies on the earlier of the first initiation of a Phase 2 or Phase 3 trial of the investigational drug or, as applicable, 15 days after the drug receives a designation as a breakthrough therapy, fast track product, or regenerative advanced therapy.
U.S. Review and Approval Processes

The results of product development, preclinical studies and clinical trials, along with descriptions of the manufacturing process, analytical tests conducted on the product, proposed labeling and other relevant information, are submitted to the FDA as part of an NDA for a new drug or a BLA for a biologic, requesting approval to market the product. The submission of an NDA or BLA is subject to the payment of a substantial user fee;fee, although a waiver of such fee may be obtained under certain limited circumstances. For example, the agency will waive the application fee for the first human drug application that a small business or its affiliate submits for review. The sponsor of an approved NDA or BLA is also subject to an annual prescription drug product and establishment user fees.

program fee.

The FDA reviews all NDAs and BLAs submitted to ensure that they are sufficiently complete for substantive review before it accepts them for filing. The FDA may request additional information rather than accept an NDA or BLA for filing. In this event, the NDA or BLA must be re-submitted with the additional information. The re-submitted application also is subject to review before the FDA accepts it for filing. Once the submission is accepted for filing, the FDA begins an in-depth substantive review. The FDA reviews an NDA to determine, among other things, whether a product is safe and effective for its intended use, and a BLA to determine whether the biologic is safe, pure, and potent for its intended use. The FDA also evaluates whether the product'sproduct’s manufacturing is cGMP-compliant to assure the product'sproduct’s identity, strength, quality and purity. Before approving an NDA or BLA, the FDA typically will inspect the facility or facilities where the product is or will be manufactured. The FDA will not approve an application unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. The FDA may refer the NDA or BLA to an advisory committee for review, evaluation and recommendation as to whether the application should be approved and under what conditions. An advisory committee is a panel of experts, including clinicians and other scientific experts, who provide advice and recommendations when requested by the FDA. The FDA is not bound by the recommendation of an advisory committee, but it considers such recommendations when making decisions.

The approval process is lengthy and difficult, and the FDA may refuse to approve an NDA or BLA if the applicable regulatory criteria are not satisfied or may require additional clinical data or other data and information. Even if such data and information are submitted, the FDA may ultimately decide that the NDA or BLA does not satisfy the criteria for approval. Data obtained from clinical trials are not always conclusive, and the FDA may interpret data differently than we interpret the same data. The


FDA will issue a complete response letter if the agency decides not to approve the NDA or BLA in its present form. The complete response letter usually describes all of the specific deficiencies that the FDA identified in the NDA or BLA that must be satisfactorily addressed before it can be approved. The deficiencies identified may be minor, for example, requiring labeling changes, or major, for example, requiring additional clinical trials. Additionally, the complete response letter may include recommended actions that the applicant might take to place the application in a condition for approval. If a complete


response letter is issued, the applicant may either resubmit the NDA or BLA, addressing all of the deficiencies identified in the letter, or withdraw the application or request an opportunity for a hearing.

If a product receives regulatory approval, the approval may be significantly limited to specific diseases and dosages or the indications for use may otherwise be limited, which could restrict the commercial value of the product. Further, the FDA may require that certain contraindications, warnings or precautions be included in the product labeling. In addition, the FDA may require post-approval studies, including Phase 4 clinical trials, to further assess a product'sproduct’s safety and effectiveness after NDA or BLA approval and may require testing and surveillance programs to monitor the safety of approved products that have been commercialized. The FDA couldmay also approve thean NDA or BLA with a Risk Evaluation and Mitigation Strategy plan("REMS") program to mitigate risks, which could include medication guides, physician communication plans, or elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools.

Regulation of Combination Products in the United States

Certain products may be comprised of components that would normally be regulated under different types of regulatory authorities in certain jurisdictions, and frequentlyin the United States by different centers at the FDA. These products are known as combination products. Specifically, under regulations issued by the FDA, a combination product may be:

Under the FDCA, the FDA is charged with assigning a center with primary jurisdiction, or a lead center, for review of a combination product. That determination is based on the "primary“primary mode of action"action” of the combination product. Thus, if the primary mode of action of a device-drug combination product is attributable to the drug product, the FDA center responsible for premarket review of the drug product would have primary jurisdiction for the combination product. The FDA has also established an Office of Combination Products to address issues surroundingWe are developing combination products using our own drug candidates and provide more certainty to the regulatory review process. That office serves as a focal point for combination product issues for agency reviewers and industry. It is also responsible for developing guidance and regulations to clarify the regulation of combination products, and for assignment of the

third-party drugs.

FDA center that has primary jurisdiction for review of combination products where the jurisdiction is unclear or in dispute.

Expedited Programs

Fast Track Designation

The FDA has a Fast Trackfast track program that is intended to expedite or facilitate the process for reviewing new drugs, including biologics that meet certain criteria. Specifically, new drugs are eligible for Fast Track designation if they are intended to treat a serious or life-threatening disease or condition for which there is no effective treatment and demonstrate the potential to address unmet medical needs for the condition. Fast Tracktrack designation applies to the combination of the product and the specific indication for which it is being studied. The sponsor of a new drug may request the FDA to designate the drug as a Fast Trackfast track product concurrently with, or at any time after, submission of an IND, and the FDA must determine if the drug candidate qualifies for fast track designation within 60 days of receipt of the sponsor'ssponsor’s request.

In addition to other benefits, such as the ability to engage in more frequent interactions with the FDA, the FDA may initiate review of sections of a Fast Track drug'sfast track drug’s NDA or BLA before the application is complete. This rolling review is available if the applicant provides, and the FDA approves, a schedule for the submission of each portion of the NDA or BLA and the applicant pays the applicable user fees.fee. However, the FDA'sFDA’s time period goal for reviewing an application does not begin until the last section of the NDA or BLA is submitted. Additionally, the Fast Trackfast track designation may be withdrawn by the FDA if the FDA believes that the designation is no longer supported by data emerging in the clinical trial process.

Zanubrutinib was granted fast track designation status by the FDA for the treatment of WM. Tislelizumab was granted fast track designation by the FDA for the treatment of HCC.
Accelerated Approval

Under FDA'sFDA’s accelerated approval regulations, the FDA may approve a drug, including a biologic, for a serious or life-threatening illness that provides meaningful therapeutic benefit to patients over existing treatments based upon a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments. In clinical trials, a surrogate endpoint is a marker, such as a laboratory measurement of laboratory or clinical signs of a disease or condition that is thought to predict clinical benefit but is not itself a measure of clinical benefit. Surrogate endpoints can often be measured more easily or more rapidly than clinical endpoints. A drug candidate approved on this basis is subject to rigorous post-marketing compliance requirements, including the completion of post-approval clinical trials sometimes referred to as Phase 4 trials to confirm the effect on the clinical endpoint. Failure to conduct required post-approval studies, or to confirm a clinical benefit during post-marketing studies, will allow the FDA to withdraw the drug from the market on an expedited basis. All promotional materials for drug candidates approved under accelerated regulations are subject to prior review by the FDA.

Zanubrutinib was granted accelerated approval by FDA for the treatment of adult patients with MCL who have received at least one prior therapy.

Breakthrough Designation

        The Food and Drug Administration Safety and Innovation Act, or FDASIA, amended the FDCA to require the FDA

Breakthrough therapy designation is intended to expedite the development and review of a breakthrough therapy. A drug or biologic product can be designated as a breakthrough therapy if it is intended to treat a serious or life-threatening disease or condition and preliminary clinical evidence indicates that it may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints. A sponsor may request that a product be designated as a breakthrough therapy concurrently with, or at


any time after, the submission of an IND, and the FDA must determine if the candidate qualifies for breakthrough therapy designation within 60 days of receipt of the sponsor'ssponsor’s request. If so designated, the FDA shall act to expedite the development and review of the product'sproduct’s marketing application, including by meeting with the sponsor throughout the product'sproduct’s development, providing timely advice to the sponsor to ensure that the development program to gather preclinical and clinical data is as efficient as practicable, involving senior managers and experienced review staff in a cross-disciplinary review, and assigning a cross-disciplinary project lead for the FDA review team to facilitate an efficient review of the development program and to serve as a scientific liaison between the review team and the sponsor, and taking stepssponsor. The designation may be rescinded if the drug candidate does not continue to ensure thatmeet the designcriteria for breakthrough therapy designation.

Zanubrutinib was granted breakthrough therapy designation by the FDA for the treatment of the clinical trials is as efficient as practicable.

adult patients with MCL who have received at least one prior therapy.

Priority Review

        Based on results of the Phase 3 clinical trial(s) submitted in an NDA or BLA, upon the request of an applicant, the

The FDA may grant thean NDA for a new molecular entity or BLA a priority review designation, which sets the target date for FDA action on the application at six months after the FDA accepts the application for filing. Priority review is granted where there is evidence that the proposed product would be a significant improvement in the safety or effectiveness of the treatment, diagnosis, or prevention of a serious condition. If criteria are not met for priority review, the application is subject to the standard FDA review period of ten months after FDA accepts the application for filing. Priority review designation does not change the scientific/medical standard for approval or the quality of evidence necessary to support approval.

The NDA for zanubrutinib was granted priority review by the FDA for the treatment of adult patients with MCL who have received at least one prior therapy.
Post-Approval Requirements

Any products for which we receive FDA approval are subject to continuing regulation by the FDA, including, among other things, record-keeping requirements, reporting of adverse experiences with the product, providing the FDA with updated safety and efficacy information, product sampling and distribution requirements, complying with certain electronic records and signature requirements and complying with FDA promotion and advertising requirements. Moreover, each component of a combination product retains their regulatory status (as a drug or biologic, for example) and is subject to the requirements established by the FDA for that type of component. The FDA strictly regulates labeling, advertising, promotion and other types of information on products that are placed on the market. Products may be promoted only for the approved indications and in accordance with the provisions of the approved label. Further, manufacturers must continue to comply with cGMP requirements, which are extensive and require considerable time, resources and ongoing investment to ensure compliance. In addition, changes to the manufacturing process generally require prior FDA approval before being implemented and other types of changes to the approved product, such as adding new indications and additional labeling claims, are also subject to further FDA review and approval.

The Drug Supply Chain Security Act (“DSCSA”) was enacted in 2013 with the aim of building an electronic system to identify and trace certain prescription drugs distributed in the United States. The DSCSA mandates phased-in and resource-intensive obligations for pharmaceutical manufacturers, wholesale distributors, and dispensers over a 10-year period that is expected to culminate in November 2023. The law’s requirements include the quarantine and prompt investigation of a suspect product to determine if it is illegitimate, and notifying trading partners and FDA of any illegitimate product. Drug manufacturers and their collaborators are also required to place a unique product identifier on prescription drug packages. This identifier consists of the National Drug Code, serial number, lot number and expiration date, in the form of a 2 dimensional data matrix barcode that can be read by humans and machines.
Manufacturers and other entities involved in the manufacturing and distribution of approved products are required to register their establishments with the FDA and certain state agencies and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP and other laws. The cGMP requirements apply to all stages of the manufacturing process, including the production, processing, sterilization, packaging, labeling, storage and shipment of the product. Manufacturers must establish validated systems to ensure that products meet specifications and regulatory requirements and test each product batch or lot prior to its release. We rely, and expect to continue to rely, on third parties for the production of clinical quantities of our drug candidates. Future FDA and state inspections may identify compliance issues at the facilities of our contract manufacturers that may disrupt production or distribution or may require substantial resources to correct.

The FDA may withdraw a product approval or revoke a biologics license if compliance with regulatory requirements is not maintained or if problems occur after the product reaches the market.


Later discovery of previously unknown problems with a


product may result in restrictions on the product or even complete withdrawal of the product from the market. Further, the failure to maintain compliance with regulatory requirements may result in administrative or judicial actions, such as fines, untitled or warning letters, holds on clinical trials, product recalls or seizures, product detention or refusal to permit the import or export of products, refusal to approve pending applications or supplements, restrictions on marketing or manufacturing, injunctions or civil or criminal penalties.

        From time We may undertake or be required to time, legislation is drafted, introduced and passed in Congress that could significantly change the statutory provisions governing the approval, manufacturing and marketing of products regulated by the FDA. In addition to new legislation, FDA regulations and policies are often revised or reinterpreted by the agency in ways that may significantly affect our business and our drug candidates. It is impossible to predict whether further legislative or FDA regulation or policy changes will be enacted or implemented and what the impact of such changes, if any, may be.

undertake a product recall.

Patent Term Restoration and MarketingRegulatory Exclusivity

Depending upon the timing, duration and specifics of FDA approval of the use of our drug candidates, some of our U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, commonly referred to as the Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent restoration term of up to five years as compensation for patent term lost during product development and the FDA regulatory review process. However, patent term restoration cannot extend the remaining term of a patent beyond a total of 14 years from the product'sproduct’s approval date. The patent term restoration period is generally one-half the time between the effective date of an IND and the submission date of an NDA or BLA plus the time between the submission date of an NDA or BLA and the approval of that application, except that this review period is reduced by any time during which the applicant failed to exercise due diligence. Only one patent applicable to an approved product is eligible for the extension and the application for the extension must be submitted prior to the expiration of the patent. The USPTO, in consultation with the FDA, reviews and approves the application for any patent term extension or restoration. In the future, if available, we intend to apply for restorations of patent term for some of our currently owned patents beyond their current expiration dates, depending on the expected length of the clinical trials and other factors involved in the filing of the relevant NDA or BLA; however, there can be no assurance that any such extension will be granted to us.

        Market

Data exclusivity provisions under the FDCA can also delay the submission or the approval of certain applications. The FDCA provides a five-year period of non-patent marketingdata exclusivity within the United States to the first applicant to gain approval of an NDA for a new chemical entity. A drug is a new chemical entity if the FDA has not previously approved any other new drug containing the same active moiety, which is the molecule or ion responsible for the action of the drug substance. During the exclusivity period, the FDA may not accept for review an abbreviated new drug application,NDA, or ANDA, or a 505(b)(2) NDA submitted by another company for another version of such drug where the applicant does not own or have a legal right of reference to all the data required for approval. However, such an application may be submitted after four years if it contains a certification of patent invalidity or non-infringement. The FDCA also provides three years of marketingdata exclusivity for an NDA, 505(b)(2) NDA or supplement to an existing NDA if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application, for example, for new indications, dosages or strengths of an existing drug. This three-year exclusivity covers only the conditions of use associated with the new clinical investigations and does not prohibit the FDA from approving ANDAs for drugs containing the original active agent. Five-year and three-year exclusivity will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA would be required to conduct or obtain a right


of reference to all of the preclinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness.

Pediatric exclusivity is another type of regulatory exclusivity in the United States. Pediatric exclusivity, if granted, provides an additional six months of exclusivity, which runs from the end of other regulatory exclusivity or patent period. Pediatricperiods. This six-month exclusivity may be granted based on the voluntary completion of a pediatric clinical trial in accordance with an FDA-issued "Written Request"‘‘Written Request’’ for such a clinical trial.

Biosimilars and Exclusivity

The Patient Protection and Affordable Care Act, or ACA signed into law on March 23, 2010,PHSA includes a subtitle called the Biologics Price Competition and Innovation Act of 2009 which created an abbreviated approval pathway for biological products shown to be similar to, or interchangeable with, an FDA-licensed reference biological product. This amendment to the PHSA attempts to minimize duplicative testing. Biosimilarity, which requires that there be no clinically meaningful differences between the biological product and the reference product in terms of safety, purity and potency, can be shown through analytical studies, animal studies, and a clinical trial or trials. Interchangeability requires that a product is biosimilar to the reference product and the product must demonstrate that it can be expected to produce the same clinical results as the reference product and, for products administered multiple times, the biologic and the reference biologic may be switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biologic.

A reference biologic is granted twelve12 years of exclusivity from the time of first licensure of the reference product. The first biologic product submitted under the abbreviated approval pathway that is determined to be interchangeable with the reference product has exclusivity against other biologics submitting under the abbreviated approval pathway for the lesser of (i) one year after the first commercial marketing, (ii) 18 months after approval if there is no legal challenge, (iii) 18 months after the

resolution in the applicant'sapplicant’s favor of a lawsuit challenging the biologic'sbiologic’s patents if an application has been submitted, or (iv) 42 months after the application has been approved if a lawsuit is ongoing within the 42-month period.

Orphan Drugs

Under the Orphan Drug Act, the FDA may grant orphan drug designation to drugs, including biologics, intended to treat a rare disease or condition—generallycondition-generally a disease or condition that affects fewer than 200,000 individuals in the United States or that affects more than 200,000 individuals in the United States and for which there is no reasonable expectation that costs of research and development of the product for the indication can be recovered by sales of the product in the United States. Orphan drug designation must be requested before submitting an NDA or BLA.

After the FDA grants orphan drug designation, the generic identity of the drug or biologic and its potential orphan use are disclosed publicly by the FDA. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process. The first NDA or BLA applicant to receive FDA approval for a particular active ingredient to treat a particular disease or condition with FDA orphan drug designation is entitled to a seven-year exclusive marketing period in the United States for that product, for that indication. Among the other benefits of orphan drug designation are tax credits for certain research and a waiver of the NDA or BLA application user fee.

During the exclusivity period, the FDA may not approve any other applications to market the same drug for the same disease or condition, except in limited circumstances, such as if the second applicant demonstrates the clinical superiority of its product to the product with orphan drug exclusivity through a demonstration of superior safety, superior efficacy, or a major contribution to patient care. "Same drug"“Same drug” means a drug that contains the same active moiety if it is a drug composed of small


molecules, or the same principal molecular structural features if it is composed of macromolecules and is intended for the same use as a previously approved drug, except that if the subsequent drug can be shown to be clinically superior to the first drug, it will not be considered to be the same drug. Orphan drug exclusivity does not prevent the FDA from approving a different drug for the same disease or condition, or the same drug for a different disease or condition.

Pediatric Information

        Under

Zanubrutinib was granted orphan drug designation status by the Pediatric Research Equity Act of 2003, as amended, NDAs, BLAs or supplements must contain data adequate to assess the safety and effectiveness of the productFDA for the claimed indications in all relevant pediatric subpopulationstreatment of WM, CLL, and to support dosingMCL. Tislelizumab was granted orphan drug designation status by the FDA for the treatment of ESCC and administration for each pediatric subpopulation for which the product is safe and effective. The FDASIA amended the FDCA to require that a sponsor who is planning to submit a marketing application for a product that includes a new active ingredient, new indication, new dosage form, new dosing regimen or new route of administration submit an initial Pediatric Study Plan, or PSP, within 60 days of an end-of-Phase 2 meeting or as may be agreed between the sponsor and the FDA. The initial PSP must include an outline of the pediatric study or studies that the sponsor plans to conduct, including study objectives and design, age groups, relevant endpoints and statistical approach, or a justification for not including such detailed information, and any request for a deferral of pediatric assessments or a full or partial waiver of the requirement to provide data from pediatric studies along with supporting information. The FDA may, on its own initiative or at the request of the applicant, grant deferrals for submission of data or full or partial waivers. The FDA and the sponsor must reach agreement on the PSP. A sponsor can submit amendments to an agreed-upon initial PSP at any time if changes to the pediatric plan need to be considered based on data collected from preclinical studies, early phase clinical trials, and/or other clinical development programs.

Disclosure of Clinical Trial Information

Sponsors of clinical trials of FDA-regulated products, including drugs and biologics, are required to register and disclose certain clinical trial information, which is publicly available at www.clinicaltrials.gov. Information related to the product, patient population, phase of investigation, study sites and investigators, and other aspects of the clinical trial is then made public as part of the registration. Sponsors are also obligated to disclose the results of their clinical trials after completion. Disclosure of the results of these trials can be delayed until the new product or new indication being studied has been approved. Competitors may use this publicly available information to gain knowledge regarding the progress of development programs.

Pharmaceutical Coverage, Pricing, and Reimbursement

        Significant uncertainty exists as to the coverage and reimbursement status of any products for which we may obtain regulatory approval.

In the United States and in other countries, sales of any products for which we may receive regulatory approval for commercial sale will depend in part on the availability of coverage and reimbursement from third-party payors. Third-party payors, includeincluding government authorities, managed care providers, private health insurers and other organizations. ThePatients generally rely on third-party payors to reimburse all or part of the associated healthcare costs and no uniform policy of coverage and reimbursement for drug products exists among third-party payors. Therefore, coverage and reimbursement for drug products can differ significantly from payor to payor.
Additionally, the process for determining whether a payor will provide coverage for a product may be separate from the process for setting the reimbursement rate that the payor will pay for the product. Third-party payors may limit coverage to specific products on an approved list which might not include all of the FDA-approved products for a particular indication. Moreover, a payor'spayor’s decision to provide coverage for a product does not imply that an adequate reimbursement rate will be approved. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize an appropriate return on our investment in product development.


Third-party payors are increasingly challenging the price and examining the medical necessity and cost-effectiveness of medical products and services, in addition to their safety and efficacy. In order to obtain coverage and reimbursement for any product that might be approved for sale, we may need to conduct expensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of any products, in addition to the costs required to obtain regulatory approvals. Our drug candidates may not be considered medically necessary or cost-effective. If third-party payors do not consider a product to be cost-effective or medically-necessary compared to other available therapies,


they may not cover the product after approval as a benefit under their plans or, if they do, the level of payment may not be sufficient to allow a company to sell its products at a profit.

The U.S. government and state legislatures have shown significant interest in implementing cost containment programs to limit the growth of government-paid health care costs, including price controls, restrictions on reimbursement and requirements for substitution of generic products for branded prescription drugs. For example, the ACA, as amended by the HealthAffordable Care and Education Reconciliation Act of 2010, collectively, the ACA,(the "ACA") contains provisions that may reduce the profitability of drug products, including, for example, increased rebates for drugs reimbursed by Medicaid programs, extension of Medicaid rebates to Medicaid managed care plans, mandatory discounts for certain Medicare Part D beneficiaries and annual fees based on pharmaceutical companies'companies’ share of sales to federal health care programs. Adoption of government controls and measures and tightening of restrictive policies in jurisdictions with existing controls and measures, could limit payments for pharmaceuticals.

The marketabilitycurrent U.S. president's administration’s budget proposals for fiscal years 2019 and 2020 contain further drug price control measures that could be enacted during the 2020 budget process or in other future legislation, including, for example, measures to permit Medicare Part D plans to negotiate the price of anycertain drugs under Medicare Part B, to allow some states to negotiate drug prices under Medicaid, and to eliminate cost sharing for generic drugs for low-income patients. Additionally, the current administration released a “Blueprint” to lower drug prices and reduce out of pocket costs of drugs that contains additional proposals to increase manufacturer competition, increase the negotiating power of certain federal healthcare programs, incentivize manufacturers to lower the list price of their products for which we receive regulatory approval for commercial sale may suffer ifand reduce the governmentout of pocket costs of drug products paid by consumers. The U.S. Department of Health and third-party payors failHuman Services (the "HHS") has already started the process of soliciting feedback on some of these measures and, at the same time, is immediately implementing others under its existing authority. Although a number of these measures and other proposed measures will require authorization through additional legislation to provide adequate coveragebecome effective, U.S. Congress and reimbursement. In addition, an increasing emphasis on cost containment measures in the United States has increased and we expectcurrent administration have each indicated that it will continue to increaseseek new legislative and/or administrative measures to control drug costs. At the pressurestate level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on pharmaceutical pricing. Coverage policiescertain product access and third-party reimbursement rates may change at any time. Even if favorable coveragemarketing cost disclosure and reimbursement status is attained for one or more products for which we receive regulatory approval, less favorable coverage policiestransparency measures, and, reimbursement rates may be implemented in the future.

Other U.S. Healthcare Laws and Compliance Requirements

If we obtain regulatory approval of our products,product candidates, we may be subject to various federal and state laws targeting fraud and abuse in the healthcare industry. These laws may impact, among other things, our proposed sales, marketing and education programs. In addition, we may be subject to patient privacy regulation by both the federal government and the states in which we conduct our business.business prior to and after receiving regulatory approval of our product candidates. The laws that may affect our ability to operate include:

the federal Anti-Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting, receiving, providing, offering or paying any remuneration (including any kickback, bribe, or rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce or reward, or in return for, either the referral of an individual, for, or the purchase, lease, order or recommendation or arrangement of anany good, facility, item or service reimbursablefor which payment may be made, in whole or in part, under a federal healthcare program, such as the Medicare and Medicaid programs;

federal civil and criminal false claims laws and civil monetary penalty laws, such as the federal False Claims Act, which prohibit, among other things,impose criminal and civil penalties and authorize civil whistleblower or qui tam actions, against individuals or entities fromfor, among other things: knowingly presenting, or causing to be presented, to the federal government, claims for payment from Medicare, Medicaid, or other third-party payors that are false, fictitious or fraudulent,fraudulent; knowingly making or makingcausing a false statement or record material to payment of a false or fraudulent claim or obligation to pay or transmit money or property to the federal government; or knowingly concealing or knowingly and improperly avoiding decreasing, or concealingdecreasing an obligation to pay money to the federal government;

government. In addition, the government may assert that a claim including items and services resulting from a violation of the federal Anti-Kickback Statute constitutes a false of fraudulent claim for purposes of the False Claims Act;
the federal Health Insurance Portability and Accountability Act of 1996 ("HIPAA"), which prohibits knowingly and willfully executing, or HIPAA, which created new federal criminal statutes that prohibit executingattempting to execute, a scheme to defraud any healthcare benefit program or obtain, by means of false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit program, regardless of the payor (e.g., public or private) and knowingly and willfully falsifying, concealing or covering up by any trick or device a material fact or making any materially false statements in connection with the delivery of, or payment for, healthcare benefits, items or services relating to healthcare matters;

activities that potentially harm consumers. 

The ACA broadened the reach of the fraud and abuse laws by, among other things, amending the intent requirement of the federal Anti-Kickback Statute and the applicable criminal healthcare fraud statutes contained within 42 U.S.C. § 1320a-7b. Pursuant to the statutory amendment, a person or entity no longer needs to have actual knowledge of this statute or specific intent to violate it in order to have committed a violation. In addition, the ACA provides that the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the civil False Claims Act or the civil monetary penalties statute. Many states have adopted laws similar to the federal Anti-Kickback Statute and False Claims Act, some of which apply to theclaims for, and referral of patients for, healthcare items or services reimbursed by any source, not only the Medicare and Medicaid programs.

Similarly, state privacy laws may be broader and require greater protections than HIPAA. These data privacy and security laws may differ from each other in significant ways and often are not pre-empted by HIPAA, which may complicate compliance efforts. For example, in June 2018, the State of California enacted the California Consumer Privacy Act of 2018 (“CCPA”), which came into effect on January 1, 2020 and provides new data privacy rights for consumers and new operational requirements for companies. The federal False Claims Act prohibits anyone from, among other things, knowingly presenting, or causingCCPA gives California residents expanded rights to be presented,access and delete their personal information, opt out of certain personal information sharing, and receive detailed information about how their personal information is used. CCPA provides for paymentcivil penalties for violations, as well as a private right of action for data breaches that is expected to federal programs (including Medicareincrease data breach litigation. While there is currently an exception for protected health information that is subject to HIPAA and Medicaid) claims for items or services that are false or fraudulent. Although we would not submit claims directly to payors, manufacturers can be held liable under these laws if they are deemed to "cause" the submission of false or fraudulent claims by, for example, providing inaccurate billing or coding information to customers or promoting a product off-label. In addition, our future activities relating to the reporting of wholesaler or estimated retail prices for our products, the reporting of prices used to calculate Medicaid rebate information and other information affecting federal, state, and third-party reimbursement for our products, and the sale and marketingclinical trial regulations, as currently written, CCPA may impact certain of our products,business activities. CCPA could mark the beginning of a trend toward more stringent state privacy legislation in the United States, which could increase our potential liability and adversely affect our business.

Additionally, we are subject to scrutiny under this law. For example,state equivalents of each of the healthcare laws described above, among others, some of which may be broader in scope and may apply to healthcare services reimbursed by any third-party payor, not just governmental payors, but also private insurers. These laws are enforced by various state agencies and through private actions. Some states have passed laws that require pharmaceutical companies have been prosecuted underto comply with the April 2003 Office of Inspector General Compliance Program Guidance for Pharmaceutical Manufacturers and/or other voluntary industry codes of conduct that restrict the payments made to healthcare providers and other potential referral sources. Several states and local laws also impose other marketing restrictions or require pharmaceutical companies to make marketing or price disclosures to the state, require drug manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers, and require the registration of pharmaceutical sales representatives.
Violations of fraud and abuse laws may be punishable by administrative, criminal and/or civil sanctions, including penalties, damages, disgorgement, fines, individual imprisonment, reputational harm, the curtailment or restructuring of our operations, and/or exclusion or suspension from federal False Claims Act in connection with their off-label promotion of drugs. Penalties for a False Claims Act violation include three times the actual damages sustained by the government, plus mandatory civil penalties of between $10,781 and $21,563 for each separate false claim, the potential for exclusion from participation in federalstate healthcare programs such as Medicare and althoughMedicaid and debarment from contracting with the federal False Claims Act is a civil statute, conduct that results in a False Claims Act violation may also implicate various federal criminal statutes.U.S. government. In addition, private individuals have the ability to bring actions on behalf of the U.S. government under the federal False Claims Act and certain states have enacted laws modeled after the federal False Claims Act.


Patient Protection and Affordable Care Act

        In March 2010, the ACA was enacted, which includes measures that have or will significantly change the way health care is financed by both governmental and private insurers. Among the provisions of the ACA of greatest importance to the pharmaceutical industry are the following:

European Data Collection and Privacy Laws
The implementationcollection, use, storage, disclosure, transfer, or other processing of this requirement by Centers for Medicare & Medicaid Services, or CMS, may also provide for the public availability of pharmacy acquisition of costpersonal data, which could negatively impact our sales.

In order for a pharmaceutical product to receive federal reimbursement under the Medicare Part B and Medicaid programs or to be sold directly to U.S. government agencies, the manufacturer must extend discounts to entities eligible to participateincluding personal health data, regarding individuals in the 340B drug pricing program.EU are governed by, as of May 2018, the General Data Protection Regulation (“GDPR”). The required 340B discount on a given productGDPR is calculated based onwide-ranging in scope and imposes several requirements relating to the AMP and Medicaid rebate amounts reported by the manufacturer. The ACA expanded the types of entities eligible to receive discounted 340B pricing, although, under the current stateconsent of the law, withindividuals to whom the exception of children's hospitals, these newly eligible entities will not be eligible to receive discounted 340B pricing on orphan drugs when used forpersonal data relates, the orphan indication. In addition, as 340B drug pricing is determined based on AMP and Medicaid rebate data, the revisionsinformation provided to the Medicaid rebate formulaindividuals regarding data processing activities, the notification of data breaches, certain measures to take when engaging third-party processors, and AMP definition described above could cause the required 340B discount to increase.

The ACA imposed a requirement on manufacturers of branded drugs to provide a 50% discount off the negotiated price of branded drugs dispensed to Medicare Part D patients in the coverage gap (i.e., the "donut hole").

The ACA imposed an annual, nondeductible fee on any entity that manufactures or imports certain branded prescription drugs, apportioned among these entities according to their market share in certain government healthcare programs, although this fee would not apply to sales of certain products approved exclusively for orphan indications.

The ACA required pharmaceutical and biologics manufacturers to track certain financial arrangements with physicians and teaching hospitals, including any "transfer of value" made or distributed to such entities, as well as any investment interests held by physicians and their immediate family members. Manufacturers report this information to CMS annually. The reported information is publicly available in a searchable format on a CMS website.

A new Patient-Centered Outcomes Research Institute was established pursuant to the ACA to oversee, identify priorities in, and conduct comparative clinical effectiveness research, along with

        Since its enactment, there have been judicial and Congressional challenges to numerous aspects of the ACA. In January, Congress voted to adopt a budget resolution for fiscal year 2017 that, while not a law, is widely viewed as the first step toward the passage of legislation to repeal the ACA. Further, on January 20, 2017, President Trump signed an Executive Order directing federal agencies with authorities and responsibilities under the ACA to waive, defer, grant exemptions from, or delay the implementation of any provisionsafeguards to protect the


security and confidentiality of personal data. GDPR also impose strict rules on the transfer of personal data out of the ACA that would impose a fiscal or regulatory burden on states, individuals, healthcare providers, health insurers, or manufacturers of pharmaceuticals or medical devices. Congress also could consider subsequent legislationEuropean Economic Area to replace elementsthe United States. GDPR introduces new data protection requirements in the EU and substantial fines for breaches of the ACAdata protection rules, including potential fines of up to €20 million or 4% of annual global revenues, whichever is greater. GDPR also confers a private right of action on data subjects and consumer associations to lodge complaints with supervisory authorities, seek judicial remedies, and obtain compensation for damages resulting from violations of GDPR. In addition, GDPR includes restrictions on cross-border data transfers. GDPR regulations may impose additional responsibility and liability in relation to personal data that are repealed. We cannot predict how the ACA, its possible repeal, any legislation thatwe process where such processing is subject to GDPR, and we may be proposedrequired to replace the ACA, or the political uncertainty surrounding any repeal or replacement legislation willput in place additional mechanisms ensuring compliance with GDPR, including as implemented by individual countries. This may be onerous and adversely affect our business.

business, financial condition, results of operations, and prospects. Further, the United Kingdom’s decision to leave the EU, often referred to as Brexit, has created uncertainty with regard to data protection regulation in the United Kingdom. In particular, it is unclear how data transfers to and from the United Kingdom will be regulated now that the United Kingdom has left the EU.

PRC Regulation

In the PRC, we operate in an increasingly complex legal and regulatory environment. We are subject to a variety of PRC laws, rules and regulations affecting many aspects of our business. This section summarizes the principal PRC laws, rules and regulations that we believe are relevant to our business and operations.

General Regulations on

PRC Drug Regulation
Introduction
China Foodheavily regulates the development, approval, manufacturing and Drug Administration

        In the PRC, the CFDA monitors and supervises the administration of pharmaceutical products, as well as medical devices and equipment. The CFDA's primary responsibility includes evaluating, registering and approving new drugs, generic drugs, imported drugs and traditional Chinese medicines; approving and issuing permits for the manufacture, export and import of pharmaceutical products and medical appliances; approving the establishment of enterprises for pharmaceutical manufacture and distribution; formulating administrative rules and policies concerning the supervision and administration of food, cosmetics and pharmaceuticals; and handling significant accidents involving these products. The local provincial drug administrative authorities are responsible for supervision and administrationdistribution of drugs, within their respective administrative regions.

including biologics. The PRC Drug Administration Law promulgated by the Standing Committee of the National People's Congress in 1984 and the Implementing Measures of the PRC Drug Administration Law promulgated by the Ministry of Health, or the MOH, in 1989 set forth the legal framework for the administration of pharmaceutical products includingin China is established by the research, development and manufacturing of drugs.

        The PRC Drug Administration Law was revised in December 2001, April 2015, and most recently in January 2017. The purpose of the revisions in 2015 was to strengthenPRC (DAL) enacted by the supervisionStanding Committee of the National People’s Congress on September 20, 1984 and administration of pharmaceutical products and to ensure the quality and safety of those products for


human use.effective from July 1, 1985 (last amended on August 26, 2019, effective from December 1, 2019). The revised PRC Drug Administration Law applies to entities and individuals engaged in the development, production, trade, application,clinical use, as well as supervision and administration of pharmaceutical products.products by regulatory agencies. It regulates and prescribesprovides for a framework for the administration ofregulating pharmaceutical preparations ofmanufacturers, pharmaceutical trading companies, medical institutions, and for the research, development, research, manufacturing, distribution, packaging, pricing, and advertising ofadvertisement activities related to pharmaceutical products. The amendment of PRC Drug Administration Law in January 2017 removed the preview procedure at the provincial level for qualification approval of drug clinical trial institutions. Revised Implementing Measures of the PRC Drug Administration Law promulgated by the State Council took effect in Septemberon August 4, 2002 and was most recentlyeffective from September 15, 2002 and amended inon February 6, 2016 providingand March 2, 2019 provides detailed implementingimplementation regulations for the revised PRC Drug Administration Law.

The Revised Implementing Measures removedDAL
The DAL revised on August 26, 2019 (the "rDAL") embodies an expected regulatory trend to strengthen the obtainmentlife-cycle management of Drug Manufacturing License ordrugs, to balance the development of innovative drugs and generic drugs, and to enhance drug review and enforcement. It also reflects legislative efforts to address prominent problems of the pharmaceutical industry, such as counterfeit and substandard drugs and high drug prices.
The rDAL contains a Drug Distribution License asdedicated chapter on the Marketing Authorization Holder (“MAH”) system. The MAH system has been trialed in a preconditionpilot program across 10 provinces since 2016. Upon the enactment of the rDAL, the MAH system will no longer be a pilot program but will be implemented nationwide. Subject to approval by the NMPA, MAHs will be allowed to transfer their marketing authorizations. It is not sure whether the transferability of MAH will offer more flexibility in structuring cross-border transactions. In addition, the implementation of the MAH system will be accompanied by a range of new requirements for incorporationthe MAHs. For example, a MAH must establish a quality assurance system and be responsible for the whole process and all aspects of a drug manufacturer or a drug distributor, in order to simplify the business administration process for drug companies.

        Under these regulations, we need to follow related regulations for preclinical research, clinical trials, manufacturing and productiondistribution, post-marketing research, adverse drug reaction monitoring and reporting. A foreign MAH will be required to engage a local agent to fulfill the MAH’s obligations and the foreign MAH shall be subject to joint and several liability in the event of new drugs.

Good Laboratories Practice Certificationany wrongdoing. It is unclear how the scope of such joint liability will be defined.

The rDAL no longer requires the certification for Preclinical Research

GLP, good clinical practice ("GCP"), good supply practice ("GSP"), and GMP. However, drug manufacturers and drug distributors must still comply with current GMP and GSP requirements. Pursuant to the rDAL, NMPA and its local counterparts are directed to strengthen their surveillance of drug manufacturers and distributors, including through regular and continuous site inspections, to ensure their compliance. It remains to be seen how clinical trial institutions will ensure self-compliance with GCP requirements and whether there will be more inspections of clinical trial institutions.

The rDAL also requires MAHs, manufacturers, distributors, and medical institutions to establish and implement drug track and trace systems. The NMPA will issue related standards and regulations regarding drug track and trace system. A drug

pharmacovigilance system will also be established to monitor, identify, evaluate and control adverse drug reactions and other possible drug-related problems.
The rDAL creates an expanded access pathway for investigational drugs under which a company sponsor of a clinical trial in China can apply to establish an expanded access treatment program for patients with life-threatening disease who otherwise do not satisfy the inclusion criteria of a clinical trial. To improvequality for expanded access: (1) the qualitydrug must be used for life-threatening diseases that lack effective treatment; (2) the drug must have demonstrated its potential efficacy based on medical observations; (3) such use is in line with ethical principles; (4) such expanded use has been reviewed and approved (although the approval pathway not clear), and has obtained patients’ informed consent; and (5) the drug must be used within the clinical trial institution and used on patients with similar conditions.
The rDAL also significantly increases and expands penalties for violations. Depending on various types of preclinical research,violations, the DAL imposes different penalties, including warnings, confiscation of illegal gains, fines of up to RMB5 million (about $725,000) or up to 30 times of illegal gains, revocation of required business and operating licenses, certificates or approval documents for drugs, suspension of business, temporary (10 years) or permanent debarment of companies, institutions and responsible persons, and criminal liabilities in the case of serious violations.
On October 15, 2019, NMPA published draft measures for soliciting comments on drug registration, and on December 10, 2019, the State Administration for Market Regulation ("SAMR") published draft measures for soliciting comments on drug manufacturing and drug supply. These draft measures reflect the changes in the rDAL, including the MAH system, the abolishment of GLP, GCP, GSP and GMP certification, and the enhancement of administrative penalties on violations.
There are still uncertainties with respect to the interpretation and implementation of the rDAL. We plan to closely monitor the implementation of the rDAL and its impact on our operations in China.
Regulatory Authorities and Recent Government Reorganization
In China, the NMPA is the primary regulator for pharmaceutical products and businesses. The agency was newly formed from the prior China Food and Drug Administration ("CFDA") in 2018 as part of a complete government reorganization. NMPA is no longer an independent agency. Its parent agency is now the newly organized SAMR, into which agencies responsible for, among other areas, consumer protection, advertising, anticorruption, antitrust, fair competition and intellectual property have been merged.
Like the CFDA, promulgated the Administrative Measures for Good Laboratories Practice of Preclinical Laboratory in 2003NMPA is still the chief drug regulatory agency and began to conductimplements the certification program of GLP. In April 2007, the CFDA issued the Circular on Measures for Certification of Good Laboratory Practice, or CFDA Circular 214, providing that the CFDA is responsible for certification of preclinical research institutions. Under CFDA Circular 214, the CFDA decides whether an institution is qualified for undertaking pharmaceutical preclinical research upon the evaluation of the institution's organizational administration, its research personnel, its equipmentsame laws, regulations, rules, and facilities and its operation and management of preclinical pharmaceutical projects. If all requirements are met, a GLP Certification will be issued byguidelines as the CFDA, and the result will be published on the CFDA's website.

        Currently forit regulates almost all our ongoing projects, we cooperated with CFDA certified GLP laboratories operated by Wuxi AppTec (Suzhou) Co., Ltd. and JOINN Laboratories (Beijing) to conduct the studies following GLP based on CFDA requirements.

Approval for Clinical Trials and Production of New Drugs

        According to the Provisions for Drug Registration promulgated by the CFDA in 2007, Drug Administration Law promulgated and amended by the Standing Committee of the National People's Congress in 2015, Circular on Regulations for Special Approval on New Drug Registration issued bykey stages of the CFDA in 2009, and Circular on Information Publish Platform for Pharmaceutical Clinical Trials issued by the CFDA in 2013, we must comply with the following procedures and obtain several approvals forlife-cycle of pharmaceutical products, including nonclinical studies, clinical trials, marketing approvals, manufacturing, advertising and production of new drugs.

Clinical Trial Application

        Upon completion of its preclinical research, a sponsor must apply for approval of a Clinical Trial Application before conducting clinical trials.

Special Examinationpromotion, distribution, and Approval for Domestic Category 1 Pharmaceutical Products

Domestic Category 1 New Drugs Are Eligible for Special Examination and Approval

        According to Provisions for Drug Registration promulgated by the CFDA in 2007, drug registration applications are divided into three different types, namely Domestic NDA, Domestic Generic Drug Application, and Imported Drug Application. Drugs fall into one of three categories, namely chemical medicine, biological product, or traditional Chinese or natural medicine. A Category 1 drug is a new


drug that has never been marketed in any country. All of our clinical-stage drug candidates qualify as domestic Category 1 new drugs.

        According to Provisions on the Administration of Special Examination and Approval of Registration of New Drugs, or the Special Examination and Approval Provisions promulgated by the CFDA in January 2009, the CFDA conducts special examination and approval for new drugs registration application when:

        The Special Examination and Approval Provisions provide that the applicant may file for special examination and approval at the stage of Clinical Trial Application if the drug candidate falls within item (1)post-marketing safety reporting obligations). The provisions provide that for drug candidates that fall within items (2) or (3), the application for special examination and approval must be made when filing for production.

        We believe that BGB-3111, BGB-A317, BGB 290 and BGB-283 fall within items (1) and (2) above. Therefore, we may file an application for special examination and approval at the Clinical Trial Application stage, which may enable us to pursue a more expedited path to approval in China and bring therapies to patients more quickly.

The Advantages of Category 1 New Drugs over Imported Drugs

        Imported drugs are drugs manufactured outside China. Drugs which have already been marketed abroad by multinational companies, but are not yet approved in China are required to follow the process applicable to imported drugs in registration. Compared with the application for imported drugs, the application for Category 1 domestic new drugs has a more straight-forward registration pathway. According to Provisions for Drug Registration, where a special examination and approval treatment is granted, the application for clinical trial and manufacturing will be handled with priority and with enhanced communication with the Center for Drug Evaluation ("CDE"), which remains under the NMPA, conducts the technical evaluation of each drug and biologic application for safety and efficacy.

The National Health Commission ("NHC") (formerly known by the names Ministry of Health ("MOH") and National Health and Family Planning Commission ("NHFPC")), is China’s chief healthcare regulator. It is primarily responsible for overseeing the operation of medical institutions, which also serve as clinical trial sites, and regulating the licensure of hospitals and other medical personnel. The NHC plays a significant role in drug reimbursement. Furthermore, the NHC and its local counterparts at or below the provincial-level of local government also oversee and organize public medical institutions’ centralized bidding and procurement programs for pharmaceutical products. This is the primary way that public hospitals and their internal pharmacies procure drugs.
Also, as part of the CFDA, or2018 reorganization, the CDE,PRC government formed a new State Medical Insurance Bureau which will establish a working mechanism for communicating with the applicants. If it becomes necessaryfocuses on regulating reimbursement under state-sponsored insurance plans.
Preclinical and Clinical Development
The NMPA requires preclinical data to revise the clinical trial scheme or make other major alterations during the clinical trial, the applicant may file an application for communication. According to theAdministrative Measures on Communications for Drug Development and Technical Evaluation issued by CFDA in June 2016, when an application for communication is approved, the CDE will arrange the communication with the applicant within 30 to 60 days, depending on the subject matter of such communication.

        In comparison, according to Provisions for Drug Registration, the registration pathway for imported drugs is complicated and evolving. Imported drug applications may only be submitted after a company obtains an NDA approval and receive the CPP granted by a major regulatory authority, such as the FDA or the EMA. Multinational companies may need to apply for conducting MRCTs, which means that companies do not have the flexibility to design the clinical trials to fit the Chinese patients and standard-of-care. Imported drug candidates under Category 5 cannot qualify for the national priority list to benefit from fast track reviews. Moreover, a requirement to further conduct local clinical trials can potentially delay market access by several years from its international NDA approval.

        Our drug candidates are all new therapeutic agents and thesupport registration applications for all fournew drugs. Preclinical work, including pharmacology and toxicology studies, must meet the GLP standards, issued on August 4, 2003 and amended on July 27, 2017. Although the rDAL no longer requires the NMPA to accredit GLP labs, it still requires that nonclinical studies of themchemical drug substances and preparations and biologics that are filed under Category 1. The CFDA has approved our Clinical Trial Applications for all four of our drug candidates, i.e. BGB-3111, BGB-A317, BGB-283, and BGB-290, including all phases of their clinical trials.


Changes tonot yet marketed in China be conducted in GLP-qualified labs. There are no approvals required from the Review and Approval Process

        In August 2015, the Chinese State Council issued a statement,Opinions on reforming the review and approval process for pharmaceutical products and medical devices, that contained several potential policy changes that could benefit the pharmaceutical industry:

        In November 2015, the CFDA released theCircular Concerning Several Policies on Drug Registration Review and Approval, which further clarified the following policies potentially simplifying and accelerating the approval process of clinical trials:

        In February 2016, the CFDA released theOpinions on Priority Review and Approval for Resolving Drug Registration Applications Backlog, which further clarified the following policies potentially accelerating the approval process of certain clinical trials or drug registrations which may benefit us:

preclinical studies.

        In March 2016, the CFDA released a circular,CFDA Announcement on Reforms of Pharmaceutical Registration Classification, which outlined the re-classifications of drug applications. Under the new categorization, innovative drugs that have not been approved either in or outside China remain Category 1, while drugs approved outside China seeking marketing approval in China are now Category 5.

        The CFDA may release detailed policies regarding such abovementioned fast track clinical trial approval and drug registration pathway, and we expect that the CFDA review and approval process will improve over time. However, how and when this approval process will be changed is still subject to further policies to be issued by the CFDA and is currently uncertain.

Subsidies and Preferential Tax Treatment for "12-5 Major New Drugs Development Projects"

        In 2012, the Chinese State Council adopted a "12-5 Major New Drugs Development Projects," according to which a special fund was established by the government to encourage the development of new drugs. Our BGB-283 drug candidate and another BRAF preclinical research project have been recognized as "12-5 Major New Drugs Development Projects" and received government subsidies of RMB 6,554,600 during the period from January 1, 2013 to December 31, 2015.

PRC Enterprise Income Tax Law and Its Implementation

        The PRC Enterprise Income Tax Law, or EIT Law, and its implementation rules permit certain High and New Technologies Enterprises, or HNTEs, to enjoy preferential enterprise income tax rates subject to these HNTEs meeting certain qualification criteria. In April 2008, the State Administration of Taxation, or SAT, the Ministry of Science and Technology, or MOST and the Ministry of Finance, or MOF jointly issued theAdministrative Rules for the Certification of High and New Technology Enterprises specifying the criteria and procedures for the certification of HNTEs. In January 2016, revised version of theAdministrative Rules for the Certification of High and New Technology Enterprises has been issued by the SAT, the MOST and the MOF, and replaced the 2008 version, while the material criteria of HNTEs remains unchanged.

        Pursuant to the Temporary Regulations on Business Tax, which were promulgated by the Chinese State Council on December 13, 1993 and effective as of January 1, 1994, as amended on November 10, 2008 and effective as of January 1, 2009, any entity or individual conducting business in a service industry is generally required to pay business tax at the rate of 5% on the revenues generated from providing such services. However, if the services provided are related to technological development and transfer, such business tax may be exempted subject to approval by the relevant tax authorities.

        In November 2011, the MOF and the SAT promulgated the Pilot Plan for Imposition of Value-Added Tax, or VAT, to Replace Business Tax, or the Pilot Plan. Since January 2012, the SAT has been implementing the Pilot Plan, which imposes VAT, in lieu of business tax for certain industries in Shanghai. The Pilot Plan was expanded to other regions, including Beijing, in September 2012, and was further expanded nationwide beginning August 1, 2013. VAT is applicable at a rate of 6% in lieu of business taxes for certain services and 17% for the sale of goods and provision of tangible property lease services. VAT payable on goods sold or taxable services provided by a general VAT taxpayer for a taxable period is the net balance of the output VAT for the period after crediting the input VAT for the period.


Four Phases of Clinical Trials

        A clinical development program consists of Phases 1, 2, 3 and 4. Phase 1 refers to the initial clinical pharmacology and safety evaluation studies in humans. Phase 2 refers to the preliminary evaluation of a drug candidate's therapeutic effectiveness and safety for particular indication(s) in patients, provide evidence and support for the design of Phase 3 clinical trial, and settle the administrative dose regimen. Phase 3 refers to clinical trials undertaken to confirm the therapeutic effectiveness of a drug. Phase 3 is used to further verify the drug's therapeutic effectiveness and safety on patients with target indication(s), to evaluate overall benefit-risk relationships of the drug, and ultimately to provide sufficient evidence for the review of drug registration application. Phase 4 refers to a new drug's post-marketing study to assess therapeutic effectiveness and adverse reactions when the drug is widely used, to evaluate overall benefit-risk relationships of the drug when used among general population or specific groups, and to adjust the administration dose, etc.

New Drug Application

        When Phases 1, 2 and 3 of the clinical trials have been completed, the applicant must apply to the CFDA for approval of a NDA. The CFDA then determines whether to approve the application according to the comprehensive evaluation opinion provided by the CDE of the CFDA. We have obtained approval of our Clinical Trial Applications for BGB-283, BGB-3111, BGB-290 and BGB-A317 in the PRC, and clinical trials have been initiated. We must obtain approval of a NDA before our drugs can be manufactured and sold in the PRC market.

Good Manufacturing Practice

        All facilities and techniques used in the manufacture of products for clinical use or for sale in the PRC must be operated in conformity with cGMP guidelines as established by the CFDA. Failure to comply with applicable requirements could result in the termination of manufacturing and significant fines.

Animal Test Permits

        According to Regulations for the Administration of Affairs Concerning Experimental Animals promulgatedissued by the State Science and Technology Commission in("SSTC") on November 14, 1988 (last amended on March 1, 2017), the Administrative Measures on Good Practice of Experimental Animals jointly issued by the SSTC and the State Bureau of Quality and Technical Supervision


on December 11, 1997, and the Administrative Measures on the Certificate for Animal ExperimentationExperimental Animals (Trial) promulgated by the State Science and Technology CommissionSSTC and other regulatory authorities in Januaryon December 5, 2001, performing experimentation on animals requires a Certificate for Use of Laboratory Animals.Animals is required for performing experimentation on animals. Applicants for this certificate must satisfy a number of conditions, including (1) the following conditions:

Registration Categories
Prior to engaging with the NMPA on research and development and approval, an applicant will need to determine the registration category for its drug candidate (which will ultimately need to be confirmed with the NMPA), which will determine the requirements for its clinical trial and marketing application. There are five categories for small molecule drugs: Category 1 (“innovative drugs”) refers to drugs that have a new chemical entity that has not been marketed anywhere in the world, Category 2 (“improved new drugs”) refers to drugs with a new indication, dosage form, route of administration, combination, or certain formulation changes not approved in the world, Categories 3 and 4 are for generics that reference an innovator drug (or certain well-known generic drugs) marketed either abroad or in China, respectively, and Category 5 refers to innovative or generic drugs that have already been marketed abroad but are not yet approved in China (i.e., imported drugs).
Therapeutic biologics follow a similar categorization, with Category 1 being new to the world, but with fifteen product-specific categories. Like with small molecule drugs, Category 1 is for innovative biologics that have not been approved inside or outside of China. A clear regulatory pathway for biosimilars does not yet exist, but something was proposed in a draft revision to an NMPA regulation in 2017. Each of zanubrutinib, tislelizumab, pamiparib and lifirafenib is classified as Category 1 based on the respective clinical trial approval from the NMPA, which is a favored category for clinical trial approval, or CTA, and marketing approval.
Expedited Programs
Priority Evaluation and Approval Programs to Encourage Innovation
The management systemsNMPA has adopted several expedited review and approval mechanisms since 2009 and created additional expedited programs in recent years that are intended to encourage innovation. Applications for these expedited programs can be submitted after the CTA is admitted for review by the CDE. Some of the current categories of drugs eligible for priority status that may be particularly relevant for us include: (1) Category 1 innovative drugs that have not been approved inside or outside of China; (2) oncology drugs; (3) drugs using advanced technology, innovative treatment methods, and having clear therapeutic benefit; and (4) new drugs for which clinical trials are already approved in the United States or EU, or for which marketing authorization applications have been filed simultaneously in China and in the United States or EU and are manufactured in China using the same production line that passed FDA or EMA inspection.
If admitted to one of these expedited programs, an applicant will be entitled to more frequent and timely communication with reviewers at the CDE, expedited review and approval, and more agency resources throughout the approval process. Each of our drug candidates, zanubrutinib, tislelizumab, pamiparib and lifirafenib, is classified as Category 1 based on the respective clinical trial approval from the NMPA.
NMPA also permits conditional approval of certain medicines based on early phase data. Post-approval the applicant may need to conduct a post-market study. The agency has done this for drugs that meet unmet clinical needs for life-threatening illnesses and also for drugs that treat orphan indications. In 2018, NMPA established a conditional approval program for drugs designated by the CDE that have been approved in the US, EU and Japan within the last 10 years and that meet one of three criteria (1) orphan indications, (2) drugs that treat life threatening illnesses for which there are not effective treatment or preventive methods, and (3) drugs that treat life threatening illnesses and that have a clear clinical advantage over other clinical therapies.
CDE Guideline on PD-1/L1 NDA
In addition to the programs and proposals above, the CDE has recently stated that it will permit applicants for PD-1/L1 agents to submit data on a rolling basis based on the current high unmet medical need for PD-1/L1 agents. In February 2018, the CDE released the Guideline on the Basic Requirements of Information and Data for NDA Submissions of anti-PD-1/L1 Monoclonal Antibody Products on recurrent and refractory advanced cancers without standard-of-care therapies. Under the guideline, the sponsor must have a pre-NDA meeting with the CDE regarding the data and the NDA submission. The CDE will permit the following submission for these applicants: (1) an initial NDA submission with full preliminary safety data and effectiveness data, including the results of at least two independent therapeutic efficacy assessments of all patients who are currently enrolled pursuant to all of the protocol’s requirements; (2) during the CDE’s substantive technical review of the NDA,

submission on a rolling basis of follow-up safety and effectiveness data from at least six months from the time of the last enrolled patient showing the duration of the response; and (3) submission of all efficacy and safety data as provided for under the protocol before final approval is granted by the NMPA. Sponsors may also apply for priority review and approval for their NDA to accelerate the progress. If granted, priority status will be applied to various stages of the approval process, including testing, manufacturing site inspection, technical review, and clinical site inspection.
New Policies on Expediting Approval of Imported Oncology Drugs
The PRC government continues to establish measures and incentives to promote the development and swifter approval of marketing for oncology and other innovative drugs. Beginning in May 2018, the PRC eliminated tariffs on a significant number of imported innovative drugs, including oncology drugs, making the importation process more efficient. The PRC government has also stated that it will explore ways to expand access to reimbursement under the state health plans for innovative drugs (particularly for urgently needed oncology drugs).
Clinical Trials and Marketing Approval
Upon completion of preclinical studies, a sponsor typically needs to conduct clinical trials in China for registering a new drug. The materials required for this application and the data requirements are determined by the registration category. The NMPA has taken a number of steps to increase efficiency for approving CTAs, and it has also significantly increased monitoring and enforcement of GCP to ensure data integrity.
Trial Approval
All clinical trials conducted in China for the purpose of seeking marketing approvals must be effective and efficient; and

The applicable entity must follow other requirements as stipulatedapproved by the PRC lawsNMPA and regulations.

        We obtainedconducted at hospitals satisfying GCP requirements. In addition to a Certificatestandalone China trial to support development, imported drug applicants may establish a site in China that is part of an international multicenter trial ("IMCT") at the outset of the global trial. Domestically manufactured drugs are not subject to foreign approval requirements, and in contrast to prior practice, the NMPA has decided to permit those drugs to conduct development via an IMCT as well.

The rDAL has now also adopted an implied approval system for Useclinical trials of Laboratory Animalsnew drugs. Trials can proceed if after 60 business days, the applicant has not received any objections from the CDE, as opposed to the lengthier previous clinical trial pre-approval process in 2012 regardingwhich the scopeapplicant had to wait for affirmative approval. The rDAL also expands the number of ratstrial sites by abolishing the GCP accreditation system and mice.

Trial Register
Pursuant to the Announcement on Drug Clinical Trial Information Platform issued by the NMPA on September 6, 2013, clinical trials approved by the NMPA and conducted in China must be registered and published through the Drug Clinical Trial Information Platform (http://www.chinadrugtrials.org.cn). The applicant shall pre-register the trial information within one month after obtaining the clinical trial approval to obtain the trial’s unique registration number and shall complete registration of certain follow-up information before the first subject’s enrollment in the trial. If the foregoing pre-registration and registration is not obtained within one year after obtaining the clinical trial approval, the applicant shall submit an explanation, and if the procedure is not completed within three years, the clinical trial approval automatically expires.
Human Genetic Resources Regulation
On June 10, 2019, China's State Council promulgated the Regulation on the Administration of Human Genetic Resources (HGR Regulation), which became effective on July 1, 2019. The HGR Regulation applies to all human genetic resources (HGR)-related activities for R&D purposes, including sampling, biobanking, use of HGR materials and associated data in China, and provision of such to foreign parties.
According to the HGR Regulation, foreign parties (including foreign entities and entities established or actually controlled by foreign entities and individuals) seeking access to China’s HGRs for scientific research, including clinical trials intended to support marketing approval of drugs and medical devices in China, must do so only through collaborations with Chinese parties. The HGR Regulation now prohibits foreign parties from independently sampling or biobanking any China HGR in China and it adds an approval requirement for the sampling of certain HGR and biobanking of all HGR by Chinese parties. Any cross-border transfer of the HGR materials, either under an international collaboration or as a direct export, must be on an as-needed basis and requires approval. In addition, providing the HGR data to foreign parties requires a record filing.
Another significant change is the HGR Regulation replaced the advance approval requirement with a record-filing procedure for international collaborations on clinical trials intended to support marketing approval of drugs in China that do not transfer HGR materials abroad, while the advance approval requirement still applies if such trials involve export of HGR

materials or the collection, testing, analysis or disposals of HGR samples during the trials are not solely conducted at the clinical trial sites. It is unclear how this record-filing procedure will be implemented in practice and to what extent companies will benefit from it.
The HGR Regulation retains the provision in the Interim Measures for the Administration of Human Genetic Resources issued in 1998 (the "Interim Measures") that parties should jointly apply for and own the patent rights arising from the results generated from international collaborations that utilize China HGR. Subject to approval, the parties may contractually agree on how to dispose of their patent rights and non-patent proprietary rights arising from the collaboration. As the joint ownership requirement is rather broad, it is unclear how this requirement will be implemented in practice.
The HGR Regulation also significantly increases and expands penalties for various violations, including warnings, disgorgement of illegal gains, confiscation of illegal HGR, fines up to RMB10 million ($1,450,000) or 5-10 times of illegal gains in the event such illegal gains exceed RMB1 million ($145,000), and temporary (1-5 years) or permanent debarment of companies, institutions and responsible persons from future HGR projects regulated by the HGR Regulation.
As uncertainties exist as to how the HGR Regulation may be interpreted and implemented, we are still evaluating its potential impact on our HGR-related activities and practices. We expect that HGR-related activities will receive greater attention and focus from regulators going forward.
Trial Exemptions and Acceptance of Foreign Data
The NMPA may reduce requirements for trials and data, depending on the drug and the existing data. The NMPA has granted waivers for all or part of trials, and has stated that it will accept data generated abroad (even if not part of a global study), including early phase data, that meets its requirements. On July 6, 2018, the NMPA issued the Technical Guidance Principles on Accepting Foreign Drug Clinical Trial Data (the “Guidance Principles”), as one of the implementing rules for the Opinions on Deepening the Reform of the Evaluation and Approval Systems and Encouraging Innovation on Drugs and Medical Devices (the “Innovation Opinion”). According to the Guidance Principles, the data of foreign clinical trials must meet the authenticity, completeness and accuracy requirements and such data must be obtained in compliance with the relevant requirements under the GCP of the International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use ("ICH"). Sponsors must be attentive to potentially meaningful ethnic differences in the subject population.
The NMPA now officially permits, and its predecessor agencies have permitted on a case-by-case basis in the past, drugs approved outside of China to be approved in China on a conditional basis without the need for pre-approval clinical trials in China. Specifically, in 2018, the NMPA established a program permitting drugs that have been approved within the last ten years in the United States, EU or Japan to be approved in China on a conditional basis without local clinical trials if they (1) prevent or treat orphan diseases, (2) prevent or treat serious life-threatening illnesses for which there is either no effective therapy in China, or for which the foreign-approved drug would have clear clinical advantages. Applicants for such conditional approvals will be required to establish a risk mitigation plan and may be required to complete trials in China after the drug is approved. The CDE has developed a list of drugs that meet these criteria.
Clinical Trial Process and Good Clinical Practices
Typically drug clinical trials in China have three phases. Phase 1 refers to the initial clinical pharmacology and human safety evaluation studies. Phase 2 refers to the preliminary evaluation of a drug candidate’s therapeutic efficacy and safety for target indication(s) in patients. Phase 3 (often the pivotal study) refers to clinical trials to further verify the drug candidate’s therapeutic efficacy and safety on patients with target indication(s) and ultimately provide sufficient evidence for the review of a drug registration application. The NMPA requires that the different phases of clinical trials in China receive ethics committee approval prior to approval of the CTA and comply with GCP. The NMPA conducts inspections on clinical trials conducted in China to assess GCP compliance and may refuse to approve the drug if it finds substantial issues in the trials. In addition, upon granting the drug registration certificate, NMPA may, at its sole discretion, require a Phase 4 trial to be conducted by MAH within a specified period of time so as to further monitor and obtain safety and efficacy data of the drug.
Generic small molecule drugs are required to conduct a bioequivalence trial, in vitro studies or in some cases a clinical trial to demonstrate therapeutic equivalence to an innovator drug marketed either in China or abroad or an internationally accepted generic drug. The NMPA has released catalogues of reference products, and it released first installment of a Marketed Drug List (China’s “Orange Book”) with information about drugs that may serve as reference products.
Pursuant to GCP, the sponsor of a clinical trial shall be responsible for proper packaging and labeling of drugs used for clinical trials, and in double-blinded clinical trials, the investigational drugs shall be consistent with the control drug or placebo in appearance, odor, packaging, labeling, and certain other features. According to the Measures for the Administration of

Pharmaceutical Packaging promulgated on February 12, 1988 and effective from September 1, 1988, pharmaceutical packaging must comply with national and professional standards. If there is no national or professional standard available, companies may formulate and implement its own standards after obtaining the approval of the provincial administration for medical products or bureau of standards. Changes in such approved packaging standards need to be re-approved. Drugs of which the packaging standards are not approved shall not be released or marketed in China (except for those specifically supplied to the military).
New Drug Application ("NDA") and Approval
Upon completion of clinical trials, a sponsor may submit clinical trial data to support marketing approval for the drug.
NDA sponsors must submit data derived from domestically manufactured drugs in support of a drug approval. Under the rDAL, upon approval of the registration application, the NMPA will issue a drug registration certificate to the applicant which is in fact the marketing approval of the drug, and the applicant is no longer required to be equipped with relevant manufacturing capability.
Manufacturing and Distribution
According to the rDAL, all facilities that make drugs in China must receive a drug manufacturing license with an appropriate “scope of manufacturing” from the local drug regulatory authority. This license must be renewed every five years, and the manufacturing facility is also required to be in compliance with GMP.
Similarly, to conduct sales, importation, shipping and storage (“distribution activities”), a company must obtain a Drug Distribution License from the local drug regulatory authority, subject to renewal every five years. Like with GMPs, companies are required to be in compliance with GSP.
China has formed a “Two-Invoice System” to control distribution of prescription drugs. The “Two-Invoice System” generally requires that no more than two invoices may be issued throughout the distribution chain, with one from the manufacturer to a distributor and another from the distributor to the end-user hospital. This excludes the sale of products invoiced from the manufacturer to its wholly owned or controlled distributors, or for imported drugs, to their exclusive distributor, or from a distributor to its wholly owned or controlled subsidiary (or between the wholly owned or controlled subsidiaries). However, the system still significantly limits the options for companies to use multiple distributors to reach a larger geographic area in China. Compliance with the Two-Invoice System will become a prerequisite for pharmaceutical companies to participate in procurement processes with public hospitals, which currently provide most of China’s healthcare. Manufacturers and distributors that fail to implement the Two-Invoice System may lose their qualifications to participate in the bidding process. Non-compliant manufacturers may also be blacklisted from engaging in drug sales to public hospitals in a locality.
The Two-Invoice System was first implemented in 11 provinces that are involved in pilot comprehensive medical reforms, but the program has expanded to nearly all provinces, which have their own individual rules for the program.
Post-Marketing Surveillance
Under the rDAL, the MAH of a drug is ultimately responsible for pharmacovigilance, including quality assurance, adverse reaction reporting and monitoring, and product recalls. Distributors and user entities (e.g., hospitals) are also required to report, in their respective roles, adverse reactions of the products they sell or use, and assist with the manufacturer of the product recall. A drug that is currently under the new drug monitoring period has to report all adverse drug reactions (as opposed to just serious adverse reactions) for that period.
Advertising and Promotion of Pharmaceutical Products
China has a strict regime for the advertising of approved medicines. No unapproved medicines may be advertised. The definition of an advertisement is very broad, and does not expressly exclude scientific exchange. It can be any media that directly or indirectly introduces the product to end users. There is no clear line between advertising and any other type of promotion.
An enterprise seeking to advertise a prescription drug may do so only in medical journals jointly approved by NMPA and the NHC, and each advertisement requires approval from a local drug regulatory authority. The content of an approved advertisement may not be altered without filing a new application for approval.
Prescription drug advertisements are subject to strict content restrictions, which prohibit recommendations by doctors and hospitals and guarantees of effectiveness. Advertising that includes content that is outside of the drug’s approval documentation (“off-label content”) is prohibited. False advertising can result in civil suits from end users and administrative liability,

including fines. In addition to advertisements, non-promotional websites that convey information about a drug must go through a separate approval process by a local drug regulatory authority.
Regulatory Intellectual Property Protections
On January 15, 2020, the United States and China signed the Economic and Trade Agreement Between the United States of America and the PRC (the “Trade Agreement”). Among other things, China has agreed to provide for effective protection and enforcement of pharmaceutical-related intellectual property rights, including patents and undisclosed test or other data submitted as a condition of marketing approval, as further described below. These provisions of the Trade Agreement will need to be implemented in China.
Non-Patent Exclusivities
New Drug Monitoring Period
Currently, new varieties of domestically produced drugs approved under Categories 1 or 2 in China may be placed under a monitoring period for three to five years. Category 1 innovative drugs will be monitored for five years. During the monitoring period, the NMPA will not approve another CTA from another applicant for the same type of drug, except if another sponsor has an approved CTA at the time that the monitoring period is initiated it may proceed with its trial and once approved become another drug that is part of the monitoring period.
Regulatory Data Protection
The Innovation Opinion also lays the foundation to improve and implement the system for regulatory data protection to protect innovators. This protection will be available to the undisclosed clinical trial data of drugs falling into the following categories: innovative drugs, innovative therapeutic biologics, drugs that treat orphan diseases, pediatric drugs, and drugs for which there has been a successful patent challenge. In the Trade Agreement, China has committed to providing for effective protection of undisclosed test or other data submitted as a condition of marketing approval.
NMPA published a draft on Implementing Regulations for Pharmaceutical Study Data Protection for public comment that would set regulatory data protection for innovative small molecule drugs at six years and for innovative therapeutic biologics at 12 years; pediatric and orphan drugs would receive six years to run concurrently from their approval dates. Full terms of protection would require reliance on local trials or sites of multi-center trials in China and simultaneous submissions of marketing applications in China and other countries. Submissions in China that are up to six years later than those abroad would result in the term being reduced to 1-5 years. Submissions over six years later in China may not receive protection.
There is also a reduction if the marketing application is filed in China based solely on overseas clinical data with no Chinese subjects (75% reduction) or based on supplemental “China clinical trial data” (50% reduction). Information about the exclusivity term will be included in a Marketed Drug List (similar to the Orange Book in the US) at the time of approval. Some mechanics of these proposed rules are not yet clear, and it is not certain when the proposed rules will be finalized.
Patent-Related Protections
Patent LawLinkage
The Innovation Opinion also sets forth the basic elements of a patent linkage system to protect innovators, in which a follow-on applicant will be required to specify patents that are relevant to its application and notify relevant patent right holders (including, innovators) within a specified period after filing its application, permitting them to sue to protect their rights. The system will require that the NMPA continue to review the potentially infringing follow-on application during any lawsuit by the innovator. However, the NMPA may not approve the follow-on application pending resolution of the patent litigation in favor of the follow-on application or for a specified period of time, whichever is shorter. Similarly, the Trade Agreement also adopts certain elements of a patent linkage system: notice to the patent right holder of the follow-on application; and time and opportunity for that right holder to sue and seek expeditious remedies to obtain a timely resolution of the patent dispute. However, the Trade Agreement does not explicitly mention a stay of marketing approval of the follow-on application. It will require legislation and implementing regulations to introduce a patent linkage system into China, and it is not clear when these will be adopted and implemented.
Patent Term Extension
In early 2019, pursuant to the Innovation Opinion, the National People’s Congress issued a proposal for patent term extension as part of a proposed amendment to the Patent Law. Under this proposal, the State Council may grant a patent term extension of up to five years to compensate for delays in the review process for innovative drugs that are applying

simultaneously for marketing approval in both China and abroad. The patent term may not be extended to more than 14 years post-marketing. The Trade Agreement also provides for patent term extension to compensate for unreasonable delay that occurs during pharmaceutical product marketing approvals. It is not clear when this will be implemented.
Reimbursement and Pricing
China’s national medical insurance program was adopted pursuant to the Decision of the State Council on the Establishment of the Urban Employee Basic Medical Insurance Program issued by the State Council in 1998, under which all employers in urban cities are required to enroll their employees in the basic medical insurance program. The insurance premium is jointly contributed by the employers and employees. In 2007, the State Council promulgated Guiding Opinions of the State Council about the Pilot Urban Resident Basic Medical Insurance, under which urban residents of the pilot district, rather than urban employees, may voluntarily join Urban Resident Basic Medical Insurance. Participants of the national medical insurance program and their employers, if any, are required to contribute to the payment of insurance premiums on a monthly basis. Program participants are eligible for full or partial reimbursement of the cost of medicines included in the National Reimbursement Drug List (the "NRDL"). A pharmaceutical product listed in the NRDL must be clinically needed, safe, effective, reasonably priced, easy to use, and available in sufficient quantity.
Factors that affect the inclusion of a pharmaceutical product in the NRDL include whether the product is consumed in large volumes and commonly prescribed for clinical use in the PRC and its implementation rules, patentswhether it is considered to be important in meeting the basic healthcare needs of the general public. Since 2016, special consideration has been given to, among others, innovative drugs with high clinical value and drugs for serious diseases. In addition, the PRC fallMinistry of Human Resources and Social Security has also been negotiating with manufacturers of expensive drugs with high clinical demands and proven effectiveness for price cuts in exchange for inclusion into three categories, namely invention patent, utility model and design patent. Invention patent refers to a new technical solution proposed in respect of a product, method or its improvement; utility model refers to a new technical solution that is practicable for application and proposed in respectthe NRDL. The version of the shape, structureNRDL released in 2019 covers 2,643 drugs in total, including 148 new additions and 150 new deletions as compared with the previous version, with an emphasis on innovative drugs and drugs that treat cancer and other serious diseases. China has been pursuing a policy of expediting the addition of innovative oncology drugs to this list. In 2019, 17 more oncology drugs, including VIDAZA(azacytidine), were added into the NRDL by the State Medical Insurance Bureau.
Government Price Controls
The Chinese government has abolished the 15-year-old government-led pricing system for drugs, and lifted the maximum retail price for most drugs, including drugs reimbursed by government medical insurance funds, patented drugs, and some other drugs. The government regulates prices mainly by establishing a consolidated procurement mechanism, restructuring medical insurance reimbursement standards and strengthening regulation of medical and pricing practices as discussed below.
Centralized Procurement and Tenders
Under current regulations, public medical institutions owned by the government or a combinationowned by state-owned or controlled enterprises are required to purchase pharmaceutical products through centralized online procurement processes. There are exceptions for drugs on the National List of both of a product;Essential Drugs, which must comply with their own procurement rules, and design patent refersfor certain drugs subject to the new designcentral government’s special control such as toxic, radioactive and narcotic drugs, and traditional Chinese medicines.
The centralized procurement process takes the form of public tenders operated by provincial or municipal-level government agencies. The centralized tender process is typically conducted once every year. The bids are assessed by a certain product in shape, pattern orcommittee randomly selected from a combinationdatabase of both and in color, shape and pattern combinations aesthetically suitable for industrial application. Underexperts. The committee members assess the Patent Law of the PRC, the term of patent protection starts from the date the patent was filed. Patents relating to utility-models and designs are effective for ten years from the initial date the patent application was filed. The Patent Law of the PRC adopts the principle of "first to file," which means where more than one person files a patent application for the same invention, a patent will be granted to the person who first filed the application.

        Existing patents can become invalid or unenforceable due tobids based on a number of factors, including known or unknown prior art, deficiencies in patent applicationbut not limited to bid price, product quality, clinical effectiveness, product safety, level of technology, qualifications and lackreputation of novelty in technology. In the PRC, a patent must have novelty, innovationmanufacturer, after-sale services and practical application. Underinnovation.

Over the Patent Law of PRC, novelty means that before a patent application is filed, no identical invention or utility modellast decade, the government has been publicly disclosedusing various methods to ensure that drugs are offered at affordable prices. In 2009, the central government announced a campaign to implement a “zero markup” policy on essential drugs among basic healthcare institutions, which has been fully implemented nationwide. In addition, some local government have begun to allow medical institutions to collectively negotiate with manufacturers for a second price to further lower the already agreed bid price. The newly adopted Two-Invoice System is also aimed to reduce price mark-ups brought about by multi-tier distribution chains.
On January 1, 2019, the State Council approved a volume-based, centralized drug procurement program as part of a trial in any publication11 major cities in an effort to deepen the reform of the medical and health sector and optimize the pricing of drugs. According to the State Council, in these 11 cities, drugs will be selected from generic brands for volume-based, centralized drug procurement. The selected drugs must pass the equivalence evaluation on quality and efficacy. The program is aimed at further lowering drug costs for patients, reducing transaction costs for enterprises, regulating drug use by institutions, and improving the centralized drug procurement and pricing system. All approved enterprises that produce drugs on the procurement list in

China may participate. Clinical effects, adverse reactions, and batch stability of the drugs will be considered, and their consistency will be the main criteria for evaluation, while production capacity and stability of the supplier will also be considered. On September 30, 2019, nine ministry-level agencies (including the State Medical Insurance Bureau, NMPA, and NHC) jointly issued a plan intending to expand this program nationwide.
Other PRC National and Provincial Laws and Regulations
We are subject to changing regulations under many other laws and regulations administered by governmental authorities at the national, provincial and municipal levels, some of which are or may become applicable to our business. For example, regulations control the confidentiality of patients’ medical information and the circumstances under which patient medical information may be released for inclusion in our databases or released by us to third parties. The privacy of human subjects in clinical trials is also protected under regulations. For example, the case report forms must avoid disclosing names of the human subjects.
These laws and regulations governing both the disclosure and the use of confidential patient medical information may become more restrictive in the future, including restrictions on transfer of healthcare data. The Cybersecurity Law that took effect in 2017 designates healthcare as a priority area that is part of critical information infrastructure, and China’s cyberspace administration is working to finalize a draft rule on cross-border transfer of personal information.
PRC or abroad or has been publicly used or made known toRegulation of Foreign Investment
On March 15, 2019, the public by any other means, whether in or outside of China, nor has any other person filed withNational People’s Congress published the patent authority an application that describes an identical invention or utility model and is published after the filing date. Patents in the PRC are filed with the State Intellectual Property Office, or SIPO. Normally, the SIPO publishes an application for a pharmaceutical invention 18 months after the application is filed, which may be shortened upon request by the applicant. The applicant must apply to the SIPO for a substantive examination within three years from the date the application is filed.

        Article 20 of the PatentForeign Investment Law of the PRC provides that, for an invention or utility model completed in China, any applicant, not just Chinese companies(the “Foreign Investment Law”), and individuals, before filing a patent application outside of China, must first submit iton December 26, 2019, the State Council promulgated the Implementing Rules to the SIPOForeign Investment Law of the PRC (the “Implementing Rules”) to further clarify and elaborate the relevant provisions of the Foreign Investment Law. The Foreign Investment Law and the Implementing Rules, both took effect on January 1, 2020. The Foreign Investment Law and the Implementing Rules replaced major previous laws and regulations governing foreign investment in China. They establish the basic framework for the access to, and the promotion, protection and administration of foreign investments in view of investment protection and fair competition and embody an expected regulatory trend to rationalize China’s foreign investment regulatory regime in line with prevailing international practice and the legislative efforts to unify the corporate legal requirements for both foreign and domestic investments. The Implementing Rules further clarified that the state encourages and promotes foreign investment, protects the lawful rights and interests of foreign investors, regulates foreign investment administration, continues to optimize foreign investment environment, and advances a confidential examination. Failurehigher-level opening.

The Foreign Investment Law and the Implementing Rules provide that a system of pre-entry national treatment and negative list shall be applied for the administration of foreign investments, where “pre-entry national treatment” means that the treatment given to foreign investors and their investments at market access stage is no less favorable than that given to domestic investors and their investments, and “negative list” means the special administrative measures for foreign investment’s access to specific fields or industries, which will be proposed by the competent investment department of the State Council in conjunction with the competent commerce department of the State Council and other relevant departments, and be reported to the State Council for promulgation, or be promulgated by the competent investment department or competent commerce department of the State Council after being reported to the State Council for approval. Foreign investments beyond the negative list will be granted national treatment. Foreign investors shall not invest in the prohibited fields as specified in the negative list, and foreign investors who invest in the restricted fields shall comply with this requirementthe special requirements on the shareholding, senior management personnel, etc. In the meantime, relevant competent government departments will resultformulate a catalogue of industries for which foreign investments are encouraged according to the needs for national economic and social development, to list the specific industries, fields and regions in the denial of any Chinese patent for the subject invention. This added requirement of confidential examination by the SIPO has raised concerns bywhich foreign companies who conduct researchinvestors are encouraged and developmentguided to invest. The current industry entry clearance requirements governing investment activities in the PRC or outsourceby foreign investors are set out in two categories, namely the Special Entry Management Measures (Negative List) for the Access of Foreign Investment (2019 version), and the Encouraged Industry Catalogue for Foreign Investment (2019 version) (the “2019 Encouraged Industry Catalogue”), both were promulgated by the National Development and Reform Commission and the Ministry of Commerce (the “MOFCOM”) and took effect on July 30, 2019. Industries not listed in these two categories are generally deemed “permitted” for foreign investments unless specifically restricted by other PRC laws. Pursuant to the 2019 Encouraged Industry Catalogue, the research, development and development activities to service providersmanufacture of innovative oncology drugs and certain other kinds of pharmaceutical products falls in the PRC. Currently weencouraged industries for foreign investment.
On December 30, 2019, the MOFCOM and the SAMR jointly promulgated Measures for Information Reporting on Foreign Investment, which became effective on January 1, 2020. Pursuant to the Measures for Information Reporting on Foreign Investment, where a foreign investor carries out investment activities in China directly or indirectly, the foreign investor or the foreign-invested enterprise shall submit the investment information to the competent commerce department.

Regulations Relating to Foreign Exchange and Dividend Distribution

Foreign Exchange Regulation

The Foreign Exchange Administration Regulations most recently amended in August 2008, are the principal regulations governing foreign currency exchange in China. Under the PRC foreign exchange regulations, payments of current account items, such as profit distributions and trade and service-related foreign exchange transactions, may be made in foreign currencies without prior approval from the State Administration of Foreign Exchange or SAFE,("SAFE") by complying with certain procedural requirements. In contrast, approval from or registration with appropriate government authorities or designated banks is


required when RMB is to be converted into a foreign currency and remitted out of China to pay capital expenses such as the repayment of foreign currency-denominated loans.

        In August 2008, SAFE issued

Under current regulations, the Circular on the Relevant Operating Issues Concerning the Improvement of the Administration of the Payment and Settlement of Foreign Currency Capital of Foreign-Invested Enterprises, or SAFE Circular 142, regulating the conversion by a foreign-invested enterprise of foreign currency-registered capital into RMB by restricting how the converted RMB may be used. In addition, SAFE promulgated Notice on Issues concerning Further Clarifying and Regulating the Foreign Exchange Administration under Some Capital Accounts, or Circular 45, on November 9, 2011 to clarify the application of SAFE Circular 142. Under SAFE Circular 142 and Circular 45, RMB capital converted from foreign currency registered capital of a foreign-invested enterprise may only be used for purposes within the business scope approved by the applicable government authority and may not be used for equity investments within the PRC. In addition, SAFE strengthened its oversight of the flow and use of the RMB capital converted from foreign currency registered capital of foreign-invested enterprises. The use of such RMB capital may not be changed without SAFE's approval, and such RMB capital may not, in any case, be used to repay RMB loans whose proceeds were not used. Furthermore, SAFE promulgated Notice on Issues Concerning Strengthening Administration of Foreign Exchange Services in November 2010, which tightens the regulation over settlement of net proceeds from overseas offerings, such as our initial public offering, and requires, among other things, the authenticity of settlement of net proceeds from offshore offerings to be closely examined and the net proceeds to be settled in the manner described in our prospectus or otherwise approved by our board of directors. Violations of these SAFE regulations may result in severe monetary or other penalties, including confiscation of earnings derived from such violation activities, a fine of up to 30% of the RMB funds converted from the foreign invested funds or in the case of a severe violation, a fine ranging from 30% to 100% of the RMB funds converted from the foreign-invested funds.

        In November 2012, SAFE promulgated the Circular of Further Improving and Adjusting Foreign Exchange Administration Policies on Foreign Direct Investment, which substantially amends and simplifies the current foreign exchange procedure. Pursuant to this circular, the opening of various special purpose foreign exchange accounts, such as pre-establishment expenses accounts, foreign exchange capital accounts and guarantee accounts, the reinvestment of RMB proceeds by foreign investors in the PRC, and remittance of foreign exchange profits and dividends by a foreign-invested enterprise to its foreign shareholders no longer require the approval or verification of SAFE, and multiple capital accounts for the same entity may be opened in different provinces, which was not previously possible. In addition, SAFE promulgated the Circular on Printing and Distributing the Provisions on Foreign Exchange Administration over Domestic Direct Investment by Foreign Investors and the Supporting Documents in May 2013, which specifies that the administration by the SAFE or its local branches over direct investment by foreign investors in the PRC will be conducted by way of registration, and banks must process foreign exchange business relating to the direct investment in the PRC based on the registration information provided by SAFE and its branches.

        Under the Circular of the SAFE on Further Improving and Adjusting the Policies for Foreign Exchange Administration under Capital Accounts promulgated by the SAFE on January 10, 2014 and effective from February 10, 2014, administration over the outflow of the profits by domestic institutions has been further simplified. In principle, a bank is no longer required to examine transaction documents when handling the outflow of profits of no more than the equivalent of $50,000 by a domestic institution. When handling the outflow of profits exceeding the equivalent of $50,000, the bank, in principle, is no longer required to examine the financial audit report and capital verification report of the domestic institution, provided that it must examine, according to the principle of transaction authenticity, the profit distribution resolution of the board of directors, or the profit distribution resolution of the partners, relating to this profit outflow and the original copy of its tax record-filing form. After each profit outflow, the bank must affix its seal to and endorsements on the


original copy of the relevant tax record-filing form to indicate the actual amount of the profit outflow and the date of the outflow.

        On March 30, 2015, SAFE promulgated the Circular on Reforming the Management Approach regarding the Settlement of Foreign Exchange Capital of Foreign-invested Enterprises, or SAFE Circular 19, which became effective on June 1, 2015. According to SAFE Circular 19, the foreign exchange capital of foreign-invested enterprises may be settled on a discretionary basis, meaning that the foreign exchange capital in the capital account of a foreign-invested enterprise for which the rights and interests of monetary contribution has been confirmed by the local foreign exchange bureau, or the book-entry registration of monetary contribution by the banks, can be settled at the banks based on the actual operational needs of the foreign-invested enterprise. The proportion of such discretionary settlement is temporarily determined as 100%. The RMB converted from the foreign exchange capital will be kept in a designated account, and if a foreign-invested enterprise needs to make further payment from such account, it still must provide supporting documents and go through the review process with the banks.

        Furthermore, SAFE Circular 19 stipulates that the use of capital by foreign-invested enterprises must adhere to the principles of authenticity and self-use within the business scope of enterprises. The capital of a foreign-invested enterprise and capital in RMB obtained by the foreign-invested enterprise from foreign exchange settlement must not be used for the following purposes:


indirectly used for investment in securities, unless otherwise provided by relevant laws and regulations;

(3)
directly or indirectly used for granting the entrusted extending loans in RMB,to non-related parties, unless permitted by the scope of business, repaying the inter-enterprise borrowing, including advances by the third party, business; and/or repaying the bank loans in RMB that have been sub-lent to the third party; and/or

(4)
paying the expenses related to the purchase of real estate that is not for self-use, except for the foreign-invested real estate enterprises.

        On June 19, 2016, SAFE promulgated the Circular on Reforming and Regulating Policies on the Control over Foreign Exchange Settlement of Capital Accounts, or Circular 16,

In 2017, new regulations were adopted which, took effect on the same day. Compared to Circular 19, Circular 16 provides that discretionary foreign exchange settlement applies to foreign exchange capital, foreign debt offering proceeds and remitted foreign listing proceeds, and the corresponding Renminbi obtained from foreign exchange settlement are not restricted to extending loans to related parties or repaying the inter-company loans, including advances by third parties. However, since Circular 16 came into effect recently, there are substantial uncertainties with respect to its interpretation and implementation in practice.

        On January 26, 2017, SAFE promulgated the Circular on Further Improving Reform of Foreign Exchange Administration and Optimizing Genuineness and Compliance Verification, or Circular 3, which took effect on the same day. Circular 3 sets out various measures with the following key contents:

On October 23, 2019, SAFE issued the statistics of current account foreign currency

        Our PRC subsidiaries' distributions to the offshore parentinterpretation and their carrying out cross-border foreign exchange activitiesimplementation in practice are still subject to the various SAFE registration requirements described above.

Share Option Rules

        Under the Administration Measures on Individual Foreign Exchange Control issued by the People's Bank of China on December 25, 2006, all foreign exchange matters involved in employee share ownership plans and share option plans in which PRC citizens participate require approval from SAFE or its authorized branch. In addition, under the Notices on Issues concerning the Foreign Exchange Administration for Domestic Individuals Participating in Share Incentive Plans of Overseas Publicly-Listed Companies, or Share Option Rules, issued by the SAFE on February 15, 2012, PRC residents who are granted shares or share options by companies listed on overseas stock exchanges under share incentive plans are requiredsubstantial uncertainty.

Regulations Relating to (1) register with the SAFE or its local branches; (2) retain a qualified PRC agent, which may be a PRC subsidiary of the overseas listed company or another qualified institution selected by the PRC subsidiary, to conduct the SAFE registration and other procedures with respect to the share incentive plans on behalf of the participants; and (3) retain an overseas institution to handle matters in connection with their exercise of share options, purchase and sale of shares or interests and funds transfers.

Regulation of Dividend Distribution

Distributions

The principal laws, rules and regulations governing dividend distributiondistributions by foreign-invested enterprisescompanies in the PRC are the PRC Company Law, of the PRC, as amended, the Wholly Foreign-owned EnterpriseForeign Investment Law and its implementation regulations, and the Equity Joint Venture Law and its implementation regulations.Implementing Rules. Under these laws, rules and regulations,requirements, foreign-invested enterprisescompanies may pay dividends only out of their accumulated profit, if any, as determined in accordance with PRC accounting standards and regulations. Both PRC domestic companies and wholly-foreign ownedforeign invested PRC enterprisescompanies are required to allocate at least 10% of their respective accumulated after-tax profits each year, if any, to fund certain capital reserve funds until the aggregate amount of these reserve funds have reached 50% of the registered capital of the enterprises.companies. A PRC company is not permitted to distribute any profits until any losses from prior fiscal years have been offset. Profits retained from prior fiscal years may be distributed together with distributable profits from the current fiscal year.

Labor Laws and Social Insurance

Pursuant to the PRC Labor Law and the PRC Labor Contract Law, employers must execute written labor contracts with full-time employees. All employers must comply with local minimum wage standards. Employers must establish a comprehensive management system to protect the rights of their employees, including a system governing occupational health and safety to provide employees with occupational training to prevent occupational injury, and employers are required to truthfully inform prospective employees of the job description, working conditions, location, occupational hazards and status of safe production as well as remuneration and other conditions. Violations of the PRC Labor Contract Law and the PRC Labor Law may result in the imposition of fines and other administrative and criminal liability in the case of serious violations.

In addition, according to the PRC Social Insurance Law, employers like our PRC subsidiaries in China must provide employees with welfare schemes covering pension insurance, unemployment insurance, maternity insurance, work-related injury insurance, medical insurance and housing funds.

These payments are made to local administrative authorities, and any employer who fails to contribute may be fined and ordered to pay the deficit amount within a stipulated time limit.

Rest of the World Regulation

For other countries besidesoutside of the United States and the PRC, the requirements governing the conduct of clinical trials, drug licensing, pricing and reimbursement vary from country to country. In all cases the clinical trials must be conducted in accordance with GCP requirements and the applicable regulatory requirements and the ethical principles having their origin in the Declaration of Helsinki.

        If we fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things, fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.

Manufacturing and Supply

        We lease an approximately 140 square meter manufacturing facility in Beijing, China, which produces and supplies preclinical and clinical trial materials for some of our small molecule drug candidates. In addition, we lease an approximately 11,000 square meter space and are building a manufacturing facility in Suzhou, China, where we intend to produce drug candidates for clinical or, in the future, commercial use. This facility consists of one oral-solid-dosage production line for small molecule drug products and one pilot plant for monoclonal antibody drug substances. We also outsource to a limited number of external service providers the production of some drug substances and drug products, and we expect to continue to do so to meet the preclinical and clinical requirements of our drug candidates. We have framework agreements with most of our external service providers, under which they generally provide services to us on a short-term and project-by-project basis.

        On March 7, 2017, BeiGene (Hong Kong) Co., Limited, our wholly owned subsidiary, entered into a definitive agreement with Guangzhou Development District and its affiliate Guangzhou GET Technology Development Co., Ltd to establish a commercial-scale biologics manufacturing facility in Guangzhou, Guangdong Province, China. We expect to acquire at least 100,000 square meters of land for the manufacturing facility for biologics production. The joint venture will also provide funding for research and development of biologic drug candidates in China. See "Part IV—Item 15—Exhibits, Financial Statement Schedules—Note 22. Subsequent Events" for additional information.

        Currently, we obtain raw materials for our manufacturing activities from multiple suppliers who we believe have sufficient capacity to meet our demands. In addition, we believe that adequate alternative sources for such supplies exist. However, a risk exists that an interruption supplies would materially harm our business. We typically order raw materials and services on a purchase order basis and do not enter into long-term dedicated capacity or minimum supply arrangements.

        Manufacturing is subject to extensive regulations that impose various procedural and documentation requirements governing record keeping, manufacturing processes and controls, personnel, quality control and quality assurance, among others. Our manufacturing facilities and the contract manufacturing organizations we use to manufacture our drug candidates operate under cGMP conditions. cGMP are regulatory requirements for the production of pharmaceuticals that will be used in humans. For most of our manufacturing processes a back-up cGMP manufacturer is in place or can easily be identified.

Employees

ATM


Means ataxia telangiectasia mutated, a serine/threonine protein kinase that plays a critical role in response to DNA damage.

BRAF


Means a human gene that makes the B-raf protein involved in sending internal cell signals that direct cell growth. In cells expressing mutant BRAF V600E and in conditions of low RAS-GTP, all RAF isoforms exist predominantly as monomers. However, unlike wild-type RAFs, monomeric BRAF V600E is hyperactive. Under conditions where RAS is activated or other BRAF induced resistance, RAF isoforms form dimers (two copies of RAF proteins bind together).

B-cell


Means a type of white blood cell that differs from other lymphocytes like T-cells by the presence of the BCR on the B-cell's outer surface.

BCR


Means B-cell receptor, a specialized receptor protein that allows a B-cell to bind to specific antigens.

BID


Meansbis in die or "twice daily," the frequency that a medical prescription or drug is taken by a patient.

BRCA


Means breast cancer susceptibility gene, of which there are two (BRCA1 and BRCA2). BRCA proteins are key components of homologous recombination DNA repair pathway. BRCA deleterious mutations are associated with breast and ovarian cancers.

BTK


Means Bruton's tyrosine kinase. BTK is a key component of the BCR signaling pathway and is an important regulator of cell proliferation and cell survival in various lymphomas.

CD20


Means B-lymphocyte antigen CD20, a B-cell specific cell-surface molecule that is encoded by the MS4A1 gene.

CTLA-4


Means cytotoxic T-lymphocyte-associated protein 4, a protein receptor that functions as an immune checkpoint and downregulates the immune system. CTLA-4 is found on the surface of T-cells.

DNA


Means deoxyribonucleic acid, a self-replicating molecule that carries genetic information and is present in almost all living organisms.

EGFR


Means epidermal growth factor receptor. EGFR is a cell surface protein that binds to epidermal growth factor, and mutations in this gene are associated with lung cancer.

ERK


Means extracellular signal-regulated kinase, which is a downstream signaling molecule of the MAPK pathway.

FcgRIMeans Fc gamma receptor I, a receptor that binds the most common class of antibody, Immunoglobulin G, or IgG, including IgG1, IgG3 and IgG4. FcgRI is expressed in certain human immune cells including monocytes, macrophages and dendritic cells and may function to activate these immune cells. FcgRI has the highest affinity to IgGs among the members of the Fc gamma receptor family.

GTPase


Means a large family of hydrolase enzymes that can bind and hydrolyze guanosine triphosphate.

Hemoglobin


Means the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs.

HER2


Means human epidermal growth factor receptor 2, also known as receptor tyrosine-protein kinase erbB-2. HER2 is a member of the human epidermal growth factor receptor (HER/EGFR/ERBB) family. Amplification or overexpression of this oncogene is associated with certain aggressive types of breast cancer.

HRAS


Means GTPase Hras, also known as transforming protein p21, an enzyme that is encoded in humans by the HRAS gene.

Immunoglobulin


Means glycoprotein molecules produced by plasma cells (white blood cells), which are also known as antibodies. They act as a critical part of the immune response by specifically recognizing and binding to particular antigens, such as bacteria or viruses, and aiding in their destruction.

IgM


Means Immunoglobulin M, a basic antibody that is produced by B-cells found mainly in the blood and lymph fluid.

ITK


Means interleukin-2-inducible T-cell kinase, a tyrosine-protein kinase that is encoded in humans by the ITK gene and is highly expressed in T-cells.

JAK3


Means tyrosine-protein Janus kinase 3, a non-receptor tyrosine kinase involved in various processes including cell growth, development, or differentiation.

Kinase


Means a type of enzyme that catalyzes the transfer of phosphate groups from high-energy, phosphate-donating molecules to specific substrates. The protein kinases make up the majority of all kinases. Protein kinases act on proteins, phosphorylating them on their serine, threonine, tyrosine, or histidine residues. These kinases play a major role in protein and enzyme regulation as well as signaling in the cell.

KRAS


KRAS is known as V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog. It is an oncogene that is often mutated in a number of cancers. The protein product of the normal KRAS gene performs an essential function in normal tissue signaling, and the mutation of a KRAS gene is an essential step in the development of many cancers.

Lesion


Means almost any abnormal change involving any biological structure, tissue or organ due to disease or injury, similar in meaning to the word "damage."

MAPKMeans mitogen-activated protein kinase. The MAPK pathway is a chain of proteins in the cell that communicates a signal from a receptor on the cell surface to the DNA in the nucleus of the cell. This pathway includes a small G protein (RAS) and three protein kinases (RAF, MEK, and ERK) and plays an essential role in regulating cell proliferation and survival.

MEK


Means mitogen/extracellular signal-regulated kinase, a member of the MAPK signaling cascade that is activated in melanoma.

NRAS


Means neuroblastoma RAS viral (V-Ras) oncogene homolog. It is also a member of RAS gene family. Similar to KRAS, it plays a role in many cancers and the mutation of an NRAS gene involves in the formation and growth of many cancers.

PAR


Means poly ADP ribose. PAR chains are synthesized by Poly(ADP-ribose) polymerases on various nuclear protein acceptors usually involved in DNA replication, transcription and repair pathways.

PARP


Means poly ADP ribose polymerase, a family of proteins involved in numerous cellular processes, mostly involving DNA replication and transcriptional regulation, which plays an essential role in cell survival in response to DNA damage.

PBMC


Means a peripheral blood mononuclear cell, any blood cell that has a round, as opposed to a lobed, nucleus (e.g., a lymphocyte, monocyte, or macrophage, all types of white blood cells).

PD-1


Means programmed cell death protein 1, an immune checkpoint receptor expressed on T-cells and pro-B-cells that binds two ligands, PD-L1 and PD-L2. PD-1 is a cell



surface receptor that plays an important role in down-regulating the immune system by preventing the activation of T-cells.

PD-L1


Means programmed death-ligand 1, a protein in humans encoded by the CD274 gene. PD-L1 binds the PD-1 receptor and sends an inhibitory signal inside the T-cell, stopping it from making more poisonous proteins and killing the cells that send the signal via PD-L1 and in the neighborhood.

PDX


Means patient-derived xenograft, created when the cancerous tissue from a human patient's primary tumor is implanted directly into an immunodeficient mouse.

pERK


Means phosphorylated extracellular signal-regulated kinase, which is a modified form of the ERK protein (a downstream signaling molecule of the MAPK pathway).

QD


Meansquaque die or "every day," the frequency that a medical prescription or drug is taken by a patient.

RAF


Means Rapidly Accelerated Fibrosarcoma. RAF kinases are a family of three serine/threonine-specific protein kinases that are related to retroviral oncogenes. RAF kinases participate in the RAS-RAF-MEK-ERK MAPK pathway.

RAF dimerMeans a protein complex formed by two copies of RAF proteins. This could be a BRAF-BRAF complex, a BRAF-CRAF complex, or a CRAF-CRAF complex.

Signaling cascade


Means a signal transduction pathway between cells where each signal transduction occurs with a primary extracellular messenger that binds to a receptor and initiates intracellular signals (i.e. molecule A activates several molecule Bs, which then in turn activate several molecule Cs).

T-cell


Means a type of white blood cell that play a large role in immune response and that differs from other white blood cells like B-cells by the presence of the T-cell receptor on the T-cell's outer surface, which is responsible for recognizing antigens bound to major histocompatibility complex molecules.

TEC


Means tyrosine-protein kinase Tec, an enzyme in humans encoded by the TEC gene. The Tec kinase is an integral component of T-cell signaling and has a distinct role in T-cell activation.

TIM-3


Means T-cell immunoglobulin and mucin-domain containing-3, a Th1-specific cell surface protein that functions as an immune checkpoint, regulating macrophage activation and enhancing the severity of experimental autoimmune encephalomyelitis in mice.

Xenograft


Means the cells, tissues or organs of one species transplanted into another species.

Item 1A. Risk Factors

The following section includes the most significant factors that we believe may adversely affect our business and operations. You should carefully consider the risks and uncertainties described below and all information contained in this Annual Report, including our financial statements and the related notes and "Part II—Item 7—Management's“Part II-Item 7-Management’s Discussion and Analysis of Financial Condition and Results of Operations," before deciding to invest in the ADSs.our ADSs or ordinary shares. The occurrence of any of the events or developments described below could harm our business, financial condition, results of operations and growth prospects. In such an event, the market price of theour ADSs and ordinary shares could decline, and you may lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impair our business operations

Risks Related to Our Financial Position and Need for Additional Capital

We are a globally focused biopharmaceutical company and have a limited operating history, which may make it difficult to evaluate our current business and predict our future performance.

        We are a globally focused biopharmaceutical company formed in October 2010. Our operations to date have focused on organizing and staffing our company, business planning, raising capital, establishing our intellectual property portfolio and conducting preclinical studies and clinical trials of our current drug candidates, such as BGB-3111, BGB-A317, BGB-290 and BGB-283. We have not yet demonstrated an ability to initiate or successfully complete large-scale, pivotal clinical trials, obtain regulatory approvals, manufacture a commercial scale drug, or arrange for a third party to do so on our behalf, or conduct sales and marketing activities necessary for successful commercialization. We have not yet obtained regulatory approval for, or demonstrated an ability to commercialize, any of our drug candidates. We have no products approved for commercial sale and have not generated any revenue from product sales. Consequently, any predictions you make about our future success or viability may not be as accurate as they could be if we had a longer operating history. In addition, as a new business, we may encounter unforeseen expenses, difficulties, complications, delays and other known and unknown factors.

        We are focused on the discovery and development of innovative, molecularly targeted and immuno-oncology drugs for the treatment of cancers. Our limited operating history, particularly in light of the rapidly evolving cancer treatment field, may make it difficult to evaluate our current business and predict our future performance. Our short history makes any assessment of our future success or viability subject to significant uncertainty. We will encounter risks and difficulties frequently experienced by early-stage companies in rapidly evolving fields as we seek to transition to a company capable of supporting commercial activities. If we do not address these risks and difficulties successfully, our business will suffer.

We have incurred net losses in each period since our inception and anticipate that we will continue to incur net losses for the foreseeable future.

        Investment in pharmaceutical product development is highly speculative because it entails substantial upfront capital expenditures and significant risk that a drug candidate will fail to gain regulatory approval or become commercially viable. We have devoted most of our financial resources to research and development, including our nonclinical development activities and clinical trials. We have not generated any revenue from product sales to date, and we continue to incur significant development and other expenses related to our ongoing operations. As a result, we are not profitable and have incurred losses in each period since our inception in 2010. We reported a net loss of $119.2 million, $57.1 million and $18.5 million, respectively, for the years ended December 31, 2016, 2015 and 2014. As of December 31, 2016, we had a deficit accumulated of $237.4 million. Substantially


all of our operating losses have resulted from costs incurred in connection with our research and development programs and from general and administrative costs associated with our operations.

        We expect to continue to incur losses for the foreseeable future, and we expect these losses to increase as we continue our development of, and seek regulatory approvals for, our drug candidates, and begin to commercialize approved drugs, if any. Typically, it takes many years to develop one new drug from the time it is discovered to when it is available for treating patients. We may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect our business. The size of our future net losses will depend, in part, on the rate of future growth of our expenses, our ability to generate revenues and the timing and amount of milestones and other required payments to third parties in connection with our potential future arrangements with third parties. If any of our drug candidates fail in clinical trials or do not gain regulatory approval, or if approved, fail to achieve market acceptance, we may never become profitable. Even if we achieve profitability in the future, we may not be able to sustain profitability in subsequent periods. Our prior losses and expected future losses have had, and will continue to have, an adverse effect on our shareholders' equity and working capital.

        We expect our research and development expenses to continue to be significant in connection with our continued investment in our cancer biology platform and our ongoing and planned clinical trials for our drug candidates, such as BGB-3111, BGB-A317, BGB-290 and BGB-283. Furthermore, if we obtain regulatory approval for our drug candidates, we expect to incur increased sales and marketing expenses. In addition, we will incur additional costs associated with operating as a public company. As a result, we expect to continue to incur significant and increasing operating losses and negative cash flows for the foreseeable future. These losses have had and will continue to have a material adverse effect on our shareholders' deficit, financial position, cash flows and working capital.

We currently do not generate revenue from product sales and may never become profitable.

        Our ability to generate revenue and become profitable depends upon our ability to successfully complete the development of, and obtain the necessary regulatory approvals for, our drug candidates, such as BGB-3111, BGB-A317, BGB-290 and BGB-283, as we do not currently have any drugs that are available for commercial sale. We expect to continue to incur substantial and increasing losses through the projected commercialization of our drug candidates. None of our drug candidates have been approved for marketing in the United States, the European Union, the People's Republic of China, or PRC, or any other jurisdiction and may never receive such approval. Our ability to achieve revenue and profitability is dependent on our ability to complete the development of our drug candidates, obtain necessary regulatory approvals, and have our drugs manufactured and successfully marketed.

        Even if we receive regulatory approval of our drug candidates for commercial sale, we do not know when they will generate revenue, if at all. Our ability to generate product sales revenue depends on a number of factors, including our ability to continue:


        In addition, because of the numerous risks and uncertainties associated with drug development, we are unable to predict the timing or amount of increased expenses, or when, or if, we will be able to achieve or maintain profitability. In addition, our expenses could increase beyond expectations if we are required by the FDA; the CFDA; the EMA; or other comparable regulatory authorities to perform studies in addition to those that we currently anticipate. Even if our drug candidates are approved for commercial sale, we anticipate incurring significant costs associated with the commercial launch of these drugs.

        Our ability to become and remain profitable depends on our ability to generate revenue. Even if we are able to generate revenues from the sale of our potential drugs, we may not become profitable and may need to obtain additional funding to continue operations. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be forced to reduce our operations. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable would decrease the value of our company and could impair our ability to raise capital, expand our business or continue our operations. Failure to become and remain profitable may adversely affect the market price of the ADSs and our ability to raise capital and continue operations.

We will need to obtain additional financing to fund our operations, and if we are unable to obtain such financing, we may be unable to complete the development and commercialization of our primary drug candidates.

        We have financed our operations with a combination of equity and debt offerings, contracts, and private and public grants. Through December 31, 2016, we raised approximately $170 million in private equity financing and $10 million in non-convertible debt financings. To date, we have received a total of $37 million in upfront payments and milestone payments through our collaboration arrangements with Merck KGaA, Darmstadt Germany for BGB-283 and BGB-290. On February 8, 2016 and November 23, 2016, we completed our initial public offering and follow-on public offering of the ADSs and received net proceeds of $166.2 million and $198.6 million, respectively, after deducting underwriting discount and offering expenses. Our drug candidates will require the completion of regulatory review, significant marketing efforts and substantial investment before they can provide us with any product sales revenue.

        Our operations have consumed substantial amounts of cash since inception. Our operating activities used $89.5 million, $39.8 million and $8.7 million of net cash during the years ended December 31, 2016, 2015 and 2014, respectively. We expect to continue to spend substantial amounts on drug discovery advancing the clinical development of our drug candidates, and launching and commercializing any drug candidates for which we receive regulatory approval, including building our own commercial organizations to address certain markets.


        We will need to obtain additional financing to fund our future operations, including completing the development and commercialization of our primary drug candidates: BGB-3111, BGB-A317, BGB-290 and BGB-283. We will need to obtain additional financing to conduct additional clinical trials for the approval of our drug candidates if requested by regulatory bodies, and completing the development of any additional drug candidates we might discover. Moreover, our fixed expenses such as rent, interest expense and other contractual commitments are substantial and are expected to increase in the future.

        Our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement and involves risks and uncertainties, and actual results could vary as a result of a number of factors, including the factors discussed elsewhere in this "Risk Factors" section. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect. Our future funding requirements will depend on many factors, including, but not limited to:

        Until we can generate a sufficient amount of revenue, we may finance future cash needs through public or private equity offerings, license agreements, debt financings, collaborations, strategic alliances and marketing or distribution arrangements. Additional funds may not be available when we need them on terms that are acceptable to us, or at all. General market conditions or the market price of the ADSs may not support capital raising transactions such as an additional public or private offering of


the ADSs or other securities. In addition, our ability to raise additional capital may be dependent upon the ADSs being quoted on the NASDAQ or upon obtaining shareholder approval. There can be no assurance that we will be able to satisfy the criteria for continued listing on the NASDAQ or that we will be able to obtain shareholder approval if it is necessary. If adequate funds are not available, we may be required to delay or reduce the scope of or eliminate one or more of our research or development programs or our commercialization efforts. We may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time. In addition, if we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams or drug candidates or to grant licenses on terms that may not be favorable to us.

        We believe that our existing cash and cash equivalents, will not be sufficient to enable us to complete all necessary global development or commercially launch our current drug candidates. Accordingly, we will require further funding through other public or private offerings, debt financing, collaboration and licensing arrangements or other sources. Adequate additional funding may not be available to us on acceptable terms, or at all. If we are unable to raise capital when needed or on attractive terms, we would be forced to delay, reduce or eliminate our research and development programs or future commercialization efforts. Our inability to obtain additional funding when we need it could seriously harm our business.

Raising additional capital may cause dilution to our shareholders, restrict our operations or require us to relinquish rights to our technologies or drug candidates.

        We may seek additional funding through a combination of equity offerings, debt financings, collaborations and licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms may include liquidation or other preferences that adversely affect your rights as a holder of the ADSs or our ordinary shares. The incurrence of additional indebtedness or the issuance of certain equity securities could result in increased fixed payment obligations and could also result in certain additional restrictive covenants, such as limitations on our ability to incur additional debt or issue additional equity, limitations on our ability to acquire or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. In addition, issuance of additional equity securities, or the possibility of such issuance, may cause the market price of the ADSs to decline. In the event that we enter into collaborations or licensing arrangements in order to raise capital, we may be required to accept unfavorable terms, including relinquishing or licensing to a third party on unfavorable terms our rights to technologies or drug candidates that we otherwise would seek to develop or commercialize ourselves or potentially reserve for future potential arrangements when we might be able to achieve more favorable terms.

Fluctuations in exchange rates could result in foreign currency exchange losses and could materially reduce the value of your investment.

        We incur portions of our expenses, and may in the future derive revenues, in currencies other than the U.S. dollar, in particular, the RMB and Australian dollars. As a result, we are exposed to foreign currency exchange risk as our results of operations and cash flows are subject to fluctuations in foreign currency exchange rates. For example, a significant portion of our clinical trial activities are conducted outside of the United States, and associated costs may be incurred in the local currency of the country in which the trial is being conducted, which costs could be subject to fluctuations in currency exchange rates. We currently do not engage in hedging transactions to protect against uncertainty in future exchange rates between particular foreign currencies and the U.S. dollar. A decline in the value of the U.S. dollar against currencies in countries in which we conduct clinical trials could have a negative


impact on our research and development costs. We cannot predict the impact of foreign currency fluctuations, and foreign currency fluctuations in the future may adversely affect our financial condition, results of operations and cash flows.

        The value of the RMB against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in political and economic conditions and the foreign exchange policy adopted by the PRC, Australia and other non-U.S. governments. Specifically in the PRC, on July 21, 2005, the PRC government changed its policy of pegging the value of the RMB to the U.S. dollar. Following the removal of the U.S. dollar peg, the RMB appreciated more than 20% against the U.S. dollar over the following three years. Between July 2008 and June 2010, this appreciation halted and the exchange rate between the RMB and the U.S. dollar remained within a narrow band. Since June 2010, the PRC government has allowed the RMB to appreciate slowly against the U.S. dollar again, and it has appreciated more than 10% since June 2010. In April 2012, the PRC government announced that it would allow more RMB exchange rate fluctuation. On August 11, 2015, China's central bank executed a 2% devaluation in the RMB. Over the following two days, Chinese currency fell 3.5% against the dollar. However, it remains unclear what further fluctuations may occur or what impact this will have on the currency.

        It is difficult to predict how market forces or PRC, Australian, U.S. or other government policies may impact the exchange rate between the Australian dollar, RMB, U.S. dollar and other currencies in the future. There remains significant international pressure on the PRC government to adopt a more flexible currency policy, which could result in greater fluctuation of the RMB against the U.S. dollar. Substantially all of our revenues are denominated in U.S. dollars and our costs are denominated in U.S. dollars, Australian dollars and RMB, and a large portion of our financial assets and a significant portion of our debt is denominated in U.S. dollars. Any significant revaluation of the RMB may materially reduce any dividends payable on the ADSs in U.S. dollars. To the extent that we need to convert U.S. dollars we received from our initial public offering and follow-on public offering into RMB for our operations, appreciation of the RMB against the U.S. dollar would have an adverse effect on the RMB amount we would receive. Conversely, if we decide to convert our RMB into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or ADSs or for other business purposes, appreciation of the U.S. dollar against the RMB would have a negative effect on the U.S. dollar amount we would receive.

Our investments are subject to risks that could result in losses.

        We had cash and cash equivalents of $87.5 million, $17.9 million and $13.9 million and short-term investments of $280.7 million, $82.6 million and $30.5 million at December 31, 2016, 2015 and 2014, respectively. At December 31, 2016, our short-term investments mainly consisted of U.S. Treasury securities. On February 8, 2016 and November 23, 2016, we completed our initial public offering and follow-on public offering of the ADSs and received net proceeds of $166.2 million and $198.6 million, respectively, after deducting underwriting discount and offering expenses. We may invest our cash in a variety of financial instruments, principally securities issued by the U.S. government and its agencies, investment grade corporate bonds, including commercial paper and money market instruments, which may not yield a favorable return to our shareholders. All of these investments are subject to credit, liquidity, market and interest rate risk. Such risks, including the failure or severe financial distress of the financial institutions that hold our cash, cash equivalents and investments, may result in a loss of liquidity, impairment to our investments, realization of substantial future losses, or a complete loss of the investments in the long-term, which may have a material adverse effect on our business, results of operations, liquidity and financial condition. Our primary exposure to market risk relates to fluctuations in the interest rates of the PRC and the United States. In order to manage the risk to our investments, we maintain an investment policy that, among other things, limits the amount that we may invest in any one issue or any single issuer and requires us to only invest in high credit quality securities. While we


believe our cash and cash equivalents do not contain excessive risk, we cannot provide absolute assurance that in the future investments will not be subject to adverse changes in market value.

Risks Related to Clinical Development of Our Drug Candidates

We depend substantially on the success of our drug candidates, particularly BGB-3111, BGB-A317, BGB-290 and BGB-283, which are in clinical development. Clinical trials of our drug candidates may not be successful. If we are unable to commercialize our drug candidates, or experience significant delays in doing so, our business will be materially harmed.

        Our business and the ability to generate revenue related to product sales, if ever, will depend on the successful development, regulatory approval and commercialization of our drug candidates for the treatment of patients with cancer, particularly BGB-3111, BGB-A317, BGB-290 and BGB-283, which are still in development, and other drugs we may develop. We have invested a significant portion of our efforts and financial resources in the development of our existing drug candidates. The success of our drug candidates, including BGB-3111, BGB-A317, BGB-290 and BGB-283, will depend on several factors, including:

        If we do not achieve one or more of these factors in a timely manner or at all, we could experience significant delays in our ability to obtain approval for and/or to successfully commercialize our drug candidates, which would materially harm our business and we may not be able to generate sufficient revenues and cash flows to continue our operations.

We may not be successful in our efforts to identify or discover additional drug candidates. Due to our limited resources and access to capital, we must and have in the past decided to prioritize development of certain drug candidates; these decisions may prove to have been wrong and may adversely affect our business.

        Although we intend to explore other therapeutic opportunities with our cancer biology platform in addition to the drug candidates that we are currently developing, we may fail to identify other drug


candidates for clinical development for a number of reasons. For example, our research methodology may be unsuccessful in identifying potential drug candidates or those we identify may be shown to have harmful side effects or other characteristics that make them unmarketable or unlikely to receive regulatory approval. Specifically, we have focused on developing our cancer biology platform, which enables us to test a large panel of tumor models for sensitivity to the drug candidates we generated, identify targets to pursue, identify drug-resistance mechanisms, explore combination strategies and regimens, and improve our understanding of the contributions of tumor micro, or macro-environment in cancer treatments. If our cancer biology platform fails to identify potential drug candidates, our business could be materially harmed.

        Research programs to pursue the development of our drug candidates for additional indications and to identify new drug candidates and disease targets require substantial technical, financial and human resources whether or not we ultimately are successful. Our research programs may initially show promise in identifying potential indications and/or drug candidates, yet fail to yield results for clinical development for a number of reasons, including:

        Because we have limited financial and managerial resources, we focus on research programs and drug candidates for specific indications. As a result, we may forego or delay pursuit of opportunities with other drug candidates or for other indications that later prove to have greater commercial potential or a greater likelihood of success. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities.

        Accordingly, there can be no assurance that we will ever be able to identify additional therapeutic opportunities for our drug candidates or to develop suitable potential drug candidates through internal research programs, which could materially adversely affect our future growth and prospects. We may focus our efforts and resources on potential drug candidates or other potential programs that ultimately prove to be unsuccessful.

If we encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed or otherwise adversely affected.

        The timely completion of clinical trials in accordance with their protocols depends, among other things, on our ability to enroll a sufficient number of patients who remain in the trial until its conclusion. We may experience difficulties in patient enrollment in our clinical trials for a variety of reasons, including:


        In addition, our clinical trials will compete with other clinical trials for drug candidates that are in the same therapeutic areas as our drug candidates, such as BGB-3111, BGB-A317, BGB-290 and BGB-283, and this competition will reduce the number and types of patients available to us, because some patients who might have opted to enroll in our trials may instead opt to enroll in a trial being conducted by one of our competitors. Because the number of qualified clinical investigators is limited, we expect to conduct some of our clinical trials at the same clinical trial sites that some of our competitors use, which will reduce the number of patients who are available for our clinical trials at such clinical trial sites.

        Even if we are able to enroll a sufficient number of patients in our clinical trials, delays in patient enrollment may result in increased costs or may affect the timing or outcome of the planned clinical trials, which could prevent completion of these trials and adversely affect our ability to advance the development of our drug candidates.

Some of our drug candidates represent a novel approach to cancer treatment that could result in delays in clinical development, heightened regulatory scrutiny, or delays in our ability to achieve regulatory approval or commercialization of our drug candidates.

        Some of our drug candidates represent a departure from more commonly used methods for cancer treatment, and therefore represent a novel approach that carries inherent development risks. The need to further develop or modify in any way the protocols related to our drug candidates to demonstrate safety or efficacy may delay the clinical program, regulatory approval or commercialization, if approved. In addition, potential patients and their doctors may be inclined to use conventional standard-of-care treatments rather than enroll patients in any future clinical trial. This may have a material impact on our ability to generate revenues from our drug candidates. Further, given the novelty of our drug candidates, the end users and medical personnel may require a substantial amount of education and training.

Clinical drug development involves a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be predictive of future trial results.

        Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the clinical trial process. The results of preclinical studies and early clinical trials of our drug candidates may not be predictive of the results of later-stage clinical trials. Drug candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical trials. In some instances, there can be significant variability in safety and/or efficacy results between different trials of the same drug candidate due to numerous factors, including changes in trial procedures set forth in protocols, differences in the size and type of the patient populations, including genetic differences, patient adherence to the dosing regimen and other trial protocols and the rate of dropout among


clinical trial participants. In the case of any trials we conduct, results may differ from earlier trials due to the larger number of clinical trial sites and additional countries and languages involved in such trials. A number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in advanced clinical trials due to lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier trials. Our future clinical trial results may not be favorable.

If clinical trials of our drug candidates fail to demonstrate safety and efficacy to the satisfaction of the FDA, CFDA, EMA or other comparable regulatory authorities or do not otherwise produce positive results, we may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our drug candidates.

        Before obtaining regulatory approval for the sale of our drug candidates, such as BGB-3111, BGB-A317, BGB-290 and BGB-283, we must conduct extensive clinical trials to demonstrate the safety and efficacy of our drug candidates in humans. Clinical testing is expensive, difficult to design and implement, can take many years to complete and is uncertain as to outcome. A failure of one or more of our clinical trials can occur at any stage of testing. The outcome of preclinical testing and early clinical trials may not be predictive of the success of later clinical trials, and successful interim results of a clinical trial do not necessarily predict successful final results.

        We may experience numerous unexpected events during, or as a result of, clinical trials that could delay or prevent our ability to receive regulatory approval or commercialize our drug candidates, including:


        If we are required to conduct additional clinical trials or other testing of our drug candidates beyond those that we currently contemplate, if we are unable to successfully complete clinical trials of our drug candidates or other testing, if the results of these trials or tests are not positive or are only modestly positive or if they raise safety concerns, we may:

        Delays in testing or approvals may result in increases in our drug development costs. We do not know whether any clinical trials will begin as planned, will need to be restructured or will be completed on schedule, or at all.

        Significant clinical trial delays also could shorten any periods during which we have the exclusive right to commercialize our drug candidates or allow our competitors to bring drugs to market before we do and impair our ability to commercialize our drug candidates and may harm our business and results of operations.

Risks Related to Obtaining Regulatory Approval for Our Drug Candidates

The regulatory approval processes of the FDA, CFDA, EMA and other comparable regulatory authorities are lengthy, time consuming and inherently unpredictable, and if we are ultimately unable to obtain regulatory approval for our drug candidates, our business will be substantially harmed.

        The time required to obtain approval by the FDA, CFDA, EMA and other comparable regulatory authorities is unpredictable but typically takes many years following the commencement of preclinical studies and clinical trials and depends upon numerous factors, including the substantial discretion of the regulatory authorities. In addition, approval policies, regulations or the type and amount of clinical data necessary to gain approval may change during the course of a drug candidate's clinical development and may vary among jurisdictions. We have not obtained regulatory approval for any drug candidate, and it is possible that none of our existing drug candidates or any drug candidates we may discover, in-license or acquire and seek to develop in the future will ever obtain regulatory approval.

        Our drug candidates could fail to receive regulatory approval from the FDA, CFDA, EMA or a comparable regulatory authority for many reasons, including:


        The FDA, CFDA, EMA or a comparable regulatory authority may require more information, including additional preclinical or clinical data, to support approval, which may delay or prevent approval and our commercialization plans, or we may decide to abandon the development program. If we were to obtain approval, regulatory authorities may approve any of our drug candidates for fewer or more limited indications than we request, may grant approval contingent on the performance of costly post-marketing clinical trials, or may approve a drug candidate with a label that is not desirable for the successful commercialization of that drug candidate. In addition, if our drug candidate produces undesirable side effects or safety issues, the FDA may require the establishment of a Risk Evaluation Mitigation Strategy, or REMS, or the CFDA, EMA or a comparable regulatory authority may require the establishment of a similar strategy, that may, for instance, restrict distribution of our drugs and impose burdensome implementation requirements on us. Any of the foregoing scenarios could materially harm the commercial prospects of our drug candidates.

Regulatory approval may be substantially delayed or may not be obtained for one or all of our drug candidates if regulatory authorities require additional time or studies to assess the safety and efficacy of our drug candidates.

        We may be unable to initiate or complete development of our drug candidates, such as BGB-3111, BGB-A317, BGB-290 and BGB-283, on schedule, if at all. The timing for the completion of the studies for our drug candidates will require funding beyond the proceeds of our initial public offering and follow-on public offering. In addition, if regulatory authorities require additional time or studies to assess the safety or efficacy of our drug candidates, we may not have or be able to obtain adequate funding to complete the necessary steps for approval for any or all of our drug candidates. Preclinical studies and clinical trials required to demonstrate the safety and efficacy of our drug candidates are time consuming and expensive and together take several years or more to complete. Delays in clinical trials, regulatory approvals or rejections of applications for regulatory approval in the United States, Australia, New Zealand, the PRC, Europe or other markets may result from many factors, including:


        Changes in regulatory requirements and guidance may also occur, and we may need to amend clinical trial protocols submitted to applicable regulatory authorities to reflect these changes. Amendments may require us to resubmit clinical trial protocols to IRBs or ethics committees for re-examination, which may impact the costs, timing or successful completion of a clinical trial.

        If we experience delays in the completion of, or the termination of, a clinical trial, of any of our drug candidates, the commercial prospects of our drug candidates will be harmed, and our ability to generate product sales revenues from any of those drug candidates will be delayed. In addition, any delays in completing our clinical trials will increase our costs, slow down our drug candidate development and approval process, and jeopardize our ability to commence product sales and generate revenues. Any of these occurrences may harm our business, financial condition and prospects


significantly. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our drug candidates.

        If we are required to conduct additional clinical trials or other studies with respect to any of our drug candidates beyond those that we initially contemplated, if we are unable to successfully complete our clinical trials or other studies or if the results of these studies are not positive or are only modestly positive, we may be delayed in obtaining regulatory approval for that drug candidate, we may not be able to obtain regulatory approval at all or we may obtain approval for indications that are not as broad as intended. Our drug development costs will also increase if we experience delays in testing or approvals, and we may not have sufficient funding to complete the testing and approval process. Significant clinical trial delays could allow our competitors to bring drugs to market before we do and impair our ability to commercialize our drugs, if and when approved. If any of this occurs, our business will be materially harmed.

Failure to successfully validate, develop and obtain regulatory approval for companion diagnostics could harm our drug development strategy.

        As one of the key elements of our clinical development strategy, we seek to identify patient subsets within a disease category who may derive selective and meaningful benefit from the drug candidates we are developing. In collaboration with partners, we plan to develop companion diagnostics to help us to more accurately identify patients within a particular subset, both during our clinical trials and in connection with the commercialization of our drug candidates. Companion diagnostics are subject to regulation by the FDA, CFDA, EMA and other comparable regulatory authorities and require separate regulatory approval or clearance prior to commercialization. We do not develop companion diagnostics internally, and thus we are dependent on the sustained cooperation and effort of our third-party collaborators in developing and obtaining approval or clearance for these companion diagnostics. We and our collaborators may encounter difficulties in developing and obtaining approval or clearance of the companion diagnostics, including issues relating to selectivity/specificity, analytical validation, reproducibility or clinical validation. Any delay or failure by our collaborators to develop or obtain regulatory approval or clearance of the companion diagnostics could delay or prevent approval of our drug candidates. In addition, our collaborators may encounter production difficulties that could constrain the supply of the companion diagnostics, and both they and we may have difficulties gaining acceptance of the use of the companion diagnostics in the clinical community. A failure of such companion diagnostics to gain market acceptance would have an adverse effect on our ability to derive revenues from sales of our drugs. In addition, the diagnostic company with whom we contract may decide to discontinue selling or manufacturing the diagnostic we anticipate using in connection with development and commercialization of our drug candidates or our relationship with such diagnostic company may otherwise terminate. We may not be able to enter into arrangements with another diagnostic company to obtain supplies of an alternative diagnostic test for use in connection with the development and commercialization of our drug candidates or do so on commercially reasonable terms, which could adversely affect and/or delay the development or commercialization of our drug candidates.

Our drug candidates may cause undesirable adverse events or have other properties that could delay or prevent their regulatory approval, limit the commercial profile of an approved label, or result in significant negative consequences following any regulatory approval.

        Undesirable AEs caused by our drug candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA, CFDA, EMA or other comparable regulatory authority. Results of our trials could reveal a high and unacceptable severity or prevalence of AEs. In such an event, our


trials could be suspended or terminated and the FDA, CFDA, EMA or other comparable regulatory authorities could order us to cease further development of, or deny approval of, our drug candidates for any or all targeted indications. Undesirable AEs caused by BGB-3111 may include, but are not limited to, neutropenia, petechiae (spots that appear on the skin as a result of bleeding), purpura (subcutaneous bleeding), bruising, rash, peripheral neuropathy, and fatigue. Undesirable AEs caused by BGB-290 may include, but are not limited to, nausea, vomiting, diarrhea, lethargy, neutropenia, anemia, thrombocytopena, hypophosphataemia, and hot flush. Undesirable AEs caused by BGB-283 may include, but are not limited to, thrombocytopenia, fatigue, rash, hand-foot syndrome, hypertension, and anorexia. Drug-related AEs could affect patient recruitment or the ability of enrolled subjects to complete the trial, and could result in potential product liability claims. Any of these occurrences may harm our reputation, business, financial condition and prospects significantly.

        Additionally if one or more of our drug candidates receives regulatory approval, and we or others later identify undesirable side effects caused by such drugs, a number of potentially significant negative consequences could result, including:

        Any of these events could prevent us from achieving or maintaining market acceptance of the particular drug candidate, if approved, and could significantly harm our business, results of operations and prospects.

        Further, combination therapy, such as using our wholly-owned drug candidates as well as third-party agents, involves unique AEs that could be exacerbated compared to AEs from monotherapies. These types of AEs could be caused by our drug candidates and could also cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA, CFDA, EMA or other comparable regulatory authority. Results of our trials could reveal a high and unacceptable severity or prevalence of AEs.

A Fast Track Designation by the FDA, even if granted for any of our drug candidates, may not lead to a faster development or regulatory review or approval process, and does not increase the likelihood that our drug candidates will receive regulatory approval.

        We do not currently have Fast Track Designation for any of our drug candidates but may seek such designation in the future. If a drug is intended for the treatment of a serious or life-threatening condition and the drug demonstrates the potential to address unmet medical needs for that condition, the drug sponsor may apply for FDA Fast Track Designation. The FDA has broad discretion whether or not to grant this designation. Even if we believe a particular drug candidate is eligible for this designation, we cannot assure you that the FDA would decide to grant it. Even if we do receive Fast Track Designation, we may not experience a faster development process, review or approval compared to conventional FDA procedures. The FDA may withdraw a Fast Track Designation if it believes that


the designation is no longer supported by data from our clinical development program. Many drugs that have received Fast Track Designation have failed to obtain approval from the FDA.

A Breakthrough Therapy Designation by the FDA, even if granted for any of our drug candidates, may not lead to a faster development or regulatory review or approval process, and does not increase the likelihood that our drug candidates will receive regulatory approval.

        We do not currently have Breakthrough Therapy Designation for any of our drug candidates but may seek it in the future. A Breakthrough Therapy is defined as a drug that is intended, alone or in combination with one or more other drugs, to treat a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. For drugs that have been designated as Breakthrough Therapies, interaction and communication between the FDA and the sponsor can help to identify the most efficient path for development.

        Designation as a Breakthrough Therapy is within the discretion of the FDA. Accordingly, even if we believe, after completing early clinical trials, that one of our drug candidates meets the criteria for designation as a Breakthrough Therapy, the FDA may disagree and instead decide not to grant that designation. In any event, the receipt of a Breakthrough Therapy designation for a drug candidate may not result in a faster development process, review or approval compared to drugs considered for approval under conventional FDA procedures and does not assure ultimate approval by the FDA. In addition, even if one or more of our drug candidates qualify as Breakthrough Therapies, the FDA may later decide that such drug candidates no longer meet the conditions for qualification.

We may seek orphan drug exclusivity for some of our drug candidates, and we may be unsuccessful.

        Regulatory authorities in some jurisdictions, including the United States and Europe, may designate drugs for relatively small patient populations as orphan drugs. Under the Orphan Drug Act, the FDA may designate a drug as an orphan drug if it is a drug intended to treat a rare disease or condition, which is generally defined as a disease with a patient population of fewer than 200,000 individuals in the United States, or that affects more than 200,000 individuals in the United States and for which there is no reasonable expectation that costs of research and development of the product for the indication can be recovered by sales of the product in the United States. BGB-3111 received orphan drug designation from the FDA for CLL, MCL and WM in 2016.

        Generally, if a drug with an orphan drug designation subsequently receives the first regulatory approval for the indication for which it has such designation, the drug is entitled to a period of marketing exclusivity, which precludes the FDA or EMA, from approving another marketing application for the same drug for the same indication during the period of exclusivity. The applicable period is seven years in the United States and 10 years in Europe. The European exclusivity period can be reduced to six years if a drug no longer meets the criteria for orphan drug designation or if the drug is sufficiently profitable so that market exclusivity is no longer justified. Orphan drug exclusivity may be lost if the FDA or the EMA determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the drug to meet the needs of patients with the rare disease or condition.

        Even if we obtain orphan drug exclusivity for a drug candidate, that exclusivity may not effectively protect the drug candidate from competition because different drugs can be approved for the same condition and the same drugs can be approved for a different condition but used off-label for any orphan indication we may obtain. Even after an orphan drug is approved, the FDA can subsequently approve a drug that is otherwise the same drug for the same condition if the FDA concludes that the


later drug is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care.

Even if we receive regulatory approval for our drug candidates, we will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense and we may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with our drug candidates.

        If our drug candidates are approved, they will be subject to ongoing regulatory requirements for manufacturing, labeling, packaging, storage, advertising, promotion, sampling, record-keeping, conduct of post-marketing studies, and submission of safety, efficacy, and other post-market information, including both federal and state requirements in the United States and requirements of comparable regulatory authorities.

        Manufacturers and manufacturers' facilities are required to comply with extensive FDA, CFDA, EMA and comparable regulatory authority, requirements, including, in the United States, ensuring that quality control and manufacturing procedures conform to cGMP regulations. As such, we and our contract manufacturers will be subject to continual review and inspections to assess compliance with cGMP and adherence to commitments made in any NDA or BLA, other marketing application, and previous responses to inspection observations. Accordingly, we and others with whom we work must continue to expend time, money and effort in all areas of regulatory compliance, including manufacturing, production and quality control.

        Any regulatory approvals that we receive for our drug candidates may be subject to limitations on the approved indicated uses for which the drug may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing testing, including Phase 4 clinical trials and surveillance to monitor the safety and efficacy of the drug candidate. The FDA may also require a REMS program as a condition of approval of our drug candidates, which could entail requirements for long-term patient follow-up, a medication guide, physician communication plans or additional elements to ensure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. In addition, if the FDA, CFDA, EMA or a comparable regulatory authority approves our drug candidates, we will have to comply with requirements including, for example, submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with cGMP and GCP, for any clinical trials that we conduct post-approval.

        The FDA may seek to impose a consent decree or withdraw marketing approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the drug reaches the market. Later discovery of previously unknown problems with our drug candidates, including AEs of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical studies to assess new safety risks; or imposition of distribution restrictions or other restrictions under a REMS program. Other potential consequences include, among other things:


        The FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Drugs may be promoted only for their approved indications and for use in accordance with the provisions of the approved label. The FDA, CFDA, EMA and other regulatory authorities actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant liability. The policies of the FDA, CFDA, EMA and of other regulatory authorities may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our drug candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any regulatory approval that we may have obtained and we may not achieve or sustain profitability.

        In addition, if we were able to obtain accelerated approval of any of our drug candidates, the FDA would require us to conduct a confirmatory study to verify the predicted clinical benefit and additional safety studies. Other comparable regulatory authorities outside the United States, such as the CFDA or EMA, may have similar requirements. The results from the confirmatory study may not support the clinical benefit, which would result in the approval being withdrawn. While operating under accelerated approval, we will be subject to certain restrictions that we would not be subject to upon receiving regular approval.

Risks Related to Commercialization of Our Drugs and Drug Candidates

If we are not able to obtain, or experience delays in obtaining, required regulatory approvals, we will not be able to commercialize our drug candidates, and our ability to generate revenue will be materially impaired.

        We currently do not have any drug candidates that have gained regulatory approval for sale in the United States, European Union, China or any other country, and we cannot guarantee that we will ever have marketable drugs.

Our business is substantially dependent on our ability to complete the development of, obtain regulatory approval for and successfully commercialize drug candidates in a timely manner. We cannot commercialize drug candidates without first obtaining regulatory approval to market each drug from the FDA, CFDA, EMA and comparable regulatory authorities. BGB-3111, BGB-A317, BGB-290 and BGB-283 are each currently undergoing clinical trials. We cannot predict whether these trials and future trials will be successful or whether regulators will agree with our conclusions regarding the preclinical studies and clinical trials we have conducted to date.

        Before obtaining regulatory approvals for the commercial sale of any drug candidate for a target indication, we must demonstrate in preclinical studies and well-controlled clinical trials, and, with respect to approval in the United States, to the satisfaction of the FDA, that the drug candidate is safe and effective for use for that target indication and that the manufacturing facilities, processes and controls are adequate. In the United States, we have not submitted an NDA or BLA for any of our drug candidates. An NDA or BLA must include extensive preclinical and clinical data and supporting information to establish, in the case of an NDA, the drug candidate's safety and effectiveness or, in the case of a BLA, safety, purity and potency for each desired indication. The NDA or BLA must also include significant information regarding the chemistry, manufacturing and controls for the drug. Obtaining approval of an NDA or BLA is a lengthy, expensive and uncertain process, and approval may not be obtained. If we submit an NDA or BLA to the FDA, the FDA decides whether to accept or reject the submission for filing. We cannot be certain that any submissions will be accepted for filing and review by the FDA.

        Regulatory authorities outside of the United States, such as the EMA or regulatory authorities in Australia and New Zealand and in emerging markets, such as in the PRC, also have requirements for


approval of drugs for commercial sale with which we must comply prior to marketing in those areas. Regulatory requirements can vary widely from country to country and could delay or prevent the introduction of our drug candidates. Clinical trials conducted in one country may not be accepted by regulatory authorities in other countries, and obtaining regulatory approval in one country does not mean that regulatory approval will be obtained in any other country. Approval processes vary among countries and can involve additional product testing and validation and additional administrative review periods. Seeking non-U.S. regulatory approval could require additional nonclinical studies or clinical trials, which could be costly and time consuming. The non-U.S. regulatory approval process may include all of the risks associated with obtaining FDA approval. For all of these reasons, we may not obtain non-U.S. regulatory approvals on a timely basis, if at all.

        Specifically, in China, the CFDA categorizes domestically-manufactured innovative drug applications as Category 1 and imported innovative drug applications as Category 5. To date, most of local companies' domestically-manufactured drug applications are filed in Category 1 if the drug has not already been approved by the FDA or EMA. Most multinational pharmaceutical companies' drug registration applications are filed in Category 5 applicable to imported drugs, formerly known as Category 3 prior to the reclassification implemented by the CFDA in 2016. These two categories have distinct approval pathways, as described in "Item 1—Business—Regulatory Framework and Structural Advantages of Being a China-Based Research and Development Organization." We believe the local drug registration pathway, Category 1, is a faster and more efficient path to approval in the Chinese market than Category 5. Companies are required to obtain Clinical Trial Application approval before conducting clinical trials in China. This registration pathway has a fast track review and approval mechanism if the drug candidate is on a national priority list. The imported drug registration pathway, Category 5, is more complex and is evolving. China Category 5 registration applications may only be submitted after a drug has obtained an NDA approval and received the CPP granted by a major drug regulatory authority, such as the FDA or EMA.

        Further, in August 2015, the Chinese State Council issued a statement,Opinions on reforming the review and approval process for pharmaceutical products and medical devices that contained several potential policy changes that could benefit the pharmaceutical industry:

        In November 2015, the CFDA released theCircular Concerning Several Policies on Drug Registration Review and Approval, which further clarified the following policies potentially simplifying and accelerating the approval process of clinical trials:


        In February 2016, the CFDA released theOpinions on Priority Review and Approval for Resolving Drug Registration Applications Backlog, which further clarified the following policies potentially accelerating the approval process of certain clinical trials or drug registrations:


A Category 1 designation by the CFDA may be revoked or may not be granted for any of our drug candidates or may not lead to faster development or regulatory review or approval process and does not increase the likelihood that our drug candidates will receive regulatory approval.

        We believe the local drug registration pathway, Category 1, is a faster and more efficient path to approval in the Chinese market than the drug registration pathway for imported drugs under Category 5. Companies are required to obtain Clinical Trial Application approval before conducting clinical trials in China. This registration pathway has a fast track review and approval mechanism if the drug candidate is on a national priority list. Imported drug candidates under Category 5 cannot qualify for the national priority list to benefit from fast track reviews. Our drug candidates are all new therapeutic agents and we have built both research and development, clinical trial capacities, and commercial manufacturing facilities in China. As a result, we expect all of our current drug candidates to fall within the Category 1 application process, but cannot be sure we will be granted or be able to maintain Category 1 designation.

Even if any of our drug candidates receives regulatory approval, they may fail to achieve the degree of market acceptance by physicians, patients, third-party payors, and others in the medical community necessary for commercial success.

        If

Our drugs and any of ourfuture approved drug candidates receives regulatory approval, it may nonetheless fail to gain sufficient market acceptance by physicians, patients, third-party payors and others in the medical community. For example, current cancer treatments like chemotherapy and radiation therapy are well established in the medical community, and doctors may continue to rely on these treatments to the exclusion of our drugs and drug candidates, such as BGB-A317, BGB-3111, BGB-290 and BGB-283.candidates. In addition, physicians, patients and third-party payors may prefer other novel or generic products to ours. If our drugs and drug candidates do not achieve an adequate level of acceptance, the sales of our drugs may be limited and we may not generate significant product sales revenues and we may not become profitable. The degree of market acceptance of our drugs and drug candidates, if approved for commercial sale, will depend on a number of factors, including:

the clinical indications for which our drugs and drug candidates are approved;

physicians, hospitals, cancer treatment centers, and patients considering our drugs and drug candidates as a safe and effective treatment;

treatments;
government agencies, professional societies, practice management groups, insurance carriers, physicians’ groups, private health and science foundations, and organizations publishing guidelines and recommendations recommending our drugs and reimbursement;
the potential and perceived advantages of our drugs and drug candidates over alternative treatments;

the prevalence and severity of any side effects;

product labeling or product insert requirements of the FDA, CFDA, EMA or other comparable regulatory authorities;

limitations or warnings contained in the labeling approved by the FDA, CFDA, EMA or other comparable regulatory authorities;

the timing of market introduction of our drugs and drug candidates as well as competitive drugs;

the cost of treatment in relation to alternative treatments;

If our drug candidates are approved butany drugs that we commercialize fail to achieve market acceptance among physicians, patients, hospitals, third-party payors, cancer treatment centers or others in the medical community, we will not be able to generate significant revenue. Even if our drugs achieve market acceptance, we may not be able to maintain that market acceptance over time if new products or technologies are introduced that are more favorably received than our drugs, are more cost effective or render our drugs obsolete.


We currently have no marketing and sales organization and have nolimited experience in launching and marketing our internally developed drugs and third-party drugs. If we are unable to establishfurther develop marketing and sales capabilities or enter into agreements with third parties to market and sell our drug candidates,drugs and third-party drugs, we may not be able to generate substantial product sales revenue.

In 2017, in connection with our strategic collaboration with Celgene Logistics Sàrl, a Bristol-Myers Squibb company ("BMS"), we were granted an exclusive license in the People's Republic of China ("PRC" or "China"), excluding Hong Kong, Macau and Taiwan, to commercialize BMS’s approved cancer therapies, ABRAXANE®, REVLIMID®, and VIDAZA®, and acquired BMS’s commercial operations in China, excluding certain functions. We currently have no sales,started marketing BMS’s approved drugs in September 2017.
In October 2019, we entered into a strategic collaboration with Amgen with respect to its commercial-stage oncology products XGEVA® (which received approval from the National Medical Products Administration ("NMPA") and was made available in China in September 2019), KYPROLIS® and BLINCYTO® and 20 clinical- and late-preclinical-stage oncology pipeline products, and the agreement became effective on January 2, 2020. In connection with this strategic collaboration, we are authorized to commercialize the oncology products of Amgen in China for five or commercial product distribution capabilitiesseven years and have no experiencethe option to retain one of the three oncology products to commercialize for as long as the product is sold in marketing drugs.China. For each pipeline product that is approved in China, we will also have the right to commercialize the pipeline product for seven years in China and the right to retain approximately one of every three approved pipeline assets, up to a total of six, other than AMG 510, for commercialization in China.
In November 2019, our BTK inhibitor BRUKINSA™ (zanubrutinib) received accelerated approval from the FDA as a treatment for mantle cell lymphoma ("MCL") in adult patients who have received at least one prior therapy and we launched BRUKINSA in the United States soon after approval. In December 2019, our anti-PD-1 antibody tislelizumab received approval from the NMPA as a treatment for patients with classical Hodgkin's Lymphoma ("cHL") who have received at least two prior therapies. We intendexpect to launch tislelizumab in China in the first quarter of 2020.
We continue to build our salesforce in China and the United States to commercialize our internally developed drugs (including BRUKINSA and tislelizumab) and third-party drugs, and any additional drugs or drug candidates that we may develop an in-house marketing organization and sales force,or in-license, which will require significant capital expenditures, management resources and time.
We have limited experience in commercializing our internally developed drugs, such as BRUKINSA and tislelizumab, and third-party drugs, such as ABRAXANE, REVLIMID, and VIDAZA, which we license from BMS, and XGEVA, KYPROLIS and BLINCYTO, which we have the right to commercialize under our strategic collaboration with Amgen. For example, we have limited experience in building and managing a commercial team, conducting a comprehensive market analysis, obtaining state licenses and reimbursement, or managing distributors and a sales force for our drugs. We will be competing with many companies that currently have extensive and well-funded sales and marketing operations. As a result, our ability to successfully commercialize our drug may involve more inherent risk, take longer, and cost more than it would if we were a company with substantial experience launching drugs.
We will have to compete with other pharmaceutical and biotechnology companies to recruit, hire, train and retain marketing and sales personnel.

If we are unable to, or decide not to, establishfurther develop internal sales, marketing, and commercial distribution capabilities for any or all of our drugs, we develop, we will likely pursue collaborative arrangements regarding the sales and marketing of our drugs. However, there can be no assurance that we will be able to establish or maintain such collaborative arrangements, or if we are able to do so, that they will have effective sales forces. Any revenue we receive will depend upon the efforts of such third parties, which may not be successful.parties. We maywould have little or no control over the marketing and sales efforts of such third parties, and our revenue from product sales may be lower than if we had commercialized our drug candidatesdrugs ourselves. We also face competition in our search for third parties to assist us with the sales and marketing efforts offor our drug candidates.

drugs.

There can be no assurance that we will be able to further develop in-houseand successfully maintain internal sales and commercial distribution capabilities or establish or maintain relationships with third-party collaborators to successfully commercialize any product,drug, and as a result, we may not be able to generate substantial product sales revenue.


We face substantial competition, which may result in others discovering, developing, or commercializing competing drugs before or more successfully than we do.

The development and commercialization of new drugs is highly competitive. We face competition with respect to our current drug candidates, and will face competition with respect to any drug candidates that we may seek to develop or commercialize in the future, from major pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies worldwide. There are a number of large pharmaceutical and biotechnology companies that currently market and sell drugs or are pursuing the development of drugs for the treatment of cancer for which we are commercializing our drugs or developing our drug candidates. Some of these competitive drugsFor example, both BRUKINSA and therapies are based on scientific approaches that are the same as or similar to our approach, and others are based on entirely different approaches.tislelizumab face substantial competition. Potential competitors also include academic institutions,

government agencies and other public and private research organizations that conduct research, seek patent protection and establish collaborative arrangements for research, development, manufacturing and commercialization.

        Specifically, there are a large number of companies developing or marketing treatments for cancer, including many major pharmaceutical and biotechnology companies. See "Item 1—Business—Competition."

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize drugs that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than any drugs that we commercialize or may develop. Our competitors also may obtain approval from the FDA, CFDA, EMAU.S. Food and Drug Administration ("FDA"), NMPA, European Medicines Agency ("EMA") or other comparable regulatory authorities for their drugs more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position before we are able to enter the market and or slow our regulatory approval. Furthermore, the regulatory framework in China regarding imported drugs may undergo changes that could erode our competitive advantage with respect to the Chinese domestic regulatory pathway. For example, on March 17, 2017, the CFDA published a draft Decision on Regulation Adjustment on Imported Drugs Registration that if adopted would potentially accelerate the regulatory approval process for imported drugs.

Many of the companies against which we are competing or against which we may compete in the future have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved drugs than we do. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller and other early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These third parties compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs.

Our drug candidates for which we intend to seek approval as biological or drug products may face competition sooner than expected.

        With the enactment of the Biologics Price Competition and Innovation Act of 2009, or BPCIA, as part of the ACA, as amended by the Health Care and Education Reconciliation Act of 2010, or, collectively the ACA, an abbreviated pathway for the approval of biosimilar and interchangeable biological products was created in the United States. The abbreviated regulatory pathway establishes legal authority for the FDA to review and approve biosimilars, including the possible designation of a biosimilar as "interchangeable," based on their similarity to existing reference product. Under the BPCIA, an application for a biosimilar product cannot be approved by the FDA until 12 years after the reference product was approved under a BLA. The BPCIA is complex and is only beginning to be


interpreted and implemented by the FDA. As a result, its ultimate impact, implementation and meaning are subject to uncertainty, and it could have a material adverse effect on the future commercial prospects for our biological products, including BGB-A317, if approved.

        We believe that any of our drugs approved as a biological product under a BLA should qualify for the 12-year period of exclusivity. However:

        Moreover, the extent to which a biosimilar, once approved, will be substituted for any one of our reference products in a way that is similar to traditional generic substitution for non-biological products is not yet clear and will depend on a number of marketplace and regulatory factors that are still developing.

        In addition, a drug product approved under an NDA, such as BGB-3111, BGB-290 or BGB-283, if they were to be approved, could face generic competition earlier than expected. The enactment of the Generic Drug User Fee Amendments of 2012 as part of the Food and Drug Administration Safety and Innovation Act of 2012 established a user fee program that will generate hundreds of millions of dollars in funding for the FDA's generic drug review program. Funding from the user fee program, along with performance goals that the FDA negotiated with the generic drug industry, could significantly decrease the timeframe for FDA review and approval of generic drug applications.

The market opportunities for our drugs and drug candidates may be limited to those patients who are ineligible for or have failed prior treatments and may be small.

        Cancer therapies are sometimes characterized as first line, second line or third line, and the FDA often approves new therapies initially only for third line use. When cancer is detected early enough, first line therapy is sometimes adequate to cure the cancer or prolong life without a cure. Whenever first line therapy, usually chemotherapy, hormone therapy, surgery or a combination of these, proves unsuccessful, second line therapy may be administered. Second line therapies often consist of more chemotherapy, radiation, antibody drugs, tumor targeted small molecules or a combination of these. Third line therapies can include bone marrow transplantation, antibody and small molecule targeted therapies, more invasive forms of surgery and new technologies.

In markets with approved therapies, we have and expect to initially seek approval of our drug candidates as a later stage therapy for patients who have failed other approved treatments. Subsequently, for those drugs that prove to be sufficiently beneficial, if any, we would expect to seek approval as a second line therapy and potentially as a first linefirst-line therapy, but there is no guarantee that our drugs and drug candidates, even if approved, would be approved for second linesecond-line or first linefirst-line therapy. In addition, we may have to conduct additional clinical trials prior to gaining approval for second line or first line therapy.

Our projections of both the number of people who have the cancers we are targeting, as well as the subset of people with these cancers in a position to receive later stage therapy and who have the potential to benefit from treatment with our drugs and drug candidates, are based on our beliefs and estimates. These estimates have been derived from a variety of sources, including scientific literature, surveys of clinics, patient foundations or market research and may prove to be incorrect.inaccurate or based on imprecise data. Further, new studies may change the estimated incidence or prevalence of these cancers. The number of patients may turn out to be lower than expected. Additionally, the potentially addressable patient population for our drugs and drug candidates may be limited or may not be amenable to treatment with our drugs and drug candidates. Even if we


obtain significant market share for our drugs and drug candidates, because the potential target populations are small, we may never achieve profitability without obtaining regulatory approval for additional indications, including use as a firstfirst- or second linesecond-line therapy.

        Our market opportunities may also be limited by competitor treatments that may enter the market. See "—We face substantial competition, which may result in others discovering, developing or commercializing competing drugs before or more successfully than we do."

Even if

If we are not able to continue to obtain, or experience delays in obtaining, required regulatory approvals, we will not be able to commercialize our drugs and drug candidates, and our ability to generate revenue will be materially impaired.
Before obtaining regulatory approvals for the commercial sale of any drug candidate for a target indication, we must demonstrate in preclinical studies and well-controlled clinical trials, and, with respect to approval in the United States, to the satisfaction of the FDA, that the drug candidate is safe and effective, or the biologic drug candidate is safe, pure, and potent, for use for that target indication and that the manufacturing facilities, processes and controls are adequate. In addition to preclinical and clinical data, the new drug application ("NDA") or biologics license application ("BLA") must include significant information regarding the chemistry, manufacturing and controls ("CMC") for the drug candidate. Obtaining approval of an NDA or BLA is a lengthy, expensive and uncertain process, and approval may not be obtained. If we submit an NDA or BLA to the FDA, the FDA decides whether to accept or reject the submission for filing. We cannot be certain that a submission will be accepted for filing and review by the FDA.
We have limited experience in obtaining regulatory approval for our drug candidates. For example, we have limited experience in preparing the required materials for regulatory submission and navigating the regulatory approval process. As a result, our ability to successfully submit an NDA or BLA and obtain regulatory approval for our drug candidates may involve more inherent risk, take longer, and cost more than it would if we were a company with substantial experience in obtaining regulatory approvals.
Regulatory authorities outside of the United States, such as the NMPA and EMA, also have requirements for approval of drugs may become subjectfor commercial sale with which we must comply prior to unfavorable pricing regulations, third party reimbursement practices or healthcare reform initiatives, which could harm our business.

        The regulations that govern regulatory approvals, pricing and reimbursement for new therapeutic productsmarketing in those areas. Regulatory requirements can vary widely from country to country and could delay or prevent the introduction of our drug candidates. Clinical trials conducted in one country may not be accepted by regulatory authorities in other countries, and obtaining regulatory approval in one country does not mean that regulatory approval will be obtained in any other country. SomeApproval processes vary among countries and can involve additional product testing and validation and additional administrative review periods. Seeking non-U.S. regulatory


approval could require additional nonclinical studies or clinical trials, which could be costly and time consuming. The non-U.S. regulatory approval process may include all of the sale pricerisks associated with obtaining FDA approval. For all of these reasons, we may not obtain non-U.S. regulatory approvals on a drug before it can be marketed. In many countries, the pricing review period begins after marketing or licensing approval is granted. In some non-U.S. markets, prescription pharmaceutical pricing remains subjecttimely basis, if at all.
The process to continuing governmental control even after initial approval is granted. As a result, we mightdevelop, obtain regulatory approval for aand commercialize drug candidates is long, complex and costly both inside and outside the United States, China and Europe, and approval is never guaranteed. Even if our drug candidates were to successfully obtain approval from the regulatory authorities, any approval might significantly limit the approved indications for use, or require that precautions, contraindications or warnings be included on the product labeling, or require expensive and time-consuming post-approval clinical trials or surveillance as conditions of approval. Following any approval for commercial sale of our drug candidates, certain changes to the drug, such as changes in a particular country, but thenmanufacturing processes and additional labeling claims, may be subject to price regulations that delayadditional review and approval by the FDA, NMPA and EMA and comparable regulatory authorities. Also, regulatory approval for any of our commercial launch of the drug and negatively impact the revenuescandidates may be withdrawn. If we are ableunable to generate from the sale of theobtain regulatory approval for our drug in that country. Adverse pricing limitations may hinder our ability to recoup our investmentcandidates in one or more drug candidates, even ifjurisdictions, or any approval contains significant limitations, our target market will be reduced and our ability to realize the full market potential of our drug candidates obtain regulatory approval. For example, according to a statement,Opinions on reforming the review and approval process for pharmaceutical products and medical devices, issued by the Chinese State Council in August 2015, the enterprises applying for new drug approval will be required to undertake that the selling price of new drug on PRC mainland market shall not be higher than the comparable market prices of the product in its country of origin or PRC's neighboring markets, as applicable.

        Our ability to commercialize any drugs successfully also will depend in part on the extent to which reimbursement for these drugs and related treatments will be available from government health administration authorities, private health insurers and other organizations. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which medications they will pay for and establish reimbursement levels. A primary trend in the global healthcare industry is cost containment. Government authorities and these third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. Increasingly, third-party payors are requiring that companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. We cannot be sure that reimbursement will be available for any drug that we commercialize and, if reimbursement is available, what the level of reimbursement will be. Reimbursement may impact the demand for, or the price of, any drug for which we obtain regulatory approval. Obtaining reimbursement for our drugs may be particularly difficult because of the higher prices often associated with drugs administered under the supervision of a physician. If reimbursement is not available or is available only to limited levels,harmed. Furthermore, we may not be able to successfully commercializeobtain sufficient funding or generate sufficient revenue and cash flows to continue the development of any other drug candidate that we successfully develop.

        There may be significant delays in obtaining reimbursement for approved productthe future.

We have limited manufacturing capability and must rely on third-party manufacturers to manufacture our commercial products and clinical supplies, and if they fail to meet their obligations, the development and commercialization of our drugs and coverage maydrug candidates could be moreadversely affected.
We have limited than the purposesmanufacturing capabilities and experience. Our drugs and drug candidates are composed of multiple components and require specialized formulations for which the drug is approved by the FDA or other comparable regulatory authorities outside the United States. Moreover, eligibility for reimbursement does not imply that any drug willscale-up and manufacturing could be paid fordifficult. We have limited experience in all cases or atsuch scale-up and manufacturing, requiring us to depend on a rate that covers our costs, including research, development, manufacture, sale and distribution. Interim payments for new drugs, if applicable, may also not be sufficient to cover our costs andlimited number of third parties, who may not be made permanent. Payment rates may vary accordingable to deliver in a timely manner, or at all. In order to develop drugs and drug candidates, apply for regulatory approvals, and commercialize our drugs and drug candidates, we will need to develop, contract for, or otherwise arrange for the usenecessary manufacturing capabilities. There are risks inherent in pharmaceutical manufacturing that could affect the ability of the drug and the clinical setting in which it is used, may be basedour contract manufacturers to meet our delivery time requirements or provide adequate amounts of material to meet our needs.
We currently rely on payments allowed for lower cost drugs that are already reimbursed, and may be incorporated into existing payments for other services. Net prices for drugs may be reduced by mandatory discounts


or rebates required by government healthcare programs or private payors and by any future weakening of laws that presently restrict importsthird-party manufacturers to produce commercial quantities of drugs from countries where they may be sold at lower prices than in the United States. Third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own reimbursement policies. Our inability to promptly obtain coverage and profitable payment rates from both government-funded and private payors for new drugs that we develop could have a material adverse effect on our operating results, our ability to raise capital needed to commercializeare marketing, including in-licensed drugs and our overall financial condition.

Coverageinternally developed drugs, BRUKINSA and reimbursement may be limited or unavailable in certain market segments fortislelizumab. In addition, if any of our other drug candidates which could make it difficultor in-licensed drugs or drug candidates becomes approved for commercial sale, we will need to expand our internal capacity or establish additional third-party manufacturing capacity. Manufacturing partner requirements may require us to sellfund capital improvements, perhaps on behalf of third parties, to support the scale-up of manufacturing and related activities. We may not be able to establish scaled manufacturing capacity for an approved drug in a timely or economic manner, if at all. If we or our third-party manufacturers are unable to provide commercial quantities of such an approved drug, candidates profitably.

        Successful sales of ourwe will have to successfully transfer manufacturing technology to a different manufacturer. Engaging a new manufacturer for such an approved drug candidates, if approved, depend on the availability of adequate coverage and reimbursement from third-party payors. In addition, because our drug candidates represent new approaches to the treatment of cancer, we cannot accurately estimate the potential revenue from our drug candidates.

        Patients who are provided medical treatment for their conditions generally rely on third-party payors to reimburse all or part of the costs associated with their treatment. Adequate coverage and reimbursement from governmental healthcare programs, such as Medicare and Medicaid in the United States, and commercial payors are critical to new drug acceptance.

        Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which drugs and treatments they will cover and the amount of reimbursement. Coverage and reimbursement by a third-party payor may depend upon a number of factors, including the third-party payor's determination that use of a drug is:

        In the United States, no uniform policy of coverage and reimbursement for drugs exists among third-party payors. As a result, obtaining coverage and reimbursement approval of a drug from a government or other third-party payor is a time-consuming and costly process that could require us to provideconduct comparative studies or utilize other means to each payor supporting scientific, clinicaldetermine bioequivalence of the new and cost-effectiveness data forprior manufacturers’ products, which could delay or prevent our ability to commercialize such an approved drug. If we or any of these manufacturers is unable or unwilling to increase its manufacturing capacity or if we are unable to establish alternative arrangements on a timely basis or on acceptable terms, the usedevelopment and commercialization of such an approved drug may be delayed or there may be a shortage in supply. Any inability to manufacture our drugs, drug candidates, in-licensed drugs and drug candidates or future approved drugs in sufficient quantities when needed could seriously harm our business and our financial results.

Manufacturers of our approved drugs, onif any, must comply with good manufacturing practice ("GMP") requirements enforced by the FDA, NMPA, EMA and other comparable foreign health authorities through facilities inspection programs. These requirements include quality control, quality assurance, and the maintenance of records and documentation. Manufacturers of our approved drugs may be unable to comply with these GMP requirements and with other FDA, NMPA, EMA, state, and foreign regulatory requirements. A failure to comply with these requirements may result in fines and civil penalties, suspension of production, suspension or delay in product approval, product seizure or recall, or withdrawal of product approval. If the safety of any quantities supplied is compromised due to a payor-by-payor basis, with no assurance that coverage and adequate reimbursement will be obtained. Even ifmanufacturer’s failure to adhere to applicable laws or for other reasons, we obtain coverage for a given drug, the resulting reimbursement payment rates mightmay not be adequate for us to achieve or sustain profitability or may require co-payments that patients find unacceptably high. Additionally, third-party payors may not cover, or provide adequate reimbursement for, long-term follow-up evaluations required following the use of our genetically modified drugs. Patients are unlikely to use our drug candidates unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of our drug candidates. Because our drug candidates have a higher cost of goods than conventional therapies, and may require long-term follow up evaluations, the risk that coverage and reimbursement rates may be inadequate for us to achieve profitability may be greater.

        The Chinese State Council asked central and provincial authorities across the PRC to promote a medical insurance program for major illnesses. By the end of 2015, all urban and rural residents covered by basic medical insurance programs should be covered by the insurance program for major illnesses, according to Chinese State Council policy number 2015-57, issued on July 28, 2015. As a complement to basic insurance programs, this program is required to cover at least 50% of the medical


cost as incurred by treating major illnesses, but falls out of the coverage of the basic insurance programs. The Chinese State Council requires provincial authorities to increase reimbursement rates over the next three years.

        According to the PRC Central Government's guidance issued in March 2015, each province will decide which drugs to include in its provincial major illness reimbursement lists and the percentage of reimbursement, based on local funding. For example, Zhejiang province, located in the Yangtze river delta area with a population of 55 million, announced its provincial major illness drug reimbursement list in early 2015. The list includes 31 expensive drugs, among which 15 are targeted therapy agents for cancer, including Glivec, Ireesa, Erbitux, Herceptin, and Rituxan. Although it will take three years to establish a comprehensive national coverage, the affordability of the expensive, novel cancer agents to Chinese patients will improve significantly and the targeted therapy market is expected to enter a fast growing period.

        We intend to seek approval to market our drug candidates in the United States, China, Europe and in other selected jurisdictions. If we obtain approval in one or more non-U.S. jurisdictions for our drug candidates, we will be subject to rules and regulations in those jurisdictions. In some non-U.S. countries, particularly those in the European Union, the pricing of drugs and biologics is subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time after obtaining regulatory approval of a drug candidate. In addition, market acceptance and sales of our drug candidates will depend significantly on the availability of adequate coverage and reimbursement from third-party payors for our drug candidates and may be affected by existing and future health care reform measures.

Recently enacted and future legislation may increase the difficulty and cost for usable to obtain regulatory approval of andfor or successfully commercialize our drug candidates and affect the prices we may obtain.

        In the United States, PRC, European Union and some other jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay regulatory approval ofdrugs, which would seriously harm our drug candidates, restrict or regulate post-approval activities and affect our ability to profitably sell any drug candidates for which we obtain regulatory approval.

        In the United States, the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, or the MMA, changed the way Medicare covers and pays for pharmaceutical products. The legislation expanded Medicare coverage for drug purchases by the elderly and introduced a new reimbursement methodology based on average sales prices for physician-administered drugs. In addition, this legislation provided authority for limiting the number of drugs that will be covered in any therapeutic class. Cost reduction initiatives and other provisions of this legislation could decrease the coverage and price that we receive for any approved products. While the MMA only applies to drug benefits for Medicare beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own reimbursement rates. Therefore, any reduction in reimbursement that results from the MMA may result in a similar reduction in payments from private payors.

        More recently, in March 2010, then President Obama signed into law the ACA, a sweeping law intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add new transparency requirements for the healthcare and health insurance industries, impose new taxes and fees on the health industry and impose additional health policy reforms.

business.

        Among the provisions of the ACA of importance to our potential drug candidates are the following:

        In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted. These changes included aggregate reductions to Medicare payments to providers of up to 2% per fiscal year, starting in 2013. In January 2013, then President Obama signed into law the American Taxpayer Relief Act of 2012, which, among other things, reduced Medicare payments to several providers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. These laws may result in additional reductions in Medicare and other healthcare funding.

        We expect that the ACA, as well as other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and in additional downward pressure on the price that we receive for any approved drug. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our drugs.

        Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities for pharmaceutical products. We cannot be sure whether additional legislative changes will be enacted, or whether FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the regulatory approvals of our drug candidates, if any, may be. In addition, increased scrutiny by the U.S. Congress of the FDA's approval process may significantly delay or prevent regulatory approval, as well as subject us to more stringent product labeling and post-marketing testing and other requirements.

        As a result of the 2016 election in the United States, the fate of the ACA and other healthcare laws is uncertain. The United States House of Representatives is considering approval of legislation to repeal parts of the ACA, but it is uncertain whether Congress will replace the law and what any replacement law would provide.


We may be subject, directly or indirectly, to applicable U.S. federal and state anti-kickback, false claims laws, physician payment transparency laws, fraud and abuse laws or similar healthcare and security laws and regulations in the United States and other jurisdictions, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future earnings.

Healthcare providers, physicians and others play a primary role in the recommendation and prescription of any products for which we obtain regulatory approval. If we obtain FDA approval for any of our drug candidates and begin commercializing those drugs in the United States, ourOur operations may beare subject to various federal and state fraud and abuse laws, including, without limitation, the federal Anti-Kickback Statute, the federal False Claims Act, and physician payment sunshine laws and regulations. These laws may impact, among other things, our proposed sales, marketing and education programs. In addition, we may beare subject to patient privacy regulation by both the federal government and the states in which we conduct our business. The laws that may affect our ability to operate include:


Additionally, we are subject to state and non-U.S. equivalents of each of the healthcare laws described above, among others, some of which may be broader in scope and may apply regardless of the payor. Many U.S. states have adopted laws similar to the federal Anti-Kickback Statute, some of which apply to the referral of patients for healthcare services reimbursed by any source,third-party payor, not just governmental payors, includingbut also private insurers. In addition, someThese laws are enforced by various state agencies and through private actions. Some states have passed laws that require pharmaceutical companies to comply with the April 2003 Office of Inspector General Compliance Program Guidance for Pharmaceutical Manufacturers and/or other voluntary industry codes of conduct that restrict the Pharmaceutical Researchpayments made to healthcare providers and Manufacturers of America's Code on Interactions with Healthcare Professionals.other potential referral sources. Several states and local laws also impose other marketing restrictions or require pharmaceutical companies to make marketing or price disclosures to the state.state, require drug manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers, and require the registration of pharmaceutical sales representatives. State laws also govern the privacy and security of health information in some circumstances. These data privacy and security laws may differ from each other in significant ways and often are not pre-empted by HIPAA, which may complicate compliance efforts. There are ambiguities as to what is required to comply with these state requirements, and if we fail to comply with an applicable state law requirement, we could be subject to penalties.

        Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of our business activities could be subject to challenge under one or more of such laws. In addition, recent health care reform legislation has strengthened these laws. For example, the ACA, among other things, amends the intent requirement of the federal Anti-Kickback and criminal healthcare fraud statutes. As a result of such amendment, a person or entity no longer needs to have actual knowledge of these statutes or specific intent to violate them in order to have committed a violation. Moreover, the ACA provides that the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act.

Violations of fraud and abuse laws may be punishable by criminal and/or civil sanctions, including penalties, fines and/or exclusion or suspension from federal and state healthcare programs such as Medicare and Medicaid and debarment from contracting with the U.S. government. In addition, private individuals have the ability to bring actions on behalf of the U.S. government under the federal False Claims Act as well as under the false claims laws of several states.

Neither the U.S. government nor the U.S. courts have provided definitive guidance on the applicationapplicability of fraud and abuse laws to our business. Law enforcement authorities are increasingly focused on enforcing these laws, and it is possible that some of our practices may be challenged under these laws. Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of civil, criminal and administrative penalties, damages, disgorgement, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, individual imprisonment, reputational harm, diminished profits and future earnings, and curtailment or restructuring of our operations, anyas well as additional reporting obligations and oversight if we become subject to a corporate integrity agreement or other agreement to resolve allegations of which could adversely affect our ability to operate our business and our results of operations. non-compliance with these laws.
In addition, the approval, commercialization, and commercialization ofother activities related to any of our drugs and drug candidates outside the United States will also likely subject us to non-U.S. equivalents of the healthcare laws such as those mentioned above, among other non-U.S. laws.

As with the state equivalents mentioned above, some of these non-U.S. laws may be broader in scope. Data privacy and security laws and regulations in non-U.S. jurisdictions may also be more stringent than those in the United States (such as the European Union ("EU"), which adopted the General Data Protection Regulation, which became effective in May 2018).

If any of the physicians or other providers or entities with whom we expect to do business with are found to be not in compliance with applicable laws, they may be subject to criminal, civil or


administrative sanctions, including exclusions from government funded healthcare programs, which may also adversely affect our business.

We may explore the licensing of development and/or commercialization rights or other forms of collaboration worldwide, which will expose us to additional risks of conducting business in additional international markets.

Non-U.S. markets are an important component of our growth strategy. For example, in connection with our collaboration with Amgen we have been granted the right to commercialize three of Amgen’s oncology products in China for five or seven years and will have the option to retain one of the three oncology products to commercialize for as long as the product is sold in

China. We have also agreed to collaborate with Amgen on the global development and commercialization in China of 20 Amgen oncology pipeline products. We initially intend to focus on opportunities in China, in particular. If we fail to obtain licenses or enter into collaborationcollaborative arrangements with third parties in theseother markets, or if these parties are not successful, our revenue-generating growth potential will be adversely affected. Moreover, international business relationships subject us to additional risks that may materially adversely affect our ability to attain or sustain profitable operations, including:

efforts to enter into collaboration or licensing arrangements with third parties in connection with our international sales, marketing and distribution efforts may increase our expenses or divert our management'smanagement’s attention from the acquisition or development of drug candidates;

changes in a specific country's or region's political and cultural climate or economic condition;

differing regulatory requirements for drug approvals and marketing internationally;

difficulty of effective enforcement of contractual provisions in local jurisdictions;

potential third-party patent rights or potentially reduced protection for intellectual property rights;

potential third-party patent rights;

unexpected changes in tariffs, trade barriers and regulatory requirements;

requirements, including the loss of normal trade status between China and the United States;
economic weakness, including inflation or political instability, particularly in non-U.S. economies and markets;

inflation;
compliance with tax, employment, immigration and labor laws for employees traveling abroad;

the effects of applicable non-U.S. tax structures and potentially adverse tax consequences;

currency fluctuations, which could result in increased operating expenses and reduced revenue, and other obligations incidental to doing business in another country;

revenue;
workforce uncertainty and labor unrest, particularly in non-U.S. countries where labor unrest is more common than in the United States;

the potential for so-called parallel importing, which is what happens when a local seller, faced with high or higher local prices, opts to import goods from a non-U.S. market with low or lower prices rather than buying them locally;

unrest;
failure of our employees and contracted third parties to comply with Office of Foreign Asset Control rules and regulations and the Foreign Corrupt Practices Act;

production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad;Act and

other anti-bribery and corruption laws; and
business interruptions resulting from geo-political actions, including trade disputes, war and terrorism, disease or public health epidemics, such as the coronavirus impacting China and elsewhere, or natural disasters, including earthquakes, volcanoes, typhoons, floods, hurricanes and fires.

These and other risks may materially adversely affect our ability to attain or sustain revenue from international markets.

The illegal distribution and sale by third parties of counterfeit versions of our drugs or stolen products could have a negative impact on our reputation and business.
Third parties might illegally distribute and sell counterfeit or unfit versions of our drugs, which do not meet our or our collaborators’ rigorous manufacturing and testing standards. A patient who receives a counterfeit or unfit drug may be at risk for a number of dangerous health consequences. Our reputation and business could suffer harm as a result of counterfeit or unfit drugs sold under our or our collaborators’ brand name(s). In addition, thefts of inventory at warehouses, plants or while in-transit, which are not properly stored and which are sold through unauthorized channels, could adversely impact patient safety, our reputation and our business.
Risks Related to Clinical Development and Regulatory Approval of Our Drugs and Drug Candidates
We depend substantially on the success of the clinical development of our drugs and drug candidates. If we are unable to successfully complete clinical development, obtain additional regulatory approvals and commercialize our drugs and drug candidates, or experience significant delays in doing so, our business will be materially harmed.
Our business depends on the successful development, regulatory approval and commercialization of our drugs and drug candidates for the treatment of patients with cancer, such as BRUKINSA, for which we obtained FDA approval for the treatment for MCL in adult patients who have received at least one prior therapy, and tislelizumab, for which we obtained NMPA approval for the treatment of patients with cHL who have received at least two prior therapies, and other drug candidates we may develop. We have invested a significant portion of our efforts and financial resources in the development of our drugs and drug candidates. The success of our drugs and drug candidates depends on several factors, including:
successful enrollment in, and completion of, clinical trials, as well as completion of preclinical studies;
favorable safety and efficacy data from our clinical trials and other studies;
receipt of regulatory approvals;

establishing commercial manufacturing capabilities, either by building facilities ourselves or making arrangements with third-party manufacturers;
the performance by contract research organizations ("CROs") or other third parties we may retain of their duties to us in a manner that complies with our protocols and applicable laws and that protects the integrity of the resulting data;
obtaining and maintaining patent, trade secret and other intellectual property protection and regulatory exclusivity;
ensuring we do not infringe, misappropriate or otherwise violate the valid patent, trade secret or other intellectual property rights of third parties;
successfully launching our drugs and drug candidates, if and when approved;
obtaining favorable reimbursement from third-party payors for drugs and drug candidates, if and when approved;
competition with other products;
continued acceptable safety profile following regulatory approval; and
manufacturing or obtaining sufficient supplies of our drugs, drug candidates and any competitor drug products that may be necessary for use in clinical trials for evaluation of our drug candidates and commercialization of our drugs.
If we do not achieve and maintain one or more of these factors in a timely manner or at all, we could experience significant delays in our ability or be unable to obtain additional regulatory approvals for and/or to successfully commercialize our drugs and drug candidates, which would materially harm our business and we may not be able to generate sufficient revenues and cash flows to continue our operations.
Clinical drug development involves a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be predictive of future trial results.
Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the clinical trial process. The results of preclinical studies and early clinical trials of our drug candidates may not be predictive of the results of later-stage clinical trials, and initial or interim results of a trial may not be predictive of the final results. Drug candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical trials. In some instances, there can be significant variability in safety and/or efficacy results between different trials of the same drug candidate due to numerous factors, including changes in trial procedures set forth in protocols, differences in the size and type of the patient populations, including genetic differences, patient adherence to the dosing regimen and other trial protocol elements and the rate of dropout among clinical trial participants. In the case of any trials we conduct, results may differ from earlier trials due to the larger number of clinical trial sites and additional countries and languages involved in such trials. A number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in advanced clinical trials due to lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier trials. Our future clinical trial results may not be favorable.
Even if our future clinical trial results show favorable efficacy and impressive durability of anti-tumor responses, not all patients may benefit. For certain drugs, including checkpoint inhibitors, and in certain indications, it is likely that the majority of patients may not respond to the agents at all, some responders may relapse after a period of response and certain tumor types may appear particularly resistant.
If clinical trials of our drug candidates fail to demonstrate safety and efficacy to the satisfaction of regulatory authorities or do not otherwise produce positive results, we may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our drug candidates.
Before obtaining regulatory approval for the sale of our drug candidates, we must conduct extensive clinical trials to demonstrate the safety and efficacy of our drug candidates in humans. We may experience numerous unexpected events during, or as a result of, clinical trials that could delay or prevent our ability to receive regulatory approval or commercialize our drug candidates, including but not limited to: regulators, institutional review boards ("IRBs"), or ethics committees may not authorize us or our investigators to commence a clinical trial or conduct a clinical trial at a prospective trial site; our inability to reach agreements on acceptable terms with prospective CROs and trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites; manufacturing issues, including problems with manufacturing, supply quality, compliance with current GMP, or obtaining sufficient quantities of a drug candidate for use in a clinical trial or for commercialization; clinical trials of our drug candidates may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct additional clinical trials or abandon drug development programs; the

number of patients required for clinical trials of our drug candidates may be larger than we anticipate, enrollment may be insufficient or slower than we anticipate or patients may drop out at a higher rate than we anticipate; our third-party contractors, including clinical investigators, may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all; we might have to suspend or terminate clinical trials of our drug candidates for various reasons, including a finding of a lack of clinical response or other unexpected characteristics or a finding that participants are being exposed to unacceptable health risks; regulators, IRBs or ethics committees may require that we or our investigators suspend or terminate clinical research or not rely on the results of clinical research for various reasons, including noncompliance with regulatory requirements; the cost of clinical trials of our drug candidates may be greater than we anticipate; and the supply or quality of our drugs and drug candidates, companion diagnostics or other materials necessary to conduct clinical trials of our drug candidates or commercialization of our drugs may be insufficient or inadequate.
If we are required to conduct additional clinical trials or other testing of our drug candidates beyond those that we currently contemplate, if we are unable to successfully complete clinical trials of our drug candidates or other testing, if the results of these trials or tests are not positive or are only modestly positive or if they raise safety concerns, we may:
be delayed in obtaining regulatory approval for our drug candidates;
not obtain regulatory approval at all;
obtain approval for indications that are not as broad as intended;
have the drug removed from the market after obtaining regulatory approval;
be subject to additional post-marketing testing requirements;
be subject to warning labels or restrictions on how the drug is distributed or used; or
be unable to obtain reimbursement for use of the drug.
Significant clinical trial, manufacturing or regulatory delays may also increase our development costs and could shorten any periods during which we have the exclusive right to commercialize our drug candidates or allow our competitors to bring drugs to market before we do. This could impair our ability to commercialize our drug candidates and may harm our business and results of operations.
If we encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed or otherwise adversely affected.
The timely completion of clinical trials in accordance with their protocols depends, among other things, on our ability to enroll a sufficient number of patients who remain in the trial until its conclusion. We may experience difficulties in patient enrollment in our clinical trials for a variety of reasons, including the size and nature of the patient population and the patient eligibility criteria defined in the protocol, competition from competing companies, and natural disasters or public health epidemics, such as the coronavirus impacting China and elsewhere.
Our clinical trials will likely compete with other clinical trials for drug candidates that are in the same therapeutic areas as our drug candidates, and this competition will reduce the number and types of patients available to us, because some patients who might have opted to enroll in our trials may instead opt to enroll in a trial being conducted by one of our competitors. Because the number of qualified clinical investigators and clinical trial sites is limited, we expect to conduct some of our clinical trials at the same clinical trial sites that some of our competitors use, which will reduce the number of patients who are available for our clinical trials at such clinical trial sites. Even if we are able to enroll a sufficient number of patients in our clinical trials, delays in patient enrollment may result in increased costs or may affect the timing or outcome of the planned clinical trials, which could delay or prevent completion of these trials and adversely affect our ability to advance the development of our drug candidates.

Risks Related to Extensive Government Regulation
All material aspects of the research, development, manufacturing and commercialization of pharmaceutical products are heavily regulated.
All jurisdictions in which we conduct or intend to conduct our pharmaceutical-industry activities regulate these activities in great depth and detail. We initially intend to focus our activities in the major markets of the United States, China, EU, and other select countries. These geopolitical areas all strictly regulate the pharmaceutical industry, and in doing so they employ broadly similar regulatory strategies, including regulation of product development and approval, manufacturing, and marketing, sales

and distribution of products. However, there are differences in the regulatory regimes-some minor, some significant-that make for a more complex and costly regulatory compliance burden for a company like ours that plans to operate in each of these regions.
The process of obtaining regulatory approvals and compliance with appropriate laws and regulations require the expenditure of substantial time and financial resources. Failure to comply with the applicable requirements at any time during the product development process, approval process, or after approval, may subject an applicant to administrative or judicial sanctions. These sanctions could include a regulator’s refusal to approve pending applications, withdrawal of an approval, license revocation, a clinical hold, voluntary or mandatory product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement or civil or criminal penalties. The failure to comply with these regulations could have a material adverse effect on our business. For example, although we obtained FDA approval of BRUKINSA for the treatment of adult patients with MCL who have received at least one prior therapy and NMPA approval of tislelizumab for patients with cHL who have received at least two prior therapies, the FDA and NMPA could later withdraw these approvals. In order to market approved products in any given jurisdiction, we must comply with numerous and varying regulatory requirements of such jurisdiction regarding safety, efficacy and quality. In any event, the receipt of FDA, NMPA or other regulatory approval does not assure ultimate success of our commercialization efforts for our drugs.
The approval processes of regulatory authorities in the United States, China, Europe and other comparable regulatory authorities are lengthy, time consuming and inherently unpredictable. If we are ultimately unable to obtain regulatory approval for our drug candidates, our business will be substantially harmed.
The time required to obtain approval by the FDA, the NMPA, the EMA, and other comparable regulatory authorities is unpredictable and typically takes many years following the commencement of preclinical studies and clinical trials and depends on numerous factors, including the substantial discretion of the regulatory authorities.
Our drug candidates could be delayed or fail to receive regulatory approval for many reasons, including:
failure to begin or complete clinical trials due to disagreements with regulatory authorities;
failure to demonstrate that a drug candidate is safe and effective or that a biologic candidate is safe, pure, and potent for its proposed indication;
failure of clinical trial results to meet the level of statistical significance required for approval;
reporting or data integrity issues related to our clinical trials;
disagreement with our interpretation of data from preclinical studies or clinical trials;
changes in approval policies or regulations that render our preclinical and clinical data insufficient for approval or require us to amend our clinical trial protocols;
regulatory requests for additional analyses, reports, data, nonclinical studies and clinical trials, or questions regarding interpretations of data and results and the emergence of new information regarding our drug candidates or other products;
failure to satisfy regulatory conditions regarding endpoints, patient population, available therapies and other requirements for our clinical trials in order to support marketing approval on an accelerated basis or at all;
our failure to conduct a clinical trial in accordance with regulatory requirements or our clinical trial protocols; and
clinical sites, investigators or other participants in our clinical trials deviating from a trial protocol, failing to conduct the trial in accordance with regulatory requirements, or dropping out of a trial.
The FDA, NMPA, EMA or a comparable regulatory authority may require more information, including additional preclinical, CMC, and/or clinical data, to support approval, which may delay or prevent approval and our commercialization plans, or we may decide to abandon the development program.
Changes in regulatory requirements and guidance may also occur, and we may need to amend clinical trial protocols submitted to applicable regulatory authorities to reflect these changes. Amendments may require us to resubmit clinical trial protocols to IRBs or ethics committees for re-examination, which may impact the costs, timing or successful completion of a clinical trial.

If we experience delays in the completion of, or the termination of, a clinical trial of any of our drug candidates, the commercial prospects of that drug candidate will be harmed, and our ability to generate product sales revenues from any of those drug candidates will be delayed. In addition, any delays in completing our clinical trials will increase our costs, slow down our drug candidate development and approval process, and jeopardize our ability to commence product sales and generate related revenues for that candidate. Any of these occurrences may harm our business, financial condition and prospects significantly. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our drug candidates.
Our development activities and regulatory filings also could be harmed or delayed by a shutdown of the U.S. government, including the FDA, or other governments and regulatory authorities.
We believe that our drug candidates’ designation in China as Category 1 products should confer certain regulatory advantages to us. These advantages may not result in commercial benefits to us as we expect, and they might be changed in the future in a manner adverse to us.
In China, prior to seeking approval from the NMPA, a pharmaceutical company needs to determine the drug’s registration category, which will determine the requirements for its clinical trial and marketing application. These categories range from Category 1, for drugs incorporating a new chemical entity that has not previously been marketed anywhere in the world, to Category 2, for drugs with new indications, dosage forms or routes of administration and the like, to Categories 3 and 4, for certain generic drugs, to Category 5, for “originator” (what would be known elsewhere as innovative) or generic drugs previously marketed abroad but not yet approved for marketing in China. Therapeutic biologics follow a similar classification system. All of our internally developed drug candidates are classified as Category 1 based on the respective clinical trial approval from the NMPA, which is a favored category for regulatory review and approval.
The NMPA has adopted several mechanisms for expedited review and approval for drug candidates that apply to Category 1 drug candidates. While we believe that the Category 1 designation of our internally developed drug candidates should provide us with a significant regulatory, and therefore commercial, advantage over non-Chinese companies seeking to market products in China, we cannot be sure that this will be the case. The pharmaceutical regulatory environment is evolving quickly, and changes in laws, regulations, enforcement and internal policies could result in the “favored” status of Category 1 products changing or being eliminated altogether or our products classification in Category 1 changing. We cannot be certain that the advantages we believe will be conferred by our Category 1 classifications will be realized or result in any material development or commercial advantage.
The absence of patent-linkage, patent-term extension and regulatory exclusivity for NMPA-approved pharmaceutical products could increase the risk of early generic competition with our products in China.
In the United States, the Federal Food, Drug, and Cosmetic Act, as amended by the law commonly referred to as the “Hatch-Waxman Amendments,” provides the opportunity for patent-term restoration of up to five years to reflect patent term lost during certain portions of product development and the FDA regulatory review process. The Hatch-Waxman Amendments also have a process for patent linkage, pursuant to which FDA will stay approval of certain follow-on applications during the pendency of litigation between the follow-on applicant and the patent holder or licensee, generally for a period of 30 months. Finally, the Hatch-Waxman Amendments provide for statutory exclusivities that can prevent submission or approval of certain follow-on marketing applications. For example, federal law provides a five-year period of exclusivity within the United States to the first applicant to obtain approval of a new chemical entity (as defined) and three years of exclusivity protecting certain innovations to previously approved active ingredients where the applicant was required to conduct new clinical investigations to obtain approval for the modification. Similarly, the Orphan Drug Act provides seven years of market exclusivity for certain drugs to treat rare diseases, where FDA designates the drug candidate as an orphan drug and the drug is approved for the designated orphan indication. These provisions, designed to promote innovation, can prevent competing products from entering the market for a certain period of time after FDA grants marketing approval for the innovative product.
In China, however, there is no currently effective law or regulation providing patent term extension, patent linkage, or data exclusivity (referred to as regulatory data protection). Therefore, a lower-cost generic drug can emerge onto the market much more quickly. Chinese regulators have set forth a framework for integrating patent linkage and data exclusivity into the Chinese regulatory regime, as well as for establishing a pilot program for patent term extension. The Economic and Trade Agreement Between the United States of America and the People's Republic of China announced in January 2020 (the "Trade Agreement") also provides for patent linkage systems and patent term extension systems. To be implemented, this framework will require adoption of legislation and regulations. To date, the NMPA has issued several draft implementing regulations in this regard for public comment but no regulations have been formally issued, and these concepts were not included in the revised Drug Administration Law that became effective on December 1, 2019 and contains significant other changes to the drug regulatory landscape in China. These factors result in weaker protection for us against generic competition in China than could be

available to us in the United States until the relevant implementing regulations for extension, patent linkage, or data exclusivity are put into effect officially in China.
Chinese manufacturing facilities have historically experienced issues operating in line with established GMPs and international best practices, and passing FDA, NMPA and EMA inspections, which may result in a longer and costlier current GMP inspection and approval process by the FDA, NMPA or EMA for our Chinese manufacturing processes and third-party contract manufacturers.
To obtain FDA, NMPA and EMA approval for our drug candidates in the United States, China and Europe, we will need to undergo strict pre-approval inspections of our manufacturing facilities, which we have located in China, or the manufacturing facilities of our contract manufacturers located in China and elsewhere. Historically, some manufacturing facilities in China have had difficulty meeting the FDA’s, NMPA's or EMA's standards. When inspecting our or our contractors' Chinese manufacturing facilities, the FDA, NMPA or EMA might cite GMP deficiencies, both minor and significant, which we may not be required to disclose. Remediating deficiencies can be laborious and costly and consume significant periods of time. Moreover, if the FDA, NMPA or EMA notes deficiencies as a result of its inspection, it will generally reinspect the facility to determine if the deficiency was remediated to its satisfaction. The FDA, NMPA or EMA may note further deficiencies as a result of its reinspection, either related to the previously identified deficiency or otherwise. If we cannot satisfy the FDA, NMPA and EMA as to our compliance with GMP in a timely basis, marketing approval for our drug candidates could be seriously delayed, which in turn would delay commercialization of our drug candidates.
Undesirable adverse events caused by our drugs and drug candidates could interrupt, delay or halt clinical trials, delay or prevent regulatory approval, limit the commercial profile of an approved label, or result in significant negative consequences following any regulatory approval.
Undesirable adverse events ("AEs") caused by our drugs and drug candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA, NMPA, EMA or other comparable regulatory authorities, or could result in limitations or withdrawal following approvals. If the conduct or results of our trials or patient experience following approval reveal a high and unacceptable severity or prevalence of AEs, our trials could be suspended or terminated and the FDA, NMPA, EMA or other comparable regulatory authorities could order us to cease further development of, or deny approval of, our drug candidates or require us to cease commercialization following approval.
Numerous drug-related AEs and serious AEs ("SAEs") have been reported in our clinical trials. Some of these events have led to patient death. Drug-related AEs or SAEs could affect patient recruitment or the ability of enrolled subjects to complete the trial and could result in product liability claims. Any of these occurrences may harm our reputation, business, financial condition and prospects significantly. In our periodic and current reports filed with the SEC and our press releases and scientific and medical presentations released from time to time we disclose clinical results for our drug candidates, including the occurrence of AEs and SAEs. Each such disclosure speaks only as of the date of the data cutoff used in such report, and we undertake no duty to update such information unless required by applicable law. Also, a number of immune-related adverse events ("IRAEs") have been associated with treatment with checkpoint inhibitors such as tislelizumab, including immune-mediated pneumonitis, colitis, hepatitis, endocrinopathies, nephritis and renal dysfunction, skin adverse reactions, and encephalitis. These IRAEs may be more common in certain patient populations (potentially including elderly patients) and may be exacerbated when checkpoint inhibitors are combined with other therapies.
Additionally, undesirable side effects caused by our drugs and drug candidates, or caused by our drugs and drug candidates when used in combination with other drugs, could potentially cause significant negative consequences, including:
regulatory authorities could delay or halt pending clinical trials;
we may suspend, delay or alter development of the drug candidate or marketing of the drug;
regulatory authorities may withdraw approvals or revoke licenses of the drug, or we may determine to do so even if not required;
regulatory authorities may require additional warnings on the label;
we may be required to implement a Risk Evaluation Mitigation Strategy ("REMS") for the drug, as is the case with REVLIMID, or, if a REMS is already in place, to incorporate additional requirements under the REMS, or to develop a similar strategy as required by a regulatory authority;
we may be required to conduct post-market studies; and

we could be sued and held liable for harm caused to subjects or patients.
Any of these events could prevent us from achieving or maintaining market acceptance of the particular drug or drug candidate, and could significantly harm our business, results of operations and prospects.
Our drugs and any future approved drug candidates will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense and we may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with our drugs and drug candidates.
Our drugs and any additional drug candidates that are approved will be subject to ongoing regulatory requirements for manufacturing, labeling, packaging, storage, advertising, promotion, sampling, record-keeping, conduct of post-marketing studies, and submission of safety, efficacy, and other post-market information, including both federal and state requirements in the United States and requirements of comparable regulatory authorities in China and other countries. For example, BRUKINSA and tislelizumab will continue to be subject to post-approval development and regulatory requirements, which may limit how they are manufactured and marketed, and could materially impair our ability to generate revenue. As such, we and our third-party manufacturers will be subject to ongoing review and periodic inspections to assess compliance with applicable post-approval regulations. Additionally, to the extent we want to make certain changes to the approved products, product labeling, or manufacturing processes, we will need to submit new applications or supplements to regulatory authorities for approval.
Manufacturers and manufacturers’ facilities are required to comply with extensive FDA, NMPA, EMA and comparable regulatory authority requirements, including, in the United States, ensuring that quality control and manufacturing procedures conform to GMP regulations. As such, we and our contract manufacturers are and will be subject to continual review and inspections to assess compliance with GMP and adherence to commitments made in any NDA or BLA, other marketing application, and previous responses to any inspection observations. Accordingly, we and others with whom we work must continue to expend time, money and effort in all areas of regulatory compliance, including manufacturing, production and quality control.
The regulatory approvals for our drugs and any approvals that we receive for our drug candidates are and may be subject to limitations on the approved indicated uses for which the drug may be marketed or to the conditions of approval, which could adversely affect the drug’s commercial potential or contain requirements for potentially costly post-marketing testing and surveillance to monitor the safety and efficacy of the drug or drug candidate. The FDA, NMPA, EMA or comparable regulatory authorities may also require a REMS program or comparable program as a condition of approval of our drug candidates or following approval, as is the case with REVLIMID. In addition, if the FDA, NMPA, EMA or a comparable regulatory authority approves our drug candidates, we will have to comply with requirements including, for example, submissions of safety and other post-marketing information and reports, establishment registration, as well as continued compliance with GMP and GCP for any clinical trials that we conduct post-approval.
The FDA, NMPA, EMA or comparable regulatory authorities may seek to impose a consent decree or withdraw marketing approval if compliance with regulatory requirements is not maintained or if problems occur after the drug reaches the market. Later discovery of previously unknown problems with our drugs or drug candidates or with our drug’s manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical studies to assess new safety risks; or imposition of distribution restrictions or other restrictions under a REMS program. Other potential consequences include, among other things:
restrictions on the marketing or manufacturing of our drugs, withdrawal of the product from the market, or voluntary or mandatory product recalls;
fines, untitled or warning letters, or holds on clinical trials;
refusal by the FDA, NMPA, EMA or comparable regulatory authorities to approve pending applications or supplements to approved applications filed by us or suspension or revocation of license approvals or withdrawal of approvals;
product seizure or detention, or refusal to permit the import or export of our drugs and drug candidates; and
injunctions or the imposition of civil or criminal penalties.
The FDA, NMPA, EMA and other regulatory authorities strictly regulate the marketing, labeling, advertising and promotion of products that are placed on the market. Drugs may be promoted only for their approved indications and for use in accordance with the provisions of the approved label. The FDA, NMPA, EMA and other regulatory authorities actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted

off-label uses may be subject to significant liability. The policies of the FDA, NMPA, EMA and of other regulatory authorities may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our drug candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad, particularly in China, where the regulatory environment is constantly evolving. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any regulatory approval that we may have obtained and we may not achieve or sustain profitability.
In addition, if we are able to obtain accelerated approval of any of our drug candidates, as we have done with the initial approval of BRUKINSA in the United States, the FDA would require us to conduct a confirmatory study to verify the predicted clinical benefit and may also require post-marketing safety studies. Other comparable regulatory authorities outside the United States, such as the NMPA or EMA, may have similar requirements. The results from the confirmatory study may not support the clinical benefit, which would result in the approval being withdrawn. While operating under accelerated approval, we will be subject to certain restrictions that we would not be subject to upon receiving regular approval.
If safety, efficacy, or other issues arise with any medical product that is used in combination with our drugs, we may be unable to market such drug or may experience significant regulatory delays or supply shortages, and our business could be materially harmed.
We plan to develop certain of our drug candidates for use as a combination therapy. If the FDA, NMPA, EMA or another comparable regulatory agency revokes its approval of another therapeutic we use in combination with our drug candidates, we will not be able to market our drug candidates in combination with such revoked therapeutic. If safety or efficacy issues arise with these or other therapeutics that we seek to combine with our drug candidates in the future, we may experience significant regulatory delays, and we may be required to redesign or terminate the applicable clinical trials. In addition, if manufacturing or other issues result in a supply shortage of any component of our combination drug candidates, we may not be able to complete clinical development of our drug candidates on our current timeline or at all, or we may experience disruptions in the commercialization of our approved drugs. For example, we have in-licensed drug candidates from third parties to conduct clinical trials in combination with our drug candidates. We may rely on those third parties to manufacture the in-licensed drug candidates and may not have control over their manufacturing process. If these third parties encounter any manufacturing difficulties, disruptions or delays and are not able to supply sufficient quantities of drug candidates, our drug combination study program may be delayed.
Reimbursement may be limited or unavailable for our drugs and drug candidates. Even if we are able to commercialize our drugs and any approved drug candidates, the drugs may become subject to unfavorable pricing regulations or third-party reimbursement practices, which could harm our business.
The regulations that govern regulatory approvals, pricing and reimbursement for new therapeutic products vary widely from country to country. Historically, products launched in the EU do not follow price structures of the U.S. and generally prices tend to be significantly lower. The EU provides options for its Member States to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. To obtain reimbursement or pricing approval, some of these countries may require the completion of clinical trials that compare the cost effectiveness of a particular product candidate to currently available therapies. A Member State may approve a specific price for the medicinal product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market.
Some countries require approval of the sale price of a drug before it can be marketed. In many countries, the pricing review period begins after marketing or licensing approval is granted. In some non-U.S. markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we might obtain regulatory approval for a drug in a particular country, but then be subject to price regulations that delay our commercial launch of the drug and negatively impact our revenues and results of operations.
Our ability to commercialize any drugs successfully also will depend in part on the extent to which reimbursement for these drugs and related treatments will be available on adequate terms, or at all, from government health administration authorities, private health insurers and other organizations. In the United States and markets in other countries, patients generally rely on third-party payors to reimburse all or part of the costs associated with their treatment. Adequate coverage and reimbursement from governmental healthcare programs, such as Medicare and Medicaid, and commercial payors is critical to new product acceptance. Sales of our product candidates will depend substantially, both domestically and abroad, on the extent to which the costs of our product candidates will be paid by health maintenance, managed care, pharmacy benefit and similar healthcare management organizations, or reimbursed by government health administration authorities, private health coverage insurers and other third-party payors.

A primary trend in the global healthcare industry is cost containment. Government authorities and these third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications.
In the United States, no uniform policy of coverage and reimbursement for drugs exists among third-party payors. As a result, obtaining coverage and reimbursement approval of a drug from a government or other third-party payor is a time-consuming and costly process that could require us to provide to each payor supporting scientific, clinical and cost-effectiveness data for the use of our drugs on a payor-by-payor basis, with no assurance that coverage and adequate reimbursement will be obtained. The principal decisions about reimbursement for new medicines are typically made by CMS. CMS decides whether and to what extent a new medicine will be covered and reimbursed under Medicare and private payors tend to follow CMS to a substantial degree. Factors payors consider in determining reimbursement are based on whether the product is: a covered benefit under its health plan; safe, effective and medically necessary; appropriate for the specific patient; cost-effective; and neither experimental nor investigational.
Coverage may be more limited than the purposes for which the medicine is approved by the FDA or comparable regulatory authorities in other countries. Even if we obtain coverage for a given drug, the resulting reimbursement rates might not be adequate for us to achieve or sustain profitability or may require co-payments that patients find unacceptably high. Additionally, third-party payors may not cover, or provide adequate reimbursement for, long-term follow-up evaluations required following the use of our drugs. Patients are unlikely to use our drugs and any approved drug candidates unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of the drug. Because some of our drugs and drug candidates have a higher cost of goods than conventional therapies and may require long-term follow-up evaluations, the risk that coverage and reimbursement rates may be inadequate for us to achieve profitability may be greater.
Net prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States. Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. We cannot be sure that reimbursement will be available for any product candidate that we commercialize and, if reimbursement is available, the level of reimbursement. In addition, many pharmaceutical manufacturers must calculate and report certain price reporting metrics to the government, such as average sales price (“ASP”) and best price. Penalties may apply in some cases when such metrics are not submitted accurately and timely. Further, these prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare programs.
Furthermore, there has been heightened governmental scrutiny recently over the manner in which drug manufacturers set prices for their marketed products. For example, there have been several recent Congressional inquiries, proposed bills or announced plans intended to, among other things, bring more transparency to drug pricing, set patient spending caps, reduce the cost of prescription drugs under Medicare, review the relationship between pricing and manufacturer’s patient programs, reform government program reimbursement methodologies for drug products, and allow import of lower-priced drugs from other countries. While some proposed measures may require additional authorization to become effective, Congress and the Trump administration have each indicated that it will continue to seek new legislative and/or administrative measures to control drug costs. We cannot be sure whether additional legislative changes will be enacted, or whether existing regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals of our drug candidates, if any, may be.
In the United States, since its enactment, there have been numerous judicial, administrative, executive, and legislative challenges to certain aspects of the Affordable Care Act (the “ACA”), and we expect there will be additional challenges and amendments to the ACA in the future. Various portions of the ACA are currently undergoing legal and constitutional challenges in the Fifth Circuit Court and the United States Supreme Court; the Trump Administration has issued various Executive Orders which eliminated cost sharing subsidies and various provisions that would impose a fiscal burden on states or a cost, fee, tax, penalty or regulatory burden on individuals, healthcare providers, health insurers, or manufacturers of pharmaceuticals or medical devices; and Congress has introduced several pieces of legislation aimed at significantly revising or repealing the ACA. It is unclear whether the ACA will be overturned, repealed, replaced, or further amended. We cannot predict what affect further changes to the ACA would have on our business.
Additionally, the current administration released a “Blueprint” to lower drug prices and reduce out of pocket costs of drugs that contains additional proposals to increase manufacturer competition, increase the negotiating power of certain federal healthcare programs, incentivize manufacturers to lower the list price of their products and reduce the out of pocket costs of drug products paid by consumers. HHS has already started the process of soliciting feedback on some of these measures and, at the same time, is immediately implementing others under its existing authority. It is not clear what effect these measures may have on our business if we receive coverage for our drugs and drug candidates

In China, drug prices are typically lower than in the United States and Europe, and until recently, the market has been dominated by generic drugs. The PRC Ministry of Human Resources and Social Security or provincial or local human resources and social security authorities, together with other government authorities, review the inclusion or removal of drugs from China’s National Drug Catalog for Basic Medical Insurance, Work-related Injury Insurance and Maternity Insurance, or the National Reimbursement Drug List (the "NRDL"), or provincial or local medical insurance catalogues for the National Medical Insurance Program regularly, and the tier under which a drug will be classified, both of which affect the amounts reimbursable to program participants for their purchases of those drugs. There can be no assurance that our drugs and any approved drug candidates will be included in the NRDL or provincial reimbursements lists, or if they are, that they will be included at a price that allows us to be commercially successful. Products included in the NRDL have been typically generic and essential drugs. Innovative drugs similar to our drugs and drug candidates have historically been more limited on their inclusion in the NRDL due to the affordability of the government’s Basic Medical Insurance, although this has been changing in recent years.
In addition, in January 2019, the Chinese government launched a national program for volume-based, centralized drug procurement with minimum quantity commitments in an attempt to negotiate lower prices from drug manufacturers and reduce the price of drugs. The program was initially rolled out in 11 pilot cities and was expanded nationwide in September 2019. Under the program, one of the key determining factors for a successful bid is the price. The government will award a contract to the lowest bidders who are able to satisfy the quality and quantity requirements. The successful bidders will be guaranteed a sale volume for at least a year. A volume guarantee gives the winner an opportunity to gain or increase market share. The volume guarantee is intended to make manufacturers more willing to cut their prices to win a bid. It may also enable manufacturers to lower their distribution and commercial costs. Many types of drugs are covered under the program, including drugs made by international pharmaceutical companies and generics made by domestic Chinese manufacturers. For example, in January 2020, ABRAXANE and its generic forms were included in the program. We won the bid and became one of the three companies who were awarded a government contract, with a price that will be significantly lower than the price that we have been charging in 2019 and into 2020. Once ABRAXANE is included in the centralized procurement process, we anticipate that demand will increase significantly, which could have a material impact on our commercialization efforts and results of operations. Moreover, the program may change how generic drugs are priced and procured in China and is likely to accelerate the replacement of originator drugs with generics. We cannot be sure whether there will be any changes to the program in the future. The implementation of the program may negatively impact our existing commercial operations in China as well as our strategies on how to commercialize our drugs in China, especially if one of our drugs is included in the program but does not win the bid, which could have a material adverse effect on our business, financial condition and results of operations.
Increasingly, third-party payors are requiring that companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. We cannot be sure that reimbursement will be available for any drug that we commercialize and, if reimbursement is available, what the level of reimbursement will be. Reimbursement may impact the demand for, or the price of, any drug which we commercialize. Obtaining or maintaining reimbursement for our drugs may be particularly difficult because of the higher prices often associated with drugs administered under the supervision of a physician. If reimbursement is not available or is available only to limited levels, we may not be able to successfully commercialize any drug and drug candidate that we in-license or successfully develop.
There may be significant delays in obtaining reimbursement for approved drugs, and coverage may be more limited than the purposes for which the drug is approved by the FDA or other comparable regulatory authorities outside the United States. Moreover, eligibility for reimbursement does not imply that any drug will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution. Interim payments for new drugs, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Payment rates may vary according to the use of the drug and the clinical setting in which it is used, may be based on payments allowed for lower cost drugs that are already reimbursed, and may be incorporated into existing payments for other services. Net prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors and by any future weakening of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States. Our inability to promptly obtain coverage and profitable payment rates from both government-funded and private payors for our drugs and any new drugs that we develop could have a material adverse effect on our business, our operating results, and our overall financial condition.
We intend to seek approval to market our drug candidates in the United States, China, Europe and in other jurisdictions. In some non-U.S. countries, for example those in the EU, the pricing of drugs and biologics is subject to governmental control, which can take considerable time even after obtaining regulatory approval. Market acceptance and sales of our drugs will depend significantly on the availability of adequate coverage and reimbursement from third-party payors for drugs and may be affected by existing and future health care reform measures.

Recently enacted and future legislation may increase the difficulty and cost for us to obtain regulatory approval of and commercialize our drugs and drug candidates and affect the prices we may obtain.
In the United States, China, the EU and some other jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding healthcare that could prevent or delay regulatory approval of our drug candidates, restrict or regulate post-approval activities and affect our ability to profitably sell our drugs and any drug candidates for which we obtain regulatory approval. We expect that healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the price that we receive for any approved drug. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our drugs and drug candidates.
Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities for pharmaceutical products. We cannot be sure whether additional legislative changes will be enacted, or whether FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the regulatory approvals of our drug candidates, if any, may be.
In recent years, there have been and will likely continue to be efforts to enact administrative or legislative changes to healthcare laws and policies, including modification, repeal, or replacement of all, or certain provisions of, the ACA. The implications of the ACA, its possible repeal, any legislation that may be proposed to replace the ACA, modifications to the implementation of the ACA, and the political uncertainty surrounding any repeal or replacement legislation for our business and financial condition, if any, are not yet clear.
Risks Related to Our Financial Position and Need for Additional Capital
We have a limited operating history, which may make it difficult to evaluate our current business and predict our future performance.
We are a commercial-stage biotechnology company formed in October 2010. Our operations to date have focused on organizing and staffing our company, business planning, raising capital, establishing our intellectual property portfolio, conducting preclinical studies and clinical trials of our drug candidates, developing and operating internal manufacturing capabilities, and the commercialization of our in-licensed and internally-discovered drugs. We have limited experience in completing large-scale, pivotal or registrational clinical trials and obtaining, maintaining or expanding regulatory approvals for our drugs and drug candidates. Additionally, we have limited experience in manufacturing, sales, marketing or distribution of pharmaceutical products. We have two internally developed drugs approved for commercial sale and have only generated limited revenue from internally developed product sales. Since September 2017, we have generated revenues from the sale of drugs in China licensed from BMS and we expect to begin generating revenues from our internally developed products in 2020. Our limited operating history, particularly in light of the rapidly evolving cancer treatment field, may make it difficult to evaluate our current business and reliably predict our future performance. We may encounter unforeseen expenses, difficulties, complications, delays and other known and unknown factors. If we do not address these risks and difficulties successfully, our business will suffer.
We have incurred significant net losses since our inception and anticipate that we will continue to incur net losses for the foreseeable future and may never become profitable.
Investment in pharmaceutical drug development is highly speculative. It entails substantial upfront capital expenditures and significant risk that a drug candidate will fail to gain regulatory approval or become commercially viable. We continue to incur significant expenses related to our ongoing operations. As a result, we have incurred losses in each period since our inception, except in the third quarter of 2017, when we were profitable due to revenue recognized from an up-front license fee from BMS. As of December 31, 2019 and 2018, we had an accumulated deficit of $2.0 billion and $1.0 billion, respectively. Substantially all of our operating losses have resulted from costs incurred in connection with our research and development programs and from selling, general and administrative expenses associated with our operations.
We expect to continue to incur losses for the foreseeable future, and we expect these losses to increase in the near term as we continue and expand our development of, and seek regulatory approvals for, our drug candidates, and our manufacturing facilities, commercialize our drugs and launch new drugs, if approved, maintain and expand regulatory approvals, contribute up to $1.25 billion to the global development of 20 Amgen pipeline assets, and commercialize the drugs that we have licensed from BMS and drugs that we have the right to commercialize under our collaboration with Amgen in China and any other drugs that we may successfully develop or license. Typically, it takes many years to develop one new drug from the time it is discovered to when it is available for treating patients. In addition, we will continue to incur costs associated with operating as a public company in the United States and Hong Kong. We will also incur costs in support of our growth as a commercial-stage

global biotechnology company. The size of our future net losses will depend, in part, on the number and scope of our drug development programs and the associated costs of those programs, the cost of our manufacturing activities, the cost of commercializing our approved products, our ability to generate revenues and the timing and amount of milestones and other payments we make or receive with arrangements with third parties. If any of our drug candidates fail in clinical trials or do not gain regulatory approval, or if approved, fail to achieve market acceptance, we may never become profitable. Even if we achieve profitability in the future, we may not be able to sustain profitability in subsequent periods. Our failure to become and remain profitable would decrease the value of our company and could impair our ability to raise capital, maintain our research, development, manufacturing and commercialization efforts, expand our business or continue our operations.
We may need to obtain additional financing to fund our operations, and if we are unable to obtain such financing, we may be unable to complete the further development and commercialization of our drugs and drug candidates.
Our drugs and drug candidates will require the completion of clinical development, regulatory review, scale up and availability of manufacturing resources, significant marketing efforts and substantial investment before they can provide us with product sales revenue. Our operations have consumed substantial amounts of cash since inception. Our operating activities used $750.3 million and $547.7 million of net cash during the years ended December 31, 2019 and 2018, respectively. We recorded negative net cash flows from operating activities in 2019 and 2018 primarily due to our net losses of $950.6 million and $674.0 million, respectively. Although we recorded positive net cash flows from operating activities in 2017, primarily due to the upfront fees received from the BMS collaboration, we cannot assure you that we will be able to generate positive cash flows from operating activities in the future. In January 2020, we received gross proceeds of approximately $2.78 billion from the issuance of our ordinary shares in the form of ADSs to Amgen. Under the collaboration with Amgen, we will equally share profits/losses with Amgen for Amgen’s oncology products in China during each product’s respective commercialization period and will also be eligible to receive royalties on sales of Amgen’s products in China or outside of China in the future, based on specified terms.
Our liquidity and financial condition may be materially and adversely affected by the negative net cash flows, and we cannot assure you that we will have sufficient cash from other sources to fund our operations. If we resort to other financing activities to generate additional cash, we will incur financing costs and we cannot guarantee that we will be able to obtain the financing on terms acceptable to us, or at all, and if we raise financing by issuing further equity securities your interest in our company may be diluted. If we have negative operating cash flows in the future, our liquidity and financial condition may be materially and adversely affected.
We expect to continue to spend substantial amounts on drug discovery, advancing the clinical development of our drug candidates, contributing to the global development of 20 Amgen pipeline assets, developing our manufacturing capabilities and securing drug supply, and launching and commercializing our and our collaborators' drugs and any additional drug candidates for which we receive regulatory approval, including building and maintaining a commercial organization to address markets in China, the United States and other countries.
Since September 2017, we have generated revenues from the sale of drugs in China licensed from BMS, and we expect to begin generating revenues from our internally developed products in 2020. These revenues are not sufficient to support our operations. Although it is difficult to predict our liquidity requirements, based upon our current operating plan, we believe that we have sufficient cash, cash equivalents and short-term investments to meet our projected operating requirements for at least the next 12 months. However, we believe that our existing cash, cash equivalents and short-term investments may not be sufficient to enable us to complete all global development or commercially launch all of our current drugs and drug candidates for the currently anticipated indications and to invest in additional programs. Accordingly, we may require further funding through public or private offerings, debt financing, collaboration and licensing arrangements or other sources. Our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement and involves risks and uncertainties, and actual results could vary as a result of a number of factors, including the factors discussed elsewhere in this “Risk Factors” section. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we currently expect. Our future funding requirements will depend on many factors, including:
our ability to successfully market our approved drugs;
the progress, timing, scope and costs of our clinical trials, including the ability to timely enroll patients in our planned and potential future clinical trials;
the outcome, timing and cost of regulatory approvals of our drug candidates;
the number and characteristics of drugs and drug candidates that we may in-license and develop;

the amount and timing of the development, milestone and royalty payments we receive from our collaborators;
the cost of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights;
selling and marketing costs associated with our drugs and any future drug candidates that may be approved, including the cost and timing of expanding our marketing and sales capabilities;
the terms and timing of any potential future collaborations, licensing or other arrangements that we may establish;
cash requirements of any future acquisitions, licensing and/or the development of other drug candidates;
the cost and timing of development and completion of commercial-scale internal or outsourced manufacturing activities; and
our headcount growth and associated costs.
Adequate additional funding may not be available to us on acceptable terms, or at all. If we are unable to raise capital when needed or on attractive terms, we would be forced to delay, reduce or eliminate our research and development programs or future commercialization efforts. Our inability to obtain additional funding when we need it could seriously harm our business.
Raising additional capital may cause dilution to our shareholders, restrict our operations or require us to relinquish rights to our technologies or drug candidates.
We may seek additional funding through a combination of equity offerings, debt financings, collaborations and licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms may include liquidation or other preferences that adversely affect your rights as a holder of our ordinary shares and/or ADSs. The incurrence of additional indebtedness or the issuance of certain equity securities could result in increased fixed payment obligations and could also result in certain additional restrictive covenants, such as limitations on our ability to incur additional debt or issue additional equity, limitations on our ability to acquire or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. In addition, issuance of additional equity securities, or the possibility of such issuance, may cause the market price of our ADSs and/or ordinary shares to decline. In the event that we enter into collaborations or licensing arrangements in order to raise capital, we may be required to accept unfavorable terms, including relinquishing or licensing to a third party on unfavorable terms our rights to technologies or drug candidates that we otherwise would seek to develop or commercialize ourselves or potentially reserve for future potential arrangements when we might be able to achieve more favorable terms.
Fluctuations in exchange rates could result in foreign currency exchange losses and could materially reduce the value of your investment.
We incur portions of our expenses, and derive revenues, in currencies other than the U.S. dollar or Hong Kong dollar, in particular, the RMB, the Euro, and Australian dollar. As a result, we are exposed to foreign currency exchange risk as our results of operations and cash flows are subject to fluctuations in foreign currency exchange rates. We do not regularly engage in hedging transactions to protect against uncertainty in future exchange rates between particular foreign currencies and the U.S. dollar. A decline in the value of the U.S. dollar against currencies in countries in which we conduct clinical trials could have a negative impact on our research and development costs. We cannot predict the impact of foreign currency fluctuations, and foreign currency fluctuations in the future may adversely affect our financial condition, results of operations and cash flows.
The value of the RMB against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in political and economic conditions and the foreign exchange policy proposed or adopted by the PRC, Australia and other non-U.S. governments. It is difficult to predict how market forces or PRC, Australia, other non-U.S. governments and U.S. government policies may impact the exchange rate of RMB and the U.S. dollar or any other currencies in the future. There remains significant international pressure on the PRC government to adopt a more flexible currency policy, including from the U.S. government, which has threatened to label China as a “currency manipulator,” which could result in greater fluctuation of the RMB against the U.S. dollar.
Substantially all of our revenues are denominated in U.S. dollars and RMB, and our costs are denominated in U.S. dollars, Australian dollars, RMB and Euro, and a large portion of our financial assets and a significant portion of our debt is denominated in U.S. dollars and RMB. Any significant revaluation of the RMB may materially reduce any dividends payable on our ordinary shares and/or ADSs in U.S. dollars. To the extent that we need to convert U.S. dollars into RMB for our operations, appreciation of the RMB against the U.S. dollar would have an adverse effect on the RMB amount we would receive. Conversely, if we decide to convert RMB into U.S. dollars for the purpose of making payments for dividends on our

ADSs or for other business purposes, appreciation of the U.S. dollar against the RMB would have a negative effect on the U.S. dollar amount we would receive.
In addition, there are limited instruments available for us to reduce our foreign currency risk exposure at reasonable costs. Furthermore, we are also currently required to obtain the State Administration of Foreign Exchange ("SAFE")'s approval before converting significant sums of foreign currencies into RMB. All of these factors could materially and adversely affect our business, financial condition, results of operations and prospects, and could reduce the value of, and dividends payable on, our ordinary shares and/or ADSs in foreign currency terms.
Our business, profitability and liquidity may be adversely affected by deterioration in the credit quality of, or defaults by, our distributors and customers, and an impairment in the carrying value of our short-term investments could negatively affect our consolidated results of operations.
We are exposed to the risk that our distributors and customers may default on their obligations to us as a result of bankruptcy, lack of liquidity, operational failure or other reasons. As we continue to expand our business, the amount and duration of our credit exposure will be expected to increase over the next few years, as will the breadth of the entities to which we have credit exposure. Although we regularly review our credit exposure to specific distributors and customers that we believe may present credit concerns, default risks may arise from events or circumstances that are difficult to detect or foresee.
Also, the carrying amounts of cash and cash equivalents, restricted cash and short-term investments represent the maximum amount of loss due to credit risk. We had cash and cash equivalents of $618.0 million and $712.9 million, restricted cash of $2.8 million and $27.8 million and short-term investments of $364.7 million and $1.1 billion at December 31, 2019 and 2018, respectively, most of which are deposited in financial institutions outside of China. Although our cash and cash equivalents in China are deposited with various major reputable financial institutions, the deposits placed with these financial institutions are not protected by statutory or commercial insurance. In the event of bankruptcy of one of these financial institutions, we may be unlikely to claim our deposits back in full. As of December 31, 2019 and 2018, our short-term investments consisted of U.S. Treasury securities.
Although we believe that U.S. Treasury securities are of high credit quality, concerns about, or a default by, one or more institutions in the market could lead to significant liquidity problems, losses or defaults by other institutions, which in turn could adversely affect us.
Risks Related to Our Intellectual Property

A significant portion of our intellectual property portfolio currently comprises pending patent applications that have not yet been issued as granted patents and if our pending patent applications fail to issue our business will be adversely affected.

If we are unable to obtain and maintain patent protection for our technologydrug candidates and drugs our competitors could develop and commercialize technology and drugs similarthrough intellectual property rights, or identical to ours, and our ability to successfully commercialize our technology and drugsif the scope of such intellectual property rights obtained is not sufficiently broad, third parties may be adversely affected.

compete directly against us.

Our success depends in large part on our ability to obtain and maintain patent protection in the United States, the PRC and other countries with respect toprotect our proprietary technology and drug candidates. As of March 21, 2017, we own eight issued U.S. patentscandidates and eight pending U.S.drugs from competition by obtaining, maintaining and enforcing our intellectual property rights, including patent applications as well as corresponding patents and patent applications internationally. In addition, we own 13 pending international patent applications under the PCT, which we plan to file nationally in the United States and other jurisdictions. With respect to any issued patents in the United States and Europe, we may be entitled to obtain a patent term extension to extend the patent expiration date provided we meet the applicable requirements for obtaining such patent term extensions.rights. We have soughtseek to protect our proprietary positionthe drugs, drug candidates and technology that we consider commercially important by filing patent applications in the United States, the PRC and other countries, related to novel technologies and drug candidates that we consider are important to our business.relying on trade secrets or pharmaceutical regulatory protection or employing a combination of these methods. This process is expensive and time-consuming, and we may not be able to file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection.

The patent position of biotechnologyprosecution process is expensive, time-consuming and pharmaceutical companies generally is highly uncertain, involves complex, legal and factual questions and haswe may not be able to file, prosecute, maintain, enforce or license all necessary or desirable patents and/or patent applications at a reasonable cost or in recent years been the subject of much litigation.a timely manner. As a result, the issuance, scope, validity, enforceabilitywe may not be able to prevent competitors from developing and commercial value of our patent rights are highly uncertain. Our pendingcommercializing competitive drugs in all such fields and futureterritories.
Patents may be invalidated and patent applications may not resultbe granted for a number of reasons, including known or unknown prior art, deficiencies in patents being issued which protect our technology or drug candidates or which effectively prevent others from commercializing competitive technologies and drug candidates. Changes in either the patent lawsapplications or interpretationthe lack of novelty of the patent laws in the United States and other countries may diminish the valueunderlying invention or technology. It is also possible that we will fail to identify patentable aspects of our patentsresearch and development output in time to obtain patent protection. Although we enter into non-disclosure and confidentiality agreements with parties who have access to confidential or narrow the scopepatentable aspects of our research and development output, such as our employees, corporate collaborators, outside scientific collaborators, contract manufacturers, consultants, advisors and any other third parties, any of these parties may breach such agreements and disclose such output before a patent application is filed, thereby jeopardizing our ability to seek patent protection. PublicationsIn addition, publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing, or in some cases, not at all. Therefore, we cannot be certain that we were the first to make the inventions claimed in our patents or pending

patent applications or that we were the first to file for patent protection of such inventions. AssumingFurthermore, the other requirements for patentability are met,PRC and, recently, the United States have adopted the “first-to-file” system under which whoever first to filefiles a patent application will be awarded the patent if all other patentability requirements are met. Under the first-to-file system, third parties may be granted a patent relating to a technology which we invented.
In addition, under the PRC Patent Law, any organization or individual that applies for a patent in a foreign country for an invention or utility model accomplished in China is entitledrequired to report to the patent. Under the Leahy-Smith America Invents Act enactedNational Intellectual Property Administration, or NIPA, for security examination. Otherwise, if an application is later filed in 2011, the United States moved to this first-to-file system in early 2013 from the previous system under which the first to make the claimed invention was entitled to the patent. We may become involved in interferenceinter partes review, post grant review,ex parte reexamination, derivation, opposition or similar other proceedings challenging our patent rights orChina, the patent rights of others. An adverse determinationright will not be granted.
The coverage claimed in any such proceeding could reduce the scope of, or invalidate, oura patent rights, allow third parties to commercialize our technology or drug candidates and compete directly with us, or result in our inability to manufacture or commercialize drug candidates without infringing third-party patent rights.

        Thereapplication can be no assurance that our pendingsignificantly reduced before the patent is issued, and its scope can be reinterpreted after issuance. Even if patent applications will result in issued patentswe license or own currently or in the United States or non-U.S. jurisdictions in which such applications are pending. Even if patents do issue on any of these applications, there can be no assurance that a third party will not challenge their validity or that we will obtain sufficient claim scope in those patents to prevent a third party from competing successfully with our drug candidates. Even if our patent applicationsfuture issue as patents, they may not issue in a form that will provide us with any meaningful protection, prevent competitors or other third parties from competing with us, or otherwise provide us with any competitive advantage. Our competitors may be able to circumventIn addition, the patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions, and has been the subject of much litigation in recent years. As a result, the issuance, scope, validity, enforceability and commercial value of our patents by developing similar or alternative technologies or drug candidates in a

patent rights are highly uncertain.

non-infringing manner. The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our owned and licensed patents may be challenged in the courts or patent offices in the United States, PRC and abroad.other countries. We may be subject to a third-party preissuance submission of prior art to the United States Patent and Trademark Office (the "USPTO") or become involved in opposition, derivation, revocation, re-examination, post-grant and inter partes review, or interference proceedings or similar proceedings in foreign jurisdictions challenging our patent rights or the patent rights of others. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate, our patent rights, allow third parties to commercialize our technology or drugs or drug candidates and compete directly with us without payment to us, or result in our inability to manufacture or commercialize drugs or drug candidates without infringing, misappropriating or otherwise violating third-party patent rights. Moreover, we may have to participate in interference proceedings declared by the USPTO to determine priority of invention or in post-grant challenge proceedings, such as oppositions in a foreign patent office, that challenge the priority of our invention or other features of patentability of our patents and patent applications. Such challenges may result in loss of patent rights, loss of exclusivity, or in patent claims being narrowed, invalidated, or held unenforceable, which could limit our ability to stop or prevent us from stopping others from using or commercializing similar or identical technology and drug candidates,products, or limit the duration of the patent protection of our technology, drugs, and drug candidates. Such proceedings also may result in substantial costs and require significant time from our scientists and management, even if the eventual outcome is favorable to us. Consequently, we do not know whether any of our technology or drugs or drug candidates will be protectable or remain protected by valid and enforceable patents. Our competitors or other third parties may be able to circumvent our patents by developing similar or alternative technologies or products in a non-infringing manner.

Furthermore, although various extensions may be available, the life of a patent and the protection it affords, is limited. For example, the approved cancer therapies we have licensed from BMS in China, ABRAXANE, REVLIMID, and VIDAZA, face or are expected to face competition from generic medications, and we may face similar competition for any approved drugs even if we successfully obtain patent protection. Manufacturers of generic drugs may challenge the scope, validity or enforceability of our patents in court, and we may not be successful in enforcing or defending those intellectual property rights and, as a result, may not be able to develop or market the relevant product exclusively, which would have a material adverse effect on any potential sales of that product. The issued patents and pending patent applications, if issued, for our drugs and drug candidates are expected to expire on various dates as described in “Part I-Item 1-Business-Intellectual Property” of our Annual Report on Form 10-K for the year ended December 31, 2019. Upon the expiration of our issued patents or patents that may issue from our pending patent applications, we will not be able to assert such patent rights against potential competitors and our business and results of operations may be adversely affected.
Given the amount of time required for the development, testing and regulatory review of new drug candidates, patents protecting such drug candidates might expire before or shortly after such drug candidates are commercialized. As a result, our patents and patent portfolioapplications may not provide us with sufficient rights to exclude others from commercializing drug candidatesproducts similar or identical to ours.

Moreover, some of our patents and patent applications are, and may in the future be, co-owned with or licensed from third parties. If we are unable to obtain an exclusive license to any such third-party co-owners’ interest in such patents or patent applications, such co-owners may be able to license their rights to other third parties, including our competitors, and our competitors could market competing products and technology. In addition, we may need the cooperation of any such co-owners or the licensors of our patents in order to enforce such patents against third parties, and such cooperation may not be provided to us. Any of the foregoing could have a material adverse effect on our competitive position, business, financial conditions, results of operations and prospects.


We may not be able to protect our intellectual property rights throughout the world.

Filing, prosecuting, maintaining and defending patents on drugs or drug candidates in all countries throughout the world could be prohibitively expensive for us, and our intellectual property rights in some non-U.S. countries can have a different scope and strength than do those in the United States. In addition, the laws of certain non-U.S. countries do not protect intellectual property rights to the same extent as U.S. federal and state laws do. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States, or from selling or importing drugs made using our inventions in and into the United States or non-U.S. jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own drugs and further, may export otherwise infringing drugs to non-U.S. jurisdictions where we have patent protection, but where enforcement rights are not as strong as those in the United States. These drugs may compete with our drugs and drug candidates and our patent rights or other intellectual property rights may not be effective or adequate to prevent them from competing.

In addition, we may not be able to enforce patents that we in-license from third parties, who may delay or decline to enforce patents in the licensed territory.

We currently hold issued trademark registrations and have trademark applications pending, any of which may be the subject of a governmental or third-party objection, which could prevent the maintenance or issuance of the same. If we are unsuccessful in obtaining trademark protection for our primary brands, we may be required to change our brand name,names, which could materially adversely affect our business. Moreover, as our products mature, our reliance on our trademarks to differentiate us from our competitors will increase, and as a result, if we are unable to prevent third parties from adopting, registering or using trademarks and trade dress that infringe, dilute or otherwise violate our trademark rights, our business could be materially adversely affected.

Many companies have encountered significant problems in protecting and defending intellectual property rights in certain jurisdictions, including China. The legal systems of some countries do not favor the enforcement of patents, trade secrets and other intellectual property, particularly those relating to biopharmaceutical products, which could make it difficult in those jurisdictions for us to stop the infringement or misappropriation of our patents or other intellectual property rights, or the marketing of competing drugs in violation of our proprietary rights.

        Proceedings to enforce our patent and other intellectual property rights in non-U.S. jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business.

        Furthermore, such proceedings could put our patents at risk of being invalidated, held unenforceable, or interpreted narrowly, could put our patent applications at risk of not issuing, and could provoke third parties to assert claims of infringement or misappropriation against us.

We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop.


We may become involved in lawsuits to protect or enforce our intellectual property, which could be expensive, time consuming and unsuccessful. Our patent rights relating to our drugs and drug candidates could be found invalid or unenforceable if challenged in court or before the U.S. Patent and Trademark OfficeUSPTO or comparable non-U.S. authority.

Competitors may infringe our patent rights or misappropriate or otherwise violate our intellectual property rights. To counter infringement or unauthorized use, litigation may be necessary in the future to enforce or defend our intellectual property rights, to protect our trade secrets or to determine the validity and scope of our own intellectual property rights or the proprietary rights of others. This can be expensive and time consuming. Any claims that we assert against perceived infringers could also provoke these parties to assert counterclaims against us alleging that we infringe their intellectual property rights. Many of our current and potential competitors have the ability to dedicate substantially greater resources to enforce and/or defend their intellectual property rights than we can. Accordingly, despite our efforts, we may not be able to prevent third parties from infringing upon or misappropriating our intellectual property. Litigation could result in substantial costs and diversion of management resources, which could harm our business and financial results. In addition, in an infringement proceeding, a court may decide that patent rights or other intellectual property rights owned by us are invalid or unenforceable, or may refuse to stop the other party from using the technology at issue on the grounds that our patent rights or other intellectual property rights do not cover the technology in question. An adverse result in any litigation proceeding could put our patent, as well as any patents that may issue in the future from our pending patent applications, at risk of being invalidated, held unenforceable or interpreted narrowly. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation.

        If we initiate legal proceedings against a third party to enforce our patent, or any patents that may issue in the future from our patent applications, that relates to one of our drug candidates, the defendant could counterclaim that such patent rights are invalid or unenforceable.

In patent litigation in the United States, defendant counterclaims alleging invalidity or unenforceability are commonplace, and there are numerous grounds upon which a third party can assert invalidity or unenforceability of a patent. Third parties may also raise similar claims before administrative bodies in the United States or abroad, even outside the context of litigation. Such mechanisms includeex parte re-examination,inter partes review, post-grant review, derivation and equivalent proceedings in non-U.S. jurisdictions, such as opposition proceedings. Such proceedings could result in revocation or amendment to our patents in such a way that they no longer cover and protect our drugs or drug candidates. The outcome following legal assertions of invalidity and unenforceability is unpredictable. With respect to the validity of our patents, for example, we cannot be certain that there is no invalidating prior art of which we, our patent counsel, and the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal assertion of invalidity and/or unenforceability, we would lose at least part, and perhaps all, of the patent protection on our drugs or drug candidates. Such a loss of patent protection could have a material adverse impact on our business.


We may not be able to prevent misappropriation of our trade secrets or confidential information, particularly in countries where the laws may not protect those rights as fully as in the United States. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation.

We may be subject to claims challenging the inventorship of our patents and other intellectual property.

        Although we are not currently experiencing any claims challenging the inventorship of our patents or ownership of our intellectual property, we may in the future be subject to claims that former employees, collaborators or other third parties have an interest in our patents or other intellectual


property as inventors or co-inventors. For example, we may have inventorship disputes arise from conflicting obligations of consultants or others who are involved in developing our drug candidates. Litigation may be necessary to defend against these and other claims challenging inventorship. If we fail in defending any such claims, in addition to paying monetary damages, we may lose rights such as exclusive ownership of, or right to use, our patent rights or other intellectual property. Such an outcome could have a material adverse effect on our business. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management and other employees.

If we are sued for infringing intellectual property rights of third parties, such litigation could be costly and time consuming and could prevent or delay us from developing or commercializing our drugs or drug candidates.

Our commercial success depends in part on our avoiding infringement of the valid patents and other intellectual property rights of third parties. We are aware of numerous issued patents and pending patent applications belonging to third parties that exist in fields of our drugs and drug candidates. There may also be third-party patents or patent applications of which we are currently unaware, and given the dynamic area in which we operate, additional patents are likely to issue that relate to aspects of our business. There is a substantial amount of litigation and other claims and proceedings involving patent and other intellectual property rights in the biotechnology and pharmaceutical industries includinginter partes review, post grant review, interference andex parte reexamination proceedings before the USPTO or oppositions and other comparable proceedings in non-U.S. jurisdictions. Numerous issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we are developing drug candidates.generally. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that our drugs and drug candidates may give rise to claims of infringement of the patent rights of others.

Third parties may assert that we are employingusing technology in violation of their patent or other proprietary technology without authorization. Thererights. Defense of these claims, regardless of their merit, could involve substantial litigation expense and divert our technical personnel, management personnel, or both from their normal responsibilities. Even in the absence of litigation, we may be third-party patents of which we are currently unaware with claimsseek to materials, formulations, methods of manufacture or methods for treatment related to the use or manufacture of our drug candidates. Because patent applications can take many years to issue, there may be currently pending patent applications which may later result in issued patents that our drug candidates may infringe. In addition,obtain licenses from third parties may obtain patents into avoid the futurerisks of litigation, and claim that use of our technologies infringes upon these patents. If any third-party patents were held by a court of competent jurisdiction to cover the manufacturing process of any of our drug candidates, any molecules formed during the manufacturing process or any final product itself, the holders of any such patents may be able to prevent us from commercializing such drug candidate unless we obtainif a license under the applicable patents, or until such patents expire or they are finally determined to be held invalid or unenforceable. Similarly, if any third-party patent were held by a court of competent jurisdiction to cover aspects of our formulations, processes for manufacture or methods of use, including combination therapy or patient selection methods, the holders of any such patent may be able to block our ability to developis available, it could impose costly royalty and commercialize the applicable drug candidate unless we obtain a license, limit our uses, or until such patent expires or is finally determined to be held invalid or unenforceable. In either case, such a license may not be availableother fees and expenses on commercially reasonable terms or at all.

        Thirdus.

If third parties who bring successful claims against us for infringement of their intellectual property rights, we may obtainbe subject to injunctive or other equitable relief, which could prevent us from developing and commercializing one or more of our drugs and drug candidates. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from our business. In the event of a successful claim against us of infringement or misappropriation, againstor a settlement by us of any such claims, we may have to pay substantial damages, including treble damages and attorneys'attorneys’ fees in the case of willful infringement, obtain one or more licenses from third parties, pay royalties or redesign our infringing drugs and drug candidates, which may be impossible or require substantial time and monetary expenditure.cost. In the event of an adverse result in any such litigation, or even in the absence of litigation, we may need to obtain licenses from third parties to advance our research or allow commercialization of our drugs or drug candidates. We cannot predict whether any requiredAny such license would be available at all or whether it wouldmight not be available on commercially reasonable terms and we may fail to obtain any of these licenses


on commercially reasonable terms, ifor at all. In the event that we are unable to obtain such a license, we would be unable to further develop and commercialize one or more of our drug and drug candidates, which could harm our business significantly. We may also elect to enter into license agreements in order to settle patent infringement claims or to resolve disputes prior to litigation, and any such license agreements may require us to pay royalties and other fees that could significantly harm our business.

        Specifically, we

We are aware of three U.S. patents owned by Ono Pharmaceutical Co., or Ono, and licensed to Bristol-Myers Squibb Co., or BMS,with claims covering certain antibodies that are relevant to our BGB-A317 drug candidate. Thesetislelizumab for which patents are expected to expire in 2023 2023 and 2024, respectively. In patent infringement actions filed in Delaware Federal District court, BMS and Ono alleged that Merck & Co.'s KEYTRUDA product, a humanized anti-PD-1 antibody is infringing these U.S. patents. Although Merck challenged the validityor 2024; complexes of these patents, Merck recently settled this litigation with BMS and Ono resulting in Merck taking a license from BMS and Ono. All these three patents remain presumed valid and enforceable. Merck also filed an opposition proceeding challenging a corresponding European patent at the European Patent Office, or EPO. The EPO's Opposition Division disagreed with Merck's arguments and maintained the European patent in the form in which it was granted. Merck appealed the decision, but recently withdrew its appeal. If the validity of the relevant claims in these U.S. patents is upheld and our BGB-A317 drug candidate is approved for sale in the United States before the expiration of these patents, then we will need a license from BMS in order to commercialize our BGB-A317 drug candidate in the United States prior to their expiration. In addition, depending upon circumstances, we may need a license for jurisdictions outside the United States where we wish to commercialize BGB-A317 before the expiration of a corresponding patent covering BGB-A317. There can be no assurance that we will be able to obtain such a license, which could materially and adversely affect our business.

        In addition, we are aware of a U.S. patent owned by Pharmacyclics, Inc., which was acquired by AbbVie, Inc., with certain claims directed to a complex of an irreversible BTK inhibitor having a covalent bondinhibitors that are relevant to a cysteine residue of a BTK. ThisBRUKINSA for which the patent is expected to expire in 2027.2027; and the use of PARP inhibitors to treat certain cancers that are relevant to pamiparib for which patents are expected to expire between 2027 and 2031. We are also aware of issued patents in Europe and China relevant to pamiparib. Although we believe that the relevant claims of the patent relevant to our BGB-3111 drug candidatethese patents would likely be held invalid, we cannotcan provide any assurancesno assurance that a court or an administrative agency would agree with our assessment. If the validity of the relevant claims in question isof one or more of these patents were to be upheld upon a validity challenge, and BGB-3111 isour related drug or drug candidate was to be approved for sale in the United States before the expiration of the U.S. patent, thenrelevant patents, we would need a license in order to commercialize BGB-3111the drug or drug candidate in the United States.States before the expiration of the relevant patents. In addition, depending upon the circumstances, we may need a licenselicenses for jurisdictions outside of the United States where we wish to commercialize BGB-3111a particular drug or drug candidate before the expiration of a corresponding patentpatents covering BGB-3111. Howeverthat drug or drug candidate. In such cases, we can provide no assurance that we would be able to obtain a license may not be availableor licenses on commercially reasonable terms or at all, which could materially and adversely affect our business.

        We are also aware of three U.S. patents, owned or licensed by KuDOS Pharmaceuticals, Ltd., which was acquired by AstraZeneca PLC, with claims directed to using PARP inhibitors to treat cancers with certain defects in homologous recombination including, in some cases, a BRCA1 or BRCA2 mutation. These patents are expected to expire between 2027 and 2031 in the United States. Although we believe that the claims of these patents relevant to our BGB-290 drug candidate would likely be held invalid, we cannot provide any assurances that a court or an administrative agency would agree with our assessment. While we are currently conducting and plan to conduct studies that include cancer patients with a BRCA1 or BRCA2 mutation, we are uncertain whether BGB-290 as commercialized will be used to treat cancer patients limited to having BRCA1 or BRCA2 mutation either in a monotherapy or a combination therapy. If BGB-290 is approved for sale in the United States for patients whose cancers have a BRCA1 or BRCA2 mutation, and if the validity of the relevant claims of these U.S. patents is upheld upon a validity challenge, then we would need a license in order to commercialize BGB-290 prior to expiration of these U.S. patents. In addition, we are also aware of corresponding issued patents in Europe and China. Depending upon circumstances, we may


need a license for jurisdictions outside the United States where we wish to commercialize BGB-290 before the expiration of a corresponding patent covering BGB-290. However, such a license may not be available on commercially reasonable terms or at all, which could materially and adversely affect our business.

Even if litigation or other proceedings are resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses, and could distract our technical personnel, management personnel, or both from their normal responsibilities. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments, and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the market price of the ordinary shares and/or ADSs. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available for development activities or any future sales, marketing or distribution activities. We may not have sufficient financial or other resources to adequately conduct such litigation or proceedings. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace.


Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment, and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for noncompliance with these requirements.

Periodic maintenance fees on any issued patent are due to be paid to the USPTO and other patent agencies in several stages over the lifetime of the patent. The USPTO and various non-U.S. governmental patent agencies require compliance with a number of procedural, documentary, fee payment, and other similar provisions during the patent application process. Although an inadvertent lapse can in many cases be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. Noncompliance events that could result in abandonment or lapse of a patent or patent application include failure to respond to official actions within prescribed time limits, non-payment of fees, and failure to properly legalize and submit formal documents. In any such event, our competitors might be able to enter the market, which would have a material adverse effect on our business.

The terms of our patents may not be sufficient to effectively protect our drug candidates and business.

        In most countries in which we file, including the United States, the term of an issued patent is generally 20 years from the earliest claimed filing date of a non-provisional patent application in the applicable country. Although various extensions may be available, the life of a patent and the protection it affords, is limited. Even if patents covering our drug candidates are obtained, we may be open to competition from other companies as well as generic medications once the patent life has expired for a drug. If patents are issued on our currently pending patent applications, the resulting patents will be expected to expire on dates ranging from 2031 to 2035, excluding any potential patent term extension or adjustment. Upon the expiration of our issued patent or patents that may issue from our pending patent applications, we will not be able to assert such patent rights against potential competitors and our business and results of operations may be adversely affected.

If we do not obtain additional protection under the Hatch-Waxman Amendmentspatent term extension and similar legislation in other countries extending the terms of our patents, if issued, relating to ourregulatory exclusivity for any drugs or drug candidates we may develop, our business may be materially harmed.

Depending upon the timing, duration and specifics of any FDA regulatorymarketing approval for ourof any drugs or drug candidates we may develop, one or more of our U.S. patents if issued, may be eligible for limited patent term


restoration extension under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent extension term extension of up to five years as compensation for patent term lost during drug developmentclinical trials and the FDA regulatory review process. PatentA patent term extensions, however,extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of drug approval, by the FDA, and only one patent canmay be extended and only those claims covering the approved drug, a method for using it, or a particular drug.

        The applicationmethod for patent term extension is subject to approval by the USPTO, in conjunction with the FDA. Wemanufacturing it may be extended. However, we may not be granted an extension because of, for example, failing to exercise due diligence during the testing phase or regulatory review process, failing to apply within applicable deadlines, failing to apply prior to expiration of relevant patents, or otherwise failing to satisfy applicable requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less than we request. In addition, no patent term extension system has been established in the PRC yet, and implementation of the patent term extension proposed in the Innovation Opinion and the Trade Agreement may not occur quickly. As a result, the patents we have in the PRC are not yet eligible to be extended for patent term lost during clinical trials and the regulatory review process. If we are unable to obtain a patent term extension for a given patent or the term of any such extension is less than we request, the period during which we will have the right to exclusively market our drug will be shortened and our competitors may obtain earlier approval of competing drugs,products following our patent expiration, and our ability to generate revenuesbusiness, financial condition, results of operations, and prospects could be materially adversely affected.

harmed.

Changes in patent law could diminish the value of patents in general, thereby impairing our ability to protect our drugs or drug candidates.

        As is the case with other biopharmaceutical companies, our success is heavily dependent on intellectual property, particularly patent rights. Obtaining and enforcing patents in the biopharmaceutical industry involves both technological and legal complexity, and is therefore costly, time-consuming, and inherently uncertain. In addition, the

The United States has recently enacted and is currently implementing wide-ranging patent reform legislation. Recent U.S. Supreme Court rulings have narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents once obtained, if any. Depending on decisions by the U.S. Congress, the federal courts and the USPTO, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future. For example, in a recent case,Assoc. for Molecular Pathology v. Myriad Genetics, Inc., the U.S. Supreme Court held that certain claims to naturally-occurring substances are not patentable. Although we do not believe that our currently-issued patent and any patents that may issue from our pending patent applications directed to our drug candidates if issued in their currently pending forms, as well as patent rights licensed by us, will be found invalid based on this decision, we cannot predict how future decisions by the courts, the U.S. Congress or the USPTO may impact the value of our patent rights. There could be similar changes in the laws of foreign jurisdictions that may impact the value of our patent rights or our other intellectual property rights.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed. We may be subject to claims that our employees have wrongfully used or disclosed alleged trade secrets of their former employers.

In addition to our issued patent and pending patent applications, we rely on trade secrets, including unpatented know-how, technology and other proprietary information, to maintain our competitive position and to protect our drugs and drug candidates. We seek to protect these trade secrets, in part, by entering into non-disclosure and confidentiality agreements with parties that have access to them, such as our employees, corporate collaborators, outside scientific collaborators, sponsored researchers, contract manufacturers, consultants, advisors and other third parties. We also enter into confidentiality and invention or patent assignment agreements with our employees and consultants. However, any of these parties may breach such agreements and disclose our proprietary information, and we may not be


able to obtain adequate remedies for such breaches. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret can be difficult, expensive and time-consuming, and the outcome is unpredictable. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent them from using that technology or information to compete with us and our competitive position would be harmed.


Furthermore, many of our employees, including our senior management, were previously employed at other biotechnology or pharmaceutical companies, including our competitors or potential competitors. Some of these employees, including each member of our senior management, executed proprietary rights, non-disclosure and non-competition agreements in connection with such previous employment. Although we try to ensure that our employees do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or these employees have used or disclosed intellectual property, including trade secrets or other proprietary information, of any such employee'semployee’s former employer. We are not aware of any threatened or pending claims related to these matters or concerning the agreements with our senior management, but in the future litigation may be necessary to defend against such claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management.

In addition, while we typically require our employees, consultants and contractors who may be involved in the development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who in fact develops intellectual property that we regard as our own, which may result in claims by or against us related to the ownership of such intellectual property. If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights. Even if we are successful in prosecuting or defending against such claims, litigation could result in substantial costs and be a distraction to our management and scientific personnel.

We may not be successful in obtaining or maintaining necessary rights for our development pipeline through acquisitions and in-licenses.

Because our programs may involve additional drug candidates that may require the use of proprietary rights held by third parties, the growth of our business may depend in part on our ability to acquire and maintain licenses or other rights to use these proprietary rights. We may be unable to acquire or in-license any compositions, methods of use, or other third-party intellectual property rights from third parties that we identify. The licensing and acquisition of third-party intellectual property rights is a competitive area, and a number of more established companies are also pursuing strategies to license or acquire third-party intellectual property rights that we may consider attractive. These established companies may have a competitive advantage over us due to their size, cash resources and greater clinical development and commercialization capabilities.

        In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us. We also may be unable to license or acquire third-party intellectual property rights on terms that would allow us to make an appropriate return on our investment. If we are unable to successfully obtain rights to required third-party intellectual property rights, our business, financial condition and prospects for growth could suffer.


If we fail to comply with our obligations in the agreements under which we license intellectual property rights from third parties or otherwise experience disruptions to our business relationships with our licensors, we could be required to pay monetary damages or could lose license rights that are important to our business.

We have entered into license agreements with third parties providing us with rights under various third-party patents and patent applications, including the rights to prosecute patent applications and to enforce patents. Certain of theseapplications. These license agreements impose and, for a variety of purposes, we may enter into additional licensing and funding arrangements with third parties that also may impose diligence, development or commercialization timelines and milestone payment, royalty, insurance and other obligations on us. Under certain of our existing licensing agreements, we are obligated to pay royalties on net product sales of our drug candidates once commercialized, pay a percentage of sublicensing revenues, make other specified payments relating to our drug candidates or pay license maintenance and other fees. We also have diligence and clinical development obligations under certain of these agreements that we are required to satisfy. If we fail to comply with our obligations under our current or future license agreements, our counterparties may have the right to terminate these agreements, in which event we might not be able to develop, manufacture or market any drug or drug candidate that is covered by the licenses provided for under these agreements or we may face claims for monetary damages or other penalties under these agreements. Such an occurrence could diminish the value of these products and our company. Termination of the licenses provided for under these agreements or reduction or elimination of our rights under these agreements may result in our having to negotiate new or reinstated agreements with less favorable terms, or cause us to lose our rights under these agreements, including our rights to important intellectual property or technology.

Risks Related to Our Reliance on Third Parties

If we fail to maintain an effective distribution channel for our drugs, our business and sales of the relevant drugs could be adversely affected.
We rely on third partiesthird-party distributors to conductdistribute our preclinical studiesapproved drugs. For example, we rely on a sole third-party distributor to distribute BMS’s approved cancer therapies, ABRAXANE, REVLIMID, and clinical trials. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may notVIDAZA, and multiple third-party distributors for the distribution of BRUKINSA and tislelizumab. We also expect to rely on third-party distributors to distribute our other internally developed drug products, if approved, and the oncology products of Amgen to be ablecommercialized by us in China under the collaboration with Amgen. Our ability to obtain regulatory approval for or commercialize our drug candidatesmaintain and grow our business could be substantially harmed.

        We have relied upon and planwill depend on our ability to continue to rely upon third-party CROs to monitor and manage data for our ongoing preclinical and clinical programs. We rely on these parties for execution of our preclinical studies and clinical trials, and control only certain aspects of their activities. Nevertheless, we are responsible for ensuringmaintain an effective distribution channel that each of our studies is conducted in accordance withensures the applicable protocol, legal and regulatory requirements and scientific standards, and our reliance on the CROs does not relieve us of our regulatory responsibilities. We and our CROs and our clinical investigators are required to comply with GCPs, which are regulations and guidelines enforced by the FDA, CFDA, EMA and other comparable regulatory authorities for alltimely delivery of our drugs to the relevant markets where we generate market demand through our sales and marketing activities. However, we have relatively limited control over our distributors, who may fail to distribute our drugs in clinical development. Regulatory authorities enforce these GCPsthe manner we contemplate. For example, while we have long-standing business relationship with our sole distributor for the in-licensed products from BMS, the agreement we entered into with our sole distributor can be terminated by both parties upon six months’ written notice. If price controls or other factors substantially reduce the margins


our distributors can obtain through periodic inspections of trial sponsors, principal investigators and trial sites. If we or anythe resale of our CROs or clinical investigators failproducts to comply with applicable GCPs, the clinical data generated in our clinical trialshospitals, medical institutions and sub-distributors, they may be deemed unreliable and the FDA, CFDA, EMA or comparable regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. We cannot assure you that upon inspection by a given regulatory authority, such regulatory authority will determine that any of our clinical trials comply with GCP regulations. In addition, our clinical trials must be conducted with product produced under cGMP regulations. Our failure to comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process.

        Our CROs have the right to terminate their agreementsrelationship with us in the event of an uncured material breach. In addition, some of our CROs have an ability to terminate their respective agreements with us if it can be reasonably demonstrated that the safety of the subjects participating in our clinical trials warrants such termination, ifus. While we make a general assignment for the benefit of our creditors or if webelieve alternative distributors are liquidated.


        If any of our relationships with these third-party CROs terminate, we may not be able to enter into arrangements with alternative CROs or to do so on commercially reasonable terms. In addition, our CROs are not our employees, and except for remediesreadily available, to us under our agreements with such CROs, we cannot control whether or not they devote sufficient time and resources to our ongoing clinical, nonclinical and preclinical programs. If CROs do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols, regulatory requirements or for other reasons, our clinical trials may be extended, delayed or terminated and we may not be able to obtain regulatory approval for or successfully commercialize our drug candidates. As a result, our results of operations and the commercial prospects for our drug candidates would be harmed, our costs could increase and our ability to generate revenues could be delayed.

        Switching or adding additional CROs involves additional cost and requires management time and focus. In addition, there is a natural transition period when a new CRO commences work. As a result, delays occur, which can materially influencerisk that, if the distribution of our ability to meetdrugs is interrupted, our desired clinical development timelines. Though we carefully manage our relationships with our CROs, there cansales volumes and business prospects could be no assurance that we will not encounter similar challenges or delays in the future or that these delays or challenges will not have a material adverse effect on our business, financial condition and prospects.

adversely affected.

We expect to rely on third parties to manufacture at least a portion of our commercial and clinical drug candidate supplies, and we intend to rely on third parties for at least a portion of the manufacturing process of our drug candidates, if approved.supplies. Our business could be harmed if those third parties fail to provide us with sufficient quantities of product or fail to do so at acceptable quality levels or prices.

Although we currently have a facilitymanufacturing facilities that may be used as ourfor clinical-scale manufacturing and processing and are building a biologics manufacturing facility in China, we intend to at least partially rely on outside vendors to manufacture supplies and process our drugs and drug candidates. For example, we have entered into a commercial supply agreement for tislelizumab with Boehringer Ingelheim Biopharmaceuticals (China) Ltd. ("Boehringer Ingelheim") and entered into a commercial supply agreement for BRUKINSA with Catalent Pharma Solutions, LLC ("Catalent"). In addition, we rely on BMS and its third-party manufacturers for supply of ABRAXANE, REVLIMID, and VIDAZA in China. We will be dependent on Amgen for the supply of the drugs that we plan to develop and commercialize in China under the collaboration with Amgen. We have not yet causedlimited experience in manufacturing or processing our drugs and drug candidates to be manufactured or processed on a commercial scale, including BRUKINSA and may not be able to do so for any of our drug candidates. Wetislelizumab. Additionally, we have limited experience in managing the manufacturing process, and our process may be more difficult or expensive than the approaches currently in use.

Although we intend to further develop our own manufacturing facilities, we also intend to use third parties as part of our manufacturing process.process and for the clinical and commercial supply of our drugs and drug candidates. Our anticipated reliance on a limited number of third-party manufacturers exposes us to the following risks:

we may be unable to identify manufacturers on acceptable terms or at all because the number of potential manufacturers is limited and the FDA, CFDA,NMPA, EMA or other comparable regulatory authorities must evaluate and/or approve any manufacturers as part of their regulatory oversight of our drugs and drug candidates. This approvalevaluation would require new testing and cGMP-complianceGMP-compliance inspections by FDA, CFDA,NMPA, EMA or other comparable regulatory authorities. In addition, a new manufacturer would have to be educated in, or develop substantially equivalent processes for, production of our drugs;

authorities;
our manufacturers may have little or no experience with manufacturing our drugs and drug candidates, and therefore may require a significant amount of support from us in order to implement and maintain the infrastructure and processes required to manufacture our drugs and drug candidates;

our third-party manufacturers might be unable to timely manufacture our drugs and drug candidates or produce the quantity and quality required to meet our clinical and commercial needs, if any;

contract manufacturersany. For example, we encountered supply disruptions of ABRAXANE in 2019, which may not be able to execute our manufacturing procedures and other logistical support requirements appropriately;

manufacturers are subject to ongoing periodic unannounced inspection by the FDA and corresponding state agencies in the United States to ensure strict compliance with cGMPsGMPs and other government regulations and by other comparable regulatory authorities for corresponding non-U.S. requirements. We do not have control over third-party manufacturers'manufacturers’ compliance with these regulations and requirements;

we may not own, or may have to share, the intellectual property rights to any improvements made by our third-party manufacturers in the manufacturing process for our drugs;

our third-party manufacturers could breach or terminate their agreement with us;

drugs and drug candidates;
raw materials and components used in the manufacturing process, particularly those for which we have no other source or supplier, may not be available or may not be suitable or acceptable for use due to material or component defects;

and
our contract manufacturers and critical reagentdrug component suppliers may be subject to disruptions in their business, including unexpected demand for or shortage of raw materials or components, cyber-attacks on supplier systems, labor disputes or shortage and inclement weather, as well as natural or man-made disasters; and

our contract manufacturers may have unacceptable or inconsistent product quality success rates and yields.

disasters.

Each of these risks could delay or prevent the completion of our clinical trials or the approval of any of our drug candidates, by the FDA, CFDA, EMA or other comparable regulatory authorities, result in higher costs or adversely impact development or commercialization of our drug candidates.drugs. In addition, we will rely on third parties to perform certain specification tests on our drugs and drug candidates prior to delivery to patients. If these tests are not appropriately done and test data are not reliable, patients could be put at risk of serious harm and the FDA, CFDA, EMA or other comparable regulatory authorities could place significant restrictions on our company until deficiencies are remedied.

        The manufacture of drug and biological products is complex and requires significant expertise and capital investment, including

Currently, the development of advanced manufacturing techniques and process controls.

        Currently, our drug raw materials for our manufacturing activities are supplied by multiple source suppliers, although portions of our supply chain may rely on sole source suppliers. We have agreements for the supply of drug materials with manufacturers or suppliers that we believe have sufficient capacity to meet our demands. In addition, we believe that adequate alternative sources


for such supplies exist. However, there is a risk that, if supplies are interrupted, it would materially harm our business.

For example, the COVID-19 outbreak could have a broad impact on the production and supplies of active ingredients or other raw materials and result in a potential shortage of supply, as a large portion of such active ingredients or raw materials used by drug manufacturers worldwide are from China. Therefore, drug manufacturers including us could be negatively impacted.

Manufacturers of drug and biological products often encounter difficulties in production, particularly in scaling up or out, validating the production process, and assuring high reliability of the manufacturing process (including the absence of contamination). These problems include logistics and shipping, difficulties with production costs and yields, quality control, including stability of the product, product testing, operator error, availability of qualified personnel, as well as compliance with strictly enforced federal, state and non-U.S. regulations. Furthermore, if contaminants are discovered in ourthe supply of our drugs and drug candidates or in the manufacturing facilities, such manufacturing facilities may need to be closed for an extended period of time to investigate and remedy the contamination. We cannot assure you that any stability failures or other issues relating to the manufacture of our drugs and drug candidates will not occur in the future. Additionally, our manufacturers may experience manufacturing difficulties due to resource constraints or as a result of labor disputes or unstable political environments. If our manufacturers were to encounter any of these difficulties, or otherwise fail to comply with their contractual obligations, our ability to provide our drugs for commercial sale and our drug candidatecandidates to patients in clinical trials would be


jeopardized. Any delay or interruption in the supply of clinical trial supplies could delay the completion of clinical trials, increase the costs associated with maintaining clinical trial programs and, depending upon the period of delay, require us to begin new clinical trials at additional expense or terminate clinical trials completely.

If third-party manufacturers fail to comply with manufacturing regulations, our financial results and financial condition will be adversely affected.

Before a third party can begin commercial manufacture of our drugs and drug candidates, and potential drugs, contract manufacturers are subject to regulatory inspections of their manufacturing facilities, processes and quality systems. Due to the complexity of the processes used to manufacture drug and biological products and our drug candidates, any potential third-party manufacturer may be unable to initially pass federal, state or international regulatory inspections in a cost effectivecost-effective manner in order for us to obtain regulatory approval of our drug candidates. If our contract manufacturers do not pass their inspections by the FDA, CFDA, EMA or other comparablerelevant regulatory authorities, our commercial supply of drug product or substance will be significantly delayed and may result in significant additional costs, including the delay or denial of any marketing application for our drug candidates.candidates or disruption in sales. In addition, drug and biological manufacturing facilities are continuously subject to inspection by the FDA, CFDA, EMA and other comparable regulatory authorities, before and after drug approval, and must comply with cGMPs.GMPs. Our contract manufacturers may encounter difficulties in achieving quality control and quality assurance and may experience shortages in qualified personnel. In addition, contract manufacturers'manufacturers’ failure to achieve and maintain high manufacturing standards in accordance with applicable regulatory requirements, or the incidence of manufacturing errors, could result in patient injury, product liability claims, product shortages, product recalls or withdrawals, delays or failures in product testing or delivery, cost overruns or other problems that could seriously harm our business. If a third-party manufacturer with whom we contract is unable to comply with manufacturing regulations, we may also be subject to fines, unanticipated compliance expenses, recall or seizure of our drugs, product liability claims, total or partial suspension of production and/or enforcement actions, including injunctions, and criminal or civil prosecution. These possible sanctions could materially adversely affect our financial results and financial condition.

Furthermore, changes in the manufacturing process or procedure, including a change in the location where the product is manufactured or a change of a third-party manufacturer, could require prior review by the FDA, CFDA, EMA or other comparable regulatory authorities and/or approval of the manufacturing process and procedures in accordance with the FDA, CFDA or EMA's regulations, or comparableapplicable requirements. This review may be costly and time consuming and could delay or prevent the launch of a product.product or impact commercialization or continuous supply of approved drugs. The new facility will also be subject to pre-approval inspection. In addition, we have to demonstrate that the product made at the new facility is equivalent to the product made at the former facility by physical and chemical methods, which are costly and time consuming. It is also possible that the FDA, CFDA, EMA or other comparable regulatory authorities may require clinical testing as a way to prove equivalency, which would result in additional costs and delay.

We rely on third parties to conduct our preclinical studies and clinical trials and we must work effectively with collaborators to develop our drug candidates. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our drugs and drug candidates and our business could be substantially harmed.
We have relied upon and plan to continue to rely upon third-party CROs to monitor and manage data for our ongoing preclinical and clinical programs. We rely on these parties for execution of our preclinical studies and clinical trials, and control only certain aspects of their activities. Nevertheless, we are responsible for ensuring that each of our studies is conducted in accordance with the applicable protocol, legal and regulatory requirements and scientific standards, and our reliance on the

CROs does not relieve us of our regulatory responsibilities. We, our CROs for our clinical programs and our clinical investigators are required to comply with GCPs, which are regulations and guidelines enforced by the FDA, NMPA, EMA and other comparable regulatory authorities for all of our drugs in clinical development. If we or any of our CROs or clinical investigators fail to comply with applicable GCPs and other regulatory requirements, the clinical data generated in our clinical trials may be deemed unreliable and the FDA, NMPA, EMA or comparable regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. In addition, our pivotal clinical trials must be conducted with product produced under GMP regulations. Our failure to comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process. We could also be subject to government investigation and enforcement actions.
If any of our relationships with these third-party CROs terminate, we may not be able to enter into arrangements with alternative CROs or to do so on commercially reasonable terms. In addition, our CROs are not our employees, and except for remedies available to us under our agreements with such CROs, we cannot control whether or not they devote sufficient time and resources to our ongoing clinical and nonclinical programs. If CROs do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the clinical data they or our clinical investigators obtain is compromised due to the failure to adhere to our clinical protocols, regulatory requirements or for other reasons, our clinical trials may be extended, delayed or terminated and we may not be able to obtain regulatory approval for or successfully commercialize our drug candidates. As a result, our results of operations and the commercial prospects for our drug candidates would be harmed, our costs could increase and our ability to generate revenues could be delayed.
Switching or adding additional CROs involves additional cost and delays, which can materially influence our ability to meet our desired clinical development timelines. There can be no assurance that we will not encounter similar challenges or delays in the future or that these delays or challenges will not have a material adverse effect on our business, financial condition and prospects.
Our future revenues are dependent on, among other factors, our ability to identify a collaboration partner and negotiate acceptable terms for a collaboration agreement and to work effectively with collaborators to develop our drugs and drug candidates, including to obtain regulatory approval. Our arrangements with collaborators will be critical to successfully bringing products to market and commercializing them. We rely on collaborators in various respects, including to undertake research and development programs and conduct clinical trials, manage or assist with the regulatory filings and approval process and to assist with our commercialization efforts. We do not control our collaborators; therefore, we cannot ensure that these third parties will adequately and timely perform all of their obligations to us. If they fail to complete the remaining studies successfully, or at all, it could delay, adversely affect or prevent regulatory approval. We cannot guarantee the satisfactory performance of any of our collaborators and if any of our collaborators breach or terminate their agreements with us, we may not be able to successfully commercialize the licensed product which could materially and adversely affect our business, financial condition, cash flows and results of operations.
We have entered into collaborations and may form or seek collaborations or strategic alliances or enter into additional licensing arrangements in the future, and we may not realize the benefits of such collaborations, alliances or licensing arrangements.

We may form or seek strategic alliances, create joint ventures or collaborations, or enter into additional licensing arrangements with third parties that we believe will complement or augment our research, development and commercialization efforts with respect to our drugs and drug candidates and any future drugs and drug candidates that we may develop. Any of these relationships may require us to incur non-recurring and other charges, increase our near and long-term expenditures, issue securities that dilute our existing shareholders, or disrupt our management and business.
In August 2017, we acquired Celgene Corporation's commercial operations in China and an exclusive license to Celgene's (now BMS’s) commercial cancer portfolio in China, ABRAXANE, REVLIMID, and VIDAZA (the “BMS China License”). On October 31, 2019, we entered into a strategic collaboration with Amgen with respect to its commercial-stage oncology products XGEVA, KYPROLIS and BLINCYTO and 20 clinical- and late-preclinical-stage oncology pipeline products. We are authorized to commercialize the three oncology products in China for five or seven years and have the option to retain one of the three oncology products to commercialize for as long as the product is sold in China. For each pipeline product that is approved in China, we have the right to commercialize the pipeline product for seven years in China and the right to retain approximately one of every three approved pipeline assets, up to a total of six, other than AMG 510, for commercialization in China.
Our strategic collaborations with Amgen and BMS involve numerous risks. For our collaboration with Amgen, we cannot be certain that we will achieve the financial and other benefits that led us to enter into the collaboration. Moreover, we may not

achieve the revenue and cost synergies expected from our collaborations with Amgen or BMS for their commercial products in China, and our management’s attention may be diverted from our drug discovery and development business. These synergies are inherently uncertain, and are subject to significant business, economic and competitive uncertainties and contingencies, many of which are difficult to predict and are beyond our control. If we achieve the expected benefits, they may not be achieved within the anticipated time frame. Lastly, strategic collaborations can be terminated for various reasons. For example, in 2013,our strategic collaboration with Celgene for the development and commercialization of tislelizumab, which we entered into


in connection with the BMS China License in 2017, was terminated in June 2019 in advance of the acquisition of Celgene by BMS, and we received a $150 million payment and regained global rights to tislelizumab. The termination of the collaboration agreementsagreement for tislelizumab did not impact the BMS China License, which remains in effect.

Additionally, from time to time, we may enter into joint ventures with Merck KGaA, Darmstadt Germany pursuantother companies. Establishment of a joint venture involves significant risks and uncertainties, including (i) our ability to cooperate with our strategic partner, (ii) our strategic partner having economic, business, or legal interests or goals that are inconsistent with ours, and (iii) the potential that our strategic partner may be unable to meet its economic or other obligations, which we have agreedmay require us to license the ex-China rights of BGB-283 to Merck KGaA, Darmstadt Germany as discussed further in the section titled "Item 1—Business—Collaboration with Merck KGaA, Darmstadt Germany" in this Annual Report. In addition, wefulfill those obligations alone.
We face significant competition in seeking appropriate strategic partners and the negotiation process is time-consuming and complex. Moreover, we may not be successful in our efforts to establish a strategic partnership or other alternative arrangements for our drugs and drug candidates because they may be deemed to be at too early of a stage of development for collaborative effort and third parties may not view our drugs and drug candidates as having the requisite potential to demonstrate safety and efficacy.efficacy or commercial viability. If and when we collaborate with a third party for development and commercialization of a drug or drug candidate, we can expect to relinquish some or all of the control over the future success of that drug or drug candidate to the third party.

For any drugs or drug candidates that we may seek to in-license from third parties, we may face significant competition from other pharmaceutical or biotechnology companies with greater resources or capabilities than us, and any agreement that we do enter may result in the anticipated benefits.

Further, collaborations involving our drugs and drug candidates are subject to numerous risks, which may include the following:

collaborators have significant discretion in determining the efforts and resources that they will apply to a collaboration;

collaborators may not pursue development and commercialization of our drugs and drug candidates or may elect not to continue or renew development or commercialization programs based on clinical trial results, changes in their strategic focus due to the acquisition of competitive drugs, availability of funding, or other external factors, such as a business combination that diverts resources or creates competing priorities;

collaborators may delay clinical trials, provide insufficient funding for a clinical trial, stop a clinical trial, abandon a drug candidate, repeat or conduct new clinical trials, or require a new formulation of a drug candidate for clinical testing;

collaborators could independently develop, or develop with third parties, drugs that compete directly or indirectly with our drugs or drug candidates;

a collaborator with marketing and distribution rights to one or more drugs may not commit sufficient resources to their marketing and distribution;

collaborators may not properly maintain or defend our intellectual property rights or may use our intellectual property or proprietary information in a way that gives rise to actual or threatened litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us to potential liability;

disputes may arise between us and a collaborator that cause the delay or termination of the research, development or commercialization of our drugs and drug candidates, or that result in costly litigation or arbitration that diverts management attention and resources;

collaborations may be terminated and, if terminated, may result in a need for additional capital to pursue further development or commercialization of the applicable drugs and drug candidates; and

collaborators may own or co-own intellectual property covering our drugs that results from our collaborating with them, and in such cases, we would not have the exclusive right to commercialize such intellectual property.


As a result, if we enter into collaboration agreements and strategic partnerships or license our drugs, we may not be able to realize the benefit of such transactionscurrent or future collaborations, strategic partnerships or the license of our third-party drugs and drug candidates if we are unable to successfully integrate themsuch products with our existing operations and company culture, which could delay our timelines or otherwise adversely affect our business. We also cannot be certain that, following a strategic transaction or license, we will achieve the revenue or specific net income that justifies such transaction. If we are unable to reach agreements with suitable collaborators on a timely basis, on acceptable terms, or at all,


we may have to curtail the development of a drug candidate, reduce or delay its development program or one or more of our other development programs, delay its potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to fund and undertake development or commercialization activities on our own, we may need to obtain additional expertise and additional capital, which may not be available to us on acceptable terms or at all. If we fail to enter into collaborations and do not have sufficient funds or expertise to undertake the necessary development and commercialization activities, we may not be able to further develop our drugs and drug candidates or bring them to market and generate product sales revenue, which would harm our business prospects, financial condition and results of operations.

Risks Related to Our Industry, Business and Operations

Our future success depends on our ability to retain the Chairman of our scientific advisory board and our Chief Executive Officer and other key executives and to attract, retain and motivate qualified personnel.

We are highly dependent on Xiaodong Wang, Ph.D., our Founder,Co-Founder, Chairman of our scientific advisory board, which may from time to time provide us assistance upon our request, and director; John V. Oyler, our Founder,Co-Founder, Chief Executive Officer and Chairman of the board;board of directors; and the other principal members of our management and scientific teams and scientific advisory board.teams. Although we have formal employment agreements or offer letters with each of our executive officers, except for our Chief Executive Officer, these agreements do not prevent our executives from terminating their employment with us at any time. We do not maintain "key person"“key person” insurance for any of our executives or other employees. The loss of the services of any of these persons could impede the achievement of our research, development and commercialization objectives.

To induce valuable employees to remain at our company, in addition to salary and cash incentives, we have provided share option, restricted share unit and restricted share grants that vest over time. The value to employees of these equity grants that vest over time may be significantly affected by movements in the ADS and/or ordinary share price that are beyond our control and may at any time be insufficient to counteract more lucrative offers from other companies. Although we have employment agreements or offer letters with our key employees, any of our employees could leave our employment at any time, with or without notice.

Recruiting and retaining qualified scientific, clinical, manufacturing and sales and marketing personnel or consultants will also be critical to our success. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating and executing our discovery, and preclinicalclinical development, manufacturing and commercialization strategy. The loss of the services of our executive officers or other key employees and consultants could impede the achievement of our research, development, manufacturing and commercialization objectives and seriously harm our ability to successfully implement our business strategy.

Furthermore, replacing executive officers, and key employees or consultants may be difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to successfully develop, gain regulatory approval of and commercialize products. Competition to hire from this limited pool is intense, and we may be unable to hire, train, retain or motivate these key personnel or consultants on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies for similar personnel.

We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. Our consultants and advisors may be employed by employers other than us and may have commitments under consulting or advisory contracts with other entities that may limit their availability to us. If we are unable to continue to attract and retain high quality personnel, our ability to pursue our growth strategy will be limited.


We will need to increasehave significantly increased the size and capabilities of our organization, and we may experience difficulties in managing our growth.

        As

At the beginning of December 31, 2016,2019, we had 3482,070 employees, and consultants and mostwe ended the year with 3,359 employees, an increase of approximately 62%. Most of our employees are full-time. As our research, development, manufacturing and commercialization plans and strategies develop, and as we transition into operating as a public company,evolve, we must add a significant number of additional managerial, operational, manufacturing, sales, marketing, financial and other personnel. FutureOur recent growth and any future growth will impose significant added responsibilities on members of management, including:

identifying, recruiting, integrating, maintaining, and motivating additional employees;


managing our internal development efforts effectively, including the clinical and FDA or other comparable regulatory authority review process for our drug candidates, while complying with our contractual obligations to contractors and other third parties; and

improving our operational, financial and management controls, reporting systems and procedures.

Our future financial performance and our ability to develop and commercialize our drugs and drug candidates will depend, in part, on our ability to effectively manage our recent growth and any future growth, and our management may also have to divert a disproportionate amount of its attention away from day-to-day activities in order to devote a substantial amount of time to managing these growth activities.

We currently rely, and for the foreseeable future will continue to rely, in substantial part on certain independent organizations, advisors and consultants to provide certain services. There can be no assurance that the services of these independent organizations, advisors and consultants will continue to be available to us on a timely basis when needed, or that we can find qualified replacements. In addition, if we are unable to effectively manage our outsourced activities or if the quality or accuracy of the services provided by consultants is compromised for any reason, our clinical trials may be extended, delayed or terminated, and we may not be able to obtain regulatory approval of our drug candidates or otherwise advance our business. There can be no assurance that we will be able to manage our existing consultants or find other competent outside contractors and consultants on economically reasonable terms, if at all.

If we are not able to effectively manage our growth and further expand our organization by hiring new employees and expanding our groups of consultants and contractors as needed, we may not be able to successfully implement the tasks necessary to further develop, manufacture and commercialize our drugs and drug candidates and, accordingly, may not achieve our research, development, manufacturing and commercialization goals.

Our employees, independent contractors, consultants, commercial partners and vendors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.

We are exposed to the riskincur significant costs as a result of fraud, misconduct or other illegal activity by our employees, independent contractors, consultants, commercial partners and vendors. Misconduct by these parties could include intentional, reckless and negligent conduct that fails to: comply with the laws of the FDA and other similar non-U.S. regulatory authorities; provide true, complete and accurate information to the FDA and other similar non-U.S. regulatory authorities; comply with manufacturing standards we have established; comply with healthcare fraud and abuse lawsoperating as a public company in the United States and similar non-U.S. fraudulent misconduct laws; or reportHong Kong, and our management is required to devote substantial time to compliance requirements, including establishing and maintaining internal controls over financial information or data accurately orreporting. We may be exposed to disclose unauthorized activitiespotential risks if we are unable to us. If we obtain FDA approval of any of our drug candidates and begin commercializing those drugscomply with these requirements.
As a public company in the United States our potential exposure under U.S. laws will increase significantly and our costs associated with compliance with such laws are also likely to increase. These laws may impact, among other things, our current activities with principal investigators and research patients, as well as future sales, marketing and education programs. In particular, the promotion, sales and marketing of healthcare items and services, as well as certain business arrangements in the


healthcare industry, are subject to extensive laws designed to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, structuring and commission(s), certain customer incentive programs and other business arrangements generally. Activities subject to these laws also involve the improper use of information obtained in the course of patient recruitment for clinical trials, which could result in regulatory sanctions and cause serious harm to our reputation. It is not always possible to identify and deter misconduct by employees and other parties, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant fines or other sanctions.

Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.

        As a public company,Hong Kong, we are subject to the periodic reporting requirements of the Securities Exchange Act.Act of 1934, as amended (the "Exchange Act"), and the listing rules of the Nasdaq Stock Market ("Nasdaq"), and The Stock Exchange of Hong Kong Limited (the "HKEx"), and incur significant legal, accounting and other expenses under the Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley Act"), together with rules implemented by the U.S. Securities and Exchange Commission, or SEC, and applicable market regulators, and the listing rules of the Nasdaq and HKEx. These rules impose various requirements on public companies, including requiring certain corporate governance practices. Our management and other personnel devote a substantial amount of time to these requirements. Moreover, these rules and regulations increase our legal and financial compliance costs and make some activities more time-consuming and costly.

For example, the Sarbanes-Oxley Act requires, among other things, that we maintain effective internal controls for financial reporting and disclosure controls and proceduresprocedures. In particular, we must perform system and process evaluations and testing of our internal controls over financial reporting to allow management to report on the effectiveness of our internal controls over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act. We have limited experience in complying with Section 404, and such compliance may require that we incur substantial accounting expenses and expend significant management efforts. Our testing may reveal deficiencies in our internal controls over financial reporting that are designed to reasonably assure that information requireddeemed to be disclosed by usmaterial weaknesses. In the event we identify significant deficiencies or material weaknesses in reportsour internal controls that we file cannot remediate in a timely manner, the market price of our ordinary shares and/or submit under the Exchange Act is accumulatedADSs could decline if investors and communicated to management, and recorded, processed, summarized and reported within the time periods specifiedothers lose confidence in the rules and formsreliability of the SEC. We believe that any disclosure controls and proceduresour financial statements, we could be subject to sanctions or internal controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.

        These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumventedinvestigations by the individual acts of some persons, by collusion of twoSEC, HKEx or more people or by an unauthorized override of the controls. Accordingly, because of the inherent limitations inother applicable regulatory authorities and our control system, misstatements due to error or fraud may occur and notbusiness could be detected.

In order to satisfy our obligations as a public company, we will need to hire additional qualified accounting and financial personnel with appropriate public company experience.

        As a newly public company, we need to establish and maintain effective disclosure and financial controls and make changes in our corporate governance practices. We need to hire additional accounting and financial personnel with appropriate public company experience and technical accounting knowledge, and it may be difficult to recruit and maintain such personnel. Even if we are able to hire appropriate personnel, our existing operating expenses and operations will be impacted by the direct costs of their employment and the indirect consequences related to the diversion of management resources from product development efforts.

harmed.

If we engage in future acquisitions or strategic partnerships, this may increase our capital requirements, dilute our shareholders, cause us to incur debt or assume contingent liabilities, and subject us to other risks.

        We

From time to time, we may evaluate various acquisitions and strategic partnerships, including licensing or acquiring complementary products, intellectual property rights, technologies or businesses. Any completed, in-process or potential acquisition or strategic partnership may entail numerous risks, including:

increased operating expenses and cash requirements;

the assumption of additional indebtedness or contingent or unforeseen liabilities;

the issuance of our equity securities;

assimilation of operations, intellectual property and products of an acquired company, including difficulties associated with integrating new personnel;

In addition, if we undertake acquisitions, we may issue dilutive securities, assume or incur debt obligations, incur large one-time expenses and acquire intangible assets that could result in significant future amortization expense. For example, in connection with the Amgen transaction, we issued to Amgen a total of 206,635,013 ordinary shares in the form of ADSs, representing 20.5% of the issued share capital of the Company after giving effect to the share issuance, which resulted in Amgen becoming our largest shareholder and the ownership of our existing shareholders being diluted.
PRC regulations and rules concerning mergers and acquisitions, including the Regulations on Mergers and Acquisitions of Domestic Companies by Foreign Investors (the "M&A Rules"), and other recently adopted regulations and rules with respect to mergers and acquisitions established additional procedures and requirements that could make merger and acquisition activities by foreign investors more time consuming and complex. For example, the M&A Rules require that the Ministry of Commerce of the PRC (the "MOFCOM") be notified in advance of any change-of-control transaction in which a foreign investor takes control of a PRC domestic enterprise, if (i) any important industry is concerned, (ii) such transaction involves factors that have or may have impact on the national economic security, or (iii) such transaction will lead to a change in control of a domestic enterprise which holds a famous trademark or PRC time-honored brand. Moreover, according to the Anti-Monopoly Law of the PRC and the Provisions on Thresholds for Prior Notification of Concentrations of Undertakings (the "Prior Notification Rules") issued by the State Council, the concentration of business undertakings by way of mergers, acquisitions or contractual arrangements that allow one market player to take control of or to exert decisive impact on another market player must also be notified in advance to the State Administration of Market Regulation (the "SAMR") when the threshold is crossed and such concentration shall not be implemented without the clearance of prior notification. In addition, the Regulations on Implementation of Security Review System for the Merger and Acquisition of Domestic Enterprise by Foreign Investors (the "Security Review Rules") issued by the MOFCOM specify that mergers and acquisitions by foreign investors that raise “national defense and security” concerns and mergers and acquisitions through which foreign investors may acquire the de facto control over domestic enterprises that raise “national security” concerns are subject to strict review by the MOFCOM, and the rules prohibit any activities attempting to bypass a security review by structuring the transaction through, among other things, trusts, entrustment or contractual control arrangements.
We may also be subject to similar review and regulations in other jurisdictions, such as the laws and regulations on foreign investment in the United States under the jurisdiction of the Committee on Foreign Investment in the United States (the "CFIUS") and other agencies, including the Foreign Investment Risk Review Modernization Act (the "FIRRMA"), adopted in August 2018.
In the future, we may notgrow our business by acquiring complementary businesses. Complying with the requirements of the above-mentioned regulations and other relevant rules to complete such transactions could be able to locate suitable acquisition opportunitiestime consuming, and this inability could impairany required approval processes, including obtaining approval from CFIUS, the SAMR, the MOFCOM or its local counterparts may delay or inhibit our ability to growcomplete such transactions. It is unclear whether those complementary businesses we may acquire in the future would be deemed to be in an industry that raises “national defense and security” or obtain access“national security” concerns.
However, CFIUS, MOFCOM or other government agencies may publish explanations in the future determining that certain of the complementary business is in an industry subject to technology or products thatthe security review, in which case our future acquisitions in the United States and the PRC, including those by way of entering into contractual control arrangements with target entities, may be importantclosely scrutinized or prohibited. Our ability to the development ofexpand our business.

business or maintain or expand our market share through future acquisitions would as such be materially and adversely affected.

If we fail to comply with the U.S. Foreign Corrupt Practices Act or other anti-bribery and corruption laws, our reputation may be harmed and we could be subject to penalties and significant expenses that have a material adverse effect on our business, financial condition and results of operations.

        Although currently our primary operating business is in China, we

We are subject to the Foreign Corrupt Practices Act or FCPA.(the "FCPA"). The FCPA generally prohibits us from making improper payments to non-U.S. officials for the purpose of obtaining or retaining business. We are also subject to the anti-bribery and

corruption laws of other jurisdictions, particularly China. The anti-bribery laws in China generally prohibit companies and their intermediaries from making payments to government officials for the purpose of obtaining or retaining business or securing any other improper advantage. As our business has expanded, the applicability of the FCPA and other anti-bribery and corruption laws to our operations has increased.
We do not fully control the interactions our employees, distributors and third-party promoters have with hospitals, medical institutions and doctors, and they may try to increase sales volumes of our products through means that constitute violations of United States, PRC or other countries’ anti-corruption and related laws. If our employees, distributors or third-party promoters engage in corrupt or other improper conduct that results in violation of applicable anti-corruption laws in the United States, PRC or other jurisdictions, our reputation could be harmed. Furthermore, we could be held liable for actions taken by our employees, distributors or third-party promoters, which could expose us to regulatory investigations and penalties.
Although we have policies and procedures designed to ensure that we, our employees and our agents comply with anti-bribery laws, there is no assurance that such policies or procedures will prevent our agents, employees and intermediaries from engaging in bribery activities. Our procedures and controls to monitor anti-bribery and corruption compliance may fail to protect us from reckless or criminal acts committed by our employees or agents. If we, due to either our own deliberate or inadvertent acts or those of others, fail to comply with applicable anti-bribery and corruption laws, our reputation could be harmed and we could incur criminal or civil penalties, including but not limited to imprisonment, criminal and civil fines, suspension of our ability to do business with the government, denial of government reimbursement for our products and/or exclusion from participation in government healthcare programs, other sanctions and/or significant expenses, which could have a material adverse effect on our business, including our financial condition, results of operations, cash flows and prospects.

Any failure to comply with applicable regulations and industry standards or obtain various licenses and permits could harm our reputation and our business, results of operations and prospects.

        A number of governmental agencies or industry regulatory bodies in the United States, and in non-U.S. jurisdictions including the PRC and European Union, impose strict rules, regulations and industry standards governing pharmaceutical and biotechnology research and development activities, which apply to us. Our failure to comply with such regulations could result in the termination of ongoing research, administrative penalties imposed by regulatory bodies or the disqualification of data for submission to regulatory authorities. This could harm our reputation, prospects for future work and operating results. For example, if we were to treat research animals inhumanely or in violation of international standards set out by the Association for Assessment and Accreditation of Laboratory Animal Care, it could revoke any such accreditation and the accuracy of our animal research data could be questioned.


If we or our CROs or contract manufacturing organizations ("CMOs") fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could have a material adverse effect on the success of our business.

We and third parties, such as our CRO,CROs or CMOs, are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes. In addition, our construction projects can only be put into operation after certain regulatory procedures with the relevant administrative authorities in charge of environmental protection, health and safety have been completed. Our operations involve the use of hazardous and flammable materials, including chemicals and radioactive and biological materials. Our operations also produce hazardous waste products. We generally contract with third parties for the disposal of these materials and wastes. We also store certain low level radioactive waste at our facilities until the materials can be properly disposed of. We cannot eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting from our use of hazardous materials, we could be held liable for any resulting damages, and any liability could exceed our resources.resources or insurance coverage. We also could incur significant costs associated with civil or criminal fines and penalties.

Although we maintain workers'workers’ compensation insurance to cover us for costs and expenses that we may incur due to injuries to our employees resulting from the use of or exposure to hazardous materials, this insurance may not provide adequate coverage against potential liabilities. We do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us in connection with our storage, use or disposal of biological or hazardous or radioactive materials.

In addition, we may be required to incur substantial costs to comply with current or future environmental, health and safety laws and regulations. These current or future laws and regulations may impair our research, development or production efforts. Failure to comply with these laws and regulations also may result in substantial fines, penalties or other sanctions.

If we face allegations of noncompliance with the law and encounter sanctions, our reputation, revenues and liquidity may suffer, and our drugs could be subject to restrictions or withdrawal from the market.

        Any government investigation of alleged violations of law could require us to expend significant time and resources in response, and could generate negative publicity. Any failure to comply with ongoing regulatory requirements may significantly and adversely affect our ability to commercialize and generate revenues from our drugs. If regulatory sanctions are applied or if regulatory approval is withdrawn, the value of our company and our operating results will be adversely affected. Additionally, if we are unable to generate revenues from our product sales, our potential for achieving profitability will be diminished and the capital necessary to fund our operations will be increased.

Our internal computerinformation technology systems, or those used by our CROs, CMOs, or other collaborators, contractors or consultants, may fail or suffer security breaches.

breaches, which could result in a material disruption of our product development and commercialization programs.

Despite the implementation of security measures, our internal computerinformation technology systems and those of our future CROs, CMOs and other collaborators, contractors and consultants are vulnerable to damage from internal or external events, such as computer viruses, unauthorized access, natural disasters, terrorism, war, and unauthorized access.telecommunication and electrical failures, which compromise the confidentiality, integrity and availability of the systems. Although to our knowledge we have not experienced any such material system failure or security breach to date, if such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our research, development, programsmanufacturing, gaining regulatory approval for our drug candidates and commercialization efforts and our business operations.
In the ordinary course of our business, we collect and store sensitive data, including, among other things, legally protected patient health information, personally identifiable information about our employees, intellectual property, and proprietary business information. We manage and maintain our applications and data utilizing on-site systems and outsourced vendors.

These applications and data encompass a wide variety of business-critical information including research and development information, commercial information and business and financial information. Because information systems, networks and other technologies are critical to many of our operating activities, shutdowns or service disruptions at our company or vendors that provide information systems, networks, or other services to us pose increasing risks. Such disruptions may be caused by events such as computer hacking, phishing attacks, ransomware, dissemination of computer viruses, worms and other destructive or disruptive software, denial of service attacks and other malicious activity, as well as power outages, natural disasters (including extreme weather), terrorist attacks or other similar events. Such events could cause loss of data, damage to system and data and leave us unable to utilize key business systems or access important data needed to operate our business, including conducting research and development, gaining regulatory approval for our drug candidates or manufacturing and selling our products. Our CROs, CMOs or other collaborators, contractors or consultants may face similar risks, and service disruptions or security breaches of their systems could adversely affect our security, leave us without access to important systems, products, raw materials, components, services or information or expose our confidential data. In addition, system redundancy may be ineffective or inadequate, and our disaster recovery planning may not be sufficient to cover all eventualities. Significant events could result in a disruption of our operations, damage to our reputation or a loss of revenues. In addition, we may not have adequate insurance coverage to compensate for any losses associated with such events.
We could be subject to risks caused by misappropriation, misuse, leakage, falsification or intentional or accidental release or loss of information maintained in the information systems and networks of our company and our vendors, including personal information of our employees and patients, and company and vendor confidential data. In addition, outside parties may attempt to penetrate our systems or those of our vendors or fraudulently induce our personnel or the personnel of our vendors to disclose sensitive information in order to gain access to our data and/or systems. Like other companies, we have on occasion experienced, and will continue to experience, threats to our data and systems, including malicious codes and viruses, phishing, business email compromise attacks, or other cyber-attacks. The number and complexity of these threats continue to increase over time. If a material breach of our information technology systems or those of our vendors occurs, the market perception of the effectiveness of our security measures could be harmed and our reputation and credibility could be damaged. We could be required to expend significant amounts of money and other resources to respond to these threats or breaches and to repair or replace information systems or networks and could suffer financial loss or the loss of valuable confidential information. In addition, we could be subject to regulatory actions and/or claims made by individuals and groups in private litigation involving privacy issues related to data collection and use practices and other data privacy laws and regulations, including claims for misuse or inappropriate disclosure of data, as well as unfair or deceptive practices. Although we develop and maintain systems and controls designed to prevent these events from occurring, and we have a process to identify and mitigate threats, the development and maintenance of these systems, controls and processes is costly and requires ongoing monitoring and updating as technologies change and efforts to overcome security measures become increasingly sophisticated. Moreover, despite our efforts, the possibility of these events occurring cannot be eliminated entirely. As we outsource more of our information systems to vendors, engage in more electronic transactions with payors and patients, and rely more on cloud-based information systems, the related security risks will increase and we will need to expend additional resources to protect our technology and information systems. In addition, there can be no assurance that our internal information technology systems or those of our CROs, CMOs and other collaborators, contractors, or our consultants’ efforts to implement adequate security and control measures, will be sufficient to protect us against breakdowns, service disruption, data deterioration or loss in the event of a system malfunction, or prevent data from being stolen or corrupted in the event of a cyberattack, security breach, industrial espionage attacks or insider threat attacks that could adversely affect our business and operations and/or result in the loss or exposure of critical, proprietary, private, confidential or otherwise sensitive data, which could result in financial, legal, business or reputational harm to us.
Our failure to comply with data protection laws and regulations could lead to government enforcement actions and significant penalties against us, and adversely impact our operating results.
The regulatory framework for the collection, use, safeguarding, sharing, transfer and other processing of personal information worldwide is rapidly evolving and is likely to remain uncertain for the foreseeable future. Regulatory authorities in virtually every jurisdiction in which we operate have implemented and are considering a number of legislative and regulatory proposals concerning personal data protection.
In the United States, we are subject to laws and regulations that address privacy, personal information protection and data security at both the federal and state levels. Numerous laws and regulations, including security breach notification laws, health information privacy laws, and consumer protection laws, govern the collection, use, disclosure and protection of health-related and other personal information. Given the variability and evolving state of these laws, we face uncertainty as to the exact interpretation of the new requirements, and we may be unsuccessful in implementing all measures required by regulators or courts in their interpretation.

Regulatory authorities in Europe have implemented and are considering a number of legislative and regulatory proposals concerning data protection. For example, the lossGeneral Data Protection Regulation (EU) 2016/679 ("GDPR"), which became effective in May 2018, imposes a broad range of clinical trialstrict requirements on companies subject to the GDPR, such as us, including, but not limited to, requirements relating to having legal bases for processing personal information, including personal health data, relating to identifiable individuals and transferring such information outside the European Economic Area (including to the United States), providing information to those individuals regarding the data processing of their personal information, implementing safeguards to keep personal information secure and confidential, having data processing agreements with third parties who process personal information, acquiring consent of the individuals to whom the personal data relates, responding to individuals’ requests to exercise their rights in respect of their personal information, reporting security breaches involving personal data to the competent national data protection authority and affected individuals, and recordkeeping. The GDPR imposes strict rules on the transfer of personal data to countries outside the European Economic Area, including the United States, and also imposes restrictions on cross-border data transfers. The GDPR substantially increases the penalties to which we could be subject in the event of any non-compliance, including fines of up to €10 million or up to 2% of our total worldwide annual turnover for certain comparatively minor offenses, or up to €20 million or up to 4% of our total worldwide annual turnover for more serious offenses. The GDPR also confers a private right of action on data subjects and consumer associations to lodge complaints with supervisory authorities, seek judicial remedies, and obtain compensation for damages resulting from completedviolations of the GDPR. Given the new law, we face uncertainty as to the exact interpretation of the new requirements, and we may be unsuccessful in implementing all measures required by data protection authorities or future clinical trialscourts in interpretation of the new law. Despite our best efforts to comply, there is a risk that we may be subject to fines and penalties, litigation, and reputational harm in connection with our European activities. The GDPR may increase our responsibility and liability in relation to personal data that we process where such processing is subject to the GDPR, and we may be required to put in place additional mechanisms to ensure compliance with the GDPR, including as implemented by individual countries. National laws of member states of the EU are in the process of being adapted to the requirements under the GDPR. Because the GDPR specifically gives member states flexibility with respect to certain matters, national laws may partially deviate from the GDPR and impose different obligations from country to country, leading to additional complexity and uncertainty. Further, the United Kingdom’s decision to leave the EU, often referred to as Brexit, has created uncertainty with regard to data protection regulation in the United Kingdom. In particular, it is unclear how data transfers to and from the United Kingdom will be regulated now that the United Kingdom has left the EU.
Regulatory authorities in China have implemented and are considering a number of legislative and regulatory proposals concerning data protection. For example, the Cyber Security Law of the PRC (the "Cyber Security Law"), which became effective in June 2017, created China’s first national-level data protection for “network operators,” which may include all organizations in China that provide services over the internet or another information network. Numerous regulations, guidelines and other measures are expected to be adopted under the umbrella of the Cyber Security Law. Drafts of some of these measures have now been published, including the draft rules on cross-border transfer of personal information published by the China Cyberspace Administration in 2017 and 2019, which may, upon enactment, require security review before transferring human health-related data out of China. In addition, certain industry- specific laws and regulations affect the collection and transfer of personal data in China. For example, the Regulation on the Administration of Human Genetic Resources promulgated by the State Council (the “HGR Regulation”), which became effective on July 1, 2019, applies to activities that involve sampling, biobanking, use of HGR materials and associated data, in China, and provision of such to foreign parties. The HGR Regulation prohibits both onshore or offshore entities established or actually controlled by foreign entities and individuals from sampling or biobanking any China HGR in China and require approval for the sampling of certain HGR and biobanking of all HGR by Chinese parties. Approval for any export or cross- border transfer of the HGR material is also required. The HGR Regulation also requires that foreign parties should ensure the full participation of Chinese parties in international collaborations and all records and data must be shared with the Chinese parties. If the Chinese parties fail to comply with data protection laws, regulations and practice standards, and our research data is obtained by unauthorized persons, used or disclosed inappropriately or destroyed, it could result in delaysa loss of our confidential information and subject us to litigation and government enforcement actions. It is possible that these laws may be interpreted and applied in a manner that is inconsistent with our regulatory approvalpractices, potentially resulting in confiscation of HGR samples and associated data and administrative fines, disgorgement of illegal gains, or temporary or permanent debarment of our entities and responsible persons from further HGR projects. In addition, the interpretation and application of data protection laws in China and elsewhere are often uncertain and in flux.
We expect that these areas will receive greater attention and focus from regulators going forward and we will continue to face uncertainty as to whether our efforts to comply with evolving obligations under global data protection, privacy and significantlysecurity laws will be sufficient. Any failure or perceived failure by us to comply with applicable laws and regulations could result in reputational damage or proceedings or actions against us by governmental entities, individuals or others. These proceedings or actions could subject us to significant civil or criminal penalties and negative publicity, result in the delayed or halted transfer or confiscation of certain personal information, require us to change our business practices, increase our costs to recover or reproduce the data. Likewise, we partially rely onand materially harm our third-party research institution collaborators for researchbusiness, prospects, financial condition and developmentresults of operations. In addition, our drug candidatescurrent and future

relationships with customers, vendors, pharmaceutical partners and other third parties forcould be negatively affected by any proceedings or actions against us or current or future data protection obligations imposed on them under applicable law, including the manufacture of our drug candidatesGDPR and to conduct clinical trials,Cyber Security Law. In addition, a data breach affecting personal information, including health information, could result in significant management resources, legal and similar events relating to their computer systemsfinancial exposure and reputational damage that could alsopotentially have a materialan adverse effect on our business. To
We may be restricted from transferring our scientific data from China abroad.
In March 2018, the General Office of the State Council promulgated the Measures for the Management of Scientific Data (the "Scientific Data Measures"), which provides a broad definition of scientific data and relevant rules for the management of scientific data in China. According to the Scientific Data Measures, enterprises in China must seek governmental approval before any scientific data involving a state secret may be transferred abroad or to foreign parties. Further, any researcher conducting research funded at least in part by the Chinese government is required to submit relevant scientific data for management by the entity to which such researcher is affiliated before such data may be published in any foreign academic journal. Given that the term state secret is not clearly defined, if and to the extent our research and development of drug candidates will be subject to the Scientific Data Measures and any subsequent laws as required by the relevant government authorities, we cannot assure you that any disruptionwe can always obtain relevant approvals for sending scientific data (such as the results of our preclinical studies or security breach wereclinical trials conducted within China) abroad or to our foreign partners in China. If we are unable to obtain necessary approvals in a timely manner, or at all, our research and development of drug candidates may be hindered, which may materially and adversely affect our business, results of operations, financial condition and prospects. If the relevant government authorities consider the transmission of our scientific data to be in violation of the requirements under the Scientific Data Measures, we may be subject to fines and other administrative penalties imposed by those government authorities.
If we or parties on whom we rely fail to maintain the necessary licenses for the development, production, sales and distribution of our products, our ability to conduct our business could be materially impaired.
We are required to obtain, maintain and renew various permits, licenses and certificates to develop, produce, promote and sell our products. Third parties, such as distributors, third-party promoters and third-party manufacturers, on whom we may rely to develop, produce, promote, sell and distribute our products may be subject to similar requirements. We and third parties on whom we rely may be also subject to regular inspections, examinations, inquiries or audits by the regulatory authorities, and an adverse outcome of such inspections, examinations, inquiries or audits may result in athe loss or non-renewal of the relevant permits, licenses and certificates. Moreover, the criteria used in reviewing applications for, or damagerenewals of permits, licenses and certificates may change from time to our datatime, and there can be no assurance that we or applications,the parties on whom we rely will be able to meet new criteria that may be imposed to obtain or inappropriate disclosurerenew the necessary permits, licenses and certificates.

materially impaired. Furthermore, if the interpretation or implementation of existing laws and regulations change, or new regulations come into effect, requiring us or parties on whom we rely to obtain any additional permits, licenses or certificates that were previously not required to operate our business, there can be no assurance that we or parties on whom we rely will successfully obtain such permits, licenses or certificates.

Business disruptions could seriously harm our future revenue and financial condition and increase our costs and expenses.

Our operations, and those of our third-party research institution collaborators, CROs, CMOs, suppliers and other contractors and consultants, could be subject to earthquakes, power shortages, telecommunications failures, water shortages, floods, hurricanes, typhoons, fires, extreme weather conditions, medical epidemics and other natural or man-made disasters, public health epidemics or other business interruptions, for which we are predominantly self-insured. In addition, we partially rely on our third-party research institution collaborators for conducting research and development of our drug candidates, and they may be affected by such business interruptions, government shutdowns or withdrawn funding. The occurrence of any of these business disruptionsinterruptions could seriously harm our operations and financial condition and increase our costs and expenses. We partially rely on third-party manufacturers to produce and process our drugs and drug candidates. Our ability to obtain clinical supplies of our drugs and drug candidates could be disrupted if the operations of these suppliers are affected by a man-made or natural disasterdisasters, public health epidemics or other business interruption. A large portion of our operations is located in a single facility in Changping, Beijing, PRC.interruptions. Damage or extended periods of interruption to our or our vendors' corporate, development, research or researchmanufacturing facilities due to fire, natural disaster, power loss, communications failure, unauthorized entry, public health epidemics or other events could cause us to delay or cease development or delay developmentcommercialization of some or all of our drugs and drug candidates. Although we maintain property damage and business interruption insurance coverage on these facilities, our insurance might not cover all losses under such circumstances and our business may be seriously harmed by such delays and interruption.

If product For example, the COVID-19 outbreak could negatively impact our business and our financial performance. Our clinical development and commercial efforts could be delayed or otherwise negatively impacted, as patients may be reluctant to go to the hospitals to receive treatment. Additionally, the commercial or clinical supply of our drugs and drug candidates could be


negatively impacted due to reduced operations or a shutdown of our or our third-party manufacturing facilities, distribution channels and transportation systems, or shortages of raw materials and drug product.
Our business and results of operations could be adversely affected by public health crises and natural catastrophes or other disasters outside of our control in the locations in which we, our suppliers, CROs, CMOs and other contractors operate.

Our global operations expose us to risks associated with public health crises, such as epidemics and pandemics, natural catastrophes, such as earthquakes, hurricanes, typhoons, or floods,  or other disasters such as fires, explosions and terrorist activity or war that are outside of our control, including government reactions due to such events. Our business operations and those of our suppliers, CROs, CMOs and other contractors may potentially suffer interruptions caused by any of these events.
In December 2019, the COVID-19 virus began to impact the population of Wuhan, China and other cities. The COVID-19 outbreak has caused the Chinese government to implement various temporary measures, including quarantines of Wuhan and surrounding areas, travel and work restrictions at the national level, and the shutdown of certain businesses. As a result, our operations in China have and may continue to be impacted by delays in business activities and commercial transactions, workplace disruptions, and general uncertainties about the adverse impact on the Chinese economy. We expect that the COVID-19 outbreak will have a negative impact on our operations in China, including clinical trial recruitment and participation, regulatory interactions and inspections, and commercial revenue, particularly in the first quarter of 2020 and possibly longer depending on the scope and duration of the disruption.
Currently, it is unclear if the Chinese government will further extend any of the current restrictions or if further measures will be put into place.  Additionally, the COVID-19 virus has spread to other countries outside of China, which has caused a broader impact globally, such as restrictions on travel and quarantine policies put into place by businesses and governments. The potential economic impact brought by and the duration of the COVID-19 outbreak may be difficult to assess or predict, where actual effects will depend on many factors beyond our control. The extent to which the COVID-19 outbreak impacts our operations remains uncertain, and we are closely monitoring its impact on us. Our business and results of operations could be adversely affected directly, as well as to the extent that the COVID-19 outbreak or any other epidemic harms the Chinese, United States, and global economy in general.
Product liability claims or lawsuits are brought againstcould cause us we mayto incur substantial liabilities and may be required to limit commercialization of our drug candidates.

liabilities.

We face an inherent risk of product liability as a result of the commercialization of our drugs in China and the United States and the clinical testing and any future commercialization of our drug candidates and will face an even greater risk if we commercialize any drugs.globally. For example, we may be sued if our drugs or drug candidates cause or are perceived to cause injury or are found to be otherwise unsuitable during clinical testing, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the drug, negligence, strict liability or a breach of warranties. Claims could also be asserted under stateapplicable consumer protection acts. If we cannot successfully defend ourselves against or obtain indemnification from our collaborators for product liability claims, we may incur substantial liabilities or be required to limit commercialization of our drugs and drug candidates. Even successful defense would require significant financial and management resources. Regardless of the merits or eventual outcome, liability claims may result in:


Our inability to obtain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or inhibit the commercialization of our drugs we develop, alone or with collaborators.and drug candidates. Although we currently hold $10 million in product liability coverage which we believe to be sufficient in the aggregate,light of our current products and clinical programs, the amount of such insurance coverage may not be adequate, and we may be unable to maintain such insurance at a reasonable cost or in an amount adequate to satisfy any liability that may arise, or we may not be able to obtain additional or replacement insurance at a reasonable cost, if at all. We intend to expand our insurance coverage for products to include the sale of commercial products if we obtain marketing approval for our product candidates in development, but we may be unable to obtain commercially reasonable product liability insurance for any products approved for marketing. Our insurance policies may also have various exclusions, and we may be subject to a product liability claim for which we have no coverage. We may have to pay any amounts awarded by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered by our insurance, and we may not have, or be able to obtain, sufficient capital to pay such amounts. Even if our agreements with any future corporate collaborators entitle us to indemnification against losses, such indemnification may not be available or adequate should any claim arise.

We have limited insurance coverage, and any claims beyond our insurance coverage may result in our incurring substantial costs and a diversion of resources.

        We maintain property insurance policies covering physical damage to, or loss of, our buildings and their improvements, equipment, office furniture and inventory. We hold employer's liability insurance generally covering death or work-related injury of employees. We hold public liability insurance covering certain incidents involving third parties that occur on or in the premises of the company. We hold directors and officers liability insurance. We do not maintain key-man life insurance on any of our senior management or key personnel, or business interruption insurance. Our insurance coverage may be insufficient to cover any claim for product liability, damage to our fixed assets or employee injuries. Any liability or damage to, or caused by, our facilities or our personnel beyond our insurance coverage may result in our incurring substantial costs and a diversion of resources.

We may market our drugs, if approved, globally, and we will beare subject to the risks of doing business globally.

Because we operate in China and other countries outside of the United States.

        Because we intend to market drugs, if approved, globally,States, our business is subject to risks associated with doing business globally. Accordingly, our business and financial results in the future could be adversely affected due to a variety of


factors, including:


Our business, financial condition and results For example, the withdrawal of operations may be adversely affected by the downturn in the global economy.

        The global financial markets experienced significant disruptions in 2008 and the United States, Europe and other economies went into recession. The recoveryKingdom from the lowsEU effective on January 31, 2020, commonly referred to as “Brexit,” may cause increased economic volatility, affecting our operations and business. In addition, on July 27, 2017, the United Kingdom Financial Conduct Authority, which regulates London Interbank Offered Rate (“LIBOR”), announced that it will no longer require banks to submit rates for the calculation of 2008 and 2009 was unevenLIBOR to the LIBOR administrator after 2021, and it is facing new challenges, including the escalation of the European sovereign debt crisis since 2011 and the United Kingdom's decision to withdraw from the European Union. It is unclear whether the European sovereign debt crisisanticipated that LIBOR will be containedphased out and what effects it and the United Kingdom's decision to withdraw from the European Union may have. There is considerable uncertainty over the long-term effects of the expansionary monetary and fiscal policies thatreplaced by 2022. While various replacement reference rates have been adopted byproposed, an alternative reference rate to LIBOR has not yet been widely adopted. As such, the central banks andreplacement of LIBOR could have an adverse effect on the market for, or value of, LIBOR-linked financial authorities of some of the world's leading economies, including China's. Economic conditions in United States and China are sensitive to global economic conditions. Although we are uncertain about the extent to which the global financial market disruption and slowdown of the U.S. or Chinese economy may impact our business in the long term, there is a risk that our business, results of operations and prospects would be materially and adversely affected by the global economic downturn and the slowdown of the U.S. or Chinese economy.

Recent developments relating to the United Kingdom's referendum vote in favor of withdrawal from the European Union could adversely affect us.

        The United Kingdom held a referendum on June 23, 2016 in which a majority voted for the United Kingdom's withdrawal from the European Union (referred to as "Brexit"). As a result of this vote, negotiations are expected to commence to determine the terms of the United Kingdom's withdrawal from the European Union as well as its relationship with the European Union going forward, including the terms of trade between the United Kingdom and the European Union. The effects of Brexit have been and are expected to continue to be far-reaching. Brexit and the perceptions as to its impact may adversely affect business activity and economic conditions in Europe and globally and could continue to contribute to instability in global financial and foreign exchange markets. Brexit could also have the effect of disrupting the free movement of goods, services and people between the United Kingdom and the European Union; however, the full effects of Brexit are uncertain and will depend on any agreements the United Kingdom may make to retain access to European Union markets.

        In addition, we expect that Brexit could lead to legal uncertainty and potentially divergent national laws and regulations as the United Kingdom determines which European Union laws to replicate or replace. If the United Kingdom were to significantly alter its regulations affecting the pharmaceutical industry, we could face significant new costs. It may also be time-consuming and expensive for us to alter our internal operations in order to comply with new regulations. Altered regulations could also add time and expense to the process by which our product candidates receive regulatory approval in the United Kingdom and European Union. Similarly, it is unclear at this time what Brexit's impact will have on our intellectual property rights and the process for obtaining, maintaining and defending such rights. It is possible that certain intellectual property rights, such as trademarks, granted by the European Union will cease being enforceable in the United Kingdom absent special arrangements to the contrary, and we are required to refile our trademarks and other intellectual property applications domestically in the United Kingdom. With regard to existing patent rights, the effect of Brexit should

be minimal considering enforceable patent rights are specific to the United Kingdom, whether arising out of the European Patent Office or directly through the United Kingdom patent office.

        Lastly, as a result of Brexit, other European countries may seek to conduct referenda with respect to their continuing membership in the European Union. Given these possibilities and others we may not anticipate, as well as the lack of comparable precedent, the full extent to which our business, results of operations and financial condition could be adversely affected by Brexit is uncertain.

We manufacture and intend to continue to manufacture ourselves at least a portion of our drug candidates ourselves.and our drugs, if approved. Delays in completing and receiving regulatory approvals for our manufacturing facilityfacilities, or damage to, destruction of or interruption of production at such facilities, could delay our development plans and thereby limit our revenues and growth.

or commercialization efforts.

We currently lease an approximately 140 square meterhave manufacturing facilityfacilities in Beijing, PRC, which producesGuangzhou, and supplies preclinical and clinical trial materials for some of our small molecule drug candidates. In addition, to increase our manufacturing capabilities, we lease an approximately 11,000 square meter space and are building a manufacturing facility in Suzhou, China, where we intend to produce drug candidates for clinical or, in the future, commercial use. This facility consists of one oral-solid-dosage production line for small molecule drug products and one pilot plant for monoclonal antibody drug substances. This new manufacturing facility is expected to be completed in 2017. This projectChina. These facilities may encounter unanticipated delays and cost more than expectedexpenses due to a number of factors, including regulatory requirements. If construction or expansion, regulatory evaluation and/or approval of our new facility isfacilities are delayed, we may not be able to manufacture sufficient quantities of our drugs and drug candidates, which would limit our development and commercialization activities and our opportunities for growth. Suzhou Industrial Park Biotech Development Co., Ltd. and China Construction Bank have agreed to lend us RMB 120 million for the construction of the Suzhou manufacturing facility and the procurement of equipment. Cost overruns associated with constructing or maintaining our Suzhou facilityfacilities could require us to raise additional funds from other sources.

In addition to the similar manufacturing risks described in "—Risks“Risks Related to Our Reliance on Third Parties," our manufacturing facilities will be subject to inspection in connection with clinical development and new drug approvals and ongoing, periodic inspection by the FDA, CFDA,NMPA, EMA or other comparable regulatory agencies to ensure compliance with cGMP.GMP and other regulatory requirements. Our failure to follow and document our adherence to such cGMPGMP regulations or other regulatory requirements may lead to significant delays in the availability of products for clinical or in the future, commercial use, may result in the termination of or a hold on a clinical trial, or may delay or prevent filing or approval of marketing applications for our drug candidates or the commercialization of our drugs. We also may encounter problems with the following:

achieving adequate or clinical-grade materials that meet FDA, CFDA,NMPA, EMA or other comparable regulatory agency standards or specifications with consistent and acceptable production yield and costs;

shortages of qualified personnel, raw materials or key contractors; and

ongoing compliance with cGMPGMP regulations and other requirements of the FDA, CFDA,NMPA, EMA or other comparable regulatory agencies.

Failure to comply with applicable regulations could also result in sanctions being imposed on us, including fines, injunctions, civil penalties, a requirement to suspend or put on hold one or more of our clinical trials, failure of regulatory authorities to grant marketing approval of our drug candidates, delays, suspension or withdrawal of approvals, supply disruptions, license revocation, seizures or recalls of drug candidates or drugs, operating restrictions and criminal prosecutions, any of which could harm our business.

Developing advanced manufacturing techniques and process controls is required to fully utilize our facilities. Advances in manufacturing techniques may render our facilities and equipment inadequate or obsolete.


To supply commercial quantities for our marketed products, produce our drugs in the quantities that we believe will be required to meet anticipated market demand, of anyand to supply clinical drug material to support the continued growth of our drug candidates if approved,clinical programs, we will need to increase, or "scale“scale up," the production process by a significant factor over the initial level of production.production, which will require substantial additional expenditures and various regulatory approvals and permits. If we are unable to do so, are delayed, or if the cost of this scale up is not economically feasible for us or we cannot find a third-party supplier, we may not be able to produce our drugs in a sufficient quantity to meet future demand.

If our manufacturing facilities, including our Suzhou manufacturing facility once completed, are damaged or destroyed or production at such facilities is otherwise interrupted, our business and prospects would be negatively affected.


In addition to the similar manufacturing risks described in "—Risks“-Risks Related to Our Reliance on Third Parties," if our manufacturing facilities or the equipment in them is damaged or destroyed, we may not be able to quickly or inexpensively replace our manufacturing capacity or replace it at all. In the event of a temporary or protracted loss of the facilities or equipment, we might not be able to transfer manufacturing to a third party. Even if we could transfer manufacturing to a third party, the shift would likely be expensive and time-consuming, particularly since the new facility would need to comply with the necessary regulatory requirements and we would need FDA, CFDA, EMA or and other comparable regulatory agency approval before selling any drugs manufactured at that facility. Such an event could delay our clinical trials or reduce our product sales if and when we are able to successfully commercialize one or more of our drug candidates.

sales. Any interruption in manufacturing operations at our manufacturing facilities could result in our inability to satisfy the demands of our clinical trials or commercialization. A number of factors could cause interruptions, including:

Any disruption that impedes our ability to manufacture our drug candidates or drugs in a timely manner could materially harm our business, financial condition and operating results.

Currently, we maintain insurance coverage against damage to our property, plant and equipment in the amount of up to RMB 100 million.amounts we believe are reasonable. However, our insurance coverage may not reimburse us, or may not be sufficient to reimburse us, for any expenses or losses we may suffer. We may be unable to meet our requirements for our drug candidates and drugs if there were a catastrophic event or interruption or failure of our manufacturing facilities or processes.

Future operating results could be negatively affected by changes in tax rates, the adoption of new tax legislation in the jurisdictions in which we operate, or exposure to additional tax liabilities.
The nature of our international operations subjects us to local, state, regional and national tax laws in jurisdictions around the world. Our future tax expense could be affected by changes in the mix of earnings in countries with differing statutory tax rates, changes in the valuation of deferred tax assets and liabilities or changes in tax laws or their interpretation. Additionally, tax rules governing cross-border activities are continually subject to modification as a result of both coordinated actions by governments and unilateral measures designed by individual countries, both intended to tackle concerns over base erosion and profit shifting (BEPS) and perceived international tax avoidance techniques. For example, the Cayman Islands has enacted the International Tax Co-operation (Economic Substance) Law (2020 Revision) (the “Economic Substance Law”), which originally took effect on January 1, 2019, and which is accompanied by Guidance on Economic Substance for Geographically Mobile Activities (Version 2.0; April 30, 2019) published by the Cayman Islands Tax Information Authority. The Economic Substance Law embraces a global initiative to combat BEPS and demonstrates the continued commitment of the Cayman Islands to international best practice. The Economic Substance Law provides that relevant entities that existed before January 1, 2019 and that had been conducting relevant activities by that date must comply with the economic substance requirements from July 1, 2019, and relevant entities that are established from January 1, 2019 onwards have to comply with the requirements from the date they commence the relevant activity. Although we believe that we currently are not required to comply with the economic substance requirements under the Economic Substance Law, we cannot predict any changes to the legislation or its interpretation in the future. If we are subject to compliance with the economic substance requirements in the future, our business and results of operations could be negatively impacted if we are required to make changes to our business in order to gain compliance or if we fail to comply.
We have received tax rulings from various governments that have jurisdictional authority over our operations. If we are unable to meet the requirements of such agreements, or if they expire or are renewed on less favorable terms, the result could negatively impact our future earnings. Additionally, the European Commission has opened formal investigations into specific tax rulings granted by several countries to specific taxpayers. While we believe that our rulings are different than those being discussed, the ultimate resolution of such activities cannot be predicted and could also have an adverse impact on future operating results.
If we are not able to successfully develop and commercialize Amgen’s oncology products in China, the expected benefits of the collaboration will not materialize.
We have a Collaboration Agreement with Amgen pursuant to which we and Amgen have agreed to collaborate on (i) the commercialization of Amgen’s oncology products XGEVA, KYPROLIS and BLINCYTO in China, and (ii) the global development and commercialization in China of 20 Amgen clinical- and late-preclinical-stage pipeline products. The Amgen transaction involves numerous risks, including unanticipated costs and diversion of our management’s attention from our other drug discovery and development business. There can be no assurance that we will be able to successfully develop and commercialize Amgen’s oncology products in China, which could disrupt our business and harm our financial results.
Moreover, we may not achieve the revenue and cost synergies expected from the Amgen transaction. These synergies are inherently uncertain, and are subject to significant business, economic and competitive uncertainties and contingencies, many of which are difficult to predict and are beyond our control. If we achieve the expected benefits, they may not be achieved within the anticipated time frame. Also, the synergies from the Amgen transaction may be offset by increases in other expenses,

operating losses or problems in our business unrelated to the Amgen transaction. As a result, there can be no assurance that such synergies will be achieved.
Risks Related to Our Doing Business in the PRC

The pharmaceutical industry in China is highly regulated, and such regulations are subject to change, which may affect approval and commercialization of our drugs.

        Our research operationsdrugs and manufacturing facilities aredrug candidates.

A large portion of our business is conducted in China, which we believe confers clinical, commercial and regulatory advantages.China. The pharmaceutical industry in China is subject to comprehensive government regulation and supervision, encompassing the approval, registration,


manufacturing, packaging, licensing and marketing of new drugs. See "Item 1—Business—Regulatory Framework and Structural Advantages of Being a China-Based Research and Development Organization" for a discussion of regulatory requirements that are applicable to our current and planned business activities in China. In recent years, the regulatory framework in China regarding the pharmaceutical industry has undergone significant changes, andwhich we expect that it will continue to undergo significant changes.continue. While we believe our strategies regarding pharmaceutical research, development, manufacturing and commercialization in China are aligned with the Chinese government's policies, they may in the future diverge, requiring a change in our strategies. Any such changes or amendmentschange may result in increased compliance costs on our business or cause delays in or prevent the successful research, development, manufacturing or commercialization of our drug candidates or drugs in China and reduce the current benefits we believe are available to us from developing and manufacturing drugs in China.

Chinese authorities have become increasingly vigilant in enforcing laws in the pharmaceutical industry and anyindustry. Any failure by us or our partners to maintain compliance with applicable laws and regulations or obtain and maintain required licenses and permits may result in the suspension or termination of our business activities in China. We believe our strategy and approach is aligned with the Chinese government's policies, but we cannot ensure that our strategy and approach will continueReports of what have come to be aligned.

viewed as significant quality-control failures by Chinese vaccine manufacturers have led to enforcement action against officials responsible for implementing national reforms favorable to innovative drugs (such as ours). While not directly affecting us, this macro-industry event could cause state or private resources to be diverted away from fostering innovation and be redirected toward regulatory enforcement, which could adversely affect our research, development, manufacturing and commercialization activities and increase our compliance cost.

Changes in the political and economic policies of the PRC government or in relations between China and the United States or other governments may materially and adversely affect our business, financial condition and results of operations and may result in our inability to sustain our growth and expansion strategies.

        A significant portion

Due to our extensive operations in China, our business, results of our operations, are in the PRC. Accordingly, our financial condition and results of operations are affectedprospects may be influenced to a large extentsignificant degree by economic, political, legal and legal developmentssocial conditions in the PRC.

        The PRC or changes in government relations between China and the United States or other governments, such as the ongoing trade war between the United States and China. China’s economy differs from the economies of most developed countries in many respects, including with respect to the extentamount of government involvement, level of development, growth rate, control of foreign exchange and allocation of resources. Although the PRC government has implemented measures emphasizing the utilization of market forces for economic reform, the reduction of state ownership of productive assets, and the establishment of improved corporate governance in business enterprises, a substantial portion of productive assets in China is still owned by the government. In addition, the PRC government continues to play a significant role in regulating industry development by imposing industrial policies. The PRC government also exercises significant control over China's economic growth by allocating resources, controlling payment of foreign currency-denominated obligations, setting monetary policy, regulating financial services and institutions and providing preferential treatment to particular industries or companies.

While the PRC economy has experienced significant growth inover the past threefour decades, growth has been uneven both geographicallyacross different regions and among various economic sectors of the economy.PRC. The PRC government has implemented various measures to encourage economic growthdevelopment and guide the allocation of resources. Some of these measures may benefit the overall PRC economy, but may also have a negative effect on us. OurFor example, our financial condition and results of operation couldoperations may be materially and adversely affected by government control over capital investments or changes in tax regulations that are currently applicable to us and consequently have a material adverse effect onus. In addition, in the past the PRC government implemented certain measures, including interest rate increases, to control the pace of economic growth. These measures may cause decreased economic activity in the PRC, which may adversely affect our businesses, financial conditionbusiness and results of operations.

operation. More generally, if the business environment in the PRC deteriorates from the perspective of domestic or international investment, or if relations between China and the United States or other governments deteriorate, our business in the PRC may also be adversely affected.

There are uncertainties regarding the interpretation and enforcement of PRC laws, rules and regulations.

A large portion of our operations are conducted in the PRC through our PRC subsidiaries, and are governed by PRC laws, rules and regulations. Our PRC subsidiaries are subject to laws, rules and regulations applicable to foreign investment in China. The PRC legal system is a civil law system based on written statutes. Unlike the common law system, prior court decisions may be cited for reference but have limited precedential value.


In 1979, the PRC government began to promulgate a comprehensive system of laws, rules and regulations governing economic matters in general. The overall effect of legislation over the past threefour decades has significantly enhanced the protections afforded to various forms of foreign investment in China. However, China has not developed a fully integrated legal system, and recently enacted laws, rules and regulations may not sufficiently cover all aspects of economic activities in China or may be subject to significant degrees of interpretation by PRC regulatory agencies. In particular, because these laws, rules and regulations are relatively new and often give the relevant regulator significant discretion in how to enforce them, and because of the limited number of published decisions and the nonbinding nature of such decisions, and because the laws, rules and regulations often give the relevant regulator significant discretion in how to enforce them, the interpretation and


enforcement of these laws, rules and regulations involve uncertainties and can be inconsistent and unpredictable. In addition, the PRC legal system is based in part on government policies and internal rules, some of which are not published on a timely basis or at all, and which may have a retroactive effect. As a result, we may not be aware of our violation of these policies and rules until after the occurrence of the violation.

        Any

The Foreign Investment Law of the PRC (the “Foreign Investment Law”) and the Implementing Rules to the Foreign Investment Law of the PRC (the “Implementing Rules”) came into force on January 1, 2020. The Foreign Investment Law and the Implementing Rules embody an expected regulatory trend to rationalize China’s foreign investment regulatory regime in line with prevailing international practice and the legislative efforts to unify the corporate legal requirements for both foreign and domestic investments. The Foreign Investment Law and its Implementing Rules are drafted at a level of general principle, there is a reasonable possibility that various other new regulations and legislative changes will be issued to implement the Foreign Investment Law. There are still uncertainties with respect to the interpretation and implementation of the Foreign Investment Law and the Implementing Rules. For example, the Foreign Investment Law and its Implementing Rules provide that foreign invested entities established according to the previous laws regulating foreign investment prior to the implementation of the Foreign Investment Law may maintain their structure and corporate governance within a five-year transition period. It is uncertain whether the PRC governmental authorities may require us to adjust the structure and corporate governance of certain of our PRC subsidiaries in such transition period. Failure to take timely and appropriate measures to meet any of these or similar regulatory compliance requirements could materially affect our current corporate governance practices and business operations and our compliance costs may increase significantly.
Additionally, the NMPA’s recent reform of the drug and approval system may face implementation challenges. The timing and full impact of such reforms is uncertain and could prevent us from commercializing our drug candidates in a timely manner.
In addition, any administrative and court proceedings in Chinathe PRC may be protracted, resulting in substantial costs and diversion of resources and management attention. Since PRC administrative and court authorities have significant discretion in interpreting and implementing statutory and contractual terms, it may be more difficult to evaluate the outcome of administrative and court proceedings and the level of legal protection we enjoy than in more developed legal systems. These uncertainties may impede our ability to enforce the contracts we have entered into and could materially and adversely affect our business, financial condition and results of operations.

Substantial uncertainties exist

Any failure to comply with respect to the enactment timetable, the final version, interpretation and implementation of draft PRC Foreign Investment Law and how it may impact the viability of our current corporate governance.

        The Ministry of Commerce published a discussion draft of the proposed Foreign Investment Law in January 2015 aiming to, upon its enactment, replace the trio of existing laws regulating foreign investment in China, namely, the Sino-foreign Equity Joint Venture Enterprise Law, the Sino-foreign Cooperative Joint Venture Enterprise Law and the Wholly Foreign-invested Enterprise Law, together with their implementation rules and ancillary regulations. The draft Foreign Investment Law embodies an expected PRC regulatory trend to rationalize its foreign investment regulatory regime in line with prevailing international practice and the legislative efforts to unify the corporate legal requirements for both foreign and domestic investments. The Ministry of Commerce has solicited comments on this draft and substantial uncertainties exist with respect to its enactment timetable, the final version, interpretation and implementation. The draft Foreign Investment Law, if enacted as proposed, may materially impact the viability of our current corporate governance if we, in the future, have PRC shareholders.

        Among other things, the draft Foreign Investment Law expands the definition of foreign investment and introduces the principle of "actual control" in determining whether a company is considered a foreign-invested enterprise, or an FIE. The draft Foreign Investment Law specifically provides that entities established in China but "controlled" by foreign investors will be treated as FIEs, whereas an entity set up in a foreign jurisdiction would nonetheless be, upon market entry clearance by the Ministry of Commerce or its local counterparts, treated as a PRC domestic investor provided that the entity is "controlled" by PRC entities and/or citizens. In this connection, "control" is broadly defined in the draft law to cover the following summarized categories: (1) holding 50% of more of the shares, equity or voting rights of the subject entity; (2) holding less than 50% of the voting rights of the subject entity but having the power to secure at least 50% of the seats on the board or other equivalent decision making bodies, or having the voting power to exert material influence on the board, the shareholders' meeting or other equivalent decision making bodies; or (3) having the power to exert


decisive influence, via contractual or trust arrangements, over the subject entity's operations, financial matters or other key aspects of business operations. Once an entity is determined to be an FIE, it will be subject to the foreign investment restrictions or prohibitions, if the FIE is engaged in the industry listed in the "negative list" which will be separately issued by the Chinese State Council later. Unless the underlying business of the FIE falls within the negative list, which calls for market entry clearance by the Ministry of Commerce or its local counterparts, prior approval from the government authorities as mandated by the existing foreign investment legal regime would no longer be required for establishment of the FIE.

        The draft Foreign Investment Law, if enacted as proposed, may also materially impact our corporate governance practice and increase our compliance costs. For instance, the draft Foreign Investment Law imposes stringent ad hoc and periodic information reporting requirements on foreign investors and the applicable FIEs. Aside from investment implementation report and investment amendment report that are required at each investment and alteration of investment specifics, an annual report is mandatory, and large foreign investors meeting certain criteria are required to report on a quarterly basis. Any company found to be non-compliant with these information reporting obligations may potentially be subject to fines and/or administrative or criminal liabilities, and the persons directly responsible may be subject to criminal liabilities.

PRC regulations relating toregarding our employee equity plans and investments in offshore companies by PRC residents may subject our futurethe PRC plan participants and PRC-resident beneficial owners or us to fines and other legal or administrative sanctions.

We and our directors, executive officers and other employees who are PRC subsidiariesresidents have participated in our employee equity plans. We are an overseas listed company, and therefore, we and our directors, executive officers and other employees who are PRC citizens or who have resided in the PRC for a continuous period of not less than one year and who have been granted restricted share units, restricted shares, options or other forms of equity incentives or rights to liabilityacquire equity are subject to the Notice on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Share Incentive Plan of Overseas Publicly Listed Company, according to which, employees, directors, supervisors and other management members participating in any share incentive plan of an overseas publicly listed company who are PRC citizens or penalties, limitwho are non-PRC citizens residing in the PRC for a continuous period of not less than one year, subject to limited exceptions, are required to register with the SAFE through a domestic qualified agent, which could be a PRC subsidiary of such overseas listed company, and complete certain other procedures. We also face regulatory uncertainties that could restrict our ability to inject capital intoadopt additional equity incentive plans for our PRC subsidiaries or limit our PRC subsidiaries' ability to increase their registered capital or distribute profits.

        SAFE promulgated the Circular on Relevant Issues Concerning Foreign Exchange Control on Domestic Residents' Offshore Investmentdirectors and Financing and Roundtrip Investment through Special Purpose Vehicles, or SAFE Circular 37, on July 4, 2014, which replaced the former circular commonly known as "SAFE Circular 75" promulgated by SAFE on October 21, 2005. SAFE Circular 37 requires PRC residents to register with local branches of SAFE in connection with their direct establishment or indirect control of an offshore entity, for the purpose of overseas investment and financing, with such PRC residents' legally owned assets or equity interests in domestic enterprises or offshore assets or interests, referred to in SAFE Circular 37 as a "special purpose vehicle." SAFE Circular 37 further requires amendment to the registration in the event of any significant changes with respect to the special purpose vehicle, such as increase or decrease of capital contributed by PRC individuals, share transfer or exchange, merger, division or other material event. In the event that a PRC shareholder holding interests in a special purpose vehicle fails to fulfill the required SAFE registration, the PRC subsidiaries of that special purpose vehicle may be prohibited from making profit distributions to the offshore parent and from carrying out subsequent cross-border foreign exchange activities, and the special purpose vehicle may be restricted in its ability to contribute additional capital into its PRC subsidiary. Moreover, failure to comply with the various SAFE registration requirements described above could result in liabilityemployees under PRC law for evasionlaw.

Some of foreign exchange controls.

        We believe that four of our existing shareholders, each of whom owns our ordinary shares as a result of exercising share options, are PRC residents under the Circular on Relevant Issues Concerning Foreign Exchange Control on Domestic Residents’ Offshore Investment and Financing and Roundtrip Investment through Special Purpose Vehicles ("SAFE Circular 37.37"). These four shareholders have undertaken to (i) apply to register with local SAFE branch or its delegated commercial bank as soon as possible after exercising their options, and (ii) indemnify and hold harmless us and our subsidiaries against any loss suffered arising from their failure to complete the registration. We do not have control over the foursuch shareholders and our other beneficial owners and cannot assure you that all of our PRC-resident beneficial owners have complied with, and will in the future comply with, SAFE Circular 37 and subsequent implementation rules. The failure of PRC-resident beneficial owners to register or amend their SAFE registrations in a timely manner pursuant to SAFE Circular 37 and subsequent implementation rules, or the failure of future PRC-resident beneficial owners of our


company to comply with the registration procedures set forth in SAFE Circular 37 and subsequent implementation rules, may subject such beneficial owners or our PRC subsidiaries to fines and legal sanctions. Furthermore, SAFE Circular 37 is unclear how this regulation, and any future regulation concerning offshore or cross-border transactions, will be interpreted, amended and implemented by the relevant PRC government authorities, and we cannot predict how these regulations will affect our business operations or future strategy. Failure to register or comply with relevant requirements may also limit our ability to contribute additional capital to our PRC subsidiaries and limit our PRC subsidiaries' ability to distribute dividends to us. These risks could in the future have a material adverse effect on our business, financial condition and results of operations.

Any failure to comply with PRC regulations regarding our employee equity incentive plans may subject the PRC plan participants or us to fines and other legal or administrative sanctions.

        We and our directors, executive officers and other employees who are PRC residents have participated in our employee equity incentive plans. Upon completion of our initial public offering, we became an overseas listed company. Pursuant to SAFE Circular 37, PRC residents who participate in share incentive plans in overseas non-publicly-listed companies may submit applications to SAFE or its local branches for the foreign exchange registration with respect to offshore special purpose companies. Our directors, executive officers and other employees who are PRC citizens or who have resided in the PRC for a continuous period of not less than one year and who have been granted restricted shares or options may follow SAFE Circular 37 to apply for the foreign exchange registration before our company became an overseas listed company. However, in practice, different local SAFE branches may have different views and procedures on the application and implementation of SAFE regulations, and there remains uncertainty with respect to its implementation. If we or our directors, executive officers or other employees who are PRC citizens or who have resided in the PRC for a continuous period of not less than one year and who have been granted restricted sharesequity awards or options, including but not limitedother rights to the four shareholders referred to above,acquire equity fail to register the employee equity incentive plans or their exercise of options or vesting of equity awards, or such PRC-resident beneficial owners fails to register or amend their SAFE registrations in a timely manner pursuant to SAFE Circular 37, we and such


employees and PRC-beneficial owners may be subject to (i) legal or administrative sanctions imposed by the SAFE or other PRC authorities, including fines; (ii) to restrictions on our cross-border investment activities; (iii) to limits on the ability of our wholly owned subsidiaries in China to distribute dividends or the proceeds from any reduction in capital, share transfer or liquidation to us; and (iv) to prohibitions on our ability to inject additional capital into these subsidiaries. Moreover, failure to comply with the various foreign exchange registration requirements described above could result in liability under PRC law for circumventing applicable foreign exchange restrictions. As a result, our business operations and our ability to distribute profits to you could be materially and adversely affected. Upon completion of our initial public offering, we became an overseas listed company, and therefore, we and our directors, executive officers and other employees who are PRC citizens or who have resided in the PRC for a continuous period of not less than one year and who have been granted restricted shares or options are subject to the Notice on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plan of Overseas Publicly Listed Company, issued by SAFE in February 2012, according to which, employees, directors, supervisors and other management members participating in any share incentive plan of an overseas publicly listed company who are PRC citizens or who are non-PRC citizens residing in China for a continuous period of not less than one year, subject to limited exceptions, are required to register with SAFE through a domestic qualified agent, which could be a PRC subsidiary of such overseas listed company, and complete certain other procedures. Failure to complete the SAFE registrations
We may subject them to fines and legal sanctions and may also limit our ability to make payments under our equity incentive plans or receive dividends or sales proceeds related thereto, or our ability to contribute additional capital into our wholly-foreign owned enterprises in China and limit our wholly-foreign owned enterprises' ability to distribute dividends to us. We also face regulatory uncertainties that could


restrict our ability to adopt additional equity incentive plans for our directors and employees under PRC law.

        In addition, the SAT has issued circulars concerning employee share options or restricted shares. Under these circulars, employees working in the PRC who exercise share options, or whose restricted shares vest, will be subject to PRC individual income tax. The PRC subsidiaries of an overseas listed company have obligations to file documents related to employee share options or restricted shares with relevant tax authorities and to withhold individual income taxes of those employees related to their share options or restricted shares. If the employees fail to pay, or the PRC subsidiaries fail to withhold applicable income taxes, the PRC subsidiaries may face sanctions imposed by the tax authorities or other PRC government authorities.

In the future, we may rely to some extent on dividends and other distributions on equity frompaid by our principal operatingPRC subsidiaries to fund offshoreany cash and financing requirements.

requirements we may have, and any limitation on the ability of our PRC subsidiaries to make payments to us could have a material and adverse effect on our ability to conduct our business.

We are a holding company incorporated in the Cayman Islands, and we may in the future rely to some extent on dividends and other distributions on equity frompaid by our principal operatingPRC subsidiaries for our offshore cash and financing requirements, including the funds necessary to pay dividends and other cash distributions to our shareholders fund inter-company loans,or to service any debt we may incur outside China and pay our expenses. The laws, rules and regulations applicable toincur. If any of our PRC subsidiaries incur debt on their own behalf in the future, the instruments governing the debt may restrict their ability to pay dividends or make other distributions to us. Under PRC laws and certain otherregulations, our PRC subsidiaries permit payments ofmay pay dividends only out of their retained earnings, if any,respective accumulated profits as determined in accordance with applicablePRC accounting standards and regulations.

        Under PRC laws, rules and regulations, each of our subsidiaries incorporated in China In addition, a wholly foreign-owned enterprise is required to set aside at least 10% of its accumulated after-tax profits each year, if any, to fund a certain statutory reserve fund, until the aggregate amount of such fund reaches 50% of its registered capital. Such reserve funds cannot be distributed to us as dividends. At its discretion, a wholly foreign-owned enterprise may allocate a portion of its net income each yearafter-tax profits based on PRC accounting standards to an enterprise expansion fund, certain statutory reserves. These reserves, together with the registered equity, are not distributable as cash dividends. Asor a result of these laws, rulesstaff welfare and regulations, our subsidiaries incorporated in China are restricted in their ability to transfer a portion of their respective net assets to their shareholders as dividends.bonus fund. In addition, registered share capital and capital reserve accounts are also restricted from withdrawal in the PRC, up to the amount of net assets held in each operating subsidiary. As of December 31, 2016,2019 and 2018, these restricted assets totaled RMB69.1$109.6 million ($10.0 million).

and $93.3 million, respectively.

Our PRC subsidiaries generate primarily all of their revenue in RMB, which is not freely convertible into other currencies. As a result, any restriction on currency exchange may limit the ability of our PRC subsidiaries to use their RMB revenues to pay dividends to us.
In response to the persistent capital outflow in the PRC and RMB’s depreciation against the U.S. dollar in the fourth quarter of 2016, China’s People’s Bank of China ("PBOC") and the SAFE promulgated a series of capital control measures, including stricter vetting procedures for domestic companies to remit foreign currency for overseas investments, dividends payments and shareholder loan repayments.
The PRC government may continue to strengthen its capital controls, and more restrictions and substantial vetting process may be put forward by the SAFE for cross-border transactions falling under both the current account and the capital account. Any limitation on the ability of our PRC subsidiaries to pay dividends or make other kinds of payments to us could materially and adversely limit our ability to grow, make investments or acquisitions that could be beneficial to our business, pay dividends, or otherwise fund and conduct our business.
The Enterprise Income Tax Law or the EIT Law(the "EIT Law") and its implementation rules both of which became effective on January 1, 2008, provide that China-sourced income of foreign enterprises, such as dividends paid by a PRC subsidiary to its equity holders that are non-PRC resident enterprises, will normally be subject to PRC withholding tax at a rate of 10%, unless any such foreign investor'sinvestor’s jurisdiction of incorporation has a tax treaty with China that provides for a different withholding arrangement. As a result, dividends paid to us by our PRC subsidiaries are expected to be subject to PRC withholding tax at a rate of 10%.

Pursuant to the Arrangement between Mainland China and Hong Kong Special Administrative Region for the Avoidance of Double Taxation and Prevention of Fiscal Evasion with respect to Taxes on Income or the(the "Hong Kong Tax Treaty,"Treaty"), BeiGene (Hong Kong) Co., Limited,HK, the shareholder of some of our PRC subsidiaries, may be subject to a withholding tax at a rate of 5% on dividends received from our PRC operating subsidiaries as a Hong Kong tax resident. Pursuant to the Hong Kong Tax Treaty, subject to certain conditions, this reduced withholding tax rate will be available for dividends from PRC entities provided that the recipient can demonstrate it is a Hong Kong tax resident and it is the beneficial owner of the dividends. The SAT promulgated SAT Circular 9 in February 2018, which became effective from April 2018 and stipulates that in determining whether a non-resident enterprise has the status as a beneficial owner, comprehensive analysis shall be conducted based on the factors listed therein and the actual circumstances of the specific case shall be taken into consideration. Specifically, it expressly excludes an agent or a designated payee from being considered as a “beneficial owner.” BeiGene (Hong Kong) Co., LimitedHK currently does not hold a Hong Kong tax resident certificate from the Inland Revenue Department of Hong Kong and there is no assurance that the reduced withholding tax rate will be available.

        Furthermore, if our subsidiaries in China incur debt on their own behalf in the future, the instruments governing the debt may restrict their ability to pay dividends or make other payments to us. Any limitation on the ability of our subsidiaries to distribute dividends or other payments to us in


the future could materially and adversely limit our ability to make investments or acquisitions that could be beneficial to our businesses, pay dividends, or otherwise fund and conduct our business.

We may be treated as a resident enterprise for PRC tax purposes under the EIT Law and we may therefore be subject to PRC income tax on our worldwide taxable income at a rateincome. Dividends payable to foreign investors and gains on the sale of 25%.

our ADSs or ordinary shares by our foreign investors may become subject to PRC tax.

Under the EIT Law an enterprise established outside Chinathe PRC with "de“de facto management bodies"bodies” within Chinathe PRC is considered a "resident“resident enterprise," meaning that it is treated in a manner similar to a Chinese enterprise for PRC enterprise income tax or EIT,("EIT") purposes. The implementing rules of the EIT Law define "de“de facto management bodies"bodies” as "management“management bodies that exercise substantial and overall management and control over the production and operations, personnel, accounting, and properties"properties” of the enterprise. In addition, the Notice Regarding the Determination of Chinese-Controlled Offshore Incorporated Enterprises as PRC Tax Resident Enterprises on the Basis of De Facto Management Bodies or ("Circular 82,82") specifies that certain Chinese-controlled offshore incorporated enterprises, defined as enterprises incorporated under the laws of foreign countries or territories and that have PRC enterprises or enterprise groups as their primary controlling shareholders, will be classified as resident enterprises if all of the following are located or resident in China: (i) senior management personnel and departments that are responsible for daily production, operation and management; (ii) financial and personnel decision-making bodies; (iii) key properties, accounting books, company seal, and minutes of board meetings and shareholders'shareholders’ meetings; and (iv) half or more of senior management or directors having voting rights. On July 27, 2011, the SAT issued Administrative MeasuresThe State Administration of Enterprise Income Tax of Chinese-Controlled Offshore Incorporated Resident Enterprises (Trial), or Bulletin 45, which became effective on September 1, 2011 and was most recently amended on October 1, 2016, to provideTaxation (the "SAT") has subsequently provided further guidance on the implementation of Circular 82. Bulletin 45 clarifies certain issues related to determining PRC resident enterprise status, including which competent tax authorities are responsible for determining offshore incorporated PRC resident enterprise status, as well as post-determination administration. In 2014, the SAT, released the Announcement of the SAT on Issues Concerning the Recognition of Chinese-Controlled Enterprises Incorporated Overseas as Resident Enterprises on the Basis of Their Actual Management Bodies and supplemented some provisions on the administrative procedures for the recognition of resident enterprise, while the standards used to classify resident enterprises in Circular 82 remain unchanged.

Although BeiGene, Ltd. does not have a PRC enterprise or enterprise group as ourits primary controlling shareholder and is therefore not a Chinese-controlled offshore incorporated enterprise within the meaning of Circular 82, in the absence of guidance specifically applicable to us, we have applied the guidance set forth in Circular 82 to evaluate the tax residence status of BeiGene, Ltd. and its subsidiaries organized outside of the PRC.

We are not aware of any offshore holding company with a corporate structure similar to ours that has been deemed a PRC "resident enterprise"“resident enterprise” by the PRC tax authorities. Accordingly, we do not believe that our company or any of our overseas subsidiaries should be treated as a PRC resident enterprise.

However, the tax resident status of an enterprise is subject to determination by the PRC tax authorities and uncertainties remain with respect to the interpretation of the term "de facto management body." If the PRC tax authorities determine that our Cayman Islands holding company is a resident enterprise for PRC EITenterprise income tax purposes, a number of unfavorable PRC tax consequences could follow and we may be subject to EITenterprise income tax at a rate of 25% on our worldwide taxable income, as well as to PRC EITenterprise income tax reporting obligations. In that case, it is possible that dividends paid to us by our PRC subsidiaries will not be subject to PRC withholding tax.


Dividends payable to our foreign investors may be subject to PRC withholding tax and gains on the sale of the ADSs or ordinary shares by our foreign investors may be subject to PRC tax.

If we are deemed a PRC resident enterprise, as described under "—We may be treated as a resident enterprise for PRC tax purposes under the EIT Law and be subject to PRC tax on our worldwide taxable income at a rate of 25%," dividends paid on our ordinary shares or ADSs, and any gain realized from the transfer of our ordinary shares or ADSs, may be treated as income derived from sources within the PRC. As a result, dividends paid to non-PRC resident enterprise ADS holders or shareholders may be subject to PRC withholding tax at a rate of 10% (or 20% in the case of non-PRC individual ADS holders or shareholders) and gains realized by non-PRC resident enterprises ADS holders or shareholders from the transfer of our ordinary shares or ADSs may be subject to PRC tax at a rate of 10% (or 20% in the case of non-PRC individual ADS holders or shareholders). It is unclear whether if we or any of our subsidiaries established outside China are considered a PRC resident enterprise, holders of the ADSs or ordinary shares would be able to claim the benefit of income tax treaties or agreements entered into between China and other countries or areas. If dividends payable to our non-PRC investors, or gains from the transfer of the ADSs or ordinary shares by such investors are subject to PRC tax, the value of your investment in the ADSs or ordinary shares may decline significantly.

We and our shareholders face uncertainties with respect to indirect transfers of equity interests in PRC resident enterprises or other assets attributed to a PRC establishment of a non-PRC company, or other assets attributable to a PRC establishment of a non-PRC company.

        On February 3, 2015, the SAT issued

Pursuant to the Bulletin on Issues of Enterprise Income Tax and Indirect Transfers of Assets by Non-PRC Resident Enterprises or ("Bulletin 7,7"), which replaced or supplemented certain previous rules underwas amended by the NoticeAnnouncement on Strengthening AdministrationIssues Relating to Withholding at Source of Enterprise Income Tax for Share Transfers by Non-PRC Residenton Non-resident Enterprises or Circular 698, issued by the SAT on December 10, 2009. Pursuant to this Bulletin,("Announcement 37"), an "indirect transfer"“indirect transfer” of "PRC“PRC taxable assets," including equity interests in a PRC resident enterprise, by non-PRC resident enterprises may be recharacterized and treated as a direct transfer of PRC taxable assets, if such arrangement does not have a reasonable commercial purpose and was established for the purpose of avoiding payment of PRC enterprise income tax. As a result, gains derived from such indirect transfer may be subject to PRC enterprise income tax. When determining whether there is a "reasonable“reasonable commercial purpose"purpose” of the transaction arrangement, factors to be taken into consideration include: whether the main value of the equity interest of the relevant offshore enterprise derives from PRC taxable assets; whether the assets of the relevant offshore enterprise mainly consists of direct or indirect investment in Chinathe PRC or if its income mainly derives from China;the PRC; whether the offshore enterprise and its subsidiaries directly or indirectly holding PRC taxable assets have real commercial nature which is evidenced by their actual function and risk exposure; the duration of existence of the business model and organizational structure; the replicability of the transaction by direct transfer of PRC taxable assets; and the tax situation of such indirect transfer and applicable tax treaties or similar arrangements. In respect of an indirect offshore transfer of assets of a PRC establishment, the resulting gain is to be reported on with the enterprise income tax filing of the PRC establishment or place of business being transferred and would consequently be subject to PRC enterprise income tax at a rate of 25%. Where the underlying transfer relates to equity investments in a PRC resident enterprise, which is not related to a PRC establishment or place of business of a non-resident

enterprise, a PRC enterprise income tax at the rate of 10% would apply, subject to available preferential tax treatment under applicable tax treaties or similar arrangements. Late payment of applicable tax will subject the transferor to default interest. Gains derived from the sale of shares by investors through a public stock exchange are not subject to the PRC enterprise income tax pursuant to Bulletin 7 where such shares were acquired in a transaction through a public stock exchange. As such, the sale of the ADSs or ordinary shares on a public stock exchange will not be subject to PRC enterprise income tax pursuant to Bulletin 7. However, the sale of our


ordinary shares or ADSs by a non-PRC resident enterprise outside a public stock exchange may be subject to PRC enterprise income tax under Bulletin 7.

There are uncertainties as to the application of Bulletin 7. Bulletin 7 may be determined by the tax authorities to be applicable to sale of the shares of our offshore subsidiaries or investments where PRC taxable assets are involved. The transferors and transferees may be subject to the tax filing and withholding or tax payment obligation, while our PRC subsidiaries may be requested to assist in the filing. Furthermore, we, our non-resident enterprises and PRC subsidiaries may be required to spend valuable resources to comply with Bulletin 7 or to establish that we and our non-resident enterprises should not be taxed under Bulletin 7, for our previous and future restructuring or disposal of shares of our offshore subsidiaries, which may have a material adverse effect on our financial condition and results of operations.

The PRC tax authorities have the discretion under Bulletin 7 to make adjustments to the taxable capital gains based on the difference between the fair value of the taxable assets transferred and the cost of investment. If the PRC tax authorities make adjustments to the taxable income of the transactions under Circular 698/Announcement 37, or Bulletin 7, our income tax costs associated with such potential acquisitions or disposals will increase, which may have an adverse effect on our financial condition and results of operations.

Restrictions on currency exchange may limit our ability to utilize our revenue effectively.

The PRC government imposes controls on the convertibility of RMB into foreign currencies and, in certain cases, the remittance of currency out of China.the PRC. A portion of our revenue may in the future beis denominated in RMB. Shortages in availability of foreign currency may then restrict the ability of our PRC subsidiaries to remit sufficient foreign currency to our offshore entities for our offshore entities to pay dividends or make other payments or otherwise to satisfy our foreign currency denominated obligations. The RMB is currently convertible under the "current“current account," which includes dividends, trade and service-related foreign exchange transactions, but not under the "capital“capital account," which includes foreign direct investment and loans, including loans we may secure from our onshore subsidiaries. Currently, our PRC subsidiaries which are wholly-foreign owned enterprises, may purchase foreign currency for settlement of "current“current account transactions," including payment of dividends to us, without the approval of SAFE by complying with certain procedural requirements. However, the relevant PRC governmental authorities may limit or eliminate our ability to purchase foreign currencies in the future for current account transactions. Since a portion of our future revenue may beis denominated in RMB, any existing and future restrictions on currency exchange may limit our ability to utilize revenue generated in RMB to fund our business activities outside of the PRC or pay dividends in foreign currencies to our shareholders, including holders of our ordinary shares and the ADSs. Foreign exchange transactions under the capital account remain subject to limitations and require approvals from, or registration with, SAFE and other relevant PRC governmental authorities.authorities or designated banks. This could affect our ability to obtain foreign currency through debt or equity financing for our subsidiaries.

The timing, amount and negatively impactcriteria of government financial incentives are determined within the trading pricesole discretion of the ADSslocal government authorities and couldcannot be predicted with certainty before we actually receive any financial incentive. We generally do not have the ability to influence local governments in making these decisions. Local governments may decide to reduce or eliminate incentives at any time. In addition, some of the government financial incentives are granted on a materialproject basis and subject to the satisfaction of certain conditions, including compliance with the applicable financial incentive agreements and completion of the specific project therein. We cannot guarantee that we will satisfy all relevant conditions, and if we do so we may be deprived of the relevant incentives.

The audit report included in thisour Annual Report on Form 10-K filed with the SEC is prepared by auditors who are not inspected fully by the Public Company Accounting Oversight Board or the PCAOB,(the "PCAOB"), and as such, our shareholdersinvestors are deprived of the benefits of such inspection.

As an auditor of companies that are publicly traded in the United States and a firm registered with the PCAOB, Ernst & Young Hua Ming LLP is required under the laws of the United States to undergo regular inspections by the PCAOB. However,

because we have substantial operations within the PRC, a jurisdiction where the PCAOB is currently unable to conduct inspections without the approval of the Chinese government authorities, our auditor and its audit work is not currently inspected fully by the PCAOB.

Inspections of other auditors conducted by the PCAOB outside Chinathe PRC have at times identified deficiencies in those auditors'auditors’ audit procedures and quality control procedures, which may be addressed as part of the inspection process to improve future audit quality. The lack of PCAOB inspections of audit work undertaken in Chinathe PRC prevents the PCAOB from regularly evaluating our auditor'sauditor’s audits and its quality control procedures. As a result, shareholdersinvestors may be deprived of the benefits of PCAOB inspections and may lose confidence in our reported financial information and procedures and the quality of our financial statements.

As part of a continued regulatory focus in the United States on access to audit and other information currently protected by national law, in particular China’s, in June 2019, a bipartisan group of lawmakers introduced bills in both houses of the U.S. Congress, which if passed, would require the SEC to maintain a list of issuers for which PCAOB is not able to inspect or investigate an auditor report issued by a foreign public accounting firm. The proposed Ensuring Quality Information and Transparency for Abroad-Based Listings on our Exchanges (“EQUITABLE”) Act prescribes increased disclosure requirements for these issuers and, beginning in 2025, the delisting from U.S. national securities exchanges such as the NASDAQ Global Market of issuers included on the SEC’s list for three consecutive years. Enactment of this legislation or other efforts to increase U.S. regulatory access to audit information could cause investor uncertainty for affected issuers, including us, and the market price of our ADSs and ordinary shares could be adversely affected. It is unclear if this proposed legislation will be enacted. Furthermore, there has been recent deliberations within the U.S. government regarding potentially limiting or restricting China-based companies from accessing U.S. capital markets. If any such policies were to materialize, the resulting legislation, if it were to apply to us, would likely have a material adverse impact on our business and the price of our ADSs and ordinary shares.
Proceedings instituted by the SEC against five PRC-based accounting firms, including our independent registered public accounting firm, could result in our financial statements being determined to not be in compliance with the requirements of the Exchange Act.

In December 2012, the SEC brought administrative proceedings against five accounting firms in China, including our independent registered public accounting firm, alleging that they had refused to produce audit work papers and other documents related to certain other PRC-based companies under investigation by the SEC. On January 22, 2014, an initial administrative law decision was issued, censuring these accounting firms and suspending four of these firms from practicing before the SEC for a period of six months. The decision is neither final nor legally effective unless and until reviewed and approved by the SEC. On February 12, 2014, four of these PRC-based accounting firms appealed to the SEC against this decision. In February 2015, each of the four PRC-based accounting firms agreed to a censure and to pay a fine to the SEC to settle the dispute and avoid suspension of their ability to practice before the SEC. These firms'firms’ ability to continue to serve all their respective clients is not affected by the settlement. The settlement requires these firms to follow detailed procedures to seek to provide the SEC with access to Chinese firms'firms’ audit documents via the China Securities Regulatory Commission.Commission (the "CSRC"). If these firms do not follow these procedures, the SEC could impose penalties such as suspensions, or it could restart the administrative proceedings. The settlement did not require these firms to admit to any violation of law and preserves these firms'firms’ legal defenses in the event the administrative proceeding is restarted. In the event that the SEC restarts the administrative proceedings, depending upon the final outcome, listed companies in the United States with major PRC operations may find it difficult or impossible to retain auditors in respect of their operations in the PRC, which could result in financial statements being determined to not be in compliance with the requirements of the Exchange Act, including possible delisting. Moreover, any negative news about the proceedings against these audit firms may cause investor uncertainty regarding PRC-based, United States-listedU.S.-listed companies and the market price of the ADSs and/or ordinary shares may be adversely affected.

If our independent registered public accounting firm was denied, even temporarily, the ability to practice before the SEC and we were unable to timely find another registered public accounting firm to


audit and issue an opinion on our financial statements, our financial statements could be determined not to be in compliance with the requirements of the Exchange Act. Such a determination could ultimately lead to deregistration from the SEC, which would substantially reduce or effectively terminate the trading of the ADSs in the United States. Moreover, any negative news about the proceedings against these audit firms may adversely affect investor confidence in companies with substantial mainland China-based operations listed in the United States. All these would materially and adversely affect the market price of the ADSs and substantially reduce or effectively terminate the trading of the ADSs in the United States.

Risks Related to theOur American Depositary Shares

and Ordinary Shares

The trading prices of theour ordinary shares and/or ADSs are likely tocan be volatile, which could result in substantial losses to you.

        We completed our initial public offering on February 8, 2016, and there has been a public market for the ADSs for only a short period of time.

The trading price of theour ordinary shares and/or ADSs is likely tocan be volatile and could fluctuate widely in response to a variety of factors, many of which are beyond our control. In addition, the performance and fluctuation of the market prices of other companies with business operations located mainly in China that have listed their securities in Hong Kong or the United States may affect the volatility in the price of and trading volumes for theour ordinary shares and/or ADSs. Some of these companies have experienced significant volatility, including significant price declines after their initial public offerings.volatility. The trading performances of these PRC companies'companies’ securities at the time of or after their offerings may affect the overall investor sentiment towards other PRC companies listed in Hong Kong or the United States and consequently may impact the trading performance of theour ordinary shares and/or ADSs.

In addition to market and industry factors, the price and trading volume for theour ordinary shares and/or ADSs may be highly volatile for specific business reasons, including:


        Any of these factors may result in large and sudden changes in the volume and trading price of the ADSs. In the past, following periods of volatility in the market price of a company's securities, shareholders have often instituted securities class action litigation against that company. If we were involved in a class action suit, it could divert the attention of management, and, if adversely determined, have a material adverse effect on our financial condition and results of operations.

environment.

In addition, the stock market, in general, and small pharmaceutical and biotechnology companies, in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors may negatively affect the market price of theour ordinary shares and/or ADSs, regardless of our actual operating performance. Further, the current declinevolatility in the financial markets and related factors beyond our control may cause the ADSsordinary share and/or ADS price to decline rapidly and unexpectedly.

The characteristics of the U.S. capital markets and the Hong Kong capital markets are different.
The Nasdaq and HKEx have different trading hours, trading characteristics (including trading volume and liquidity), trading and listing rules, and investor bases (including different levels of retail and institutional participation). As a result of these differences, the trading prices of our ordinary shares and the ADSs representing them might not be the same, even allowing for currency differences. Fluctuations in the price of our ADSs due to circumstances peculiar to its home capital market could materially and adversely affect the price of the ordinary shares, and vice versa. Because of the different characteristics of the U.S. and Hong Kong equity markets, the historic market prices of our ADSs and ordinary shares may not be indicative of the performance of our securities going forward.
We may be subject to securities litigation, which is expensive and could divert management attention.

        The ADS price may be volatile, and in the past companiesattention.

Companies that have experienced volatility in the volume and market price of their ADSsshares have been subject to an increased incidence of securities class action litigation.litigation, particularly in our industry in recent years. We may be the target of this type of litigation in the future. Securities litigation against us could result in substantial costs and divert our management'smanagement’s attention from other business concerns, whichand, if adversely determined, could seriously harmhave a material adverse effect on our business.

business, financial condition and results of operations.


Future sales of theour ordinary shares and/or ADSs in the public market could cause the ordinary shares and/or ADS price to fall.

The ADS price of our ordinary shares and/or ADSs could decline as a result of sales of a large number of the ordinary shares and/or ADSs or the perception that these sales could occur. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate.

As of March 17, 2017, we had 518,602,349February 14, 2020, 1,007,975,711 ordinary shares, par value $0.0001 per share, were outstanding, of which 251,251,247846,730,482 ordinary shares were held in the form of 19,327,019 American Depositary Shares.

65,133,114 ADSs, each representing 13 ordinary shares.

We filed a registration statement with the SEC on behalf of certain shareholders on May 26, 2017, registering 299,279,370 ordinary shares in the form of 23,021,490 ADSs to be resold by the selling shareholders identified therein and in any related prospectus supplement from time to time. Furthermore, we have registered or willplan to register the offer and sale of all ordinary sharessecurities that we have issued and may issue in the future under our equity compensation plans, including upon the exercise of share options. These ordinary shares canoptions and vesting of restricted share units and under our employee share purchase plan. If these additional securities are sold, or if it is perceived that they will be freely sold, in the public market, upon issuance.

        Asthe trading price of March 17, 2017, the holders of approximately 300,990,453our ordinary shares and/or 58%, of our outstanding ordinary shares, willADSs could decline. We have rights, subject to some conditions, to require us to file registration statements covering the sale of their ordinary shares or to include their ordinary shares in registration statements that we may file for ourselves or other shareholders. Once we register the offer and sale of ordinary shares for the holders ofalso granted certain registration rights they can be freely soldwith respect to the shares issued to BMS in the public market.

event that they are not eligible for sale under Rule 144. Amgen also has specified registration rights upon expiration of the lock-up.

In addition, in the future, we may issue additional ordinary shares, ADSs or other equity or debt securities convertible into ordinary shares or ADSs in connection with a financing, acquisition, license, litigation settlement, employee arrangements or otherwise. Any such issuance could result in substantial dilution to our existing shareholders and could cause the ordinary share and/or ADS price to decline.

We are currently an "emerging growth company." As a result of the reduced disclosure requirements applicable to emerging growth companies, the ADSs may be less attractive to investors.

        We are currently an "emerging growth company," as defined in the JOBS Act. For so long as we remain an emerging growth company, we are permitted and intend to rely on some of the exemptions from certain reporting requirements that are applicable to other public companies that are not emerging growth companies. These exemptions include but are not limited to not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor's report providing additional information about the audit and the financial statements, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

        We cannot predict whether investors will find the ADSs less attractive because we will rely on these exemptions. If some investors find the ADSs less attractive as a result, there may be a less active trading market for the ADSs and the ADS price may be more volatile.

Because we do not expect to pay dividends in the foreseeable future, you must rely on price appreciation of the ordinary shares and/or ADSs for return on your investment.

We intend to retain most, if not all, of our available funds and earnings to fund the development and growth of our business. As a result, we do not expect to pay any cash dividends in the foreseeable future. Therefore, you should not rely on an investment in the ordinary shares and/or ADSs as a source for any future dividend income.

Our board of directors has significant discretion as to whether to distribute dividends. Even if our board of directors decides to declare and pay dividends, the timing, amount and form of future dividends, if any, will depend on, among other things, our future results of operations and cash flow, our capital requirements and surplus, the amount of distributions, if any, received by us from our subsidiaries, our financial condition, contractual and regulatory restrictions and other factors deemed relevant by our board of directors. Accordingly, the return on your investment in the ordinary shares and/or ADSs will likely depend entirely upon any future price appreciation of the ordinary shares and/or ADSs. There is no guarantee that the ordinary shares and/or ADSs will appreciate in value or even maintain the price at which you purchased the ordinary shares and/or ADSs. You may not realize a return on your investment in the ordinary shares and/or ADSs and you may even lose your entire investment in the ordinary shares and/or ADSs.


If securities or industry analysts do not continue to publish research or publish inaccurate or unfavorable research about our business, the market price for the ordinary shares and/or ADSs and trading volume could decline.

The trading market for the ordinary shares and ADSs relies in part on the research and reports that equity research analysts publish about us or our business. We do not control these analysts. If research analysts do not establish and maintain adequate research coverage or if one or more of the analysts who covers us downgrades the ordinary shares and/or ADSs or publishes inaccurate or unfavorable research about our business, the market price for the ordinary shares and/or ADSs would likely decline. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, we could lose visibility in the financial markets, which, in turn, could cause the market price or trading volume for the ordinary shares and/or ADSs to decline significantly.

We are a Cayman Islands company. Because judicial precedent regarding the rights of shareholders is more limited under Cayman Islands law than under Hong Kong law or U.S. law, shareholders may have fewer shareholder rights than they would have under Hong Kong law or U.S. law.

law and may face difficulties in protecting your interests.

We are an exempted company with limited liability incorporated in the Cayman Islands. Our corporate affairs are governed by our amended and restated memorandum and articles of association (as may be further amended from time to time), the Companies Law (as amended) of the Cayman Islands and the common law of the Cayman Islands. The rights of shareholders to take action against the directors, actions by minority shareholders and the fiduciary responsibilities of our directors are to a large extent governed by the common law of the Cayman Islands. This common law is derived in part from comparatively

limited judicial precedent in the Cayman Islands as well as from English common law, which has persuasive, but not binding, authority on a court in the Cayman Islands. The rights of our shareholders and the fiduciary responsibilities of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in some jurisdictions in Hong Kong and the United States. In particular, the Cayman Islands has a less developed body of securities law than Hong Kong or the United States. In addition, some states in the United States, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands.

In addition, as a Cayman Islands exempted company, our shareholders have no general rights under Cayman Islands law to inspect corporate records and accounts or to obtain copies of lists of shareholders of these companies with the exception that the shareholders may request a copy of the current amended and restated memorandum and articles of association. Our directors have discretion under our amended and restated articles of association to determine whether or not, and under what conditions, our corporate records may be inspected by our shareholders, but are not obliged to make them available to our shareholders. This may make it more difficult for you to obtain the information needed to establish any facts necessary for a shareholder motion or to solicit proxies from other shareholders in connection with a proxy contest. As a Cayman Islands company, we may not have standing to initiate a derivative action in a Hong Kong or U.S. federal court of the United States.court. As a result, you may be limited in your ability to protect your interests if you are harmed in a manner that would otherwise enable you to sue in a United States federal court. In addition, shareholders of Cayman Islands companies may not have standing to initiate a shareholder derivative action in Hong Kong or U.S. federal courts.

        As a result of all of the above, public shareholders may have more difficulty in protecting their interests in the face of actions taken by management, members of the board of directors or controlling shareholders than they would as public shareholders of a U.S. company.

You may face difficulties in protecting your interests, and your ability to protect your rights through the U.S. federal courts may be limited because we are incorporated under Cayman Islands law, we currently conduct substantially all of our operations outside the United States and some

Some of our directors and executive officers reside outside the United States.

        We are incorporated in the Cayman Islandsof Hong Kong and currently conduct substantially all of our operations outside the United States through our subsidiaries. Some of our directors and executive


officers reside outside the United States and a substantial portion of their assets are located outside of Hong Kong and the United States. As a result, it may be difficult or impossible for you to bring an action against us or against these individuals in the Cayman IslandsHong Kong or in Chinathe United States in the event that you believe that your rights have been infringed under the securities laws of Hong Kong, the United States or otherwise. To the extent our directors and executive officers reside outside China or their assets are located outside China, it may not be possible for investors to effect service of process upon us or our management inside China. Even if you are successful in bringing an action, of this kind, the laws of the Cayman Islands and China may render you unable to enforce a judgment against our assets or the assets of our directors and officers. There is no statutory recognition in the Cayman Islands of judgments obtained in the United States, Hong Kong or China, although the courts of the Cayman Islands will generally recognize and enforce a non-penal judgment of a foreign court of competent jurisdiction without retrial on the merits.

As a result of the above, public shareholders may have more difficulty protecting their interests in the face of actions taken by management, members of the board of directors or controlling shareholders than they would as public shareholders of a Hong Kong company or a U.S. company.
Your voting rights as a holder of the ADSs are limited by the terms of the deposit agreement, as amended.

agreement. The depositary for the ADSs will give us a discretionary proxy to vote our ordinary shares underlying your ADSs if you do not vote at shareholders’ meetings, except in limited circumstances, which could adversely affect your interests.

You may exercise your voting rights with respect to the ordinary shares underlying your ADSs only in accordance with the provisions of the deposit agreement, as amended.agreement. Upon receipt of voting instructions from you in the manner set forth in the deposit agreement, the depositary for the ADSs will endeavor to vote your underlying ordinary shares in accordance with these instructions. Under our articles of association, the minimum notice period required for convening aan annual general meeting is seventwenty-one calendar days and the minimum notice period required for convening an extraordinary general meeting is fourteen calendar days. When a general meeting is convened, you may not receive sufficient notice of a shareholders'shareholders’ meeting to permit you to withdraw your ordinary shares to allow you to cast your vote with respect to any specific matter at the meeting. In addition, the depositary and its agents may not be able to send voting instructions to you or carry out your voting instructions in a timely manner. We will make all reasonable efforts to cause the depositary to extend voting rights to you in a timely manner, but you may not receive the voting materials in time to ensure that you can instruct the depositary to vote your shares. Furthermore, the depositary and its agents will not be responsible for any failure to carry out any instructions to vote, for the manner in which any vote is cast or for the effect of any such vote. As a result, you may not be able to exercise your right to vote and you may lack recourse if your ordinary shares are not voted as you requested.

Under the deposit agreement, for the ADSs, the depositary will give us a discretionary proxy to vote the ordinary shares underlying your ADSs at shareholders’ meetings if you do not give voting instructions to the depositary, unless:
we have failed to timely provide the depositary with our notice of meeting and related voting materials;
we have instructed the depositary that we do not wish a discretionary proxy to be given;
we have informed the depositary that there is substantial opposition as to a matter to be voted on at the meeting; or

a matter to be voted on at the meeting would have a material adverse impact on shareholders.
The effect of this discretionary proxy is that, if you fail to give voting instructions to the depositary, you cannot prevent the ordinary shares underlying your ADSs from being voted, absent the situations described above, and it may make it more difficult for you to influence our management. Holders of our ordinary shares are not subject to this discretionary proxy.
Anti-takeover provisions in our charterconstitutional documents may discourage our acquisition by a third party, which could limit our shareholders'shareholders’ opportunity to sell their shares including ordinary shares represented by the ADSs, at a premium.

Our amended and restated memorandum and articles of association include provisions that could limit the ability of others to acquire control of our company, could modify our structure or could cause us to engage in change-of-control transactions. These provisions could have the effect of depriving our shareholders of an opportunity to sell their shares, including ordinary shares represented by ADSs, at a premium over prevailing market prices by discouraging third parties from seeking to obtain control in a tender offer or similar transaction.

For example, our board of directors has the authority, without further action by our shareholders, to issue preferred shares in one or more series and to fix the powers and rights of these shares, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences, any or all of which may be greater than the rights associated with our ordinary shares. preferredPreferred shares could thus be issued quickly with terms calculated to delay or prevent a change in control or make removal of management more difficult. In addition, if our board of directors authorizes the issuance of preferred shares, the market price of the ordinary shares and/or ADSs may fall and the voting and other rights of the holders of our ordinary shares and/or ADSs may be materially and adversely affected.

Furthermore, the amended and restated articles of association permit the directors to vary all or any of the rights attaching to any class of shares in issue without the consent of the shareholder but only if such variation is considered by the directors not to have a material adverse effect upon such holder. The directors cannot vary the rights of shares if such variation would have a material adverse effect of


the holder. The amended and restated articles of association provide that the holders must consent to any such material adverse changes in the manner set out therein.

Because our directors are divided into three classes with staggered terms of three years each, shareholders can only elect or remove a limited number of our directors in any given year. The length of these terms could present an obstacle to certain actions, such as a merger or other change of control, which could be in the interest of our shareholders.

Our amended and restated memorandum and articles of association designate courts in the Cayman Islands as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our shareholders, which could limit our shareholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers or other employees.
Our amended and restated memorandum and articles of association provide that, unless we consent in writing to the selection of an alternative forum, the courts of Cayman Islands will be the sole and exclusive forum for any derivative action or proceeding brought on behalf of us, any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of us to us or our shareholders, any action asserting a claim arising pursuant to any provision of the Companies Law of the Cayman Islands as amended from time to time, or the amended and restated memorandum and articles of association, or any action asserting a claim governed by the internal affairs doctrine (as such concept is recognized under the U.S. laws). This provision may limit a shareholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits. Alternatively, if a court were to find this provision of our amended and restated memorandum and articles of association inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions.
Our amended and restated memorandum and articles of association provide that any shareholder bringing an unsuccessful action against us may be obligated to reimburse us for any costs we have incurred in connection with such unsuccessful action.

Our amended and restated memorandum and articles of association provide that under certain circumstances the fees, costs, and expenses that we incur in connection with actions or proceedings brought by any person or entity, which we refer to as claiming parties, may be shifted to such person or entity. If a claiming party asserts any claim; initiates any proceeding; or joins, offers substantial assistance to, or has a direct financial interest in any claim or proceeding against us, (including any proceeding purportedly filed on behalf of us or any shareholder), and such claiming party (oror the third party that received substantial assistance from athe claiming party or in whosewhole claim or proceeding suchthe claiming party hashad a direct financial interest)interest is unsuccessful in obtaining a judgment on the merits in which the claiming party prevails, then such claiming party may, toshall (to the fullest extent permissiblepermitted by law,law) be obligated jointly and severally to reimburse us for all fees, costs, and expenses,

including but not limited to all reasonable attorneys'attorneys’ fees and other litigation expenses, that we may incur in connection with such claim suit, action, or proceeding.

Fee-shifting articles are relatively new and untested in both the Cayman Islands, and the United States.States and Hong Kong. The case law and potential legislative action on fee-shifting articles are evolving and there exists considerable uncertainty regarding the validity of, and potential judicial and legislative responses to, such articles. For example, it is unclear whether our ability to invokeThe application of our fee-shifting article in connection with claims under the federalCayman Islands, the United States or Hong Kong securities laws, including claims related to any of our public offerings, would be preempted by federal law. Similarly, it is unclear how courts might apply the standard that a claiming party must obtain a judgment that substantially achieves, in substance and amount, the full remedy sought. The application of our fee-shifting article in connection with such claims, if any, will depend in part on future developments of the law. We cannot assure you that we will or will not invoke our fee-shifting article in any particular dispute, including any claims related to our public offerings.dispute. Consistent with our directors'directors’ fiduciary duties to act in the best interests of the company,Company, the directors may in their sole discretion from time to time decide whether or not to enforce this article. In addition, given the unsettled state of the law related to fee-shifting articles, such as ours, we may incur significant additional costs associated with resolving disputes with respect to such articles, which could adversely affect our business and financial condition.

If a shareholder that brings any such claim suit, action or proceeding is unable to obtain the judgment sought, the attorneys'attorneys’ fees and other litigation expenses that might be shifted to a claiming party are potentiallymay be significant. This fee-shifting article, therefore, may dissuade or discourage current or former shareholders (and their attorneys) from initiating lawsuits or claims against us. In addition, it may impact the fees, contingency or otherwise, required by potential plaintiffs'plaintiffs’ attorneys to represent our shareholders or otherwise discourage plaintiffs'plaintiffs’ attorneys from representing our shareholders at all. As a result, this article may limit the ability of shareholders to affect the management and direction of our company, particularly through litigation or the threat of litigation.


The depositary for the ADSs will give us a discretionary proxy to vote our ordinary shares underlying your ADSs if you do not vote at shareholders' meetings, except in limited circumstances, which could adversely affect your interests.

        Under the deposit agreement, as amended, for the ADSs, the depositary will give us a discretionary proxy to vote our ordinary shares underlying your ADSs at shareholders' meetings if you do not give voting instructions to the depositary, unless:

        The effect of this discretionary proxy is that, if you fail to give voting instructions to the depositary, you cannot prevent our ordinary shares underlying your ADSs from being voted, absent the situations described above, and it may make it more difficult for shareholders to influence our management. Holders of our ordinary shares are not subject to this discretionary proxy.

Holders of the ADSs may be subject to limitations on transfer of their ADSs.

Your ADSs are transferable on the books of the depositary. However, the depositary may close its books at any time or from time to time when it deems expedient in connection with the performance of its duties. The depositary may refuse to deliver, transfer or register transfers of your ADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary think it is advisable to do so because of any requirement of law, government or governmental body, or under any provision of the deposit agreement, as amended, or for any other reason, subject to your right to cancel your ADSs and withdraw the underlying ordinary shares. Temporary delays in the cancellation of your ADSs and withdrawal of the underlying common shares may arise because the depositary has closed its transfer books or we have closed our transfer books, the transfer of ordinary shares is blocked to permit voting at a shareholders'shareholders’ meeting or we are paying a dividend on our ordinary shares.

In addition, you may not be able to cancel your ADSs and withdraw the underlying ordinary shares when you owe money for fees, taxes and similar charges and when it is necessary to prohibit withdrawals in order to comply with any laws or governmental regulations that apply to ADSs or to the withdrawal of ordinary shares or other deposited securities.

The depositary for the ADSs is entitled to charge holders fees for various services, including annual service fees.

Dealings in the ordinary shares registered in our Hong Kong register of members will be subject to Hong Kong stamp duty.

The depositary for the ADSs is entitled to charge holders fees for various services including for the issuance of ADSs upon deposit of ordinary shares, cancellation of ADSs, distributions of cash dividends or other cash distributions, distributions of ADSs pursuant to share dividends or other free share distributions, distributions of securities other than ADSs and annual service fees. In the case of ADSs issued by the depositary into The Depository Trust Company or DTC,("DTC"), the fees will be charged by the DTC participant to the account of the applicable beneficial owner in accordance with the procedures and practices of the DTC participant as in effect at the time.

Additionally, dealings in the ordinary shares registered in our Hong Kong register of members will be subject to Hong Kong stamp duty.

YouHolders of the ADSs may not receive distributions on our ordinary shares or any value for them if it is illegal or impractical to make them available to you.

The depositary of the ADSs has agreed to pay you the cash dividends or other distributions it or the custodian for the ADSs receives on our ordinary shares or other deposited securities after deducting its fees and expenses. You will receive these distributions in proportion to the number of our ordinary shares that your ADSs represent. However, the depositary is not responsible for making such payments or distributions if it is unlawful or impractical to make a distribution available to any holders of ADSs. For example, it would be unlawful to make a distribution to a holder of ADSs if it consists of securities that require registration under the Securities Act of 1933, as amended (the "Securities Act"), but that are not properly registered or distributed pursuant to an applicable exemption from registration. The depositary is not responsible for making a distribution available to any holders of ADSs if any government approval or registration required for such distribution cannot be obtained after reasonable efforts made by the depositary. We have no obligation to take any other action to permit the distribution of the ADSs, ordinary shares, rights or anything else to holders of the ADSs. This means that you may not receive the distributions we

make on our ordinary shares or any value for them if it is illegal or impractical for us to make them available to you. These restrictions may materially reduce the value of your ADSs.

Holders of the ADSs may not be able to participate in rights offerings and may experience dilution of their holdings.

From time to time, we may distribute rights to our shareholders, including rights to acquire securities. Under the deposit agreement, the depositary will not distribute rights to holders of ADSs unless the distribution and sale of rights and the securities to which these rights relate are either exempt from registration under the Securities Act with respect to all holders of ADSs or are registered under the provisions of the Securities Act. The depositary may, but is not required to, attempt to sell these undistributed rights to third parties and may allow the rights to lapse. We may be unable to establish an exemption from registration under the Securities Act, and we are under no obligation to file a registration statement with respect to these rights or underlying securities or to try to have a registration statement declared effective. Accordingly, holders of ADSs may be unable to participate in our rights offerings and may experience dilution of their holdings as a result.

Our corporate actions are substantially controlled by our directors, executive officers and other principal shareholders, who can exert significant influence over important corporate matters, which may reduce the price of the ordinary shares and/or ADSs and deprive you of an opportunity to receive a premium for your ordinary shares and/or ADSs.

Our directors, executive officers and principal shareholders beneficially owned approximately 69.8%68% of our outstanding ordinary shares as of March 17, 2017.February 14, 2020. These shareholders, if acting together, could exert substantial influence over matters such as electing directors and approving material mergers, acquisitions or other business combination transactions. This concentration of ownership may also discourage, delay or prevent a change in control of our company, which could have the dual effect of depriving our shareholders of an opportunity to receive a premium for their shares as part of a sale of our company and reducing the price of theour ordinary shares and/or ADSs. These actions may be taken even if they are opposed by our other shareholders, including the holders of the ADSs.shareholders. In addition, these persons could divert business opportunities away from us to themselves or others.

We have incurred increased costs as a result of operating as a public company, and our management will be required to devote substantial time to new compliance initiatives and corporate governance practices.

        As a public company, we have incurred and will continue to incur significant legal, accounting and other expenses that we did not incur as a private company. For example, as a public company, we are now subject to the reporting requirements of the Exchange Act, which requires, among other things, that we file with the SEC annual, quarterly and current reports with respect to our business and


financial condition. We have incurred and will continue to incur costs associated with the preparation and filing of these reports. The Sarbanes-Oxley Act of 2002, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing requirements of the NASDAQ Stock Market and other applicable securities rules and regulations impose various requirements on public companies, including establishment and maintenance of effective disclosure and financial controls and corporate governance practices. Our management and other personnel will need to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations will increase our legal and financial compliance costs and will make some activities more time-consuming and costly. For example, we expect that these rules and regulations may make it more difficult and more expensive for us to obtain director and officer liability insurance, which in turn could make it more difficult for us to attract and retain qualified members of our board of directors.

        We continue to evaluate these rules and regulations, and cannot predict or estimate the amount of additional costs we may incur or the timing of such costs. These rules and regulations are often subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices.

        Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, we will first be required to furnish a report by our management on our internal control over financial reporting for the year ending December 31, 2016. However, while we remain an emerging growth company, we will not be required to include an attestation report on internal control over financial reporting issued by our independent registered public accounting firm. To achieve compliance with Section 404 within the prescribed period, we will continue to be engaged in a process to document and evaluate our internal control over financial reporting, which is both costly and challenging. In this regard, we will need to continue to dedicate internal resources, potentially engage outside consultants and adopt a detailed work plan to assess and document the adequacy of internal control over financial reporting, continue steps to improve control processes as appropriate, validate through testing that controls are functioning as documented and implement a continuous reporting and improvement process for internal control over financial reporting. Despite our efforts, there is a risk that we will not be able to conclude, within the prescribed timeframe or at all, that our internal control over financial reporting is effective as required by Section 404. If we identify one or more material weaknesses, it could result in an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements.

We may be a "passivepassive foreign investment company" in future taxable years, which may have adverse U.S. federal income tax consequences for U.S. shareholders.

A non-U.S. corporation will be classified as a “passive foreign investment company” (“PFIC”) for any taxable year if either (1) 75% or more of its gross income consists of certain types of passive income or (2) 50% or more of the average quarterly value of its assets during such year produce or are held for the production of passive income. Based upon the current and expected composition of our income and assets, we do not presently expect to be a PFIC for the current taxable year. Nevertheless, because our PFIC status must be determined annually with respect to each taxable year and will depend on the composition and character of our assets and income, and the value of our assets (which may be determined, in part, by reference to the market value of our ADSs and ordinary shares, which may be volatile) over the course of such taxable year, we may be a PFIC in any taxable year. If we determine not to deploy significant amounts of cash for active purposes, our risk of being a PFIC may substantially increase. Because there are uncertainties in the application of the relevant rules and PFIC status is a factual determination made annually after the close of each taxable year, there can be no assurance that we will not be a PFIC for the current taxable year or any future taxable year.  In addition, it is possible that the Internal Revenue Service may challenge our classification of certain income and assets as non-passive, which may result in our being or becoming a PFIC in the current or subsequent years. Further, U.S. investors should be aware that based on current business plans and financial expectations (including thatwe determined we were a substantial percentage of our assets are held in cash and cash equivalents), we expect that we may be a passive foreign investment company within the meaning of Section 1297 of the Internal Revenue Code of 1986, as amended, or PFIC for the current taxable year and in future taxable years. 2016.
If we are a PFIC for any taxable year during a U.S. shareholder'sshareholder’s holding period of the ADSsordinary shares or ordinary shares,ADSs, then such U.S. shareholder generally will be required to treat anymay incur significantly increased United States income tax on gain realized upon arecognized on the sale or other disposition of the ADSs or ordinary shares or any "excess distribution" receivedADSs and on the ADSs orreceipt of distributions on the ordinary shares as ordinary income earned over the U.S. shareholder's holding period for theor ADSs or ordinary shares, and to pay the applicable taxes on such ordinary income along with an interest charge at the rate applicable to underpayments of tax on a portion of the resulting tax liability, unless the shareholder makes a timely and effective "qualified electing fund" election, or QEF election, or "mark-to-market" election with respect to the ADSs or ordinary shares. A U.S. shareholder who makesextent such distribution is treated as an effective QEF election generally must report on a current basis its share of our net capital


gain and ordinary earnings for any taxable year in which we are a PFIC, whether or not we distribute any amounts to our shareholders. If a QEF election is not in effect for“excess distribution” under the first taxable year in your holding period in which we are a PFIC, a QEF election can only be made if you elect to recognize gain as if you had sold the ADSs or ordinary shares for their fair market value on the first day of your taxable year in which the PFIC becomes a QEF pursuant to the QEF election. The gain recognized on this deemed sale wouldUnited States federal income tax rules. In addition, such holders may be subject to the general tax treatment of PFICs discussed above. We intend to determine our PFIC status at the end of each taxable year and to satisfy any applicable record keeping andburdensome reporting requirements that apply to a QEF, and will endeavor to provide to you, for each taxable year that we determinerequirements.

Further, if we are or may beclassified as a PFIC the information that is necessary for you to makeany year during which a QEF election with respect to us (and any ofU.S. shareholder holds our subsidiaries which are lower-tier PFICs).

If you are a "Ten“Ten Percent Shareholder," you may be subject to adverse U.S. federal income tax consequences if we are classified as a Controlled Foreign Corporation.

Each "Ten“Ten Percent Shareholder"Shareholder” (as defined below) in a non-U.S. corporation that is classified as a "controlled“controlled foreign corporation," or a CFC, for U.S. federal income tax purposes is generally is required to include in income for U.S. federal tax purposes such Ten Percent Shareholder'sShareholder’s pro rata share of the "CFC's" "SubpartCFC’s “Subpart F income"income” and investment of earnings in U.S. property, even if the CFC has made no distributions to its shareholders. Each Ten Percent Shareholder is also required to

include in gross income its “global intangible low-taxed income,” which is determined by reference to the income of CFCs of which such Ten Percent Shareholder is a Ten Percent Shareholder. Ten Percent Shareholders that are corporations may be entitled to a deduction equal to the foreign portion of any dividend when a dividend is paid. A non-U.S. corporation will generally will be classified as a CFC for U.S federal income tax purposes if Ten Percent Shareholders own in the aggregate, directly or indirectly, more than 50% of either the total combined voting power of all classes of stock of such corporation entitled to vote or of the total value of the stock of such corporation. A "Ten“Ten Percent Shareholder"Shareholder” is a U.S. person (as defined by the Internal Revenue Code of 1986, as amended), who owns or is considered to own 10% or more of the total combined voting power of all classes of stock entitled to vote of such corporation or 10% of the value of all classes of stock of such corporation. The determination of CFC status is complex and includes attribution rules, the application of which is not entirely certain. We may currently beAlthough we believe we are not a CFC and/ornow, we may become one or own interests in one in the future. Holders are urged to consult their own tax advisors with respect to our potential CFC status and the consequences thereof.

We may be subject to adverse legislative or regulatory tax changes that could negatively affect our financial condition.

        The rules dealing with U.S. federal, state and local income taxation are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Treasury Department. Changes to tax laws (which changes may have retroactive application) could adversely affect our stockholders or us. In recent years, many changes have been made and changes are likely to continue to be made in the future. We cannot predict whether, when, in what form, or with what effective dates, tax laws, regulations and rulings may be enacted, promulgated or decided that could result in an increase in our, or our stockholders', tax liability or require changes in the manner in which we operate in order to minimize increases in our tax liability.

Taxation

Cayman Islands Taxation

The Cayman Islands currently levies no taxes on individuals or corporations based upon profits, income, gains or appreciation and there is no taxation in the nature of inheritance tax or estate duty or withholding tax applicable to us or to any holder of the ADSs and ordinary shares. There are no other taxes likely to be material to us levied by the Government of the Cayman Islands except for stamp duties which may be applicable on instruments executed in, or after execution brought within, the jurisdiction of the Cayman Islands. No stamp duty is payable in the Cayman Islands on the issue of shares by, or any transfers of shares of, Cayman Islands companies (except those which hold interests in land in the Cayman Islands). The Cayman Islands is not party to any double tax treaties that are applicable to any payments made to or by our company. There are no exchange control regulations or currency restrictions in the Cayman Islands.

Payments of dividends and capital in respect of the ADSs and ordinary shares will not be subject to taxation in the Cayman Islands and no withholding will be required on the payment of a dividend or capital to any holder of the ADSs or ordinary shares, as the case may be, nor will gains derived from the disposal of the ADSs or ordinary shares be subject to Cayman Islands income or corporation tax.

People's Republic of China

PRC Taxation

Under the Enterprise Income Tax Law, or EIT Law, an enterprise established outside of Chinathe PRC with a "de“de facto management body"body” within Chinathe PRC is considered a "resident“resident enterprise," which means that it is treated in a manner similar to a Chinese enterprise for PRC enterprise income tax purposes. Although theThe implementation rules of the EIT Law define "de“de facto management body"body” as a managing body that exercises substantivesubstantial and overall management and control over the production and business,operations, personnel, accounting books and assetsproperties of an enterprise, the only official guidance for this definition currently available is set forth inenterprise. In addition, the Notice Regarding the Determination of Chinese-ControlledChinese‑Controlled Offshore Incorporated Enterprise as PRC Tax Resident Enterprises on the Basis of De Facto Management Bodies, or Circular 82, issued by the State Administration of Taxation, which provides guidance on the determination of the tax residence status of a Chinese‑controlled offshore incorporated enterprise, defines Chinese-controlled offshore incorporated enterprise defined as an enterprise that is incorporated under the laws of a foreign country or territory and that has a PRC enterprise or enterprise group as its primary controlling shareholder. Although BeiGene, Ltd. does not have a PRC enterprise or enterprise group as our primary controlling shareholder and is therefore not a Chinese-controlledChinese‑controlled offshore incorporated enterprise within the meaning of Circular 82, in the absence of guidance specifically applicable to us, we have applied the guidance set forth in Circular 82 to evaluate the tax residence status of BeiGene, Ltd. and its subsidiaries organized outside the PRC.

According to Circular 82, a Chinese-controlledChinese‑controlled offshore incorporated enterprise will be regarded as a PRC tax resident by virtue of having a "de“de facto management body"body” in China and will be subject to PRC enterprise income tax on its worldwide income only if all of the following criteria are met:

the primary location of the enterprise'senterprise’s senior executives of the day-to-dayday‑to‑day operational management and senior management departments performing their duties is in the PRC;

decisions relating to the enterprise'senterprise’s financial and human resource matters are made or are subject to approval by organizations or personnel in the PRC;

Currently, some of the members of our management team are located in China. However, we do not believe that we meet all of the conditions outlined in the immediately preceding paragraph. BeiGene, Ltd. and its offshore subsidiaries are incorporated outside the PRC. As a holding company, our key assets and records, including the resolutions and meeting minutes of our board of directors and the resolutions and meeting minutes of our shareholders, are located and maintained outside the PRC. However, weWe are not aware of any offshore holding companies with a corporate structure similar to ours that has been deemed a PRC "resident enterprise"“resident enterprise” by the PRC tax authorities. Accordingly, we believe that BeiGene, Ltd. and its offshore subsidiaries should not be treated as a "resident enterprise"“resident enterprise” for PRC tax purposes if the criteria for "de“de facto management body"body” as set forth in Circular 82 were deemed applicable to us. However, as the tax residency status of an enterprise is subject to determination by the PRC tax authorities and uncertainties remain with respect to the interpretation of the term "de“de facto management body"body” as applicable to our offshore entities, we will continue to monitor our tax status.

The implementation rules of the EIT Law provide that, (1) if the enterprise that distributes dividends is domiciled in the PRC or (2) if gains are realized from transferring equity interests of enterprises domiciled in the PRC, then such dividends or

capital gains are treated as China-sourcedChina‑sourced income. It is not clear how "domicile"“domicile” may be interpreted under the EIT Law, and it may be interpreted as the jurisdiction where the enterprise is a tax resident. Therefore, if we are considered as a PRC tax resident enterprise for PRC tax purposes, any dividends we pay to our overseas shareholders or ADS holders as well as gains realized by such shareholders or ADS holders from the transfer of our shares or ADSs may be regarded as China-sourcedChina‑sourced income. As a result, dividends paid to non-PRCnon‑PRC resident enterprise ADS holders or shareholders may be subject to PRC withholding tax at a rate of up to 10% (or 20% in the case of non-PRCnon‑PRC individual ADS holders or shareholders) and gains realized by non-PRCnon‑PRC resident enterprise ADS holders or shareholders from the transfer of our ordinary shares or ADSs may be subject to PRC tax at a rate of 10% (or 20% in the case of non-PRCnon‑PRC individual ADS holders or shareholders). It is also unclear whether, if we are considered a PRC resident enterprise, holders of our shares or ADSs would be able to claim the benefit of income tax treaties or agreements entered into between China and other countries or areas.

Item 7. Management'sManagement’s Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion and analysis of our financial condition and results of operations together with "Item“Item 6—Selected Consolidated Financial Data"Data” and our consolidated financial statements and related notes appearing elsewhere in this Annual Report. In addition to historical information, this discussion and analysis contains forward-lookingforward‑looking statements that involve risks, uncertainties and assumptions. Our actual results may differ materially from those anticipated in these forward-lookingforward‑looking statements as a result of certain factors. We discuss factors that we believe could cause or contribute to these differences below and elsewhere in this report, including those set forth under "Part“Part I—Item 1A—Risk Factors"Factors” and under "Forward-Looking“Forward‑Looking Statements and Market Data"Data” in this Annual Report.

Information pertaining to fiscal year 2017 was included in our Annual Report on Form 10-K for the year ended December 31, 2018 beginning on page 94 under Part II, Item 7, “Management’s Discussion and Analysis of Financial Position and Results of Operations,” which was filed with the SEC on February 28, 2019.
Overview

We are a globallyglobal commercial-stage biotechnology company focused clinical-stage biopharmaceuticalon developing and commercializing innovative molecularly-targeted and immuno-oncology cancer therapeutics. We started as a research and development company dedicated to becomingin Beijing in 2010. Over the last ten years, we have developed into a leaderfully-integrated global biotechnology company, with significant commercial, manufacturing, and research and development capabilities.
We have built substantial commercial capabilities in China and the United States, and are currently marketing two internally-developed drugs and three in-licensed drugs. We also anticipate introducing five more in-licensed drugs into the China market in the discoverynext one to two years. In the United States, we market BRUKINSA (zanubrutinib) for adult patients with mantle cell lymphoma ("MCL") who have received at least one prior therapy and in China, we have received marketing approval and are in the process of launching tislelizumab for patients with classical Hodgkin’s Lymphoma ("cHL") who have received at least two prior therapies. We have filed four additional supplementary new drug applications ("sNDA") for regulatory approvals in China and are planning for launches in these additional indications in 2020. Our in-licensed portfolio includes ABRAXANE®, REVLIMID® and VIDAZA®, which we have been marketing in China since 2017 under a license from Celgene Logistics Sàrl, a Bristol-Myers Squibb company (“BMS”). We plan on launching additional in-licensed products in China from our collaborations, including XGEVA® (denosumab), KYPROLIS® (carfilzomib) and BLINCYTO® (blinatumomab) from Amgen Inc. ("Amgen"), and SYLVANT® (siltuximab) and QARZIBA® (dinutuximab beta), from EUSA Pharma ("EUSA").
We have built deep clinical development capabilities, including a more than 1,100-person global clinical development team that is running over 60 ongoing or planned clinical trials that have enrolled over 7,500 patients and healthy subjects. We are conducting late-stage clinical trials of BRUKINSA and tislelizumab, including 26 registration or registration-enabling trials in 15 discrete cancer indications. Our internal research capabilities have yielded another late-stage asset, pamiparib, and five other internally-developed drug candidates are currently in early-stage clinical development. In addition, we have been able to leverage our capabilities and China’s rising importance as a clinical science center to expand our clinical and pre-clinical portfolio with in-licensed drug candidates. We are also working with high-quality contract manufacturing organizations ("CMOs") to manufacture our internally-developed commercial and clinical products in China and globally and have built state-of-the-art small molecule and biologic manufacturing facilities in China to support the launches and potential future demand of our internally-developed products.
Based on the strength of our China-inclusive global development and commercial capabilities, we have entered into collaborations with leading pharmaceutical and biotechnology companies to develop and commercialize innovative medicines in China and the Asia-Pacific region. In October 2019, we entered into a strategic collaboration with Amgen pursuant to which we have agreed to collaborate on the commercialization of Amgen’s oncology products XGEVA, KYPROLIS and BLINCYTO in China, and the global development and future commercialization in China of up to 20 of Amgen's clinical- and late pre-clinical-stage pipeline products, including AMG 510, Amgen’s first-in-class investigational KRAS G12C inhibitor.
Recent Developments
On January 13, 2020, we entered into an exclusive development and commercialization agreement for the orphan biologic products SYLVANT and QARZIBA in Greater China with EUSA Pharma ("EUSA"). Under the terms of the agreement, EUSA has granted us exclusive rights to SYLVANT in Greater China and to QARZIBA in mainland China. Under the agreement, we have agreed to fund and undertake all clinical development and regulatory submissions in the territories, and plan to launch and commercialize both products once approved. EUSA received a $40 million upfront payment and will be eligible to receive payments upon the achievement of regulatory and commercial milestones up to a total of $160 million. EUSA will also be eligible to receive tiered royalties on future product sales.

On January 2, 2020, following approval by our shareholders and satisfaction of other closing conditions, we announced the closing of our global strategic oncology collaboration with Amgen for the commercialization and development in China of innovative, molecularly targetedAmgen’s XGEVA, KYPROLIS, and immuno-oncology drugsBLINCYTO, and the joint global development of 20 oncology assets in Amgen’s pipeline, with BeiGene responsible for development and commercialization in China. In connection with the collaboration, Amgen purchased a 20.5% stake in BeiGene for approximately $2.8 billion in cash at $174.85 per American Depositary Share ("ADS").
On December 27, 2019, we announced that our anti-PD-1 antibody tislelizumab received approval from the China National Medical Products Administration ("NMPA") as a treatment for patients with cHL who have received at least two prior therapies. The new drug application ("NDA") was previously granted priority review by the NMPA.
On December 22, 2019, we announced that the NMPA accepted a supplemental new drug application (sNDA) for REVLIMID (lenalidomide), in combination with rituximab, for the treatment of cancer. patients with relapsed or refractory indolent lymphoma (follicular lymphoma or marginal zone lymphoma).
On November 14, 2019, we announced that BRUKINSA received accelerated approval from the United States Food and Drug Administration (FDA) as a treatment for MCL in adult patients who have received at least one prior therapy.
Coronavirus Disease 2019 (COVID-19)
We believeexpect that the next generationworldwide health crisis of cancer treatmentthe coronavirus disease (COVID-19) will utilize therapeutics both as monotherapieshave a negative impact on our operations in China, including clinical trial recruitment and participation, regulatory interactions and inspections, and commercial revenue, particularly in combinationthe first quarter of 2020 and possibly longer depending on the scope and duration of the disruption. We continue to attack multiple underlying mechanismsexecute on our clinical development, regulatory and commercialization goals in China and are working to minimize delays and disruptions.
Components of cancer cell growth and survival. Operating Results
Revenue
We further believe that discovery of next generationbegan generating product revenue in September 2017 through our in-license agreement with BMS to distribute the approved cancer therapies requires new research tools. To that end,ABRAXANE, REVLIMID and VIDAZA in China. Following FDA approval on November 14, 2019, we havelaunched our first internally developed a proprietary cancer biology platform that addressesdrug, BRUKINSA, in the importance of tumor-immune system interactions and the value of primary biopsies in developing new models to support our drug discovery effort. Our strategy is to develop a pipeline of drug candidates with the potential to be best-in-class monotherapies and also important components of multiple-agent combination regimens.

        We have used our cancer biology platform to develop four clinical-stage drug candidates that we believe have the potential to be best-in-class or first-in-class. In addition, we believe that each has the potential to be an important component of a drug combination addressing major unmet medical needs. Our clinical-stage drug candidates include three molecularly targeted agents, BGB-3111, BGB-290 and BGB-283 and one immuno-oncology agent, BGB-A317. BGB-3111United States. Revenues from product sales are recognized when there is a potenttransfer of control from the Company to the customer. The Company determines transfer of control based on when the product is delivered, and highly selective small molecule inhibitortitle passes to the customer. Revenues from product sales are recognized net of BTK. BGB-290 is a molecularly targeted, orally available, potentvariable consideration resulting from rebates, chargebacks, trade discounts and highly selective inhibitor of PARP1allowances, sales returns allowances and PARP2. BGB-283 is a small molecule inhibitor of both the monomer and dimer forms of the RAF kinase. For each of our molecularly targeted drug candidates, we have achieved proof-of-concept by demonstrating objective responsesother incentives. Provisions for estimated reductions to revenue are provided for in the defined patient populations. BGB-3111 received orphan drug designation fromsame period the FDA, for CLL, MCL and WM. Our clinical-stage immuno-oncology agent, BGB-A317, is an investigational humanized monoclonal antibody against the immune checkpoint receptor, PD-1. We have IND Applications in effect for our BTK, PD-1 and PARP inhibitors with the FDA. We have also received approval of our Clinical Trial Applications for each of our four clinical-stage drug candidates from the CFDA. In addition to our clinical-stage drug candidates, we have a robust pipeline of preclinical programsrelated sales are recorded and are planning to advance one or more of these programs into the clinic in the next 12 months.based on contractual terms, historical experience and trend analysis. We retain full global rights for all of our clinical and preclinical drug candidates and programs.

        Since our inception on October 28, 2010, our operations have focused on organizing and staffing our company, business planning, raising capital, establishing our intellectual property portfolio and conducting preclinical studies and clinical trials. We do not have any drug candidates approved for sale and have not generated anyexpect revenue from product sales. We have financed operations through a combination of publicsales to increase in 2020 as we launch our internally developed drugs, BRUKINSA and private equitytislelizumab, and debt financings and public and private grants and contracts, including the net proceedslaunch additional in-licensed products from our initial public offeringcollaborations with Amgen and follow-on public offering,EUSA and continue to expand our efforts to promote our existing commercial products.

In January 2020, we were notified that our tender offer for ABRAXANE was one of the net proceedswinning tenders in China’s centralized procurement process, with a reduction from the issuancecurrent pricing, which is expected to take effect in the second quarter of 2020. Once ABRAXANE is included in the centralized procurement process, we anticipate that demand will increase significantly, although at a senior notesignificantly lower price than we have been charging during 2019 and convertible promissory noteinto 2020, which could have a material impact on our commercialization efforts and results of operations.
To date, we have also recorded revenue from our 2017 collaboration and license agreement with BMS for tislelizumab, which was terminated in June 2019. Under this agreement, we received an upfront payment related to Merck Sharp & Dohme Research GmbH, or MSD, an affiliatethe license fee, which was recognized upon the delivery of Merck Sharp & Dohme Corp., the private placementslicense right. Additionally, the portion of our Series A preferred sharesthe upfront payment related to the reimbursement of undelivered research and Series A-2 preferred shares,development services was deferred and ourrecognized over the performance period of the collaboration arrangement. We recognized the remainder of the deferred research and development services revenue balance upon termination of the collaboration agreement. We also received research and development reimbursement revenue for the basket study trials that BMS opted into through the termination of the collaboration agreement. Pursuant to the terms of the termination agreement, we received a one-time payment of $150 million in June 2019. The entire payment was recognized in the period the termination occurred, as we had no further performance obligations under the collaboration. We also recognized revenue for upfront license fees and milestone payments from a prior collaboration agreement with Merck KGaA, Darmstadt Germany or Merck KGaA, Darmstadt Germany Collaboration. On February 8, 2016 and November 23, 2016, we completed our initial public offering and follow-on public


offering, and received net proceeds of $166.2 million and $198.6 million, respectively, after deducting underwriting discounts and offering expenses. Although it is difficult to predict our liquidity requirements, based upon our current operating plan and the successful completion of our initial public offering and follow-on public offerings, we believe we have sufficient cash to meet our projected operating requirements for at least the next 12 months. See "—Liquidity and Capital Resources."

        Since inception we have incurred significant operating losses. Our net losses were $119.2 million, $57.1 million and $18.5 million forduring the years ended December 31, 2016, 20152017 and 2014,2018, respectively. As

We expect to continue to incur significant expenses and operating losses forbeen sold during the foreseeable future. We anticipate that our expenses will increase significantly in connection with our ongoing activities, as we:

    continue investment in our cancer biology platform;

    continue preclinical and clinical development of our programs;

    continue investment in our manufacturing facilities;

    hire additional research, development and business personnel;

    maintain, expand and protect our intellectual property portfolio; and

    incur additional costs associated with operating as a public company.

        We expect that any revenue we generate will fluctuate from quarter to quarter and year to year as a result of the timing and amount of license fees, milestones, reimbursement of costs incurred and other payments and product sales, to the extent any are successfully commercialized. If we fail to complete the development of our drug candidates in a timely manner or obtain regulatory approval of them, our ability to generate future revenue, and our results of operations and financial position, would be materially adversely affected.

        Cash used in operations were $89.5 million, $39.8 million and $8.7 million, respectively, for years ended December 31, 2016, 2015 and 2014. As of December 31, 2016, we had cash, cash equivalents and short-term investments of $368.2 million, compared with $100.5 million as of December 31, 2015.

period. To date, our revenuecost of sales has consisted of upfront license fees, reimbursed researchthe cost of products purchased from BMS and development expenses and milestone payments from our collaboration agreements with Merck KGaA, Darmstadt Germany on BGB-283 and BGB-290. We have not generated any revenue from product sales and do not expect to generate any revenue from product sales fordistributed in the foreseeable future.

        On May 24, 2013, we entered into license agreements with Merck KGaA, Darmstadt Germany on BGB-283, which we amended and restated on December 10, 2013, and further amended on October 1, 2015 and December 3, 2015. In the latest amendment, Merck KGaA, Darmstadt Germany granted us an exclusive license under certain of its intellectual property rights to develop, manufacture and commercialize the RAF dimer inhibitor in The People's Republic of China which we refer("PRC" or "China"). Costs to as the PRC Territory, subject to certain non-compete restrictions. In March 2017, Merck KGaA, Darmstadt Germany informed us that it will not exercise the Continuation Optionmanufacture inventory in the ex-PRC Territory, and thus, the ex-PRC BRAF Agreement has terminated in its entirety, exceptpreparation for certain provisions that will survive the termination. Under these agreements, we received $13 million in non-refundable payments in 2013 following their execution, $5 million in milestone payments in 2014 and $4 million in milestone


payments in 2015. We are eligible to receive $14 million in payments upon the successful achievement of pre-specified clinical milestones in the PRC Territory. In consideration for the licenses Merck KGaA, Darmstadt Germany grants to us, we were required to pay Merck KGaA, Darmstadt Germany a high single-digit royalty on aggregate net sales of licensed BRAF inhibitors in the PRC Territory.

        On October 28, 2013, we entered into license agreements with Merck KGaA, Darmstadt Germany on BGB-290, pursuant to which (1) we granted to Merck KGaA, Darmstadt Germany an exclusive license under certain of our intellectual property rights to develop and manufacture, and, if Merck KGaA, Darmstadt Germany exercises a certain continuation option, to commercialize and manufacture our compound BGB-290 and any other compound covered by the same existing patent rights with primary activity to inhibit PARP 1, 2 or 3 enzymes in the Ex-PRC Territory, and (2) Merck KGaA, Darmstadt Germany granted us an exclusive license under certain of its intellectual property rights to develop, manufacture and commercialize the licensed PARP inhibitors in the PRC Territory. Under these license agreements, we received $6 million in non-refundable payments in November 2013 following their execution and $9 million in milestone payments in 2014. We are eligible to receive up to $7 million and $2.5 million, in payments upon the successful achievement of pre-specified clinical and regulatory milestones in the PRC Territory respectively. On October 1, 2015, pursuant to a purchase of rights agreement, we repurchased all of Merck KGaA, Darmstadt Germany's worldwide rights under the ex-PRC license agreement, in consideration for, among other things, a one-time payment of $10 million and reduction of future milestone payments that we are eligible to receive under the PRC license agreement. In connection with such repurchase, the ex-PRC license agreement terminated except for certain provisions therein. The remaining $3 million of deferred revenue related to PARP as of October 1, 2015 was netted against the $10 million repurchase consideration. In addition, if Merck KGaA, Darmstadt Germany exercises its PRC commercialization option, Merck KGaA, Darmstadt Germany is required to pay us a $50 million non-refundable payment upon such exercise, and we are eligible for a $12.5 million milestone payment upon the successful achievementcommercial launch of a certain additionalproduct incurred prior to regulatory event in the PRC Territory. In consideration for the licenses grantedapproval are expensed to us, we are required to pay Merck KGaA, Darmstadt Germany a high single-digit royalty on aggregate net sales of licensed products in the PRC Territory.

        For more information on our collaborations with Merck KGaA, Darmstadt Germany, see "Part I—Item 1—Business—Collaboration with Merck KGaA, Darmstadt Germany."

        We recognized $1.1 million, $8.8 million and $13.0 million of collaboration revenue from the Merck KGaA, Darmstadt Germany Collaboration for the years ended December 31, 2016, 2015 and 2014, respectively. The following table summarizes the revenue recognition schedule of an aggregate of $34.0 million in revenue from our collaboration agreements with Merck KGaA, Darmstadt Germany, comprised of an aggregate of $22.0 million related to BGB-283 and $12.0 million related to BGB-290. The revenue consists of an upfront non-refundable license fee, Phase 1 research and development fees,expense as incurred. Cost of sales for newly launched products will not be recorded until the initial pre-launch inventory is depleted and a development based target payment related to the collaborative arrangements for BRAF, excluding the $3 million in deferred revenue that was netted against the $10 million repurchase consideration relating to the PARP inhibitors under the ex-PRC license agreement. In accordance with our revenue recognition policy, we have recognized these amounts as shown in the table below:

For the foreseeable future, we expect substantially all of our revenue will be generated from the Merck KGaA, Darmstadt Germany Collaboration, and any other strategic relationships we may enter into. If our development efforts are successful, we may also generate revenue from product sales.

Operating Expenses

Research and Development Expenses

Research and development expenses consist of the costs associated with our research and development activities, conducting preclinical studies and clinical trials and activities related to regulatory filings. Our research and development expenses consist of:

    employee-related expenses, including salaries, benefits, travel and share-based compensation expense for research and development personnel;

expenses incurred under agreements with contract research organizations, or CROs, contract manufacturing organizations, and consultants that conduct and support our clinical trials and preclinical studies;

costs of comparator drugs in certain of our clinical trials;
manufacturing costs related to pre-commercial activities;
costs associated with preclinical activities and development activities;

costs associated with regulatory operations;
employee‑related expenses, including salaries, benefits, travel and

share‑based compensation expense for research and development personnel;
in-process research and development costs expensed as part of collaboration agreements entered into; and
other expenses, which include direct and allocated expenses for rent and maintenance of facilities, insurance and other supplies used in research and development activities.

Our current research and development activities mainly relate to the clinical developmentadvancement of the following programs:

    BGB-3111, a potent and highly selectiveour internally-developed drug candidates:
zanubrutinib, an investigational small molecule inhibitor of BTK;

BGB-A317,
tislelizumab, an investigational humanized monoclonal antibody against PD-1;

BGB-290, a molecularly targeted, orally available, potent and highly selectivePD‑1;
pamiparib, an investigational small molecule inhibitor of PARP1 and PARP2; and

BGB-283,
lifirafenib, a novel small molecule inhibitor of both the monomer and dimer forms of BRAF.

BRAF;

BGB-A333, an investigational humanized monoclonal antibody against PD-L1;
BGB-A425, an investigational humanized monoclonal antibody against TIM-3;
BGB-A1217, an investigational humanized monoclonal antibody against TIGIT; and
BGB-11417, an investigational small molecular inhibitor of Bcl-2.
Research and development activities also include costs associated with in-licensed drug candidates, including:
sitravatinib, an investigational, spectrum-selective kinase inhibitor in clinical development by Mirati Therapeutics, Inc. ("Mirati");
ZW25 and ZW49, two bispecific antibody-based product candidates targeting HER2, under development by Zymeworks Inc.; and
BA3071, an investigational CAB-CTLA-4 antibody, under development by BioAtla LLC.
We expense research and development costs when we incur them. We record costs for somecertain development activities, such as clinical trials, based on an evaluation of the progress to completion of specific tasks using data such as subject enrollment, clinical site activations or information our vendors provide to us. We expense the manufacturing costs of our internally-

developed products that are used in clinical trials as they are incurred, as research and development expense. We do not allocate employee-relatedemployee‑related costs, depreciation, rental and other indirect costs to specific research and development programs because these costs are deployed across multiple product programs under research and development and, as such, are separately classified as unallocated research and development expenses.

At this time, we cannot reasonablyit is difficult to estimate or know for certain, the nature, timing and estimated costs of the efforts that will be necessary to complete the development of our internally-discovered drugs and drug candidates. We are also unable to predict when, if ever, material net cash inflows will commence from sales of our drugs and drug candidates. This is due to the numerous risks and uncertainties associated with developing such drugs and drug candidates, including the uncertainty of:

successful enrollment in and completion of clinical trials;

establishing an appropriate safety profile;

receipt of marketing approvals from applicable regulatory authorities;

successfully launching and commercializing our drugs and drug candidates, if and when approved, whether as monotherapies or in combination with our internally discovered drug candidates or third-party agents;

third‑party products;
obtaining and maintaining patent and trade secret protection and regulatory exclusivity for our drugs and drug candidates;

continued acceptable safety profiles of the products following approval;
competition from competing products; and

retention of key research and development personnel.

A change in the outcome of any of these variables with respect to the development of any of our drug candidates would significantly change the costs, timing and viability associated with the development of that drug candidate.

Research and development activities are central to our business model. We expect research and development costs to increase significantly for the foreseeable future as our development programs progress, including as we continue to support the clinical trials of BGB-3111, BGB-A317, BGB-290our drugs and BGB-283drug candidates as a treatmenttreatments for various cancers and as we move these drugs and drug candidates into additional clinical trials, including potential pivotal trials. There are numerous factors associated with the successful commercialization of any of our drugs and drug candidates, including future trial design and various regulatory requirements, many of which cannot be determined with accuracy at this time based on our stage of development. Additionally, future commercial and regulatory factors beyond our control willmay impact our clinical development and commercial programs and plans.

Selling, General and Administrative Expenses

        General

Selling, general and administrative expenses consist primarily of product promotion costs, distribution costs, salaries and related benefit costs, including share-based compensation for selling, general and administrative personnel. Other selling, general and administrative expenses include professional fees for legal, consulting, auditing and tax services as well as other direct and allocated expenses for rent and maintenance of facilities, travel costs, insurance and other supplies used in selling, general and administrative activities. We anticipate that our selling, general and administrative expenses will increase in future periods to support planned increases in commercialization activities with respect to ABRAXANE , REVLIMID , VIDAZA and tislelizumab in China and BRUKINSA in the United States and the preparation for launch and potential commercialization of our in-licensed products from our collaborations with Amgen and EUSA and internally-discovered drugs and drug candidates, if approved. We also expect selling, general and administrative expenses to increase in future periods to support our research and development activities,efforts, including the continuation of the clinical trials of BGB-3111, BGB-A317, BGB-290our drugs and BGB-283drug candidates as a treatmenttreatments for various cancers and the initiation of our clinical trials for our otherpotential new indications or drug candidates. These cost increases will likely be due to increased promotional costs, increased headcount, increased share-based compensation charges,expenses, expanded infrastructure and increased costs for insurance. We also anticipate increased legal, compliance, accounting, insurance and investor and public relations expenses associated with being a public company.

Interest Income (Expense), Net

Interest Income

Interest income consists primarily of interest generated from our short-termcash and short‑term investments in money market funds, time deposits, U.S. treasury securities municipal bonds and corporate fixed income bonds.

U.S. agency securities.

Interest Expense

Interest expense consists primarily of interest on our senior promissory note, convertible promissory notelong‑term bank loans and long-term bankshareholder loan.


        In 2011, we issued a $10 million, 8% senior promissory note and a $10 million 8% subordinated convertible promissory note, compounded annually, each to MSD. We also issued an aggregate principal amount of $3.1 million convertible promissory notes to several other investors in 2012 and 2014, all bearing interest of 8% per annum for the first three years and 15% per annum for the remaining term. In October 2014, we completed a Series A preferred share financing, as a result of which, the $10 million MSD subordinated convertible promissory note was automatically converted into 18,518,519 Series A preferred shares, and the other $3.1 million principal amount of convertible promissory notes, along with accrued interest was automatically converted into 5,470,705 Series A preferred shares. We recognized a gain on debt extinguishment of $2.9 million due to the forfeiture of interest upon the conversion, as only the principal amount of the Merck subordinated convertible promissory note was eligible for conversion. In February 2016, in connection with the closing of our initial public offering, the outstanding unpaid principal and interest of the MSD Senior Promissory Note was automatically exchanged into 7,942,314 of our ordinary shares.

        On September 2, 2015, BeiGene (Suzhou) Co., Limited, or BeiGene Suzhou, entered into a loan agreement with Suzhou Industrial Park Biotech Development Co., Ltd. and China Construction Bank, to borrow $17.3 million at a 7% fixed annual interest rate. As of December 31, 2016, we have drawn down $17.3 million, which is secured by BeiGene Suzhou's equipment with a carrying amount of $22.3 million and our rights to a PRC patent on a drug candidate. The loan amounts of $8.7 million and $8.6 million are repayable on September 30, 2018 and 2019, respectively.

Other Income (Expense), Net

Other income consists primarily of government grants and subsidies received that involve no conditions or continuing performance obligations by us. Other expense consists primarilyus, realized and unrealized gains and losses related to foreign currency exchange rates and gains on the sale of loss from property and equipment disposals and donations made to sponsor certain events.

Operating Capital Requirements

We have exclusive rights to distribute and promote BMS’s approved cancer therapies in China, for which we began recognizing revenue in the third quarter of 2017. We received accelerated approval from the FDA for BRUKINSA as a treatment for MCL in adult patients who have received at least one prior therapy on November 14, 2019; and regulatory approval from the NMPA for tislelizumab as a treatment for patients with cHL who have received at least two prior therapies on December 27, 2019. We launched BRUKINSA in the United States in November 2019 and expect to launch tislelizumab in China in 2020. However, we do not expect to generate significant revenue from product sales of our internally-developed drugs and drug candidates unless and until we obtain regulatory approval of and commercialize onefor additional indications of our current or future drug candidates.currently approved drugs. We anticipate that we will continue to generate losses for the foreseeable future and we expect the losses to increase as we continue the development of, and seek regulatory approvals for, our drugs and drug candidates, commercialize our approved products and prepare for commercialization and begin to commercialize any future approved products. As a newlygrowing public company, we will continue to incur additional costs associated with operating as a public company.our operations. In addition, subject to obtaining regulatory approval of any of our drug candidates, we expect to incur significant commercialization expenses for product sales, marketing and manufacturing. Accordingly, we anticipatemanufacturing of our in-licensed drug products as well as our internally developed products that we willare either approved or in late-stage clinical trials. We may need substantial additional funding in connection withprior to generating sufficient cash from operations to fund our continuing operations.

Based on our current operating plan, we expect that our existing cash, cash equivalents and short-term investments as of December 31, 2016,2019, will enable us to fund our operating expenses and capital expenditures requirements for at least the next 15 months.12 months after the date that the financial statements included in this report are issued. In addition to the cash, cash equivalents and short-term investments as of December 31, 2019, we received $2.8 billion in cash upon Amgen's purchase of a 20.5% equity stake in the Company on January 2, 2020. We expect that our expenses will continue to increase substantially as we fund clinical development of BGB-3111, BGB-A317, BGB-290 and BGB-283, fund new andour ongoing research and clinical development activitiesefforts, including our ongoing and planned pivotal trials for zanubrutinib, tislelizumab and pamiparib, both in China and globally, and the shared development costs of Amgen's 20 oncology pipeline products and additional in-licensed drug candidates; our other ongoing and planned clinical trials; regulatory filing and registration of our late-stage drug candidates; expansion of our commercial operations in China and the U.S. and the launch of our in-licensed commercial drug portfolio and late-stage drug candidates globally; business development and manufacturing activities; and working capital and other general corporate purposes. We have based our estimates on assumptions that may prove to be wrong, and we may use our available capital resources sooner than we currently expect.expect in our current operating plan. Because of the numerous risks and uncertainties associated with the development and commercialization of our drugs and drug candidates, we are unable to estimate the amounts of increased capital outlays and operating expenditures necessary to complete the development and commercialization of our drug candidates.

Our future capital requirements will depend on many factors, including:

our ability to successfully commercialize our internally developed and in-licensed drugs;
the costs, timing and outcome of regulatory reviews and approvals;

the ability of our drug candidates to progress through clinical development successfully;

the initiation, progress, timings,timing, costs and results of nonclinical studies and clinical trials for our other programs and potential drug candidates;

the number and characteristics of the drugs and drug candidatecandidates we pursue;

the costs of establishing or expanding commercial manufacturing capabilities or securing necessary supplies from third-party manufacturers;
the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-relatedproperty‑related claims;
the costs of establishing and expanding our commercial operations and the success of those operations;


the extent to which we acquire or in-licensein‑license other products and technologies; and

our ability to maintain and establish collaboration arrangements on favorable terms, if at all.

Until such time, if ever, as we can generate substantial product revenue, we expectmay be required to finance our cash needs through a combination of equity offerings, debt financings, collaborations,collaboration agreements, strategic alliances, licensing arrangements, government grants and government grants.other available sources. Under SEC rules, we currently qualify as a “well-known seasoned issuer,” which allows us to file shelf registration statements to register an unspecified amount of securities that are effective upon filing. On May 26, 2017, we filed such a shelf registration statement with the SEC for the issuance of an unspecified amount of ordinary shares (including in the form of ADSs), preferred shares, various series of debt securities and/or warrants to purchase any of such securities, either individually or in units, from time to time at prices and on terms to be determined at the time of any such offering. This registration statement was effective upon filing and will remain in effect for up to three years from filing, at which time we may file another shelf registration statement that will be effective for up to three years from filing. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our shareholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as an ADS holder.a holder of ADSs or ordinary shares. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends and may require the issuance of warrants, which could potentially dilute your ownership interest. If we raise additional funds through collaborations,collaboration agreements, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams or research programs or to grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings, collaborations or other sources when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market products or drug candidates that we would otherwise prefer to develop and market ourselves.

As of December 31, 2016,2019, we have drawn down $17.3the entire $83.3 million which is secured by BeiGene Suzhou's equipment with a carrying(RMB580.0 million) in aggregate principal amount of $22.3this loan. Maturity dates range from 2021 to 2027.

Shareholder Loan
On March 7, 2017, BeiGene Biologics entered into a Shareholder Loan Contract with Guangzhou GET Technology Development Co., Ltd. (now Guangzhou High-tech Zone Technology Holding Group Co., Ltd.) ("GET"), pursuant to which, GET provided a shareholder loan to BeiGene Biologics in the principal amount of RMB900.0 million at a fixed 8% annual interest rate. The term of the shareholder loan is 72 months, commencing from the actual drawdown date of April 14, 2017 and our rights to a PRC patentending on a drug candidate. The loan amountsApril 13, 2023, unless converted earlier. On April 14, 2017, we drew down the entire RMB900.0 million from GET, which remains outstanding as of $8.7 million and $8.6 million are repayable on September 30, 2018 and 2019, respectively.

December 31, 2019.

Capital Commitments

We had capital commitments amounting to $4.5$42.1 million for the acquisition of property, plant and equipment as of December 31, 2016,2019, which was primarily for building BeiGene Suzhou'sGuangzhou Factory’s manufacturing facility and expansion of BGC's research and development activities in Suzhou,Guangzhou, China.

Other Business Agreements

We enter into agreements in the normalordinary course of business with CROs to provide research and institutions to license intellectual property. We have not included these future payments in the table of contractual obligations above since thedevelopment services. These contracts are generally cancelable at any time by us with prior written notice.

Off-Balance

We also enter into collaboration agreements with institutions and companies to license intellectual property. We may be obligated to make future development, regulatory and commercial milestone payments and royalty payments on future sales of specified products associated with its collaboration agreements. Payments under these agreements generally become due and payable upon achievement of such milestones or sales. These commitments are not recorded on our balance sheet because the achievement and timing of these milestones are not fixed and determinable. When the achievement of these milestones or sales have occurred, the corresponding amounts are recognized in our financial statements.
Off‑Balance Sheet Arrangements

We did not have during the periods presented, and we do not currently have, any off-balanceoff‑balance sheet arrangements, as defined under SEC rules, such as relationships with unconsolidated entities or financial partnerships, which are often referred to as structured finance or special purpose entities, established for the purpose of facilitating financing transactions that are not required to be reflected on our balance sheets.

Critical Accounting Policies and Significant Judgments and Estimates

Our discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America or GAAP.("GAAP"). The preparation of these financial statements requires us to make estimates, assumptions and assumptionsjudgments that affect the reported amounts of assets, liabilities, revenues, costs and the disclosure of contingent assets and liabilities at the date of our financial statements and the reported amounts of revenues and expenses during the periods.expenses. We evaluate our estimates and judgments on an ongoing basis, including but not limited to, estimating the useful lives of long-lived assets, identifying separate accounting units and estimating the best estimate selling price of each deliverable in our revenue arrangements, assessing the impairment of long-lived assets, share-based compensation expenses, realizability of deferred tax assets and the fair value of warrant and option liabilities.actual results may differ from these estimates. We base our estimates on historical experience, known trends and events, contractual milestones and other various factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources.
Our actual resultsmost critical accounting policies are summarized below. See Note 2 to our consolidated financial statements included in this Annual Report for a description of our other significant accounting policies.
Revenue Recognition
Effective January 1, 2018, we adopted Accounting Standards Codification, Topic 606, Revenue from Contracts with Customers (“ASC 606”). For further information regarding the impact of adoption, see Note 2 Recent Accounting Pronouncements.

Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price, including variable consideration, if any; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration to which it is entitled in exchange for the goods or services it transfers to the customer.
Once a contract is determined to be within the scope of ASC 606 at contract inception, we review the contract to determine which performance obligations it must deliver and which of these performance obligations are distinct. We recognize as revenue the amount of the transaction price that is allocated to each performance obligation when that performance obligation is satisfied or as it is satisfied.
Product Revenue
Our product revenues are generated from the sale of ABRAXANE, REVLIMID, and VIDAZA to our product distributor in China, our sole customer in China. The first tier distributor subsequently resells the products to second tier distributors, who ultimately sell the products to health care providers and patients. Following FDA approval on November 14, 2019, we began selling our first internally developed drug, BRUKINSA, in the United States to specialty pharmacies and specialty distributors, our U.S. customers. The specialty pharmacies and specialty distributors subsequently resell the product to health care providers and patients. We are the principal under the product sales as we control the products with the ability to direct the use of, and obtain substantially all the remaining benefits from the products before they are sold to the customer. For product sales transactions, we have a single performance obligation which is to sell the products to our customer. We include variable consideration in the transaction price to the extent it is probable that a significant reversal will not occur and estimate variable consideration from rebates, chargebacks, trade discounts and allowances, sales returns allowances and other incentives using the expected value method. Revenues for product sales are recognized at a point in time when the single performance obligation is satisfied upon delivery to the customer. Our payment terms are approximately 60-90 days. Actual amounts of consideration ultimately received may differ from our estimates. We will reassess estimates for variable consideration periodically. If actual results in the future vary from our estimates, we will adjust these estimates, under different assumptionswhich would affect net product revenue and earnings in the period such variances become known.
In China, rebates, including price compensation credits, are offered to distributors, consistent with pharmaceutical industry practices. We record a provision for rebates at the time of sale based on contracted rates and historical redemption rates. Assumptions used to establish the provision include the level of distributor inventories, sales volumes and contract pricing and estimated acceptance of government pricing or conditions.

reimbursement amounts (such as provincial acceptance of the National Reimbursement Drug List pricing in the PRC). We believeregularly review the following critical accounting policies reflect our more significantinformation related to these estimates and assumptions usedadjust the provision accordingly.

In the United States, estimates for variable consideration for which reserves are established at the time of sale include government rebates, chargebacks, trade discounts and allowances, sales returns allowances and other incentives that are offered within contracts between the Company and our U.S. customers, health care providers and other indirect customers. Where appropriate, these estimates take into consideration a range of possible outcomes that are probability-weighted for relevant factors such as our historical experience, current contractual and statutory requirements, specific known market events and trends, industry data and forecasted customer buying and payment patterns. U.S. product revenues and related reserves for variable consideration were not significant for the year ended December 31, 2019 as we did not begin generating product revenue in the preparationUnited States until after BRUKINSA received FDA approval on November 14, 2019.
We base our sales returns allowance on estimated distributor inventories, customer demand as reported by third-party sources, and actual returns history, as well as other factors, as appropriate. For newly launched products where actual returns history is not yet available, the sales returns allowance is initially calculated based on benchmarking data from similar products and industry experience. If the historical or benchmarking data we use to calculate these estimates do not properly reflect future returns, then a change in the allowance would be made in the period in which such a determination is made and revenues in that period could be materially affected. Any changes from the historical trend rates are considered in determining the current sales return allowance. To date, sales returns have not been significant.
Collaboration Revenue
At contract inception, we analyze our collaboration arrangements to assess whether they are within the scope of ASC 808, Collaborative Arrangements (“ASC 808”) to determine whether such arrangements involve joint operating activities performed by parties that are both active participants in the activities and exposed to significant risks and rewards dependent on

the commercial success of such activities. For collaboration arrangements within the scope of ASC 808 that contain multiple elements, we first determine which elements of the collaboration are deemed to be within the scope of ASC 808 and those that are more reflective of a vendor-customer relationship and therefore within the scope of ASC 606. For elements of collaboration arrangements that are accounted for pursuant to ASC 808, an appropriate recognition method is determined and applied consistently.  
In determining the appropriate amount of revenue to be recognized as we fulfill our obligations under each of our financial statements.

Revenue Recognition

        We recognize revenues from research and development collaborative arrangements when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered,agreements, we perform the


fee is fixed or determinable, and there is reasonable assurance that the related amounts are collectible in accordance with five-step model under ASC 605,Revenue Recognition, or ASC 605. 606 noted above.

Our collaborative arrangements may contain multiple elements,more than one unit of account, or performance obligation, including grants of licenses to intellectual property rights, agreementagreements to provide research and development services and other deliverables. The deliverables under such arrangements are evaluated under ASC 605-25,Multiple-Element Arrangements. Pursuant to ASC 605-25, each required deliverable is evaluated to determine whether it qualifies as a separate unit of accounting based on whether the deliverable has "stand-alone value" to the customer. The collaborative arrangements do not include a right of return for any deliverable. The arrangement's considerationAs part of the accounting for these arrangements, we must develop assumptions that is fixed or determinable, excluding contingent payments, is then allocatedrequire judgment to each separate unit of accounting based ondetermine the relative selling price of each deliverable. The relativestand-alone selling price for each deliverable is determined using vendor specific objective evidence, or VSOE, ofperformance obligation identified in the contract. In developing the stand-alone selling price for a performance obligation, we consider competitor pricing for a similar or third-party evidence, or TPE,identical product, market awareness of selling price if VSOE does not exist. If neither VSOE nor TPE exists, we use the best estimateand perception of the selling price, or BESP, for the deliverable.product, expected product life and current market trends. In general, the consideration allocated to each unit of accountingperformance obligation is recognized aswhen the related goodsrespective obligation is satisfied either by delivering a good or services are delivered,providing a service, limited to the consideration that is not contingent upon future deliverables.constrained. Non-refundable payments received before all of the relevant criteria for revenue recognition are satisfied are recorded as advances from customers.

Licenses of Intellectual Property: Upfront non-refundable payments for licensing our intellectual property are evaluated to determine if the licensee can obtain stand-alone valuelicense is distinct from the other performance obligations identified in the arrangement. For licenses determined to be distinct, we recognize revenues from non-refundable, up-front fees allocated to the license separateat a point in time, when the license is transferred to the licensee and the licensee is able to use and benefit from the valuelicense.  
Research and Development Services: The portion of the transaction price allocated to research and development services and other deliverables in the arrangement to be provided by us. We act as the principal under our arrangements and licensing intellectual propertyperformance obligations is part of our ongoing major or central operations. The license right is not contingent upon the delivery of additional items or meeting other specified performance conditions. Therefore, when stand-alone value of the license is determinable, the allocated consideration isdeferred and recognized as collaboration revenue upon delivery of the license rights.

        As we actovertime as the principal under our arrangements, and research and development services are also part of our ongoing major or central operations, we recognize the allocated consideration related to reimbursements of research and development costs as collaboration revenue when delivery or performance of such services occurs.

        Product R&D reimbursement revenue for revenue attributable to the clinical trials that BMS opted into is recognized as delivery or performance of such services occurs.

Milestone Payments: At the inception of each arrangement that includes development royaltiesmilestone payments, we evaluate whether the milestones are considered probable of being reached and commercial event payments, collectively referredestimates the amount to as target payments, under collaborative arrangements are triggered either by the results of our research and development efforts, achievement of regulatory goals or by specified sales results by a third-party collaborator. Under ASC 605-28,Milestone Method of Revenue Recognition, an accounting policy election can be made to recognize a payment that is contingent upon the achievement of a substantive milestone in its entiretyincluded in the periodtransaction price using the most likely amount method.  If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in which the milestone is achieved. We elected not to adopt the milestone method of revenue recognition under ASC 605-28.

        Targetstransaction price. Milestones related to our development-based activities may include initiation of various phases of clinical trials and applications and acceptance for product approvals by regulatory agencies.trials. Due to the uncertainty involved in meeting these development-based targets, we would account for development-based targets as collaboration revenue upon achievement ofthey are generally fully constrained at contract inception. We will assess whether the respective development target. Royaltiesvariable consideration is fully constrained each reporting period based on reported sales of licensed productsthe facts and circumstances surrounding the clinical trials. Upon changes to constraint associated with the developmental milestones, variable consideration will be recognized as collaboration revenue based on contract terms when reported sales are reliably measurable and collectability is reasonably assured. Targets related to commercial activities may be triggered upon events such as first commercial sale of a product or when sales first achieve a defined level. Since these targets would be achieved after the completion of our development activities, we would account for the commercial event targetsincluded in the same manner as royalties, with collaborationtransaction price when a significant reversal of revenue recognized upon achievement of the target. To date, none of the products have been approved. Hence, no revenue has been recognized relatedis not expected to royalties or commercial event based targets in any of the periods presented.


        Any subsequent payments to be madeoccur and allocated to the collaborator such as profit sharingseparate performance obligations. Regulatory milestones are fully constrained until the period in which those regulatory approvals are achieved due to the inherent uncertainty with the approval process. Regulatory milestones are included in the transaction price in the period regulatory approval is obtained.

Royalties: For arrangements that include sales-based royalties, including milestone payments based on netthe level of sales, that are notand the license is deemed to be the predominant item to which the royalties relate, we recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to research and development services would be recorded as expenses fromwhich some or all of the collaborative arrangement. To date, no payments haveroyalty has been made to the collaborator.

allocated has been satisfied (or partially satisfied). 

Research and Development Expenses

Research and development expenses represent costs associated with the collaborative arrangements, which primarily include (1) payroll and related costs (including share-basedshare‑based compensation) associated with research and development personnel; (2) costs related to clinical trials and preclinical testing of our technologies under development; (3) costs to develop the product candidates, including raw materials and supplies, product testing, depreciation, and facility related expenses; (4) expenses for research services provided by universities and contract laboratories, including sponsored research funding; and (5) other research and development expenses. Research and development expenses are charged to expense as incurred when these expenditures relate to our research and development services and have no alternative future uses.

Clinical trial costs are a significant component of our research and development expenses. We have a history of contracting with third parties that perform various clinical trial activities on behalf of us in the ongoing development of our product candidates. Expenses related to clinical trials are accrued based on our estimates of the actual services performed by the third parties for the respective period. If the contracted amounts are modified (for instance, as a result of changes in the clinical trial

protocol or scope of work to be performed), we will modify the related accruals accordingly on a prospective basis. Revisions in the scope of a contract are charged to expense in the period in which the facts that give rise to the revision become reasonably certain.

The process of estimating our research and development expenses involves reviewing open contracts and purchase orders, communicating with our personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated costs incurred for the services when we have not yet been invoiced or otherwise notified of the actual costs. The majority of our service providers invoice us in arrears for services performed, on a pre-determinedpre‑determined schedule or when contractual milestones are met; however, some require advanced payments. We make estimates of our expenses as of each balance sheet date in our financial statements based on facts and circumstances known to us at that time. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may result in us reporting expenses that are too high or too low in any particular period. To date, we have not made any material adjustments to our prior estimates of research and development expenses.

Share-Based

Acquired In-Process Research and Development Expense
We have acquired rights to develop and commercialize drug products and product candidates. Upfront payments that relate to the acquisition of a new drug compound, as well as pre-commercial milestone payments, are immediately expensed as acquired in-process research and development in the period in which they are incurred, provided that the new drug compound did not also include processes or activities that would constitute a “business” as defined under GAAP, the drug has not achieved regulatory approval for marketing and, absent obtaining such approval, has no established alternative future use. Milestone payments made to third parties subsequent to regulatory approval are capitalized as intangible assets and amortized over the estimated remaining useful life of the related product. Royalties owed on sales of the products licensed pursuant to the agreements are expensed in the period the related revenues are recognized.
Share‑Based Compensation

Awards Granted to Employees

We apply ASC 718,Compensation—Stock Compensation or ("ASC 718,718") to account for our employee share-basedshare‑based payments. In accordance with ASC 718, we determine whether an award should be classified and accounted for as a liability award or equity award. All our grants of share-basedshare‑based awards to employees were classified as equity awards and are recognized in the financial statements based on their grant date fair values. We have elected to recognize compensation expense using the straight-linestraight‑line method for all employee equity awards granted with graded vesting based on service conditions provided that the amount of compensation cost recognized at any date is at least equal to the portion of the grant-dategrant‑date value of the options that are vested at that date. We use the accelerated method for all awards granted with graded vesting based on performance conditions. To the extent the required vesting conditions are not met resulting in the forfeiture of the share-basedshare‑based awards, previously recognized compensation expense relating to those awards are reversed. ASC 718 requires forfeitures to


be estimated at the time of grant and revised, if necessary, in the subsequent period if actual forfeitures differ from initial estimates.

Forfeiture rates are estimated based on historical and future expectations of employee turnover rates and are adjusted to reflect future changes in circumstances and facts, if any. Share-basedShare‑based compensation expense is recorded net of estimated forfeitures such that expense is recorded only for those share-basedshare‑based awards that are expected to vest. To the extent we revise these estimates in the future, the share-basedshare‑based payments could be materially impacted in the period of revision, as well as in following periods. We, with the assistance of an independent third-partythird‑party valuation firm, determined the estimated fair value of the share options granted to employees. Theemployees using a binomial option pricing model was applied in determining the estimated fair value of the options granted to employees.

model.

Awards Granted to Non-employees

Non‑Employees

We have accounted for equity instruments issued to non-employeesnon‑employees in accordance with the provisions of ASC 718, Share-based payments, and ASC 505,Equity. All transactions in which goods or services are received in exchange for equity instruments are accounted for based on the fair value of the consideration received or the fair value of the equity instrument issued, whichever is more reliably measurable. The measurement date of the fair value of the equity instrument issued is the date on which the counterparty'scounterparty’s performance is completed as there is no associated performance commitment. The expense is recognized in the same manner as if we had paid cash for the services provided by the non-employeesnon‑employees in accordance with ASC 505-50,Equity-based505‑50, Equity‑based payments to non‑employees. We estimate the fair value of share options granted to non-employees.

using the same method as employees.

Modification of Awards


A change in any of the terms or conditions of the awards is accounted for as a modification of the award. Incremental compensation cost is measured as the excess, if any, of the fair value of the modified award over the fair value of the original award immediately before its terms are modified, measured based on the fair value of the awards and other pertinent factors at the modification date. For vested awards, we recognize incremental compensation cost in the period the modification occurs. For unvested awards, we recognize over the remaining requisite service period, the sum of the incremental compensation cost and the remaining unrecognized compensation cost for the original award on the modification date. If the fair value of the modified award is lower than the fair value of the original award immediately before modification, the minimum compensation cost we recognize is the cost of the original award.

Significant Factors, Assumptions, and Methodologies Used in Determining Fair Value

The fair value of each share option grant is estimated using the binomial option-pricingoption‑pricing model. The model requires the input of highly subjective assumptions including the estimated expected share price volatility and, the share price upon which (i.e. the exercise multiple) the employees are likely to exercise share options. The trading history and observation period of our own share price movement has not been long enough to match the life of the share option. Therefore, we estimate our expected share price volatility based on the historical volatility of a group of similar companies, which are publicly-traded.publicly‑traded. When selecting these public companies on which we have based our expected share price volatility, we selected companies with characteristics similar to us, including the invested capital'scapital’s value, business model, development stage, risk profiles, position within the industry, and with historical share price information sufficient to meet the contractual life of our share-basedshare‑based awards. We will continue to apply this process until a sufficient amount of historical information regarding the volatility of our own share price becomes available. For the exercise multiple, we were not able to develop an exercise pattern as reference, thus the exercise multiple is based on management'smanagement’s estimation, which we believe is representative of the future exercise pattern of the options. The risk-freerisk‑free interest rates for the periods within the contractual life of the option are based on the U.S. Treasury yield curve in effect


during the period the options were granted. Expected dividend yield is based on the fact that we have never paid, and do not expect to pay cash dividends in the foreseeable future.

The assumptions adopted to estimate the fair value of share options using the binomial option pricing model were as follows:

We are also required to estimate forfeitures at the time of grant, and revise those estimates in subsequent periods if actual forfeitures differ from our estimates. We use historical data to estimate pre-vestingpre‑vesting option forfeitures and record share-basedshare‑based compensation expense only for those awards that are expected to vest. To the extent that actual forfeitures differ from our estimates, the difference is recorded as a cumulative adjustment in the period the estimates were revised.

These assumptions represented our best estimates, but the estimates involve inherent uncertainties and the application of our judgment. As a result, if factors change and we use significantly different assumptions or estimates when valuing our share options, our share-basedshare‑based compensation expense could be materially different.

The fair value of restricted shares and restricted share units are based on the closing market price of our ADSs on the NASDAQ Global Select Market on the date of grant.

As of December 31, 2015,2018, there was $15.63$289.9 million of total unrecognized share-based compensation expenses,expense, net of estimated forfeitures, related to unvested share-based awards which are expected to be recognized over a weighted-average period of 2.322.6 years. In future periods, our share-based compensation expense is expected to increase as a result of recognizing our existing unrecognized share-based compensation for awards that will vest and as we issue additional share-based awards to attract and retain our employees.


Fair Value Estimate

Fair value of ordinary shares

        With the completion of our initial public offering in February 2016, a public trading market for the ADSs has been established, and it is no longer necessary for our board of directors to estimate the fair value of our ordinary shares in connection with our accounting for granted share options and restricted shares.

        Prior to our initial public offering, we were required to estimate the fair value of the ordinary shares underlying our share-based awards when performing the fair value calculations with the binomial option model. Therefore, our board of directors estimated the fair value of our ordinary shares at various dates, with input from management, considering the third-party valuations of ordinary shares at each grant date. The valuations of our ordinary shares were performed using methodologies, approaches and assumptions consistent with the American Institute of Certified Public Accountants Audit and Accounting Practice Aid Series:Valuation of Privately-Held-Company Equity Securities Issued as Compensation, or the AICPA Practice Guide. In addition, our board of directors considered various objective and subjective factors, along with input from management and the independent third-party valuation firm, to determine the fair value of our ordinary shares, including: external market conditions affecting the biopharmaceutical industry, trends within the biopharmaceutical industry, the prices at which we sold preferred shares, the superior rights and preference of the preferred shares or other senior securities relative to our ordinary shares at the time of each grant, the results of operations, financials position, status of our research and development efforts, our stage of development and business strategy, and the lack of an active public market for our ordinary shares, and the likelihood of achieving a liquidity event such as an initial public offering. The option-pricing method was used to allocate the invested capital's enterprise value to preferred shares or other senior securities and ordinary shares, taking into account the guidance prescribed by the AICPA Practice Guide. This method treats ordinary shares and preferred shares or other senior securities as call options on the invested capital's value, with exercise prices based on their respective payoffs upon a liquidity event.

        In determining the invested capital's value, we applied the discounted cash flow analysis based on our projected cash flow using our best estimate as of the valuation date. The determination of our invested capital's value requires complex and subjective judgments to be made regarding our projected financial and operating results, our unique business risks, and our operating history and prospects at the time of valuation.

Fair value of options and restricted shares

        Our board of directors determined the fair value of our share options and the restricted shares as of the date of grant, taking into consideration the various objective and subjective factors described above, including the conclusion of valuation of our ordinary shares as of dates close to the grant dates of our share options and the restricted shares discussed below. We computed the per share weighted-average estimated fair value for share option grants based on the binomial option pricing model and the per share weighted-average estimated fair value for restricted shares based on per share estimated fair value of ordinary shares as of the date of grant.

Derivative Instruments

        ASC 815,Derivatives and Hedging, requires all contracts which meet the definition of a derivative to be recognized in the consolidated financial statements as either assets or liabilities and recorded at fair value. Changes in the fair value of derivative financial instruments are either recognized periodically in income/loss or in shareholders' deficit as a component of other comprehensive income depending on the use of the derivative and whether it qualifies for hedge accounting. Changes in fair values of derivatives not qualified as hedges are reported in the consolidated statements of operations.


The estimated fair values of derivative instruments are determined at discrete points in time based on the relevant market information. We calculated these estimates with reference to the market rates using industry standard valuation techniques with the assistance of an independent third-party valuation firm.

Fair value estimation on the exercise dates

        The warrants in connection with the convertible promissory notes and the option to purchase shares by rental deferral were exercised in January and February 2016. The fair values of the warrants and option liabilities were determined using significant other observable inputs (Level 2), estimated using the intrinsic value, which equals to the difference between the share price at the IPO closing date and the exercise price, as the exercise dates were immediately prior to or very close to the IPO closing date.

Fair value estimation prior to the exercise dates

        As presented in the prior subsection, "Fair Value Estimate," we applied the discounted cash flow analysis to estimate the invested capital's value as of various valuation dates and the option-pricing method was used to allocate the invested capital's value to preferred shares or other senior securities and ordinary shares. The derived fair value of ordinary share and preferred shares was then further used as inputs to the Black-Scholes option pricing model to estimate the fair value of the derivative instruments. The Black-Scholes option pricing model requires the input of highly subjective assumptions, including the risk-free interest rate, the expected volatility of the underlying stock and the expected life of the derivative instruments. These estimates involve inherent risk and uncertainties and the application of management's judgment. To determine the expected life of the derivative instruments, we have considered factors including the timing of expected various liquidity events and their respective probabilities as well as the contractual life of the derivative instruments. The risk-free interest rates for the periods within the expected life of the option are based on the U.S. Treasury yield curve. We historically have been a private company and lack company-specific historical and implied volatility information. Therefore, we estimate our expected volatility based on the historical volatility of a group of similar companies, which are publicly-traded.

        We have measured the warrants and option liabilities at fair values on a recurring basis using significant unobservable inputs (Level 3) as of December 31, 2015. The significant unobservable inputs


used in the fair value measurement and the corresponding impacts to the fair values are presented below:

Income Taxes

We use the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and the tax bases of assets and liabilities and are measured using enacted tax rates and laws that will be in effect when the differences are expected to reverse. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized.

        In November 2015, the FASB issued Accounting Standards Update 2015-17, Balance Sheet Classification of Deferred Taxes, which requires deferred income tax assets and liabilities to be classified as non-current in a classified balance sheet, and eliminates the prior guidance, which required an entity to separate deferred tax assets and liabilities into a current amount and a non-current amount in a classified balance sheet. We changed the manner in which we classify deferred tax assets and liabilities retrospectively from the fourth quarter of 2016 due to the early adoption of Accounting Standards Update 2015-17. The adoption of this guidance has no impact on prior year balances as current deferred tax assets and liabilities are both nil as of December 31, 2015.

We evaluate our uncertain tax positions using the provisions of ASC 740,Income Taxes, which requiresprescribes a recognition threshold that realization of an uncertain incomea tax position beis required to meet before being recognized in the financial statements. The benefit to be recordedWe recognize in the financial statements the benefit of a tax position which is the amount most“more likely than not” to be realizedsustained under examination based solely on the technical merits of the position assuming a review by tax authorities having all relevant information and applying current conventions.information. Tax positions that meet the recognition threshold are measured using a cumulative probability approach, at the largest amount of tax benefit that has a greater than fifty percent likelihood of being realized upon settlement. It is our policy to recognize interest and penalties related to unrecognized tax benefits, if any, as a component of income tax expense.


Recent Accounting Pronouncements

See Note 2 to our consolidated financial statements included in this Annual Report on Form 10-K for information regarding recent accounting pronouncements.

JOBS Act

        Under Section 107(b) of the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, an "emerging growth company" can delay the adoption of new or revised accounting standards until such time as those standards would apply to private companies. We have irrevocably elected not to avail ourselves of this exemption and, as a result, we will adopt new or revised accounting standards at the same time as other public companies that are not emerging growth companies. There are other exemptions and reduced reporting requirements provided by the JOBS Act that we are currently evaluating. For example, as an emerging growth company, we are exempt from Sections 14A(a) and (b) of the Exchange Act which would otherwise require us to (1) submit certain executive compensation matters to shareholder advisory votes, such as "say-on-pay," "say-on-frequency" and "golden parachutes;" and (2) disclose certain executive compensation related items such as the correlation between executive compensation and performance and comparisons of our chief executive officer's compensation to our median employee compensation. We also rely on an exemption from the rule requiring us to provide an auditor's attestation report on our internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act and the rule requiring us to comply with any requirement that may be adopted by the PCAOB regarding mandatory audit firm rotation or a supplement to the auditor's report providing additional information about the audit and the financial statements, known as the auditor discussion and analysis. We will continue to remain an "emerging growth company" until the earliest of the following: (1) the last day of the fiscal year following the fifth anniversary of the date of the completion of our initial public offering, (2) the last day of the fiscal year in which our total annual gross revenue is equal to or more than $1 billion, (3) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years, or (4) the date on which we are deemed to be a large accelerated filer under the rules of the SEC.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Interest and Credit Risk

Financial instruments that are potentially subject to credit risk consist of cash and cash equivalents, restricted cash and short-termshort term investments. The carrying amounts of cash, and cash equivalents, restricted cash and short-termshort term investments represent the maximum amount of loss due to credit risk. We had cash and cash equivalents of $87.5$618.0 million, $17.9$712.9 million and $13.9$239.6 million, restricted cash of $2.8 million, $27.8 million and short termnil, and short-term investments of $280.7$364.7 million, $82.6 million$1.1 billion and $30.5$597.9 million at December 31, 2016, 20152019, 2018 and 2014,2017, respectively. At December 31, 2016, ourOur cash and cash equivalents wereare deposited with various major reputable financial institutions located in the PRC and international financial institutions outside ofwithin or without the PRC. The deposits placed with these financial institutions are not protected by statutory or commercial insurance. In the event of bankruptcy of one of these financial institutions, we may be unlikely to claim our deposits back in full. We believe that these financial institutions are of high credit quality, and we continually monitor the credit worthiness of these financial institutions. At December 31, 20162019, our short-termshort term investments consisted primarily of U.S. Treasurytreasury securities. We believe that the U.S. Treasurytreasury securities areis of high credit quality and continually monitor the credit worthiness of these institutions.

The primary objectives of our investment activities are to preserve principle,principal, provide liquidity and maximize income without significant increasing risk. Our primary exposure to market risk relates to fluctuations in the interest rates which are affected by changes in the general level of PRC and U.S. interest rates. Given the short-termshort‑term nature of our cash equivalents, we believe that a sudden change in


market interest rates would not be expected to have a material impact on our financial condition and/or results of operation. We estimate that a hypothetical 100-basis100‑basis point change in market interest rates would impact the fair value of our investment portfolio as of December 31, 20162019 by $1.6$1.1 million.


We do not believe that our cash, cash equivalents and short-termshort‑term investments have significant risk of default or illiquidity. While we believe our cash, and cash equivalents and short-term investments do not contain excessive risk, we cannot provide absolute assurance that in the future investments will not be subject to adverse changes in market value.

Currency Convertibility Risk
A significant portion of our expenses, assets and liabilities are denominated in RMB. On January 1, 1994, the PRC government abolished the dual rate system and introduced a single rate of exchange as quoted daily by the People’s Bank of China (the "PBOC"). However, the unification of exchange rates does not imply that the RMB may be readily convertible into U.S. dollars or other foreign currencies. All foreign exchange transactions continue to take place either through the PBOC or other banks authorized to buy and sell foreign currencies at the exchange rates quoted by the PBOC. Approvals of foreign currency payments by the PBOC or other institutions require submitting a payment application form together with suppliers’ invoices, shipping documents and signed contracts.
Additionally, the value of the RMB is subject to changes in central government policies and international economic and political developments affecting supply and demand in the PRC foreign exchange trading system market.
Foreign Currency Exchange Rate Risk

We are exposed to foreign exchange risk arising from various currency exposures. Our functionalreporting currency is the U.S. dollar, but a portion of our operating transactions and assets and liabilities are in other currencies, such as RMB, Australian dollar and Euro. We do not believe that we currently have any significant direct foreign exchange risk and have not used any derivative financial instruments to hedge exposure to such risk.

RMB is not freely convertible into foreign currencies for capital account transactions. The value of RMB against the U.S. dollar and other currencies is affected by, among other things, changes in China'sChina’s political and economic conditions and China'sChina’s foreign exchange prices. From July 21, 2005, the RMB is permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. For the RMB against U.S. dollars, there waswere depreciation of approximately 6.3%1.3%, 4.4%depreciation of approximately 5.7% and 2.4%appreciation of approximately 6.5% in the year ended December 31, 2016, 20152019, 2018 and 2014.2017. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between the RMB and the U.S. dollar in the future.

To the extent that we need to convert U.S. dollars into RMB for capital expenditures and working capital and other business purpose,purposes, appreciation of RMB against the U.S. dollar would have an adverse effect on the RMB amount we would receive from the conversion. Conversely, if we decide to convert RMB into U.S. dollars for the purpose of making payments for dividends on our ordinary shares, strategic acquisitions or investments or other business purposes, appreciation of the U.S. dollar against RMB would have a negative effect on the U.S. dollar amount available to us.

In addition, a significant depreciation of the RMB against the U.S. dollar may significantly reduce the U.S. dollar equivalent of our receivables, earnings or losses.

Currency Convertibility Risk

        A majority of our expenses and Further, volatility in exchange rate fluctuations may have a significant portion of our assets and liabilities are denominated in RMB. On January 1, 1994,impact on the PRC government abolished the dual rate system and introduced a single rate of exchange as quoted daily by the People's Bank of China, or PBOC. However, the unification of exchange rates does not imply that the RMB may be readily convertible into U.S. dollars or other foreign currencies.

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as such term is(as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act.Act). Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principlesU.S. generally accepted in the United States of America.accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. In addition,Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, andor that the degree of compliance with the policies or procedures may deteriorate. Management assessed
Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our assessment and those criteria, management concluded that we maintained effective internal control over financial reporting as of December 31, 2019.
The effectiveness of our internal control over financial reporting as of December 31, 2016. In making2019, has been tested by Ernst & Young Hua Ming LLP, our independent registered public accounting firm, as stated in their report which is included in “Item 8—Financial Statements and Other Supplementary Data” in this assessment, management used the criteria set forth in the Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

Annual Report.

        Based on its assessment of internal control over financial reporting, our management, including our Chief Executive Officer and Chief Financial Officer have concluded that, as of December 31, 2016, our internal control over financial reporting was effective. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only assurance at a reasonable level with respect to the financial statement preparation and presentation.

Changes in Internal Control over Financial Reporting

        In connection with the audit of our consolidated financial statements for the years ended December 31, 2013, 2014 and 2015, we identified a material weakness in our internal control over financial reporting that related to having an insufficient number of financial reporting personnel with an appropriate level of knowledge, experience and training in application of GAAP and SEC rules and regulations commensurate with our reporting requirements.

        In 2016, we implemented measures designed to improve our internal control over financial reporting to remediate this material weakness, including the following:

        We believe that the measures taken above enhanced our internal control over financial reporting and

There were sufficient to remediate the material weakness identified. Our independent registered public accounting firm will first be required to attest to the effectiveness of our internal control over financial reporting for our Annual Report on Form 10-K for the first year we are no longer an EGC under the JOBS Act. There is no guarantee that our remediation efforts will result in the attestation from our independent registered public accounting firm, if required, that our internal control over financial reporting is effective as of December 31, 2017.

        Except as described above, there were no other changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d)13a‑15(d) and 15d-15(d)15d‑15(d) of the Exchange Act that occurred during the three months ended December 31, 20162019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of BeiGene, Ltd. (the "Company")Company) as of December 31, 20162019 and 2015, and2018, the related consolidated statements of operations, comprehensive loss, cash flows and shareholders' equity (deficit) for each of the three years in the period ended December 31, 2016. 2019, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2019, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated March 2, 2020 expressed an unqualified opinion thereon.

Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, referredtaken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to above present fairly,which it relates.

Accrual of research and development expenses
Description of the Matter
During the year ended December 31, 2019, the Company recognized $927.3 million in research and development (“R&D”) expenses. The balance of accrued external R&D activities related expenses as of December 31, 2019 amounted to approximately $62.8 million. As described in Note 2 to the consolidated financial statements, R&D expenses primarily include costs related to clinical trials and preclinical testing paid to third-party contract research organizations and contract manufacturing organizations (collectively referred as “Outsourced Service Providers”).
Auditing the accrual of R&D expenses related to Outsourced Service Providers is complex because billing terms under contracts with Outsourced Service Providers often do not coincide with the timing of when the work is performed, which in turn requires management to make estimates of outstanding obligations as of period end. These estimates are based on a number of factors, including management’s knowledge of the R&D programs and activities associated with timelines, invoicing to date, and the provisions in the contracts. Significant management judgments and estimates are required in determining the accrued balances at the end of any reporting period and changes in those estimates can have a material effect on the amount of R&D expenses recognized. This in turn led to significant auditor judgment, subjectivity and effort in performing procedures to evaluate audit evidence for these estimates.
How We Addressed the Matter in Our Audit
We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the accrual of the R&D expenses. For example, we tested controls over management's review of the R&D accrual method and the estimates of the actual services performed by the Outsourced Service Providers.
To test the accrual of R&D expenses, our audit procedures included, among others, reading the contracts with Outsourced Service Providers on a sample basis and understanding and testing management’s process for developing estimates based on the progress of the R&D activities. Testing management’s process for developing the accrual estimates involved evaluating the reasonableness of the assumptions used in the calculation related to the R&D programs and associated timelines, invoicing to date and the provisions in the contracts. We then evaluated the adequacy of the accrual of R&D expenses by comparing it to the subsequent progress billings issued by the Outsourced Service Providers. We also assessed the appropriateness of the accrual method used by the Company in accordance with U.S. generally accepted accounting principles, including the adequacy of related disclosures in the consolidated financial statements.

Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in conformitythe accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Significant Accounting Policies

Basis of presentationPresentation and principlesPrinciples of consolidation

Consolidation

The consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP"(“GAAP”). The consolidated financial statements include the financial statements of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances between the Company and its wholly-owned subsidiaries are eliminated upon consolidation.

Noncontrolling interests are recognized to reflect the portion of the equity of subsidiaries which are not attributable, directly or indirectly, to the controlling shareholders. The Company consolidates its interests in its joint ventures, BeiGene Biologics and MapKure, LLC, under the voting model and recognizes the minority shareholders' equity interest as a noncontrolling interest in its consolidated financial statements.
Use of estimates

Estimates

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period. Areas where management uses subjective judgment include, but are not limited to, estimating the useful lives of long-lived assets, estimating variable consideration in product sales and collaboration revenue arrangements, identifying separate accounting units and estimating the best estimate ofstandalone selling price of each deliverableperformance obligation in the Company'sCompany’s revenue arrangements, estimating the fair value of net assets acquired in business combinations, assessing the impairment of long-lived assets,

share-based compensation expenses, realizability of deferred tax assets, estimating uncertain tax positions, measurement of right-of-use assets and lease liabilities and the fair value of financial instruments. Management bases the estimates on historical experience, known trends and various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from these estimates.

Functional Currency and Foreign Currency Translation

Foreign currency of the Company, BeiGene AUS Pty Ltd., BeiGene (Hong Kong) Co., Limited, BeiGene 101 Ltd and BeiGene (USA) is the United States dollar ("$" or "U.S. dollar"). The Company's PRC subsidiaries determined their functional currencies to be RMB. The Company uses the U.S. dollar as its reporting currency.

Foreign Currency Translation

translation

For subsidiaries whose functional currencies are not the U.S. dollar, the Company uses the average exchange rate for the year and the exchange rate at the balance sheet date, to translate the operating results and financial position to U.S. dollar, the reporting currency, respectively. Translation differences are recorded in accumulated other comprehensive income/(loss),loss, a component of shareholders' equity/deficit.shareholders’ equity. Transactions denominated in currencies other than the functional currency are translated into the functional currency at the exchange rates prevailing on the transaction dates. Foreign currency denominated financial assets and liabilities are remeasured at the exchange rates prevailing at the balance sheet date. Exchange gains and losses are included in the consolidated statements of comprehensive loss.

Cash, Cash Equivalents and Restricted Cash
Cash and cash equivalents

Cash and cash equivalents consist of cash on hand and bank deposits, which are unrestricted as to withdrawal and use. The Company considers all highly liquid investments with an original maturity date of three months or less at the date of purchase to be cash equivalents. Cash equivalents which consist primarily of money market funds are stated at fair value.

Short-term investments

Restricted cash
Restricted cash primarily consists of RMB-denominated cash deposits pledged in designated bank accounts as collateral for bank loans and letters of credit. The Company classifies restricted cash as current or non-current based on the term of the restriction.
Accounts Receivable
Trade accounts receivable are recorded at their invoiced amounts, net of trade discounts and allowances as well as allowances for doubtful accounts. An allowance for doubtful accounts is recorded when the collection of the full amount is no longer probable. In evaluating the collectability of receivable balances, the Company considers specific evidence including aging of the receivable, the customer's payment history, its current creditworthiness and current economic trends. Accounts receivable are written off after all collection efforts have ceased. The Company regularly reviews the adequacy and appropriateness of any allowance for doubtful accounts. NaN allowance for doubtful accounts was recorded as of December 31, 2019.
Inventory
Prior to the regulatory approval of product candidates, the Company may incur expenses for the manufacture of drug product to support the commercial launch of those products. Until the date at which regulatory approval has been received or is otherwise considered probable, all such costs are recorded as research and development expenses as incurred.
To date the Company's inventory has consisted entirely of finished goods inventory purchased from Celgene Logistics Sàrl, a Bristol-Myers Squibb company ("BMS"). Inventories are stated at the lower of cost and net realizable value, with cost determined on a weighted-average basis. The Company periodically analyzes its inventory levels, and writes down inventory that has become obsolete, inventory that has a cost basis in excess of its estimated realizable value and inventory in excess of expected sales requirements as cost of product sales. The determination of whether inventory costs will be realizable requires estimates by management. If actual market conditions are less favorable than projected by management, additional write-downs of inventory may be required, which would be recorded in the consolidated statements of operations. There have been no write-downs or reserves against inventory to date.
Short-Term Investments
Investments with original maturities of greater than three months at the date of purchase and less than one year from the date of the balance sheet are classified as short-term. Short-term debt investments held to maturity are carried at amortized cost when the Company has the ability and positive intent to hold these securities until maturity. When the Company does not have the ability or positive intent to hold short-term debt investments until maturity, these securities are classified as available-for-sale. None of the Company'sCompany’s fixed maturity securities met the criteria for held-to-maturity classification at December 31, 20162019 and 2015.

available-for-sale is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization is computed using the effective interest method and included in interest income. Interest and dividends are included in interest income.

When the fair value of a debt security classified as available-for-sale is less than its amortized cost, the Company assesses whether or not: (i) it has the intent to sell the security or (ii) it is more likely than not that the Company will be required to sell the security before its anticipated recovery. If either of these conditions is met, the Company must recognize an other-than-temporary impairment through earnings for the difference between the debt security'ssecurity’s amortized cost basis and its fair value. No impairment losses were recorded for any periods presented.

The cost of securities sold is based on the specific identification method.

Property and Equipment

Property and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets as follows:


Useful Life
Office Equipment 5Useful Life
Building20 years
Electronic EquipmentManufacturing equipment3 to 10 years
Laboratory Equipment3 to 5 years
Computer Software, Electronic and Office Equipment3 to 5 years
Leasehold ImprovementsLesser of useful life or lease term

Leases
Effective January 1, 2019, the Company adopted Accounting Standards Codification, Topic 842, Leases ("ASC 842") using the effective date method. The Company determines if an arrangement is a lease at inception. The Company has lease agreements with lease and non-lease components, which are accounted for as a single lease component based on the Company’s policy election to combine lease and non-lease components for its leases. Leases are classified as operating or finance leases in accordance with the recognition criteria in ASC 842-20-25. The Company’s lease portfolio consists entirely of operating leases as of December 31, 2019. The Company’s leases do not contain any material residual value guarantees or material restrictive covenants.
At the commencement date of a lease, the Company determines the classification of the lease based on the relevant factors present and records a right-of-use ("ROU") asset and lease liability. ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. ROU assets and lease liabilities are calculated as the present value of the lease payments not yet paid. Variable lease payments not dependent on an index or rate are excluded from the ROU asset and lease liability calculations and are recognized in expense in the period which the obligation for those payments is incurred. As the rate implicit in the Company’s leases is not typically readily available, the Company uses an incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. This incremental borrowing rate reflects the fixed rate at which the Company could borrow on a collateralized basis the amount of the lease payments in the same currency, for a similar term, in a similar economic environment. ROU assets include any lease prepayments and are reduced by lease incentives. Operating lease expense for lease payments is recognized on a straight-line basis over the lease term. Lease terms are based on the non-cancelable term of the lease and may contain options to extend the lease when it is reasonably certain that the Company will exercise that option.
Operating leases are included in operating lease right-of-use assets and lease liabilities on the consolidated balance sheet. Lease liabilities that become due within one year of the balance sheet date are classified as current liabilities.
Leases with an initial lease term of 12 months or less are not recorded on the consolidated balance sheet. Lease expense for these leases is recognized on a straight-line basis over the lease term.

Land Use Right, Net
All land in the PRC is owned by the PRC government. The PRC government may sell land use rights for a specified period of time. Land use rights represent operating leases in accordance with ASC 842. The purchase price of land use rights represents lease prepayments to the PRC government and is recorded as an operating lease ROU asset on the balance sheet. The ROU asset is amortized over the remaining lease term.
In 2017, the Company acquired a land use right from the local Bureau of Land and Resources in Guangzhou for the purpose of constructing and operating the biologics manufacturing facility in Guangzhou.  In 2019, the Company acquired a second Guangzhou land use right from the local Bureau of Land and Resources in Guangzhou. Both Guangzhou land use rights are being amortized over the respective terms of the land use rights, which are each 50 years. 
In 2018, the Company acquired a land use right in conjunction with the Innerway asset acquisition (see Note 4). The land use right is being amortized over the term of the land use right, which is 36 years.
Business Combinations
The Company accounts for its business combinations using the acquisition method of accounting in accordance with ASC topic 805 (“ASC 805”): Business Combinations. The acquisition method of accounting requires all of the following steps: (i) identifying the acquirer, (ii) determining the acquisition date, (iii) recognizing and measuring the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree, and (iv) recognizing and measuring goodwill or a gain from a bargain purchase. The consideration transferred in a business combination is measured as the aggregate of the fair values at the date of exchange of the assets given, liabilities incurred, and equity instruments issued as well as the contingent considerations and all contractual contingencies as of the acquisition date. 
The costs directly attributable to the acquisition are expensed as incurred. Identifiable assets, liabilities and contingent liabilities acquired or assumed are measured separately at their fair value as of the acquisition date, irrespective of the extent of any noncontrolling interests. The excess of (i) acquisition consideration, fair value of the noncontrolling interests and acquisition date fair value of any previously held equity interest in the acquiree over (ii) the fair value of the identifiable net assets of the acquiree, is recorded as goodwill. If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognized directly in the consolidated statements of operations as a gain.
The Company allocates the fair value of purchase consideration to the tangible assets acquired, liabilities assumed and intangible assets acquired based on their estimated fair values. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets may include, but are not limited to, future expected cash flows from acquired assets, timing and probability of success of clinical events and regulatory approvals, and assumptions on useful lives and discount rates. Management's estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. Additional information, such as that related to income tax and other contingencies, existing as of the acquisition date but unknown to us may become known during the remainder of the measurement period, not to exceed one year from the acquisition date, which may result in changes to the amounts and allocations recorded.
Acquisitions that do not meet the accounting definition of a business combination are accounted for as asset acquisitions. For transactions determined to be asset acquisitions, the Company allocates the total cost of the acquisition, including transaction costs, to the net assets acquired based on their relative fair values.
Goodwill and Other Intangible Assets
Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. The Company allocates the cost of an acquired entity to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The excess of the purchase price for acquisitions over the fair value of the net assets acquired, including other intangible assets, is recorded as goodwill. Goodwill is not amortized, but is tested for impairment at least annually or more frequently if events or changes in circumstances would indicate a potential impairment.

(Amounts in thousands of U.S. Dollar (“$”) and Renminbi (“RMB”),
except for number of shares and per share data)


The Company has elected to first assess qualitative factors to determine whether it is more likely than not that the fair value of the Company's reporting unit is less than its carrying amount, including goodwill. The qualitative assessment includes the Company's evaluation of relevant events and circumstances affecting the Company's single reporting unit, including macroeconomic, industry, and market conditions, the Company's overall financial performance, and trends in the market price of the Company's ADSs. If qualitative factors indicate that it is more likely than not that the Company's reporting unit’s fair value is less than its carrying amount, then the Company will perform the quantitative impairment test by comparing the reporting unit’s carrying amount, including goodwill, to its fair value. If the carrying amount of the reporting unit exceeds its fair value, an impairment loss will be recognized in an amount equal to that excess. For the years ended December 31, 2019, 2018 and 2017 the Company determined that there were no indicators of impairment of goodwill.
Intangible assets acquired through business combinations are recognized as assets separate from goodwill and are measured at fair value upon acquisition. Intangible assets acquired in transactions that are not business combinations are recorded at the allocated portion of total consideration transferred based on their relative fair value in relation to net assets acquired. Acquired identifiable intangible assets consist of distribution rights for approved cancer therapies licensed from BMS, ABRAXANE®, REVLIMID®, and VIDAZA®, and are amortized on a straight-line basis over the estimated useful lives of the assets, which is 10 years, and the trading license which represents the Guangzhou drug distribution license acquired on September 21, 2018 (see Note 4). The Company is amortizing the trading license over the remainder of the license term through February 2020.
Intangible assets with finite useful lives are tested for impairment when events or circumstances occur that could indicate that the carrying amount of an asset may not be recoverable. When these events occur, the Company evaluates the recoverability of the intangible assets by comparing the carrying amount of the assets to the future undiscounted cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flows is less than the carrying amount of the assets, the Company recognizes an impairment loss based on the excess of the carrying amount of the assets over their fair value. Fair value is generally determined by discounting the cash flows expected to be generated by the assets, when the market prices are not readily available. For the years ended December 31, 2019, 2018 and 2017, the Company determined that there were 0 indicators of impairment of its other intangible assets.
Impairment of long-lived assets

Long-Lived Assets

Long-lived assets are reviewed for impairment in accordance with authoritative guidance for impairment or disposal of long-lived assets. Long-lived assets are reviewed for events or changes in circumstances, which indicate that their carrying value may not be recoverable. Long-lived assets are reported at the lower of carrying amount or fair value less cost to sell. For the years ended December 31, 2016, 20152019, 2018 and 2014,2017, there was no0 impairment of the value of the Company'sCompany’s long-lived assets.

On the exercise dates, the Company determined the fair values of the warrants and option liabilities using the intrinsic value, which equals to the difference between the share price at the IPO closing date and the exercise price, as the exercise dates were immediately prior to or very close to the IPO closing date.

The Company applies ASC topic 820 ("(“ASC 820"820”),Fair Value Measurements and Disclosures, in measuring fair value. ASC 820 defines fair value, establishes a framework for measuring fair value and requires disclosures to be provided on fair value measurement. ASC 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level 1—Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2—Include other inputs that are directly or indirectly observable in the marketplace.

Level 3—Unobservable inputs which are supported by little or no market activity.

ASC 820 describes three main approaches to measuring the fair value of assets and liabilities: (1)market approach; (2) income approach and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required to replace an asset.

Revenue Recognition
Effective January 1, 2018, the Company adopted Accounting Standards Codification, Topic 606, Revenue from Contracts with Customers (“ASC 606”) using the modified retrospective method.
Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price, including variable consideration, if any; (iv) allocate the transaction price to the performance obligations in the contract; and option fair value estimation on(v) recognize revenue when (or as) the exercise dates

2. Summary



Once a contract is determined to be within the scope of significant accounting policies (Continued)

inputs usedASC 606 at contract inception, the Company reviews the contract to determine which performance obligations it must deliver and which of these performance obligations are distinct. The Company recognizes as revenue the amount of the transaction price that is allocated to each performance obligation when that performance obligation is satisfied or as it is satisfied.

Product revenue
The Company's product revenues are generated from the sale of ABRAXANE, REVLIMID, and VIDAZA to its product distributor in China, the Company's sole customer in China. The first tier distributor subsequently resells the products to second tier distributors who ultimately sell the products to health care providers and patients. Following FDA approval on November 14, 2019, the Company began selling its first internally developed drug, BRUKINSA, in the fair value measurementUnited States to specialty pharmacies and specialty distributors, the corresponding impactsCompany's U.S. customers. The specialty pharmacies and specialty distributors subsequently resell the product to health care providers and patients. The Company is the principal under the product sales as the Company controls the products with the ability to direct the use of, and obtain substantially all the remaining benefits from the products before they are sold to the fair valuescustomer. For product sales transactions, the Company has a single performance obligation which is to sell the products to its customer. The Company includes variable consideration in the transaction price to the extent it is probable that a significant reversal will not occur and estimates variable consideration from rebates, chargebacks, trade discounts and allowances, sales returns allowances and other incentives using the expected value method. Revenues for product sales are presented below:

recognized at a point in time when the single performance obligation is satisfied upon delivery to the customer. The Company's payment terms are approximately 60-90 days. Actual amounts of consideration ultimately received may differ from the Company’s estimates. The Company will reassess estimates for variable consideration periodically. If actual results in the future vary from the Company’s estimates, the Company will adjust these estimates, which would affect net product revenue and earnings in the period such variances become known.

In China, rebates, including price compensation credits, are offered to distributors, consistent with pharmaceutical industry practices. The following tables presentCompany records a reconciliationprovision for rebates at the time of sale based on contracted rates and historical redemption rates. Assumptions used to establish the provision include the level of distributor inventories, sales volumes and contract pricing and estimated acceptance of government pricing or reimbursement amounts (such as provincial acceptance of the warrantsNational Reimbursement Drug List pricing in the PRC). The Company regularly reviews the information related to these estimates and option liabilitiesadjusts the provision accordingly.

In the United States, estimates for variable consideration for which reserves are established at the time of sale include government rebates, chargebacks, trade discounts and allowances, sales returns allowances and other incentives that are offered within contracts between the Company and its US customers, health care providers and other indirect customers. Where appropriate, these estimates take into consideration a range of possible outcomes that are probability-weighted for relevant factors such as our historical experience, current contractual and statutory requirements, specific known market events and trends, industry data and forecasted customer buying and payment patterns. U.S. product revenues and related reserves for variable consideration were not significant for the yearsyear ended December 31, 2016.

2019 as the Company did not begin generating product revenue in the United States until after BRUKINSA received FDA approval on November 14, 2019.
The Company bases its sales returns allowance on estimated distributor inventories, customer demand as reported by third-party sources, and actual returns history, as well as other factors, as appropriate. For newly launched products where actual returns history is not yet available, the sales returns allowance is initially calculated based on benchmarking data from similar products and industry experience. If the historical or benchmarking data the Company uses to calculate these estimates do not properly reflect future returns, then a change in the allowance would be made in the period in which such a determination is made and revenues in that period could be materially affected. Any changes from the historical trend rates are considered in determining the current sales return allowance. To date, sales returns have not been significant.
Collaboration revenue
At contract inception, the Company analyzes its collaboration arrangements to assess whether they are within the scope of ASC 808, Collaborative Arrangements (“ASC 808”) to determine whether such arrangements involve joint operating activities performed by parties that are both active participants in the activities and exposed to significant risks and rewards dependent on the commercial success of such activities. For collaboration arrangements within the scope of ASC 808 that contain multiple elements, the Company first determines which elements of the collaboration are deemed to be within the scope of ASC 808 and those that are more reflective of a vendor-customer relationship and therefore within the scope of ASC 606.

Revenue recognition

five-step model under ASC 606 noted above.

The Company recognizes revenues from research and development collaborative arrangements when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the fee is fixed or determinable, and there is reasonable assurance that the related amounts are collectible in accordance with ASC 605,Revenue Recognition ("ASC 605"). The Company'sCompany’s collaborative arrangements may contain multiple elements,more than one unit of account, or performance obligation, including grants of licenses to intellectual property rights, agreement to provide research and development services and other deliverables. The deliverables under such arrangements are evaluated under ASC 605-25,Multiple-Element Arrangements. Pursuant to ASC 605-25, each required deliverable is evaluated to determine whether it qualifies as a separate unit of accounting based on whether the deliverable has "stand-alone value" to the customer. The collaborative arrangements do not include a right of return for any deliverable. The arrangement's considerationAs part of the accounting for these arrangements, the Company must develop assumptions that is fixed or determinable, excluding contingent payments, is then allocatedrequire judgment to each separate unit of accounting based ondetermine the relative selling price of each deliverable. The relativestand-alone selling price for each deliverable is determined using vendor specific objective evidence ("VSOE") ofperformance obligation identified in the contract. In developing the stand-alone selling price or third party evidence ("TPE") of selling price if VSOE does not exist. If neither VSOE nor TPE exists,for a performance obligation, the Company uses the best estimateconsiders competitor pricing for a similar or identical product, market awareness of and perception of the selling price ("BESP") for the deliverable.product, expected product life and current market trends. In general, the consideration allocated to each unit of accountingperformance obligation is recognized aswhen the related goodsrespective obligation is satisfied either by delivering a good or services are delivered,providing a service, limited to the consideration that is not contingent upon future deliverables.constrained. Non-refundable payments received before all of the relevant criteria for revenue recognition are satisfied are recorded as advances from customers.

Licenses of Intellectual Property: Upfront non-refundable payments for licensing the Company'sCompany’s intellectual property are evaluated to determine if the licensee can obtain stand-alone valuelicense is distinct from the other performance obligations identified in the arrangement. For licenses determined to be distinct, the Company recognizes revenues from non-refundable, up-front fees allocated to the license separateat a point in time, when the license is transferred to the licensee and the licensee is able to use and benefit from the valuelicense.  
Research and Development Services: The portion of the transaction price allocated to research and development services and other deliverables in the arrangement to be provided by the Company. The Company acts as the principal under its arrangements and licensing intellectual propertyperformance obligations is part of its ongoing major or central operations. The license right is not contingent upon the delivery of additional items or meeting other specified performance conditions. Therefore, when stand-alone value of the license is determinable, the allocated consideration isdeferred and recognized as collaboration revenue upon delivery of the license rights.

        As the Company actsover time as the principal under its arrangements, and research and development services are also part of its ongoing major or central operations, it recognizes the allocated consideration related to reimbursements of research and development costs as collaboration revenue when delivery or performance of such services occurs.

        Product R&D reimbursement revenue for revenue attributable to the clinical trials that BMS had opted into is recognized as delivery or performance of such services occurs.

Milestone Payments: At the inception of each arrangement that includes development royaltiesmilestone payments, the Company evaluates whether the milestones are considered probable of being reached and commercial event payments (collectively, "target payments") under collaborative arrangements are triggered either byestimates the results of the Company's research and development efforts, achievement of regulatory goals or by specified sales results by a third party

The Company will assess whether the Company would account for development-based targets as collaboration revenue upon achievement of the respective development target. Royaltiesvariable consideration is fully constrained each reporting period based on reported sales of licensed productsthe facts and circumstances surrounding the clinical trials. Upon changes to constraint associated with the developmental milestones, variable consideration will be recognized as collaboration revenue based on contract terms when reported sales are reliably measurable and collectability is reasonably assured. Targets related to commercial activities may be triggered upon events such as first commercial sale of a product or when sales first achieve a defined level. Since these targets would be achieved after the completion of the Company's development activities, the Company would account for the commercial event targetsincluded in the same manner as royalties, with collaborationtransaction price when a significant reversal of revenue recognized upon achievement of the target.

Regulatory milestones are fully constrained until the period in which those regulatory approvals are achieved due to the inherent uncertainty with the approval process. Regulatory milestones are included in the transaction price in the period regulatory approval is obtained.

The fair value of restricted shares and restricted share units are based on the closing market price of our ADSs on the NASDAQ Global Select Market on the date of grant. The Company has elected to recognize compensation expense using the straight-line method for all employee equity awards granted with graded vesting based on service conditions provided that the amount of compensation cost recognized at any date is at least equal to the portion of the grant-date value of the options that are vested at that date. The Company uses the accelerated method for all awards granted with graded vesting based on performance conditions.

ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in the subsequent period if actual forfeitures differ from initial estimates.

Forfeiture rates are estimated based on historical and future expectations of employee turnover rates and are adjusted to reflect future changes in circumstances and facts, if any.

Awards granted to non-employees

The Company has accounted for equity instruments issued to non-employees in accordance with the provisions of ASC 718 and ASC 505,Equity. Equity. All transactions in which goods or services are received in exchange for equity instruments are accounted for based on the fair value of the consideration received or the fair value of the equity instrument issued, whichever is more reliably measurable.

Modification of awards

A change in any of the terms or conditions of the awards is accounted for as a modification of the award. Incremental compensation cost is measured as the excess, if any, of the fair value of the modified award over the fair value of the original award immediately before its terms are modified, measured based on the fair value of the awards and other pertinent factors at the modification date. For vested awards, the Company recognizes incremental compensation cost in the period the modification occurs. For unvested awards, the Company recognizes over the remaining requisite service period, the sum of the incremental compensation cost and the remaining unrecognized compensation cost for the original award on the modification date. If the fair value of the modified award is lower

than the fair value of the original award immediately before modification, the minimum compensation cost the Company recognizes is the cost of the original award.

Derivative instruments

        ASC 815,Derivatives and Hedging, requires all contracts which meet the definition of a derivative to be recognized in the consolidated financial statements as either assets or liabilities and recorded at fair value. Changes in the fair value of derivative financial instruments are either recognized periodically in income/loss or in shareholders' deficit as a component of other comprehensive income depending on the use of the derivative and whether it qualifies for hedge accounting. Changes in fair values of derivatives not qualified as hedges are reported in the consolidated statements of operations. The estimated fair values of derivative instruments are determined at discrete points in time based on the relevant market information. These estimates are calculated with reference to the market rates using industry standard valuation techniques with the assistance of an independent third party valuation firm.

Income taxes

Taxes

The Company uses the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and the tax bases of assets and liabilities and are measured using enacted tax rates and laws that will be in effect when the differences are expected to reverse. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized.

        In November 2015, the FASB issued Accounting Standards Update 2015-17,Balance Sheet Classification of Deferred Taxes, which requires deferred income tax assets and liabilities to be classified as non-current in a classified balance sheet, and eliminates the prior guidance, which required an entity to separate deferred tax assets and liabilities into a current amount and a non-current amount in a classified balance sheet. The Company changed the manner in which it classifies deferred tax assets and liabilities retrospectively from the fourth quarter of 2016 due to the early adoption of Accounting Standards Update 2015-17. The adoption of this guidance has no impact on prior year balances as current deferred tax assets and liabilities are both nil as of December 31, 2015.

The Company evaluates its uncertain tax positions using the provisions of ASC 740,Income Taxes,, which requiresprescribes a recognition threshold that realization of an uncertain incomea tax position beis required to meet before being recognized in the financial statements. The benefit to be recordedCompany recognizes in the financial statements the benefit of a tax position which is the amount most“more likely than not” to be realizedsustained under examination based solely on the technical merits of the position assuming a review by tax authorities having all relevant information and applying current conventions.information. Tax positions that meet the recognition threshold are measured using a cumulative probability approach, at the largest amount of tax benefit that has a greater than fifty percent likelihood of being realized upon settlement. It is the Company'sCompany’s policy to recognize interest and penalties related to unrecognized tax benefits, if any, as a component of income tax expense.

However, both the convertible preferredrestricted shares and restricted stock do not have contractual rights and obligations to share in the losses of the Company. For the periods presented herein, the computation of basic loss per share using the two-class method is not applicable as the Company is in a net loss position.

Diluted loss per share is calculated by dividing net loss attributable to ordinary shareholders as adjusted for the effect of dilutive ordinary equivalent shares, if any, by the weighted average number of ordinary and dilutive ordinary equivalent shares

Concentration of credit risk

Financial instruments that are potentially subject to credit risk consist of cash and cash equivalents and short-term investments. The carrying amounts of cash and cash equivalents and short-term investments represent the maximum amount of loss due to credit risk. As of December 31, 20162019 and 2015, $87,5142018, $618,011 and $17,869$712,937 were deposited with various major reputable financial institutions located in the PRC and international financial institutions outside of the PRC.

Business, customer, political, social and economic risks

The Company participates in a dynamic high technologybiopharmaceutical industry and believes that changes in any of the following areas could have a material adverse effect on the Company'sCompany’s future financial position, results of operations or cash flows: changes in the overall demand for services and products; competitive pressures due to new entrants; advances and new trends in new technologiesdrugs and industry standards; changes in clinical research organizations;organizations, contract manufacturers and other key vendors; changes in certain strategic relationships or customer relationships; regulatory considerations; copyright regulations;intellectual property considerations; and risks associated with the Company'sCompany’s ability to attract and retain employees necessary to support its growth. The Company'sCompany’s operations could be also adversely affected by significant political, economic and social uncertainties in the PRC.

Currency convertibility risk

A majority of the Company's expenses and a significant portion of the Company'sCompany’s expenses, assets and liabilities are denominated in RMB. On January 1, 1994, the PRC government abolished the dual rate system and introduced a single rate of exchange as quoted daily by the People'sPeople’s Bank of China (the "PBOC"“PBOC”). However, the unification of the exchange rates does not imply that the RMB may be readily convertible into U.S. dollar or other foreign currencies. All foreign exchange transactions continue to take place either through the PBOC or other banks authorized to buy and sell foreign currencies at the exchange rates quoted by the PBOC. Approvals of foreign currency payments by the PBOC or other institutions require submitting a payment application form together with suppliers'suppliers’ invoices, shipping documents and signed contracts.

Additionally, the value of the RMB is subject to changes in central government policies and international economic and political developments affecting supply and demand in the PRC foreign exchange trading system market.

To the extent that the Company needs to convert U.S. dollar into RMB for capital expenditures and working capital and other business purposes, appreciation of RMB against U.S. dollar would have an adverse effect on the RMB amount the Company would receive from the conversion. Conversely, if the Company decides to convert RMB into U.S. dollar for the purpose of making payments for dividends on ordinary shares, strategic acquisitions or investments or other business purposes, appreciation of U.S. dollar against RMB would have a negative effect on the U.S. dollar amount available to the Company. In addition, a significant depreciation of the RMB against the U.S. dollar may significantly reduce the U.S. dollar equivalent of the Company'sCompany’s earnings or losses.

2. Summary of significant accounting policies (Continued)

        In February 2016, the FASB issued ASU No. 2016-02,Leases, which requiresrequire lessees to recognize assets and liabilities related to lease arrangements longer than 12 months on the balance sheet. This standard also requires additional disclosures by lessees and contains targeted changes to accounting by lessors. The updated guidance iswas effective for interim and annual periods beginning after December 15, 2018, andwith early adoption is permitted. Leases will be classified as finance or operating, with the classification affecting the pattern and classification of expense recognition. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee have not significantly changed from previous GAAP. A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial adoption. The guidance permits entities to choose to use either its effective date or the beginning of the earliest period presented in the financial statements as its date of initial application.

The Company is currently evaluatingadopted the new standard effective January 1, 2019 using the effective date method and did not restate comparative periods. The Company elected the package of practical expedients permitted under the transition guidance within the new standard, which permits the Company not to reassess under the new standard its prior conclusions about lease identification, lease classification and initial direct costs. Upon adoption, the Company recognized a lease liability of $27,446, with corresponding ROU assets of $25,978 based on the present value of the remaining minimum rental payments under existing operating leases. The difference between the lease liability and right-of-use asset relates to the reversal of existing deferred rent and prepaid rent balances of $1,739 and $271, respectively. Additionally, the Company reclassified its land use rights of $45,058 to ROU assets upon adoption. The adoption of the standard did not impact on its financialthe Company’s consolidated statements of adopting this guidance.

Celgene Corporation, a Bristol-Myers Squibb company ("BMS")
On July 5, 2017, the Company entered into a license agreement with Celgene Corporation, now BMS, pursuant to which the Company granted to the BMS parties an exclusive right to develop and commercialize the Company’s investigational PD-1 inhibitor, tislelizumab, in all fields of treatment, other than hematology, in the United States, Europe, Japan and the rest of world other than Asia (the “PD-1 License Agreement”). In connection with the closing of the transactions on August 31, 2017, the Company, and BMS amended and restated the PD-1 License Agreement (the “A&R PD-1 License Agreement”) to, among other things, clarify the parties’ responsibilities relating to the conducting and funding of certain global registration clinical trials and clarify the scope of the regulatory materials transferred by BeiGene to BMS. The Company entered into a mutual agreement with BMS to terminate the A&R PD-1 License Agreement effective June 14, 2019 in advance of the acquisition of Celgene by BMS.
Under the terms of the A&R PD-1 License Agreement, BMS paid the Company $263,000 in upfront non-refundable fees, of which $92,050 was paid in the third quarter of 2017 and the remaining $170,950 was paid in December 2017. The Company allocated $13,000 of upfront fees to the fair value of assets related to the Company’s acquisition of Celgene Shanghai, a wholly-

owned subsidiary of Celgene Holdings East Corporation established under the laws of China, which was completed contemporaneously with the A&R PD-1 License Agreement. The Company was also eligible to receive product development and commercial milestone payments based on the successful achievement of development and regulatory and commercialization goals, respectively, and potential royalty payments.
In addition to the exclusive right to develop and commercialize tislelizumab, the terms of the A&R PD-1 License Agreement provided BMS with the right to collaborate with the Company on the development of tislelizumab for specified indications, including required participation on a joint development committee and a joint steering committee as well as a joint commercialization committee upon achievement of commercialization. BMS reimbursed the Company for certain research and development costs at a cost plus agreed upon markup for the development of tislelizumab related to the clinical trials that BMS opted into, as outlined in the development plan.
Under ASC 606, the Company identified the following deliverables of the collaboration agreement as distinct performance obligations:  (a) the license provided to BMS for the exclusive right to develop and commercialize tislelizumab, in all fields of treatment, other than hematology, in the United States, Europe, Japan and the rest of world other than Asia (“the license”); and (b) the research and development services provided to BMS to develop tislelizumab within specified indications (“R&D services”). For each deliverable, the Company determined the stand-alone selling price and allocated the non-constrained consideration of $250,000 to the units of accounting using the relative selling price method. The consideration allocated to the license was recognized upon transfer of the license to BMS at contract inception and the consideration allocated to the R&D services was deferred and recognized over the term of the respective clinical studies for the specified indications. The payments associated with the defined developmental, regulatory, and commercialization goals were considered variable consideration and were fully constrained at contract inception through the date of termination.
In connection with the termination in June 2019, the Company regained full global rights to tislelizumab and received a $150,000 payment from BMS. The payment was recognized as other collaboration revenue upon termination as the Company had no further performance obligations under the collaboration. Upon termination, the Company also recognized the remainder of the deferred revenue balance related to the upfront consideration allocated to research and development services at the time of the original collaboration. The Company's license from BMS to distribute the approved cancer therapies ABRAXANE, REVLIMID, and VIDAZAin China was not affected by the termination of the tislelizumab collaboration.
For the year ended December 31, 2019, the Company recognized collaboration revenue of $205,616 related to the BMS collaboration, which consisted of $27,634 of research and development reimbursement revenue for the trials that BMS had opted into through the termination of the collaboration agreement; $27,982 of research and development services revenue, which reflects the recognition of the remaining upfront consideration that was allocated to research and development services at the time of the collaboration and was recognized over the term of the respective clinical studies for the specified indications; and $150,000 of other collaboration revenue related to the payment received from BMS in connection with the termination of the collaboration agreement.
For the year ended December 31, 2018, the Company recognized collaboration revenue of $65,835 related to the BMS collaboration, which consisted of $56,776 of research and development reimbursement revenue for the trials that BMS had opted into and research and development services revenue of $9,059 from deferred revenue.
For the year ended December 31, 2017, the Company recognized $211,391 as license revenue within collaboration revenue in the Company’s consolidated statements of operations, and research and development revenue of $1,568 allocated from deferred revenue related to the BMS collaboration.
Merck KGaA, Darmstadt Germany
In 2013, the Company entered into a license agreement with Merck KGaA, Darmstadt Germany for lifirafenib, which was amended and restated in 2013 and 2015, in which it granted to Merck KGaA, Darmstadt Germany an exclusive license to develop, manufacture, and, in certain circumstances, commercialize lifirafenib outside of the PRC, and Merck KGaA Darmstadt Germany granted the Company an exclusive license to develop, manufacture and commercialize lifirafenib in the PRC (the “PRC Territory”). In March 2017, the Company regained the worldwide rights to lifirafenib after Merck KGaA, Darmstadt Germany informed the Company that it would not exercise a continuation option, and thus, the ex-PRC portion of the agreements terminated in their entirety, except for certain provisions that survived the termination. In December 2018, the Company received notice from Merck KGaA, Darmstadt Germany that Merck KGaA, Darmstadt Germany was terminating the PRC portion of the agreement. As a result of the termination, Merck KGaA, Darmstadt Germany's exclusive right of first negotiation to acquire exclusive commercialization rights under the lifirafenib RAF dimer program in the PRC was terminated and the Company is no longer required to pay Merck KGaA, Darmstadt Germany royalties on sales of lifirafenib in the PRC or entitled to receive future milestone payments from Merck KGaA, Darmstadt Germany for lifirafenib.

The name of Celgene Shanghai has been changed to BeiGene Pharmaceutical (Shanghai).
On July 5, 2017, BeiGene and a wholly-owned subsidiary of BMS entered into a license agreement pursuant to which BeiGene was granted the right to exclusively distribute and promote BMS's approved cancer therapies, ABRAXANE, REVLIMID, and VIDAZA (the “Distribution Rights”), in China excluding Hong Kong, Macau and Taiwan (the “China License Agreement”). The China License Agreement became effective on August 31, 2017, contemporaneously with the closing of the acquisition of Celgene Shanghai and the A&R PD-1 License Agreement. The Company subsequently assigned the China License Agreement to its wholly-owned subsidiary, BeiGene Switzerland.
The Company evaluated the acquisition of the Celgene Shanghai equity and the distribution rights acquired under ASU No. 2017-1, Business Combinations: Clarifying the Definition of a Business. Because substantially all of the value of the acquisition did not relate to a similar group of assets and the business contained both inputs and processes necessary to manage products and provide economic benefits directly to its owners, it was determined that the acquisition represents a business combination. Therefore, the transaction has been accounted for using the acquisition method of adoptionaccounting. This method requires that assets acquired and liabilities assumed in a business combination be recognized at their fair values as of the acquisition date.

See Note 20 for further discussion of the Share Subscription Agreement.
Determination of purchase price
The purchase price of Celgene Shanghai was calculated as $28,138, and was comprised of cash consideration of $4,532 and non-cash consideration of $23,606, related to the discount on ordinary shares issued to BMS in connection with the Share Subscription Agreement. The discount was a result of the increase in fair value of the Company’s shares between the fixed price of $59.55 per ADS in the Share Subscription Agreement and the fair value per ADS as of the date of issuance, August 31, 2017. The following summarizes the purchase price in the business combination (in thousands).

Current and prior year additions include assessment of U.S. federal and state tax credits and incentives. None of the unrecognized tax benefits as of December 31, 2019 would impact the consolidated income tax rate if ultimately recognized due to valuation allowances. The Company does not anticipate that the amount of existing unrecognized tax benefits will significantly change within the next 12 months. 
The Company has elected to record interest and penalties related to income taxes as a component of income tax expense. For the years ended December 31, 2019, 2018 and 2017, the Company's accrued interest and penalties, where applicable, related to uncertain tax positions were not material.
The Company conducts business in a number of tax jurisdictions and, as such, is required to file income tax returns in multiple jurisdictions globally. As of December 31, 2019, Australia tax matters are open to examination for the years 2013 through 2019, China tax matters are open to examination for the years 2014 through 2019, and U.S. federal tax matters are open to examination for years 2016 through 2019. Various U.S. states and other non-US tax jurisdictions in which the Company files tax returns remain open to examination for 2010 through 2019.
The company qualifies for the Technology Advanced Service Enterprises (“TASE”) and High and New Technology Enterprise (“HNTE”) status for certain subsidiaries in China, which expire at the end of 2021. The income tax benefits attributable to this status for the year ended December 31, 2019 is approximately $2,600 or less than $0.01 per share outstanding.
During the year ended December 31, 2019, the Company completed intra-group transfers of certain intangible assets in anticipation of potential commercialization which resulted in the establishment of deferred tax assets that were fully offset by valuation allowances.
As of December 31, 2019, the Company continues to assert indefinite reinvestment on the excess of the financial reporting bases over tax bases in the Company's investments in foreign subsidiaries. A deferred tax liability has not been established for the approximately $9,620 of cumulative undistributed foreign earnings. Determination of the unrecognized deferred tax liability is not practicable due to uncertainty regarding the remittance structure and overall complexity of the hypothetical calculation.

Option to purchase shares by rental deferral

        On September 1, 2012, in conjunction with a lease agreement of one of its premises, the Company granted the landlord an option to purchase the Company's ordinary shares (the "Option") in exchange for the deferral of the payment of one year's rental expense. The Option was a freestanding instrument and was recorded as a liability in accordance with ASC480,Distinguishing Liabilities from Equity. The Option was initially recognized at fair value with subsequent changes in fair value recorded in losses. Prior to the Company's IPO, the Company determined the fair value of the Option with the assistance of an independent third party valuation firm. On February 8, 2016, immediately prior to the Company's IPO, the landlord exercised the Option to purchase 1,451,586 ordinary shares of the Company. As the exercise date was the IPO closing date, the exercise date fair value of the Option of $2,540 was determined based on its intrinsic value, which equaled the difference between the share price at the IPO closing date and the exercise price of such purchased ordinary shares.

Accounting for Preferred Shares

        The Preferred Shares were classified as mezzanine equity as these convertible preferred shares were redeemable upon the occurrence of a conditional event (i.e. a Liquidation Transaction). The holders of the Preferred Shares had a liquidation preference and would not receive the same form of consideration upon the occurrence of the conditional event as the holders of the ordinary shares would.

This in-substance redemption feature does not require bifurcation because it is clearly and closely related to the debt host instrument andthat does not involves a substantial premium or discount. Since there is no conversion feature embedded in the underlying ordinary shares were not publicly traded nor readily convertible into cash. The contingent redemption options of the convertible preferred shares did not qualify for bifurcation accounting because the underlying ordinary shares were neither publicly traded nor readily convertible into cash.Shareholder Loan, no beneficial conversion feature was recorded.

On the commitment date of Series A Preferred Shares and Series A-2 Preferred Shares, the most favorable conversion price used to measure the beneficial conversion feature were $0.68 and $1.17, respectively. No beneficial conversion feature was recognized for the Series A Preferred Shares and Series A-2 Preferred Shares as the fair value per ordinary share at the commitment date were $0.28 and $0.47, respectively, which was less than the most favorable conversion price. The Company determined the fair value of ordinary shares with the assistance of an independent third party valuation firm.

        The Company concluded that the Preferred Shares were not redeemable, and it was not probable that the Preferred Shares would become redeemable because the likelihood of a Liquidation Transaction was remote. Therefore, no adjustment was made to the initial carrying amount of the Preferred Shares.

        On February 8, 2016, in connection with the completion of the IPO, all of the outstanding Preferred Shares were converted into 199,990,641 ordinary shares.

13. Research and development collaborative arrangements

        The Company has developed and controls certain technology and proprietary materials related to its proprietary BRAF inhibitor ("BRAF" or "BGB-283") and poly (ADP-ribose) polymerase inhibitor ("PARP" or "BGB-290"). Upon execution of the Collaborative Arrangements, the Company granted to Merck KGaA, Darmstadt Germany the exclusive right to develop and commercialize the BRAF and PARP inhibitors worldwide except the PRC ("Ex-PRC"). The Company has since retained the exclusive right to develop and commercialize the BRAF and PARP inhibitors in the PRC, as further described below.

        In 2013, the Company entered into a license agreement with Merck KGaA, Darmstadt Germany on the BRAF inhibitor, which was amended and restated in 2013 and 2015, in which it granted to Merck KGaA, Darmstadt Germany an exclusive license to development and manufacture the BRAF inhibitor in the ex-PRC Territory, and Merck KGaA Darmstadt Germany granted the Company an exclusive license to develop, manufacture and commercialize the BRAF inhibitor in the PRC Territory. Under the terms of the BRAF Collaborative Arrangements, the Company received an upfront non-refundable payment and upfront Phase 1 research and development fees in 2013. Upon the dosing of the 5th patient in 2014, the Company received an additional Phase 1 research and development fee. Subsequent to the completion of the Phase 1 research and development phase, the Company was eligible to receiveCompany’s net product development payments based on the successful achievement of development and regulatory goals, commercial event payments based on the successful achievement of commercialization goals, and royalty payments based on a predetermined percentage of Merck KGaA, Darmstadt Germany's aggregate annual net sales of all products in the Ex-PRC territories for a period not to exceed ten years from the date of the first commercial sale. In March 2017, the Company regained the worldwide rights to the BRAF inhibitor after Merck KGaA, Darmstadt Germany informed the Company that it will not exercise the Continuation Option, and thus, the ex-PRC BRAF Agreement has terminated in its entirety, except for certain provisions that will survive the termination. In addition, the Company is eligible for $14,000 of additional payments upon the successful achievement of pre-specified milestones in the PRC territory. In consideration for the licenses Merck KGaA, Darmstadt Germany grants to the Company, it will pay Merck KGaA, Darmstadt Germany a high single-digit royalty on aggregate annual net sales of BGB-283 products in PRC for a period not to exceed ten years from the date of the first commercial sale.

        In 2013, the Company entered into a license agreement with Merck KGaA, Darmstadt Germany on the PARP inhibitor, in which it granted to Merck KGaA, Darmstadt Germany an exclusive license

13. Research and development collaborative arrangements (Continued)

to development and manufacture the PARP inhibitor in the ex-PRC Territory, and Merck KGaA Darmstadt Germany granted the Company an exclusive license to develop, manufacture and commercialize the PARP inhibitor in the PRC Territory. Under the terms of the PARP Collaborative Arrangements, the Company has received an upfront non-refundable payment and upfront Phase 1 research and development fees in 2013. Upon the dosing of the 5th patient in 2014, the Company received an additional Phase 1 research and development fee. On October 1, 2015, the Company entered into a purchase of rights agreement with Merck KGaA, Darmstadt Germany, pursuant to which the Company purchased from Merck KGaA, Darmstadt Germany all its exclusive rights to develop and commercialize the PARP inhibitors in the Ex-PRC territories for a consideration of $10,000, and reduced the future milestone payments the Company is eligible to receive under the PRC license agreement. Upon the execution of the purchase of rights agreement, Merck KGaA, Darmstadt Germany has no further rights and obligations in the Ex-PRC territories under the PARP Collaborative Agreements. In connection with such purchase of rights, the Company also provided Merck KGaA, Darmstadt Germany with global access to the Company's PARP supplies for Merck KGaA, Darmstadt Germany's combination clinical trials at any time during the period from October 1, 2015 until the first regulatory approval received for the commercialization of the Company's PARP inhibitor in certain major countries.

        The Company determined that the deliverables related to the collaboration with Merck KGaA, Darmstadt Germany, including the licenses of exclusive rights granted to Merck KGaA, Darmstadt Germany, as well as the Company's performance obligations to provide Phase 1 research and development services, would be accounted for as separate units of accounting. This determination was made because each deliverable has stand-alone value to Merck KGaA, Darmstadt Germany and the arrangement does not include a right of return for any deliverable. The Company recognized the upfront non-refundable license fee upon the delivery of the license right and the reimbursement of the Phase 1 research and development services on a straight-line basis over the performance period ranging from one to three years from the execution date of the respective collaboration arrangements. The Company has made an allocation of revenue recognized as collaboration revenue between the license and the services. This allocation was based upon the relative selling price determined using the BESP of each deliverable. Management utilized a discounted cash-flow model and considered a variety of factors in determining the best estimate of selling price of each deliverable, including, but not limited to: the rights that Merck KGaA, Darmstadt Germany was granted under the license, the early stage of the product candidates, the relative risks of successful development of the product candidates, the size of the potential market for the product candidates, competing products and the life-cycle of the product candidates. There have been no significant changes in either the selling price or the method or assumptions used to determine the selling price for a specific unit of accounting during any of the periods presented.

        The Company did not elect the milestone method of revenue recognition under ASC 605-28. Therefore, the additional Phase 1 research and development fees related to the 5th patient dosing were combined with the other consideration received in the arrangement, being the license and Phase 1 research and development reimbursements. Based on the above, the additional fee related to the

13. Research and development collaborative arrangements (Continued)

5th patient dosing was allocated based on the relative selling price percentages determined for the separate units of account at the inception of the Collaborative Arrangements. Upon completion of the 5th patient dosing, the fee allocated to the license was recognized immediately and the fee allocated to research and development reimbursements was recognized on a straight-line basis over the performance period under the cumulative catch-up approach. The 5th patient dosing was completed, and the Company received $5,000 for BRAF and $9,000 for PARP on May 14, 2014 and September 17, 2014, respectively.

        The repurchase consideration of $10,000 associated with the reacquisition of the rights to the PARP inhibitor was charged to research and development expenses as incurred because the rights have no alternative future use. As Merck KGaA, Darmstadt Germany has no further rights in the Ex-PRC territories under the PARP Collaborative Agreements, the advances previously received from Merck KGaA, Darmstadt Germany amounting to $3,018 were offset against the aforementioned repurchase consideration.

        Upon achievement of a 5th patient dosing development based target in the PRC territory under the BRAF Collaborative Arrangements on November 12, 2015, the Company recognized $4,000 of research and development revenue. No other development based targets have been achieved and none of the products have been approved. Hence, no revenue has been recognized related to royalties or commercial event based targets in any of the periods presented. In addition, no payments have been made to the collaborator for any of the periods presented.

        In addition to the collaboration with Merck KGaA, Darmstadt Germany, the Company also provided research and development services to other customers in the PRC amounting to nil, nil and $81, respectively, for the years ended December 31, 2016, 20152019, 2018 and 2014.

        As of December 31, 2016, share-based awards to purchase 77,079,743 ordinary shares were outstanding and share-based awards to purchase 34,712,601 ordinary shares were available for future grant under the Plan.

Modification

        On October 1, 2015 ("Modification Date"), a consultant surrendered 1,000,000 options in exchange for a reduction of the vesting period ("Modified Option Agreement"). The fair value of the options immediately after the modification was higher than that immediately before the modification. The total incremental compensation cost for the modification of $81 was recognized on Modification Date. Subsequently, on November 1, 2015 ("Date of the Change in Employment Status"), the consultant became an employee of the Company. Under the terms of the Modified Option Agreement, the individual retains the same vesting terms; hence, there is no modification to account for. The fair value of the options to the consultant has been re-measured on the Date of the Change in Employment Status and compensation charges have been accounted for prospectively over the remaining vesting period.

        Upon the completion of the Company's IPO on February 8, 2016, a consultant became a member of the Company's board of directors. Under the terms of the original option agreement, the individual retains the option grants on a change in status; hence, there is no modification to account for. The fair value of the options granted by the Company to the consultant has been re-measured as of February 8, 2016 and compensation charges have been accounted for prospectively over the remaining vesting period.

        There were no other modifications to the Company's share option arrangements for the periods presented.

Fair value of options

The Company uses the binomial option-pricing model was applied in determining the estimated fair value of the options granted. The model requires the input of highly subjective assumptions including the estimated expected stock price volatility and, the exercise multiple for which employees are likely to exercise share options. For expected volatilities, the trading history and observation period of the Company'sCompany’s own share price movement has not been long enough to match the life of the share option. Therefore, the Company has made reference to the historical price volatilities of ordinary shares of several comparable companies in the same industry as the Company. For the exercise multiple, the Company was not able to develop an exercise pattern as reference, thus the exercise multiple is based on management'smanagement’s estimation, which the Company believes is representative of the future exercise pattern of the options. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury Bills yield curve in effect at the time of grant. Prior to the completion
