ITEM 1. BUSINESS
Item 1. Business
Overview
Zymeworks is a biotechnology company committed to the discovery, development, and commercialization of novel, multifunctional biotherapeutics. Zymeworks’ mission is to make a meaningful difference for people impacted by difficult-to-treat cancers and other serious diseases. Zymeworks’ complementary therapeutic platforms and fully integrated drug development engine provide the flexibility and compatibility to precisely engineer and develop highly differentiated antibody-based therapeutic candidates.
Our lead product candidate, zanidatamab, is a novel bispecific antibody that targets two distinct domains of the human epidermal growth factor receptor 2 (“HER2”). Zanidatamab’s unique binding properties result in multiple mechanisms of action that may enable it to address unmet need in patient populations with HER2-expressing cancers. In clinical trials, zanidatamab monotherapy and zanidatamab in combination with chemotherapy have been well tolerated with promising antitumor activity in patients with treatment-naive and heavily pretreated HER2-expressing cancers, including individuals whose disease had progressed on multiple prior treatment regimens that included HER2-targeted agents. Based on these data, a number of global multicenter clinical trials have been initiated to evaluate zanidatamab in specific indications and lines of therapy. These include pivotal clinical trials in (i) previously treated HER2 gene-amplified biliary tract cancers (“BTC”) and (ii) first-line locally advanced or metastatic HER2-positive gastroesophageal adenocarcinomas (“GEA”) in combination with chemotherapy with or without BeiGene, Ltd.’s (“BeiGene”) tislelizumab. These also include proof of concept trials in (i) first-line locally advanced or metastatic HER2-positive colorectal cancer (“CRC”), GEA, or BTC in combination with standard of care chemotherapy, (ii) first-line locally advanced or metastatic HER2-positive GEA in combination with tislelizumab and chemotherapy, (iii) first-line locally advanced or metastatic HER2-positive breast cancer in combination with docetaxel, (iv) previously treated locally advanced or metastatic HER2-positive, hormone receptor-positive breast cancer in combination with Pfizer’s Ibrance (palbociclib) and fulvestrant, (v) previously treated locally advanced or metastatic HER2-expressing cancers (including HER2-positive and HER2-low breast cancer) in combination with ALX Oncology Inc.’s (“ALX Oncology”) evorpacept (ALX148), and (vi) locally advanced (unresectable) and/or metastatic HER2-expressing cancers in Japanese patients. Zymeworks has entered into separate agreements with BeiGene and Jazz Pharmaceuticals Ireland Limited (a subsidiary of Jazz Pharmaceuticals plc, collectively referred to as “Jazz”), granting each of BeiGene and Jazz with exclusive rights to develop and commercialize zanidatamab in different territories. Through these agreements, Zymeworks has no funding obligations for current or future clinical studies or research and development spending and retains rights to receive potential regulatory and commercial milestones, as well as royalties for future net sales, pending approval in relevant regulatory jurisdictions. For additional information regarding these agreements with BeiGene and Jazz, see the section entitled “Strategic Partnerships and Collaborations” below.
Our second product candidate, zanidatamab zovodotin (formerly known as “ZW49”), combines the unique biparatopic antibody design of zanidatamab with our ZymeLink auristatin antibody-drug conjugate (“ADC”) technology, comprised of our proprietary cytotoxin (cancer cell-killing compound) and cleavable linker. We designed zanidatamab zovodotin to be a potential best-in-class HER2-targeting ADC to further address unmet need across a range of HER2-expressing cancers. In January 2023, we announced our intent to continue development of zanidatamab zovodotin at the recommended phase two dose (“RP2D”) of 2.5 mg/kg dosed every three weeks. Before the end of 2023, we expect to present additional data from our Phase 1 clinical trial that further supports this RP2D and commence enrollment in multiple Phase 2 studies.
We are also advancing a deep pipeline of preclinical product candidates and discovery-stage programs in oncology (including immuno-oncology agents) and other therapeutic areas with an emphasis on developing ADC and multi-specific antibody therapeutics (“MSAT”) candidates. Our pipeline of preclinical product candidates includes two lead programs, ZW191 and ZW171, for which we expect to submit investigational new drug (“IND”) applications in 2024, as well as multiple early-stage preclinical programs in development. The two lead programs are as follows:
•ZW191, our lead ADC candidate, is built using our Drug Conjugate platforms and uses our novel topoisomerase inhibitor (“TOPO1i”)-based payload technology targeting folate receptor alpha expressing ovarian, other gynecological, and non-small cell lung cancers. ZW191 was designed using an in-house generated monoclonal antibody with enhanced internalization characteristics in order to target high, mid, and low levels of folate alpha receptor expression; and
•ZW171, our lead multispecific candidate, is built using our Azymetric platform and is a novel 2 + 1 format T-cell engaging multispecific antibody targeting pancreatic, mesothelioma, ovarian, and other mesothelin (“MSLN”)-
expressing cancers. ZW171 has a unique geometry with two single-chain fragment variable arms targeting MSLN, and one fab arm targeting CD3 to redirect the body’s natural immune system to fight cancer cells.
Our proprietary capabilities and technologies include several modular, complementary therapeutic platforms that can be used in combination with each other and with existing approaches. This ability to layer technologies without compromising manufacturability enables us to engineer next-generation biotherapeutics with synergistic activity, which we believe will result in improved patient outcomes. Our platforms include:
•Azymetric, our multispecific antibody platform, which enables therapeutic antibodies to simultaneously bind multiple distinct locations on a target (known as an epitope) or to multiple targets. This is achieved by tailoring multiple configurations of the antibody’s Fab regions (locations on the antibody to which epitopes bind);
•Drug Conjugate Platforms, used to develop ADC candidates, are comprised of cytotoxins and the linker technologies used to couple these cytotoxins to tumor-targeting antibodies or proteins. These platforms can be used in conjunction with our other therapeutic platforms to increase safety and efficacy as compared to existing ADC technologies;
•EFECT, which enables finely tuned modulation (both up and down) of immune cell recruitment and function; and
•ProTECT, which enables tumor-specific activity that may reduce systemic toxicity and simultaneously enhances localized immune co-stimulation or checkpoint modulation that may increase efficacy.
Our protein engineering expertise and proprietary structure-guided molecular modeling capabilities enable these therapeutic platforms. Together with our internal antibody discovery and generation technologies, we have established a fully integrated drug development engine and toolkit capable of rapidly delivering a steady pipeline of next-generation product candidates in oncology and other therapeutic areas.
Our Strategy
Our goal is to use our experience and capabilities developing multifunctional therapeutics platforms, along with our proprietary protein engineering capabilities, to have a meaningful and positive impact on the lives of people living with difficult-to-treat cancers and other serious diseases with high unmet medical need.
To achieve this goal, we are focused on delivering substantial progress across five key areas of our business:
Zanidatamab Collaboration with Jazz Pharmaceuticals
Our collaboration agreement with Jazz entered into during the fourth quarter of 2022 represents an important component of our commercialization strategy for zanidatamab and our financial strategy for expanding and developing our product pipeline. Through December 31, 2022, we have received $375 million in proceeds from the Jazz collaboration and are eligible for reimbursement of ongoing zanidatamab-related costs in accordance with the development plan and budget. We also remain eligible to receive regulatory approval milestones of up to $525 million, commercial milestones of up to $862.5 million, and royalties of between 10% and 20% of future zanidatamab sales, pending regulatory approval of zanidatamab. In conjunction with Jazz, we plan to provide updates on progress towards regulatory filings, new clinical studies, and future clinical data releases, which includes the anticipated presentation of the full data set from our HERIZON-BTC-01 pivotal clinical trial in the first half of 2023 and our expectation to report top-line data from our HERIZON-GEA-01 pivotal clinical trial in 2024.
Zanidatamab Collaboration with BeiGene
Our collaboration agreements with BeiGene in the key Asia Pacific (APAC) regions (excluding Japan) are important given the high prevalence of BTC and GEA in the APAC region. To date, we have received approximately $60 million in upfront and milestone payments from the BeiGene collaboration as well as certain co-development funding for zanidatamab clinical studies. Through our collaboration with BeiGene on zanidatamab and zanidatamab zovodotin, we remain eligible to receive up to $390 million in additional development and commercial milestones together with tiered royalties of up to 20% of future product sales, pending regulatory approval. In conjunction with BeiGene, we plan to provide updates on progress towards regulatory filings in the APAC region, new clinical studies, and future clinical data releases.
Research and Early Development Programs
Our current scientific strategy provides for a broad and differentiated product pipeline of ADCs and multispecific antibody therapeutics to be developed from our technology platforms with the goal of five new IND applications by 2027. We expect to submit IND applications for our lead preclinical product candidates (ZW191 and ZW171) in 2024. During 2023, we expect to
nominate an additional product candidate for preclinical development with an anticipated IND filing in 2025. We plan to continue actively presenting and publishing additional data on our preclinical programs in 2023, with a focus on the American Association for Cancer Research (AACR) meeting scheduled for the second quarter. We expect to evaluate, and potentially enter into, additional multi-product collaborations and partnerships in 2023 and 2024 to expand the breadth of our research and early development programs. We plan to make additional investments during 2023 and 2024 in the size and capabilities of our research group in order to maintain the desired speed, quality, diversity, and novelty in our future product pipeline. Further, we also plan to evaluate external opportunities in adjacent research areas to expand our focus beyond the current technology platforms.
Zanidatamab Zovodotin
We plan to continue development of zanidatamab zovodotin at the RP2D of 2.5 mg/kg every three weeks and, before the end of 2023, we expect to present additional data from our ongoing Phase 1 clinical study that supports this RP2D. Based on the data generated to date from the Phase 1 clinical study, which has continued to enroll patients to gather additional data for zanidatamab zovodotin monotherapy, we plan to evaluate zanidatamab zovodotin as monotherapy and/or in combination with the current respective standards of care in multiple Phase 2 studies expected to commence enrollment in 2023. Based on our development efforts to date and in combination with the results of these planned clinical studies, we believe these results may provide the rationale for one or more registration-enabling studies of zanidatamab zovodotin before the end of 2025, which we would expect to undertake with a future collaboration partner.
Platform Licensing Portfolio
To date, we have received approximately $180.0 million in the form of non-refundable upfront and milestone payments from platform partnership and collaboration agreements, excluding amounts received related to zanidatamab or zanidatamab zovodotin. We continue to have revenue-generating strategic partnerships and collaborations with respect to our Azymetric, EFECT and Drug Conjugate therapeutic platforms with the following pharmaceutical companies: BeiGene, Celgene Corporation and Celgene Alpine Investment Co. LLC (now a Bristol-Myers Squibb company, “BMS”), GlaxoSmithKline Intellectual Property Development Limited (“GSK”), Daiichi Sankyo Co., Ltd. (“Daiichi Sankyo”), Janssen Biotech, Inc. (“Janssen”), LEO Pharma A/S (“LEO”), Iconic Therapeutics, Inc. (“Iconic”) (and through our relationship with Iconic, Exelixis, Inc. (“Exelixis”)), Merck Sharp & Dohme Research GmbH (“Merck”), and Atreca, Inc. (“Atreca”). During 2023 and 2024, we expect to earn additional milestone payments under certain of these agreements as products continue to advance in development, and we have the potential to receive additional payments in connection with any expansion or extension of these agreements.
Product Candidate Pipeline
We currently have two lead product candidates in clinical development and several product candidates in preclinical development that leverage our multiple therapeutic platforms to address areas of significant unmet medical need. Our lead product candidates, zanidatamab and zanidatamab zovodotin, utilize the Azymetric platform to address patient populations with HER2-expressing cancers. We are also actively advancing a diverse set of preclinical programs, which leverage one or more of our proprietary therapeutic platforms to create a deep pipeline of well-differentiated product candidates for oncology and other therapeutic areas.
Late-Stage Clinical: Zanidatamab
Overview
Zanidatamab, our lead product candidate, is currently being evaluated in Phase 1, Phase 2, and Phase 3 clinical trials, including certain ongoing pivotal clinical trials. It is a biparatopic antibody, based on our Azymetric platform, that can simultaneously bind two non-overlapping epitopes of HER2. Zanidatamab’s unique binding properties result in multiple mechanisms of action including HER2-receptor clustering, internalization, and downregulation; inhibition of growth factor-dependent and
-independent tumor cell proliferation; antibody-dependent cellular cytotoxicity and phagocytosis; and complement-dependent cytotoxicity. These combined mechanisms of action have led to promising antitumor activity in preclinical models of HER2-expressing cancers, including tumors resistant to trastuzumab (currently branded as Herceptin).
We have entered into separate agreements with BeiGene and Jazz, granting each of BeiGene and Jazz exclusive rights to develop and commercialize zanidatamab in different territories. Through these agreements, we have no funding obligations for current or future clinical studies or research and development spending and retain rights to receive potential regulatory and commercial milestones, as well as royalties for future net sales, pending approval in relevant regulatory jurisdictions.
Clinical Development of Zanidatamab
In clinical trials, zanidatamab monotherapy and zanidatamab in combination have been well tolerated with promising antitumor activity in patients with treatment-naive and heavily pretreated HER2-expressing cancers, including individuals whose disease had progressed on multiple prior treatment regimens that included HER2-targeted agents. Based on these data, a number of global multicenter clinical trials have been initiated to evaluate zanidatamab in specific indications and lines of therapy, as described above under “Overview.”
In June 2022, we, in conjunction with our Asia-Pacific partner BeiGene, presented Phase 1b/2 clinical data at the ASCO Annual Meeting. The two presentations included data on the first-line treatment of patients with HER2-positive metastatic gastric/ gastroesophageal junction adenocarcinoma using zanidatamab in combination with chemotherapy and BeiGene’s anti-PD1 tislelizumab and on the first-line treatment of patients with HER2-positive metastatic breast cancer who received zanidatamab plus chemotherapy. In 33 response-evaluable patients with advanced HER2-positive gastric/gastroesophageal junction adenocarcinoma treated with zanidatamab and tislelizumab in combination with the CAPOX chemotherapy regimen, the confirmed objective response rate (“cORR”) was 75.8% [95% CI: 57.7, 88.9]. The disease control rate (“DCR”) was 100% and duration of response ranged from 2.1+ to 18.2+ months. Twenty patients (61%) remained on study at the time of data cut-off. In 21 response-evaluable patients with advanced HER2-positive breast cancer treated with zanidatamab and docetaxel, the cORR was 90.5% [95% CI: 69.6, 98.8] with 15 patients (78.9%) having an ongoing response at the time of the data cut. The DCR was 95.2% [95% CI: 76.2, 99.9]. The median follow-up was 7.0 months (range 1.1-17.4 months) and the six-month progression-free survival rate was 95.2% [95% CI: 70.7, 99.3]. Overall, both combinations exhibited promising response rates and tolerability in patients.
In December 2022, we published in The Lancet Oncology our Phase 1 data (NCT02892123) in pre-treated patients with HER2-expressing solid tumors who received zanidatamab monotherapy. Eighty-six patients (22 patients with BTC, 28 patients with CRC and 36 patients with other solid tumors excluding GEA or breast cancer) demonstrated promising responses and zanidatamab was generally well tolerated in patients. Grade 1-2 diarrhea and infusion reactions were the most common reported treatment-related adverse events with no treatment-related deaths. In addition, 31 [37%; 95% CI 27.0, 48.7] of 83 evaluable patients had a cORR.
In December 2022, we presented Phase 2 clinical data at the San Antonio Breast Cancer Symposium. The presentation reported data from a clinical study of 45 patients with heavily pretreated HER2-positive, Hormone Receptor-positive (“HR-positive”) metastatic breast cancer who received zanidatamab in combination with palbociclib and fulvestrant. Patients had received prior regimens containing HER2-targeted agents including trastuzumab (100%), pertuzumab (80%), T-DM1 (98%), and other available options. In 36 efficacy-evaluable patients, treatment with zanidatamab in combination with palbociclib and fulvestrant resulted in a cORR of 33% [95% CI: 18.6, 51.0] and DCR of 92% [95% CI: 77.5, 98.2), and the majority of patients experienced a decrease in tumor size. The interim median progression-free survival (“mPFS”) was 9.6 months [95% CI: 7.2, 16.6] with seven patients still on study at the time of data cut-off (August 31, 2022). The regimen was generally well tolerated with expected rates of neutropenia, a known side effect of CDK4/6 inhibitors. The majority of patients with treatment-related adverse events experienced mild to moderate severity (Grade 1 or 2).
Also in December 2022, we announced positive top-line data in the HERIZON-BTC-01 pivotal Phase 2b trial of zanidatamab as monotherapy in previously treated HER2-amplified BTC patients. The top-line results showed that 41.3% [95% CI: 30.4, 52.8] of enrolled patients with HER2-amplified and expressing (IHC2+ and 3+) disease achieved a confirmed objective response as assessed by independent central review. The median duration of response was 12.9 months [95% CI: 5.95 to not reached]. The safety profile of zanidatamab in this trial was consistent with that observed in previously reported monotherapy studies, with no new safety signals identified. Full results from the pivotal trial are expected to be presented at a medical meeting in the first half of 2023.
In January 2023, we presented updated Phase 2 clinical data at the ASCO Gastrointestinal Cancers Symposium. The presentation included updated data from a clinical study evaluating zanidatamab in combination with standard of care chemotherapy in first-line HER2-expressing GEA patients. Patients had not received prior HER2-targeted agents or systemic treatment for metastatic GEA. A total of 46 patients with metastatic GEA were enrolled from 15 sites across the United States, Canada and South Korea. The data demonstrated zanidatamab combined with standard chemotherapy is a highly active treatment regimen for first-line therapy of HER2-positive metastatic GEA. In 42 patients evaluable for overall survival (“OS”) receiving zanidatamab in combination with chemotherapy, the 18-month OS rate was 84% [95% CI: 68, 93], the 12-month OS rate was 88% [95% CI: 73, 95], and the median OS had not yet been reached (with 26.5 months median duration of study follow-up). These data represent the first OS data presented for a zanidatamab containing regimen. Treatment with zanidatamab resulted in a cORR of 79% [95% CI: 63, 90], a DCR of 92% [95% CI: 79, 98], with three patients achieving complete response among 38 response-evaluable patients. The median duration of response was 20.4 months [95% CI: 8.3, NE] with an mPFS of
12.5 months [95% CI: 7.1, NE] with 17 patients having an ongoing response at the time of data cut-off. The regimen was manageable, tolerable and consistent with the observed safety profiles reported for other standard combination regimens for patients with HER2-positive GEA.
Zanidatamab is currently being evaluated in the following clinical trials:

Zanidatamab also received Orphan Drug designation for the treatment of BTC and gastric cancer, including cancer of the gastroesophageal junction, in the United States and for gastric cancer and BTC in the European
Union (“EU”). Zanidatamab has also been granted Breakthrough Therapy designation from the Center for Drug Evaluation in China for treating patients with BTC who have failed prior systemic therapies.
Early-Stage Clinical and Early Research and Development
The below table summarizes our early-stage clinical and early Research and Development candidates.
Zanidatamab Zovodotin: HER2-Targeted Bispecific ADC
Overview
Zanidatamab zovodotin, our second product candidate, is currently being evaluated in a Phase 1 clinical trial. It is a biparatopic anti-HER2 ADC developed based on Zymeworks’ proprietary Azymetric multispecific and ZymeLink ADC platforms and combines the unique design of zanidatamab with a proprietary cytotoxin and cleavable linker. Our cytotoxin destabilizes tubulin, a protein necessary for cell division, and therefore kills rapidly dividing cancer cells. In preclinical models, compared to certain approved HER2-targeted therapies, zanidatamab zovodotin mediates a superior therapeutic effect on HER2-expressing tumors through multiple potential mechanisms, including:
•increased maximum HER2 binding density;
•unique biparatopic-induced HER2 receptor clustering;
•increased HER2-mediated ADC internalization; and
•enhanced toxin-mediated cytotoxicity and tumor growth inhibition.
We are developing zanidatamab zovodotin to be a potential best-in-class HER2-targeting ADC for several indications characterized by HER2 aberrations, especially for patients whose tumors have progressed or are refractory to HER2-targeted agents and those that express lower levels of HER2 and are ineligible for treatment with other HER2-targeted therapies.
Preclinical Development of Zanidatamab Zovodotin
In preclinical studies, zanidatamab zovodotin demonstrated complete tumor regressions in a panel of high and low HER2-expressing patient-derived xenografts and promising efficacy in a model of breast cancer brain metastases. These results compared favorably when benchmarked against approved and leading HER2 ADCs in clinical development. In a repeat dose
toxicology study in non-human primates, zanidatamab zovodotin was well tolerated at 18 mg/kg, suggesting a broad therapeutic window.
Clinical Development of Zanidatamab Zovodotin
We are currently evaluating zanidatamab zovodotin as a monotherapy in a non-randomized, open-label Phase 1 clinical trial in patients with HER2 High breast, gastric and other HER2-expressing cancers, whose disease has progressed after all standard of care therapies. The primary objective of the Phase 1 clinical trial is to characterize the safety, tolerability, pharmacokinetics and maximum tolerated dose of zanidatamab zovodotin. The secondary objectives for the trial include evaluation of preliminary antitumor activity of zanidatamab zovodotin, as well as an exploration of potential biomarkers of response. Based upon the observed safety and activity, subsequent development may focus on patients with HER2 High breast cancer, HER2 High gastric cancer, other HER2 High cancers, as well as cancers with lower levels of HER2 expression, including breast cancer.
In September 2022, we presented preliminary Phase 1 trial results for zanidatamab zovodotin as monotherapy for the treatment of various HER2-positive tumors at the European Society for Medical Oncology (“ESMO”) Annual Congress. A total of 77 heavily pretreated patients were enrolled in this first-in-human trial, which was designed to determine the maximum tolerated dose of zanidatamab zovodotin, characterize its safety and tolerability, and evaluate anti-tumor activity in HER2-expressing cancers as monotherapy. The patients represented a variety of HER2-expressing cancers including breast, gastroesophageal, ovarian, endometrial, bladder, biliary tract, anal, colorectal, pancreatic and lung. At the time of the analysis, the maximum tolerated dose had not yet been reached. In the trial, zanidatamab zovodotin was shown to have a manageable and differentiated safety profile with the majority of adverse events being Grade 1 or 2 in severity. The majority of patients (20/29) had received prior HER2-targeted therapies with patients receiving a median of three (range 1 to 13) prior therapies in the metastatic setting, including a median of six (range 3 to 13) in metastatic breast cancer and four (range of 1 to 8) in metastatic GEA. In patients with HER2-positive cancers treated with zanidatamab zovodotin at 2.5 mg/kg Q3W (dose escalation + dose expansion), the cORR was 31% [95% CI: 15.3, 50.8] and the DCR was 72% [95% CI: 52.8, 87.3]. The Phase 1 clinical trial is ongoing and continues to enroll patients to study safety, tolerability and activity in various cohorts at the Q3W schedule. We expect to present updated results from this Phase 1 study before the end of 2023.
In January 2023, we announced our plans for the continued development of zanidatamab zovodotin at the RP2D of 2.5 mg/kg every three weeks and announced that by the end of 2023, we expect to present additional data from our clinical study that further supports this RP2D. Based on the data generated to date from the Phase 1 clinical study, which has continued to enroll subjects to gather additional data for zanidatamab zovodotin monotherapy, we plan to evaluate zanidatamab zovodotin as monotherapy and/or in combination with the current respective standards of care in multiple planned Phase 2 studies. Based on our development efforts to date and in combination with the results of these planned clinical studies, we believe these results may provide the rationale for one or more registration-enabling studies of zanidatamab zovodotin before the end of 2025, which we would expect to undertake with a future collaboration partner.
Other Preclinical Product Candidates
We maintain ongoing discovery efforts to identify and test new target combinations, product candidates and platform technologies that have the potential to address unmet medical needs. We have developed multiple preclinical product candidates targeting a combination of known and novel tumor antigens based on our platform technologies. All of these candidates remain unpartnered. We continue to focus on advancing multiple well-differentiated product candidates into clinical trials to build our pipeline portfolio as well as exploiting our protein engineering and ADC expertise to develop innovative product candidates.
As part of our early Research and Development day held in New York City in October 2022, we announced multiple preclinical product candidates, including two lead candidates, ZW191 and ZW171. Our lead ADC preclinical product candidate, ZW191, is a folate receptor alpha targeted ADC with a novel TOPO1i-based payload that we believe may be competitive in areas with high unmet medical need. Similarly, our lead multispecific preclinical product candidate, ZW171, a novel and differentiated MSLN-targeted bispecific T-cell engaging antibody generated utilizing our Azymetric bispecific platform, targets the potential treatment of patients in pancreatic, mesothelioma, ovarian, and other MSLN-expressing cancers. We expect to submit IND applications for ZW191 and ZW171 in 2024.
We expect to continue developing additional early-stage ADC and multispecific product candidates, such as ZW251, a glypican-3 targeted TOPO1i-based ADC, and ZW220, a NaPi2b targeted ADC with a TOPO1i-based payload, as well as additional preclinical product candidates currently in development.
Our Proprietary Therapeutic Platforms
Our expertise in protein engineering has enabled the development of our proprietary therapeutic platforms, a complementary suite of highly tailored biologics solutions. Our therapeutic platforms can be used alone or in combination to develop multifunctional fit-for-purpose biotherapeutics with bispecific capabilities (Azymetric), targeted cytotoxin payload delivery and linker technologies (Drug Conjugate Platforms), finely tuned immune function modulation (EFECT), and tumor-specific immune co-stimulation (ProTECT). The modular design and ease of use of our therapeutic platforms allow for the design and evaluation of multiple candidates with different formats to determine the optimal therapeutic combination early in development. We continue to leverage these therapeutic platforms to expand our pipeline of next-generation multispecific and ADCs that we believe could represent significant improvements to the standard of care in multiple cancer types and other serious diseases.
Azymetric Multispecific Antibody Platform
The Azymetric multispecific antibody platform is our foundation platform, which can produce either the backbone of our ADCs or be the base of our multispecific therapeutics that can be combined with both our trispecific T-cell engager (“TriTCE”) technology and our ProTECT platform to develop potential best-in-class trispecifics. The Azymetric platform consists of a library of proprietary amino acid substitutions that enable the transformation of monospecific antibodies into bispecific or trispecific antibodies, which gives them the ability to simultaneously bind two non-overlapping epitopes. The Azymetric platform enables the development of biotherapeutics with dual-targeting of receptors/ligands and simultaneous blockade of multiple signaling pathways, increasing tumor-specific targeting and efficacy while reducing toxicities and the potential for drug resistance. In preclinical studies, the dual targeting of Azymetric antibodies has demonstrated synergistic activity relative to the application of an equivalent dose of the corresponding monospecific antibodies. Azymetric multispecifics can also be engineered to enhance internalization of the antibody into the tumor cell and consequently increase the delivery of cytotoxins. Azymetric multispecifics retain the desirable drug-like qualities of monoclonal antibodies, including long half-life, stability and low immunogenic potential, which increases their probability of success. Azymetric multispecifics are also compatible with standard manufacturing processes with high production yields and purity.
The Azymetric platform is the foundation for the development of trispecific and trivalent antibodies. Our complementary suite of technologies can incorporate multiple targets and mechanisms of action within a single antibody-based therapeutic. To achieve efficacy and durability in a difficult tumor microenvironment, we have developed a TriTCE strategy that integrates checkpoint inhibition (“TriTCE-CPI”) and costimulatory technologies (“TriTCE-costim”). TriTCE-CPI technology is designed to navigate suppressive tumor microenvironments and enhance the activity of T-cell engagers through incorporation of a checkpoint pathway binder to restore and enhance T-cell engagement and overcome secondary resistance to provide durable responses. TriTCE-costim technology can increase T-cell fitness, activation and proliferation via tumor-dependent T-cell co-stimulation. Further, T-cell engager technologies can integrate with ProTECT, a technology built to mask an antibody arm to improve selectivity to minimize off-target, and mitigate on-target, adverse events.
Drug Conjugate Platforms
Our Drug Conjugate Platforms are a suite of proprietary cytotoxins (including both topoisomerase and microtubulin inhibiting toxins), stable linkers, and conjugation technologies that are compatible with and complementary to our product candidates and enable delivery of cytotoxins directly to target cells. We believe that our platforms provide multiple competitive advantages over existing ADC approaches, including optimized activity and tolerability profiles through increased drug delivery to target cells with reduced off-target effects, as well as improved pharmacokinetics and stability. Our Drug Conjugate Platforms can be used in conjunction with our other therapeutic platforms to potentially increase safety and efficacy as compared to existing ADC technologies.
EFECT Antibody Effector Function Modulation Platform
The EFECT platform consists of sets of modifications to the crystallizable fragment (“Fc”) region of antibodies that enable the selective modulation of recruited cytotoxic immune cells for diverse therapeutic applications. This allows us to rationally tailor the selective enhancement or suppression of immune effector function to optimize product candidates.
ProTECT Tumor-Specific Immune Co-stimulation Platform
The ProTECT platform is a novel conditionally active antibody technology that can simultaneously increase the tolerability and efficacy for therapeutics, thereby potentially enhancing therapeutic window and clinical utility. Functional, natural immunomodulatory heterodimers are introduced to sterically block antigen binding outside the tumor, enabling therapeutics with limited activity in normal healthy tissue, avoiding on-target, off-tumor toxicities. Once in the tumor microenvironment, specific proteases cleave and release one half of the functional block activating both the targeting antibody and the immunomodulatory function. The resulting activated multifunctional therapeutic enables immune modulation in concert with antigen binding, which enables an overall increase in the therapeutic window through selective tumor activity and enhanced potency.
Strategic Partnerships and Collaborations
The table below summarizes the stage of each of our partners’ most advanced publicly disclosed program.
Our novel product candidates, together with our combination of proprietary protein engineering capabilities and resulting therapeutic platform technologies, have enabled us to enter into a number of strategic partnerships, many of which were subsequently expanded in scope. Our strategic partnerships and collaborations provide us with the ability to accelerate clinical development of our product candidates in certain geographical regions and provide our strategic partners with access to components of our proprietary therapeutic platforms for their own therapeutics development. In addition, these strategic partnerships have provided us with non-dilutive funding as well as access to proprietary therapeutic assets, which increase our ability to rapidly advance our product candidates while maintaining commercial rights to our own therapeutics.
Through collaboration agreements with Jazz and BeiGene relating to our lead programs for zanidatamab and zanidatamab zovodotin, we have received over $435 million through December 31, 2022 in the form of non-refundable upfront payments and milestone payments. In addition, through these partnerships, we are eligible to receive up to $1.75 billion in potential regulatory, development and commercial milestone payments, as well as tiered royalties on potential future product sales, pending receipt of regulatory approval. These partnerships have provided us with a significant source of non-dilutive funding and provide for the future funding requirements for our lead asset, zanidatamab. These partnerships also leverage our partners’ commercial infrastructure, helping accelerate the development and expanding the potential reach of our lead product candidates.
To date, we have received approximately $180.0 million in the form of non-refundable upfront and milestone payments from platform partnership and collaboration agreements, excluding amounts received related to zanidatamab or zanidatamab
zovodotin. We continue to have revenue-generating strategic partnerships and collaborations with respect to our Azymetric, EFECT and Drug Conjugate therapeutic platforms with BeiGene, BMS, GSK, Daiichi Sankyo, Janssen, LEO, Iconic, Merck and Atreca. Under these revenue-generating strategic partnerships and collaboration agreements, we are eligible to receive up to $2.8 billion in preclinical and development milestone payments and up to $5.9 billion in commercial milestone payments, as well as tiered royalties on potential future product sales, pending regulatory approval. It is possible, however, that our strategic partners’ programs will not advance as currently contemplated, which would negatively affect the amount of development and commercial milestone payments and royalties on potential future product sales we may receive. Importantly, these partnerships include predominantly non-target-exclusive licenses for any of our therapeutic platforms, so we maintain the ability to develop therapeutics directed to many high-value targets utilizing our platforms.
Our strategic partnerships and collaborations include the following:
Jazz
In October 2022, Zymeworks BC entered into a License and Collaboration Agreement (the “Jazz Collaboration Agreement”) with Jazz, under which Jazz will have development and commercialization rights of zanidatamab throughout the world, but excluding existing territories already governed by Zymeworks BC’s agreement with BeiGene (the “Territory”). BeiGene has exclusive rights, pursuant to an agreement with Zymeworks BC dated November 26, 2018, as amended (the “BeiGene Agreement”), to commercialize zanidatamab in those countries that are excluded from the Territory.
Under the terms of the Jazz Collaboration Agreement, Zymeworks BC granted to Jazz an exclusive, royalty-bearing license, with the right to grant sublicenses, under certain of Zymeworks BC’s intellectual property, to research, develop, manufacture, and commercialize in the Territory pharmaceutical products containing or incorporating zanidatamab or certain related antibodies (such antibodies, collectively, “Licensed Antibodies” such pharmaceutical products, “Licensed Products”). Licensed Antibodies and Licensed Products expressly exclude all ADCs, including Zymeworks BC’s proprietary ADC, zanidatamab zovodotin. Zymeworks BC also granted to Jazz a non-exclusive license, with the right to grant sublicenses, under certain of Zymeworks BC’s intellectual property, to research, preclinically develop and manufacture Licensed Products outside the Territory for the sole purpose of furthering the development and commercialization of Licensed Products in the Territory.
Jazz granted Zymeworks BC certain licenses, under certain of Jazz’s intellectual property, to develop and commercialize Licensed Antibodies and Licensed Products outside the Territory, to conduct certain development and manufacturing activities with respect to the Licensed Products in the Territory, and to make and have made Licensed Antibodies for incorporation into zanidatamab zovodotin, for development and commercialization both in and outside the Territory. If the BeiGene Agreement is terminated, in whole or in part, Jazz has a right of first negotiation to develop or commercialize any Licensed Product in such countries. In November 2022, the waiting period under the United States Hart-Scott Rodino Antitrust Improvements Act of 1976 expired (such clearance, the “HSR Clearance”).
During the Term (as defined below), Jazz and its affiliates are prohibited from performing any clinical development of, or commercialization of, any pharmaceutical product containing a bispecific antibody directed to the ECD2 and ECD4 domains of HER2 in the Territory, other than Licensed Products. During the Term, Zymeworks BC and its affiliates are prohibited from performing any preclinical development (except for certain independent, internal preclinical development by Zymeworks BC or its affiliates) or clinical development of, or commercializing, any pharmaceutical product that is directed to HER2 in the Territory (each, a “Zymeworks Competing Product”), other than Licensed Products; provided that zanidatamab zovodotin is excluded from this restriction. Zymeworks BC retains the right to grant third parties rights to apply any of Zymeworks BC’s platforms to derive or generate, without any assistance from Zymeworks BC, antibodies directed to any biological target where Zymeworks BC is not aware of the identity of any such target, and Zymeworks BC retains the right to fulfill its obligations under agreements with its existing platform partners; provided, however, that Zymeworks BC cannot generate, or grant development or commercialization licenses to, Zymeworks Competing Products in new platform-based agreements entered into after the effective date of the Jazz Collaboration Agreement.
As between Jazz and Zymeworks BC, Jazz will be solely responsible for all development and commercial activities with respect to Licensed Products in the Territory, and all such development and commercial activities in the Territory shall be at Jazz’s sole cost and expense, except that Zymeworks BC shall be responsible for the continued conduct of clinical trials for zanidatamab initiated by Zymeworks BC prior to the execution of the Jazz Collaboration Agreement (collectively, the “Zymeworks Ongoing Studies”), including those clinical trials initiated by Zymeworks BC in South Korea, and filing of the first Biologics License Application for the Licensed Product (the “First BLA”), at Jazz’s cost and expense subject to the terms and conditions under the Jazz Collaboration Agreement. Following regulatory approval of the First BLA or earlier upon Jazz’s written request, Zymeworks BC will promptly transfer the First BLA to Jazz.
Jazz shall use commercially reasonable efforts to develop and obtain regulatory approval for a Licensed Product in certain major market countries for the treatment of certain diseases. Jazz will be the holder of regulatory approvals and regulatory
submissions for Licensed Products in the Territory, except with respect to the Zymeworks Ongoing Studies and the First BLA until it is transferred to Jazz.
Zymeworks BC will (either itself or through Zymeworks BC’s contract manufacturing organization) manufacture, and Jazz will purchase from Zymeworks BC, Jazz’s requirements of zanidatamab and Licensed Product until Jazz or Jazz’s contract manufacturer is approved to manufacture Licensed Antibody and Licensed Product, or until two years after the closing of the Jazz Collaboration Agreement (which closing occurred following receipt of the HSR Clearance), whichever is later. Thereafter, Zymeworks BC will manufacture for Jazz, and Jazz will purchase from Zymeworks BC, certain quantities of zanidatamab and Licensed Product, until such manufacture is fully transferred to Jazz, but no later than three years after closing. Supply of zanidatamab and Licensed Product shall be further set forth in separate clinical and commercial supply agreements to be executed by the parties.
Jazz shall be solely responsible for commercializing the Licensed Products in the Territory and use commercially reasonable efforts to commercialize in each specified major market country each Licensed Product that obtains regulatory approval in such country. Jazz shall conduct such commercialization at its sole cost and expense.
Under the Jazz Collaboration Agreement, Zymeworks BC received (i) a non-refundable $50.0 million upfront payment following receipt of HSR Clearance and delivery of licenses and technology transfer to Jazz and (ii) a further payment of $325.0 million following Jazz’s decision to continue the collaboration after readout of the top-line clinical data from HERIZON-BTC-01, as well as Zymeworks BC’s delivery of all data, analyses and other information set forth in the Jazz Collaboration Agreement. Jazz will reimburse Zymeworks BC for Zymeworks BC’s performance of development activities under the Jazz Collaboration Agreement in accordance with a development plan and budget. Zymeworks BC will be also eligible to receive up to an aggregate of $525.0 million in certain regulatory milestones payments and up to an aggregate of $862.5 million in potential commercial milestone payments, for total potential payments of up to $1.76 billion. Pending approval, Zymeworks BC is eligible to receive tiered royalties between 10% and 20% on annual net sales of Licensed Products in the Territory, with customary reductions in specified circumstances. Royalties are payable on a Licensed Product-by-Licensed Product and country-by-country basis until the latest of (i) ten years after the first commercial sale of such Licensed Product in such country, (ii) the expiration of the last valid licensed patent claim within the licensed Zymeworks BC intellectual property covering such Licensed Product in such country, and (iii) the expiration of regulatory exclusivity of such Licensed Product in such country.
Zymeworks BC shall solely own all inventions made by the parties solely or jointly that specifically relate to the composition of matter of zanidatamab and any invention made solely by Zymeworks BC and its affiliates. Jazz shall own all inventions made solely by Jazz. Inventions made jointly by the parties shall be owned jointly by the parties.
Unless terminated earlier, the term of the Jazz Collaboration Agreement will continue on a Licensed Product-by-Licensed Product and country-by-country basis until the expiration of the royalty term for such Licensed Product in such country (the “Term”). On a country-by-country basis, upon the expiration of the Term, the license granted to Jazz in such country shall become fully paid-up, royalty-free, perpetual, and irrevocable.
At any time, Jazz may terminate the Jazz Collaboration Agreement, in its entirety or on a region-by-region basis, by providing written notice of termination to Zymeworks BC. In the event that Jazz or its affiliates file or initiate a patent challenge against Zymeworks BC, Zymeworks BC may terminate the Jazz Collaboration Agreement unless such challenge is withdrawn, abandoned, or terminated following Jazz’s receipt of written notice from Zymeworks BC. Subject to certain conditions, either party may terminate the Jazz Collaboration Agreement in the event of an uncured material breach or insolvency of the other party.
Upon the termination of the Jazz Collaboration Agreement for any reason, all licenses and other rights granted to Jazz by Zymeworks BC shall terminate. Licenses granted by Jazz to Zymeworks BC shall continue following the effective date of termination, and Jazz shall grant to Zymeworks BC a non-exclusive, royalty-bearing and sublicensable license under certain intellectual property controlled by Jazz that either arises from the Jazz Collaboration Agreement or is used by or on behalf of Jazz in the development, manufacture, or commercialization of Licensed Products. If Jazz has the right to terminate the Jazz Collaboration Agreement because Zymeworks BC was in material breach of the Jazz Collaboration Agreement and did not timely cure such breach, Jazz may elect to have the Jazz Collaboration Agreement continue in full force and effect and all amounts thereafter payable by Jazz under the Jazz Collaboration Agreement will be reduced, and Jazz will have no further obligations to develop and commercialize each Licensed Product in each major market.
The Jazz Collaboration Agreement also includes certain other customary terms and conditions, including mutual representations and warranties, indemnification, and confidentiality provisions.

BMS
In December 2014, we entered into a collaboration agreement with Celgene (now BMS) to research, develop and commercialize bispecific antibodies generated through the use of our Azymetric platform. This agreement was expanded in 2018 to increase the number of programs from eight to ten and to extend BMS’s research period. Under the terms of the agreement, we granted BMS a right to exercise options to worldwide, royalty-bearing, antibody sequence pair-specific exclusive licenses to research, develop and commercialize certain licensed products. We received an upfront payment of $8.0 million and an expansion fee of $4.0 million. BMS has the right to exercise options on up to ten programs and if BMS opts in on a program, we are eligible to receive up to $164.0 million per product candidate (up to $1.64 billion for all ten programs), comprised of a commercial license option payment of $7.5 million, development milestone payments of up to $101.5 million and commercial milestone payments of up to $55.0 million. To date, BMS has exercised one commercial license option and we have received a total of $7.5 million in product candidate-specific payments. In addition, we are eligible to receive tiered royalties calculated upon the global net sales of the resulting products. BMS will have exclusive worldwide commercialization rights to products derived from the agreement if BMS elects to exercise a commercial license option for each product. After conclusion of BMS’s research period, BMS will be solely responsible for the research, development, manufacturing and commercialization of the products. In June 2020, our existing collaboration agreement with BMS was amended to expand the license grant to include the use of our EFECT platform for the development of therapeutic candidates and to extend the research term. We received an upfront expansion fee of $12.0 million and all other financial terms were unchanged. The agreement contains customary termination rights for BMS and us, including the right of BMS to terminate the agreement in its entirety or on a product-by-product basis in its sole discretion with advance notice to us. The agreement will terminate on a product-by-product and country-by-country basis upon the later of the expiration of the last-expiring patent related to the BMS licensed product, or ten years after the first commercial sale of the BMS licensed product in such a country. If BMS does not exercise its
option for the commercial license, the agreement will terminate on a product-by-product basis for which the option was not exercised.

Atreca
In April 2022, Atreca announced a licensing agreement with us to utilize our ZymeLink technology to develop novel ADCs. We recognized a $5.0 million research license fee payment in association with this licensing agreement in conjunction with future option exercise fees and development, regulatory, and commercial milestones as well as tiered royalties on net sales of any licensed products at single-digit royalty rates.
Intellectual Property
Our business success will depend significantly on our ability to:
•secure, maintain and enforce patent and other proprietary protection for our core technologies, inventions and know-how;
•obtain and maintain licenses to key third-party intellectual property owned by such third parties;
•preserve the confidentiality of our trade secrets; and
•operate without infringing upon valid, enforceable third-party patents and other rights.
We seek to secure and maintain patent protection for the composition of matter, manufacturing processes and methods of use for our drug candidates and for our underlying protein engineering capabilities and therapeutic platforms including Azymetric, EFECT, ZymeLink, ZymeCAD and ProTECT. We also utilize trade secrets, careful monitoring and limited disclosure of our proprietary information where patent protection is not appropriate. We also protect our proprietary information by ensuring that our employees, consultants, contractors and other advisors execute agreements requiring non-disclosure and assignment of inventions prior to their engagement. We intend to continue to expand our intellectual property holdings by seeking patent protection for new compositions of matter, new features and applications of our core therapeutic platforms, and innovative new therapeutic platforms, in the United States and other jurisdictions. We also intend to supplement internal innovation through in-licensing of new technologies and compositions of matter as appropriate. We intend to take advantage of any available data exclusivity, market exclusivity, patent term adjustment and patent term extensions.
We routinely monitor the status of existing and emerging intellectual property disclosed by third parties that may impact our business, and to the extent we identify any such disclosures, by evaluating them and taking appropriate courses of action.
As of December 31, 2022, our patent portfolio consists of 71 active patent families. Of these, 29 families relate to our key product candidates (zanidatamab and zanidatamab zovodotin), our preclinical product candidates (including our lead preclinical product candidates ZW191 and ZW171), and our therapeutic platform technology. The remaining 42 patent families relate to other earlier stage potential product candidates or platforms that we do not consider material to our business at this time. One of our patent families is exclusively licensed from a third party. Two of our patent families are co-owned with VAR2 Pharmaceuticals ApS, and one patent family is co-owned with the Provincial Health Services Authority and University of Victoria Industry Partnerships. None of the licensed or co-owned patent families relate to our lead product candidates, zanidatamab and zanidatamab zovodotin. As of December 31, 2022, we have 197 issued patents, 52 of which are U.S. patents.
Therapeutic Antibody Portfolio
Our therapeutic antibody patent portfolio is directed to specific compositions of matter and methods of treatment for our product candidates, including target-specific interactions and immunomodulatory mechanisms. We own the zanidatamab and zanidatamab zovodotin patent portfolio.
• Zanidatamab: Zanidatamab is covered by five patent families. The first is an international patent application filed under the Patent Cooperation Treaty (“PCT”) that is in the national phase with applications pending or issued in Australia, Brazil, Canada, China, Europe, Hong Kong, India, Japan, Korea, Mexico, Russia and the United States.

The fourth PCT application was filed on September 2, 2022, and relates to compositions of matter and methods of making Fc constructs that lack FcgR-binding.
•ProTECT: A PCT application covering the ProTECT platform technology was filed on July 20, 2021. This application covers the composition of matter of polypeptide constructs comprising immunomodulatory ligands and their cognate receptors derived from the immunoglobulin superfamily (such as PDL1 and PD1) fused to antibody variable heavy and light chain region termini respectively via protease-cleavable linkers.
•Computational Chemistry: We own a portfolio of 15 families of computational chemistry patents and patent applications that relate to the computational and algorithmic advances incorporated into the ZymeCAD suite of applications, including advances in general molecular modeling, conformational dynamics, docking, distal mutations, and molecular packing, as well as parallelization and graphical data analysis. Twelve of these patents have issued in the United States. Any patents that issue from these families are expected to expire between 2027 and 2042, absent any adjustments or extensions.
Technology Licensing and In-Licensed Intellectual Property
We identify and, from time to time, selectively enter into technology licensing agreements and intellectual property in-licensing agreements to support pipeline advancement. For example, in March 2016, we entered into an assignment agreement with CDRD Ventures Inc. (“CVI”), as part of our acquisition of Kairos Therapeutics Inc. (“Kairos”), pursuant to which all of CVI’s interests in Kairos’ patents and intellectual property were assigned to us. Under the assignment agreement, we may be required to make future payments of up to an aggregate of C$8.5 million, consisting of (i) a C$2.5 million payment when the first patient is dosed in the first Phase 2 trial and (ii) a C$6.0 million payment when the first patient is dosed in the first Phase 3 trial, to CVI for zanidatamab zovodotin or other product candidates upon the direct achievement of certain clinical development milestones for products incorporating certain Kairos intellectual property. In addition, CVI is eligible to receive low single-digit royalty payments from us on the net sales of such products, pending receipt of regulatory approval. Royalties are payable on a product-by-product and country-by-country basis until the expiration, revocation, invalidation or abandonment of the last valid claim within the patents covering such products in the country of sale. For out-licensed products and technologies incorporating certain Kairos intellectual property, we also may be required to pay CVI a mid-single-digit percentage of certain future revenue.
Manufacturing
We rely on third-party contract manufacturing organizations to provide manufacturing, linker-toxin conjugation, and fill-finish services in order to generate all of the therapeutic antibody supply required for our clinical studies and other research and development activities. To retain focus on our expertise in developing new product candidates, we do not currently plan to develop or operate in-house manufacturing capacity. Our bispecific therapeutic antibody candidates require standard chemistry, manufacturing and control (“CMC”) processes typical of those required for monoclonal antibody manufacturing. We therefore expect to continue to be able to develop product candidates that can be manufactured in a cost-effective fashion by our network of qualified third-party contract manufacturing organizations.
Through our contract manufacturing organizations, we currently have sufficient supply of our product candidates to carry out ongoing and planned preclinical studies. For zanidatamab, we also have sufficient current good manufacturing practices (“cGMP”)-grade supply, together with planned additional manufacturing runs, to complete our ongoing clinical trials. For zanidatamab zovodotin, we have sufficient cGMP-grade supply, together with planned additional manufacturing runs, to complete our ongoing clinical trial and anticipated clinical trials.
Competition
The biopharmaceutical industry is characterized by rapidly advancing technologies, intense competition and a strong emphasis on proprietary products. While we believe that our technology, knowledge, experience and scientific resources provide us with competitive advantages, we face potential competition from many different sources, including major pharmaceutical, specialty pharmaceutical and biotechnology companies, academic institutions and governmental agencies, and public and private research institutions. Any product candidates that we successfully develop and commercialize will compete with existing therapies and new therapies that may become available in the future.
With respect to target discovery activities, competitors and other third parties, including academic and clinical researchers, may be able to access rare families and identify targets before we do.
Many of the companies against which we compete or against which we may compete in the future have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products than we do. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaboration arrangements with large and established companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites, recruiting patients for clinical trials, and by acquiring technologies complementary to, or necessary for, our programs.
The key competitive factors affecting the success of all of our product candidates, if approved, are likely to be their efficacy, safety, convenience and price, the effectiveness of alternative products, the level of competition and the availability of coverage, and adequate reimbursement from government and other third-party payors.
Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products or therapies that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than any products that we may develop. Our competitors also may obtain FDA, European Medicines Agency (“EMA”) or other regulatory approval for their products more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position before we are able to enter the market. In addition, our ability to compete may be affected in many cases by insurers or other third-party payors seeking to encourage the use of generic or biosimilar products.
Zanidatamab and zanidatamab zovodotin are being developed for patients with solid tumors that express HER2, including patients with tumors expressing low levels of HER2. Competing approved HER2-targeted therapies include F. Hoffmann-La Roche Ltd.’s Herceptin, Perjeta, Phesgo, and Kadcyla as well as Novartis Pharmaceuticals Corporation’s Tykerb, Puma Biotechnology, Inc.’s Nerlynx, AstraZeneca PLC / Daiichi Sankyo’s Enhertu, Seagen Inc.’s Tukysa, MacroGenics, Inc.’s Margenza, and various trastuzumab biosimilars.
The FDA and corresponding regulatory authorities will ultimately review our clinical results and determine whether our product candidates are effective. No regulatory agency has made any such determination that any of our product candidates are effective for use by the general public for any indication.
Government Regulation
Government authorities in the United States, at the federal, state and local level, and in other countries extensively regulate, among other things, the research, development, testing, manufacturing, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, post-approval monitoring and reporting, marketing and export and import of products such as those we are developing. Our ADC product candidates are comprised of both a drug product and a biologic product, and will therefore be subject to regulation in the United States as combination products. If marketed individually, each component would be subject to different regulatory pathways and would require approval of independent marketing applications by the FDA. A combination product, however, is assigned to an FDA center that will have primary jurisdiction over its regulation based on a determination of the combination product’s primary mode of action, which is the single mode of action that provides the most important therapeutic action. In the case of our ADCs, we believe that the primary mode of action is attributable to the biologic component of the product. Thus, our product candidates are regulated as therapeutic biologics, with the FDA’s Center for Drug Evaluation and Research having primary jurisdiction over premarket development.
Biological products are subject to regulation under the Federal Food, Drug, and Cosmetic Act, the Public Health Service Act, and other federal, state, local and foreign statutes and regulations. Our product candidates must be approved by the FDA before they may be legally marketed in the United States and by the appropriate foreign regulatory agency before they may be legally marketed in foreign countries.
U.S. Biological Products Development Process
The process required by the FDA before a biologic may be marketed in the United States generally involves the following:
•completion of extensive nonclinical, sometimes referred to as preclinical, laboratory tests and preclinical animal trials and applicable requirements for the humane use of laboratory animals and formulation studies in accordance with applicable regulations, including good laboratory practices (“GLP”);
•submission to the FDA of an IND application, which must become effective before human clinical trials may begin;
•performance of adequate and well-controlled human clinical trials according to the FDA’s regulations commonly referred to as current good clinical practice (“cGCP”) regulations and any additional requirements for the protection of human research subjects and their health information, to establish the safety and efficacy of the proposed biological product for its intended use. The FDA may also impose clinical holds on a biological product candidate at any time before or during clinical trials due to safety concerns or noncompliance. If the FDA imposes a clinical hold, trials may not recommence without FDA authorization and then only under terms authorized by the FDA.
•submission to the FDA of a Biologics License Application (“BLA”) for marketing approval that includes substantive evidence of safety, purity, and potency from results of nonclinical testing and clinical trials;
•satisfactory completion of an FDA inspection of the manufacturing facility or facilities where the biological product is produced to assess compliance with cGMP requirements to assure that the facilities, methods and controls are adequate to preserve the biological product’s identity, strength, quality and purity;
•potential FDA audit of the nonclinical and clinical study sites that generated the data in support of the BLA; and
•FDA review and approval, or licensure, of the BLA.
Human clinical trials are typically conducted in sequential phases that may overlap or be combined:
•Phase 1. The biological product candidate is initially introduced into healthy human volunteers and tested for safety. In the case of some products for severe or life-threatening diseases, especially when the product may be too inherently toxic to ethically administer to healthy volunteers, the initial human testing is often conducted in patients.
•Phase 2. The biological product candidate is evaluated in a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate the efficacy of the product for specific targeted diseases and to determine dosage tolerance, optimal dosage and dosing schedule.
•Phase 3. Clinical trials are undertaken to further evaluate dosage, clinical efficacy, potency, and safety in an expanded patient population at geographically dispersed clinical study sites. These clinical trials are intended to establish the overall risk/benefit ratio of the product and provide an adequate basis for product labelling.
During all phases of clinical development, regulatory agencies require extensive reporting, monitoring and auditing of all clinical activities, clinical data, and clinical study investigators.
A sponsor, an institutional review board (“IRB”) or independent ethics committee, the FDA or other regulatory or monitoring authorities may suspend a clinical study at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk, failure to conduct the clinical trial in accordance with regulatory requirements or clinical protocols, failure to demonstrate a benefit from using the investigational drug, changes in government regulations or administrative actions.
Sponsors of clinical trials of FDA-regulated products, including biologics, are required to register and disclose certain clinical trial information, which is publicly available at www.clinicaltrials.gov. Information related to the product, patient population, phase of investigation, study sites and investigators, and other aspects of the clinical trial is then made public as part of the registration. Sponsors are also obligated to discuss the results of their clinical trials after completion. Disclosure of the results of these trials can be delayed until the new product or new indication being studied has been approved.
U.S. Review and Approval Processes
After the completion of clinical trials of a biological product candidate, FDA approval of a BLA must be obtained before commercial marketing of the biological product. When a BLA is submitted, the FDA conducts a preliminary review to determine whether the application is sufficiently complete to be accepted for filing. If it is not, the FDA may refuse to file the application and request additional information, in which case the application must be resubmitted with the supplemental information, and review of the application is delayed. Upon accepting the BLA for filing, the FDA will conduct an in-depth review the BLA and may hold a public hearing where an independent advisory committee of expert advisors considers key questions regarding the product candidate. This advisory committee makes a recommendation to the FDA, which is not binding on the FDA, but is generally followed.
The FDA is authorized to designate certain products for expedited review if they are intended to address an unmet medical need in the treatment of a serious or life-threatening disease or condition. In particular, the FDA may designate a product for Fast Track review if it is intended, whether alone or in combination with one or more other drugs, for the treatment of a serious or life-threatening disease or condition, and it demonstrates the potential to address unmet medical needs for such a disease or condition. For Fast Track designated products, sponsors may have a higher number of interactions with the FDA and the FDA may initiate review of sections of a Fast Track product’s New Drug Application or BLA before the application is complete. The FDA has granted two Fast Track designations to zanidatamab for the first-line treatment of patients with HER2-overexpressing GEA in combination with standard of care chemotherapy and for previously treated or recurrent gene-amplified BTC.
The FDA also may designate a product as a Breakthrough Therapy if it is intended, alone or in combination with one or more other products, to treat a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the product may demonstrate substantial improvement over existing therapies on one or more clinically important endpoints, such as substantial treatment effects observed early in clinical development. For products that have been designated as a Breakthrough Therapy, interaction and communication between the FDA and the sponsor of the trial can help to identify the most efficient path for clinical development while minimizing the number of patients placed in ineffective control regimens. Products designated as a Breakthrough Therapy by the FDA can also be eligible for accelerated approval. The FDA has granted Breakthrough Therapy designation for zanidatamab in HER2 gene-amplified BTC patients who have received prior systemic chemotherapy. In December 2022, the Consolidated Appropriations Act, 2023, including the Food and Drug Omnibus Reform Act (“FDORA”), was signed into law. FDORA made several changes to the FDA’s authorities and its regulatory framework, including, among other changes, reforms to the accelerated approval pathway, such as requiring the FDA to specify conditions for post-approval study requirements and setting forth procedures for the FDA to withdraw a product on an expedited basis for non-compliance with post-approval requirements.
Under the Pediatric Research Equity Act, certain applications for approval must include an assessment, generally based on clinical study data, of the safety and effectiveness of the subject drug in relevant pediatric populations. The FDA may waive or defer the requirement for a pediatric assessment, either at the company’s request or by the FDA’s initiative. The FDA may determine that a Risk Evaluation and Mitigation Strategy (“REMS”) is necessary to ensure that the benefits of a new product outweigh its risks. A REMS may include various elements, ranging from a medication guide or patient package insert to limitations on who may prescribe or dispense the drug or other elements to assure safe use, depending on what the FDA considers necessary for the safe use of the drug.
Before approving a BLA, the FDA will inspect the facilities at which the product is manufactured. The FDA will not approve the product unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving a BLA, the FDA will typically inspect one or more clinical sites to assure that the clinical trials were conducted in compliance with IND study requirements and cGCP requirements.
Notwithstanding the submission of relevant data and information, the FDA may ultimately decide that the BLA does not satisfy its regulatory criteria for approval and deny approval. Data obtained from clinical trials are not always conclusive and the FDA may interpret data differently than the applicant interprets the same data. If the FDA decides not to approve the BLA in its present form, the FDA will issue a complete response letter that usually describes all of the specific deficiencies in the BLA identified by the FDA. The deficiencies identified may be minor (for example, requiring labeling changes) or major (for example, requiring additional clinical trials). Additionally, the complete response letter may include recommended actions that the applicant might take to place the application in a condition for approval. If a complete response letter is issued, the applicant may either resubmit the BLA, addressing all of the deficiencies identified in the letter, or withdraw the application.
If a product receives regulatory approval, the approval may be significantly limited to specific diseases and dosages or the indications for use may otherwise be limited, which could restrict the commercial value of the product. Further, the FDA may require that certain contraindications, warnings or precautions be included in the product labeling. The FDA may impose restrictions and conditions on product distribution, prescribing, or dispensing in the form of a REMS, or otherwise limit the scope of any approval. In addition, the FDA may require post-marketing clinical trials, sometimes referred to as Phase 4 clinical trials, designed to further assess a biological product’s safety and effectiveness, and testing and surveillance programs to monitor the safety of approved products that have been commercialized.
Orphan Drug Designation
The Orphan Drug Act established incentives for the development of drugs intended to treat rare diseases or conditions, which generally are diseases or conditions affecting less than 200,000 individuals in the United States at the time of the request for orphan designation. If a sponsor demonstrates that a drug is intended to treat a rare disease or condition and meets other applicable requirements, the FDA grants Orphan Drug Designation to the product for that use. The FDA has granted zanidatamab Orphan Drug Designation for the treatment of BTC and GEA.
The benefits of Orphan Drug Designation include tax credits for clinical testing expenses and exemption from user fees. A drug candidate that is approved for the orphan drug designated use typically is granted seven years of orphan drug exclusivity. During that period, the FDA generally may not approve any other application for the same product for the same indication, although there are exceptions, most notably when the later product is shown to be clinically superior to the product with exclusivity. However, the FDA Reauthorization Act, which was enacted in 2017, requires, among other things, that certain orphan drugs for cancer be tested for children. The government has also increased focus on the potential misuse of the orphan drug approval process to increase the price of orphan drugs.
In Catalyst Pharms., Inc. v. Becerra, 14 F.4th 1299 (11th Cir. 2021), the court disagreed with the FDA’s longstanding position that the orphan drug exclusivity only applies to the approved use or indication within an eligible disease, and not to all uses or indications within the entire disease or condition. In particular, the circuit court held that the orphan drug exclusivity for Catalyst’s drug blocked the FDA’s approval of another drug for all uses or indications within the same orphan-designated disease, Lambert-Eaton myasthenic syndrome (LEMS), even though Catalyst’s drug was approved at that time only for use in the treatment of LEMS in adults. Accordingly, the court ordered the FDA to set aside the approval of a drug indicated for LEMS in children. This decision created uncertainty in the application of the orphan drug exclusivity. On January 24, 2023, the FDA published a notice in the Federal Register to clarify that while the agency complies with the court’s order in Catalyst, the FDA intends to continue to apply its longstanding interpretation of the regulations to matters outside of the scope of the Catalyst order - that is, the agency will continue tying the scope of orphan drug exclusivity to the uses or indications for which a drug is approved, which permits other sponsors to obtain approval of a drug for new uses or indications within the same orphan designated disease or condition that have not yet been approved. It is unclear how future litigation, legislation, agency decisions, and administrative actions will impact the scope of the orphan drug exclusivity.
Post-Approval Requirements
Even if regulatory approval is granted, a marketed product is subject to continuing comprehensive requirements under federal, state and foreign laws and regulations, including requirements and restrictions regarding adverse event reporting,
recordkeeping, marketing, and compliance with cGMP. Adverse events reported after approval of a drug can result in additional restrictions on the use of a marketed product or requirements for additional post-marketing studies or clinical trials.
Maintaining substantial compliance with applicable federal, state and local statutes and regulations requires the expenditure of substantial time and financial resources. Rigorous and extensive FDA regulation of biological products continues after approval, particularly with respect to cGMP requirements. Biological product manufacturers and other entities involved in the manufacture and distribution of approved biological products are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP requirements and other laws. We will rely, and expect to continue to rely, on third parties for the production of clinical and commercial quantities of any products that we may commercialize. Manufacturers of our products are required to comply with applicable requirements in the cGMP regulations, including quality control and quality assurance and maintenance of records and documentation. Other post-approval requirements applicable to biological products include record-keeping requirements, reporting of adverse effects and reporting updated safety and efficacy information. Discovery of previously unknown problems or the failure to comply with the applicable regulatory requirements relating to the manufacture or promotion of an approved product may result in restrictions on the marketing of a product or withdrawal of the product from the market as well as significant administrative, civil or criminal sanctions.
Biosimilars and Exclusivity
The 2010 Patient Protection and Affordable Care Act (“PPACA”) includes a subtitle called the Biologics Price Competition and Innovation Act of 2009 (“BPCIA”), which created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an FDA-licensed reference biological product.
Under the BPCIA, the approval of a biosimilar product may not be made effective by the FDA until 12 years from the date on which the reference product was first licensed. During this 12-year period of exclusivity, another company may still market a competing version of the reference product if the FDA approves a full BLA for the competing product containing the sponsor’s own preclinical data and data from adequate and well-controlled clinical trials to demonstrate the safety, purity and potency of their product. The BPCIA also created certain exclusivity periods for biosimilars approved as the first interchangeable for biologic products.
Canadian Review and Approval Process
In Canada, our biologic product candidates and our research and development activities are primarily regulated by the Food and Drugs Act and the rules and regulations thereunder, which are enforced by Health Canada. Health Canada regulates, among other things, the research, development, testing, manufacture, packaging, storage, recordkeeping, labeling, advertising, promotion, distribution, post-approval monitoring, marketing and import and export of pharmaceutical products. Drug approval laws require licensing of manufacturing facilities, carefully controlled research and testing of products, and government review and approval of experimental results prior to giving approval to sell drug products, including biologic drug products. Regulators also typically require that rigorous and specific standards such as cGMP, GLP and cGCP are followed in the manufacture, testing and clinical development, respectively, of any drug product. The processes for obtaining regulatory approvals in Canada, along with subsequent compliance with applicable statutes and regulations, require the expenditure of substantial time and financial resources.
The principal steps required for drug approval in Canada are as follows:
Preclinical Toxicology Studies and Clinical Trials
Non-clinical studies are conducted in vitro and in animals to evaluate pharmacokinetics, metabolism and possible toxic effects to provide evidence of the safety of the drug candidate prior to its administration to humans in clinical studies and throughout development. Such studies are conducted in accordance with applicable laws and GLP.
In Canada, the process of conducting clinical trials with a new drug cannot begin until a Clinical Trial Application (“CTA”) is submitted and the required number of days has lapsed without objection from Health Canada. Biological drugs carry additional risks, as compared to traditional small-molecule drugs, associated with complexity and variability in manufacturing that can contribute to increased lot-to-lot variation of the final product, and with the potential for adventitious agents. Therefore, the content requirements for the quality information for biological drugs to be used in clinical trials are different from those for standard small-molecule pharmaceutical drugs (for example, the inclusion of information on manufacturing facilities is required
for biological drugs). In addition, it is necessary to have more stringent controls on the release of biologic drug lots used in authorized clinical trials.
Similar regulations apply in Canada regarding clinical trials as in the United States. In Canada, Research Ethics Boards (“REBs”), instead of IRBs, are used to review and approve clinical trial plans. Human clinical trials are typically conducted in three sequential phases, as discussed above in the context of government regulation in the United States.
The manufacture of investigational drugs for the conduct of human clinical trials is subject to cGMP requirements. Investigational drugs and active pharmaceutical ingredients imported into Canada are also subject to regulation by Health Canada relating to their labeling and distribution. Progress reports detailing the results of the clinical trials must generally be submitted at least annually to Health Canada and/or the applicable REBs, and more frequently if serious adverse events occur.
New Drug Submission
Upon successful completion of Phase 3 clinical trials, the company sponsoring a new drug then assembles all the preclinical and clinical data and other testing relating to the product’s pharmacology, chemistry, manufacture, and controls, and submits it to Health Canada as part of a New Drug Submission (“NDS”). The NDS is then reviewed by Health Canada for approval to market the drug.
The testing and approval process for an NDS requires substantial time, effort and financial resources, and may take several years to complete. Biologic drugs, such as our candidates, differ from standard small-molecule drugs in that applicants must include more detailed chemistry and manufacturing information. This is necessary to help ensure the purity and quality of the product, for example to help ensure that it is not contaminated by an undesired microorganism. Data obtained from preclinical and clinical testing are not always conclusive and may be susceptible to varying interpretations, which could delay, limit or prevent regulatory approval. Health Canada may not grant approval of an NDS on a timely basis, or at all.
Even if Health Canada approves a product candidate, it may limit the approved indications for use of the product candidate, require that contraindications, warnings or precautions be included in the product labeling, require that post-approval studies be conducted to further assess a drug’s safety after approval, require testing and surveillance programs to monitor the product after commercialization, or impose other conditions, including distribution restrictions or other risk management mechanisms.
Biologic products in particular are monitored post-approval by being placed on a lot-release schedule tailored to their potential risk, manufacturing, testing and inspection history to date. With higher-risk biologics, each lot is tested before being released for sale in Canada. Moderate-risk biologics are periodically tested at the discretion of Health Canada while manufacturers of low-risk biologics usually only need to contact Health Canada regarding lots being sold or for providing certification of complete and satisfactory testing. Products are carefully scrutinized before they are placed in any level of the lot-release process, and the testing regime for a biologic may be altered at any time. On December 17, 2022, the Minister of Health in Canada published proposed amendments to the Food and Drug Regulations, and several of the amendments relate to biologic drugs. The purpose of the amendments is to modernize the biologics regulatory regime by repealing outdated requirements and replacing them with those that reflect current safety practices. Proposed amendments include enabling Health Canada to require certain labelling statements for safety reasons on a case-by-case basis, and clarifying the Minister’s authority to consider information or material obtained during on-site evaluations. Other proposed amendments include clarifying the record retention expectations for market authorization holders, and providing a general framework to minimize the potential for contamination of drugs, active ingredients and biological source material between processes. The proposed amendments are still in draft form.
Health Canada may prevent or limit further marketing of a product based on the results of post-marketing studies or surveillance programs. After approval, some types of changes to the approved product, such as adding new indications, manufacturing changes, and additional labeling claims, are subject to further testing requirements, notification, and regulatory authority review and approval. Further, should new safety information arise, additional testing, product labeling or regulatory notification may be required.
Canadian Biosimilars and Exclusivity
The term biosimilar is used by Health Canada to describe a biologic drug that enters the market subsequent to a version previously authorized in Canada and with demonstrated similarity to a reference biologic drug. Accordingly, a biosimilar (previously known in Canada as a subsequent entry biologic or SEB) will in all instances be a subsequent entrant onto the Canadian market.
Based on Health Canada guidance documents, a biosimilar can rely in part on prior information regarding safety and efficacy that is deemed relevant due to the demonstration of similarity to the reference biologic drug and which influences the amount and type of original data required. Generic drugs are chemically derived products that are pharmaceutically equivalent to innovative drugs, whereas biosimilars are products of a biologic nature that are similar to innovative biologics. According to Health Canada, it is not currently possible to demonstrate that two biologic drugs are pharmaceutically equivalent, and therefore the regulatory approval process for generics and biosimilars is different: biosimilars are approved using the standard NDS pathway with some allowances made for reduced safety and efficacy information set out in guidance documents, while generic drugs are approved using an abbreviated new drug submission pathway set out in guidance and law. In part because it continues to be set out only in guidance and not law, the pathway for receiving biosimilar approval is somewhat in flux and subject to some uncertainty.
As discussed above, all biosimilars enter the market subsequent to a biologic drug product previously approved in Canada and to which the biosimilar is considered similar. As such, biosimilars are subject to existing laws and regulations outlined in the Patented Medicines (Notice of Compliance) Regulations and the Food and Drug Regulations, and related guidance documents.
Similar to the Hatch-Waxman Amendments in the United States, Canada has the Patented Medicines (Notice of Compliance) Regulations, which require a company that files a drug submission that references a patented product to address any relevant patents listed on the Patent Register prior to being able to receive approval from Health Canada. The Canadian regime is similar to the U.S. regime, but a number of distinctions do exist.
Like the United States, Canada also has data protection in addition to patent protection, but again differences exist between the two jurisdictions. For example, Canada’s data protection applies to “innovative drugs” (i.e., a drug that contains a medicinal ingredient not previously approved in a drug by the Minister of Health and that is not a variation of a previously approved medicinal ingredient such as a salt, ester, enantiomer, solvate or polymorph) and, where it exists, lasts for eight years in most (but not all) circumstances. In general biologics can be considered innovative drugs but biosimilars are not.
Additional Regulation
In addition to the foregoing, provincial, state and federal U.S. and Canadian laws regarding environmental protection and hazardous substances affect our business. These and other laws govern our use, handling and disposal of various biological, chemical and radioactive substances used in, and wastes generated by, our operations. If our operations result in contamination of the environment or expose individuals to hazardous substances, we could be liable for damages and governmental fines. We believe that we are in material compliance with applicable environmental laws and that continued compliance therewith will not have a material adverse effect on our business. We cannot predict, however, how changes in these laws may affect our future operations.
Government Regulation Outside of the United States and Canada
In addition to regulations in the United States, we will be subject to a variety of regulations in other jurisdictions governing, among other things, clinical studies and any commercial sales and distribution of our products.
Whether or not we obtain FDA approval for a product, we must obtain the requisite approvals from regulatory authorities in foreign countries prior to the commencement of clinical studies or marketing of the product in those countries. Certain countries outside of the United States have a similar process that requires the submission of a clinical study application much like the IND prior to the commencement of human clinical studies. In the EU, for example, a CTA must be submitted to each country’s national health authority and an independent ethics committee, much like the FDA and the IRB, respectively. Once the CTA is approved in accordance with a country’s requirements, clinical study development may proceed.
The requirements and process governing the conduct of clinical studies, product licensing, coverage, pricing and reimbursement vary from country to country. In all cases, the clinical studies are conducted in accordance with cGCP and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki.
Pharmaceutical Coverage, Pricing and Reimbursement
Significant uncertainty exists as to the coverage and reimbursement status of any product candidates for which we may obtain regulatory approval. In the United States and markets in other countries, sales of any products for which we receive regulatory approval for commercial sale will depend, in part, on pricing and the availability of coverage and adequate reimbursement from
third-party payors. These third-party payors may deny coverage or reimbursement for a product or therapy in whole or in part if they determine that the product or therapy was not medically appropriate or necessary. Third-party payors may attempt to control costs by limiting coverage to specific drug products on an approved list, or formulary, which might not include all of the FDA-approved drug products for a particular indication, requiring pre-approval of coverage for new or innovative drug therapies before they will reimburse healthcare providers who use such therapies, and by limiting the amount of reimbursement for particular procedures or drug treatments. Additionally, coverage and reimbursement for drug products can differ significantly from payor to payor. The Medicare and Medicaid programs are often used as models by private payors and other governmental payors to develop their coverage and reimbursement policies for drugs and biologics. However, one third-party payor’s decision to cover a particular drug product does not ensure that other payors will also provide coverage for the product, or will provide coverage at an adequate reimbursement rate.
The cost of pharmaceuticals continues to generate substantial governmental and third-party payor interest. We expect that the pharmaceutical industry will experience pricing pressures due to the trend toward managed healthcare, the increasing influence of managed care organizations and additional legislative proposals. Third-party payors are increasingly challenging the price and examining the medical necessity and cost-effectiveness of medical products and services, in addition to their safety and efficacy. We may need to conduct expensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of our products to obtain third-party payor coverage, in addition to the costs required to obtain the FDA approvals. Our product candidates may not be considered medically necessary or cost effective. A payor’s decision to provide coverage for a drug product does not imply that an adequate reimbursement rate will be approved. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize an appropriate return on our investment in product development.
While we cannot predict whether any proposed cost-containment measures will be adopted or otherwise implemented in the future, these requirements or any announcement or adoption of such proposals could have a material adverse effect on our ability to obtain adequate prices for our product candidates and to operate profitably.
In international markets, pricing, reimbursement and healthcare payment systems vary significantly by country, and many countries have instituted price ceilings on specific products and therapies. There can be no assurance that our products will be considered medically reasonable and necessary for a specific indication, that our products will be considered cost effective by third-party payors, that coverage or an adequate level of reimbursement will be available or that third-party payors’ reimbursement policies will not adversely affect our ability to sell our products profitably.
Healthcare Reform
The United States and some other jurisdictions are considering or have enacted a number of legislative and regulatory proposals to change the healthcare system in ways that could affect our ability to sell our future products profitably. Among policy makers and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality or expanding access. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives. For example, in August 2022, Congress passed the Inflation Reduction Act of 2022, which includes prescription drug provisions that have significant implications for the pharmaceutical industry and Medicare beneficiaries, including allowing the federal government to negotiate a maximum fair price for certain high-priced single-source Medicare drugs, imposing penalties and excise tax for manufacturers that fail to comply with the drug price negotiation requirements, requiring inflation rebates for all Medicare Part B and Part D drugs, with limited exceptions, if their drug prices increase faster than inflation, and redesigning Medicare Part D to reduce out-of-pocket prescription drug costs for beneficiaries, among other changes. The impact of these legislative, executive, and administrative actions and any future healthcare measures and agency rules implemented by the Biden administration on us and the pharmaceutical industry as a whole is unclear.
We expect that the PPACA, as well as reform measures that may be adopted in the future, may result in more rigorous coverage criteria and lower reimbursement, and in additional downward pressure on the price that we receive for any approved product. Any reduction in reimbursement from Medicare or other government-funded programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability or commercialize our drugs, once regulatory approval is obtained.
Other Healthcare Laws and Compliance Requirements
In the United States, the research, manufacturing, distribution, sale and promotion of drug products are subject to regulation by various federal, state and local authorities in addition to the FDA, including the Centers for Medicare & Medicaid Services, other divisions of the U.S. Department of Health and Human Services (e.g., the Office of Inspector General), the U.S. Department of Justice, state attorneys general, and other state and local government agencies.
If our operations are found to be in violation of any of the U.S. federal and state laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including criminal and significant civil monetary penalties, damages, fines, disgorgement, imprisonment, exclusion from participation in government healthcare programs, injunctions, recall or seizure of products, total or partial suspension of production, denial or withdrawal of pre-marketing product approvals, private qui tam actions brought by individual whistleblowers in the name of the government or refusal to allow us to enter into supply contracts, including government contracts, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations. We may also be subject to additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement with a governmental entity to resolve allegations that we have violated these laws. To the extent that any of our product candidates, once approved, are sold in a foreign country, we may be subject to similar foreign laws and regulations, which may include, for instance, applicable post-approval requirements, including safety surveillance, anti-fraud and abuse laws, and implementation of corporate compliance programs and reporting of payments or transfers of value to healthcare professionals.
Sales and Marketing
As a clinical-stage biopharmaceutical company, we do not currently possess the commercial infrastructure required to launch and market our product candidates. For zanidatamab and zanidatamab zovodotin, we have entered into development and commercialization agreements with BeiGene whereby BeiGene is responsible for certain clinical development activities and all commercial activities in Asia (excluding Japan but including the People’s Republic of China, South Korea and other countries), Australia and New Zealand. For zanidatamab, under the Jazz Collaboration Agreement, Jazz is responsible for all development and commercial activities globally outside of the BeiGene territories, at Jazz’s cost and expense. To date, we have not entered into any other agreements granting commercialization rights to zanidatamab, zanidatamab zovodotin or any of our other product candidates. To access the sales, marketing and distribution capacity required to market our drug candidates, we plan to selectively establish additional partnerships with biotechnology and pharmaceutical companies having established commercial capabilities in relevant indications. The timing and nature of such agreements will be determined by market size and complexity, access to pre-commercial and commercial infrastructure and our resource availability for developing a commercial organization. For product candidates targeting patient populations that can be serviced by a small, specialized commercial effort, we may seek out co-development and co-promotion agreements granting commercialization rights to an established commercial partner in some jurisdictions while allowing us to build these capabilities in other jurisdictions.
Human Capital Resources
As of December 31, 2022, we had 294 employees, including 291 full-time employees, 196 of whom were primarily engaged in research and development activities and 68 of whom hold an M.D. or Ph.D. degree. 168 of our full-time employees were based in Canada and 123 in the United States. As part of our renewed focus on achieving our key strategic priorities, in January 2022, we announced our intention to restructure our workforce with a target of reducing our employee headcount by at least 25% across the organization by the end of 2022. As of March 31, 2022, we had exceeded that 25% target.
We consider our employees to be an essential driver of our business and key to our future prospects and believe that our relationship with our employees is good. We monitor our compensation programs closely and provide what we consider to be a competitive mix of compensation and benefits for all our employees, including participation in our equity programs. None of our employees are represented by a labor organization or covered by a collective bargaining arrangement.
Corporate History
Effective October 13, 2022, we became a Delaware corporation, following receipt of necessary shareholder, stock exchange, and court approvals (the “Redomicile Transactions”). Zymeworks Inc. was incorporated under the laws of the State of Delaware in June 2022. Our principal executive offices are located at 108 Patriot Drive, Suite A, Middletown, Delaware 19709, and our telephone number is (302) 274-8744. Our predecessor, now named Zymeworks BC Inc., was originally incorporated on September 8, 2003 under the Canada Business Corporations Act under the name “Zymeworks Inc.” On October 22, 2003, our
predecessor was registered as an extra-provincial company under the Company Act (British Columbia), the predecessor to the Business Corporations Act (British Columbia) (“BCBCA”). Our predecessor continued to British Columbia under the BCBCA on May 2, 2017.

Our Risk Factors are not guarantees that no such conditions exist as of the date of this report and should not be interpreted as an affirmative statement that such risks or conditions have not materialized, in whole or in part.
Summary of Risk Factors
Below is a summary of the principal factors that make an investment in our common stock speculative or risky. This summary does not address all of the risks that we face. Additional discussion of the risks summarized in this risk factor summary, and other risks that we face, can be found below under the heading “Risk Factors” and should be carefully considered, together with other information in this Form 10-K and our other filings with the SEC, before making an investment decision regarding our common stock.
•We have a limited number of product candidates, all which are still in preclinical or clinical development. If we do not obtain regulatory approval of one or more of our product candidates, or experience significant delays in doing so, our business will be materially adversely affected.
•Clinical trials are expensive, time consuming, difficult to design and implement, and involve uncertain outcomes. Furthermore, the results of previous preclinical studies and clinical trials may not be predictive of future results, and the results of our current and planned clinical trials may not satisfy the requirements of the FDA or comparable regulatory authorities outside the United States.
•Our long-term prospects depend in part upon discovering, developing and commercializing additional product candidates, which may fail in development or suffer delays that adversely affect their commercial viability.
•Our product candidates may have undesirable side effects that may delay or prevent marketing approval or, if approval is received, require them to be taken off the market, require them to include safety warnings or otherwise limit their sales; no regulatory agency has made any determination that any of our product candidates are safe or effective for use by the general public for any indication.
•We face significant competition, and if our competitors develop and market products that are more effective, safer or less expensive than our product candidates, our commercial opportunities will be negatively impacted.
•If any of our product candidates receive regulatory approval, the approved products may not achieve broad market acceptance among physicians, patients, the medical community and third-party payors, in which case revenue generated from their sales would be limited.
•We may not be successful in our efforts to use our therapeutic platforms to build a pipeline of product candidates.
•If any product liability lawsuits are successfully brought against us or any of our strategic partners, we may incur substantial liabilities and may be required to limit commercialization of our product candidates.
•Security breaches and incidents, loss of data and other disruptions could compromise sensitive information related to our business or protected health information or prevent us from accessing critical information and expose us to liability, which could adversely affect our business and our reputation.
•Current and future legislation may increase the difficulty and cost for us to commercialize any products that we or our strategic partners develop and affect the prices we may obtain.
•We have incurred significant losses since inception and anticipate that we will continue to incur losses for the foreseeable future. We have no products approved for commercial sale, and to date we have not generated any revenue or profit from product sales. We may never achieve or sustain profitability.
•We will require substantial additional funding, which may not be available to us on acceptable terms, or at all, and, if not available, may require us to delay, scale back, or cease our product development programs or operations.
•We will depend on our collaborative relationship with Jazz to further develop and commercialize zanidatamab, and if our relationship is not successful or is terminated, we may be delayed in or unable to effectively develop and/or commercialize zanidatamab, which could have a material adverse effect on our business.
•Our existing strategic partnerships are important to our business, and future strategic partnerships will likely also be important to us. If we are unable to maintain our strategic partnerships, or if these strategic partnerships are not successful, our business could be adversely affected.
•We rely on third-party manufacturers to produce our product candidates and on other third parties to provide supplies and store, monitor and transport bulk drug substance and drug product. We and our third-party partners may encounter difficulties with respect to these activities that could delay or impair our ability to initiate or complete our clinical trials or commercialize approved products.
•We rely on third parties to monitor, support, conduct and oversee clinical trials of the product candidates that we are developing and, in some cases, to maintain regulatory files for those product candidates. We may not be able to obtain regulatory approval for our product candidates or commercialize any products that may result from our development efforts if we are not able to maintain or secure agreements with such third parties on acceptable terms, if these third parties do not perform their services as required, or if these third parties fail to timely transfer any regulatory information held by them to us.
•If we are unable to obtain, maintain and enforce patent and trade secret protection for our product candidates and related technology, our business could be materially harmed.
•If we are unable to protect the confidentiality of our proprietary information, the value of our technology and products could be adversely affected.
•Our effective tax rate may change in the future.
•Our stock price is likely to be volatile and the market price of our common stock may drop below the price paid by stockholders.
•Delaware law and provisions in our amended and restated certificate of incorporation and amended and restated bylaws might delay, discourage or prevent a change in control of Zymeworks or changes in our management, thereby depressing the market price of our common stock.
Risk Factors
Risks Related to Our Business and the Development and Commercialization of Our Product Candidates
We have a limited number of product candidates, all which are still in preclinical or clinical development. If we do not obtain regulatory approval of one or more of our product candidates, or experience significant delays in doing so, our business will be materially adversely affected.
We currently have no products approved for sale or marketing in any country, and may never be able to obtain regulatory approval for any of our product candidates. As a result, we are not currently permitted to market any of our product candidates in the United States or in any other country until we obtain regulatory approval from the FDA or comparable regulatory authorities outside the United States. Our product candidates are in preclinical or clinical development and we have not submitted an application, or received marketing approval, for any of our product candidates. Obtaining regulatory approval of our product candidates will depend on many factors, including:
•completing clinical trials that demonstrate the efficacy and safety of our product candidates;
•preparation and submission to the appropriate regulatory authorities of an application for marketing approval that includes substantial evidence of safety, purity and potency from results of nonclinical testing and clinical trials;
•establishing and maintaining adequate commercial manufacturing arrangements or establishing our own commercial manufacturing capabilities or reliable arrangements with third-party contract manufacturers;
•potential pre-approval audits of nonclinical sites, clinical trial sites, and third-party manufacturing sites that generated the data and product in support of the marketing application; and
•launching commercial sales, marketing and distribution operations.
Many of these factors are wholly or partially beyond our control, including clinical advancement, the regulatory submission process and changes in the competitive landscape. If we do not achieve one or more of these factors in a timely manner, we could experience significant delays or an inability to develop our product candidates at all.
Clinical trials are expensive, time consuming, difficult to design and implement, and involve uncertain outcomes. Furthermore, the results of previous preclinical studies and clinical trials may not be predictive of future results, and the results of our current and planned clinical trials may not satisfy the requirements of the FDA or comparable regulatory authorities outside the United States.
We have not previously submitted a BLA to the FDA or similar marketing applications to foreign health authorities. A BLA must include extensive preclinical and clinical data and supporting information to establish the product candidate’s safety, purity and efficacy for each desired indication. The BLA must also include significant information regarding the manufacturing controls for the product. The novel nature of our product candidates may introduce uncertain, complex, expensive and lengthy challenges that could impact regulatory approval. Even if we eventually complete clinical testing and receive approval of any regulatory filing for our product candidates, the FDA or foreign health authorities may approve our product candidates for a more limited indication or a narrower patient population than we originally requested.
There is typically an extremely high rate of attrition from the failure of product candidates proceeding through preclinical studies and clinical trials. Positive or timely results from preclinical or early-stage trials do not ensure positive or timely results in late-stage clinical trials or product approval by the FDA or comparable regulatory authorities outside the United States. We will be required to demonstrate with substantial evidence through well-controlled clinical trials that our product candidates are safe and effective for use in a diverse population before we can seek regulatory approvals for their commercial sale. Our clinical trials may produce negative or inconclusive results, and we or any of our current and future strategic partners may decide, or regulators may require us, to conduct additional clinical or preclinical testing. In some instances, there can be significant variability in safety or efficacy results between different preclinical studies and clinical trials of the same product candidate due to numerous factors, including changes in clinical trial procedures set forth in protocols, differences in the size and type of the patient populations, changes in and adherence to the clinical trial protocols and the rate of dropout among clinical trial participants. Moreover, success in preclinical studies or early-stage clinical trials does not mean that future clinical trials or registrational clinical trials will be successful because product candidates in later-stage clinical trials may fail to demonstrate sufficient safety and efficacy to the satisfaction of the FDA and comparable regulatory authorities outside the United States, despite having progressed through preclinical studies and initial clinical trials. Product candidates that have shown promising results in early clinical trials may suffer significant setbacks in subsequent clinical trials or registrational clinical trials. For example, a number of companies in the pharmaceutical industry have suffered significant setbacks in late-stage clinical trials, even after obtaining promising results in earlier-stage clinical trials. Similarly, interim results of a clinical trial do not necessarily predict final results.
There is a high failure rate for biopharmaceutical products proceeding through clinical trials. A number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in later stage clinical trials even after achieving promising results in earlier stage clinical trials. Data obtained from preclinical and clinical activities are subject to varying interpretations, which may delay, limit or prevent regulatory approval. In addition, regulatory delays or rejections may be encountered as a result of many factors, including changes in regulatory policy during the period of product development. For example, the FDA’s Oncology Center of Excellence initiated Project Optimus to reform the dose optimization and dose selection paradigm in oncology drug development and Project FrontRunner to help develop and implement strategies to support approvals in the early clinical setting, among other goals. How the FDA plans to implement those goals and their impact on specific clinical programs and the industry are unclear.
Applications for our product candidates could fail to receive regulatory approval for many reasons, including but not limited to the following:
•the FDA or foreign health authorities may disagree with the design, implementation or data analyses of our clinical trials;
•the FDA or foreign health authorities may determine that our product candidate(s) do not have adequate risk-benefit ratio or have undesirable or unintended side effects, toxicities or other characteristics that preclude our obtaining marketing approval or prevent or limit commercial use;
•the population studied in the clinical program may not be sufficiently broad or representative to assure efficacy and safety in the full population for which we seek approval;
•the FDA or foreign health authorities may disagree with our interpretation of data from preclinical studies or clinical trials;
•the data collected from clinical trials of our product candidates may not be sufficient to support the submission of a BLA or other submission or to obtain regulatory approval in the United States or elsewhere;
•the FDA or foreign health authorities may fail to approve the manufacturing processes, test procedures and specifications or facilities of third-party manufacturers with which we contract for clinical and commercial supplies; and
•the approval policies or regulations of the FDA or foreign health authorities may significantly change in a manner rendering our clinical data insufficient for approval.
Additionally, we have conducted, and may in the future conduct, clinical trials outside the United States. Although the FDA may accept data from clinical trials conducted outside the United States, acceptance of these data is subject to certain conditions imposed by the FDA and its determination that the trials also complied with all applicable U.S. laws and regulations. If the FDA does not accept the data from any clinical trials we conduct outside the United States, it would likely result in the need for additional trials, which would be costly and time-consuming and delay or halt our development of any future product candidates.
If clinical trials for our product candidates are prolonged, delayed or stopped, we may be unable to obtain regulatory approval and commercialize our product candidates on a timely basis, or at all, which would require us to incur additional costs and delay our receipt of any product revenue.
We are currently evaluating zanidatamab in Phase 1, Phase 2, and Phase 3 clinical trials, including certain ongoing pivotal clinical trials, and zanidatamab zovodotin in a Phase 1 clinical trial in patients with recurrent or metastatic HER2-expressing solid tumors. We may experience delays in our ongoing or future preclinical studies or clinical trials, and we do not know whether future preclinical studies or clinical trials will begin on time, need to be redesigned, enroll an adequate number of patients on time or be completed on schedule, if at all. Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during clinical development, and, because our product candidates are in an early stage of development, there is a high risk of failure and we may never succeed in developing marketable products. The results of preclinical studies and early clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials, particularly because early trials have smaller numbers of subjects tested. In addition, it is not uncommon for product candidates to exhibit unforeseen safety or efficacy issues, such as immunogenicity, when tested in humans despite promising results in preclinical animal models.
Any clinical trials that we may conduct may not demonstrate the safety and efficacy profiles necessary to obtain regulatory approval to market our product candidates. As we continue developing our product candidates, serious adverse events, undesirable side effects, or unexpected characteristics may emerge, causing us to abandon these product candidates or limit their development to more narrow uses or subpopulations in which the risk-benefit ratio is more acceptable.
Patients treated with our product candidates may experience side effects or adverse events that are unrelated to our product candidates but may still impact the success of our clinical trials. The inclusion of patients with significant co-morbidities in our clinical trials may result in deaths or other adverse medical events due to an underlying condition or other therapies or medications that such patients may be using. Any of these events could prevent us from obtaining regulatory approval or achieving or maintaining market acceptance and impair our ability to commercialize our product candidates. In some instances, there can be significant variability in safety and efficacy results between different clinical trials of the same product candidate due to a variety of factors, including, but not limited to, changes in trial procedures set forth in protocols, differences in the size and type of the patient populations, changes in and adherence to the clinical trial protocols and the rate of dropout among clinical trial participants.
The commencement or completion of these planned clinical trials could be substantially delayed or prevented by many factors, including:
•further discussions with the FDA or other regulatory agencies regarding the scope or design of our clinical trials;
•the limited number of, and competition for, suitable sites to conduct our clinical trials, many of which may already be engaged in other clinical trial programs, including some that may be for the same indication as our product candidates;
•any delay or failure to obtain approval or agreement to commence a clinical trial in any of the countries where enrollment is planned;
•inability to obtain sufficient funds required for a clinical trial;
•clinical holds on, or other regulatory objections to, a new or ongoing clinical trial;
•delay or failure to manufacture sufficient supplies of the product candidate for our clinical trials;
•delay or failure to reach agreement on acceptable clinical trial agreement terms or clinical trial protocols with prospective sites or CROs, the terms of which can be subject to extensive negotiation and may vary significantly among different sites or CROs;
•delay or failure to obtain IRB approval to conduct a clinical trial at a prospective site;
•slower than expected rates of patient recruitment and enrollment;
•failure of patients to complete the clinical trial;
•the inability to enroll a sufficient number of patients in studies to ensure adequate statistical power to detect statistically significant treatment effects;
•unforeseen safety issues, including severe or unexpected drug-related adverse effects experienced by patients, including possible deaths;
•lack of efficacy during clinical trials;
•termination of our clinical trials by one or more clinical trial sites;
•inability or unwillingness of patients or clinical investigators to follow our clinical trial protocols;
•inability to monitor patients adequately during or after treatment by us or our CROs;
•our CROs or clinical study sites failing to comply with the trial protocol or regulatory requirements or meet their contractual obligations to us in a timely manner, or at all, deviating from the protocol or dropping out of a study;
•the inability to address any noncompliance with regulatory requirements or safety concerns that arise during the course of a clinical trial;
•third-party contractors becoming debarred or suspended or otherwise penalized by the FDA or foreign health authorities for violations of applicable regulatory requirements;
•delays in the testing, validation, manufacturing and delivery of our product candidates to the clinical trial sites, including due to a facility manufacturing any of our product candidates or any of their components being ordered by the FDA or foreign health authorities to temporarily or permanently shut down due to violations of cGMP regulations or other applicable requirements, or cross-contaminations of product candidates in the manufacturing process;
•the need to repeat or terminate clinical trials as a result of inconclusive or negative results or unforeseen complications in testing;
•our clinical trials may be suspended or terminated upon a breach or pursuant to the terms of any agreement with, or for any other reason by, current or future strategic partners that have responsibility for the clinical development of any of our product candidates; and
•receiving untimely or unfavorable feedback from applicable regulatory authorities regarding the trial or requests from regulatory authorities to modify the design of a trial.
We could also experience delays in physicians enrolling patients in clinical trials of our product candidates in lieu of prescribing existing treatments or other clinical trials. Furthermore, a clinical trial may be suspended or terminated by us, the IRBs for the institutions in which such trials are being conducted, the Data Monitoring Committee for such trial, or by the FDA or foreign health authorities 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 foreign health authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a product candidate, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. If we experience termination of, or delays in the completion of, any clinical trial of our product candidates, the commercial prospects for our product candidates will be harmed, and our ability to generate product revenue will be delayed. In addition, any delays in completing our clinical trials will increase our costs, slow down our product development and approval process and jeopardize our ability to commence product sales and generate revenue.
Securing regulatory approval also requires the submission of information about the manufacturing processes and inspection of manufacturing facilities by the relevant regulatory authority. The FDA or foreign health authorities may fail to approve our
manufacturing processes or facilities, whether run by us or our contract manufacturing organizations. In addition, if we make manufacturing changes to our product candidates in the future, we may need to conduct additional preclinical and/or clinical studies to bridge our modified product candidates to earlier versions.
Changes in regulatory requirements, policies and guidelines may also occur and we may need to significantly amend clinical trial protocols to reflect these changes with appropriate regulatory authorities. These changes may require us to renegotiate terms with CROs or resubmit clinical trial protocols to IRBs for re-examination, which may impact the costs, timing or successful completion of a clinical trial. Our clinical trials may be suspended or terminated at any time by the FDA, other regulatory authorities, the IRB overseeing the clinical trial at issue, any of our clinical trial sites with respect to that site, or us.
Any failure or significant delay in commencing or completing clinical trials for our product candidates would adversely affect our ability to obtain regulatory approval, and our commercial prospects and ability to generate product revenue will be diminished.
In addition, even if the trials are successfully completed, clinical data are often susceptible to varying interpretations and analyses, and we cannot guarantee that the FDA or foreign health authorities will interpret the results as we do, and more trials could be required before we submit our product candidates for approval. We cannot guarantee that the FDA or foreign health authorities will view any of our product candidates as having adequate safety and efficacy profiles even if favorable results are observed in these clinical trials, and we may receive unexpected or unfavorable feedback from the FDA or foreign health authorities regarding satisfaction of safety, purity and potency (including clinical efficacy), amongst other factors. To the extent that the results of the trials are not satisfactory to the FDA or foreign health authorities for support of a marketing application, approval of our product candidates may be significantly delayed, or we may be required to expend significant additional resources, which may not be available to us, to conduct additional trials in support of potential approval of our product candidates.
Our long-term prospects depend in part upon discovering, developing and commercializing additional product candidates, which may fail in development or suffer delays that adversely affect their commercial viability.
Our future operating results are dependent in part on our ability to successfully discover, develop, obtain regulatory approval for and commercialize product candidates beyond those we currently have in clinical development. A product candidate can unexpectedly fail at any stage of preclinical and clinical development. Our investments in our early-stage research and development efforts may not yield any promising product candidates. Even if our research and development efforts yield product candidates that advance into clinical studies, the historical failure rate for product candidates is high due to risks relating to safety, efficacy, clinical execution, changing standards of medical care and other unpredictable variables. The results from preclinical testing or early clinical trials of a product candidate may not be predictive of the results that will be obtained in later stage clinical trials of the product candidate.
The success of other product candidates we may develop will depend on many factors, including the following:
•generating sufficient data to support the initiation or continuation of clinical trials;
•obtaining regulatory permission to initiate clinical trials;
•contracting with the necessary parties to conduct clinical trials;
•successful enrollment of patients in, and the completion of, clinical trials on a timely basis;
•the timely manufacture of sufficient quantities of the product candidate for use in clinical trials; and
•adverse events in the clinical trials.
Even if we successfully advance any other product candidates into clinical development, their success will be subject to all of the clinical, regulatory and commercial risks described elsewhere in this “Risk Factors” section. Accordingly, we cannot assure you that we will ever be able to discover, develop, obtain regulatory approval of, commercialize or generate significant revenue from our other product candidates.
If we, or any of our partners, are unable to enroll patients in clinical trials, we will be unable to complete these trials on a timely basis or at all.
Patient enrollment, a significant factor in the timing of clinical trials, is affected by many factors including the size and nature of the patient population, the proximity of subjects to clinical sites, the eligibility criteria for the trial, the design of the clinical
trial, ability to obtain and maintain patient consents, risk that enrolled subjects will drop out before completion, competing clinical trials and clinicians’ and patients’ perceptions as to the potential advantages of the drug being studied in relation to other available therapies, including any new drugs that may be approved for the indications we are investigating. In particular, we are developing certain of our product candidates for the treatment of rare diseases, which have limited pools of patients from which to draw for clinical testing. If we, or any of our strategic partners that perform clinical tests for our product candidates, are unable to enroll a sufficient number of patients to complete clinical testing, we will be unable to gain marketing approval for such product candidates and our business will be harmed.
In addition, the U.S. federal Right to Try Act, among other things, provides a federal framework for patients to access certain investigational new drug products that have completed a Phase 1 clinical trial. Under certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without obtaining FDA approval under the FDA expanded access program. While there is no obligation to make product candidates available to eligible patients as a result of the Right to Try Act, new and emerging legislation regarding expanded access to unapproved drugs could negatively impact enrollment in our clinical trials and our business in the future.
The design or our execution of clinical trials may not support regulatory approval.
The design or execution of a clinical trial can determine whether its results will support regulatory approval, and flaws in the design or execution of a clinical trial may not become apparent until the clinical trial is well advanced. In some instances, there can be significant variability in safety or efficacy results between different trials of the same product candidate due to numerous factors, including changes in trial protocols, differences in size and type of the patient populations, adherence to the dosing regimen and other trial protocols and the rate of dropout among clinical trial participants. We do not know whether any Phase 2, Phase 3 or other clinical trials we or any of our strategic partners may conduct will demonstrate consistent or adequate efficacy and safety to obtain regulatory approval to market our product candidates.
Further, the FDA and comparable foreign regulatory authorities have substantial discretion in the approval process and in determining when or whether regulatory approval will be obtained for any of our product candidates. Our product candidates may not be approved even if they achieve their primary endpoints in any Phase 3 clinical trials or registration trials. The FDA or other non-U.S. regulatory authorities may disagree with our trial design and our interpretation of data from preclinical studies and clinical trials. In addition, any of these regulatory authorities may change requirements for the approval of a product candidate even after reviewing and providing comments or advice on a protocol for a pivotal Phase 3 clinical trial that has the potential to result in FDA or other agencies’ approval. In addition, any of these regulatory authorities may also approve a product candidate for fewer or more limited indications than we request or may grant approval contingent on the performance of costly post-marketing clinical trials. The FDA or other non-U.S. regulatory authorities may not approve the labeling claims that we believe would be necessary or desirable for the successful commercialization of our product candidates.
Interim, preliminary or top-line data from our clinical trials that we announce or publish from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data.
From time to time, we may publish interim, preliminary or top-line data from clinical trials. Interim data from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available. Preliminary or top-line data also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary or top-line data previously published. As a result, interim, preliminary and top-line data should be viewed with caution until the final data are available. Adverse differences between interim, preliminary or top-line data and final data could significantly harm our reputation and business prospects. Moreover, preliminary, interim and top-line data are subject to the risk that one or more of the clinical outcomes may materially change as more patient data become available when patients mature on study, patient enrollment continues or as other ongoing or future clinical trials with a product candidate further develop. Past results of clinical trials may not be predictive of future results.
In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is based on what is typically more extensive information, and you or others may not agree with what we determine is the material or otherwise appropriate information to include in our disclosure. Any information we determine not to disclose may ultimately be deemed significant with respect to future decisions, conclusions, views, activities or otherwise regarding a particular product candidate or our business. Similarly, even if we are able to complete our planned and ongoing preclinical studies and clinical trials of our product candidates according to our current development timeline, the positive results from such preclinical studies and clinical trials of our product candidates may not be replicated in subsequent preclinical studies or clinical trial results.
Many companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in late-stage clinical trials after achieving positive results in early-stage development and we cannot be certain that we will not face similar setbacks. These setbacks have been caused by, among other things, preclinical and other nonclinical findings made while clinical trials were underway or safety or efficacy observations made in preclinical studies and clinical trials, including previously unreported adverse events. Moreover, preclinical, nonclinical and clinical data are often susceptible to varying interpretations and analyses and many companies that believed their product candidates performed satisfactorily in preclinical studies and clinical trials nonetheless failed to obtain FDA or other regulatory approval.
The Fast Track and Breakthrough Therapy designations we have received for zanidatamab may not result in faster development, regulatory review or approval process.
The FDA has granted Fast Track designations to zanidatamab for the first-line treatment of patients with HER2-overexpressing GEA in combination with standard of care chemotherapy and for previously treated or recurrent gene-amplified BTC. These Fast Track designations do not ensure that we will experience a faster development, regulatory review or approval process compared to conventional FDA procedures or that we will ultimately obtain regulatory approval. Additionally, the FDA may withdraw Fast Track designation if it believes that the designation is no longer supported by data from our clinical development program. The FDA also granted Breakthrough Therapy designation for zanidatamab for treatment of patients with previously treated HER2 gene-amplified locally advanced/unresectable or metastatic BTC. While we anticipate meeting with the FDA in 2023 to discuss the data readout from the HERIZON-BTC-01 study in support of submitting a BLA for zanidatamab in patients with previously treated HER2 gene-amplified BTC, the receipt of a Breakthrough Therapy designation for a product candidate may not ultimately result in a faster development process or review, and it does not in any way assure approval of a product candidate by the FDA. In addition, designation as a Breakthrough Therapy is within the discretion of the FDA and the FDA may decide to rescind a Breakthrough Therapy designation if it believes that a designated product candidate no longer meets the conditions for qualification of this program. If our clinical development program is suspended, terminated, or put on clinical hold due to unexpected adverse events or other issues, including clinical supply issues, we may not realize all the benefits associated with the Fast Track designation. Furthermore, Fast Track designation does not change the standards for approval, and the designation alone does not guarantee qualification for the FDA’s priority review procedures.
Zanidatamab has also been granted Breakthrough Therapy designation from the Center for Drug Evaluation in China for treating patients with BTC who have failed prior systemic therapies.
Development of product candidates in combination with other therapies could expose us to additional risks.
Even if any of our product candidates were to receive marketing approval or be commercialized for use in combination with other existing therapies, we would continue to be subject to the risks that the FDA, the EMA or other comparable foreign regulatory authorities could revoke approval of the therapy used in combination with any of our product candidates, or safety, efficacy, manufacturing or supply issues could arise with these existing therapies. In addition, it is possible that existing therapies with which our product candidates are approved for use could themselves fall out of favor or be relegated to later lines of treatment. This could result in the need to identify other combination therapies for our product candidates or our own products being removed from the market or being less successful commercially. We may also evaluate our product candidates in combination with one or more other cancer therapies that have not yet been approved for marketing by the FDA, EMA or comparable foreign regulatory authorities. We will not be able to market and sell any product candidate in combination with any such unapproved cancer therapies that do not ultimately obtain marketing approval. If the FDA, EMA or other comparable foreign regulatory authorities do not approve or revoke their approval of these other therapies, or if safety, efficacy, commercial adoption, manufacturing or supply issues arise with the therapies we choose to evaluate in combination with any other product candidate, we may be unable to obtain approval of or successfully market any one or all of the product candidates we develop.
Additionally, if the third-party providers of therapies or therapies in development used in combination with our product candidates are unable to produce sufficient quantities for clinical trials or for commercialization of our product candidates, or if the cost of combination therapies are prohibitive, our development and commercialization efforts would be impaired, which would have an adverse effect on our business, financial condition, results of operations and growth prospects.
Disruptions at the FDA and other government agencies caused by funding shortages or global health concerns could hinder their ability to hire, retain or deploy key leadership and other personnel, or otherwise prevent new or modified product candidates from being developed, or approved or commercialized in a timely manner or at all, which could negatively impact our business.
The ability of the FDA to review and clear or approve new product candidates can be affected by a variety of factors, including government budget and funding levels, statutory, regulatory, and policy changes, the FDA’s ability to hire and retain key personnel and accept the payment of user fees, and other events that may otherwise affect the FDA’s ability to perform routine
functions. In addition, government funding of other government agencies that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable. Disruptions at the FDA and other agencies, including delays or disruptions due to the COVID-19 pandemic, travel restrictions, staffing shortages, government shutdowns and furloughs, may also slow the time necessary for new product candidates to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. In response to the COVID-19 pandemic and travel restrictions, the FDA has issued industry guidance regarding plans to employ remote interactive evaluations and risk management methods, among other considerations, to meet user fee commitments and goal dates as well as plans toward resuming standard operational levels. Recently, President Biden announced that the administration intends to end the COVID-19 national and public health emergencies on May 11, 2023. The full impact of this termination of the public health emergencies on the FDA and other regulatory policies and operations are unclear. However, if global health concerns continue to prevent the FDA or other regulatory authorities from conducting their regular inspections, reviews, or other regulatory activities, or if the FDA and other agencies experience other delays, backlogs or disruptions, it could significantly impact the ability of the FDA or other regulatory authorities to timely review and process our regulatory submissions, which could have a material adverse effect on our business.
Successful development of our current and future product candidates is uncertain and we may discontinue or reprioritize the development of any of our product candidates at any time, at our discretion.
Before obtaining regulatory approval for the commercial distribution of our product candidates, we must conduct, at our own expense, extensive preclinical tests and clinical trials to demonstrate the safety and efficacy of our product candidates in humans. Preclinical and clinical testing is expensive, difficult to design and implement, can take many years to complete and is uncertain as to outcome. Additionally, the results from nonclinical testing or early clinical trials of a product candidate may not predict the results that will be obtained in subsequent human clinical trials of that product candidate. There is a high failure rate for drugs proceeding through clinical studies. A number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in clinical development even after achieving promising results in earlier studies, and any such setbacks in any future clinical development could have a material adverse effect on our business and operating results. Alternatively, management may elect to discontinue development of certain product candidates to accommodate a shift in corporate strategy, despite positive clinical results. Based on our operating results and business strategy, among other factors, we may discontinue the development of any of our product candidates under development or reprioritize our focus on other product candidates at any time and at our discretion.
Additionally, because we have limited financial and managerial resources, we focus on research programs, therapeutic platforms and product candidates that we identify for specific indications. As a result, we may forgo or delay pursuit of opportunities with other therapeutic platforms or product candidates or for other indications that later prove to have greater commercial potential. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights.
Our product candidates may have undesirable side effects that may delay or prevent marketing approval or, if approval is received, require them to be taken off the market, require them to include safety warnings or otherwise limit their sales; no regulatory agency has made any determination that any of our product candidates are safe or effective for use by the general public for any indication.
All of our product candidates are still in preclinical or clinical development. Consequently, all of our product candidates are required to undergo ongoing safety testing in humans as part of clinical trials. Unforeseen side effects from any of our product candidates could arise either during clinical development or, if approved by regulatory authorities, after the approved product has been marketed. Zanidatamab and zanidatamab zovodotin continue to be evaluated in clinical trials, and the results of these and future clinical trials may show that zanidatamab, zanidatamab zovodotin or our other product candidates cause undesirable or unacceptable side effects, which could interrupt, delay or halt clinical trials, and result in delay of, or failure to obtain, marketing approval from the FDA and other regulatory authorities, or result in marketing approval from the FDA and other regulatory authorities with restrictive label warnings, limited patient populations or potential product liability claims. Even if we believe that our clinical trials and preclinical studies demonstrate the safety and efficacy of our product candidates, only the FDA and other comparable regulatory agencies may ultimately make such determination. No regulatory agency has made any such determination that any of our product candidates are safe or effective for use by the general public for any indication.
If any of our product candidates receive marketing approval and we or others later identify undesirable or unacceptable side effects caused by such products:
•regulatory authorities may require us to take our approved product off the market;
•regulatory authorities may require the addition of labeling statements, specific warnings, a contraindication or field alerts to physicians and pharmacies, or impose a risk evaluation and mitigation strategy that includes restrictions and conditions on product distribution, prescribing and/or dispensing;
•we may be required to change the way the product is administered, conduct additional clinical trials or change the labeling of the product;
•we may be subject to limitations on how we may promote the product;
•sales of the product may decrease significantly;
•we may be subject to litigation or product liability claims; and
•our reputation may suffer.
Any of these events could prevent us or our current or future strategic partners from achieving or maintaining market acceptance of the affected product or could substantially increase commercialization costs and expenses, which in turn could delay or prevent us from generating revenue from the sale of any future products.
We face significant competition, and if our competitors develop and market products that are more effective, safer or less expensive than our product candidates, our commercial opportunities will be negatively impacted.
The life sciences industry is highly competitive and subject to rapid and significant technological change. We are currently developing biotherapeutics that will compete with other drugs and therapies that currently exist or are being developed. Products we may develop in the future are also likely to face competition from other drugs and therapies, some of which we may not currently be aware. We have competitors both in the United States and internationally, including major multinational pharmaceutical companies, established biotechnology companies, specialty pharmaceutical companies, universities and other research institutions. Many of our competitors have significantly greater financial, manufacturing, marketing, drug development, technical and human resources than we do. Large pharmaceutical companies, in particular, have extensive experience in clinical testing, obtaining regulatory approvals, recruiting patients and in manufacturing pharmaceutical products. These companies also have significantly greater research and marketing capabilities than we do and may also have products that have been approved or are in late stages of development and collaborative arrangements in our target markets with leading companies and research institutions. Established pharmaceutical companies may also invest heavily to accelerate discovery and development of novel compounds or to in-license novel compounds that could make the product candidates that we develop obsolete. As a result of all of these factors, our competitors may succeed in obtaining patent protection or FDA approval or discovering, developing and commercializing products in our field before we do.
Specifically, there are a large number of companies developing or marketing treatments for cancer and autoimmune disorders, including many major pharmaceutical and biotechnology companies. These treatments consist both of small-molecule drug products, as well as biologics that work by using various antibody therapeutic platforms to address specific cancer targets. For additional information relating to the competitive environment we operate in, see Item 1. “Business - Competition.”
Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, more convenient or less expensive than any products that we may develop. Our competitors also may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for our product candidates, which could result in our competitors establishing a strong market position before we are able to enter the market.
Smaller and other early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These third parties compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs. In addition, the biopharmaceutical industry is characterized by rapid technological change. If we fail to stay at the forefront of technological change, we may be unable to compete effectively. Technological advances or products developed by our competitors may render our technologies or product candidates obsolete, less competitive or not economical.
In addition, we expect to compete with biosimilar versions of already approved products like trastuzumab or pertuzumab, and even if our product candidates achieve marketing approval, they may be challenged to achieve a price premium over competitive biosimilar products and will compete for market share with them.
The Biologics Price Competition and Innovation Act of 2009, which is included in the PPACA, authorized the FDA to approve similar versions of innovative biologics, commonly known as biosimilars. Under the PPACA, a manufacturer may submit an application for licensure of a biologic product that is “biosimilar to” or “interchangeable with” a previously approved biologic product or “reference product.” Manufacturers may not submit an application for a biosimilar to the FDA until four years following approval of the reference product, and the FDA may not approve a biosimilar product until 12 years from the date on which the reference product was approved. Even if our product candidates, if approved, are deemed to be reference products eligible for exclusivity, another company could market a competing version of that product if the FDA approves a full BLA for such product containing the sponsor’s own preclinical data and data from adequate and well-controlled clinical trials to demonstrate the safety, purity and potency of their product. Additionally, from time to time, there are proposals to repeal or modify the PPACA, including proposals that could significantly shorten the exclusivity period for biologics.
If any of our product candidates receive regulatory approval, the approved products may not achieve broad market acceptance among physicians, patients, the medical community and third-party payors, in which case revenue generated from their sales would be limited.
The commercial success of our product candidates will depend upon their acceptance among physicians, patients and the medical community. The degree of market acceptance of our product candidates will depend on a number of factors, including:
•limitations or warnings contained in the approved labeling for a product candidate;
•changes in the standard of care for the targeted indications for any of our product candidates;
•limitations in the approved clinical indications for our product candidates;
•demonstrated clinical safety and efficacy compared to other products;
•sales, marketing and distribution support;
•availability of coverage and extent of reimbursement from managed care plans and other third-party payors;
•timing of market introduction and perceived effectiveness of competitive products;
•availability of alternative therapies at similar or lower cost, including generic, biosimilar and over-the-counter products;
•the extent to which the product candidate is approved for inclusion on formularies of hospitals and managed care organizations;
•whether the product is designated under physician treatment guidelines as a first-line therapy or as a second- or third-line therapy for particular diseases;
•whether the product can be used effectively with other therapies to achieve higher response rates;
•adverse publicity about our product candidates or favorable publicity about competitive products;
•convenience and ease of administration of our products; and
•potential product liability claims.
If any of our product candidates are approved, but do not achieve an adequate level of acceptance by physicians, patients and the medical community, we may not generate sufficient revenue from these products, and we may not become or remain profitable. In addition, efforts to educate the medical community and third-party payors on the benefits of our product candidates may require significant resources and may never be successful.
We may be unable to obtain orphan drug exclusivity in specific indications for zanidatamab or in future product candidates that we may develop. If our competitors are able to obtain orphan product exclusivity for their products in specific indications, we may not be able to have competing products approved in those indications by the applicable regulatory authority for a significant period of time.
The FDA has granted Orphan Drug Designation to zanidatamab for the treatment of BTC and gastric cancer, including cancer of the gastroesophageal junction, the EMA has granted Orphan Drug Designation to zanidatamab for the treatment of gastric cancer and BTC, and we may seek Orphan Drug Designation for additional indications in the future. Orphan Drug Designation neither shortens the development time or regulatory review time of a drug nor gives the drug any advantage in the regulatory review or approval process.
Generally, if a product candidate with an Orphan Drug Designation subsequently receives the first marketing approval for the indication for which it has such designation, the product is entitled to a period of marketing exclusivity, which precludes the EMA or the FDA from approving another marketing application for the same drug for the same indication for that time period. The applicable period is seven years in the United States and ten years in Europe. The European exclusivity period can be reduced to six years if a product no longer meets the criteria for Orphan Drug Designation or if the product is sufficiently profitable so that market exclusivity is no longer justified. Orphan drug exclusivity may be lost if the FDA or EMA determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the product to meet the needs of patients with the rare disease or condition. The loss of Orphan Drug Designation could have a negative effect on our ability to successfully commercialize our product candidates, earn revenues and achieve profitability.
Even if orphan drug exclusivity for zanidatamab is obtained, or is obtained for any other product candidates that receive an Orphan Drug Designation in the future, that exclusivity may not effectively protect the product from competition because different drugs with different active moieties can be approved for the same condition. Further, in the United States, even after an orphan drug is approved, the FDA can subsequently approve the same drug for the same condition submitted by a competitor if the FDA concludes that the later drug is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care. If we are unable to manufacture sufficient supply of our product to meet the needs of patients, the FDA can withdraw our orphan exclusive marketing rights or approve another marketing application for the same drug product before the expiration of the exclusivity period.
Further, in Catalyst Pharms., Inc. v. Becerra, 14 F.4th 1299 (11th Cir. 2021), the court disagreed with the FDA’s longstanding position that the orphan drug exclusivity only applies to the approved use or indication within an eligible disease, and not to all uses or indications within the entire disease or condition. In particular, the circuit court held that the orphan drug exclusivity for Catalyst’s drug blocked the FDA’s approval of another drug for all uses or indications within the same orphan-designated disease, Lambert-Eaton myasthenic syndrome (LEMS), even though Catalyst’s drug was approved at that time only for use in the treatment of LEMS in adults. Accordingly, the court ordered the FDA to set aside the approval of a drug indicated for LEMS in children. This decision created uncertainty in the application of the orphan drug exclusivity. On January 24, 2023, the FDA published a notice in the Federal Register to clarify that while the agency complies with the court’s order in Catalyst, the FDA intends to continue to apply its longstanding interpretation of the regulations to matters outside of the scope of the Catalyst order - that is, the agency will continue tying the scope of orphan drug exclusivity to the uses or indications for which a drug is approved, which permits other sponsors to obtain approval of a drug for new uses or indications within the same orphan designated disease or condition that have not yet been approved. It is unclear how future litigation, legislation, agency decisions, and administrative actions will impact the scope of the orphan drug exclusivity.
Even if we obtain FDA approval of any of our product candidates, we may never obtain approval or commercialize such products outside of the United States, which would limit our ability to realize their full market potential.
In order to market any products outside of the United States, we must establish and comply with numerous and varying regulatory requirements of other countries regarding safety and efficacy. Clinical trials conducted in one country may not be accepted by regulatory authorities in other countries, and regulatory approval in one country does not mean that regulatory approval will be obtained in any other country. Approval procedures vary among countries and can involve additional product testing and validation and additional administrative review periods. Seeking foreign regulatory approvals could result in significant delays, difficulties and costs for us and may require additional preclinical studies or clinical trials, which would be costly and time consuming. Regulatory requirements can vary widely from country to country and region to region and could delay or prevent the introduction of our products in those countries. Satisfying these and other regulatory requirements is costly, time consuming, uncertain and subject to unanticipated delays. In addition, our failure to obtain regulatory approval in any country may delay or have negative effects on the process for regulatory approval in other countries. We do not have any product candidates approved for sale in any jurisdiction, including international markets, and we do not have experience in obtaining regulatory approval in international markets. If we fail to comply with regulatory requirements in international markets or to obtain and maintain required approvals, our target market will be reduced and our ability to realize the full market potential of our products will be harmed.
Our ability to eventually generate significant revenues from product sales will depend on a number of factors, including:
•successful completion of preclinical studies;
•submission of INDs or other regulatory applications for our planned clinical trials or future clinical trials and authorizations from regulators to initiate clinical studies;
•successful enrollment in, and completion of, clinical trials;
•achieving favorable results from clinical trials;
•receipt of marketing approvals from applicable regulatory authorities;
•establishing and maintaining sufficient manufacturing capabilities, whether internally or with third parties, for clinical and commercial supply;
•obtaining pricing, reimbursement, and hospital formulary access;
•establishing sales, marketing and distribution capabilities and launching commercial sales of our products, if and when approved, whether alone or in combination with other products;
•sufficiency of our financial and other resources to complete the necessary preclinical studies and clinical trials and commercialization activities;
•effectively competing with other therapies;
•developing and implementing successful marketing and reimbursement strategies;
•obtaining and maintaining patent, trade secret and other intellectual property protection and regulatory exclusivity for our product candidates; and
•maintaining a continued acceptable safety profile of any product following approval, if any.
If we do not achieve one or more of these requirements in a timely manner, we could experience significant delays or an inability to successfully commercialize our product candidates, which would materially harm our business.
We cannot be certain that our clinical trials will be initiated and completed on time, if at all, or whether our planned clinical strategy will be acceptable to the FDA or foreign health authorities. To become and remain profitable, we must develop, obtain approval for and eventually commercialize products, if approved, that generate significant revenue. In addition, it is not uncommon for product candidates to exhibit unforeseen safety issues or inadequate efficacy when tested in humans despite promising results in preclinical animal models or earlier trials, and we may ultimately be unable to demonstrate adequate safety and efficacy of our product candidates to obtain marketing approval. Even if we obtain approval and begin commercializing one or more of our product candidates, we may never generate revenue that is significant or large enough to achieve profitability.
Even if we succeed in commercializing one or more of our product candidates, we will continue to incur substantial research and development, manufacturing and other expenditures to develop and market additional product candidates. Our failure to become or remain profitable would decrease the value of the company and could impair our ability to raise capital, maintain our research and development efforts, expand our business or continue our operations.
Reimbursement decisions by third-party payors may have an adverse effect on pricing and market acceptance. If there is not sufficient reimbursement for our products, it is less likely that our products will be widely used.
The regulations that govern marketing approvals, pricing, coverage and reimbursement for new drugs vary widely from country to country. Many countries require approval of the sale price of a drug before it can be marketed. The pricing review period begins after marketing or product licensing approval is granted in most cases. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we might obtain regulatory approval for a product in a particular country, but then be subject to price regulations that delay our commercial launch of the product and negatively impact the revenues we are able to generate from the sale of the product in that country.
Our ability to commercialize any products successfully also will depend in part on the extent to which coverage and adequate reimbursement for these products and related treatments will be available from government health administration authorities, private health insurers and other third-party payors. In many jurisdictions, a product candidate must be approved for reimbursement before it can be approved for sale in that jurisdiction. Obtaining coverage and reimbursement approval of a product from a government or other third-party payor is a time-consuming and costly process that could require us to provide to the payor supporting scientific, clinical and cost-effectiveness data for the use of our products. If we are not currently capturing the scientific and clinical data that will be required for reimbursement approval, we may be required to conduct additional trials, which may delay or suspend reimbursement approval. Additionally, in the United States, no uniform policy of coverage and reimbursement for products exists among third-party payors. Therefore, coverage and reimbursement for products can differ significantly from payor to payor. As a result, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific and clinical support for the use of a product candidate that receives regulatory approval to each payor separately, with no assurance that coverage and adequate reimbursement will be obtained.
Even if our product candidates are approved for sale by the appropriate regulatory authorities, market acceptance and sales of these products will depend on reimbursement policies and may be affected by future healthcare reform measures. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which drugs they will reimburse and establish payment levels. We cannot be certain that reimbursement will be available for any products that we develop. If reimbursement is not available or is available on a limited basis, we may not be able to successfully commercialize any of our approved products.
In the United States, the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, also called the Medicare Modernization Act (“MMA”), changed the way Medicare covers and pays for pharmaceutical products. The legislation established Medicare Part D, which expanded Medicare coverage for outpatient prescription drug purchases by the elderly but provided authority for limiting the number of drugs that will be covered in any therapeutic class. The MMA also introduced a new reimbursement methodology based on average sales prices for physician-administered drugs. We expect to experience pricing pressures in connection with the sale of any products that we develop, due to the trend toward managed healthcare, the increasing influence of health maintenance organizations and additional legislative proposals. In August 2022, Congress passed the Inflation Reduction Act of 2022, which includes prescription drug provisions that have significant implications for the pharmaceutical industry and Medicare beneficiaries, including allowing the federal government to negotiate a maximum fair price for certain high-priced single-source Medicare drugs, imposing penalties and excise tax for manufacturers that fail to comply with the drug price negotiation requirements, requiring inflation rebates for all Medicare Part B and Part D drugs, with limited exceptions, if their drug prices increase faster than inflation, and redesigning Medicare Part D to reduce out-of-pocket prescription drug costs for beneficiaries, among other changes. The impact of these legislative, executive, and administrative actions and any future healthcare measures and agency rules implemented by the Biden administration on us and the pharmaceutical industry as a whole is unclear. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our product candidates if approved.
There may be significant delays in obtaining coverage and reimbursement for newly approved drugs, and coverage may be more limited than the purposes for which the drug is approved by the FDA, EMA or other regulatory authorities. Moreover, eligibility for coverage and reimbursement does not imply that a drug will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution expenses. Interim reimbursement levels for new drugs, if applicable, may also be insufficient to cover our and any collaborator’s costs and may not be made permanent. Reimbursement rates may vary according to the use of the drug and the clinical setting in which it is used, may be based on reimbursement levels already set for lower cost drugs and may be incorporated into existing payments for other services. Net prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors and by any future relaxation of laws that currently restrict imports of drugs from countries where they may be sold at lower prices than in the United States. Our or any collaborator’s inability to promptly obtain coverage and profitable payment rates from both government-funded and private payors for any approved products that we or our strategic partners develop could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize product candidates and our overall financial condition.
If the market opportunities for any product that we or our strategic partners develop are smaller than we believe they are, our revenue may be adversely affected and our business may suffer.
We intend to initially focus our independent product candidate development on treatments for oncology. Our projections of addressable patient populations that have the potential to benefit from treatment with our product candidates are based on estimates. If our projections are inaccurate, the market opportunities for any of our product candidates could be significantly diminished and have an adverse material impact on our business.
We may not be successful in our efforts to use our therapeutic platforms to build a pipeline of product candidates.
We intend to use our therapeutic platforms to build a pipeline of product candidates and progress these product candidates through clinical development for the treatment of a variety of diseases. Although our research and development efforts to date have resulted in a pipeline of product candidates directed at various cancers, we may not be able to develop product candidates that are safe and effective. In addition, although we expect that our therapeutic platforms will allow us to develop further product candidates, they may not prove to be successful at doing so. Even if we are successful in continuing to build our pipeline, the potential product candidates that we identify may not be suitable for clinical development, including as a result of being shown to have harmful side effects or other characteristics that indicate that they are unlikely to be products that will receive marketing approval and achieve market acceptance. If we do not continue to successfully develop and begin to commercialize product candidates, we will face difficulty in obtaining product revenue in future periods, which could result in significant harm to our financial position and adversely affect our stock price.
Even if we receive regulatory approval to commercialize any of the product candidates that we develop, we will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense.
Any regulatory approvals that we receive for our product candidates may be subject to limitations on the approved indicated uses for which the product may be marketed or subject to certain conditions of approval, and may contain requirements for potentially costly post-approval trials, including Phase 4 clinical trials, and surveillance to monitor the safety and efficacy of the marketed product.
For any approved product, we will be subject to ongoing regulatory obligations and extensive oversight by regulatory authorities, including with respect to manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion and recordkeeping for the product. These requirements include submissions of safety and other post-approval information and reports, as well as continued compliance with cGMP and good clinical practice (“GCP”), for any clinical trials that we or our strategic partners conduct after approval. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in, among other things:
•restrictions on the marketing or manufacturing of the product;
•withdrawal of the product from the market or voluntary or mandatory product recalls;
•fines, warning letters or holds on clinical trials;
•refusal by the FDA, EMA or another applicable regulatory authority to approve pending applications or supplements to approved applications filed by us or our strategic partners, or suspension or revocation of product license approvals;
•product seizure or detention, or refusal to permit the import or export of products; and
•injunctions or the imposition of civil or criminal penalties.
Occurrence of any of the foregoing could have a material and adverse effect on our business and results of operations. Further, the FDA’s or other ex-U.S. regulators’ policies may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained, which would adversely affect our business, prospects and ability to achieve or sustain profitability.
The FDA strictly regulates manufacturers’ promotional claims of drug products. In particular, a drug product may not be promoted by manufacturers for uses that are not approved by the FDA, as reflected in the FDA-approved labeling, although healthcare professionals are permitted to use drug products for off-label uses. The FDA, the Department of Justice, the Inspector General of the Department of Health and Human Services, among other government agencies, actively enforce the laws and regulations prohibiting manufacturers’ promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant liability, including large civil and criminal fines, penalties, and enforcement actions. The FDA has also imposed consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed for companies that engaged in such prohibited activities. If we cannot successfully manage the promotion of our approved product candidates, we could become subject to significant liability, which would materially adversely affect our business and financial condition.
If any product liability lawsuits are successfully brought against us or any of our strategic partners, we may incur substantial liabilities and may be required to limit commercialization of our product candidates.
We face an inherent risk of product liability lawsuits related to the testing of our product candidates in seriously ill patients, and will face an even greater risk if product candidates are approved by regulatory authorities and introduced commercially. Product liability claims may be brought against us or our strategic partners by participants enrolled in our clinical trials, patients, health care providers or others using, administering or selling any of our future approved products. If we cannot successfully defend ourselves against any such claims, we may incur substantial liabilities. Regardless of their merit or eventual outcome, liability claims may result in:
•decreased demand for any future approved products;
•injury to our reputation;
•withdrawal of clinical trial participants;
•termination of clinical trial sites or entire trial programs;
•increased regulatory scrutiny;
•significant litigation costs;
•substantial monetary awards to, or costly settlement with, patients or other claimants;
•product recalls or a change in the indications for which they may be used;
•loss of revenue;
•diversion of management and scientific resources from our business operations; and
•the inability to commercialize our product candidates.
We may need to have in place increased product liability coverage when we begin the commercialization of our product candidates. Insurance coverage is becoming increasingly expensive. As a result, we may be unable to maintain or obtain sufficient insurance at a reasonable cost to protect us against losses that could have a material adverse effect on our business. A successful product liability claim or series of claims brought against us, particularly if judgments exceed any insurance coverage we may have, could decrease our cash resources and adversely affect our business, financial condition and results of operation.
Patients with cancer and other diseases targeted by our product candidates are often already in severe and advanced stages of disease and have both known and unknown significant pre-existing and potentially life-threatening health risks. During the course of treatment, patients may suffer adverse events, including death, for reasons that may be related to our product candidates. Such events could subject us to costly litigation, require us to pay substantial amounts of money to injured patients, delay, negatively impact or end our opportunity to receive or maintain regulatory approval to market our product candidates, or require us to suspend or abandon our commercialization efforts. Even in a circumstance in which we do not believe that an adverse event is related to our product candidates, the investigation into the circumstance may be time-consuming or inconclusive. These investigations may interrupt our sales efforts, delay our regulatory approval process in other countries, or impact and limit the type of regulatory approvals our product candidates receive or maintain. As a result of these factors, a product liability claim, even if successfully defended, could have a material adverse effect on our business, financial condition or results of operations.
If we or any of our third-party manufacturers encounter manufacturing difficulties, our ability to provide supply of our product candidates for clinical trials or our products for patients, if approved, could be delayed or prevented.
The manufacture of biological drug products is complex and requires significant expertise and capital investment, including the development of advanced manufacturing techniques, process and quality controls. Manufacturers of biologic products often encounter difficulties in production and sourcing, particularly in scaling up or out, validating the production process and assuring high reliability of the manufacturing processes (including the absence of contamination), in light of variations and supply constraints of key components. These problems include logistics and shipping, difficulties with production costs and yields, quality control, including consistency, stability, purity and efficacy of the product, product testing, operator error and availability of qualified personnel, as well as compliance with applicable federal, state and foreign regulations. If contaminants are discovered in our supply of our product candidates or in the manufacturing facilities, such manufacturing facilities may need to be closed for an extended period of time to investigate and remedy the contamination. We cannot assure you that any stability, purity, and efficacy failures, deficiencies, or other issues relating to the manufacture of our product candidates will not occur in the future. Our research and development activities also involve the controlled use of potentially hazardous substances, including chemical and biological materials, by our third-party manufacturers. While we currently outsource all manufacturing to third parties, we and our manufacturers are subject to federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of medical and hazardous materials. Although we believe that our manufacturers’ procedures for using, handling, storing and disposing of these materials comply with legally prescribed standards, we cannot completely eliminate the risk of contamination or injury, and any related liability, resulting from medical or hazardous materials.
Material modifications in methods of product candidate manufacturing or formulation may result in additional costs or delay.
As product candidates are developed through preclinical to late-stage clinical trials towards approval and commercialization, it is common that various aspects of the development program, such as manufacturing methods and formulation, are altered along the way in an effort to optimize processes and results. Such changes carry the risk that they will not achieve these intended
objectives. Any of these changes could cause our product candidates to perform differently and affect the results of planned clinical trials or other future clinical trials conducted with the altered materials. This could delay completion of clinical trials, require the conduct of bridging clinical trials or the repetition of one or more clinical trials, increase clinical trial costs, delay approval of our product candidates and jeopardize our ability, or our strategic partners’ ability, to commence product sales and generate revenue.
Strategic transactions could disrupt our business, cause dilution to our stockholders and otherwise harm our business.
We actively evaluate various strategic transactions on an ongoing basis. For example, we may acquire other businesses, products or technologies as well as pursue strategic alliances, joint ventures, investments in complementary businesses, out-licensing agreements, divestitures or other transactions. Any of these transactions could be material to our financial condition and operating results and expose us to many risks, including:
•disruption in our relationships with existing strategic partners or suppliers as a result of such a transaction;
•unanticipated liabilities related to acquired companies;
•difficulties integrating acquired personnel, technologies and operations into our existing business;
•retention of key employees;
•diversion of management time and focus from operating our business to management of strategic alliances or joint ventures or acquisition integration challenges;
•risks and uncertainties associated with the other party to such a transaction, including the prospects of that party and their existing products or product candidates and marketing approvals;
•increases in our expenses and reductions in our cash available for operations and other uses; and
•possible write-offs or impairment charges relating to acquired businesses.
Also, the anticipated benefit of any strategic transaction may not materialize or such strategic transaction may be prohibited. Additionally, future acquisitions or dispositions could result in potentially dilutive issuances of our equity securities, the incurrence of debt, contingent liabilities or amortization expenses or write-offs of goodwill, any of which could harm our financial condition. We cannot predict the number, timing or size of any future strategic alliances, joint ventures, investments, acquisitions, divestitures or other strategic transactions, or the effect that any such transactions might have on our operating results.
Many governments impose strict price controls, which may adversely affect our future profitability.
In many countries, particularly in those in the EU, prescription drug pricing and reimbursement is subject to governmental control. In those countries that impose price controls, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product. To obtain reimbursement or pricing approval in some countries, we or our strategic partners may be required to conduct a clinical trial that compares the cost-effectiveness of our product candidates to other available therapies.
Some countries require approval of the sale price of a drug before it can be marketed. In many countries, the pricing review period begins after marketing or product licensing approval is granted. In some markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we or our strategic partners might obtain marketing approval for a product candidate in a particular country, but then be subject to price regulations that delay commercial launch of the product candidate, possibly for lengthy time periods, and negatively impact the revenue that is generated from the sale of the product in that country. If reimbursement of such product candidates is unavailable or limited in scope or amount, if pricing is set at unsatisfactory levels, or if there is competition from lower priced cross-border sales, our profitability will be negatively affected.
Security breaches and incidents, loss of data and other disruptions could compromise sensitive information related to our business or protected health information or prevent us from accessing critical information and expose us to liability, which could adversely affect our business and our reputation.
In the ordinary course of our business, we and our CROs and other service providers collect, store and otherwise process petabytes of sensitive data, including legally protected health information, personal information, intellectual property and proprietary business information owned or controlled by ourselves or our strategic partners. We manage and maintain our
applications and data by utilizing a combination of on-site systems, managed data center systems and cloud-based data center systems. These applications and data encompass a wide variety of business-critical information, including research and development information, commercial information and business and financial information. We face four primary risks relative to protecting this critical information: loss of access risk, inappropriate disclosure risk, inappropriate modification risk and the risk of being unable to adequately monitor our controls over the first three risks.
Although we take measures designed to protect sensitive information from unauthorized access or disclosure, our information technology and infrastructure and those of our CROs and our other third-party service providers may utilize may be vulnerable to attacks by hackers or viruses or breached, interrupted or compromised due to inadvertent or intentional actions by our employees, contractors, business partners, and/or other third parties, or from cyber-attacks by malicious third parties (including supply chain cyber-attacks or the deployment of harmful malware, ransomware, denial-of-service attacks, social engineering and other means to affect service reliability and threaten the confidentiality, integrity and availability of information). Any such breach, incident, or interruption could compromise systems and networks used in our business and lead to the loss, destruction, alteration, prevention of access to, disclosure, or dissemination of, or damage or unauthorized access to, our data (including trade secrets or other confidential information, intellectual property, proprietary business information, and personal information) or data that is processed or maintained on our behalf, or other assets, which could result in financial, legal, business and reputational harm to us. Any such event could result in legal claims, demands and litigation or governmental investigations or other proceedings, liability under laws that protect the privacy of personal information, such as the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), and regulatory penalties and other liabilities. Although we have implemented security measures and a formal enterprise security program designed to prevent unauthorized access to sensitive data, there is no guarantee that we or our third-party service providers can protect our systems or networks or other systems or networks used in our business from security breaches, incidents, or compromises. Any loss, destruction, alteration, prevention of access to, disclosure, or dissemination of, or damage or unauthorized access to, our data or other data that is processed or maintained on our behalf could also disrupt our operations (including our ability to conduct our analyses, pay providers, conduct research and development activities, collect, process and prepare company financial information, provide information about any future products, and manage the administrative aspects of our business) and damage our reputation, any of which could adversely affect our business.
HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act (“HITECH”), and its implementing regulations, impose certain requirements relating to the privacy, security, transmission and breach reporting of individually identifiable health information upon entities subject to the law, such as health plans, healthcare clearinghouses and healthcare providers and their respective business associates and subcontractors that perform services for them that involve individually identifiable health information. Mandatory penalties for HIPAA violations can be significant, and criminal and monetary penalties, as well as injunctive relief, may be imposed for HIPAA violations. Although most drug manufacturers are not directly subject to HIPAA, prosecutors are increasingly using HIPAA-related theories of liability against drug manufacturers and their agents and we also could be subject to criminal penalties if we knowingly obtain individually identifiable health information from a HIPAA-covered entity in a manner that is not authorized or permitted by HIPAA.
Furthermore, in the event of a breach as defined by HIPAA, HIPAA regulations impose specific reporting requirements to regulators, individuals impacted by the breach and, in some cases, the media. Issuing such notifications can be costly, time and resource intensive, and can generate significant negative publicity. Breaches of HIPAA may also constitute contractual violations that could lead to contractual damages or terminations. In addition to HIPAA, other applicable data privacy and security obligations, including U.S. state data breach notification laws, may require us to notify relevant stakeholders of any security breaches or incidents that result in the unauthorized disclosure, or dissemination of, personal information. Such disclosures are costly, and the disclosures or the failure to comply with such requirements, could lead to adverse impacts.
Furthermore, the loss of clinical trial data from completed or future clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. Likewise, we rely on other third parties for the manufacture of our product candidates and to conduct clinical trials, and similar events relating to their computer systems could also have a material adverse effect on our business.
In addition, we may face increased cybersecurity risks due to our reliance on internet technology given that we have employees at three office locations (Vancouver, Seattle, and Dublin) and a significant number of employees who work remotely, which may create additional opportunities for cybercriminals to exploit vulnerabilities.
We are subject to stringent and changing obligations related to privacy and security. Our actual or perceived failure to comply with such obligations could lead to regulatory investigations or actions, litigation, fines and penalties, disruptions of our business operations, reputational harm and other adverse business consequences.
U.S. states have enacted and are considering enacting laws relating to the protection of personal information (including health and other data of patients, research subjects, and other individuals), which may be more rigorous than, or impose additional requirements beyond those required by, HIPAA. For example, the California Consumer Privacy Act (“CCPA”), which became effective on January 1, 2020, gives California consumers expanded rights to access and delete their personal information, opt out of certain personal information sharing and receive detailed information about how their personal information is used. The CCPA allows for statutory fines for noncompliance (up to $7,500 per violation) as well as a limited private right of action for data breaches, which may increase the volume of data breach litigation. In addition, the California Privacy Rights Act of 2020 (“CPRA”), which went into effect on January 1, 2023, expands the CCPA by, among other things, giving California residents the ability to limit use of certain sensitive personal information, establishing restrictions on personal information retention, expanding the types of data breaches subject to the CCPA’s private right of action, and establishing a new California Privacy Protection Agency to implement and enforce the new law. While limited CCPA exemptions may apply to portions of our business, the recency of the CCPA’s implementing regulations and the California Attorney General’s enforcement activity means obligations under the CCPA, as modified by the CPRA, could evolve in the future, which may increase our compliance costs and potential liability. Many similar privacy and security laws have been proposed at the federal level and in other states, certain of which have been enacted, including such laws in Colorado, Connecticut, Utah and Virginia. These or other proposed or enacted laws relating to privacy and security could similarly increase our compliance obligations and costs in the future.
We may also become subject to laws and regulations in non-U.S. countries covering privacy and security and the protection of health-related and other personal information. In particular, the European Economic Area (“EEA”) has adopted privacy and security protection laws and regulations that impose significant compliance obligations. Laws and regulations in these jurisdictions apply broadly to the collection, use, storage, disclosure, processing and security of information that identifies or may be used to identify an individual, such as names, contact information, and sensitive personal information such as health data. These laws and regulations are subject to frequent revisions and differing interpretations, and have generally become more stringent over time.
The General Data Protection Regulation 2016/679 (“GDPR”) applies to the processing of personal information and imposes many requirements for controllers and processors of personal information, including, for example, higher standards for obtaining consent from individuals to process their personal information, more robust disclosures to individuals and a strengthened individual data rights regime, shortened timelines for data breach notifications, limitations on retention and secondary use of information, increased requirements pertaining to health data and pseudonymized (i.e., key-coded) data and additional obligations when contracting third-party processors in connection with the processing of the personal information. The GDPR allows EEA countries to make additional laws and regulations further limiting the processing of genetic, biometric or health data. Failure to comply with the requirements of the GDPR and the applicable national privacy and security laws of EEA countries may result in fines of up to €20,000,000 or up to 4% of the total worldwide annual turnover of the preceding financial year, whichever is higher, and other administrative penalties; we may also be liable should any individual who has suffered financial or non-financial damage arising from our infringement of the GDPR exercise their right to receive compensation against us. Furthermore, adverse publicity relating to our failure to comply with the GDPR could cause a loss of goodwill, which could have an adverse effect on our reputation, brand, business and financial condition. Additionally, the United Kingdom (“UK”) has implemented legislation similar to the GDPR, referred to as the UK GDPR, which provides for fines of up to the greater of £17.5 million or 4% of global turnover.
Certain jurisdictions, including the EEA, have enacted data localization laws and cross-border personal information transfer laws. For example, absent appropriate safeguards or other circumstances, the GDPR generally restricts the transfer of personal information to countries outside the EEA, such as the United States, which the European Commission does not consider to provide an adequate level of personal information protection. On July 16, 2020, the Court of Justice of the European Union (“CJEU”) invalidated the European Union-U.S. Privacy Shield (“Privacy Shield”) as a data transfer mechanism for transferring personal information from the EEA to the United States. While the EU standard contractual clauses (“EU SCCs”) remain a valid mechanism to transfer personal information to third countries outside the EEA, the CJEU’s ruling has also imposed enhanced due diligence obligations on data exporters and importers to ensure that the laws of the country to which the personal information is transferred offer a level of data protection that is essentially equivalent to the EEA. Also, the EU has issued updated EU SCCs, and the UK has issued its own standard contractual clauses (the “UK SCCs”) that are required to be implemented over time. Although we do not transfer personal data from the EEA to the United States via the Privacy Shield, the CJEU’s decision means that the status of transfers of personal information from the EEA and other regions, including the UK, to the United States is subject to significant regulatory uncertainty. To the extent we transfer personal information from other jurisdictions to the United States, we may not be able to implement or maintain an appropriate data transfer mechanism to continue such international transfers of data. Additionally, the CJEU’s invalidation of the Privacy Shield, the revised EU SCCs and new UK SCCs, regulatory guidance and opinions, and other developments relating to cross-border data transfer may require us to implement additional contractual and technical safeguards for any personal information transferred out of the
EEA, UK, or other regions, which may increase compliance costs, lead to increased regulatory scrutiny or liability, and may require additional contractual negotiations, which may adversely impact our business, financial condition, and operating results.
Separate from, and in addition to, requirements under the GDPR and UK GDPR, certification requirements for the hosting of health data will vary by jurisdiction. To the extent we operate in various EEA countries or the UK, there might be other national healthcare regulations or regulatory requirements with which we will be required to comply. For example, France requires hosts of health data to obtain a prior certification with the competent certification body.
The interpretation and application of consumer, health-related and privacy and security laws in the United States, the EEA, and elsewhere are often uncertain, contradictory and in flux. Any failure or perceived failure to comply with federal, state or foreign laws or regulations, contractual or other legal obligations related to privacy or security may result in claims, warnings, communications, requests or investigations from individuals, supervisory authorities or other legal or regulatory authorities in relation to our processing of personal information, and regulatory investigations or other proceedings. It is possible that these laws may be interpreted and applied in a manner that is inconsistent with our practices. If so, this could result in government-imposed fines or orders requiring that we change our practices, which could adversely affect our business. In addition, these privacy regulations vary between states, may differ from country to country, and may vary based on whether testing is performed in the United States or in the local country. Complying with these various laws could cause us to incur substantial costs or require us to change our business practices and compliance procedures in a manner adverse to our business.
Current and future legislation may increase the difficulty and cost for us to commercialize any products that we or our strategic partners develop and affect the prices we may obtain.
The United States and some foreign jurisdictions are considering or have enacted a number of legislative and regulatory proposals to change healthcare systems in ways that could affect our ability to sell any of our product candidates profitably, if such product candidates are approved for sale. Among policy makers and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and expanding access. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives.
In March 2010, the PPACA became law in the United States. The PPACA may affect the operational results of companies in the pharmaceutical industry, including us, by imposing on them additional costs. For example, effective January 1, 2010, PPACA increased the minimum Medicaid drug rebates for pharmaceutical companies and imposed an annual fee on certain branded prescription drugs and biologics. Since the enactment of PPACA, there have been executive, judicial and Congressional challenges to certain aspects of the PPACA, including judicial challenges in the Fifth Circuit Court and the United States Supreme Court. In June 2021, the United States Supreme Court held that Texas and other challengers had no legal standing to challenge the PPACA, dismissing the case without specifically ruling on the constitutionality of the PPACA. Accordingly, the PPACA remains in effect in its current form. It is unclear how future litigation or healthcare measures promulgated by the Biden administration will impact our business, financial condition and results of operations. Complying with any new legislation or changes in healthcare regulation could be time-intensive and expensive, resulting in a material adverse effect on our business.
Other legislative changes have been proposed and adopted since the PPACA was enacted. For example, the Bipartisan Budget Act of 2018, among other things, amended the PPACA, effective January 1, 2019, to close the coverage gap in most Medicare drug plans. The Budget Control Act of 2011, which calls for aggregate reductions to Medicare payments to providers of up to 2% per fiscal year, began in 2013 and, due to subsequent legislative amendments, will remain in effect through 2031, with the exception of a temporary suspension implemented under various COVID-19 relief legislation from May 1, 2020 through March 31, 2022, unless additional Congressional action is taken. Under current legislation, the actual reduction in Medicare payments will vary from 1% in 2022 to up to 4% in the final fiscal year of this sequester. The American Taxpayer Relief Act of 2012, among other things, further reduced Medicare payments to several providers, including hospitals and cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. These laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect on potential customers for our product candidates, if approved, and, accordingly, our future financial operations. We are unable to predict the future course of federal or state health care legislation or foreign regulations relating to the marketing, pricing and reimbursement of pharmaceutical products.
There have been U.S. Congressional inquiries, presidential executive orders, and proposed federal and state legislation 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. For example, under the American Rescue Plan Act of 2021, effective January 1, 2024, the statutory cap on Medicaid Drug Rebate Program rebates that manufacturers pay to state Medicaid programs will be eliminated. Elimination of this cap may require pharmaceutical manufacturers to pay more in rebates than it receives on the sale of
products, which could have a material impact on our business. Additionally, 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 as well as potential administrative actions HHS can take to advance these principles. As discussed above, Congress passed the Inflation Reduction Act of 2022, which includes prescription drug provisions that have significant implications for the pharmaceutical industry and Medicare beneficiaries, including allowing the federal government to negotiate a maximum fair price for certain high-priced single-source Medicare drugs, imposing penalties and excise tax for manufacturers that fail to comply with the drug price negotiation requirements, requiring inflation rebates for all Medicare Part B and Part D drugs, with limited exceptions, if their drug prices increase faster than inflation, and redesigning Medicare Part D to reduce out-of-pocket prescription drug costs for beneficiaries, among other changes. The implementation of cost containment measures, including the prescription drug provisions under the Inflation Reduction Act, as well as other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our product candidates if approved. Complying with any new legislation and regulatory changes could be time-intensive and expensive, resulting in a material adverse effect on our business.
Further, many states have proposed or enacted legislation that seeks to indirectly or directly regulate pharmaceutical drug pricing, such as by requiring biopharmaceutical manufacturers to publicly report proprietary pricing information or to place a maximum price ceiling on pharmaceutical products purchased by state agencies. For example, a number of states are considering or have enacted state drug price transparency and reporting laws that could substantially increase our compliance burdens and expose us to greater liability under such state laws once we begin commercialization after obtaining regulatory approval for any of our products candidates. We cannot be sure to what extent these and future legislative and regulatory efforts, whether FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals of our product candidates, if any, may be. In addition, increased scrutiny by Congress of the FDA’s approval process may significantly delay or prevent marketing approval, as well as subject us to more stringent product labeling and post-marketing testing and other requirements. These measures could reduce the ultimate demand for our products, once approved, or put pressure on our product pricing. We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could affect the prices we may obtain for any of our product candidates for which we may obtain regulatory approval or the frequency with which any such product candidate, if approved, is prescribed or used.
In the EU similar political, economic and regulatory developments may affect our ability to profitably commercialize any future products. In addition to continuing pressure on prices and cost containment measures, legislative developments at the EU or member state level may result in significant additional requirements or obstacles that may increase our operating costs. In international markets, reimbursement and healthcare payment systems vary significantly by country, and many countries have instituted price ceilings on specific products and therapies. Our future products, if any, might not be considered medically reasonable and necessary for a specific indication or cost-effective by third-party payors, an adequate level of reimbursement might not be available for such products, and third-party payors’ reimbursement policies might adversely affect our or our strategic partners’ ability to sell any future products profitably.
Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities for pharmaceutical products. We cannot be sure whether additional legislative changes will be enacted, or whether the FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals of our product candidates, if any, may be. In addition, increased scrutiny by the U.S. Congress of the FDA’s approval process may significantly delay or prevent marketing approval, as well as subject us to more stringent product labeling and post-approval testing and other requirements.
We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or elsewhere. If we or our strategic partners are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we or our strategic partners are not able to maintain regulatory compliance, our product candidates may lose any marketing approval that may have been obtained and we may not achieve or sustain profitability, which would adversely affect our business.
Unstable or unfavorable global market and economic conditions may have adverse consequences on our business, financial condition and stock price.
Global credit and financial markets have experienced extreme volatility and disruptions in the past several years, including severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates, increases in the rate of inflation and uncertainty about economic stability. We cannot assure you that further deterioration in credit and financial markets and confidence in economic conditions will not occur. Our business, financial condition, and stock price may be adversely affected by any such economic downturn, volatile business environment,
or large-scale unpredictable or unstable market conditions, including a prolonged government shutdown, geopolitical events such as the conflict between Russia and Ukraine, or a global pandemic such as the COVID-19 pandemic.
If the current equity and credit markets deteriorate, it may make any necessary debt or equity financing more difficult, more costly and more dilutive. 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 development plans. In addition, there is a risk that one or more of our current service providers, manufacturers and other partners may not survive difficult economic times, which could directly affect our ability to attain our operating goals on schedule and on budget.
Our business may become subject to economic, political, regulatory and other risks associated with international operations.
Our business is subject to risks associated with conducting business internationally. We have physical operations and personnel in Canada, the United States, and Ireland, and maintain offices in these three countries. We have recently established a subsidiary in Singapore, and intend to hire personnel and establish an office there. In addition, some of our suppliers and collaborative and clinical trial relationships are located outside the United States. Accordingly, our future results could be harmed by a variety of factors, including:
•economic instability or weakness, including inflation, reduced growth, diminished credit availability, weakened consumer confidence or increased unemployment;
•instability in the international geopolitical environment, including as a result of the Russian invasion of Ukraine;
•sociopolitical instability in particular foreign economies and markets;
•differing regulatory requirements for drug approvals in foreign countries;
•potentially reduced protection for intellectual property rights;
•difficulties in compliance with non-U.S. laws and regulations;
•changes in non-U.S. regulations and customs, tariffs and trade barriers, including any changes that China may impose as a result of political tensions between Canada and China or the United States and China;
•regulatory changes and economic conditions following the UK’s withdrawal from the EU and uncertainty related to the terms of the withdrawal;
•changes in non-U.S. currency exchange rates and currency controls;
•trade protection measures, import or export licensing requirements or other restrictive actions by U.S. or non-U.S. governments;
•differing reimbursement regimes, including price controls;
•negative consequences from changes in tax laws;
•workforce uncertainty in countries where labor unrest is more common than in the United States;
•production shortages resulting from any events affecting raw material supply or manufacturing capabilities outside the United States;
•business interruptions resulting from geopolitical actions, including war and terrorism, or natural disasters including earthquakes, typhoons, floods and fires; and
•supply and other disruptions resulting from the impact of public health epidemics, including the COVID-19 pandemic, on our strategic partners, third-party manufacturers, suppliers and other third parties upon which we rely.
Our business has been and may continue to be adversely affected by the COVID-19 pandemic.
The COVID-19 pandemic has had a broad adverse impact on the global economy across many industries and has resulted in significant governmental measures being implemented to control the spread of the virus, including quarantines, travel restrictions and business shutdowns, as well as significant volatility in global financial markets. Recently, President Biden announced that the administration intends to end the COVID-19 national and public health emergencies on May 11, 2023. The full impact of this termination of the public health emergencies on the FDA and other regulatory policies and operations are unclear.
Certain clinical trial activities, including patient enrollment and site activations, may be delayed or otherwise impacted by COVID-19 or another pandemic or epidemic, or emergence of other infectious diseases. Although we do not currently anticipate any further material impacts to our business from COVID-19 or another pandemic or epidemic, these and similar, and perhaps more severe, disruptions in our operations could negatively impact our business and financial condition in the future, but the extent of such impact will depend on future developments, which are highly uncertain and cannot be predicted, such as the location, duration and severity of outbreaks (including future potential waves or cycles), travel restrictions and social distancing, business closures or disruptions, and the effectiveness of actions taken to contain and treat the disease and to address its impact, including on financial markets.
If a resurgence of COVID-19, the emergence of another pandemic or epidemic, or the emergence of other infectious diseases were to occur, a lack of coordinated response on risk mitigation and global vaccination deployment could result in significant increases to the duration and severity of such event and could have a corresponding negative impact on our business. For example, insufficient vaccine availability, reduced effectiveness of vaccines over time or against new variants, or resistance to vaccination by certain persons may result in increasing infection and hospitalization rates, which have been and could be further complicated by the emergence of more virulent or infectious variants of the virus or other diseases.
If the COVID-19 pandemic, another pandemic or epidemic, or other infectious diseases surge, worsen or continue for a prolonged period of time, particularly in regions where we or our strategic partners and suppliers do business, we could experience disruptions that could significantly impact our current and planned clinical trials, preclinical research and other business activities, including:
•disruption to and delays in preclinical research activities due to extended closure or reduced capacity of lab facilities;
•further delays or difficulties in enrolling patients in our ongoing and planned clinical trials;
•patients discontinuing their treatment or follow-up visits;
•further delays or difficulties in clinical site initiation, including limitations on access to sites, limitations to site initiation activities that can be carried out remotely, and limitations on the number of clinical site staff on site from time to time;
•interruption of key clinical trial activities, such as clinical trial site monitoring, due to limitations on travel imposed or recommended by federal or state governments, employers and others;
•shortages, disruptions in supply, logistics or other activities related to the procurement of materials and other supplies, which could have a negative impact on our ability to conduct preclinical research, initiate or complete our clinical trials or commercialize our product candidates;
•diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites and hospital staff supporting the conduct of clinical trials;
•interruption of key business activities due to illness and/or quarantine of key individuals and delays associated with recruiting, hiring and training new temporary or permanent replacements for such key individuals, both internally and at our third-party service providers and strategic partners;
•limitations in resources that would otherwise be focused on the conduct of our business or our current or planned clinical trials or preclinical research, including because of sickness, the desire to avoid contact with large groups of people, restrictions on travel, or prolonged stay-at-home or similar working arrangements;
•delays in receiving approvals from regulatory authorities to initiate our planned clinical trials;
•changes in regulations as part of a response to the COVID-19 pandemic, another pandemic or epidemic, or other infectious diseases, which may require us to change the ways in which our clinical trials are conducted and incur unexpected costs, or require us to discontinue clinical trials altogether;
•delays in necessary interactions with regulators (including the FDA), ethics committees and other important agencies and contractors due to limitations in employee resources or furlough of government or contractor personnel;
•disruptions to our strategic partners’ operations, which could delay the development of our product candidates in certain geographical regions and thereby affect the timing of development and commercial milestone payments and royalties on potential future product sales we may receive; and
•limitations on our ability to recruit any necessary preclinical research, clinical, regulatory and other professional staff on the timeframe required to support our research and development programs.
In addition, COVID-19, another pandemic or epidemic, or other infectious diseases could disrupt the global financial markets, reducing our ability to access capital, which could negatively affect our liquidity. If a resurgence of COVID-19, the emergence of another pandemic or epidemic, or the emergence of other infectious diseases were to occur, the volatility of the financial market may be heightened, which could adversely impact the value of our common stock.
Our business and current and future relationships with customers and third-party payors in the United States and elsewhere will be subject, directly or indirectly, to applicable federal and state anti-kickback, fraud and abuse, false claims, transparency, health information privacy and security, and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm, administrative burdens, and diminished profits and future earnings.
Healthcare providers, physicians and third-party payors in the United States and elsewhere play a primary role in the recommendation and prescription of any product candidates for which we obtain marketing approval.
Our current and future arrangements with healthcare professionals, principal investigators, consultants, customers, and third-party payors and other entities may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations, including the federal Anti-Kickback Statute and the federal False Claims Act, that may constrain the business or financial arrangements and relationships through which we conduct clinical research on product candidates and market, sell and distribute any products for which we obtain marketing approval. In addition, we may be subject to transparency laws and patient privacy regulation by the federal government and by the U.S. states and foreign jurisdictions in which we conduct our business. The applicable federal, state and foreign healthcare laws and regulations that may affect our ability to operate include the following:
•the federal Anti-Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting, offering, receiving or providing remuneration (including any kickback, bribe or rebate), directly or indirectly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, order or recommendation of, any good or service for which payment may be made under federal and state healthcare programs such as Medicare and Medicaid;
•federal civil and criminal false claims laws and civil monetary penalty laws, including the federal False Claims Act, impose criminal or civil penalties, as applicable, against individuals or entities for knowingly presenting, or causing to be presented, to the federal government (including the Medicare and Medicaid programs) or other third-party payor claims for payment that are false or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay money to the federal government;
•HIPAA established the federal offense of health care fraud, which among other things, imposes criminal liability for knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program or to obtain, by means of false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit program, regardless of the payor (e.g. public or private) and knowingly and willfully falsifying, concealing or covering up by any trick or device a material fact or making any materially false statements in connection with the delivery of or payment for healthcare benefits, items or services relating to healthcare matters;
•HIPAA, as amended by HITECH, and its implementing regulations, which imposes certain obligations, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of individually identifiable health information without the appropriate authorization by entities subject to the law, such as health plans, healthcare clearinghouses and healthcare providers and their respective business associates and their covered subcontractors;
•the federal Open Payments program under the Physician Payments Sunshine Act, created under Section 6002 of the PPACA and its implementing regulations, requires applicable group purchasing organizations and manufacturers of 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 HHS information related to “payments or other transfers of value” made in the previous year to covered recipients, including physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors, other health care professionals (such as nurse practitioners and physician assistants) and teaching hospitals, and information regarding ownership and investment interests held by physicians (as defined above) or their immediate family members; and
•analogous and similar state and foreign laws and regulations, including: state anti-kickback and false claims laws that may apply to our business practices (including research, distribution, sales and marketing arrangements and claims involving healthcare items or services reimbursed by state governmental and non-governmental third-party payors,
including private insurers); state laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the applicable compliance guidance promulgated by the federal government; state laws that require drug manufacturers to track gifts and other remuneration and items of value provided to healthcare professionals and entities and file reports relating to pricing and marketing information; and state and foreign laws that govern the privacy and security of health information in specified circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.
Because of the breadth of these laws and the narrowness of any available statutory exceptions and safe harbors, it is possible that some of our current and future business activities could be subject to challenge under one or more of such laws.
Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations may involve substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. Any failure or perceived failure by us to comply with such laws, regulations, or case law may result in governmental investigations or enforcement actions, litigation, claims and other proceedings, harm our reputation, and could result in significant liability. Additionally, if our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, including damages, fines, imprisonment, exclusion from participation in government healthcare 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 noncompliance with these laws and the curtailment or restructuring of our operations, which could have a material adverse effect on our business. If any of the physicians or other providers or entities with whom we expect to do business, including our strategic partners, is found not to be in compliance with applicable laws, it may be subject to criminal, civil or administrative sanctions, including exclusions from participation in government healthcare programs, which could also materially affect our business.
We are subject to U.S. and certain foreign export and import controls, sanctions, embargoes, anti-corruption laws, and anti-money laundering laws and regulations. Compliance with these legal standards could impair our ability to compete in domestic and international markets. We can face criminal liability and other serious consequences for violations that can harm our business.
We are subject to export control and import laws and regulations, including the U.S. Export Administration Regulations, U.S. Customs regulations, various economic and trade sanctions regulations administered by the U.S. Treasury Department’s Office of Foreign Assets Controls, the U.S. Foreign Corrupt Practices Act of 1977, as amended, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the USA PATRIOT Act, the United Kingdom Bribery Act 2010, the Proceeds of Crime Act 2002, and other state and national anti-bribery and anti-money laundering laws in the countries in which we conduct activities. Anti-corruption laws are interpreted broadly and prohibit companies and their employees, agents, contractors, and other partners from authorizing, promising, offering, or providing, directly or indirectly, improper payments or anything else of value to recipients in the public or private sector. We currently engage third parties for clinical trials outside of the United States and we may in the future engage third parties to sell our products outside of the United States once we enter a commercialization phase, or to obtain necessary permits, licenses, patent registrations, and other regulatory approvals. We may have direct or indirect interactions with officials and employees of government agencies or government-affiliated hospitals, universities, and other organizations. We can be held liable for the corrupt or other illegal activities of our employees, agents, contractors, and other partners, even if we do not explicitly authorize or have actual knowledge of such activities. Any violation of the laws and regulations described above may result in substantial civil and criminal fines and penalties, imprisonment, the loss of export or import privileges, debarment, tax reassessments, breach of contract and fraud litigation, reputational harm, and other consequences.
Third-party manufacturers may not be able to comply with U.S. export control regulations, cGMP regulations or similar regulatory requirements outside the United States. Our failure, or the failure of our third-party manufacturers, to comply with applicable regulations could result in a necessity to replace current third parties, resulting in the possibility of supply delays, clinical holds on our trials, sanctions being imposed on us, including fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, license revocations, seizures or recalls of product candidates or medicines, operating restrictions, and criminal prosecutions, any of which could significantly and adversely affect supplies of our medicines and harm our business, financial condition, results of operations and growth prospects.
We have received an unsolicited, non-binding proposal from an existing investor to purchase our Company.
In April 2022, All Blue Falcons FZE (“All Blue Falcons”), an existing stockholder, submitted an unsolicited, non-binding proposal to purchase our Company for $10.50 per share in cash. Our board of directors carefully reviewed the proposal and, in May 2022, unanimously determined that the unsolicited, non-binding proposal substantially undervalued our Company and was not in the best interest of the Company and its stockholders. While All Blue Falcons has not submitted a follow-up proposal and we have not had subsequent engagement with All Blue Falcons following our rejection of the non-binding proposal, reviewing this matter has in the past and may in the future divert management’s and our board of directors’ attention and has and may require us to incur significant costs related to our engagement of advisors. Any further actions by All Blue Falcons or others may disrupt our business and operations by causing uncertainty among and potentially loss of current and prospective employees, partners, suppliers and other constituencies important to our success or delay certain initiatives, transactions or the like that we are pursuing. Any of the foregoing could materially and negatively impact our business and financial results. The price of our common stock could be subject to price fluctuations due to the uncertainty associated with any such matter.
Risks Related to Our Financial Position and Need for Additional Capital
We have incurred significant losses since inception and anticipate that we will continue to incur losses for the foreseeable future. We have no products approved for commercial sale, and to date we have not generated any revenue or profit from product sales. We may never achieve or sustain profitability.
We are a clinical-stage biopharmaceutical company. We have incurred significant losses since our inception. Our net income for the year ended December 31, 2022 was $124.3 million, while our net loss for the years ended December 31, 2021 and 2020 was $211.8 million and $180.6 million, respectively. As of December 31, 2022, our accumulated deficit was $558.8 million. We expect to continue to incur losses for the foreseeable future as we continue our research and development of, and seek regulatory approvals for, our product candidates, prepare for and begin to commercialize any approved product candidates and add infrastructure, which may include personnel, to support our product development efforts. In addition, inflationary pressure could adversely impact our financial results. The net losses and negative cash flows incurred to date, together with expected future losses, have had, and likely will continue to have, an adverse effect on our stockholders’ deficit and working capital. The amount of future net losses will depend, in part, on the rate of future growth of our expenses and our ability to generate revenue.
Because of the numerous risks and uncertainties associated with pharmaceutical product development, we are unable to accurately predict the timing or amount of increased expenses or when, or if, we will be able to achieve profitability.
To become and remain profitable, we must succeed in developing and commercializing product candidates with significant market potential. This will require us to be successful in a range of challenging activities for which we are only in the preliminary stages, including developing product candidates, obtaining regulatory approval for such product candidates, and manufacturing, marketing and selling those product candidates for which we may obtain regulatory approval. We may never succeed in these activities and may never generate revenue from product sales that is significant enough to achieve profitability. Even if we achieve profitability in the future, we may not be able to sustain profitability in subsequent periods. Our failure to become or remain profitable would depress our market value and could impair our ability to raise capital, expand our business, develop other product candidates, or continue our operations. A decline in the value of our company could also cause our stockholders to lose all or part of their investment.
Biopharmaceutical product development is a highly speculative undertaking and involves a substantial degree of uncertainty. We have never generated any revenue from product sales and may never be profitable.
We have devoted substantially all of our financial resources and efforts to developing our proprietary therapeutic platforms, identifying potential product candidates and conducting preclinical studies and clinical trials. We and our partners are still developing our product candidates, and we have not completed development of any products. Our revenue to date has been primarily revenue from the license of our proprietary therapeutic platforms for the development of product candidates by others or revenue from our strategic partners. Our ability to generate revenue and achieve profitability depends in large part on our ability, alone or with our strategic partners, to achieve milestones and to successfully complete the development of, obtain the necessary regulatory approvals for, and commercialize, product candidates. We do not anticipate generating revenue from sales of products in the near term.
We will require substantial additional funding, which may not be available to us on acceptable terms, or at all, and, if not available, may require us to delay, scale back, or cease our product development programs or operations.
We are currently advancing two of our product candidates through clinical development as well as other potential product candidates through discovery and preclinical development. Developing pharmaceutical products, including conducting preclinical studies and clinical trials, is expensive. In order to obtain regulatory approval, we will be required to conduct clinical trials for each indication for each of our product candidates. Although our collaboration agreements with Jazz and BeiGene provide for the future funding requirements for our lead asset, zanidatamab, we will continue to require additional funding to complete the development and commercialization of zanidatamab zovodotin, and to continue to advance the development of our other product candidates, and such funding may not be available on acceptable terms or at all. If sufficient funds on acceptable terms are not available when needed, or at all, we could be forced to significantly reduce operating expenses and delay, scale back or eliminate one or more of our development programs or our business operations. For example, in January 2022, we began implementing a Company-wide reduction in workforce to help achieve a more cost-efficient organization, which we believe will enhance our ability to execute on our key priorities. While we completed the reduction in workforce by the end of 2022, the full impact of the reduction in workforce is not yet known.
Our future funding requirements will depend on many factors, including:
•the number and characteristics of other product candidates that we pursue;
•the scope, progress, timing, cost and results of research, preclinical development, and clinical trials;
•the costs, timing and outcome of seeking and obtaining FDA and non-U.S. regulatory approvals;
•the costs associated with manufacturing our product candidates and establishing sales, marketing and distribution capabilities;
•our ability to maintain, expand and defend the scope of our intellectual property portfolio, including the amount and timing of any payments we may be required to make in connection with the licensing, filing, defense and enforcement of any patents or other intellectual property rights;
•our ability to achieve the anticipated cost reductions from the reduction in workforce implemented in 2022;
•our ability to hire when needed additional management, scientific and medical personnel;
•the effect of competing products that may limit market penetration of our product candidates;
•our need to implement additional internal systems and infrastructure, including financial and reporting systems; and
•the economic and other terms, timing of and success of our existing strategic partnerships, and any collaboration, asset monetization, licensing, or other arrangements into which we may enter in the future, including the timing of receipt of any milestone or royalty payments under these agreements.
Until we can generate a sufficient amount of product revenue to finance our cash requirements, which we may never do, we expect to finance future cash needs primarily through a combination of public and private equity offerings, debt financings, asset monetization, strategic partnerships and grant funding.
Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish substantial rights.
To the extent that we raise additional capital through the sale of equity or convertible debt securities, our stockholders’ ownership interest will be diluted, and the terms of these new securities may include liquidation or other preferences that adversely affect our stockholders’ rights as common stockholders. Debt financing, if available at all, may involve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures, or declaring dividends. If we raise additional funds through partnerships, collaborations, strategic alliances, or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, product candidates, or future revenue streams, or grant licenses on terms that are not favorable to us. We cannot assure that we will be able to obtain additional funding if and when necessary. If we are unable to obtain adequate financing on a timely basis, we could be required to delay, scale back or eliminate one or more of our development programs or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.
Risks Related to Our Dependence on Third Parties
We will depend on our collaborative relationship with Jazz to further develop and commercialize zanidatamab, and if our relationship is not successful or is terminated, we may be delayed in or unable to effectively develop and/or commercialize zanidatamab, which could have a material adverse effect on our business.
In October 2022, Zymeworks BC entered into the Jazz Collaboration Agreement with Jazz. Pursuant to the terms of the agreement, we received a $50 million upfront payment following receipt of HSR Clearance and delivery of licenses and technology transfer to Jazz and a further payment of $325 million following Jazz’s decision to continue the collaboration after readout of the top-line clinical data from HERIZON-BTC-01. We are also eligible to receive additional milestone payments upon achievement of certain regulatory and commercial milestones, as well as tiered royalties on Jazz’s net sales of licensed products. We will depend on Jazz to collaborate with us to develop and commercialize zanidatamab in the territories covered by the Jazz Collaboration Agreement and, as a result, the eventual success or commercial viability of zanidatamab is largely beyond our control. Following receipt of the initial payments totaling $375 million, any future financial returns to us depend in large part on achievement of regulatory and commercialization milestones, plus a share of any revenue from sales. Therefore, our success, and any associated financial returns to us and our investors, will depend in significant part on Jazz’s performance under the Jazz Collaboration Agreement.
We are subject to a number of additional specific risks associated with our dependence on our collaborative relationship with Jazz, including:
•adverse decisions by Jazz regarding the development and commercialization of zanidatamab;
•possible disagreements as to the timing, nature and extent of development plans, including clinical trials or regulatory approval strategy;
•loss of significant rights if we fail to meet our obligations under the agreement;
•changes in key management personnel at Jazz; and
•possible disagreements with Jazz regarding the agreement, for example, with regard to ownership of intellectual property rights.
If either we or Jazz fail to perform our respective obligations, any clinical trial, regulatory approval or development progress could be significantly delayed or halted, could result in costly or time-consuming litigation or arbitration and could have a material adverse effect on our business.
Decisions by Jazz to emphasize other drug candidates currently in its portfolio ahead of zanidatamab, or to add competitive agents to its portfolio could result in a decision to terminate the agreement, in which event, among other things, we may be responsible for paying any remaining costs of ongoing or future clinical trials. If Jazz decides to terminate the Jazz Collaboration Agreement, we may be delayed in or unable to effectively develop and/or commercialize zanidatamab, which could have a material adverse effect on our business.
Any of the above discussed scenarios could adversely affect the timing and extent of the development and commercialization activities related to zanidatamab, which could materially and adversely impact our business.
Our existing strategic partnerships are important to our business, and future strategic partnerships will likely also be important to us. If we are unable to maintain our strategic partnerships, or if these strategic partnerships are not successful, our business could be adversely affected.
We have limited capabilities for drug development and commercialization of our product candidates, if approved. Accordingly, we have entered into strategic partnerships with other companies that we believe can provide such capabilities, including our collaboration and license agreements with Jazz, BeiGene, BMS, GSK, Daiichi Sankyo, Janssen, LEO, Iconic, Merck and Atreca. These relationships also have provided us with non-dilutive funding for our wholly owned pipeline and therapeutic platforms and we expect to receive additional funding under these strategic partnerships in the future. Our existing strategic partnerships, and any future strategic partnerships we enter into, may pose a number of risks, including the following:
•strategic partners have significant discretion in determining the efforts and resources that they will apply to these partnerships;
•strategic partners may not perform their obligations as expected;
•strategic partners may not pursue development and commercialization of any product candidates that achieve regulatory approval or may elect not to continue or renew development or commercialization programs based on clinical trial results, changes in the partners’ strategic focus or available funding, or external factors, such as an acquisition, that divert resources or create competing priorities;
•strategic partners may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial or abandon a product candidate, repeat or conduct new clinical trials or require a new formulation of a product candidate for clinical testing;
•strategic partners could independently develop, or develop with third parties, products that compete directly or indirectly with our product candidates if the strategic partners believe that competitive products are more likely to be successfully developed or can be commercialized under terms that are more economically attractive than our product candidates;
•product candidates discovered in collaboration with us may be viewed by our strategic partners as competitive with their own product candidates or products, which may cause strategic partners to cease to devote resources to the commercialization of our product candidates;
•a strategic partner with marketing and distribution rights to one or more of our product candidates that achieve regulatory approval may not commit sufficient resources to the marketing and distribution of such product candidates;
•disagreements with strategic partners, including disagreements over proprietary rights, contract interpretation or the preferred course of development, might cause delays or termination of the research, development or commercialization of product candidates, might lead to additional responsibilities for us with respect to product candidates, or might result in litigation or arbitration, any of which would be time-consuming and expensive;
•strategic partners may not properly maintain or defend our intellectual property rights or may use our proprietary information in such a way as to invite litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us to potential litigation;
•strategic partners may infringe the intellectual property rights of third parties, which may expose us to litigation and potential liability;
•strategic partnerships may be terminated for the convenience of the partner and, if terminated, we could be required to raise additional capital to pursue further development or commercialization of the applicable product candidates. For example, each of our collaboration and license agreements with Jazz, BeiGene, BMS, GSK, Daiichi Sankyo, Janssen, LEO, Iconic, Merck and Atreca may be terminated for convenience upon the completion of a specified notice period;
•we may elect to enter into additional licensing or collaboration agreements to partner our product candidates in territories we currently retain, and in the event we grant exclusive rights to such partners, we would be precluded from potential commercialization of our product candidates within the territories in which we have a partner; and
•strategic partners may not have the ability or the development capabilities to perform their obligations as expected, including as a result of the impact of the COVID-19 pandemic or the emergence of another pandemic or epidemic on our strategic partners’ operations or business.
If our strategic partnerships do not result in the successful development and commercialization of product candidates or if one of our partners terminates its agreement with us, we may not receive any future research funding or milestone or royalty payments under the collaboration. If we do not receive the funding we expect under our strategic partnership agreements, our development of our therapeutic platforms and product candidates could be delayed and we may need additional resources to develop product candidates and our therapeutic platforms.
We face significant competition in seeking new strategic partners.
For some of our product candidates, we may in the future determine to collaborate with additional pharmaceutical and biotechnology companies for development and potential commercialization of therapeutic products. Our ability to reach a definitive agreement for a collaboration will depend, among other things, upon our assessment of the strategic partner’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed strategic partner’s evaluation of a number of factors. These factors may include the design or results of clinical trials, the likelihood of approval by the FDA or similar regulatory authorities outside the United States, the potential market for the subject product candidate, the costs and complexities of manufacturing and delivering such product candidate to patients, the potential of competing products, the existence of uncertainty with respect to our ownership of technology, which can exist if there is a challenge to such ownership without regard to the merits of the challenge, and industry and market conditions generally. The strategic partner may also
consider alternative product candidates or technologies for similar indications that may be available to collaborate on and whether such a collaboration could be more attractive than the one with us for our product candidate.
Strategic partnerships are complex and time-consuming to negotiate and document. In addition, there have been a significant number of recent business combinations among large pharmaceutical companies that have resulted in a reduced number of potential future strategic partners. If we are unable to reach agreements with suitable strategic partners on a timely basis, on acceptable terms, or at all, we may have to curtail the development of a product candidate, reduce or delay one or more of our other development programs, delay potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to fund and undertake development or commercialization activities on our own, we may need to obtain additional expertise and additional capital, which may not be available to us on acceptable terms or at all. If we fail to enter into strategic partnerships and do not have sufficient funds or expertise to undertake the necessary development and commercialization activities, we may not be able to further develop our product candidates or bring them to market or continue to develop our therapeutic platforms and our business may be materially and adversely affected.
We rely on third-party manufacturers to produce our product candidates and on other third parties to provide supplies and store, monitor and transport bulk drug substance and drug product. We and our third-party partners may encounter difficulties with respect to these activities that could delay or impair our ability to initiate or complete our clinical trials or commercialize approved products.
We do not currently own or operate any manufacturing facilities. We rely on our strategic partners to manufacture product candidates licensed to them or work with multiple third-party contract manufacturers to produce sufficient quantities of materials required for the manufacture of our product candidates for preclinical testing and clinical trials, in compliance with applicable regulatory and quality standards, and intend to do so for the commercial manufacture of our products. If we are unable to arrange for such third-party manufacturing sources, or fail to do so on commercially reasonable terms, we may not be able to successfully produce sufficient supply of product candidate or we may be delayed in doing so. Such failure or substantial delay could materially harm our business.
The manufacture of biopharmaceutical products is complex and requires significant expertise and capital investment, including the development of advanced manufacturing techniques and process controls. The process of manufacturing our product candidates is susceptible to product loss due to contamination, equipment failure or improper installation or operation of equipment, vendor or operator error, inconsistency in yields, variability in product characteristics and difficulties in scaling the production process. Even minor deviations from normal manufacturing processes could result in reduced production yields, product defects and other supply disruptions. If microbial, viral or other contaminations are discovered in our product candidates or in the third-party manufacturing facilities in which our product candidates are made, such manufacturing facilities may need to be closed for an extended period of time to investigate and remedy the contamination. All of our engineered antibodies are manufactured by utilizing cells that are stored in a cell bank. We have one master cell bank and one working cell bank utilized for each antibody manufactured in accordance with cGMP. While we believe we would have adequate back up at a secondary storage location, should any cell bank be lost in a catastrophic event, it is possible that we could lose part of a cell bank and have our manufacturing potentially impacted by the need to replace the cell bank. Any adverse developments affecting manufacturing operations for our product candidates, if any are approved, may result in shipment delays, inventory shortages, lot failures, product withdrawals or recalls, or other interruptions in the supply of our products. We may also have to take inventory write-offs and incur other charges and expenses for products that fail to meet specifications, undertake costly remediation efforts or seek more costly manufacturing alternatives.
Furthermore, reliance on third-party manufacturers entails risks to which we would not be subject if we manufactured product candidates ourselves, including reliance on the third party for regulatory compliance and quality control and assurance, volume production, the possibility of breach of the manufacturing agreement by the third party because of factors beyond our control (including a failure to manufacture our product candidates in accordance with our product specifications) and the possibility of termination or nonrenewal of the agreement by the third party at a time that is costly or damaging to us. In addition, the FDA, EMA and other regulatory authorities require that our product candidates be manufactured according to cGMP and similar foreign standards. Pharmaceutical manufacturers and their subcontractors are required to register their facilities or products manufactured at the time of submission of the marketing application and then annually thereafter with the FDA and certain state and foreign agencies. They are also subject to periodic unannounced inspections by the FDA, state and other foreign authorities. Any subsequent discovery of problems with a product, or a manufacturing or laboratory facility used by us or our strategic partners, may result in restrictions on the product or on the manufacturing or laboratory facility, including marketed product recall, suspension of manufacturing, product seizure, or a voluntary withdrawal of the drug from the market. We may have little to no control regarding the occurrence of third-party manufacturer incidents. Any failure by our third-party manufacturers to comply with cGMP or failure to scale up manufacturing processes, including any failure to deliver sufficient quantities of
product candidates in a timely manner, could lead to a delay in, or failure to obtain, regulatory approval of any of our product candidates.
In addition to third-party manufacturers, we rely on other third parties to store, monitor and transport bulk drug substance and drug product. If we are unable to arrange for such third-party sources, or fail to do so on commercially reasonable terms, we may not be able to successfully supply sufficient product candidate or we may be delayed in doing so. Such failure or substantial delay could materially harm our business.
In addition, disruptions to ports and other shipping infrastructure, as were experienced during the COVID-19 pandemic, may result in shortages or delays impacting the availability of materials and other supplies, which could negatively impact our manufacturers, suppliers and other third parties on whom we rely. While we have not yet suffered any direct, material negative impacts from these ongoing supply chain disruptions, we cannot be certain that we will not be impacted, which could increase our costs or negatively impact our development timelines.
We rely on third parties to monitor, support, conduct and oversee clinical trials of the product candidates that we are developing and, in some cases, to maintain regulatory files for those product candidates. We may not be able to obtain regulatory approval for our product candidates or commercialize any products that may result from our development efforts if we are not able to maintain or secure agreements with such third parties on acceptable terms, if these third parties do not perform their services as required, or if these third parties fail to timely transfer any regulatory information held by them to us.
We rely on entities outside of our control, which may include academic institutions, CROs, hospitals, clinics and other third-party strategic partners, to monitor, support, conduct and oversee preclinical studies and clinical trials of our current and future product candidates. We also rely on third parties to perform clinical trials on our current and future product candidates when they reach that stage. As a result, we have less control over the timing and cost of these studies and the ability to recruit trial subjects than if we conducted these trials with our own personnel.
If we are unable to maintain or enter into agreements with these third parties on acceptable terms, or if any such engagement is terminated prematurely, we may be unable to enroll patients on a timely basis or otherwise conduct our trials in the manner we anticipate. In addition, there is no guarantee that these third parties will devote adequate time and resources to our studies or perform as required by our contract or in accordance with regulatory requirements, including maintenance of clinical trial information regarding our product candidates. These third parties, in turn, may face their own constraints in obtaining the resources and personnel needed to perform the work for which we engage them. If these third parties fail to meet expected deadlines, fail to transfer to us any regulatory information in a timely manner, fail to adhere to protocols or fail to act in accordance with regulatory requirements or our agreements with them, or if they otherwise perform in a substandard manner or in a way that compromises the quality or accuracy of their activities or the data they obtain, then clinical trials of our product candidates may be extended or delayed with additional costs incurred, or our data may be rejected by the FDA, EMA or other regulatory agencies.
Ultimately, we are responsible for ensuring that each of our clinical trials is conducted in accordance with the applicable protocol, legal, regulatory and scientific standards, and our reliance on third parties does not relieve us of our regulatory responsibilities.
We and our CROs are required to comply with GCP regulations and guidelines enforced by the FDA, the competent authorities of the member states of the EU and comparable foreign regulatory authorities for products in clinical development. Regulatory authorities enforce these GCP regulations through periodic inspections of clinical trial sponsors, principal investigators and clinical trial sites. If we or any of our CROs fail to comply with applicable GCP regulations, the clinical data generated in our clinical trials may be deemed unreliable and our submission of marketing applications may be delayed or the FDA may require us to perform additional clinical trials before approving our marketing applications. Upon inspection, the FDA could determine that any of our clinical trials fail or have failed to comply with applicable GCP regulations. In addition, our clinical trials must be conducted with product produced under the cGMP regulations enforced by the FDA, and our clinical trials may require a large number of test subjects. Our failure to comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process and increase our costs. Moreover, our business may be implicated if any of our CROs violates federal or state fraud and abuse or false claims laws and regulations or healthcare privacy and security laws.
If any of our clinical trial sites terminate for any reason, we may experience the loss of follow-up information on patients enrolled in our ongoing clinical trials unless we are able to transfer the care of those patients to another qualified clinical trial
site. Further, if our relationship with any of our CROs is terminated, we may be unable to enter into arrangements with alternative CROs on commercially reasonable terms, or at all.
Switching or adding CROs or other suppliers can involve substantial cost and require extensive management time and focus. In addition, there is a natural transition period when a new CRO or supplier commences work. As a result, delays may occur, which can materially impact our ability to meet our desired clinical development timelines. If we are required to seek alternative supply arrangements, the resulting delays and potential inability to find a suitable replacement could materially and adversely impact our business.
We rely on third parties for various operational and administrative aspects of our business, including for certain cloud-based software platforms, which impact our financial, operational and research activities. If any of these third parties fail to provide timely, accurate and ongoing service or if the cloud-based platforms suffer outages that we are unable to mitigate, our business may be adversely affected.
We currently rely upon third-party consultants and contractors to provide certain operational and administrative services, including external financial, legal, clinical and research consultation. The failure of any of these third parties to provide accurate and timely service may adversely impact our business operations. In addition, if such third-party service providers were to cease operations, temporarily or permanently, face financial distress or other business disruption, or increase their fees, or if our relationships with these providers deteriorate, we could suffer increased costs until an equivalent provider could be found, if at all, or we could develop internal capabilities, if ever.
In addition, if we are unsuccessful in choosing or finding high-quality partners, if we fail to negotiate cost-effective relationships with them, or if we ineffectively manage these relationships, it could have an adverse impact on our business and financial performance.
Further, our operations depend on the continuing and efficient operation of our information technology and communications systems and infrastructure, and specifically on “cloud-based” platforms. These platforms are vulnerable to damage or interruption from earthquakes, vandalism, sabotage, terrorist attacks, floods, fires, power outages, telecommunications failures, and computer viruses or other deliberate attempts to harm the systems. The occurrence of a natural or intentional disaster, any decision to close a facility we are using without adequate notice, or particularly an unanticipated problem at our cloud-based virtual server facility, could result in harmful interruptions in our service, resulting in adverse effects to our business.
Risks Related to Our Intellectual Property
Our commercial success depends significantly on our ability to operate without infringing the patents and other proprietary rights of third parties.
Our success will depend in part on our ability to operate without infringing the proprietary rights of third parties. Other entities may have or obtain patents or proprietary rights that could limit our ability to make, use, sell, offer for sale or import our future approved products or impair our competitive position. For example, certain patents and patent applications held by third parties cover Fab and Fc region engineering methods for bispecific antibodies, and antibodies having mutations in Fab heavy and light chain regions and Fc regions to generate correctly paired bispecific antibodies. If our products or our strategic partners’ products incorporate any Fab or Fc region mutations covered by any claims of these patents or patents that may issue from these applications, and if licenses for them are not available on commercially reasonable terms or at all, and we are unable to invalidate or render unenforceable those patents, our business could be materially harmed.
We are also aware of third-party patents and patent applications containing claims directed to compositions and methods for treating various forms of cancer with antibodies targeting HER2, alone or in combination with other anti-cancer agents, which patents and applications could potentially be construed to cover our product candidates and the use thereof to treat cancer. If our products or our strategic partners’ products were found to infringe any such patents, and if licenses for them are not available on commercially reasonable terms, or at all, and we were unable to invalidate or render unenforceable those patents, our business could be materially harmed. These patents may not expire before we receive marketing authorization for our product candidates, and could delay the commercial launch of one or more future products. There is also no assurance that there are not third-party patents or patent applications of which we are aware, but which we do not believe are relevant to our business, which may, nonetheless, ultimately be found to limit our ability to make, use, sell, offer for sale or import our future approved products or impair our competitive position.
Patents that we may ultimately be found to infringe could be issued to third parties. Third parties may have or obtain valid and enforceable patents or proprietary rights that could block us from developing product candidates using our technology. Our failure to obtain a license to any patent covering any technology that we require may materially harm our business, financial condition and results of operations. Moreover, our failure to maintain a license to any patent covering any technology that we require may also materially harm our business, financial condition and results of operations. Furthermore, we would be exposed to a threat of litigation.
In the pharmaceutical industry, significant litigation and other proceedings regarding patents, patent applications, trademarks and other intellectual property rights are commonplace. Any such lawsuits and proceedings could be costly and could affect our results of operations and divert the attention of our management and scientific personnel. Some of our competitors may be able to sustain the cost of such litigation and proceedings more effectively than we can because of their substantially greater resources. There is a risk that a court would decide that we or our strategic partners are infringing a third party’s patents and would order us or our strategic partners to stop the activities or stop the manufacture, use, or sale of any product covered by the patents. In that event, we or our strategic partners may not have a viable alternative to the technology protected by the patent and may need to halt work on the affected product candidate or cease commercialization of an approved product. In addition, there is a risk that a court would order us or our strategic partners to pay third-party damages or some other monetary award, depending upon the jurisdiction. An adverse outcome in any litigation or other proceeding could subject us to significant liabilities to third parties, potentially including treble damages and attorneys’ fees if we are found to have willfully infringed, and we may be required to cease using the technology that is at issue or to license the technology from third parties. We may not be able to obtain any required licenses on commercially acceptable terms or at all. Any of these outcomes could have a material adverse effect on our business.
If we are unable to obtain, maintain and enforce patent and trade secret protection for our product candidates and related technology, our business could be materially harmed.
Our strategy depends on our ability to identify and seek patent protection for our discoveries. This process is expensive and time consuming, and we may not be able to file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner or in all jurisdictions where protection may be commercially advantageous. It is also possible that we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection. Moreover, in some circumstances, we may not have the right to control the preparation, filing and prosecution of patent applications, or to maintain the patents, covering technology that we have licensed from third parties. Therefore, our owned or in-licensed patents and patent applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. Our patent applications cannot be enforced against third parties practicing the technology claimed in such applications unless, and until, patents issue from such applications, and then only to the extent the issued claims cover the technology. The patent applications that we own or in-license may fail to result in issued patents with claims that cover our current and future product candidates in the United States or in other countries.
Moreover, the patent position of biopharmaceutical companies generally is highly uncertain, involves complex legal and factual questions and has been the subject of much litigation. The issuance of a patent does not ensure that it is valid or enforceable. Third parties may challenge the validity, enforceability or scope of our issued patents, and such patents may be narrowed, invalidated, circumvented, or deemed unenforceable. In addition, changes in law may introduce uncertainty in the enforceability or scope of patents owned by biotechnology companies. If our patents are narrowed, invalidated or held unenforceable, third parties may be able to commercialize our technology or products and compete directly with us without payment to us. There is no assurance that all potentially relevant prior art relating to our patents and patent applications has been found, and such prior art could potentially invalidate one or more of our patents or prevent a patent from issuing from one or more of our pending patent applications. There is also no assurance that there is not prior art of which we are aware, but which we do not believe affects the validity or enforceability of a claim in our patents and patent applications, which may, nonetheless, ultimately be found to affect the validity or enforceability of a claim.
Furthermore, even if our patents are unchallenged, they may not adequately protect our intellectual property, provide exclusivity for our product candidates, prevent others from designing around our claims or provide us with a competitive advantage. The legal systems of certain countries do not favor the aggressive enforcement of patents, and the laws of other countries may not allow us to protect our inventions with patents to the same extent as the laws of the United States. Because patent applications in the United States and many other jurisdictions are typically not published until 18 months after filing, or in some cases not at all, and because publications of discoveries in scientific literature lag behind actual discoveries, we cannot be certain that we were the first to make the inventions claimed in our issued patents or pending patent applications, or that we were the first to file for protection of the inventions set forth in our patents or patent applications. As a result, we may not be able to obtain or maintain protection for certain inventions. Therefore, the issuance, validity, enforceability, scope and
commercial value of our patents in the United States and in other countries cannot be predicted with certainty and, as a result, any patents that we own or license may not provide sufficient protection against competitors. We may not be able to obtain or maintain patent protection from our pending patent applications, from those we may file in the future, or from those we may license from third parties. Moreover, even if we are able to obtain patent protection, such patent protection may be of insufficient scope to achieve our business objectives. In addition, the issuance of a patent does not give us the right to practice the patented invention. Third parties may have blocking patents that could prevent us from marketing our own patented product and practicing our own patented technology.
Our patents covering one or more of our products or product candidates could be found invalid or unenforceable if challenged.
Any of our intellectual property rights could be challenged or invalidated despite measures we take to obtain patent and other intellectual property protection with respect to our product candidates and proprietary technology. For example, if we were to initiate legal proceedings against a third party to enforce a patent covering one of our product candidates, the defendant could counterclaim that our patent is invalid and/or unenforceable. In patent litigation in the United States and in some other jurisdictions, defendant counterclaims alleging invalidity and/or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, for example, lack of novelty, obviousness or non-enablement. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld material information from the U.S. Patent and Trademark Office (“USPTO”) or the applicable foreign counterpart, or made a misleading statement, during prosecution. A litigant or the USPTO itself could challenge our patents on this basis even if we believe that we have conducted our patent prosecution in accordance with the duty of candor and in good faith. The outcome following such a challenge is unpredictable.
With respect to challenges to the validity of our patents, for example, there might be invalidating prior art, of which we and the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal assertion of invalidity and/or unenforceability, we would lose at least part, and perhaps all, of the patent protection on a product candidate. Even if a defendant does not prevail on a legal assertion of invalidity and/or unenforceability, our patent claims may be construed in a manner that would limit our ability to enforce such claims against the defendant and others. The cost of defending such a challenge, and any resulting loss of patent protection, could have a material adverse impact on one or more of our product candidates and our business.
Enforcing our intellectual property rights against third parties may also cause such third parties to file other counterclaims against us, which could be costly to defend and could require us to pay substantial damages, cease the use, manufacture, or sale of certain products or enter into a license agreement and pay royalties (which may not be possible on commercially reasonable terms or at all). Any efforts to enforce our intellectual property rights are also likely to be costly and may divert the efforts of our scientific and management personnel.
Our intellectual property rights will not necessarily provide us with competitive advantages.
The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations, and may not adequately protect our business, or permit us to maintain our competitive advantage. The following examples are illustrative:
•others may be able to make compounds that are similar to our product candidates but that are not covered by the claims of the patents that we or our strategic partners own or have exclusively licensed;
•others may independently develop similar or alternative technologies without infringing our intellectual property rights;
•issued patents that we own or have exclusively licensed may not provide us with any competitive advantages, or may be held invalid or unenforceable, as a result of legal challenges by our competitors;
•we may obtain patents for certain compounds many years before we obtain marketing approval for products containing such compounds, and because patents have a limited life, which may begin to run prior to the commercial sale of the related product, the commercial value of our patents may be limited;
•our competitors might conduct research and development activities in countries where we do not have patent rights and then use the information learned from such activities to develop competitive products for sale in our major commercial markets;
•we may fail to develop additional proprietary technologies that are patentable;
•the laws of certain countries may not protect our intellectual property rights to the same extent as the laws of the United States, or we may fail to apply for or obtain adequate intellectual property protection in all the jurisdictions in which we operate; and
•the patents of others may have an adverse effect on our business, for example by preventing us from marketing one or more of our product candidates for one or more indications.
Any of the aforementioned threats to our competitive advantage could have a material adverse effect on our business.
We may become involved in lawsuits to protect or enforce our patents and trade secrets, which could be expensive, time consuming and unsuccessful.
Third parties may seek to market biosimilar versions of any approved products. Alternatively, third parties may seek approval to market their own products similar to or otherwise competitive with our product candidates. In these circumstances, we may need to defend or assert our patents, including by filing lawsuits alleging patent infringement. The outcome following legal assertions of invalidity and unenforceability is unpredictable. In any of these types of proceedings, a court or agency with jurisdiction may find our patents invalid or unenforceable. Even if we have valid and enforceable patents, these patents still may not provide protection against competing products or processes sufficient to achieve our business objectives.
Even after they have issued, our patents and any patents that we license may be challenged, narrowed, invalidated or circumvented. If our patents are invalidated or otherwise limited or will expire prior to the commercialization of our product candidates, other companies may be better able to develop products that compete with ours, which could adversely affect our competitive business position, business prospects and financial condition. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates.
The following are examples of litigation and other adversarial proceedings or disputes that we could become a party to involving our patents or patents licensed to us:
•we or our strategic partners may initiate litigation or other proceedings against third parties to enforce our patent or trade secret rights;
•third parties may initiate litigation or other proceedings seeking to invalidate patents owned by or licensed to us or to obtain a declaratory judgment that their product or technology does not infringe our patents or patents licensed to us;
•third parties may initiate opposition or reexamination proceedings challenging the validity or scope of our patent rights, requiring us or our strategic partners and/or licensors to participate in such proceedings to defend the validity and scope of our patents;
•there may be a challenge or dispute regarding inventorship or ownership of patents or trade secrets currently identified as being solely or co-owned by us or by a licensor who has granted a license to us;
•the USPTO may initiate an interference between patents or patent applications owned by or licensed to us and those of our competitors, requiring us or our strategic partners and/or licensors to participate in an interference proceeding to determine the priority of invention, which could jeopardize our patent rights; or
•third parties may seek approval to market biosimilar versions of our future approved products prior to expiration of relevant patents owned by or licensed to us, requiring us to defend our patents, including by filing lawsuits alleging patent infringement.
These lawsuits and proceedings would be costly and could affect our results of operations and divert the attention of our managerial and scientific personnel. Adversaries in these proceedings may have the ability to dedicate substantially greater resources to prosecuting these legal actions than we or our licensors can. There is a risk that a court or administrative body would decide that our patents are invalid, unenforceable or not infringed or trade secrets not misappropriated by a third party’s activities, or that the scope of certain issued claims must be further limited. An adverse outcome in a litigation or proceeding involving our own patents or trade secrets could limit our ability to assert our patents or trade secrets against these or other competitors, affect our ability to receive royalties or other licensing consideration from our licensees, and may curtail or preclude our ability to exclude third parties from making, using and selling similar or competitive products. Any of these occurrences could adversely affect our competitive business position, business prospects and financial condition.
We may not be able to prevent, alone or with our licensors or licensees, infringement or misappropriation of our intellectual property rights, particularly in countries where the laws may not protect those rights as fully as in the United States. Any
litigation or other proceedings to enforce our intellectual property rights may fail, and even if successful, may result in substantial costs and distract our management and other employees.
Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. There could also 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 an adverse effect on the price of our common stock.
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:
•others may be able to develop a platform that is similar to, or better than, ours in a way that is not covered by the claims of our patents;
•others may be able to make compounds that are similar to our product candidates but that are not covered by the claims of our patents;
•we might not have been the first to make the inventions covered by patents or pending patent applications;
•we might not have been the first to file patent applications for these inventions;
•any patents that we obtain may not provide us with any competitive advantages or may ultimately be found invalid or unenforceable; or
•we may not develop additional proprietary technologies that are patentable or that afford meaningful trade secret protection.
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 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 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.
If we do not obtain protection under the Hatch-Waxman Amendments and similar legislation in other countries for extending the term of patents covering each of our product candidates, our business may be materially harmed.
Depending upon the timing, duration and conditions of FDA marketing approval of our product candidates, one or more of our U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent term extension of up to five years for a patent covering an approved product as compensation for effective patent term lost during product development and the FDA regulatory review process. However, we may not receive an extension if we fail to apply within applicable deadlines, fail to apply prior to expiration of relevant patents or otherwise fail to satisfy applicable requirements. Moreover, the length of the extension could be less than we request. If we are unable to obtain patent term extension or the term of any such extension is less than we request, the period during which we can enforce our patent rights for that product will be shortened and our competitors may obtain approval to market competing products sooner. As a result, our revenue from applicable products could be reduced, possibly materially. Further, if this occurs, our competitors may take advantage of our investment in development and trials by referencing our clinical and preclinical data and launch their product earlier than might otherwise be the case.
If we are unable to protect the confidentiality of our proprietary information, the value of our technology and products could be adversely affected.
In addition to patent protection, we also rely on other proprietary rights, including protection of trade secrets, and other proprietary information. For example, we treat our confidential and proprietary computational technologies, including unpatented know-how and other proprietary information, as trade secrets. We enter into confidentiality agreements with our employees, consultants, strategic partners and others upon the commencement of their relationships with us. These agreements
provide that all confidential information developed by the individual or made known to the individual by us during the course of the individual’s relationship with us be kept confidential and not disclosed to third parties. Our agreements with employees and our personnel policies also provide that any inventions conceived by the individual in the course of rendering services to us shall be our exclusive property. However, we may not obtain these agreements in all circumstances, and individuals with whom we have these agreements may not comply with their terms. We cannot guarantee that we have entered into such agreements with each party that has or may have had access to, or houses or hosts, our trade secrets or proprietary information or that has been involved in the development of intellectual property. Further, despite such agreements, such inventions or confidential information may become disclosed or assigned to third parties. Monitoring unauthorized uses and disclosures is difficult and we do not know whether the steps we have taken to protect our proprietary technologies will be effective. In the event of unauthorized use or disclosure of our trade secrets or proprietary information, these agreements, even if obtained, may not provide meaningful protection, particularly for our trade secrets or other confidential information. To the extent that our employees, consultants or contractors use technology or know-how owned by third parties in their work for us, disputes may arise between us and those third parties as to the rights in such technology or know-how or in related inventions. To the extent that an individual who is not obligated to assign rights in intellectual property to us is rightfully an inventor of intellectual property, we may need to obtain an assignment or a license to that intellectual property from that individual, or a third party or from that individual’s assignee. Such assignment or license may not be available on commercially reasonable terms or at all.
We also seek to preserve the integrity and confidentiality of our data and trade secrets by maintaining physical security of our premises and physical and electronic security of our information technology systems and cloud storage sources, but such security measures may be breached, including through cyber-hacking or cyberattacks, and we may not have adequate remedies for any breach.
Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming and the outcome is unpredictable. In addition, some courts inside and outside the United States are less willing or unwilling to protect trade secrets. The disclosure of our trade secrets would impair our competitive position and may materially harm our business, financial condition and results of operations. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to maintain trade secret protection could adversely affect our competitive business position. In addition, if any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent such third party, or those to whom they communicate such technology or information, from using that technology or information to compete with us. If any of our trade secrets were to be disclosed to or independently developed by a competitor, or if we otherwise lose protection for our trade secrets or proprietary know-how, the value of this information may be greatly reduced and our business and competitive position could be harmed. Adequate remedies may not exist in the event of unauthorized use or disclosure of our proprietary information.
As is common in the biotechnology and pharmaceutical industries, we employ individuals who were previously or concurrently employed at research institutions and/or other biotechnology or pharmaceutical companies, including our competitors or potential competitors. We may be subject to claims that these employees, or we, have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers, or that patents and applications we have filed to protect inventions of these employees, even those related to one or more of our product candidates, are rightfully owned by their former or concurrent employer. Litigation may be necessary to defend against these claims. Such trade secrets or other proprietary information could be awarded to a third party, and we could be required to obtain a license from such third party to commercialize our technology or products. Such license may not be available on commercially reasonable terms or at all. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.
Obtaining and maintaining our patent protection depends on compliance with various procedural, documentary, fee payment and other requirements imposed by regulations and governmental patent agencies, and our patent protection could be reduced or eliminated for noncompliance with these requirements.
Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents or applications will be due to the USPTO and various foreign patent offices at various points over the lifetime of our patents or applications. We have systems in place to remind us to pay these fees, and we rely on our outside patent annuity service to pay these fees when due. Additionally, the USPTO and various foreign patent offices 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 rules applicable to the particular jurisdiction. However, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. If such an event were to occur, it could have a material adverse effect on our business.
We may be subject to claims challenging the inventorship of our patents and other intellectual property.
Although we are not currently experiencing any claims challenging the inventorship or ownership of our patents, we may in the future be subject to claims that former employees, strategic partners or other third parties have an interest in our patents or other intellectual property as an inventor or co-inventor. While it is our policy to 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. For example, the assignment of intellectual property rights may not be self-executing or the assignment agreements may be breached, or we may have inventorship disputes arise from conflicting obligations of consultants or others who are involved in developing our product candidates. Litigation may be necessary to defend against these and other claims challenging inventorship. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of, or right to use, valuable intellectual property. 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.
Patent protection and patent prosecution for some of our product candidates may be dependent on, and the ability to assert patents and defend them against claims of invalidity may be maintained by, third parties.
There may be times in the future when certain patents that relate to our product candidates or any approved products are controlled by our licensees or licensors. Although we may, under such arrangements, have rights to consult with our strategic partners on actions taken as well as back-up rights of prosecution and enforcement, we have in the past and may in the future relinquish rights to prosecute and maintain patents and patent applications within our portfolio as well as the ability to assert such patents against infringers.
If any current or future licensee or licensor with rights to prosecute, assert or defend patents related to our product candidates fails to appropriately prosecute and maintain patent protection for patents covering any of our product candidates, or if patents covering any of our product candidates are asserted against infringers or defended against claims of invalidity or unenforceability in a manner that adversely affects such coverage, our ability to develop and commercialize any such product candidate may be adversely affected and we may not be able to prevent competitors from making, using and selling competing products.
Changes in patent laws or patent jurisprudence could diminish the value of patents in general, thereby impairing our ability to protect our products.
The patent positions of pharmaceutical and biotechnology companies can be highly uncertain and involve complex legal and factual questions for which important legal principles remain unresolved. Changes in either the patent laws or in the interpretations of patent laws in the United States and other countries may diminish the value of our intellectual property. We cannot predict the breadth of claims that may be allowed or found to be enforceable in our patents, in our strategic partners’ patents or in third-party patents. Recent U.S. Supreme Court rulings have either narrowed the scope of patent protection available in certain circumstances or weakened the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this has created uncertainty with respect to the validity, scope and value of patents, once obtained.
For our U.S. patent applications containing a priority claim after March 16, 2013, there is a greater level of uncertainty in the patent law. In September 2011, the Leahy-Smith America Invents Act, also known as the America Invents Act (“AIA”), was signed into law. The AIA includes a number of significant changes to U.S. patent law, including provisions that affect the way patent applications will be prosecuted and may also affect patent litigation.
The AIA and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could have an adverse effect on our business. An important change introduced by the AIA is that, as of March 16, 2013, the United States transitioned to a “first-to-file” system for deciding which party should be granted a patent when two or more patent applications are filed by different parties disclosing or claiming the same invention. A third party that has filed, or files a patent application in the USPTO after March 16, 2013, but before us, could be awarded a patent covering a given invention, even if we had made the invention before it was made by the third party. This requires us to be cognizant of the time from invention to filing of a patent application.
Among some of the other changes introduced by the AIA are changes that limit where a patentee may file a patent infringement suit and providing opportunities for third parties to challenge any issued patent in the USPTO. This applies to all of our U.S.
patents, even those issued before March 16, 2013. Because of a lower evidentiary standard in USPTO proceedings compared to the evidentiary standard in U.S. federal court 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.
Depending on decisions by the U.S. Congress, the U.S. federal courts, the USPTO or similar authorities in foreign jurisdictions, the laws and regulations governing patents could change in unpredictable ways that may weaken our and our licensors’ ability to obtain new patents or to enforce existing patents we and our licensors or partners may obtain in the future.
We may not be able to protect our intellectual property rights throughout the world.
Filing, prosecuting and defending patents on 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 countries do not protect intellectual property rights to the same extent as laws in the United States. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States, or from selling or importing 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 further, may export otherwise 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 current or future products, if any, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing. Recent U.S. Supreme Court cases have narrowed the scope of what is considered patentable subject matter, for example, in the areas of software and diagnostic methods involving the association between treatment outcome and biomarkers. This could impact our ability to patent certain aspects of our technology in the United States.
Many companies have encountered significant problems in protecting and defending intellectual property rights in jurisdictions other than the United States. The legal systems of certain 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 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.
Additionally, the requirements for patentability may differ in certain countries. For example, China has a heightened requirement for patentability, and specifically requires a detailed description of medical uses of a claimed drug. In India, unlike the United States, there is no link between regulatory approval of a drug and its patent status. In addition to India, certain countries in Europe and developing countries, including China, have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In those countries, we and our licensors may have limited remedies if patents are infringed or if we or our licensors are compelled to grant a license to a third party, which could materially diminish the value of those patents. This could limit our potential revenue opportunities. Accordingly, our efforts to enforce intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we own or license.
Geo-political actions in the United States and in foreign countries could increase the uncertainties and costs surrounding the prosecution or maintenance of our patent applications or those of any current or future licensors or licensees and the maintenance, enforcement or defense of our issued patents or those of any current or future licensors or licensees. For example, the United States, Canadian, and foreign government actions related to Russia’s invasion of Ukraine may limit or prevent filing, prosecution and maintenance of patent applications in Russia. Government actions may also prevent maintenance of issued patents in Russia. These actions could result in abandonment or lapse of our patents or patent applications, resulting in partial or complete loss of patent rights in Russia. If such an event were to occur, it could have a material adverse effect on our business. In addition, a decree was adopted by the Russian government in March 2022, allowing Russian companies and individuals to exploit inventions owned by patentees that have citizenship or nationality in, are registered in, or have a predominately primary place of business or profit-making activities in the United States and other countries that Russia has deemed unfriendly without consent or compensation. Consequently, we would not be able to prevent third parties from practicing our inventions in Russia
or from selling or importing products made using our inventions in and into Russia. Accordingly, our competitive position may be impaired, and our business, financial condition, results of operations and prospects may be adversely affected.
As another example, the complexity and uncertainty of European patent laws have increased in recent years. In Europe, a new unitary patent system will likely be introduced by the end of 2023, which would significantly impact European patents, including those granted before the introduction of such a system. Under the unitary patent system, European applications will soon have the option, upon grant of a patent, of becoming a Unitary Patent which will be subject to the jurisdiction of the Unitary Patent Court (UPC). As the UPC is a new court system, there is no precedent for the court, increasing the uncertainty of any litigation. Patents granted before the implementation of the UPC will have the option of opting out of the jurisdiction of the UPC and remaining as national patents in the UPC countries. Patents that remain under the jurisdiction of the UPC will be potentially vulnerable to a single UPC-based revocation challenge that, if successful, could invalidate the patent in all countries who are signatories to the UPC. We cannot predict with certainty the long-term effects of any potential changes.
We use open source software in connection with our internal research and development programs, which could negatively affect our ability to develop products and subject us to litigation or other actions.
We use open source software in connection with our internal research and development programs. The terms of many open source licenses have not been interpreted by U.S. courts or courts outside of the U.S., and there is a risk that these licenses could be construed in a way that could impose unanticipated conditions or restrictions on our ability to use this software. As a result, we could be subject to lawsuits by parties claiming ownership of what we believe to be open source software, or claiming that software we developed using such open source software is a derivative work of open source software and demanding the release of portions of our source code, or otherwise seeking to enforce the terms of the applicable open source license. Litigation could be costly for us to defend, have a negative effect on our financial condition and results of operations or require us to devote additional research and development resources to change our platform and offerings.
If we were to combine our proprietary software with open source software in a certain manner, we could, under certain open source licenses, be required to release the source code of our proprietary software to the public. While we monitor our use of open source software and try to ensure that none is used in a manner that would require us to disclose our proprietary source code or that would otherwise breach the terms of an open source agreement, such use could inadvertently occur, or could be claimed to have occurred, in part because open source license terms are often ambiguous. If we inappropriately use open source software, or if the license terms for open source software that we use change, we may be required to re-engineer our platform, incur additional costs, discontinue the use of some or all of our platform or take other remedial actions.
In addition to risks related to license requirements, usage of open source software can lead to greater risks than use of third-party commercial software, because open source licensors generally do not provide warranties or assurance of title or controls on origin of the software. In addition, many of the risks associated with usage of open source software, such as the lack of warranties or assurances of title, cannot be eliminated, and could, if not properly addressed, negatively affect our business. We have established processes to help alleviate these risks, including a review process for the use of open source software, but we cannot be sure that all of our use of open source software is in a manner that is consistent with our current policies and procedures, or will not subject us to liability. Any of these risks could be difficult to eliminate or manage and, if not addressed, could have an adverse effect on our business, financial condition and results of operations.
We will need to obtain FDA approval for any proposed product candidate names, and any failure or delay associated with such approval may adversely affect our business.
Any proprietary name or trademark we intend to use for our product candidates will require approval from the FDA regardless of whether we have secured a formal trademark registration from the USPTO. The FDA typically conducts a review of proposed product candidate names, including an evaluation of the potential for confusion with other product names. The FDA may also object to a product name if it believes the name inappropriately implies certain medical claims or contributes to an overstatement of efficacy. If the FDA objects to any product candidate names we propose, we may be required to adopt an alternative name for our product candidates. If we adopt an alternative name, we would lose the benefit of any existing trademark applications for such product candidate and may be required to expend significant additional resources in an effort to identify a suitable product name that would qualify under applicable trademark laws, not infringe the existing rights of third parties and be acceptable to the FDA. We may be unable to build a successful brand identity for a new trademark in a timely manner or at all, which would limit our ability to commercialize our product candidates.
Risks Related to the Redomicile Transactions
We may fail to realize certain benefits of the Redomicile Transactions, including as a result of the shares of our common stock not being included in a U.S. stock market index.
We believe that the Redomicile Transactions will enhance stockholder value over the long-term and raise the profile and marketability of our capital stock in the United States through, among other things, the ability to attract deeper and growing pools of passive investment capital in the United States, particularly if shares of our common stock are included in certain U.S. stock market indices and other investment vehicles that only include securities of U.S.-incorporated companies. However, if shares of our common stock are not included in such U.S. stock market indices, this could result in increased selling pressure and/or decreased demand for our common stock that would increase stock price volatility or cause the market price of the shares of our common stock to fall. Initial inclusion and continued inclusion in a stock market index or fund is not guaranteed and is subject to numerous factors which can be applied subjectively by the entity managing the index or fund. There are no assurances that we will be included in any U.S. stock market indices or funds in a timely manner, or at all. Even if we are included in a U.S. stock market index or fund, the entities managing such indices or funds may change their inclusion criteria, resulting in the future exclusion from such index or fund.
In addition, we incurred a number of non-recurring costs associated with the Redomicile Transactions, including legal fees, accountants’ fees, proxy solicitor fees, filing fees, mailing expenses and financial printing expenses. The completion of the Redomicile Transactions and the associated reorganization of our corporate structure may result in additional and unforeseen expenses in the future. While it is expected that benefits of the Redomicile Transactions will offset these transaction costs over time, this net benefit may not be achieved in the short-term or at all. These combined factors could adversely affect our business and overall financial condition. The success of the Redomicile Transactions will depend, in part, on our ability to realize the anticipated benefits associated with the Redomicile Transactions and associated reorganization of our corporate structure, and we may not be able to realize such benefits on a timely basis or at all.
The Redomicile Transactions may result in sales of shares of our common stock by certain retail and institutional stockholders or investment funds that are not permitted to hold shares of our common stock under their internal guidelines.
The Redomicile Transactions may result in sales of shares of our common stock by certain retail and institutional stockholders or investment funds (including Canadian-focused funds) that are not permitted to hold shares of our common stock under their internal guidelines, or are limited in the size of any such investments. Such sales could result in increased selling pressure and/or decreased demand for shares of our common stock, which could increase stock price volatility or cause the market price of the shares of our common stock to fall. As a result of the foregoing, certain of these investors may be required under their internal guidelines to sell their shares at times when, or at prices for which, they would otherwise not have sold. If an investor sells its shares at a time when the market price is lower than their cost basis in the shares, the investor will suffer a loss that could be significant to such investor.
Our business may be impacted by the uncertainty associated with the Redomicile Transactions.
Following completion of the Redomicile Transactions, our principal executive offices are located in Middletown, Delaware. We have physical operations and personnel in Canada, the United States, and Ireland, and maintain offices in these three countries. Our executive officers and directors are located in several jurisdictions, including the United States, Canada and the United Kingdom.
Certain relationships, including with employees, suppliers, CROs, partners, collaborators, governments and other stakeholders, may be subject to disruption due to uncertainty associated with the Redomicile Transactions. Specifically, certain stakeholders may be reluctant to engage in business with us following the completion of the Redomicile Transactions or may impose additional conditions on or apply less favorable terms to transactions involving us. This could have an adverse effect on our business and operations.
In connection with the completion of the Redomicile Transactions we may need to enter into certain new arrangements which may not be on terms as favorable as arrangements entered into by Zymeworks BC.
In connection with completion of the Redomicile Transactions we may need to enter into new arrangements as the ultimate parent company to Zymeworks BC and its subsidiaries. While we anticipate such terms will be materially consistent with existing arrangements, there is no assurance that such arrangement will not impose additional operating or financial restrictions on us, or that such arrangements will be on commercially reasonable terms or terms that are acceptable to us.
In addition, the completion of the Redomicile Transactions may have triggered certain technical change in control, right of first offer, notice, consent, assignment or other provisions in agreements to which Zymeworks BC or our other subsidiaries are a party. If we are unable to assert that such provisions should not apply, or we are unable to comply with or negotiate waivers of those provisions, the counterparties may exercise their rights and remedies under the agreements, including potentially terminating such agreements or seeking monetary damages. Even if we are able to negotiate waivers, the counterparties may require a fee for such waivers or seek to renegotiate the agreements on terms less favorable to us.
Negative publicity resulting from the Redomicile Transactions could adversely affect our business and the market price of our common stock.
Transactions similar to the Redomicile Transactions that have been undertaken by other companies have in some cases generated significant news coverage, some of which has been negative. Negative publicity generated by the Redomicile Transactions could cause certain persons with whom we have a business relationship to be more reluctant to do business with us. In addition, negative publicity could cause certain of our employees, particularly those in Canada, to perceive uncertainty regarding future opportunities available to them. Either of these events could have a significant adverse impact on our business. Negative publicity could also cause some of our stockholders to sell their shares or decrease the demand for new investors to purchase such shares, which could have an adverse impact on the price of our common stock.
Our current organizational structure may result in certain tax and operational inefficiencies that may adversely affect our business, financial condition and results of operations.
On October 13, 2022, the Redomicile Transactions were completed, which were governed by a transaction agreement dated July 14, 2022, as restated and amended on August 18, 2022 (the “Restated and Amended Transaction Agreement”), by and among Zymeworks BC, us, CallCo and ExchangeCo. Pursuant to the terms of the Restated and Amended Transaction Agreement, we, Zymeworks BC, CallCo and ExchangeCo agreed, among other things, to use reasonable efforts to take certain corporate steps and actions, as may be necessary or desirable, to effect and implement certain post-arrangement transactions following the implementation of the arrangement under the BCBCA (the “Post-Arrangement Transactions”), including the movement of certain subsidiaries of Zymeworks BC so that they become our directly, wholly-owned subsidiaries. Following Zymeworks BC’s entry into the Jazz Collaboration Agreement, we reevaluated the potential impacts of completing the Post-Arrangement Transactions and have determined that completing the Post-Arrangement Transactions as contemplated in the Restated and Amended Transaction Agreement would result in negative tax consequences. As a result, we are evaluating alternatives to the previously contemplated Post-Arrangement Transactions with our advisors. We cannot be certain that we will be able to identify and implement an alternative set of post-arrangement transactions. Even if we do identify an alternative set of post-arrangement transactions, we cannot be certain that such alternative will result in a more tax-efficient or operationally-efficient organizational structure. While we are evaluating alternative approaches, our current organizational structure may result in certain tax and operational inefficiencies that may adversely affect our business, financial condition and results of operations.
Our effective tax rate may change in the future.
We are subject to U.S. federal income taxes on our earnings and the earnings of our non-U.S. subsidiaries in a manner that may adversely impact our effective tax rate. For example, we may have to include additional amounts in income under the so-called “global intangible low-taxed income” regime or as a result of the application of “controlled foreign corporation” rules. In addition, the United States has enacted the Inflation Reduction Act, which, among other changes, imposes a 1% excise tax on certain stock buybacks and an alternative minimum tax on adjusted financial statement income. In addition, our Canadian tax attributes (including net operating loss and tax credit carryforwards and deductible Scientific Research and Experimental Development Expenditure carryforwards) will generally not be available to offset U.S. income and may be subject to limitation.
Further, our future operations and business structure may result in increased tax burden. For example, changes in our clinical development plans and business or commercialization strategies may result in an increased effective tax rate. Taxation of international business operations and intercompany transactions, including transactions between us and non-U.S. subsidiaries, is complicated. Any changes in the U.S. or non-U.S. taxation of such activities may increase our worldwide effective tax rate and harm our business, financial condition, and results of operations.
Enforcement of rights against us in Canada may be limited.
Following the Redomicile Transactions, our principal executive offices are located in Middletown, Delaware and the majority of our directors, officers and experts reside outside of Canada. Accordingly, it may not be possible for our stockholders to effect service of process within Canada upon us or the majority of our directors, officers or experts, or to enforce judgments obtained in Canadian courts against us or the majority of our directors, officers or experts.
Risks Related to the Exchangeable Shares
The Exchangeable Shares will not be listed on any stock exchange.
Pursuant to the Redomicile Transactions, holders of Zymeworks BC common shares exchanged their Zymeworks BC common shares for shares of our common stock or, at their election with respect to all or a portion of their Zymeworks BC common shares and subject to applicable eligibility criteria and an overall cap, exchangeable shares (the “Exchangeable Shares”) in the capital of ExchangeCo. The Exchangeable Shares will not be listed on any stock exchange. Although Exchangeable Shares are exchangeable at the option of the holder for shares of our common stock, there is no market through which the Exchangeable Shares may be sold, and holders may not be able to sell their Exchangeable Shares.
Holders of Exchangeable Shares may experience a delay in receiving shares of our common stock from the date they request an exchange, which may affect the value of the shares the holder receives in such exchange.
Holders of Exchangeable Shares who request an exchange may not receive shares of our common stock until a period of time after the applicable request is received. During this period, the market price of our common stock may increase or decrease. Any such increase or decrease would affect the value of the consideration to be received by such a holder of Exchangeable Shares upon a subsequent sale of shares of our common stock received in the exchange.
There may be a taxable event for a holder of Exchangeable Shares beyond such holder’s control.
A holder of Exchangeable Shares will be considered to have disposed of Exchangeable Shares (i) on a redemption (including pursuant to a retraction request) of such Exchangeable Shares by holders of Exchangeable Shares or ExchangeCo, and (ii) on an acquisition of such Exchangeable Shares by us or CallCo. Although each is a taxable event, the Canadian federal income tax consequences of the disposition will be different depending on whether the event giving rise to the disposition is a redemption or an acquisition.
Prior to the sunset date of the Exchangeable Shares, ExchangeCo may redeem Exchangeable Shares in limited circumstances, and ExchangeCo shall redeem the Exchangeable Shares on the sunset date. Accordingly, an Eligible Holder may have a taxable event in a transaction beyond their control.
The tax treatment of Exchangeable Shares for non-Canadian tax purposes is uncertain.
The tax treatment of Exchangeable Shares for non-Canadian tax purposes, including U.S. federal income tax purposes, is uncertain. Holders of Exchangeable Shares who are subject to taxation in jurisdictions other than Canada should consult with their tax advisors regarding the tax treatment of Exchangeable Shares under non-Canadian tax laws and regulations.
Risks Related to Additional Legal and Compliance Matters
Our employees may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, insider trading, and noncompliance with our policies and procedures.
We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees could include intentional failures to comply with FDA regulations, to provide accurate information to the FDA, to comply with federal and state health care fraud and abuse laws and regulations, to report financial information or data accurately or to disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the health care industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, 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. Employee misconduct 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. We have adopted a Code of Conduct and Business Ethics, but it is not always possible to identify and deter employee misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant fines or other sanctions. In addition, employees may become subject of allegations of gender discrimination and other misconduct that are not in compliance with our policies and procedures, which, regardless of the ultimate outcome, may result in adverse publicity that could materially harm our brand, reputation and business.
If we or our contractors or agents market products in a manner that violates healthcare fraud and abuse laws, or if we violate government price reporting laws and transparency laws, we may be subject to civil or criminal penalties.
In addition to FDA restrictions on the marketing of pharmaceutical products, federal and state healthcare laws restrict certain business practices in the biopharmaceutical industry. Although we currently do not have any products on the market, we may be subject, and if our product candidates are approved and we begin commercialization will be subject, to additional healthcare laws and regulations enforced by the federal government and by authorities in the states and foreign jurisdictions in which we conduct our business. These state and federal healthcare laws, commonly referred to as “fraud and abuse” laws, have been applied to restrict certain marketing practices in the pharmaceutical industry, and include anti-kickback, false claims, data privacy and security and transparency statutes and regulations.
Federal false claims laws prohibit, among other things, 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. The federal healthcare program anti-kickback statute 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 healthcare item or service reimbursable under Medicare, Medicaid or other federally financed healthcare programs. Most states also have statutes or regulations similar to the federal anti-kickback law and federal false claims laws, which may apply to items such as pharmaceutical products and services reimbursed by private insurers. Administrative, civil and criminal sanctions may be imposed under these federal and state laws.
The federal civil monetary penalties statute imposes penalties against any person or entity who, among other things, is determined to have presented or caused to be presented a claim to a federal health program that the person knows or should know is for an item or service that was not provided as claimed or is false or fraudulent.
HIPAA created new federal criminal statutes that prohibit knowingly and willfully executing, or attempting to execute, a scheme to defraud or obtain, by means of false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit program, including private third-party payors, and 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, healthcare benefits, items or services.
In addition, we may be subject to data privacy and security regulation by both the federal government and the states in which we conduct our business. HIPAA, as amended by HITECH, and its implementing regulations, imposes certain requirements relating to the privacy, security and transmission of individually identifiable health information. Among other things, HITECH makes HIPAA’s security standards directly applicable to business associates-independent contractors or agents of covered entities that receive or obtain protected health information in connection with providing a service on behalf of a covered entity. HITECH also created four new tiers of civil monetary penalties, and newly empowered state attorneys general with the authority to enforce HIPAA. In January 2013, the Office for Civil Rights of the U.S. Department of Health and Human Services issued the Final Omnibus Rule under HIPAA pursuant to HITECH that makes significant changes to the privacy, security and breach notification requirements and penalties. The Final Omnibus Rule generally took effect in September 2013 and enhances certain privacy and security protections, and strengthens the government’s ability to enforce HIPAA. The Final Omnibus Rule also enhanced requirements for both covered entities and business associates regarding notification of breaches of unsecured protected health information. In addition, state laws govern the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways. These state laws may not have the same effect and often are not preempted by HIPAA, thus complicating compliance efforts.
Additionally, the PPACA also included the federal Physician Payments Sunshine Act, which requires applicable group purchasing organizations and manufacturers of 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 information related to certain payments or other transfers of value made in the previous year to covered recipients, including physicians, as defined by law, and teaching hospitals and, effective for data reported in 2022, expanded to include nurse practitioners, physician assistants, clinical nurse specialists, certified registered nurse anesthetists and anesthesiologist assistants, and certified nurse-midwives, including certain ownership and investment interests held by physicians or their immediate family members. Failure to comply with the required reporting requirements could subject applicable reporting entities such as manufacturers to substantial civil monetary penalties.
Also, many states have similar healthcare statutes or regulations that apply to items and services reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payor. Certain states require pharmaceutical companies to implement a comprehensive compliance program that includes a limit or outright ban on expenditures for, or payments to,
individual medical or health professionals and/or require pharmaceutical companies to track and report gifts and other payments made to physicians and other healthcare providers.
If our operations are found to be in violation of any of the healthcare laws or regulations described above or any other laws that apply to us, we may be subject to penalties, including potentially significant criminal, civil or administrative penalties, damages, fines, disgorgement, individual imprisonment, exclusion of products from reimbursement under government programs, contractual damages, reputational harm, administrative burdens, diminished profits and future earnings or the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations. To the extent that any of our products will be sold in a foreign country, we may be subject to similar foreign laws and regulations, which may include, for instance, applicable post-marketing requirements, including safety surveillance, fraud and abuse laws, and implementation of corporate compliance programs and reporting of payments or transfers of value to healthcare professionals.
If we do not comply with laws regulating the protection of the environment and health and human safety, our business could be adversely affected.
Our research and development involves, and may in the future involve, the use of potentially hazardous materials and chemicals. Our operations may produce hazardous waste products. Although we believe that our safety procedures for handling and disposing of these materials comply with the standards mandated by local, state and federal laws and regulations, the risk of accidental contamination or injury from these materials cannot be eliminated. If an accident occurs, we could be held liable for resulting damages, which could be substantial. We are also subject to numerous environmental, health and workplace safety laws and regulations and fire and building codes, including those governing laboratory procedures, exposure to blood-borne pathogens, use and storage of flammable agents and the handling of biohazardous materials. Although we maintain workers’ compensation insurance as prescribed by certain jurisdictions in which we operate to cover us for costs and expenses we may incur due to injuries to our employees resulting from the use of these materials, this insurance may not provide adequate coverage against potential liabilities. We do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us. Additional federal, state and local laws and regulations affecting our operations may be adopted in the future. We may incur substantial costs to comply with, and substantial fines or penalties if we violate, any of these laws or regulations.
Risks Related to Employee Matters and Managing Growth
We may fail to achieve the expected cost savings and related benefits from our 2022 reduction in workforce.
In January 2022, we announced a plan to reduce our workforce to reflect our renewed focus on key priorities and enable us to help achieve a more cost-efficient organization necessary to execute on those priorities. While we completed the reduction in workforce by the end of 2022, the full impact of the reduction in workforce is not yet known.
We may fail to effectively achieve the stated goals of the reduction in workforce. Our plans may also change as we continue to refocus on our key priorities. These actions may take more time than we currently estimate and we may not be able to achieve the cost-efficiencies sought. In addition, while the reduction in workforce was completed in 2022, it may still negatively impact employee morale for those that were not directly impacted, which may increase employee attrition and hinder our ability to achieve our key priorities. Any failure to achieve the expected benefits from the reduction in workforce or from other recent management and personnel related changes could adversely affect our stock price, financial condition and ability to achieve our key priorities.
Our future success depends on our ability to retain key executives and to attract, retain and motivate qualified personnel.
We are highly dependent on key members of our senior management team, including Kenneth Galbraith, the Chair of our board of directors and Chief Executive Officer, Neil Klompas, our President and Chief Operating Officer, Christopher Astle, our Chief Financial Officer, Paul Moore, our Chief Scientific Officer, and other key members of our senior management, scientific and clinical teams. Although we have entered into employment agreements with our executive officers, each of them may terminate their employment with us at any time. The loss of the services of our key senior managers and employees could impede the achievement of our research, development and commercialization objectives and seriously harm our ability to successfully implement our business strategy.
Retention and any future recruitment of qualified scientific, technical, clinical, manufacturing and sales and marketing personnel will also be critical to our success. In addition, we will need to effectively manage our managerial, operational,
financial, development and other resources in order to successfully pursue our research, development and commercialization efforts for our existing and future product candidates. Furthermore, replacing key senior managers and employees may be difficult and may take an extended period of time because of the limited talent pool in our industry due to the breadth of skills and experience required to successfully develop, gain regulatory approval of and commercialize products. The reduction in workforce announced in January 2022 may also make retention of our current personnel both more important and more challenging. Intense competition for attracting key skill-sets and the impact of inflationary pressure on wages may limit our ability to attract, retain and motivate key personnel on acceptable terms. We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and development and commercialization strategy. Our consultants and advisors may be employed by employers other than us and may have commitments under consulting or advisory contracts with other entities that may limit their availability. If we are unable to continue to attract and retain high quality personnel, our ability to pursue our business strategy will be limited.
As we advance our development and commercialization plans and strategies, we may need to grow or modify our organization, and we may experience difficulty in managing such change, which could disrupt our operations.
As of December 31, 2022, we had 291 full-time employees. As we advance our development and commercialization plans and strategies in the future, we anticipate that we may need to expand or modify our employee base. Additionally, as our product candidates enter and advance through preclinical studies and any clinical trials, we may need to expand our development, manufacturing, regulatory sales and marketing capabilities or contract with other organizations to provide these capabilities for us. Future growth would impose significant added responsibilities on members of management, including the need to identify, recruit, maintain, motivate and integrate additional employees. Also, our management may need to divert a disproportionate amount of their attention away from our day-to-day activities and devote a substantial amount of time to managing any necessary growth activities. We may not be able to effectively manage an expansion of our operations, which may result in weaknesses in our infrastructure, give rise to operational errors, loss of business opportunities, loss of employees and reduced productivity amongst remaining employees. Any growth could require significant capital expenditures and may divert financial resources from other projects, such as the development of existing and additional product candidates. If our management is unable to effectively manage any needed growth, our expenses may increase more than expected, our ability to generate or grow revenue could be reduced and we may not be able to implement our business strategy. Our future financial performance and our ability to commercialize our product candidates and compete effectively with others in our industry will depend on our ability to effectively manage any future growth.
Risks Related to Our Common Stock
Our stock price is likely to be volatile and the market price of our common stock may drop below the price paid by stockholders.
Investors should consider an investment in our common stock as risky and invest only if they can withstand a significant loss and wide fluctuations in the market value of their investment. Investors may be unable to sell their common stock at or above the price they paid for such stock due to fluctuations in the market price of our common stock arising from changes in our operating performance or prospects. Some of the factors that may cause the market price of our common stock to fluctuate or decrease include:
•results and timing of our clinical trials and clinical trials of our competitors’ products;
•failure or discontinuation of any of our development programs;
•the success of our partnerships, including our and Jazz’s ability and efforts to collaborate to develop and commercialize zanidatamab in the territories covered by the Jazz Collaboration Agreement;
•our ability to achieve milestones and receive associated milestone payments pursuant to the terms of our collaboration agreements;
•issues in manufacturing our product candidates or future approved products;
•regulatory developments or enforcement in the United States and foreign countries with respect to our product candidates or our competitors’ products;
•competition from existing products or new products that may emerge;
•developments or disputes concerning patents or other proprietary rights;
•introduction of technological innovations or new commercial products by us or our competitors;
•announcements by us, our strategic partners or our competitors of significant acquisitions, strategic partnerships, joint ventures, or capital commitments;
•changes in estimates or recommendations by securities analysts that cover our common stock;
•fluctuations in the valuation of companies in the biotechnology industry or otherwise perceived by investors to be comparable to us;
•additional instances of stockholder activism, including unsolicited takeover proposals or proxy contests;
•claims or litigation related to our stockholder rights plan;
•public concern over our product candidates or any future approved products;
•litigation;
•future sales of our common stock;
•stock price and volume fluctuations attributable to inconsistent trading volume levels of our common stock;
•additions or departures of key personnel;
•our ability to execute on our key strategic priorities;
•changes in the structure of health care payment systems in the United States or other countries;
•failure of any of our product candidates, if approved, to achieve commercial success;
•economic and other external factors or other disasters or crises, including pandemics;
•period-to-period fluctuations in our financial condition and results of operations, including the timing of receipt of any milestone or other payments under commercialization or licensing agreements;
•general market conditions and market conditions for biopharmaceutical stocks;
•potential disagreements or disputes with certain of our stockholders;
•overall fluctuations in U.S. equity markets; and
•other factors that may be unanticipated or out of our control.
In addition, the stock market in general, and the stock of biopharmaceutical companies in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of the relevant companies, including recently in connection with the COVID-19 pandemic, which has resulted in increased volatility and decreased stock prices for many companies notwithstanding the lack of a fundamental change in their underlying business models or prospects. Broad market and industry factors, including potentially worsening economic conditions and other adverse effects or developments relating to the COVID-19 pandemic, may negatively affect the market price of our common stock, regardless of our actual operating performance. The realization of any of the above risks or any of a broad range of other risks, including those described in this “Risk Factors” section, could have a material adverse effect on the market price of our common stock.
An active trading market for our common stock may not be sustained.
Our common stock was first listed on the NYSE in connection with the completion of the Redomicile Transactions on October 13, 2022. In December 2022, we moved our listing to The Nasdaq Stock Market LLC. There can be no assurance that an active trading market for our common stock will be sustained or continue to be as active or liquid as was the trading market for Zymeworks BC’s common shares prior to the Redomicile Transactions, and the trading price of our common stock may be effectively lower than the trading price of Zymeworks BC’s common shares. If an active market for our common stock does not continue, it may be difficult for our stockholders to sell their stock without depressing the market price for the common stock or sell their common stock at or above the prices at which they acquired their common stock or sell their common stock at the time they would like to sell. Any inactive trading market for our common stock may also impair our ability to raise capital to continue to fund our operations by selling common stock and may impair our ability to acquire other companies or technologies by using our common stock as consideration.
We may fail to meet the continued listing requirements of The Nasdaq Stock Market LLC. If Nasdaq delists our shares of common stock from trading on its exchange, we could face significant material adverse consequences, including:
•significant impairment of the liquidity for our common stock, which may substantially decrease the market price of our common stock;
•a limited availability of market quotations for our securities;
•a determination that our common stock qualifies as a “penny stock” which will require brokers trading in our common stock to adhere to more stringent rules and possibly resulting in a reduced level of trading activity in the secondary trading market for our common stock;
•a limited amount of news and analyst coverage for our company; and
•a decreased ability to issue additional securities or obtain additional financing in the future.
Substantial future sales of our common stock, or the perception that these sales could occur, may cause the price of our common stock to drop significantly, even if our business is performing well.
A large volume of sales of our common stock could decrease the prevailing market price of our common stock and could impair our ability to raise additional capital through the sale of equity securities in the future. Even if a substantial number of sales of our common stock does not occur, the mere perception of the possibility of these sales could depress the market price of our common stock and have a negative effect on our ability to raise capital in the future.
Our management team has broad discretion to use the net proceeds from public and private and debt financings as well as funds received pursuant to our strategic collaborations, and its investment of these proceeds may not yield a favorable return. They may invest the proceeds in ways with which our stockholders disagree.
Our management team has broad discretion in the application of the net proceeds we received pursuant to our January 2022 public offering of common shares and pre-funded warrants to purchase common shares, as well as funds we receive from time to time pursuant to our strategic collaborations and that we may receive from future fundraising efforts, including pursuant to any “at-the-market” equity offering programs we may use from time to time, and we could spend or invest the proceeds in ways with which our stockholders disagree. Accordingly, stockholders will need to rely on our management team’s judgment with respect to the use of these proceeds. However, the failure by management to apply these funds effectively could negatively affect our ability to operate and grow our business.
We cannot specify with certainty all of the particular uses for the net proceeds to be received from our fundraising efforts or for the funds received from time to time pursuant to our strategic collaborations. In addition, the amount, allocation and timing of our actual expenditures will depend upon numerous factors, including additional milestone payments received from our strategic partnerships and royalties received on sale of any future approved product. Accordingly, we will have broad discretion in using these proceeds. Until the net proceeds are used, they may be placed in investments that do not produce significant income or that may lose value.
We do not anticipate paying cash dividends for the foreseeable future, and accordingly, stockholders must rely on stock appreciation for any return on their investment.
We have never paid any dividends on our common stock. We currently intend to retain our future earnings, if any, to fund the development and growth of our business and do not anticipate that we will declare or pay any cash dividends on our common stock in the foreseeable future. As a result, capital appreciation, if any, of our common stock will be the sole source of gain on investment in our common stock for the foreseeable future. Investors seeking cash dividends should not invest in our common stock.
Any future determination to pay dividends will be at the discretion of our board of directors and will depend upon many factors, including our results of operations, financial position, capital requirements, distributable reserves, credit terms, general economic conditions and other factors as our board of directors may deem relevant from time to time. Consequently, future dividends payable to investors are not guaranteed.
Our principal stockholders, in aggregate, could exert substantial influence over us which could delay or prevent a change in corporate control or result in the entrenchment of management or the board of directors.
Our principal stockholders, being our stockholders that beneficially own 5% or more of our common stock, together with their affiliates and related persons, in aggregate, beneficially own approximately 51.4% of our outstanding common stock as of December 31, 2022. Our directors and executive officers beneficially own, in the aggregate, approximately 1.9% of our outstanding common stock as of December 31, 2022. Our principal stockholders, if acting together (with or without our
directors and executive officers), may have the ability to exert substantial influence over the outcome of matters submitted to our stockholders for approval, including the election and removal of directors and any merger or sale of all or substantially all of our assets. In addition, our principal stockholders, if acting together (with or without our directors and executive officers), may have the ability to exert substantial influence over the management and affairs of our company. Accordingly, this concentration of ownership could harm the market price of our common stock by:
•delaying, deferring, or preventing a change in control;
•entrenching our management or the board of directors;
•impeding a merger, takeover, or other business combination involving us; or
•discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of us.
We have recently qualified as a smaller reporting company, and any decision on our part to comply only with certain reduced reporting and disclosure requirements applicable to such companies could make our common stock less attractive to investors.
As a result of our public float (the market value of our common stock held by non-affiliates) as of June 30, 2022, we qualify as a “smaller reporting company,” as defined under the Exchange Act. In addition, we are a “non-accelerated filer” as defined under the Exchange Act. For as long as we continue to be a smaller reporting company or a non-accelerated filer, we may choose to take advantage of exemptions from various reporting requirements applicable to other public companies that are not smaller reporting companies or non-accelerated filers, as applicable, including, but not limited to, an exemption from the requirement that our independent registered public accounting firm attest to the effectiveness of our internal control over financial reporting under Section 404. We have opted not to obtain such attestation from our independent registered public accounting firm in connection with this Annual Report on Form 10-K. This decision may have a detrimental impact on our ability to maintain the adequacy of our internal control over financial reporting, and any failure to maintain adequacy, or inability to produce accurate financial statements or other reports on a timely basis, could increase our operating costs and could materially impair our ability to operate our business.
For so long as we choose to rely on any of these disclosure exemptions, the information we provide stockholders will be different than the information that is available with respect to other public companies. Moreover, if some investors find our common stock less attractive as a result of any choices to reduce our disclosure, there may be a less active trading market for our common stock and the market price of our common stock may be more volatile.
If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results or prevent fraud. As a result, stockholders could lose confidence in our financial and other public reporting, which would harm our business and the trading price of our common stock.
Under the Sarbanes-Oxley Act of 2002, we are required to establish and maintain effective internal control over financial reporting and adequate disclosure controls and procedures. Effective internal control over financial reporting is necessary for us to provide reliable financial reports and, together with adequate disclosure controls and procedures, are designed to prevent fraud. Even if our management concludes that our internal control over financial reporting is effective, our independent registered public accounting firm may conclude that there are material weaknesses with respect to our internal controls or the level at which our internal controls are documented, designed, implemented or reviewed. Undetected material weaknesses in our internal controls could lead to financial statement restatements and require us to incur the expense of remediation.
We have transitioned to a new enterprise resource planning system, which we believe will lead to improvements in our internal control over financial reporting. Although we have completed this transition to a new enterprise resource planning system, the full impact of this transition is not yet known. If, during the evaluation and testing process of our internal controls, we identify one or more material weaknesses in our internal control over financial reporting, we will be unable to assert that our internal control over financial reporting is effective. We cannot assure you that there will not be material weaknesses in our internal controls over financial reporting in the future. If we are unable to conclude that our internal control over financial reporting is effective, or if our independent registered public accounting firm determines we have a material weakness in our internal control over financial reporting, we could lose investor confidence in the accuracy and completeness of our financial reports, the market price of our common stock could decline, and we could be subject to sanctions or investigations by the SEC or other regulatory authorities. Failure to remedy any material weakness in our internal control over financial reporting, or to implement or maintain other effective control systems required of public companies, could also restrict our future access to the capital markets. Furthermore, if we cannot provide reliable financial reports or prevent fraud, including as a result of remote working by our employees, our business and results of operations would likely be materially and adversely affected.
Delaware law and provisions in our amended and restated certificate of incorporation and amended and restated bylaws might delay, discourage or prevent a change in control of Zymeworks or changes in our management, thereby depressing the market price of our common stock.
Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that may make the acquisition of Zymeworks more difficult or delay or prevent changes in control of its management. Among other things, these provisions:
•authorize our board of directors to issue shares of preferred stock and determine the price and other terms of those shares, including preferences and voting rights, without stockholder approval;
•permit only the board of directors to establish the number of directors and fill vacancies and newly created directorships on the board, provided that the board of directors’ ability to increase the size of the board and fill vacancies and newly created directorships will be subject to the restrictions in our amended and restated certificate of incorporation and amended and restated bylaws;
•establish that members of our board of directors serve in one of three staggered terms of three years each;
•provide that our directors may only be removed by the affirmative vote of at least 66 2/3% of the voting power of the shares cast on such proposal;
•permit stockholders to only take actions at a duly called annual or special meeting and not by written consent;
•require that stockholders give advance notice to nominate directors or submit proposals for consideration at stockholder meetings;
•not provide for cumulative voting rights in the election of directors;
•provide that special meetings of Zymeworks’ stockholders may be called only by the board of directors, the chairperson of the board of directors, Zymeworks’ chief executive officer, president or the secretary upon request from holders of no less than 20% of our outstanding voting stock, subject to the limitations and requirements set forth in our amended and restated bylaws; and
•require a super-majority vote of stockholders to amend some of the provisions described above.
In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the DGCL, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with any “interested stockholder” for a period of three years following the date on which the stockholder became an “interested stockholder” unless certain conditions are met.
These provisions, alone or together, could delay, discourage or prevent a transaction involving a change in control of Zymeworks. These provisions could also discourage proxy contests and make it more difficult for stockholders to elect directors of their choosing and to cause Zymeworks to take other corporate actions they desire, any of which, under certain circumstances, could limit the opportunity for our stockholders to receive a premium for their shares of common stock, and could also affect the price that some investors are willing to pay for our common stock.
The stockholders’ rights plan adopted by our board of directors may discourage a third party from acquiring us in a manner that could result in a premium price to our stockholders.
On October 12, 2022, we entered into a Preferred Stock Rights Agreement (the “New Rights Plan”) pursuant to which our board of directors authorized and declared a dividend distribution of one right (each, a “Right”) for each share of our common stock outstanding on October 13, 2022 (the “Record Date”), and for each share of common stock that becomes outstanding between the Record Date and the earlier of the date the Rights become exercisable and the expiration of the Rights. Each Right entitles the registered holder to purchase from us one one-thousandth of a share of our Series B Participating Preferred Stock at an exercise price of $74.00, subject to adjustment. In general terms, the New Rights Plan works by imposing a significant penalty upon any person or group that acquires 10 percent or more (or 20 percent or more in the case of certain institutional investors who report their holdings on Schedule 13G) of the shares of our common stock without the approval of our board of directors. As a result, the overall effect of the New Rights Plan and the issuance of the Rights may be to render more difficult or discourage a merger, amalgamation, arrangement, take-over bid, tender or exchange offer or other business combination involving us that is not approved by our board of directors. However, neither the New Rights Plan nor the Rights should interfere with any merger, amalgamation, arrangement, take-over bid, tender or exchange offer or other business combination approved by the Board. The terms of the New Rights Plan are substantively similar in all material respects to the terms of the
Zymeworks BC Preferred Shares Rights Agreement, which expired in connection with the completion of the Redomicile Transactions.
Our amended and restated bylaws designate a state or federal court located within the State of Delaware as the exclusive forum for substantially all disputes between Zymeworks and its stockholders, and also provide that the federal district courts are the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act, each of which could limit our stockholders’ ability to choose the judicial forum for disputes with Zymeworks or its directors, officers, stockholders or employees.
Our amended and restated bylaws provide that, unless we consent in writing to the selection of an alternative forum, the sole and exclusive forum for (1) any derivative action or proceeding brought on our behalf, (2) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, stockholders, officers or other employees to Zymeworks or our stockholders, (3) any action arising pursuant to any provision of the DGCL, our amended and restated certificate of incorporation or our amended and restated bylaws or (4) any other action asserting a claim that is governed by the internal affairs doctrine shall be the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, another State court in Delaware or the federal district court for the District of Delaware), except for any claim as to which such court determines that there is an indispensable party not subject to the jurisdiction of such court (and the indispensable party does not consent to the personal jurisdiction of such court within ten days following such determination), which is vested in the exclusive jurisdiction of a court or forum other than such court or for which such court does not have subject matter jurisdiction. This provision does not apply to any action brought to enforce a duty or liability created by the Exchange Act and the rules and regulations thereunder.
Section 22 of the Securities Act establishes concurrent jurisdiction for federal and state courts over Securities Act claims. Accordingly, both state and federal courts have jurisdiction to hear such claims. To prevent having to litigate claims in multiple jurisdictions and the threat of inconsistent or contrary rulings by different courts, among other considerations, our amended and restated bylaws provides that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States will be the sole and exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act.
Any person or entity purchasing or otherwise acquiring or holding or owning (or continuing to hold or own) any interest in any of our securities shall be deemed to have notice of and consented to the foregoing bylaw provisions. Although we believe these exclusive forum provisions benefit us by providing increased consistency in the application of Delaware law and federal securities laws in the types of lawsuits to which each applies, the exclusive forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum of its choosing for disputes with us or our current or former directors, officers, stockholders or other employees, which may discourage such lawsuits against us and our current and former directors, officers, stockholders and other employees. Our stockholders will not be deemed to have waived its compliance with the federal securities laws and the rules and regulations thereunder as a result of our exclusive forum provisions.
The enforceability of similar exclusive forum provisions in other companies’ organizational documents have been challenged in legal proceedings, and, while certain courts have determined these provisions are enforceable, it is possible that a court of law could rule that these types of provisions are inapplicable or unenforceable if they are challenged in a proceeding or otherwise. If a court were to find either exclusive forum provision contained in our amended and restated bylaws to be inapplicable or unenforceable in an action, we may incur significant additional costs associated with resolving such action in other jurisdictions, which could harm our financial condition and results of operations.
General Risk Factors
We are at risk of securities class action litigation.
Securities class action litigation has often been brought against companies following a decline in the market price of their securities. This risk is especially relevant for us because biotechnology companies have experienced significant stock price volatility in recent years. If we face such litigation, it could result in substantial costs and a diversion of management’s attention and resources, which could materially harm our business.
If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.
The trading market for our common stock will depend on the research and reports that securities or industry analysts publish about us or our business. We do not have any control over these analysts. We cannot assure that analysts will cover us or provide accurate or favorable coverage. If one or more of the analysts who cover us downgrade our stock or change their opinion of our common stock negatively, our stock price would likely decline. If one or more of these analysts cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our stock price or trading volume to decline. Moreover, the research and reports that analysts publish may suggest a price for our common stock that does not fully or accurately reflect the true value of our company. Furthermore, even if such analyst publications are favorable, these reports could have negative consequences for us.

Management's Discussion and Analysis of Financial Condition and Results of Operations.”
Unless the context otherwise requires or otherwise expressly states, all references in this Annual Report on Form 10-K to “Zymeworks,” the “Company,” “we,” “us” and “our” (i) for periods until completion of the Redomicile Transactions, refer to Zymeworks BC Inc. and its subsidiaries and (ii) for periods after completion of the Redomicile Transactions, refer to Zymeworks Inc. and its subsidiaries.
Overview
Zymeworks is a biotechnology company committed to the discovery, development, and commercialization of novel, multifunctional biotherapeutics. Zymeworks’ mission is to make a meaningful difference for people impacted by difficult-to-treat cancers and other serious diseases. Zymeworks’ complementary therapeutic platforms and fully integrated drug development engine provide the flexibility and compatibility to precisely engineer and develop highly differentiated antibody-based therapeutic candidates.
Our goal is to use our experience and capabilities developing multifunctional therapeutics platforms, along with our proprietary protein engineering capabilities, to have a meaningful and positive impact on the lives of people living with difficult-to-treat cancers and other serious diseases with high unmet medical need.
We commenced operations in 2003 and have since devoted substantially all of our resources to research and development activities including developing our therapeutic platforms, identifying and developing potential product candidates and undertaking preclinical studies and clinical trials. Additionally, we have supported our research and development activities with general and administrative support, as well as by raising capital, conducting business planning and protecting our intellectual property. We have not generated any revenue from the sale of approved products to date and do not expect to do so until such time as we obtain regulatory approval and commercialize one or more of our product candidates. We cannot be certain of the timing or success of approval of our product candidates.
Since our initial public offering (“IPO”) in 2017, we have funded our operations primarily through follow-on public offerings, including the issuance of pre-funded warrants, and payments received under our license and collaboration agreements. Payments received from our license and collaboration agreements include upfront fees, milestone payments, as well as research support and reimbursement payments. Prior to our IPO, we also received financing from private equity placements and the issuance of convertible debt, which was subsequently converted into equity securities, and a credit facility. From inception to December 31, 2022, we received $911.3 million, net of equity issuance costs, from these sources of financing including proceeds from exercises of stock options and employee stock purchase plans. As of December 31, 2022, we had $492.2 million of cash resources consisting of cash, cash equivalents and short-term investments.
Although it is difficult to predict our funding requirements, based upon our current operating plan, we anticipate that our existing cash and cash equivalents and short-term investments as of December 31, 2022, combined with certain anticipated milestone payments from our existing collaborations, will enable us to fund our operating expenditures and capital expenditure requirements for at least the next twelve months from the date this Annual Report on Form 10-K is filed with the SEC.
We reported net income of $124.3 million for the year ended December 31, 2022 and through December 31, 2022, we had an accumulated deficit of $558.8 million. Over the next several years, we expect to continue to incur losses as we increase our research and development expenditures in connection with the ongoing development of our product candidates and other clinical, preclinical and regulatory activities.
Recent Developments
Zanidatamab Clinical Program
In December 2022, we published in The Lancet Oncology our Phase 1 data (NCT02892123) in pre-treated patients with HER2-expressing solid tumors who received zanidatamab monotherapy. Eighty-six patients (22 patients with BTC, 28 patients with CRC and 36 patients with other solid tumors excluding GEA or breast cancer) demonstrated promising responses and zanidatamab was generally well tolerated in patients. Grade 1-2 diarrhea and infusion reactions were the most common reported treatment-related adverse events with no treatment-related deaths. In addition, 31 [37%; 95% CI 27.0, 48.7] of 83 evaluable patients had a cORR.
In December 2022, we presented Phase 2 clinical data at the San Antonio Breast Cancer Symposium. The presentation reported data from a clinical study of 45 patients with heavily pretreated HER2-positive, HR-positive metastatic breast cancer who received zanidatamab in combination with palbociclib and fulvestrant. Patients had received prior regimens containing HER2-targeted agents including trastuzumab (100%), pertuzumab (80%), T-DM1 (98%), and other available options. In 36 efficacy-evaluable patients, treatment with zanidatamab in combination with palbociclib and fulvestrant resulted in a cORR of 33% [95% CI: 18.6, 51.0] and DCR of 92% [95% CI: 77.5, 98.2], and the majority of patients experienced a decrease in tumor size. The mPFS was 9.6 months [95% CI: 7.2, 16.6] with seven patients still on study at the time of data cut-off (August 31, 2022). The regimen was generally well tolerated with expected rates of neutropenia, a known side effect of CDK4/6 inhibitors. The majority of patients with treatment-related adverse events experienced mild to moderate severity (Grade 1 or 2).
Also in December 2022, we announced positive top-line data in the HERIZON-BTC-01 pivotal Phase 2b trial of zanidatamab as monotherapy in previously treated HER2-amplified BTC patients. The top-line results showed that 41.3% [95% CI: 30.4, 52.8] of enrolled patients with HER2-amplified and expressing (IHC2+ and 3+) disease achieved a confirmed objective response as assessed by independent central review. The median duration of response was 12.9 months [95% CI: 5.95 to not reached]. The safety profile of zanidatamab in this trial was consistent with that observed in previously reported monotherapy studies, with no new safety signals identified. Full results from the pivotal trial are expected to be presented at a medical meeting in the first half of 2023.
In January 2023, we presented updated Phase 2 clinical data at the ASCO Gastrointestinal Cancers Symposium. The presentation included updated data from a clinical study evaluating zanidatamab in combination with standard of care chemotherapy in first-line HER2-expressing GEA patients. Patients had not received prior HER2-targeted agents or systemic treatment for metastatic GEA. A total of 46 patients with metastatic GEA were enrolled from 15 sites across the United States, Canada and South Korea. The data demonstrated zanidatamab combined with standard chemotherapy is a highly active treatment regimen for first-line therapy of HER2-positive metastatic GEA. In 42 patients evaluable for OS receiving zanidatamab in combination with chemotherapy, the 18-month OS rate was 84% [95% CI: 68, 93], the 12-month OS rate was 88% [95% CI: 73, 95], and the median OS had not yet been reached (with 26.5 months median duration of study follow-up). These data represent the first OS data presented for a zanidatamab containing regimen. Treatment with zanidatamab resulted in a cORR of 79% [95% CI: 63, 90], a DCR of 92% [95% CI: 79, 98], with three patients achieving complete response among 38 response-evaluable patients. The median duration of response was 20.4 months [95% CI: 8.3, NE] with an mPFS of 12.5 months [95% CI: 7.1, NE] with 17 patients having an ongoing response at the time of data cut-off. The regimen was manageable, tolerable and consistent with the observed safety profiles reported for other standard combination regimens for patients with HER2-positive GEA. Zanidatamab was also recently selected for inclusion in the I-SPY platform trials for patients with HER2-expressing tumors in neoadjuvant treatment of locally advanced breast cancer, which continues to explore the potential use of zanidatamab in indications outside of GEA and BTC.
Zanidatamab Zovodotin Clinical Program
In January 2023, we announced our plans for the continued development of zanidatamab zovodotin at the RP2D of 2.5 mg/kg every three weeks and announced that by the end of 2023, we expect to present additional data from our clinical study that further supports this RP2D. Based on the data generated to date from the Phase 1 clinical study, which has continued to enroll subjects to gather additional data for zanidatamab zovodotin monotherapy, we plan to evaluate zanidatamab zovodotin as monotherapy and/or in combination with the current respective standards of care in multiple planned Phase 2 studies. Based on our development efforts to date and in combination with the results of these planned clinical studies, we believe these results may provide the rationale for one or more registration-enabling studies of zanidatamab zovodotin before the end of 2025, which we would expect to undertake with a future collaboration partner.
Preclinical Programs
As part of our early Research and Development day held in New York City in October 2022, we announced multiple preclinical product candidates, including two lead candidates, ZW191 and ZW171. Our lead ADC preclinical product candidate, ZW191, is a folate receptor alpha targeted ADC with a novel TOPO1i-based payload that we believe may be competitive in areas with high unmet medical need. Similarly, our lead multispecific preclinical product candidate, ZW171, a novel and differentiated MSLN-targeted bispecific T-cell engaging antibody generated utilizing our Azymetric bispecific platform, targets the potential treatment of patients in pancreatic, mesothelioma, ovarian, and other MSLN-expressing cancers. We expect to submit IND applications for ZW191 and ZW171 in 2024.
Licensing and Collaboration Agreements
In October 2022, Zymeworks BC entered into the Jazz Collaboration Agreement with Jazz, under which Jazz will have development and commercialization rights of zanidatamab throughout the world, but excluding existing territories already governed by Zymeworks BC’s November 2018 license and collaboration agreement with BeiGene. Through December 31, 2022, we have received $375 million in proceeds from the Jazz collaboration and are eligible for reimbursement of all ongoing zanidatamab-related costs in accordance with the development plan and budget. We also remain eligible to receive up to an aggregate of $525.0 million in certain regulatory milestones payments and up to an aggregate of $862.5 million in potential commercial milestone payments, for total potential payments of up to $1.76 billion. In addition, we are eligible to receive tiered royalties between 10% and 20% on Jazz’s annual net sales, with customary reductions in specified circumstances, pending regulatory approval of zanidatamab.
Redomicile
Effective October 13, 2022, we became a Delaware corporation following completion of the Redomicile Transactions. As a result, we have continued under the current Zymeworks name and brand, and will continue to maintain significant operations in both Canada and the United States. To effect the Redomicile Transactions, we conducted a share exchange, pursuant to which holders of Zymeworks BC common shares exchanged their Zymeworks BC common shares for shares of common stock of Zymeworks Inc. (formerly known as Zymeworks Delaware Inc.) or, at their election with respect to all or a portion of their Zymeworks BC common shares and subject to applicable eligibility criteria and an overall cap, Exchangeable Shares in the capital of ExchangeCo, a newly formed indirect subsidiary of Zymeworks Inc. A special meeting of Zymeworks BC security holders was held on October 7, 2022 to approve the Redomicile Transactions. The Redomicile Transactions were governed by the Restated and Amended Transaction Agreement, by and among Zymeworks BC, us, CallCo and ExchangeCo, including a plan of arrangement included as Exhibit A to the Restated and Amended Transaction Agreement (the “Plan of Arrangement”). The foregoing description of the Redomicile Transactions is only a summary, does not purport to be complete and is qualified in its entirety by reference to the Restated and Amended Transaction Agreement, including the Plan of Arrangement, a copy of which is included as Exhibit 2.1 to this Annual Report on Form 10-K.
Pursuant to the terms of the Restated and Amended Transaction Agreement, we, Zymeworks BC, CallCo and ExchangeCo agreed, among other things, to use reasonable efforts to take certain corporate steps and actions, as may be necessary or desirable, to effect and implement certain Post-Arrangement Transactions, including the movement of certain subsidiaries of Zymeworks BC so that they become our directly, wholly-owned subsidiaries. Following Zymeworks BC’s entry into the Jazz Collaboration Agreement, we reevaluated the potential impacts of completing the Post-Arrangement Transactions and have determined that completing the Post-Arrangement Transactions as contemplated in the Restated and Amended Transaction Agreement would result in negative tax consequences. As a result, we are evaluating alternatives to the previously contemplated Post-Arrangement Transactions with our advisors.
COVID-19
COVID-19 has impacted our research and development activities but has not caused significant disruptions to our business operations to date. In March 2020, we transitioned our workforce to a remote working arrangement to protect the health and safety of our employees. In June 2020, we implemented a program to facilitate the phased return of employees to our lab and office facilities pursuant to enhanced health and safety protocols consistent with guidelines issued by local health authorities. Our preclinical research activities were supplemented by support from external CROs to complement the temporarily reduced capacity at our lab facilities. Certain clinical trial activities, including patient enrollment and site activations, were delayed or otherwise impacted by COVID-19. To date, COVID-19 has not had a material impact on our financial condition, liquidity or longer-term strategic development and commercialization plans. Recently, President Biden announced that the administration intends to end the COVID-19 national and public health emergencies on May 11, 2023. The full impact of this termination of the public health emergencies on FDA and other regulatory policies and operations are unclear.
The extent to which COVID-19 may cause more significant disruptions to our business and greater impacts to our results of operations will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the location, duration and severity of outbreaks, including potential future waves or cycles, and the effectiveness of actions to contain and treat COVID-19. The COVID-19 pandemic continues to rapidly evolve, and we will continue to monitor the effects of COVID-19 on our business and review our current policies to protect the well-being of our employees and their families in the event of any changes in government restrictions and to ensure the continuity of our operations. See Item 1A, “Risk Factors - Risks Related to Our Business and the Development and Commercialization of Our Product Candidates - Our business has been and may continue to be adversely affected by the COVID-19 pandemic.”
Other Matters
On October 12, 2022, we entered into the New Rights Plan. Under the New Rights Plan, in connection with the consummation of the Redomicile Transactions, our board of directors authorized and declared a dividend distribution of one right (each, a “Right”) for each share of common stock outstanding at 12:01 a.m. (Pacific Time) on the Record Date (October 13, 2022) and for each share of common stock that becomes outstanding, including any shares of common stock issued in connection with the Redomicile Transactions and as consideration for the Exchangeable Shares, as applicable, between the Record Date and the earlier of the distribution date as set forth in the New Rights Plan and the expiration of the Rights. The terms of the New Rights Plan are substantively similar in all material respects to the terms of the Rights Plan. The New Rights Plan is scheduled to expire on June 8, 2023.
On January 3, 2023, we removed Dr. Neil Josephson from the position of Chief Medical Officer.
Financial Operations Overview
Revenue
Our revenue consists of collaboration revenue, including amounts recognized relating to upfront non-refundable payments for licenses or options to obtain future licenses, research and development funding and milestone payments earned under collaboration and license agreements. We expect that collaboration revenue from our strategic partnerships will be our primary source of revenue for the foreseeable future.
Operating Expenses
Our operating expenses consist primarily of research and development expenses and general and administrative expenses. Personnel costs including salaries, benefits, bonuses and stock-based compensation expense, comprise a significant component of research and development and general and administrative expenses. We allocate certain indirect expenses associated with our facilities, information technology, depreciation and other overhead costs between research and development and general and administrative categories based on employee headcount and the nature of work performed by each employee.
Research and Development Expense
Research and development expenses consist of expenses incurred in performing research and development activities such as conducting clinical trials and preclinical research studies, technical and manufacturing operations, regulatory affairs and other indirect expenses in support of advancing our product candidates and therapeutic platforms. Research and development expenses include third-party program costs, internal personnel costs and other indirect costs as follows:
•fees paid to CROs, consultants, subcontractors and other third-party vendors for work performed for our clinical trials, preclinical studies and regulatory activities;
•fees paid to third-party manufacturers to produce our product candidate supplies;
•amounts paid to vendors and suppliers for laboratory supplies;
•fees, milestone payments and other expenses incurred in connection with license agreements and amendments;
•employee-related expenses such as salaries and benefits and stock-based compensation;
•depreciation of laboratory equipment, computers and leasehold improvements; and
•overhead expenses such as facilities, information technology and other allocated items.
It is difficult to determine with certainty the duration and completion costs of our current or future clinical trials and preclinical programs of our product candidates, or if, when or to what extent we will generate revenue from the commercialization and sale of any of our product candidates that obtain regulatory approval. We may never succeed in achieving regulatory approval for any of our product candidates. The duration, costs and timing of clinical trials and development of our product candidates will depend on a variety of factors, including the uncertainties of clinical trials and preclinical studies, uncertainties in clinical trial enrollment rates and significant and changing government regulation. In addition, the probability of success for each product candidate will depend on numerous factors, including competition, manufacturing capability and commercial viability. We will determine which programs to pursue and how much to fund each program in response to the scientific and clinical success of each product candidate, as well as an assessment of each product candidate’s commercial potential. Our research and development expenses are expected to increase in the future as we continue to develop our platforms and product candidates.
General and Administrative Expense
General and administrative expenses consist of salaries, benefits and stock-based compensation costs for employees in our executive, finance, legal, intellectual property, business development, human resources and other support functions, as well as legal and professional fees, business insurance, facilities and information technology costs and other expenses. Our general and administrative expenses may increase in the future as we expand our infrastructure to support our ongoing research and development activities.
Other Income (Expense)
Other income (expense) primarily consists of interest income and foreign exchange gain (loss).
Critical Accounting Policies and Significant Judgments and Estimates
Our management’s discussion and analysis of financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these consolidated financial statements requires us to make estimates, judgments and assumptions that are inherently uncertain that affect the amounts reported in the consolidated financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable. We review and evaluate these estimates on an ongoing basis. These assumptions and estimates form the basis for making judgments about the carrying values of assets and liabilities and amounts that have been recorded as revenue and expenses. Actual results and experiences may differ from these estimates. The results of any material revisions would be reflected in the consolidated financial statements prospectively from the date of the change in estimate.
The full extent to which the COVID-19 pandemic may directly or indirectly impact our business, results of operations and financial condition, including revenues, expenses, clinical trials, research and development costs and employee-related amounts, will depend on future developments that are evolving and highly uncertain, such as the duration and severity of outbreaks, including current and potential future waves or cycles, and the effectiveness of actions taken to contain and treat COVID-19. We considered the potential impact of COVID-19 when making certain estimates and judgments relating to the preparation of our consolidated financial statements. While there was no material impact to our consolidated financial statements as of and for the year ended December 31, 2022, our future assessment of the magnitude and duration of COVID-19, as well as other factors, could result in a material impact to our consolidated financial statements in future reporting periods.
For a summary of our significant accounting policies, see Note 2 to the Consolidated Financial Statements in Part II, Item 8, “Consolidated Financial Statements and Supplementary Data.” We consider the following accounting policies to be critical to an understanding of our financial condition and results of operations because these policies require the most subjective or complex judgments on the part of management in their application. There have been no material changes to our critical accounting policies during the year ended December 31, 2022.
Revenue Recognition
Our revenue consists of amounts earned under research and development license and collaboration agreements with our strategic partners. Promised deliverables within these agreements may include grants of licenses, or options to obtain licenses, to our intellectual property, research and development services, and participation on joint research and/or development committees.
In accordance with Accounting Standards Codification Topic 606, Revenue from Contracts with Customers ("ASC 606"), we recognize revenue when our customer obtains control of promised goods or services, in an amount that reflects the consideration which we expect to receive in exchange for those goods or services. For collaborative arrangements that fall within the scope of ASC 808, Collaborative Arrangements ("ASC 808"), we apply the revenue recognition model under ASC 606 to part or all of the arrangements, when deemed appropriate. For collaboration arrangements within the scope of ASC 808 that contain multiple elements, we determine which elements of the arrangement are within the scope of ASC 808 and which elements are within the scope of ASC 606, which may require application of judgment. To determine revenue recognition for arrangements that we determine are within the scope of Topic 606, we perform the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when or as we satisfy a performance obligation. We only apply the five-step model to contracts when it is probable that we will collect the consideration that we are entitled to in exchange for the goods and services transferred to the customer. If the expectation at contract inception is such that the period between payment by the licensee and the completion of related performance obligations will be one year or less, we assume that the contract does not have a significant financing component.
When applying the revenue recognition criteria of ASC 606 to license and collaboration agreements, management may be required to apply significant judgment when evaluating whether contractual obligations represent distinct performance obligations including understanding the nature and significance of the contractual obligations and their standalone selling prices, determining when performance obligations have been met, assessing the recognition and future reversal of variable consideration, and determining and applying appropriate methods of measuring progress for performance obligations satisfied over time. These judgments are discussed in more detail in the following paragraphs for each type of payment received by us under the terms of the license and collaborations agreements.
Licenses of intellectual property including platform technology access: If the license to our intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, we recognize revenues from non-refundable, upfront fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are not distinct from other promises, we apply judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, upfront fees. We evaluate the measure of progress each reporting period and, if necessary, adjust the related revenue recognition accordingly.
Milestone payments: At the inception of each arrangement that includes research, development or regulatory milestone payments, we evaluate whether the milestones are considered probable of being reached and estimate the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within our control or that of the licensee, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. The transaction price is then allocated to each performance obligation on a relative stand- alone selling price basis, for which we recognize revenue as or when the performance obligations under the contract are satisfied.
At the end of each subsequent reporting period, we re-evaluate the probability of achievement of such development milestones and any related constraint, and if necessary, adjust our estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect license, collaboration and other revenues and earnings in the period of adjustment. The process of successfully achieving the criteria for the milestone payments is highly uncertain. Consequently, there is a significant risk that we may not earn all of the milestone payments from each of our strategic partners. We apply significant judgment when assessing the likelihood of whether milestones are considered probable of being achieved and when allocating the transaction price to each performance obligation for revenue recognition purposes.
Royalties and commercial milestones: For arrangements that include sales-based royalties, including commercial milestone payments based on pre-specified level of sales, we recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). Achievement of these royalties and commercial milestones may solely depend upon performance of the licensee. Since inception to date, we have not recognized any royalty revenue or commercial milestone from any of our out-licensing arrangements.
Research support and other payments: Payments by the licensees in exchange for research activities performed by us on behalf of the licensee are recognized as revenue upon performance of such activities at rates consistent with prevailing market rates. Payments for research supplies provided are recognized as revenue upon delivery of the supplies.
Research and Development Costs and Related Accrued Expenses
Research and development costs are expensed as incurred and include costs that we incur for our own and for our strategic partners’ research and development activities. These costs primarily consist of employee-related expenses, including salaries and benefits, expenses incurred under agreements with CROs on our behalf, costs associated with investigative sites and consultants that conduct our clinical trials, the cost of acquiring and manufacturing clinical trial materials and other allocated expenses, share-based compensation expense, and costs associated with nonclinical activities and regulatory approvals.
Clinical trial expenses represent a significant component of research and development expenses and we outsource a significant portion of these activities to third party contract research organizations. Third-party clinical trial expenses include investigator fees, site costs, clinical research organization costs and other trial-related vendor costs. As part of preparing the consolidated financial statements, we estimate accrued liabilities for services that have been performed by clinical research organizations or investigator sites but have not yet been invoiced to us. When making these estimates, we use operational and contractual information from third party service providers and operational data from internal personnel.
Impairment of Long-Lived Assets
Goodwill and IPR&D assets classified as indefinite-lived are not amortized, but are evaluated for impairment annually or more frequently if impairment indicators arise. IPR&D becomes definite-lived upon the completion or abandonment of the associated research and development efforts. For definite-lived intangible assets, if there is a major event indicating that the carrying value may be impaired, then management will perform an impairment test.
Impairment tests for goodwill and intangibles assets involve considerable use of judgment and require management to make estimates and assumptions. The fair values of reporting units are derived from valuation models, which consider various factors such as discount rates, future earnings and growth rates. Changes in estimates and assumptions can affect the reported value of goodwill and intangible assets.
As at December 31, 2022, we performed a qualitative assessment for our annual impairment test of goodwill after concluding that it was not more likely than not that the fair value of the reporting unit was less than its carrying value. Consequently, the quantitative impairment test was not required. We concluded that there were no impairment indicators related to goodwill or other intangible assets as of December 31, 2022.
Stock-Based Compensation
We recognize stock-based compensation expense on certain stock-based awards granted to employees and members of the board of directors based on their estimated fair values using the Black-Scholes option pricing model. The Black-Scholes option pricing model requires assumptions for various inputs to measure fair value, including expected term of the awards, underlying share price volatility, forfeiture rates, risk-free interest rate and expected dividend yields of our common stock. Management uses judgement to determine the inputs to the Black-Scholes option pricing model and changes in these assumptions could have a material impact to the fair value calculations and the amount and timing of stock-based compensation expense recognized in earnings.

Revenue for 2022 included $375.0 million in upfront fees and a $24.3 million development support payments from Jazz, and a $5.0 million upfront fee from Atreca as well as $8.2 million from our other partners for research and development support under cost sharing arrangements. Revenue for 2021 included $8.0 million from BeiGene for a development milestone, $8.0 million from Janssen for two development milestones, $5.0 million from Iconic for partner revenue and $5.7 million from our partners for research and development support under cost sharing arrangements.
Research and Development Expense
Year Ended December 31,
(dollars in millions) 2022 2021 2020 Change 2022 - 2021
Third-party research and development program expenses:
Clinical development programs:
Zanidatamab $ 117.4 $ 86.8 $ 80.5 $ 30.6 35 %
Zanidatamab zovodotin 4.8 12.7 11.5 (7.9) (62) %

Research and development expense (1)
$ 208.6 $ 199.8 $ 171.2 $ 8.8 4 %
(1) We expect research and development expenditures to increase over time, subject to periodic fluctuations, in line with the advancement, expansion and completion of the clinical development of our product candidates, as well as our ongoing preclinical research activities.
Research and development expense increased by $8.8 million in 2022 compared to 2021. In 2022, research and development expense included a non-cash stock-based compensation expense of $2.4 million comprised of a $3.2 million expense from equity classified awards (2021 - $20.1 million expense) and a $0.8 million recovery related to the non-cash mark-to-market revaluation of certain historical liability classified awards (2021 - $4.6 million recovery). Excluding stock-based compensation expense, research and development expense increased by $21.9 million or 12% in 2022 compared to 2021. The increase related primarily to higher manufacturing expenses of zanidatamab for process performance qualification activities and clinical trial expenses for zanidatamab. These were partially offset by a decrease in expenses related to preclinical activities as well as a decrease in expenses related to clinical activities for zanidatamab zovodotin.
General and Administrative Expense
Year Ended December 31,
2022 2021 2020 Change 2022 - 2021
(dollars in millions)
Salaries and benefits $ 22.6 $ 23.5 $ 18.0 $ (0.9) (4) %
Stock-based compensation expense (recovery) 1.2 (5.6) 16.1 6.8 (121) %
Professional fees, consulting and business insurance 35.6 15.2 11.3 20.4 134 %
Other general and administrative expenses 14.0 9.5 9.8 4.5 47 %
General and administrative expense $ 73.4 $ 42.6 $ 55.2 $ 30.8 72 %
General and administrative expense increased by $30.8 million in 2022 compared to 2021. In 2022, general and administrative expense included a non-cash stock-based compensation expense of $1.2 million comprised of a $4.1 million expense from equity-classified awards (2021 - $18.2 million expense) and a $2.9 million recovery from the non-cash mark-to-market revaluation of certain historical liability-classified awards (2021 - $23.8 million recovery). Excluding stock-based compensation expense, general and administrative expense increased by $24.0 million or 50% in 2022 compared to 2021. This increase was primarily due to an increase in consulting fees and professional fees, including fees incurred in connection with the Jazz Collaboration Agreement, depreciation expenses, and other expenses incurred due to our restructuring program (the “Restructuring”) in 2022, as well as a non-recurring sales tax refund recognized in 2021, which partially offset expenses. The increase in expenses during 2022 were partially offset by a decrease in salaries and benefits expense as a result of a decrease in headcount due to our Restructuring.
Other Income
Year Ended December 31,
2022 2021 2020 Change 2022 - 2021
(dollars in millions)
Other income, net $ 4.7 $ 3.3 $ 7.3 $ 1.4 42 %
Net other income increased by $1.4 million in 2022 compared to 2021. Net other income for 2022 included $3.6 million interest income and a net foreign exchange gain of $1.2 million primarily due to the revaluation of stock option liabilities and certain cash, cash equivalents and investments denominated in Canadian dollars. Net other income for 2021 included interest income of $2.0 million and a net foreign exchange gain of $1.2 million.
Liquidity and Capital Resources
Sources of Liquidity
Since our IPO in 2017, we have funded our operations primarily through follow-on public offerings, including the issuance of pre-funded warrants, as well as from upfront fees, milestone payments, and research support payments generated from our strategic collaborations and licensing agreements.
We completed a public offering on January 27, 2020 pursuant to which we sold (i) 5,824,729 common shares (including the sale of 900,000 common shares to the underwriters upon their full exercise of their over-allotment option) at $46.50 per common shares and (ii) 1,075,271 pre-funded warrants in lieu of common shares at 46.4999 per pre-funded warrant. We received gross proceeds of $320.9 million and net cash proceeds of $300.9 million, after underwriting discounts, commissions and estimated offering expenses.
On January 31, 2022, we completed a public offering pursuant to which we sold (i) 11,035,000 common shares (including the sale of 1,875,000 common shares to the underwriters upon their full exercise of their over-allotment option) at $8.00 per common share and (ii) 3,340,000 pre-funded warrants in lieu of common shares at $7.9999 per pre-funded warrant. We received gross proceeds of $115.0 million and net proceeds were $107.6 million, after underwriting discounts, commissions and estimated offering expenses.
In October 2021, Zymeworks BC amended its Open Market Sale AgreementSM, dated as of November 5, 2019 (as amended, the “Prior Sales Agreement”), with Jefferies LLC (“Jefferies”). The Prior Sales Agreement provided for the offer and sale of Zymeworks BC’s common shares from time to time through Jefferies as its sales agent, subject to the maximum aggregate dollar amount registered pursuant to the applicable prospectus supplement. Sales of common shares through Jefferies, if any, were to be made by any method permitted by law deemed to be an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act. No shares of Zymeworks BC’s common shares were sold under the Prior Sales Agreement prior to its termination in October 2022.
As a result of the Redomicile Transactions, in October 2022, Zymeworks BC and Jefferies mutually terminated the Prior Sales Agreement, and we entered into an Open Market Sale AgreementSM, dated as of October 21, 2022 (the “Sales Agreement”) with Jefferies. Subsequently, on October 26, 2022, we notified Jefferies of our decision to terminate the Sales Agreement, effective as of November 9, 2022. No shares of common stock were sold under the Sales Agreement prior to its termination in November 2022.
In November 2022, we entered into a Sales Agreement, dated as of November 9, 2022 (the “Cantor Sales Agreement”), with Cantor Fitzgerald & Co. (“Cantor”). The Cantor Sales Agreement provides for the offer and sale of our common stock from time to time through Cantor as our sales agent, subject to the maximum aggregate dollar amount registered pursuant to the applicable prospectus supplement. Sales of shares of common stock through Cantor, if any, will be made by any method permitted by law deemed to be an “at-the-market” offering as defined in Rule 415(a)(4) under the Securities Act. As of the date of this Annual Report on Form 10-K, no shares of our common stock have been sold under the Cantor Sales Agreement.
As of December 31, 2022, we had $492.2 million in cash resources consisting of cash, cash equivalents and short-term investments.
Cash Flows
The following table represents a summary of our cash flows for the years ended December 31, 2022, 2021 and 2020:
Year Ended
December 31,
2022 2021 2020
(dollars in millions)
Net cash provided by (used in):
Operating activities $ 144.1 $ (192.5) $ (151.4)
Investing activities (53.8) 144.6 (43.4)
Financing activities 108.6 8.0 309.0
Effect of exchange rate changes on cash and cash equivalents 0.2 (0.3) (0.6)
Net increase (decrease) in cash and cash equivalents $ 199.1 $ (40.2) $ 113.6
Operating Activities
In 2022, we generated net cash of $144.1 million in operating activities compared to $192.5 million used in 2021. The increase in net cash provided by operating activities was primarily due to the Jazz Collaboration Agreement, from which we had received a non-refundable $50.0 million upfront payment following receipt of HSR Clearance and delivery of licenses and technology transfer to Jazz, and then a further payment of $325.0 million following Jazz’s decision to continue the collaboration, both in 2022. This was partially offset by higher clinical trial expenses for zanidatamab and increased drug manufacturing expenses, professional fees as well as severance and other expenses incurred due to our Restructuring.
Investing Activities
Net cash used in investing activities in 2022 is primarily related to purchases, net of redemptions of short-term investments in marketable securities of $40.7 million, cash outflows of $8.1 million for the acquisition of property and equipment as well as leasehold improvement expenses for our new office and lab spaces and $5.0 million for acquisitions of intangible assets, primarily consisting of our new computer system implementation in 2022. Net cash provided by investing activities in 2021 was is primarily related to net redemptions of short-term investments in marketable securities of $157.9 million partially offset by cash outflows of $12.4 million for the acquisition of property and equipment as well as leasehold improvement expenses for our new office and lab spaces.
Financing Activities
Net cash provided by financing activities in 2022 included $107.5 million relating to net proceeds from our January 2022 public offering of equity securities and $0.3 million from stock option exercises and $1.4 million from the issuance of common stock in relation to our employee stock purchase plan. Net cash provided by financing activities in 2021 included net proceeds of $6.4 million from stock option exercises and $2.1 million from the issuance of common stock in relation to our employee stock purchase plan.
Funding Requirements
We have not generated any revenue from approved product sales to date and do not expect to do so until such time as we obtain regulatory approval and commercialize one or more of our product candidates. As we are currently in the clinical and preclinical stages of development, it will be some time before we expect to achieve this, and it is uncertain that we ever will.
We expect that we will continue to increase our operating expenses in connection with ongoing clinical trials and preclinical activities and the development of product candidates in our pipeline. In addition, inflation generally may affect us by increasing our cost of labor and clinical trial expenses. Our funding requirements in the short-term and long-term will consist of the operational, capital, and manufacturing expenditures, a portion of which contain contractual or other obligations including future minimum lease payments under non-cancelable operating leases as presented in note 15 and other commitments and contingencies as presented in note 17 to the annual consolidated financial statements. Because of the inherent risks and uncertainties associated with the development and commercialization of our drug candidates, we are unable to estimate the amounts of capital outflows and operating expenditures associated with our current and anticipated clinical trials and preclinical studies.
Although it is difficult to predict our funding requirements, based on our current operating plan, we anticipate that our existing cash and cash equivalents and short-term investments combined with certain anticipated milestone payments from our existing collaborations will enable us to fund our operating expenses and capital expenditure requirements for at least the next twelve months from the date this Annual Report on Form 10-K is filed with the SEC. We have based these estimates on assumptions and plans which may change and which could impact the magnitude and/or timing of operating expenses, capital expenditures and our cash runway. These estimates include future milestone payments which are dependent upon the successful completion of specified research and development activities by us and our collaborators and are therefore uncertain at this time. The successful development of our product candidates and the achievement of milestones by our strategic partners is uncertain, and therefore we are unable to estimate the actual funds we will require to complete the research, development and commercialization of product candidates. See Item 1A, “Risk Factors - Risks Related to Our Business and the Development and Commercialization of Our Product Candidates” and “Risk Factors - Risks Related to Our Dependence on Third Parties.”
We will need substantial additional funding to support our continuing operations and pursue our long-term business plans. Accordingly, our future funding requirements will depend on many factors, including but not limited to:
•the scope, rate of progress, results and costs of our clinical trials, preclinical studies and other related activities;
•our ability to establish and maintain strategic collaborations, licensing or other arrangements and the financial terms of such agreements as well as our ability to enter into new arrangements;
•the timing and the costs of obtaining regulatory approvals for any of our current or future drug candidates;
•the cost of commercialization activities if any of our current or future drug candidates are approved for sale, including marketing, sales and distribution costs;
•the amount of royalties and sales-based milestones, if any, received from our collaboration partners for commercial sales of drug candidates, should any of such drug candidates receive marketing approval; and
•the amount of revenue, if any, received from commercial sales of our drug candidates, should any of our drug candidates receive marketing approval.
If adequate funds are not available at favorable terms, we may be required to reduce operating expenses, delay or reduce the scope of our product development and commercial expansion programs, obtain funds through arrangements with others that may require us to relinquish rights to certain of our technologies or products that we would otherwise seek to develop or commercialize ourselves or cease operations. If we do raise additional capital through public or private equity or convertible debt offerings, the ownership interest of our existing stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect our stockholders’ rights. If we raise additional capital through debt financing, we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. A deterioration in the equity or credit markets may make any necessary debt or equity financing more difficult, more costly and more dilutive.
Segment Reporting
We view our operations and manage our business in one segment, which is the development of next-generation multifunctional biotherapeutics.
Outstanding Share Data
Our authorized share capital consists of 1,000,000,000 shares of stock, consisting of 900,000,000 shares of common stock, par value $0.00001 per share, and 100,000,000 shares of preferred stock, par value 0.00001 per share. As of March 3, 2023,
64,041,287 shares of common stock were issued and outstanding.

In connection with the Plan of Arrangement, we issued to Computershare Trust Company of Canada, a trust company existing under the laws of Canada (the “Share Trustee”), one share of our preferred stock, par value $0.00001 per share, which has certain variable voting rights in proportion to the number of Exchangeable Shares outstanding (the “Special Voting Preferred Stock”), enabling the Share Trustee to exercise voting rights for the benefit of the Exchangeable Shareholders.
In connection with the consummation of the Plan of Arrangement, 1,424,533 Exchangeable Shares were issued to former Zymeworks BC shareholders. We will issue shares of our common stock as consideration when a holder of Exchangeable Shares calls for Exchangeable Shares to be retracted by ExchangeCo, when ExchangeCo redeems Exchangeable Shares from the holder, or when CallCo purchases Exchangeable Shares from the Exchangeable Shareholder under CallCo’s overriding call rights.
As of March 3, 2023, 765,921 Exchangeable Shares have been exchanged on a one-to-one basis for 765,921 shares of our common stock and 658,612 Exchangeable Shares are held by former Zymeworks BC shareholders and are exchangeable on a one-to-one basis, subject to adjustment, for up to 658,612 shares of our common stock.

Report of Independent Registered Public Accounting Firm
To the Stockholders and Board of Directors
Zymeworks Inc.:
Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated balance sheets of Zymeworks Inc. (the Company) as of December 31, 2022 and 2021, the related consolidated statements of income (loss), comprehensive income (loss), changes in stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2022, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2022, in conformity with U.S. generally accepted accounting principles.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (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 audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. 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 audits, 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. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the consolidated 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 consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Evaluation of distinct performance obligations related to the license and collaboration agreement with Jazz Pharmaceuticals Ireland Limited
As discussed in Note 12 to the consolidated financial statements, the Company entered into a license and collaboration agreement with Jazz Pharmaceuticals Ireland Limited (“Jazz”). The Company recognized upfront consideration of $375.0 million related to the license of intellectual property and $24.3 million related to performance of ongoing clinical research activities during the year ended December 31, 2022. As discussed in Note 2, the accounting for the Company’s contracts with customers arising from licensing and collaboration arrangements requires the Company to apply significant judgment when evaluating whether contractual obligations represent distinct performance obligations, including understanding the nature and significance of the contractual obligations and their standalone selling prices.
We identified the evaluation of distinct performance obligations, including understanding the nature and significance of the contractual obligations and their standalone selling prices, related to the license and collaboration agreement with Jazz as a critical audit matter. Subjective and complex auditor judgment was required to assess the Company’s determination of distinct performance obligations, including evaluating the rights and obligations described in the agreement, their benefit to the customer, and the level of interdependence between the promised goods and services in the agreement. Complex auditor judgment was also required in determining the significance of the contractual obligations to assess if these were immaterial
performance obligations.
The primary procedures we performed to address this critical audit matter included the following. We evaluated the design of an internal control over the Company’s revenue recognition process. This included a control over the Company’s accounting analysis of licensing and collaboration agreements, and the evaluation of distinct performance obligations. We read the license and collaboration agreement with Jazz to gain an understanding of the contractual terms and conditions and the commitments being made in the agreement. We conducted interviews with the Company’s business development personnel to understand the specific functionalities of the license and to evaluate the nature of the commitments made to the customer. We evaluated management’s accounting analysis and assessed the reasonableness of management’s judgments and assumptions in the
determination of distinct performance obligations and the significance of the contractual obligations by comparing them to underlying documentation. We assessed the stand-alone selling price of a selection of certain of the performance obligations used by the Company by comparing them to the Company’s past pricing policies and practices.

ZYMEWORKS INC.
Notes to the Consolidated Financial Statements
(Expressed in thousands of U.S. dollars except share and per share data)
1. Nature of Operations
Zymeworks Inc. (the “Company” or “Zymeworks”) is a clinical-stage biopharmaceutical company dedicated to the development of next-generation multifunctional biotherapeutics. Zymeworks BC Inc. (previously known as "Zymeworks Inc.") was incorporated on September 8, 2003 under the laws of the Canada Business Corporations Act. On October 22, 2003, the Company was registered as an extra-provincial company under the Company Act (British Columbia). On May 2, 2017, the Company continued under the Business Corporations Act (British Columbia).
Since its inception, the Company has devoted substantially all of its resources to research and development activities, including developing its therapeutic platforms and identifying and developing potential product candidates by undertaking preclinical studies and clinical trials. The Company supports these activities through general and administrative support, as well as by raising capital, conducting business planning and protecting its intellectual property.
On July 15, 2022, the Company announced its intention to become a Delaware corporation, subject to receipt of necessary shareholder, stock exchange, and court approvals (the "Redomicile Transactions"). The Redomicile Transactions were completed on October 13, 2022. On October 13, 2022, the Company changed its name to Zymeworks BC Inc. Unless the context otherwise requires or otherwise expressly states, all references in the accompanying consolidated financial statements to “Zymeworks,” the “Company,” “we,” “us” and “our” (i) for periods until completion of the Redomicile Transactions, refer to Zymeworks BC Inc. and its subsidiaries and (ii) for periods after completion of the Redomicile Transactions, refer to Zymeworks Inc. (formerly known as Zymeworks Delaware Inc.) and its subsidiaries.
To effect the Redomicile Transactions, the Company conducted a share exchange, pursuant to which holders of the Company's common shares exchanged their common shares in the Company for shares of common stock of Zymeworks Inc. (formerly known as Zymeworks Delaware Inc.) or, at their election with respect to all or a portion of their common shares in the Company and subject to applicable eligibility criteria and an overall cap, exchangeable shares (the “Exchangeable Shares”) in the capital of a newly formed indirect subsidiary of Zymeworks Inc. A special meeting of Company security holders was held on October 7, 2022 to approve the Redomicile Transactions. The Redomicile Transactions were governed by a transaction agreement dated July 14, 2022, as restated and amended on August 18, 2022 (the “Restated and Amended Transaction Agreement”), by and among the Company and its direct or indirect subsidiaries Zymeworks Inc., Zymeworks CallCo ULC and Zymeworks ExchangeCo Ltd., including a plan of arrangement included as Exhibit A to the Restated and Amended Transaction Agreement (the “Plan of Arrangement”).
2. Summary of Significant Accounting Policies
Basis of Presentation
The consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). The consolidated financial statements include the accounts of Zymeworks Inc. and its wholly owned subsidiaries, Zymeworks BC Inc., Zymeworks Biopharmaceuticals Inc., Zymeworks Pharmaceuticals Limited (Ireland), Zymeworks CallCo ULC, Zymeworks ExchangeCo Ltd., Zymeworks Management Inc. (including this entity's branch in the United Kingdom) and Zymeworks Zanidatamab Inc. All inter-company accounts and transactions have been eliminated on consolidation.
All amounts expressed in the consolidated financial statements of the Company and the accompanying notes thereto are expressed in thousands of U.S. dollars, except for share and per share data and where otherwise indicated. References to “$” are to U.S. dollars and references to “C$” are to Canadian dollars.
Foreign Currency
The functional currency of the Company is the U.S. dollar. Transactions denominated in foreign currencies are translated at the approximate exchange rate prevailing on the date of the transaction. At period end, monetary assets and liabilities denominated in foreign currencies are translated into U.S. dollars using exchange rates in effect at the balance sheet date. Resulting foreign exchange gains and losses are reflected in the Consolidated Statements of Income (Loss) and Comprehensive Income (Loss).
Use of Estimates
The preparation of consolidated financial statements in accordance with U.S. GAAP requires the Company to make estimates and judgments in certain circumstances that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, the Company evaluates its estimates, most notably those related to revenue recognition including estimated timing of completion of performance obligations required to meet revenue recognition criteria, accrual of expenses including clinical and preclinical study expense accruals, stock-based compensation, valuation allowance for deferred taxes, benefits under the Scientific Research and Experimental Development (“SR&ED”) program, and other contingencies. Management bases its estimates on historical experience and on various other assumptions that it believes to be reasonable under the circumstances. Actual results could differ from these estimates.
Revenue Recognition
Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (“ASC 606”) applies to all contracts with customers, except for contracts that are within the scope of other standards, such as leases, insurance, collaboration arrangements and financial instruments. In accordance with ASC 606, the Company recognizes revenue when the Company’s customer obtains control of promised goods or services, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services.
The Company applied ASC 606 to all revenue arrangements to date. For collaborative arrangements that fall within the scope of ASC 808, Collaborative Arrangements (“ASC 808”), the Company applies the revenue recognition model under ASC 606 to part or all of the arrangements, when deemed appropriate.
In accordance with ASC 606, the Company recognizes revenue when the Company’s customer obtains control of promised goods or services, in an amount that reflects the consideration that the Company expects to receive in exchange for those goods or services. In determining the appropriate amount of revenue to be recognized as it fulfills its obligations under each of its agreements, the Company performs the following steps: (i) identification of the promised deliverables in the contract; (ii) determination of whether the promised deliverables are performance obligations including whether they are distinct; (iii) measurement of the transaction price, including uncertainties related to variable consideration; (iv) allocation of the transaction price to the performance obligations based on the stand-alone selling prices; and (v) recognition of revenue when or as the Company satisfies each performance obligation.
The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration that it is entitled to in exchange for the goods and services transferred to the customer. At contract inception, the Company assesses the goods or services promised within each contract that falls under the scope of Topic 606, to identify distinct performance obligations. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when or as the performance obligation is satisfied.
The Company has entered into a number of collaboration and licensing agreements. Promised deliverables within these agreements may include: (i) grants of licenses, or options to obtain licenses, to the Company’s intellectual property, (ii) research and development services, (iii) drug product manufacturing, and (iv) participation on joint research and/or development committees. The terms of these agreements typically include one or more of the following types of payments to the Company:
•non-refundable, upfront license and platform technology access fees;
•research, development and regulatory milestone payments;
•research support, development and other payments; and
•royalties and commercial milestone payments.
If the expectation at contract inception is such that the period between payment by the licensee and the completion of related performance obligations will be one year or less, the Company assumes that the contract does not have a significant financing component.
When applying the revenue recognition criteria of ASC 606 to license and collaboration agreements, the Company may be required to apply significant judgment when evaluating whether contractual obligations represent distinct performance obligations including understanding the nature and significance of the contractual obligations and their standalone selling prices, determining when performance obligations have been met, assessing the recognition and future reversal of variable consideration, and determining and applying appropriate methods of measuring progress for performance obligations satisfied
over time. These judgments are discussed in more detail in the following paragraphs for each type of payment received by the Company under the terms of the license and collaborations agreements.
Non-refundable, upfront license and platform technology access fees
If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenue from non-refundable, upfront fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are not distinct from other promises, the Company uses judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, upfront fees. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the related revenue recognition accordingly.
Research, development and regulatory milestone payments
At the inception of each arrangement that includes research, development or regulatory milestone payments, the Company evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price using the most likely amount method. When it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within the control of the Company or the licensee, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. The transaction price is then allocated to each performance obligation on a relative stand-alone selling price basis, for which the Company recognizes revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, the Company re-evaluates the probability of achievement of such development milestones and any related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect license, collaboration and other revenues and earnings in the period of adjustment. The probability of successfully achieving the criteria for the milestone payments is highly uncertain. Consequently, there is a significant risk that the Company may not earn all of the milestone payments from each of its strategic partners.
Research and development milestones in the Company’s collaboration agreements may include some, but not necessarily all, of the following types of events:
• completion of preclinical research and development work leading to selection of product candidates;
• initiation of Phase 1, Phase 2 and Phase 3 clinical trials; and
• achievement of certain other technical, scientific or development criteria.
Regulatory milestone payments may include the following types of events:
• filing of regulatory applications for marketing approval in the United States, Europe or Japan, including Investigational New Drug (“IND”) applications and Biologics License Application (“BLA”); and
• marketing approval in major markets, such as the United States, Europe or Japan.
Research support, development and other payments
Payments by the licensees in exchange for research and development activities performed by the Company on behalf of the licensee are recognized as revenue upon performance of such activities at rates consistent with prevailing market rates. Payments for research and development supplies provided are recognized as revenue upon delivery of the supplies.
Royalties and commercial milestone payments
For arrangements that include sales-based royalties, including commercial milestone payments based on pre-specified level of sales, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). Achievement of these royalties and commercial milestones may solely depend upon performance of the licensee.
Contract assets and liabilities
Contract assets are mainly comprised of trade receivables net of expected credit losses, which includes amounts billed and currently due from customers.
Contract liabilities are mainly comprised of deferred revenues. Amounts received prior to satisfying all revenue recognition criteria are recorded as deferred revenue in the Company’s consolidated financial statements. Amounts not expected to be recognized as revenue within the next twelve months of the consolidated balance sheet date are classified as long-term deferred revenue.
Cash and Cash Equivalents
The Company considers all highly liquid investments purchased with original maturities of 90 days or less at the date of acquisition to be cash equivalents. Cash equivalents are recorded at cost plus accrued interest.
Investments
The Company’s short-term and long-term investments include guaranteed investment certificates and term deposits with original maturities exceeding three months. These investments are recorded at cost plus accrued interest, which approximates their fair value.
The Company also holds a limited number of equity securities in private entities which are accounted for as available for sale financial instruments with changes in fair value recorded through other comprehensive income or at cost subject to impairment (note 5).
Accounts Receivable and Expected Credit Losses
Accounts receivable are recorded at invoiced amounts, net of any allowance for doubtful accounts. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in existing accounts receivable.
The Company evaluates the collectability of accounts receivable on a regular basis based upon various factors including the financial condition and payment history of customers, an overall review of collections experience on other accounts and economic factors or events expected to affect future collections experience. Expected credit losses on our accounts receivable were immaterial as at December 31, 2022 and 2021.
Deferred Financing Fees
Deferred financing fees consist of amounts charged by underwriters, attorneys, accountants and printers that are directly attributable to future financing transactions. These costs are deferred and subsequently charged against the gross proceeds of the related financing transaction upon closing of such transaction.
Segment Information
The Company operates and manages its business in one segment, which is the discovery, development and commercialization of next-generation multifunctional biotherapeutics. Operating segments are defined as components of an enterprise about which separate discrete information is available for the chief operating decision maker, or decision making group, in deciding how to allocate resources and assessing performance.
Property and Equipment
Property and equipment are recorded at cost net of accumulated depreciation. Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized in earnings. Repairs and maintenance costs are expensed as incurred.
The Company records depreciation using the straight-line method over the estimated useful lives of the property and equipment as follows:
Asset Class Rate
Computer hardware 3 years
Office equipment 3 years
Furniture and fixtures 5 years
Laboratory equipment 7 years
Leasehold improvements Shorter of the initial lease term or useful life
Property and equipment acquired or disposed of during the year are depreciated proportionately for the period they are in use.
Leases
The Company accounts for leases in accordance with ASC 842 "Leases" ("ASC 842"). The Company determines if an arrangement contains a lease at inception. Right-of-use ("ROU") assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from that lease. For leases with a term greater than 12 months, ROU assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. The lease term includes the option to extend the lease when it is reasonably certain the Company will exercise that option. When available, the Company uses the rate implicit in the lease to discount lease payments to present value. In the case the implicit rate is not available, the Company uses its incremental borrowing rate based on information available at the lease commencement date, to determine the present value of lease payments.
Patents and Intellectual Property Costs
Costs incurred to acquire patents and to prosecute and maintain intellectual property rights are expensed as incurred to general and administrative expense due to the uncertainty surrounding the drug development process and the uncertainty of future benefits. Patents and intellectual property acquired from third parties are capitalized and amortized over the remaining life of the patent, if related to approved products or if there are alternative future uses for the underlying technology. No patent or intellectual property costs have been capitalized to date.
Impairment of Long-Lived Assets
The Company assesses the recoverability of its long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of the long-lived asset is measured by a comparison of the carrying amount of the asset to future undiscounted net cash flows expected to be generated by the asset or group of assets. If carrying value exceeds the sum of undiscounted cash flows, the Company then determines the fair value of the underlying asset. Any impairment to be recognized is measured by the amount by which the carrying amount of the asset group exceeds the estimated fair value of the asset or asset group. As of December 31, 2022 and 2021, the Company determined that there were no indicators of impairment of long-lived assets.
Government Grants and Credits
Government grants are recognized where there is reasonable assurance that the grant will be received and all associated conditions will be complied with. Reimbursements of eligible research and development expenditures pursuant to government assistance programs are recorded as reductions of research and development costs when the related costs have been incurred and there is reasonable assurance regarding collection of the claim.
Grant claims not settled by the balance sheet date are recorded as receivables, provided their receipt is probable. The determination of the amount of the claim, and hence the receivable amount, requires management to make calculations based on its interpretation of eligible expenditures in accordance with the terms of the programs. The reimbursement claims submitted by the Company are subject to review by the relevant government agencies. The Company has used its best judgment and understanding of the related program agreements in determining the receivable amount.
The Company participates in SR&ED and Research Tax Credit Programs, two federal tax incentive programs that encourage Canadian and U.S. businesses to conduct research and development in Canada and in United States, respectively. The benefits of investment tax credits for scientific research and development expenditures are recognized in the year the qualifying
expenditure is made provided there is reasonable assurance of recoverability. The refundable portion of investment tax credits are recorded as reductions to research and development expenditures.
The Company also participated in the Canada Emergency Wage Subsidy (“CEWS”) and Canada Emergency Rent Subsidy (“CERS”) programs announced by the Government of Canada in April 2020, in order to help employers keep and/or return Canadian-based employees to payrolls in response to challenges posed by the COVID-19 pandemic. The Company recognized CEWS and CERS grants when it is probable that it complied with relevant eligibility requirements and conditions of the grant and that the grant would be received. These grants are recorded as reductions to wage and rent expenditures.
Research and Development Costs
Research and development costs are expensed as incurred and include costs that the Company incurs for its own and for the Company’s strategic partners’ research and development activities. These costs primarily consist of expenses incurred under agreements with contract research organizations on the Company’s behalf, investigative sites and consultants that conduct the Company’s clinical trials, the cost of acquiring and manufacturing clinical trial materials and other allocated expenses, the cost of acquired research patents and intellectual property that do not meet the requirements for capitalization, employee related expenses, including salaries and benefits, stock-based compensation expense, and costs associated with nonclinical activities and regulatory approvals.
Clinical Trial Expense Accruals
Clinical trial expenses represent a significant component of research and development expenses and the Company outsources a significant portion of these activities to third party contract research organizations. Third-party clinical trial expenses include investigator fees, site costs, clinical research organization costs and other trial-related vendor costs. As part of preparing the consolidated financial statements, the Company estimates accrued liabilities for services that have been performed by clinical research organizations or investigator sites but have not yet been invoiced to the Company. When making these estimates, the Company uses operational and contractual information from third party service providers and operational data from internal personnel.
Income Taxes
The Company accounts for income taxes using an asset and liability method. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The measurement of deferred tax assets is reduced, if necessary, by the extent of a valuation allowance. The recognition of uncertain tax positions is evaluated based on whether it is considered more likely than not that the position taken, or expected to be taken, on a tax return will be sustained upon examination through litigation or appeal. For those positions that meet the recognition criteria, they are measured as the largest amount that is more than 50% likely to be realized upon ultimate settlement.
Stock-Based Compensation
The Company recognizes stock-based compensation expense on equity and liability classified stock-based awards granted to employees, directors, and certain consultants. The Company measures the cost of such awards based on the fair value of the award, net of estimated forfeitures, and recognizes stock-based compensation expense in the consolidated statements of income (loss) and comprehensive income (loss) on a straight-line basis over the requisite service period. The requisite service period generally equals the vesting period of the awards. The fair values of stock option awards are estimated using the Black-Scholes option pricing model which uses various inputs including estimated fair value of the Company’s underlying common stock at the grant date, expected term, estimated volatility, risk-free interest rate and expected dividend yields of the Company’s common stock. The Company applies an estimated forfeiture rate derived from historical employee termination behavior. If the actual number of forfeitures differs from those estimated by management, adjustments to compensation expense may be required in future periods. The fair value of restricted stock units (“RSU”) is measured using the per share fair value of the Company’s common stock on the dates of grant.
Equity classified awards are measured using their grant date fair value. Liability classified awards are initially measured using their grant date fair value and are subsequently remeasured at fair value at each balance sheet date until exercised or cancelled, with changes in fair value recognized as compensation cost (ASC 718 awards) or other income and expenses (ASC 815 awards) for the period, while fair value changes below the grant date fair value of the original awards are recorded in additional paid-in capital.
ASC 718 “Compensation-Stock Options” (“ASC 718”), with an exercise price which is not denominated in: (a) the currency of a market in which a substantial portion of the Company’s equity securities trades, (b) the currency in which the individual’s pay is denominated, or (c) the Company’s functional currency, are required to be classified as liabilities. For awards accounted for under ASC 815 “Derivatives and Hedging” (“ASC 815”), any warrant or option that provides for an exercise price which is not denominated in the Company’s functional currency is required to be classified as a liability. Certain option awards which were classified as equity on grant dates were subsequently reclassified to liability upon the change of the compensation currency for certain executives and employees holding these option awards from Canadian dollars to U.S. dollars. Total fair value of these options on reclassification date were recorded as liability awards. Accumulated expense amount to the reclassification date was reversed from additional paid-in capital and the remaining amount was recorded to the statement of loss on reclassification date.
The Company has an employee stock purchase plan which is considered compensatory. Accordingly, the Company recognizes compensation expense on these awards based on their estimated grant date fair value using the Black-Scholes option pricing model. The Company recognizes compensation expense in the consolidated statements of loss and comprehensive loss on a straight-line basis over the requisite service period.
Business Combinations and Goodwill
Business combinations are accounted for using the acquisition method. The fair value of total purchase consideration is allocated to the fair values of identifiable tangible and intangible assets acquired and liabilities assumed, with the remaining amount being classified as goodwill. All assets, liabilities and contingent liabilities acquired or assumed in a business combination are recorded at their fair values at the date of acquisition. If the Company’s interest in the fair value of the acquiree’s net identifiable assets exceeds the cost of the acquisition, the excess is recognized in earnings or loss immediately. Transaction costs that are incurred in connection with a business combination, other than costs associated with the issuance of debt or equity securities, are expensed as incurred.
Goodwill is evaluated for impairment on an annual basis or more frequently if an indicator of impairment is present (note 6). As part of the impairment evaluation, the Company may elect to perform an assessment of qualitative factors. If this qualitative assessment indicates that it is more likely than not that the fair value of the reporting unit that includes the goodwill is less than its carrying value, then a quantitative impairment test would be prepared to compare the fair value to the carrying value and record an impairment charge if the carrying value exceeds the fair value.
Acquired In-Process Research and Development (IPR&D) and Definite-lived Intangible Assets
Acquired IPR&D represents the fair value assigned to research and development assets that have not reached technological feasibility. IPR&D is classified as an indefinite-lived intangible asset and is not amortized. IPR&D becomes definite-lived upon the completion or abandonment of the associated research and development efforts. All research and development costs incurred subsequent to the acquisition of IPR&D are expensed as incurred. Indefinite-lived intangible assets are evaluated for impairment on an annual basis or more frequently if an indicator of impairment is present.
Definite-lived intangible assets include computer software and a research license and are amortized on a basis which reflects the pattern in which the economic benefits are consumed. Amortization begins when the assets are put into use. If there is an event indicating that the carrying value of a definite-lived intangible asset may be impaired, then the Company will perform an impairment test. When an impairment test is performed, if the carrying value exceeds the recoverable value, based on the sum of undiscounted future cash flows, then such asset is written down to its fair value.
The Company records amortization using the straight-line method over the estimated useful lives of the definite-lived intangible assets as follows:
Asset Class Rate
Software 3 years
Licensing agreements Shorter of the licensing term or useful life
Net income (loss) per share
Basic net income (loss) per share attributable to common stockholders is computed by dividing the net income (loss) attributable to common stockholders by the weighted average number of shares of common stock outstanding for the year. Diluted net income (loss) per share attributable to common stockholders is computed by adjusting net income (loss) attributable
to common stockholders to reallocate undistributed earnings based on the potential impact of dilutive securities, including outstanding stock options and warrants. Diluted net income (loss) per share attributable to common stockholders is computed by dividing the diluted net income (loss) attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the year, including potential dilutive shares of common stock assuming the dilutive effect of outstanding instruments. The treasury stock method is used to determine the dilutive effect of the Company’s stock option grants and warrants. ASC 260 “Earnings Per Share” requires an adjustment to the numerator for any income or loss related to liability classified warrants and stock options, if dilutive, if they are presumed to be share settled.

5. Investments
Short-term Investments
Short-term investments are denominated in U.S. dollars or Canadian dollars and consist of guaranteed investment certificates (“GICs”) acquired from financial institutions in accordance with the Company’s cash investment policy. Short-term GICs are classified as held to maturity and available for sale and are accounted for at amortized cost or at fair value.
Long-term Investments
Long-term investments at December 31, 2022 consist of equity securities of $886 acquired for strategic purposes or in connection with licensing and collaboration agreements (December 31, 2021 - $886 which included both equity and debt securities).
6. IPR&D and Goodwill
Acquired IPR&D
In-process research and development assets (“IPR&D”) acquired in the 2016 Kairos Therapeutics Inc. (“Kairos”) business combination are classified as indefinite-lived intangible assets and are not currently being amortized. The following table summarizes the carrying value of IPR&D, net of impairment:
Acquired
IPR&D Accumulated

Change during the period - - -
Balance at December 31, 2022 $ 20,700 $ (3,072) $ 17,628
For the years ended December 31, 2022, December 31, 2021 and December 31, 2020, the Company did not record any impairment charge related to the fair value of IPR&D. The Company performed a qualitative test and concluded that IPR&D was not impaired as of December 31, 2022.
Goodwill
The Company performed its annual impairment test of goodwill as of December 31, 2022 and concluded that no impairment existed. As part of the evaluation of the recoverability of goodwill, the Company identified only one reporting unit to which the total carrying amount of goodwill has been assigned. As at December 31, 2022, the Company performed a qualitative assessment for its annual impairment test of goodwill after concluding that it was not more likely than not that the fair value of the reporting unit was less than its carrying value. Consequently, the quantitative impairment test was not required.

Net proceeds were $107,534, after underwriting discounts, commissions and offering expenses.
b.Authorized Share Capital and Preferred Stock
The Company’s authorized share capital consists of 1,000,000,000 shares of stock, consisting of (i) 900,000,000 shares of common stock, par value $0.00001 per share, and (ii) 100,000,000 shares of preferred stock, par value $0.00001 per share.
In connection with the Plan of Arrangement, we issued to Computershare Trust Company of Canada, a trust company existing under the laws of Canada (the “Share Trustee”), one share of our preferred stock, par value $0.00001 per share, which has certain variable voting rights in proportion to the number of Exchangeable Shares outstanding (the “Special Voting Preferred Stock”), enabling the Share Trustee to exercise voting rights for the benefit of the Exchangeable Shareholders.
Immediately prior to the completion of the Redomicile Transactions, there were 61,699,387 Zymeworks BC Inc. common shares issued and outstanding. In connection with the consummation of the Plan of Arrangement, 60,274,854 shares of Common Stock and 1,424,533 Exchangeable Shares were issued to former Zymeworks BC shareholders. As of December 31, 2022, there were 1,424,533 Exchangeable Shares outstanding. We will issue shares of our common stock as consideration when a holder of Exchangeable Shares calls for Exchangeable Shares to be retracted by ExchangeCo, when ExchangeCo redeems Exchangeable Shares from the holder, or when CallCo purchases Exchangeable Shares from the Exchangeable Shareholder under CallCo’s overriding call rights. These Exchangeable Shares and the Special Voting Preferred Stock, when taken together, are similar in substance to the Company’s common stock.
c.Pre-Funded Common Share Warrants
In connection with a public offering completed on June 24, 2019, the Company issued 4,166,690 pre-funded warrants at a price of $17.9999 per pre-funded warrant which granted holders of warrants the right to purchase up to 4,166,690 common shares of the Company, at an exercise price of $0.0001 per share.
In connection with a public offering completed on January 27, 2020 (note 10a), the Company issued 1,075,271 pre-funded warrants at a price of $46.4999 per pre-funded warrant which granted holders of warrants the right to purchase up to 1,075,271 common shares of the Company, at an exercise price of $0.0001 per share.
In connection with a public offering completed on January 31, 2022 (note 10a), the Company issued 3,340,000 pre-funded warrants at a price of $7.9999 per pre-funded warrant which granted holders of warrants the right to purchase up to 3,340,000 common shares of the Company, at an exercise price of $0.0001 per share.
The pre-funded warrants are exercisable by the holders at any time on or after the original issue date. The pre-funded warrants do not expire unless they are exercised or settled in accordance with the pre-funded warrant agreement. As the pre-funded warrants meet the condition for equity classification, proceeds from issuance of the pre-funded warrants, net of any transaction costs, are recorded in additional paid-in capital. Upon exercise of the pre-funded warrants, the historical costs recorded in additional paid-in capital along with exercise price collected from holders will be recorded in common shares.
On August 23, 2022, 3,787,737 pre-funded warrants were exercised in a cashless transaction in exchange for issuance of 3,787,675 common shares upon which $57,858 has been transferred to common shares account from additional paid-in capital. On October 25, 2022, the Company issued an aggregate of 1,375,000 common shares, to a warrant holder upon the exercise of 1,375,000 pre-funded warrants. On October 27, 2022, the Company issued an additional 1,340,000 common shares to the same
warrant holder upon the exercise of 1,340,000 pre-funded warrants. Each pre-funded warrant had an exercise price of $0.0001 per share of Common Stock.
d.Adoption of a Shareholder Rights Plan
On June 9, 2022, the board of directors authorized and declared a dividend distribution of one right (each, a “Right”) for each outstanding common share of the Company to shareholders of record as of the close of business on June 21, 2022. Each Right entitles the registered holder to purchase from the Company one one-thousandth of a share of Series A Participating Preferred Share, of the Company, at an exercise price of $74.00, subject to adjustment. The complete terms of the Rights are set forth in a Preferred Shares Rights Agreement (the “Rights Plan”), dated as of June 9, 2022, between the Company and Computershare Trust Company, N.A., as rights agent.
In general terms, the Rights Plan works by imposing a significant penalty upon any person or group that acquires 10 percent or more (or 20 percent or more in the case of certain institutional investors who report their holdings on Schedule 13G) of the common shares without the approval of the board of directors. As a result, the overall effect of the Rights Plan and the issuance of the Rights may be to render more difficult or discourage a merger, amalgamation, arrangement, take-over bid, tender or exchange offer or other business combination involving the Company that is not approved by the board of directors. However, neither the Rights Plan nor the Rights should interfere with any merger, amalgamation, arrangement, take-over bid, tender or exchange offer or other business combination approved by the board of directors. The issuance of Rights does not affect reported earnings per share.
On October 12, 2022, Zymeworks Inc. (a Delaware corporation) and Computershare Trust Company, N.A., as rights agent, entered into a Preferred Stock Rights Agreement (the “New Rights Plan”) and on October 13, 2022, the board of directors of Zymeworks Inc. (a Delaware corporation) declared a dividend distribution of one right (each, a “Right”) for each share of common stock outstanding at 12:01 a.m. (Pacific Time) on October 13, 2022 (the “Record Date”) and for each share of common stock that becomes outstanding, including any shares of common stock issued in connection with the Redomicile Transactions and as consideration for the Exchangeable Shares, as applicable, between the Record Date and the earlier of the Distribution Date (as defined in the New Rights Plan) and the expiration of the Rights. On October 13, 2022, the Rights Plan expired. The New Rights Plan has substantively similar terms as the Rights Plan.
e.Stock-Based Compensation
In connection with the Redomicile Transactions, Zymeworks BC Inc. assigned to the Company, and the Company assumed, all of Zymeworks BC Inc.’s rights and obligations under each of the stock-based compensation plans, as described below, and such plans became the Company’s stock-based compensation plans, with each outstanding award assumed by the Company and deemed exchanged for equivalent awards of the Company, except that the security issuable upon exercise or settlement, as applicable, will be shares of common stock of the Company rather than common shares of Zymeworks BC Inc.
Original Stock Option Plan
On July 14, 2006, the shareholders of the Company approved an employee stock option plan (the “Original Plan”). The Original Plan provides for the granting of options to directors, officers, employees and consultants. Options to purchase common shares may be granted at an exercise price of each option equal to the last private issuance of common shares immediately preceding the date of the grant. The total number of options outstanding is not to exceed 20% of the issued common shares of the Company.
Options granted under the Original Plan are exercisable at various dates over their 10-year life. Common shares are issued from treasury when options are exercised.
The exercise prices of the Company’s stock options under the Original Plan are denominated in Canadian dollars. The Canadian dollar amounts have been translated to U.S. dollars using the period end rate or the average foreign exchange rate for the period, as applicable, and have been provided for information purposes. Upon the effectiveness of the Company’s New Stock Option Plan described below, no further options were issuable under the Original Plan. However, all outstanding options granted under the Original Plan remain outstanding, subject to the terms of the Original Plan and the applicable grant documents, until such outstanding options are exercised or they terminate or expire by their terms.
New Plan and Inducement Plan
On April 10, 2017, the Company’s shareholders approved a new stock option plan, which became effective immediately prior to the consummation of the Company’s initial public offering (“IPO”). This plan allows for the grant of options to directors, officers, employees and consultants in U.S. or Canadian dollars, and also permitted the Company to grant incentive stock options (“ISOs”), within the meaning of Section 422 of the Internal Revenue Code, to its employees, until the shares reserved for issuance of ISOs were depleted. On June 7, 2018, the Company’s shareholders approved an amendment and restatement of this plan (this plan, as amended and restated, the “New Plan”), which includes an article that allows the Company to grant restricted shares, restricted share units (“RSUs”) and other share-based awards, in addition to stock options. On March 4, 2020, the board of directors approved certain minor amendments to the New Plan that did not require shareholder approval.
The original maximum number of common shares reserved for issuance under the New Plan as of June 7, 2018 was 5,686,097, which includes 3,686,097 shares issuable upon exercise of options outstanding as of March 31, 2018. Beginning in 2019 and ending in 2028, this maximum number may be increased on the first day of each calendar year by up to 4.0% of the number of outstanding shares on the last day of the immediately preceding calendar year. As of December 31, 2022, 3,205,132 common shares were available for future award grants under the New Plan (December 31, 2021: 952,632 common shares). ISOs may be granted with respect to a maximum fixed amount equal to 20% of the shares reserved for issuance under the New Plan as of June 7, 2018.
On January 5, 2022, board of directors approved the "Zymeworks Inc. Inducement Stock Option and Equity Compensation Plan" (the "Inducement Plan") and reserved 750,000 of the Company’s common shares for issuance pursuant to equity awards granted thereunder. As of December 31, 2022 ,50,000 common shares were available for future award grants under this plan.
RSUs
During the year ended December 31, 2020, the Company started granting RSUs to certain employees, which typically vest over a period of three years, in the amount of one-third each year on the anniversary of the grant date. RSUs are equity-settled on each vesting date, subject to the grantee’s continued employment with the Company on the vesting date. The fair value of RSUs granted was calculated by using the Company’s closing stock price on the grant date.

As of December 31, 2022, there was $1,738 of unamortized RSU expense that will be recognized over a weighted average period of 2.00 years.
Stock Options
All options granted under the New Plan will have an exercise price determined and approved by the board of directors on the date of the grant, which shall not be less than the market price of the common shares at such time. For the purposes of the New Plan, the market price of a common share shall be the closing sale price of a share on the grant date reported by the stock exchange with the greatest trading volume or, if such day is not a trading day, the closing sale price reported for the immediately preceding trading day. The Company may convert a market price denominated in Canadian dollars into United States dollars and vice versa and such converted amount shall be the market price.
An option shall be exercisable during a period established by the board of directors which shall commence on the date of the grant and shall terminate not later than ten years after the date of the granting of the option. The New Plan provides that the exercise period shall automatically be extended if the date on which it is scheduled to terminate shall fall during a black-out period. In such cases, the extended exercise period shall terminate on the tenth business day after the last day of the black-out period, provided that the exercise period shall in no case be extended beyond the tenth anniversary of the date the option was granted. All options shall vest in accordance with the terms of their grant agreements.

For the year ended December 31, 2022, stock-based compensation expense of $9,516 was recorded in additional paid-in capital and recovery of $3,261 was recorded in the liability classified stock options and ESPP liability accounts (2021: $38,275 in additional paid-in capital and recovery of $27,517 in liability classified stock options and ESPP liability accounts, 2020: $26,945 in additional paid-in capital and $2,171 in liability classified stock options and ESPP liability accounts).
The estimated fair value of stock options granted under the New Plan was determined using the Black-Scholes option pricing model with the following weighted-average assumptions:
Year ended December 31,
2022 2021 2020
Dividend yield 0 % 0 % 0 %
Expected volatility 77.2 % 80.3 % 76.8 %
Risk-free interest rate 2.12 % 1.02 % 0.66 %
Expected average life of options 5.93 years 6.05 years 6.04 years
Expected Volatility - Volatility is a measure of the amount by which a financial variable such as a share price has fluctuated (historical volatility) or is expected to fluctuate (expected volatility) during a period. The Company has calculated the expected volatility using the volatility of its own stock and that of several public entities of similar complexity and stage of development and calculates historical volatility using the volatility of these companies.
Risk-Free Interest Rate - This rate is from the Government of Canada and U.S. Federal Reserve marketable bonds for the month prior to each option grant during the year, having a term that most closely resembles the expected life of the option.
Expected Term - This is the period of time that the options granted are expected to remain unexercised. Options granted have a maximum term of ten years. The Company uses the simplified method to calculate the average expected term, which represents the average of the vesting period and the contractual term.
Share Fair Value - Options granted after the Company’s IPO are issued with exercise price equal to the fair market value of the Company’s common stock on the grant date. Before the IPO, the Company granted stock options at exercise prices not less than the fair value of its common shares as determined by the board of directors, with input from management. Management estimated the fair value of its common shares based on a number of objective and subjective factors, including the most recently available valuation of common shares prepared by independent valuation specialists, external market considerations affecting the biotechnology industry and the historic prices at which the Company sold common shares.
The weighted-average Black-Scholes option pricing assumptions for liability classified stock options outstanding at December 31, 2022 and 2021 are as follows:
December 31,
2022 December 31,
Dividend yield 0 % 0 %
Expected volatility 78.6 % 74.3 %
Risk-free interest rate 4.00 % 0.99 %
Expected average option term 1.90 years 2.35 years
Number of liability classified stock options outstanding 721,985 911,400
The total intrinsic value of stock options exercised during the years ended December 31, 2022, 2021 and 2020 was $53, $10,998 and $19,446 respectively. At December 31, 2022, the unamortized compensation expense related to unvested options was $13,879. The remaining unamortized compensation expense as of December 31, 2022 will be recognized over a weighted-average period of 1.5 years.
f.Employee Stock Purchase Plan
On April 10, 2017, the Company’s shareholders approved an employee stock purchase plan (“ESPP”) which became effective immediately prior to the consummation of the Company’s IPO. On June 7, 2018, certain amendments to the ESPP were approved by shareholders. Prior to these amendments, the ESPP allowed eligible employees to acquire common shares at a discounted purchase price of 85% of the market value of the Company’s common shares on the purchase date. The ESPP, as amended, allows eligible employees to acquire common shares at a discounted purchase price of the lesser of (i) 85% of the market price of a common share on the first day of the applicable purchase period and (ii) 85% of the market price of a common share on the purchase date. The ESPP qualifies as an “employee stock purchase plan” within the meaning of Section 423 of the Code for employees who are United States taxpayers.
The Company currently holds offerings consisting of a single six-month purchase period commencing on January 1 and July 1 of each calendar year, with a single purchase date at the end of the purchase period on June 30 and December 31 of each calendar year.
Eligible employees are able to contribute up to 15% of their gross base earnings for purchases under the ESPP through regular payroll deductions. Purchases of shares under the ESPP are limited for each employee at twenty-five thousand dollars worth of the Company’s common shares (determined using the lesser of (i) the market price of a common share on the first day of the applicable purchase period and (ii) the market price of a common share on the purchase date) for each year such purchase right is outstanding.
As this plan is considered compensatory, the Company recognizes compensation expense on these awards based on their estimated grant date fair value using the Black-Scholes option pricing model. The Company recognizes compensation expense in the consolidated statements of income (loss) and comprehensive income (loss) on a straight-line basis over the requisite service period. For the year ended December 31, 2022, the Company recorded compensation expense of $424 (2021: $1,016, 2020: 803) in research and development expense and general and administrative expense accounts. As of December 31, 2022, the total amount contributed by ESPP participants and not yet settled is $287 (December 31, 2021: $1,243).
11. Government Grants and Credits
Year Ended December 31,
2022 2021 2020
CEWS and CERS subsidies $ 130 $ 3,402 $ 3,031
SR&ED credits, net - 78 142
Total $ 130 $ 3,480 $ 3,173
In April 2020, the Government of Canada announced the CEWS and CERS programs for Canadian employers whose businesses were affected by the COVID-19 pandemic. The CEWS and CERS provide a subsidy of up to a certain percentage of eligible employees’ eligible remuneration and eligible rent payments, subject to certain criteria. The Company applied for the CEWS and CERS to the extent it met the requirements to receive the subsidy and recognized $130 (2021: $2,805) and nil (2021: $597) in total CEWS and CERS subsidies respectively, as a reduction to salaries and benefits expense and rent expense in research and development expense and general administrative expense in the consolidated statement of income (loss) and comprehensive income (loss).
For the year ended December 31, 2022, the Company recognized refundable investment tax credits of nil as a reduction of research and development expense. Although the Company has used its best judgment and understanding of the related income tax legislation in determining its claims, it is possible the amounts could increase or decrease materially in the future, as the Canada Revenue Agency and Revenue Québec reserve the right to review and audit the investment tax credit claims.

In December 2021, BeiGene dosed the first patient in South Korea in the pivotal HERIZON-GEA-01 study and the Company recognized revenue of $8.0 million in relation to this milestone.
In relation to the Zanidatamab Zovodotin Agreement, the Company identified the following promised goods and services at the inception of the BeiGene agreement that are material: development and commercial licenses, initial transfer of the Company’s technologies and relevant know-how, continuing technology transfer, participation in the JSC and other sub-committees, manufacturing technology transfer, provision of development supply, provision of commercial supply, and transfer of future rights related to the development and commercial license. The Company concluded that the licenses and initial technology transfer together are distinct together and the continuing technology transfer and the Company’s participation to the JSC and other sub-committees’ activities are also distinct together. Manufacturing technology transfer, provision of development supply and provision of commercial supply were individually determined to be distinct.
Development and commercial licenses as well as initial transfer of technologies and relevant know-how were considered to be a single performance obligation while continuing technology transfer and participation in the JSC and other sub-committees together were considered as a single performance obligation. Remaining deliverables were considered individually distinct. No performance obligations were completed by the Company as of December 31, 2022 as the initial transfer of technologies and relevant know-how is not going to start until the earlier of completion of the Company’s Phase-1 clinical studies for zanidatamab zovodotin or completion of dose escalation studies. Accordingly, no revenue was recognized from the Zanidatamab Zovodotin Agreement to date.
As of December 31, 2022, the Company recorded $32,941 of the upfront fees from the zanidatamab and zanidatamab zovodotin agreements as deferred revenue on the Company’s consolidated balance sheet (December 31, 2021: $32,941).

Included in the balance of unrecognized tax benefits at December 31, 2022, 2021 and 2020 are potential benefits of nil that, if recognized, would affect the effective tax rate on income from continuing operations. Recognition of these potential benefits would result in a deferred tax asset in the form of net operating loss carry-forward, which would be subject to a valuation allowance based on conditions existing at the reporting date.
The Company recognizes interest expense and penalties related to unrecognized tax benefits within the provision for income tax expense on the consolidated statements of income (loss) and comprehensive income (loss).
The Company currently files income tax returns in Canada, the United States, the United Kingdom, and Ireland, the jurisdictions in which the Company believes that it is subject to tax. Further, while the statute of limitations in each jurisdiction where an income tax return has been filed generally limits the examination period, as a result of loss carry-forwards, the limitation period for examination generally does not expire until several years after the loss carry-forwards are utilized. Other than routine audits by tax authorities for tax credits and tax refunds that the Company has claimed, management is not aware of
any other material income tax examination currently in progress by any taxing jurisdiction. Tax years ranging from 2006 to 2022 remain subject to Canadian income tax examinations. Tax years ranging from 2019 to 2022 remain subject to U.S. income tax examinations. Tax year 2022 remain subject to U.K and Ireland income tax examinations.
15. Leases
The Company leased separate office and laboratory spaces in Vancouver, British Columbia, which expired in February 2022. On January 25, 2019, the Company entered into a lease for a new building in Vancouver, including both office and laboratory space. This lease commenced for accounting purposes in May 2021 and construction of leasehold improvements was completed during the year ended December 31, 2022. This lease has an initial term of ten years, with two five-year extension options. In addition, the Company leases office space in Seattle, Washington with lease terms expiring in May 2027. None of the optional extension periods have been included in the determination of the right-of-use assets or the lease liabilities for operating leases as the Company did not consider it reasonably certain that the Company would exercise any such options. The Company also leases office equipment under capital lease agreements.
The balance sheet classification of the Company’s lease liabilities was as follows:
December 31,
2022 December 31,
Operating lease liabilities:
Current portion $ 3,322 $ 1,310
Long-term portion 24,667 30,923

Total lease liabilities $ 28,129 $ 32,355
Cash paid for amounts included in the measurement of operating lease liabilities for fixed lease payments for the year ended December 31, 2022 was $4,471 and was included in net cash used in operating activities in the consolidated statement of cash flows.
As of December 31, 2022, the maturities of the Company’s operating lease liabilities were as follows:

Operating lease liabilities $ 27,989
As of December 31, 2022, the weighted average remaining lease term is 7.8 years and the discount rate used to determine the operating lease liability was 4.8% for leases in Canadian dollars and 2.8% for leases in U.S. dollars.
During the year ended December 31, 2022, the Company incurred total operating lease expenses of $7,795 (2021 - $5,658, 2020 - $3,595), which included lease expenses associated with fixed lease payments of $6,609 (2021 - $5,323 and 2020 -
$3,156), and variable payments associated with common area maintenance and similar expenses of $1,186 (2021 - $335 and 2020 - $439).
During the year ended December 31, 2022, the Company did not recognize any impairment losses on its right-of-use assets (2021: nil).
16. Financial Instruments
The Company evaluates financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level of classification each reporting period. This determination requires the Company to make subjective judgments as to the significance of inputs used in determining fair value and where such inputs lie within the fair value hierarchy.
Fair Value Measurements
The Company measures certain financial instruments and other items at fair value.
To determine fair value, the Company uses a fair value hierarchy that prioritizes the inputs, assumptions and valuation techniques used to measure fair value. The three levels of the fair value hierarchy are as follows:
• Level 1 inputs are unadjusted quoted market prices for identical instruments available in active markets.
• Level 2 inputs are inputs other than Level 1 prices, such as prices for a similar asset or liability that are observable either directly or indirectly. If the asset or liability has a contractual term, the input must be observable for substantially the full term. An example includes quoted market prices for similar assets or liabilities in active markets.
• Level 3 inputs are unobservable inputs for the asset or liability and will reflect management’s assessment about market assumptions that would be used to price the asset or liability.
Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. Changes in the observability of valuation inputs may result in a reclassification of levels for certain securities within the fair value hierarchy.
The Company’s financial instruments consist of cash and cash equivalents, short-term and long-term investments in marketable and other securities, accounts receivable, accounts payable and accrued liabilities, contingent consideration, finance and operating lease obligations, and other long-term liabilities.
The carrying values of cash and cash equivalents, short-term investments in marketable securities, accounts receivable and accounts payable and accrued liabilities approximate their fair values due to the near-term maturities of these financial instruments. As at December 31, 2022, long-term investments in equity securities of private entities are accounted for as available for sale at their fair values. Other long-term liabilities for contingent consideration related to business acquisitions are recorded at fair value on the acquisition date and are adjusted quarterly for changes in fair value. Changes in the fair value of contingent consideration liabilities can result from changes in anticipated milestone payments and changes in assumed discount periods and rates. These inputs are unobservable in the market and therefore categorized as level 3 inputs as defined above.
The following tables present information about the Company’s assets and liabilities that are measured at fair value on a recurring basis, and indicate the fair value hierarchy of the valuation techniques used to determine such fair value:

Year ended December 31, 2021 $ 1,285 $ 213 $ - $ 1,498
Concentration of Credit Risk
Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of cash and cash equivalents, short-term investments, long-term investments and accounts receivable. Cash and cash equivalents and investments in marketable securities are invested in accordance with the Company’s cash investment policy with the primary objective being the preservation of capital and maintenance of liquidity. The cash investment policy includes guidelines on the quality of financial instruments and defines allowable investments that the Company believes minimizes the exposure to concentration of credit risk. The Company limits its exposure to credit loss by placing its cash and cash equivalents, short-term investments and long-term investments with high credit quality financial institutions.
At December 31, 2022, the maximum exposure to credit risk for accounts receivable was $33,400 (December 31, 2021: $15,614) and all accounts receivable are due within the next 12 months. As at December 31, 2022 and December 31, 2021, the Company has recognized nominal amounts of provision for expected credit losses in relation to accounts receivable.
Liquidity Risk
Liquidity risk is the risk that the Company will encounter difficulty in meeting the obligations associated with its financial liabilities that are settled by delivering cash or another financial asset. The Company’s short-term cash requirements are primarily to settle its financial liabilities, which consist primarily of accounts payable and accrued liabilities falling due within 45 days and current portion of lease obligations falling due within the next 12 months, with medium term requirements to invest in property and equipment and research and development. The Company’s principal sources of liquidity to settle its financial liabilities are cash, cash equivalents and short-term investments, collection of accounts receivable relating to research collaboration and license agreements and additional public equity offerings as required. The Company believes that these principal sources of liquidity are sufficient to fund its operations for at least the next 12 months, and potentially beyond.
Foreign Currency Risk
The Company incurs certain operating expenses in currencies other than the U.S. dollar and accordingly is subject to foreign exchange risk due to fluctuations in exchange rates. The Company does not use derivative instruments to hedge exposure to foreign exchange risk due to the low volume of transactions denominated in foreign currencies. At December 31, 2022, the Company’s net monetary liabilities denominated in Canadian dollars were $1,593 (C$2,144).
The operating results and financial position of the Company are reported in U.S. dollars in the Company’s consolidated financial statements. The fluctuation of the U.S. dollar relative to the Canadian dollar and other foreign currencies will have an
impact on the reported balances for net assets, net income (loss) and stockholders’ equity in the Company’s consolidated financial statements.
17. Commitments and Contingencies
Commitments
The Company has entered into research collaboration agreements with strategic partners in the ordinary course of operations that may include contractual milestone payments related to the achievement of pre-specified research, development, regulatory and commercialization events and indemnification provisions, which are common in such agreements. Pursuant to the agreements, the Company is obligated to make research and development and regulatory milestone payments upon the occurrence of certain events and royalty payments based on net sales. The maximum amount of potential future indemnification is unlimited, however, the Company currently holds commercial and product liability insurance that limits the Company’s liability and may enable it to recover a portion of any future amounts paid. Historically, the Company has not made any indemnification payments under such agreements and believes that the fair value of these indemnification obligations is minimal. Accordingly, the Company has not recognized any liabilities relating to indemnification obligations for any period presented in the consolidated financial statements.
In connection with the Company’s 2016 Kairos acquisition, the Company may be required to make future payments of up to an
aggregate of C$8.5 million, consisting of (i) a C$2.5 million payment when the first patient is dosed in the first Phase 2 trial and (ii) a C$6.0 million payment when the first patient is dosed in the first Phase 3 trial, to CDRD Ventures Inc. (“CVI”) upon the direct achievement of certain development milestones for products incorporating certain Kairos intellectual property. In addition, CVI is eligible to receive low single-digit royalty payments from the Company on the net sales of such products. For out-licensed products and technologies incorporating certain Kairos intellectual property, the Company may also be required to pay CVI a mid-single digit percentage of certain future revenue. As of December 31, 2022, the contingent consideration had an estimated fair value of $1,248, which has been recorded within other long-term liabilities on the Company’s consolidated balance sheet (December 31, 2021: $1,498). The contingent consideration was calculated using a probability weighted assessment of the likelihood of the milestones being met, a probability adjusted discount rate that reflects the stage of the development and time to complete the development. Contingent consideration is a financial liability and measured at its fair value at each reporting period, with any changes in fair value from the previous reporting period recorded within research and development expenses in the statement of income (loss) and comprehensive income (loss).
Contingencies
From time to time, the Company may be subject to various legal proceedings and claims related to matters arising in the ordinary course of business. The Company does not believe it is currently subject to any material matters where there is at least a reasonable possibility that a material loss may be incurred.
18. Restructuring
In January 2022, the Company started implementing a restructuring program (the “Restructuring”) as part of its renewed focus on achieving its key strategic priorities and to help create a more cost-efficient organization in order to execute on its strategic priorities. In connection with the Restructuring, the Company made changes to its management team and reduced headcount by approximately 25% by the completion of the Restructuring during the three months period ended March 31, 2022. During the year ended December 31, 2022, the Company recorded the following costs for the Restructuring:
•employee severance and termination benefits of $5,214;
•an offsetting non-cash reversal of previously recognized stock-based compensation expenses for unvested stock and RSU awards of $10,381; and
•other restructuring charges primarily related to accelerated depreciation and accelerated recognition of rent expense in relation to the shutdown of certain facilities of $2,435 and early termination of certain service contracts of $1,275.
Of the net charges, $5,659 expense and $5,516 recovery of stock-based compensation were recorded in research and development expenses, and $3,265 expense and $4,865 stock-based compensation recovery were recorded in general and administrative expenses in the accompanying statements of income (loss) and comprehensive income (loss).
As of December 31, 2022, the net outstanding liability related to employee severance termination benefits and other contract liabilities was approximately $678. The Company recognized the majority of these charges during the year ended December 31, 2022 and does not expect to incur any material additional costs related to the Restructuring.

Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports that the Company files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Any such information is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure.
Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on our evaluation of our disclosure controls and procedures as of December 31, 2022, our Chief Executive Officer and our Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were, in design and operation, effective at the reasonable assurance level.
Management’s Annual Report on Internal Control over Financial Reporting
Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over our financial reporting, as defined in Rule 13a-15(f) and Rule 15d-15(f) of the Exchange Act.
The effectiveness of any system of internal control over financial reporting, including ours, is subject to inherent limitations, including the exercise of judgment in designing, implementing, operating, and evaluating the controls and procedures, and the inability to eliminate misconduct completely. Accordingly, any system of internal control over financial reporting, including ours, no matter how well designed and operated, can only provide reasonable, not absolute, assurances. 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. Management has assessed the effectiveness of our internal control over financial reporting as at December 31, 2022. In making its assessment, management used the criteria set forth in the internal control - integrated framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 COSO framework) to evaluate the effectiveness of our internal control over financial reporting. Based on this evaluation, management has concluded that our internal control over financial reporting was effective as of December 31, 2022.
Attestation Report of Independent Registered Public Accounting Firm
This Annual Report on Form 10-K does not include an attestation report of our independent registered public accounting firm regarding our internal control over financial reporting. For so long as we are not classified as an “accelerated filer” or “large accelerated filer” pursuant to SEC rules, we will continue to be exempt from the auditor attestation requirements of Section 404(b) of Sarbanes-Oxley.
Changes in Internal Control Over Financial Reporting
There were no changes in our internal control over financial reporting during the quarter ended December 31, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
