Cancer Background and Market Size
Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells, which can result in death. The development of cancer is multi-factorial and includes both external factors (tobacco, infectious organisms, chemicals, and radiation) and internal factors (inherited mutations, hormones, immune conditions, and mutations that occur from exposure to environmental factors or errors in making DNA (deoxyribonucleic acid) during normal cell division). These causal factors may act together or in sequence to initiate or promote the development of cancer. Ten or more years often pass between exposure to these factors and the development of detectable cancer. Cancer is treated through surgery, radiation, chemotherapy, hormone therapy, immunotherapy, and/or targeted drug therapy.
According to the American Cancer Society’s publication Cancer Facts & Figures 20182021, cancer is the second leading cause of death in the U.S. (only behind heart disease). In the U.S., approximately 1.71.9 million new cancer cases wereare expected to be diagnosed in 20182021 and approximately 610,000608,570 persons were expected to die from the disease. Anyone can develop cancer. Since the risk of being diagnosed with cancer increases with age, most cases occur in adults who are middle aged or older. About 87%80% of all cancers are diagnosed in people 5055 years of age andor older. In the U.S., approximately 4041 out of 100 men and 3839 out of 100 women will develop cancer during their lifetime. These probabilities are estimated based on the overall experience of the general population. Individuals within the population may have higher or lower risk because of differences in exposures (e.g., smoking), and/or genetic susceptibility. In addition, currently available treatments are variably effective in thefor different

cancers and individual patients. Together these patients’ risks and the treatment limitations suggest a significant current and long-term demand for improved and novel cancer treatments.

Commercialized Products
FUSILEV
FUSILEV (levoleucovorin) is a novel folate analog and the pharmacologically active isomer (the levo-isomer) of the racemic compound, calcium leucovorin. Leucovorin is a mixture of equal parts of both isomers: the pharmacologically active levo-isomer and the inactive dextro-isomer. Preclinical studies have demonstrated that the inactive dextro-isomer may compete with the active levo-isomer for uptake at the cellular level. By removing the inactive dextro form, the dosage of FUSILEV is one-half that of leucovorin and patients are spared the administration of an inactive substance. FUSILEV is approved as a ready-to-use solution, and as freeze-dried powder. FUSILEV has the following indications for use:
in combination chemotherapy with 5-fluorouracil in the palliative treatment of patients with advanced mCRC;
for rescue after high-dose methotrexate, or MTX, therapy in osteosarcoma; and
to diminish the toxicity and counteract the effects of impaired MTX elimination and of inadvertent over dosage of folic acid antagonists.
Effective December 2018, FUSILEV has been discontinued and we are no longer selling this product. We have since transitioned to marketing KHAPZORY (see below) for identical indications as FUSILEV.
KHAPZORY
On October 19, 2018, the FDA approved KHAPZORY (levoleucovorin), which is formulated as a freeze-dried powder. KHAPZORY is a novel folate analog and the pharmacologically active levo-isomer of d,1-leucovorin. Preclinical studies have

demonstrated that the inactive dextro-isomer may compete with the active levo-isomer for uptake at the cellular level. By removing the inactive dextro form, the dosage of KHAPZORY is one-half that of leucovorin and patients are spared the administration of an inactive substance. While FUSILEV uses a calcium-based formulation, KHAPZORY uses a sodium-based formulation, though has the same indications for use as FUSILEV.
FOLOTYN
FOLOTYN (pralatrexate injection), a folate analogue metabolic inhibitor, was discovered by Memorial Sloan-Kettering Cancer Center, SRI International and Southern Research Institute, and was developed by Allos Therapeutics, Inc., or Allos. In September 2009, the FDA granted accelerated approval for FOLOTYN for use as a single agent for the treatment of patients with relapsed or refractory peripheral T-cell lymphoma, or PTCL. FOLOTYN was the first chemotherapy approved by the FDA, under its accelerated approval program, for the treatment of relapsed or refractory PTCL and has been available to patients in the U.S. since October 2009.
According to the Lymphoma Research Foundation, lymphoma is the most common blood cancer. Hodgkin’s lymphoma and NHL are the two main forms of lymphoma. Lymphoma occurs when lymphocytes, a type of white blood cell, grow abnormally and accumulate in one or more lymph nodes or lymphoid tissues. The body has two main types of lymphocytes that can develop into lymphomas: B-lymphocytes, or B-cells, and T-lymphocytes, or T-cells. PTCL comprises a group of rare and aggressive NHLs that develop from mature T-cells and accounts for approximately 5 to 15% of all NHL cases in the U.S. and Europe.
Based on preclinical studies, we believe that FOLOTYN selectively enters cancer cells expressing reduced folate carrier, or RFC-1, a protein that is frequently over expressed on cancer cells compared to normal cells. Once inside cancer cells, FOLOTYN is efficiently polyglutamylated and retained inside the cells for a longer time. FOLOTYN and its polyglutamates inhibit dihydrofolate reductase, or DHFR, an enzyme critical in the folate pathway, thereby interfering with DNA and RNA synthesis and triggering cancer cell death.
The safety and efficacy of FOLOTYN was evaluated in an open-label, single-arm, multi-center, international trial that enrolled patients with relapsed or refractory PTCL. One hundred and eleven patients were treated with FOLOTYN at 30 mg/m² once weekly by IV push over three to five minutes for six weeks in seven-week cycles until disease progression or unacceptable toxicity. Of the 111 patients treated, 109 patients were evaluable for efficacy. The primary efficacy endpoint was overall response rate (complete response, complete response unconfirmed, and partial response) as assessed by International Workshop Criteria, or IWC. Of the 109 evaluable patients, 27% of patients achieved a response that met these criteria.
In addition to its approved indication, FOLOTYN is being investigated in a Phase 1 study in combination with the CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) chemotherapy regimen. Once the proper dose of FOLOTYN in combination with CHOP has been determined, a Phase 3 study of the combinations of FOLOTYN and CHOP, and BELEODAQ and CHOP, compared to CHOP alone for the treatment of first line PTCL may be initiated. The Phase 1 study and the Phase 3 study concept are also the current post-marketing requirements for the FDA’s accelerated approval of our currently marketed indication for FOLOTYN.
BELEODAQ
BELEODAQ (belinostat) is a histone deacytelase, or HDAC, inhibitor for the treatment of patients with relapsed or refractory PTCL. This indication was FDA approved in July 2014 under its accelerated approval program, based on tumor response rate and duration of response. BELEODAQ's anticancer effect is thought to be mediated through multiple mechanisms of action, including the inhibition of cell proliferation, induction of apoptosis (programmed cell death), inhibition of angiogenesis, induction of differentiation, and the activity in tumors that had become resistant to anticancer agents such as the platinums, taxanes, and topoisomerase II inhibitors.

The safety and effectiveness of BELEODAQ was evaluated in an open-label, single-arm, non-randomized international trial involving 129 participants with relapsed or refractory PTCL. Patients were treated with BELEODAQ 1,000 mg/m2 administered over 30 minutes via IV infusion once daily on days one to five of a 21-day cycle until disease progression or unacceptable toxicity. The primary efficacy endpoint was response rate (complete response and partial response) as assessed by an independent review committee, or IRC, using IWC. In all evaluable patients (N = 120) treated with BELEODAQ, the overall response rate per central review using IWC was 25.8%.

We market FOLOTYN and BELEODAQ for the treatment of relapsed or refractory PTCL. These drugs have different mechanisms of action, and as a result, the treating physician may prefer to start treatment with one drug over the other. In

4

Table of Contents


addition, physicians may prefer one drug over another based on specific patient factors such as the subtype of PTCL being treated, existing comorbidities, or the performance status of the patient. However, both drugs have similar response rates of approximately 25-30%. It is common for patients to cycle through multiple drugs, including both FOLOTYN and BELEODAQ, though these drugs are not FDA-approved for use in combination with one another.

In addition to its approved indication, BELEODAQ has been investigated in a Phase 1 study in combination with the CHOP chemotherapy regimen. Once the proper dose of FOLOTYN in combination with CHOP has been determined, a Phase 3 study may be assessed for the combination of BELEODAQ and CHOP and FOLOTYN and CHOP, compared to CHOP alone for the treatment of first line PTCL. The Phase 1 study and the Phase 3 study concept are also the current post-marketing requirements for the FDA's accelerated approval of our currently marketed indication for BELEODAQ.
ZEVALIN
ZEVALIN (ibritumomab tiuxetan) injection for intravenous use is a prescription medication that is part of a three step treatment regimen consisting of: two treatments of Rituximab and one treatment of Yttrium-90 (Y-90) ZEVALIN. The National Cancer Institute, or NCI, estimated 75,000 new cases of NHL in the U.S. in 2018. Rituximab is used to reduce the number of B-cells in the blood and Y-90 ZEVALIN is then given to treat NHL. It is currently approved in the U.S. and more than 40 countries outside the U.S. including countries in Europe, Latin America and Asia for (i) treatment of patients with recurring, low-grade or follicular B-cell NHL after other anticancer drugs are no longer working, and (ii) newly diagnosed follicular NHL following a response to initial anticancer therapy.

MARQIBO
MARQIBO (vincristine sulfate liposome injection) is a novel, sphingomyelin/cholesterol liposome-encapsulated formulation of the FDA-approved anticancer drug Vincristine. MARQIBO’s approved indication is for the treatment of adult patients with Philadelphia chromosome-negative - ALL, or Ph-ALL, in second or greater relapse or whose disease has progressed following two or more lines of anti-leukemia therapy. According to the NCI, in 2018 it is estimated that there will be approximately 6,000 patients diagnosed with ALL in the U.S., of which approximately 1,600 can be categorized as ALL in second or greater relapse.
MARQIBO was studied in an international, open-label, multi-center, single-arm trial. Eligible patients were 18 years of age or older with Ph-ALL in second or greater relapse or whose disease progressed after two or greater treatment lines of anti-leukemia therapy. Patients received intravenous MARQIBO monotherapy at 2.25 mg/m2 over 60 minutes every seven days. The treated population included 65 patients who received at least one dose of MARQIBO. Of the 65 evaluable patients, three (4.6%) achieved complete remission, or CR, seven (10.8%) achieved complete remission with incomplete blood count recovery, or CRi, for a total of 10 (15.4%) total patients who achieved a CR or CRi.
In addition to its approved indication, MARQIBO is being investigated in pediatric ALL in a Phase 1 investigator-initiated study in the U.S. Based on data from this study, Spectrum will determine whether to conduct a registration study for MARQIBO in this setting. We are in discussions with the FDA regarding the possibility of using this development plan to satisfy one of the post-marketing requirements for the accelerated approval of our currently marketed indication for MARQIBO.
MARQIBO is also being investigated in diffuse large B-cell lymphoma in a Phase 3 investigator-initiated study in Europe in combination with the standard CHOP chemotherapy regimen in Europe, CHOP-14. Based on interim data from this study, Spectrum will consider whether to conduct a study of the combination of MARQIBO with the standard CHOP regimen in the U.S., CHOP-21 may be initiated.
EVOMELA
EVOMELA is intended for use as a high-dose conditioning treatment prior to autologous stem cell transplant, or ASCT, for patients with MM. MM is a cancer of plasma cells, a type of white blood cell present mainly in the bone marrow that produces antibodies. In MM, a group of plasma cells (myeloma cells) become cancerous and multiply, raising the number of plasma cells to a higher-than-normal level, which can crowd out normal blood cells and lead to abnormally high proteins in the blood or urine. The NCI estimated 31,000 new cases of MM in the U.S. in 2018, with the incidence of new cases increasing by approximately 2% per year.

Table of Contents


The EVOMELA formulation avoids the use of propylene glycol, or PG, which is required as a co-solvent in the currently-available formulation of this product. The use of Betadex Sulfobutyl Ether Sodium technology to reformulate EVOMELA may allow for longer administration durations and slower infusion rates, potentially enabling clinicians to avoid reductions.
EVOMELA was approved by the FDA based on its bioequivalence to the standard melphalan formulation (Alkeran) via the new drug regulatory pathway provided by Section 505(b)(2) of the Federal Food, Drug and Cosmetic Act. The safety and effectiveness of EVOMELA in high-dose conditioning treatment was evaluated in an open-label, single-arm, non-randomized trial. The objective of the trial was to determine the overall safety and toxicity profile of 200 mg/m2 of EVOMELA in patients with MM undergoing ASCT. The overall response rate (partial response or better) improved from 79% prior to the ASCT procedure to 95% at 90 to 100 days post-transplant. There was also an increase in the number of patients with a stringent complete response from zero patients prior to the ASCT procedure to 16% at 90 to 100 days post-transplant. Myeloablation, neutrophil engraftment, and platelet engraftment were achieved by all 61 patients. Myeloablation occurred on day five of ASCT (range of ASCT days was one to six) with the median time to myeloablation from dosing of eight days. The median time to neutrophil engraftment was 12 days (range of ASCT days was 10 to 16). The median time to platelet engraftment was 13 days (range of ASCT days was 10 to 28).

PoziotinibEflapegrastim

Poziotinib is a novel, pan-HER inhibitor that irreversibly blocks signaling through the Epidermal Growth Factor Receptor (EGFR, HER) Family of tyrosine-kinase receptors, including HER1 (erbB1; EGFR), HER2 (erbB2), HER4 (erbB4), and HER receptor mutations. This, in turn, leadsEflapegrastim (previously referred to the inhibition of the proliferation of tumor cells that over-express these receptors. Mutations or over-expression/amplification of EGFR family receptors have been associated with a number of different cancers, including NSCLC, breast cancer, and gastric cancer.

Our clinical development program for poziotinib is focused on four pillars, including previously treated NSCLC, first-line treatment of NSCLC, combination therapy and treatment of other solid tumors with EGFR or HER2 mutations. Specifically, we are investigating poziotinib for the treatment of NSCLC tumors with either EGFR or HER2 exon-20 insertion mutations. NSCLC tumors with EGFR or HER2 exon-20 insertion mutations are rare, and have generally not been responsive to other tyrosine kinase inhibitors. Patients with these mutations have a poor prognosis, and available treatment options are limited. Poziotinib, due to its unique chemical structure and characteristics, is believed to inhibit cell growth of EGFR or HER2 exon-20 insertions. In collaboration with The University of Texas MD Anderson Cancer Center ("MD Anderson"), an investigator-sponsored Phase 2 trial was initiated in NSCLC patients with EGFR or HER2 exon-20 mutations (the "MD Anderson Phase 2 Trial"). The EGFR cohort of 50 patients has completed enrollment; the enrollment of the HER2 cohort of 30 patients is ongoing. In addition to the MD Anderson study, we have ongoing pivotal Phase 2 global study with active sites in the U.S., Canada, and Europe ("ZENITH20").
In April 2018, poziotinib data were published in Nature Medicine from the ongoing study led by MD Anderson, which provided an update on the preliminary clinical data of poziotinib dosing on the 11 NSCLC patients previously reported at World Conference on Lung Cancer in October 2017. This publication summarized the current preclinical and clinical data with poziotinib for EGFR or HER2 exon-20 mutations. MD Anderson utilized in silico, in vitro, and in vivo testing to model structural alterations induced by exon-20 mutations and identify potentially effective inhibitors. 3-D modeling indicated alterations restricted the size of the drug binding pocket, limiting the binding of large, rigid inhibitors. It was found that poziotinib, due to its small size and flexibility, can circumvent these steric changes, and is a potent inhibitor of the most common EGFR and HER2 exon-20 mutants. Poziotinib demonstrated greater activity than approved EGFR tyrosine kinase inhibitors ("TKIs") in vitro and in EGFR or HER2 exon-20 mutant patient-derived xenograft models, and genetically engineered mouse models of NSCLC.

In September 2018 we announced preliminary poziotinib data from the MD Anderson Phase 2 NSCLC study which were released during an oral presentation at the IASLC 19th World Conference on Lung Cancer. The MD Anderson study is the single largest data set of patients with an exon 20 mutation in EGFR or HER2.  This Phase 2 study demonstrated high anti-tumor activity for poziotinib in metastatic, heavily pretreated EGFR exon 20 mutant NSCLC, a group for which no targeted agents have proven to be effective to date. This data is summarized below:
In 44 evaluable patients with EGFR exon-20 mutations, the confirmed overall response rate (ORR) was 43% and disease control rate was 90%. Median progression free survival (PFS) was 5.5 months (ITT).
In evaluable patients with HER2 exon-20 mutations, the confirmed overall response rate (ORR) was 42% and disease control rate was 83%. Median progression free survival (PFS) was 5.1 months (ITT).

EGFR-related toxicities (including rash, diarrhea, and paronychia) were manageable and required dose reductions in 60% of patients. Discontinuation due to poor tolerance was rare (approximately 3% of patients).

On January 2, 2019 we announced full enrollment of cohort 1 (N=87) for previously treated NSCLC patients with EGFR exon 20 insertion mutations with sites across the U.S., Europe, and Canada. The EGFR previously treated cohort is part of the ZENITH20 trial - an open-label, multi-center, global Phase 2 trial evaluating NSCLC patients with EGFR or HER2 exon 20 insertion mutations. Results from this cohort are expected by the second half of 2019.
We have also been studying poziotinib in patients with HER2+ breast cancer, however we are no longer focusing on studying poziotinib in this group of patients as the unmet need is not as significant as it is for patients with EGFR or HER2 exon 20 insertion mutations. A Phase 2 study including patients with HER2+ metastatic breast cancer, who have failed at least two HER2 directed therapies, has been fully enrolled. A Phase 1b study testing the combination of poziotinib and ado-trastuzumab emtansine (T-DM1) in patients with metastatic breast cancer has now been closed to further enrollment.

In December 2015, we reached agreement withWe submitted our BLA for eflapegrastim to the FDA regarding ouron October 24, 2019. Our BLA is supported by data from two similarly designed Phase 3 Special Protocol Assessment, or SPA,clinical trials, ADVANCE and RECOVER, which evaluated the safety and efficacy of eflapegrastim in 643 early-stage breast cancer patients for ROLONTIS. This pivotal Phase 3 study (ADVANCE Study, or SPI-GCF-301) was initiated in the first quartertreatment of 2016neutropenia due to evaluate ROLONTIS as a treatment for chemotherapy-induced neutropenia. We announced in February 2018 that the top line results of this studymyelosuppressive chemotherapy. Both studies met the non-inferiority of ROLONTIS to pegfilgrastim endpoint in the Duration of Severe Neutropenia, or DSN, across all four cycles (all p<0.0001). We initiated a second pivotal Phase 3 study (RECOVER Study, or SPI-GCF-302) and announced in June 2018, that it had also met its primary efficacypre-specified endpoint of non-inferiority in DSN between ROLONTISduration of severe neutropenia and met all of the secondary endpoints. In addition, the safety profile was similar to pegfilgrastim. On August 6, 2021, we announced the receipt of a CRL based on manufacturing deficiencies identified at both the drug substance and drug product manufacturers. The Company believes these manufacturing deficiencies have been remediated and on March 11, 2022, we resubmitted the BLA for eflapegrastim.

We submitted our Biologics License Application ("BLA")A company sponsored clinical trial has been initiated to evaluate the administration of eflapegrastim on the same day as chemotherapy. This Phase 1 clinical trial is a randomized, open label, actively controlled study to evaluate the same-day dosing of eflapegrastim on duration of neutropenia when administered at varying intervals following docetaxel and cyclophosphamide (TC) chemotherapy in patients with early-stage breast cancer. On March 4, 2021, at the FDAvirtual 38th Annual Miami Breast Cancer Conference®, the Company presented positive early data showing rapid absolute neutrophil count (ANC) recovery in late December 2018. Duethe first three patients dosed in the 30-minute arm of the same-day dosing. This arm met the prespecified interim safety evaluation criteria and therefore supported the expansion of this arm to 15 patients. The study design included an interim safety evaluation that was conducted once the first three patients in each arm (30 minutes, 3 hours, or 5 hours) completed Cycle 1. Based on this review, the 30-minute arm expanded to a total of 15 patients, while the 3- and 5-hour dosing arms have been discontinued. In the 30-minute dosing arm, ANC recovery was more rapid compared to the recent federal government shutdown,3- and 5-hour arms. ANC nadir was also deeper and longer for the BLA3- and 5-hour arms compared to the 30-minute arm. The overall safety profile for the 30-minute arm was officially received by the FDA on January 28, 2019. Once this BLA is accepted by the FDA, our Prescription Drug User Fee Act date is expectedsimilar to be set for 10 months thereafter.what has been seen previously in large randomized studies with G-CSF given 24 hours after chemotherapy.

QAPZOLA
Poziotinib is a potent tumor-activated drugnovel, pan-HER inhibitor that is being testedirreversibly blocks signaling through the Epidermal Growth Factor Receptor (EGFR) family of tyrosine-kinase receptors, including HER1 (erbB1; EGFR), HER2 (erbB2), HER4 (erbB4), and HER receptor mutations. This, in non-muscle invasive bladder cancer ("NMIBC"). The NCI estimates that the 2018 incidence and prevalence of bladder cancer in the U.S. was approximately 79,000 cases. The global presence of bladder cancer is estimated at 2.7 million cases. According to Botteman et al., (PharmacoEconomics 2003), bladder cancer is the most expensive cancer to treat on a lifetime basis. The overall cost of bladder cancer treatment in the U.S. is approximately $3.4 billion annually, most of which is relatedturn, leads to the direct treatment of this disease.
The initial treatment of bladder cancer is to attempt a complete surgical removalinhibition of the tumor. However, bladder cancer is a highly recurrent disease with approximately 80%proliferation of patients recurring within five years, and a majority of patients recurring within two years. This high recurrence rate is attributed to:
the highly implantable nature of cancertumor cells that are dispersed during surgery;over-express these receptors. Mutations of over-expression/amplification of EGFR family receptors have been associated with a number of different cancers, including NSCLC, breast cancer, and gastric cancer. In March 2015, we entered into a co-development and commercialization agreement with Hanmi for poziotinib worldwide rights, except in Korea and China.

Our clinical development program for poziotinib is focused on previously treated NSCLC, first-line treatment of NSCLC and treatment of other solid tumors with HER2 mutations. NSCLC tumors with HER2 exon 20 insertion mutations are rare and have generally not been responsive to other tyrosine kinase inhibitors. Patients with these mutations have a poor prognosis, and available treatment options are limited. Poziotinib, due to its unique chemical structure and characteristics, is believed to inhibit cell growth of tumors with HER2 exon-20 insertion mutations.
tumors present in multiple locationsIn October 2017, we announced the start of a pivotal Phase 2 global clinical trial with active sites in the bladder which may be missedU.S., Canada and Europe (“ZENITH20”). The ZENITH20 trial consists of seven cohorts of NSCLC patients. Cohorts 1, 2, 3 and 4 have completed enrollment while Cohorts 5, 6, and 7 are currently enrolling patients. Cohorts 1 (EGFR) and 2 (HER2) include previously treated NSCLC patients with exon 20 mutations. Cohort 3 (EGFR) and 4 (HER2) include first-line NSCLC patients with exon 20 mutations. Cohorts 1- 4 are each independently powered for a pre-specified statistical hypothesis and the primary endpoint is objective response rate (“ORR”). Cohort 5 includes previously treated or too small to visualizetreatment-naïve NSCLC patients with EGFR or HER2 exon 20 insertion mutations and is evaluating different dosing regimens. Cohort 6 includes NSCLC patients with classical EGFR mutations who progressed while on treatment with first-line osimertinib and developed an additional EGFR mutation. Cohort 7 includes NSCLC patients with a variety of less common mutations in EGFR or HER2 exons 18-21 or the extracellular or transmembrane domains.

On December 26, 2019, we announced that the pre-specified primary endpoint was not met in Cohort 1 of the ZENITH20 trial evaluating poziotinib in previously treated NSCLC patients with EGFR exon 20 insertion mutations. Cohort 1 enrolled a total of 115 patients who received 16 mg/day of poziotinib. The intent-to-treat analysis showed that 17 patients had a response (by RECIST) and 62 patients had stable disease for a 68.7% disease control rate (“DCR”). The confirmed ORR was 14.8% (95% Confidence Interval (“CI”) 8.9%-22.6%). The median duration of response was 7.4 months and the progression free survival was 4.2 months. The safety profile was in-line with other second-generation EGFR tyrosine kinase inhibitors.

On July 27, 2020, we announced that we met the pre-specified primary endpoint for Cohort 2 in the ZENITH20 trial evaluating previously treated NSCLC patients with HER2 exon 20 insertion mutations. Cohort 2 enrolled a total of 90 patients who received an oral, once daily dose of 16 mg of poziotinib. All the patients had failed at least one line of prior systemic therapy with 60 patients (67%) having failed two or more prior therapies, including chemotherapy and immunotherapy. All responses were read independently and confirmed by a central imaging laboratory using RECIST criteria. The intent-to-treat analysis demonstrated a confirmed ORR of 27.8% (95% CI of 18.9%-38.2%). Based on the pre-specified statistical hypothesis for the primary endpoint, the observed lower bound of 18.9% exceeded the pre-specified lower bound of 17% in this heavily pre-treated population. The safety profile was in-line with the type of adverse events seen with other second-generation EGFR tyrosine kinase inhibitors. These results were presented at the European Society for Medical Oncology (ESMO) Virtual Congress 2020 Science Weekend held in September 2020.
In December 2020, we reported that its pre-specified primary endpoint in Cohort 3 evaluating poziotinib in first-line NSCLC patients with EGFR exon 20 insertion mutations was not met. Cohort 3 of the ZENITH20 clinical trial enrolled a total of 79 patients who received an oral once daily dose of 16 mg of poziotinib. The median time of resection.
Despite evidence in the published literaturefollow up of all patients was 9.2 months with 12 ongoing patients still on treatment. The intent-to-treat analysis showed that 22 patients had a partial response (by RECIST) and guidance from the American and European Urology Associations, instillation of a chemotherapeutic agent immediately following surgery is not a standard clinical practice. Currently, there are no FDA approved drugs68 patients had stable disease for this indication which may, in part, explain the difference between the literature and urology guidelines and actual clinical management of this disease. For more than 30 years, no new drugs have been introduced in the market for treatment of NMIBC. QAPZOLA represents much needed therapy for patients and may provide a meaningful opportunity to reduce overall medical costs.
Pharmacokinetic studies have verified that QAPZOLA is rarely detectable in the bloodstreaman 86.1% DCR. 91% of patients when it is administered either after surgical resection or asexperienced tumor reduction with a partmedian reduction of a delayed multi-instillation protocol.

The proposed dose therefore carries a minimal riskmedian duration of systemic toxicityresponse was 6.5 months and the median progression free survival was 7.2 months. The safety profile was similar with the type of adverse events observed with other second-generation EGFR tyrosine kinase inhibitors. Grade 3 treatment related rash was 33% and diarrhea was 23%. 94% of patients had drug interruptions with 6 patients (8%) permanently discontinuing due to adverse events.
In March 2021, we announced that could arisethe FDA granted Fast Track designation for Poziotinib based on data from absorptionCohort 2 of a drug throughZENITH20, which evaluated previously treated patients with NSCLC with HER2 exon 20 insertion mutations. On December 6, 2021, we announced the bladder wall into the bloodstream. An immediate instillationsubmission of QAPZOLA may help by:
reducing tumor recurrence by destroying dispersed cancer cells that would otherwise re-implant onto the inner lining of the bladder;
destroying remaining cancer cells at the site of tumor resection (also known as chemo-resection); and
destroying tumors not observed during resection (also known as chemo-ablation).
We submitted anits NDA on December 11, 2015, which was accepted on February 9, 2016. In November 2016, we received a Complete Response Letter, or CRL, from the FDA. In February 2017, we received a SPA fromfor poziotinib to the FDA for our redesigned Phase 3 studyuse in patients with previously treated locally advanced or metastatic NSCLC with HER2 exon 20 insertion mutations. The NDA submission is based on the positive results of QAPZOLA. The new Phase 3 study has been specifically designed to build on learningsCohort 2 from the previous studies as well as recommendations fromZENITH20 clinical trial, which assessed the FDA. The Phase 3 study is currently enrolling up to 425 evaluablesafety and efficacy of poziotinib. On February 11, 2022, the Company announced that the file had been accepted and an action date of November 24, 2022 had been set.
In March 2022, the Company presented the results of Cohort 4 at the ESMO Targed Anticancer Therapies (“TAT”) meeting. Cohort 4 of the ZENITH20 clinical trial enrolled a total of 70 patients, using a single48 of whom received an oral once daily dose of 16 mg of poziotinib and 22 of who received an oral twice daily dose of 8 mg of QAPZOLA, and will evaluate time-to-recurrence aspoziotinib.

Manufacturing
We currently do not have internal manufacturing capabilities; therefore, allcapabilities. All of our products areare/were manufactured on a contract basis.by third parties that specialize in these services. We expect to continue to contract with third-party providersthird-parties for our manufacturing and packaging services,requirements, including active pharmaceutical ingredients or API,(API) and finished-dosage products. We believe that our current agreements with third-party manufacturers provide for sufficient operating capacity to support our clinical requirements and the anticipated commercial demand and clinical requirements for our products. Where technically feasible, we maintain secondary supplier sources for our drug products to mitigate the risk of over-reliance on any onesingle supplier. We attempt to prevent supply disruption through our executed supply agreements, appropriate forecasting, and maintaining base stock levels.

Sales and Marketing
We presently market our pharmaceutical products through group purchasing organizations, or GPOs, wholesalers or directly to major hospitals and cancer centers in the U.S., except for our U.S. sales of ZEVALIN, in which case we sell directly to the end-user; and through distributors in Europe (and previously in Japan). Most of our revenues are derived from sales within the U.S. For information regarding the portion of our revenue attributable to sales outside the U.S., see Note 5, "Composition of Total Revenue," to our accompanying Consolidated Financial Statements. Our U.S. sales team is divided between “corporate accounts” and “oncology accounts” that generally interact with different end-user types. The primary decision makers for our products are oncologists and hematologists. As of December 31, 2018, our U.S. sales force (sales management, sales representatives, and sales administrative support) numbered 61 employees.

Competition
The pharmaceutical industry is characterized by rapidly-evolving technology and intense competition, which we expect will continue.to persist. Many companies are engaged in research and development of compounds that are similar to ours – both commercialized and in development, which fosters continuous innovation. In the event that one or more of our competitor’s programs are successful, the market for some of our drug products could be reduced or eliminated. Any product for which we obtain FDA approval must also compete for market acceptance and market share.
SuccessfulOur successful marketing of branded products, upon FDA approval, depends primarily on the ability to communicate the effectiveness, safety, and value of the products to healthcare professionals in private practice, group practices, hospitals, academic institutions, and managed care organizations. Competition for branded drugs is less driven by price and is more focused on innovation in treatment of disease, advanced drug delivery, and specific clinical benefits over competitive drug therapies. Unless our products are shown to be differentiated, i.e., have a better safety profile, efficacy, and cost-effectiveness, compared to other alternatives, they may not gain acceptance by medical professionals and may therefore never be commercially successful.

Companies that have products on the market or in research and development that target the same indications as our in-development products or new compounds sought include, among others, AstraZeneca plc, Bayer AG, Endo International plc, Eli Lilly and Company, Novartis International AG, Genentech, Inc. (Roche Holding AG), Bristol-Myers Squibb Company, Seattle Genetics, Inc., GlaxoSmithKline plc, Biogen Inc., OSI Pharmaceuticals, Inc. (Astellas Pharma Inc.), Cephalon, Inc.

Each of the aforementioned companies may be more advanced in the development of competing drug products. Many of these competitors are large and well-capitalized companies focusing on a wide range of cancers and drug indications,cancer types and have substantially greater resources and expertise than we do.
We believe that the current competitive landscape for each of our commercialized products, and key in-development products, is as follows:
(a)
KHAPZORY is the sodium levo-isomeric form of the racemic compound calcium, leucovorin, a product already approved for the same indication as FUSILEV. There are several generic companies approved by the FDA to sell the calcium leucovorin product, we are competing with lower-cost alternatives.

(b)
ZEVALIN has two competitive products for its currently approved indications:


Rituxan® (rituximab), marketed by Genentech Inc. and Biogen Inc., is indicated for the treatment of patients with relapsed or refractory, low-grade or follicular, CD20-positive, B-cell NHL as a single agent; previously untreated follicular, CD20-positive, B-cell NHL in combination with CVP (cyclophosphamide, vincristine and prednisone combination) chemotherapy; and non-progressing (including stable disease), low-grade, CD20-positive B-cell NHL, as a single agent, after first-line CVP chemotherapy. Rituxan is administered as a part of various chemotherapy regimens and schedules, the vast majority of which, could be used in concert with other therapeutic agents, such as ZEVALIN, as part of a treatment plan.

Bendeka® (bendamustine hydrochloride) for Injection, for Intravenous Infusion, marketed by Teva Pharmaceutical Industries Ltd., is indicated for the treatment of patients with indolent B-cell NHL that has progressed during or within six months of treatment with rituximab or a rituximab-containing regimen.

(c)
FOLOTYN, was the first agent approved by the FDA for treatment of patients with relapsed or refractory PTCL. BELEODAQ is a HDAC inhibitor, also indicated for the treatment of patients with relapsed or refractory PTCL. Both drugs were approved under accelerated approval based on tumor response rate. Clinical benefit such as improvement in progression-free survival or overall survival has not been demonstrated. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

There are many existing approaches used in the treatment of relapsed or refractory PTCL, including combination chemotherapy and single agent regimens, which represent competition for FOLOTYN and BELEODAQ. Both drugs have two primary competitive products for their currently approved indications:

Istodax® (Romidepsin), marketed by Celgene Corporation, was granted accelerated approval by the FDA in June 2011 for the treatment of patients with PTCL who have received at least one prior therapy.

Adcetris® (Brentuximab vedotin), marketed by Seattle Genetics, Inc., was granted accelerated approval by the FDA in August 2011 for the treatment of patients with systemic anaplastic large cell lymphoma, or ALCL, after failure of at least one prior multi-agent chemotherapy regimen. ALCL is one of the subtypes of PTCL included in the labels of FOLOTYN, BELEODAQ and Istodax.
We are aware of multiple investigational agents that are currently being studied in clinical trials for PTCL which, if approved, may compete with FOLOTYN and BELEODAQ. Many patients with PTCL do not adequately respond to a single treatment agent, so many patients receive treatment with more than one agent (e.g., BELEODAQ and FOLOTYN).
(d)
MARQIBO is a liposomal form of standard vincristine. In its current indication, MARQIBO is approved for adult patients with relapsed or refractory Ph-ALL who have not responded or relapsed after two prior treatments. This indication received the FDA's accelerated approval based on tumor response rate. Clinical benefit such as improvement

in overall survival has not been verified. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

Currently, standard vincristine is not approved for the same indication as MARQIBO. However, there are many existing approaches used in the treatment of relapsed or refractory Ph-ALL, including combination chemotherapy and single agent regimens, which represent competition for MARQIBO. There are a variety of investigational agents in clinical trials for ALL that if approved could represent future competition for MARQIBO.

(e)
EVOMELA is a propylene glycol-free formulation. Given its unique formulation, there are no generic forms of EVOMELA on the market. However, there are currently several generic forms of melphalan used in the treatment of MM, which represent direct competition for EVOMELA. The current companies with forms of generic melphalan include Mylan, Teva Pharmaceutical Industries Ltd., Sagent Pharmaceuticals, PAR Pharmaceutical Dr. Reddy's Laboratories, and Fresenius Kabi Global.

(f) ROLONTIS (a)Eflapegrastim is a novel long-acting granulocyte colony-stimulating factorG-CSF that employs a proprietary technology that prolongs the duration of biologics, reducing the frequency of administration. There is currently one novel long-acting granulocyte colony stimulating factor (G-CSF)G-CSF and twofour biosimilar G-CSFs marketed in the United States including, Neulasta® (pegfilgrastim), marketed by Amgen, Inc., UDENYCA™ (pegfilgrastim-cbqv), a biosimilar marketed by Coherus BioSciences, and Fulphila® (pegfilgrastim-jmdb), a biosimilar marketed by Mylan Pharmaceuticals, Inc., and Ziextenzo® (pegfilgrastim-bmez), a biosimilar marketed by Sandoz, and NYVEPRIA™ (pegfilgrastim-apgf), a biosimilar marketed by Pfizer, Inc. In addition, there are several novel products in development that may compete with eflapegrastim if they are approved, including G1 Therapeutics’ trilaciclib, BeyondSpring’s plinabulin, and Evive Biotech’s benegrastim.


(g)
Poziotinib is a novel investigational, oral, quinazoline-based pan-HER inhibitor that irreversibly blocks signaling through the EGFR family of tyrosine-kinase receptors, including human epidermal growth factor receptor (HER1\ErbB1/EGFR), HER2 (ErbB2), and HER4 (ErbB4), as well as HER receptor mutations. Poziotinib’s development program is primarily focused on advanced NSCLC patients harboring exon 20 insertion mutations in both HER1/Erb1/EGFR and HER2(ErbB2). At present there are no FDA approved therapies for metastatic NSCLC patients with EGFR or HER2 exon 20 mutations expect for afatinib, which is FDA- approved for S768I point mutations.

New drug development is the process whereby drug product candidates are tested for the purpose of filing ana NDA or a BLA, in the U.S. (or similar filing in other countries). Obtaining marketing approval from the FDA or similar regulatory authorities outside of the U.S. is an inherently uncertain, lengthy, and expensive process that requires several phases of clinical trials to demonstrate to the satisfaction of the appropriate regulatory authorities that the products are both safe and effective for their respective indications. Our development focus is primarily based on acquiring and developing late-stage development drugs as compared to new drug discovery, which is particularly uncertain and lengthy.

Our in-development products are summarized below:

Patents and Proprietary Rights
Overview

Table of Contents


We in-license from third parties certain patentpatents and related intellectual property rights related to our proprietary drug products. Under most of these license arrangements, we are generally responsible for all development, patent filing, prosecution, and maintenance costs, sales, marketing and liability insurance costs related to the drug products.
In addition, these licenses and agreements may require us to make royalty and other payments and to reasonably utilize the underlying technology of applicable patents. If we fail to comply with these and other terms in these licenses and agreements, we could lose the underlying rights to one or more of our potential products, which would adversely affect our product development and harm our business. For more information regarding these arrangements see Note 17(b)7(b), "Financial“Financial Commitments & Contingencies and Key License Agreements," to our accompanying Consolidated Financial Statements.
The protection, preservation, and infringement-free commercial utilization of these patents and related intellectual property rights are very important to the successful execution of our strategy. However, the issuance of a patent is neither conclusive as to its validity nor as to the enforceable scope of the claims of the patent. Accordingly, our patents and the patents we have licensed may not prevent other companies from developing similar or functionally equivalent products or from successfully challenging the validity of our patents. If our patent applications are not allowed or, even if allowed and issued as patents, if such patents or the patents we have in-licensed are circumvented or not upheld by the courts,in a court of law or in administrative proceedings, including oppositions, re-examinations or inter parties review, our ability to competitively utilize our patented products and technologies may be significantly reduced. Also, such patents may or may not provide competitive advantages for their respective products or they may be challenged or circumvented by competitors, in which case our ability to commercially sell these products may be diminished.
From time-to-time, we may need to obtain licenses to patents and other proprietary rights held by third parties to develop, manufacture and market our products. If we are unable to timely obtain these licenses on commercially reasonable terms, our ability to commercially exploit such products may be inhibited or prevented.
Commercialized and In-Development Drug Products - Patents and Licenses Summary
We believe that our patents and licenses are critical to operating our business, as summarized below by commercialized and in-development drug products.below.
FUSILEVEflapegrastim: FUSILEV had orphan drug exclusivity for two indications. Marketing Composition of the product has been discontinued in the U.S. beginning in December 2018.
ZEVALIN: We have sublicensed U.S. patents that cover the processes and tools for making monoclonal anti-bodies or MABs, in general, licensed U.S. patents that cover the CD-20 MAB in ZEVALIN as well as the use of ZEVALIN to treat NHL, and acquiredmatter patents covering the ZEVALIN compounding process (i.e., process of linking the CD-20 MAB to a radioactive isotope to make the patient-ready dosage form of ZEVALIN). These patents expire over a wide range of dates, and the licensed patents covering the CD-20 MAB began to expire in 2015. Additionally, we have U.S. patents covering the compounding process expiring in 2019.
FOLOTYN: We have a composition of matter patenteflapegrastim are due to expire in November 2022, following2025 in the U.S. and in 2024 outside the U.S. We also have a five-yeareflapegrastim formulation patent granted in the U.S., Europe, Japan and other countries. The formulation patent will not expire in the U.S. until 2031. One of these patents is eligible for possible patent term extension in the U.S., as well as through confidential settlement agreements executed in June 2016 with five parties resulting from Paragraph IV certifications in connection with four separate ANDAs to manufacture a generic version of FOLOTYN. The composition of matter patent expired in Europe in 2017.
We also have patents covering the use of FOLOTYN for PTCL that will not expire until 2025. We have filed for extension of this patent in Japan where FOLOTYN was approved in 2017. If the extension is granted, the patent will be extended by approximately 3 years and 11 months. The use patent is eligible for similar patent term extension in Europe following regulatory approval.
BELEODAQ: The compositionapproval of mattereflapegrastim. Eflapegrastim is also covered by additional patents that cover BELEODAQ and related compounds do not begin to expire until 2021. We have applied for extensionpending applications claiming various aspects of the composition of matter patent in US. If an extension is granted, the patent will expire in 2026. In addition, there is atechnology and formulation patent which will not expire until 2027 in the U.S. Currently, there are multiple U.S. and foreign patent applications pending that cover BELEODAQ formulations, uses and manufacturing and synthesis processes.
We and Onxeo have filed a patent infringement lawsuit against Fresenius which triggered an automatic stay of this ANDA for 30 months, which will expire in April of 2021. The trial is currently scheduled to start in February of 2021. In addition, BELOEDAQ is protected from competition in the U.S. by an Orphan Drug Exclusivity indication until July 3, 2021.

MARQIBO: We have U.S. and European patents covering the use of MARQIBO for leukemia, lymphoma and melanoma, and a U.S. patent covering the MARQIBO kit, all expiring in 2020. We have filed a patent cooperation treaty, or PCT, application claiming a method of encapsulating vincristine sulphate into liposomes. We are presently in the process of developing a “single vial” formulation of MARQIBO and filed patent applications covering the formulation worldwide. If we are successful, we believe our patent coverage could be extended to 2036.
EVOMELA: This drug is covered by issued patents claiming improved Captisol® technology that are due to expire between 20252024 and 2034 in the U.S. Outside the U.S., we have issued patents that cover improved Captisol technology that are due to expire in 2025 and pending applications with anticipated expiry in 2029 (if issued). We also have filed patent applications covering the Captisol-based formulation2030.

Table of EVOMELA in the U.S. and a number of other countries.Contents
EVOMELA has orphan drug exclusivity for use as a high-dose conditioning treatment prior to hematopietic progenitor (stem) cell transplantation in patients with MM, which expires on March 10, 2023.
We obtained global development and commercialization rights to EVOMELA from Ligand Pharmaceuticals Incorporated, or Ligand, in March 2013. We thereafter assumed responsibility for completing its clinical trials and were responsible for filing the NDA. Under our license agreement with Ligand, Ligand received a license fee and is eligible to receive milestone payments and royalties. On December 20, 2017, CyDex Pharmaceuticals, Inc., a Ligand company, filed an action against Teva Pharmaceuticals USA, Inc., TEVA Pharmaceuticals Industries Ltd., and Actavis, LLC, together Teva, in the U.S. District Court for the District of Delaware, alleging patent infringement with respect to a paragraph IV certification, or an ANDA, filed with the FDA seeking approval to market a generic version of EVOMELA. Ligand brought suit against Teva to protect its intellectual property rights.
KHAPZORY: The U.S. patent application is currently underway, and depending its outcome, it may provide intellectual property protections for this product.
Poziotinib: A composition of matter patent covering poziotinib is due to expire in 2028. The patent is eligible for patent term extension following regulatory approval. Poziotinib is also covered by additional patents and patent applications covering its formulations and synthetic processes which will expire between 2032 and 2034. We are also considering filing of additionalhave licensed patent applications covering new formulations and uses.
QAPZOLA: The U.S. formulation patent for QAPZOLA does not expire until 2022, and a patent for the methoduse of treatment of bladder cancer using a stabilized formulation does not expire until 2024. Formulation patents outside the U.S. are due topoziotinib that if granted, would expire in 2022. We have filed additional U.S. and foreign patent applications covering new formulations and/or uses for this product.
ROLONTIS: Composition of matter patents covering ROLONTIS are due to expire in 2025 in the U.S. and in 2024 outside the U.S. We also have a ROLONTIS formulation patent granted in the U.S., Europe, Japan and other countries. The formulation patent will not expire until 2031. One of these patents is eligible for patent term extension following regulatory approval of ROLONTIS. ROLONTIS is also covered by additional patents and pending applications claiming various aspects of the technology that are due to expire between 2024 and 2030.2037.
Patent Protection and Value Maximization
We are constantly evaluating our patent portfolio and are currently assessing and filing patent applications for our drug products and considering new patent applications in order to maximize the life cycle of each of our products.
While the U.S. and the European Union, or EU, are currently the largest potential markets for most of our products, we also have patents issued and patent applications pending outside of the U.S. and Europe. Limitations on patent protection in these countries, and the differences in what constitutes patentable subject matter in countries outside the U.S., may limit the protection we have on patents issued or licensed to us outside of the U.S. In addition, laws of foreign countries may not protect our intellectual property to the same extent as would laws in the U.S.
To minimize our costs and expenses and to maintain effective protection, we usually focus our patent and licensing activities within the U.S., the EU, Canada, and Japan. In determining whether or not to seek a patent or to license any patent in a certain foreign country, we weigh the relevant costs and benefits, and consider, among other things, the market potential and profitability, the scope of patent protection afforded by the law of the jurisdiction and its enforceability, and the nature of terms with any potential licensees. Failure to obtain adequate patent protection for our proprietary drugs and technology would impair our ability to be commercially competitive in these markets.

In conducting our business, we rely upon trade secrets, know-how, and licensing arrangements. We use customary practices for the protection of our confidential and proprietary information such as confidentiality agreements and trade secret protection measures. It is possible that these agreements will be breached or will not be enforceable in every instance, and that we will not have adequate remedies for any such breach. It is also possible that our trade secrets or know-how will otherwise become known or independently developed by competitors. The protection of know-how is particularly important because it is often necessary or useful information that allows us to practice the claims in the patents related to our proprietary drug products.
In addition to the specific intellectual property subjects discussed above, we have a trademark registrationsregistration in the U.S. for Spectrum Pharmaceuticals, Inc.®, FUSILEV®, FOLOTYN®, ZEVALIN®, MARQIBO®, BELEODAQ®, EVOMELA®, and ROLONTIS®. We also have trademarks in KHAPZORY™, REDEFINING CANCER CARE™, andfor the Spectrum Pharmaceuticals'Pharmaceuticals’ logos. Any other trademarks are the property of their respective owners.

The Patent Process
The U.S. Constitution provides Congress with the authority to provide inventors the exclusive right to their discoveries. Congress codified this right in U.S. Code Title 35, which gave the United States Patent and Trademark Office, or USPTO, the right to grant patents to inventors and defined the process for securing a U.S. patent. This process involves the filing of a patent application that instructs a person having ordinary skill in the respective art how to make and use the invention in clear and concise terms. The invention must be novel (i.e., not previously known) and non-obvious (i.e., not an obvious extension of what is already known). The patent application concludes with a series of claims that specifically describe the subject matter that the patent applicant considers his invention.
The USPTO undertakes an examination process that can take from one to seven years, or more, depending on the complexity of the patent and the problems encountered during examination.
In exchange for disclosing the invention to the public, for all U.S. patent applications filed after 1995, the successful patent applicant is currently provided a right to exclude others from making, using or selling the claimed invention for a period of 20 years from the effective filing date of the patent application.
Under certain circumstances, a patent term may be extended. Patent extensions are most frequently granted in the pharmaceutical and medical device industries under the Drug Price Competition and Patent Term Restoration Act of 1984, or the Hatch-Waxman Act, to recover some of the time lost during the FDA regulatory process, subject to a number of limitations and exceptions. The patent term may be extended up to a maximum of five years, but cannot be extended beyond a total of 14 years from the date of the product's approval; however, as a general rule, the average extension period granted for a new drug is approximately three years. Only one patent can be extended per FDA approved product, and a patent can only be extended once.
Product Exclusivity
Under the Hatch-Waxman Act, drug products are provided exclusivity whereby the FDA will not approve applications to market a generic form of an innovator reference listed drug product until the end of the prescribed period. A product is granted a five-year period of exclusivity if it contains a chemical entity never previously approved by the FDA either alone or in combination, although generic applications may be submitted after four years if they contain a certification of patent invalidity or non-infringement as further discussed below. A three-year period of exclusivity is granted to a previously approved product based on certain changes (e.g., in strength, dosage form, route of administration or conditions of use), where the application is supported by new clinical investigations that are essential to approval. In addition, in 1997, Congress amended the law to provide an additional six months of exclusivity as a reward for studying drugs in children. This pediatric exclusivity, which can be obtained during the approval process or after approval, effectively prevents the FDA from approving a generic application until six months after the expiration of any patent. In order to qualify for pediatric exclusivity, the FDA must make a written request for pediatric studies, the application holder must agree to the request and complete the studies within the required timeframe, and the studies must be accepted by the FDA based on a determination that the studies fairly respond to the request.
Generic Approval andThe Patent Certification
The Hatch-Waxman Act also created the ANDA approval process, which permits the approval of a generic version of a previously approved branded drug without the submission of a full NDA, and based in part on the FDA’s finding of safety and effectiveness for the reference listed drug. Applicants submitting an NDA are required to list patents associated with the drug product, which are published in the FDA Orange Book, and the timing of an ANDA approval depends in part on patent

Table of Contents


protection for the branded drug. When an ANDA is filed, the applicant must file a certification for each of the listed patents for the branded drug, stating one of the following: (1) that there is no patent information listed; (2) that such patent has expired; (3) that the patent will expire on a particular date (indicating that the ANDA may be approved on that date); or (4) that the drug for which approval is sought either does not infringe the patent or the patent is unenforceable or invalid, otherwise known as paragraph IV certification. If an ANDA applicant files a paragraph IV certification, it is required to provide the patent holder with notice of that certification. If the patent holder brings suit against the ANDA applicant for patent infringement within 45 days of receiving notice, generally the FDA may not approve the ANDA until the earlier of (i) 30 months from the patent holder’s receipt of the notice (the 30-month stay) or (ii) the issuance of a final, non-appealed, or non-appealable court decision finding the patent invalid, unenforceable or not infringed.

The Hatch-Waxman Act also provided an incentive for generic manufacturers to file paragraph IV certifications challenging patents that may be invalid, unenforceable, or not infringed, whereby the first company to successfully challenge a listed patent and receive ANDA approval is protected from competition from subsequent generic versions of the same drug product for up to 180 days after the earlier of (1) the date of the first commercial marketing of the first-filed ANDA applicant’s generic drug or (2) the date of a decision of a court in an action holding the relevant patent invalid, unenforceable, or not infringed. These 180-day exclusivity provisions have been the subject of litigation and administrative review, and the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, or MMA, amended the provisions in several ways, including by providing that an ANDA applicant entitled to 180-day exclusivity may lose such exclusivity if any of the following events occur: (1) failure to market; (2) withdrawal of the ANDA; (3) change in patent certification; (4) failure to obtain tentative approval; (5) illegal settlement agreement; or (6) patent expiration.
With respect to the illegal settlement prong, the MMA amendments require that certain types of settlement agreements entered into between branded and generic pharmaceutical companies related to the manufacture, marketing and sale of generic versions of branded drugs are required to be filed with the Federal Trade Commission and the Department of Justice for review of potential anti-competitive practices. This requirement could affect the manner in which generic drug manufacturers resolve intellectual property litigation and other disputes with branded pharmaceutical companies, and could result generally in an increase in private-party litigation against pharmaceutical companies. The impact of this requirement, and the potential governmental investigations and private-party lawsuits associated with arrangements between brand name and generic drug manufacturers, remains uncertain. In addition, Congress has considered enacting legislation that would prohibit such settlements between brand name and generic drug manufacturers. Such a provision was considered as part of the Patient Protection and Affordable Care Act, or PPACA, signed into law on March 23, 2010. However, Congress removedas amended by the provision prior to passage. It is possible that Congress will again consider a ban on such settlements between brand nameHealth Care and generic drug manufacturers in the future.
The PPACAEducation Reconciliation Act of 2010 (“PPACA”), provides exclusivity protections for certain innovator biological products and a framework for FDA review and approval of biosimilar and interchangeable versions of innovator biologic products. The PPACA provides that no application for a biosimilar product may be approved until 12 years after the date on which the innovator product was first licensed, and no application may be submitted until four years after the date of the first licensure. Products deemed interchangeable (as opposed to biosimilar) are also eligible for certain exclusivity.
Orphan Drug Designation
Some jurisdictions, including Europe and the U.S., may designate drugs for relatively small patient populations as “orphan” drugs. The FDA may grant orphan drug designation to a drug intended to treat a rare disease or condition that affects fewer than 200,000 individuals in the U.S., and a drug may also be considered an orphan even if the drug treats a disease or condition affecting more than 200,000 individuals in the U.S. Orphan drug designation does not necessarily convey any advantage in, or shorten the duration of, the regulatory review and process for marketing approval. If a product with an orphan drug designation subsequently receives the first FDA approval for the indication for which it has such designation, the product is entitled to seven years of orphan drug exclusivity, during which time the FDA will not approve any other application to market the same drug for the same indication except in limited circumstances, such as a showing of clinical superiority to the product with orphan exclusivity. Also, competitors are not prohibited from receiving approval to market the same drug or biologic for a different indication than that which received orphan approval.
Under EU medicines laws, the criteria for designating an “orphan medicinal product” are similar in principle to those in the U.S. Criteria for orphan designation are set out in Article 3 of Regulation (EC) 141/2000 on the basis of two alternative conditions. A medicinal product may be designated as orphan if it is intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition affecting not more than five in 10,000 persons in the EU, when the application is made. This is commonly known as the “disease prevalence criterion,” Alternatively, a product may be so designated if it is intended for the diagnosis, prevention or treatment of a life-threatening, seriously debilitating or serious and

16

Table of Contents


chronic condition in the EU and if, without incentives, it is unlikely that the marketing of the product in the EU would generate sufficient return to justify the necessary investment. This is commonly known as the “insufficient return criterion.”

These two alternative criteria must cumulatively meet the second condition that there exists no satisfactory method of diagnosis, prevention or treatment of the condition in question that has been authorized in the EU, or if such a method exists, the product will be of significant benefit to those affected by the condition. “Significant benefit” is defined in Regulation (EC) 847/2000 as a clinically relevant advantage or a major contribution to patient care.
Upon grant of a marketing authorization, orphan medicinal products are entitled to ten years of market exclusivity in respect of the approved therapeutic indication. Within the period of market exclusivity, no competent authority in the EU is permitted to accept an application for marketing authorization, a variation or a line-extension for the same approved therapeutic indication in respect of a similar medicinal product pursuant to Article 8.1 of Regulation (EC) 141/2000 unless one of the derogations set out in Article 8.3 of the same Regulation applies. In order to determine whether two products are considered similar, Regulation (EC) 847/2000 requires an assessment of the principal molecular structure and the underlying mode of action. Any minor variation or modification of the principal molecular structure would not ordinarily render the second product dissimilar to the first authorized product.
In order for the second applicant to break the market exclusivity granted to the first authorized similar medicinal product in respect of the same therapeutic indication, the second applicant would principally rely upon data to demonstrate that its product is safer, more efficacious or clinically superior to the first product pursuant to Article 8.3(i) of Regulation (EC) 141/2000. Ordinarily, such an assessment will require a head-to-head comparative clinical trial for the purpose of demonstrating clinical superiority.
The 10-year market exclusivity may be reduced to six years if at the end of the fifth year it is established that the product no longer meets the criteria for orphan designation on the basis of available evidence. We have in the past received, and currently hold, orphan drug designations for some of our products.
    Currently, BELEODAQ has orphan drug designation for use in PTCL, and EVOMELA has orphan drug designation as a high-dose conditioning treatment prior to hematopoietic progenitor (stem) cell transplantation in patients with MM. In addition, MARQIBO has orphan drug designations for its use in the treatment of adult patients with ALL in second or greater relapse or whose disease has progressed following two or more anti-leukemia therapies, and ZEVALIN has orphan drug designations for the treatment of patients with relapsed or refractory low-grade, follicular, or transformed B-cell NHL, including patients with Rituximab refractory follicular NHL.
Governmental Regulation
The development, production and marketing of our proprietary and biologic products are subject to regulation for safety, efficacy and quality by numerous governmental authorities in the U.S. and other countries. In the U.S., drugs and biologics are subject to rigorous regulation. The Federal Food, Drug, and Cosmetic Act, as amended from time to time, and the regulations promulgated thereunder, as well as other federal and state statutes and regulations, govern, among other things, the development, approval, manufacture, safety, labeling, storage, record keeping, distribution, promotion, and advertising of our products. Product development and approval within this regulatory framework, including for drugs already at a clinical stage of development, can take many years and require the expenditure of substantial resources, and to obtain FDA approval, a product must satisfy mandatory quality, safety, and efficacy requirements. In addition, each drug-manufacturing establishment must be registered with the FDA. Domestic manufacturing establishments must comply with the FDA’s current Good Manufacturing Practices, or cGMP, regulations and are subject to inspections by the FDA. To supply drug ingredients or products for use in the U.S., foreign manufacturing establishments must also comply with cGMP and are subject to inspections by the FDA or by other regulatory authorities in certain countries under reciprocal agreements with the FDA.
General Information about the Drug Approval Process and Post-Marketing Requirements

Table of Contents

The U.S. system of new drug and biologics approval is a rigorous process. Only a small percentage of compounds that enter the pre-clinical testing stage are ever approved for commercialization. Our strategy focuses on in-licensing clinical stage drug products that are already in or about to enter human clinical trials. A late-stage focus helps us to effectively manage the high cost of drug development by focusing on compounds that have already passed the many hurdles in the pre-clinical and early clinical process.

The following general comments about the drug approval process are relevant to the development activities we are undertaking with our proprietary products.

17

Table of Contents


Pre-clinical Testing: During the pre-clinical testing stage, laboratory and animal studies are conducted to show biological activity of a drug or biologic compound against the targeted disease. The compound is evaluated for safety. While some of our compounds are currently in clinical trials, it is possible that additional pre-clinical testing could be requested by a regulatory authority for any of our compounds.
Investigational New Drug Application:Application (“IND”): After certain pre-clinical studies are completed, an IND application is submitted to the FDA to request the ability to begin human testing of the drug or biologic. An IND becomes effective thirty days after the FDA receives the application (unless the FDA notifies the sponsor of a clinical hold), or upon prior notification by the FDA.
Phase 1 Clinical Trials: These trials typically involve small numbers of healthy volunteers or patients and usually define a drug candidate’s safety profile, including the safe dosage range.
Phase 2 Clinical Trials: In Phase 2 clinical trials, controlled studies of human patients with the targeted disease are conducted to assess the drug’s effectiveness. These studies are designed primarily to determine the appropriate dose levels, dose schedules and route(s) of administration, and to evaluate the effectiveness of the drug or biologic on humans, as well as to determine if there are any side effects on humans to expand the safety profile following Phase 1. These clinical trials, and Phase 3 trials discussed below, are designed to evaluate the product’s overall benefit-risk profile, and to provide information for physician labeling.
Phase 3 Clinical Trials: This Phase usually involves a larger number of patients with the targeted disease. Investigators (typically physicians) monitor the patients to determine the drug candidate’s efficacy and to observe and report any adverse reactions that may result from long-term use of the drug on a large, more widespread, patient population. During the Phase 3 clinical trials, typically the drug candidate is compared to either a placebo or a standard treatment for the target disease.
New Drug Application or Biologics License Application: After completion of all three clinical trial Phases, if the data indicates that the drug is safe and effective, ana NDA or BLA is filed with the FDA requesting FDA approval to market the new drug as a treatment for the target disease.
Fast Track and Priority Review: The FDA has established procedures for accelerating the approval of drugs to be marketed for serious or life-threatening diseases for which the manufacturer can demonstrate the potential to address unmet medical needs. As discussed above, we have obtained accelerated approval to market FOLOTYN, BELEODAQ and
MARQIBO.
Abbreviated New Drug Application:Application (“ANDA”): An ANDA is an abbreviated new drug application for generic drugs created by the Hatch-Waxman Act. When a company files an ANDA, it must make a patent certification regarding the patents covering the branded product listed in the FDA’s Orange Book. The ANDA drug development process generally takes less time than the NDA drug development process since the ANDA process usually does not require new clinical trials establishing the safety and efficacy of the drug product.
Breakthrough Therapy Designation:Designation (“BTD”): A BTD is available from the FDA for drugs or drug combinations used to treat serious or life-threatening disease conditions based on preliminary clinical evidence that the drug may offer substantial improvement over existing therapies. FDA may grant priority approval to breakthrough drug indications. FDA may also grant accelerated approval and priority review for drugs that fill an unmet medical need. An advantage to this designation is that clinical trials may use surrogate endpoints to predict clinical benefit, requiring less time than other objective endpoints such as overall survival.
NDA/BLA and ANDA Approval: The FDA approves drugs and biologics that are subject to NDA and BLA review based on data in the application demonstrating the product is safe and effective in its proposed use(s) and that the product’s benefits outweigh its risks. The FDA will also review the NDA or BLA applicant’s manufacturing process and controls to ensure they are adequate to preserve the drug’s identity, strength, quality, and purity. Finally, the FDA will review and approve the

Table of Contents

product’s proposed labeling. As for the ANDA approval process, these “abbreviated” applications are generally not required to include pre-clinical or clinical data to establish safety and effectiveness. Rather, an ANDA must demonstrate both chemical equivalence and bio-equivalence (the rate and extent of absorption in the body) to the innovator drug — unless a bio-equivalence waiver is granted by the FDA.
Postmarketing requirements (PMRs): PMR refers to postmarketing requirements, studies or clinical trials the sponsor is required to conduct. These studies might be required for a number of reasons including:
Postmarketing studies or clinical trials to demonstrate clinical benefit for drugs approved under the accelerated approval requirements
Deferred pediatric studies, where studies are required under the Pediatric Research Equity Act (PREA)
Studies or clinical trials to demonstrate safety and efficacy in humans that must be conducted at the time of use of products approved under the Animal Efficacy Rule
Phase 4 Clinical Trials: After a drug has been approved by the FDA, Phase 4 studies may be conducted to explore additional patient populations, compare the drug to a competitor, or to further study the risks, benefits and optimal use of a drug. These studies may be a requirement as a condition of the initial approval of the NDA or BLA.

Post-Approval Studies Requirements under FDAAA: The Food and Drug Administration Amendments Act of 2007, or FDAAA, significantly added to the FDA’s authority to require post-approval studies. Under the FDAAA, if the FDA becomes aware of new safety information after approval of a product, they may require us to conduct further clinical trials to assess a known serious risk, signals of serious risk or to identify an unexpected serious risk. If required to conduct a post-approval study, periodic status reports must be submitted to the FDA. Failure to conduct such post-approval studies in a timely manner may result in administrative action being taken by FDA, including substantial civil fines.
Risk Evaluation and Mitigation Strategy Authority under FDAAA: The FDAAA also gave the FDA authority to require the implementation of a Risk Evaluation and Mitigation Strategy, or REMS, for a product when necessary to minimize known and preventable safety risks associated with the product. The FDA may require the submission of a REMS before a product is approved, or after approval based on “new safety information,” including new analysis of existing safety information. A REMS may include a medication guide, patient package insert, a plan for communication with healthcare providers, or other elements as the FDA deems are necessary to assure safe use of the product, which could include imposing certain restrictions on distribution or use of a product. A REMS must include a timetable for submission of assessments of the strategy at specified time intervals. Failure to comply with a REMS, including the submission of a required assessment, may result in substantial civil or criminal penalties.

Other Issues Related to Product Safety: Adverse events that are reported after marketing approval also can result in additional limitations being placed on a product’s use and, potentially, withdrawal of the product from the market. In addition, under the FDAAA, the FDA has authority to mandate labeling changes to products at any point in a product’s life cycle based on new safety information derived from clinical trials, post-approval studies, peer-reviewed medical literature, or post-market risk identification and analysis systems data.
FDA Enforcement
The development of drug and biologic products, as well as the marketing of approved drugs and biologics, is subject to substantial continuing regulation by the FDA, including regulation of adverse event reporting, manufacturing practices and the advertising and promotion of the product. Failure to comply with the FDA and other governmental regulations can result in fines, unanticipated compliance expenditures, recall or seizure of products, total or partial suspension of production and/or distribution, suspension of the FDA’s review of NDAs, BLAs, ANDAs or other product applications, enforcement actions, injunctions and criminal prosecution. Under certain circumstances, the FDA also has the authority to revoke previously granted drug approvals.
With respect specifically to information submitted to the FDA in support of marketing applications, the FDA, under its Fraud, Untrue Statements of Material Facts, Bribery and Illegal Gratuities Policy, can significantly delay the approval of a marketing application, or seek to withdraw an approved application where it identifies fraud or discrepancies in regulatory submissions. Such actions by the FDA may significantly delay or suspend substantive scientific review of a pending application during validity assessment or remove approved products from the market until the assessment is complete and questions regarding reliability of the data are resolved. In addition, the Generic Drug Enforcement Act of 1992 (the “Generic Drug Enforcement Act”) established penalties for wrongdoing in connection with the development or submission of an ANDA. Under thisthe Generic Drug Enforcement Act, the FDA has the authority to permanently or temporarily bar companies or
10

Table of Contents

individuals from submitting or assisting in the submission of an ANDA, and to temporarily deny approval and suspend applications to market generic drugs. The FDA may also suspend the distribution of all drugs approved or developed in connection with certain wrongful conduct and/or withdraw approval of an ANDA and seek civil penalties.
Healthcare Reform
Continuing studies of the proper utilization, safety and efficacy of pharmaceuticals and other health care products are being conducted by industry, government agencies and others. Such studies, which increasingly employ sophisticated methods and techniques, can call into question the utilization, safety and efficacy of previously marketed products and in some cases have resulted, and may in the future result, in the discontinuance of their marketing.
The Patient Centered Outcomes Research Institute, or the Institute, a private, non-profit corporation created as a result of the PPACA, is tasked with assisting patients, clinicians, purchasers, and policy-makers in making informed health decisions. One of the Institute’s initiatives will be to conduct comparative clinical effectiveness research, which is defined as “research evaluating and comparing health outcomes and the clinical effectiveness, risks, and benefits of two or more medical treatments, services, and items.” It is important to note that the Institute would not be permitted to mandate coverage, reimbursement, or other policies for any public or private payer, however, the outcome of the Institute'sInstitute’s initiatives could influence prescriber behavior.

Foreign Regulation
Whether or not we obtain FDA approval for a product, we must obtain approval of a product by the comparable regulatory authorities of foreign countries before we can commence clinical trials or marketing of the product in those countries. The approval process varies from country/region to country/region, and the time may be longer or shorter than that required for FDA approval. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement also may vary, sometimes significantly, from country/region to country/region.

Under the EU regulatory systems, we may submit marketing authorization applications either under a centralized procedure or decentralized procedure or the mutual recognition procedure. The centralized procedure is mandatory for medicines produced by a biotechnological process. The procedure is also mandatory for new active substances which are indicated for treatment of several diseases or conditions, including cancer and orphan conditions. Companies may apply for centralized assessment if the product contains a new active substance or the product constitutes significant therapeutic, scientific or technical innovation or the granting of authorization under the centralized procedure is in the interests of the EU patients. A centralized marketing authorization is valid in all EU member states. This marketing authorization is issued in the form of a European Commission decision which is legally binding in its entirety to which it is addressed.
Directive 2004/27/EC introduced two parallel procedures to the centralized procedure to allow a product to be progressively authorized in each of the member states of the EU. They are the decentralized procedure and the mutual recognition procedure. The mutual recognition procedure applies where the product has already been authorized in a member state of the EU that will act as reference member state. The national marketing authorization granted by the reference member state forms the basis for mutual recognition in the member states chosen by the applicant. In the decentralized procedure, the product in question is not authorized in any one the EU member states. In such a situation, the applicant company will request a member state to act as the reference member state to lead the scientific assessment for the benefit/risk balance for agreement by the concerned member states. In both cases, the concerned member states have up to 90 days to accept or raise reasoned objections to the assessment made by the reference member state.
In addition, pricing and reimbursement is subject to negotiation and regulation in most countries outside the U.S. Increasingly, adoption of a new product for use in national health services is subject to health technology assessment under the national rules and regulations to establish the clinical effectiveness and cost-effectiveness of a new treatment. In some countries, in order to contain health care expenditures, reference price is introduced in order for the national healthcare providers to achieve a price comparable to the reference price in the same therapeutic category. We may therefore face the risk that the resulting prices would be insufficient to generate an acceptable return to us.
Third Party Reimbursement and Pricing Controls
In the U.S. and elsewhere, sales of pharmaceutical products depend in significant part on the availability of reimbursement to the consumer from third-party payers, such as government and private insurance plans. Third-party payers are increasingly challenging the prices charged for medical products and services. It is time-consuming and expensive for us to go
11

Table of Contents

through the process of seeking coverage from Medicare and private payers. Our products may not be considered cost effective, and coverage and reimbursement may not be available or sufficient to allow us to sell our products on a competitive and profitable basis.
The PPACA enacted significant reforms, including revising the definition of “average manufacturer price” for reporting purposes, increasing Medicaid rebates, expanding the 340B drug discount program, and making changes to affect the Medicare Part D coverage gap, or “donut hole.” In the coming years, additional significant changes could be made to governmental healthcare programs, and to the U.S. healthcare system as a whole, that may result in significantly increased demand for rebates, decreased pricing flexibility, diminished negotiating flexibility, coverage and reimbursement limitations based upon comparative and cost-effectiveness reviews, and other measures that could significantly impact the success of our products.
In many foreign markets, including the countries in the EU, pricing of pharmaceutical products is subject to governmental control. In the U.S., there have been, and we expect that there will continue to be, a number of federal and state proposals to implement similar governmental pricing controls or product coverage limitations.
Employees
As of December 31, 2018,2021, we had 235164 employees (as compared to 215176 employees as of December 31, 2017)2020), 8163 of whom were full-time employees, 7 of whom hold an M.D. degree and 1729 of whom hold a Ph.D. degree.

Implemented safety procedures for all staff, which includes on site and essential travel training for those applicable employees;
Provided full coverage for all COVID related medical expenses for all eligible employees and their family members, and paid time off for any employee that missed time due to the COVID-19 pandemic including for the care of family members; and
Modified our flexible spending and 401(k) plans to allow employees more financial flexibility during the economic downturn resulting from the pandemic.
We provide competitive compensation packages designed to attract and retain high-quality employees. All of our employees are eligible for cash bonuses and grants of equity awards. We regularly evaluate our compensation programs with an independent compensation consultant and utilize industry benchmarking in an effort to ensure competitiveness compared to similar biotechnology and biopharmaceutical companies with which we compete for talent, as well as fair and equitable across our workforce with respect to gender, race, and other personal characteristics. In addition, we provide a variety of programs and services to help employees balance their career and home life, including an attractive mix of healthcare, insurance, and other benefit plans. We deliver a benefits program that is designed to keep our employees and their families healthy, which includes not only medical, dental and vision benefits, but also legal services, supplemental life insurance, pet insurance, paid parental leave, dependent care, mental health services, company sponsored fitness programs, and other wellness benefits and incentives.
We also value career development for all employees, and we provide reimbursement and time for employees to attend professional development courses ranging from technical training, competency-based workshops and leadership development programs facilitated by external partners who are experts in their respective fields. Direct managers also take an active role in

Risks Related to Our Business

If we are unable to continue to successfully develop poziotinib, eflapegrastim, or any of our other pipeline products, our business, prospects, operating results, and financial condition will be materially harmed.
Clinical trials may fail to demonstrate the safety and efficacy of our drug products, which could prevent or significantly delay obtaining regulatory approval.
We currently generate no revenue from commercial sales and future commercial sales may not be sufficient to sustain our business operations.

The COVID-19 pandemic and any similar future outbreaks could materially and adversely impact or disrupt our business and our financial condition, results of operations, cash flows and performance.
The pharmaceutical and biotechnology industries are intensely competitive. We are aware of several competitors attempting to develop and market products competitive to our in-development products, which may reduce or eliminate our commercial opportunities in the future.
Our supply of APIs, and drug products is and will remain dependent upon the production capabilities of contract manufacturing organizations (“CMOs”) and other third-parties for related supplies and logistical services. Some of these vendors are based overseas.If our CMOs and other suppliers are not able to meet our requirements or FDA scrutiny, we may be unable to obtain approval for our products. Even if we do obtain approval for our products, we may be limited in our ability to meet demand for our products, ensure regulatory compliance, or maximize profit on the future sale of our products. Any manufacturing-related disruptions could create significant demand on our limited capital resources, and there can be no assurance that we would be able to continue as a going concern. In addition, our dependence on these ex-U.S. vendors also subjects us to business interruption risks related to COVID-19, and/or similar outbreaks, which could have a material adverse impact on us.
Our future sales will depend on coverage and reimbursement from third-party payers and a reduction in the coverage and/or reimbursement for our products could have a material adverse effect on our product sales, business and results of operations.
SalesA breakdown or breach of our information technology systems and cybersecurity efforts could subject us to liability, reputational damage or interrupt the operation of our business.
Reports of adverse events or safety concerns involving our in-development products or similar agents, could delay or prevent us from obtaining or maintaining regulatory approval or negatively impact sales.
Our dependence on key executives, scientists and sales and marketing personnel could impact the development and management of our business.
Competition for patients in conducting clinical trials may prevent or delay product development and strain our limited financial resources.
Risks Related to Our Industry
If we are dependent onunable to obtain regulatory approval for our product candidates, or if we fail to comply with governmental regulations, we will be limited in our ability to commercialize our products and product candidates domestically or abroad and/or will be subject to penalties.
Even after we receive regulatory approval to market our drug products, the availabilitymarket may not be receptive to our drug products upon their commercial introduction, which would negatively impact our ability to achieve profitability.
Guidelines and extentrecommendations from various organizations can reduce the use of our products.
Legislative or regulatory reform of the healthcare system and pharmaceutical industry related to pricing, coverage or reimbursement may hurt our ability to sell our products profitably or at all.
If our marketing violates federal or state health care fraud and abuse laws, we may be subject to civil or criminal penalties, including exclusion from participation in government health care programs.
We could be adversely affected by violations of the FCPA and other worldwide anti-bribery laws.
Governmental pricing regulations could adversely affect our negotiated pricing, or limit product coverage and reimbursement,reimbursements may adversely impact our operating results and our business.
Risks Related to Our Common Stock
Future issuances of our common stock or levelother dilutive instruments, may materially and adversely affect the price of reimbursement, from third-party payers, including government programsour common stock and private insurance plans. Governments and private payers may regulate prices, reimbursement levels and/or accesscause dilution to our products to contain costs or to affect levels of use. We rely in large part on the reimbursementexisting stockholders.
The market price and trading volume of our products through government programs such as Medicarecommon stock fluctuate significantly and Medicaidcould result in substantial losses for individual investors.
If our common stock continues to trade below $1, our stock could be delisted.
Provisions of our charter, and bylaws may make it more difficult for someone to acquire control of us or replace current management even if doing so would benefit our stockholders, which may lower the price an acquirer or investor would pay for our stock.
Risks Relating to Our Intellectual Property

In-license patents and proprietary technologies from third parties may be difficult or expensive to obtain.
If we are unable to adequately protect our technology or enforce our patent rights, our business could suffer, and intellectual property rights don’t necessarily address all potential threats.
If we fail to comply with our obligations in the U.S., and a reduction in the coverage and/agreements under which we license intellectual property rights from third parties or reimbursement forotherwise experience disruptions to our productsbusiness relationships with our licensors, we could lose intellectual property rights that are important to our business.

Mostcosts of maintaining our patents can be costly, complex, and uncertain and we may be subject to infringement claims.
We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed confidential information of third parties or that our employees have wrongfully used or disclosed alleged trade secrets of their former employers.
We may be involved in additional lawsuits to defend or enforce our patents, which could be expensive, time-consuming and unsuccessful.
We may be subject to claims challenging the inventorship of our products furnishedpatents and other intellectual property, and may be subject to Medicare beneficiariesfederal regulations such as “march-in” rights that limit our exclusive rights or ability to contract with non-US manufacturers.
General Risk Factors
Lack of effective internal controls over financial reporting could result in both a physician office setting and hospital outpatient setting are reimbursed undermaterial misstatements that affects investor confidence negatively, which in turn could cause the Medicare Part B Average Sales Price, or ASP, payment methodology. ASP-based reimbursementtrading price of our products under Medicare may be belowcommon stock to decline.
Earthquakes or other natural or man-made disasters and business interruptions could fall below the cost that some medical providers pay for such products, which could materially and adversely affect salesour business.
We are subject to the risks of securities and related litigation, which may expose us to substantial liabilities and could seriously harm our business.
Global, market and economic conditions may negatively impact our business, financial condition and share price.
For a more complete discussion of the material risks facing our business, see below.
Risks Related to Our Business
If we are unable to continue to successfully develop poziotinib, eflapegrastim, or any of our products. We also face risks relatingother pipeline products, our business, prospects, operating results, and financial condition will be materially harmed.
The announcement of any negative or unexpected data, any delay in our anticipated timelines for filing for regulatory approval, or a significant advancement of a competitor, may cause our stock price to the reporting of pricing data that affect the U.S. reimbursement ofdecline significantly and discounts for our products. ASP data are calculated by the manufacturer

based on a formula defined by statute and regulation and are then submitted to the Centers for Medicare & Medicaid Services, or CMS, the agency responsible for administering the Medicare program, on a quarterly basis.
CMS uses those ASP data to determine the applicable reimbursement rates for our products under Medicare Part B. However, the statute, regulations and CMS guidance do not define specific methodologies for all aspects of the reporting of ASP data. For example, CMS has not provided specific guidance regarding administrative fees paid to GPOs in the ASP calculation. CMS directs that manufacturers make “reasonable assumptions” in their calculation of ASP data in the absence of specific CMS guidance on a topic. As a result, we are required to apply our reasonable judgment to certain aspects of calculating ASP data. If our submitted ASP data are incorrect, we may become subject to substantial fines and penalties or other government enforcement actions, which could have a materialan adverse impact on our business, financial condition and prospects. In addition, clinical trial results are frequently susceptible to varying interpretations that may delay, limit or prevent regulatory approvals. There is no assurance that data from our clinical trials will support filings for regulatory approval of any of our pipeline products, or even if approved, that these drugs will become commercially successful for all approved indications. In addition, we may experience significant setbacks in our advanced clinical trials, even after promising results in earlier trials, including unexpected adverse events. Any deficiencies in the our clinical trial operations or other unexpected adverse events impacting such trials could cause increased costs, program delays or both, which may harm our business.
If one of our pipeline products fails at any stage of development, or we otherwise determine to discontinue development of that product, we will not have the anticipated revenues from that product, and we may not receive any return of our investment on it. Consequently, our stock price could decline significantly and there could be an adverse impact on our business, financial condition, results of operations.operations and prospects.

For example, in October of 2019 we announced that we had submitted the BLA for eflapegrastim and in August 2021, we received a Complete Response Letter from the FDA regarding our BLA, citing deficiencies related to manufacturing and indicating that a reinspection will be necessary. We believe we have completed the remediation of these deficiencies and resubmitted the BLA on March 11, 2022. In addition, the company announced the submission of the poziotinib NDA in December 2021. In February of 2022, the company announced that the FDA accepted the NDA and reiterated the importance of having the confirmatory trial substantially enrolled at the time of approval and requested additional information around dosing. Due to the uncertainty of the regulatory approval process, we may not be successful at developing these drugs or receiving approval.
Clinical trials may fail to demonstrate the safety and efficacy of our drug products, which could prevent or significantly delay obtaining regulatory approval.
Prior to receiving approval to commercialize any of our drug products, we must demonstrate with substantial evidence from well-controlled clinical trials, and to the satisfaction of the FDA, and other regulatory authorities in the U.S. and other countries, that each of the products is both safe and effective. For each drug product, we will need to demonstrate its efficacy and monitor its safety throughout the process. If such development is unsuccessful, our business and reputation would be harmed and our stock price would be adversely affected.
We are currently conducting multiple clinical trials for our products. Each of our clinical trials requires investment of substantial financial and personnel resources. The commencement and completion of these clinical trials may be delayed by various factors, including scheduling conflicts with participating clinicians and clinical institutions, difficulties in identifying and enrolling patients who meet trial eligibility criteria, failure of patients to complete the clinical trial, delays in accumulating the required number of clinical events for data analysis, delay or failure to obtain the required approval to conduct a clinical trial at a prospective site, and shortages of available drug supply.
All of our drug products are prone to the risks of failure inherent in drug development. Clinical trials of new drug products sufficient to obtain regulatory marketing approval are expensive, uncertain, and take years to complete. We may not be able to successfully complete clinical testing within the time frame we have planned, or at all. Moreover, the outcome of a clinical trial is often uncertain. We may experience numerous unforeseen events during, or as a result of, the clinical trial process that could delay or prevent us from receiving regulatory approval or commercializing our drug products. In this regard, reports of adverse events or concerns involving any of our products could interrupt, delay or halt clinical trials of such products or could result in our inability to obtain regulatory approvals for such products. In addition, the results of pre-clinical studies and early-stage clinical trials of our drug products do not necessarily predict the results of later-stage clinical trials. Later-stage clinical trials may fail to demonstrate that a drug product is safe and effective despite having progressed through initial clinical testing. Even if we believe the data collected from clinical trials of our drug products is promising, data are susceptible to varying interpretations, and such data may not be sufficient to support approval by the FDA or any other U.S. or foreign regulatory approval. Pre-clinical and clinical data can be interpreted in different ways.
Accordingly, FDA officials could interpret such data in different ways than we or our partners do which could delay, limit or prevent regulatory approval. The FDA, other regulatory authorities, our institutional review boards, our contract research organizations, or we may suspend or terminate our clinical trials for our drug products. Any failure or significant delay in completing clinical trials for our drug products, or in receiving regulatory approval for the sale of any drugs resulting from our drug products, may severely harm our business and reputation.reputation and may cause our stock price to decline. Even if we receive FDA and other regulatory approvals, our drug products may later exhibit adverse effects that may limit or prevent their widespread use, may cause the FDA to revoke, suspend or limit their approval, or may force us to withdraw products derived from those drug products from the market. Furthermore, there is the risk that additional post-marketing requirements may be imposed by the FDA in the future on our
products.
Moreover, the commencement and completion of clinical trials may be delayed by many factors that are beyond our control, including:
 
delays obtaining regulatory approval to commence a trial;
delays in reaching agreement on acceptable terms with contract research organizations or CROs,(“CROs”), and clinical trial sites;
delays in obtaining institutional review board, or IRB, approval at each site;

Table of Contents

our inability to retain patients who have initiated a clinical trial;
scheduling conflicts with participating clinicians and clinical institutions;
lack of funding to start or continue the clinical trial, including as a result of unforeseen costs due to enrollment delays, requirements to conduct additional trials and studies and increased expenses associated with our CROs and other third parties;
negative or inconclusive results;
deficiencies in the conduct of the clinical trial, including failure to conduct the clinical trial in accordance with regulatory requirements, GCPgood clinical practice, or clinical protocols;
deficiencies in the clinical trial operations or trial sites resulting in the imposition of a clinical hold;
patient noncompliance with the protocol;
adverse medical events or side effects experienced by patients during the clinical trials as a result of or resulting from the clinical trial treatments;
fatalities or other adverse events arising during a clinical trial due to medical problems that may not be related to clinical trial treatments;
our ability to sustain the quality or stability of the applicable product candidate in compliance with acceptable standards;
our inability to produce or obtain sufficient quantities of the applicable product candidate to complete the clinical trials;
changes in governmental regulations or administrative actions that adversely affect our ability to continue to conduct or complete clinical trials;
negative or problematic FDA inspections of our clinical operations or manufacturing operations; and
real or perceived lack of effectiveness or safety.
We could encounter delays if a clinical trial is suspended or terminated by us, the IRBs of the clinical trial sites in which such trials are being conducted, or by the FDA or other regulatory authorities. Such authorities may impose such a suspension or termination due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a drug, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. Any delays, interruptions or halts in our clinical trials involving any of our products or other adverse events negatively impacting our ability to obtain regulatory approvals for such products in a timely manner could adversely affect our overall profitability, results of operations and financial condition and prospects.

We will not generate any future revenue until our pipeline products, including the late-stage development products eflapegrastim and poziotinib, are currently conducting clinical trialsapproved for poziotinib. This product will require significant further development, including financial resources and personnel to possibly obtain regulatory approval. In December 2018, we submitted our NDA tocommercial sale by the FDA for ROLOTNIS. Due to the uncertain and time-consuming clinical development andand/or other regulatory approval process, we may not successfully develop these drugs or others, and thus it is possible that none of our pipeline compounds will ever become viable commercial products.

The announcement of any negative or unexpected data, any delay in our anticipated timelines for filing for regulatory approval, or a significant advancement of a competitor, may cause our stock price to decline significantly and may have an adverse impact on our business, financial condition and prospects.

PricingThe COVID-19 pandemic and mitigation measures also have had an adverse impact on global economic conditions which could have an adverse effect on our business and financial condition, including impairment of our ability to raise capital when needed. The trading prices for biopharmaceutical companies’ stock have been highly volatile as a result of the COVID-19 pandemic. In addition, the continued spread of COVID-19 could cause a recession, depression, or other sustained adverse market event which could materially and adversely affect our business and the value of our common shares.

We have maintained our operations during the COVID-19 pandemic by requiring most of our employees to work remotely. Only those employees performing essential activities that must be completed on-site are allowed in our facilities. These modifications to business activity may negatively impact productivity and cause disruptions and delays to our business. Longer term remote working environments could increase our cyber security risk, create data accessibility concerns, and make us more susceptible to communication disruptions. When we reopen our facilities, we could encounter delays in connection with implementing precautionary measures to mitigate the risk of exposing our employees to COVID-19.

Although the COVID-19 pandemic has not materially affected our clinical development programs to date, certain of our clinical programs have seen slower enrollment and there have also been delays in initiating new studies as a result of the COVID-19 pandemic. These delays are not seen across all our trials and are specific to certain trials enrolling at certain sites. In the future, the COVID-19 pandemic could further adversely affect our ability to enroll and recruit patients in current and future clinical trials, as well as delay data collection and analysis, any of which could cause a delay or denial of regulatory approval of our product candidates. Our success is dependent on our ability to advance our development programs into later stages of clinical development. Many pharmaceutical and biotechnology companies have indicated that their clinical trials will be delayed and enrollment of current and ongoing trials will suffer as a result of the COVID-19 pandemic. We anticipate the potential for delays in the initiation and enrollment of planned clinical trials until the pandemic resolves.
On October 26, 2020, we announced that the FDA had deferred action on the BLA for eflapegrastim due to its inability to conduct an inspection of the Hanmi manufacturing facility in South Korea as a result of travel restrictions associated with the COVID-19 pandemic. In early June 2021, the FDA conducted the pre-approval inspection of the Hanmi manufacturing facility. In August 2021, we received a Complete Response Letter from the FDA regarding our BLA, citing deficiencies related to manufacturing and indicating that a reinspection will be necessary. We believe we have completed the remediation of these deficiencies and resubmitted the BLA on March 11, 2022. However, we cannot guarantee that we, together with our contract manufacturers, will be able to remediate the cited deficiencies in a timely manner, or at all, and we cannot predict whether the COVID-19 pandemic will again delay or even prevent the FDA from completing any reinspections that may be required in connection with a resubmission of the BLA for efapegrastim.

The COVID-19 pandemic could also adversely affect our supply chain for other third party vendors for research supplies, development activities including manufacturing of drug product for our clinical studies and testing of drug material. If any of the vendors in our supply chain of products has come under increasing scrutinyor services are severely affected from the COVID-19 pandemic, it will adversely affect our ability to continue our research and development activities and also continue our clinical trial activities. Disruptions to our business operations or operations of our third-party manufacturers and CROs on which we rely to conduct our clinical trials could be significant and of undetermined length. Significant restrictions or bans on travel could impede, delay, limit or prevent our employees and CROs from continuing research and development activities.

The pharmaceutical and biotechnology industries are intensely competitive. We are aware of several competitors attempting to develop and market products competitive to our in-development products, which may reduce or eliminate our commercial opportunities in the future.
The pharmaceutical and biotechnology industries are intensely competitive and subject to rapid and significant technological changes. A number of companies are pursuing the development of pharmaceuticals and products that target the same diseases and conditions that our pipeline products target. We cannot predict with accuracy the timing or impact of the introduction of potentially competitive products or their possible effect on our future sales. Certain potentially competitive products to our in-development products are in various stages of development, some of which have pending applications for approval with the FDA or have been approved by governments, legislative bodiesregulatory authorities in other countries. Also, there are many ongoing studies with currently marketed products and enforcement agencies. Changesother developmental products, which may yield new data that could adversely impact the use of our products upon potential FDA approval. Some of our in-development products may become obsolete before we recover the expenses incurred in laws and regulationstheir development. The introduction of competitive products or the development of technological advances that control drug pricing for government programs, allow for negotiated pricing, or limit product coverage and reimbursements maycompete with our products could significantly reduce anticipated future sales, which, in turn would adversely impact our financial and operating results and our business.
Many companies in our industry have received a governmental request for documents and information relating to drug pricing and patient assistance programs. We may become subject to similar requests, which would require us to incur significant expense and result in distraction for our management team. Additionally, to the extent there are findings, or even allegations, of improper conduct on the part of the company or its employees, such findings or allegations could result in negative publicity or other negative actions that could harm our reputation; cause changes in our product pricing and distribution strategies; reduce demand for our approved products and/or reduce reimbursement of approved products, including by federal health care programs such as Medicare and Medicaid and state health care programs.
In addition, President Trump’s administration has indicated an interest in taking measures pertaining to drug pricing, including potential proposals relating to Medicare price negotiations, and importation of drugs from other countries. There have been several recent U.S. Congressional inquiries and proposed bills designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs under Medicare, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs. At this time, it is unclear whether any of these proposals will be pursued; however, if pursued they could adversely affect our products or our future product candidates.

results.
Our supply of APIs and drug products is and will beremain dependent upon the production capabilities of contract manufacturing organizations, or CMOs component and packaging supply sources, other third-party suppliers, and other providers ofthird-parties for related supplies and logistical services. Some of these partiesvendors are based overseasoverseas. If our CMOs and if theyother suppliers are not able to meet our demands andrequirements or FDA scrutiny, we may be unable to obtain approval for our products. Even if we do obtain approval for our products, we may be limited in our ability to meet demand for our products, ensure regulatory compliance, or maximize profit on the future sale of our products. Any manufacturing-related disruptions could create significant demand on our limited capital resources, and there can be no assurance that we would be able to continue as a going concern. In addition, our dependence on these ex-U.S. vendors also subjects us to business interruption risks related to COVID-19, and/or similar outbreaks, which could have a material adverse impact on us.

We have no internal manufacturing capacity for APIs or our drug products, and,products. We therefore we have entered into agreements with CMOs and other suppliers to supply us with APIs and our finished drug product.products. Success in the development and marketing of our drug products depends, in part, upon our ability to maintain, expand and enhance ourthese existing relationships and establish new sources of supply. Some of the third-party manufacturing facilities used in the production of APIs and our drug products are located outside the U.S. The manufacture of APIs and finished drug products, including the acquisition of compounds used in the manufacture of the finished drug product,products, may require considerable lead times. We have little or no control over the production processes of third-party manufacturers, CMOs or other suppliers. Some of the third-party manufacturing facilities used in the production of APIs and our drug products are located outside of the U.S. and require FDA approval, which our third-party manufacturers may have limited experience with obtaining. Our CMOs and other suppliers are subject to inspection by the FDA and may receive observations that they may not be able to resolve in a timely or effective manner, which could impact whether our products can be approved on a timely basis, if at all. We recently received a Complete Response Letter from the FDA on August 6, 2021 for our eflapegrastim BLA that cited various manufacturing deficiencies at our API and our fill-and-finish suppliers. There is no guarantee that the remediation efforts will be found to be acceptable by the FDA.

The manufacture of pharmaceutical products requires significant expertise and capital investment, including the development of manufacturing and testing techniques, process controls, and scaling of production to meet commercial requirements. Manufacturers of pharmaceutical products often encounter difficulties during preparation for production, including technical challenges production costs, yields, quality control and assurance. If manufacturing deficiencies are noted by the FDA at any of the manufacturing facilities utilized in our products, there can be no assurance that we, or our CMOs, can resolve these manufacturing deficiencies on a timely basis, if at all. Any manufacturing-related disruptions could create significant demand on our limited capital resources, and there can be no assurance that we would be able to continue as a going concern.

Our ability to source APIs and drug products is also dependent on providers of logistical services who may be subject to disruptions that we cannot predict or sufficiently plan around. Accordingly, while we do not currently anticipate shortages of supply, circumstances could arise in which we will not have adequate supplies to timely meet our requirements or market demand for a particular drug product could outstrip the ability of our supply source to timely manufacture and deliver the product, thereby causing us to lose sales. In addition, our ability to make a profit on the sale of our drug products depends on our ability to obtain price arrangements that ensure a supply of product at favorable prices.pricing for these arrangements.

If problems arise during the productionmanufacture of a batch of our drug products, that batch of product may have to be discarded. This could, among other things, lead to increased costs, lost revenue, damage to customer relations, time and expense spent investigating the cause of the problem and, depending on the cause, similar losses with respect to other batches or products. If problems are not discovered before the product is released to the market, recall and product liability costs may also be incurred. To the extent that one of our suppliers experiences significant manufacturing problems, this could have a material adverse effect on our revenues and profitability.
Finally, reliance
Reliance on CMOs entails risks to which we would not be subject if we manufactured products ourselves, including reliance on the third party for regulatory compliance and adherence to the cGMP,FDA’s current Good Manufacturing Practice (“cGMP”) requirements, the possible breach

Table of Contents


of the manufacturing agreement by the CMO and the possibility of termination or non-renewal of the agreement by the CMO, based on its own business priorities, at a time that is costly or inconvenient for us. Before we can obtain marketing approval for our drug products, our CMO facilities must be approved by the FDA and typically pass an FDAa pre-approval inspection. In order to obtain FDA approval, the FDA must conclude that all of the facility’ssuppliers’ manufacturing methods, equipment and processes must comply with cGMP requirements.

The cGMP requirements govern all areasorganization and personnel, buildings and facilities, equipment, control of record keeping,components and drug product containers and closures, production processes and process controls, personnelpackaging and quality control.labeling control, holding and distribution, laboratory controls, records and reports, and returned and salvaged drug products. In addition, our CMOs will be subject to on-going periodic inspection by the FDA and corresponding state and foreign agencies for compliance with their cGMP regulations, similar foreignrequirements, regulations and other regulatory standards. We do not have control over our CMOs’ compliance with these regulations and standards. Any failure of our third party manufacturers or us to comply with applicable regulations, including an FDA pre-approval inspection, periodic on-going inspection by the FDA and cGMP requirements, could result in sanctions being imposed on them or us, including warning letters, fines, injunctions, civil penalties, failure of regulatory authorities to grant marketing approval of our products, delay, suspension or withdrawal of approvals, license revocation, seizures or recalls of product, operation restrictions and criminal prosecutions, any of which could significantly and adversely affect our business.


Finally, our business could be adversely impacted by the effects of the COVID-19 pandemic, or by other public health emergencies. We source some of our APIs and other materials from Asia, including China and South Korea. Due to our current
19

Table of Contents

reliance on these vendors for eflapegrastim and poziotinib supply, we risk disruption in our supply chain (including restrictions on export or shipment), depending on the severity of the coronavirus outbreak and the potential government restrictions placed on our vendors or their transports.

If our suppliers fail to deliver materials and services needed for commercial manufacturing in a timely and sufficient manner or fail to comply with applicable regulations, and if we fail to timely identify and qualify alternative suppliers, our business, financial condition and results of operations would be harmed and the market price of our common stock and other securities could decline.

We must rely on all of our suppliers to comply with relevant regulatory and other legal requirements, including the production of API in accordance with the FDA’s cGMP for drug products. Although we conduct our own inspections and review and/or approve investigations of each supplier, there can be no assurance that the FDA, upon inspection, would find that the supplier is complying with the cGMP requirements, where applicable. If a supplier fails to comply with these requirements or the comparable requirements in foreign countries, regulatory authorities may subject them or us to regulatory action, including criminal prosecutions, fines and suspension of the manufacture of our products. If we are required to find a new or additional supplier, we will need to evaluate that supplier’s ability to provide material that meets regulatory requirements, including cGMP requirements, as well as our specifications and quality requirements, which would require significant time and expense and could delay the production of our drug products. In general, if any of our suppliers is unwilling or unable to meet its supply obligations or if we encounter delays or difficulties in our relationships with manufacturers or suppliers, and we are unable to secure an alternative supply source in a timely manner and on favorable terms, our business, financial condition, and results of operations may be harmed and the market price of our common stock may decline.
Our future sales will depend on coverage and reimbursement from third-party payers and a reduction in the coverage and/or reimbursement for our products could have a material adverse effect on our product sales, business and results of operations.
Upon FDA approval, sales of our products are dependent on the availability and extent of coverage and reimbursement, or level of reimbursement, from third-party payers, including government programs and private insurance plans. Governments and private payers may regulate prices, reimbursement levels and/or access to our products to contain costs or to affect levels of use. We rely in large part on the reimbursement of our products through government programs such as Medicare and Medicaid in the U.S., and a reduction in the coverage and/or reimbursement for our products could have a material adverse effect on our product sales, business and results of operations.
A substantial portion of our U.S. business is expected to rely on reimbursement from the U.S. federal government under Medicare Part B coverage. Most of our products furnished to Medicare beneficiaries in both a physician office setting and hospital outpatient setting will be reimbursed under the Medicare Part B Average Sales Price (“ASP”) payment methodology. ASP-based reimbursement of our products under Medicare may be below or could fall below the cost that some medical providers pay for such products, which could materially and adversely affect sales of our products. We also face risks relating to the reporting of pricing data that affect the U.S. reimbursement of and discounts for our products. ASP data are calculated by the manufacturer based on a formula defined by statute and regulation and are then submitted to the Centers for Medicare & Medicaid Services (“CMS”), the agency responsible for administering the Medicare program, on a quarterly basis.
CMS uses those ASP data to determine the applicable reimbursement rates for our products under Medicare Part B. However, the statute, regulations and CMS guidance do not define specific methodologies for all aspects of the reporting of ASP data. For example, CMS has not provided specific guidance regarding administrative fees paid to group purchasing organizations (each a “GPO” and, collectively “GPOs”) in the ASP calculation. CMS directs that manufacturers make “reasonable assumptions” in their calculation of ASP data in the absence of specific CMS guidance on a topic. As a result, we are required to apply our reasonable judgment to certain aspects of calculating ASP data. If our submitted ASP data are incorrect, we may become subject to substantial fines and penalties or other government enforcement actions, which could have a material adverse impact on our business and results of operations.
A breakdown or breach of our information technology systems and cybersecurity efforts could subject us to liability, reputational damage or interrupt the operation of our business.
We rely upon our sophisticated information technology systems and infrastructure to operate our business.  In the ordinary course of business, we collect, store and transmit large amounts of confidential information (including, but not limited to, personal information and intellectual property), and we deploy and operate an array of technical and procedural controls to maintain the confidentiality and integrity of such confidential information.  Data privacy breaches by those who access our systems, whether by employees or others, may pose a risk that sensitive data, including intellectual property, trade secrets or
20

Table of Contents

personal information belonging to us, our patients, employees, customers or other business partners, may be exposed to unauthorized persons or to the public or otherwise used for unauthorized purposes. We could also experience a business interruption, noncompliance with data privacy laws, theft of confidential information, or reputational damage from industrial espionage attacks, malware or other cyber-attacks, which may compromise our system infrastructure or lead to data leakage, either internally or at our third-party providers.  Such attacks are of ever-increasing levels of sophistication, frequency and intensity, and have become increasingly difficult to detect. There can be no assurance that our efforts to protect our data and information technology systems will prevent breakdowns or breaches in our systems (or that of our third-party providers). Any such interruption or breach of our systems or improper use of confidential data could adversely affect our business operations, financial condition, and/or result in the loss of critical or sensitive confidential information or intellectual property, and could result in financial, legal, business and reputational harm to us.
We are also subject to various laws and regulations globally regarding privacy and data protection, including laws and regulations relating to the collection, storage, handling, use, disclosure, transfer and security of personal data. The legislative and regulatory environment regarding privacy and data protection is continuously evolving and developing and the subject of significant attention globally. We are subject to the EU’s General Data Protection Regulation, which became effective in May 2018, and the California Consumer Privacy Act of 2018, which became effective in January 2020, each of which contemplate substantial penalties. Failure to comply with these laws could result in significant penalties and could have a material adverse effect on our business and results of operations.
Reports of adverse events or safety concerns involving our in-development products or similar agents, could delay or prevent us from obtaining or maintaining regulatory approval or negatively impact sales.
Our in-development products may cause SAEs. In addition to the risk associated with known SAEs, discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, could interrupt, delay or halt clinical trials of such products, including the FDA-required post-approval studies, and could result in the FDA or other regulatory authorities denying or withdrawing approval of our products for any or all indications. The FDA, other regulatory authorities or we may suspend or terminate clinical trials at any time. We may also be required to update the package inserts based on reports of adverse events or safety concerns or implement a REMS, which could adversely affect such product’s acceptance in the market. In addition, the public perception of our products might be adversely affected, which could harm our business and results of operations and cause the market price of our common stock to decline, even if the concern relates to another company’s product or product candidate. Our planned trials to demonstrate efficacy in a variety of indications and to better manage side effect profiles of certain of our products may not be successful and there are no assurances that patients receiving our products will not experience SAEs in the future.
Future reports of SAEs or safety concerns involving any of our products could adversely affect our business, results of operations and prospects.
Our dependence on key executives, scientists and sales and marketing personnel could impact the development and management of our business.
We are highly dependent upon our ability to attract and retain qualified scientific, technical sales and marketing and managerial personnel. There is intense competition for qualified personnel in the pharmaceutical and biotechnology industries, and we cannot be sure that we will be able to continue to attract and retain the qualified personnel necessary, particularly as business prospects change, for the development and management of our business. Although we do not believe the loss of one individual would materially harm our business, our business might be harmed by the loss of the services of multiple existing personnel, as well as the failure to recruit additional key scientific, technical and managerial personnel in a timely manner. Much of the know-how we have developed resides in our scientific and technical personnel and is not readily transferable to other personnel. We do not have employment agreements with most of our key scientific, technical, or managerial employees, though we have employment agreements with each of our named executive officers. Furthermore, our common stock is currently trading at a price below the exercise price of most of our outstanding stock options. As a result, these “underwater” options are less useful as a motivation and retention tool for our existing employees.
A significant portion of our revenue has historically been derived from a limited number of distributors - and is expected to persist for our in-development drugs upon potential FDA approval.
    We expect that a significant portion of our future revenue will depend on sales to a limited number of distributors. Any distributors we may use comprise a significant part of the distribution network for pharmaceutical products in the U.S. and a small number of large distributors and wholesalers control a significant share of the market, which can increase competitive and pricing pressures on pharmaceutical manufacturers, including us. In addition, wholesalers may apply pricing pressure through
21

Table of Contents

their fee-for-service arrangements. Any reduction in the prices we receive for our products could adversely impact our revenues and financial condition. In addition, any individual distributor could choose to stop selling some or all of our products at any time, and without notice. If we lose our relationship with any of our future significant distributors, we would experience disruption and delays in marketing our products and could also experience declines in our revenues, which in turn could materially adversely impact our financial condition.
Our efforts to acquire or in-license and develop additional drug products may fail and/or acquired orour in-licensed products may fail to perform as we anticipate, which might limit our ability to grow our business.
To remain competitive and grow our business, our long-term strategy includes the acquisition or in-license of additional drug products. We are actively seeking to acquire, or in-license, additional commercial drug products as well as drug products that have demonstrated positive pre-clinical and/or clinical data. We have certain criteria that we are looking for in any drug product acquisition and in-license and we may not be successful in locating and acquiring, or in-licensing, additional desirable drug products on acceptable terms.
To accomplish our acquisition and in-license strategy, we intend to commit efforts, funds and other resources to research and development and business development. Even with acquired and in-licensed drug products, a high rate of failure is inherent in the development of such products. We must make ongoing substantial expenditures without any assurance that our efforts will be commercially successful. Failure can occur at any point in the process, including after significant funds have been invested. For example, promising new drug product candidates may fail to reach the market or may only have limited commercial success because of efficacy or safety concerns, failure to achieve positive clinical outcomes, inability to obtain necessary regulatory approvals, limited scope of approved uses, excessive costs to manufacture, the failure to establish or maintain intellectual property rights, limited payer coverage or infringement of the intellectual property rights of others.
In addition, many other large and small companies within the pharmaceutical and biotechnology industry seek to establish collaborative arrangements for product research and development, or otherwise acquire products in late-stage clinical development, in competition with us. We face additional competition from public and private research organizations, academic institutions and governmental agencies in establishing collaborative arrangements for drug products in late-stage clinical development. Many of the companies and institutions that compete against us have substantially greater capital resources, research and development staffs and facilities than we have, and greater experience in conducting business development activities. These entities represent significant competition to us as we seek to expand our portfolio through the in-license or acquisition of compounds. Finally, while it is not feasible to predict the actual cost of acquiring and developing additional drug products, that cost could be substantial and we may need to obtain additional financing for such purpose, which may further dilute existing stockholders.
We are aware of several competitors attempting to develop and market products competitive to our products, which may reduce or eliminate our commercial opportunities.
The pharmaceutical and biotechnology industries are intensely competitive and subject to rapid and significant technological changes, and a number of companies are pursuing the development of pharmaceuticals and products that target the same diseases and conditions that our products target, including products currently commercialized. We cannot predict with accuracy the timing or impact of the introduction of potentially competitive products or their possible effect on our sales. Certain potentially competitive products to our products are in various stages of development, some of which have pending applications for approval with the FDA or have been approved by regulatory authorities in other countries. Also, there are many ongoing studies with currently marketed products and other developmental products, which may yield new data that could adversely impact the use of our products in their current and potential future indications. The introduction of competitive products or the development of technological advances that compete with our products could significantly reduce our sales, which, in turn would adversely impact our financial and operating results.

Reports of adverse events or safety concerns involving each of our products or similar agents, sold by us or our development partners and/or licensees, could delay or prevent us from obtaining or maintaining regulatory approval or negatively impact sales.
Certain of our products may cause SAEs. In addition to the risk associated with known SAEs, discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, could interrupt, delay or halt clinical trials of such products, including the FDA-required post-approval studies, and could result in the FDA or other regulatory authorities denying or withdrawing approval of our products for any or all indications. The FDA, other regulatory authorities or we may suspend or terminate clinical trials at any time. We may also be required to update the package inserts based on reports of adverse events or safety concerns or implement a risk evaluation and mitigation strategy, or REMS, which could adversely affect such product’s acceptance in the market. In addition, the public perception of our products might be adversely affected, which could harm ourOur business and results of operations and cause the market price of our common stock to decline, even if the concern relates to another company’s product or product candidate. Our planned trials to demonstrate efficacy in a variety of indications and to better manage side effect profiles of certain of our products may not be successful and there are no assurances that patients receiving our products will not experience SAEs in the future.
Future reports of SAEs or safety concerns involving any of our products could adversely affect our business, results of operations and prospects.
The known SAEs related to our commercialized products are as follows:

FOLOTYN:

Forty-four percent of patients experienced a serious adverse event while on the study or within 30 days after their last dose. The most common serious adverse events (> 3%), regardless of causality, were fever, mucositis (redness and sores of the mucous membrane lining of the mouth, lips, throat, stomach, and genitals), sepsis (complication of infection), febrile neutropenia (fever associated with low white blood cell count), dehydration, dyspnea (shortness of breath), and thrombocytopenia (low platelet count). One death from cardiopulmonary arrest in a patient with mucositis and febrile neutropenia was reported in this trial. Deaths from mucositis, febrile neutropenia, sepsis, and pancytopenia (deficiency of all three cellular components of the blood) occurred in 1.2% of patients treated on all FOLOTYN trials at doses ranging from 30 to 325 mg/m2.

FOLOTYN may cause serious side effects, including bone marrow suppression, manifested by thrombocytopenia (low platelet counts), neutropenia (low white blood cell counts), and/or anemia (low red blood cell count); mucositis (redness and sores of the mucous membrane lining of the mouth, lips, throat, stomach, and genitals); dermatologic reactions (severe skin reactions); tumor lysis syndrome (tumor cells releasing contents into blood stream); hepatic toxicity (harm to liver); risk of increased toxicity in the presence of impaired renal function (increased harm to the patients with abnormal kidney function); and embryo-fetal toxicity (harm to an unborn baby).

ZEVALIN:

ZEVALIN is associated with the following serious adverse reactions: serious infusion reactions, prolonged and severe cytopenias (low blood cell count), cutaneous and mucocutaneous (skin and mucus membrane) reactions, and leukemia and myelodysplastic syndrome. The most serious adverse reactions of ZEVALIN are prolonged and severe cytopenias (low platelets, red blood cells, lymphocytes, white blood cells) and secondary malignancies.

MARQIBO:

Seventy-six percent of patients experienced serious adverse events during the studies. The most commonly reported serious adverse events (> 6%) included, febrile neutropenia (fever associated with low white blood cell count), fever, low-blood pressure, respiratory distress, and cardiac arrest.

MARQIBO may cause serious side effects, including extravasation tissue injury (leakage-induced tissue injury); neurologic toxicity (nerve problems, e.g., neuropathy); myelosuppression (low blood cell counts); tumor lysis syndrome (tumor cells releasing contents into blood stream); constipation and bowel obstruction (constipation and bowel blockage); fatigue (tiredness); hepatic toxicity (harm to liver); and embryo-fetal toxicity (harm to an unborn baby).

BELEODAQ:


26

Table of Contents


Forty-seven percent of patients experienced serious adverse reactions while taking BELEODAQ or within 30 days after their last dose of BELEODAQ. The most common serious adverse reactions (> 2%) were pneumonia, fever, infection, anemia (low red blood cell count), increased creatinine, thrombocytopenia (low platelet count), and multi-organ failure. One treatment-related death associated with hepatic failure was reported in the trial.

BELEODAQ may cause serious side effects, including hematologic toxicity (low blood cell counts); serious infections; hepatotoxicity (liver problems); tumor lysis syndrome (tumor cell releasing contents into blood stream); gastrointestinal toxicity, including nausea, vomiting, and diarrhea; and embryo-fetal toxicity (harm to an unborn baby).

EVOMELA:

Twenty percent of patients experienced a treatment emergent serious adverse reaction while on study. The most common serious adverse reactions (>1 patient, 1.6%) were fever, hematochezia (blood in stools), febrile neutropenia (fever associated with low white blood cell count), and kidney failure. Treatment-related serious adverse reactions reported in >1 patient were pyrexia, febrile neutropenia, and hematochezia.

EVOMELA may cause serious side effects, including bone marrow suppression (low blood cell counts); gastrointestinal toxicity, including nausea, vomiting, diarrhea and mucositis (redness and sores of the lining of the mouth, lips, throat, stomach, and genitals); hepatotoxicity (liver problems); hypersensitivity (allergic reactions); secondary malignancies (secondary cancers); embryo-fetal toxicity (harm to an unborn baby); and infertility (harm to reproductive system).

KHAPZORY:

The most common adverse reactions (>20%) in patients receiving high-dose methotrexate therapy with levoleucovorin rescue were stomatitis (38%) and vomiting (38%). The most common adverse reactions (>50%) in patients receiving levoleucovorin in combination with fluorouracil for metastic colorectal cancer were stomatitis (72%), diarrhea (70%), and nausea (62%).
Our dependence on key executives, scientists and sales and marketing personnel could impact the development and management of our business.
We are highly dependentdepends upon our ability to attract and retain qualified scientific, technical sales and marketing and managerial personnel. There is intense competition for qualified personnel in the pharmaceutical and biotechnology industries, and we cannot be sure that we will be able to continue to attract and retain the qualified personnel necessary, particularly as business prospects change, for the development and management of our business. Although we do not believe the loss of one individual would materially harm our business, our business might be harmed by the loss of the services of multiple existing personnel, as well as the failure to recruit additional key scientific, technical and managerial personnel in a timely manner. Much of the know-how we have developed resides in our scientific and technical personnel and is not readily transferable to other personnel. We do not have employment agreements with most of our key scientific, technical, or managerial employees. However, we entered into new employment agreements with each of our named executive officers (chief executive officer, chief operating officer, chief financial officer, and chief legal officer) in April and June 2018, which supersede any prior Change in Control Severance Agreements with such individuals.
A significant portion of our revenue currently comes from a limited number of distributors, and any decrease in revenue from these distributors could harm our business
A significant portion of our revenue comes from a limited number of distributors. In the years ended December 31, 2018 and December 31, 2017, three distributors (and their affiliates) together represented approximately 88% and 90%, respectively, of our worldwide revenues. We expect that a significant portion of our future revenue will continue to depend on sales to a limited number of distributors in the foreseeable future. We do not have long-term commitments from our distributors to carry our products, and any of our distributors may from quarter to quarter comprise a significant concentration of our revenues. These distributors comprise a significant part of the distribution network for pharmaceutical products in the U.S. and a small number of large distributors and wholesalers control a significant share of the market, which can increase competitive and pricing pressures on pharmaceutical manufacturers, including us. In addition, wholesalers may apply pricing pressure through their fee-for-service arrangements. Any reduction in the prices we receive for our products could adversely impact our revenues and financial condition. In addition, any individual distributor could choose to stop selling some or all of our products at any time, and without notice. If we lose our relationship with any of our significant distributors, we would experience

disruption and delays in marketing our products and could also experience declines in our revenues which in turn could materially adversely impact our financial condition.
If the distributors that we rely upon to sell our products fail to perform, our business may be adversely affected.
Our success depends on the continued customer support efforts of our network of distributors.
In the U.S., we plan to sell our products to a small number of distributors who in turn will sell-through to patient health care providers. These distributors will also provide multiple logistics services relating to the distribution of ourdrug products, including transportation, warehousing, cross-docking, inventory management, packaging and freight-forwarding. We dowill not promote products to these distributors and they do not set or determine demand for products. The use of distributors involves certain risks, including, but not limited to, risks that these distributors will:
 
not provide us with accurate or timely information regarding their inventories, the number of patients who are using our products or complaints about our products;
not purchase sufficient inventory on hand to fulfill end user orders in a timely manner;
be unable to satisfy financial obligations to us or others; and
cease operations.
Any such actions may result in decreased sales of our products, upon potential FDA approval, which would harm our business.
Adverse economic conditions may have material adverse consequences on our business, results of operations and financial condition as well as our ability to raise additional capital.
Unpredictable and unstable changes in economic conditions, including recession, inflation, increased government intervention, or other changes, may adversely affect our general business strategy. In recent years, we have funded our
22

Table of Contents

operations through a combination of equity and debt offerings and sales of our pharmaceutical products. Based on our current plans and expectations, we believe that we will require additional funding to achieve our goals. We may need to raise these additional funds through public or private debt or equity financings, and any adverse economic conditions could adversely affect our ability to raise funds. If our business deteriorates, we may not be able to maintain compliance with any covenants or representations and warranties in any such financings, which could result in reduced availability of such financings, an event of default under such financings, or could make other sources of financing unavailable to us. Any such event would have a material adverse impact on our business, results of operations and financial condition.
While we believe we have adequate capital resources to meet our current working capital and capital expenditure requirements, an economic downturn or an increase in our expenses could require us to seek additional financing on less than attractive rates or on terms that are excessively dilutive to existing stockholders. Failure to secure any necessary financing in a timely manner and on favorable terms could have a material adverse effect on our growth strategy, financial performance and stock price and could require us to delay or abandon clinical development plans or plans to acquire additional technology.
Volatile economic conditions may not only limit our access to capital, but may also make it difficult for our customers and us to accurately forecast and plan future business activities, and they could cause businesses to slow spending on our products, which would delay and lengthen future sales cycles. Furthermore, during challenging economic times, our customers may face issues gaining timely access to sufficient credit, which could result in an impairment of their ability to make timely payments to us. In addition, adverse economic conditions could also adversely impact our suppliers’ ability to provide us with materials which would negatively impact on our business, financial condition, and results of operations.
We are a small company relative to our principal competitors, and our limited financial resources may limit our ability to develop and market our drug products.
Many companies, both public and private, including well-known pharmaceutical companies and smaller niche-focused companies, are developing products to treat many, if not all, of the diseases we are pursuing or are currently distributing drug products that directly compete with the drugs that we sell or that we intend to develop, market and distribute.
Competition for branded or proprietary drugs is less driven by price and is more focused on innovation in the treatment of disease, advanced drug delivery and specific clinical benefits over competitive drug therapies. We may not be successful in any or all of our current clinical studies; or if successful, and if one or more of our drug products is approved by the FDA, we may

encounter direct competition from other companies who may be developing products for similar or the same indications as our drug products.
Companies that have products on the market or in research and development that target the same indications as our in-development products or new compounds sought include, among others,others: Amgen, Inc., Coherus BioSciences, Mylan Pharmaceuticals, Inc., Sandoz, Pfizer, AstraZeneca plc, Bayer AG, Endo International plc, Eli LillyTakeda Pharmaceutical Company Ltd., Janssen Research & Development, Taiho Pharmaceutical Co., Ltd., Cullinan Oncology, LLC, Daiichi-Sankyo Co., Ltd., Genentech, Inc., Gilead Sciences, Inc., Jiangsu Hengrui Pharmaceuticals Co., Ltd., and Company, Novartis International AG Genentech, Inc. (Roche Holding AG), Bristol-Myers Squibb Company, Seattle Genetics, Inc., GlaxoSmithKline plc, Biogen Inc., OSI Pharmaceuticals, Inc. (Astellas Pharma Inc.), Cephalon, Inc. (Teva Pharmaceutical Industries Ltd.), Sanofi S.A., Pfizer, Inc., Merck & Co. Inc., Celgene Corporation, BiPar Sciences, Inc. (Sanofi S.A.), Sanofi Genzyme, Shire plc, AbbVie Inc., Poniard Pharmaceuticals, Inc., and Johnson & Johnson. These companies may be more advanced in the development of competing drug products or are more established in the market..
Many of our competitors are large and well-capitalized companies focusing on a wide range of diseases and drug indications, and have substantially greater financial, research and development, marketing, human and other resources than we do. Furthermore, large pharmaceutical companies have significantly more experience than we do in pre-clinical testing, human clinical trials and regulatory approval procedures, among other things. As a result, our competitors may be more successful than us in developing their products, obtaining regulatory approvals and marketing their products to consumers.

If actual future payments for allowances for discounts, returns, rebates and chargebacks exceed the estimates we made at the time of the sale of our products, including, without limitation, due to a change in the composition of our sales over time, our financial position, results of operations, and cash flows may be materially and negatively impacted.
On March 1, 2019, we completed the sale of the Commercial Product Portfolio to Acrotech. We recognize product revenue net ofcontractually retained all obligations related to our estimated allowances for discounts, returns, rebates and chargebacks. Such estimates require subjectivechargebacks for sales made on and complex judgment dueprior to the need to make estimates about matters that are inherently uncertain. Based on industry practice, pharmaceutical companies, including us, have liberal return policies.such date. Our former FUSILEV, MARQIBO, and BELEODAQ customers are permitted to return purchased products to us beginning at itstheir expiration date and within six months thereafter. Our former EVOMELA customers are permitted to return purchased product beginning at six months prior to its expiration date, and within 12 months following its expiration date (as well as for overstock inventory, as determined by end-users). We authorize returns for damaged products and exchanges for expired products in accordance with our returned goods policy and procedures. Also, like our competitors, we also give credits for chargebacks to wholesale customers that have contracts with us for their sales to hospitals, GPOs, pharmacies or other retail customers. The product revenue we recognized through March 1, 2019 was net of estimated allowances for discounts, returns,

rebates and chargebacks. Such estimates required subjective and complex judgment due to the need to make estimates about matters that are inherently uncertain. Based on industry practice, pharmaceutical companies, including us, have liberal return policies.
A chargeback is the difference between the price the wholesale customer (in our case, wholesalers/distributors)wholesaler pays us (wholesale acquisition cost)cost, or WAC) and the price that the wholesalers/distributor'swholesaler’s customer pays for aour product (contracted customer). Our products arewere subject to certain programs with federal government qualified entities whereby pricing on products is discounted to such entities and results in a chargeback claim to us.us, or for us to bill certain qualifying Public Health Service end-users at government-mandated pricing. To the extent that our sales to discount purchasers, such as federal government qualified entities, increases, our chargebackschargeback claims will also increase. There may be significant lag time between our original sale to the wholesaler and our receipt of the corresponding government chargeback claims from our wholesalers.
Our products are subject to state government-managed Medicaid programs, whereby rebates for purchases are issued to participating state governments. These rebates arise when the patient treated with our products is covered under Medicaid. Our calculations related to these Medicaid rebate accruals require us to estimate end-user and patient mix to determine which of our sales will likely be subject to these rebates. There is a significant time lag in us receiving these rebate notices (generally several months after our sale is made). Our estimates are based on our historical claims from participating state governments, as supplemented by management’s judgment.
Although we believe that we have sufficient allowances, actual results may differ significantly from our estimated allowances for discounts, returns, rebates and chargebacks. Changes in estimates and assumptions based upon actual results may have a material impact on our financial condition, results of operations and cash flows. Such changes to estimates will be made to the financial statements in the year in which the estimate is changed. In addition, our financial position, results of operations and cash flows may be materially and negatively impacted if actual future payments for allowances, discounts, returns, rebates and chargebacks exceed the estimates we made at the time of the sale of our products.
Our business and operations are subject to risks related to climate change.
The marketinglong-term effects of global climate change present risks to our business. Extreme weather or other conditions caused by climate change could adversely impact our supply chain and salethe availability and cost of raw materials and components required for the operation of our business. Such conditions could also result in physical damage to products, plants and distribution centers, as well as the infrastructure and facilities and other customers. In addition, regulations intended to limit greenhouse gas emissions, such as taxes on fuel and energy, to mitigate the impacts of climate change may beincrease, which could increase our operating costs and the costs charged by suppliers. These events could adversely affected by the marketingaffect our operations and sales efforts of third parties who sell our products or similar products outside of our territories.financial performance.
We have only licensed the rights to develop and market our products in limited territories. Other companies market and sell the same products in other parts of the world. If, as a result of other companies’ actions, negative publicity is associated with our products or similar products, our own efforts to successfully market and sell our products in our markets may be adversely impacted.

We have engaged in, and may in the futureOur business strategy requires that we engage in strategic transactions that increase our capital requirements, dilute our stockholders, cause us to incur debt or assume contingent liabilities, and subject us to other risks.possibly dilute our stockholders.
We actively evaluate various strategic transactions on an ongoing basis, including licensing or otherwise acquiring complementary products, technologies or businesses. Any potential acquisitions or in-licensing transactions may entail numerous risks, including but not limited to:
 
risks associated with satisfying the closing conditions relating to such transactions and realizing their anticipated benefits;
increased operating expenses and cash requirements;
difficulty in conforming standards, procedures and policies, business cultures and compensation structures;
difficulty integrating acquired technologies, products and personnel with our existing business;
difficulty conforming acquired operations, such as corporate and administrative functions, sales and marketing, or information technology and accounting systems with our existing business;
diversion of management’s attention in connection with both negotiating the acquisition or license and integrating the business, technology or product;
retention of key employeesemployees;
uncertainties in our ability to maintain key business relationships of any acquired entities;
strain on managerial and operational resources;

Table of Contents

exposure to regulatory, compliance and legal risks of the acquired entities;
tax costs or inefficiencies associated with integrating operations; 
modifications to operating control standards to comply with the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated thereunder;
difficulty coordinating geographically dispersed organizations;
exposure to unforeseen liabilities of acquired companies or products or companies or products in which we invest; and
potential costly and time-consuming litigation, including stockholder lawsuits.

As a result of these or other problems and risks, businesses, technologies or products we acquire or invest in or obtain licenses to may not produce the revenues, earnings or business synergies that we anticipated. In addition, acquired or licensed products may not perform as expected or we may not obtain necessary regulatory approvals on our anticipated timeline or at all.
As a result,Accordingly, we may incur higher costs and realize lower revenues than we had anticipated. We cannot assure you that any acquisitions or investments we have made or may make in the future will be completed or that, if completed, the acquired business, licenses, investments, products, or technologies will generate sufficient revenue to offset the negative costs or other negative effects on our business. Failure to effectively manage our growth through acquisition or in-licensing transactions could adversely affect our growth prospects, business, results of operations, financial condition, and cash flow.

In addition, in connection with acquisitions and in-licensing transactions, we may spend significant amounts of capital, issue dilutive securities, assume or incur significant debt obligations or contingent liabilities, and acquire intangible assets that could result in significant future amortization expense and write-offs. Moreover, we may not be able to locate suitable acquisition opportunities and this inability could impair our ability to grow or obtain access to technology or products that may be important to the development of our business. Even if appropriate opportunities are available, we may not be able to successfully identify them or we may not have the financial resources necessary to pursue them, and if pursued, we may be unable to structure and execute transactions in on our anticipated timeframe, or at all. Other pharmaceutical companies, many of which may have substantially greater financial, marketing and sales resources than we do, compete with us for these opportunities.

Even if we are able to successfully identify and acquire complementary products, technologies or businesses, we cannot assure you that we will be able to successfully manage the risks associated with integrating acquired products, technologies or businesses or the risks arising from anticipated and unanticipated problems in connection with an acquisition or in-licensing transaction. Further, while we seek to mitigate risks and liabilities of potential acquisitions and in-licensing transactions

through, among other things, due diligence, there may be risks and liabilities that such due diligence efforts fail to discover, that are not disclosed to us, or that we inadequately assess. Any failure in identifying and managing these risks and uncertainties effectively would have a material adverse effect on our business. Additionally, actual costs and sales synergies, if achieved at all, may be lower than we expect and may take longer to achieve than we anticipate. Furthermore, the products of companies we acquire may overlap with our products or those of our customers, creating conflicts with existing relationships or with other commitments that are detrimental to the integrated businesses.

If we are unable to successfully integrate our acquisitions with our existing business, we may not obtain the advantages that the acquisitions were intended to create, which may materially adversely affect our business, results of operations, financial condition and cash flows, our ability to develop and introduce new products and the market price of our stock.
Our divestiture activities, including the Acrotech Transaction, may disrupt our ongoing business, may involve increased expenses and may present risks not contemplated at the time of the transactions.
As previously discussed, we have entered into an agreement with Acrotech to divest certain assets that no longer fit with our strategic direction. We may in the future engage in additional divestiture transactions. Divestitures generally involve significant risks and uncertainties, including, without limitation:
our failure to effectively transfer contracts, facilities and employees to buyers;
requirements that we indemnify buyers against certain liabilities and obligations;
the possibility that we will become subject to third-party claims arising out of such divestitures;
challenges in identifying and separating the intellectual property and data to be divested from the intellectual property and data that we wish to retain;
our inability to reduce fixed costs previously associated with the divested assets;
challenges in collecting the proceeds from any divestiture;
disruption of our ongoing business and distraction of management; and
loss of key employees who leave our Company as a result of a divestiture.
Because divestitures are inherently risky, our transactions, including the Acrotech Transaction, may not be successful and may, in some cases, harm our operating results or financial condition.
We may not be able to successfully or timely complete the Acrotech Transaction, which could materially impact the market price of our Company’s common stock, as well as our future business prospects and our financial condition, results of operations and cash flows.
On January 17, 2019, we entered into a definitive asset purchase agreement with Acrotech for the sale of our FDA-approved product portfolio. The Acrotech Transaction may not be completed, or may not be completed in the timeframe, on the terms or in the manner currently anticipated. The completion of the Acrotech Transaction is subject to the satisfaction or waiver of customary closing conditions, such as receipt of certain regulatory approvals. There can be no assurance that these conditions will be satisfied or waived, or that other events will not intervene to delay or result in the failure to close the Acrotech Transaction.
In addition, while we believe that we will receive all required approvals for the Acrotech Transaction and Acrotech and we have agreed to use reasonable best efforts, subject to certain limitations, to obtain such approvals, there can be no assurance as to the receipt or timing of receipt of these approvals. As a condition to approving the Acrotech Transaction, governmental authorities may impose conditions, terms, obligations or restrictions or require divestitures or place restrictions on the conduct of the business after consummation of the Acrotech Transaction, including those which Acrotech may not be required to accept pursuant to the terms of the executed asset purchase agreement. A substantial delay in obtaining any required authorizations or approvals or the imposition of unfavorable terms, conditions or restrictions contained in such authorizations or approvals, could prevent the completion of the Acrotech Transaction or have an adverse effect on the anticipated benefits of the Acrotech Transaction. If the Acrotech Transaction is not consummated in a timely manner or at all, our ongoing business may be materially adversely affected, including without limitation, as follows:
we may experience negative reactions from financial markets and our stock price could decline;
we may experience negative reactions from employees, customers, suppliers or other third parties;

31

Table of Contents


our management’s focus would have been diverted from pursuing other valuable opportunities; and
the costs of completing the Acrotech Transaction may be higher than anticipated and, in any event, would be borne entirely by us.
Our collaborations with outside scientists may be subject to change, which could limit our access to their expertise.
We work with scientific advisors and collaborators at research institutions. These scientists are not our employees and may have other commitments that would limit their availability to us. If a conflict of interest between their work for us and their work for another entity arises, we may lose their services, which could negatively impact our research and development activities.

We may rely on CROs and other third parties to conduct clinical trials and, in such cases, we are unable to directly control the timing, conduct and expense of our clinical trials.
We may rely, in full or in part, on third parties to conduct our clinical trials. In such situations, we have less control over the conduct of our clinical trials, the timing and completion of the trials, the required reporting of adverse events and the management of data developed through the trial than would be the case if we were relying entirely upon our own staff.

Table of Contents

Communicating with outside parties can also be challenging, potentially leading to mistakes as well as difficulties in coordinating activities. Outside parties may have staffing difficulties, may undergo changes in priorities or may become financially distressed, adversely affecting their willingness or ability to conduct our trials. We may experience unexpected cost increases that are beyond our control. Problems with the timeliness or quality of the work of a CRO may lead us to seek to terminate the relationship and use an alternative service provider. However, making this change may be costly and may delay our trials, and contractual restrictions may make such a change difficult or impossible. Additionally, it may be challenging or impossible to find a replacement organization that can conduct our trials in an acceptable manner and at an acceptable cost.

Competition for patients in conducting clinical trials may prevent or delay product development and strain our limited financial resources.
BecauseMany pharmaceutical companies are conducting clinical trials involving patients with the disease indications that our drug products target. As a result, we have obtained accelerated approvalmust compete with them for clinical sites, physicians and the limited number of patients who fulfill the stringent requirements for participation in clinical trials. Also, due to market FOLOTYN, BELEODAQ and MARQIBO,the confidential nature of clinical trials, we are subject to
ongoing regulatory obligations and review, including completiondo not know how many of the post-approval requirements.

FOLOTYNeligible patients may be enrolled in competing studies and BELEODAQ were approvedwho are consequently not available to us for our clinical trials. Our clinical trials may be delayed or terminated due to the inability to enroll enough patients. Patient enrollment depends on many factors, including the size of the patient population, the nature of the trial protocol, the proximity of patients to clinical sites and the eligibility criteria for the treatmentstudy. The delay or inability to meet planned patient enrollment may result in increased costs and delays or termination of patients with relapsed or refractory PTCL, and MARQIBO was approved for the treatment of adult patients with Ph-ALL in second or greater relapse or whose disease has progressed following two or more anti-leukemia therapies, under the FDA’s accelerated approval regulations. These provisions allow the FDA to approve products for cancer or other serious or life threatening diseases basedtrial, which could have a harmful effect on initial positive data from clinical trials. Under these provisions, we are subject to certain post-approval requirements. Specifically, we are required to conduct Phase 1 dose escalating studies and a Phase 3 randomized study for FOLOTYN and BELEODAQ in patients with PTCL. The FDA also required that we conduct two Phase 1 trials to assess whether FOLOTYN poses a serious risk of altered drug levels resulting from organ impairment as well as additional post-marketing studies with BELEODAQ. For MARQIBO, we are required to conduct a randomized Phase 3 study in patients over 60 years of age with newly diagnosed ALL. Negative or inconclusive results in these additional trials could negatively impact, or preclude altogether, our ability to continue commercializing FOLOTYN, BELEODAQ OR MARQIBO. Failure to complete the studies or adhere to the timelines established by the FDA could result in penalties, including fines or withdrawal of FOLOTYN, BELEODAQ, and/or MARQIBO from the market, which could materially adversely affect our business.
The FDA may also initiate proceedings to withdraw approval or request that we voluntarily withdraw these drugs from the market if our Phase 3 studies fail to confirm clinical benefit. Further, the FDA may require us to amend the package inserts for these drugs, including by strengthening the warnings and precautions section or institute a REMS based on the results of these studies or clinical experience. Later discovery of previously unknown problems with our proposed products, including unanticipated clinical trial results or failure to comply with regulatory requirements, may result in restrictions on such products or manufacturing processes, withdrawal of the products from the market, voluntary or mandatory recall, fines, suspension of regulatory approvals, product seizures, injunctions or the imposition of civil or criminal penalties, which could materially adversely affect our business. We are also subject to additional, continuing post-approval regulatory obligations, including the possibility of additional clinical studies required by the FDA, safety reporting requirements and regulatory oversight of the promotion and marketing of these drugs.develop products.
We may have conflicts with our third-party development partners that could delay or prevent the development or commercialization of our drug products.
We may have conflicts with our third-party development partners, such as conflicts concerning the interpretation of pre-clinical or clinical data, the achievement of milestones, the interpretation of contractual obligations, payments for services,

Table of Contents


development obligations or the ownership of intellectual property developed during our collaboration. If any conflicts arise with any of our third-party development partners, such partner may act in a manner that is adverse to our best interests. Any such disagreement could result in one or more of the following, each of which could delay or prevent the development or commercialization of our drug product, and in turn prevent us from generating revenues from such drug product:
 
unwillingness on the part of a third-party development partner to pay us milestone payments or royalties that we believe are due to us under a collaboration;
uncertainty regarding ownership of intellectual property rights arising from our collaborative activities, which could prevent us from entering into additional collaborations;
unwillingness to cooperate in the manufacture of the product, including providing us with product data or materials;
unwillingness to keep us informed regarding the progress of its development and commercialization activities or to permit public disclosure of the results of those activities;
initiation of litigation or alternative dispute resolution options by either party to resolve the dispute;
attempts by either party to terminate the collaboration;
our ability to maintain or defend our intellectual property rights may be compromised by our partner’s acts or omissions;
a third-party development partner may utilize our intellectual property rights in such a way as to invite litigation that could jeopardize or invalidate our intellectual property rights or expose us to potential liability;
a third-party development partner may change the focus of its development and commercialization efforts due to internal reorganizations, mergers, consolidations or otherwise;
unwillingness to fully fund or commit sufficient resources to the testing, marketing, distribution or development of our products;
unwillingness or inability to fulfill their obligations to us due to the pursuit of alternative products, conflicts of interest that arise or changes in business strategy or other business issues; and/or
we may not be able to guarantee supplies of development or marketed products.

Given these risks, it is possible that any collaborative arrangements which we have or could enter into may not be successful.
From time to time we may need to in-license patents and proprietary technologies from third parties, which may be difficult or expensive to obtain.
We may need to obtain licenses to patents and other proprietary rights held by third parties to successfully develop, manufacture and market our drug products. As an example, it may be necessary to use a third party’s proprietary technology to reformulate one of our drug products in order to improve upon the capabilities of the drug product. If we are unable to timely obtain these licenses on reasonable terms, or at all, our ability to commercially exploit our drug products may be inhibited or prevented.
The potential size of the market for our drug products is uncertain.
We often provide estimates of the number of people who suffer from the diseases that our drugs are targeting. However, there is limited information available regarding the actual size of these patient populations. In addition, it is uncertain whether the results from previous or future clinical trials of drug products will be observed in broader patient populations, and the number of patients who may benefit from our drug products may be significantly smaller than the estimated patient populations.
Our collaboration partner, Mundipharma International Corporation Limited, or Mundipharma, may not be successful in obtaining regulatory approval for FOLOTYN in a number of countries and FOLOTYN is subject to numerous complex regulatory requirements.
Our collaboration partner, Mundipharma, may not be successful in obtaining regulatory approval for FOLOTYN in a number of countries and FOLOTYN is subject to numerous complex regulatory requirements. Failure to comply with, or

Table of Contents


changes to, the regulatory requirements that are applicable to FOLOTYN outside the U.S. may result in a variety of consequences, including the following:
restrictions on FOLOTYN or our manufacturing processes;
warning letters;
withdrawal of FOLOTYN from the market;
voluntary or mandatory recall of FOLOTYN;
fines against us;
suspension or withdrawal of regulatory approvals for FOLOTYN;
suspension or termination of any of our ongoing clinical trials of FOLOTYN;
refusal to permit import or export of FOLOTYN;
refusal to approve pending applications or supplements to approved applications that we submit;
denial of permission to file an application or supplement in a jurisdiction;
product seizure; and/or
injunctions, consent decrees, or the imposition of civil or criminal penalties against us.
The occurrence of one or more of the above-mentioned actions could have a material and adverse impact on our business, financial condition, results of operations and cash flows.
Changes in our effective income tax rate could adversely affect our profitability.
We are subject to federal and state income taxes in the U.S. and our tax liabilities are dependent upon the distribution of income among these different jurisdictions. Various factors may have favorable or unfavorable effects on our effective income tax rate. These factors include, but are not limited to:
interpretations of existing tax laws;
the accounting for stock options and other share-based compensation;
changes in tax laws and rates;
future levels of research and development spending;
changes in accounting standards;
changes in the mix of earnings in the various tax jurisdictions in which we operate;
the outcome of examinations by the Internal Revenue Service and tax regulators in other jurisdictions;
the accuracy of our estimates for unrecognized tax benefits;
realization of deferred tax assets; and
changes in overall levels of pre-tax earnings.
The impact on our income taxes resulting from the above-mentioned factors may be significant and could have an impact on our profitability.

Our sales and operations are subject to the risks of doing business internationally.
We have a presence in international markets subjecting us to many risks that could adversely affect our business and revenues, such as:
the inability to obtain necessary foreign regulatory or pricing approvals of products in a timely manner;
collectability of accounts receivable;
fluctuations in foreign currency exchange rates, in particular the recent strength of the U.S. dollar versus foreign currencies that has adversely impacted our revenues and net income;

34

Table of Contents


difficulties in staffing and managing international operations;
the imposition of governmental controls;
less favorable intellectual property or other applicable laws;
increasingly complex standards for complying with foreign laws and regulations that may differ substantially from country to country and may conflict with corresponding U.S. laws and regulations;
the far-reaching anti-bribery and anti-corruption legislation in the U.K., including the U.K. Bribery Act 2010, and elsewhere and escalation of investigations and prosecutions pursuant to such laws;
compliance with complex import and export control laws;
restrictions on direct investments by foreign entities and trade restrictions;
greater political or economic instability; and
changes in tax laws and tariffs.
Failure to comply with domestic or foreign laws applicable to our international operations could result in various adverse consequences, including: possible delay in approval or refusal to approve a product; recalls, seizures or withdrawal of an approved product from the market; disruption in the supply or availability of our products or suspension of export or import privileges; the imposition of civil or criminal sanctions; the prosecution of executives overseeing our international operations; and damage to our reputation. Any significant impairment of our ability to sell products outside of the U.S. could adversely impact our business and financial results.
If our employees, representatives or agents fail to comply with regulatory standards and requirements, we could be exposed to financial, reputational or other harm.
Our business and financial condition could be adversely affected to the extent that our employees, representatives or agents fail to:
comply with FDA regulations or similar regulations of similar regulatory authorities in other countries;
provide accurate information to the FDA or similar regulatory authorities in other countries;
comply with manufacturing standards we, the FDA or similar authorities in other countries have established;
comply with federal and state healthcare fraud and abuse laws and regulations or similar laws and regulations
established and enforced by comparable foreign regulatory authorities;
comply with the provisions of the Foreign Corrupt Practices Act, or the FCPA; or
report financial information or clinical or preclinical data accurately.
In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended 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, sales commission, customer incentive programs and other business arrangements. Misconduct by our employees, representatives or agents could also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. It is not always possible to identify and deter employee misconduct, and the precautions we take to detect and prevent these activities 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 be in compliance with such laws or regulations. If any such actions are instituted against us, even if we are ultimately exonerated, we could incur substantial costs and expenses in an effort to defend ourselves or to assert our rights and any such actions could result in reputational harm to us or have a significant impact on our business and results of operations, including the imposition of significant fines or other sanctions.
Earthquakes or other natural or man-made disasters and business interruptions could adversely affect our business.
Our operations are vulnerable to interruption by fire, power loss, floods, telecommunications failure and other events beyond our control. In addition, our operations are susceptible to disruption as a result of natural disasters such as earthquakes. So far we have never experienced any significant disruption of our operations as a result of earthquakes or other natural or

35

Table of Contents


man-made disasters. Although we have a contingency recovery plan, any significant business interruption could cause delays in our drug development and future sales and harm our business.
A breakdown or breach of our information technology systems and cybersecurity efforts could subject us to liability, reputational damage or interrupt the operation of our business.
We rely upon our sophisticated information technology systems and infrastructure to operate our business.  In the ordinary course of business, we collect, store and transmit large amounts of confidential information (including, but not limited to, personal information and intellectual property), and we deploy and operate an array of technical and procedural controls to maintain the confidentiality and integrity of such confidential information.  Data privacy breaches by those who access our systems, whether by employees or others, may pose a risk that sensitive data, including intellectual property, trade secrets or personal information belonging to us, our patients, employees, customers or other business partners, may be exposed to unauthorized persons or to the public or otherwise used for unauthorized purposes.We could also experience a business interruption, noncompliance with data privacy laws, theft of confidential information, or reputational damage from industrial espionage attacks, malware or other cyber-attacks, which may compromise our system infrastructure or lead to data leakage, either internally or at our third-party providers.  Such attacks are of ever-increasing levels of sophistication, frequency and intensity, and have become increasingly difficult to detect. There can be no assurance that our efforts to protect our data and information technology systems will prevent breakdowns or breaches in our systems (or that of our third-party providers). Any such interruption or breach of our systems or improper use of confidential data could adversely affect our business operations, financial condition, and/or result in the loss of critical or sensitive confidential information or intellectual property, and could result in financial, legal, business and reputational harm to us.
We have a history of net losses. We expect to continue to incur net losses and may not achieve profitability for some time, if at all.
We have incurred net losses in each of the years ended December 31, 2018, 2017,2021 and 2016, respectively.2020. We have incurred these losses principally from costs incurred in our research and development programs and from our selling, general and administrative expenses. We expect that in the foreseeable future we will continue to spend substantial amounts on research and development to further develop and potentially commercialize poziotinib and ROLONTIS.eflapegrastim. Accordingly, we expect to continue to incur net losses in the foreseeable future and may not achieve profitability for some time, if at all. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. If we are unable to achieve and sustain profitability, the market value of our common stock will likely decline.
Risks Related to Our Industry
If we are unable to adequately protect our technology or enforce our patent rights, our business could suffer.
Our success with the drug products that we develop will depend, in part, on our ability and the ability of our licensors to obtain and maintain patent protection for these products. We currently have a number of U.S. and foreign patents issued and pending, however, we primarily rely on patent rights licensed from others. Our license agreements generally give us the right and/or obligation to maintain and enforce the subject patents. We may not receive patents for any of our pending patent applications or any patent applications we may file in the future. If our pending andThe future patent applications are not allowed or, if allowed and issued into patents, if such patents and the patents we have licensed are not upheld in a court of law, our ability to competitively exploit our drug products would be substantially harmed. Also, such patents may or may not provide competitive advantages for their respective products or they may be challenged or circumvented by our competitors, in which case our ability to commercially exploit these products may be diminished.
The patent positions of pharmaceutical and biotechnology companies can be highly uncertain and involve complex legal and factual questions. No consistent policy regarding the breadth of claims allowed in pharmaceutical and biotechnology patents has emerged to date in the U.S. The laws of many countries may not protect intellectual property rights to the same extent as U.S. laws, and those countries may lack adequate rules and procedures for defending our intellectual property rights. Filing, prosecuting and defending patents on all our products or product candidates throughout the world would be prohibitively expensive. Competitors may use our technologies in jurisdictions not covered by any of our patent claims or other intellectual property rights.
Changes in either patent laws or in interpretations of patent laws in the U.S. and other countries may diminish the value of our intellectual property. We do not know whether any of our patent applications will result in the issuance of any patents, and we cannot predict the breadth of claims that may be allowed in our patent applications or in the patent applications we license from others.

The degree of future protection for our proprietary rights is uncertain because legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep our competitive advantage. For example:
in certain jurisdictions, we or our licensors might not have been the first to make the inventions covered by each of our or our licensors’ pending patent applications and issued patents, and we may have to participate in expensive and protracted interference proceedings to determine priority of invention;
we or our licensors might not have been the first to file patent applications for these inventions;
others may independently develop similar or alternative product candidates or duplicate any of our or our licensors’ product candidates;
our or our licensors’ pending patent applications may not result in issued patents;
our or our licensors’ issued patents may not provide a basis for commercially viable products or may not provide us with any competitive advantages or may be challenged by third parties;
others may design around our or our licensors’ patent claims to produce competitive products that fall outside the scope of our or our licensors’ patents;
we may not develop or in-license additional patentable proprietary technologies related to our product candidates; or
the patents of others may prevent us from marketing one or more of our product candidates for one or more indications that may be valuable to our business strategy.
An issued patent does not guarantee us the right to practice the patented technology or commercialize the patented product. Third parties may have blocking patents that could be used to prevent us from commercializing our patented products and practicing our patented technology. Patents issued to us and our licensors and those that may be issued in the future to us and our licensors may be challenged, invalidated or circumvented, which could limit our ability to prevent competitors from marketing related product candidates or could limit the length of the term of patent protection of our product candidates. Our competitors may independently develop similar technologies. In addition, because of the extensive time required for development, testing and regulatory review of a potential product, it is possible that, before any of our product 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 the patent.
We also rely on trade secret protection and contractual protections for our unpatented and proprietary drug compounds. Trade secrets are difficult to protect. While we enter into confidentiality agreements with our employees, consultants and others, these agreements may not successfully protect our trade secrets or other confidential and proprietary information. It is possible that these agreements will be breached, or that they will not be enforceable in every instance, and that we will not have adequate remedies for any such breach. Likewise, although we conduct periodic trade secret audits of certain partners, vendors and contract manufacturers, these trade secret audits may not protect our trade secrets or other confidential and proprietary information. It is possible that despite having certain trade secret audit security measures in place, trade secrets or other confidential and proprietary information may still be leaked or disclosed to a third party. It is also possible that our trade secrets will become known or independently developed by our competitors.
We also rely on trademarks to protect the names of our products. These trademarks may be challenged by others. If we enforce our trademarks against third parties, such enforcement proceedings may be expensive. Some of our trademarks, including ZEVALIN are owned by, or assignable to, our licensors and, upon expiration or termination of the applicable license agreements, we may no longer be able to use these trademarks. If we are unable to adequately protect our technology, trade secrets or proprietary know-how, or enforce our patents and trademarks, our business, financial condition and prospects could suffer.
Intellectual property rights are complex and uncertain and therefore may subject us to infringement claims.
The patent positions related to our drug products are inherently uncertain and involve complex legal and factual issues. We believe that there is significant litigation in the pharmaceutical and biotechnology industry regarding patent and other intellectual property rights. A patent does not provide the patent holder with freedom to operate in a way that infringes the patent rights of others. We may be accused of patent infringement at any time. The coverage of patents is subject to interpretation by the courts, and the interpretation is not always uniform. If we are sued for patent infringement, we would need to demonstrate that our products or methods do not infringe the patent claims of the relevant patent and/or that the patent claims are invalid or unenforceable, and we may not be able to do this. Proving invalidity, in particular, is difficult since it requires a showing of clear and convincing evidence to overcome the presumption of validity enjoyed by issued patents in the U.S.

Although we are not aware of any infringement by any of our drug products on the rights of any third party, there may be third party patents or other intellectual property rights, including trademarks and copyrights, relevant to our drug products of which we are not aware. Third parties may assert patent or other intellectual property infringement claims against us, or our licensors and collaborators, with products. Any claims that might be brought against us relating to infringement of patents may cause us to incur significant expenses and, if successfully asserted against us, may cause us to pay substantial damages and result in the loss of our use of the intellectual property that is critical to our business strategy.
In the event that we or our partners are found to infringe any valid claim of a patent held by a third party, we may, among other things, be required to:
pay damages, including up to treble damages and the other party’s attorneys’ fees, which may be substantial;
cease the development, manufacture, use and sale of our products that infringe the patent rights of others through a court-imposed sanction such as an injunction;
expend significant resources to redesign our products so they do not infringe others’ patent rights, which may notwill be possible;
discontinue manufacturing or other processes incorporating infringing technology; or
obtain licenses to the infringed intellectual property, which may not be available to us on acceptable terms, or at all.
Rapid bio-technological advancement may render our drug products obsolete before we are able to recover expenses incurred in connection with their development. As a result, some of our drug products may never become profitable.
The pharmaceutical industry is characterized by rapidly evolving biotechnology. Biotechnologies under development by other pharmaceutical companies could result in treatments for diseases and disorders for which we are developing our own treatments. Several other companies are engaged in the research and development of compounds that are similar to our efforts. A competitor could develop a new biotechnology, product or therapy that(and has better efficacy, a more favorable side-effect profile or is more cost-effective than one or more of our drug products and thereby cause our drug products to become commercially obsolete. Some of our drug products may become obsolete before we recover the expenses incurred in their development. As a result, such products may never become profitable.
Failure to obtain regulatory approval outside the U.S. will prevent us from marketing our product candidates abroad.
We intend to market certain of our existing and future product candidates in and outside of the U.S. In order to market our existing and future product candidates in the EU and many other foreign jurisdictions, we must obtain separate regulatory approvals according to the applicable domestic laws and regulations. We have had limited interactions with foreign regulatory authorities, and the approval procedures vary among countries and can involve additional testing, and the time required to obtain approval may differ from that required to obtain FDA approval. The foreign regulatory approval process may include all of the risks associated with obtaining FDA approval as well as other risks specific to the jurisdictions in which we may seek approval. Approval by the FDA does not guarantee approval by regulatory authorities in other countries, and approval by one or more foreign regulatory authorities does not necessarily ensure approval by regulatory authorities in other countries.

A failure or delay in obtaining regulatory approval in one country may have a negative effect on the regulatory approval process in others. We may not obtain foreign regulatory approvals on a timely basis, if at all. We may not be able to file for foreign regulatory approvals and may not receive necessary approvals to commercialize our existing and future product candidates in any market.
Competition for patients in conducting clinical trials may prevent or delay product development and strain our limited financial resources.
Many pharmaceutical companies are conducting clinical trials involving patients with the disease indications that our drug products target. As a result, we must compete with them for clinical sites, physicians and the limited number of patients who fulfill the stringent requirements for participation in clinical trials. Also, due to the confidential nature of clinical trials, we do not know how many of the eligible patients may be enrolled in competing studies and who are consequently not available to us for our clinical trials. Our clinical trials may be delayed or terminated due to the inability to enroll enough patients. Patient enrollment depends on many factors, including the size of the patient population, the nature of the trial protocol, the proximity of patients to clinical sites and the eligibility criteria for the study. The delay or inability to meet planned patient enrollment

may result in increased costs and delays or termination of the trial, which could have a harmful effect on our ability to develop products.
Even after we receive regulatory approval to market our drug products, the market may not be receptive to our drug products upon their commercial introduction, which would negatively impact our ability to achieve profitability.
Our drug products may not gain market acceptance among physicians, patients, healthcare payers and the medical community. The degree of market acceptance of any approved drug products will depend on a number of factors, including:
the effectiveness of the drug product;
the prevalence and severity of any side effects;
potential advantages or disadvantages over alternative treatments;
relative convenience and ease of administration;
the strength of marketing and distribution support;
the price of the drug product, both in absolute terms and relative to alternative treatments; and
sufficient third-party coverage and reimbursement.
If our drug products receive regulatory approval but do not achieve an adequate level of acceptance by physicians, healthcare payers and patients, we may not generate drug product revenues sufficient to attain profitability.
Guidelines and recommendations published by various organizations can reduce the use of our products.
Government agencies, such as the CMS, promulgate regulations, and issue guidelines, directly applicable to us and to our products. In addition, third parties such as professional societies, practice management groups, insurance carriers, physicians, private health/science foundations and organizations involved in various diseases from time to time may publish guidelines or recommendations to healthcare providers, administrators and payers, and patient communities. Recommendations may relate to such matters as utilization, dosage, route of administration and use of related therapies and coverage and reimbursement of our products by government and private payers. Third-party organizations like the above have in the past made recommendations about our products. Recommendations or guidelines that are followed by patients and healthcare providers could result in decreased utilization and/or dosage of our products, any of which could adversely affect our product sales and operating results materially.
The sale of our products ishistorically been) subject to regulatory approvals and our business is subject to extensive regulatory requirements, and ifrequirements. If we are unable to obtain regulatory approval for our product candidates, or if we fail to comply with governmental regulations, we will be limited in our ability to commercialize our products and product candidates and/or will be subject us to penalties.
We are not permitted to market or promote any of our product candidates before we receive regulatory approval from the FDA or comparable foreign regulatory authorities, and we may never receive such regulatory approval for any of our product

candidates. Obtaining regulatory approval of a new drug is an uncertain, lengthy and expensive process, and success is never guaranteed. Despite the time, resources and effort expended, failure can occur at any stage. During each stage, there is a substantial risk that we will encounter serious obstacles that will further delay us and add substantial expense, that we will develop a product with limited potential for commercial success, or that we will be forced to abandon a product in which we have invested substantial amounts of time and money.
These risks may include failure of the product candidate in preclinical studies, difficulty enrolling patients in clinical trials, clinical trial holds or other delays in completing clinical trials, delays in completing formulation and other testing and work necessary to support an application for regulatory approval, adverse reactions to the product candidate or other safety concerns, insufficient clinical trial data to support the safety or efficacy of the product candidate or to differentiate our product candidate from competitors, an inability to manufacture sufficient quantities of the product candidate for development or commercialization activities in a timely and cost-effective manner, and failure to obtain, or delays in obtaining, the required regulatory approvals for the product candidate or the facilities in which it is manufactured. In order to receive approval from the FDA for each product candidate, we must demonstrate that the new drug product is safe and effective for its intended use and that the manufacturing processes for the product candidate comply with the FDA’s cGMPs, which include requirements related to production processes, quality control and assurance, and recordkeeping. The FDA has substantial discretion in the approval process for human medicines.

The FDA and comparable agencies in foreign countries impose many requirements related to the drug development process through lengthy and rigorous clinical testing and data collection procedures, and other costly and time consuming compliance procedures. While we believe that we are currently in compliance with applicable FDA regulations, if we or our partners, the CROs or CMOs with which we have relationships, fail to comply with the regulations applicable to our clinical testing, the FDA may delay, suspend or cancel our clinical trials, or the FDA might not accept the test results. The FDA, an institutional review board, third party investigators, any comparable regulatory agency in another country, or we, may suspend clinical trials at any time if the trials expose subjects participating in such trials to unacceptable health risks. Further, human clinical testing may not show any current or future drug product to be safe and effective to the satisfaction of the FDA or comparable regulatory agencies, or the data derived from the clinical tests may be unsuitable for submission to the FDA or other regulatory agencies. Once we submit an application seeking approval to market a drug product, the FDA or other regulatory agencies may not issue their approvals on a timely basis, if at all. If we are delayed or fail to obtain these approvals, our business and prospects may be significantly damaged. In addition, any regulatory approvals that we receive for our future product candidates may also be subject to limitations on the indicated uses for which they may be marketed or contain requirements for potentially cost prohibitive post-marketing follow-up studies and surveillance to monitor the safety and efficacy of the product.
If we obtain regulatory approval for our drug products, we, our partners, our manufacturers, and other contract entities will continue to be subject to extensive requirements by a number of international, federal, state and local agencies. These regulations will impact many aspects of our operations, including testing, research and development, manufacturing, safety, effectiveness, labeling, storage, quality control, adverse event reporting, record keeping, approval, advertising and promotion of our future products. The FDA and foreign regulatory authorities strictly regulate the promotional claims that may be made about prescription products and our product labeling, advertising and promotion is subject to continuing regulatory review. Physicians may nevertheless prescribe our product to their patients in a manner that is inconsistent with the approved label, or that is off-label. The FDA and other regulatory agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and if we are found to have improperly promoted off-label uses we may be subject to significant sanctions, civil and criminal fines and injunctions prohibiting us from engaging in specified promotional conduct.

In addition, the Company iswe are subject to the federal False Claims Act, or the FCA, as well as the false claims laws of several states. The FCA prohibits any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government, or knowingly making, or causing to be made, a false statement to get a false claim paid. Suits filed under the FCA, known as "qui tam"“qui tam” actions, can be brought by any private individual on behalf of the government and such private individuals, commonly known as "whistleblowers,"“whistleblowers,” may share in any amounts paid by the entity to the government in fines or settlement. The filing of qui tam actions has caused a number of pharmaceutical, medical device and other healthcare companies to have to defend a FCA action. When an entity is determined to have violated the FCA, it may be required to pay up to three times the actual damages sustained by the government, plus civil penalties for each separate false claim. Various states also have enacted laws modeled after the federal FCA.

In order to comply with these laws, we have implemented a compliance program designed to identify, prevent and mitigate risk through the implementation of compliance policies and training systems. We cannot guarantee that our compliance program will be sufficient or effective, that our employees will comply with our policies, that our employees will notify us of any violation of our policies, that we will have the ability to take appropriate and timely corrective action in response to any
28

Table of Contents

such violation, or that we will make decisions and take actions that will necessarily limit or avoid liability for whistleblower claims that individuals, such as employees or former employees, may bring against us or that governmental authorities may prosecute against us based on information provided by individuals. If we are found to be in violation of any of the laws and regulations described above or other applicable state and federal healthcare laws, we may be subject to penalties, including civil and criminal penalties, damages, fines, disgorgement, contractual damages, reputational harm, imprisonment, diminished profits and future earnings, exclusion from government healthcare reimbursement programs such as Medicare and Medicaid, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, and/or the curtailment or restructuring of our operations, any of which could have a material adverse effect on our business, results of operations and growth prospects. Any action against us for violation of these laws or regulations, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. Moreover, achieving and sustaining compliance with applicable federal, state and foreign healthcare laws is costly and time-consuming for our management.
The discovery of previously unknown safety risks with drug products approvedFailure to go to market or onobtain regulatory approval outside the market may raise costs,U.S. will prevent us from marketing such products, or require usour product candidates abroad.

In addition, we have only licensed the market. The FDArights to develop and market our products in limited territories. Other companies can market and sell the same products in other parts of the world upon local regulatory approvals. If negative publicity is associated with our products or similar products sold by third parties in their territories, our own efforts to successfully market and sell our products in our territories may revisitbe adversely impacted.

Recommendations may relate to cease manufacturesuch matters as utilization, dosage, route of administration and marketinguse of the products at issue. Even prior to any formal regulatory action, we could voluntarily decide to cease the distributionrelated therapies and sale or recall anycoverage and reimbursement of our products if concerns about their safety or effectiveness develop.

The FDA has significant authority to take regulatory actionsby government and private payers. Third-party organizations like the above have in the event previously unknown safety riskspast made recommendations about our products. Recommendations or guidelines that are identified or if data suggest that our products may present a risk to safety. For example, the FDA may:
require sponsors of marketed products to conduct post-approval clinical studies to assess a known serious risk, signals of serious risk or to identify an unexpected serious risk;
mandate labeling changes to products, at any point in a product’s lifecycle, based on new safety information;followed by patients and
require sponsors to implement a REMS for a product which could include a medication guide, patient package insert, a communication plan to healthcare providers or other elements the FDA deems necessary to assure safe use of the drug (either prior to approval or post-approval as necessary).
Failure to comply with a REMS could result in significant civil monetary penalties decreased utilization and/or other administrative actions by the FDA. Further, regulatory agenciesdosage of our products, any of which could change existing, or promulgate new, regulations at any time which mayadversely affect our ability to obtain or maintain approval of our existing or future products or require significant additional costs to obtain or maintain such approvals.product sales and operating results materially.
Legislative or regulatory reform of the healthcare system and pharmaceutical industry related to pricing, coverage or reimbursement may hurt our ability to sell our products profitably or at all.
Our ability to commercialize any products successfully will depend in part on the availability of coverage and reimbursement from third-party payers such as government authorities, private health insurers, health maintenance organizations including pharmacy benefit managers and other health care-related organizations, in both the U.S. and foreign markets. Even if we succeed in bringing one or more products to market, the amount reimbursed for our products may be insufficient to allow us to compete effectively and could adversely affect our profitability. Coverage and reimbursement by governmental and other third-party payers may depend upon a number of factors, including a governmental or other third-party payer’s determination that use of a product includes but is not limited to:
a covered benefit under its health plan;
safe, effective and medically necessary;
appropriate for the specific patient;
cost-effective; and
neither experimental nor investigational.
Obtaining coverage and reimbursement approval for a product from each third-party and governmental payer is a time-consuming and costly process that could require us to provide supporting scientific, clinical and cost-effectiveness data for the use of our products to each payer. We may not be able to provide data sufficient to obtain coverage and adequate reimbursement.
In both the U.S. and certain foreign jurisdictions, there have been and may continue to be a number of legislative and regulatory proposals related to coverage and reimbursement that could impact our ability to sell our products profitably. The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, collectively referred to as the Healthcare Reform Law, was signed into law on March 30, 2010. The Healthcare Reform Law substantially changed the way healthcare is financed by both governmental and private insurers and significantly impacted the pharmaceutical industry. The Healthcare Reform Law included, among other things, an annual, nondeductible fee on any entity that manufactures or imports specified branded prescription drugs and biologic agents, revisions to the definition of “average manufacturer price” for reporting purposes, increases in the amount of rebates owed by drug manufacturers under the Medicaid Drug Rebate Program, expansion of the 340B drug discount program that mandates discounts to certain hospitals, community centers and other qualifying providers, and changes to affect the Medicare Part D coverage gap, or “donut hole.” The full effects of these provisions will become apparent as these laws are implemented and the CMS and other agencies issue

41

Table of Contents


applicable regulations or guidance as required by the Healthcare Reform Law. Moreover, in the coming years, additional changes could be made to governmental healthcare programs that could significantly impact the success of our products.

The high cost of pharmaceuticals continues to generate substantial government interest. It is possible that proposals will be adopted, or existing regulations that affect the coverage and reimbursement of pharmaceutical and other medical products may change, that may impact our products currently on the market and any of our products approved for marketing in the future. Cost control initiatives could decrease the price that we receive for any of our products or product candidates. In addition, third-party payers are increasingly challenging the price and cost-effectiveness of medical products and services. Significant uncertainty exists as to the coverage and reimbursement status of newly-approved pharmaceutical products. Future developments may require us to decrease the price that we charge for our products, thereby negatively affecting our financial results.

In some foreign countries, particularly in the EU, prescription drug pricing is subject to governmental control. Drug pricing may be made against a reference price set by the healthcare providers as a measure for healthcare cost containment. Pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product. If coverage and reimbursement of our products are unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels for the purpose of adoption of these products in the national health services in these jurisdictions, our profitability will likely be negatively affected.
If we market products in a manner that violates federal or state health care fraud and abuse laws, we may be subject to civil or criminal penalties, including exclusion from participation in government health care programs.
As a pharmaceutical company, even though we do not provide healthcare services or receive payments directly from or bill directly to Medicare, Medicaid or other third-party payers for our products, we are subject to certain federal and state healthcare laws and regulations pertaining to fraud and abuse applicable to our business. Violations of fraud and abuse laws may be punishable by criminal and/or civil sanctions, including fines and/or exclusion or suspension from federal and state health care programs such as Medicare and Medicaid and debarment from contracting with the U.S. government.
The laws that may affect our ability to operate include the federal health care program Anti-Kickback Statute, which prohibits, among other things, knowingly and willfully offering, paying, soliciting, or receiving remuneration to induce or in return for purchasing, leasing, ordering, or arranging for the purchase, lease or order of any health care item or service reimbursable under Medicare,
30

Table of Contents

Medicaid or other federally-financed health care programs. This statute applies to arrangements between pharmaceutical manufacturers and prescribers, purchasers and formulary managers. Although there are a number of statutory exceptions and regulatory safe harbors protecting certain common activities, the exceptions and safe harbors are drawn narrowly, and practices that involve remuneration intended to induce prescribing, purchases or recommendations may be subject to scrutiny if they do not qualify for an exception or safe harbor.
Pharmaceutical companies have been prosecuted under these laws for a variety of alleged promotional and marketing activities, such as providing free product to customers with the expectation that the customers would bill federal programs for the product; reporting to pricing services inflated average wholesale prices that were then used by federal programs to set reimbursement rates; engaging in off-label promotion that caused claims to be submitted to Medicaid for non-covered off-label uses; and submitting inflated best price information to the Medicaid Drug Rebate Program. Federal enforcement agencies have also recently scrutinized product and patient assistance programs, including manufacturer reimbursement support services as well as relationships with specialty pharmacies. If our past or present operations are found to be in violation of any of such laws or any other governmental regulations that may apply to us, we may be subject to penalties, including civil and criminal penalties, damages, fines, exclusion from federal health care programs and/or the curtailment or restructuring of our operations. Any penalties, damages, fines, curtailment, or restructuring of our operations could adversely affect our ability to operate our
business and our financial results. Any action against us for violation of these laws, even if we successfully defend against them, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business.
The Health Insurance Portability and Accountability Act of 1996 also created prohibitions against health care fraud and false statements relating to health care matters. The health care fraud statute prohibits knowingly and willfully executing a scheme to defraud any health care benefit program, including private payers. The false statements statute prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for health care benefits, items or services.
In addition, there has been a recent trend of increased federal and state regulation of payments made to physicians. The federal "Sunshine"“Sunshine” requirements pursuant to the Healthcare Reform LawPPACA imposed new requirements on (i) manufacturers of

42

Table of Contents


drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to report annually to CMS information related to payments or other “transfers of value” made to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors and teaching hospitals), and (ii) applicable manufacturers and GPOs to report annually to CMS ownership and investment interests held by physicians (as defined above) and their immediate family members and payments or other “transfers of value” to such physician owners and their immediate family members. Manufacturers were required to begin data collection on August 1, 2013 and to report such data to the government by March 31, 2014 and by the 90th calendar day of each year thereafter. Failure to submit the required information may result in civil monetary penalties of up an aggregate of $150,000 per year (and up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported in an annual submission, and may result in liability under other federal laws or regulations.

The majority of states also have statutes or regulations similar to these federal laws, which apply to items and services reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payer. In addition, some states have laws that require pharmaceutical companies to adopt comprehensive compliance programs. For example, under California law, pharmaceutical companies must comply with both the April 2003 Office of Inspector General Compliance Program Guidance for Pharmaceutical Manufacturers and the PhRMAPharmaceutical Research and Manufacturers of America (“PhRMA”) Code on Interactions with Healthcare Professionals, as amended. Certain states also mandate the tracking and reporting of gifts, compensation, and other remuneration paid by us to physicians and other health care providers. We have adopted and implemented a compliance program designed to comply with applicable federal, state and local requirements wherever we operate, including but not limited to the laws of the states of California and Nevada.

Although compliance programs can mitigate the risk of investigation and prosecution for violations of these laws, the risks cannot be entirely eliminated. Compliance with these laws and regulations is costly and materially affects our business. Among other effects, health care regulations substantially increase the time, difficulty and costs incurred in obtaining and maintaining approval to market newly developed and existing products. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. We expect compliance with these regulations to require significant technical expertise and capital investment to ensure the reasonable design and operation of an effective compliance program.
Because of the breadth of these laws and the narrowness of the safe harbors, it is possible that some of our business activities could be subject to challenge under one or more of such laws. The Healthcare Reform LawPPACA also made several important changes to the
31

Table of Contents

federal Anti-Kickback Statute, false claims laws, and health care fraud statute by weakening the intent requirement under the anti-kickback and health care fraud statutes that may make it easier for the government, or whistleblowers to charge such fraud and abuse violations. A person or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Health Care Reform Law 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 statutes. In addition, the Healthcare Reform LawPPACA increases penalties for fraud and abuse violations. If our past, present or future operations are found to be in violation of any of the laws described above or other similar governmental regulations to which we are subject, we may incur significant civil, criminal and administrative penalties, damages, fines, imprisonment, exclusion from government funded healthcare programs, such as Medicare and Medicaid, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and negatively impact our financial results.
We may be involved in additional lawsuits to defend or enforce our patents, which could be expensive, time-consuming and unsuccessful.
Competitors may infringe upon our patents. To counter infringement or unauthorized use, we may be required to file infringement claims, which can be expensive and time-consuming. In addition, in an infringement proceeding, a court may decide that one or more of our patents is not valid or is unenforceable, or may refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology in question. An adverse result in any litigation or defense proceedings could put one or more of our patents at risk of being invalidated, held unenforceable, or interpreted narrowly and could put our patent applications at risk of not issuing. 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.

Interference or derivation proceedings provoked by third parties or brought by the USPTO may be necessary to determine the priority of inventions with respect to our patents or patent applications. An unfavorable outcome could require us to cease using the related technology or to attempt to license rights to it from the prevailing party. Our business could be harmed if the prevailing party does not offer us a license on commercially reasonable terms. Litigation or interference proceedings may fail,

43

Table of Contents


even if successful, may result in substantial costs and distract our management and other employees. 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 U.S. or in Europe.
Furthermore, because of the substantial amount of discovery that could be 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. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on our stock price.
We may be subject to product liability claims, and may not have sufficient product liability insurance to cover any such claims, which may expose us to substantial liabilities.
We may be held liable if any product we or our partners develop causes injury or is found otherwise unsuitable during product testing, manufacturing, clinical trials, marketing or sale. Regardless of merit or eventual outcome, product liability claims could result in decreased demand for our product candidates, injury to our reputation, withdrawal of patients from our clinical trials, substantial monetary awards to trial participants and the inability to commercialize any products that we may develop. These claims might be made directly by consumers, health care providers, competing pharmaceutical companies or others selling or testing our products. Although we currently carry product liability insurance that we believe is adequate, it is possible that this coverage will be insufficient to protect us from future claims. Additionally, our insurance may not reimburse us or may not be sufficient to reimburse us for expenses or losses we may suffer. Moreover, if insurance coverage becomes more expensive, we may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses due to liability. Failure to maintain sufficient insurance coverage could have a material adverse effect on our business, prospects and results of operations if claims are made that exceed our coverage.
On occasion, juries have awarded large judgments in class action lawsuits for claims based on drugs that had unanticipated side effects. In addition, the pharmaceutical and biotechnology industries, in general, have been subject to significant medical malpractice litigation. A successful product liability claim or series of claims brought against us could harm our reputation and business and financial condition.
We could be adversely affected by violations of the FCPA and other worldwide anti-bribery laws.
The FCPA prohibits U.S. companies and their respective representatives from offering, promising, authorizing, or making improper payments to foreign officials for the purpose of obtaining or retaining business abroad. In many countries, the health care professionals we regularly interact with meet the definition of a foreign government official for purposes of the FCPA. We have policies and procedures in place to ensure that we comply with the FCPA and similar laws; however, there is no assurance that such policies and procedures will protect us against liability under the FCPA or related laws for actions taken by our employees and intermediaries with respect to our business. Failure to comply with the FCPA and related laws could disrupt our business and lead to criminal and civil penalties including fines, suspension of our ability to do business with the federal government and denial of government reimbursement of our products, which could result in a material adverse impact on our business, financial condition, results of operations and cash flows. We could also be adversely affected by any allegation that we violated such laws.
The use of hazardous materials, including radioactivePricing for pharmaceutical products has come under increasing scrutiny by governments, legislative bodies and biological materials,enforcement agencies. Changes in our research and development and commercial efforts imposes certain compliance costs on us and may subject us to liability for claims arising from the use or misuse of these materials.
Our research and development, manufacturing (including a radio labeling step for ZEVALIN) and administration of our drugs involves the controlled use of hazardous materials, including chemicals, radioactive and biological materials, such as radioactive isotopes. We are subject to federal, state, local and foreign environmental laws and regulations governing,that control drug pricing for government programs allow for negotiated pricing or limit product coverage, and reduced reimbursements may adversely impact our operating results and our business.
Many companies in our industry have received a governmental request for documents and information relating to drug pricing and patient assistance programs. We may become subject to similar requests, which would require us to incur significant expense and result in distraction for our management team. Additionally, to the extent there are findings, or even allegations, of improper conduct on the part of the Company or its employees, such findings or allegations could result in negative publicity or other negative actions that could harm our reputation; cause changes in our product pricing and distribution strategies; reduce demand for our approved products and/or reduce reimbursement of approved products, including by federal health care programs such as Medicare and Medicaid and state health care programs.
Further, the Bipartisan Budget Act of 2018 (BBA), among other matters,things, amended the handling, storage, useAffordable Care Act, effective January 1, 2019, to close the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole”. In December 2018, CMS published a final rule permitting further collections and disposalpayments to and from certain Affordable Care Act qualified health plans and health insurance issuers under the Affordable Care Act risk adjustment program in response to the outcome of these materialsfederal district court litigation regarding the method CMS uses to determine this risk adjustment. On June 17, 2021 the U.S. Supreme Court dismissed a challenge on procedural grounds that argued the Affordable Care Act is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. Thus, the Affordable Care Act will remain in effect in its current form. Further, prior to the U.S. Supreme Court ruling, on January 28, 2021, President Biden issued an executive order to initiate a special enrollment period for purposes of obtaining health insurance coverage through the Affordable Care Act marketplace. The executive order also instructs certain governmental agencies to review and some waste byproducts. We cannot completely eliminatereconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the riskAffordable Care Act. It is unclear how such challenges and the healthcare reform measures of contaminationthe Biden administration will impact the Affordable Care Act.

Further legislation or injury from these materials and weregulation could be held liablepassed that could harm our business, financial condition and results of operations. Other legislative changes have been proposed and adopted since the Affordable Care Act was enacted. For example, in August 2011, President Obama signed into law the Budget Control Act of 2011, which, among other things, created the Joint Select Committee on Deficit Reduction to recommend to Congress proposals in spending reductions. The Joint Select Committee on Deficit Reduction did not achieve a targeted deficit reduction of at least $1.2 trillion for any damages that result,fiscal years 2012 through 2021, triggering the legislation’s automatic reduction to several government programs. This includes aggregate reductions to Medicare payments to providers of up to 2% per fiscal year, which could exceed our financial resources. We currently maintain insurance coverage for injuries resulting from the hazardous materials we use; however, future claims may exceed the amount of our coverage. Also, we do not have insurance coverage for environmental cleanupwent into effect beginning on April 1, 2013 and removal. Currently the costs of complying with such federal, state, local and foreign environmental regulations are not significant, and consist primarily of waste disposal expenses.will stay in effect through 2031 unless additional Congressional action is taken. However, they could become expensive, and current or future environmental laws or regulations may impair our research, development, production and commercialization efforts.

the 2% Medicare sequester from May 1, 2020 through March 31, 2022. Under current legislation, the actual reduction in Medicare payments will vary from 1% in 2022 to up to 3% in the final fiscal year of this sequester. Additionally, on March 11, 2021, President Biden signed the American Rescue Plan Act of 2021 into law, which eliminates the statutory Medicaid drug rebate cap, currently set at 100% of a drug’s average manufacturer price, for single source and innovator multiple source drugs, beginning January 1, 2024. In January 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to several types of providers, including hospitals, imaging centers and cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years.


Additionally, there has been increasing legislative and enforcement interest in the United States with respect to specialty drug pricing practices. Specifically, there have been several recent U.S. Congressional inquiries and federal and state legislative activity designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs under Medicare, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs. At the federal level, the Trump administration used several means to propose or implement drug pricing reform, including through federal budget proposals, executive orders and policy initiatives. For example, on July 24, 2020 and September 13, 2020, the Trump administration announced several executive orders related to prescription drug pricing that attempt to implement several of the administration’s proposals. The FDA also released a final rule and guidance in September 2020, implementing a portion of the importation executive order providing pathways for states to build and submit importation plans for drugs from Canada. Further, on November 20, 2020, HHS finalized a regulation removing safe harbor protection for price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy benefit managers, unless the price reduction is required by law. The implementation of the rule has been delayed by the Biden administration from January 1, 2022 to January 1, 2023 in response to ongoing litigation. The rule also creates a new safe harbor for price reductions reflected at the point-of-sale, as well as a new safe harbor for certain fixed fee arrangements between pharmacy benefit managers and manufacturers, the implementation of which have also been delayed pending review by the Biden administration until January 1, 2023. On November 20, 2020, CMS issued an interim final rule implementing President Trump’s Most Favored Nation executive order, which would tie Medicare Part B payments for certain physician-administered drugs to the lowest price paid in other economically advanced countries. As a result of litigation challenging the Most Favored Nation model, on December 27, 2021, CMS published a final rule that rescinded the Most Favored Nation model interim final rule.

In July 2021, the Biden administration released an executive order, “Promoting Competition in the American Economy,” with multiple provisions aimed at prescription drugs. In response to Biden’s executive order, on September 9, 2021, HHS released a Comprehensive Plan for Addressing High Drug Prices that outlines principles for drug pricing reform and sets out a variety of potential legislative policies that Congress could pursue to advance these principles. No legislation or administrative actions have been finalized to implement these principles. In addition, Congress is considering drug pricing as part of other reform initiatives. Individual states in the United States have also become increasingly active in passing legislation and implementing regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.

We anticipate that these and other healthcare reform efforts will continue to result in additional downward pressure on coverage and the price that we receive for any approved product, and could seriously harm our business. Any reduction in reimbursement from Medicare and 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 products. Such reforms could have an adverse effect on anticipated revenue from product candidates that we may successfully develop and for which we may obtain regulatory approval and may affect our overall financial condition and ability to develop product candidates. Further, it is possible that additional governmental action will be taken in response to the COVID-19 pandemic.
Risks Related to Our Common Stock
Future issuances of our common stock or instruments convertible or exercisable into our common stock, may materially and adversely affect the price of our common stock and cause dilution to our existing stockholders.
We may obtain additional funds through public or private debt or equity financings in the near future. If we issue additional shares of common stock or instruments convertible into common stock, it may materially and adversely affect the price of our common stock. In the past, we have issued shares of common stock pursuant to at-the-market-issuance sales agreements and we may do so in the future. Certain issuances by us of equity securities may be at or below the prevailing market price of our common stock and may have a dilutive impact on our existing stockholders. In addition, future exercises of some or all of our outstanding options, warrants, or other rights may likewise dilute the ownership interests of our stockholders, and any sales in the public market of any shares of our common stock issuable upon such conversion or exercise, or the
33

Table of Contents

perception that such sales may occur, could adversely affect the prevailing market price of our common stock. These issuances or other dilutive issuances would also cause our per share net income, if any, to decrease in future periods.
The market price and trading volume of our common stock fluctuate significantly and could result in substantial losses for individual investors.
The stock market from time to time experiences significant price and trading volume fluctuations that are unrelated to the operating performance of particular companies. These broad market fluctuations may cause the market price and trading volume of our common stock to decrease. In addition, the market price and trading volume of our common stock is often highly volatile.
Factors that may cause the market price and volume of our common stock to decrease include, among other things:
the impact of COVID-19 on the U.S. and global economies;
adverse results or delays in our clinical trials, including as a result of COVID-19;
fluctuations in our results of operations;
timing and announcements of our technological innovations or new products or those of our competitors;
developments concerning any strategic alliances or acquisitions we may enter into;
announcements of FDA non-approval of our products, or delays in the FDA or other foreign regulatory review processes or actions, including the deferral of action on the BLA for eflapegrastim due to the inability to conduct an inspection of the manufacturing facility citing COVID-19 related travel restrictions;
changes in recommendations or guidelines of government agencies or other third parties regarding the use of our products;
adverse actions taken by regulatory agencies with respect to our drug products, clinical trials, manufacturing processes or sales and marketing activities;
concerns about our in-development products being reimbursed at requisite levels in the future;
any lawsuit involving us or our products;
developments with respect to our patents and proprietary rights;
public concern as to the safety of products developed by us or others;
regulatory developments in the U.S. and in foreign countries;
changes in stock market analyst recommendations regarding our common stock or lack of analyst coverage;
failure of our results of operations to meet the expectations of stock market analysts and investors;
sales of our common stock by our executive officers, directors and significant stockholders or sales of substantial amounts of our common stock generally; and
loss of any of our key scientific or management personnel.
Also, certain dilutive securities such as warrants can be used as hedging tools which may increase volatility in our stock and cause a price decline. While a decrease in market price could result in direct economic loss for an individual investor, low trading volume could limit an individual investor’s ability to sell our common stock, which could result in substantial economic loss as well. From January 1, 2021 through March 10, 2022, the closing price of our common stock ranged between $0.63 and $4.45, and the daily trading volume was as high as 36.5 million shares and as low as 0.8 million shares.
Following periods of volatility in the market price of a company’s securities, a securities class action litigation may be instituted against that company. Regardless of their merit, these types of lawsuits generally result in substantial legal fees and management’s attention and resources being diverted from the operations of a business.

We have not been in compliance with the requirements of the NASDAQ Stock Market for continued listing and if NASDAQ does not concur that we have adequately remedied our non-compliance, our common stock may be delisted from trading on NASDAQ, which could have a material adverse effect on us and our shareholders.

On March 10, 2022, we received notice from The NASDAQ Stock Market (“Nasdaq”) that, because the closing bid price for the Company's common stock has fallen below $1.00 per share for 30 consecutive business days, the Company no longer complies with the minimum bid price requirement for continued listing on the Nasdaq Global Market.

Nasdaq's notice has no immediate effect on the listing of the Company's common stock on the Nasdaq Global Market. Pursuant to Nasdaq Marketplace Rule 5810(c)(3)(A), the Company has been provided an initial compliance period of 180 calendar days, or until September 6, 2022, to regain compliance with the minimum bid price requirement. To regain compliance, the closing bid price of the Company's common stock must meet or exceed $1.00 per share for a minimum of 10 consecutive business days prior to September 6, 2022.
If the Company does not regain compliance by September 6, 2022, the Company may be eligible for an additional grace period if it applies to transfer the listing of its common stock to the Nasdaq Capital Market. To qualify, the Company would be required to meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for the Nasdaq Capital Market, with the exception of the minimum bid price requirement, and provide written notice of its intention to cure the minimum bid price deficiency during the second compliance period by effecting a reverse stock split if necessary. If the Nasdaq staff determines that the Company will not be able to cure the deficiency, or if the Company is otherwise not eligible for such additional compliance period, Nasdaq will provide notice that the Company's common stock will be subject to delisting. The Company would have the right to appeal a determination to delist its common stock, and the common stock would remain listed on the Nasdaq Global Market until the completion of the appeal process.
Provisions of our charter, and bylaws may make it more difficult for someone to acquire control of us or replace current management even if doing so would benefit our stockholders, which may lower the price an acquirer or investor would pay for our stock.
Provisions of our certificate of incorporation and bylaws, both as amended, may make it more difficult for someone to acquire control of us or replace our current management. These provisions include:
the ability of our Board of Directors to amend our bylaws without stockholder approval;
the inability of stockholders to call special meetings;
the ability of members of the Board of Directors to fill vacancies on the Board of Directors;
the inability of stockholders to act by written consent, unless such consent is unanimous; and
the establishment of advance notice requirements for the nomination of candidates for election to our Board of Directors or for proposing matters that can be acted on by stockholders at stockholder meetings.
These provisions may make it more difficult for stockholders to take certain corporate actions and could delay, discourage or prevent someone from acquiring our business or replacing our current management, even if doing so would benefit our stockholders. These provisions could limit the price that certain investors might be willing to pay for shares of our common stock.
Risks Relating to Our Intellectual Property
From time to time we may need to in-license patents and proprietary technologies from third parties, which may be difficult or expensive to obtain.
We may need to obtain licenses to patents and other proprietary rights held by third parties to successfully develop, manufacture and market our drug products. As an example, it may be necessary to use a third party’s proprietary technology to reformulate one of our drug products in order to improve upon the capabilities of the drug product. If we are unable to timely obtain these licenses on reasonable terms, or at all, our ability to commercially exploit our drug products may be inhibited or prevented.
If we are unable to adequately protect our technology or enforce our patent rights, our business could suffer.
Our success with the drug products that we develop will depend, in part, on our ability and the ability of our licensors to obtain and maintain patent protection for these products. We currently have a number of U.S. and foreign patents issued and pending, however, we primarily rely on patent rights licensed from others. Our license agreements generally give us the right and/or obligation to maintain and enforce the subject patents. We may not receive patents for any of our pending patent applications or any patent applications we may file in the future. If our pending and future patent applications are not allowed
35

Table of Contents

or, if allowed and issued into patents, if such patents and the patents we have licensed are not upheld in a court of law, our ability to competitively exploit our drug products would be substantially harmed. Also, such patents may or may not provide competitive advantages for their respective products or they may be challenged or circumvented by our competitors, in which case our ability to commercially exploit these products may be diminished.
The patent positions of pharmaceutical and biotechnology companies can be highly uncertain and involve complex legal and factual questions. No consistent policy regarding the breadth of claims allowed in pharmaceutical and biotechnology patents has emerged to date in the U.S. The laws of many countries may not protect intellectual property rights to the same extent as U.S. laws, and those countries may lack adequate rules and procedures for defending our intellectual property rights. Filing, prosecuting and defending patents on all our products or product candidates throughout the world would be prohibitively expensive. Competitors may use our technologies in jurisdictions not covered by any of our patent claims or other intellectual property rights.
Changes in either patent laws or in interpretations of patent laws in the U.S. and other countries may diminish the value of our intellectual property. We do not know whether any of our patent applications will result in the issuance of any patents, and we cannot predict the breadth of claims that may be allowed in our patent applications or in the patent applications we license from others.
Intellectual property rights do not necessarily address all potential threats.
The degree of future protection for our proprietary rights is uncertain because legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep our competitive advantage. For example:
in certain jurisdictions, we or our licensors might not have been the first to make the inventions covered by each of our or our licensors’ pending patent applications and issued patents, and we may have to participate in expensive and protracted interference proceedings to determine priority of invention;     
we or our licensors might not have been the first to file patent applications for these inventions;     
others may independently develop similar or alternative product candidates or duplicate any of our or our licensors’ product candidates;
our or our licensors’ pending patent applications may not result in issued patents;         
our or our licensors’ issued patents may not provide a basis for commercially viable products or may not provide us with any competitive advantages or may be challenged by third parties;     
others may design around our or our licensors’ patent claims to produce competitive products that fall outside the scope of our or our licensors’ patents;         
we may not develop or in-license additional patentable proprietary technologies related to our product candidates; or     
the patents of others may prevent us from marketing one or more of our product candidates for one or more indications that may be valuable to our business strategy.
An issued patent does not guarantee us the right to practice the patented technology or commercialize the patented product. Third parties may have blocking patents that could be used to prevent us from commercializing our patented products and practicing our patented technology. Patents issued to us and our licensors and those that may be issued in the future to us and our licensors may be challenged, invalidated or circumvented, which could limit our ability to prevent competitors from marketing related product candidates or could limit the length of the term of patent protection of our product candidates. Our competitors may independently develop similar technologies. In addition, because of the extensive time required for development, testing and regulatory review of a potential product, it is possible that, before any of our product 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 the patent.
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 lose intellectual property rights that are important to our business.
We are a party to exclusive license agreements with our partners and may need to obtain additional licenses from others to advance our research and development activities or allow the commercialization of our current product candidates and future product candidates we may identify and pursue. Our license agreements may impose, and we expect that future license agreements could impose various requirements on us, such as obligations related to development, diligence and commercialization, among others. In spite of our efforts, our licensors might conclude that we have materially breached our
36

Table of Contents

obligations under such license agreements and might therefore terminate the license agreements, thereby removing or limiting our ability to develop and commercialize products and technology covered by these license agreements. If these in-licenses are terminated, or if the underlying patents fail to provide the intended exclusivity, competitors or other third parties would have the freedom to seek regulatory approval of, and to market, products identical to ours and we may be required to cease our development and commercialization of our current product candidates or other product candidates that we may identify. Any of the foregoing could have a material adverse effect on our competitive position, business, financial conditions, results of operations, and prospects.
Moreover, disputes may arise regarding intellectual property subject to a licensing agreement, including:
the scope of rights granted under the license agreement and other interpretation-related issues;
the extent to which our product candidates, technology and processes infringe on intellectual property of the licensor that is not subject to the licensing agreement;
the sublicensing of patent and other rights under our collaborative development relationships;
our diligence obligations under the license agreement and what activities satisfy those diligence obligations;
the inventorship and ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and us and our partners; and
the priority of invention of patented technology.
In addition, the agreements under which we currently license intellectual property or technology from third parties are complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant intellectual property or technology, or increase what we believe to be our financial or other obligations under the relevant agreement, either of which could have a material adverse effect on our business, financial condition, results of operations, and prospects. Moreover, if disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on commercially acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates, which could have a material adverse effect on our business, financial conditions, results of operations, and prospects.
If we are unable to protect the confidentiality of our trade secrets, the value of our technology could be materially adversely affected and our business would be harmed.
We also rely on trade secret protection and contractual protections for our unpatented and proprietary drug compounds. Trade secrets are difficult to protect. While we enter into confidentiality agreements with our employees, consultants and others, these agreements may not successfully protect our trade secrets or other confidential and proprietary information. It is possible that these agreements will be breached, or that they will not be enforceable in every instance, and that we will not have adequate remedies for any such breach. Likewise, although we conduct periodic trade secret audits of certain partners, vendors and contract manufacturers, these trade secret audits may not protect our trade secrets or other confidential and proprietary information. It is possible that despite having certain trade secret audit security measures in place, trade secrets or other confidential and proprietary information may still be leaked or disclosed to a third party. It is also possible that our trade secrets will become known or independently developed by our competitors.
We also rely on trademarks to protect the names of our products. These trademarks may be challenged by others. If we enforce our trademarks against third parties, such enforcement proceedings may be expensive. Some of our trademarks are owned by, or assignable to, our licensors and, upon expiration or termination of the applicable license agreements, we may no longer be able to use these trademarks. If we are unable to adequately protect our technology, trade secrets or proprietary know-how, or enforce our patents and trademarks, our business, financial condition and prospects could suffer.
We may not be able to protect our intellectual property rights throughout the world.
Filing, prosecuting and defending patents on our product candidates in all countries throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the United States can be less extensive than those in the United States.
In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States. Consequently, we may not be able to prevent third parties from practicing our inventions in all
37

Table of Contents

countries outside the United States, or from selling or importing products made using our inventions in and into the United States or other jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and may also export infringing products to territories where we have patent protection, but enforcement is not as strong as that in the United States. These products may compete with our products and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.
Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets, and other intellectual property protection, particularly those relating to biotechnology products, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights generally. Proceedings to enforce our patent rights in foreign jurisdictions, whether or not successful, could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing and could provoke third parties to assert claims 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 or license.
Patent terms may be inadequate to protect our competitive position on our product candidates for an adequate amount of time.
Patents have a limited lifespan. In the United States, if all maintenance fees are timely paid, the natural expiration of a patent is generally 20 years from its earliest U.S. non-provisional filing date. Various extensions may be available, but the life of a patent, and the protection it affords, is limited. Even if patents covering our product candidates are obtained, once the patent life has expired, we may be open to competition from competitive products, including generics or biosimilars. Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.
Changes in U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our products.
Changes in either the patent laws or interpretation of the patent laws in the United States could increase the uncertainties and costs surrounding the prosecution of patent applications and the enforcement or defense of issued patents. Assuming that other requirements for patentability are met, prior to March 2013, in the United States, the first to invent the claimed invention was entitled to the patent, while outside the United States, the first to file a patent application was entitled to the patent. After March 2013, under the Leahy-Smith America Invents Act, or the America Invents Act, enacted in September 2011, the United States transitioned to a first inventor to file system in which, assuming that other requirements for patentability are met, the first inventor to file a patent application will be entitled to the patent on an invention regardless of whether a third party was the first to invent the claimed invention. A third party that files a patent application in the United States Patent and Trademark Office (“USPTO”) after March 2013, but before us could therefore be awarded a patent covering an invention of ours even if we had made the invention before it was made by such third party. This will require us to be cognizant of the time from invention to filing of a patent application. Since patent applications in the United States and most other countries are confidential for a period of time after filing or until issuance, we cannot be certain that we or our licensors were the first to either (i) file any patent application related to our product candidates or (ii) invent any of the inventions claimed in our or our licensor’s patents or patent applications.
The America Invents Act also includes a number of significant changes that affect the way patent applications will be prosecuted and also may affect patent litigation. These include allowing third party submission of prior art to the USPTO during patent prosecution and additional procedures to attack the validity of a patent by USPTO administered post-grant proceedings, including post-grant review, inter partes review, and derivation proceedings. Because of a lower evidentiary standard in USPTO proceedings compared to the evidentiary standard in United States federal courts necessary to invalidate a patent claim, a third party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a claim invalid even though the same evidence would be insufficient to invalidate the claim if first presented in a district court action. Accordingly, a third party may attempt to use the USPTO procedures to invalidate our patent claims that would not have been invalidated if first challenged by the third party as a defendant in a district court action. Therefore, the America Invents Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our owned or in-licensed patent applications and the enforcement or defense of our owned or in-licensed issued patents, all of which could have a material adverse effect on our business, financial condition, results of operations, and prospects.
38

Table of Contents

In addition, the patent positions of companies in the development and commercialization of pharmaceuticals are particularly uncertain. 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. This combination of events has created uncertainty with respect to the validity and enforceability of patents, once obtained. Depending on future actions by the U.S. Congress, the federal courts, and the USPTO, the laws and regulations governing patents could change in unpredictable ways that could have a material adverse effect on our existing patent portfolio and our ability to protect and enforce our intellectual property in the future.
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 non-compliance with these requirements.
Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and/or applications will be due to be paid to the USPTO and various governmental patent agencies outside of the United States in several stages over the lifetime of the patents and/or applications. We have systems in place to remind us when the fees are due, and we employ an outside firm to automatically pay these fees to both US and non-U.S agencies and we rely on our outside counsel to verify and confirm payment of these fees. 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. We employ reputable law firms and other professionals to help us comply, and in many cases, an inadvertent lapse can be cured by payment of a late fee or by other means in accordance with the applicable rules. However, there are situations in which non-compliance 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. In such an event, our competitors might be able to enter the market and this circumstance would have a material adverse effect on our business.
Intellectual property rights are complex and uncertain and therefore may subject us to infringement claims.
The patent positions related to our drug products are inherently uncertain and involve complex legal and factual issues. We believe that there is significant litigation in the pharmaceutical and biotechnology industry regarding patent and other intellectual property rights. A patent does not provide the patent holder with freedom to operate in a way that infringes the patent rights of others. We may be accused of patent infringement at any time. The coverage of patents is subject to interpretation by the courts, and the interpretation is not always uniform. If we are sued for patent infringement, we would need to demonstrate that our products or methods do not infringe the patent claims of the relevant patent and/or that the patent claims are invalid or unenforceable, and we may not be able to do this. Proving invalidity, in particular, is difficult since it requires a showing of clear and convincing evidence to overcome the presumption of validity enjoyed by issued patents in the U.S.
Although we are not aware of any infringement by any of our drug products of any valid patent rights of any third party, there may be third party patents or other intellectual property rights, including trademarks and copyrights, relevant to our drug products of which we are not aware. Third parties may assert patent or other intellectual property infringement claims against us, or our licensors and collaborators, with products. Any claims that might be brought against us relating to infringement of patents may cause us to incur significant expenses and, if successfully asserted against us, may cause us to pay substantial damages and result in the loss of our use of the intellectual property that is critical to our business strategy.
In the event that we or our partners are found to infringe any valid claim of a patent held by a third party, we may, among other things, be required to:
pay damages, including up to treble damages and the other party’s attorneys’ fees, which may be substantial;
cease the development, manufacture, use and sale of our products that infringe the patent rights of others through a court-imposed sanction such as an injunction;
expend significant resources to redesign our products so they do not infringe others’ patent rights, which may not be possible;
discontinue manufacturing or other processes incorporating infringing technology; or
obtain licenses to the infringed intellectual property, which may not be available to us on acceptable terms, or at all.
We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed confidential information of third parties or that our employees have wrongfully used or disclosed alleged trade secrets of their former employers.

As is common in the biotechnology and pharmaceutical industry, we employ individuals who were previously employed at universities or other biotechnology or pharmaceutical companies, including our competitors or potential competitors. Although we try to ensure that our employees, consultants and independent contractors 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 our employees, consultants or independent contractors have inadvertently or otherwise used or disclosed intellectual property, including trade secrets or other proprietary information, of any of our employee’s former employer or other third parties. Litigation may be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel, which could adversely impact 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.
In addition, while we require our employees and contractors who may be involved in the conception or 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, conceives or develops intellectual property that we regard as our own. The assignment of intellectual property rights may not be self-executing or the assignment agreements may be breached, and we may be forced to bring claims against third parties, or defend claims that they may bring against us, to determine the ownership of what we regard as our intellectual property.
We may be involved in additional lawsuits to defend or enforce our patents, which could be expensive, time-consuming and unsuccessful.
Competitors may infringe upon our patents. To counter infringement or unauthorized use, we may be required to file infringement claims, which can be expensive and time-consuming. In addition, in an infringement proceeding, a court may decide that one or more of our patents is not valid or is unenforceable, or may refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology in question. An adverse result in any litigation or defense proceedings could put one or more of our patents at risk of being invalidated, held unenforceable, or interpreted narrowly and could put our patent applications at risk of not issuing. 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.
Interference or derivation proceedings provoked by third parties or brought by the USPTO may be necessary to determine the priority of inventions with respect to our patents or patent applications. An unfavorable outcome could require us to cease using the related technology or to attempt to license rights to it from the prevailing party. Our business could be harmed if the prevailing party does not offer us a license on commercially reasonable terms. Litigation or interference proceedings may fail, even if successful, may result in substantial costs and distract our management and other employees. 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 U.S. or in Europe.
Furthermore, because of the substantial amount of discovery that could be 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. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on our stock price.
We may be subject to claims challenging the inventorship of our patents and other intellectual property.
We or our licensors may be subject to claims that former employees, collaborators or other third parties have an interest in our owned or in-licensed patents, trade secrets, or other intellectual property as an inventor or co-inventor. For example, we or our licensors may have inventorship disputes arise from conflicting obligations of employees, consultants or others who are involved in developing our product candidates. Litigation may be necessary to defend against these and other claims challenging inventorship or our or our licensors’ ownership of our owned or in-licensed patents, trade secrets or other intellectual property. If we or our licensors fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of, or right to use, intellectual property that is important to our product candidates. 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. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.
Some intellectual property that we have in-licensed may have been discovered through government funded programs and thus may be subject to federal regulations such as “march-in” rights, certain reporting requirements and a preference for U.S.-based companies. Compliance with such regulations may limit our exclusive rights, and limit our ability to contract with non-U.S. manufacturers.

Table of Contents

Some of the intellectual property rights we have licensed are generated through the use of U.S. government funding and are therefore subject to certain federal regulations. As a result, the U.S. government may have certain rights to intellectual property embodied in our current or future product candidates pursuant to the Bayh-Dole Act of 1980, or Bayh-Dole Act, and implementing regulations. These U.S. government rights in certain inventions developed under a government-funded program include a non-exclusive, non-transferable, irrevocable worldwide license to use inventions for any governmental purpose. In addition, the U.S. government has the right to require us or our licensors to grant exclusive, partially exclusive, or non-exclusive licenses to any of these inventions to a third party if it determines that: (i) adequate steps have not been taken to commercialize the invention; (ii) government action is necessary to meet public health or safety needs; or (iii) government action is necessary to meet requirements for public use under federal regulations (also referred to as “march-in rights”). The U.S. government also has the right to take title to these inventions if we, or the applicable licensor, fail to disclose the invention to the government and fail to file an application to register the intellectual property within specified time limits. These time limits have recently been changed by regulation, and may change in the future. Intellectual property generated under a government funded program is also subject to certain reporting requirements, compliance with which may require us or the applicable licensor to expend substantial resources. In addition, the U.S. government requires that any products embodying the subject invention or produced through the use of the subject invention be manufactured substantially in the United States. The manufacturing preference requirement can be waived if the owner of the intellectual property can show that reasonable but unsuccessful efforts have been made to grant licenses on similar terms to potential licensees that would be likely to manufacture substantially in the United States or that under the circumstances domestic manufacture is not commercially feasible. This preference for U.S. manufacturers may limit our ability to contract with non-U.S. product manufacturers for products covered by such intellectual property. To the extent any of our current or future intellectual property is generated through the use of U.S. government funding, the provisions of the Bayh-Dole Act may similarly apply.
Data breaches and cyber-attacks could compromise our intellectual property or other sensitive information and cause significant damage to our business, reputational harm and financial loss.
In the ordinary course of our business, we collect, maintain and transmit sensitive data on our networks and systems, including our intellectual property and proprietary or confidential business information (such as research data and personal information) and confidential information with respect to our customers, clinical trial patients and our business partners. We have also outsourced significant elements of our information technology infrastructure and, as a result, third parties may or could have access to our confidential information and personal data. The secure maintenance of this information is critical to our business and reputation. We believe that companies have been increasingly subject to a wide variety of security incidents, cyber-attacks and other attempts to gain unauthorized access and unintentional breaches. These threats can come from a variety of sources, ranging in sophistication from an individual hacker to a state-sponsored attack and motive (including corporate espionage). Cyber threats may be generic, or they may be custom-crafted against our information systems. Our network and storage applications and those of our vendors may be subject to unauthorized access by hackers or information security breaches due to operator error, malfeasance or other system disruptions. It is often difficult to anticipate or immediately detect such incidents and the damage caused by such incidents, particularly for cyber incidents such as advanced persistent threats. These data breaches and any unauthorized access or disclosure of our information or intellectual property could compromise our intellectual property and expose sensitive business information. A data security breach could also lead to public exposure of personal information of our clinical trial patients, customers and others. Cyber-attacks and information security breaches could cause us to incur significant remediation costs, result in product development delays, disrupt key business operations and divert attention of management and key information technology resources. Our network security and data recovery measures and those of our vendors may not be able to detect or prevent every attempted breach and may not permit us to respond effectively to every breach. These incidents could also subject us to liability, expose us to significant expense and cause significant harm to our reputation and business. Reputational harm resulting from a significant cyber incident may cause unquantifiable damage to our established goodwill. Moreover, as cyber incidents continue to evolve, we will likely be required to expend additional resources to enhance our security posture and cybersecurity defenses or to investigate and remediate any vulnerability to or consequences of cyber incidents. Our insurance coverage may not be sufficient to prevent or recover from cyberattacks, including coverage of applicable resulting losses arising from the incident.
Further, each foreign jurisdiction and U.S. state in which we operate may have laws governing how we must respond to a cyber incident that results in the unauthorized access, disclosure, or loss of personal information. Additionally, new laws and regulations governing data privacy and unauthorized disclosure of confidential information, including recent California legislation providing for a private right of action, pose increasingly complex compliance challenges and could potentially elevate our costs over time. As legislation continues to develop and cyber incidents continue to evolve, we will likely be required to expend significant resources to continue to modify or enhance our protective measures to comply with such legislation and to detect, investigate and remediate vulnerabilities to cyber incidents. Any failure by us to comply with such laws and regulations could result in reputational harm, loss of goodwill, penalties, liabilities and/or mandated changes in our business practices.

General Risk Factors
Our failure to establish and maintain effective internal control over financial reporting could result in material misstatements in our financial statements, our failure to meet our reporting obligations and cause investors to lose confidence in our reported financial information, which in turn could cause the trading price of our common stock to decline.
The results of our periodic management evaluations regarding the effectiveness of our internal control over financial reporting are required by the Sarbanes-Oxley Act of 2002. Any failure to maintain enhanced monitoring controls and improved detection and communication of financial misstatements across all levels of the organization could result in (i) material weaknesses, (ii) material misstatements in our financial statements, requiring restatements of our previously-filed financial statements, and (iii) cause us to fail to meet our timely reporting and debt compliance obligations. These outcomes could cause us to lose public confidence, and could cause the trading price of our common stock to decline. For further information regarding our controls and procedures, see Item 9A. Controls and Procedures.
Changes in our effective income tax rate could adversely affect our profitability. Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited.
We are subject to federal and state income taxes in the U.S. and our tax liabilities are dependent upon the distribution of income among these different jurisdictions. Various factors may have significant favorable or unfavorable effects on our effective income tax rate, and could have an impact on our profitability. These factors include, but are not limited to:
interpretations of existing tax laws;
the accounting for stock options and other share-based compensation;
changes in tax laws and rates;
future levels of research and development spending;
changes in accounting standards;
changes in the mix of earnings in the various tax jurisdictions in which we operate;
the outcome of examinations by the Internal Revenue Service and tax regulators in other jurisdictions;
the accuracy of our estimates for unrecognized tax benefits;
realization of deferred tax assets; and
changes in overall levels of pre-tax earnings.
Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, if a corporation undergoes an “ownership change” (generally defined as a greater than 50% change (by value) in its equity ownership over a three-year period), the corporation’s ability to use its pre-ownership change net operating loss carryforwards and other pre-ownership change tax attributes to offset its post-change income may be limited. As of December 31, 2018, an aggregate 5.0 million shares2021 we have U.S. net operating loss carryforwards of approximately $746.6 million. As a result of our public offerings of common stock, were issuable pursuantwe may have triggered an “ownership change.” We may also experience ownership changes in the future as a result of subsequent shifts in our stock ownership. Accordingly, if we earn net taxable income, our ability to use our pre-ownership change net operating loss carryforwards to offset U.S. federal taxable income may be subject to limitations, which could potentially result in increased future tax liability to us. If we become profitable in the exercisefuture, our ability to use net operating loss carryforwards and other tax attributes to offset future taxable income or reduce taxes may be subject to limitations, and we cannot assure what, if any, the benefit related to our net operating loss carryforwards will be in the future.
Natural disasters, war and other events could adversely affect our future revenues and operating income.
Natural disasters, including the impacts of outstanding optionsclimate change, hurricanes, tornadoes, windstorms, fires, earthquakes and floods and other extreme weather events, global health pandemics, war, terrorism, labor disruptions and international conflicts, and actions taken by the vestingUnited States and other governments or by our customers or suppliers in response to such events, could cause significant economic disruption and political and social instability in the United States and areas outside of restricted stock awardsthe United States in which we operate. These events could result in decreased demand for our products, adversely affect our manufacturing and units. Further, 17.6 million sharesdistribution capabilities, or increase the costs for or cause interruptions in the supply of common stock were reserved for future issuance undermaterials from our equity compensation plans.suppliers.

We are subject to the risks of securities and related litigation, which may expose us to substantial liabilities and could seriously harm our business.

We may be subject to the risk of securities litigation and derivative actions from time to time as a result of being publicly traded, including the remaining unresolved actions set forth in “ItemItem 3. Legal Proceedings.”Proceedings. There can be no assurance that any settlement or liabilities in such actions or any future lawsuits or claims against us would be covered or partially covered by our insurance policies, which could have a material adverse effect on our earnings in one or more periods. While we and our Board of Directors deny the allegations of wrongdoing against us in the unresolved actions initiated against us, there can be no assurance as to the ultimate outcome or timing of their resolutions. In addition to the potential costs and liabilities, securities litigation could divert management’s attention and resources, which could seriously harm our business.
TheGlobal, market price and trading volumeeconomic conditions may negatively impact our business, financial condition and share price.

Concerns over inflation, geopolitical issues, the U.S. financial markets, foreign exchange rates, capital and exchange controls, unstable global credit markets and financial conditions and the COVID-19 pandemic, have led to periods of significant economic instability, declines in consumer confidence and discretionary spending, diminished expectations for the global economy and expectations of slower global economic growth going forward, and increased unemployment rates. Our general business strategy may be adversely affected by any such economic downturns, volatile business environments and continued unstable or unpredictable economic and market conditions. If these conditions continue to deteriorate or do not improve, it may make any necessary debt or equity financing more difficult to complete, more costly and more dilutive. In addition, there is a risk that one or more of our common stock fluctuate significantlycurrent or future service providers, manufacturers, suppliers and other partners could result in substantial losses for individual investors.be negatively affected by difficult economic times, which could adversely affect our ability to attain our operating goals on schedule and on budget or meet our business and financial objectives.
The stock market from time to time experiences significant price and trading volume fluctuations that are unrelated to the operating performance of particular companies. These broad market fluctuations may cause the market price and trading volume of our common stock to decrease.
In addition, the market pricewe face several risks associated with international business and trading volumeare subject to global events beyond our control, including war, public health crises, such as pandemics and epidemics, trade disputes, economic sanctions, trade wars and their collateral impacts and other international events. Any of these changes could have a material adverse effect on our common stock is often highly volatile.
Factors that may cause the market price and volume of our common stock to decrease include, among other things:
recognition on up-front licensingreputation, business, financial condition or other fees or revenues;
payments of non-refundable up-front or license fees, or payment for cost-sharing expenses, to third parties;
adverse results or delays in our clinical trials;
fluctuations in our results of operations;

Also, certain dilutive securities such as warrants can be used as hedging tools which may increase volatility in our stock and cause a price decline. While a decrease in market price could result in direct economic loss for an individual investor, low trading volume could limit an individual investor’s ability to sell our common stock, which could result in substantial economic loss as well. From January 2, 2018 through February 21, 2019, the closing price of our common stock ranged between $6.39 and $24.82, and the daily trading volume was as high as 12.4 million shares and as low as 0.5 million shares.
Following periods of volatility in the market price of a company’s securities, a securities class action litigation may be instituted against that company. Regardless of their merit, these types of lawsuits generally result in substantial legal fees and management’s attention and resources being diverted from the operations of a business.
Provisions of our charter, and bylaws may make it more difficult for someone to acquire control of us or replace current management even if doing so would benefit our stockholders, which may lower the price an acquirer or investor would pay for our stock.
Provisions of our certificate of incorporation and bylaws, both as amended, may make it more difficult for someone to acquire control of us or replace our current management. These provisions include:
the ability of our Board of Directors to amend our bylaws without stockholder approval;
the inability of stockholders to call special meetings;
the ability of members of the Board of Directors to fill vacancies on the Board of Directors;
the inability of stockholders to act by written consent, unless such consent is unanimous; and
the establishment of advance notice requirements for the nomination of candidates for election to our Board of Directors or for proposing matters that can be acted on by stockholders at stockholder meetings.
These provisions may make it more difficult for stockholders to take certain corporate actions and could delay, discourage or prevent someone from acquiring our business or replacing our current management, even if doing so would benefit our stockholders. These provisions could limit the price that certain investors might be willing to pay for shares of our common stock.
Our failure to establish and maintain effective internal control over financial reporting could result in material misstatements in our financial statements, our failure to meet our reporting obligations and cause investors to lose confidence in our reported financial information, which in turn could cause the trading price of our common stock to decline.
The results of our periodic management evaluations and annual auditor attestation reports regarding the effectiveness of our internal control over financial reporting are required by the Sarbanes-Oxley Act of 2002. Any failure to maintain enhanced monitoring controls and improved detection and communication of financial misstatements across all levels of the organization could result in (i) material weaknesses, (ii) material misstatements in our financial statements, requiring restatements of our previously-filed financial statements, and (iii) cause us to fail to meet our timely reporting and debt compliance obligations.

ITEMItem 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSManagement’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion and analysis should be read in conjunction with “Selected Financial Data” and our consolidated financial statements and the related notes included in this Annual Report on Form 10-K. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result of various factors including the risks we discuss in Item 1A. Risk Factors and elsewhere in this Annual Report on Form 10-K.
OVERVIEWImpact of COVID-19 Pandemic
Our BusinessOn March 11, 2020, COVID-19 was declared a pandemic by the World Health Organization. Concerns related to the spread of COVID-19 have created global business disruptions as well as disruptions in our operations. The ongoing COVID-19 pandemic has adversely impacted economic activity and conditions worldwide, including workforces, liquidity, capital markets, consumer behavior, supply chains, and macroeconomic conditions. Despite progress in vaccination efforts, global economic activity remains uncertain and cannot be predicted with confidence. Further, in the first half of 2021, a new Delta variant of COVID-19 began to spread globally and caused an increase in COVID-19 cases in many places in the United States, and in

November 2021, a new Omicron variant, which appears to be the most transmissible variant to date, was detected, and has since caused an increase in COVID-19 cases in multiple countries, including the United States, and of which the potential severity is currently being evaluated.
Public health officials and medical professionals have warned that COVID-19 cases may continue to spike due to the Delta variant and/or the Omicron variant, particularly if vaccination rates do not quickly increase or if additional, potent disease variants emerge. It is unclear how long the resurgence due to Delta or the resurgence due to Omicron will last, how severe the Delta resurgence or Omicron resurgence will be, and what safety measures governments will impose in response to the Delta resurgence or Omicron resurgence. The impact of the Delta variant and the Omicron variant cannot be predicted at this time, and could depend on numerous factors, including vaccination rates among the population, the effectiveness of COVID-19 vaccines against the Delta variant and the Omicron variant and the response by governmental bodies and regulators. The outbreak has and may continue to affect the Company’s operations and those of third parties on which the Company relies. The degree and duration of COVID-19’s impact on our business, our operations, and the global economy as a whole, are unknown at this time. However, the effects could have a biopharmamaterial impact on our results of operations, and we will continue to monitor the situation closely.
The extent to which the COVID-19 pandemic may continue to impact our results of operations, including the long-term nature of the impacts, depends on numerous evolving factors, which are highly uncertain and difficult to predict, including the adoption rate of the COVID-19 vaccines, the emergence and spread of variants (including the Delta variant, a rapidly spreading strain of coronavirus), the scope and the timing to further contain the virus or treat its impact, and to what extent normal economic and operating conditions can resume, among others. For more information related to the impact of COVID-19 on our business, refer to the risk factors included in Item 1A. of this Annual Report on Form 10-K.

Our product pipeline is summarized below:
Eflapegrastim, a novel long-acting G-CSF:
We submitted our BLA for eflapegrastim to the year ended December 31, 2018FDA on October 24, 2019 that is supported by data from two similarly designed Phase 3 clinical trials, ADVANCE and RECOVER, which evaluated the safety and efficacy of eflapegrastim in 643 early-stage breast cancer patients for the treatment of neutropenia due to myelosuppressive chemotherapy. Both studies met the pre-specified endpoint of non-inferiority in duration of severe neutropenia and met all of the secondary endpoints. In addition, the safety profile was similar to pegfilgrastim. On August 6, 2021, we announced the receipt of a CRL based on manufacturing deficiencies identified at both the drug substance and drug product manufacturers. The company believes these manufacturing deficiencies have been remediated and on March 11, 2022, we resubmitted the BLA for eflapegrastim.
A company sponsored clinical trial has been initiated to evaluate the administration of eflapegrastim on the same day as chemotherapy. This Phase 1 clinical trial is a randomized, open label, actively controlled study to evaluate the same-day dosing of eflapegrastim on duration of neutropenia when administered at varying intervals following docetaxel and cyclophosphamide (TC) chemotherapy in patients with early-stage breast cancer. On March 4, 2021, at the virtual 38th Annual Miami Breast Cancer Conference®, the Company presented positive early data showing rapid absolute neutrophil count (ANC) recovery in the first three patients dosed in the 30-minute arm of the same-day dosing. This arm met the prespecified interim safety evaluation criteria and therefore supported the expansion of this arm to 15 patients. The study design included an interim safety evaluation that was conducted once the first three patients in each arm (30 minutes, 3 hours, or 5 hours) completed Cycle 1. Based on this review, the 30-minute arm expanded to a total of 15 patients, while the 3- and 5-hour dosing arms have been discontinued. In the 30-minute dosing arm, ANC recovery was more rapid compared to the 3- and 5-hour arms. The overall safety profile for the 30-minute arm was similar to what has been seen previously in large randomized studies with G-CSF given 24 hours after chemotherapy.
Poziotinib, a Pan ErbB inhibitor targeting HER2 exon20 mutations:
Poziotinib is a novel, pan-HER inhibitor that irreversibly blocks signaling through the filing dateEpidermal Growth Factor Receptor (EGFR) family of this Annual Report on Form 10-K, we madetyrosine-kinase receptors, including HER1 (erbB1; EGFR), HER2 (erbB2), HER4 (erbB4), and HER receptor mutations. This, in turn, leads to the inhibition of the proliferation of tumor cells that over-express these receptors. Mutations of over-expression/amplification of EGFR family receptors have been associated with a strategic shift in our business through executing an agreement to sell the distribution rights to our legacy commercialized drug portfolio. We also continued to make meaningful progress in the advancementnumber of our product pipeline, as summarized below:

Execution of Asset Purchase Agreement for our Commercialized Drug Portfolio:

On January 17, 2019,different cancers, including NSCLC, breast cancer, and gastric cancer. In March 2015, we entered into a definitive asset purchaseco-development and commercialization agreement with Hanmi for poziotinib worldwide rights, except in Korea and China.

Our clinical development program for poziotinib is focused on previously treated NSCLC, first-line treatment of NSCLC and treatment of other solid tumors with HER2 mutations. NSCLC tumors with HER2 exon 20 insertion mutations are rare and have generally not been responsive to other tyrosine kinase inhibitors. Patients with these mutations have a poor prognosis, and available treatment options are limited. Poziotinib, due to its unique chemical structure and characteristics, is believed to inhibit cell growth of tumors with HER2 exon-20 insertion mutations.

In October 2017, we announced the salestart of our FDA-approved product portfolio of FUSILEV, KHAPZORY, FOLOTYN, ZEVALIN, MARQIBO, BELEODAQ, and EVOMELA to Acrotech. Upon the closing of the Acrotech Transaction, we are entitled to receive up to $160 million in an upfront cash payment (of which $4 million will be held in escrow for six months). In addition, we expect a purchase price adjustment for certain ongoing research and development activities of the commercialized product portfolio. We are also entitled to receive an aggregate $140 million upon Acrotech's achievement of certain regulatory and sales-based milestones relating to this product portfolio. We plan to reduce our staff by approximately 90 employees, the majority of which we expect to transition to Acrotech.


Poziotinib, an irreversible tyrosine kinase inhibitor:

In September 2018, we announced preliminary poziotinib data from the University of Texas, MD Anderson Cancer Center ("MD Anderson")pivotal ZENITH20 Phase 2 non-small cell lung cancer ("NSCLC") study which were released during an oral presentation atglobal clinical trial with active sites in the IASLC 19th World Conference on Lung Cancer.U.S., Canada and Europe. The MD Anderson study is the single largest data setZENITH20 trial consists of seven cohorts of NSCLC patients. Cohorts 1, 2, 3 and 4 have completed enrollment while Cohorts 5, 6, and 7 are currently enrolling patients. Cohorts 1 (EGFR) and 2 (HER2) include previously treated NSCLC patients with an exon 20 mutationmutations. Cohort 3 (EGFR) and 4 (HER2) include first-line NSCLC patients with exon 20 mutations. Cohorts 1- 4 are each independently powered for a pre-specified statistical hypothesis and the primary endpoint is overall response rate (“ORR”). Cohort 5 includes previously treated or treatment-naïve NSCLC patients with EGFR or HER2 exon 20 insertion mutations and is evaluating different dosing regimens. Cohort 6 includes NSCLC patients with classical EGFR mutations who progressed while on treatment with first-line osimertinib and developed an additional EGFR mutation. Cohort 7 includes NSCLC patients with a variety of less common mutations in EGFR or HER2.  This Phase 2 study demonstrated high anti-tumor activity for poziotinib in metastatic, heavily pretreated EGFR exon 20 mutant NSCLC, a group for which no targeted agents have proved to be effective to date. This data is summarized below:
In 44 evaluable patients with EGFR exon-20 mutations,HER2 exons 18-21 or the confirmed overall response rate (ORR) was 43% and disease control rate was 90%. Median progression free survival (PFS) was 5.5 months (ITT).
In evaluable patients with HER2 exon-20 mutations, the confirmed overall response rate (ORR) was 42% and disease control rate was 83%. Median progression free survival (PFS) was 5.1 months (ITT).
EGFR-related toxicities (including rash, diarrhea, and paronychia) were manageable and required dose reductions in 60% of patients. Discontinuation due to poor tolerance was rare (approximately 3% of patients).

extracellular or transmembrane domains.
On January 2,December 26, 2019, we announced full enrollmentthat the pre-specified primary endpoint was not met in Cohort 1 of cohort 1 (N=87) forthe ZENITH20 trial evaluating poziotinib in previously treated NSCLC patients with EGFR exon 20 insertion mutationsmutations. Cohort 1 enrolled a total of 115 patients who received 16 mg/day of poziotinib. The intent-to-treat analysis showed that 17 patients had a response (by RECIST) and 62 patients had stable disease for a 68.7% disease control rate (“DCR”). The confirmed ORR was 14.8% (95% CI 8.9%-22.6%). The median duration of response was 7.4 months and the progression free survival was 4.2 months. The safety profile was in-line with sites acrossother second-generation EGFR tyrosine kinase inhibitors.
On July 27, 2020, we announced that we met the U.S., Europe, and Canada. The EGFR previously treated cohort is part ofpre-specified primary endpoint for Cohort 2 in the ZENITH20 trial - an open-label, multi-center, global Phase 2 trial evaluating previously treated NSCLC patients with EGFR or HER2 exon 20 insertion mutations. Results from this cohort are expected to be released during the second halfCohort 2 enrolled a total of 2019.

The intent-to-treat analysis demonstrated a confirmed ORR of 27.8% (95% CI of 18.9%-38.2%). Based on the pre-specified statistical hypothesis for the primary endpoint, the observed lower bound of 18.9% exceeded the pre-specified lower bound of 17% in this heavily pre-treated population. The safety profile was in-line with the type of adverse events seen with other second-generation EGFR tyrosine kinase inhibitors. These results were presented at the European Society for Medical Oncology (“ESMO”) Virtual Congress 2020 Science Weekend held in September 2020.
In February 2018December 2020, we reported that its pre-specified primary endpoint in Cohort 3 evaluating poziotinib in first-line NSCLC patients with EGFR exon 20 insertion mutations was not met. Cohort 3 of the ZENITH20 clinical trial enrolled a total of 79 patients who received an oral once daily dose of 16 mg of poziotinib. The median time of follow up of all patients was 9.2 months with 12 ongoing patients still on treatment. The intent-to-treat analysis showed that 22 patients had a partial response (by RECIST) and June 2018,68 patients had stable disease for an 86.1% DCR. 91% of patients experienced tumor reduction with a median reduction of 25.5%. The confirmed ORR was 27.8% (95% CI 18.4-39.1%). Based on the pre-specified statistical hypothesis for the primary endpoint, the observed lower bound of 18.4% did not meet the pre-specified lower bound of >20%. The median duration of response was 6.5 months and the median progression free survival was 7.2 months. The safety profile was similar with the type of adverse events observed with other second-generation EGFR tyrosine kinase inhibitors. Grade 3 treatment related rash was 33% and diarrhea was 23%. 94% of patients had drug interruptions with 6 patients (8%) permanently discontinuing due to adverse events.
In March 2021, we announced that the top lineFDA granted Fast Track designation for poziotinib based on data from Cohort 2 of ZENITH20, which evaluated previously treated patients with NSCLC with HER2 exon 20 insertion mutations. On December 6, 2021, the Company announced the submission of its NDA for poziotinib to the FDA for use in patients with previously treated locally advanced or metastatic NSCLC with HER2 exon 20 insertion mutations. The NDA submission is based on the positive results of our pivotal PhaseCohort 2 from the ZENITH20 clinical trial, which assessed the safety and efficacy of poziotinib. On February 11, 2022, the Company announced that the file had been accepted and an action date of November 24, 2022 had been set.
In March 2022, the Company presented the results of Cohort 4 at the ESMO TAT meeting. Cohort 4 of the ZENITH20 clinical trial enrolled a total of 70 patients, 48 of whom received an oral once daily dose of 16 mg of poziotinib and 22 of who received an oral twice daily dose of 8 mg of poziotinib. The intent-to-treat analysis demonstrated a confirmed ORR of 41% (95% CI of 30%-54%). Based on the pre-specified statistical hypothesis for the primary endpoint, the observed lower bound of 30% exceeded the pre-specified lower bound of 20%. The median duration of response was 5.7 months and median progression free survival was 5.6 months. The most common treatment related Grade ≥ 3 studies (ADVANCEadverse events were rash (30%), stomatitis (19%), diarrhea (14%), and RECOVER) demonstrated that itparonychia (7%). In addition, the incidence of Grade ≥ 3 pneumonitis was non-inferior to the current standard of care, and had a similarlow at 3%. The safety profile.

BLA Submission

We submitted our Biologics License Application ("BLA")profile was consistent with the FDA in late December 2018. Due to the recent federal government shutdown, the BLA was officially received by the FDA on January 28, 2019. Once this BLA is accepted by the FDA, our Prescription Drug User Fee Act date is expected to be set for 10 months thereafter.TKI class.

Liquidity and Capital Resources
We believe that our $100.6 million in aggregate cash, cash equivalents, and marketable securities as of December 31, 2021 combined with $20 million of equity financing received from Hanmi in January 2022 is sufficient to fund our current and planned operations for at least the next twelve months. We may, however, require additional liquidity as we continue to execute our business strategy, and in connection with opportunistic acquisitions or licensing arrangements. We anticipate that to the extent that we require additional liquidity, it will be funded through additional equity or debt financings, or out-licensing arrangements. However, we cannot provide assurance that we will be able to obtain this additional liquidity on terms favorable to us or our current stockholders, if at all. Additionally, our liquidity and our ability to fund our capital requirements are also dependent on our future financial performance which is subject to various market and economic factors that are beyond our control.
We have no off-balance sheet arrangements that provide financing, liquidity, market or credit risk support, or involve derivatives. In addition, we have no arrangements that may expose us to liability that are not expressly reflected in the accompanying Consolidated Financial Statements and/or notes thereto.
Net Cash Used In Operating Activities
Net cash used in operating activities was $119.5 million for the year ended December 31, 2021, as compared to $121.6 million for the year ended December 31, 2020. This slight decrease in net cash used in operating activities was primarily related to changes in working capital during the year ended December 31, 2021.
Net Cash Provided By Investing Activities
Net cash provided by investing activities was $108.7 million for the year ended December 31, 2021, as compared to $18.1 million for the year ended December 31, 2020.
Cash provided by investing activities primarily relates to proceeds of $119.8 million from our investments and proceeds of $6.0 million from the sale of our equity holdings. These cash receipts were partially offset by $16.9 million of purchased investments and $0.2 million of equipment purchases.
Net Cash Provided By Financing Activities
Net cash provided by financing activities was $53.3 million for the year ended December 31, 2021, as compared to $85.2 million for the year ended December 31, 2020.
Cash provided by financing activities during the year ended December 31, 2021 relates to $52.6 million of proceeds received from common shares sold pursuant to an at-the-market-issuance sales agreement, and $0.7 million of proceeds from employee shares purchased under our employee stock purchase plan.
Sale of Common Stock Under ATM Agreements
On April 5, 2019, we entered into a new collective at-market-issuance (“ATM”) sales agreement with Cantor Fitzgerald & Co., H.C. Wainwright & Co., LLC and B. Riley FBR, Inc. (the “April 2019 ATM Agreement”), pursuant to which we may offer and sell shares of our common stock by any method deemed to be an “at the market” offering (the “ATM Offering”). From April 5, 2019 to March 2, 2020, the ATM Offering was conducted pursuant to a sales agreement prospectus filed with our automatic shelf registration statement on Form S-3ASR, filed with the SEC on April 5, 2019, which registered an aggregate

Critical Accounting Policies and Estimates
The preparation and presentation of financial statements in conformity with generally accepted accounting principles in the United States of America, or GAAP requires our management to establish policies and make informed estimates and assumptions that affect (i) theour reported amounts of assets, liabilities, revenues, and liabilities as of the date presented on the accompanying Consolidated Balance Sheets and (ii) theexpenses. These amounts of revenue and expenses for each year presented in the accompanying Consolidated Statements of Operations.

Our management believes its estimates and assumptions are supportable, reasonable, and consistently applied. Nonetheless, estimates are inherently uncertain. As a result, our financial position and operating results couldmay materially differ from the amounts ultimately realized and reported within the accompanying Consolidated Financial Statements if management’s estimates require prospective adjustment. Our critical accounting policies and estimates arise in conjunction with the following accounts:
Revenue recognition
Inventories – lower of cost or net realizable value
Fair value of acquired assets and assumed liabilities
Goodwill and intangible assets – impairment evaluations
Income taxes
Stock-based compensation
Litigation accruals
Revenue Recognition
Impact of the Adoption of the New Revenue Recognition Standard:ASU No. 2014-09, Revenue from Contracts with Customers (“Topic 606”), became effective for us on January 1, 2018. Our disclosure within the below sections reflects our updated accounting policies that are affected by this new standard. We applied the “modified retrospective” transition method for open contracts for the implementation of Topic 606; thisresulted in the recognition of an aggregate $4.7 million, net of tax, decrease to our January 1, 2018 “accumulated deficit” on our accompanying Consolidated Balance Sheets for the cumulative impact of applying this new standard. We made no adjustments to our previously-reported total revenues, as those periods continue to be presented in accordance with our historical accounting practices under Topic 605, Revenue Recognition (“Topic 605”). See Notes 4, 5, and 20 to the accompanying Consolidated Financial Statements, for additional disclosures in accordance with Topic 606.
Required Elements of Our Revenue Recognition: Revenue from our (a) product sales, (b) out-license arrangements, and (c) service arrangements is recognized under Topic 606 in a manner that reasonably reflects the delivery of our goods and/or services to customers in return for expected consideration and includes the following elements:
(1)we ensure that we have an executed contract(s) with our customer that we believe is legally enforceable;
(2)we identify the “performance obligations” in the respective contract;
(3)we determine the “transaction price” for each performance obligation in the respective contract;
(4)we allocate the transaction price to each performance obligation; and
(5)we recognize revenue only when we satisfy each performance obligation.
    These five elements, as applied to each of our revenue categories, are summarized below:
(a) Product Sales: We sell our products to pharmaceutical wholesalers/distributors (i.e., our customers), except for our U.S. sales of ZEVALIN, and limited sales of EVOMELA, in which case the end-user (i.e., clinic or hospital) is our customer. Our wholesalers/distributors in turn sell our products directly to clinics, hospitals, and private oncology-based practices. Revenue from our product sales is recognized as physical delivery of product occurs (when our customer obtains control of the product), in return for agreed-upon consideration.
Our gross product sales (i.e., delivered units multiplied by the contractual price per unit) are reduced by our corresponding gross-to-net (“GTN”) estimates using the “expected value” method, resulting in our reported “product sales, net” in the accompanying Consolidated Statements of Operations, reflecting the amount we ultimately expect to realize in net cash proceeds, taking into account our current period gross sales and related cash receipts, and the subsequent cash disbursements on these sales that we estimate for the various GTN categories discussed below. These estimates are based upon information received from external sources (such as written or oral information obtained from our customers with respect to their period-

Table of Contents


end inventory levels and sales to end-users during the period), in combination with management’s informed judgments. Duedue to the inherent uncertainty of theseany estimate or assumption. On an on-going basis, our management evaluates (as applicable) its most critical estimates and assumptions, including those related to: (i) the actual amount incurred (of some, or all)realization of product returns, government chargebacks, prompt pay discounts, commercial rebates, Medicaid rebates,our tax assets and distribution, data, and GPO administrative fees may be materially above or below the amount estimated, then requiring prospective adjustments to our reported net product sales.
These GTN estimate categories are each discussed below:
Product Returns Allowances: Our FUSILEV, MARQIBO, and BELEODAQ customers are contractually permitted to return purchased products beginning at its expiration date and within six months thereafter. Our EVOMELA customers are permitted to return purchased product beginning at six months prior to its expiration date, and within 12 months thereafter (as well as for overstock inventory, as determined by end-users). ZEVALIN and FOLOTYN returns for expiry are not contractually permitted. Returns outside of this aforementioned criteria are not customarily allowed. We estimate expected product returns for our allowance based on our historical return rates. Returned product is typically destroyed, since substantially all returns are due to expiry and cannot be resold.
Government Chargebacks: Our products are subject to pricing limits under certain federal government programs (e.g., Medicare and 340B Drug Pricing Program). Qualifying entities (i.e., end-users) purchase products from our customers at their qualifying discounted price. The chargeback amount we incur represents the difference between our contractual sales price to our customer, and the end-user’s applicable discounted purchase price under the government program. There may be significant lag time between our reported net product sales and our receipt of the corresponding government chargeback claims from our customers.
Prompt Pay Discounts: Discounts for prompt payment are estimated at the time of sale, based on our eligible customers’ prompt payment history and the contractual discount percentage.
Commercial Rebates: Commercial rebates are based on (i) our estimates of end-user purchases through a group purchasing organization (“GPO”),our tax liabilities; (ii) the corresponding contractual rebate percentage tier we expect each GPO to achieve, and (iii) our estimates of the impact of any prospective rebate program changes made by us.
Medicaid Rebates: Our products are subject to state government-managed Medicaid programs, whereby rebates are issued to participating state governments. These rebates arise when a patient treated with our product is covered under Medicaid, resulting in a discounted price for our product under the applicable Medicaid program. Our Medicaid rebate accrual calculations require us to project the magnitude of our sales, by state, that will be subject to these rebates. There is a significant time lag in us receiving rebate notices from each state (generally several months or longer after our sale is recognized). Our estimates are based on our historical claim levels by state, as supplemented by management’s judgment.
Distribution, Data, and GPO Administrative Fees: Distribution, data, and GPO administrative fees are paid to authorized wholesalers/distributors of our products (except for U.S. sales of ZEVALIN) for various commercial services including: contract administration, inventory management, delivery of end-user sales data, and product returns processing. These fees are based on a contractually-determined percentage of our applicable sales.
(b) License Fees: Our out-license arrangements allow licensees to market our product(s) in certain territories for a specific term (representing the out-license of “functional intellectual property”). These arrangements may include one or more of the following forms of consideration: (i) upfront license fees, (ii) sales royalties, (iii) sales milestone-achievement fees, and (iv) regulatory milestone-achievement fees. We recognize revenue for each based on the contractual terms that establish our right to collect payment once the performance obligation is achieved, as follows:
(1) Upfront License Fees: We determine whether upfront license fees are earned at the time of contract execution (i.e., when rights transfer to the customer) or over the actual (or implied) contractual period of the out-license. As part of this determination, we evaluate whether we have any other requirements to provide substantive services that are inseparable from the performance obligation of the license transfer. Our customers’ “distinct” rights to licensed “functional intellectual property” at the time of contract execution results in concurrent revenue recognition of all upfront license fees (assuming that there are no other performance obligations at contract execution that are inseparable from this license transfer).

(2) Royalties: Under the “sales-or-usage-based royalty exception” we recognize revenue in the same period that our
licensees complete product sales in their territory for which we are contractually entitled to a percentage-based royalty receipt.

Table of Contents



(3) Sales Milestones: Under the “sales-or-usage-based royalty exception” we recognize revenue in full within the period that our licensees achieve annual or aggregate product sales levels in their territories for which we are contractually entitled to a specified lump-sum receipt.

(4) Regulatory Milestones: Under the terms of the respective out-license, regulatory achievements may either be our responsibility, or that of our licensee.

When our licensee is responsible for the achievement of the regulatory milestone, we recognize revenue in full (for the contractual amount due from our licensee) in the period that the approval occurs (i.e., when the “performance obligation” is satisfied by our customer) under the “most likely amount” method. This revenue recognition remains “constrained” (i.e., not recognized) until regulatory approval occurs, given its inherent uncertainty and the requirement of a significant revenue reversal not being probable if achievement does not occur. At each reporting period, we re-evaluate the probability of milestone achievement and the associated revenue constraint; any resulting adjustments would be recorded on a cumulative catch-up basis, thus reflected in our financial statements in the period of adjustment.

When we are responsible for the achievement of a regulatory milestone, the “relative selling price method” is applied for purposes of allocating the transaction price to our performance obligations. In such case, we consider (i) the extent of our effort to achieve the milestone and/or the enhancement of the value of the delivered item(s) as a result of milestone achievement and (ii) if the milestone payment is reasonable relative to all of the deliverables and payment terms (including other potential milestone consideration) within the arrangement. We have historically assessed the contractual value of these milestones upon their achievement to be identical to the allocation of value of our performance obligations and thus representing the “transaction price” for each milestone at contract inception. We recognize this revenue in the period that the regulatory approval occurs (i.e., when we complete the “performance obligation”) under the “most likely amount” method, and revenue recognition is otherwise “constrained” until regulatory approval occurs, given its inherent uncertainty and the requirement of a significant revenue reversal not being probable if achievement does not occur. At each reporting period, we re-evaluate the probability of milestone achievement and the associated revenue constraint; any resulting adjustments would be recorded on a cumulative catch-up basis, thus reflected in our financial statements in the period of adjustment.
(c) Service Revenue: We receive fees under certain arrangements for (i) sales and marketing services, (ii) supply chain services, (iii) research and development services, and (iv) clinical trial management services.
Our rights to receive payment for these services may be established by (1) a fixed-fee schedule that covers the term of the arrangement, so long as we meet ongoing performance obligations, (2) our completion of product delivery in our capacity as a procurement agent, (3) the successful completion of a phase of drug development, (4) favorable results from a clinical trial, and/or (5) regulatory approval events.
We consider whether revenue associated with these service arrangements is reportable each period, based on our completed services or deliverables (i.e., satisfied “performance obligations”) during the reporting period, and the terms of the arrangement that contractually result in fixed payments due to us. The promised service(s) within these arrangements are distinct and explicitly stated within each contract, and our customer benefits from the separable service(s) delivery/completion. Further, the nature of the promise to our customer as stated within the respective contract is to deliver each named service individually (not a transfer of combined items to which the promised goods or services are inputs), and thus are separable for revenue recognition.
Inventories – Lower of Cost or Net Realizable Value
We value our inventory at the lower of (i) the actual cost of its purchase or manufacture, or (ii) its net realizable value. Inventory cost is determined on the first-in, first-out method. We regularly review our inventory quantities in process of manufacture and on hand. When appropriate, we record a provision for obsolete and excess inventory to derive its new cost basis, which takes into account our sales forecast by product and corresponding expiry dates of each product lot.
Manufacturing costs of drug products that are pending FDA approval are fully expensed through “research and development,” on the accompanying Consolidated Statements of Operations.
Fair Value of Acquired Assets and Assumed Liabilities

55

Table of Contents


The accounting for business combinations and asset acquisitions requires extensive use of estimates and judgments to measure the fair value of the identifiable tangible and intangible assets acquired, including in-process research and development, and liabilities assumed. Additionally, we must determine whether the acquisition meets the criteria for business combination accounting (rather than asset acquisition accounting), because in a business combination, the excess of the purchase price over the fair value of net assets acquired can only be recognized as “goodwill.”
The fair value of acquired tangible and identifiable intangible assets and liabilities assumed, are based on their estimated fair values at the acquisition date and requires extensive use of accounting estimates, judgments, and assumptions, including but not limited to the following: (i) the likelihood, timing, and costs to complete the in-process projects; (ii) the probability of achieving regulatory approvals;our investments; (iii) the cash flows to be derived fromvaluation of our stock options and the acquired assets,periodic expense recognition of stock-based compensation; and (iv) the application of appropriate discount rates.
For each acquisition, we engage an independent third-party valuation specialist to assist management in determining the fair value of in-process research and development, identifiable intangible assets, and any contingent consideration.
In connection with certainpotential outcome of our acquisitions, we must record a contingent consideration liability for cashongoing or stock payments upon the completion of certain future performance milestones. In these cases, a liability is recorded on the acquisition date for an estimate of the acquisition date fair value of the contingent consideration by applying the income approach utilizing variable inputs such as probability of achievement and risk-free adjusted discount rates. Any change in the fair value of the contingent consideration subsequent to the acquisition date is recognized in earnings.

Goodwill and Intangible Assets – Impairment Evaluationsthreatened litigation.
Our goodwill representsaccounting policies and estimates that most significantly impact the excess of our business acquisitionpresented amounts within these Consolidated Financial Statements are further described below:
Property and Equipment, Net

Our property and equipment, net is stated at historical cost, over the estimated fair value of the net assets acquired in the corresponding transaction. Goodwill has an indefinite accounting life and is therefore not amortized. Instead, goodwill is evaluated for impairmentdepreciated on a straight-line basis over an annual basis (as of each October 1st), unless we identify impairment indicatorsestimated useful life that would require earlier testing.
corresponds with its designated asset category. We evaluate the recoverability of indefinite-lived intangible assets at least annually, or“long-lived assets” (which includes property and equipment) whenever events or changes in circumstances in our business indicate that an intangiblethe asset’s (whether indefinite or definite-lived) carrying amount may not be recoverable. Such circumstances could include, but are not limitedRecoverability is measured by a comparison of the carrying amount to the following:
(a) a significant decrease innet undiscounted cash flows expected to be generated by the marketasset group. An impairment loss would be recorded for the excess of net carrying value over the fair value of an asset;the asset impaired. The fair value is estimated based on expected discounted future cash flows or other methods such as orderly liquidation value based on assumptions of asset class and observed market data. An orderly liquidation value is the amount that could be realized upon liquidation, given a sufficient amount of time to find a purchaser for a sale of assets in their existing condition and location, as of a specific date, and assuming the sale is to market participants who can utilize such assets in their highest and best use. The orderly liquidation values are applied against the carrying values of the assets and the impairment loss is measured as the difference between the liquidation value and the carrying value of the assets.

During the fourth quarter of 2020, we determined that we would no longer proceed with the technology transfer and validation of a second manufacturing source for eflapegrastim and communicated this decision to the second source manufacturer. We had invested significant adverse change incapital to prepare this facility for production. Given the extent or manner in which an asset is used; or
(c) an accumulationdecision to discontinue this work, we determined that the value of costs significantlycertain eflapegrastim production equipment had a carrying amount in excess of the amount originally expected for the acquisition of an asset.
Intangible assets with finite useful lives are amortized over their estimated useful lives on a straight-line basis. We reviewanticipated recoverable value as there would be no future cash flows from these assets for potential impairment if/when facts or circumstances suggest thatother than through the carryingsale of this equipment. We determined the fair value of these assets may notunder an orderly liquidation value method and recorded an impairment of $19.7 million to our carrying value for this equipment, which was recorded as research and development expense. In connection with this decision, we additionally wrote off $8.5 million in prepaid costs related to future manufacturing activities that would no longer be recoverable.
Income Taxes
Deferred tax assetstaking place as research and liabilities aredevelopment expense. During the year ended December 31, 2021, this equipment was surrendered in connection with the termination of our agreement with our second source manufacturer and we recorded incremental research and development expense of $2.9 million. Fair value was based on the estimated future tax effects of temporary differences between the tax basis of assets and liabilities and amounts reported in the financial statements, as well as operating losses and tax credit carry forwards using enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. Realization of deferred tax assets is dependent upon future earnings, the timing and amount of which are uncertain.
We have recorded a valuation allowance to reduce our deferred tax assets, because we believe that, based upon a weighting of positive and negative factors, it is more likely than not that these deferred tax assets will not be realized. If/when we were to determine that our deferred tax assets are realizable, an adjustmentobservable market data (“Level 2”). Due to the corresponding valuation allowance would increase our net income in the period that such determination was made.
In the event that we are assessed interest and/or penalties from taxing authorities that have not been previously accrued, such amounts would be included in “(provision) benefit for income taxes” within the Consolidated Statementsspecialized nature of Operations in the period the notice was received.this production equipment, adjustments to observable market data were applied (“Level 3”).
Stock-Based Compensation
Stock-based compensation expense for equity awards granted to our employees and members of our Board of Directors is recognized on a straight-line basis over each award’s vesting period. Recognized compensation expense is net of an estimated forfeiture rate, representing the percentage of awards that are expected to be forfeited prior to vesting, though is ultimately

adjusted for actual forfeitures. We use the Black-Scholes option pricing model to determine the fair value of stock options and stock appreciation rights (as of the date of grant) that have service conditions for vesting. We use the Monte Carlo valuation model to value equity awards (as of the date of grant) that have combined market conditions and service conditions for vesting.
The recognition of stock-based compensation expense and the initial calculation of stock option fair value requires uncertain assumptions, including (a) the pre-vesting forfeiture rate of the award, (b) the expected term that the stock option will remain outstanding, (c) our stock price volatility over the expected term (and that of our designated peer group with respect to certain market-based awards), and (d) the prevailing risk-free interest rate for the period matching the expected term.
With regard to (a)-(d): We above: we estimate forfeiture rates based on our employees’ overall forfeiture history, which we believe will be representative of future results. We estimate the expected term of stock options granted based on our employees’ historical exercise patterns, which we believe will be representative of their future behavior. We estimate the volatility of our common stock on the date of grant based on the historical volatility of our common stock for a look-back period that corresponds with the expected term. We estimate the risk-free interest rate based upon the U.S. Department of the Treasury yields in effect at award grant, for a period equaling the expected term of the stock option.
Litigation Accruals
From time-to-time, we are involved with various legal matters arising from the ordinary course of operating our publicly-traded pharmaceutical business. These legal matters may include product liability claims, intellectual property claims, employment practices claims, shareholder claims, among other general claims. We accrue for these contingent liabilities when it is both: (1) probable that a payment will be made to the claimant, and (2) we can reasonably estimate the payment amount, given all available information.

** Effective December 2018, FUSILEV has been discontinued and we are no longer selling this product. We have since transitioned to marketing KHAPZORY for identical indications as FUSILEV.
Product sales, net. To derive net product sales, gross product revenues in each period are reduced by management's latest estimated provisions for (i) product returns, (ii) government chargebacks, (iii) prompt pay discounts, (iv) commercial rebates, (v) Medicaid rebates, and (vi) distribution, data, and GPO administrative fees. Management considers various factors in the determination of these provisions, which are described in more detail within “Critical Accounting Policies and Estimates” above.
FOLOTYN revenue increased $5.0 million due to an increase in our average net sales price per unit, partially offset by a decrease in units sold in the current year.
EVOMELA revenue decreased $6.9 million due to a decrease in our average net sales price per unit in the current year, partially offset by an increase in unit sales.
BELEODAQ revenue decreased $0.1 million due to a decrease in units sold, partially offset by an increase in our average net sales price per unit in the current year.
ZEVALIN revenue decreased $4.8 million due to a decrease in both units sold, and our average net sales price per unit.
MARQIBO revenue decreased $1.1 million due to a decrease in units sold during the period, partially offset by an increase in our average net sales price per unit.
FUSILEV revenue decreased $4.9 million as a result of both the decrease in the number of units sold and our average net sales price per unit, due to the competitive generic levo-leucovorin products, beginning in 2015 (see Note 3(f)) to our accompanying Consolidated Financial Statements). As noted above, effective December 2018, FUSILEV has been discontinued and we are no longer selling this product. We have since transitioned to marketing KHAPZORY for identical indications as FUSILEV.
KHAPZORY revenue of $0.9 million in the current year is due to its commercial launch during the fourth quarter of 2018.
License fees and service revenue. Our license fees and service revenue in 2018 decreased by $7.3 million primarily due to the following: (i) $4.7 million of non-recurring service revenue from our expired co-promotion arrangement with Eagle Pharmaceuticals, Inc. ("Eagle") in 2017 (see Note 14 to our accompanying Consolidated Financial Statements); and (ii) $4 million decrease in FOLOTYN royalties, primarily related to the non-recurrence of $5 million of regulatory and commercial milestone achievements of our licensee within Japan in 2017 (see Note 17(b)(vii) to our accompanying Consolidated Financial Statements). This decrease was partially offset by (i) $1 million milestone associated with our licensee's November 2018 Canadian approval of FOLOTYN (see Note 17(b)(xv)), and (ii) $0.8 million increase of ZEVALIN license fees within the Asia

Cost of Sales. Cost of sales decreased $16.1 million in 2018, primarily due to our product sales decrease, as well as the sales mix in each year.
Cost of Service Revenue. Cost of service revenue substantially relates to our allocated commercial and marketing expenses (from “selling, general, and administrative” expenses) for our 2017 promotion and sale of Eagle’s products by our sales force. We ceased marketing these products beginning July 1, 2017 (see Note 14 to the accompanying Consolidated Financial Statements).
Selling, General and Administrative. Selling, general and administrative expenses increased $6.4 million in 2018, primarily due to (i) the non-recurrence of certain marketing cost allocations out of this account; in the prior year, an aggregate $4.2 million was reclassified from this account and presented within “cost of service revenue” (see above for Eagle); (ii) $3.3 million increase in legal expenses primarily associated with the termination of our former chief executive officer in December 2017, and our corporate development initiatives; (iii) $2.2 million increase in various marketing activities, including the forthcoming commercial launch of ROLONTIS upon FDA approval; (iv) $2.1 million increase in payroll tax expenses primarily related to stock option exercises during the year by our former chief executive officer; and (v) $1.7 million increase in various other expenses to further support our current operations and planned business growth. These increases were partially offset by a $7 million decrease in personnel and benefit-related costs as compared to prior year, largely attributable to the contractual amounts due to our former chief executive officer upon his termination in December 2017.
Research and Development.Development Costs
Our research and development costs are expensed as incurred. Research and development expenses increased $29.1 million in 2018 due to several factors, including: (i) $19.1 million increase in productcosts consist primarily of salaries, benefits, and other staff-related costs including associated stock-based compensation, laboratory supplies, clinical trial and related clinical manufacturing costs, costs related to the planned commercial launch of ROLONTIS; (ii) $0.9 million increase in clinical activities; (iii) $2.9 million increase in pre-FDA approval manufacturing costs associated with the launch of KHAPZORY in the fourth quarter of 2018; (iv) $0.9 million increase in product development costs for BELEODAQ; (v) $0.8 million in technical transfer costs associated with ZEVALIN production at a new site; (vi) $0.8 million increase in manufacture validation costs for EVOMELA production at a new site; and (vii) $5.2 million increase in personnel-related costs to drive these various clinical, manufacture validation, and product development initiatives. These increases were partially offset by a $2.7 million decrease in product manufacturing costs associated with QAPZOLA, as we refine our product development priorities.
Amortization and Impairment Charges of Intangible Assets. Amortization expense, recorded on a straight-line basis, increased in 2018 due to the capitalization of KHAPZORY distribution rights and its incremental amortization in the current year (see Note 3(g)).

Total other income (expense) increased by $22.6 million due to multiple offsetting components including: (i) $10.5 million increase in unrealized gain on our CASI Pharmaceuticals, Inc. equity securities, which are now recorded within “other income (expense), net” rather than “other comprehensive (loss) income” due to our adoption of ASU 2016-01 (see Note 3(a) to our accompanying Consolidated Financial Statements); (ii) $7.3 million aggregate decrease of interest and principal retirement expense related to our 2018 Convertible Notes (see Note 15 to our accompanying Consolidated Financial Statements); and (iii) $6.9 million decrease in the fair value of contingent consideration related to our MARQIBO product (see Note 10(a) to our accompanying Consolidated Financial Statements). These net increasespreparations, fees paid to other income was partially offset by $2 million increase in executive deferred compensation expense (see Note 17(f) to our accompanying Consolidated Financial Statements).

Our provision for income taxes was a nominal $1 thousand for 2018. Our $16.8 million benefit for income taxes in 2017 principally relates to tax benefits allocated to continuing operations as a result of unrealized gains in "other comprehensive income (loss)". During 2017, we had unrealized gains from the change in value of our available-for-sale securitiesentities that are reported within "other comprehensive income (loss)" of $25.8 million, while we also reported a pretax "loss from continuing operations" of $108 million. These gains in "other comprehensive income (loss)" resulted in our recording a tax benefit of $9.7 million to continuing operations and an offsetting tax charge to "other comprehensive income (loss)" of $9.7 million (this did not recur in the current year with our January 1, 2018 adoption of ASU 2016-01, Recognition and Measurement of Financial Assets and Liabilities). The other portion of our 2017 benefit for income taxes relates to the re-measurement of deferred taxes and our updated assessment of the realizability of deferred tax assets, as part of the enactment of the Tax Jobs and Cuts Act.

rebates, (v) Medicaid rebates, and (vi) distribution, data, and GPO administrative fees. Management considers various factors in the determination of these provisions, which are described in more detail within “Critical Accounting Policies and Estimates” above.
FOLOTYN revenue decreased $3.2 million in 2017 compared to 2016 as a result of a decrease in the numbers of units sold in the year, partially offset by an increase in our net average sales price per unit.
EVOMELA revenue increased significantly by $19.0 million during 2017 compared to 2016 as a result of an increase in the number of units sold, partially offset by a decrease in our average net sales price per unit. The commercial launch of this product commenced in April 2016.
BELEODAQ revenue decreased $1.0 million in 2017 compared to 2016 primarily as a result of a decrease in the number of units sold in the current year, and also as a result of a decrease in our average net sales price per unit.
ZEVALIN revenue increased $1.1 million in 2017 compared to 2016 primarily as a result of an overall increase in units sold and an increase in the net average price per unit in our ex-U.S territories.
MARQIBO revenue decreased $0.6 million in 2017 compared to 2016 as a result of a decline in the number of units sold in the year, partially offset by an increase in our net average sales price per unit.

FUSILEV revenue decreased $27.5 million in 2017 compared to 2016 as a result of the continued significant decline in both our net average sales price and unit sales due to the competitive launch of generic levo-leucovorin products beginning in April 2015 (see Note 3(g) to the accompanying Consolidated Financial Statements).
License fees and service revenue. Our license fees and service revenue in 2017 decreased by $5.6 million primarily due to the following: (i) an upfront receipt of $6 million in 2016 for the out-license of ZEVALIN, FOLOTYN, BELEODAQ, and MARQIBO (see Note 13 to the accompanying Consolidated Financial Statements) which did not reoccur in 2017, (ii) $4.3 million decrease in fees from our co-promotion with Eagle (see Note 14 to the accompanying Consolidated Financial Statements) as our sales force is no longer marketing Eagle's products as of July 1, 2017, and (iii) $0.5 million decrease in our sales of ZEVALIN to Asia andconduct certain other territories, excluding China (see Note 12 to the accompanying Consolidated Financial Statements). These decreases were partially offset by the recognition in 2017 of (i) $3.0 million contractual milestone for FOLOTYN approval in Japan, (ii) $2.0 million contractual milestone receipt for the first commercial sale of FOLOTYN in Japan (see Note 17(b)(vii) to the accompanying Consolidated Financial Statements), and (iii) $0.3 million of regulatory service revenue that was provided for the benefit of our licensee.

Cost of Sales. Despite our decreased product revenue in 2017, cost of sales increased $14.9 million in 2017 compared to 2016, resulting in a gross margin decrease. This increase in cost of sales was primarily due to (i) changes to our product sales mix and (ii) royalty expense for FOLOTYN regulatory and commercial milestone achievements (see Note 17(b)(vii) to the accompanying Consolidated Financial Statements), partially offset by our FUSILEV royalty settlement also recognized in 2017 (see Note 17(b)(v) to the accompanying Consolidated Financial Statements).

Cost of Service Revenue. Cost of service revenue substantially relates to our allocated commercial and marketing expenses (from "selling, general, and administrative" expenses) for promotion and sale of Eagle's products by our sales force. Our cost of service revenue decreased $3.5 million in 2017 compared to 2016 because we ceased marketing these products beginning July 1, 2017 (see Note 14 to the accompanying Consolidated Financial Statements).
Selling, General and Administrative. Selling, general and administrative expenses decreased $4.1 million largely driven by a $12.3 million decrease in non-recurring legal expenses and settlements related to shareholder litigation and FOLOTYN patent matters in 2016, and $2.4 million of non-recurring contract termination fees in 2016. These overall reductions were partially offset by (i) one-time severance and legal expenses of $7.1 million associated with the termination of our former chief executive officer in December 2017, and (ii) $3.7 million increase related to reimbursable expenses from Eagle as the agreement expired under its terms on June 30, 2017 (see Note 14).
Research and Development. Research and development expenses increased in 2017 by $6.8 million compared to the prior year due to various items primarily including (i) $7.1 million increase in clinical initiatives and activities primarily related to ROLONTIS and POZIOTINIB, and (ii) $1.2 million FDA filing fee associated with the NDA for KHAPZORY, and a corresponding $0.3 million milestone payment to a licensor. These increases were partially offset by decreased expense associated with ROLONTIS, attributable to a non-recurring $2.7 million clinical milestone fee in 2016 (see Note 17(b)(xiii) to the accompanying Consolidated Financial Statements).
Amortization and Impairment Charges of Intangible Assets. Amortization expense increased $1.7 million in 2017 compared to 2016 due to a prospectively-applied adjustment in June 2016 of the amortization period of our FOLOTYN distribution rights (to November 2022 from March 2025), representing the period through which we expect to have patent protection from generic competition (see Note 3(g) to the accompanying Consolidated Financial Statements). As a result, in 2017 we incurred a full-year of increased amortization expense related to this adjustment. Amortization expense otherwise remained consistent with the prior year period as we continue to recognize expense on a straight-line basis for the distribution rights to our commercialized products.

Total other expenses$(11.4) $(9.2) $(2.2) (23.9)%
Total other expenses increased $2.2 million in 2017 compared to 2016 due to multiple offsetting components, including (i) $0.8 million loss on our 2018 Convertible Notes repurchase of $69.5 million (see Note 15 to the accompanying Consolidated Financial Statements), (ii) $0.6 million increase in foreign currency exchange rate translation adjustment (i.e. unrealized loss), and (iii) $5.0 million increase in the fair value of contingent consideration related to our MARQIBO product (see Note 10(a) to the accompanying Consolidated Financial Statements), offset by a $0.8 million decrease in the fair value of contingent consideration related to our EVOMELA product (see Note 10(b) to the accompanying Consolidated Financial Statements) that is recognized through "other (expense) income" for its quarterly re-measurement. In 2017, we increased our revenue projections for in development indications of MARQIBO, and this led to an overall increase in the contingent consideration liability and corresponding expense. These expense increases were partially offset by (i) $2.6 million decrease in interest expense on our 2018 Convertible Notes as a result of our December 2016 and October 2017 repurchases of $10 million and $69.5 million principal of these notes, respectively (see Note 15 to the accompanying Consolidated Financial Statements), and (ii) a $0.9 million decrease in executive deferred compensation expense as a result of increases in the fair value of plan assets (see Note 17(f)) to the accompanying Consolidated Financial Statements).

Our $16.8 million benefit for income taxes in 2017 principally relates to tax benefits allocated to continuing operations as a result of unrealized gains in "other comprehensive income (loss)". During 2017, we had unrealized gains from the change in value of our available-for-sale securities that are reported within "other comprehensive income (loss)" of $25.8 million, while we also reported a pretax "loss from continuing operations" of $108 million. The gains in "other comprehensive income (loss)" resulted in our recording a tax benefit of $9.7 million to continuing operations and an offsetting tax charge to "other comprehensive income (loss)" of $9.7 million. The remaining benefit for 2017 income taxes relates to the re-measurement of deferred taxes and changes in judgment regarding the realizability of deferred tax assets, resulting from tax changes enacted as part of the Tax Jobs and Cuts Act.
Our 2016 benefit for income taxes of $2.3 million is primarily due to unrealized gains from the change in value of our available-for-sale securities while we also reported a pretax operating loss in the same period.

Net Cash Used In Operating Activities
Cash used in operating activities was $62.4 million in 2018, as compared to $38.9 million and $40.5 million in 2017 and 2016, respectively.
For the years ended December 31, 2018, 2017, and 2016, our cash collections from customers totaled $126.3 million, $161.5 million, and $159.5 million respectively, representing 115%, 126%, and 109% of reported net revenue for the same years.
For the years ended December 31, 2018, 2017, and 2016, cash payments to our employees and vendors for products, services, and rebates totaled $209.7 million, $210.2 million, and $206.9 million respectively.
Net Cash Provided By (Used In) Investing Activities
Net cash provided by investing activities was $1.4 million for the year ended December 31, 2018, as compared to $1.1 million and $0.7 million of cash used in investing activities for the years ended December 31, 2017 and 2016, respectively. Our cash provided by investing activities in 2018 primarily related to $4.1 million receipt of cash for corporate-owned life insurance premiums. This amount was partially offset by (i) cash paid for KHAPZORY distribution rights of $2.7 million (see Note 3(g)), and (ii) $0.1 million of computer hardware and software purchases.
Net Cash (Used In) Provided By Financing Activities
Net cash used in financing activities was $8.5 million for the year ended December 31, 2018, as compared to $108.7 million and $59.6 million of cash provided by financing activities for the years ended December 31, 2017 and 2016, respectively. Our cash used in financing activities during the year ended December 31, 2018 related to: (i) $13.5 million of proceeds from the issuance of common stock as a result of the exercise of employee stock options, (ii) $1.1 million of proceeds from employee stock purchases under our employee stock purchase plan, and (iii) $4.6 million of proceeds received from employees related to remittances to federal and state tax authorities for taxes due at vesting/exercise of equity awards. These amounts were offset by (i) $27.7 million of aggregate payments to federal and state tax authorities related to our employees’ tax

liabilities at the time of stock vestings and exercises, and (ii) $20 thousand payment upon the maturity of our 2018 Convertible Notes on December 15, 2018 (see Note 15).

2013 Convertible Senior Notes - Maturity on December 15, 2018
On December 17, 2013, we entered into an agreement for the sale of $120 million aggregate principal amount of 2.75% Convertible Senior Notes (equaling 120,000 notes, denominated in $1,000 principal units) the "2013 Convertible Notes." As of December 31, 2017, $38.2 million of debt principal was outstanding. Maturity of the 2013 Convertible Notes occurred on December 15, 2018, and substantially all of these notes were converted into our common stock at a rate of 95 shares per $1,000 principal units, with an in-the-money conversion price of $10.53 per common share. As a result, there were no amounts outstanding as of December 31, 2018.

Sale of Common Stock Under ATM Agreements
In December 2015 and August 2017, we entered into collective at-market-issuance sales agreements with FBR Capital Markets & Co., MLV & Co. LLC, and H.C. Wainwright & Co., LLC. These agreements allowed us to raise aggregate gross proceeds through these brokers of up to $250 million from the sale of our common stock on the public market.
Through December 31, 2018, we had raised aggregate gross net proceeds of $202.1 million through these at-market sales, of which $128.3 million was raised during the year ended December 31, 2017. We had no sales under the ATM during the year ended December 31, 2018. We are using these proceeds to continue to develop our product pipeline and to provide additional capital structure flexibility.

Sale of Our Commercialized Drug Portfolio and Future Proceeds

On January 17, 2019, we entered into a definitive asset purchase agreement for the sale of our FDA-approved product portfolio of FUSILEV, KHAPZORY, FOLOTYN, ZEVALIN, MARQIBO, BELEODAQ, and EVOMELA to Acrotech. Upon the closing of the Acrotech Transaction, we are entitled to receive up to $160 million in an upfront cash payment (of which $4 million will be held in escrow for six months). In addition, we expect a purchase price adjustment for certain ongoing research and development activities of the commercialized product portfolio. We are also entitled to receive an aggregate $140 million upon Acrotech's achievement of certain regulatory and sales-based milestones relating to this product portfolio. We plan to reduce our staff by approximately 90 employees, the majority of which we expect to transition to Acrotech.

We plan to use the anticipated proceeds from the Acrotech Transaction to advance our in-development drug pipeline, as well as providing for our general working capital requirements.
Future Capital Requirements
We believe that the future growth of our business will depend on our abilitybehalf and payments made pursuant to successfully developlicense agreements. Clinical trial and acquire new drugsother development costs incurred by third parties are expensed as the contracted work is performed. We accrue for costs incurred as the treatmentservices are being provided by monitoring the status of cancer and successfully bring these drugs to market.
The timing and amount of our future capital requirements will depend on many factors, including:
the need for additional capital to fund future development programs;
the need for additional capital to fund strategic acquisitions;
the need for additional capital to fund licensing arrangements;
our requirement for additional information technology infrastructure and systems; and
adverse outcomes from potential litigationactivities and the costinvoices received from its external service providers. We adjust our accruals as actual costs become known. Where contingent milestone payments are due to defend such litigation.third parties under research and development or license agreements, the milestone payment obligations are expensed when the clinical or regulatory milestone results are achieved.
We believe that our $204 million in aggregate cash and cash equivalents, and marketable securities as of December 31, 2018, in addition to the pending proceeds from the Acrotech Transaction, will be sufficient to fund operations for at least the next three years.
We may, however, require additional liquidity as we continue to execute our business strategy, and in connection with opportunistic acquisitions or licensing arrangements. We anticipate that to the extent that we require additional liquidity, it will be funded through additional equity or debt financings (see Note 7 to the accompanying Consolidated Financial Statements). We cannot assure you that we will be able to obtain this additional liquidity on terms favorable to us or our current stockholders, or at all. Additionally, our liquidity and our ability to fund our capital requirements are also dependent on our

(2)Purchase obligations represent the amount of open purchase orders and contractual commitments to vendors for products and services that have not been delivered, or rendered, as of December 31, 2018.
(3)Milestone obligations are payable contingent upon successfully reaching certain development and regulatory milestones. Given the unpredictability of the drug development process, and the impossibility of predicting the success of current and future clinical trials, these values assume that all development and regulatory milestones under all of our license agreements are successfully met, and represent our best estimate of each achievement date. In the event that the milestones are met, we believe it is likely that the increase in the potential value of the related drug product will exceed the amount of the milestone obligation.

Research and development services under the Mundipharma Collaboration Agreement (see Note 16 to the accompanying Consolidated Financial Statements) over the period required to complete the jointly agreed-upon clinical development activities.
Off-Balance Sheet Arrangements
We have no off-balance sheet arrangements (except for operating leases) that provide financing, liquidity, market or credit risk support, or involve derivatives. In addition, we have no arrangements that may expose us to liability that are not expressly reflected in the accompanying Consolidated Financial Statements and/or notes thereto.
As of December 31, 2018, we did not have any relationships with unconsolidated entities or financial partnerships, often referred to as “structured finance” or “special purpose entities,” established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As such, we are not subject to any material financing, liquidity, market or credit risk that could arise if we had engaged in such relationships.

ITEMItem 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKQuantitative And Qualitative Disclosures About Market Risk
In the normal course of business, our operations are exposed to risks associated with fluctuations in interest rates and foreign currency exchange rates.
The primary objective of our investment activities is to preserve principal, while at the same time maximizing yields without significantly increasing risk. We do not utilize hedging contracts or similar instruments as part of our investing activities. Because of our ability to generally redeem these investments at par on short notice and without penalty, changes in interest rates would have an immaterial effect on the fair value of these investments. If a 10% change in interest rates were to have occurred on December 31, 2018, any decline in the fair value of our investments would not be material in the context of our accompanying Consolidated Financial Statements. In addition, we are exposed to certain market risks associated with credit ratings of corporations whose corporate bonds we may purchase from time to time. If these companies were to experience a significant detrimental change in their credit ratings, the fair market value of such corporate bonds may significantly decrease.

Not applicable.

Table of Contents



If these companies were to default on these corporate bonds, we may lose part or all of our principal. We believe that we effectively manage this market risk by diversifying our investments, and investing in highly rated securities.
We are exposed to foreign currency exchange rate fluctuations relating to payments we make to vendors, suppliers and license partners in Euros (and other currencies to a lesser extent). We mitigate this risk by maintaining a limited portion of our cash in Euros for our vendor payments in Euros.

The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

NOTE 1. DESCRIPTION OF BUSINESS, BASIS OF PRESENTATION, AND OPERATING SEGMENT
(a) Description of Business
Spectrum Pharmaceuticals, Inc. (“Spectrum,”Spectrum”, the “Company,” “we,” “our,”“Company”, “we”, “our”, or “us”) is a biopharmabiopharmaceutical company, with a primary strategy comprised of acquiring, developing, and commercializing a broadnovel and diverse pipeline oftargeted oncology therapies. Our in-house development organization includes clinical development, regulatory, quality and commercial products. data management.
We have an in-house clinical development organization with regulatory and data management capabilities, in addition to commercial infrastructure and a field-based sales force for our marketed products. Currently, we have seven approved oncology/hematology products (FUSILEV, KHAPZORY, FOLOTYN, ZEVALIN, MARQIBO, BELEODAQ, and EVOMELA) that target different types of non-Hodgkin's lymphoma ("NHL"), advanced metastatic colorectal cancer ("mCRC"), acute lymphoblastic leukemia ("ALL"), and multiple myeloma ("MM").
We also have two2 drugs in late-stage development:
Eflapegrastim, a novel long-acting granulocyte colony-stimulating factor (“G-CSF”) for the treatment of chemotherapy-induced neutropenia. On August 6, 2021, the Company announced the receipt of a complete response letter (“CRL”), that cited manufacturing deficiencies related both to the drug substance and drug product manufacturers.The Company believes it has completed the remediation of these deficiencies and resubmitted the Biologics License Application (“BLA”) on March 11, 2022;
Poziotinib, a novel pan-HERirreversible tyrosine kinase inhibitor under investigation for non-small cell lung cancer ("NSCLC"(“NSCLC”) tumors with either EGFRvarious mutations. On December 6, 2021, the Company announced it submitted its New Drug Application (“NDA”) for poziotinib to the FDA for use in patients with previously treated locally advanced or metastatic NSCLC with HER2 exon-20exon 20 insertion mutations;mutations. The NDA submission is based on the positive results of Cohort 2 from the ZENITH20 clinical trial, which assessed the safety and
ROLONTIS, efficacy of poziotinib. The product has received Fast Track designation and there is currently no treatment specifically approved by the FDA for this indication. On February 11, 2022, the Company announced that it had received notice that the NDA had been accepted and received a novel long-acting granulocyte colony-stimulating factor ("G-CSF"), analog for chemotherapy-induced neutropenia.
On January 17, 2019, we entered into a definitive asset purchase agreement for the salePDUFA action date of our FDA-approved product portfolio of FUSILEV, KHAPZORY, FOLOTYN, ZEVALIN, MARQIBO, BELEODAQ, and EVOMELA to Acrotech Biopharma L.L.C. ("Acrotech"), a New Jersey-based wholly-owned subsidiary of Aurobindo Pharma USA Inc. (the "Acrotech Transaction"). Upon the closing of the Acrotech Transaction, we are entitled to receive up to $160 million in an upfront cash payment (of which $4 million will be held in escrow for six months). In addition, we expect a purchase price adjustment for certain ongoing research and development activities of the commercialized product portfolio. We are also entitled to receive an aggregate $140 million upon Acrotech's achievement of certain regulatory and sales-based milestones relating to this product portfolio. We plan to reduce our staff by approximately 90 employees, the majority of which we expect to transition to Acrotech. The accounting recognition and financial reporting for the disposal of this commercial component of our business will be reflected in our financial statements in the period corresponding with its closing.November 24, 2022.
(b) Basis of Presentation
Principles of Consolidation
The accompanying Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP"(“GAAP”) and with the rules and regulations of the Securities and Exchange Commission ("SEC"(“SEC”). These financial statements include the financial position, results of operations, and cash flows of Spectrum and its subsidiaries, all of which are wholly-owned (except for Spectrum Pharma Canada ("SPC")), as discussed below.wholly-owned. All inter-company accounts and transactions among these legal entities have been eliminated in consolidation. Substantially all of the accumulated other comprehensive loss is comprised of foreign currency translation adjustments at December 31, 2021.
Variable Interest Entity
We own fifty-percent of SPC, a legal entity organized in Quebec, Canada in January 2008. SomeDiscontinued Operations - Sale of our clinical studiesCommercial Product Portfolio
In March 2019, we completed the Commercial Product Portfolio Transaction (See Note 9 ). In accordance with applicable GAAP (ASC 205-20, Presentation of Financial Statements), the revenue-deriving activities and allocable expenses of our sold commercial operation, connected to the Commercial Product Portfolio, are conducted through this “variable interest entity” (as defined under applicable GAAP). We fund all of SPC’s operating costs, and since we assume all risks and rewards for this entity, we meet the criteriaseparately classified as being its “primary beneficiary” (as defined under applicable GAAP). Accordingly, SPC’s balance sheets and statements of operations are included in our Consolidated Financial Statements as if it were a wholly-owned subsidiary“discontinued” for all periods presented.presented within the accompanying Consolidated Statements of Operations.
Liquidity and Capital Resources
We believe that our $100.6 million in aggregate cash, cash equivalents, and marketable securities as of December 31, 2021 combined with $20 million of equity financing received from Hanmi in January 2022 is sufficient to fund our current and planned operations for at least the next twelve months. We may, however, require additional liquidity as we continue to execute our business strategy, and in connection with opportunistic acquisitions or licensing arrangements. We anticipate that to the extent that we require additional liquidity, it will be funded through additional equity or debt financings, or out-licensing arrangements. However, we cannot provide assurance that we will be able to obtain this additional liquidity on terms favorable to us or our current stockholders, if at all. Additionally, our liquidity and our ability to fund our capital requirements are also dependent on our future financial performance which is subject to various market and economic factors that are beyond our control.
(c) Operating Segment
We operate in one1 reportable operating segment that is focused exclusively on developing and marketing(and eventually marketing) oncology and hematology drug products. For the years ended December 31, 2018, 2017,2021 and 2016,2020, all of our revenueoperating costs and related expenses were solely attributable to these activities. Substantially all of our assets (excluding our cash held in certain foreign bank accounts and our ZEVALIN distribution rights for the ex-U.S. territories - see Note 3(g)) are held in the U.S.

expenses were solely attributable to these activities (and as applicable, classified as “discontinued” within the accompanying Consolidated Statements of Operations).


NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND USE OF ESTIMATES
The preparation of financial statements in conformity with GAAP requires our management to make informed estimates and assumptions that affect our reported amounts of assets, liabilities, revenues, and expenses. These amounts may materially differ from the amounts ultimately realized and reported due to the inherent uncertainty of any estimate or assumption. On an on-going basis, our management evaluates (as applicable) its most critical estimates and assumptions, including those related to: (i) gross-to-net revenue adjustments; (ii) the timing of revenue recognition; (iii) the collectability of customer accounts; (iv) whether the cost of our inventories can be recovered; (v) the recoverability of our reported goodwill and intangible assets; (vi) the realization of our tax assets and estimates of our tax liabilities; (vii) the likelihood of payment and value of contingent liabilities; (viii)(ii) the fair value of our investments; (ix)(iii) the valuation of our stock options and the periodic expense recognition of stock-based compensation; and (x)(iv) the potential outcome of our ongoing or threatened litigation.
Our accounting policies and estimates that most significantly impact the presented amounts within these Consolidated Financial Statements are further described below:
(i) Revenue Recognition
Impact of the Adoption of the New Revenue Recognition Standard:ASU No. 2014-09, Revenue from Contracts with Customers (“Topic 606”), became effective for us on January 1, 2018. Our disclosure within the below sections to this footnote reflects our updated accounting policies that are affected by this new standard. We applied the “modified retrospective” transition method for open contracts for the implementation of Topic 606; thisresulted in the recognition of an aggregate $4.7 million, net of tax, decrease to our January 1, 2018 “accumulated deficit” on our accompanying Consolidated Balance Sheets for the cumulative impact of applying this new standard. We made no adjustments to our previously-reported total revenues, as those periods continue to be presented in accordance with our historical accounting practices under Topic 605, Revenue Recognition (“Topic 605”). See Notes 4, 5, and 20 for additional quantitative and qualitative revenue disclosures in accordance with Topic 606.
Required Elements of Our Revenue Recognition: Revenue from our (a) product sales, (b) out-license arrangements, and (c) service arrangements is recognized under Topic 606 in a manner that reasonably reflects the delivery of our goods and/or services to customers in return for expected consideration and includes the following elements:
(1)we ensure that we have an executed contract(s) with our customer that we believe is legally enforceable;
(2)we identify the “performance obligations” in the respective contract;
(3)we determine the “transaction price” for each performance obligation in the respective contract;
(4)we allocate the transaction price to each performance obligation; and
(5)we recognize revenue only when we satisfy each performance obligation.
    These five elements, as applied to each of our revenue categories, are summarized below:
(a) Product Sales: We sell our products to pharmaceutical wholesalers/distributors (i.e., our customers), except for our U.S. sales of ZEVALIN, and limited sales of EVOMELA, in which case the end-user (i.e., clinic or hospital) is our customer. Our wholesalers/distributors in turn sell our products directly to clinics, hospitals, and private oncology-based practices. Revenue from our product sales is recognized as physical delivery of product occurs (when our customer obtains control of the product), in return for agreed-upon consideration.
Our gross product sales (i.e., delivered units multiplied by the contractual price per unit) are reduced by our corresponding gross-to-net (“GTN”) estimates using the “expected value” method, resulting in our reported “product sales, net” in the accompanying Consolidated Statements of Operations, reflecting the amount we ultimately expect to realize in net cash proceeds, taking into account our current period gross sales and related cash receipts, and the subsequent cash disbursements on these sales that we estimate for the various GTN categories discussed below. These estimates are based upon information received from external sources (such as written or oral information obtained from our customers with respect to their period-end inventory levels and sales to end-users during the period), in combination with management’s informed judgments. Due to the inherent uncertainty of these estimates, the actual amount incurred (of some, or all) of product returns, government chargebacks, prompt pay discounts, commercial rebates, Medicaid rebates, and distribution, data, and GPO administrative fees may be materially above or below the amount estimated, then requiring prospective adjustments to our reported net product sales.
These GTN estimate categories are each discussed below:

F-9

Notes to Consolidated Financial Statements
(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)




Product Returns Allowances: Our FUSILEV, MARQIBO, and BELEODAQ customers are contractually permitted to return purchased products beginning at its expiration date and within six months thereafter. Our EVOMELA customers are permitted to return purchased product beginning at six months prior to its expiration date, and within 12 months thereafter (as well as for overstock inventory, as determined by end-users). ZEVALIN and FOLOTYN returns for expiry are not contractually permitted. Returns outside of this aforementioned criteria are not customarily allowed. We estimate expected product returns for our allowance based on our historical return rates. Returned product is typically destroyed, since substantially all returns are due to expiry and cannot be resold.
Government Chargebacks: Our products are subject to pricing limits under certain federal government programs (e.g., Medicare and 340B Drug Pricing Program). Qualifying entities (i.e., end-users) purchase products from our customers at their qualifying discounted price. The chargeback amount we incur represents the difference between our contractual sales price to our customer, and the end-user’s applicable discounted purchase price under the government program. There may be significant lag time between our reported net product sales and our receipt of the corresponding government chargeback claims from our customers.
Prompt Pay Discounts: Discounts for prompt payment are estimated at the time of sale, based on our eligible customers’ prompt payment history and the contractual discount percentage.
Commercial Rebates: Commercial rebates are based on (i) our estimates of end-user purchases through a group purchasing organization (“GPO”), (ii) the corresponding contractual rebate percentage tier we expect each GPO to achieve, and (iii) our estimates of the impact of any prospective rebate program changes made by us.
Medicaid Rebates: Our products are subject to state government-managed Medicaid programs, whereby rebates are issued to participating state governments. These rebates arise when a patient treated with our product is covered under Medicaid, resulting in a discounted price for our product under the applicable Medicaid program. Our Medicaid rebate accrual calculations require us to project the magnitude of our sales, by state, that will be subject to these rebates. There is a significant time lag in us receiving rebate notices from each state (generally several months or longer after our sale is recognized). Our estimates are based on our historical claim levels by state, as supplemented by management’s judgment.
Distribution, Data, and GPO Administrative Fees: Distribution, data, and GPO administrative fees are paid to authorized wholesalers/distributors of our products (except for U.S. sales of ZEVALIN) for various commercial services including: contract administration, inventory management, delivery of end-user sales data, and product returns processing. These fees are based on a contractually-determined percentage of our applicable sales.
(b) License Fees: Our out-license arrangements allow licensees to market our product(s) in certain territories for a specific term (representing the out-license of “functional intellectual property”). These arrangements may include one or more of the following forms of consideration: (i) upfront license fees, (ii) sales royalties, (iii) sales milestone-achievement fees, and (iv) regulatory milestone-achievement fees. We recognize revenue for each based on the contractual terms that establish our right to collect payment once the performance obligation is achieved, as follows:
(1) Upfront License Fees: We determine whether upfront license fees are earned at the time of contract execution (i.e., when rights transfer to the customer) or over the actual (or implied) contractual period of the out-license. As part of this determination, we evaluate whether we have any other requirements to provide substantive services that are inseparable from the performance obligation of the license transfer. Our customers’ “distinct” rights to licensed “functional intellectual property” at the time of contract execution results in concurrent revenue recognition of all upfront license fees (assuming that there are no other performance obligations at contract execution that are inseparable from this license transfer).

(2) Royalties: Under the “sales-or-usage-based royalty exception” we recognize revenue in the same period that our
licensees complete product sales in their territory for which we are contractually entitled to a percentage-based royalty receipt.

(3) Sales Milestones: Under the “sales-or-usage-based royalty exception” we recognize revenue in full within the period that our licensees achieve annual or aggregate product sales levels in their territories for which we are contractually entitled to a specified lump-sum receipt.

(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)




(4) Regulatory Milestones: Under the terms of the respective out-license, regulatory achievements may either be our responsibility, or that of our licensee.

When our licensee is responsible for the achievement of the regulatory milestone, we recognize revenue in full (for the contractual amount due from our licensee) in the period that the approval occurs (i.e., when the “performance obligation” is satisfied by our customer) under the “most likely amount” method. This revenue recognition remains “constrained” (i.e., not recognized) until regulatory approval occurs, given its inherent uncertainty and the requirement of a significant revenue reversal not being probable if achievement does not occur. At each reporting period, we re-evaluate the probability of milestone achievement and the associated revenue constraint; any resulting adjustments would be recorded on a cumulative catch-up basis, thus reflected in our financial statements in the period of adjustment.

When we are responsible for the achievement of a regulatory milestone, the “relative selling price method” is applied for purposes of allocating the transaction price to our performance obligations. In such case, we consider (i) the extent of our effort to achieve the milestone and/or the enhancement of the value of the delivered item(s) as a result of milestone achievement and (ii) if the milestone payment is reasonable relative to all of the deliverables and payment terms (including other potential milestone consideration) within the arrangement. We have historically assessed the contractual value of these milestones upon their achievement to be identical to the allocation of value of our performance obligations and thus representing the “transaction price” for each milestone at contract inception. We recognize this revenue in the period that the regulatory approval occurs (i.e., when we complete the “performance obligation”) under the “most likely amount” method, and revenue recognition is otherwise “constrained” until regulatory approval occurs, given its inherent uncertainty and the requirement of a significant revenue reversal not being probable if achievement does not occur. At each reporting period, we re-evaluate the probability of milestone achievement and the associated revenue constraint; any resulting adjustments would be recorded on a cumulative catch-up basis, thus reflected in our financial statements in the period of adjustment.
(c) Service Revenue: We receive fees under certain arrangements for (i) sales and marketing services, (ii) supply chain services, (iii) research and development services, and (iv) clinical trial management services.
Our rights to receive payment for these services may be established by (1) a fixed-fee schedule that covers the term of the arrangement, so long as we meet ongoing performance obligations, (2) our completion of product delivery in our capacity as a procurement agent, (3) the successful completion of a phase of drug development, (4) favorable results from a clinical trial, and/or (5) regulatory approval events.
We consider whether revenue associated with these service arrangements is reportable each period, based on our completed services or deliverables (i.e., satisfied “performance obligations”) during the reporting period, and the terms of the arrangement that contractually result in fixed payments due to us. The promised service(s) within these arrangements are distinct and explicitly stated within each contract, and our customer benefits from the separable service(s) delivery/completion. Further, the nature of the promise to our customer as stated within the respective contract is to deliver each named service individually (not a transfer of combined items to which the promised goods or services are inputs), and thus are separable for revenue recognition.
(ii) Cash and Cash Equivalents
Cash and cash equivalents consist of bank deposits and highly liquid investments with maturities of three months or less from the purchase date.
(iii)(ii) Marketable Securities
Our marketableMarketable securities consist of our holdings in equity securities (beginning January 1, 2018 - see Note 3(a))(including mutual funds), bank CDs, government-related debt securities, and corporate debt securities. For equity securities and mutual funds, and bank certificates of deposit (“Bank CDs”). Beginning January 1, 2018, ourany realized andgains (losses) or unrealized (loss) gains on marketable securities(losses) are includedrecognized in “other income (expense), net” onwithin the accompanying Consolidated Statements of Operations. Prior to January 1, 2018, our unrealized (loss)Debt securities and bank CDs are classified as “available-for-sale” investments and (1) realized gains were included(losses) are recognized in “other comprehensive (loss) income” on our accompanyingincome (expense), net” within the Consolidated Statements of Comprehensive Loss.

(all tabular amounts presented in thousands, except share, per share, per unit,Operations and number(2) unrealized gains (losses) are recognized as a component of years)




(iv) Accounts Receivable
Our accounts receivable are derived from our product sales and license fees, and do not bear interest. The allowance for doubtful accounts is management’s best estimate of“accumulated other comprehensive loss” within the amount of probable credit losses in our existing accounts receivable. Account balances are charged off against the allowance after appropriate collection efforts are exhausted.
(v) Inventories
We value our inventory at the lower of (i) the actual cost of its purchase or manufacture, or (ii) its net realizable value. Inventory cost is determined on the first-in, first-out method. We regularly review our inventory quantities in process of manufacture and on hand. When appropriate, we record a provision for obsolete and excess inventory to derive its new cost basis, which takes into account our sales forecast by product and corresponding expiry dates of each product lot.
Manufacturing costs of drug products that are pending U.S. Food and Drug Administration ("FDA") approval are fully expensed through “research and development,” on the accompanying Consolidated Statements of Operations.Stockholders’ Equity.
(vi)(iii) Property and Equipment, Net

Our property and equipment, net, is stated at historical cost, and is depreciated on a straight-line basis over an estimated useful life that corresponds with its designated asset category. We evaluate the recoverability of “long-lived assets”long-lived assets (which includes property and equipment) whenever events or changes in circumstances in our business indicate that the asset’s carrying amount may not be recoverable through our on-going operations.
(vii) Goodwill and Intangible Assets
Our goodwill representsrecoverable. Recoverability is measured by a comparison of the carrying amount to the net undiscounted cash flows expected to be generated by the asset group. An impairment loss would be recorded for the excess of our business acquisition costnet carrying value over the estimated fair value of the netasset impaired. The fair value is estimated based on expected discounted future cash flows or other methods such as orderly liquidation value based on assumptions of asset class and observed market data. An orderly liquidation value is the amount that could be realized upon liquidation, given a sufficient amount of time to find a purchaser for a sale of assets acquired in their existing condition and location, as of a specific date, and assuming the corresponding transaction. Goodwill has an indefinite accounting lifesale is to market participants who can utilize such assets in their highest and is therefore not amortized. Instead, goodwill is evaluated for impairment on an annual basis (as of each October 1st), unless we identify impairment indicators that would require earlier testing.
We evaluatebest use. The orderly liquidation values are applied against the recoverability of indefinite-lived intangible assets at least annually, or whenever events or changes in our business indicate that an intangible asset’s (whether indefinite or definite-lived) carrying amount may not be recoverable. Such circumstances could include, but are not limited to the following:
(a) a significant decrease in the market value of an asset;
(b) a significant adverse change in the extent or manner in which an asset is used; or
(c) an accumulation of costs significantly in excessvalues of the amount originally expected forassets and the acquisition of an asset.
Intangible assets with finite useful lives are amortized over their estimated useful lives on a straight-line basis. We review these assets for potential impairment if/when facts or circumstances suggest thatloss is measured as the difference between the liquidation value and the carrying value of these assets may not be recoverable.the assets.
(viii)See Note 4(d) for further discussion related to impairments that occurred during the year ended December 31, 2020. There were no impairments recorded during the year ended December 31, 2021.
(iv) Stock-Based Compensation
Stock-based compensation expense for equity awards granted to our employees and members of our Board of Directors is recognized on a straight-line basis over each award’s vesting period. Recognized compensation expense is net of an estimated forfeiture rate, representing the percentage of awards that are expected to be forfeited prior to vesting, though is ultimately adjusted for actual forfeitures. We use the Black-Scholes option pricing model to determine the fair value of stock options and stock appreciation rights (as of the date of grant) that have service conditions for vesting. We use the Monte Carlo valuation model to value equity awards (as of the date of grant) that have combined market conditions and service conditions for vesting.
F-10


Notes to Consolidated Financial Statements
(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)
The recognition of stock-based compensation expense and the initial calculation of stock option fair value requires uncertain assumptions, including (a) the pre-vesting forfeiture rate of the award, (b) the expected term that the stock option will remain outstanding, (c) our stock price volatility over the expected term (and that of our designated peer group with respect to certain market-based awards), and (d) the prevailing risk-free interest rate for the period matching the expected term.
With regard to (a)-(d): We above: we estimate forfeiture rates based on our employees’ overall forfeiture history, which we believe will be representative of future results. We estimate the expected term of stock options granted based on our employees’ historical exercise patterns, which we believe will be representative of their future behavior. We estimate the volatility of our

F-12

Notes to Consolidated Financial Statements
(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)




common stock on the date of grant based on the historical volatility of our common stock for a look-back period that corresponds with the expected term. We estimate the risk-free interest rate based upon the U.S. Department of the Treasury yields in effect at award grant, for a period equaling the expected term of the stock option.
(ix) Foreign Currency Translation
Our foreign subsidiaries’ separate financial statements are stated in their functional currencies (i.e., local operating currencies). To create the accompanying Consolidated Financial Statements, we translate the assets and liabilities of our subsidiaries to U.S. dollars at the rates of exchange in effect at the reported balance sheet date; revenues and expenses are translated using the monthly average exchange rates during the reported period. Unrealized gains and losses from these translations are included in “accumulated other comprehensive (loss) income” in the accompanying Consolidated Balance Sheets.
We record foreign currency-based transactions (i.e., when not denominated in the functional currency of our transacting legal entity) at the prevailing exchange rate on the date of the transaction. Resulting unrealized foreign exchange gains and losses from these unsettled transactions are included in “accumulated other comprehensive (loss) income” in the accompanying Consolidated Balance Sheets.

All unrealized foreign exchange gains and losses associated with our intercompany loans are included in “accumulated other comprehensive (loss) income” in the accompanying Consolidated Balance Sheets, as these loans with our foreign subsidiaries are not expected to be settled in the “foreseeable future.”
(x)(v) Basic and Diluted Net Loss per Share
We calculate basic and diluted net loss per share using the weighted average number of common shares outstanding during the periods presented. In periods of a net loss, basic and diluted loss per share are the same. For the diluted earnings per share calculation, we adjust the weighted average number of common shares outstanding to include only dilutive stock options, warrants, and other common stock equivalents outstanding during the period.period to the extent that they are dilutive.
(xi)There were 13.5 million shares and 9.6 million shares of outstanding securities (including stock options, restricted stock units, stock appreciation rights, and performance awards) as of December 31, 2021 and 2020, respectively, that were excluded from the calculation of diluted net loss per share because their inclusion would have been anti-dilutive.
(vi) Income Taxes
Deferred tax assets and liabilities are recorded based on the estimated future tax effects of temporary differences between the tax basis of assets and liabilities and amounts reported in the financial statements, as well as operating losses and tax credit carry forwards using enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. Realization of deferred tax assets is dependent upon future earnings, the timing and amount of which are uncertain.
We have recordedapply an estimated annual effective tax rate (“ETR”) approach for calculating a tax provision for interim periods. Our ETR differs from the U.S. federal statutory tax rate primarily as a result of nondeductible expenses and the impact of a valuation allowance to reduceon our deferred tax assets, which we record because we believe that, based upon a weighting of positive and negative factors, it is more likely than not that these deferred tax assets will not be realized. If/when we were to determine that our deferred tax assets are realizable, an adjustment to the corresponding valuation allowance would increase our net income in the period that such determination was made.
In the event that we are assessed interest and/or penalties from taxing authorities that have not been previously accrued, such amounts would be included in “(provision) benefit“benefit for income taxes”taxes from continuing operations” within the accompanying Consolidated Statements of Operations infor the period in which we received the notice was received.notice.
(xii)(vii) Research and Development CostsExpenses
Our research and development costs are expensed as incurred. Research and development costs consist primarily of salaries, benefits, and other staff-related costs including associated stock-based compensation, laboratory supplies, clinical trial and related clinical manufacturing costs, costs related to manufacturing preparations, fees paid to other entities that conduct certain research and development activities on our behalf and payments made pursuant to license agreements. Clinical trial and other development costs incurred (see Note 17(c)), orby third parties are expensed as certainthe contracted work is performed. We accrue for costs incurred as the services are being provided by monitoring the status of activities and the invoices received from our external service providers. We adjust our accruals as actual costs become known. Where contingent milestone payments become contractuallyare due to our licensors, as triggered bythird parties under research and development or license agreements, the achievement ofmilestone payment obligations are expensed when the clinical or regulatory events.milestone results are achieved.
(xiii)(viii) Fair Value Measurements
We determine measurement-date fair value based on the proceeds that would be received through the sale of the asset, or that we would pay to settle or transfer the liability, in an orderly transaction between market participants. We utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. Fair

value measurements are based on a three-tier hierarchy that prioritizes the inputs used to measure fair value. These tiers include the following:

F-13

Notes to Consolidated Financial Statements
(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)




Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that are publicly accessible at the measurement date.
Level 2: Observable prices that are based on inputs not quoted on active markets, but that are corroborated by market data. These inputs may include quoted prices for similar assets or liabilities or quoted market prices in markets that are not active to the general public.
Level 3: Unobservable inputs are used when little or no market data is available.
(ix) Recently Issued Accounting Standards
There are several new accounting pronouncements issued by the FASB, which we don’t believe had or will have a material impact on our consolidated financial statements.

NOTE 4. BALANCE SHEET ACCOUNT DETAIL
The composition of selected financial statement captions that comprise the accompanying Consolidated Balance Sheets are summarized below:
(a) Cash and Cash Equivalents and Marketable Securities
As of December 31, 2018 and December 31, 2017, our “cash and cash equivalents” were held with major financial institutions. Our “marketable securities” primarily relate to our equity holdings in CASI Pharmaceuticals, Inc. (“CASI”), as defined below.
We maintain cash balances in excess of federally insured limits with reputableselect major financial institutions. To a limited degree, theThe Federal Deposit Insurance Corporation (FDIC) and other third parties insure a fraction of these investments. However,deposits. Accordingly, these investmentscash deposits are not insured against the possibility of a substantial or complete loss of earnings or principal and are inherently subject to the credit risk related to the continued credit worthiness of the underlying issuer and general credit market risks. We manage such risks in our portfolio by investing in highly liquid, highly-rated instruments, and limit investing in long-term maturity instruments.corresponding financial institution.
Our investment policy requires that purchased investments in marketable securities may only be in highly-rated and liquid financial instruments which are primarily U.S. treasury bills or treasury-backed securities, and also limits our investments in securitiesholdings of any single issuer (excluding any debt or equity securities that may be received from our strategic partners in connection with an out-license arrangement, as discussed in Note 11)arrangement).


The carrying amount of our equity securities, money market funds, and Bankbank CDs approximates their fair value (utilizing “Level 1” or “Level 2” inputs - see Note 2(xiii)) because of our ability to immediately convert these instruments into cash with minimal expected change in value.

(f)Manufacturing equipment was comprised of our owned eflapegrastim production equipment on location at our contract manufacturer. As of December 31, 2020, we determined that we would no longer proceed with the technology transfer and validation of a second manufacturing source for eflapegrastim and communicated this decision to the second source manufacturer.We had invested significant capital to prepare this facility for production.Due to the decision to halt this work, we determined that the value of certain eflapegrastim production equipment had a carrying amount in excess of the anticipated recoverable value as there would be no future cash flows from these assets other than through the sale of this equipment. We determined the fair value of these assets under an orderly liquidation value method, and based on the valuation performed we recorded an impairment of $19.7 million to our carrying value for this equipment, which was recorded as research and development expense for the year ended December 31, 2020 within the Consolidated Statements of Operations. During the year ended December 31, 2021, this equipment was surrendered in connection with the termination of our agreement with our second source manufacturer and we recorded incremental research and development expense of $2.9 million. Fair value was based on observable market data (“Level 2”). Due to the specialized nature of this production equipment, adjustments to observable market data were applied (“Level 3”).

In November 2018, we made a $2.7 million payment to Medac related to the FDA approval of KHAPZORY for its commercial sale. This amount was capitalized to "KHAPZORY distribution rights" during the fourth quarter of 2018 and will be amortized through December 31, 2019 (see Note 17(b)(xvi)).

(2)On February 20, 2015, the U.S. District Court for the District of Nevada found the patent covering FUSILEV to be invalid, which was upheld on appeal. On April 24, 2015, Sandoz began to commercialize a generic version of FUSILEV. This represented a “triggering event” under applicable GAAP in evaluating the value of our FUSILEV distribution rights as of March 31, 2015, resulting in a $7.2 million impairment charge (non-cash) in the first quarter of 2015. We accelerated amortization expense recognition for the remaining net book value of FUSILEV distribution rights. Effective December 2018, FUSILEV has been discontinued and we are no longer selling this product. We have since transitioned to marketing KHAPZORY for the same indications as FUSILEV.

(3)On May 29, 2013, we amended our FOLOTYN collaboration agreement with Mundipharma. As a result of the amendment, Europe and Turkey were excluded from Mundipharma’s commercialization territory, and their royalty rates and milestone payments to us were modified. This constituted a change under which we originally valued the FOLOTYN out-license as part of business combination accounting, resulting in an impairment charge (non-cash) of $1.0 million resulted from this amendment.

6. STOCK-BASED COMPENSATION
2018 Long-Term Incentive Plan Overview
We have one1 active stockholder-approved stock-based compensation plan, the 2018 Long- TermLong-Term Incentive Plan (the “2018 Plan”), which. In June 2018, the 2018 Plan replaced our former 2009 Incentive Award Plan (the "2009 Plan"“2009 Plan”) in June 2018.. Under the 2018 Plan, we may grant incentive stock options, non-qualified stock options, restricted stock awards restrictedand units, incentive and nonqualified stock units,options, performance unit awards, stock appreciation rights, and other stock-based awards.awards to employees, consultants, and members of our Board of Directors. Stock-based awards generally vest one-third on the first anniversary of the date of grant, and in equal annual installments thereafter over the remaining two years vesting period. Stock options must generally be exercised, if at all, no later than 10 years from the date of grant. In the event of a change in control, all award types with the exception of performance unit awards, will vest in full effective immediately prior to the consummation of the change in control. For performance unit awards, if a change in control occurs prior to the end date and the participant remains employed prior to the change in control, the shares vest based on the achievement of the performance goals as of the date of which the change in control occurs.
The stated maximum numberavailability of shares of our common stock available for issuance under the 2018 Plan at inception was 9.5 million shares. The number of shares of common stock that may be issued under the 2018 Plan may not exceed 9.5is 18 million shares, plus any shares that become eligibleexcept for issuance under the 2018 Plan because ofadditional availability provided on a one-for-1 basis for awards formerly issued under the 2009 Plan that are terminated, forfeited, cancelled or expire unexercised. AsAwards issued under the 2018 Plan reduce share availability on a one-to-1 basis for stock options and on a 1.5-to-one basis for restricted stock awards and restricted stock units. Accordingly, as of December 31, 2018, 17.62021, 4.4 million sharesawards were available for grant inclusiveunder the 2018 Plan, assuming all were issued in the form of aforementioned rollovers from our 2009 Plan. stock options, but would be reduced to 3.0 million awards available for grant if all were issued in the form of restricted stock.
It is our policy that before stock is issued through the exercise of stock options, we must first receive all required cash payment for such shares (whether through an upfront cash exercise or net-settlement exercise). At the time of vesting of restricted stock, by our policy, requisite shares are automatically sold on the open market by our designated broker to the extent required to cover the employee’s federal and state taxes due.
Stock-based awards are governed by agreements between us and the recipients. Incentive stock options and nonqualified stock options may be granted under the 2018 Plan at an exercise price of not less than 100% of the fair market value of our common stock on the respective date of grant and in some casesfor certain recipients may not be less than 110% of such fair market value with respect to Incentive Stock Options ("ISOs").value. The grant date is generally the date the terms of the award are approved by the Compensation Committee of theour Board of Directors.
Stock-based awards generally vest at 25% to 33% on the first anniversary following the date of grant, or for new hires, the first anniversary of their initial date of employment. Awards generally vest annually thereafter on a straight-line basis over three to four years. Stock options must generally be exercised, if at all, no later than 10 years from the date of grant. Upon termination of employment, vested stock options may generally be exercised based on the option termination rules including the following: six months after the date of termination upon retirement; twelve months after the date of termination upon disability or death; ninety days after the date of termination for all other terminations (though whether vested or unvested, stock options of the employee recipient are immediately forfeited upon termination for "Cause", as defined in the 2018 Plan).
Employee Stock Purchase Plan
Under the terms of our 2009 Employee Stock Purchase Plan (the “ESPP”), eligible employees can purchase common stock through scheduled payroll deductions. The purchase price is equal to the closing price of our common stock on the first or last day of the offering period (whichever is less), minus a 15% discount. We use the Black-Scholes option-pricing model, in

F-22

Notes to Consolidated Financial Statements
(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)




combination with the discounted employee price, in determining the value of ESPP expense to be recognized during each offering period. A participant may purchase a maximum of 50,000 shares of common stock during a six-month offering period, not to exceed $25,000 worth of stockat full market value on the offering date during each plan year.
As of December 31, 2018,2021, a total of 8.98.2 million shares of common stock are authorized and remain available for issuance under the ESPP. Beginning on January 1, 2010, and each January 1st thereafter, the number of shares of common stock available for issuance under the ESPP shall automatically increase by an amount equal to the lesser of (i) one million1000000 shares or (ii) an amount determined by the ESPP administrator. However, in no event shall the number of shares of common stock available for future sale under the ESPP exceed 10 million shares, subject to capitalization adjustments occurring due to dividends, splits, dissolution, liquidation, mergers, or changes in control.
Stock-Based Compensation Expense Summary
We report our stock-based compensation expense (inclusive of our incentive stock plan and employee stock purchase plan, and 401(k) contribution matching program)plan) in the accompanying Consolidated Statements of Operations based on the assigned department of the recipient.

Forfeitures are estimated at the time of grant and are prospectively revised if actual forfeitures differ from those estimates. We estimate forfeitures of stock options using the historical exercise behavior of our employees. For purposes of this estimate, we have applied an estimated forfeiture rate of 15%, 14%,11% and 11%15% for the years ended December 31, 2018, 2017,2021 and 2016,2020, respectively.
Valuation Assumptions – Restricted Stock and Stock Options
The grant-date fair value per share for restricted stock awards was based upon the closing market price of our common stock on the award grant-date.
The fair value of stock options granted was estimated at the date of grant using the Black-Scholes option-pricing model. The following assumptions were used to determine fair value for the stock awards granted in the applicable year:

Authorized Stock
In June 2018, our stockholders approved an amendment and restatement of our Certificate of Incorporation to reflect an increase in the number of authorized shares of our common stock from 175 million shares to 300 million shares. In addition to the increase in the authorized number of shares of common stock, the amendment eliminates designated series of preferred stock that are obsolete and are no longer outstanding or issuable, including Series B Junior Participating Preferred Stock and Series E Convertible Voting Preferred Stock.

A stockholder rights agreement will not prevent takeovers at a full and fair price, but rather is designed to deter coercive takeover tactics and to encourage anyone attempting to acquire our company to first negotiate with our Board of Directors.
On March 27, 2018, we entered into a Second Amendment to Rights Agreement which had the effect of suspending the Stockholders Rights Agreement as of March 30, 2018, though it will expire2018. On December 13, 2020, the Stockholder Rights Agreement expired under its termsterms.

10. BUSINESS COMBINATIONS AND CONTINGENT CONSIDERATION
(a) Acquisition of Talon Therapeutics, Inc.
Overview of Talon AcquisitionApril 2019 ATM Agreement.
On July 17, 2013,13, 2021, we purchased all offiled a shelf registration statement with the outstanding shares of common stock of Talon Therapeutics, Inc. (“Talon”SEC on Form S-3, which was declared effective by the SEC on July 21, 2021 (the “Registration Statement”). Through the acquisition of Talon, we gained worldwide rights to MARQIBO. The Talon purchase consideration consisted of (i)Registration Statement registered an aggregate upfront cash amount of $11.3 million, (ii) issuance of 3 million shares of our common stock, then equivalent to $26.3 million (based on a closingoffering price of $8.77 per share on July 17, 2013),up to $300 million of securities that may be issued and (iii) the issuance of a contingent value right (“CVR”) initially valued at $6.5 million.
The CVR was valued using a valuation model that probability-weights expected outcomes (rangingsold by us from 50%time to 100%) and discounts those amounts to their present value, using an appropriate discount rate (these represent unobservable inputs and are therefore classified as Level 3 inputs – see Note 2 (xiii)). The CVR has a maximum payout of $195 million if all sales and regulatory approval milestones are achieved, as summarized below:
$5 million upon the achievement of net sales of MARQIBO in excess of $30 million in any calendar year
$10 million upon the achievement of net sales of MARQIBO in excess of $60 million in any calendar year
$25 million upon the achievement of net sales of MARQIBO in excess of $100 million in any calendar year
$50 million upon the achievement of net sales of MARQIBO in excess of $200 million in any calendar year
$100 million upon the achievement of net sales of MARQIBO in excess of $400 million in any calendar year
$5 million upon receipt of marketing authorization from the FDA regarding Menadione Topical Lotion
Talon CVR Fair Value as of December 31, 2018 and December 31, 2017
The CVR fair value will continue to be evaluated on a quarterly basis. Current and future changes in its fair value results from the likelihood and timing of milestone achievement and/or the corresponding discount rate applied thereon. Adjustments to the CVR fair value are recognized within “change in fair value of contingent consideration related to acquisitions” in the accompanying Consolidated Statements of Operations.

(b) Acquisition of Rights to EVOMELA and Related Contingent Consideration
Overview of Acquisition of Rights to EVOMELA
In March 2013, we completed the acquisition of exclusive global development and commercialization rights to Captisol-enabled®, propylene glycol-free MELPHALAN (which we market as “EVOMELA”) for use as a conditioning treatment prior to autologous stem cell transplant for patients with MM. We acquired these rights from CyDex, a wholly-owned subsidiary of Ligand, for an initial license fee of $3 million, and assumed responsibility for EVOMELA's then-ongoing clinical and regulatory development program. We accounted for this transaction as a business combination, which required that assets acquired and liabilities assumed be recognized on the balance sheet at their fair values as of the transaction date.
We are required to pay Ligand additional amountstime, including up to an aggregate $60offering price of $150 million upon the achievement of annual net sales thresholds (exclusive of the $6 million milestone payment triggered in March 2016, as discussed below), however, we do not expect to achieve these sales thresholds based on our estimated market size for this product and our projected market share at the time of the acquisition and to date. We also must pay Ligand royalties of 20% on our net sales of EVOMELA in all territories.
Our EVOMELA royalty obligation and sales-based milestones are jointly treated as part of an "executory contract" (as defined under GAAP) thatcommon stock (which amount is connected with an at-market supply agreement for Captisol that was executed concurrently with this acquisition (requiring the continuing involvement of CyDex). As a result, our royalty and sales-based milestone arrangements are treated as separate transactions, distinct from the consideration for the EVOMELA rights. Our royalty expenses are reported through "cost of sales" on our Consolidated Statement of Operationsincluded in the same period of our recognized revenue for$300 million aggregate offering price set forth in the product sale.
Consideration Transferred
The acquisition-date fair value of the consideration transferred consisted of the following:
Cash consideration$3,000
Ligand Contingent Consideration4,700
Total purchase consideration$7,700
Fair Value Estimate of Asset Acquired and Liability Assumed
The total purchase consideration is allocated to the acquisition of the net tangible and intangible assets based on their estimated fair values as of the transaction date. The allocation of the total purchase price to the net assets acquired is as follows:
EVOMELA IPR&D rights$7,700
We estimated the fair value of the in-process research and development using the income approach. The income approach uses valuation techniques to convert future net cash flows to a single present value (discounted) amount. We applied our net cash flow projections for EVOMELA over 10 years and a discount rate of 25%, taking into account our estimates of future incremental earningsbase prospectus) that may be achieved upon regulatory approvalissued and commercialization of the product(s). The fair value of the Ligand Contingent Consideration (as defined below) liability was determined using the probability of success and the discounted cash flow method of the income approach (representing unobservable "Level 3" inputs (see Note 2(xiii))for regulatory and sales-based milestones due to Ligand upon achievement).
In March 2016, the FDA approved EVOMELA, triggering a $6 million milestone payment to Ligand ("Ligand Contingent Consideration") that was paid in April 2016. "EVOMELA IPR&D" of $7.7 million was reclassified in April 2016 to

(c) Allos Acquisition
We acquired Allos Therapeutics, Inc. ("Allos") in September 2012 for cash consideration of $205.2 million and assumed its FOLOTYN distribution rights (see Note 16). We accounted for this transaction as a business combination, which required that assets acquired and liabilities assumed be reported on our balance sheet at their fair values as of the transaction date. We have no ongoing contingent consideration obligations from this transaction.

11. OUT-LICENSE OF MARQIBO, ZEVALIN, & EVOMELA IN CHINA TERRITORY
Overview of CASI Out-License
In September 2014, we executed three perpetual out-license agreements for ZEVALIN, MARQIBO, and EVOMELA (“CASI Out-Licensed Products”) with CASI, a publicly-traded biopharmaceutical company (NASDAQ: CASI) with a primary focus on the China market (collectively, the “CASI Out-License”). Under the CASI Out-License, we received CASI common stock and a secured promissory note; CASI gained the exclusive rights to distribute these drug products in greater China (which includes Taiwan, Hong Kong and Macau).
CASI is responsible for the development and commercializationlaunch of these drugs including the submission of import drug registration applications to regulatory authorities and conducting any confirmatory clinical studies in greater China. We will provide CASI with future commercial supply of the CASI Out-Licensed Products under typical market terms.
CASI Ownership at December 31, 2018
Under certain conditions that expired in December 2017, we had a right to purchase additional shares of CASI common stock in order to maintain our post-investment ownership percentage. During 2017 and 2016, we acquired an additional 1.5 million and 4.6 million CASI common shares at par value, respectively. Our aggregate holding of 11.5 million common shares as of December 31, 2018, represented an approximate 12.1% ownership in CASI, with a fair market value of $46.4 million (see Note 3(a)).
Proceeds Received in 2014
The proceeds we received in 2014, and its fair value on the CASI Out-License execution date, consisted of the following:
CASI common stock (5.4 million shares)$8,649
(a)
CASI secured promissory note, net of fair value discount ($1.5 million face value and 0.5% annual coupon)1,310
(b)
Total consideration received, net of fair value discount$9,959

Notes to Consolidated Financial Statements
(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)




(a) Value determined based on the September 17, 2014 closing price of 5.4 million shares of CASI common stock on the NASDAQ Capital Market of $1.60 per share.

(b) Value estimated using the terms of the $1.5 million promissory note, the application of a synthetic debt rating based on CASI’s publicly-available financial information, and the prevailing interest yields on similar public debt securities as of September 17, 2014. This promissory note has been reclassified in the accompanying Consolidated Balance Sheets as of December 31, 2018 to "other receivables" (presented within current assets) from "other assets" (presented within non-current assets) due to its maturity date (as amended) of September 17, 2019.

(c) Presented within “license fees and service revenue” in the accompanying Consolidated Statements of Operations for the year ended December 31, 2015 (see below).
In addition, CASI will be responsible for paying any royalties or milestones that we are obligated to pay to our third-party licensors resulting from the achievement of certain milestones and/or sales of CASI Out-Licensed Products, but only to the extent of the greater China portion of such royalties or milestones.
License Fee Revenue Recognized in 2015
The $9.7 million value of the upfront proceeds (undiscounted, and net of certain foreign exchange adjustments) from CASI were recognized in 2015 within “license fees and service revenue.” The delayed timing of this revenue recognition corresponded with the execution of certain supply agreements with CASI for ZEVALIN, MARQIBO, and EVOMELA. These agreements allow CASI to procure CASI Out-Licensed Products directly from approved third parties, and in such case, do not require our future involvement for its commercial supply.
12. OUT-LICENSE OF ZEVALIN IN CERTAIN EX-U.S. TERRITORIES
In November 2015, we entered into an out-license agreement with Mundipharma AG ("Mundipharma") for its commercialization of ZEVALIN in Asia (excluding India and Greater China), Australia, New Zealand, Africa, the Middle East, and Latin America (including the Caribbean). In return, we received $18 million (comprisedhiring of $15 million received in December 2015personnel, building inventory supply and $3 million received in January 2016). Of these proceeds, $15 million was recognizedequipment purchases), completing acquisitions of assets, businesses, or securities, and reported within "license fees and service revenue" in the fourth quarter of 2015, and the remaining $3 million payment was recognized in full by June 30, 2017.
In April 2018, we received $2 million due to Mundipharma’s achievement of a specified sales milestone which was recognized in the first quarter of 2018 and reported within “license fees and service revenue” on our accompanying Consolidated Statements of Operations for the year ended December 31, 2018 (see Note 5). Mundipharma is required to reimburse us for our payment of royalties due to Bayer Pharma AG (“Bayer”) from its ZEVALIN sales - see Note 17(b)(ii).
13. OUT-LICENSE OF ZEVALIN, FOLOTYN, BELEODAQ, AND MARQIBO IN CANADA TERRITORY
On January 8, 2016, we entered into a strategic partnership with Servier Canada, Inc. ("Servier") for the out-licenses of ZEVALIN, FOLOTYN, BELEODAQ, and MARQIBO. We received $6 million in upfront payments in the first quarter of 2016 which was recognized within "license fees and service revenue" in the accompanying Consolidated Statements of Operations for the year ended December 31, 2016.
In November 2018, we received a $1 million milestone receipt from Servier upon the approval of FOLOTYN in Canada (see Note 17(b)(xv)). We will also receive additional development milestone payments if/when achieved, and a high single-digit royalty on their sales of these products.
14. CO-PROMOTION ARRANGEMENT WITH EAGLE PHARMACEUTICALS
In November 2015, we executed an agreement with Eagle Pharmaceuticals, Inc. ("Eagle") whereby designated members of our sales force concurrently marketed up to six of Eagle's products (along with our products). This arrangement was in return for fixed monthly payments (aggregating $12.8 million), and variable sales-based milestones from Eagle over an 18 month

F-32



contract term from January 1, 2016 through June 30, 2017 (the "Eagle Agreement"). On July 1, 2017 our sales force ceased marketing Eagle products and the Eagle Agreement expired under its terms.
The fixed receipts from Eagle for our sales activities, as well as reimbursements of third-party marketing services, are recognized within "license fees and service revenue" on our accompanying Consolidated Statements of Operations, and was $0, $4.7 million, and $9.1 million, for the years ended December 31, 2018, December 31, 2017, and December 31, 2016, respectively. No sales-based milestones were achieved in the current or prior periods.
An allocation of costs of our sales personnel that were dedicated to the Eagle Agreement are reported within "cost of service revenue" on our accompanying Consolidated Statement of Operations, as are reimbursed costs for Eagle marketing activities; these were an aggregate of $0, $4.2 million, and $7.9 million for the years ended December 31, 2018, December 31, 2017, and December 31, 2016, respectively.
15. CONVERTIBLE SENIOR NOTES
Overview of 2013 Convertible Notes
On December 17, 2013, we entered into an agreement for the sale of $120 million aggregate principal amount of 2.75% Convertible Senior Notes (equaling 120,000 notes, denominated in $1,000 principal units). the "2013 Convertible Notes." As of December 31, 2018 and December 31, 2017, $0 and $38.2 million of debt principal was outstanding, respectively. Maturity of the 2013 Convertible Notes occurred on December 15, 2018, and substantially all of these notes were converted into our common stock at a rate of 95 shares per $1,000 principal units, with an in-the-money conversion price of $10.53 per common share.
Proceeds and Conversion Hedge
We received net proceeds of $115.4 million in December 2013 for the sale of the 2013 Convertible Notes, after deducting banker and professional fees of $4.6 million. We used a portion of these net proceeds to simultaneously enter into “bought call” and “sold warrant” transactions with Royal Bank of Canada (collectively, the "Conversion Hedge"). We recorded the Conversion Hedge on a net cost basis of $13.1 million, as a reduction to “additional paid-in capital” within our Consolidated Balance Sheets, and under applicable GAAP, were not marked-to-market through earnings or comprehensive income.
We entered into these Conversion Hedge transactions to reduce the potential dilution to our stockholders and/or offset any cash payments that we would be required to make in excess of the principal amount, upon the conversion of the 2013 Convertible Notes (in the event that the market price of our common stock was greater than the conversion price). The strike price of the “bought call” was equal to the conversion price and conversion rate of the 2013 Convertible Notes (at such time, it matched the 11.4 million common shares into which the holders could convert the 2013 Convertible Notes); the strike price of our “sold warrant” is $14.03 per share of our common stock, and was also for 11.4 million common shares (reduced by partial unwinding of these instruments in 2016 and 2017, as discussed below).
Open Market Purchases of 2013 Convertible Notes and Conversion Hedge Unwind in December 2016 and October 2017
In December 2016, we completed two open market purchases of our 2013 Convertible Notes, aggregating 9,963 note units (equivalent to $10 million principal value) for $9 million. We recognized an aggregate book loss of $25 thousand on the retirement of these 2013 Convertible Notes (based on its carrying value under GAAP), which is included in "other (expense) income, net" on the Consolidated Statements of Operations for the year ended December 31, 2016. Concurrent with these two open market purchases in December 2016, we concurrently unwound a portion of our previously sold warrants and previously purchased call options (that were part of our Conversion Hedge described below) for aggregate net proceeds of $21 thousand. We recorded a corresponding net increase to "additional paid-in capital" in the Consolidated Balance Sheets as of December 31, 2016.
In October 2017, we completed an additional open market purchase of our 2013 Convertible Notes, aggregating 69,472 note units (equivalent to $69.5 million principal value) for $27.3 million in cash and 5.4 million newly-issued shares of our common stock, then worth $73 million. We recognized a book loss of $0.8 million on the retirement of these 2013 Convertible Notes (based on its carrying value under GAAP), which was included in "other (expense) income, net" on the Consolidated Statements of Operations for the year ended December 31, 2017.
Concurrent with this open market purchase in October 2017, we also unwound a portion of the previously sold warrants and previously purchased call options that were part of our Conversion Hedge for aggregate net proceeds of $5.8 million. We

16. FOLOTYN LICENSE AGREEMENT AND DEVELOPMENT LIABILITY
As a result of our acquisition of Allos on September 5, 2012 (see Note 10(c)), we assumed a strategic collaboration agreement with Mundipharma (as amended and/or restated, the “Mundipharma Collaboration Agreement”), as well as certain FOLOTYN clinical development obligations (the "FOLOTYN Development Liability").
Overview of Mundipharma Collaboration Agreement
Under the Mundipharma Collaboration Agreement, we retained full commercialization rights for FOLOTYN in the United States and Canada, with Mundipharma having exclusive rights to commercialize FOLOTYN in all other countries in the world. On May 29, 2013, the Mundipharma Collaboration Agreement was amended and restated, in order to modify: (i) the scope of the licensed territory, (ii) milestone payments, (iii) royalty rates, and (iv) drug development obligations. In connection with the amendment and restatement of the Mundipharma Collaboration Agreement, we received a one-time $7 million payment from Mundipharma for certain research and development activities to be performed by us.working capital purposes.
As a result of the amendment and restatement of the Mundipharma Collaboration Agreement, (a) Europe and Turkey were excluded from Mundipharma’s commercialization territory, (b) we may receive regulatory milestone payments of up to $16 million, and commercial progress and sales-dependent milestone payments of up to $107 million (see Note 17(b)(vii) for July 2017 achievement), (c) we will receive tiered double-digit royalties based on net sales of FOLOTYN within Mundipharma’s licensed territories, and (d) we and Mundipharma will each bear our own FOLOTYN development costs. Effective as of May 1, 2015, we modified the Mundipharma Collaboration Agreement to revise the conditions for our exercise of the option to gain

commercialization rights in Switzerland from Mundipharma, as well as royalties payable to us (in the tiered double-digits) on Mundipharma's net sales in Switzerland.
FOLOTYN Development Liability
The fair value of the FOLOTYN Development Liability within the accompanying Consolidated Balance Sheets was estimated using the discounted cash flow model. The unobservable inputs (i.e., "Level 3" inputs - see Note 2(xiii)) in this valuation model that have the most significant effect on these liabilities include (i) estimates of research and development personnel costs needed to perform the research and development services contractually required, (ii) estimates of expected cash outflows to third parties for these clinical services and supplies during the expected period of performance through 2031, and (iii) an appropriate discount rate for these expenditures. These inputs are reviewed by management on a quarterly basis for continued applicability.
We adjust this liability at each quarter-end, with corresponding adjustments for incurred costs recorded as credits to “research and development” expense in our accompanying Consolidated Statements of Operations.

17.NOTE 7. FINANCIAL COMMITMENTS & CONTINGENCIES AND KEY LICENSE AGREEMENTS
(a) Facility and Equipment Leases
Overview
In the ordinary course of our business, we enter into leases with unaffiliated parties for the use of (i) office and research facilities and (ii) office equipment. Our current leases have remaining terms ranging from less than one to five years and none include any residual value guarantees, restrictive covenants, term extensions, or early-termination options.

We lease our principal executive office in Henderson, Nevada under a non-cancelable operating lease expiringwhich expired on October 31, 2021.2021 and was extended through October 31, 2022. We also lease our research and development facility in Irvine, California under a non-cancelable operating lease expiring July 31, 2022, in addition to several other administrative office leases. EachWe entered into a new office facility lease agreement contains scheduledin Boston under a non-cancelable operating lease expiring in December 31, 2024.

Our facility leases have minimum annual rents, payable monthly, and some carry fixed annual rent increases whichincreases. Under some of these arrangements, real estate taxes, insurance, certain operating expenses, and common area maintenance are accounted for on a straight-line basis. Our total rental expensereimbursable to the lessor. These amounts are expensed as incurred, as they are variable in 2018, 2017,nature and 2016 was $1.6 million, $1.6 million, and $1.5 million, respectively.
Adoption of New Lease Accounting Standard, Effective January 1, 2019
In February 2016, the FASB issued ASU 2016-02, which amends the FASB Accounting Standards Codification and creates Topic 842, Leases (“Topic 842”). Topic 842 will become effective for us beginning January 1, 2019, and requires us (as a lessee) to recognize a "right-of-use asset" and a "lease liability" on our balance sheet for all leases (with the exception of leases less than 12 months) at the lease commencement date. The lease liability will be measured as the present value of the unpaid lease payments and the right-of-use asset will be derivedtherefore excluded from the calculationmeasurement of theour reported lease asset and liability adjusted for any prepayments or incentives. In July 2018, the FASB issued discussed below. As of December 31, 2021 and 2020, we had no sublease arrangements with us as lessor, and no finance leases, as defined in ASU 2018-11, 2016-02, Leases (Topic 842)Targeted Improvements, amending certain aspects of this new accounting standard. The amendment allows an additional optional transition method whereby an entity records a cumulative effect adjustment to the opening retained earnings balance in the year of adoption, without restating prior periods. (“Topic 842”).

We plan to elect the package of practical expedients available under the transition provisions of the new guidance, including (i) not reassessing whether expired or existing contracts contain leases, (ii) lease classification, and (iii) not revaluing initial direct costs for existing leases. Additionally, we plan to elect the practical expedient which allows for the aggregation of lease and non-lease components of underlying asset classes, as well as the short-term lease exemption. We will elect the optional transition approach to not apply the new lease standard in the comparative periods presented and the package of practical expedients available under the transition provisions in ASU 2018-11.

Under the new lease classification criterion, we currently do not have any finance or embedded leases. Our operating leases solely relate to (1) our executive, administrative, and research and development office facilities and (2) certain office equipment. Our January 1, 2019 adoption of Topic 842 will result in the initial reporting of "right-of-use assets" and "lease liabilities" on our Consolidated Balance Sheets of approximately $4.4 million and $4.4 million, respectively.

The recorded asset and liability associated with each lease is amortized over the respective lease term using the effective interest rate method. During the year ended December 31, 2021 and 2020, we recognized$1.8 million and $0, respectively, of additional right-of-use assets in exchange for lease liabilities.

We elected to not separate “lease components” from “non-lease components” in our measurement of minimum payments for our facility leases and office equipment leases. Additionally, we elected to not recognize a lease asset and liability for a term of 12 months or less.

(b) In/Out Licensing Agreements and Co-Development Arrangements
Overview
The in-license agreements for our commercialized and development-stage drug products provide us with territory-specific rights to their manufacture and distribution (including further sub-licensing/out-licensing rights). We are generally responsible for all related clinical development costs, patent filings and maintenance costs, marketing costs, and liability insurance costs. We also may enter into out-license agreements for territory-specific rights to these drug products which include one or more of: upfront license fees, royalties from our licensees’ sales, and/or milestone payments from our licensees’ sales or regulatory achievements. For certain drug products, we may enter into cost-sharing arrangements with licensees and licensors.
We are also obligated to make specified milestone payments to our licensors upon the achievement of certain regulatory and sales milestones, and to pay royalties based on our net sales of all in-licensed products. We also enter into out-licenseDepending on the milestone achievement type and whether the product has been approved, we will either (a) capitalize the value to “intangible assets” in the Consolidated Balance Sheets or (b) recognize the payment value within “research and development” or “cost of sales” on the Consolidated Statements of Operations. The liability relating to the payment due to the licensor will be recognized in the earliest period that we determine the respective milestone achievement is probable or occurs.
The most significant remaining agreements for territory-specific rights to our drug products which include one or more of: upfront license fees, royalties from our licensees’ sales, and/or milestone payments from our licensees’ sales or regulatory achievements. For certain development-stage drug products, we may enter into cost-sharing arrangementsassociated with our licensees and licensors.
Our most significant of these agreements, andoperations, along with the key financial terms and our corresponding accounting and reporting conventions for each, are summarized below:as follows:
(i) ZEVALIN U.S.: In-Licensing and development in the U.S.
In December 2008, we acquired rights to commercialize and develop ZEVALIN in the United States as the result of a transaction with Cell Therapeutics, Inc. (“CTI”) through our wholly-owned subsidiary, RIT Oncology LLC (“RIT”). In accordance with the terms of assumed contracts, we were required to meet specified payment obligations, including a milestone payment to Corixa Corporation of $5 million based on ZEVALIN sales in the United States. As of December 31, 2018 all the patents licensed from Corixa had expired under the terms of the agreement. Under the terms of the agreement, we are no longer obligated to pay United States net sales-based royalties in the low to mid-single digits to Genentech, Inc. and mid-teens to Biogen Inc.
(ii) ZEVALIN Ex-U.S.: In-License and Asset Purchase Agreement with Bayer Pharma
In April 2012, through our wholly-owned subsidiary, Spectrum Pharmaceuticals Cayman, L.P., we completed a €19 million acquisition of licensing rights to market ZEVALIN outside of the United States from Bayer. ZEVALIN is currently approved in approximately 40 countries outside the United States for the treatment of B-cell NHL, including countries in Europe, Latin America, and Asia.
We amended the agreement in February 2016, which adjusted our tiered royalty to Bayer from the single-digits to 20%. The term of the agreement, as amended, continues until the expiration of the last-to-expire ZEVALIN patent in the relevant country, or 15 years from the date of the first commercial sale of ZEVALIN in such country, whichever is longer.
(iii) ZEVALIN Ex-U.S.: Out-License Agreement with Dr. Reddy’s
In June 2014, we executed an exclusive License Agreement with Dr. Reddy’s Laboratories Ltd. (“Dr. Reddy’s”) for ZEVALIN distribution rights within India. The agreement term is 15 years from the receipt of pending approval of ZEVALIN from the Drug Controller General of India. In December 2014, upon our execution of a drug supply agreement, an upfront and non-refundable payment of $0.5 million was triggered and paid to us in February 2015. The recognition of the applicable portion of this upfront receipt is no longer reported on a straight line basis, within “license fees and service revenue” on our accompanying Consolidated Statements of Operations, due to the adoption of Topic 606 as of January 1, 2018 (see Note 2(i)). Additionally, sales and regulatory milestones, each aggregating $1.5 million (for a total of $3 million if both are achieved), are due to us upon Dr. Reddy’s achievement of such milestones, as well as a 20% royalty on its net sales of ZEVALIN in India.
(iv) ZEVALIN Ex-U.S.: Out-License Agreement with Mundipharma

Notes to Consolidated Financial Statements
(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)




In November 2015, we entered into an out-license agreement with Mundipharma for its commercialization of ZEVALIN in Asia (excluding India and Greater China), Australia, New Zealand, Africa, the Middle East, and Latin America (including the Caribbean). In return, we received $18 million (comprised of $15 million received in December 2015 and $3 million received in January 2016). Of these proceeds, $15 million was recognized within "license fees and service revenue" in the fourth quarter of 2015, and the remaining $3 million payment was recognized in full by June 30, 2017. Mundipharma is required to reimburse us for our payment of royalties due to Bayer from its Zevalin sales (see Note 17(b)(ii)).
In March 2018, Mundipharma achieved a specified sales milestone, resulting in a receipt of $2 million recorded within "license fees and service revenue" on our accompanying Consolidated Statements of Operations for the year ended December 31, 2018 (see Note 5).
(v) FUSILEV: In-License Agreement with Merck & Cie AG
In May 2006, we amended and restated a license agreement with Merck & Cie AG (“Merck”), which we assumed in connection with our March 2006 acquisition of the assets of Targent, Inc. This provided us with an exclusive license to use regulatory filings related to FUSILEV, and a non-exclusive license under certain patents and know-how to develop, manufacture, and sell FUSILEV in the field of oncology in North America.
The contractual royalty percentage on our FUSILEV net sales due to Merck is set at the mid-single digits; however, in September 2017, we paid Merck $2.6 million in full settlement of all royalty obligations under the agreement. As a result, we are no longer contractually obligated to pay any royalties or milestones for our net sales of FUSILEV.
(vi) FOLOTYN: In-License Agreement with Sloan-Kettering Institute, SRI International and Southern Research Institute
In December 2002, Allos entered into an in-license agreement for the drug now marketed as FOLOTYN with Sloan-Kettering Institute for Cancer Research, SRI International (SRI), and Southern Research Institute. We assumed this agreement when we acquired Allos in September 2012. The agreement provides for our exclusive worldwide rights to a portfolio of patents and patent applications related to FOLOTYN, though we are required to fund certain drug development programs. In addition, we pay graduated royalties to our licensors based on our worldwide annual net sales of FOLOTYN (including our sub-licensees). These royalties are 8% of annual worldwide net sales up to $150 million; 9% of annual worldwide net sales of $150 million through $300 million; and 11% of annual worldwide net sales in excess of $300 million. We are also obligated to remit a $3.5 million payment to SRI upon approval of FOLOTYN by the European Medicines Agency (“EMA”) approval of FOLOTYN. This regulatory milestone has not been met, and no amounts have been accrued in our accompanying Consolidated Balance Sheets for its potential achievement.
(vii) FOLOTYN: Out-License Agreement with Mundipharma
As a result of our acquisition of Allos (see Note 10(c)), we assumed “the Mundipharma Collaboration Agreement” as well as certain FOLOTYN clinical development obligations. Under the Mundipharma Collaboration Agreement, (see Note 16), we retained full commercialization rights for FOLOTYN in the United States and Canada, with Mundipharma having exclusive rights to commercialize FOLOTYN in all other countries in the world, except in Europe and Turkey. We are contractually entitled to receive regulatory and sales milestone payments from Mundipharma upon its achievement of such milestones, which aggregate $16 million and $107 million, respectively, as well as tiered double-digit royalties on Mundipharma's net sales.
In July 2017, FOLOTYN was approved in Japan for the treatment of adult patients with relapsed or refractory peripheral T-cell lymphoma ("PTCL"). Consequently, we received $3 million from Mundipharma in August 2017 for this milestone achievement. This amount was recognized within "license fees and service revenue" on our accompanying Consolidated Statements of Operations for the year ended December 31, 2017.
In August 2017, FOLOTYN was commercially launched in Japan. This triggered a contractual milestone of $2 million from Mundipharma. This amount was recorded within "license fees and service revenue" on our accompanying Consolidated Statements of Operations for the year ended December 31, 2017.
(viii) EVOMELA: In-License Agreement with Cydex Pharmaceuticals, Inc.
In March 2013, we completed the acquisition of exclusive global development rights to EVOMELA from CyDex, a wholly-owned subsidiary of Ligand (see Note 10(b)), and assumed responsibility for its then-ongoing clinical and regulatory development program. We filed a New Drug Application ("NDA") with the FDA in December 2015 for its use as a conditioning treatment prior to autologous stem cell transplant for patients with MM, and in March 2016, the FDA communicated its approval. Consequently, we made a $6 million contractual milestone payment to Ligand in April 2016. We reclassified $7.7

million from "EVOMELA IPR&D rights" to "EVOMELA distribution rights" which is presented within "intangible assets, net of accumulated amortization" (see Note 3(g)) within our accompanying Consolidated Balance Sheets as of December 31, 2018.
We are required to pay Ligand amounts of up to $60 million (exclusive of the $6 million milestone paid in April 2016), upon our achievement of specified net sales thresholds. We are also responsible to pay Ligand royalties of 20% on our net sales of EVOMELA in all territories.
(ix) MARQIBO: Acquisition of Talon Therapeutics, Inc. and Related Contingent Consideration Agreement
In July 2013, we completed the acquisition of Talon, through which we obtained exclusive global development and commercialization rights to MARQIBO (see Note 10(a)). As part of this acquisition, the former Talon stockholders have contingent financial rights that we have valued and presented on our accompanying Consolidated Balance Sheets as a $4.3 million and $6.2 million liability within “acquisition-related contingent obligations” as of December 31, 2018 and December 31, 2017, respectively. The maximum payout value of these contingent financial rights to the former Talon shareholders is $195 million, assuming we achieve all sales and regulatory approval milestones. In addition, we are contractually obligated to pay royalties in the single digits on our net sales of MARQIBO and a portion of sublicensing revenue may be due upon our receipt of such revenue for MARQIBO.
(x) QAPZOLA: License Agreements with Allergan, Inc. and NDDO Research Foundation
In October 2008, we entered into an exclusive development and commercialization collaboration agreement with Allergan, Inc. ("Allergan") for QAPZOLA pursuant to which Allergan paid us an up-front non-refundable fee of $41.5 million at execution (which we have recognized in full within “license fees and service revenue” by December 31, 2013).
Concurrently we also entered into a letter agreement with NDDO Research Foundation (“NDDO”), pursuant to which we agreed to pay NDDO the following in relation to QAPZOLA milestones: (a) upon FDA acceptance of our NDA, the issuance of 25,000 of our common shares (which occurred in March 2016 and the $0.1 million value of these shares was included in "research and development" expense for the year ended December 31, 2016), and (b) upon FDA approval, a one-time payment of $0.3 million (which has not yet been met, and no amounts have been accrued in our accompanying Consolidated Balance Sheets for its potential achievement).
In January 2013, we entered into a second amendment to the license, development, supply, and distribution agreement with Allergan. This amendment relieved Allergan of its development and commercialization obligations and resulted in our acquisition of its rights in the United States, Europe, and other territories, in exchange for our agreement to pay a tiered single-digit royalty on our sales of certain products containing QAPZOLA.
(xi) QAPZOLA: Collaboration Agreement with Nippon Kayaku Co. LTD.
In November 2009, we entered into a collaboration agreement with Nippon Kayaku Co., LTD. (“Nippon Kayaku”) for the development and commercialization of QAPZOLA in Asia, except North and South Korea (the “Nippon Kayaku Territory”). In addition, Nippon Kayaku received exclusive rights to QAPZOLA for the treatment of Non-Muscle Invasive Bladder Cancer in the Nippon Kayaku Territory, including Japan and China. Nippon Kayaku will conduct QAPZOLA clinical trials in the Nippon Kayaku Territory pursuant to a development plan. Further, Nippon Kayaku will be responsible for all expenses relating to the development and commercialization of QAPZOLA in the Nippon Kayaku Territory.
Under the terms of this agreement, Nippon Kayaku paid us an upfront fee of $15 million (which we recognized within “license fees and service revenue” in full by December 31, 2013). Under the terms of the agreement, we are entitled to receive $10 million and $126 million from Nippon Kayaku upon the achievement of certain regulatory and commercialization milestones, respectively (some of which are our responsibility to achieve). Nippon Kayaku is also obligated to pay us royalties on its net sales of QAPZOLA in the mid-teen digits.
(xii) BELEODAQ: In-License and Collaboration Agreement with Onxeo
In February 2010, we entered into an in-license and collaboration agreement with TopoTarget A/S (now Onxeo DK) (“Onxeo”), for the development and commercialization of BELEODAQ, as amended in October 2013. We paid Onxeo an upfront fee of $30 million (and agreed to additional payments described below) for rights in North America and India, with an option for China. We are contractually obligated to pay royalties in the mid-teen digits on our net sales of BELEODAQ.
All development and studies of BELEODAQ are conducted under a joint development plan (of which we fund 70% and Onxeo funds 30%). We have the final decision-making authority for all developmental activities in North America and India

(and China upon exercise of our option). Onxeo has final decision-making authority for all developmental activities in all other jurisdictions. In February 2014, upon FDA acceptance of our NDA, we were contractually obligated to issue Onxeo one million shares of our common stock and to make a $10 million milestone payment. The aggregate value of this milestone at achievement was $17.8 million, and was recognized within “research and development” expense in the first quarter of 2014.
In July 2014, we received approval from the FDA for BELEODAQ’s use for injection and treatment of relapsed or refractory PTCL. As a result, we made a second milestone payment to Onxeo of $25 million in November 2014. This amount was capitalized as "BELEODAQ distribution rights" and is presented within "intangible assets, net of accumulated amortization" (see Note 3(g)). We are also contractually obligated to pay Onxeo upon our achievements of other regulatory events and sales thresholds, up to $88 million and $190 million, respectively. These milestone amounts are not included within “total liabilities” in our accompanying Consolidated Balance Sheets.
(xiii) ROLONTIS:Eflapegrastim: Co-Development and Commercialization Agreement with Hanmi Pharmaceutical Co. Ltd

The Spectrum Pharmaceuticals, Inc. Deferred Compensation Plan (the “DC Plan”) is administered by the Compensation Committee of our Board of Directors and is intended to comply with the requirements of Section 409A of the Internal Revenue Code of 1986, as amended.
The DC Plan is maintained to provide special deferred compensation benefits for a select group of our employees (the “DC Participants”). DC Participants make annual elections to defer a portion of their eligible cash compensation which is then placed into their DC Plan accounts. We match a fixed percentage of these deferrals, and may make additional discretionary contributions.

(g) Litigation
We are involved from time-to-time with various legal matters arising in the ordinary course of business. These claims and legal proceedings are of a nature we believe are normal and incidental to a pharmaceutical business, and may include product liability, intellectual property, employment matters, and other general claims. We may also be subject to derivative lawsuits from time to time.
We make provisions for liabilities when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Such provisions are assessed at least quarterly and adjusted to reflect the impact of any settlement negotiations, judicial and administrative rulings, advice of legal counsel, and other information and events pertaining to a particular case. Litigation is inherently unpredictable. Although the ultimate resolution of these various matters cannot be determined at this time, we do not believe that such matters, individually or in the aggregate, will have a material adverse effect on our consolidated results of operations, cash flows, or financial condition.

Pursuant to our agreements with Hanmi, we hold worldwide rights (except for Korea, China, and Japan) to develop and commercialize eflapegrastim. The agreements with Hanmi contain typical license terms including, without limitation, indemnification rights in favor of the Company with respect to any claims of infringement from a third party with respect to our use of a licensed technology, product or compound pursuant to such agreements.

Related to the Bioverativ litigation, on December 20, 2021, we were named as respondents in an International Trade Commission (ITC) action filed in the ITC. The complaint alleged importation into the United States, the sale for importation, and the sale within the United States after importation of certain monomer-dimer hybrid immunoconjugates in violation of section 337 of the Tariff Act of 1930 (19 U.S.C. 1337).

On February 18, 2022, Spectrum, Hanmi and Bioverativ entered into a license and settlement agreement which included a stipulation to dismiss the Bioverativ litigation and withdraw the ITC complaint. On February 18, 2022, the ITC action against us was withdrawn, and on March 2, 2022, the Bioverativ case was dismissed by the U.S. District Court.

On November 1, 2021, 4 individuals and 1 entity filed competing motions to be appointed lead plaintiff and for approval of counsel in this putative securities class action. The plaintiffs seek damages, interest, costs, attorneys’ fees, and other unspecified equitable relief. We believe that these claims are without merit and intend to vigorously defend against these claims. Furthermore, as of December 31, 2018, the value of a potential settlement cannot be reasonably estimated given its highly uncertain nature.
EVOMELA Litigation
We obtained global development and commercialization rights to EVOMELA from CyDexCsaba v. Spectrum Pharmaceuticals, Inc., a wholly-owned subsidiary of Ligand Pharmaceuticals Incorporated, or CyDex, in March 2013.

At December 31, 20182021 and 2017,2020, we recorded a valuation allowance of $131.0$242.6 million and $86.0$192.5 million, respectively. The valuation allowance increased by $45.0$50.1 million and $0.8$39.5 million during 20182021 and 2017,2020, respectively. The increaseincreases in the valuation allowance in 20182021 and 2017 was2020 were mostly due to an increase in net operating loss carryforwards.
We had federal and state net operating loss carryforwards of approximately $452.0$746.6 million and $241.6$545.5 million, at December 31, 2018,2021, respectively. We have approximately $4.5$0.5 million of foreign loss carryforwards that will begin to expire in 2022.2039. The federal and state loss carry forwards began to expire in 2022 unless previously utilized, of which approximately $93.1 million of federal loss carryforwards expire in the next five years. Federal loss carryforwards generated in 2018 and 2017, respectively, unless previously utilized.beyond will be carried forward indefinitely. At December 31, 2018,2021, we had federal and state tax credits of approximately $15.2$19.0 million and $8.2$10.6 million, respectively. The federal tax credit carryovers begin to expire in 2027 unless previously utilized. The state research and development credit carryforwards have an indefinite carryover period.
As a result of the prior ownership changes, theOur utilization of certain net operating loss and research and development expense tax credit carryforwards, including those acquired in connection with the acquisition of Allos Therapeutics, Inc. in April 2012 and Talon Therapeutics, Inc. in July 2016, are subject to annual limitations under Sections 382 and 383 of the Internal Revenue Code of 1986 and similar state provisions. Any net operating losses or credits that would expire unutilized as a result of Section 382 and 383 limitations have been removed from the table of deferred tax assets and the accompanying disclosures of net operating loss and research and development carryforwards.
Accounting guidance clarifies the accounting for uncertain tax positions and prescribes a recognition threshold and measurement process for recording in the financial statements uncertain tax positions taken or expected to be taken in a tax return. Additionally, the authoritative guidance addresses the de-recognition, classification, accounting in interim periods and disclosure requirements for uncertain tax positions. Only tax positions that meet the more-likely-than-not recognition threshold at the effective date may be recognized.
The following tabular reconciliation summarizes the activity related to our unrecognized tax benefits:

We continue to believe that our tax positions meet the more-likely-than-not standard required under the recognition phase of the authoritative guidance. However, we consider the amounts and probabilities of the outcomes that can be realized upon ultimate settlement with the tax authorities and determined unrecognized tax benefits primarily related to credits should be established as noted in the summary rollforward above.
Approximately $0.2 million, $0.2$0.0 million and $0.7$0.1 million of the total unrecognized tax benefits as of December 31, 2018, 2017,2021 and 2016,2020, respectively, would reduce our annual effective tax rate if recognized. Additional amounts in the summary rollforward could impact our effective tax rate if we did not maintain a full valuation allowance on our net deferred tax assets.
We do not expect our unrecognized tax benefits to change significantly over the next 12 months. With a few exceptions, we are no longer subject to U.S. federal, state and local income tax examinations for years before 2014.2017. Our policy is to recognize interest and/or penalties related to unrecognized tax benefits in income tax expense in the consolidated statementsConsolidated Statements of operations.Operations.
On January 1, 2017, we adopted ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, on a prospective basis. Under ASU 2016-09, differences between the tax deduction for share based awards and the related compensation expenses recognized under ASC 718 are now accounted for as a component of the provision for income taxes. In addition, ASU 2016-09 eliminated the requirement that excess tax benefits from share based compensation reduce taxes payable prior to being recognized in the financial statements. As of December 31, 2016, we had cumulative excess benefits related to share based compensation of $2.7 million which had not been reflected as a deferred tax asset. As a result of the adoption of ASU 2016-09, the excess benefits were reclassified to our net operating loss carryover resulting in an increase in our deferred tax assets and valuation allowance of $2.7 million as of January 1, 2017. There is no impact to retained earnings as a result of the adoption of ASU 2016-09 on January 1, 2017.
On December 22, 2017,March 27, 2020, the U.S. government enacted comprehensivethe Coronavirus Aid, Relief, and Economic Security Act, or the CARES Act, a $2 trillion relief package comprised of a combination of tax legislation commonly referredprovisions and other stimulus measures. The CARES Act broadly provides entities tax payment relief and significant business incentives and makes certain technical corrections to as the 2017 Tax Cuts and Jobs Act, or the Tax Act. ChangesThe tax relief measures for entities include but are not limited to, a corporatefive-year net operating loss carry back, increased interest expense deduction limits,acceleration of alternative minimum tax rate decrease from 35% to 21% effective forcredit refunds, payroll tax years beginning in 2018, the transition of U.S international taxation from a worldwide tax system to a territorial system, which includes a new federal tax on global intangible low-taxed income (Global Minimum Tax or GMT),relief, and a one-time transitiontechnical correction to allow accelerated deductions for qualified improvement property. The CARES Act also provides other non-income tax benefits, including federal funding for a range of stabilization measures and emergency funding to assist those impacted by the COVID-19 pandemic.Similar legislation is being enacted in other jurisdictions in which the Company operates. ASC Topic 740, Income Taxes, requires the effect of changes in tax law be recognized in the period in which new legislation is enacted. The enactment of the CARES Act and similar legislation in other jurisdictions in which the Company operates is not expected to have a material impact on the mandatory deemed repatriationits consolidated financial position and results of cumulative foreign earningsoperations as of December 31, 2017. The Company calculated its best estimate2021.
Early Adoption of ASU 2019-12 — Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes
In March 2020, we elected to early adopt ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes,” which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. Based upon this early adoption, we were not required to calculate an income tax benefit for each quarter end period.
NOTE 9. DISCONTINUED OPERATIONS
Overview
In March 2019 we completed the sale of our 7 then-commercialized drugs, including FUSILEV, KHAPZORY, FOLOTYN, ZEVALIN, MARQIBO, BELEODAQ, and EVOMELA (the “Commercial Product Portfolio”) to Acrotech Biopharma LLC (“Acrotech”) (the “Commercial Product Portfolio Transaction”). Upon closing we received $158.8 million in an upfront cash payment. We are also entitled to receive up to an aggregate of $140 million upon Acrotech’s future achievement of certain regulatory milestones (totaling $40 million) and sales-based milestones (totaling $100 million) relating to the Commercial Product Portfolio.
Substantially all of the impactcontractual rights and obligations associated with the Commercial Product Portfolio were transferred to Acrotech at the closing of the Tax Act in its 2017 income tax provision in accordanceCommercial Product Portfolio Transaction. However, under the terms of this transaction we retained our trade “accounts receivable, net” and GTN liabilities included within “accounts payable and other accrued liabilities” associated with its understanding of the Tax Actour product sales made on and guidance available as of the date of the 10-K filing for the year ended December 31, 2017.
In addition, the SEC Staff issued SAB 118, which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companiesprior to complete the accounting under ASC 740. In accordance with SAB 118, a company mustFebruary 28, 2019.Accordingly, these Consolidated Financial Statements reflect the income tax effectscorresponding revenue-deriving activities and allocable expenses of those aspects of the Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. The provisional amounts were subject to revisions as the Company completed its analysis of the Tax Act, collected and prepared necessary data, and interpreted any additional guidance issued by the U.S. Treasury Department, Internal Revenue Service, or IRS, FASB, and other standard-setting and regulatory bodies. The measurement period expired as of December 31, 2018 and the Company's accounting for the Tax Act is complete. The changes in 2018 to provisional amounts recorded in 2017 for the effects of the Tax Act were not material.this commercial business within “discontinued operations”.

20. NEW REVENUE RECOGNITION STANDARD
As discussed in Note 2(i), Topic 606 became effective for us on January 1, 2018. We applied the “modified retrospective” transition method for the accounting of open contracts at implementation. This resulted in the recognition of an aggregate $4.7 million increase to our January 1, 2018 retained earnings (for the tax-effected cumulative impact of initially applying this new standard, with no adjustments to our prior period financial statements). Our prior periods continue to be presented in accordance with our historical revenue accounting practices under Topic 605.

21. SUBSEQUENT EVENT

Sale of Commercial Portfolio Distribution Rights for Proceeds Up to $300 million

On January 17, 2019, weCompany entered into a definitive asset purchase agreement for the saleSecurities Purchase Agreement with Hanmi, pursuant to which Hanmi purchased 12,500,000 shares of our FDA-approved product portfolio of FUSILEV, KHAPZORY, FOLOTYN, ZEVALIN, MARQIBO, BELEODAQ, and EVOMELA to Acrotech. Upon the closing of the Acrotech Transaction, we are entitled to receive up to $160 million in an upfront cash payment (of which $4 million will be held in escrow for six months). In addition, we expectcommon shares at a purchase price adjustmentof $1.60 per share, for certain ongoingan aggregate purchase price equal to $20 million.
In addition, the Company entered into amendments to the licensing agreements for both eflapegrastim and poziotinib, which resulted in the conversion of the upfront milestone payments for both products to deferred royalties. The royalty obligation for eflapegrastim changed to mid-single digits as a percent of sales for a specified period. The amended agreement eliminated poziotinib’s approval milestone payment in return for a supplemental royalty that will continue until the milestone is fully paid, based on the supplemental royalty. The companies also agreed to an amended supply arrangement that is expected to result in a lower cost of goods sold for Spectrum (See Note 7 Commitments and Contingencies for further discussion).
In addition, Hanmi has agreed to release the Company from a prior purchase obligation for eflapegrastim drug substance which will result in a reduction in accrued liabilities of $11.2 million with a corresponding reduction in research and development activitiesexpense.

We are also entitled to receive an aggregate $140 million upon Acrotech's achievement of certain regulatory and sales-based milestones relating to this product portfolio. We plan to reduce our staff by approximately 90 employees, the majority of which we expect to transition to Acrotech. The accounting recognition and financial reporting for the disposal of this commercial component of our business will be reflected in our financial statements in the period corresponding with its closing.Contents

Item 9A. Controls and Procedures
Our principal executive officer and principal financial officer have provided certifications filed as Exhibits 31.1 and 32.1, and 31.2, and 32.2, respectively. Such certifications should be read in conjunction with the information contained in this Item 9A for a more complete understanding of the matters covered by those certifications.
(a) 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 defined in Rule 13a-15(f) of the Exchange Act. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of the financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. This process includes those policies and procedures (i) that pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (ii) that receipts and expenditures are being made only in accordance with authorizations of our management and directors; (iii) that provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on our financial statements; and (iv) that provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP.

We continuously seek to improve the efficiency and effectiveness of our business operations and accompanying internal controls. An internal control system, no matter how well conceived and operated, can provide only reasonable assurance that its objectives are met. Because of its inherent limitations in any control system, no evaluation can provide absolute assurance that all control issues within a company have been detected. In addition, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of the internal control over financial reporting to future periodscontrols are subject to the risk that the internal control may become inadequateof inadequacy because of changes in business conditions and/or that the degree ofrisk that compliance with a company’s policies or procedures may deteriorate. deteriorate over time.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2018.2021. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013 framework) (“2013 COSO”).
Based on our management’s assessment, we have concluded that as of December 31, 2018,2021, our internal control over financial reporting was effective, as evaluated under the 2013 COSO criteria. Our independent registered public accounting firm, Deloitte & Touche LLP, has issued a report on our internal control over financial reporting. Deloitte & Touche LLP’s report appears within Item 9A in this Annual Report on Form 10-K and expresses an unqualified opinion on the effectiveness of our internal control over financial reporting.
(b) Disclosure Controls and Procedures
We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures as of December 31, 2018,2021, pursuant to Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures, as of such date, were effective.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the stockholders and Board of Directors of Spectrum Pharmaceuticals, Inc.
Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Spectrum Pharmaceuticals, Inc. and subsidiaries (the “Company”) as of December 31, 2018, based on the criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control-Integrated Framework (2013) issued by COSO.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2018, of the Company and our report dated February 28, 2019, expressed an unqualified opinion on those financial statements.

Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
