Item 1. Business

Overview

We are a globallycommercial-stage biotechnology company focused clinical-stage biopharmaceutical company dedicated to becoming a leader in the discoveryon developing and development ofcommercializing innovative molecularly targetedmolecularly-targeted and immuno-oncology drugs for the treatment of cancer. Our internally-developed lead drug candidates are currently in late-stage clinical trials, including 21 registration or registration-enabling trials in 14 discrete cancer indications. We believehave submitted three new drug applications for regulatory approval in China and are planning for new drug launches and additional submissions in China and the next generation ofUnited States in 2019 and 2020. In addition, we are marketing three in-licensed cancer treatment will utilize therapeutics bothdrugs in China from which we have been generating product revenue since September 2017.
We started as monotherapiesa research and development company 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,Beijing in 2010, focusing on developing best-in-class oncology drugs. Over the last nine years, we have developed into a proprietary cancer biology platformfully-integrated global biotechnology company with operations in China, the United States, Europe and Australia, including a more than 800-person global clinical development team running over 50 ongoing or planned clinical trials as of January 24, 2019. We also have a growing commercial team that addresses the importanceis selling our existing in-licensed drugs in China and preparing for launches of tumor-immune system interactionsour internally-developed drug candidates in China and the valueUnited States, as well as internal manufacturing capabilities in China that are operational or under construction for the clinical and commercial supply of primary biopsies in developing new models to support our small molecule and biologic drug discovery effort.

candidates.

Our strategy is to develop a pipeline oflead internally-developed drug candidates withinclude the potential to befollowing:
Zanubrutinib (BGB-3111) - a potentially best-in-class monotherapies and also important componentsinvestigational small molecule inhibitor of multiple-agent combination regimens. Over the last six years, using our cancer biology platform, we have developed clinical-stage drug candidates that inhibit the important oncology targets Bruton'sBruton’s tyrosine kinase, or BTK, RAF dimer protein complexdesigned to maximize BTK occupancy and PARP family of proteins, and an immuno-oncology agentminimize off-target effects, 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 being evaluated in a broad pivotal studiesclinical program in North America, Europe, Australia, New Zealand, and China. Our PD-1, PARP and RAF dimer inhibitors are currently in the dose-expansion phases of their respective clinical trials. As of March 20, 2017, trials of our four clinical-stage drug candidates, as monotherapiesChina and in combination, have enrolledother markets, including the United States, Europe and Australia, which we refer to as globally, for which we submitted for approval in China in 2018 initially for the treatment of patients with relapsed or refractory (R/R) mantle cell lymphoma, or MCL, and chronic lymphocytic leukemia or small lymphocytic lymphoma, or CLL/SLL. We subsequently received priority review in China for both R/R MCL and R/R CLL/SLL. We also plan to submit in 2019 or early 2020 a total of over 980 patients. We have Investigational New Drug,new drug application, or IND, Applications in effect for our BTK, PD-1 and PARP inhibitors withNDA, to the U.S. Food and Drug Administration, or FDA. All four of our drug candidates are in the clinicFDA, and an NDA in China including our BTK drug candidatefor Waldenström’s Macroglobulinemia, or WM. In the United States, the FDA has granted zanubrutinib Fast Track status in WM and Breakthrough Therapy designation for the treatment of adult patients with MCL who have received at least one prior therapy. We plan to launch zanubrutinib in China and the United States if we receive approval from the relevant regulatory authorities;
Tislelizumab (BGB-A317) - an investigational humanized IgG4 monoclonal antibody against the immune checkpoint receptor programmed cell death protein 1, or PD-1, specifically designed to minimize binding to FcγR on macrophages, that is currently being evaluated in a broad pivotal clinical program for both solid tumor and hematological indications, both globally and in China, for which we submitted for approval in China in 2018 initially for the treatment of R/R classical Hodgkin’s lymphoma, or cHL. We subsequently received priority review in China, and we plan to launch tislelizumab in China if we receive approval. We also plan to file an NDA in China for the treatment of urothelial bladder cancer, or UBC; and
Pamiparib (BGB-290) - an investigational small molecule inhibitor of poly ADP-ribose polymerase 1, or PARP1, and PARP2 enzymes that is being evaluated in two pivotal studies. clinical trials in China, a global Phase 3 trial, and earlier-stage trials in solid tumor cancers.
In addition to our three late-stage clinical drug candidates, our pipeline also includes three internally-developed drug candidates in early stage clinical development: lifirafenib (BGB-283), an investigational RAF dimer inhibitor; BGB-A333, an investigational humanized monoclonal antibody against the immune checkpoint receptor ligand PD-L1; and BGB-A425, an investigational humanized monoclonal antibody against TIM-3. We also pursue in-licensing opportunities that, among other things, allow us to help our collaborators by leveraging our capabilities in clinical development and commercialization in China and other Asia-Pacific countries. Our business development efforts have led to a development-stage portfolio that includes sitravatinib, an investigational, spectrum-selective kinase inhibitor in clinical development by Mirati Therapeutics, Inc., or Mirati, for which we have in-licensed development and commercial rights in Asia (excluding Japan), Australia and New Zealand; and ZW25 and ZW49, two bispecific antibody-based biologic drug candidates targeting HER2, in clinical

development by Zymeworks Inc., or Zymeworks, for which we have in-licensed development and commercial rights in Asia (excluding Japan), Australia and New Zealand.
We entered into a strategic collaboration with Celgene Corporation in August 2017, in which we obtained an exclusive license to market in China Celgene’s approved cancer therapies ABRAXANE®, REVLIMID® and VIDAZA®, as well as rights in China to develop and commercialize avadomide (CC-122), an investigational next-generation Cereblon modulator currently in clinical development by Celgene outside of China for lymphoma and hepatocellular carcinomas, or HCC. As part of the collaboration, we also granted Celgene an exclusive right to develop and commercialize tislelizumab for solid tumors in the United States, Europe, Japan and the rest of the world other than Asia.
We believe that each of our clinical-stage drug candidateswe are well-positioned to capture significant market opportunities in China for innovative cancer therapies, including those created by recent regulatory reforms and new reimbursement policies. China is the firstsecond largest pharmaceutical market in their respective classes being developedthe world based on revenue. We believe that there is a large and growing opportunity for novel cancer therapeutics in China underbased on significant unmet medical need, a large target patient population, expanding reimbursement coverage, and increasing treatment affordability and willingness to pay. In addition, China’s chief drug regulator, the Category 1.1 domesticNational Medical Products Administration, or NMPA, has undertaken significant regulatory pathwayreforms that are designed to enter into human testingaccelerate the development of new innovative drugs and allow China to present clinical data.

        Our research operations arebe an integral part of global drug development. In addition, innovative oncology drugs have been included in the most recent National Reimbursement Drug List, or NRDL, reducing out-of-pocket expenses for patients. We believe that access to the large number of patients in China whichduring clinical development as well as commercialization creates new opportunities for us. Leveraging our strong China presence and experience, as well as our commitment to global standards of innovation and quality, we believe confers several advantages including accessthat we have a unique ability 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 teameffectively take advantage of 348 individuals in China, the United States, and Australia with deep scientific talent and extensive global pharmaceutical experience who are deeply committed to advancing ourthese opportunities.

Our Strategy
Our mission is to become a global leader in next-generation cancerthe discovery, development and commercialization of innovative therapies.

        We believe that oncology treatment has entered an era of revolutionary change in which cancer drugs will be used both as monotherapy and in combination In the near term, we plan to attack multiple underlying mechanisms 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 basedfocus 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 tumors with particular mutations. In addition, the development of immuno-oncology agents such as antibodies targeting the CTLA-4 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. 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 thatpursuing what we believe haveare the following significant potential alone or in combination for treatingopportunities:

Globally Develop and Commercialize Zanubrutinib, 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 resistance is a major problem and that better outcomes will be achievable by combining multiple drugs as it is done in treating infectious diseases.

        The next generation of cancer therapies will be based, we believe, on advances in four areas:

    Reclassification of disease based on underlying molecular defect.Potentially Best-in-Class BTK Inhibitor. 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 thusZanubrutinib 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, as locally developed compounds, to qualify for a separate, and potentially accelerated, regulatory path.

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

BGB-3111, Bruton's Tyrosine Kinase Inhibitor

BGB-3111 is a potent and highly selectiveinvestigational small molecule inhibitor of BTK inhibitor. We arethat is currently developing BGB-3111being evaluated both as a monotherapy and in combination with other therapies to treat various lymphomas. Our clinical experience to date suggests a potentially best-in-class profile. To pursue this opportunity, we are conducting a broad pivotal clinical program globally and in China. We have submitted for approval in China for two indications based on single-arm Phase 2 clinical trials in patients with R/R CLL/SLL and R/R MCL. Both applications have been accepted and are being reviewed under priority review status. In addition, we are conducting three global Phase 3 trials: head-to-head against ibrutinib, an approved BTK inhibitor, for patients with WM; against bendamustine plus rituximab for patients with treatment naïve, or TN, CLL/SLL; and head-to-head against ibrutinib for patients with R/R CLL/SLL. Further, we are conducting a global pivotal Phase 2 trial in combination with obinutuzumab in follicular lymphoma, or FL, a pivotal Phase 2 trial in China in WM, and we have recently begun a global study in R/R marginal zone lymphoma, or MZL. Subject to the successful completion and satisfactory results of these trials, we expect to submit for approval of zanubrutinib in the United States in 2019 or early 2020, where it has been granted Fast Track status for patients with WM and Breakthrough Therapy designation for patients with R/R MCL. We also plan to file an NDA in China for patients with WM.

Develop and Commercialize Our Investigational Checkpoint Inhibitor, Tislelizumab, in a Rapidly and Favorably Evolving China Market and Other Markets. We believe that there is a large and growing opportunity for novel cancer therapeutics in China and that the market opportunity for PD-1/PD-L1 antibody therapies may be especially attractive, as 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). We believe that we are uniquely positioned to capture this opportunity with our strong presence and experience in China and our integrated global clinical development capabilities in China and other Asia-Pacific countries, the United States, Europe and Australia. We have submitted an NDA in China to market tislelizumab for the treatment of patients with R/R cHL, and the application has been accepted and is being reviewed under priority review status. We are currently running 11 registration or potentially registration-enabling trials in six tumor types and expect to commence additional global pivotal trials in 2019 and 2020. We also plan to submit an NDA in China for patients with UBC. We have additional earlier stage exploratory studies ongoing, and we plan to initiate other studies.
Establish a varietyLeadership Position by Further Expanding Our Capabilities. Although we believe that we have significant integrated capabilities in research and clinical development, manufacturing and commercialization, we plan

to continue to strengthen and expand our operations. In particular, we plan to significantly expand our commercial capabilities in China in preparation for the potential launch of our drug candidates and to support our existing marketed drugs. We have an established commercial team in China, which provides coverage of large hospitals and physician clients. As a result of the improving reimbursement environment in China, which is expected to provide access to innovative medicines for a significantly larger number of patients, we believe that the scale of our commercial organization and the breadth of our market coverage will become even more important. We plan to invest in expanding our teams of sales and marketing, market access, medical affairs, compliance, manufacturing, and other supporting functions. We aim to become a leading organization in the commercialization of oncology drugs in China. Outside of China, we are currently building commercial capabilities in the hematology-oncology area in the United States. In addition, we plan to continue to invest in building our global clinical development capabilities, which we believe will provide a competitive advantage in allowing us to conduct pivotal trials to support approvals globally and in China.
Take Advantage of Significant Regulatory Reforms in China to Accelerate Global Drug Development. Historically, the regulatory environment in China has been considered highly challenging, with clinical development significantly delayed and regulatory approvals taking much longer than in the United States and Europe. To address these challenges, the NMPA has issued a series of reform policies and opinions, which, among many things, are expected to expand access to clinical patients and expedite development and approval by removing delays and creating an environment with international quality standards for drug development, manufacturing and commercialization in China. We expect that these regulatory reforms will allow clinical trials in China to play a major role in global drug development programs. We also believe that the ability to effectively operate in China and integrate trials conducted in China with those in the rest of the world will be of increasing strategic importance. We are already taking advantage of these opportunities by conducting and leading dual-purpose global / China registration trials.
Expand Our Product Portfolio and Pipeline Through Collaborations with Other Biopharmaceutical Companies to Complement Our Internal Research. We expect to further expand our portfolio of drugs and drug candidates, in oncology as well as potentially in other therapeutic areas, through internal research and external collaborations, such as our collaborations with Celgene, Mirati and Zymeworks. We intend to pursue collaborations with other biopharmaceutical companies both in China and globally by leveraging our strong clinical development capabilities globally and our commercial capabilities in China. We have pursued and plan to continue to pursue business development opportunities in which development in China is expected to contribute to, and potentially accelerate, the global development program. We believe that there will be increasing interest by international biopharmaceutical companies in seeking collaborations in Asia, particularly in oncology, because clinical recruitment is a major bottleneck in new drug development.

Zanubrutinib (BGB-3111), a BTK Inhibitor
Zanubrutinib is an investigational small molecule inhibitor of BTK that is currently being evaluated in a broad pivotal clinical program globally and in China as a monotherapy and in combination with other therapies to 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%.

        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 randomized Phase 3 trial in Waldenström's Macroglobulinemia, or WM that will enroll approximately 170 patients at clinical sites in North America, Europe, Australia, 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 levels 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 is a potent BTK inhibitor with anti-tumor activity observed 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 Australia and the United States with obinutuzumab, an anti-CD20 monoclonal antibody approved for CLL.


Mechanism of Action

BTK is a key component of the B-cell receptor, or 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

and Competition

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,non-Hodgkin’s lymphoma, or NHL, and acute B-cell leukemias.Hodgkin’s lymphoma, or HL. Depending on the origin of the cancer cells, lymphomas arecan also be characterized as B-cell or T-cell lymphomas. B-cell lymphomas make up approximately 85% of non-Hodgkin's lymphomasNHLs and comprise a variety of specific diseases involving B-cells at differing stages of maturation or differentiation. Preliminary dataAccording to statistics from animal models involving BGB-3111the Surveillance, Epidemiology and third-party BTK inhibitors also suggest potential applicationsEnd Results, or SEER, program of the U.S. National Cancer Institute, there were 72,240 new NHL cases and 20,140 deaths, and 20,110 new CLL cases and 4,660 deaths in solid tumors2017 in the United States. Similar SEER analyses calculate U.S. incidence rates for MCL of 3,000 and inflammatory diseases,1,350 for WM. According to a published study (Chen et al., Cancer Statistics in China, 2015, CA Cancer J. Clin. 2016; 66(2):115-32), which could substantially expand our market opportunity.

Current Therapieswe refer to as Chen et al. 2016, and Limitations

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 treatment oftreating 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 BCR signalingBTK inhibitors, primarily with the BTK inhibitor ibrutinibPI3K inhibitors, idelalisib, copanlisib and duvelisib, and the PI3K deltaBcl-2 inhibitor, idelalisib. In addition, there arevenetoclax. Most recently, a cell-based therapy, YESCARTA® (axicabtagene ciloleucel) was approved for the treatment of adult patients with diffuse large B-cell lymphoma, or DLBCL, who have failed at least two other inhibitorskinds of BCR signaling pathways in development, such as PI3K delta/gamma, IRAK4 and SYK.

treatment. YESCARTA® is a genetically modified autologous T-cell immuno-oncology therapy directed at CD19.

The BTK inhibitor ibrutinibIMBRUVICA® (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,that time, ibrutinib has received supplemental FDA approvals for the treatment of patients with CLL, CLL patients with 17p deletion, patients with WM, andpatients with MZL patients who have received at least one prior anti-CD20-based therapy.therapy, patients with chronic graft versus host disease after failure of one or more lines of systemic therapy, for use in combination with obinutuzumab in CLL, and in combination with rituximab in WM. Ibrutinib is also approved by the EMAEuropean Medicines Agency for the treatment of patients with MCL, CLL orand WM. Ibrutinib has subsequently been approved in over 4090 countries but not China. Reportedand regions, and it was approved and launched in China at the end of 2017. In 2018, global sales of ibrutinibrevenues for BTK inhibitors were approximately $2US$4.5 billion according to published reports. Another BTK inhibitor, CALQUENCE® (acalabrutinib) was approved by the FDA in 2016.

        Despite2017 under accelerated approval for the clinical and commercial successtreatment of ibrutinib, we believe based on its product profile that meaningful differentiation is possible inpatients with MCL who have received at least one prior therapy. In late 2017, ibrutinib was the following aspects:

    Safetyfirst BTK inhibitor approved 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 chroniclaunched in China, for the 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 ofwith R/R CLL/SLL and R/R MCL. Subsequently, in July 2018, 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.

    Combinability with ADCC-dependent antibodies.  Anti-CD20 agents, such as rituximab, obinutuzumab and ofatumumab, are considered effective therapiesalso approved 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.first-line CLL.

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 25, 2019, we had enrolled more than 1,300 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 European countries 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,such as WM, CLL/SLL, FL, MCL, MZL, WM, 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. In addition, sustained full BTK occupancy was observed in the lymph nodenodes especially for the 160 mg BIDtwice daily dosing regimen.

On October 3, 2016, the most recent data analysis. Based on the pharmacokinetics, pharmacodynamics, safety and efficacy evaluation of BGB-3111 in the dose-escalation phase, 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 median time to response (>PR, or partial response) was 85 days (55-749). At the earlier parttime of the treatment course.data cutoff, 62 patients remained on study treatment. The most frequent AEs (³20%) of any attribution were upper respiratory tract infection (39%)overall response rate, or ORR, was 92% (67/73), petechiae (spots that appear on the skin as a result of bleeding) / purpura (subcutaneous bleeding) / contusion (33%), nausea (24%), diarrhea (24%)major response rate, or MRR, was 82%, and constipation (21%), all grade 1 or 2 in severity except for one case41% of diarrhea (3%). Four serious adverse events, or SAEs, were assessed as possibly related to BGB-3111, including one case each of grade 3 cryptococcal meningitis, grade 3 pneumonia, grade 2 atrial fibrillation, or AF, and grade 2 vomiting. Other grade 3 or greater events considered possibly related to BGB-3111 included two cases 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, hemorrhage 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,defined as a >90% reduction in baseline IgM levels and improvement of extramedullary disease by CT scan. The 12-month progression-free survival, or PFS, was estimated

at 89%. The median PFS had not yet been reached. The median IgM decreased from 32.7 g/L (5.3-91.9) at baseline to 8.2 g/L (0.3-57.8). The median hemoglobin increased from 8.85 g/dL (6.3-9.8) to 13.4 g/dL (7.7-17.0) among 32 patients with hemoglobin <10 g/dL at baseline.

Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma

On October 24, 2018, we announced the acceptance by the NMPA of our NDA for zanubrutinib for the treatment of patients with R/R CLL/SLL, together with the top line clinical data that supported the filing. The trial was a 91-patient single-arm pivotal Phase 2 study in Chinese patients with R/R CLL/SLL treated with zanubrutinib, dosed at 160 mg orally twice daily, or BID. An independent review of response data from this study, with a data cut-off of June 15, 2018 and a median follow-up of 9.1 months, showed an ORR of 80%, inclusive of complete response, or CR, of 2%, PR of 39%, and partial response with lymphocytosis, or PR-L, of 40%. The median duration of response had not been reached, as a majority of the responders remained in a response. The safety profile results were consistent with previously reported clinical data for zanubrutinib, which are described below. We plan to submit updated data with additional follow-up of the patients in this trial in support of the NDA.
On June 14, 2017, at the 14th International Conference on Malignant Lymphoma in Lugano, Switzerland, data were presented from patients with CLL/SLL from the same Phase 1 trial that included WM patients described above. As of the data cutoff of March 31, 2017, 69 patients with CLL or SLL (18 TN, 51 R/R) were enrolled in the trial.
At the time of the data cutoff, 66 patients (16 TN and 50 R/R) had more than 12 weeks of follow-up and were evaluable for efficacy, and three other patients had less than 12 weeks of follow-up. After a median follow-up of 9.610.5 months (3.0–24.7(2.2-26.8 months), 32the ORR was 94% (62/66) with CRs in 3% (2/66), PRs in 82% (54/66), and PR-Ls in 9% (6/66) 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,patients. Stable disease, or MR, or better,SD, 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 out5% (3/66) 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 evaluable patientspatients. A patient with theMYD88L265P /CXCR4WT genotype, eight achieved VGPRs, seven achieved PRs, two achieved MRs, and 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 response 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%.

        In addition to data in WM, updated data on BGB-3111 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 orpleural effusion discontinued treatment prior to week 12 byand was not evaluable for response. There was one instance of Hodgkin’s transformation.

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,purpura (subcutaneous hemorrhage), which was the only AF case reported. The case of purpura was the only major bleeding event;event. Additional AEs of interest included one case of each grade 2 diarrhea and grade 2 atrial fibrillation. A total of 18 SAEs occurred in 13 patients, with no other casesSAE occurring in more than one patient. Only one patient discontinued treatment due to an AE, a grade 2 pleural effusion.

Mantle Cell Lymphoma
On December 1, 2018, at the 60th American Society of serious hemorrhage (definedHematology, or ASH, Annual Meeting, in San Diego, CA, two data sets were presented on zanubrutinib in MCL patients from our Phase 2 and Phase 1 studies.
The Phase 2 study was a single arm, open-label, multi-center, pivotal trial of zanubrutinib as³ a monotherapy in Chinese patients with R/R MCL that enrolled 86 patients who had received a median of two prior lines of therapy (range of 1-4). Patients were treated with zanubrutinib, dosed at 160 mg orally BID. The primary endpoint of the trial was ORR assessed by independent review committee, or IRC, using PET-based imaging according to the Lugano Classification 2014.
As of March 27, 2018, 85 patients with R/R MCL were evaluable for efficacy and 65 patients (75.6%) remained on study treatment. The median follow-up time for patients enrolled in the trial was 35.9 weeks (1.1-55.9). The IRC-assessed ORR was 83.5% (71/85); the CR rate was 58.8% (50/85); and the PR rate was 24.7% (21/85). The 24-week PFS was estimated at 82%. The median PFS had not yet been reached. With 24.1 weeks median follow-up (0.1-41.1), the median duration of response, or DOR, had not yet been reached and 90% of responders were still in response at 24 weeks.

Among events 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. SDspecial interest for BTK inhibitors, diarrhea was observed in 2% (1 outnine patients (10.5%), all grade 1-2. Major hemorrhage was observed in one patient (1.2%) with a blastoid variant of 46 patients)MCL who had intra-parenchymal CNS bleeding. No cases of atrial fibrillation/flutter were reported in this trial.

The Phase 1 study is an open-label trial of zanubrutinib as a monotherapy in patients with different subtypes of B-cell malignancies, including MCL, and is being conducted in Australia, New Zealand, the United States, Italy, and South Korea. As of July 24, 2018, 48 patients with TN (n=9) or R/R (n=39) MCL had been enrolled in the trial and the median follow-up time was 12.7 months (0.7-38.0). Forty-five patients including six with TN and 39 with R/R MCL, were evaluable for efficacy in this analysis, per the Lugano 2014 classification. At the time of the data cutoff, 26 patients remained on study treatment.
The investigator-assessed ORR was 88.9% (40/45); the CR rate was 26.7% (12/45); and the PR rate was 62.2% (28/45). The majority of patients were assessed via CT-scan; PET scans were optional per trial protocol. The median DOR was 16.2 months and the median PFS for R/R patients was 18.0 months (0.7-30.7).
Zanubrutinib tolerability was generally consistent with previous reports in patients with various B-cell malignancies and the majority of AEs were grade 1 or 2 in severity. The most frequent AEs of any attribution were petechia/purpura/contusion (33.3%), diarrhea (33.3%), upper respiratory tract infection (29.2%), fatigue (25.0%), and constipation (18.8%). Grade 3-5 AEs occurred in 56.3% of patients. The patient who discontinued prior to week 12Grade 3-5 AEs of any attribution reported in > three patients included anemia (8.3%), major hemorrhage (6.3%), cellulitis (6.3%), myalgia (6.3%), neutropenia (6.3%), pneumonia (6.3%); and thrombocytopenia (6.3%). Discontinuation due to pleural effusion was not evaluableAEs occurred in 18.8% of patients with all but one event (peripheral edema) determined to be unrelated to study drug. There were four deaths due to AEs, which were all determined by the investigators to be unrelated to zanubrutinib treatment.

Other Lymphomas
We have a broad clinical program investigating zanubrutinib for response. No instancesthe treatment of disease progression or Richter's transformation had occurred.

Pooled Analysis of Safety Data from Monotherapy Trials
At the 23rd Congress of the European Hematology Association, or EHA 2018, the pooled safety data were presented from patients with various B-cell lymphomas in four ongoing zanubrutinib monotherapy studies, totaling 476 patients with a median exposure of seven months. Overall, the data suggested that exposure levels of zanubrutinib resulting in complete and Byrd et al.sustained BTK inhibition can be achieved and that zanubrutinib was generally well-tolerated. There were infrequent AEs of interest with BTK inhibitor therapy, such as atrial fibrillation/flutter (2%), NEJM 2013

        In January 2017major hemorrhage (2%), and grade 3 and above diarrhea (1%). Treatment discontinuation due to zanubrutinib-related AEs was uncommon (3%). The majority of patients (94%) experienced one or more AEs of any attribution, primarily grades 1 or 2. The most common grade 3 or higher AEs of any attribution were neutropenia/neutrophil count decreased/febrile neutropenia (14%), anemia (7%) and thrombocytopenia/platelet count decreased (7%). SAEs were reported in 116 patients (24%), with 38 patients (8%) assessed by the investigator as related to zanubrutinib. The most common SAEs were pneumonia/lung infection (6%), pleural effusion (1%), and febrile neutropenia (1%). The only treatment-related SAE reported in greater than 1% of patients was pneumonia/lung infection (2%). No cases of pneumocystis jiroveci pneumonia, or PJP, or cytomegalovirus, or CMV, reactivation were reported. The most common bleeding events observed included petechiae/purpura/contusion (26%) and hematuria (11%). Major hemorrhage (2%) included gastrointestinal hemorrhage/melena (n=3), intraparenchymal CNS hemorrhage grade 5, hematuria, purpura, hemorrhagic cystitis, renal hematoma, and hemothorax (one each). The median time to first major hemorrhage was 1.2 months. Among patients with emergent atrial fibrillation/flutter (n=8), a majority had known risk factors including hypertension (n=2), pre-existing cardiovascular disease (n=2), and concurrent infection (n=1). The cumulative rates of grade 3 or higher infections were 14% at six months, 19% at 12 months and 21% at 18 months. The exposure-adjusted incidence rate was 1.82 per 100 person-months. The most common second primary malignancies included basal cell carcinoma (3%) and squamous cell carcinoma of the skin (1%).

Clinical Development Plan
Based on the clinical data to date, we initiatedbelieve that zanubrutinib has a potentially best-in-class profile, and we are running a broad global multi-center randomizedpivotal program in multiple indications including seven registration or registration-enabling clinical trials.
Globally, we have an ongoing monotherapy head-to-head Phase 3 trial versus ibrutinib in WM, which has closed to new patient screening and completed enrollment having met the enrollment target. We are also conducting an ongoing Phase 3 trial compared to bendamustine and rituximab in patients with TN CLL/SLL and a head-to-head Phase 3 trial in R/R CLL/SLL versus ibrutinib. Additionally, we have an ongoing pivotal Phase 2 trial in combination with GAZYVA® (obinutuzumab) in patients with R/R FL, which is designed as a pivotal trial for accelerated or conditional approval and will require a confirmatory study, as well as a Phase 2 trial in patients with R/R MZL.
Zanubrutinib was granted, by the FDA, Fast Track designation for the treatment of patients with WM in whichJuly 2018, and was granted Breakthrough Therapy designation in January 2019 for the treatment of adult patients with MCL who have

received at least one prior therapy. We plan to submit in 2019 or early 2020 an NDA to pursue an approval of zanubrutinib in the United States.
In China, we are conducting three separate pivotal Phase 2 trials of zanubrutinib as monotherapy in patients with R/R MCL, R/R CLL/SLL, and WM. We have announced the acceptance of our filings for approval in MCL and CLL/SLL on August 26, 2018 and October 24, 2018, respectively.
If we receive conditional approval instead of full approval, we will be required to conduct one or more confirmatory studies after such conditional approvals. If approved, 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 whocommercialize zanubrutinib shortly after approval. In addition, we 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 inconducting 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 pivotal2 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 additionChina 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 obinutuzumabzanubrutinib 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

        In China, we have initiated two pivotal studies for BGB-3111. In March 2017, we initiated single-arm, open-label, multi-center pivotal clinical trials of BGB-3111 monotherapy in China in


patients with relapsed or refractory MCL and in patients relapsed and refractory CLL or SLL, respectively. The primary endpoint in each of these trials 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.

        We plan to expand our registration program for BGB-3111. In addition, we plan to present data from the combination studies of BGB-3111 with obinutuzumab and BGB-3111 with BGB-A317 at medical conferences in 2017.

BGB-A317, PD-1 Antibody

BGB-A317Tislelizumab is an investigational 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 in combination with standard of care to treat various solid and hematological cancers. We have a global strategic collaboration with Celgene for tislelizumab for solid tumors outside of Asia (other than Japan) as a combination agent for various solid-organ and blood-borne cancers. PD-1 is a cell surface receptor that plays an important rolefurther described 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, or 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 abilityantibodies by an engineered Fc region designed to bind Fcminimize binding to FcγR on macrophages, thereby abrogating antibody-dependent phagocytosis, a potential mechanism of T-cell clearance, which we believe may minimize potentially negative interactions with other immune cells based on preclinical data.

There are approximately six more PD-1 and PD-L1 agents in late stage development in China, of Fcgwhich one has filed for approval as of February 20, 2019.RI may compromise
Globally, the efficacytop four PD-1/PD-L1 antibody drugs had sales of anti-PD-1 antibodies by attracting immune suppressive cells and depleting the T-cell population necessary for attacking the tumor cells. With limited to no ability to bind to the receptor, we believe BGB-A317 could potentially have improved activities. In addition, BGB-A317 has a unique binding signature to PD-1 with high affinity and superior target specificity. In preclinical studies, BGB-A317 showed better cellular functional activitiesapproximately $15 billion 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.

2018 based on public reports. We believe that there could beis a large commercial opportunity in China for PD1 antibodies as currentlyPD-1 and PD-L1 antibody drugs. Currently available clinical data suggest that some of the most prevalent cancers in China, such as lung gastric,cancer, GC, liver cancer and esophageal cancersEC, are responsive to this class of agents. We believe we are well positionedAccording to take advantagethe World Health Organization's Globocan online database, China suffered 37%, 44%, 47%, and 54% of this opportunity.all deaths from lung cancer, GC, liver cancer and EC, 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 potentialUnited States and the European Union, or EU. According to combine BGB-A317 with our multiple clinical-stageChen 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. In comparison, the estimated annual incidence of the top ten PD-1 responsive tumors is 0.9 million out of 1.7 million in total annual cancer


incidence in the United States, 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-3111,0.9 million out of the 1.8 million total in the EU5 countries (United Kingdom, France, Germany, Spain and BGB-283.

As of March 20, 2017,December 8, 2018, we have dosedenrolled over 4002,200 patients in clinical trials of tislelizumab, including combination trials. Preliminary data from our monotherapy Phase 1 trials suggested that tislelizumab was generally well-tolerated and exhibited anti-tumor activity in a variety of tumor types. There is no guarantee that these results will be reproduced in pivotal trials.
Hodgkin’s Lymphoma
On December 3, 2018, data from a pivotal Phase 2 clinical trial of tislelizumab in R/R cHL were presented at the ASH meeting. This single arm, open-label, multi-center, pivotal Phase 2 trial of tislelizumab as a monotherapy in Chinese patients with BGB-A317R/R cHL enrolled 70 patients who failed to achieve a response or progressed after autologous stem cell transplant, or ASCT, or received at least two prior lines of systemic therapy for cHL and were not an ASCT candidate. Patients were treated with tislelizumab, dosed at 200 mg intravenously every three weeks. The primary endpoint of the trial is ORR-assessed by IRC using PET-based imaging according to the Lugano Classification 2014.
As of May 25, 2018, 70 patients with R/R cHL were evaluable for efficacy and 53 patients (75.7%) remained on study treatment. Thirteen patients received prior ASCT, and the remaining 57 patients were ineligible for prior ASCT, including 53 for failure to achieve an objective response to salvage chemotherapy, two for inadequate stem cell collection or unable to collect stem cells, and two for co-morbidities. The patients had a median of three prior lines of systemic therapy with a range of two to eleven. The median study follow-up was 7.85 months (3.4-12.7).
The ORR assessed by IRC was 85.7% (60/70); the CR rate was 61.4% (43/70); and the PR rate was 24.4% (17/70). Among patients who had received prior ASCT, 92.3% (12/13) achieved an objective response, with nine patients (69.2%) achieving a CR. The DOR had not yet been reached. The estimated event-free rates at nine months were 84%. PFS data were preliminary and six-month PFS was estimated at 80%. The median PFS had not yet been reached.
The majority of AEs were grade 1 or 2 in either monotherapyseverity. The most frequently reported TEAEs of any grade were pyrexia (52.9%), hypothyroidism (30.0%), weight increased (28.6%), upper respiratory tract infection (27.1%), cough (17.1%), white blood cell count decreased (14.3%), and pruritus (14.3%). Grade ≥3 TEAEs occurred in 21.4% of patients. The most frequently reported grade 3 or combination trials. higher TEAEs were upper respiratory tract infection (2.9%) and pneumonitis (2.9%). Four patients (5.7%) discontinued study drug due to TEAEs, including pneumonitis (n=2), focal segmental glomerulosclerosis (n=1), and organizing pneumonia (n=1); there were no cases of TEAE leading to death. Immune-related AEs reported in more than five percent of patients included thyroid disorder (18.6%), pneumonitis (5.7%), and skin adverse reactions (5.7%).

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 TEAE are indicated in the table 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%).

All grades, regardless of causality; Data cut-off April 27, 2018; 6 months after Last Patient Enrolled; Source: BGB-A317 IB v6.0. 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%).

Immune-Related Treatment-Emergent Adverse Events and Deaths
Immune-related TEAEs, or irTEAEs, of any grade were reported in approximately 25% of patients but were primarily low grade (3% to 5% ≥ grade 3). These irTEAEs, however, have well-established algorithms for treatment and are considered manageable.
Across the monotherapy studies, the rate of treatment emergent SAEs, or TESAEs, ranged from 16% to 37% in patients with a variety of different disease characteristics. TESAEs considered to be related to treatment with tislelizumab were notably lower, ranging from 6% to 13%.
There have been some deaths reported across the active studies with clinical data available (as of the cut-off dates ranging from April 25, 2018 to August 29, 2018), of which less than 0.5% of the total patient population were deemed to be related to treatment with tislelizumab.
Clinical Development Plan
We are running a broad development program for tislelizumab, including 11 registration or registration-enabling clinical trials. These include global pivotal trials in Asia-prevalent cancers, such as non-small cell lung cancer, or NSCLC, EC, GC and HCC, which are intended to support regulatory submissions globally and in May 2016, weChina. We have initiated the dose-expansion phase ofpivotal or Phase 3 trials to evaluate tislelizumab as a potential second- or third-line treatment compared to docetaxel in patients with NSCLC; as a potential first-line treatment compared to sorafenib in patients with HCC and in second or third line HCC used as a monotherapy; as a potential first-line treatment in GC in combination with platinum and fluoropyrimidine-based chemotherapy; and as a potential second-line treatment compared to investigator-chosen chemotherapy in patients with esophageal squamous cell carcinoma, or ESCC, and as a potential first-line treatment in advanced ESCC patients in combination with platinum and fluoropyrimidine-based chemotherapy. Under our collaboration with Celgene, Celgene has opened enrollment in its first Phase 1 clinical3 trial in Stage 3 NSCLC examining tislelizumab in combination with chemoradiation. We have also recently initiated a global Phase 2 trial in patients with relapsed or refractory solid tumor patientsmature T- and NK-cell lymphomas.
We have four China pivotal trials ongoing, including two Phase 2 trials in Australia, New Zealand, the United States, Korea, and Taiwan.

        On November 11, 2016, we presented updated data from the dose escalation phase of our ongoing Phase 1 trial for a total of 103 patients with advanced solid tumors at the Society for Immunotherapy of Cancer, or SITC, 31st Annual meeting. The preliminary clinical data showed that BGB-A317 was well-tolerated with AEsR/R cHL and in keeping with the class effect. Among 103 patients evaluable for safety at the time of the data cutoff for the current safety analysis on August 15, 2016, the most common treatment-related AEs (³ 5%) were fatigue (19%), diarrhea (13%), rash (11%), pruritus (11%), nausea (8%), hypothyroidism (7%), and infusion related reaction (6%). Treatment-related SAEs included four cases of colitis, two cases of hypotension, and one case each of diarrhea, diabetes mellitus, diabetic ketoacidosis, dyspnea, hypoxia, infusion-related reaction, and pneumonitis. Among these, grade 3 treatment-related SAEs included the two cases of hypotension and one case each of colitis, diabetes mellitus, diabetic ketoacidosis, dyspnea, hypoxia, and pneumonitis. Other treatment-related grade 3 AEs included two cases each of fatigue and hyperglycemia, and one case each of back pain, elevated alanine aminotransferase and elevated gamma-glutamyl transferase. The table below summarizes the AE events.



BGB-A317 Phase 1 Trial: Most Common Treatment-Related Adverse Events

        A mixed patient population of 27 different tumor types was included in this data analyses, in which patients with melanoma, NSCLC or HNSCC were not enrolled, and patients with renal cell cancer and urothelial carcinoma together represented close to 15% of the enrolled patients. Among 99 patients evaluable for efficacy as of September 30, 2016, anti-tumor activities were observed in 15 patients with a PR and 23 patients with SD. The PRs include three PRs in nine renal cell carcinoma patients; three in sixPD-L1 positive second/third-line urothelial cancer, patients;or UC, and 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

        Four patients who discontinued treatment before the first tumor imaging assessment due to symptomatic deterioration (three cases) or grade 2 infusion reaction (one case) were not evaluable for efficacy. One of seven patients with mesothelioma discontinued therapy due to treatment-related grade 3 pneumonitis prior to obtaining confirmation of an initial PR. Additionally, two of 23 patients with ovarian cancer and one of five patients with cervical cancer had significant tumor shrinkage qualifying for a PR in one imaging assessment but not confirmed 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, we have two internal combination clinical trials ongoing. In February 2016, we initiated a Phase 1 clinical trial of BGB-290 in combination with BGB-A317. The dose escalation portionchemotherapy -- one in patients with non-squamous NSCLC and the second in patients with squamous NSCLC. We submitted for approval for tislelizumab in China to treat R/R cHL and announced that this submission had been accepted on August 31, 2018, and received priority review on November 15, 2018. We expect to submit for approval in China for the treatment of patients with UC based on the results of the studypivotal Phase 2 trial. If we receive conditional approval instead of full approval, we will be required to conduct one or more confirmatory studies after such conditional approvals. We also expect to submit for approval in China for tislelizumab for the treatment of patients with NSCLC, ESCC, GC and HCC based on our China trials and, where appropriate, our global studies.

Pamiparib (BGB-290), a PARP Inhibitor
Pamiparib is currently enrolling subjects with TNBC, ovarian cancer, fallopian tube cancer, peritoneal cancer, SCLC,an investigational small molecule inhibitor of PARP1 and tumors likely to have DNA damage repair deficiencies susceptible to PARP inhibition or likely to respond toPARP2 that is being evaluated as a PD-1 blockade. In June 2016, we initiated a Phase 1 clinical trial with BGB-3111potential monotherapy and in combination with BGB-A317combinations 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, 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 alsodemonstrated encouraging activity both in relapsed and refractory patients as well as in the maintenance setting. In the United States, in 2018 there were approximately 22,240 new cases of OC, 266,120 new cases of breast cancer, 164,690 new cases of prostate cancer, and 26,240 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 have been exploredapproved by the FDA. 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 settings beyond late lines with encouraging results, suchlate-stage development. In 2017, global sales of the PARP class exceeded US$461 million according to company reports. In China, AstraZeneca received approval for olaparib in August 2018 under priority review that utilized international multi-center data. Zai Labs obtained the development and commercial rights for niraparib in China, and its NDA to the NMPA was accepted in December 2018 for use as maintenance setting. Clinical trials have also shown that PARP inhibitorstherapy in OC. There are active beyond the initial population of patients withBRCA mutations. In ovarian cancer and other cancers, there is growing understanding and increasing clinical data indicating that multiple DNA repair defects or HRD, other thanBRCA mutations could render 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 fromsome other PARP inhibitors in termsbeing developed by domestic Chinese companies, including fluzoparib from Hengrui and Hansoh, but none have been submitted to the NMPA as of brain penetration, selectivity, DNA-trapping activity, and oral bioavailability.

    Brain penetration.February 6, 2019.  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

Data

As of March 20, 2017,November 6, 2018, we have dosedenrolled over 110360 patients in clinical trials of pamiparib, including three registration or registration-enabling clinical trials.
A multi-center, open-label Phase 1/2 trial of pamiparib is being conducted in Australia in patients with BGB-290 in either monotherapy or combination trials. We have completed the dose-escalation phase and are evaluating BGB-290 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 presentedadvanced solid tumors. On September 8, 2017, preliminary clinical data from ourthe ongoing Phase 1 clinical trial.1/2 trial of pamiparib in patients with advanced solid tumors were presented at ESMO. As of June 30, 2015, 29 relapsed or refractory solid tumor1, 2017, 68 patients were enrolled in the trial. The median duration of therapy for all patients was 79 days (range 1 to 926 days). At the time of the data cutoff, 20 patients remained on treatment.

At the time of the data cutoff, 39 patients with epithelial ovarian cancer, or EOC, or associated tumors such as fallopian tube or primary peritoneal cancers, were evaluable for efficacy. Among this group, there were three confirmed CRs, 10 confirmed PRs, and 21 cases of SD. Of the 23 evaluable patients with EOC or other associated tumors known to be BRCA-mutated, there were three CRs, seven cohorts receiving monotherapy BGB-290 in doses ranging from 2.5 mg BID to 80 mg BID. Initial analysisPRs, and 10 cases of data from this trial suggests that BGB-290 is well-tolerated. Few AEs of myelosuppression, no liver toxicity signal,SD. Of the 13 evaluable patients whose BRCA gene types are wild type, there were two PRs. Of the three evaluable patients whose BRCA gene types were unknown, there was one PR. Complete and few drug-related grade 3/4 AEspartial responses 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.

Note: * Table shows only the data presented at 2015 AACR-NCI-EORTC International Conference with data cutoff date of June 30, 2015.

        Proof-of-concept was established, with significant anti-tumor activity seen in ovarian cancer patients starting at the lowest tested dose and data suggestive of a wide therapeutic window. Among 14


evaluable patients with ovarian cancer as of June 30, 2015, seven had an objective response (six PRs and one CR). Of the ten ovarian cancer patients with germ-line BRCA mutation, five had an objective response (four PRs and one CR), and of the three ovarian cancer patients with germ-line BRCA wild-type, two had an objective response (two PRs). The remaining one patient had unknown BRCA status and progressive disease, or PD. When assessed by underlying mutations, of six evaluable patients with the BRAF V600E mutation, there was one CR, one PR and four SDs.


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 likelyknown 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,be platinum-resistant as well as patients with platinum-sensitive urothelial bladder cancer, pancreatic adenocarcinoma, SCLC,disease. There is no guarantee that these results will be reproduced in pivotal trials.

The safety analysis suggested that pamiparib was generally well-tolerated in patients with advanced solid tumors. AEs assessed to be treatment-related occurred in 78% of patients and gastricwere all grade 3 or gastroesophageal junction cancers. Key objectiveslower in severity. The most common treatment-related AEs (≥10% of patients) were nausea (56%), fatigue (40%), anemia (25%), vomiting (21%), diarrhea (21%), decreased appetite (15%), and neutropenia or neutrophil count decrease (12%). SAEs occurred in 46% of patients, and SAEs considered to be treatment-related and occurring in more than one patient included two cases each of nausea and anemia. Four

patients reported dose-limiting toxicity, or DLT. Four patients had a TEAE with a fatal outcome; none were assessed as being treatment-related and all of which were associated with disease progression.
Ovarian Cancer
On April 16, 2018, preliminary clinical data from the trial include assessing safety and tolerability, maximum tolerated dose, recommended Phase 2 dose, pharmacokinetics, and preliminary anti-tumor activity of the BGB-A317 and BGB-290 combination.

        In December 2016, we also initiated aopen-label, multi-center Phase 1 open-label, multi-centerdose-escalation trial with BGB-290 in China. The Phase 1 study is designed to investigate the safety, pharmacokinetics, and antitumor activity of BGB-290pamiparib in Chinese patients with locally advanced solid tumorsor metastatic high-grade non-mucinous ovarian cancer, or HGOC, including fallopian cancer, or triple-negative breast cancer, or TNBC, who had disease progression following at least one line of chemotherapy were presented at the 2018 American Association for Cancer Research Annual Meeting in Chicago, IL.

Patients were dosed at 20 mg, 40 mg, or 60 mg BID. As of September 25, 2017, 15 female patients were enrolled, nine with HGOC and to determinesix with TNBC. Nine patients had received four or more prior lines of therapies. All nine patients with HGOC were platinum-resistant (n=8) or refractory (n=1). Seven patients had a confirmed BRCA1/2 mutation (BRCAm), including five patients with HGOC and two patients with TNBC and the remaining patients had BRCA 1/2 wildtype (BRCA-WT). The median duration of treatment was 2.5 months (range: 8-260 days).
As of September 25, 2017, 13 of the 15 patients were evaluable for antitumor activity; five patients remained on treatment. Two of the nine HGOC patients achieved a confirmed PR including one platinum-refractory patient with BRCA wildtype status and one platinum-resistant patient with BRCA1/2 mutation, six HGOC patients had SD (BRCAm, n=4 and BRCA-WT, n=2) and one patient discontinued before the first radiographic assessment. Of the six treated TNBC patients, five (BRCAm, n=1, BRCA-WT, n=4) experienced disease progression and one patient (BRCAm) discontinued before the first radiographic assessment. Four of these evaluable TNBC patients were BRCA-WT and all experienced disease progression during the previous platinum-based chemotherapy.
The safety analysis suggested that pamiparib was generally well-tolerated. No dose-limiting toxicities were reported across the dose range, with the recommended Phase 2 dose, or RP2D, confirmed as 60 mg BID. Asthenia (n=12) and nausea (n=12) were the most commonly reported TEAE. Severity of all AEs was grade 3 or less. Overall, three patients experienced a serious AE (grade 2 abdominal infection, n=1; grade 3 pleural effusion, n=1; grade 3 ileus, n=1), none of which were considered related to treatment. Two of the SAEs led to treatment withdrawal (abdominal infection, n=1; pleural effusion, n=1).
Glioblastoma Multiforme
On November 16, 2018, we announced data from an open-label, multi-center global Phase 1b/2 multiple-dose and dose-escalation trial of pamiparib plus radiation therapy, or RT, and/or temozolomide, or TMZ, in these patients.

        We planpatients with newly diagnosed or R/R glioblastoma multiforme, or GBM, at the 23rd Annual Scientific Meeting and Education Day of the Society for Neuro-Oncology (SNO). This study was designed to advance BGB-290 into late-stage development. evaluate the safety, efficacy and clinical activity of the combination. Patients with newly diagnosed GBM with unmethylated MGMT (O6-methylguanine-DNA methyltransferase) promoter status (Arm A) received pamiparib (60 mg BID) over escalating time periods (two, four, or six weeks) in combination with RT over six to seven weeks. Patients with R/R GBM (Arm C) received pamiparib (60 mg BID) continuously plus TMZ administered on Days 1 to 21 of each 28-day cycle. After evaluation of safety and tolerability from Arm A and C, Arm B will enroll patients with newly diagnosed GBM and treat them with the triple combination of RT, pamiparib, and TMZ.

As of September 14, 2018, a total of 18 patients with newly diagnosed GBM were enrolled in Arm A (n=3, 6 and 9 in the two-, four-, and six-week cohorts respectively). The median study follow-up duration was 19 weeks (2-54). As of the data cutoff date, 15 of the 18 patients were evaluable for response per modified response assessment in neuro-oncology (mRANO) criteria. Two of 15 patients achieved a PR (one was confirmed) and six patients achieved stable disease (SD); the disease control rate was 53.3% (95% CI: 26.6-78.7). Five grade >3 AE (chills, diarrhea, fatigue, nausea, vertigo, one each, or 5.6%) were considered related to pamiparib or RT. Dose-limiting toxicities of fatigue, vertigo, and chills (one each) were reported. In Arm C, eight patients received TMZ at a fixed dose of 40 mg for 21 of 28 days and seven patients received 20 mg TMZ. The median study follow-up duration was 12.9 weeks (0.3-31.4). Ten of the 15 patients were evaluable per mRANO criteria and there were two PRs (one unconfirmed and one confirmed after data cutoff) and three SD. Grade >3 AEs included anemia (20%), fatigue (13.3%), and decreased lymphocyte count (13.3%), which were considered related to pamiparib or TMZ. Dose-limiting toxicities of nausea and neutropenia were reported. The combination of 21 days of 40 mg TMZ with pamiparib was not tolerable; a lower 20 mg TMZ dose evaluation in combination with pamiparib is ongoing.

Clinical Development Plan

BGB-283,Lifirafenib (BGB-283), a 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, 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 intend 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 be 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 in Australia and New Zealand. We are currently conducting the multi-arm dose-expansion phase of the Phase 1 clinical trial in Australia and New Zealand and in April 2016 completed the enrollment for the dose-expansion phase of our clinical trial for the treatment of solid tumors with BRAF mutations and/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 is 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 kinase is an enzyme that catalyzes the transfer of a phosphate group from a donor molecule to an acceptor. This process often actslifirafenib 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 hasagents may have potential for treating various malignancies, such as melanoma, NSCLC and endometrial cancer. In October 2018, we formed a collaboration with SpringWorks Therapeutics to investigate the potentialcombination of lifirafenib and their MEK inhibitor, PD-0325901, in patients with advanced solid tumors that harbor RAS, RAF mutations and other MAPK pathway aberrations. This study is planned to be differentiated from other drug candidates currently under development and fromcommence in the first quarter of 2019.

Currently approved first-generation BRAF inhibitors due to the following:

    include Roche’s ZELBORAFIncreased inhibitory activity against RAF dimers.® BGB-283's increased inhibitory activity against RAF dimers may potentially address resistances associated with increased RAF dimer formation in response to treatment with first-generation(vemurafenib), Novartis’ TAFINLAR® (dabrafenib) and Array BioPharma's BRAFTOVI® (encorafenib). The combination of BRAF inhibitors. As noted above, most known molecular mechanisms of resistance to RAFand MEK inhibitors induce RAF dimerization. As such, BGB-283's ability to inhibit RAF dimers and target disregulated MAPK pathways resistant to first-generation BRAF inhibitors could result in a clinically significant effect.

    Increased activity in KRAS/NRAS mutated cancers.We believe that BGB-283's RAF dimer activity could translate into anti-tumor activity in KRAS/NRAS mutated cancers. Anti-tumor activities were observed in preclinical KRAS/NRAS mutant cancer models in vivo.

    Increased inhibitory activity against EGFR.  BGB-283 has demonstrated inhibitory activity against EGFR. The reported response rate of vemurafenib in BRAF V600E colorectal cancer is only 5%. Two independent studies suggested that EGFR feedback activation could be one of the main mechanisms of the observed resistance to first-generation BRAF inhibitors. BGB-283 has demonstrated good EGFR inhibitory activity in bothin vitro andin vivo preclinical models. BGB-283's activity against EGFR may help address the EGFR feedback activation observed in BRAF V600E colorectal cancer tumors.

    Differentiated resistance profile.  BGB-283 has shown inhibitory activity against RAF dimers. An increase in RAF dimers has been observed to be a major resistance mechanism to first-generation BRAF inhibitors. A differentiated resistance profile has been observed in preclinical models for BGB-283.

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 of BGB-283approved in patients with BRAF or KRAS/NRAS-mutated cancers at the 2016 American Association for Cancer Research annual conference. AsV600E/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 January 31, 2016, the data cutoff date, among 31 advanced solid tumor patients, the most frequent treatment-related adverse events, or TRAE, were fatigue (52%), thrombocytopenia (39%), decreased appetite (39%), hand-foot syndrome (35%), dermatitis acneiform (32%)several other BRAF inhibitors in clinical development, such as Roche’s belvarafenib and hypertension (32%). The most frequent treatment-related grade 3/4 AEs included thrombocytopenia (13%), fatigue (10%) and liver enzyme elevation (10%).

        We have achieved proof-of-conceptNovartis’ LXH254.

Lifirafenib was evaluated in a range of cancers including those with KRAS and BRAF mutations. At the time of the data cutoff, among 29 patients enrolledmulti-center, open-label Phase 1 trial conducted 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 outcomprised of 105 patients).

        We expect to present data from the Phase 1 dose-expansion study of BGB-283two parts - dose escalation and dose expansion - in patients with BRAF or KRAS/NRAS mutated solid tumors or patients with pancreatic cancer. Lifirafenib demonstrated antitumor activity in an oral presentation on April 2 during a Clinical Trials Plenary Sessionboth BRAF and KRAS-mutated tumors in preclinical studies and in the dose-escalation portion of this Phase 1 trial.

Data from the dose-expansion portion of the trial were presented at the 2017 American Association for Cancer Research, or AACR, Annual Meeting.

The dose-expansion portion of the trial was designed to evaluate the safety and efficacy of lifirafenib at the recommended Phase 2 dose of 30 mg once daily established in the dose-escalation part of the trial. In March 2017,the dose-expansion portion, lifirafenib was generally well-tolerated at a dose of 30 mg once daily and continued to show antitumor activity in patients with BRAF V600-mutated solid tumors and patients with KRAS-mutated solid tumors. The safety analysis, which included 96 patients as of the September 12, 2016 cutoff, suggested that lifirafenib was generally well-tolerated at 30 mg once daily, with most drug-related AEs being grades 1 or 2 in severity. The most frequent drug-related AEs (≥10%) of any grade were fatigue (38.5%), dysphonia (26.0%), decreased appetite (21.9%), palmar-plantar erythrodysesthesia syndrome (21.9%), thrombocytopenia (19.8%), dermatitis acneiform (17.7%), diarrhea (16.7%), rash (16.7%), nausea (15.6%), hypertension (11.5%) and glossodynia (10.4%). The most frequent drug-related grade 3 and 4 AEs (≥ 2%, two patients or more) included fatigue (7.3%), hypertension (6.3%), thrombocytopenia (6.3%), pyrexia (3.1%), hyponatremia (2.1%), anemia (2.1%), neutropenia (2.1%), febrile neutropenia (2.1%), decreased platelet count (2.1%), increased alanine aminotransferase (2.1%), increased GGT (2.1%) and sepsis (2.1%).

The cutoff for the efficacy analysis was September 17, 2016. In seven patients with BRAF V600-mutated melanoma (including one V600K and one V600R) who were naïve to BRAF or MEK inhibitors, there were three PRs and three cases of SD. In three patients with BRAF V600-mutated PTC, there was one PR and two cases of SD. In six patients with KRAS-mutated NSCLC, there was one PR and two cases of SD. In ten patients with solid tumors with BRAF non-V600 mutations or solid tumors with BRAF V600 mutations that are not included in other cohorts, there were two PRs, in one patient with BRAF V600E-mutated melanoma and one with BRAF V600E-mutated OC, and three cases of SD. In two patients with BRAF V600-mutated NSCLC, there was one unconfirmed PR and one case of SD. Additional cases of SD were observed in four of six melanoma patients with BRAF V600-mutated melanoma who had responses to, but developed resistance against, BRAF or MEK inhibitors, nine of 13 patients with BRAF V600-mutated CRC, five of five patients with KRAS-mutated endometrial cancer, 12 of 20 patients with KRAS/NRAS-mutated CRC, and 10 of 21 patients with other KRAS/NRAS-mutated solid tumors or pancreatic cancer. In the Phase 1a portion of the trial, confirmed objective responses included a CR in a patient with BRAF V600E-mutated melanoma and two PRs, one in a patient with BRAF V600E-mutated thyroid cancer and one in a patient with KRAS-mutated endometrial cancer.

BGB-A333, a PD-L1 Inhibitor
BGB-A333 is an investigational humanized IgG1-variant monoclonal antibody against PD-L1, the ligand of PD-1. We intend to develop BGB-A333 either as a monotherapy or in combination with other cancer therapies, such as tislelizumab, to treat various cancers and potentially other areas of unmet need. BGB-A333 is currently being evaluated in a Phase 1 clinical trial in Australia to assess the safety and antitumor effect of BGB-A333 alone and in combination with tislelizumab in patients with advanced solid 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, or TIM-3. We began a Phase 1/2 trial of BGB-A433 in combination with tislelizumab in various solid tumors in the fourth quarter of 2018.
Sitravatinib (MGCD-0516), a Multi-Kinase Inhibitor
In January 2018, we regained the worldwide rights to BGB-283 after Merck KGaA, Darmstadt Germany informed us that it will not exercise the Continuation Option in its formerentered into an exclusive license agreement with 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 commercializetreat patients who are refractory to prior immune checkpoint inhibitor therapy, including a potentially registration-enabling Phase 3 trial of sitravatinib in non-small cell lung cancer projected to initiate in the first half of 2019. Sitravatinib is also being evaluated as a single agent in patients with NSCLC, melanoma and manufacture BGB-283other solid tumor types whose tumors harbor specific genetic alterations in CBL. In recent data readouts by Mirati, sitravatinib has demonstrated durable responses in lung cancer patients who progressed after treatment with checkpoint inhibitors. We began a Phase 1 study of sitravatinib in combination with tislelizumab in various solid tumors in Australia and China in the third quarter of 2018.
Avadomide (CC-122), a Cereblon Modulator
Avadomide (CC-122) is an investigational next-generation Cereblon modulator currently in clinical development by Celgene. It is in multiple Phase 1 and Phase 1/2 clinical trials, both as a single agent and in combination, for hematological and solid tumor cancers outside of China. TheAvadomide (CC-122) has been differentiated from previous compounds (such as thalidomide, lenalidomide and pomalidomide) and has been developed based on the scientific understanding of Cereblon-mediated protein homeostasis. We have rights to develop and commercialize avadomide (CC-122) in China under our exclusive license agreement with Merck KGaA, Darmstadt GermanyCelgene. See “-Celgene Collaboration.”
Our Commercial Products
We commercialize the following cancer drugs in China under an exclusive license from Celgene. Historically, the fourth quarter sales of many oncology drug sales in China are lower than sales levels in the third quarter. Our product ABRAXANE®'s fourth quarter sales were lower than the third quarter in 2018.
ABRAXANE®
ABRAXANE® (paclitaxel albumin-bound particles for injectable suspension) is further detaileda solvent-free chemotherapy product which was developed using Celgene’s proprietary nab® technology platform. This protein-bound chemotherapy agent combines paclitaxel with albumin. Globally, ABRAXANE® is approved for uses in "—Collaborationbreast cancer, NSCLC, pancreatic cancer and GC with Merck KGaA, Darmstadt Germany."

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 compared to solvent-based taxanes in both metastatic breast cancer and neo-adjuvant 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 dozens of generic taxanes. LIPUSU® is currently the market leader with approximately one-third of the market share.
In February 2018, an albumin-bound paclitaxel from CSPC Pharmaceutical Group was approved by the NMPA. Another form of albumin-bound paclitaxel from Hengrui was approved by the NMPA in September 2018.
In 2019, we plan to seek to differentiate and defend ABRAXANE® against growing generic competition in China, expand our sales force footprint and hospital coverage, and improve patient access through critical illness insurance negotiations and provincial reimbursement listings. As of September 1, 2018, ABRAXANE® is listed on provincial reimbursement drug lists of Fujian, Hubei, Ningxia, Jiangsu and Hunan, as well as in critical illness insurance program in Zhejiang and Shandong.
REVLIMID®
REVLIMID® (lenalidomide) is an oral immunomodulatory drug that was approved by the NMPA in China in 2013 for the treatment of multiple myeloma, or MM, in combination with dexamethasone in adult patients who have received at least one prior therapy. On February 2, 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.
MM is a malignant disease whose tumor cells originate in plasma cells in the bone marrow, which are cells in which B-lymphocytes develop to the final functional phase. The World Health Organization currently classifies it as a B-cell lymphoma, also known as plasma cell myeloma/plasmacytoma. MM is characterized by abnormal proliferation of bone marrow plasma cells accompanied by overproduction of monoclonal immunoglobulin. MM is often accompanied by multiple osteolytic lesions, hypercalcemia, anemia, and kidney damage. Due to the inhibition of normal immunoglobulin production, patients are prone to a variety of bacterial infections.
At present, MM is one of the most common malignant tumors in the blood system and occurs frequently in the elderly. The actual incidence increases with age, peaking from 60 to 70 years of age. Men suffer slightly more than women. Globally, the incidence was 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 18,000 new patients in 2017, 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, generic thalidomide 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. The first lenalidomide generic and first bortezomib generic in China were approved in November 2017. Another new agent for R/R MM, NINLARO® (ixazomib), an oral proteasome inhibitor developed by Takeda, received marketing approval from the NMPA on April 12, 2018. In February 2018, generic lenalidomide from ShuangLu Pharmaceutical Company was approved by the NMPA, and a third generic from Yangtze River is under review.
REVLIMID® was listed on the NRDL in June 2017.
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, or MDS, chronic myelomonocyte leukemia, or CMML, and acute myeloid leukemia, or 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, or NCCN, MDS guideline 2013 and MDS Foundation. DNA methylation is an important mechanism of epigenetic gene regulation, but aberrant DNA hypermethylation can result in gene silencing. Silencing of tumor suppressor genes promotes cancer development and progression. MDS patients display aberrant DNA methylation of thousands of genes, which increases with advanced disease and is a poor prognostic factor.
In China, the main treatments for intermediate-2 and high-risk MDS are conventional care regimen, or CCR (best supportive care, low-dose cytarabine and intensive chemotherapy), and hypomethylating agents, or 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 by 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.
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 including a PD-L1 monoclonal antibody, an additional RAF dimer inhibitor, a TIM-3 cell surface protein monoclonal antibody, and a BTK inhibitor for non-oncology indications.agents. We anticipate advancing one or more of our preclinical assets 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 currently have manufacturing capabilities at our research and development center in Beijing and at our manufacturing site in Suzhou, China that may be used for process development and clinical-scale small molecule drugs and biologics, as well as commercial scale production of small molecule drugs at our Suzhou facility. We are also constructing a commercial-scale biologics facility in Guangzhou, China. However, we have not yet begun to manufacture or process, either on our own or through a third-party, our drug candidates on a commercial scale. We currently rely on, and expect to continue to rely on, third-party contract research organization, or CROs, and contract manufacturing organizations, or CMOs, for the supply of raw materials and production of our drug candidates, as described below.
Raw Materials
We 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 CROs and excipients, which are commercially available from well-known vendors that meet the requirements of the relevant regulatory agencies. The core raw material to be used in manufacturing at our Guangzhou facility under construction is expected to be a genetically modified cell line that we co-developed and licensed from Boehringer Ingelheim.
We typically order raw materials on a purchase order basis and do 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 us by our suppliers generally range from 30 to 60 days. Our suppliers are generally not responsible for the defects of our finished products.
Production
We have an approximately 11,000 square meter 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, 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. In January 2018, the facility received a manufacturing license from the Jiangsu Food and Drug Administration, which is required for the commercial manufacture of zanubrutinib in China following NDA approval.
In addition, we have formed a joint venture with Guangzhou GET Technology Development Co., Ltd., an affiliate of Guangzhou Development District, to build a 24,000-liter commercial-scale biologics manufacturing facility in Guangzhou, China. Approximately US$300 million in funding has been committed for the construction of the 100,000 square meter manufacturing site. We contracted with General Electric to acquire its state-of-the-art KUBio™ prefabricated biomanufacturing equipment and commenced construction in 2017. We expect the first phase of the facility to be completed in 2019, and, following regulatory inspection and approval, to be used for commercial-scale production of tislelizumab, if approved.
We also have an approximately 140-square meter manufacturing facility at our research and development facilities in Beijing, China, which produces preclinical and clinical trial materials for some of our small molecule drug candidates.
Manufacturing 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 CMOs we use to manufacture our drugs and drug candidates operate under current good manufacturing practice regulations, or cGMP conditions. cGMP are regulatory requirements for the production of pharmaceuticals that will be used in humans.
Contract Manufacturing Organizations
We outsource to a limited number of external contract manufacturers the production of some drug substances and drug products, and we expect to continue to do so to meet the preclinical, clinical and potential commercial requirements 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 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 external service providers, under which they generally provide services to us on a short-term and project-by-project basis. For example, we have an agreement with a contract manufacturer for clinical supply of zanubrutinib and expect to enter into a commercial supply agreement for zanubrutinib in the future. We have entered into a commercial supply agreement with Boehringer Ingelheim Biopharmaceuticals (China) Ltd., or Boehringer Ingelheim, for our investigational anti-PD-1 antibody therapy, tislelizumab, which will be manufactured at Boehringer Ingelheim’s facility in Shanghai, China as part of a marketing authorization holder, or MAH, trial project pioneered by us and Boehringer Ingelheim. We believe the MAH status will be maintained after the expiration of the MAH pilot program in November 2019, based on confirmation from the relevant governmental authority, and therefore we believe that the expiration of the MAH pilot program will not impact our drug candidates. Under the terms of the commercial supply agreement, Boehringer Ingelheim will manufacture tislelizumab in China under an exclusive multi-year arrangement, with contract extension possible. In addition, we obtained certain preferred rights for future capacity expansion by Boehringer Ingelheim in China. For our commercial products licensed from Celgene, we rely on Celgene and its contract manufacturers outside of China for the supply of those drugs.
Agreements with 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.
Celgene Collaboration
Exclusive License and Collaboration with Merck KGaA, Darmstadt Germany

BGB-283

Agreement

On May 24, 2013,July 5, 2017, we entered into license agreements with Merck KGaA, Darmstadt Germany, which wean Exclusive License and Collaboration Agreement, as amended and restated, with Celgene and its wholly-owned subsidiary, Celgene Switzerland LLC, or Celgene Switzerland, which became effective on December 10, 2013 andAugust 31, 2017, pursuant to which we refer to respectively asgranted the Ex-PRC BRAF Agreement and PRC BRAF Agreement. On October 1, 2015 and December 3, 2015, we further amended the Ex-PRC BRAF Agreement. Pursuant to the Ex-PRC BRAF Agreement and PRC BRAF Agreement (a) we granted to Merck KGaA, Darmstadt GermanyCelgene parties an exclusive license under certain of our intellectual property rightsright to develop and manufacture, and, if Merck KGaA, Darmstadt Germany exercised its Continuation Option (described below), to commercialize and manufacture our compound BGB-283, and any other compound covered by the same existing patent rights with primary activity to inhibit wildtype or certain mutant BRAF, or the Licensed BRAF Inhibitors,tislelizumab in all countriesfields of treatment, other than hematology, in the United States, Europe, Japan and the rest of world excluding The People's Republic of China,other than Asia, which we refer to as the Ex-PRC Territory,PD-1 License Agreement.

Pursuant to the terms of the PD-1 License Agreement, the Celgene parties made upfront payments of US$263 million to us. In addition, pursuant to a share subscription agreement with Celgene Switzerland dated July 5, 2017, or the Share Subscription Agreement, we issued approximately 32.7 million of our ordinary shares on August 31, 2017 for an aggregate purchase price of US$150 million at $4.58 per ordinary share, or $59.55 per ADS, representing a 35% premium to an 11-day volume-weighted average price of our ADSs. The agreement also provides for up to US$980 million in potential development, regulatory and (b) Merck KGaA, Darmstadt Germany grantedsales milestone payments and tiered royalties based on percentages of annual net sales, depending on specified terms, in the low double digit to mid-twenties, with customary reductions in specified circumstances. Royalties are payable on a licensed product-by-product and country-by-country basis until the latest of the expiration of the last valid patent claim, the expiration of regulatory exclusivity, or 12 years after the first commercial sale of such licensed product in the country of sale.
Each party has the right to develop and commercialize tislelizumab in its respective field and territory, and has also agreed to collaborate through a joint steering committee comprised of an equal number of representatives from each party on, among other things, the conduct of up to eight global pivotal clinical trials, or the Basket Studies. Each Basket Study will be conducted and funded by either us an exclusive licenseor Celgene in accordance with a mutually agreed development plan and study design. For any Basket Studies conducted and funded by us, Celgene has the right to opt into such program, at which time it will reimburse us for agreed upon development costs based on a multiple of such costs that varies according to the stage of development at which Celgene opts into the program. Celgene has committed to use commercially reasonable efforts to develop at least one licensed product, to seek specified regulatory approvals and to spend at least US$100 million on development for the Basket Studies led by Celgene, subject to specified conditions. In addition, we retain the right to develop tislelizumab in combination therapies with our portfolio compounds, and Celgene has a right of first negotiation for tislelizumab in the hematology field and in our territory, subject to specified conditions.
The PD-1 License Agreement contains customary representations, warranties and covenants by us and Celgene. Unless earlier terminated, the agreement will expire on a licensed product-by-product and country-by-country basis upon the expiration of the royalty term in such country for such licensed product. The agreement may be terminated by Celgene upon 30 days’ prior written notice, or by either party upon the other party’s bankruptcy or uncured material breach. In addition, the agreement includes standard exclusivity obligations and provisions that are triggered in the event that Celgene acquires or is acquired by a third party with a competing product.
In January 2019, Celgene and Bristol-Myers Squibb, or BMS, announced the proposed acquisition of Celgene by BMS, which is expected to close in the third quarter of 2019, subject to receipt of required approvals. BMS markets the anti-PD-1 inhibitor OPDIVO® (nivolumab). Assuming that the BMS-Celgene transaction closes, we expect that a likely outcome will be that the PD-1 License Agreement will be terminated under certain of its intellectual propertythe exclusivity and related provisions, and we will regain the full rights to develop, manufacturetislelizumab with a termination fee from Celgene. Prior to that time, we expect to continue to conduct the agreed upon development plans under the existing terms of the agreement, including receipt from Celgene of development funding for the Basket Studies that it has agreed to fund. In the event that the PD-1 License Agreement is terminated, we believe that we are operationally and commercialize the Licensed BRAF Inhibitors in The People's Republicfinancially capable of continuing to advance tislelizumab on our own with minimal disruption.
Celgene China Agreements
On July 5, 2017, we and a wholly-owned subsidiary of Celgene, Celgene Logistics Sàrl, or Celgene Logistics, entered into a License and Supply Agreement, which we refer to as the PRC Territory, subjectChina License Agreement and which became effective on August 31, 2017, pursuant 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 to 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 in the PRC Territory.

        The term of the PRC BRAF Agreement continues unless terminated as permitted by either party. Under the PRC BRAF Agreement, Merck KGaA haswere granted the right to terminate due to our uncured breach or voluntarily upon prior written notice. 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 Agreementexclusively distribute 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 developpromote Celgene’s approved cancer therapies, ABRAXANE®, REVLIMID® and manufacture,VIDAZA®, and its investigational agent avadomide (CC-122) in clinical development in China, excluding Hong Kong, Macau and Taiwan. In addition, if Merck KGaA, Darmstadt Germany exercised a continuation option,Celgene decides 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,a new oncology product through a third-party 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,licensed territory during the option period. The Ex-PRC PARP Agreement was terminated, except for certain provisions therein that are needed to effectuate the continuationfirst five years of the PRC PARP Agreement, including those provisions that were required in the event that Merck KGaA, Darmstadt Germany exercised its PRC Commercialization Option (described below).

        Pursuant to the PRC PARP Agreement, ifterm, we fail to achieve national priority project status in the PRC Territory under its 12th or 13th five-year plan with respect to our BGB-290 PARP program in the PRC Territory by July 28, 2017, Merck KGaA, Darmstadt Germany can exercise its option to acquire exclusive commercialization rights under the BGB-290 PARP program in the PRC Territory, which we refer to as the PRC Commercialization Option. If, however, we do achieve national priority by July 28, 2017, Merck KGaA, Darmstadt Germany only hashave a right of first negotiation to acquire exclusive commercialization rights underobtain the BGB-290 PARP programright to commercialize the product, subject to certain conditions. We paid an aggregate of US$4.5 million in cash for the PRC Territorylicense and our acquisition of Celgene Shanghai, as described below.

The term of the China License Agreement is 10 years and may be terminated by either party upon written notice in the event we seek to license our intellectual property rights to a thirdof uncured material breach or bankruptcy of the other party, therein.

        Underor if the Ex-PRC and PRC PARP Agreements, in November 2013 we received $6 million in non-refundable payments and in 2014 $9 million in milestone payments. We are eligible to receive up to $7 million and $2.5 million, respectively, in payments upon the successful achievement of pre-specified clinical andunderlying regulatory milestones in the PRC Territory. In addition, if Merck KGaA, Darmstadt Germany exercises the 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 achievement of a certain additional regulatory event in the PRC Territory.

        Under the PRC PARP Agreement, in considerationapprovals for the licenses granted to us, wecovered products are required to pay Merck KGaA, Darmstadt Germany a high single-digit royalty on aggregate net sales of Licensed PARP Inhibitors in the PRC Territory.

        The PRC PARP Agreement continues unless terminated as permitted by either party. Merck KGaA, Darmstadt Germanyrevoked. Celgene Logistics also has the right to terminate duethe agreement with respect to our uncured breach or for convenienceREVLIMID® at any time upon prior written notice. We havenotice to the rightCompany under certain circumstances.

In the event of an acquisition of Celgene Logistics by another party, the China License Agreement provides that Celgene Logistics shall provide notice to terminate these agreements due to Merck KGaA, Darmstadt Germany's uncured breach or forus, and within a specified period of time, requires that the parties discuss in good faith any challenge brought against our licensed patent rights.

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:

    Potential for more rapid approvalchanges in the world's second largest commercial market,supply requirements of the China dueLicense Agreement that Celgene Logistics may request as a result of the acquisition. During that period, the China License Agreement requires us to conduct business in the ordinary course and provides that Celgene Logistics is not required to supply more than a separate regulatory framework for locally developed drug candidates. This pathway to approval createsspecified amount more than the potential foramount of our drug candidatesforecasted

demand. We expect to be first-in-class locally and to obtain approval in China prior to ex-China developed candidates. By developing our compounds preclinically and manufacturing them in China, we have the ability to seek product approval from the CFDA as a domestic Category 1 drug. This domestic Category 1 designation allows us to use a distinct route for bringing our products to market compared to the Category 5 regulatory process available to multinational companies with drugs approved for marketing by major foreign drug regulatory authorities, such as the FDA or EMA. We believe the Category 1 regulatory pathway will allow us to provide patients in China more rapid access to safe and effective cancer therapies.

    The opportunity to supplement and accelerate global clinical development by accessing the Category 1 China local regulatory path for locally developed drug candidates to enable more rapid clinical trial enrollment from a pool of approximately 20—25% of the world's cancer patients. The prevalence rates for some cancers, such as lung, gastric, hepatic and esophageal are higher in China, and for others, such as breast and cervical, are lower.

    Currently, many global standard-of-care therapies are not approved or available in China, resulting in a significant need for innovative therapeutics with strong efficacy and safety profiles. As a result, we believe there is a higher likelihood that drug candidates that have demonstrated proof-of-concept in the clinic and become qualified for the Category 1 regulatory pathway will receive regulatory approval in China.

        We believe our strategy and approach is aligned with the Chinese government's policies, and we intendable to continue to work with local authorities to bring innovative therapeutics to patientsmarket ABRAXANE®, REVLIMID® and VIDAZA® in China as quickly as possible.

        Inunder the China License Agreement following the closing of the announced BMS acquisition of Celgene, if that transaction occurs.

The China License Agreement contains customary representations and warranties and confidentiality and mutual indemnification provisions.
On August 2015,31, 2017, our wholly owned subsidiary, BeiGene (Hong Kong) Co., Ltd., acquired 100% of 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:

    A plan to accelerate innovative drug approval with a special review and approval process, with a focus on areasequity interests of high unmet medical needs, including drugs for HIV, cancer, serious infectious diseases, orphan diseases and drugs on national priority lists.

    A plan to adopt a policy which would allow companies to act as the marketing authorization holder and to hire contract manufacturing organizations to produce drug products.

    A plan to improve the review and approval of clinical trials, and to allow companies to conduct clinical trials at the same time as they are in other countries and encourage local clinical trial organizations to participate in international multi-center clinical trials.

        In November 2015, the CFDA releasedCircular Concerning Several Policies on Drug Registration Review and ApprovalCelgene Pharmaceutical (Shanghai) Co., Ltd., or Celgene Shanghai, a wholly-owned subsidiary of Celgene Holdings East Corporation established under the No. 230 Circular, which further clarified the following policies potentially simplifyinglaws of China. The purchase price of Celgene Shanghai was determined to be approximately US$28.1 million from an accounting perspective, and accelerating the approval process of clinical trials:

    A one-time umbrella approval procedure allowing approval of all phasescomprised of a new drug's clinical trials at once, rather than the current phase-by-phase approval procedure, will be adopted for new drugs' clinical trial application.

    A fast track drug registration or clinical trial approval pathway will be available for the following applications: (1) registrationcash consideration of innovative new drugs treating HIV, cancer, serious infectious diseasesUS$4.5 million and orphan diseases; (2) registrationnon-cash consideration of pediatric drugs; (3) registration of geriatric drugs and drugs treating China-prevalent diseases; (4) registration of drugs sponsored by national science and technology grants; (5) registration of innovative drugs using advanced technology, using innovative treatment methods, or having distinctive clinical benefits; (6) registration of foreign innovative drugsUS$23.6 million. The amount allocated to be manufactured locally in China; (7) concurrent applications for new drug clinical trials which are already approved in the United States or European Union or concurrent drug registration applications for drugs which have applied for marketing authorization and passed onsite inspections in the United States or European Union and are manufactured using the same production line in China; and (8) clinical trial applications for drugs with urgent clinical need and patent expiry within three years, and marketing authorization applications for drugs with urgent clinical need and patent expiry within one year.

        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:

    A fast track drug registration or clinical trial approval pathway will be available for the following drug registration applications with distinctive clinical benefits: (1) registration of innovative drugs not sold within or outside China; (2) registration of innovative drug transferred to be manufactured in China; (3) registration of drugs using advanced technology, using innovative treatment methods, or having distinctive treatment advantages; (4) clinical trial applications for drugs with patent expiry within three years, and marketing authorization applications for drugs with patent expiry within one year; (5) concurrent applications for new drug clinical trials which are already approved in the United States or European Union, or concurrent drug registration applications for drugs which have applied for marketing authorization and passed onsite inspections in the United States or European Union and are manufactured using the same production line in China; (6) traditional Chinese medicines (including ethnic medicines) with clear position in prevention and treatment of serious diseases; and (7) registration of new drugs sponsored by national key technology projects or national key development projects.

    A fast track drug registration approval pathway will be available for the following drugs registration application with distinctive clinical benefits for prevention and treatment of HIV, phthisis, virus hepatitis, orphan diseases, cancer, children's diseases, and geriatrics.

        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 packagenon-cash consideration, related 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, datadiscount on ordinary shares issued 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 afforded to us by basing our research and development operations in China, we see an attractive and growing commercial oncology opportunity in our home market. We continue to retain commercial rights in China for all four of our clinical programs and all preclinical programs.


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:

    An aging population, modern diet, lack of exercise and environmental issues that are increasing the prevalence of chronic diseases.

    Increases in disease awareness, diagnostics and treatment rates.

    The continuous and rapid increase of personal disposable income and the establishment of basic national health insurance coverage; making health care accessible to more patients.

        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 incurredCelgene in connection with treating major illnessesthe Share Subscription Agreement 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 withwas 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 affordabilityresult 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 2,172increase 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:

    Rapidly advance our pipeline programs through global development.  In the next 12 months, we plan to make significant advances within our clinical-stage pipeline. We have initiated global and China pivotal trials with BGB-3111, and moved our three other clinical-stage drug candidates into the clinic in China and into the dose-expansion phases of their respective clinical trials in other parts of the world. We will continue to enroll multiple expansion cohorts and significantly increase the number of sites globally participating in these trials. We plan to present data from these trials at medical conferences in 2017. We also have a robust pipeline of preclinical programs and are planning to advance one or more of these programs into the clinic in the next 12 months.

    Pursue global development of combination therapies.  We believe our ownership of both molecularly targeted and immuno-oncology drugs puts us in an advantageous position to develop potentially best-in-combination or first-in-combination therapies that could produce high rates of more durable responses in patients. We have four clinical-stage, independently discovered drug candidates in important and combinable molecularly targeted and immuno-oncology drug classes including BTK inhibitor, PD-1 inhibitor, PARP inhibitor and RAF dimer inhibitor. We believe that 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 clinical stage, a PARP inhibitor and PD-1 inhibitor or a BRAF inhibitor and PD-1 inhibitor for use as combination therapies. In addition to monotherapy trials, we have initiated and are planning combination trials using our wholly-owned drug candidates as well as third-party agents. For BGB-3111, in January 2016 we initiated a combination clinical trial with the anti-CD20 antibody, obinutuzumab, and the trial is currently in the dose-expansion phase. In June 2016, we initiated a combination clinical trial with BGB-A317 for the treatment of various B-cell malignancies. For BGB-290, in February 2016, we initiated a combination clinical trial with BGB-A317. We plan to present data from these combination trials at medical conferences in 2017.

    Continue to use our cancer biology platform to discover additional candidates with best-in-class characteristics and potential for use in rational combinations. We plan to use our cancer biology platform to discover additional drug candidates with the potential to be best-in-class monotherapies and also important components of multiple-agent combination regimens. In the last six years, we have been successful in discovering four clinical stage and several promising preclinical drug candidates. By further investing in and improving our cancer biology platform, we expect that the platform will continue to help us select relevant drug targets, identify potential best-in-class drug candidates and develop regimens for rational drug combinations.

    Bring transformative oncology therapeutics to our home market in China.  We are committed to addressing the needs of cancer patients in our home market. China is one of the largest and

      fastest growing markets for cancer drugs worldwide, representing approximately 20–25% of the world's cancer population and an even greater proportion in lung, liver, and gastric cancers. Because many global standard-of-care therapies are not currently approved and available in China, there is a significant unmet need for innovative cancer drugs for patients who are naive to such treatments. In addition, focusing on cancer types of high prevalence in China will aid our global development efforts in these indications. We have initiated clinical trials in China for each of our four clinical-stage drug candidates to develop them through the locally developed, Category 1 registration pathway. We plan to pursue accelerated development, single-arm registration studies and brief dose-escalation studies in China. We also strive to have our drug candidates selected and listed as national priorities. The ability to launch our cancer drugs in our home market, which has a large patient population, will help us establish broad safety and efficacy profiles for each drug, enabling us to build a full portfolio for future drug combinations.

    Maintain our culture as we grow our business globally.  We believe our science-driven, cooperative and non-hierarchical culture is a key strength of our organization and will continue to be instrumental to our success. As an innovative biotechnology company with research facilities in China, we have been able to attract an internationally trained research team. Many members of our team moved back to China from other countries to join us because they share our goals of advancing the discovery and development of drugs in China and of working with Chinese clinicians to treat their patients with innovative and effective drugs not currently available to them. We intend to maintain our patient-focused and research-driven culture as we discover and develop new drugs for China and the rest of the world.

Intellectual Property

The proprietary nature of, and protection for, our 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 certain of our 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,February 11, 2019, we own eightowned 18 issued U.S. patents, and eight10 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, 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.

The patent portfolios for our four leading productlater-stage clinical drug candidates as of March 21, 2017February 11, 2019, are summarized below:

BGB-3111.Zanubrutinib. We own two issued U.S. patents, one issued China patent, a number of pending PCT and U.S. patent one pending U.S. patent application, two PCT, applications, and corresponding patent applications in other jurisdictions directed to BGB-3111,zanubrutinib, a small molecule BTK inhibitor, combinations of zanubrutinib with other therapeutic agents, and its use for the treatment of hematological malignancies.malignancies or autoimmune disease. The expected expiration for the issued U.S. patents and the issued China patent is 2034, excluding any additional term for patent term extensions. Any patents that may issue from the currently pending U.S. patent applications would be expected to expire in 2034, 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 2037. We intend to pursue marketing exclusivity periods that are available under regulatory provisions in certain countries

.
BGB-A317.Tislelizumab. We are the owner ofown three issued U.S. patents, one issued U.S.China patent, one pending U.S. application, one pending PCT, application,U.S. and China patent applications, and corresponding pending patent applications in other jurisdictions directed to BGB-A317,tislelizumab, a humanized monoclonal antibody against PD-1, and its use for the treatment of cancer. The expected expiration for the issued U.S. patents and the issued China 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.Pamiparib. We own three issued U.S. patents, one issued U.S.China patent, one pending U.S. patent application, and twoa number of pending PCT, U.S. and China patent applications, and corresponding pending patent applications in other jurisdictions directed to BGB-290,pamiparib, 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. patents and the issued China 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.Lifirafenib. We own onetwo issued U.S. patent, one pending U.S. patent application, andpatents, two issued China patents, a number of pending PCT, U.S. and China patent applications, and corresponding pending patent applications in other jurisdictions directed to BGB-283,lifirafenib, 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. patentpatents and the issued China patents 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.

The patent portfolios for our three in-licensed commercial products in China are summarized below:

ABRAXANE®. We are the exclusive licensee of five issued Chinese patents and a number of pending Chinese patent applications directed to ABRAXANE®, a nanoparticle albumin-bound paclitaxel, covering its composition, liquid formulation, and use for the treatment of cancer. Two of the five issued Chinese patents expired in 2018. The expected expirations for the other three issued Chinese patents are 2021, 2026 and 2031, respectively, excluding any additional term for patent term extensions. However, generic versions of albumin-bound palclitaxel have been approved in China and are being commercialized.
REVLIMID®. We are the exclusive licensee of seven issued Chinese patents directed to REVLIMID® (lenalidomide), covering its use for the treatment of cancer, including MM. The expected expirations for the issued Chinese patents are 2023 and 2027, respectively, excluding any additional term for patent term extensions. However, generic versions of lenalidomide have been approved in China and are being commercialized.
VIDAZA®. We do not have any rights in any issued China patent or pending China patent applications directed to VIDAZA®, a chemical analog of cytidine, and its use for the treatment of cancer. We are aware of third parties who are seeking to develop and obtain approval for generic forms of this drug.
Furthermore, although various extensions may be available, the life of a patent and the protection it affords, is limited. As noted above, ABRAXANE®, REVLIMID® and VIDAZA® face or are expected to face competition from generic medications, and we may face similar competition for any approved drug candidates even if we successfully obtain patent protection once the patent life has expired for the drug. The scope, validity or enforceability of our patents may be challenged 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. Under our license agreement with Celgene, Celgene retains the responsibility for, but is not obligated, to prosecute, defend and enforce the patents for these in-licensed products. As such, any issued patents may not protect us from generic competition for these 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, 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 the FDA regulatory review period. 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 we have confidence in these individuals, organizations and systems, agreements or security measures may be breached and we may not have adequate remedies for any breach. In addition, 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-how and inventions.

        Our commercial success will also depend in part on not infringing the proprietary rights of 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 applications 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 useown a number of unregisteredregistered trademarks and pending trademark applications. We currently have registered trademarks for BeiGene and our corporate logo in China, the European Union and other jurisdictions and are seeking trademark protection for BeiGene, our corporate logo, product names and logos, and other marks in jurisdictionsthe United States and other countries 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. Clovis Oncology's rucaparib is currently in Phase 3 trials as a maintenance treatment in patients with platinum-sensitive, high-grade serous or endometrioid epithelial ovarian, primary peritoneal or fallopian tube cancer and as a second line treatment in patients with metastatic castration-resistant prostate cancer and homologous recombination gene deficiency. 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. 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, and its implementing regulations, and biologics under the FDCA, its implementing regulations, and the Public Health Service Act, or 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 , or GMP, regulations;

submission to the FDA of an investigational new drug, or 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 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,institutional review board, or 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, the objectives of the clinical trial, dosing procedures, subject selection and exclusion criteria, and the parameters to be used to monitor subject safety.

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 at geographically dispersed clinical trial sites.population. These clinical trials are intended to establishevaluate the overall risk/benefit relationship of the product and provide an adequate basis for product labelling.labeling.

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. 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.

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; 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, or REMS, plan 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.

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.

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 design of the clinical trials is as efficient as practicable.

criteria for breakthrough therapy designation.

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.

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.

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

periods.

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, or ODD, 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 StatesU.S. 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 ODD 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 on June 29, 2016, July 20, 2016, 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.

June 23, 2016, respectively.

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, 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. 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, theor 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 proposal for fiscal year 2019 contains further drug price control measures that could be enacted during the 2019 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 and reduce the out of pocket costs of drug products paid by consumers. The U.S. Department of Health and Human Services, or 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. For example, in September 2018, CMS announced that it will allow Medicare Advantage Plans the option to use step therapy for Part B drugs beginning January 1, 2019, and in October 2018, CMS proposed a new rule that would require direct-to-consumer television advertisements of prescription drugs and biological products, for which we receive regulatory approval for commercial sale may suffer ifpayment is available through or under Medicare or Medicaid, to include in the government and third-party payors fail to provide adequate coverage and reimbursement.advertisement the Wholesale Acquisition Cost, or list price, of that drug or biological product. In addition, CMS issued an increasing emphasis on cost containment measuresAdvanced Notice of Proposed Rulemaking, or ANPRM, in October 2018 indicating it is considering issuing a proposed rule in the United States has increasedspring of 2019 on a model called the International Pricing Index, or IPI. This model would utilize a basket of other countries’ prices as a reference for the Medicare program to use in reimbursing for drugs covered under Part B. The ANPRM also included an updated version of the Competitive Acquisition Program, or CAP, as an alternative to current “buy and we expectbill” payment methods for Part B drugs. Such a proposed rule could limit our product pricing and have material adverse effects on our business. Although a number of these, and other proposed measures will require authorization through additional legislation to become effective, Congress and the current 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, 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 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 or fraudulent, orfraudulent; making 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, or HIPAA, which created new federal criminal statutes that prohibitprohibits knowingly and willfully executing, or attempting 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.

        The Similarly, state privacy laws may be broader and require greater protections than HIPAA.

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 False Claims Act prohibits anyone from, among other things, knowingly presenting, or causing to be presented, for payment to federaland state healthcare programs (includingsuch as Medicare 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"Medicaid and debarment from contracting with 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 marketing of our products, are subject to scrutiny under this law. For example, pharmaceutical companies have been prosecuted under the 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 federal healthcare programs, and, although 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 as well as under the false claims laws of several states.

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 provision 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.

PRC Regulation

In the People's Republic of China, or 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

PRC Drug Regulation
Introduction
China heavily regulates the development, approval, manufacturing and distribution of drugs, including biologics. The specific regulatory requirements applicable depend on whether the drug is made and finished in China, which is referred to as a domestically manufactured drug, or made abroad and imported into China in finished form, which is referred to as an imported drug, as well as the approval or “registration” category of the drug. For both imported and domestically manufactured drugs, China typically requires regulatory approval for a clinical trial, or CTA, prior to submitting an application for marketing approval. For a domestically manufactured drug, there is also a requirement to have a drug manufacturing license for a facility in China.
In 2017, the drug regulatory system entered a new and significant period of reform. The State Council and the China Communist Party jointly issued the Opinion on Deepening the Reform of the Regulatory Approval System to Encourage Innovation in Drugs and Medical Devices, or the Innovation Opinion. The expedited programs and other advantages under this and other recent reforms encourage drug manufacturers to seek marketing approval in China first, manufacture domestically, and develop drugs in high priority disease areas, such as oncology.
To implement the regulatory reform introduced by the Innovation Opinion, the NMPA has been revising the fundamental laws, regulations and rules regulating pharmaceutical products and the industry, which include the framework law known as the PRC Drug Administration Law, or DAL. The DAL is also generally implemented by a set of regulations issued by the State Council referred to as the DAL Implementing Regulation. The NMPA has its own set of regulations implementing the DAL; the primary one governing clinical trial applications, marketing approval, and license renewal and amendment is known as the Drug Registration Regulation. Although the NMPA made progress in 2018 on different proposals, finalizing several guidelines and documents, as of January 2019 final implementing regulations for many of the reforms in the Innovation Opinion had not been announced, and therefore, the details regarding the implementation of the regulatory changes remained uncertain in some respects.
Regulatory Authorities and Recent Government Reorganization
In the PRC, the NMPA is the primary regulator for pharmaceutical products and businesses. The agency was newly formed from the prior China Food and Drug Administration,

        In or CFDA, in 2018 as part of a complete government reorganization. NMPA is no longer an independent agency. Its parent agency is now the PRC,newly organized State Administration for Market Regulation (SAMR), into which agencies responsible for, among other areas, consumer protection, advertising, anticorruption, pricing, fair competition and intellectual property have been merged.

Like the CFDA, monitorsthe NMPA is still the chief drug regulatory agency and supervisesimplements the administrationsame laws, regulations, rules, and guidelines as the CFDA, and it regulates almost all of the key stages of the life-cycle of pharmaceutical products, as well as medical devicesincluding nonclinical studies, clinical trials, marketing approvals, manufacturing, advertising and equipment.promotion, distribution, and pharmacovigilance (i.e., post-marketing safety reporting obligations). The CFDA's primary responsibility includes evaluating, registeringCenter for Drug Evaluation, or CDE, which remains under the NMPA, conducts the technical evaluation of each drug and approving new drugs, generic drugs, imported drugsbiologic application for safety 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. effectiveness.
The local provincial drug administrative authorities are responsible for supervision and administration of drugs within their respective administrative regions.

        The PRC Drug Administration Law promulgatedNational Health Commission, or NHC, (formerly known by the Standing Committee of the National People's Congress in 1984 and the Implementing Measures of the PRC Drug Administration Law promulgated bynames: the Ministry of Health or(MOH) and National Health and Family Planning Commission (NHFPC)), is China’s chief healthcare regulator. It is primarily responsible for overseeing the MOH, in 1989 set forth the legal framework for the administration of pharmaceutical products, including 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 strengthen the supervision and administration of pharmaceutical products and to ensure the quality and safety of those products for


human use. The revised PRC Drug Administration Law applies to entities and individuals engaged in the development, production, trade, application, supervision and administration of pharmaceutical products. It regulates and prescribes a framework for the administration of pharmaceutical preparationsoperation of medical institutions, which also serve as clinical trial sites, and forregulating the development, research, manufacturing, distribution, packaging, pricinglicensure of hospitals and advertisingother medical personnel. 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 process for pharmaceutical products. This is the chief way that public hospitals and their internal pharmacies acquire drugs.

Also, as part of the 2018 reorganization, the PRC government formed a new State Medical Insurance Bureau which focuses on regulating reimbursement under the state-sponsored insurance plans.

Preclinical and Clinical Development
The amendment of PRC Drug Administration LawNMPA requires preclinical data to support registration applications for imported and domestic drugs. Preclinical work, including pharmacology and toxicology studies, must meet the GLP, issued in January 2017 removedJuly 2017. The NMPA accredits GLP labs and requires that nonclinical studies on chemical drug substances and preparations and biologics that are not yet marketed in China be conducted there. There are no approvals required from the preview procedure atNMPA to conduct preclinical studies.
Registration Categories
Prior to engaging with the provincial levelNMPA on research and development and approval, an applicant will need to determine the registration category for qualification approval ofits drug candidate (which will ultimately need to be confirmed with the NMPA), which will determine the requirements for its clinical trial institutions. Revised Implementing Measures of the PRC Drug Administration Law promulgated by the State Council took effect in September 2002 and was most recently amended in February 2016, providing detailed implementing regulationsmarketing application. There are five categories for the revised PRC Drug Administration Law. The Revised Implementing Measures removed the obtainment of Drug Manufacturing License or a Drug Distribution License as a precondition for incorporation 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 and production of new drugs.

Good Laboratories Practice Certification for Preclinical Research

        To improve the quality of preclinical research, the CFDA promulgated the Administrative Measures for Good Laboratories Practice of Preclinical Laboratory in 2003 and began to conduct 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 equipment and facilities and its operation and management of preclinical pharmaceutical projects. If all requirements are met, a GLP Certification will be issued by the CFDA and the result will be published on the CFDA's website.

        Currently for 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 by 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 for clinical trials 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 Examination and Approval for Domesticsmall molecule drugs: Category 1 Pharmaceutical Products

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

        According(“innovative drugs”) refers 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, namelydrugs that have a new chemical medicine, biological product, or traditional Chinese or natural medicine. A Category 1 drug is a new


drugentity that has nevernot been marketed anywhere in any country. Allthe world, Category 2 (“improved new drugs”) refers to drugs with a new indication, dosage form, route of our clinical-stage drug candidates qualify as domestic Category 1 new drugs.

        According to Provisions onadministration, combination, or certain formulation changes not approved in the Administration of Special Examinationworld, Categories 3 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). 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, respectively, and bring therapiesCategory 5 refers to patients more quickly.

The Advantages of Category 1 New Drugs over Imported Drugs

        Importedinnovative or generic drugs are drugs manufactured outside China. Drugs whichthat have already been marketed abroad by multinational companies, but are not yet approved in China are required to(i.e., many imported drugs).

Therapeutic biologics follow the process applicable to imported drugs in registration. Compareda similar categorization, with the application for imported drugs, the application for Category 1 domesticbeing 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 CTA and marketing approval.
Expedited Programs
Priority Evaluation and Approval Programs to Encourage Innovation
The NMPA has a more straight-forward registration pathway. According to Provisions for Drug Registration, where a special examinationadopted several expedited review and approval treatment is granted, the applicationmechanisms since 2009 and created additional expedited programs in recent years that are intended to encourage innovation. Applications for clinical trial and manufacturing will be handled with priority and with enhanced communication with the Center for Drug Evaluation of the CFDA, or the CDE, which will establish a working mechanism for communicating with the applicants. If it becomes necessary 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 onlythese expedited programs can be submitted after a company obtains an NDA approval and receive the CPP grantedCTA is admitted for review 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 the registration applications for all fourCDE. Some of them 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 to 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:

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 China;the US, EU and (8)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 must be approved and conducted at hospitals accredited by the NMPA. For imported drugs, proof of foreign approval is required prior to the trial, unless the drug has never been approved anywhere in the world. In addition to a standalone China trial to support development, imported drug applicants may establish a site in China that is part of an international multicenter trial, or 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 recently decided to permit those drugs to conduct development via an IMCT as well.
In 2015, the NMPA began to issue an umbrella approval for all phases (typically three) of a new drug clinical trial, instead of issuing approval phase by phase. For certain types of new drug candidates, clinical trial applications may be prioritized over other applications, and put in a separate expedited queue for approval. Category 1 drugs with urgent clinical need and patent expiry within three years, and marketing authorization applicationsare new drug trials which would qualify for drugs with urgent clinical need and patent expiry within one year.

        In February 2016,this expedited umbrella approval status. Other trials that are not part of these expedited lines could still wait up to a year for approval to conduct the CFDA released theOpinions on Priority Review and Approvaltrial.

The NMPA has now also adopted a notification system 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 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 recognizedTrials can proceed if after 60 business days, the applicant has not received any objections from the CDE, as "12-5 Major New Drugs Development Projects" and received government subsidiesopposed to the lengthier previous clinical trial pre-approval process in which the applicant had to wait for affirmative approval. China is also expanding the number of RMB 6,554,600 duringtrial sites by truncating the periodtimeline for accreditation by converting it from January 1, 2013a pre-approval procedure into a notification procedure.

Human Genetic Resources Approval
According 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 StateInterim Measures for the Administration of Taxation,Human Genetic Resources, an additional approval is required for any foreign companies or SAT,foreign affiliates that conduct trials in China. Prior to entering into a clinical trial agreement and beginning a trial, the foreign sponsor and the Chinese clinical trial site are required to obtain human genetic resources, or HGR, approval to collect any biological samples that contain the genetic material of Chinese human subjects from the Ministry of Science and Technology, and any cross-border transfer of the samples or MOSTassociated data requires additional approval. Furthermore, one of the key review points for the HGR review and approval process is the IP sharing arrangement between Chinese and foreign parties. The parties are required to share patent rights to inventions arising from the samples. Conducting a clinical trial in China without obtaining the relevant HGR preapproval will subject the sponsor and trial site to administrative liability, including confiscation of HGR samples and associated data, and administrative fines.


Trial Exemptions and Acceptance of Foreign Data
The NMPA may reduce requirements for trials and data, depending on the drug and the Ministryexisting data. The NMPA has granted waivers for all or part of Finance,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, or MOF jointly issued theAdministrative Rules Guidance Principles, as one of the implementing 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.

        PursuantInnovation Opinion. According to the Temporary RegulationsGuidance Principles, the data of foreign clinical trials must meet the authenticity, completeness and accuracy requirements and such data must be obtained consistent with the relevant requirements under the Good Clinical Trial Practice (GCP) of the International Conference on Business Tax,Harmonisation 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 inside 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 and that i) prevent or treat orphan diseases, ii) prevent or treat serious life-threatening illnesses for which were promulgated bythere is either no effective therapy in China, or for which 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 generallyforeign-approved drug would have clear clinical advantages. Applicants will be 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 developmentestablish a risk mitigation plan and transfer, such business tax may be exempted subjectrequired to approval bycomplete trials in China after the relevant tax authorities.

        In November 2011, the MOFdrug is marketed. The CDE has developed a list of qualifying drugs that meet this criteria.

Clinical Trial Process 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,Good Clinical Practices
Typically drug clinical trials 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.China have three phases. Phase 1 refers to the initial clinical pharmacology and human safety evaluation studies in humans.studies. Phase 2 refers to the preliminary evaluation of a drug candidate'scandidate’s therapeutic effectivenessefficacy and safety for particulartarget indication(s) in patients, provide evidence and support for the design ofpatients. Phase 3 clinical trial, and settle(often the administrative dose regimen. Phase 3pivotal study) refers to clinical trials undertaken to confirm the therapeutic effectiveness of a drug. Phase 3 is used to further verify the drug'sdrug candidate’s therapeutic effectivenessefficacy 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 a drug registration application. Phase 4 refersThe NMPA requires that the different phases of clinical trials in China receive ethics committee approval prior to a new drug's post-marketing studyapproval of the CTA and comply with GCP. The NMPA conducts inspections to assess GCP compliance and will cancel the CTA if it finds substantial issues.

Generic small molecule drugs are required to conduct a bioequivalence trial, in vitro studies or in some cases a clinical trial to demonstrate therapeutic effectivenessequivalence 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 adverse reactions when the drug is widely used, to evaluate overall benefit-risk relationshipsit released a first installment of the drug when used among general population or specific groups, and to adjust the administration dose, etc.

a Marketed Drug List (China’s “Orange Book”) with information about drugs that may serve as reference products.

New Drug Application

        When Phases 1, 2 (NDA) and 3Approval

Upon completion of the clinical trials, have been completed,a sponsor may submit clinical trial data to support marketing approval for the drug. For imported drugs, this means issuance of an import license. Again, the applicant must applysubmit evidence of foreign approval, unless it is an innovative drug that has never been approved anywhere in the world.
NDA sponsors must submit data derived from domestically manufactured drugs in support of a drug approval. Under the current regime, upon approval of the registration application, the NMPA will first issue a new drug certificate to the CFDAapplicant. Only when the applicant is equipped with relevant manufacturing capability will the NMPA issue a Drug Approval Serial Number, which is effectively the marketing approval allowing the holder to market/commercialize the drug in China.
China has recently implemented a Drug Marketing Authorization Holder Mechanism. The MAH pilot program permits research institutions and individual entities to develop and hold the marketing approvals for approvaldrugs without holding a drug manufacturing license. Domestically established research institutions (including domestic companies) can apply through an MAH pilot program if they are established in one of 10 designated provinces (including Beijing and Shanghai), which is now being expanded nationwide in China. The MAHs may engage contract manufacturers and distributors.
The MAH program was originally set up as a pilot program until November 2018. China has now that stated it will expand the program nationwide and make it permanent. Implementing legislation has been proposed, and the MAH pilot has been renewed for one more year until November 2019 in the interim. The Innovation Opinion indicates that China will strive to implement the MAH system nationally as soon as possible by amending the DAL. The NMPA has proposed revisions to accomplish this purpose, but the timeline to finalize these proposals is still unclear.

Manufacturing and Distribution
According to the DAL, 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. A separate certification of compliance with GMP is also required.
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, a separate certification of compliance with NMPA’s drug good supply practice, or GSP, is required.
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
The manufacturer or marketing authorization holder of a NDA.drug is primarily 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 CFDA then determines whetherdefinition of an advertisement is very broad, and does not 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
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 for the establishment of a 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.
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 Linkage
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 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 accordingpending resolution of the patent litigation in favor of the follow-on application or for a specified period of time, whichever is shorter. This reform will require implementing regulations. To date, the NMPA has not issued the relevant implementing regulations.
Patent Term Extension
In early 2019, pursuant to the comprehensive evaluation opinion providedInnovation 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. It is not clear when this will be finalized.
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 CDEState 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 CFDA. We have obtained approvalState Council about the Pilot Urban Resident Basic Medical Insurance , under which urban residents of our Clinical Trial Applicationsthe 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 BGB-283, BGB-3111, BGB-290full or partial reimbursement of the cost of medicines included in the National Reimbursement Drug List, or NRDL. A pharmaceutical product listed in the NRDL must be clinically needed, safe, effective, reasonably priced, easy to use, and BGB-A317available 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 whether 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 trials have been initiated. We must obtain approval of a NDA before ourvalue and drugs can be manufactured and sold infor serious diseases. In addition, the PRC market.

Good Manufacturing Practice

        All facilitiesMinistry of Human Resources and techniques usedSocial 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 the manufactureNRDL. The version of products for clinical use or for salethe NRDL released in 2017 covers 2,535 drugs in total, including 339 new additions, with an emphasis on innovative drugs and drugs that treat cancer and other serious diseases. China has been pursuing a policy of expediting the PRC must be operated in conformity with cGMP guidelines as established byaddition of innovative oncology drugs to this list. In 2018, 17 more oncology drugs were added into 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 promulgatedNRDL by the State ScienceMedical Insurance Bureau.

Government price controls
The Chinese government has abolished the 15-year-old government-led pricing system for drugs, and Technology Commission in November 1988lifted the maximum retail price for most drugs, including drugs reimbursed by government medical insurance funds, patented drugs, and Administrative Measuressome 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 owned by state-owned or controlled enterprises are required to purchase pharmaceutical products through centralized online procurement processes. There are exceptions for drugs on the CertificateNational List of Essential Drugs, which must comply with their own procurement rules, and for Animal Experimentation promulgated by the State Science and Technology Commission and other regulatory authorities in January 2001, performing experimentation on animals requires a Certificate for Use of Laboratory Animals. Applicants must satisfy the following conditions:

        We obtained a Certificate for Use of Laboratory Animals in 2012 regarding the scope of rats and mice.


Regulations Relating to Intellectual Property Rights

Patent

General

        Pursuantcertain drugs subject to the Patent Lawcentral 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 committee randomly selected from a database of experts. The committee members assess the PRC and its implementation rules, patents in the PRC fall 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 respect of the shape, structure or a combination of both of a product; and design patent refers to the new design of a certain product in shape, pattern or a combination of both and in color, shape and pattern combinations aesthetically suitable for industrial application. Under 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.
Other PRC national- and provincial-level 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 any publicationour 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 Regulation of Foreign Investment
Investment activities in China by foreign investors are principally governed by the Guidance Catalogue of Industries for Foreign Investment, or abroad or has been publicly used or made knownthe Catalogue, which was promulgated and is amended from time to time by the MOFCOM and the National Development and Reform Commission. Pursuant to the public by any other means, whetherlatest Catalogue which came into effect in July 2017 with the latest amendment being effective as of July 2018, or the 2017 Catalogue, industries are divided into two categories: encouraged industries and the industries within the catalogue of special management measures, or the Negative List. The Negative List is further divided into two sub-categories: restricted industries and prohibited industries. Establishment of wholly foreign-owned enterprises is generally allowed in industries outside of China, nor has any other person filed with the patent authority an application that describes an identical inventionNegative List. For the restricted industries within the Negative List, some are limited to equity or utility modelcontractual joint ventures, while in some cases Chinese partners are required to hold the majority interests in such joint ventures. In addition, restricted category projects are subject to government approvals and is published after the filing date. Patentscertain special

requirements. Foreign investors are not allowed to invest in industries in the prohibited category. Industries not listed in the Catalogue are generally open to foreign investment unless specifically restricted by other 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 applyregulations. Pursuant to the SIPO for a substantive examination within three years from2017 Catalogue, the date the application is filed.

        Article 20manufacture of the Patent Lawinnovative oncology drugs and certain other kinds of the PRC provides that, for an invention or utility model completed in China, any applicant, not just Chinese companies and individuals, before filing a patent application outside of China, must first submit it to the SIPO for a confidential examination. Failure to comply with this requirement will resultpharmaceutical products falls in the denial of any Chinese patentencouraged industries for the subject invention. This added requirement of confidential examination by the SIPO has raised concerns by foreign companies who conduct research and development activities in the PRC or outsource research and development activities to service providers in the PRC. Currently we have three invention patents published by SIPO and one invention patent under the application process.

Patent Enforcement

        Unauthorized use of patents without consent from owners of patents, forgery of the patents belonging to other persons, or engagement in other infringement acts against patent rights, will subject the infringers to tortious liabilities. Serious offences may be subject to criminal penalties.

        When a dispute arises as a result of infringement of the patent owner's patent right, PRC law requires that the parties first attempt to settle the dispute through consultation between them. However, if the dispute cannot be settled through consultation, the patent owner, or an interested party who believes the patent is being infringed, may either file a civil legal suit or file an administrative complaint with the relevant patent administration authority under the SIPO. A PRC court may issue a preliminary injunction upon the patent owner's or an interested party's request before instituting any legal proceedings or during the proceedings. Damages for infringement are calculated as either the loss suffered by the patent holder arising from the infringement or the benefit gained by the infringer from the infringement. If it is difficult to ascertain damages in this manner, damages may be determined by

investment.

using a reasonable multiple of the license fee under a contractual license. As in other jurisdictions, with one notable exception, the patent owner in the PRC has the burden of proving that the patent is being infringed. However, if the owner of a manufacturing process patent alleges infringement of its patent, the alleged infringer has the burden of proving that it has not infringed. To our knowledge, there are no disputes as to our infringement of any third party's patent.

Medical Patent Compulsory License

        According to the Patent Law of the PRC, the SIPO may grant a compulsory license for manufacturing patented drugs and exporting them to countries or regions covered under relevant international treaties to which the People's Republic of China has acceded.

Exemptions for Unlicensed Manufacture, Use and Import of Patented Drugs

        According to the Patent Law of the PRC, any person may manufacture, use or import patented drugs for the purpose of providing information required for administrative examination and approval without authorization granted by the patent owner.

Trade Secrets

        According to the Anti-Unfair Competition Law of the PRC, the term "trade secrets" refers to technical information and business information that is unknown to the public, that has utility and may create business interest or profit for its legal owners or holders, and that is maintained as a secret by its legal owners or holders.

        Under this law, business persons are prohibited from employing the following methods to infringe trade secrets: (1) obtaining the trade secrets from the legal owners or holders by any unfair methods such as stealing, solicitation or coercion; (2) disclosing, using or permitting others to use the trade secrets obtained illegally under item (1) above; or (3) disclosing, using or permitting others to use the trade secrets, in violation of any contractual agreements or any requirements of the legal owners or holders to keep such trade secrets in confidence. If a third party knows or should have known of the above-mentioned illegal conduct but nevertheless obtains, uses or discloses trade secrets of others, the third party may be deemed to have committed a misappropriation of the others' trade secrets. The parties whose trade secrets are being misappropriated may petition for administrative corrections, and regulatory authorities may stop any illegal activities and fine infringing parties in the amount of RMB 10,000—200,000. Alternatively, persons whose trade secrets are being misappropriated may file lawsuits in a PRC court for loss and damages caused by the misappropriation.

        The measures to protect trade secrets include oral or written agreements or other reasonable measures to require the employees of, or persons in business contact with, legal owners or holders to keep trade secrets confidential. Once the legal owners or holders have asked others to keep trade secrets confidential and have adopted reasonable protection measures, the requested persons bear the responsibility for keeping the trade secrets confidential.

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, 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:

        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:

flows.

        Our PRC subsidiaries' distributions to the offshore parent and their carrying out cross-border foreign exchange activities are 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 required 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 enterprises in the PRC are the PRC Company Law, of the PRC, as amended, the Wholly Foreign-owned Enterprise Law and its implementationimplementating regulations, and the EquitySino-foreign Joint Venture Law and its implementationimplementing regulations. Under these laws, rules and regulations,requirements, foreign-invested enterprises 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 owned PRC enterprises 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. 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.


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

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.

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.

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 and Regulatory Approval 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 successfully complete clinical development, obtain regulatory approval and 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 clinical development, and other drugsdrug candidates 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:

successful enrollment in, and completion of, clinical trials, as well as completion of preclinical studiesstudies;
favorable safety and efficacy data from our clinical trials;

trials and other studies;
receipt of regulatory approvals from the FDA, CFDA, EMA and other comparable regulatory authorities for our drug candidates, including our companion diagnostics;

approvals;
establishing commercial manufacturing capabilities, either by building facilities ourselves or making arrangements with third-party manufacturers;

relying on
the performance by contract research organizations, or CROs, or other third parties we may retain of their duties to conductus in a manner that complies with our clinical trials safelyprotocols and efficiently;

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;

protecting our rights in our intellectual property;

ensuring we do not infringe, misappropriate or otherwise violate the patent, trade secret or other intellectual property rights of third parties;

successfully launching commercial sales of our drug candidates, if and when approved;

obtaining favorable reimbursement from third-party payors for drug candidates,drugs, if and when approved;

competition with other drug candidates and drugs;

products;
continued acceptable safety profile for our drug candidates following regulatory approval, ifapproval; and when received; 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.

candidates and commercialization of our drugs.

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 or be unable to obtain approval 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.

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:

protocol.

        In addition, our clinical trials willlikely 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 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 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.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 protocolsprotocol 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 antitumor 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 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:

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.

        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 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 anddo. This could impair our ability to commercialize our drug candidates and may harm our business and results of operations.

Risks Related to Obtaining Regulatory ApprovalExtensive Government Regulation
All material aspects of the research, development, manufacturing and commercialization of pharmaceutical products are heavily regulated.
All jurisdictions in which we 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 and other Asian countries, and the European Union. 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 Our Drug Candidates

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 received a Breakthrough Therapy designation for zanubrutinib for the treatment of adult patients with mantle cell lymphoma (MCL) who have received at least one prior therapy in January 2019, the FDA may later decide that such drug candidate no longer meets the conditions for qualification and may rescind such 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.
The regulatory approval processes of the FDA, CFDA, EMAregulatory authorities in the United States, China, Europe and other comparable regulatory authorities are lengthy, time consuming and inherently unpredictable, and ifunpredictable. 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 U.S. Food and Drug Administration, or FDA, CFDA,the National Medical Products Administration of China, or NMPA (formerly known as the China Food and Drug Administration or China Drug Administration), the European Medicines Agency, or EMA, and other comparable regulatory authorities is unpredictable butand typically takes many years following the commencement of preclinical studies and clinical trials and depends uponon 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 be delayed or fail to receive regulatory approval from the FDA, CFDA, EMA or a comparable regulatory authority for many reasons, including:

failure to begin or complete clinical trials due to disagreements with the design or implementation of our clinical trials;

regulatory authorities;
failure to demonstrate that a drug candidate is safe and effective or that a biologic drug 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;

failure
reporting or data integrity issues related to demonstrate that a drug candidate'sour clinical and other benefits outweigh its safety risks;

trials;
disagreement with our interpretation of data from preclinical studies or clinical trials;

the insufficiency of data collected from clinical trials of our drug candidates to support the submission and filing of a NDA; or BLA; or other submission or to obtain regulatory approval;

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, CFDA,NMPA, EMA or a comparable regulatory authority may require more information, including additional preclinical, chemistry, manufacturing and controls, or 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. 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 ourthat drug candidatescandidate 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.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.

        If

Our development activities also could be harmed or delayed by a shutdown of the U.S. government, including the FDA.
We believe that our drug candidates’ designation in China as Category 1 products should confer certain regulatory advantages on 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 clinical stage 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 data and market 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 generally 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 additionalnew clinical trialsinvestigations 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 other studiesregulation 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. To be implemented, this framework will require adoption of regulations. To date, the NMPA has issued several draft implementing regulations in this regard for public comment but no regulations have been formally issued. 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 respectestablished cGMPs and international best practices, and passing FDA and NMPA inspections, which may result in a longer and costlier current good manufacturing practice inspection and approval process by the FDA or NMPA for our Chinese manufacturing processes and third party contract manufacturers.
To obtain FDA and NMPA approval for our products in the United States and China, respectively, we will need to anyundergo strict pre‑approval inspections of our drug candidates beyond those thatmanufacturing facilities, which we initially contemplated, if we are unable to successfully completehave located in China, or the manufacturing facilities of our clinical trialscontract manufacturers located in China and elsewhere. Historically, some manufacturing facilities in China have had difficulty meeting the FDA’s or other studiesNMPA's standards. When inspecting our or ifour contractors' Chinese manufacturing facilities, the results of these studies are not positiveFDA or are only modestly positive, we may be delayed in obtaining regulatory approval for that drug candidate,NMPA might cite cGMP deficiencies, both minor and significant, which we may not be ablerequired to obtain regulatory approval at alldisclose. Remediating deficiencies can be laborious and costly and consume significant periods of time. Moreover, if the FDA or NMPA 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 or NMPA may note further deficiencies as a result of its reinspection, either related to the previously identified deficiency or otherwise. If we may obtaincannot satisfy the FDA and NMPA as to our compliance with cGMP in a timely basis, FDA or NMPA marketing approval for indications that are not as broad as intended. Our drug development costs will also increase if we experience delaysour products could be seriously delayed, which 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 theturn would delay commercialization of our drug candidates. Companion diagnostics are subject to regulation

Undesirable adverse events caused by the FDA, CFDA, EMAour drugs 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. Anydrug candidates could interrupt, delay or failure by our collaborators to develop or obtain regulatory approval or clearance of the companion diagnostics couldhalt clinical trials, 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 adverse events, or 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, CFDA,NMPA, EMA or other comparable regulatory authority. Resultsauthorities, or could result in limitations or withdrawal following

approvals. If the conduct or results of our trials couldor patient experience following approval reveal a high and unacceptable severity or prevalence of AEs. In such an event,AEs, our


trials could be suspended or terminated and the FDA, CFDA,NMPA, 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. Undesirablerequire us to cease commercialization following approval.

Numerous drug-related AEs caused by BGB-3111 may include, but are not limitedand serious AEs, or SAEs, have been reported in our clinical trials. Some of these events have led 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.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 potential product liability claims. Any of these occurrences may harm our reputation, business, financial condition and prospects significantly.

        Additionally if one or more of 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, receives regulatory approval,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, or others later identifyIRAEs, have been associated with treatment with checkpoint inhibitors such as our investigational PD-1 inhibitor 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 suchour drugs a number ofand 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 result, including:

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;

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 develop a Risk Evaluation Mitigation Strategy, or 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 comparable 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; and

our reputation may suffer.

patients.

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

        Further, combination therapy, such as using our wholly-owned

Our drugs and any future approved 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

Our drugs and any additional drug candidates that 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.

authorities in China and other countries.

Manufacturers and manufacturers'manufacturers’ facilities are required to comply with extensive FDA, CFDA,NMPA, 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 are and will be subject to continual review and inspections to assess compliance with cGMP and adherence to commitments made in any New Drug Application, or NDA, or Biologics License Application, 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.

        Any

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 including Phase 4 clinical trials 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 which could entail requirements for long-term patient follow-up, a medication guide, physician communication plans or additional elements to ensure safe use, suchfollowing approval, as restricted distribution methods, patient registries and other risk minimization tools.is the case with REVLIMID®. In addition, if the FDA, CFDA,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 cGMP and Good Clinical Practice, or 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 and standards 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 including AEs of unanticipated severity or frequency, or with our third-party manufacturers ordrug’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

The FDA, NMPA, EMA and other regulatory authorities strictly regulatesregulate 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, CFDA,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, CFDA,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.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 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 additionalmay also require post-marketing safety studies. Other comparable regulatory authorities outside the United States, such as the CFDANMPA 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

If safety, efficacy, or other issues arise with any medical product that is used in combination with our drugs, we may be unable to Commercializationmarket 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

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 are not able to obtain, or experience delaysuse in obtaining, required regulatory approvals,combination with our drug candidates, 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 orexperience significant 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 any of our 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 drug candidates, such as BGB-A317, BGB-3111, BGB-290 and BGB-283. In addition, physicians, patients and third-party payors may prefer other novel products to ours. If our drug candidates do not achieve an adequate level of acceptance, we may not generate significant product sales revenuesdelays, and we may not become profitable. The degreebe required to redesign or terminate the applicable clinical trials. In addition, if manufacturing or other issues result in a supply shortage of market acceptanceany component of our drug candidates, if approved for commercial sale, will depend on a number of factors, including:


        If our drug candidates are approved but fail to achieve market acceptance among physicians, patients, hospitals, 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 no experience in marketing drugs. If we are unable to establish marketing and sales capabilities or enter into agreements with third parties to market and sell ourcombination drug candidates, we may not be able to generate product sales revenue.

        We currently have no sales, marketing or commercial product distribution capabilities and have no experience in marketing drugs. We intend to develop an in-house marketing organization and sales force, which will require significant capital expenditures, management resources and time. 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 or decide not to establish internal sales, marketing and commercial distribution capabilities for any or all 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. We may 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 candidates ourselves. We also face competition in our search for third parties to assist us with the sales and marketing efforts of our drug candidates.

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

        Thecomplete clinical 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 developing our drug candidates. Some of these competitive drugs 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. 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 may develop. Our competitors also may obtain approval from the FDA, CFDA, 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 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 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 line therapy, but there is no guarantee thaton our drug candidates, even if approved, would be approved for second linecurrent timeline or first line therapy. In addition,at all, or we may have to conduct additional clinical trials prior to gaining approval for second line or first line therapy.

        Our projectionsexperience disruptions in the commercialization 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 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 andapproved drugs.


Reimbursement may prove tonot be incorrect. 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 populationavailable for our drug candidates may be limited or may not be amenable to treatment with our drug candidates. Even if we


obtain significant market share for our 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 first or second 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 we are able to commercialize our drugs and any approved drug candidates, the drugs may become subject to unfavorable pricing regulations third partyor 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 products vary widely from country to country. 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 the revenues we are able to generate from the sale of the drug in that country. Adverse pricing limitations may hinder our ability to recoup our investment in one or more drug candidates, even if 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.

revenues.

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.
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. 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 genetically modified 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.
In China, the Ministry of Human Resources and Social Security of China 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, or 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. Products included in the NRDL have been typically generic and essential drugs. Innovative drugs similar to our 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.
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.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 candidate that we in-license or successfully develop.

There may be significant delays in obtaining reimbursement for approved product 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. 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


our drugs and any new drugs that we develop could have a material adverse effect on our business, our operating results, our ability to raise capital needed to commercialize drugs and our overall financial condition.

Coverage and reimbursement may be limited or unavailable in certain market segments for our drug candidates, which could make it difficult for us to sell our drug candidates profitably.

        Successful sales of our 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 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. Even if we obtain coverage for a given drug, the resulting reimbursement payment 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 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 authoritiescontrol, which can take considerable time even after obtaining regulatory approval of a drug candidate. In addition, marketapproval. Market acceptance and sales of our drug candidatesdrugs will depend significantly on the availability of adequate coverage and reimbursement from third-party payors for our drug candidatesdrugs 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 drug candidates and affect the prices we may obtain.

In the United States, PRC,China, the 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 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.

        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.


        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. Congressrecent 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 FDA's approval process may significantly delayAffordable Care Act, or prevent regulatory approval, as well as subject us to more stringent product labeling and post-marketing testing and other requirements.

        As a resultACA. The implications of the 2016 electionACA, 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 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.
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 fatesatisfaction of the ACAFDA, 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 NDA or BLA must include significant information regarding the chemistry, manufacturing and controls 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 any submissions will be accepted for filing and review by the FDA.
We have not yet demonstrated an ability to receive regulatory approval for our drug candidates. For example, we have limited experience in preparing the required materials for regulatory submission and do not have experience 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 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 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.
The process to develop, obtain regulatory approval for and commercialize drug candidates is long, complex and costly both inside and outside the United States and China, 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 manufacturing processes and additional labeling claims, may be subject to additional review and approval by the FDA, NMPA and EMA and comparable regulatory authorities. Also, regulatory approval for any of our drug candidates may be withdrawn. If we are unable to obtain regulatory approval for our drug candidates in one or more jurisdictions, 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 will be harmed. Furthermore, we may not be able to obtain sufficient funding or generate sufficient revenue and cash flows to continue the development of any other drug candidate in the future.
We have limited manufacturing capability and must rely on third-party manufacturers to manufacture our clinical supplies and commercial products, if and when approved, and if they fail to meet their obligations, the development and commercialization of our products could be adversely affected.
We have limited manufacturing capabilities and experience. Our drug candidates are composed of multiple components and require specialized formulations for which scale-up and manufacturing could be difficult. We have limited experience in such scale-up and manufacturing requiring us to depend on a limited number of third parties, who may not be able to deliver in a timely manner, or at all. In order to develop products, apply for regulatory approvals, and commercialize our products, we will need to develop, contract for, or otherwise arrange for the necessary manufacturing capabilities. There are risks inherent in pharmaceutical manufacturing that could affect the ability of our contract manufacturers to meet our delivery time requirements or provide adequate amounts of material to meet our needs.
Additionally, our internally-developed drug candidates have not yet been manufactured for commercial use. If any of our drug candidates become approved for commercial sale, we will need to establish either internal or third-party manufacturing capacity. Manufacturing partner requirements may require us to fund 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, we will have to successfully transfer manufacturing technology to a different manufacturer. Engaging a new manufacturer for such an approved drug could require us to conduct comparative studies or utilize other means to determine bioequivalence of the new and prior 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 development and commercialization of such an approved drug may be delayed or there may be a shortage in supply. Any inability to manufacture our drug candidates or future approved drugs in sufficient quantities when needed would seriously harm our business.
Manufacturers of our approved drugs, if any, must comply with cGMP requirements enforced by the FDA, NMPA and other healthcarecomparable 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, if any, may be unable to comply with these cGMP requirements and with other FDA, NMPA, 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 manufacturer’s failure to adhere to applicable laws or for other reasons, we may not be able to obtain regulatory approval for or successfully commercialize our products, which would seriously harm our business.
Our drugs and any future approved drug candidates 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.
Our drugs and any future approved drug candidates may 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. In addition, physicians, patients and third-party payors may prefer other novel products to ours. If our drugs and drug candidates do not achieve an adequate level of acceptance, we may not generate

significant product 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;
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 regulatory authorities;
limitations or warnings contained in the labeling approved by 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;
the availability of adequate coverage, reimbursement and pricing by third-party payors and government authorities;
the willingness of patients to pay out-of-pocket in the absence of coverage and reimbursement by third-party payors and government authorities; and
the effectiveness of our sales and marketing efforts.
If any drugs that we commercialize fail to achieve market acceptance among physicians, patients, hospitals, 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 have limited experience in marketing third-party drugs and no experience in launching an internally-developed drug candidate. If we are unable to further develop marketing and sales capabilities or enter into agreements with third parties to market and sell our drug candidates and third-party drugs, we may not be able to generate product sales revenue.
In connection with our strategic collaboration with Celgene, we were granted an exclusive license in China, excluding Hong Kong, Macau and Taiwan, to commercialize Celgene’s approved cancer therapies, ABRAXANE®, REVLIMID®, and VIDAZA®, and Celgene’s investigational agent avadomide (CC-122) in clinical development, and acquired Celgene’s commercial operations in China, excluding certain functions. We started marketing Celgene’s approved drugs in September 2017. We continue to build our salesforce in China to market these drugs and our drug candidates, in the event they receive commercial approval, and any additional drugs or drug candidates that we may in-license, which will require significant capital expenditures, management resources and time.
We have not yet demonstrated an ability to launch and commercialize any of our drug candidates. For example, we do not have experience in building a commercial team, conducting a comprehensive market analysis, obtaining state licenses and reimbursement, or managing distributors and a sales force for our internally-developed drug candidates. As a result, our ability to successfully commercialize our drug candidates may involve more inherent risk, take longer, and cost more than it would if we were a company with experience launching drug candidates.
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, further develop internal sales, marketing and commercial distribution capabilities for any or all of our drugs, 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. We would 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 drugs ourselves. We also face competition in our search for third parties to assist us with the sales and marketing efforts for our drugs.

There can be no assurance that we will be able to further develop and successfully maintain in-house sales and commercial distribution capabilities or establish or maintain relationships with third-party collaborators to successfully commercialize any product, and as a result, we may not be able to generate 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 uncertain. highly competitive. We face competition 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. 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.
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, NMPA, 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.
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.
The United States House of Representatives is consideringmarket 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.
In markets with approved therapies, we expect to initially seek approval of legislationour drug candidates as a later stage therapy for patients who have failed other approved treatments. Subsequently, for those drugs that prove to repeal partsbe sufficiently beneficial, if any, we would expect to seek approval as a second line therapy and potentially as a first line therapy, but there is no guarantee that our drug candidates, even if approved, would be approved for second line or first line therapy.
Our projections of both the ACA, but it is uncertain whether Congress will replacenumber of people who have the lawcancers we are targeting, as well as the subset of people with these cancers in a position to receive later stage therapy and what any replacement law would provide.

who have the potential to benefit from treatment with our drug candidates, are based on our beliefs and estimates and may prove to be 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 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 first or second line therapy.

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, our operations may be 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 be 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, not just governmental payors, including private insurers. In addition, 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 the Pharmaceutical Research and Manufacturersother voluntary industry codes of America's Code on Interactions with Healthcare Professionals.conduct. Several states also impose other marketing restrictions or require pharmaceutical companies to make marketing or price disclosures to the state. 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, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could adversely affect our ability to operate our business and our results of operations. In addition, the approval and commercialization of any of our drug candidates outside the United States will also likely subject us to non-U.S. equivalents of the healthcare laws mentioned above, among other non-U.S. laws.

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 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 the Celgene transactions, we retained exclusive rights for the development and commercialization of tislelizumab for hematological cancers globally and for solid tumors in China and the rest of Asia, other than Japan. We initially intend to focus on opportunities in China, in particular. If we fail to obtain licenses or enter into collaboration 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, 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 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 drugs. We have not yet completed large-scale, pivotal or registrational clinical trials, obtained regulatory approvals, or manufactured or had manufactured a commercial scale drug. We have no internally-developed products approved for commercial sale and have not generated any revenue from internally-developed product sales. Since September 2017, we have generated revenues from the sale of drugs in China licensed from Celgene. 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 Celgene. As of December 31, 2018 and 2017, we had an accumulated deficit of $1.0 billion and $330.5 million, 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, and continue to commercialize the drugs that we have licensed from Celgene 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 any 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 and development efforts, expand our business or continue our 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.
Our 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 $547.7 million and provided $12.8 million of net cash during the years ended December 31, 2018 and 2017, respectively. We recorded negative net cash flows from operating activities in 2018 primarily due to our net loss of $674.0 million. Although we recorded positive net cash flows from operating activities in 2017, primarily due to the upfront fees received from the Celgene collaboration, we cannot assure you that we will be able to generate positive cash flows from operating activities in the future. 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 finance 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, developing our manufacturing capabilities and securing drug supply, commercializing our drugs and launching and commercializing any drug candidates for which we receive regulatory approval, including building our own commercial organization to address markets in China, the United States and other markets.
While we have generated product revenue in China since September 2017 from sales of our drugs licensed from Celgene, 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 will not be sufficient to enable us to complete all global development or commercially launch all of our current drug candidates for the currently anticipated indications and to invest in additional programs. Accordingly, we will 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:
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 drug candidates that we may in-license and develop;
the amount and timing of the 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 in China 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 People’s Republic of China, or 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 and RMB, 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'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 $712.9 million and $239.6 million, restricted cash of $27.8 million and nil and short-term investments of $1.1 billion and $597.9 million at December 31, 2018 and 2017, 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, 2018 and December 31, 2017, our short-term investments consisted primarily of U.S. Treasury securities, U.S. agency securities and time deposits. Although we believe that the U.S. Treasury securities, U.S. agency securities and time deposits are of high credit quality and continually monitor the credit worthiness of these institutions, concerns about, or a default by, one institution in the U.S. 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 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 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. UnderNational Intellectual Property Administration, or NIPA, for security examination. Otherwise, if an application is later filed in China, the Leahy-Smith America Invents Act enactedpatent right will not be granted.

The coverage claimed in 2011,a patent application can be significantly reduced before the patent is issued, and its scope can be reinterpreted after issuance. Even if patent applications we license or own currently or in the future 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. In 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 patent rights are highly uncertain.
The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our patents may be challenged in the courts or patent offices in the United States, movedPRC and other countries. We may be subject to this first-to-file system in early 2013 from the previous system under which the first to make the claimed invention was entitleda third-party preissuance submission of prior art to the patent. We mayUSPTO or become involved in interferenceopposition, derivation, revocation, re-examination, post-grant and inter partes partes review, post grant review,ex parte reexamination, derivation, oppositionor interference proceedings or similar other 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 drug candidates and compete directly with us without payment to us, or result in our inability to manufacture or commercialize drug candidates without infringing, misappropriating or otherwise violating third-party patent rights.

        There can be no assurance that our pending patent applications will result Moreover, we may have to participate in issued patentsinterference proceedings declared by the USPTO to determine priority of invention or in the United States or non-U.S. jurisdictions in whichpost-grant challenge proceedings, 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 applications issue as patents, they may not issueoppositions in a formforeign patent office, that will provide us with any meaningful protection, prevent competitors from competing with uschallenge the priority of our invention or otherwise provide us with any competitive advantage. Our competitors may be able to circumventother features of patentability of our patents by developing similar or alternative technologies or drug candidates in a


non-infringing manner. The issuance of aand patent is not conclusive as to its scope, validity or enforceability, and our owned and licensed patents may be challenged in the courts or patent offices in the United States and abroad.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 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 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 Celgene 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 drug candidates even if we successfully obtain patent protection once the patent life has expired for the drug or if the patents are not enforced. 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 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, 2018. 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 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.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 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 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 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 drug candidates.

Our commercial success depends in part on our avoiding infringement of the 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 in which we are developing our 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 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 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 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 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 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. Thiszanubrutinib 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 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 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 candidate before the expiration of a corresponding patentpatents covering BGB-3111. Howeverthat 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 ourdata exclusivity for any 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 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 ActAction of 1984, referred to as the Hatch-Waxmanor Hatch Waxman Amendments. The Hatch-WaxmanHatch 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 beyond the new pilot program, and implementation of the pilot program 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 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 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

We rely on third parties to conduct our preclinical studies and clinical trials.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 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, and 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, CFDA,NMPA, EMA and other comparable regulatory authorities for all of our drugs in clinical development. Regulatory authorities enforce these GCPs through periodic inspections of trial sponsors, principal investigators and trial sites. 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, CFDA,NMPA, 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 pivotal 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 We could also be subject to terminate their agreements 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, if we make a general assignment for the benefit of our creditors or if we are liquidated.

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 nonclinical and preclinicalnonclinical 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 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 influence our ability to meet our desired clinical development timelines. Though we carefully manage our relationships with our CROs, thereThere 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 our ability to work effectively with collaborators to develop our 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 expect to rely on third parties to manufacture at least a portion of our clinical and commercial 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 facility that may be used as our clinical-scale manufacturing and processing facility and are building manufacturing facilities in China, we intend to at least partially rely on outside vendors to manufacture supplies and process our drugs and drug candidates. WeFor example, we have entered into a commercial supply agreement for tislelizumab with Boehringer Ingelheim Biopharmaceuticals (China) Ltd. In addition, we rely on Celgene and its third-party manufacturers for supply of ABRAXANE®, REVLIMID®, and VIDAZA® in China. Our drug candidates have not yet caused our drug candidates to bebeen manufactured or processed on a commercial scale and we may not be able to do so for any of our drug candidates. 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 drug candidates. This approvalevaluation would require new testing and cGMP-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 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 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 manufacturers may not be able to execute our manufacturing procedures and other logistical support requirements appropriately;

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 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.

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 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. 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. 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 have entered into collaborations, such as with Celgene, 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 drug candidates and any future 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.
Our strategic collaboration with Celgene involves numerous risks. There can be no assurance that we will be able to successfully manage and integrate Celgene’s commercial operations in China and its personnel into our business, which could disrupt our business and harm our financial results. Moreover, we may not achieve the revenue and cost synergies expected from our collaboration with Celgene for their commercial products in China and the joint development of tislelizumab outside of Asia (other than Japan), 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. Also, the synergies from our collaboration with Celgene may be offset by costs incurred in integrating Celgene’s commercial operations in China, increases in other expenses, operating losses or problems in the business unrelated to our collaboration with Celgene. As a result, there can be no assurance that these synergies will be achieved. Lastly, strategic collaborations can be terminated for various reasons. For example, in 2013, we entered into


collaboration agreements with Merck KGaA, Darmstadt Germany pursuantJanuary 2019, Celgene announced that it was expected to which we have agreed to license the ex-China rights of BGB-283 to Merck KGaA, Darmstadt Germany as discussed furtherbe acquired by Bristol-Myers Squibb Company in the section titled "Item 1—Business—Collaborationthird quarter of 2019. As a result of this transaction, our licensing agreement with Merck KGaA, Darmstadt Germany" in this Annual Report. In addition, weCelgene for tislelizumab may be terminated.

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 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 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 candidate, we can expect to relinquish some or all of the control over the future success of that 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 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 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 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 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 drug candidates or bring them to market and generate product sales revenue, which would harm our business prospects, financial condition and results of operations.

If we fail to maintain an effective distribution channel for our products, our business and sales of the relevant products could be adversely affected.
We rely on a third-party distributor to distribute Celgene’s approved cancer therapies, ABRAXANE®, REVLIMID®, and VIDAZA®, and we expect to rely on third-party distributors for the distribution of our internally developed drug products, if approved. Our ability to maintain and grow our business will depend on our ability to maintain an effective distribution channel that ensures the timely delivery of our products 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 products in the manner we contemplate. While we have long-standing business relationship with our distributor for the in-licensed products from Celgene, the agreement we entered into with our distributor can be terminated by both parties upon six months’ written notice. If PRC price controls or other factors substantially reduce the margins our distributor can obtain through the resale of our products to hospitals, medical institutions and sub-distributors, it may terminate its relationship with us. As of the date of this report, we rely on one distributor to distribute our products. While we believe alternative distributors are readily available in China, there is a risk that, if the distribution of our drugs is interrupted, our sales volumes and business prospects could be adversely affected.

We may be restricted from transferring our scientific data abroad.
On March 17, 2018, the General Office of the State Council promulgated the Measures for the Management of Scientific Data, or the Scientific Data Measures, which provides a broad definition of scientific data and relevant rules for the management of scientific data. 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 we can always obtain relevant approvals for sending scientific data (such as the results of our preclinical studies or clinical 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.
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 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, 2016,2018, we had 348876 employees, and consultants and mostwe ended the year with 2,070 employees, an increase of approximately 136%. 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 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 Exchange Act.Act and the listing rules of the Stock Exchange of Hong Kong Ltd., or HKEx, and incur significant legal, accounting and other expenses under the Sarbanes-Oxley Act of 2002, or 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 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 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 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.
PRC regulations and rules concerning mergers and acquisitions, including the Regulations on Mergers and Acquisitions of Domestic Companies by Foreign Investors, or 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, or 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 PRC and the Provisions on Thresholds for Prior Notification of Concentrations of Undertakings, or 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, or 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, or 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. 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 the SAMR, the MOFCOM or its local counterparts may delay or inhibit our ability to growcomplete such transactions. It is unclear whether those complementary business 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, the 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 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.

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 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. 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 the PRC anti-corruption and other 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 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.
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, 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, or 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. 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 computer systems, or those used by our CROs or other contractors or consultants, may fail or suffer security breaches.

Despite the implementation of security measures, our internal computer systems and those of our future CROs and other contractors and consultants are vulnerable to damage from computer viruses and unauthorized access. 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, 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 have an adverse impact on us and our business, including loss of data and damage to equipment and 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.
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 strict 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 relating to identifiable individuals and transferring such information outside the European Economic Area (including to the United States), providing details to those individuals regarding the processing of their personal information, keeping personal information secure, having data processing agreements with third parties who process personal information, 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 substantially increases the penalties to which we could be subject in the event of any non-compliance, including fines of up to 10,000,000 Euros or up to 2% of our total worldwide annual turnover for certain comparatively minor offenses, or up to 20,000,000 Euros or up to 4% of our total

worldwide annual turnover for more serious offenses. 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 courts in interpretation of the new law. 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.
Regulatory authorities in China have implemented and are considering a number of legislative and regulatory proposals concerning data protection. For example, China’s 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 transfers published by the China Cyberspace Administration in 2017, 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. The Interim Measures for the Administration of Human Genetic Resources and implementation guidelines issued by the Ministry of Science and Technology, for example, require approval from the Ministry of Science and Technology before the commencement of clinical trials where foreign sponsors and their Chinese clinical trial sites obtain human genetic resources, or HGR, in China and additional approval for any export or cross-border transfer of the HGR samples or associated data. See “Part I-Item 1-Business-Government Regulation-PRC Regulation-Human Genetic Resources Approval”. It is possible that these laws may be interpreted and applied in a manner that is inconsistent with our practices, potentially resulting in confiscation of HGR samples and associated data from completedand administrative fines. In addition, the interpretation and application of data protection laws in China and elsewhere are often uncertain and in flux.
We expect that we will continue to face uncertainty as to whether our efforts to comply with evolving obligations under global data protection, privacy and security laws will be sufficient. Any failure or future clinical trialsperceived failure by us to comply with applicable laws and regulations could result in delaysreputational 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 regulatory approval efforts and significantlybusiness 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.

If we or parties on whom we rely fail to maintain the extent that any disruptionnecessary 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 security breach were toaudits 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.

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, 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 or 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 government shutdowns or withdrawn funding. The occurrence of any of these business disruptions 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 disaster or other business interruption. A large portion of our operations is located in a single facility in Changping, Beijing, PRC. Damage or extended periods of interruption to our corporate, development, research or researchmanufacturing facilities due to fire, natural disaster, power loss, communications failure, unauthorized entry or other events could cause us to cease or delay development or commercialization of some or all of our 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

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 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 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 recovery from the lows of 2008 and 2009 was uneven 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 crisis will be contained 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 that have been adopted by the central banks and 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 produces 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 spaceSuzhou, China and are building a biologics 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 projectGuangzhou, China. These facilities may encounter unanticipated delays and cost more than expectedexpenses due to a number of factors, including regulatory requirements. If construction, regulatory evaluation and/or regulatory approval of our new facility isfacilities are delayed, we may not be able to manufacture sufficient quantities of our drug candidates and our drugs, if approved, 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 new drug approvals and ongoing, periodic inspection by the FDA, CFDA,NMPA, EMA or other comparable regulatory agencies to ensure compliance with cGMP.cGMP and other regulatory requirements. Our failure to follow and document our adherence to such cGMP 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 drugs.drug candidates or the commercialization of our drugs, if approved. 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 cGMP 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 produce our drugs in the quantities that we believe will be required to meet anticipated market demand of any of our drug candidates if approved, we will need to increase, or "scale“scale up," the production process by a significant factor over the initial level of production. 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 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.
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.
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 operations and manufacturing facilities are

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. 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.

The MOFCOM published a discussion draft of the proposed Foreign Investment Law, or the 2015 Draft Foreign Investment Law, in January 2015 and completed the solicitation of comments on this draft in February 2015. In December 2018, the PRC National People’s Congress Standing Committee reviewed and published a revised draft Foreign Investment Law, or the 2018 Draft Foreign Investment Law, which was further revised by the Standing Committee of the National People’s Congress in its second review meeting held on January 29, 2019. The 2018 Draft Foreign Investment Law will replace the major existing laws and regulations governing foreign investment in China upon its enactment. There are substantial uncertainties with respect to the enactment timetable and the final content of the Foreign Investment Law and its implementation rules. The 2018 Draft Foreign Investment Law requires foreign investors or applicable foreign invested entities, or FIEs, to report investment information to government authorities. Although the 2018 Draft Foreign Investment Law does not specify the form, content, scope and frequency of such information reporting, it provides monetary fines of up to RMB 500,000 on non-compliance of such information reporting obligations. The PRC governmental authorities may promulgate implementation rules after the Foreign Investment Law is enacted and further clarify the detailed information reporting requirements on foreign investors and the applicable FIEs. In that case, our current corporate governance practices and business operations may be materially affected 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 future PRC-residentthe PRC plan participants and PRC-residents 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 State Administration of Foreign Exchange, or 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, or SAFE Circular 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, 2016,2018 and December 31, 2017, these restricted assets totaled RMB69.1$93.3 million ($10.0 million).

and $29.9 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, or 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, 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 "HongHong Kong Tax 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, 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, 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 State Administration of Taxation, or the SAT, issued Administrative Measures 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 providehas 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, 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,or 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.

Recent litigation

Our business benefits from certain financial incentives and negative publicity surrounding China-based companies listeddiscretionary policies granted by local governments. Expiration of, or changes to, these incentives or policies would have an adverse effect on our results of operations.
Local governments in the United States may result in increased regulatory scrutinyPRC have granted certain financial incentives from time to time to our PRC subsidiaries as part of ustheir efforts to encourage the development of local businesses. 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. We cannot assure you of the continued availability of the government incentives currently enjoyed by us. Any reduction or elimination of incentives would have an adverse effect uponon our business, including its results of operations, financial condition, cash flowsoperations.

resources and energy, potential costs to defend ourselves against rumors, decreases and volatility in the ADS trading price, and increased directors and officers insurance premiums and could have a material adverse effect upon our business, including its results of operations, financial condition, cash flows and prospects.

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, 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.

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, or 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.

States, and the market price of the ordinary shares may be adversely affected.

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 Chinathe PRC 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 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. Because of the different characteristics of the U.S. and Hong Kong equity markets, the historic market prices of our ADSs may not be indicative of the performance of our securities (including the ordinary shares) 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. 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

Our ordinary share and/or ADS price 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 15, 2019, 776,113,184 ordinary shares, par value $0.0001 per share, were outstanding, of which 251,251,247599,894,893 ordinary shares were held in the form of 19,327,01946,145,761 American Depositary Shares.

Shares, each representing 13 ordinary shares.

We filed a registration statement with the SEC on behalf of certain shareholders, 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. 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 Celgene in the public market.

event that they are not eligible for sale under Rule 144.

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, 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 Islands or in China 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 in China or their assets are located in 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 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 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 potentially 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.

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, 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.


You

Holders 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, or 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%52.6% of our outstanding ordinary shares as of March 17, 2017.February 15, 2019. 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,” (or a “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

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.

Shareholders

As of March 17, 2017,January 31, 2019, we had approximately 101166 holders of record of our ordinary shares and one holder7 holders of record of the ADSs. This number does not include beneficial owners whose ordinary shares or ADSs are held by nominees in street name. Because many ordinary shares held in the form ofand ADSs are held by broker nominees, we are unable to estimate the total number of beneficial holders represented by these record holders.

Dividend Policy

We have never declared or paid any dividends on our ordinary shares or any other securities. We currently intend to retain all available funds and any future earnings, if any, to fund the development and expansion of our business and we do not anticipate paying any cash dividends in the foreseeable future. Investors should not purchase theour ordinary shares or ADSs with the expectation of receiving cash dividends.

        Any future determination to pay dividends will be made at the discretion of our board of directors and may be based on a number of factors, including our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that our board of directors may deem relevant. If we pay any dividends, we will pay the ADS holders to the same extent as holders of our ordinary shares, subject to the terms of the deposit agreement, as amended, including the fees and expenses payable thereunder. Cash dividends on our ordinary shares, if any, will be paid in U.S. dollar.


        If we pay dividends in the future, in order for us to distribute dividends to our shareholders and ADS holders, we will rely to some extent on any dividends distributed by our PRC subsidiaries. Any dividend distributions from our PRC subsidiaries to us will be subject to PRC withholding tax. In addition, regulations in the PRC currently permit payment of dividends of a PRC company only out of accumulated distributable after-tax profits as determined in accordance with its articles of association and the accounting standards and regulations in China. See the section of this Annual Report titled "Part I—Item 1A—Risk Factors—Risks Related to Our Doing Business in the PRC—In the future, we may rely to some extent on dividends and other distributions on equity from our principal operating subsidiaries to fund offshore cash and financing requirements."

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.

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.

People's

People’s Republic of China 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.

Overview

We are a globallycommercial-stage biotechnology company focused clinical-stage biopharmaceutical company dedicated to becoming a leader in the discoveryon developing and development ofcommercializing innovative molecularly targetedmolecularly-targeted and immuno-oncology drugs for 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, we have developed a proprietary cancer biology platform that addresses 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 ofinternally-developed lead drug candidates with the potential to beare currently in late-stage clinical trials. These candidates are (1) zanubrutinib (BGB-3111), a potentially 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-3111 is a potent and highly selectiveinvestigational small molecule inhibitor of BTK. BGB-290 is a molecularly targeted, orally available, potent and highly selective inhibitor of PARP1 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 responses in the defined patient populations. BGB-3111 received orphan drug designation from the FDA, for CLL, MCL and WM. Our clinical-stage immuno-oncology agent, BGB-A317, isBruton’s tyrosine kinase, or BTK, (2) tislelizumab (BGB-A317), an investigational humanized monoclonal antibody against the immune checkpoint receptor PD-1. We have IND Applications in effect for our BTK, PD-1programmed cell death protein 1 (PD-1), and PARP inhibitors with(3) pamiparib (BGB-290), an investigational small molecule inhibitor of the FDA. We have also received approvalpoly ADP-ribose polymearase 1 (PARP1) and PARP2 enzymes. All three of our Clinical Trial Applications for each of our four clinical-stagethese drug candidates from the CFDA. In addition to our clinical-stageare currently in Phase 2 or 3 pivotal trials globally and/or in China, and we filed for regulatory approvals in China in 2018 for zanubrutinib in relapsed/refractory (R/R) mantle cell lymphoma (MCL) and in R/R chronic lymphocytic leukemia or R/R small lymphocytic lymphoma (CLL/SLL); and for tislelizumab in R/R classical Hodgkin's Lymphoma (cHL). We also have additional drug candidates we havein earlier stage clinical development.

We started as a robust pipeline of preclinical programs and are planning to advance one or more of these programs into the clinic in the next 12 months. 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 any revenue from product sales. We have financed operations through a combination of public and private equity and debt financings and public and private grants and contracts, including the net proceeds from our initial public offering and follow-on public offering, the net proceeds from the issuance of a senior note and convertible promissory note to Merck Sharp & Dohme Research GmbH, or MSD, an affiliate of Merck Sharp & Dohme Corp., the private placements of our Series A preferred shares and Series A-2 preferred shares, and our collaboration 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 for the years ended December 31, 2016, 2015 and 2014, respectively. As of December 31, 2016, we had an accumulated deficit of $237.4 million. In the future, we may generate revenue from product sales, collaboration agreements, strategic alliances and licensing arrangements, or a combination of these. Substantially all of our losses have resulted from funding our research and development programscompany in Beijing in 2010, focusing on developing best-in-class oncology drugs. Over the last nine years, we have developed into a fully-integrated global biotechnology company with operations in China, the United States, Europe and general and administrative costs associated with our operations. We expect to continue to incur significant expenses and operating losses for 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 andAustralia, including a more than 800-person global clinical development team running 50 ongoing or planned clinical trials as of January 24, 2019. We also have a growing commercial team that is selling our existing in-licensed drugs in China and preparing for launches 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 ourinternally-developed drug candidates in China and the United States, as well as internal manufacturing capabilities in China that are operational or under construction for the clinical and commercial supply of our small molecule and biologic drug candidates.

Recent Developments
On January 14, 2019, we announced that the U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy designation for our investigational Bruton's tyrosine kinase (BTK) inhibitor, zanubrutinib, for the treatment of adult patients with mantle cell lymphoma (MCL) who have received at least one prior therapy.
On December 17, 2018, we announced the initiation of two global Phase 3 clinical trials of our investigational anti-PD-1 antibody, tislelizumab. These trials are evaluating tislelizumab combined with chemotherapy as potential first-line treatments in patients with locally advanced unresectable or metastatic gastric or gastroesophageal junction adenocarcinoma, and in patients with unresectable, locally advanced recurrent or metastatic esophageal squamous cell carcinoma (ESCC).
On November 27, 2018, we entered into a timely manner or obtain regulatory approval of them, our abilitylicense and collaboration agreement with Zymeworks, Inc. (NYSE/TSX: ZYME) in which we acquired exclusive development and commercial rights to generate future revenue,Zymeworks' bispecific candidates, ZW25 and our results of operationsZW49, in Asia (excluding Japan), Australia and financial position, would be materially adversely affected.

        Cash used in operations were $89.5 million, $39.8New Zealand. We also acquired licenses for Zymeworks' AzymetricTM and EFECTTM platforms to develop and commercialize up to three bispecific antibody therapeutics globally directed to BeiGene's targets. Zymeworks received upfront payments totaling $60.0 million and $8.7 million, respectively,is eligible to receive development and commercial milestone payments plus potential royalties on product sales.

On November 13, 2018, we announced the Center for years ended December 31, 2016, 2015Drug Evaluation of China's National Medical Product Administration (NMPA, formerly known as CFDA) granted priority review status to the New Drug Applications for zanubrutinib in patients with R/R MCL and 2014.

Financial Operations Overview

Operating Results

Revenue

To date, our revenue has consisted of product sales revenue since September 2017 and upfront license fees and reimbursed research and development expenses from our strategic collaboration with Celgene for tislelizumab entered in 2017 and upfront license fees and milestone payments from our collaboration agreements with Merck KGaA, Darmstadt Germany on BGB-283for pamiparib and BGB-290.lifirafenib entered in 2013. We have not generated any revenue from product sales and do not expect to generate anysignificant revenue from internally-developed drug candidates unless and until we successfully complete development and obtain regulatory approval for one or more of our drug candidates, which is subject to significant uncertainty.
Revenues from product sales are recognized when there is a transfer of control from the Company to the distributor. The Company determines transfer of control based on when the product is delivered, and title passes to the distributor. Revenues from product sales are recognized net of variable consideration resulting from rebate accruals and sales returns allowances. Provisions for estimated reductions to revenue are provided for in the same period the related sales are recorded and are based on the sales terms, historical experience and trend analysis. We expect revenue from product sales to increase in 2019 as we expand our efforts to promote and obtain reimbursement for the foreseeable future.

        On May 24, 2013, we entered into license agreements with Merck KGaA, Darmstadt Germany on BGB-283, which we amendedABRAXANE® and restated on December 10, 2013,REVLIMID® 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 inhibitorlaunch VIDAZA® in The People's Republic of China, which we refer 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 Option in the ex-PRC Territory, and thus, the ex-PRC BRAF Agreement has terminated in its entirety, except 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

China.

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 achievement of a certain additional regulatory event in the PRC Territory. In consideration for the licenses granted 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 inalso record revenue from our collaboration and license agreements with Merck KGaA, Darmstadt Germany, comprised of an aggregate of $22.0 million related to BGB-283Celgene and $12.0 million related to BGB-290. The revenue consists of an upfront non-refundable license fee, Phase 1 research and development fees, 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 years ended December 31, 2016, 2015 and 2014, substantially all of our revenue were generated solely from Merck KGaA, Darmstadt Germany. ForUnder each agreement, we have received upfront payments related to the foreseeable future,license fee which was recognized upon the delivery of the license right. Additionally, the reimbursement of remaining undelivered research and development services under the Celgene arrangement is recognized over the performance period of the collaboration arrangement. In the case of the Celgene arrangement, we expect substantially allwill also receive research and development reimbursement revenue for the basket study trials that Celgene opts into. We consider milestone payments variable consideration and include them in the transaction price when a significant reversal of revenue recognized is not expected to occur. See Note 3 to our consolidated financial statements included in this Annual Report for a description of these agreements.

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:

expenses incurred under agreements with contract research organizations, or CROs, contract manufacturing organizations, and consultants that conduct and support 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:

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; and
BGB-A425, an investigational humanized monoclonal antibody against TIM-3.
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., and
ZW25 and ZW49, two bispecific antibody-based product candidates targeting HER2, under development by Zymeworks Inc.
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-developed drug candidates. We are also unable to predict when, if ever, material net cash inflows will commence from sales of our internally-developed drug candidates. This is due to the numerous risks and uncertainties associated with developing such 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 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 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-290 and BGB-283our drug candidates as a treatmenttreatments for various cancers and as we move these drug candidates into additional clinical trials, including potential pivotal trials. There are numerous factors associated with the successful commercialization of any of our 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 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® (nanoparticle albumin–bound paclitaxel), REVLIMID® (lenalidomide), and VIDAZA® (azaciditine) in China and the preparation for launch and potential commercialization of our internally-developed 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-290 and BGB-283our drug candidates as a treatmenttreatments for various cancers and the initiation of our clinical trials for our otherpotential new 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.

company with our ADS and ordinary shares listed for trading on The NASDAQ Global Select Market and Hong Kong Stock Exchange, respectively.

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 loan 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.

Operating Capital Requirements

We do not expect to generate significant revenue from product sales of our internally developed drug candidates unless and until we obtain regulatory approval offor and commercialize one of our current or future drug candidates. We have exclusive rights to distribute and promote Celgene’s approved cancer therapies in China, for which we began recognizing revenue in the third quarter of 2017. We anticipate that we will continue to generate losses for the foreseeable future, and we expect theour losses to increase as we continue the development of, and seek regulatory approvals for, our drug candidates, and prepare for commercialization and begin to commercialize any 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.manufacturing of our in-licensed drug products in China and, subject to obtaining regulatory approval, our drug candidates. Accordingly, we anticipate that we will 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, 2016,2018, 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. 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; our other ongoing and planned clinical trials; regulatory filing and registration of our late-stage drug candidates; expansion of commercial operations in China and preparation for launch of our 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. Because of the numerous risks and uncertainties associated with the development and commercialization of our 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:

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 drug candidatecandidates we pursue;

the costs of establishing 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 expect 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. 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.

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, the Company 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, 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 distributor subsequently resells the products to second tier distributors who ultimately sell the products to health care providers and patients. The Company is the principal under the product sale 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 its first tier distributer. The Company has a single performance obligation which is to sell the products to its first tier distributer. 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 sales rebates and returns 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 first tier distributer. The Company's payment terms are approximately 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, under different assumptionswhich would affect net product revenue and earnings in the period such variances become known.
Rebates, including price compensation credits, are offered to distributors, consistent with pharmaceutical industry practices. The Company records 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.

        We believereimbursement amounts (such as provincial acceptance of the following critical accounting policies reflect our more significantNational Reimbursement Drug List pricing in the PRC). The Company regularly reviews the information related to these estimates and assumptions usedadjust the provision accordingly.

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. If the historical data the Company uses to calculate these estimates do not properly reflect future returns, then a change in the preparationallowance 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 our financial statements.

Revenue Recognition

        We recognize revenues from researchASC 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 development collaborativeexposed to significant risks and rewards dependent on the commercial success of such activities. For collaboration arrangements when persuasive evidencewithin 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. For elements of collaboration arrangements that are accounted for pursuant to ASC 808, an arrangement exists, delivery has occurred or services have been rendered,appropriate recognition method is determined and applied consistently.  

In determining the

Our606 noted above.

The Company’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, or VSOE, ofperformance obligation identified in the contract. In developing the stand-alone selling price for a performance obligation, the Company considers competitor pricing for a similar or third-party evidence, or TPE,identical product, market awareness of selling price if VSOE does not exist.

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 ourthe Company’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 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.

R&D reimbursement revenue for revenue attributable to the clinical trials that Celgene has opted into is recognized as delivery or performance of such services occurs.

        ProductMilestone 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 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.

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 collaboration

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.

Acquired In-Process Research and Development Expense
Share-BasedThe Company has acquired rights to develop and commercialize 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, 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 505-50,505‑50, Equity-basedEquity‑based payments to non-employeesnon‑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, 2016,2018, there was $63.2$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 3.432.6 years. As of December 31, 2015,2017, there was $15.63$178.2 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 2.323.4 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 Updateaccordance with ASU 2015-17, Balance Sheet Classification of Deferred Taxes, which requiresall deferred income tax assets and liabilities to beare classified as non-current in a classifiedon the consolidated 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.

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.

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, 20162018, 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, 20162018 by $1.6$2.8 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.

Foreign Currency Exchange Rate Risk

We are exposed to foreign exchange risk arising from various currency exposures. Our functional 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%5.7%, 4.4%appreciation of approximately 6.5% and 2.4%depreciation of approximately 6.3% in the year ended December 31, 2016, 20152018, 2017 and 2014.2016. 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 earnings or losses.


Currency Convertibility Risk

A majority of our expenses and 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'sPeople’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. 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.


Effects of Inflation

Inflation generally affects us by increasing our cost of labor and clinical trial costs. We do not believe that inflation has had a material effect on our results of operations during the year ended December 31, 2016.

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 of 1934, as amended). 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, 2018.

The effectiveness of our internal control over financial reporting as of December 31, 2016. In making2018, 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, 20162018 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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.

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 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

Functional Currency

currency

The determination of the respective functional currency is based on the criteria of Accounting Standard Codification ("ASC"(“ASC”) 830,Foreign Currency Matters.Matters. The functional currency of the Company BeiGene AUS Pty Ltd., BeiGene (Hong Kong) Co., Limited, BeiGene 101 Ltd and BeiGene (USA)all non-PRC subsidiaries is the United States dollar ("(“$" or "U.S. dollar"“U.S. dollar”). The Company'sCompany’s PRC subsidiaries determined their functional currencies to be RMB. The Company uses the U.S. dollar as its reporting currency.

Foreign Currency Translation

currency 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 consists of the secured deposits held in designated banks for issuance of letters of credit and import duty taxes, and cash deposits as security for long-term bank loans.
Accounts Receivable
Trade accounts receivable are recorded at their invoiced amounts, net of 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. No allowance for doubtful accounts was recorded as of December 31, 2018.

Inventory
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, 20162018 and 2015.

2. Summary of significant accounting policies (Continued)

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
Building20 years
Office Equipment5 years
Electronic Equipment3 years
Manufacturing equipment3 to 10 years
Laboratory Equipment3 to 5 years
Computer Software3 to 5 years
Leasehold ImprovementsLesser of useful life or 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 lease prepayments to the PRC government and are carried at cost less accumulated amortization. Land use rights are amortized on a straight-line basis over the shorter of the estimated usage periods or the terms of the land use right.

(Amounts in thousands of U.S. Dollar (“$”) and Renminbi (“RMB”),

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. The Guangzhou land use right is being amortized over the terms of the land use right, which is 50 years. 
In 2018, the Company acquired a second land use right in conjunction with the Innerway asset acquisition (see Note 4). The land use right is being amortized over the remaining 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.
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 year ended December 31, 2018, the Company determined that there were no indicators of impairment of our 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 Celgene Corporation ("Celgene"), ABRAXANE®, REVLIMID®, and VIDAZA®, and its investigational agent CC-122, 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, 2018 and December 31, 2017, the Company determined that there were no 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, 20152018, 2017 and 2014,2016, there was no impairment of the value of the Company'sCompany’s long-lived assets.

The long-term bank loan approximates itsand Shareholder Loan approximate their fair value due to the fact that the related interest rate approximatesrates approximate the raterates currently offered by financial institutions for similar debt instrument of comparable maturities. The warrants and option liabilities were recorded at fair value as determined on the respective issuance dates and subsequently adjusted to the fair value at each reporting date. The senior promissory note and convertible preferred shares were initially recorded at issue price net of issuance costs. Prior to the exercise dates, the Company determined the fair values of the warrants and option liabilities with the assistance of an independent third party valuation firm. 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.

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

Revenue recognition

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 researchthe sale of ABRAXANE®, REVLIMID®, and development collaborative arrangementsVIDAZA® to its product distributor in China. The distributor subsequently resells the products to second tier distributors who ultimately sell the products to health care providers and patients. The Company is the principal under the product sale 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 its first tier distributer. The Company has a single performance obligation which is to sell the products to its first tier distributer. 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 sales rebates and returns using the expected value method. Revenues for product sales are recognized at a point in time when persuasive evidencethe single performance obligation is satisfied upon delivery to the first tier distributer. The Company's payment terms are approximately 90 days. Actual amounts of an arrangement exists, delivery has occurredconsideration 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.
Rebates, including price compensation credits, are offered to distributors, consistent with pharmaceutical industry practices. The Company records 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 services have been rendered,reimbursement amounts (such as provincial acceptance of the fee is fixed or determinable, and there is reasonable assurance thatNational Reimbursement Drug List pricing in the related amounts are collectible in accordance with ASC 605,Revenue Recognition ("ASC 605")PRC). The Company'sCompany regularly reviews the information related to these estimates and adjust the provision accordingly. To date, rebates have not been significant.
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. If the historical 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. 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 it fulfills its obligations under each of its agreements, the Company performs the five step model under ASC 606 noted above.
The Company’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.

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.

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

Due to the uncertainty involved in meeting these development-based targets, they are generally fully constrained at contract inception. 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. 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.

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.

Research and development expenses

Development Expenses

Research and development expenses represent costs associated with the collaborative arrangements, which primarily include (i) payroll and related costs (including share-based compensation) associated with research and development personnel, (ii) costs related to clinical trials and preclinical testing of the Company'sCompany’s technologies under development, (iii) costs to develop the product candidates, including raw materials and supplies, product testing, depreciation, and facility related expenses, (iv) expenses for research services provided by universities and contract laboratories, including sponsored research funding, and (v) other research and development expenses. Research and development expenses are charged to expense as incurred when these expenditures relate to the Company'sCompany’s research and development services and have no alternative future uses.

Clinical trial costs are a significant component of the Company'sCompany’s research and development expenses. The Company has a history of contracting with third parties that perform various clinical trial activities on behalf of the Company in the ongoing development of the Company'sCompany’s product candidates. Expenses related to clinical trials are accrued based on the Company'sCompany’s 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), the Company 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. There were no material adjustments for a change in estimate to research and development expenses in the accompanying consolidated financial statements for the years ended December 31, 2016, 20152018, 2017 and 2014.

Government grants

Grants

Government financial incentives that involve no conditions or continuing performance obligations of the Company are recognized as other non-operating income upon receipt.

In the event government grants or incentives involve continuing performance obligations, the Company will capitalize the payment as a liability and recognize the same financial statement caption as the performance obligation relates over the performance period.

Leases

Leases are classified at the inception date as either a capital lease or an operating lease. The Company assesses a lease to be a capital lease if any of the following conditions exist: a)(a) ownership is transferred to the lessee by the end of the lease term, b)(b) there is a bargain purchase option, c)(c) the lease term is at least 75% of the property'sproperty’s estimated remaining economic life, or d)(d) the present value of the minimum lease payments at the beginning of the lease term is 90% or more of the fair value of the leased property to the lessor at the inception date. A capital lease is accounted for as if there was an acquisition of an asset and an incurrenceoccurrence of an obligation at the inception of the lease. The Company has no capital leases for the years presented.

All other leases are accounted for as operating leases wherein rental payments are expensed on a straight-line basis over the periods of their respective lease terms. The Company leases office space, employee accommodation and manufactory space under operating lease agreements. Certain of the lease agreements contain rent holidays. Rent holidays are considered in determining the straight-line rent expense to be recorded over the lease term. The lease term begins on the date of initial possession of the lease property for purposes of recognizing lease expense on straight-line basis over the term of the lease.

Comprehensive loss

Loss

Comprehensive loss is defined as the changes in equity of the Company during a period from transactions and other events and circumstances excluding transactions resulting from investments by owners and distributions to owners. Among other disclosures, ASC 220,Comprehensive Income,, requires that all items that are required to be recognized under current accounting standards as components of comprehensive loss be reported in a financial statement that is displayed with the same prominence as other financial statements. For each of the periods presented, the Company'sCompany’s comprehensive loss includes net loss, foreign currency translation adjustments and unrealized holding gains/losses associated with the available-for-sale securities, and is presented in the consolidated statements of comprehensive loss.

Stock-based compensation

Share-Based Compensation
Awards granted to employees

The Company applies ASC 718,Compensation—Stock Compensation (" (“ASC 718"718”), to account for its employee share-based payments. In accordance with ASC 718, the Company determines whether an award should be classified and accounted for as a liability award or equity award.

financial statements based on their grant date fair values. Specifically, the grant date fair value of share options areis calculated using an option pricing model. 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. To the extent the required vesting conditions are not met resulting in the forfeiture of the share-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-based compensation expense is recorded net of estimated forfeitures such that expense is recorded only for those share-based awards that are expected to vest. To the extent the Company revises these estimates in the future, the share-based payments could be materially impacted in the period of revision, as well as in following periods. The Company, with the assistance of an independent third partythird-party valuation firm, determined the estimated fair value of the stock options granted to employees.

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. 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 the Company had paid cash for the services provided by the non-employees in accordance with ASC 505-50,Equity-based payments to non-employees. The Company estimated 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, 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 issuedaccordance with Accounting Standards Update (“ASU”) 2015-17,Balance Sheet Classification of Deferred Taxes, which requires all deferred income tax assets and liabilities to beare classified as non-current in a classifiedon the consolidated 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.

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.

the period using the two-class method. Under the two-class method, net income is allocated between ordinary shares and participating securities based on dividends declared (or accumulated) and participating rights in undistributed earnings as if all the earnings for the reporting period had been distributed. The Company's convertible preferredCompany’s restricted shares and restricted stock are participating securities because they have contractual rights to share in the profits of the Company.

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 outstanding during the period. Ordinary equivalent shares consist of the ordinary shares issuable upon the conversion of the Company'sCompany’s convertible preferred shares using the if-converted method, and ordinary shares issuable upon the conversion of the share options and unvested restricted stock,shares, using the treasury stock method. 
Ordinary share equivalents are excluded from the computation of diluted loss per share if their effects would be anti-dilutive. Basic and diluted loss per ordinary share is presented in the Company'sCompany’s consolidated statements of operations.

Segment information

Information

In accordance with ASC 280,Segment Reporting,, the Company'sCompany’s chief operating decision maker, the Chief Executive Officer, reviews the consolidated results when making decisions about allocating resources and assessing performance of the Company as a whole and hence, the Company has only one reportable segment. The Company does not distinguish between markets or segments for the purpose of internal reporting. As the Company's long-lived assets and revenue are substantially located in and derived from the PRC, no geographical segments are presented.

Concentration of risks

Risks

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, 20162018 and 2015, $87,5142017, $712,937 and $17,869$239,602 were deposited with various major reputable financial institutions located in the PRC and international financial institutions outside of the PRC. The deposits placed with financial institutions are not protected by statutory or commercial insurance. In the event of bankruptcy of one of these financial institutions, the Company may be unlikely to claim its deposits back in full.

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.

Foreign currency exchange rate risk

From July 21, 2005, the RMB is permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. For RMB against U.S. dollar, there was depreciation of

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.

prior reporting period presented (the full retrospective method), or retrospectively with the cumulative effect of significantinitially applying the guidance recognized at the date of initial application (the modified retrospective method). On January 1, 2018, the Company adopted the new standard using the modified retrospective method.
The impact to the Company on adoption of the Revenue ASUs relates to variable consideration related to its collaboration agreement with Celgene Corporation ("Celgene") and the anticipated opt-in to certain clinical trials that are to be run by the Company, and funded by Celgene. Under Topic 605, even though the Company believed it was probable that the performance obligation related to the variable consideration would be satisfied as of December 31, 2017, the variable consideration was not realizable because formal notice had not been received. Upon its adoption of the Revenue ASUs, the Company determined it was probable that Celgene would opt-in to the clinical trials as of December 31, 2017 such that the variable consideration was not constrained, and therefore, the related revenue would have been recognized. In March 2018, the Company obtained formal notice of opt-in by Celgene. 
The Company recognized the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of retained earnings. The comparative information has not been restated and continues to be reported under the accounting policies (Continued)standards in effect for those periods. The cumulative effect of the changes made to the Company's consolidated January 1, 2018 balance sheet for the adoption of ASU 2014-9 resulted in an increase of $16,307 to both unbilled receivables and the opening balance of accumulated deficit. Please refer to the “Adoption of New Accounting Standards” section below for a tabular presentation of the impact.
In October 2016, the FASB issued ASU No. 2016-16,

Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which requires the recognition of the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. The Company adopted ASU 2016-16 during the first quarter of 2018 using the modified retrospective adoption method. In 2017, BeiGene HK's contribution of BeiGene Shanghai to BeiGene Biologics (and subsequent receipt of a related government grant) resulted in tax expenses $28,588, which were reflected as other non-current assets in the Company’s December 31, 2017 balance sheet. The related government subsidy of $9,990, which was received in 2017, was reflected as other long-term liabilities in the Company’s December 31, 2017 balance sheet. The adoption of this accounting standard resulted in an adjustment to beginning accumulated deficit for both of these items. In addition, the Company has now established a deferred tax asset resulting from a previous transfer of intellectual property to one of its wholly-owned subsidiaries. This deferred tax asset is entirely offset by a corresponding valuation allowance and therefore did not result in a change to beginning accumulated deficit. Please refer to the “Adoption of New Accounting Standards” section below for a tabular presentation of the impact.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows: Restricted Cash, which requires entities to present the aggregate changes in cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. As a result, the statement of cash flows will be required to present restricted cash and restricted cash equivalents as a part of the beginning and ending balances of cash and cash equivalents. The updated guidance became effective on January 1, 2018, and resulted in the presentation of restricted cash of $27,776 within the ending cash, cash equivalents, and restricted cash balance on the Company’s consolidated statement of cash flows.
In May 2017, the FASB issued ASU No. 2017-9, Compensation – Stock Compensation: Scope of Modification Accounting. This standard provides clarity and reduces both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718, Compensation-Stock Compensation, to a change to the terms or conditions of a share-based payment award. The updated guidance became effective on January 1, 2018, and there was no material impact to the Company’s consolidated financial statements.
In June 2018, the FASB issued ASU 2018-7, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. This update expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. This update also specifies that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. This update is effective in fiscal years, including interim periods, beginning after December 15, 2018. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The Company elected to early adopt this ASU during the quarter ended September 30, 2018, and there was no material impact to the Company's consolidated financial statements.

New accounting standards which have not yet been adopted
In February 2016, the FASB issued ASU No. 2016-02,2016-2, Leases. Subsequently, the FASB issued ASU 2018-1, Land Easement Practical Expedient, which provides an optional transition practical expedient for land easements, ASU 2018-10, Codification Improvements to Topic 842, Leases, which requiresclarifies certain aspects of the guidance issued in ASU 2016-2; ASU 2018-11, Leases (Topic 842): Targeted Improvements, which provides an additional transition method and a practical expedient for separating components of a contract for lessors, and ASU 2018-20, Leases (Topic 842)- Narrow-Scope Improvements for Lessors, which allows certain accounting policy elections for lessors (collectively, the "Lease ASUs"). The Lease ASUs require 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 is effective for interim and annual periods beginning after December 15, 2018, and 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 evaluatingwill adopt the impact on its financial statements of adopting this guidance.

        In March 2016,new standard effective January 1, 2019 using the FASB issued ASU No. 2016-09,Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09"). The amendments in ASU 2016-09 simplify several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities,effective date method and classification on the statement of cash flows. For public business entities, ASU 2016-09 is effective for annual periods beginning after December 15, 2016 and interim periods within those annualwill not restate comparative periods. The Company doeswill elect 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.

Celgene and Celgene Switzerland
On July 5, 2017, the Company entered into a license agreement with Celgene Switzerland pursuant to which the Company granted to the Celgene 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, Celgene and Celgene Switzerland 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 Celgene.
Under the terms of the A&R PD-1 License Agreement, Celgene agreed to pay 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.  In addition, subsequent to the completion of the research and development phase of the collaboration, the Company may be eligible to receive product development milestone payments based on the successful achievement of development and regulatory goals, commercial milestone payments based on the successful achievement of commercialization goals, and royalty payments based on a predetermined percentage of Celgene and Celgene Switzerland’s aggregate annual net sales of all products in their territory for a period not to exceed the latest of the expiration of the last valid patent claim, the expiration of regulatory exclusivity or 12 years from the date of the first commercial sale on a product-by-product and country-by-country basis. 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. 
In addition to the exclusive right to develop and commercialize tislelizumab, the terms of the A&R PD-1 License Agreement provide Celgene 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. The joint development and joint steering committees are formed by an equal number of representatives from the Company and Celgene and are responsible for reviewing and approving the development plan and budget for the development of tislelizumab for clinical studies associated with specified indications. Celgene will reimburse 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 Celgene opts 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 Celgene 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 Celgene 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 Celgene at contract inception and the consideration allocated to the R&D services will be recognized over the term of the respective clinical studies for the specified indications.
The payments associated with the defined developmental, regulatory, and commercialization goals are variable consideration and were fully constrained at contract inception. The Company assesses whether the variable consideration is fully constrained each reporting period based on the facts and circumstances surrounding the achievement of milestones. Upon changes to constraint associated with the milestones, variable consideration will be included in the transaction price when a significant reversal of revenue recognized is not expected to occur and allocated to the separate performance obligations. No revenue was recognized related to the milestones for the year ended December 31, 2018.
For the year ended December 31, 2018, the Company recognized collaboration revenue of $65,835 related to the Celgene collaboration. The Company recognized $56,776 of research and development reimbursement revenue for the year ended December 31,2018 for the trials that Celgene has opted into. In addition, $16,307 of reimbursement that was billed to Celgene was included as an adjustment to beginning accumulated deficit. The Company recognized research and development services revenue of $9,059 for the year ended December 31, 2018, which reflects the recognition of upfront consideration that was allocated to R&D services at the time of the collaboration and is recognized from deferred revenue over the term of the respective clinical studies for the specified indications.
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 Celgene 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.
In 2013, the Company also entered into a license agreement with Merck KGaA, Darmstadt Germany for pamiparib, in which it granted to Merck KGaA, Darmstadt Germany an exclusive license to develop, manufacture, and, in certain circumstances, commercialize pamiparib outside of the PRC, and Merck KGaA, Darmstadt Germany granted the Company an exclusive license to develop, manufacture and commercialize pamiparib in the PRC Territory. 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 of its exclusive rights to pamiparib in the ex-PRC territories for consideration of $10,000, and reduced the future milestone payments the Company was eligible to receive under the PRC license agreement.
In December 2017, the Company achieved the milestone for dosing a patient in the first Phase 2 clinical trial of pamiparib in the PRC Territory, and the related $1,000 milestone payment received in January 2018, was recognized as research and development services revenue in year ended December 31, 2017.
In May 2018, the Company achieved the milestone for dosing patients in the first Phase 3 clinical trial of pamiparib in the PRC Territory, and the related $1,500 milestone payment was recognized as research and development services revenue for the year ended December 31, 2018. No other milestones were achieved prior to the termination of the agreement.
On December 17, 2018, the Company entered into a letter agreement for the Company to buy back the PRC commercialization option for pamiparib it had granted to Merck KGaA, Darmstadt Germany under the license agreement for initial consideration of $19,000. The payment was charged to research and development expense as incurred, as the PRC commercialization option has no alternative future use. As a result of the letter agreement, the license agreement was terminated as of December 31, 2018 and Merck KGaA, Darmstadt Germany was relieved of any future milestone obligations.
As a result of the foregoing termination agreements and notices, as of December 31, 2018, the Company’s license agreements with Merck KGaA, Darmstadt Germany for lifirafenib and pamiparib have been terminated in their entirety.
Zymeworks, Inc.
On November 26, 2018, the Company and Zymeworks entered into collaboration and license agreements whereby the Company acquired licenses to develop and commercialize Zymeworks’ clinical-stage bispecific antibody candidate ZW25 and its preclinical-stage bispecific antibody drug conjugate (ADC) ZW49 in Asia (excluding Japan), Australia, and New Zealand. In addition, Zymeworks granted BeiGene a license to Zymeworks' proprietary Azymetric and EFECT platforms to develop and commercialize globally up to three other bispecific antibodies using the platforms.
Under the collaboration agreements BeiGene will be responsible for all clinical development and regulatory submissions in the licensed territories.

4. Business Combinations and Asset Acquisitions
Celgene Shanghai
On August 31, 2017, BeiGene HK acquired 100% of the equity interests of Celgene Shanghai, a wholly-owned subsidiary of Celgene Holdings East Corporation established under the laws of the PRC. Celgene Shanghai is in the business of, among other things, providing marketing and promotional services in connection with certain pharmaceutical products manufactured by Celgene. The name of Celgene Shanghai has been changed to BeiGene Pharmaceutical (Shanghai).
On July 5, 2017, BeiGene and a wholly-owned subsidiary of Celgene, Celgene Logistics Sàrl (“Celgene Logistics”), entered into a license agreement pursuant to which BeiGene has been granted the right to exclusively distribute and promote Celgene’s approved cancer therapies, ABRAXANE®, REVLIMID®, and VIDAZA®, and its investigational agent CC-122 in clinical development (the “Distribution Rights”), in China excluding Hong Kong, Macau and Taiwan (the “Chinese License Agreement”).

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.

The initial carrying amount of the Series A Preferred Shares of $78,809 was the issue price at the date of issuance of $78,889, net of issuance costs of $80.

Company's ordinary shares. Thewith a fair value equal to a fixed settlement amount, the settlement is not viewed as a conversion option of the convertible preferred shares did not qualify for bifurcation accountingfeature, but as a redemption feature because the conversion optionsettlement amount does not vary with the share price. 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. There wereare no other embedded derivatives that are required to be bifurcated.

        Beneficial conversion features exist when The portion of interest accrued on the conversion price of the convertible preferred shares is lower than the fair value of the ordinary shares at the commitment date, which is the issuance date in the Company's case. When a beneficial conversion feature exists as of the commitment date, its intrinsic value is bifurcated from the carrying value of the convertible preferred shares as a contribution to additional paid-in capital. 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.

        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

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, 20152018, 2017 and 2014.

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.

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 of the Company's initial public offering,Company’s U.S. IPO, the estimated fair value of the ordinary shares, at the option grant dates, was determined with assistance from an independent third party

22. Restricted net assets

Net Assets

The Company'sCompany’s ability to pay dividends may depend on the Company receiving distributions of funds from its PRC subsidiaries. Relevant PRC statutory laws and regulations permit payments of dividends by the Company'sCompany’s PRC subsidiaries only out of its retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. The results of operations reflected in the consolidated financial statements prepared in accordance with GAAP differ from those reflected in the statutory financial statements of the Company'sCompany’s PRC subsidiaries.

In accordance with the company law of the PRC, a domestic enterprise is required to provide statutory reserves of at least 10% of its annual after-tax profit until such reserve has reached 50% of its respective registered capital based on the enterprise'senterprise’s PRC statutory accounts. A domestic enterprise is also required to provide discretionary surplus reserve, at the discretion of the Board of Directors, from the profits determined in accordance with the enterprise'senterprise’s PRC statutory accounts. The aforementioned reserves can only be used for specific purposes and are not distributable as cash dividends. The Company'sCompany’s PRC subsidiaries were established as domestic invested enterprises and therefore were subject to the above mentionedabove-mentioned restrictions on distributable profits.

During the years ended December 31, 2016, 20152018, 2017 and 2014,2016, no appropriation to statutory reserves was made because the PRC subsidiaries had substantial losses during such periods.

As a result of these PRC laws and regulations including the requirement to make annual appropriations of at least 10% of after-tax income and set aside as general reserve fund prior to payment of dividends, the Company'sCompany’s PRC subsidiaries are restricted in their ability to transfer a portion of their net assets to the Company.

Foreign exchange and other regulation in the PRC may further restrict the Company'sCompany’s PRC subsidiaries from transferring funds to the Company in the form of dividends, loans and advances. As of December 31, 20162018 and 2015,2017, amounts restricted are the net assets of the Company'sCompany’s PRC subsidiaries, which amounted to $9,955$93,281 and $3,383,$29,920, respectively.

23. Employee defined contribution plan

        Full timeDefined Contribution Plans

Full-time employees of the Company in the PRC participate in a government mandated defined contribution plan, pursuant to which certain pension benefits, medical care, employee housing fund and other welfare benefits are provided to employees. Chinese labor regulations require that the Company'sCompany’s PRC subsidiaries make contributions to the government for these benefits based on certain percentages of the employees'employees’ salaries. The Company has no legal obligation for the benefits beyond the contributions made. The total amounts for such employee benefits, which were expensed as incurred, were $2,148, $1,443$12,713, $4,103 and $1,030$2,148 for the years ended December 31, 2018, 2017 and 2016, 2015 and 2014, respectively.
During the year ended December 31, 2016, the Company implemented a defined contribution 401(k) savings plan (the "401(k) Plan") for U.S. employees. The 401(k) Plan covers all U.S. employees, and allows participants to defer a portion of their annual compensation on a pretax basis. In addition, the Company implemented a matching contribution to the 401(k) Plan, matching 50% of an employee's contribution up to a maximum of 3% of the participant's compensation. Company contributions to the 401(k) plan totaled $0.1 million$1,275, $455 and $79 in the yearyears ended December 31, 2016. The Company did not have a
