We discuss many of these risks in greater detail under “Risk Factors.” Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. Given these uncertainties, you should not place undue reliance on these forward-looking statements. 2 We qualify all of the forward-looking statements in this Annual Report by these cautionary statements. Except as required by law, we undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise. SUMMARY OF RISK FACTORS Investing in our common stock is subject to numerous risks and uncertainties, including those described in Part I, Item 1A, “Risk Factors” of this Annual Report. The principal risks and uncertainties affecting our business include the following: • • • • • • • • • • • • • • We have a limited operating history, have incurred significant operating losses since our inception and expect to incur significant losses for the foreseeable future. We may never generate any revenue or become profitable or, if we achieve profitability, we may not be able to sustain it. We will require substantial additional financing to achieve our goals, and a failure to obtain this necessary capital when needed and on acceptable terms, or at all, could force us to delay, limit, reduce or terminate our product development programs, commercialization efforts or other operations. The COVID-19 pandemic may adversely impact our business. We depend heavily on the success of our product candidates, which are in clinical or preclinical development. If we are unable to advance our product candidates in clinical development, obtain regulatory approval and ultimately commercialize our product candidates, or experience significant delays in doing so, our business will be materially harmed. Clinical drug development involves a lengthy and expensive process with an uncertain outcome, and the results of preclinical studies and early clinical trials are not necessarily predictive of future results. Our product candidates may not have favorable results in clinical trials or receive regulatory approval on a timely basis, if at all. We may find it difficult to enroll patients in our clinical trials. If we encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed or otherwise adversely affected. We rely on third parties for the manufacture of our product candidates for clinical and preclinical development and expect to continue to do so for the foreseeable future. We may not be able to maintain orphan drug designations for some of our product candidates, and may be unable to leverage the benefits associated with orphan drug designation, including the potential for market exclusivity. Fast Track designation by the FDA for ONCT-216 or our other product candidates may not actually lead to a faster development or regulatory review or approval process. Interim, topline and preliminary 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. We rely on third parties to conduct many of our preclinical studies and clinical trials. Any failure by a third-party to conduct the clinical trials according to Good Laboratory Practices, Good Clinical Practices, and other requirements and in a timely manner may delay or prevent our ability to seek or obtain regulatory approval for or commercialize our product candidates. If the market opportunities for our products are smaller than we believe they are, our revenue may be adversely affected, and our business may suffer. Our operating results may fluctuate significantly, which makes our future operating results difficult to predict and could cause our operating results to fall below expectations or any guidance we may provide. Our success depends on our ability to protect our intellectual property and our proprietary technologies. 3 Our trademarks, trade names, and service marks referenced in this Annual Report include Oncternal®, which is protected under intellectual property laws and is our property.

Item 1. Business. Overview Oncternal Therapeutics, Inc., or Oncternal, is a clinical-stage biopharmaceutical company focused on the development of novel oncology therapies for the treatment of patients with cancers that have critical unmet medical need. Oncternal focuses drug development on promising, yet untapped biological pathways implicated in cancer generation or progression. The following figure summarizes our current development programs: Zilovertamab Zilovertamab (formerly cirmtuzumab or UC-961) is an investigational, humanized, potentially first-in-class monoclonal antibody designed to: (i) inhibit Receptor tyrosine kinase-like Orphan Receptor 1, or ROR1, a growth factor receptor that is widely expressed on many tumors and that activates pathways leading to increased tumor proliferation, invasiveness and drug resistance; and (ii) bind to a specific functionally important epitope of ROR1. ROR1 is a potentially attractive target for cancer therapy because it is an onco-embryonic antigen, a protein typically expressed during embryogenesis that may confer a survival and fitness advantage when reactivated and expressed by tumor cells. ROR1 overexpression in multiple tumor types, including mantle cell lymphoma, or MCL, chronic lymphocytic leukemia, or CLL, prostate cancer and breast cancer, and its expression has been associated with more aggressive disease, resistance to therapy and shorter progression-free survival, or PFS, and overall survival, or OS. In preclinical models, inhibition of ROR1 has shown anti-tumor activity, and we believe this may have additive or synergistic effects when combined with either targeted therapy or chemotherapy. Preclinical studies demonstrated that zilovertamab bound with high affinity and specificity to ROR1, sparing healthy, non-cancerous tissues. When zilovertamab bound to ROR1, it blocked growth factor Wnt5a signaling, inhibited tumor cell proliferation, migration and survival, and induced differentiation of CLL tumor cells. Zilovertamab was developed in the laboratory of one of our scientific advisors, Professor Thomas Kipps, M.D., Ph.D., Professor of Medicine and Evelyn and Edwin Tasch Chair in Cancer Research at the University 4 of California San Diego, or UC San Diego, with support from the California Institute for Regenerative Medicine, or CIRM. We have an exclusive, worldwide license to develop zilovertamab for certain therapeutic uses from UC San Diego. The U.S. Food and Drug Administration, or FDA, granted orphan drug designations for zilovertamab for the treatment of patients with MCL and for the treatment of patients with CLL/small lymphocytic lymphoma, or SLL, in 2020. Zilovertamab is currently being evaluated in an ongoing Phase 1/2 clinical trial in combination with ibrutinib (Imbruvica) known as CIRM-0001 or the CIRLL (Cirmtuzumab and Ibrutinib targeting ROR1 for Leukemia and Lymphoma) study for the treatment of patients with B-cell lymphoid malignancies, including MCL and CLL. In December 2021, we presented interim clinical data from this study at the American Society of Hematology (ASH) 2021 Virtual Annual Meeting. The objective response rate, or ORR, of 81%, complete response, or CR, rate of 35%, and median progression-free survival, or PFS, of 35.9 months we reported for patients with relapsed/refractory MCL treated with zilovertamab plus ibrutinib compared favorably to the historical ORR of 66%, CR rate of 20% and median PFS of 12.8 months previously published for patients with MCL treated with ibrutinib alone. The combination of zilovertamab and ibrutinib was well tolerated, with a safety profile consistent with or improved compared with historical data for ibrutinib monotherapy. As of January 31, 2022, we have completed enrollment of patients with MCL and CLL in the Phase 1/2 CIRLL study, and those patients are completing therapy or are in long-term follow-up. In January 2022, we announced that following a successful End-of-Phase 2 meeting with the FDA for zilovertamab, we and the FDA agreed on key elements of our potentially pivotal Phase 3 clinical trial of zilovertamab for the treatment of patients with relapsed or refractory MCL. The FDA has also reviewed and agreed upon the key design features and operational details of our Phase 3 clinical trial protocol and statistical analysis plan. We expect to initiate a global Phase 3 study in the second quarter of 2022. In addition, we are supporting two investigator-sponsored studies being conducted at UC San Diego: (i) a Phase 1b clinical trial for metastatic castration-resistant prostate cancer, or mCRPC, study, which has an Investigational New Drug Application, or IND, in effect, and (ii) a Phase 2 clinical trial of zilovertamab in combination with venetoclax, a Bcl-2 inhibitor, in patients with relapsed/refractory CLL, which is open for enrollment. Additional preclinical activities to evaluate zilovertamab in other cancer types, including hematologic malignancies, are ongoing. ROR1 Cell Therapy Program ONCT-808, our lead cell therapy product candidate, is an autologous chimeric antigen receptor, or CAR, T cell, or CAR-T, therapy that targets ROR1, which is in preclinical development as a potential treatment for hematologic malignancies and solid tumors. ONCT-808 utilizes the binding domain of zilovertamab as a single-chain variable region fragment, or scFv. Because zilovertamab has been shown to bind specifically to multiple tumor tissues but not to normal adult tissues in preclinical studies, we believe that zilovertamab-based CAR-T cells may be selective in distinguishing cancer from normal tissues. ONCT-808 was initially developed in collaboration with UC San Diego and is being further evaluated in preclinical studies in collaboration with the Karolinska Institutet in Stockholm, Sweden and the MD Anderson Cancer Center in Houston, Texas. We are working with Lentigen Technology, Inc. (lentivirus manufacturing), or Lentigen, and Miltenyi Biotec B.V. & Co. KG (cell processing) on the manufacturing aspects of the program. We have developed manufacturing production processes for both the lentivirus containing the CAR gene, and the ROR1 CAR-T cell drug product, along with all suitable release test methods enabling the submission to the FDA of an IND for the treatment of patients with relapsed/refractory B-cell malignancies, which we expect to occur in mid-2022. Additionally, our ROR1 cell therapy strategy includes the potential development of a next-generation cell therapy, which could include CAR- expressing immune cells bearing additional features to overcome barriers in the tumor microenvironment. targeting ROR1-expressing cancer cells in solid tumors Also, we are evaluating “off-the-shelf” or allogeneic CAR-expressing immune cells, such as chimeric antigen receptor natural killer, or CAR-NK, cell therapies. We expect partnerships and collaborations to be essential for implementing our next-generation ROR1 cell therapy strategy. 5 ONCT-534 Dual-Action Androgen Receptor Inhibitor, or DAARI, Program ONCT-534 (formerly GTX-534), our lead dual-action androgen receptor inhibitor, or DAARI, product candidate, is in preclinical development as a potential treatment for advanced castration-resistant prostate cancer, or CRPC, and other androgen receptor, or AR, driven diseases. DAARIs interact with both the N-terminal domain, or NTD, and the ligand-binding domain, or LBD, of the AR inducing AR degradation, and have demonstrated preclinical activity in prostate cancer tumor models resistant to approved AR-targeting therapies. We believe ONCT-534 has the potential to address significant unmet needs related to important tumor resistance mechanisms, including AR amplification, splice variants and LBD mutations. ONCT-216 ONCT-216 (formerly TK-216) is a targeted inhibitor of E26 Transformation-Specific, or ETS oncoproteins, including certain overexpressed fusion proteins. Tumorigenic fusion proteins involving the Ewing sarcoma, or EWS, protein and an ETS protein can be found in virtually all cases of Ewing sarcoma. ETS-related translocations or overexpression are also found in many other tumors, such as diffuse large B-cell lymphoma, or DLBCL, prostate cancer and acute myeloid leukemia, or AML. Researchers in the laboratory of Jeffrey Toretsky, M.D., at Georgetown Lombardi Comprehensive Cancer Center, identified the precursor to ONCT-216 using a novel chemical screening assay they developed based on a deep understanding of the underlying biological mechanism of ETS factors. Following this early work, we generated ONCT-216, which is designed to be a specific inhibitor of ETS factors, through the rational design and screening of novel small molecule inhibitors of a critical protein-protein interaction. In preclinical models, ONCT-216 inhibited the interaction between ETS family members and RNA helicase A, or RHA, and by doing so, repressed excessive cell proliferation. We own intellectual property related to ONCT-216 and have an exclusive license to product candidates targeting ETS oncoproteins for therapeutic, diagnostic or research tool purposes from Georgetown University. The FDA has granted rare pediatric disease designation, as well as orphan drug and fast track designations for ONCT-216 for the treatment of Ewing sarcoma. ONCT-216 is currently being investigated as a single agent and in combination with vincristine in an open-label, multicenter Phase 1/2 clinical trial in patients with relapsed or refractory Ewing sarcoma. In the third quarter of 2021, we added a new Phase 2 expansion cohort targeting up to 21 Ewing sarcoma patients to evaluate clinical responses to single agent ONCT-216 at 175 mg/m2/day, treating patients for 28 days per cycle with the next cycle starting immediately after the prior one, to intensify the amount of ONCT-216 administered over time. The expansion cohort is actively enrolling patients. Our team We have assembled a management team, board of directors and scientific founders who have significant experience in successfully developing and commercializing therapeutics in oncology and orphan diseases, having worked or served on the Board of companies such as Amgen, Inc., Bavarian Nordic, Inc. (lead cancer asset acquired by Bristol Meyers Squibb Company), Baxalta Incorporated (acquired by Shire PLC), Cadence Pharmaceuticals, Inc. (acquired by Mallinckrodt plc), Dynavax Technologies Corporation, Elan Corporation (acquired by Perrigo), Eli Lilly and Company, Gilead Sciences, Inc., Innocrin Precision Therapeutics, Inc., Johnson & Johnson, Merck, Micromet, Inc. (acquired by Amgen, Inc.), Pfizer, Inc., Roche Holding AG, Sorrento Therapeutics, Inc., Tracon Pharmaceuticals, Inc., and Zavante Therapeutics, Inc. (acquired by Nabriva Therapeutics plc). Our strategy Our mission is to build a leading oncology company that creates novel and transformative treatments for a wide range of oncology indications for which there are significant unmet medical needs. We believe our investigational agents target novel cancer pathways and have unique mechanisms of action. Our current pipeline is derived from our ability to identify therapeutic candidates that have generated promising, late-stage preclinical results or clinical data, and in-license them for further development. We are particularly focused on therapeutic approaches for which there is a genetic or protein biomarker that can be used to identify populations of patients most likely to respond. We prioritize targets that we believe have the potential to 6 transform the treatment paradigm of difficult-to-treat cancers with either single agent or combination therapy. As is the case for many oncology products, we believe that potential efficacy in one indication suggests the potential for application in other indications that carry the same target. Our focus is on hematological malignancies and prostate cancer as we believe our product pipeline can have the greatest impact in addressing unmet needs of patients diagnosed with these diseases. Key elements of our strategy are as follows: • • • • • advance zilovertamab through clinical development in multiple indications, with a primary focus on MCL as we expect to initiate a potentially pivotal Phase 3 clinical trial of zilovertamab for the treatment of patients with relapsed or refractory MCL in the second quarter of 2022; advance ONCT-808, our ROR1-targeting autologous CAR-T cell therapy candidate, into clinical development for the treatment of patients with hematological malignancies, as we expect to submit a U.S. IND application in mid-2022; advance ONCT-534, our lead DAARI product candidate, into IND-enabling studies and subsequently into clinical development for the treatment of patients with advanced prostate cancer; advance ONCT-216 through clinical development for the treatment of patients with relapsed/refractory Ewing sarcoma, including completion of the ongoing Phase 1/2 clinical trial; and evaluate our product pipeline in preclinical studies in additional tumors with a focus on hematological malignancies and prostate cancer. Business Update Regarding COVID-19 The COVID-19 worldwide pandemic has presented substantial public health and economic challenges and continues to affect economies, financial markets and business operations around the world. The pandemic may continue to directly or indirectly affect the timeline for our manufacturing activities, planned IND submissions and clinical trials, including our global Phase 3 study of zilovertamab that we plan to initiate in the second quarter of 2022. The full extent to which the COVID-19 pandemic will continue to directly or indirectly impact our results of operations and financial condition, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain or treat it, the success or failure of ongoing vaccination programs worldwide, the emergence and spread of additional variants of COVID-19, as well as the economic impact on local, regional, national and international markets. Our Product Candidates Zilovertamab - monoclonal antibody targeting ROR1 Zilovertamab scientific background: inhibition of ROR1 as a therapeutic strategy in cancer ROR1 is an onco-embryonic protein essential for normal fetal development whose expression is suppressed at birth unless reactivated as a survival factor by many different cancers. The switching-on of ROR1 is consistent with the general process of de-differentiation in cancer, in which normal cells lose their highly differentiated functions and return to a more primitive state, where they exhibit a greatly increased capacity for invasion, metastasis and resistance to treatment. This de-differentiation is associated with expression of a number of genes normally restricted to fetal development, one of which is ROR1. Cancer cells with the highest potential for self-renewal are sometimes referred to as tumor-initiating cells or cancer stem cells and are capable of invading other tissues or metastasizing to form tumors in distant sites in the body. These tumor-initiating cells are also the cells that have been found to be the most resistant to standard cancer therapies including chemotherapy and radiation therapy. Cancer cells that overexpress ROR1 have been shown to have increased survival, migration and resistance to chemotherapy. 7 Over-expression of ROR1 has been reported in multiple hematological and solid tumor types. Histological staining of over 350 human tumor samples identified that a majority expressed ROR1, including 90% or more of uterine cancers, lymphomas and prostate cancers. Cancer type Uterus MCL CLL Lymphoma Prostate Skin Pancreas ROR1 Expressed (%) 96% >95% 95% 90% 90% 89% 83% Cancer type Adrenal Lung Breast Testicular Colon Ovarian Bladder ROR1 Expressed (%) 83% 77% 75% 73% 57% 54% 43% High ROR1 expression on patients’ tumor cells in a variety of cancers is associated with the development of metastases, and early relapse after therapy. ROR1 expression levels on patients’ tumor cells is higher in cancers that are more advanced or poorly differentiated. For example, whereas Grade 1 or 2 ovarian tumors were found to be 21% positive for ROR1, Grade 3 or 4 tumors were found to be 62% positive for ROR1. High expression of ROR1 has been associated with more aggressive disease and shorter patient survival in multiple tumor types, including CLL, breast cancer and ovarian cancer. Inhibition of ROR1 signaling or silencing of ROR1 expression in multiple preclinical cancer models including breast cancer, ovarian cancer and glioblastoma, was associated with suppressing the expression of genes characteristic of tumor-initiating cells, and with repression of cancer migration and metastasis. Preclinical models have also demonstrated that inhibition of ROR1, or blocking of Wnt5a-induced signaling, inhibited tumor cell proliferation, migration and survival, and induced differentiation of the tumor cells – resulting in fewer metastases and improved survival. Inhibition of ROR1 has been demonstrated in preclinical models to be additive to, or synergistic with, chemotherapy agents such as paclitaxel, and with targeted therapy agents such as ibrutinib and venetoclax. In addition, inhibition of ROR1 has been shown to enhance sensitivity of cancer cells to targeted therapy with agents, such as erlotinib and may increase apoptosis and decrease proliferation. In summary, we believe that ROR1 is an attractive therapeutic target in oncology for several reasons: • • • • • ROR1 is widely expressed on many tumors, including hematologic malignancies and solid tumors; Expression of high levels of ROR1 on patients’ tumors is associated with more rapid disease progression, resistance to therapy and shorter patient survival, and therefore may represent an especially high unmet medical need; Blocking of ROR1 activity in preclinical models inhibited tumor cell proliferation, migration and survival, and induced differentiation of the tumor cells, thus depriving the cancer of essential functionalities; Inhibition of ROR1 has been observed in preclinical models to be synergistic with certain chemotherapies and targeted therapies, potentially allowing for safer and more efficacious combination therapies; and Clinical data presented for MK-2140 (formerly VLS-101) a ROR1-targeting antibody-drug conjugate, or ADC, presented at the ASH 2021 Annual Meeting did not reveal any unusual or unexpected off-tumor organ toxicity and are consistent with our clinical observations. Zilovertamab is the ROR1 antibody used in the MK-2140 product candidate. 8 Two notable acquisitions in 2020 involved companies developing product candidates targeting ROR1: Merck & Co. acquired VelosBio, Inc. and its ROR1-targeting ADC (which was initially developed at Oncternal), and Boehringer-Ingelheim acquired NBE Therapeutics and its ROR1-targeting ADC. Zilovertamab development in MCL and CLL MCL disease overview MCL is an aggressive form of non-Hodgkin’s lymphoma. There are approximately 4,200 new cases of MCL each year in the U.S., with the average age at diagnosis in the mid-60s. MCL is an aggressive lymphoma and carries a poor prognosis, with a median survival of about two to five years. The 10- year survival rate is only approximately 5-10%. While there are several therapeutic options available to treat patients with relapsed or refractory MCL, we believe none of these options offers curative benefit, with most patients relapsing in less than 20 months. Inhibitors of Bruton’s Tyrosine kinase, or BTK, such as ibrutinib (Imbruvica), are emerging as a standard of care in patients who have failed other therapies. Most patients progress after 1-2 years of BTK inhibitor monotherapy (Rule et al 2017). As a result, we believe that more effective and better tolerated therapies with shorter treatment periods represent a significant unmet need. CLL disease overview CLL is the most common form of leukemia in adults, accounting for 25-30% of all leukemias in the U.S. According to The Surveillance, Epidemiology, and End Results (SEER) Program, an estimated 21,250 new cases of CLL were expected to occur in the U.S. in 2021, and in 2018 the prevalence of CLL in the U.S. was estimated to be 195,129 patients. CLL is primarily a disease of older adults. The median age at diagnosis is 71 years of age. Most patients are diagnosed as a result of routine blood work when elevated levels of lymphocytes are detected. BTK inhibitor therapy has emerged as a standard of care for CLL and is recommended by the National Comprehensive Cancer Network (NCCN) guidelines as first-line therapy. Patients with CLL can experience a substantial period of disease control, but the disease eventually recurs, and is more likely to do so for patients with previous CLL therapy. Adverse events have been shown in a real-world analysis to limit ibrutinib treatment duration for almost half of all patients. An acceptable safety profile may be particularly important for patients with CLL who are older and may have multiple co- morbidities. According to Evaluate Pharma, the global market for CLL therapies was estimated to be $9.1 billion in 2021, largely driven by targeted therapies, including ibrutinib, venetoclax, and acalabrutinib. We believe that CLL represents an attractive clinical and commercial opportunity for zilovertamab. Zilovertamab preclinical summary in MCL and CLL ROR1 is a potentially attractive target for cancer therapy because it is an onco-embryonic antigen, which is a protein typically expressed during embryogenesis that may confer a survival and fitness advantage when reactivated and expressed by tumor cells. ROR1 is over-expressed in many different cancers, including MCL, CLL, breast cancer and prostate cancer, and has been reported to be associated with more aggressive disease, resistance to therapy and shorter PFS or OS. In preclinical models, inhibition of ROR1 has shown anti-tumor activity and we believe may have additive or synergistic effects when combined with either targeted therapy or chemotherapy. Zilovertamab is an investigational, humanized monoclonal antibody designed to bind to a specific functionally important epitope of ROR1. The ligand for ROR1 in hematologic malignancies is Wnt5a, a secreted glycoprotein that has a critical role in embryonic and fetal development. Researchers at the UC San Diego School of Medicine discovered that targeting a critical epitope on ROR1 was key to inhibiting Wnt5a activation, specifically targeting ROR1 expressing tumors. This led to the development of zilovertamab, which binds this critical epitope of ROR1. Preclinical studies demonstrated that zilovertamab binds with high affinity and specificity to ROR1, sparing healthy, non-cancerous tissues. Zilovertamab was not observed to bind to normal adult tissues in a Good Laboratory Practice, or GLP, tissue cross-reactivity study. 9 Preclinical studies have shown that ROR1 expression on tumor cells accelerated the development and progression of leukemia in animal models of CLL, and that Wnt5a enhanced CLL cell viability, migration and proliferation in a ROR1-dependent manner. Patients with high levels of ROR1 on their CLL cells have more aggressive disease and have a significant reduction in survival. An analysis of MCL and CLL patient samples has shown that ROR1 surface expression, as well as secreted Wnt5a levels, were comparable between patients with MCL and CLL. Preclinical studies also showed that when zilovertamab bound to ROR1, it blocked growth factor Wnt5a signaling, inhibited tumor cell proliferation, migration and survival, and induced differentiation of CLL tumor cells. Preclinical studies with zilovertamab showed that treating MCL or CLL patient’s tumor cells with a combination of zilovertamab and ibrutinib led to reduced proliferation. Additional in vitro studies showed that the combination of zilovertamab plus BTK inhibitor remains active in certain MCL cells that had become insensitive to BTK inhibitor alone. In vivo studies conducted in mouse models of human CLL have shown that ibrutinib and zilovertamab exerted antitumor activities through independent pathways; that is, inhibition of BTK by ibrutinib did not alter ROR1 signaling, nor did it impair the rate at which zilovertamab blocked ROR1 signaling. The combination of both drugs reduced the size of the spleen, the primary site of leukemic disease in these mice, as well as the number of CLL cells in these spleens. Further preclinical studies suggested that zilovertamab was synergistic with venetoclax in vitro. Zilovertamab clinical development in MCL and CLL Zilovertamab Phase 1 clinical trial in patients with CLL A Phase 1 dose escalation clinical trial of zilovertamab, which was funded primarily by Oncternal and CIRM, was conducted in 26 patients with actively progressing CLL who had relapsed or refractory disease. Patients received four doses of zilovertamab administered every two weeks in cohorts of three, with patients receiving escalating doses ranging from 0.15 to 20 mg/kg/dose. Zilovertamab infusions were generally well tolerated. There were no dose-limiting toxicities, no serious adverse events, and no discontinuations related to adverse events. The most common adverse events included anemia, thrombocytopenia, and neutropenia, which were primarily attributed to the underlying CLL. Pharmacokinetic data showed a plasma half-life of approximately 32 days following four doses of zilovertamab at 16 mg/kg. In this clinical trial, 22 patients were evaluable for response assessment; four patients who discontinued zilovertamab early without meeting criteria for progressive disease were not considered evaluable. No patients met criteria for complete or partial remission following this brief treatment. Seventeen of 22 evaluable patients had stable disease, or SD. Five patients had progressive disease. Most patients experienced reductions in their leukemic lymphocyte counts and were able to delay initiation of further treatments for an average of 262 days, at which point plasma levels of zilovertamab were undetectable. Although zilovertamab therapy was limited to four doses, one patient who received zilovertamab at 20 mg/kg had a greater than 50% reduction in lymphadenopathy. Analysis of blood samples from these patients prior to treatment showed significantly higher plasma levels of Wnt5a compared to healthy matched controls. Patients also had high levels of expression of ROR1 on their CLL cells. In addition, when compared to baseline, cells from zilovertamab treated patients showed a reduction in expression of a panel of genes identified as being highly correlated with stem cells and oncogenic dedifferentiation. These results were consistent with preclinical observations that zilovertamab-induced ROR1 inhibition may drive cells away from a stem-cell-like profile. Zilovertamab CIRLL Phase 1/2 clinical trial in combination with ibrutinib in patients with MCL and CLL Oncternal and UC San Diego, with funding from CIRM, and a donation of ibrutinib product from Pharmacyclics LLC, are conducting a Phase 1/2 trial of zilovertamab in combination with ibrutinib in patients with relapsed/refractory MCL, or patients with CLL who are either relapsed/refractory or treatment-naïve (the CIRLL study). This clinical trial was designed to evaluate the safety, pharmacokinetics, pharmacodynamics, immunogenicity, and antitumor activity of zilovertamab in combination with ibrutinib in adult patients with adequate performance status and organ function. The study has 3 parts: 10 Part 1 Dose Finding is a Phase 1b, open-label, sequential allocation, dose-finding evaluation of the sequential administration of zilovertamab monotherapy for 4 weeks followed by zilovertamab plus ibrutinib therapy in patients with relapsed/refractory MCL or CLL/SLL. Part 2 Expansion is a Phase 2, open-label evaluation of the concurrent administration of zilovertamab plus ibrutinib in patients with relapsed/refractory MCL or CLL/SLL, using the recommended dose regimen for zilovertamab derived from Part 1. Part 3 is a 2:1 randomized Phase 2 open-label, controlled, 2-arm, parallel group evaluation of the clinical activity and safety of zilovertamab plus ibrutinib versus ibrutinib alone in patients with treatment-naïve or relapsed/refractory CLL/SLL only. We have completed enrollment of patients with CLL in Parts 1, 2 and 3, and those patients are completing therapy or are in long-term follow-up. Following an evaluation of safety and PK data from Part 1, the recommended dose regimen, or RDR, of zilovertamab for Part 2 was determined to be 600 mg of zilovertamab administered intravenously every two weeks for three doses, followed by dosing every four weeks until disease progression or intolerance develop. This zilovertamab regimen was designed and chosen to be used in combination with 560 mg of ibrutinib once daily for patients with MCL, or 420 mg of ibrutinib administered once daily for patients with CLL, which are the FDA-approved doses of ibrutinib in these indications. Zilovertamab CIRLL Phase 1/2 clinical trial interim data in MCL In December 2021, we presented updated interim data from the CIRLL trial in patients with MCL and CLL at the ASH 2021 Annual Meeting. As of the October 1, 2021 data cutoff date, 26 of the 31 patients with relapsed/refractory MCL enrolled in the dose-finding and dose-expansion cohorts of the CIRLL Phase 1/2 clinical trial were evaluable for efficacy. These patients had high-risk factors and were heavily pre-treated at study entry, 52% with a high Ki-67 proliferative index (≥30%), or High Ki-67 Patients, and 45% with intermediate/high simplified MCL international prognostic impact (sMIPI) score. The majority of drug-related treatment-emergent adverse event, or TEAES, and all Grade 3 or higher TEAEs in this study were deemed to be related to ibrutinib by the Investigators. No Grade 3 or higher TEAEs were deemed to be related to zilovertamab alone, and no new events were deemed to be unique to the combination therapy. The adverse event profile for ibrutinib plus zilovertamab was consistent with the published literature and prescribing information for single‑agent ibrutinib. Encouraging TEAEs related to myelosuppression appeared to be lower than expected for ibrutinib treatment, so quantitative analysis of complete blood count data for MCL was undertaken. Grade 3 or greater neutrophil decrease and platelets decrease of 9.7% for zilovertamab plus ibrutinib, respectively, appear to be qualitatively lower than the 29% Grade 3 or greater neutrophils decreased and 17% platelets decreased reported for the ibrutinib MCL registration study. This could be related to the observation that residual tumor cells during ibrutinib treatment express ROR1, which is activated by its ligand Wnt5a, leading to cross-activation of inflammatory pathways including JAK/STAT and secretion of inflammatory chemokines and cytokines including IL6 and IFN-gamma. Zilovertamab has been shown to inhibit this inflammatory activity. 11 The clinical outcomes reported for patients with MCL in Study CIRM-0001 were very encouraging. The ORR was 81% (21 of 26 evaluable patients) and: (i) nine (35%) achieved a CR; (ii) 12 (46%) achieved a partial response, or PR; and (iii) three (12%) had SD, for a total clinical benefit rate (CR, PR, SD) of 92% as of the data cutoff date. CRs have remained durable for up to 32 months. The ORR and median duration of response were favorable in patients with high-risk features associated with difficult to treat disease. High Ki-67 Patients had an ORR of 85% and a median duration of response of 14 months (95% confidence interval 13.7 months - not evaluable). Patients that had received more than one systemic prior therapy had an ORR of 82%, with the median duration of response not reached for patients receiving two prior lines of systemic therapy and 34 months (95% confidence interval 13.7 months to 34.1 months) for patients receiving three or more prior lines of systemic therapy. Five patients had received prior treatment with ibrutinib, with two achieving CRs and two achieving PRs. One patient that received prior treatment with ibrutinib had SD. Median PFS was 35.9 months, after a median follow-up of 14.4 months (95% confidence interval 11.4 months to 19.3 months), regardless of the number of prior systemic therapies. Median PFS had not been reached for patients achieving a CR. We believe these clinical results have the potential to translate into significantly improved clinical outcomes because they compare favorably with published historical data of a merged analysis of 370 patients with relapsed/refractory MCL from three clinical trials who had received a median of two prior therapies (Rule et al., 2017, British Journal of Haematology), which showed an ORR of 66%, CR rate of 20%, and median PFS of 12.8 months (95% confidence interval 8.5 – 16.6 months) for patients with MCL who were treated with single agent ibrutinib. Results from the ASH 2021 Annual Meeting poster presentation for patients with MCL treated with zilovertamab plus ibrutinib are shown in the figures below. Figure 1. Study CIRM-0001.

Zilovertamab CIRLL Phase 1/2 clinical trial interim data in CLL 14 The interim CIRM-0001 study results for patients with CLL reported at ASH 2021 were also encouraging. As of the October 1, 2021 data cutoff date, all 34 patients with CLL enrolled in the dose-finding and dose-confirming cohorts of this clinical trial were evaluable for efficacy. Patients had high-risk factors, and most were heavily pre-treated at study entry, with 71% having RAI staging II or higher and a median of two systemic prior therapies (range 1-15). The ORR was 91% (31 of 34 evaluable patients), consistent with prior published results. The CR rate was 6% (two of 34 evaluable patients). Twenty-nine patients (85%) achieved a PR and three patients (9%) had SD, for a total clinical benefit rate (CR, PR, SD) of 100%. Median PFS in patients with two or fewer prior therapies had not been reached, and patients with more than two prior therapies had a median PFS of 36.1 months after a median follow-up of 29.0 months (95% confidence interval 27.6 months to 31.6 months) in this high risk and mostly heavily pre-treated CLL population. Based on the Kaplan-Meier curve, landmark progression-free survival, or PFS, of approximately 85% and approximately 65% at 24 and 36 months, respectively, for CLL patients who had previously received two or more prior lines of therapy compared favorably to historical ibrutinib monotherapy of approximately 65% and approximately 50%, respectively (Byrd 2019). Landmark PFS was 100% at 36 months for CLL patients with two or fewer prior lines of therapy, which compares favorably to historical ibrutinib monotherapy of approximately 75% (Byrd 2019). Thirty-one patients with CLL have also been enrolled in the (2:1) randomized efficacy cohort of the clinical trial, of which 22 were evaluable for efficacy. Data on this cohort are maturing, and median PFS for both arms had not been reached as of the October 1, 2021 cutoff date. Figure 6. Study CIRM-0001. Best Tumor Response from Baseline (Percentage Reduction); Patients with CLL; Evaluable Population Administered Zilovertamab and Ibrutinib. 15 Figure 7. Study CIRM-0001. PFS in the CLL Cohort in Phase 1/2 Clinical Trial of Zilovertamab in Combination with Ibrutinib, as of October 1, 2021. We expect to announce a data update from this Phase 1/2 clinical trial in the second quarter of 2022. Zilovertamab Phase 3 Study ZILO-301 in patients with Relapsed/Refractory MCL In January 2022, we announced that following a successful End-of-Phase 2 meeting with the FDA for zilovertamab, we and the FDA agreed on key elements of the company’s potentially pivotal Phase 3 clinical trial of zilovertamab for the treatment of patients with relapsed or refractory MCL. The FDA has also reviewed and agreed upon the key design features and operational details of our Phase 3 clinical trial protocol and statistical analysis plan. Based on these agreements, we plan to conduct ZILO-301, a Phase 3 clinical trial entitled “Randomized, Double-blind, Placebo-controlled, Multi-center Phase 3 Study of Zilovertamab Plus Ibrutinib Versus Ibrutinib Plus Placebo in Patients with Relapsed or Refractory Mantle Cell Lymphoma.” The study will randomize patients with relapsed or refractory MCL who have experienced SD or achieved a PR after receiving four months of oral ibrutinib therapy to receive either blinded zilovertamab or placebo, and all patients will continue receiving oral ibrutinib. The primary endpoint, intended to support submission of a Biologics License Application, or BLA, seeking regular FDA approval, will be PFS. An interim analysis potentially supporting submission of a BLA seeking accelerated FDA approval will be conducted with a primary endpoint of ORR, plus Duration of Response, or DOR. The FDA previously provided positive feedback on the sufficiency of the preclinical and pharmacology studies of zilovertamab needed to support a BLA submission. Study ZILO-301 will be conducted internationally in at least 50 centers with demonstrated expertise treating MCL, with initiation expected in the second quarter of 2022. The Phase 3 trial is designed to evaluate up to 250 randomized patients. We are also planning to conduct Study ZILO-302, an open-label companion clinical trial to Study ZILO-301. Patients who have progressive disease during the initial four months of ibrutinib monotherapy from Study ZILO-301 will be enrolled and treated with zilovertamab plus ibrutinib, to determine whether ROR1 inhibition can sensitize patients to ibrutinib therapy. If successful, Study ZILO-302 could result in an additional approval or label expansion for this underserved patient population. 16 Zilovertamab development in prostate cancer Prostate cancer disease overview Prostate cancer is the second most frequently diagnosed cancer among men in the U.S. behind skin cancer, according to the American Cancer Society. While patients with localized prostate adenocarcinoma have 5-year survivals that approach 100% according to the SEER Program database, outcomes are much more dismal in the metastatic setting, with an estimated 5-year survival of 30%. Much of this mortality is attributed to castrate resistant disease, in which the malignancy develops the ability to progress despite androgen deprivation or blockade. In its castrate resistant state, the disease is characterized by impaired quality of life and diminished survival. Current management strategies include hormonal and cytotoxic therapies. Though these approved therapeutic agents have slightly prolonged survival for patients with this disease, responses are not durable and nearly all patients develop resistance. Moreover, many of these therapies are not targeted and in the case of cytotoxic therapies, are associated with toxicity and poor tolerability. Despite a growing understanding of the molecular signaling associated with prostate cancer growth, there remains a paucity of targeted therapies in the management of prostate adenocarcinoma. ROR1 is expressed by approximately 90% of prostate cancers, and the Wnt5a signaling pathway is activated in patients with advanced prostate cancer that is progressing while on treatment with an AR inhibitor. Treatment of prostate cancer cell lines with an AR inhibitor was found to increase the expression of Wnt5a, and the addition of Wnt5a attenuated the antiproliferative effect of AR inhibition. The expression of Wnt5a in the tumors of patients with mCRPC has been associated with poor OS. Notably, ROR1 expression has also been shown on certain prostate cancer cell lines that had lost dependence on the AR signaling pathway, an important mechanism of resistance development in advanced prostate cancer. We are collaborating with academic investigators to investigate the potential effects of zilovertamab on this disease. Zilovertamab clinical development in prostate cancer An investigator-sponsored prospective, open-label, non-randomized, one-arm Phase 1b study to evaluate the safety and efficacy of, and to determine the recommended Phase 2 dose, or RP2D, of, docetaxel combined with zilovertamab in patients with mCRPC is about to open at UC San Diego, with an IND in effect. During the treatment period, zilovertamab and docetaxel will be administered by IV infusion on an outpatient basis. Initially, zilovertamab be given as a series of loading doses with biweekly IV infusions on days 1, 15, and 29 of cycle 1. Following this, zilovertamab will be given concurrently with docetaxel (cycles 2 up to 6 depending on tolerance to docetaxel) and each cycle will be 21 days in length. Patients will be treated for a maximum of six cycles with combination therapy. Following completion or discontinuation of docetaxel, cycle length will be 28 days and zilovertamab will be administered day 1 of every 28-day cycle starting at cycle 8 (or earlier depending on tolerance). Zilovertamab will be administered IV on day 1 of the cycle. Zilovertamab development in breast cancer Zilovertamab was evaluated in an investigator-sponsored single-arm, open-label, Phase 1b trial of zilovertamab in combination with paclitaxel in patients with locally advanced, unresectable or metastatic HER2-negative breast cancer. The primary objective of this trial was to determine the safety and tolerability during the first four weeks of fixed dose zilovertamab when administered in combination with weekly standard of care paclitaxel to patients with metastatic, or locally advanced, unresectable breast cancer. The treatment regimen was zilovertamab at a dose of 600 mg on days 1 and 15 of cycle 1, and then on day 1 of each subsequent 28-day cycle, and paclitaxel weekly at a dose of 80 mg/m2. The study was completed by UC San Diego and analyzed based on a data cutoff of August 12, 2021. Twenty-three patients were screened, and 16 were treated with paclitaxel and zilovertamab. Adverse events were consistent with the known safety profile of paclitaxel alone. There was no dose limiting toxicity, no discontinuations and no serious adverse events attributed to zilovertamab. Adverse events possibly related to zilovertamab included nausea, neutrophil count decreased, and constitutional symptoms. Among the 16 patients in the intent-to-treat population, the ORR was 37.5% (95% confidence interval 15.2% - 64.6%) with six patients experiencing PR, and the best response rate, including SD, was 75.0% (95% confidence interval 47.6% - 92.7%). 17 Additional potential clinical opportunities for zilovertamab in other solid tumors Lung cancer. ROR1 is expressed by approximately 77% to 93% of lung cancers. In adenocarcinoma of the lung, higher levels of ROR1 expression were correlated with advanced stages of disease and with positive lymph node metastases. In addition, Kaplan-Meier survival analysis indicated an association of high ROR1 expression with worse OS in lung adenocarcinoma patients. ROR1 expression has been shown to be correlated with the presence of other negative prognostic factors such as phosphorylated AKT, or p-AKT, or phosphorylated CREB, or p-CREB. Inhibition of ROR1 in lung cancer cell lines induced apoptosis and cell cycle arrest and led to a reduction in levels of p-CREB and p-AKT. Notably, a recent preclinical study has shown that downregulating ROR1 expression re-sensitizes erlotinib-resistant lung cancer cells to an EGFR inhibitor drug. Ovarian cancer. ROR1 is expressed by approximately 54% of ovarian cancers, which is the most lethal gynecologic malignancy among women worldwide. Analysis of ROR1 expression on ovarian cancer patient samples revealed that disease-free survival and OS rate in patients with high ROR1 expression were significantly lower than in patients with low or no ROR1 expression. In a preclinical study, it was shown that a ROR1 antibody inhibited growth of ovarian cancer cell lines in vitro and slowed tumor growth in a mouse model. Zilovertamab also demonstrated an anti-proliferative effect on certain ovarian and endometrial cancer cell lines in vitro. Pancreatic cancer. ROR1 is expressed by approximately 83% of pancreatic cancers. A recent preclinical study has shown that blocking ROR1 led to apoptotic cell death, which was further enhanced in combination with chemotherapeutic drugs such as erlotinib and ibrutinib, when tested against a panel of pancreatic cancer cell lines. ROR1 CAR-T Cell Therapy Program We are developing our CAR-T cell therapy candidate based on the ROR1 binding domain of zilovertamab to treat patients with aggressive hematological malignancies or solid tumors. We believe that the selective expression of ROR1 on many tumor cells and its absence on normal cells make it an ideal target for a CAR-T cell therapy approach. In addition, we believe that ROR1-negative relapses might be less likely to develop after ROR1 CAR-T cell therapy, because the survival benefit imparted on cancer cells by ROR1-associated activities may limit the development of ROR1-negative tumors, such that tumor cells that lose or mutate ROR1 to escape CAR-T cell treatment may be less aggressive than the parental cells. Our ROR1-targeting CAR-T cell therapy candidate, ONCT-808, is in preclinical development and we expect to submit to the FDA our first IND for the treatment of patients with relapsed/refractory B-cell malignancies in mid-2022. We are pursuing a two-pronged development strategy for our ROR1 CAR-T cell therapy program. The first part of the strategy is to demonstrate evidence of safety and clinical activity of our ROR1 CAR-T cell therapy in humans while seeking to reduce the development risks by using an established autologous CAR-T approach and targeting hematological indications that are known to be susceptible to CAR-T cell therapy. The second part of the strategy will be to develop next-generation cell therapies targeting ROR1 by introducing more advanced cell therapy technologies, which could include CAR-T cells bearing additional features to overcome the solid tumor microenvironment, as well as “off-the- shelf” or allogeneic CAR-T cell or CAR-NK cell therapies. We expect partnerships and collaborations to be essential for implementing our next-generation strategy. In January 2021, we announced a research and development collaboration with Karolinska Institutet to advance novel ROR1-targeting cell therapies focused on CAR-T cells and CAR-NK cells from the laboratory into the clinic. In September 2021, we announced a research collaboration with Celularity Inc., or Celularity, to evaluate placental derived- cellular therapies targeting ROR1. As part of the collaboration, Celularity will explore in preclinical studies: (i) the use of zilovertamab in combination with Celularity’s natural killer cells, and (ii) ROR1-targeted chimeric antigen receptor, or CAR, gene modification in Celularity’s CYNK natural killer cell and CyCAR-T cell platforms. 18 We are also collaborating with SPH for our CAR-T cell therapy program, through its U.S. subsidiary Shanghai Pharmaceutical (USA) Inc., or SPH USA. SPH USA entered into the SPH USA License Agreement with us to develop ROR1-targeted CAR-T cell therapy product candidates in greater China. One of SPH USA’s affiliates intends to conduct one or more initial clinical trials of the licensed ROR1 CAR-T cell therapy candidate at hospitals in China that have experience with processing cellular immunotherapy materials and conducting CAR-T cell therapy clinical trials. Scientific background: CAR-T cell therapy overview Immuno-oncology approaches to treating cancer involve redirecting one of the pillars of the immune system, the adaptive immune system, so that it specifically and efficaciously recognizes cancerous cells that might previously have escaped immune recognition. A key element in the adaptive immune response is the T cell that can recognize and kill infected and abnormal cells. T cells also act to signal other immune cells to respond to threats. T cells recognize their targets because they are selected in a way that allows them to specifically recognize foreign antigens on the surface of other cells. T cells are well suited for immuno-oncology applications based on several characteristics. They have evolved to be exquisitely specific and avid killers. One T cell can eliminate numerous target cells. T cells are extremely specific, able to recognize a cancer cell and kill it, while ignoring an almost identical healthy cell. T cells are thought to be vigilant all the time, eliminating cancer cells from the body before they can form tumors. However, tumor cells sometimes evolve to escape T cell killing by activating a number of pathways that suppress T cell function. Adoptive T cell therapies, and specifically CAR-T cells, are being developed to provide methods to generate large quantities of T cells capable of specifically recognizing and killing tumor cells despite tumor suppressive mechanisms. CAR-T cells are generated by isolating T cells from patients and modifying them to recognize specific antigens on tumors. T cells have potent cell killing activity that is directed to target cells that are recognized by specific T cell receptors, or TCRs, that are expressed on the surface of these T cells. While some T cells have TCRs that can recognize cancer cells leading to their killing, potent T cells do not develop against all tumor targets. In some cases, the potential cancer cell target is also a protein that has an essential role in other tissues or at other stages of development, and TCRs that recognize these targets are eliminated during normal T cell development. CAR-T cell therapy has emerged as a way to engineer T cells to recognize specific targets, such as those that are selectively expressed on cancer cells. A gene encoding a chimeric protein is constructed that contains a single antigen-binding domain of an antibody that specifically recognizes the target, which is coupled to a T cell costimulatory domain and a portion of the T cell receptor. CAR-T cell therapies are typically produced from a patient’s own T cells, which are isolated by leukapheresis. These cells are then genetically modified with the chimeric antigen gene construct which can be delivered by various mechanisms, such as lentiviral gene delivery vectors. Transduced cells are then expanded and undergo quality testing before being reintroduced into the same patient. This approach is also known as autologous CAR-T cell therapy. 19 Figure 8. CAR-T Production and Patient Treatment. DAARI Program ONCT-534, our lead DAARI program candidate, is a novel investigational, potentially first-in-class, orally bioavailable, AR dual-action inhibitor, for the treatment of patients with mCRPC and other AR-driven diseases. Based on preclinical studies, we believe ONCT-534 has the potential to be a novel treatment option for patients with advanced prostate cancer. We licensed ONCT-534 and certain other DAARI program rights from the University of Tennessee Research Foundation, or UTRF, under an exclusive, worldwide license agreement. Figure 9. Schematic Representation of Clinically Relevant Domains of the Androgen Receptor. We have chosen AR antagonism and degradation as our target mechanism of action focus due to the well-documented biology of AR signaling as the principal driver of prostate cancer. ONCT-534 has demonstrated activity in preclinical models of AR overexpression, AR mutations, as well as AR splice variants, all common mechanisms of resistance to current standard of care agents in advanced prostate cancer. ONCT-534 has a potentially novel and unique mechanism of action: interacting with both the NTD and LBD of the AR, inhibiting AR function as well as inducing AR protein degradation. We believe that this NTD binding is relevant to the activity of ONCT-534 against tumors expressing AR splice-variants that do not contain an LBD. Current standard of care treatment options, such as enzalutamide or apalutamide, bind only to the LBD of the AR, which may explain their reduced efficacy in patients with AR-SV-expressing tumors, as these AR variants lack the LBD. We believe that the differentiated dual-action pharmacology of ONCT-534 has the potential to translate into improved clinical outcomes over current standard of care agents. Prostate cancer overview Approximately one-third of all prostate cancer patients who have been treated for local disease with curative intent will subsequently have rising serum levels of prostate-specific antigen, or PSA, which is an indication of recurrent disease with or without development of distant metastasis. Patients with recurrent disease as indicated by rising PSA usually undergo androgen deprivation therapy, or ADT. While most of these patients initially respond to ADT, many experience a recurrence in tumor growth despite the reduction of testosterone to castrate levels, and at that point are considered to have castrate resistant prostate cancer, or CRPC. Following diagnosis of CRPC, patients have generally been treated with anti-androgens that competitively 20 block the binding of androgens (darolutamide, enzalutamide, apalutamide or bicalutamide) to the AR resulting in functional inhibition of the AR signaling pathway, or inhibit synthesis of androgens (abiraterone). More recently, significant improvements in PFS and OS have been achieved by utilizing this latest generation of antiandrogens in combination with ADT earlier in the disease natural history, such as hormone-sensitive prostate cancer, or HSPC, and non- metastatic CRPC, or nmCRPC. The growth of prostate tumors is in large part mediated by an activated AR pathway. Generally, there are three means of activating the AR. First, androgens, such as dihydrotestosterone, can activate the AR by binding to its LBD. Second, CRPC can be driven by variants of AR that lack an LBD, are constitutively activated, and consequently do not require androgens for activation. A third mechanism may involve certain signaling pathways that activate AR independent of androgen activity. Generally, current drugs for the treatment of prostate cancer are directly inhibiting activation of the AR pathway by: (i) interfering with the production of androgen, or (ii) preventing androgen from binding to the LBD. Over time, these approaches will eventually fail due to mechanisms of resistance, which involve the LBD end of the receptor, whether at the DNA level via AR amplification, or via LBD mutations, or at the RNA level via the emergence of AR splice variants. With respect to the development of alternative pathway mechanisms of AR activation, tumors might also be insensitive to antiandrogen activity. Lastly, in patients who have been treated for years with various antiandrogen therapies, genomic changes may lead to additional, non-AR-related oncogenic drivers, also insensitive to inhibition of AR pathway biology. Mechanism of Action As a DAARI, ONCT-534 has a potentially novel and unique mechanism of action: it interacts with both the NTD and the LBD of the AR (shown in the figure above), inhibiting AR function and leading to AR protein degradation. We believe that this NTD binding is relevant to the activity of ONCT-534 against tumors expressing AR splice-variants by preventing AR activation. In this respect, ONCT-534 is designed to mechanistically differ from classical non-steroid antiandrogens that interfere with androgen synthesis, such as abiraterone, and to differ from current standard of care treatment options, such as darolutamide, enzalutamide, or apalutamide, that bind only to the LBD of the AR, which may explain their reduced efficacy in patients with AR-SV- expressing tumors, as these AR variants lack the certain parts of the LBD. We believe that the potentially differentiated dual-action pharmacology of ONCT-534 has the potential to translate into significantly improved clinical outcomes over current standard of care agents. We believe our mechanism of action offers potential for DAARI therapeutic development in other AR-driven diseases, such as luminal AR-positive triple-negative breast cancer, or LAR-TNBC, as well as non-oncology indications, such as Spinal Bulbar Muscular Atrophy, or SBMA. ONCT-534 development in prostate cancer We are evaluating ONCT-534 as a potential therapy for patients with advanced CRPC and other AR-driven diseases. In preclinical studies, ONCT-534 demonstrated antagonism and degradation of full-length AR, mutant LBD AR, and AR-splice variants. ONCT- 534 additionally has shown strong in vivo activity in models of prostate cancer in both castrated and intact animals that are resistant to AR antagonists, such as enzalutamide, as detailed below. To assess the ability of ONCT-534 to treat enzalutamide-resistant cancers, we conducted in vivo studies in an enzalutamide-resistant MDVR VCaP cell line xenograft model. This treatment resistance can be seen in the figures below for both castrated and intact animals, as tumors in mice dosed with enzalutamide grew at nearly the same rate as tumors in mice dosed only with the drug vehicle, a control similar to dosing with a placebo. Orally delivered ONCT-534 significantly inhibited tumor growth, described as tumor growth inhibition, or TGI, in these enzalutamide-resistant MDVR tumors. 21 Figure 10. DAARIs Exhibit AR-specific Anti-tumor Activity in ENZA-resistant Preclinical Model. In a mouse xenograft model of human prostate cancer in intact animals, tumor growth of LnCAP human prostate cancer cells that overexpress AR (LnCAP-AR) was significantly inhibited by treatment with ONCT-534, as shown in the figure below. Figure 11. DAARIs Exhibit AR-specific Anti-tumor Activity in AR-overexpressing Preclinical Model. AR-V7 is a splice variant of AR that lacks the LBD and hinge region and is expressed in 22Rv1 cells, which are human prostate carcinoma epithelial cells derived from a xenograft that was serially propagated in mice after castration-induced regression and relapse of the parental, androgen- dependent xenograft. As shown in the figure below, enzalutamide is not efficacious against these tumors that lack the LBD. Treatment with ONCT-534 however, resulted in tumor growth inhibition as well as significant reduction in PSA in this model, demonstrating activity at the NTD. 22 Figure 12. DAARIs Exhibit Anti-tumor Activity in AR Splice-variant Preclinical Model. Preclinical IND-enabling activities are ongoing for ONCT-534. The manufacturing process has been established and transferred to the lead manufacturer. We are also evaluating potential Phase 1/2 clinical study designs to demonstrate safety, determine the RP2D and efficacy, including the effect on patient PSA levels of ONCT-534 in patients with relapsed or refractory mCRPC regardless of their mutational status. ONCT-216 - ETS oncoprotein inhibitor ONCT-216 is an investigational, potentially first-in-class, targeted small-molecule inhibitor of the ETS family of oncoproteins, including fusion proteins. Tumorigenic fusion proteins involving the EWS protein and an ETS protein can be found in virtually all cases of Ewing sarcoma. ETS-related translocations or overexpression are also found in many other tumors, such as DLBCL, prostate cancer and AML. Researchers in the laboratory of one of our scientific advisors, Jeffrey Toretsky, M.D. of Georgetown Lombardi Comprehensive Cancer Center, identified the precursor to ONCT-216 by using a novel chemical screening assay that they developed based on a deep understanding of the underlying biological mechanism of ETS factors. Following this early work, ONCT-216, which is designed to be a specific, high-affinity inhibitor of ETS factors, was created by us through the rational design and screening of novel small molecule inhibitors of a critical protein-protein interaction. In preclinical models, ONCT-216 has inhibited the interaction between ETS family members and RNA Helicase A, RHA and by doing so, shut down excessive cell proliferation. We are evaluating ONCT-216 as a single agent and in combination with vincristine, in heavily pretreated patients in a Phase 1/2 clinical trial in patients with relapsed or refractory Ewing sarcoma. The dose-finding portion of the study was completed in 2019. We completed enrollment of the Phase 2 expansion cohort to evaluate the clinical response of treatment with ONCT-216 in combination with vincristine using the RP2D regimen, and we are currently enrolling patients in a new Phase 2 expansion cohort to evaluate clinical responses to single agent ONCT-216 using an optimized dosing regimen, treating patients for 28 days per cycle with the next cycle starting immediately after the prior one, to intensify the amount of ONCT-216 administered over time. Ewing sarcoma is a rare pediatric cancer that has historically been very challenging to treat effectively, particularly for recurrent and metastatic disease. The FDA has granted rare pediatric disease designation, as well as orphan drug and fast track designations for ONCT-216 for the treatment of Ewing sarcoma. ONCT-216 scientific background: ETS transcription factors and oncogenesis ONCT-216 targets the ETS family of oncoproteins known to be associated with both solid tumors and hematological malignancies. In normal development and physiology, ETS transcription factors govern processes such as cell cycle control, differentiation, proliferation, apoptosis, tissue remodeling and angiogenesis. However, when alterations in the functions of ETS factors develop, through overexpression, gene fusion or modulation, they have been shown to lead to tumor initiation, progression, and metastasis. Fusion proteins are a well-known category of targets for small molecule cancer therapy that have been cited in the scientific literature as providing a number of diagnostic and therapeutic advantages because of their tumor-specific expression. Fusion proteins involving ETS factors have been implicated in various solid tumors, including Ewing sarcoma and prostate cancer. For example, approximately 85% of Ewing sarcomas contain a genomic 23 rearrangement between chromosomes 11 and 22. DNA is exchanged between these chromosomes in a pathological manner, and this exchange results in a fusion of two genes: the FLI1 gene, an ETS family member, and the EWSR1 gene, an unrelated transcription factor. This gene fusion, known as EWS/FLI1, functions as a transcription activator that is no longer controlled by the relevant regulatory machinery in the cell. In addition to escaping regulation, the dysregulated function of the resultant EWS/FLI1 fusion protein causes a series of abnormalities in RNA processing including aberrant mRNA expression and splicing, where it leads to defects in the synthesis of proteins, such as BRCA1, a DNA repair protein. EWS/FLI1 fusion proteins also cause the formation of abnormal and potentially deleterious DNA and RNA structures known as R-loops that are associated with replication and transcriptional blocks as well as being prone to increased DNA damage. Multiple other tumors contain gene fusions of other ETS factors. For example, over 50% of metastatic prostate cancers carry a TMPRSS2-ETS gene fusion. Other tumors have genetic changes that result in overexpression of ETS factors. ETS Fusions ETS Overexpression • Ewing sarcoma • EWS-FLI1 • Prostate cancer • TMPRSS2-ERG • AML • ETV6-various (20+) • ALL • ETV6-RUNX1 • Secretory breast cancer • ETV6-NTRK3 • AML • FLI1, ERG, ETV5, ETS2 • DLBCL • • • • ETV1, FLI1, ETV4, SPIB Prostate cancer • ERG, ETV1, ETV4, ETV6 Lung cancer • ETV5, ETV1, FLI1, ETS1 Breast cancer • ETV6, ETV4, SPIB, ETV5 Despite the genetic associations between ETS factors and tumorigenesis and the reported correlation between high levels of ETS factor expression and survival, there are currently no approved therapeutics available that target these factors. We believe that our approach of inhibiting protein-protein interactions is novel and that our product candidate ONCT-216 targeting ETS factors could fill an important gap in the treatment landscape for both solid tumors and hematological malignancies. ONCT-216 development in Patients with Ewing sarcoma Ewing sarcoma disease overview Ewing sarcoma is the second most common bone tumor of children, and it occurs most often in adolescents, accounting for approximately 2% of all childhood cancer diagnoses. The incidence of Ewing sarcoma for all ages is approximately 1.3 cases per 1 million people in the U.S., corresponding to approximately 430 new patients diagnosed per year in the U.S. The median age at diagnosis of patients with Ewing sarcoma is 15. Nearly all Ewing sarcoma cases are driven by translocations of ETS family oncogenes, including 85-90% of cases driven by the EWS-FLI1 fusion, and approximately 10% by EWS-ERG. Ewing sarcoma typically develops in the pelvis, femur, and bones of the head and trunk, but its diagnosis often takes months as other causes for non-specific symptoms such as localized pain, fever, fatigue, weight loss, or anemia are ruled out. The five-year survival of patients who are diagnosed with non-metastatic disease is between 50% and 70%. Patients diagnosed with metastatic disease have five-year survival between 18% and 30%. The prognosis for patients with recurrent Ewing sarcoma is particularly poor, and five-year survival after recurrence is approximately 10 to 15%. Ewing sarcoma is usually treated systemically due to the fact that local treatments, even in patients without overt metastases, have an 80% to 90% relapse rate. The current standard therapy for patients with localized Ewing sarcoma in the U.S. is a combination of chemotherapy agents, including vincristine, 24 doxorubicin and cyclophosphamide, with alternating cycles of ifosfamide and etoposide – a therapy known as VDC/IE. Patients that respond to this therapy may be candidates for tumor resection and continued treatment for a total of 14 to 17 cycles. This therapeutic regimen, however, is associated with significant toxicities. Patients with metastatic disease are often treated with VDC/IE or variations of this therapy with higher or more compressed dosing. This may also be supplemented by local radiation therapy or systemic radiation followed by autologous hematopoietic stem cell transplant. We believe that more effective therapies are needed for this rare and severe pediatric disease. ONCT-216 preclinical data in Ewing sarcoma ONCT-216 was the product of a novel approach based on developing small molecule inhibitors of a critical protein-protein interaction linked to the ETS family of transcription factors. Researchers at Georgetown University identified YK-4-279, the precursor to ONCT-216, by using a novel chemical screening assay. Following this early work, ONCT-216, a specific inhibitor of ETS factors, was then created by Oncternal through the rational design and screening of novel small molecule inhibitors of a critical protein-protein interaction linked to the ETS family of transcription factors. ONCT-216 is a structural analog of YK-4-279 that has shown increased potency in biochemical, cellular and xenograft tumor models. Figure 13. ONCT-216 Inhibits Interaction of ETS Fusion Protein EWS/FLI1 with RHA. In Ewing sarcoma, a key heterodimer between EWS/FLI1 and RHA forms the core of a transcriptome complex causing activated oncogenes, inhibited tumor suppressors, abnormal RNA transcription and abnormal RNA splicing. ONCT-216 was developed to disrupt that heterodimer, thereby potentially preventing transcription and leading to inhibition of the oncogenic activity of EWS/FLI1, by decreasing oncogene expression, increasing tumor suppressor function, and apoptotic cell death. In preclinical models, ONCT-216 inhibited the interaction between ETS family members and RHA and by doing so, shut down excessive cell proliferation and caused apoptotic cell death. ONCT-216 clinical development in Ewing sarcoma We are evaluating ONCT-216 as a single agent and in combination with vincristine in an open-label, multicenter Phase 1/2 clinical trial in patients with relapsed or refractory Ewing sarcoma. Ewing sarcoma is a rare pediatric cancer that has historically been very challenging to treat effectively, particularly for recurrent and metastatic disease. ETS fusion proteins have been shown to be present in over 90% of Ewing sarcoma cases. The dose escalation portion of the study was completed in 2019, and we completed enrollment of the Phase 2 expansion cohort to evaluate the clinical response of treatment with ONCT-216 in combination with vincristine using the RP2D regimen. The RP2D for the combination had been established to be 200 mg/m2/day of ONCT-216 for 14 days, with vincristine 0.75-1.5 mg/m2 on the first day of each 28-day treatment cycle. In November 2021, we announced updated interim clinical data from our ongoing open-label, multicenter Phase 1/2 clinical trial evaluating ONCT- 216 in patients with relapsed or refractory Ewing sarcoma. Patients entering the trial had previously been treated with a median of three, and as many as nine prior lines of systemic therapy. The presentation included interim data for 60 evaluable patients, including 37 evaluable patients treated at the RP2D as of the October 1, 2021 efficacy cutoff date. Two of the 37 patients treated at the RP2D (5.4%) achieved a CR. One patient achieved a CR after resection of a residual non-target lung lesion at Cycle 6 and completed >2-years of treatment with no evidence of disease, and one patient remains on treatment with no evidence of disease at 25 >20 months on study as of the cutoff date. The best ORR was 8.1% for patients treated with RP2D. Twelve additional patients treated at the RP2D had SD, for a disease control rate (CR, PR or SD) of 40.5%. The median duration of response for patients treated at the RP2D was 14.7 months. In the third quarter of 2021, we added a new Phase 2 expansion cohort targeting up to 21 Ewing sarcoma patients to evaluate clinical responses to single agent ONCT-216 at 175 mg/m2/day, treating patients for 28 days per cycle with the next cycle starting immediately after the prior one, to intensify the amount of ONCT-216 administered over time. The new Phase 2 expansion cohort is actively enrolling patients. Results from the CTOS 2021 Annual Meeting presentation for patients with relapsed or refractory Ewing sarcoma treated with ONCT-216 as a single agent and in combination with vincristine are shown in the figures below. Figure 14. ONCT-216 Patient Overview: Swimmer’s Plot. In the fourth quarter of 2022, we expect to announce additional interim clinical data from this Phase 1/2 clinical trial in patients with Ewing sarcoma, including data from the expanded cohort with the intensified dosing regimen. Potential additional clinical opportunities for ONCT-216 Diffuse Large B-Cell Lymphoma, or DLBCL. DLBCL is a form of non-Hodgkin lymphoma, or NHL, that is the most common blood cancer. Lymphomas occur when cells of the immune system grow and multiply uncontrollably. B cells are a type of lymphocyte that is responsible for producing antibodies. DLBCL occurs mostly in adults and is a fast-growing (aggressive) B-cell lymphoma. It can start in the lymph nodes or outside of the lymphatic system in the gastrointestinal tract, testes, thyroid, skin, breast, bone, or brain. Often, the first sign of DLBCL is a painless rapid swelling in the neck, armpit, abdomen, or groin caused by enlarged lymph nodes. For some people, the swelling may be painful. Other symptoms include night sweats, unexplained fevers, and weight loss. ETS transcription factors have been implicated in the development of lymphoid tissues and immune system control. ETS1 and FLI1 have been shown to regulate important mechanisms in B-cell development and maturation, such as the B-cell specific activator PAX5 as well as the regulator of plasma cell differentiation, PDRM1. DLBCL 26 is the most common subtype of NHL that has been shown to have high expression of these transcription factors. Nearly one-quarter of 166 DLBCL cases were characterized by a recurrent lesion on chromosome 11q24.3, which contains the transcription factors ETS1 and FLI1. In a published report, ONCT- 216 demonstrated anti-lymphoma activity in vitro and in vivo when used either alone or in combination with certain other lymphoma therapies, including venetoclax or lenalidomide. Notably, ONCT-216 was administered orally in the in vivo studies suggesting the potential for an oral dose development. Prostate cancer. Approximately 174,650 new cases of prostate cancer are diagnosed annually in the U.S. The incidence of metastatic prostate cancer is increasing, causing an estimated 31,620 deaths per year in the U.S. New therapeutic options are needed after failure of androgen antagonism and prior to chemotherapy. Approximately 55% of men with advanced prostate cancer carry the ETS family fusion gene TMPRSS2-ERG that is related to androgen resistance. We believe ONCT-216 may provide a novel therapeutic strategy for the treatment of patients with advanced prostate cancer, in particular those who carry the ETS family fusion gene TMPRSS2-ERG. In a preclinical in vivo study, YK-4-279, which is an analog of ONCT-216, showed anti-tumor activity against a prostate cancer cell line harboring the ETS-family translocation, while growth of a prostate cancer cell without the translocation was not inhibited. Acute myeloid leukemia, or AML. AML is a hematologic malignancy characterized by dysregulated maturation of myeloid or blood stem cells and failure of the bone marrow to properly function, leaving patients with anemia and immune deficiency, and at high risk of infections and bleeding. AML is the most common type of acute leukemia in adults. Approximately 21,450 new AML cases and 10,920 AML associated deaths occur annually in the U.S. The average age of an AML patient is 68 years. The National Cancer Institute estimated in 2018 that the five-year survival rate for adult patients with AML was approximately 27%. We believe that there is a need for more effective and less toxic therapies for AML. ETS overexpression or fusion proteins incorporating ETS family member have been observed in about 30% of AML cases. The ETS family member ERG is overexpressed in many cancers, such as AML. In a retrospective analysis of patients with AML, the quartile of patients with the highest levels of ERG expression had a significantly higher rate of relapse and poorer OS than patients with lower levels of ERG expression. Those with the highest levels of ERG had a five-year survival rate of 20%, while those with lower levels of ERG had a survival rate of approximately 50%. ERG overexpression was an independent negative prognostic factor. Similarly, AML patients with high levels of ETS2, another ETS family member, had a significantly lower five-year survival rate of approximately 15% compared to 40% for patients with lower levels of ETS2. ETS2 overexpression was an independent negative prognostic factor. Figure 15. Survival of Patients with AML is Related to Expression of ETS Oncoproteins ERG (left) or ETS2 (right). Multiple AML cell lines have been shown to be sensitive to being killed by ONCT-216, with sensitivity proportional to ETS expression. ONCT- 216 may provide a novel therapeutic strategy for the treatment of patients with relapsed and refractory AML, a patient population known to express, in certain cases, fusion proteins involving ETV6, and to have overexpression of ETS family members including FLI1, ERG, ETS2, and ETV5. 27 Figure 16. Prostate Cancer Sensitivity was Associated with an ETS-family Fusion Protein in Human Prostate Cancer Xenograft Models. Competition The biotechnology and pharmaceutical industries are intensely competitive and characterized by rapid technology evolution. Our potential competitors include large pharmaceutical, specialty pharmaceutical and biotechnology companies, as well as government, academic and other research institutions. Many of our competitors 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. Smaller or 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, as well as in acquiring technologies complementary to our programs. Our commercial opportunities may be reduced or eliminated if our competitors develop and commercialize similar products that are safer, more effective, have fewer side effects or are less expensive than any products that we or our collaborators may develop. In particular, we compete with other companies that are developing and commercializing treatments for patients with cancer. Competing therapies include chemotherapies, targeted therapies and immunotherapies and may represent various therapeutic modalities including small molecules, antibodies, cell therapies, gene therapies, and cancer vaccines. These companies may compete with us for clinical trial sites and eligible patient populations, scientific and management talent, outsourced manufacturing capacity and healthcare budgets for commercial-stage products. Zilovertamab competition There are several therapeutic options available to treat patients with relapsed or refractory MCL, including BTK inhibitors. In an open-label Phase 2 clinical trial, ibrutinib (Imbruvica), a BTK inhibitor that is approved by the FDA for the treatment of patients with relapsed MCL, demonstrated an ORR of 66% and a CR rate of 17%, with a median DOR of 17.5 months. In an open-label Phase 2 clinical trial, acalabrutinib (Calquence), another BTK inhibitor approved by the FDA for the treatment of patients with relapsed MCL, demonstrated an ORR of 80% and CR rate of 40%. Another BTK inhibitor approved in 2019, zanubrutinib (Brukinsa), demonstrated an ORR of 84% and CR rate of 59%, with a median DOR of 19.5 months in an open-label Phase 2 clinical trial. These therapies are given continuously for prolonged periods of time, and their use can be associated with significant toxicity. The majority of patients with MCL are older, and remissions are not durable with most patients relapsing in less than 20 months. As a result, we believe that more effective and better tolerated therapies with shorter treatment periods represent a significant unmet need. Three classes of targeted therapies have been approved for the treatment of patients with CLL: inhibitors of BTK, a key component of cell signaling in B-cells, such as ibrutinib, which is marketed as Imbruvica by AbbVie, Inc., and Johnson & Johnson, and acalabrutinib, which is marketed as Calquence by AstraZeneca PLC; inhibitors of the protein B-cell lymphoma-2, or Bcl-2, such as venetoclax, which is marketed as Venclexta and Venclyxto by AbbVie, Inc., and Roche/Genentech; and inhibitors of Phosphoinositide 3-kinase, or PI3K, which include idelalisib, which is marketed as Zydelig by Gilead Sciences, Inc., and duvelisib, which 28 is marketed as Copiktra by Verastem, Inc. These targeted therapies are now the core of the recommended treatment regimens for patients with both first- line and relapsed or refractory CLL, and have achieved objective response rates of 85-90%, two-year PFS of 65-90%, and two-year overall survival of 75- 95%. The outcomes are worse for patients with certain prognostic factors, such as 17p or 11q chromosome deletions; for such patients with relapsed or refractory CLL treated with ibrutinib, the reported PFS is 50-75%. While there are currently no approved products targeting the ROR1 receptor, we are aware of therapeutics in clinical development that target ROR1, including MK-2140, an ADC being developed by Merck & Co., an ADC being developed by NBE-Therapeutics (acquired by Boehringer Ingelheim in 2020), and a ROR1 CAR-T therapy being developed by Bristol-Myers Squibb Company. MK-2140, originally designed and developed by Oncternal, binds to the same epitope on ROR1, and utilizes zilovertamab to target ROR1. There are numerous companies developing or marketing treatments for the same oncology indications that we are targeting with our zilovertamab program. Therapies approved or in clinical development for the treatment of patients with treatment-naïve or relapsed/refractory CLL and relapsed/refractory MCL include BTK inhibitors, Bcl-2 inhibitors, PI3K inhibitors, anti-CD20 antibodies, and cell therapies that are being marketed or developed by companies including AbbVie, Inc., AstraZeneca PLC, BeiGene, Ltd., Eli Lilly and Company, Gilead Sciences, Inc., Johnson & Johnson, MEI Pharma, Merck, Novartis Pharmaceuticals Corporation, Roche Holding AG’s Genentech subsidiary, TG Therapeutics, Inc., and Verastem, Inc. ROR1 CAR-T competition While there are currently no approved cell therapy products targeting the ROR1 receptor, we are aware of an autologous CAR-T cell therapy clinical program targeting ROR1 sponsored by Bristol-Myers Squibb for patients with hematological malignancies. Precigen, Inc. announced plans to initiate a Phase 1/1b clinical trial of PRGN-3007, an autologous CAR-T cell therapy targeting ROR1, in patients with hematological malignancies and solid tumors. There are numerous companies developing or marketing cell therapy treatments for the same oncology indications that we may target with our ROR1 CAR-T program including AbbVie, Inc., Adicet, Allogene Therapeutics, Atara Biotherapeutics, Inc., Bluebird Bio, Inc., Bristol-Myers Squibb, Caribou Therapeutics, Fate Therapeutics, Gilead Sciences, Inc., Johnson & Johnson, Legend Biotech, Merck, NantKwest, Nkarta Therapeutics, Novartis Pharmaceuticals Corporation, Poseida Therapeutics, Roche Holding AG, and others. Six CAR-T cell therapies have been approved by the FDA, Yescarta and Tecartus are marketed by Gilead Sciences, Inc., Kymriah is marketed by Novartis Pharmaceuticals Corporation, Abcema and Breyanzi are marketed by Bristol-Myers Squibb Company, and Carvykti, developed by Legend Biotech. Yescarta, Tecartus, Kymriah and Breyanzi target the CD19 protein, a protein expressed on the surface of the majority of B cells, including B cell tumorigenic cells. ONCT-534 competition While there are currently no approved drugs with similar mechanism of action as our DAARI program, ONCT-534, the competition in the advanced prostate cancer market is very high. Several therapies have already been approved and many more are currently in development. Second- generation antiandrogens including Xtandi (Astellas and Pfizer), Zytiga/Erleada (Johnson & Johnson), and Nubeqa (Bayer) have become the preferred regimens for first line therapy in this indication. Other therapeutic modalities, such as checkpoint inhibitors are being evaluated in combination with either antiandrogen or chemotherapies. Bispecific antibodies and CAR-T therapies targeted towards prostate-specific member antigen are also in early development. Other approaches to interfering with AR signaling include strategies to: (i) blocking AR activation via NTD binding as being pursued by ESSA Pharma, Inc., and (ii) degrading the AR such as that being pursued by Arvinas, Inc. ONCT-216 competition 29 While there are currently no approved drugs targeting ETS oncoproteins, there are numerous companies developing or marketing treatments for the same oncology indications that we are targeting with our ONCT-216 program. Investigational therapies in clinical development for the treatment of patients with relapsed/refractory Ewing sarcoma include kinase inhibitors, LSD1 inhibitor and other targeted therapies, therapeutic antibodies and cell therapies that are being developed by companies including Bayer AG, Bristol-Meyers Squibb Company, Eisai Co., Ltd., Epizyme, Inc., Gradalis, Inc., Eli Lilly and Company, Johnson & Johnson, Exelixis, Inc., NantCell, Inc., Pharmamar S.A., Pfizer, Inc., Salarius Pharmaceuticals, Inc., Takeda Pharmaceutical Company Limited, and others.

Either party may terminate the SPH USA License Agreement in its entirety or on a licensed product-by-licensed product basis upon material breach that is not cured within 90 days, or in its entirety the event the other party becomes insolvent or enters into bankruptcy proceedings. We may terminate the agreement with 60 days written notice if SPH USA or its affiliates or sublicensees commence an action challenging the validity or enforceability of any licensed patent, or with 10 days written notice if SPH USA fails to own at least 20% of the voting securities of any assignee of the SPH USA License Agreement. Upon termination of the agreement for any reason all rights and licenses granted to SPH USA under the agreement will terminate, and in the event of termination for reasons other than our material breach, SPH USA would 31 grant us non-exclusive, royalty-free, worldwide license to any intellectual property rights controlled by SPH USA or its affiliates to exploit the terminated program in the SPH USA Territory. University of Tennessee Research Foundation (“UTRF”) In March 2015, we entered into a license agreement with UTRF (the “DAARI License Agreement”), which was amended and restated in March 2022. Under the DAARI License Agreement, we were granted exclusive worldwide rights in all proprietary DAARI technologies owned or controlled by UTRF, including all improvements thereto. We are obligated to use commercially reasonable efforts to develop and commercialize one or more licensed products, including by achieving a certain milestone event. We are obligated to pay UTRF annual license maintenance fees in the mid five digits and low single-digit royalties on aggregate net sales of licensed products. We are also obligated to pay UTRF tiered royalties ranging from a low single digit to low double digit percentage of consideration received by our sublicensees, excluding royalties, such percentage dependent on the stage of development of a clinical product candidate at the time it is sublicensed. Our obligation to pay UTRF royalties expires on a country-by-country and licensed product-by- licensed product basis on the last-to-expire valid patent claim of a licensed patent covering such licensed product in such country. Unless terminated earlier, the term of the DAARI License Agreement will continue, on a country-by-country basis, until the expiration of the last- to-expire valid claim of any licensed patent covering a licensed product in such country. Either party may terminate the DAARI License Agreement for the other party’s uncured material breach, subject to certain notice and cure periods. UTRF may terminate the DAARI License Agreement for our bankruptcy or insolvency. We may terminate the Amended and Restated UTRF Agreement with advance written notice to UTRF, provided we have satisfied our payment obligations to UTRF prior to such termination. Manufacturing We have adopted a manufacturing strategy of contracting with third parties to manufacture API, drug substance and drug product in accordance with current Good Manufacturing Practices, or cGMPs, and additional manufacturers are used to label, package and distribute investigational drug products. This strategy allows us to maintain a more flexible infrastructure while focusing our expertise on the development of our products. We expect to continue to rely on third parties for the production, characterization, and release testing of clinical and commercial quantities of all product candidates and associated critical reagents. For example, we are working with Lentigen on lentivirus manufacturing and Miltenyi Biotec B.V. & Co. KG on cell processing for our ONCT-808 program. There are no unusually complicated biochemistries or equipment required in the manufacturing process for zilovertamab, ONCT-808, ONCT-534 or ONCT-216, which we believe allows for potential manufacturing flexibility. We have established a quality control and quality assurance program, which includes a set of standard operating procedures and specifications designed to ensure that our products are manufactured in accordance with cGMPs, and other applicable domestic and foreign regulations. Intellectual Property We strive to protect and enhance the proprietary technology, inventions, and improvements that are commercially important to our business, including seeking, maintaining, and defending patent rights, whether developed internally or acquired or licensed from third parties. Our policy is to seek to protect our proprietary position by, among other methods, filing patent applications in the U.S and in jurisdictions outside of the U.S. related to our proprietary technology, inventions, and improvements that are important to the development and implementation of our business. We also rely on trade secrets and know-how relating to our proprietary technology, continuing innovation, and acquisition and in-licensing opportunities to develop, strengthen, and maintain our proprietary position in the field of cancer therapeutics. Our commercial success may depend in part on our ability to: (i) obtain and maintain patent and other proprietary protection for our technology, inventions, and improvements; (ii) preserve the confidentiality of 32 our trade secrets; (iii) defend and enforce our proprietary rights, including our patents; and (iv) operate without infringing the valid and enforceable patents and other proprietary rights of third parties. We have developed, licensed and acquired numerous patents and patent applications and possess substantial know-how and trade secrets relating to the development and commercialization of healthcare products and services. As of February 4, 2022, our owned and in-licensed patent portfolio consisted of approximately 42 issued U.S. patents and 42 pending U.S. patent applications related to certain of our proprietary technology, inventions, and improvements, and 57 issued patents and 66 pending patent applications in jurisdictions outside of the U.S. ROR1 Program We have an exclusive, commercial, worldwide, transferrable license to a portfolio of patents and patent applications directed to ROR1 antibodies and CAR-T therapies for all therapeutic indications. This portfolio is licensed from the Regents of the University of California. We have know-how and trade secrets related to compositions of matter for treating cancers, methods for treating cancer, and methods of screening for additional compositions of matter used for treating cancer, as well as to additional antibodies and molecules that modulate ROR1 signaling. We have also developed certain patents and patent applications directed to ROR1 based therapies, which are owned by Oncternal. As of February 4, 2022, our licensed patent portfolio included patents related to our zilovertamab clinical candidate currently in Phase 1 and Phase 2 clinical trials. Zilovertamab is a humanized monoclonal antibody that specifically binds to the ROR1 receptor. We have two issued U.S. patents directed to the zilovertamab composition of matter: U.S. Pat. No. 9,217,040, with a patent term not due to expire before 2032; and U.S. Patent No. 9,758,591, with a patent term not due to expire before March 2033. We have one patent issued in the U.S. directed to methods of using zilovertamab to treat cancer, U.S. Pat, No. 10,344,096, with a patent term not due to expire before March 2033. We have one patent application pending in the U.S. related to single chain variable region fragments derived from zilovertamab which, if issued, would have a patent term not due to expire before 2033. We also have patents issued in Australia, China, Europe, Israel, Japan, Korea, Macao, Canada and Mexico directed to zilovertamab compositions of matter. In Europe patents directed to zilovertamab compositions of matter have been validated in jurisdictions including France, Germany, Italy, UK, Spain, Turkey, Belgium, Poland, Netherlands, Greece, Switzerland, Sweden, Austria, Denmark, and Ireland. We have applications pending in foreign jurisdictions related to zilovertamab compositions of matter and methods of use in treating cancer, including Australia, China, Europe, Japan, Mexico, and Thailand. Patents, if issued from these pending foreign applications, would not be due to expire before 2033. The validity of one of our issued European patents EP Patent No. 3604339 is being challenged in an opposition proceeding. This patent is directed to methods of treating cancer using antibodies that bind to the epitope bound by zilovertamab. We believe we have meritorious defenses against the opposition. As of February 4, 2022, we have approximately 29 licensed patent applications pending in the U.S. and in jurisdictions outside the U.S. related to methods of treating cancer using a combination of zilovertamab and small-molecule chemotherapeutics. We have one issued patent, U.S. Patent No. 10,688,181, directed to methods of treating cancer with the combination of zilovertamab and a BTK inhibitor. Patents, if issued from these pending non- provisional applications, would not be due to expire before dates ranging from 2037 to 2041. As of February 4, 2022, we have licensed patents and patent applications related to additional ROR1 binding antibodies, polypeptides, chimeric antigen receptors, and nucleic acids encoding such non-zilovertamab ROR1 binding antibodies, polypeptides, and chimeric antigen receptors.

We have two patent applications pending in the U.S. related to additional non-zilovertamab ROR1 binding antibodies, polypeptides, chimeric antigen receptors, and nucleic acids encoding such non-zilovertamab ROR1 binding antibodies, polypeptides and chimeric antigen receptors, which, if issued, would have a patent term not due to expire before dates ranging from 2031 to 2032. We also have patents issued in Europe and Canada directed to additional ROR1 binding antibodies. We have one patent application pending in Europe related to additional ROR1 binding antibodies specific for ROR1. Any patent issued from this pending foreign application, would not be due to expire before 2032. As of February 4, 2022, we have licensed patents and patent applications related to methods of screening for antibodies that specifically bind to ROR1. We have two issued U.S. patents, U.S. Pat. Nos. 9,523,695, and 9,933,434, with patent terms not due to expire before January 2032, directed to methods of screening for antibodies that specifically bind to ROR1. We additionally have one issued U.S. patent and one patent application issued in Japan directed to methods of screening for modulators of ROR1 signaling; additionally, we have applications pending in the U.S., Australia, Canada, China, Hong Kong, and Europe directed to methods of screening for modulators of ROR1 signaling. As of February 4, 2022, we also own one patent application filed under the Patent Cooperation Treaty directed to methods of treating cancer using a combination of zilovertamab and small molecule cancer chemotherapeutics. DAARI Program We have exclusive worldwide rights to a portfolio of patents and patent applications related to Dual-Action Androgen Receptor Inhibitor, or DAARI, compounds for use in therapeutics. We hold a portfolio of patents and patent applications related to DAARIs and jointly owned with UTRF, including ten issued U.S. patents directed to DAARI ligands and methods of use thereof: U.S. Pat. No. 9,814,698, U.S. Pat. No. 10,017,471, U.S. Pat. No. 10,035,763, U.S. Pat. No. 10,441,570, U.S. Pat. No. 10,865,184, U.S. Pat. No. 9,815,776, U.S. Pat. No. 9,834,507, U.S. Pat. No. 10,093,613, U.S. Pat. No. 10,597,354, and U.S. Pat. No. 10,806,720, as well as six issued patents in Australia, Japan, China, Europe (validated in Great Britain, France and Germany) and Russia, and approximately three pending U.S. patent applications and nine pending patent applications outside of the U.S., each with a patent term not due to expire before April 2036. We also have a portfolio of patents and patent applications licensed from UTRF including five issued U.S. patent directed to DAARI ligands and methods of use thereof: U.S. Pat. No. 10,314,797, U.S. Pat. No. 10,654,809, U.S. Pat. No. 10,806,719, U.S. Pat. No. 11,230,523, and U.S. Pat. No. 11,230,531, issued patents in Japan and Israel, two pending U.S. patent applications and thirteen patent applications outside of the U.S., each with a patent term not due to expire before June 2037. A third portfolio for the DAARI program includes approximately thirteen patent applications licensed from UTRF including two pending patent applications in the U.S. and eleven pending patent applications outside of the U.S. Individual patents extend for varying periods of time, depending upon the date of filing of the patent application, the date of patent issuance, and the legal term of patents in the countries in which they are obtained. Generally, patents issued for applications filed in the U.S. are effective for 20 years from the earliest effective and non-provisional filing date. The patent term may be adjusted to compensate for delayed patent issuance when such delays are caused by the patent office or successful appeals against patent office actions. There is no limit on this patent term adjustment. In addition, in certain instances, a patent term can be extended to recapture a portion of the term effectively lost as a result of the FDA regulatory review period. The extended restoration period cannot be longer than five years and the total patent term, including the restoration period, must not exceed 14 years following the date of FDA approval of the applicable drug product. The duration of patents outside of the U.S. varies in accordance with provisions of applicable local law, but typically is also 20 years from the earliest effective non-provisional filing date. Our issued patents are due to expire on dates ranging from 2026-2037. If patents are issued on our pending patent applications, the resulting patents would be due to expire on dates ranging from 2026-2041. However, the actual protection afforded by a patent varies on a product-by-product basis, from country-to-country, and depends upon many factors, including the type of patent, the scope of its coverage, the availability of regulatory-related extensions, the 34 availability of legal remedies in a particular country, and the validity and enforceability of the patent. Most countries require a patent owner to pay maintenance fees or annuities in order to extend the patent to the full length of its term. If these fees and annuities are not paid timely, our patents will expire prior to the expiration date. ONCT-216 Program We have exclusive worldwide rights to a portfolio of patents and patent applications related to small molecules, including ONCT-216, targeting EWS-FLI1 for use in therapeutics and companion diagnostics. We hold a portfolio of patents and patent applications, the Oncternal Portfolio, related to ONCT-216, analogs thereof, and uses thereof, as well as the Georgetown Licensed Portfolio, which is licensed from Georgetown University. As of February 4, 2022, the Oncternal Portfolio directed to the new chemical entity ONCT-216 contained approximately eight U.S. issued patents and two pending applications in the U.S., as well as approximately 14 patents and approximately 21 pending patent applications in jurisdictions outside of the U.S. As of February 4, 2022, we had two U.S. patents directed to ONCT-216: U.S. Pat. No. 9,604,927, with a patent term not due to expire before October 2035, and U.S. Pat. No. 9,987,251, with a patent term not due to expire before October 2035.

The Georgetown Licensed Portfolio contained additional patents related to methods of treating cancers. We had one issued U.S. patent directed to methods of treating lung cancer or glioblastoma multiforme: U.S. Pat. No. 9,511,050, with a patent term not due to expire before October 2034. There were approximately two patents issued outside the U.S. in China and Japan. These patents have a patent term not due to expire before October 2034. Government Regulation Government authorities in the U.S., at the federal, state and local level, and other countries extensively regulate, among other things, the research, development, testing, manufacture, quality control, approval, labeling, packaging, storage, record‑keeping, promotion, advertising, distribution, marketing and export and import of products such as those we are developing. A new drug must be approved by the FDA through the new drug application, or NDA, process and a new biologic must be approved by the FDA through the biologics license application, or BLA, process before it may be legally marketed in the U.S. United States Drug Development Process In the U.S., the FDA regulates drugs under the federal Food, Drug, and Cosmetic Act, or FDCA, and in the case of biologics, also under the Public Health Service Act, or PHSA, and their implementing regulations. We, along with third-party contractors, will be required to navigate the various preclinical, clinical and commercial approval requirements of the governing regulatory agencies of the countries in which we wish to conduct studies or seek approval or licensure of our product candidates. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources. The following steps are usually required by the FDA before a drug or biologic may be marketed in the U.S.: • • • • • • • • completion of preclinical laboratory tests, animal studies and formulation studies in accordance with GLP requirements and other applicable regulations; submission to the FDA of an Investigational New Drug Application, or IND, which must become effective before human clinical trials may begin; approval by an independent Institutional Review Board, or IRB, or Ethics Committee associated with each clinical site before patients can be enrolled into each trial at that particular clinical site; performance of adequate and well-controlled human clinical trials in accordance with Good Clinical Practices, or GCP, requirements to establish the safety and efficacy of the proposed drug, or safety, purity and potency of the proposed biologic, for its intended use; submission to the FDA of an NDA or BLA after substantial information is available from pivotal clinical trials; a determination by the FDA within 60 days of its receipt of an NDA or BLA whether to file the application for review; potential review of the product application by an FDA advisory committee, where appropriate and if applicable; satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the drug is produced to assess compliance with cGMP requirements to assure that the facilities, methods and controls are adequate to preserve the drug or biologic’s identity, strength, quality and purity, and audits of selected clinical trial sites to ensure compliance with GCP; and FDA review and approval of the NDA or BLA. Preclinical studies usually include laboratory evaluation of product chemistry, toxicity and formulation, as well as animal studies to assess potential safety and efficacy. Prior to beginning the first clinical trial with a product candidate in the U.S., a Sponsor must submit an IND to the FDA, which is a request for authorization from the FDA to administer an investigational new drug product to humans. The U.S. IND submission contains the general investigational plan, the clinical protocol, protocols and results from preclinical studies assessing the toxicology, pharmacokinetics, pharmacology and pharmacodynamic characteristics of the product, chemistry, manufacturing and controls, or CMC, information, and any available human data or literature to support the use of the 36 investigational product. The FDA will review the IND, and if the information is adequate, the IND goes into effect and human clinical trials may begin. The IND automatically goes into effect 30 days after receipt by the FDA, unless the FDA requires additional information which may result in a clinical hold if the data are insufficient. In such a case, the IND Sponsor and the FDA must resolve any outstanding concerns before the clinical study can begin. The FDA may also impose clinical holds on any drug or biological product candidate at any time before or during clinical trials due to safety concerns or non-compliance. If the FDA imposes a clinical hold, one or more trials may not recommence or continue without FDA authorization associated with agreed terms or changes agreed between the FDA and Sponsor. In addition to the submission of an IND to the FDA, supervision of certain human gene transfer trials may also require evaluation and assessment by an institutional biosafety committee, or IBC, a local institutional committee that reviews and oversees research utilizing recombinant or synthetic nucleic acid molecules at that institution. The IBC assesses the safety of the research and identifies any potential risk to the public health or the environment, and such assessment may result in some delay before initiation of a clinical trial. Clinical trials involve the administration of a product candidate to healthy volunteers or patients under the supervision of qualified investigators, generally physicians not employed by or under the study Sponsor’s control. Clinical trials are conducted under protocols detailing, among other things, the objectives of the clinical study, dosing procedures, patient selection and exclusion criteria, and the parameters to be used to monitor patient safety, including stopping rules that assure a clinical study will be stopped if certain adverse events should occur. Each protocol and any amendments to the protocol must be submitted to the FDA as part of the IND. Clinical trials must be conducted and monitored in accordance with the FDA’s regulations including GCP requirements, including the requirement that all research patients provide informed consent. Further, each clinical study must be reviewed and approved by an independent IRB at or servicing each institution at which the clinical study will be conducted. The FDA, the IRBs, or the Sponsor may suspend a clinical trial at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk or if a trial is unlikely to meet its stated objectives. In addition, some clinical trials are overseen by an independent group of qualified experts organized by the Sponsor, known as a data safety monitoring board or committee. Depending on its charter, this group may determine whether a trial may move forward at designated check points based on access to certain data from the trial. There are also requirements governing the reporting of ongoing preclinical studies and clinical trials and clinical study results to public registries. Human clinical trials are typically conducted in three sequential phases that may overlap or be combined: • • • Phase 1: The product candidate is initially administered to healthy human subjects and tested for safety, dosage tolerance, absorption, metabolism, distribution and excretion. In the case of some products for severe or life-threatening diseases, such as cancer, 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 product candidate is administered to 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 the appropriate dosage for further clinical trials. Phase 3: The product candidate is administered to an expanded patient population at geographically dispersed clinical study sites. These clinical trials are intended to establish the safety and efficacy of the product and the overall risk benefit ratio of the product candidate and provide, if appropriate, an adequate basis for product labeling and commercial use of the product. Post-approval trials, sometimes referred to as Phase 4 studies, may be conducted after initial marketing approval. These trials are used to gain additional experience from the treatment of patients in the intended therapeutic indication. In certain instances, the FDA may mandate the performance of Phase 4 clinical trials as a condition of approval of an NDA or BLA. During the development of a new drug or biologic, Sponsors are given opportunities to meet with the FDA at certain points. These meetings may be prior to submission of an IND, at the end of Phase 2, and before an NDA or BLA is submitted, or at other times important in product candidate development. These meetings can provide an opportunity for the Sponsor to share information about the clinical, preclinical or CMC data gathered to date, for the FDA to provide advice, and for the Sponsor and the FDA to reach agreement on the next phase of development. Sponsors typically use the meetings at the end of the Phase 2 trial to discuss Phase 2 clinical results and present plans for the pivotal Phase 3 clinical trial that they believe will support approval of the new drug or biologic. 37 Concurrent with clinical trials, Sponsors usually complete additional animal studies and must also develop additional information about the chemistry and physical characteristics of the drug and finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, the manufacturer must develop methods for testing the identity, strength, quality and purity of the final drug. In addition, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life. While the IND is active and before approval, progress reports summarizing the results of the clinical trials and nonclinical studies performed since the last progress report, among other information, must be submitted at least annually to the FDA, and written IND safety reports must be submitted to the FDA and investigators for serious and unexpected suspected adverse events, findings from other studies suggesting a significant risk to humans exposed to the same or similar drugs, findings from animal or in vitro testing suggesting a significant risk to humans, and any clinically important increased incidence of a serious suspected adverse reaction compared to that listed in the protocol or investigator brochure. There are also requirements governing the reporting of ongoing clinical trials and completed trial results to public registries. Sponsors of certain clinical trials of FDA‑regulated products are required to register and disclose specified clinical trial information, which is publicly available at www.clinicaltrials.gov. Information related to the product, patient population, phase of investigation, trial 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. United States Review and Approval Process The results of product development, preclinical and other preclinical studies and clinical trials, along with descriptions of the manufacturing process, analytical tests conducted on the chemistry of the drug, proposed labeling and other relevant information are submitted to the FDA as part of an NDA or BLA requesting approval to market the product. The NDA or BLA must include all relevant data available from pertinent preclinical studies and clinical trials, including negative or ambiguous results as well as positive findings, together with detailed information relating to the product’s CMC and proposed labeling, among other things. Data can come from company-sponsored clinical studies intended to test the safety and effectiveness of the product, or from several alternative sources, including studies initiated and sponsored by investigators. The submission of an NDA or BLA is subject to the payment of user fees; a waiver of such fees may be obtained under certain limited circumstances (eg., indication for a product with orphan drug designation). Within 60 days following submission of the application, the FDA reviews all NDAs and BLAs submitted to ensure that they are sufficiently complete for substantive review before it accepts them for filing. The FDA may request additional information rather than accept an NDA or BLA for filing. In this event, the NDA or BLA must be resubmitted with the additional information. The resubmitted application also is subject to review before the FDA accepts it for filing. Once the submission is accepted for filing, the FDA will determine the type of review (standard or priority) and the FDA begins an in‑depth substantive review. The FDA’s goal is to review standard applications within ten months after the filing date, or, if the application qualifies for priority review, six months after the FDA accepts the application for filing. In both standard and priority reviews, the review process may also be extended by FDA requests for additional information or clarification. The FDA reviews an NDA to determine, among other things, whether a product is safe and effective for its intended use and whether its manufacturing is cGMP‑compliant to assure and preserve the product’s identity, strength, quality, and purity. The FDA reviews a BLA to determine, among other things whether the product is safe, pure and potent and the facility in which it is manufactured, processed, packed or held meets standards designed to assure the product’s continued safety, purity and potency. The FDA may refer the NDA or BLA to an advisory committee so that independent advice can be provided to contribute to the FDA’s decision-making and lends credibility to the review process. The FDA is not bound by the recommendation of an advisory committee, but it generally follows such recommendations. Before approving an NDA or BLA, the FDA will inspect the facility or facilities where the product is manufactured. The FDA will not approve an application unless it determines that the manufacturing processes and 38 facilities follow cGMP requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving an NDA or BLA, the FDA will typically inspect one or more clinical sites to assure compliance with GCP. If the FDA determines that the application, manufacturing process or manufacturing facilities are not acceptable, it will outline the deficiencies in the submission and often will request additional testing or information. Notwithstanding the submission of any requested additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval. After the FDA evaluates an NDA or BLA and conducts inspections of manufacturing facilities where the investigational product and/or its drug substance will be produced, it will issue an Approval Letter or a Complete Response Letter, or CRL. An Approval Letter authorizes commercial marketing of the drug and is accompanied with the approved U.S. Prescribing Information, or USPI. A CRL indicates that the review cycle of the NDA or BLA is complete and the application will not be approved with the information provided by the Sponsor. A CRL usually describes the specific deficiencies in the NDA or BLA identified by the FDA and may require additional clinical data, such as an additional clinical trial or other significant and time‑consuming requirements related to clinical trials, nonclinical studies, or manufacturing. If a CRL is issued, the Sponsor must resubmit the NDA or BLA, addressing all of the deficiencies identified in the CRL Since the re-submission of the NDA and BLA may address all deficiencies, there is no guarantee that the FDA would approve the NDA or BLA as the circumstances may have changed. If a product receives FDA approval for marketing authorization, the approval may be significantly limited to a specific disease subset, dosages, or use may otherwise be limited, which could restrict the commercial value of the product. In addition, the FDA may require a sponsor to require post- marketing information including additional information from certain trials, perform Phase 4 clinical trials designed to further assess a products safety and effectiveness after NDA or BLA approval, may require testing and surveillance programs to monitor the safety of approved products which have been commercialized, additional CMC information or preclinical studies. The FDA may also place other conditions on approval including the requirement for a Risk Evaluation and Mitigation Strategy, or REMS, to assure the safe use of the drug. If the FDA concludes a REMS is needed, the Sponsor of the NDA or BLA must submit a proposed REMS program. The FDA will not approve the NDA without an approved REMS program, if required. A REMS could include medication guides, physician communication plans or elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. Any of these limitations on approval or marketing could restrict the commercial promotion, distribution, prescription or dispensing of products. Marketing approval may be withdrawn for non‑compliance with regulatory requirements or if problems occur following initial marketing. The FDA Safety and Innovation Act, or FDASIA, made permanent the Pediatric Research Equity Act, or PREA, which requires a sponsor to conduct pediatric clinical trials for most drugs and biologics, for a new active ingredient, new indication, new dosage form, new dosing regimen or new route of administration. Under PREA, original NDAs, BLAs and supplements thereto must contain a pediatric assessment unless the Sponsor has received a deferral or waiver. The required assessment must evaluate the safety and effectiveness of the product for the claimed indications in all relevant pediatric subpopulations and support dosing and administration for each pediatric subpopulation for which the product is safe and effective. The Sponsor or FDA may request a deferral of pediatric clinical trials for some or all of the pediatric subpopulations. A deferral may be granted for several reasons, including a finding that the drug or biologic is ready for approval for use in adults before pediatric clinical trials are complete or that additional safety or effectiveness data needs to be collected before the pediatric clinical trials begin. The FDA must send a noncompliance letter to any sponsor that fails to submit the required assessment, keep a deferral current or fails to submit a request for approval of a pediatric formulation. Orphan Drug Designation Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic intended to treat a rare disease or condition, which is a disease or condition that affects fewer than 200,000 individuals in the U.S. or, if it affects more than 200,000 individuals in the U.S., there is no reasonable expectation that the cost of developing and making a drug or biologic product available in the U.S. for this type of disease or condition will be recovered from sales of the product. Orphan designation must be requested before submitting an NDA or BLA. After the FDA grants orphan designation, the identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. Orphan designation does not convey any advantage in or shorten the duration of the regulatory review and approval process. 39 If a product that has orphan designation subsequently receives the first FDA approval for the disease or condition for which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any other applications to market the same drug or biological product for the same indication for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan exclusivity or inability to manufacture the product in sufficient quantities. The designation of such drug or biologic also entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and user‑fee waivers. However, competitors, may receive approval of different products for the indication for which the orphan product has exclusivity or obtain approval for the same product but for a different indication for which the orphan product has exclusivity. A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan designation. In addition, exclusive marketing rights in the U.S. may be lost if the FDA later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition. Expedited Development and Review Programs The FDA offers several expedited development and review programs for qualifying product candidates. For example, the FDA has a Fast Track program that is intended to expedite or facilitate the process for reviewing new drug products that meet certain criteria. Specifically, new drugs or biologics are eligible for Fast Track designation if they are intended for the treatment of a serious or life-threatening disease or condition and which demonstrate the potential to address an unmet medical need for the disease or condition. An unmet medical need is a condition whose treatment or diagnosis is not addressed adequately by available therapy. The Sponsor of a Fast Track product candidate has opportunities for more frequent meetings with the FDA review team during product development and, once an NDA or BLA is submitted, the product may be eligible for priority review. Fast Track designation applies to the combination of the product candidate and the specific indication for which it is being studied. With regard to a Fast Track product candidate, the FDA may consider for review sections of the NDA or BLA on a rolling basis before the complete application is submitted, if the Sponsor provides a schedule for the submission of the sections of the NDA or BLA, the FDA agrees to accept sections of the NDA or BLA and determines that the schedule is acceptable, and the Sponsor pays any required user fees upon submission of the first section of the NDA or BLA. A product candidate intended to treat a serious or life-threatening disease or condition may also be eligible for Breakthrough Therapy designation (BTD) to expedite its development and review. A product candidate can receive BTD if preliminary clinical evidence indicates that the product candidate, alone or in combination with one or more other drugs or biologics, may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. The designation includes all the Fast Track program features, as well as more intensive FDA interaction and guidance beginning as early as Phase 1 and an organizational commitment to expedite the development and review of the product candidate, including involvement of senior managers. Any product candidate submitted to the FDA for approval, including a product with a Fast Track designation or Breakthrough Therapy designation, may also be eligible for other types of FDA programs intended to expedite development and review, such as priority review and Accelerated Approval. A BLA or NDA for a product candidate is eligible for priority review if the product candidate has the potential to provide a significant improvement in the treatment, diagnosis or prevention of a serious disease or condition compared to marketed products. A serious disease or condition is a disease or condition associated with morbidity that has a substantial impact on day-to-day functioning. Short-lived and self-limiting morbidity will usually not be sufficient, but the morbidity need not be irreversible if it is persistent or recurrent. The FDA will attempt to direct additional resources to the evaluation of a BLA or NDA designated for priority review in an effort to facilitate the review. The FDA endeavors to review applications with priority review designations within six months of the filing date as compared to ten months for review of original BLAs and new molecular entity NDAs under its standard review goals. 40 In addition, a product candidate may be eligible for Accelerated Approval. Drugs and biologics intended to treat serious or life-threatening diseases or conditions may be eligible for Accelerated Approval upon a determination that the product candidate has an effect on a surrogate endpoint, is a marker such as a laboratory measurement, radiographic image, physical sign, or other measure, that is thought to predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments. As a condition of approval, the FDA may require that a Sponsor of a drug receiving Accelerated Approval perform adequate and well-controlled postmarketing confirmation clinical trials. As a condition of Accelerated Approval, the FDA will generally require the Sponsor to perform adequate and well-controlled post-marketing clinical studies to verify and describe the anticipated effect on irreversible morbidity or mortality or other clinical benefit. Products approval using the Accelerated Approval pathway may be subject to expedited withdrawal procedures if the Sponsor fails to conduct the required post- marketing studies or if such studies fail to verify the predicted clinical benefit. In addition, the FDA currently requires as a condition for Accelerated Approval preapproval of promotional materials, which could adversely impact the commercial launch of the product. In 2017, the FDA established the regenerative medicine advanced therapy, or RMAT, designation as part of its implementation of the 21st Century Cures Act. The RMAT designation program is intended to fulfill the 21st Century Cures Act requirement that the FDA facilitate an efficient development program for, and expedite review of, any drug or biologic. Regenerative medicine therapies to treat, modify, reverse, or cure serious conditions are eligible for FDA’s expedited programs, including fast track designation, breakthrough therapy designation, RMAT designation, Accelerated Approval, and priority review designation, if they meet the criteria for such programs. that meets the following criteria: (i) the drug or biologic qualifies as a RMAT, which is defined as a cell therapy, therapeutic tissue engineering product, human cell and tissue product, or any combination product using such therapies or products, with limited exceptions; (ii) the drug or biologic is intended to treat, modify, reverse, or cure a serious or life-threatening disease or condition; and (iii) preliminary clinical evidence indicates that the drug or biologic has the potential to address unmet medical needs for such a disease or condition. Fast Track designation, Breakthrough Therapy designation, RMAT designation, priority review and Accelerated Approval do not change the standards for approval but may expedite the development or approval process. Even if a product candidate qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the conditions for qualification or decide that the time for FDA review or approval will not be shortened. Rare Pediatric Disease Priority Review Voucher Program In 2012, the U.S. Congress authorized the FDA to award priority review vouchers to Sponsors of certain rare pediatric disease product applications. This program is designed to encourage development of new drug and biological products for prevention and treatment of certain rare pediatric diseases. Specifically, under this program, a sponsor who receives an approval for a drug or biologic for a “rare pediatric disease” may qualify for a voucher that can be redeemed to receive priority review of a subsequent marketing application for a different product. The Sponsor of a rare pediatric disease drug product receiving a priority review voucher may transfer (including by sale) the voucher to another sponsor. The voucher may be further transferred any number of times before the voucher is used, as long as the Sponsor making the transfer has not yet submitted the application. The FDA may also revoke any priority review voucher if the rare pediatric disease drug for which the voucher was awarded is not marketed in the U.S. within one year following the date of approval. For purposes of this program, a “rare pediatric disease” is a (a) serious or life-threatening disease in which the serious or life-threatening manifestations primarily affect individuals aged from birth to 18 years, including age groups often called neonates, infants, children, and adolescents; and (b) rare diseases or conditions within the meaning of the Orphan Drug Act. On December 27, 2020, the Rare Pediatric Disease Priority Review Voucher Program was extended. Under the current statutory sunset provisions, after September 30, 2024, FDA may only award a voucher for an approved rare pediatric disease product application if the Sponsor has rare pediatric disease designation for the drug, and that designation was granted by September 30, 2024. After September 30, 2026, FDA may not award any Rare Pediatric Disease Priority Review Voucher. 41 Post‑approval requirements Once an approval of marketing authorization is granted, the FDA may withdraw the approval if compliance with regulatory standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product may result in restrictions on the product or even complete withdrawal of the product from the market. After approval, some types of changes to the approved product, such as adding new indications, certain manufacturing changes and additional labeling claims, are subject to further FDA review and approval. Drug and biologics manufacturers and other entities involved in the manufacture and distribution of approved drugs and biologics 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 regulations and other laws and regulations. Changes to the manufacturing process are strictly regulated, and, depending on the significance of the change, may require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting requirements upon us and any third-party manufacturers that we may decide to use. Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain compliance with cGMP and other aspects of regulatory compliance. Any drug products we or our partners manufacture or distribute pursuant to FDA marketing authorization approvals will be subject to continuing regulation by the FDA, irrespective of the country of manufacture, including, among other things, recordkeeping requirements, reporting of adverse experiences with the drug, providing the FDA with updated safety and efficacy information, drug sampling and distribution requirements, complying with certain electronic records and signature requirements, and complying with FDA promotion and advertising requirements. The FDA strictly regulates labeling, advertising, promotion and other types of information on products that are placed on the market and imposes requirements and restrictions on drug and biologics manufacturers, such as those related to direct to consumer advertising, the prohibition on promoting products for uses or in patient populations that are not described in the product’s approved labeling (known as “off-label use”), industry sponsored scientific and educational activities, and promotional activities involving the internet. A company can make only those claims relating to safety and efficacy, purity and potency that are approved by the FDA and consistent with the provisions of the approved label. Failure to comply with these requirements can result in, among other things, adverse publicity, warning letters, corrective advertising, and potential civil and criminal penalties. Physicians may prescribe legally available products for uses that are not described in the product’s labeling and that differ from those tested by us and approved by the FDA. Such off-label uses are common across medical specialties. Physicians may believe that such off-label uses are the best treatment for many patients in varied circumstances. The FDA does not regulate the behavior of physicians in their choice of treatments. The FDA does, however, restrict manufacturer’s communications about off-label use of their products. Discovery of previously unknown problems or the failure to comply with the applicable regulatory requirements may result in restrictions on the marketing of a product or withdrawal of the product from the market as well as possible civil or criminal sanctions. Failure to comply with the applicable U.S. requirements at any time during the product development process, approval process or after approval, may subject an applicant or manufacturer to administrative or judicial civil or criminal sanctions and adverse publicity. FDA sanctions could include refusal to approve pending applications or supplements to approved applications, withdrawal of an approval, clinical hold, warning or untitled letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, mandated corrective advertising or communications with doctors, debarment, restitution, disgorgement of profits, or civil or criminal penalties. 42 Drug Product Marketing Exclusivity Market exclusivity provisions authorized under the FDCA can delay the submission or the approval of certain marketing applications. For example, the FDCA provides a five-year period of non-patent marketing exclusivity within the U.S. to the first applicant to obtain approval of an NDA for a new chemical entity. A drug is a new chemical entity if the FDA has not previously approved any other new drug containing the same active moiety, which is the molecule or ion responsible for the action of the drug substance. During the exclusivity period, the FDA may not approve or even accept for review an abbreviated new drug application, or ANDA, or an NDA submitted under Section 505(b)(2), or 505(b)(2) NDA, submitted by another company for another drug based on the same active moiety, regardless of whether the drug is intended for the same indication as the original innovative drug or for another indication, where the applicant does not own or have a legal right of reference to all the data required for approval. However, an application may be submitted after four years if it contains a certification of patent invalidity or non-infringement to one of the patents listed with the FDA by the innovator NDA holder. The FDCA alternatively provides three years of marketing exclusivity for an NDA, or supplement to an existing NDA if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application, for example new indications, dosages or strengths of an existing drug. This three-year exclusivity covers only the modification for which the drug received approval on the basis of the new clinical investigations and does not prohibit the FDA from approving ANDAs or 505(b)(2) NDAs for drugs containing the active agent for the original indication or condition of use. Five-year and three-year exclusivity will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA would be required to conduct or obtain a right of reference to any preclinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness. Pediatric exclusivity is another type of marketing exclusivity available in the U.S. Pediatric exclusivity provides for an additional six months of marketing exclusivity attached to another period of exclusivity if a sponsor conducts clinical trials in children in response to a written request from the FDA. The issuance of a written request does not require the Sponsor to undertake the described clinical trials. In addition, orphan drug exclusivity, as described above, may offer a seven-year period of marketing exclusivity, except in certain circumstances. Biosimilars and Exclusivity The Affordable Care Act includes a subtitle called the Biologics Price Competition and Innovation Act of 2009, or BPCIA, which created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an FDA licensed reference biological product. The FDA has issued several guidance documents outlining an approach to review and approval of biosimilars. Biosimilarity, which requires that there be no clinically meaningful differences between the biological product and the reference product in terms of safety, purity, and potency, can be shown through analytical studies, animal studies, and a clinical study or studies. Interchangeability requires that a product is biosimilar to the reference product and the product must demonstrate that it can be expected to produce the same clinical results as the reference product in any given patient and, for products that are administered multiple times to an individual, the biologic and the reference biologic may be alternated or switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biologic. However, complexities associated with the larger, and often more complex, structures of biological products, as well as the processes by which such products are manufactured, pose significant hurdles to implementation of the abbreviated approval pathway that are still being addressed by the FDA. Under the BPCIA, an application for a biosimilar product may not be submitted to the FDA until four years following the date that the reference product was first licensed by the FDA. In addition, 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 interchangeable products. At this juncture, it is unclear whether products deemed “interchangeable” by the FDA will, in fact, be readily substituted by pharmacies, which are governed by state pharmacy law. 43 A biological product can also obtain pediatric market exclusivity in the U.S. Pediatric exclusivity, if granted, adds six months to existing exclusivity periods and patent terms. This six-month exclusivity, which runs from the end of other exclusivity protection or patent term, may be granted based on the voluntary completion of a pediatric study in accordance with an FDA-issued “Written Request” for such a study. FDA Regulation of Companion Diagnostics Our product candidates may require use of an in vitro diagnostic to identify appropriate patient populations. These diagnostics, often referred to as companion diagnostics, are regulated as medical devices. In the U.S., the FDCA and its implementing regulations, and other federal and state statutes and regulations govern, among other things, medical device design and development, preclinical and clinical testing, premarket clearance or approval, registration and listing, manufacturing, labeling, storage, advertising and promotion, sales and distribution, export and import, and post-market surveillance. Unless an exemption applies, companion diagnostic tests require marketing clearance or approval from the FDA prior to commercial distribution. The two primary types of FDA marketing authorization applicable to a medical device are premarket notification, also called 510(k) clearance, and premarket approval, or PMA, approval. If use of companion diagnostic is essential to safe and effective use of a drug or biologic product, then the FDA generally will require approval or clearance of the diagnostic contemporaneously with the approval of the therapeutic product. On August 6, 2014, the FDA issued a final guidance document addressing the development and approval process for “In Vitro Companion Diagnostic Devices.” According to the guidance, for novel candidates such as our product candidates, a companion diagnostic device and its corresponding drug or biologic candidate should be approved or cleared contemporaneously by FDA for the use indicated in the therapeutic product labeling. The guidance also explains that a companion diagnostic device used to make treatment decisions in clinical trials of a drug generally will be considered an investigational device, unless it is employed for an intended use for which the device is already approved or cleared. If used to make critical treatment decisions, such as patient selection, the diagnostic device generally will be considered a significant risk device under the FDA’s Investigational Device Exemption, or IDE, regulations. Thus, the Sponsor of the diagnostic device will be required to comply with the IDE regulations. According to the guidance, if a diagnostic device and a drug are to be studied together to support their respective approvals, both products can be studied in the same investigational study, if the study meets both the requirements of the IDE regulations and the IND regulations. The guidance provides that depending on the details of the study plan and subjects, a sponsor may seek to submit an IND alone, or both an IND and an IDE. In July 2016, the FDA issued a draft guidance document intended to further assist sponsors of therapeutic products and sponsors of in vitro companion diagnostic devices on issues related to co-development of these products. The FDA generally requires companion diagnostics intended to select the patients who will respond to cancer treatment to obtain approval of a PMA for that diagnostic contemporaneously with approval of the therapeutic. The review of these in vitro companion diagnostics in conjunction with the review of therapeutic candidates such as those we are developing involves coordination of review by the FDA’s Center for Drug Evaluation and Research and by the FDA’s Center for Devices and Radiological Health. The PMA process, including the gathering of clinical and preclinical data and the submission to and review by the FDA, can take several years or longer. It involves a rigorous premarket review during which the applicant must prepare and provide the FDA with reasonable assurance of the device’s safety and effectiveness and information about the device and its components regarding, among other things, device design, manufacturing, and labeling. PMA applications are also subject to an application fee. In addition, PMAs for certain devices must generally include the results from extensive preclinical and adequate and well-controlled clinical trials to establish the safety and effectiveness of the device for each indication for which FDA approval is sought. In particular, for a diagnostic, the applicant must demonstrate that the diagnostic produces reproducible results when the same sample is tested multiple times by multiple users at multiple laboratories. In addition, as part of the PMA review, the FDA will typically inspect the manufacturer’s facilities for compliance with the Quality System Regulation, or QSR, which imposes elaborate testing, control, documentation and other quality assurance requirements. If the FDA evaluations of both the PMA application and the manufacturing facilities are favorable, the FDA will either issue an approval letter or an approvable letter, which usually contains several conditions that must be met in order to secure the final approval of the PMA, such as changes in labeling, or specific additional information, such as submission of final labeling, in order to secure final approval of the PMA. If the FDA concludes that the applicable criteria have been met, the FDA will issue a PMA for the approved indications, which can be more 44 limited than those originally sought by the applicant. The PMA can include post-approval conditions that the FDA believes necessary to ensure the safety and effectiveness of the device, including, among other things, restrictions on labeling, promotion, sale and distribution. If the FDA’s evaluation of the PMA or manufacturing facilities is not favorable, the FDA will deny approval of the PMA or issue a not approvable letter. A not approvable letter will outline the deficiencies in the application and, where practical, will identify what is necessary to make the PMA approvable. The FDA may also determine that additional clinical trials are necessary, in which case the PMA approval may be delayed for several months or years while the trials are conducted and then the data submitted in an amendment to the PMA. Once granted, PMA approval may be withdrawn by the FDA if compliance with post approval requirements, conditions of approval or other regulatory standards is not maintained, or problems are identified following initial marketing. PMA approval is not guaranteed, and the FDA may ultimately respond to a PMA submission with a not approvable determination based on deficiencies in the application and require additional clinical trial or other data that may be expensive and time-consuming to generate and that can substantially delay approval. After a device is placed on the market, it remains subject to significant regulatory requirements. Medical devices may be marketed only for the uses and indications for which they are cleared or approved. Device manufacturers must also establish registration and device listings with the FDA. A medical device manufacturer’s manufacturing processes and those of its suppliers are required to comply with the applicable portions of the QSR, which cover the methods and documentation of the design, testing, production, processes, controls, quality assurance, labeling, packaging, and shipping of medical devices. Domestic facility records and manufacturing processes are subject to periodic unscheduled inspections by the FDA. The FDA also may inspect foreign facilities that export products to the U.S. Approval Process Outside of the United States In addition to regulations in the U.S., we will be subject to a variety of regulations in other jurisdictions governing, among other things, clinical trials, marketing authorization, post-marketing requirements and any commercial sales and distribution of our product candidates. Because biologically sourced raw materials are subject to unique contamination risks, their use may be restricted in some countries. In addition, ethical, social, and legal concerns about gene-editing technology, gene therapy, genetic testing and genetic research could result in additional regulations restricting or prohibiting the processes we may want to use. Whether or not we obtain FDA approval for a product candidate, we must obtain the requisite approvals from regulatory authorities in foreign countries prior to the commencement of clinical trials or marketing of the product candidates in those countries. The requirements and process governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country. Failure to comply with applicable foreign regulatory requirements, may be subject to, among other things, fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions, and criminal prosecution. Regulations Governing Marketing Authorization of Medicinal Products in the European Union Preclinical studies and clinical trials Similarly to the U.S., the various phases of preclinical and clinical research in the European Union, or EU, are subject to significant regulatory controls. Preclinical studies are performed to demonstrate the health or environmental safety of new chemical or biological substances. Preclinical studies must be conducted in compliance with the principles of GLP as set forth in EU Directive 2004/10/EC. In particular, preclinical studies, both in vitro and in vivo, must be planned, performed, monitored, recorded, reported and archived in accordance with the GLP principles, which define a set of rules and criteria for a quality system for the organizational process and the conditions for preclinical studies. The regulatory landscape related to clinical trials in the EU has been subject to recent changes. The EU Clinical Trials Regulation, or CTR, which was adopted in April 2014 and repeals the EU Clinical Trials Directive, became applicable on January 31, 2022. The CTR foresees a three-year transition period. The extent to which ongoing and new clinical trials will be governed by the CTR varies. For clinical trials whose CTA was made under the Clinical Trials Directive before January 31, 2022, the Clinical Trials Directive will continue to apply on a 45 transitional basis for three years. Additionally, Sponsors may still choose to submit a CTA under either the Clinical Trials Directive or the CTR until January 31, 2023 and, if authorized, those will be governed by the Clinical Trials Directive until January 31, 2025. By that date, all ongoing trials will become subject to the provisions of the CTR. Unlike directives, the CTR is directly applicable in all EU member states without the need for member states to further implement it into national law. The CTR notably harmonizes the assessment and supervision processes for clinical trials throughout the EU via a Clinical Trials Information System, which contains a centralized EU portal and database. While the Clinical Trials Directive required a separate clinical trial application, or CTA, to be submitted in each member state, to both the competent national health authority and an independent ethics committee, much like the FDA and IRB respectively, the CTR introduces a centralized process and only requires the submission of a single application to all member states concerned. The CTR allows sponsors to make a single submission to both the competent authority and an ethics committee in each member state, leading to a single decision per member state. The CTA must include, among other things, a copy of the trial protocol and an investigational medicinal product dossier, or IMPD, containing information about the manufacture and quality of the medicinal product under investigation. The assessment procedure of the CTA has been harmonized as well, including a joint assessment by all member states concerned, and a separate assessment by each member state with respect to specific requirements related to its own territory, including ethics rules. Each member state’s decision is communicated to the Sponsor via the centralized EU portal. Once the CTA is approved, clinical study development may proceed. Medicines used in clinical trials must be manufactured in accordance with GMP. Other national and EU-wide regulatory requirements may also apply. Marketing Authorization In the EU, to obtain regulatory approval of an investigational chemical or biological product under EU regulatory systems, a marketing authorization application, or MAA, must be submitted. Medicinal product candidates can only be placed on the market after obtaining a marketing authorization, or MA. The process for doing this depends, among other things, on the nature of the medicinal product. “Centralized MAs” are issued by the European Commission through the centralized procedure, based on the opinion of the Committee for Medical Products for Human Use, or CHMP, of the European Medicines Agency, or EMA, and are valid throughout the EU. The centralized procedure is compulsory for certain types of medicinal medicines, such as: (i) medicinal products derived from biotechnology processes, such as genetic engineering, (ii) medicinal products containing a new active substance indicated for the treatment of certain diseases, such as HIV/AIDS, cancer, diabetes, neurodegenerative diseases, autoimmune and other immune dysfunctions and viral diseases, (iii) designated orphan medicines, and (iv) Advanced Therapy Medicinal Products, or ATMPs, such as gene therapy, somatic cell therapy or tissue-engineered medicines. The centralized procedure may at the request of the applicant also be used in certain other cases. It is very likely that the centralized procedure would apply to the products we are developing. The Committee for Advanced Therapies, or CAT, is responsible in conjunction with the CHMP for the evaluation of ATMPs. The CAT is primarily responsible for the scientific evaluation of ATMPs and prepares a draft opinion on the quality, safety and efficacy of each ATMP for which a MAA is submitted. The CAT’s opinion is then taken into account by the CHMP when giving its final recommendation regarding the authorization of a product in view of the balance of benefits and risks identified. Although the CAT’s draft opinion is submitted to the CHMP for final approval, the CHMP may depart from the draft opinion, if it provides detailed scientific justification. The CHMP and CAT are also responsible for providing guidelines on ATMPs and have published numerous guidelines, including specific guidelines on gene therapies and cell therapies. These guidelines provide additional guidance on the factors that the EMA will consider in relation to the development and evaluation of ATMPs and include, among other things, the preclinical studies required to characterize ATMPs; the manufacturing and control information that should be submitted in a marketing authorization application; and post- approval measures required to monitor patients and evaluate the long-term efficacy and potential adverse reactions of ATMPs. Under the centralized procedure and in exceptional cases, the CHMP might perform an accelerated review of a MA in no more than 150 days (not including clock stops). Innovative products that target an unmet medical need 46 and are expected to be of major public health interest may be eligible for a number of expedited development and review programs, such as the PRIME scheme, which provides incentives similar to the breakthrough therapy designation in the U.S. In March 2016, the EMA launched an initiative, the Priority Medicines, or PRIME, scheme, a voluntary scheme aimed at enhancing the EMA’s support for the development of medicines that target unmet medical needs. It is based on increased interaction and early dialogue with companies developing promising medicines, to optimize their product development plans and speed up their evaluation to help them reach patients earlier. Product developers that benefit from PRIME designation can expect to be eligible for accelerated assessment, but this is not guaranteed. Many benefits accrue to sponsors of product candidates with PRIME designation, including but not limited to, early and proactive regulatory dialogue with the EMA, frequent discussions on clinical trial designs and other development program elements, and accelerated MAA assessment once a dossier has been submitted. Importantly, a dedicated contact and rapporteur from the CHMP is appointed early in the PRIME scheme facilitating increased understanding of the product at EMA’s committee level. An initial meeting initiates these relationships and includes a team of multidisciplinary experts at the EMA to provide guidance on the overall development and regulatory strategies. Moreover, in the EU, a “conditional” MA may be granted in cases where all the required safety and efficacy data are not yet available. The conditional MA is subject to conditions to be fulfilled for generating the missing data or ensuring increased safety measures. It is valid for one year and must be renewed annually until fulfillment of all the conditions. Once the pending studies are provided, it can become a “standard” MA. However, if the conditions are not fulfilled within the timeframe set by the EMA, the MA ceases to be renewed. Furthermore, MA may also be granted “under exceptional circumstances” when the applicant can show that it is unable to provide comprehensive data on the efficacy and safety under normal conditions of use even after the product has been authorized and subject to specific procedures being introduced. This may arise when the intended indications are very rare and, in the present state of scientific knowledge, it is not possible to provide comprehensive information, or when generating data may be contrary to generally accepted ethical principles. This MA is close to the conditional MA as it is reserved to medicinal products to be approved for severe diseases or unmet medical needs and the applicant does not hold the complete data set legally required for the grant of a MA. However, unlike the conditional MA, the applicant does not have to provide the missing data and will never have to. Although the MA “under exceptional circumstances” is granted definitively, the risk-benefit balance of the medicinal product is reviewed annually and the MA is withdrawn in case the risk-benefit ratio is no longer favorable. MAs have an initial duration of five years. After these five years, the authorization may be renewed for an unlimited period on the basis of a reevaluation of the risk-benefit balance. Data and Marketing Exclusivity The EU also provides opportunities for market exclusivity. Upon receiving MA, reference medicinal products generally qualify for eight years of data exclusivity and an additional two years of market exclusivity. If granted, data exclusivity prevents generic or biosimilar applicants from relying on the preclinical and clinical trial data contained in the dossier of the reference product when applying for a generic or biosimilar MA in the EU during a period of eight years from the date on which the reference product was first authorized in the EU. During the additional two‑year period of market exclusivity, a generic/biosimilar MA can be submitted, and the innovator’s data may be referenced, but no generic/biosimilar product can be marketed until 10 years have elapsed from the initial authorization of the reference product in the EU. The overall ten-year market exclusivity period may be extended to a maximum of eleven years if, during the first eight years of those 10 years, the MA holder obtains an authorization for one or more new therapeutic indications which, during the scientific evaluation prior to their authorization, are held to bring a significant clinical benefit in comparison with existing therapies. However, there is no guarantee that a product will be considered by the EU’s regulatory authorities to be a new chemical/biological entity, and products may not qualify for data exclusivity. Orphan Medicinal Products The criteria for designating an “orphan medicinal product” in the EU are similar in principle to those in the U.S. A medicinal product may be designated as orphan if its Sponsor can establish that: (1) the product is intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition; (2) either (a) such condition affects no more than five in 10,000 persons in the EU when the application is made, or (b) the 47 product, without the benefits derived from orphan status, would not generate sufficient return in the EU to justify investment; and (3) there exists no satisfactory method of diagnosis, prevention or treatment of such condition authorized for marketing in the EU, or if such a method exists, the product will be of significant benefit to those affected by the condition. The application for orphan drug designation must be submitted before the application for MA. Orphan drug designation entitles a party to financial incentives such as reduction of fees or fee waivers and access to the centralized procedure. Once authorized, orphan medicinal products are entitled to ten years of market exclusivity for the approved therapeutic indication. During the ten-year market exclusivity period, the competent authorities cannot accept a MAA, or grant a MA, or accept an application to extend a MA, for the same indication, in respect of a similar medicinal product. The applicant will receive a fee reduction for the MAA if the orphan drug designation has been granted, but not if the designation is still pending at the time the MAA is submitted. The period of market exclusivity is extended by two years for orphan medicinal products that have also complied with an agreed pediatric investigation plan, or PIP. No extension to any supplementary protection certificate can be granted on the basis of pediatric studies for orphan indications. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process. The 10‑year market exclusivity may be reduced to six years if, at the end of the fifth year, it is established that the product no longer meets the criteria for orphan designation, for example, if the product is sufficiently profitable not to justify maintenance of market exclusivity, or where the prevalence of the condition has increased above the threshold. In addition, MA may be granted to a similar product for the same indication at any time if (1) the second applicant can establish that its product, although similar, is safer, more effective or otherwise clinically superior; (2) the applicant consents to a second orphan medicinal product application; or (3) the applicant cannot supply enough quantities of the orphan medicinal product. A company may voluntarily remove a product from the orphan register. The aforementioned EU rules are generally applicable in the European Economic Area, or EEA, which consists of the 27 EU member states plus Norway, Liechtenstein and Iceland. Failure to comply with EU and member state laws that apply to the conduct of clinical trials, manufacturing approval, MA of medicinal products and marketing of such products, both before and after grant of the MA, manufacturing of pharmaceutical products, statutory health insurance, bribery and anti-corruption or with other applicable regulatory requirements may result in administrative, civil or criminal penalties. These penalties could include delays or refusal to authorize the conduct of clinical trials, or to grant MA, product withdrawals and recalls, product seizures, suspension, withdrawal or variation of the MA, total or partial suspension of production, distribution, manufacturing or clinical trials, operating restrictions, injunctions, suspension of licenses, fines and criminal penalties. Regulation of Companion Diagnostics in the EU In the EU, in vitro diagnostic medical devices are regulated by Directive 98/79/EC, or IVDD, which regulates the placing on the market, the CE marking, the essential requirements, the conformity assessment procedures, the registration obligations for manufactures and devices as well as the vigilance procedure. In vitro diagnostic medical devices must comply with the requirements provided for in the Directive, and with further requirements implemented at national level (as the case may be). The regulation of companion diagnostics will be subject to further requirements once the in-vitro diagnostic medical devices Regulation No 2017/746, or IVDR, will become applicable on May 26, 2022. However, on October 14, 2021, the European Commission proposed a “progressive” roll-out of the IVDR to prevent disruption in the supply of in vitro diagnostic medical devices. The European Parliament and Council adopted the proposed regulation on December 15, 2021. The IVDR will fully apply on May 26, 2022, but there will be a tiered system extending the grace period for many devices (depending on their risk classification) before they have to be fully compliant with the regulation. The IVDR introduces a new classification system for companion diagnostics which are now specifically defined as diagnostic tests that support the safe and effective use of a specific medicinal product, by identifying patients that are suitable or unsuitable for treatment. Companion diagnostics will have to undergo a conformity 48 assessment by a notified body. Before it can issue a CE certificate, the notified body must seek a scientific opinion from the EMA on the suitability of the companion to the medicinal product concerned if the medicinal product falls exclusively within the scope of the centralized procedure for the authorization of medicines, or the medicinal product is already authorized through the centralized procedure, or a MAA for the medicinal product has been submitted through the centralized procedure. For other substances, the notified body can seek the opinion from a national competent authorities or the EMA. The aforementioned EU rules are generally applicable in the EEA. Brexit and the Regulatory Framework in the United Kingdom The United Kingdom, or UK, left the EU on January 31, 2020, following which existing EU medicinal product legislation continued to apply in the UK during the transition period under the terms of the EU-UK Withdrawal Agreement. The transition period, which ended on December 31, 2020, maintained access to the EU single market and to the global trade deals negotiated by the EU on behalf of its members. The transition period provided time for the UK and EU to negotiate a framework for partnership for the future, which was then crystallized in the Trade and Cooperation Agreement, or TCA, and became effective on the January 1, 2021. The TCA includes specific provisions concerning pharmaceuticals, which include the mutual recognition of GMP inspections of manufacturing facilities for medicinal products and GMP documents issued, but does not foresee wholesale mutual recognition of UK and EU pharmaceutical regulations. EU laws which have been transposed into UK law through secondary legislation continue to be applicable as “retained EU law”. However, new legislation such as the EU CTR will not be applicable. The UK government has passed a new Medicines and Medical Devices Act 2021, which introduces delegated powers in favor of the Secretary of State or an ‘appropriate authority’ to amend or supplement existing regulations in the area of medicinal products and medical devices. This allows new rules to be introduced in the future by way of secondary legislation, which aims to allow flexibility in addressing regulatory gaps and future changes in the fields of human medicines, clinical trials and medical devices. As of January 1, 2021, the Medicines and Healthcare products Regulatory Agency, or MHRA, is the UK’s standalone medicines and medical devices regulator. As a result of the Northern Ireland protocol, different rules will apply in Northern Ireland than in England, Wales, and Scotland, together, Great Britain, or GB; broadly, Northern Ireland will continue to follow the EU regulatory regime, but its national competent authority will remain the MHRA. The MHRA has published a guidance on how various aspects of the UK regulatory regime for medicines will operate in GB and in Northern Ireland following the expiry of the Brexit transition period on December 31, 2020. The guidance includes clinical trials, importing, exporting, and pharmacovigilance and is relevant to any business involved in the research, development, or commercialization of medicines in the UK. The new guidance was given effect via the Human Medicines Regulations (Amendment etc.) (EU Exit) Regulations 2019, or the Exit Regulations. The MHRA has introduced changes to national licensing procedures, including procedures to prioritize access to new medicines that will benefit patients, including a 150-day assessment and a rolling review procedure. All existing EU MAs for centrally authorized products were automatically converted or grandfathered into UK MAs, effective in GB (only), free of charge on January 1, 2021, unless the MA holder chooses to opt-out. In order to use the centralized procedure to obtain a MA that will be valid throughout the EEA, companies must be established in the EEA. Therefore, after Brexit, companies established in the UK can no longer use the EU centralized procedure and instead an EEA entity must hold any centralized MAs. In order to obtain a UK MA to commercialize products in the UK, an applicant must be established in the UK and must follow one of the UK national authorization procedures or one of the remaining post-Brexit international cooperation procedures. The MHRA may rely on a decision taken by the European Commission on the approval of a new (centralized procedure) MA when determining an application for a GB authorization; or use the MHRA’s decentralized or mutual recognition procedures which enable MAs approved in EU member states (or Iceland, Liechtenstein, Norway) to be granted in GB. 49 Other Foreign Regulations Governing Marketing Authorization of Medicinal Products For other countries outside of the EU, such as countries in Eastern Europe, Latin America or Asia, the requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country. In all cases, again, the clinical trials are conducted in accordance with GCP and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki. If we fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things, fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution. Other Healthcare Laws and Compliance Requirements Pharmaceutical companies are subject to additional healthcare regulation and enforcement by the U.S. federal and state governments and by authorities in the foreign jurisdictions in which they conduct their business and may constrain the financial arrangements and relationships through which we research, as well as sell, market and distribute any products for which we obtain marketing authorization. Such laws include, without limitation, state and federal anti-kickback, fraud and abuse, false claims, data privacy and security, and transparency laws and regulations related to drug pricing and payments and other transfers of value made to physicians and other healthcare providers. Violation of these laws or other governmental regulations may result in penalties, including, without limitation, significant civil, criminal and administrative penalties, damages, fines, exclusion from government-funded healthcare programs, such as Medicare and Medicaid or similar programs in other countries or jurisdictions, integrity oversight and reporting obligations to resolve allegations of non-compliance, disgorgement, imprisonment, contractual damages, reputational harm, diminished profits and the curtailment or restructuring of operations. Coverage and Reimbursement Significant uncertainty exists as to the coverage and reimbursement status of any pharmaceutical or biological product for which we obtain regulatory approval. Sales of any product depend, in part, on the extent to which such product will be covered by third-party payors, such as federal, state, and foreign government healthcare programs, commercial insurance and managed healthcare organizations, and the level of reimbursement for such product by third-party payors. Decisions regarding the extent of coverage and amount of reimbursement to be provided are made on a plan-by-plan basis. Further, no uniform policy for coverage and reimbursement exists in the U.S., and coverage and reimbursement can differ significantly from payor to payor. Third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own reimbursement rates, but also have their own methods and approval process apart from Medicare determinations. As a result, the coverage determination process is often a time-consuming and costly process that may require companies to provide scientific and clinical support for the use of a product to each payor separately. For products administered under the supervision of a physician, obtaining coverage and adequate reimbursement may be particularly difficult because of the higher prices often associated with such drugs. Additionally, separate reimbursement for the product itself or the treatment or procedure in which the product is used may not be available, which may impact physician utilization. Lastly, companion diagnostic tests require coverage and reimbursement separate and apart from the coverage and reimbursement for their companion pharmaceutical or biological products. Similar challenges to obtaining coverage and reimbursement, applicable to pharmaceutical or biological products, will apply to companion diagnostics. In addition, the U.S. government, state legislatures and foreign governments have continued implementing cost-containment programs, including price controls, restrictions on coverage and reimbursement and requirements for substitution of generic (or biosimilar) products. Third-party payors are increasingly challenging the prices charged for medical products and services, examining the medical necessity, and reviewing the cost effectiveness of pharmaceutical or biological products, medical devices and medical services, in addition to questioning safety and efficacy. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit sales of any product. Decreases in third-party reimbursement for any product or a decision by a third-party payor not to cover a product could reduce physician usage and patient demand for the product. Healthcare Reform The U.S. and some foreign jurisdictions are considering or have enacted several reform proposals to change the healthcare system. There is significant interest in promoting changes in healthcare systems with the stated goals 50 of containing healthcare costs, improving quality or expanding access. In the U.S., the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by federal and state legislative initiatives, including those designed to limit the pricing, coverage, and reimbursement of pharmaceutical and biopharmaceutical products, especially under government-funded health care programs, and increased governmental control of drug pricing. In March 2010, the Affordable Care Act, or ACA, was signed into law, which substantially changed the way healthcare is financed by both governmental and private insurers in the U.S., and significantly affected the pharmaceutical industry. The ACA contains a number of provisions of particular importance to the pharmaceutical and biotechnology industries, including, but not limited to, those governing enrollment in federal healthcare programs, a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected, and annual fees based on pharmaceutical companies’ share of sales to federal health care programs. Since its enactment, there have been judicial, Congressional, and executive branch challenges to certain aspects of the ACA. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA. Other legislative changes have been proposed and adopted since the ACA was enacted, including aggregate reductions of Medicare payments to providers of 2% per fiscal year, which was temporarily suspended from May 1, 2020, through March 31, 2022, and reduced payments to several types of Medicare providers. Moreover, there has recently been heightened governmental scrutiny over the way manufacturers set prices for their marketed products, which has resulted in several Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drug products. At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. Data Privacy and Security Laws Numerous state, federal and foreign laws, regulations, and standards govern the collection, use, access to, confidentiality and security of health- related and other personal information and could apply now or in the future to our operations or the operations of our partners. In the U.S., numerous federal and state laws and regulations, including data breach notification laws, health information privacy and security laws and consumer protection laws and regulations govern the collection, use, disclosure, and protection of health-related and other personal information. In addition, certain foreign laws govern the privacy and security of personal data, including health-related data. For example, the European Union General Data Protection Regulation, or GDPR, imposes strict requirements for processing the personal data of individuals within the European Economic Area, or EEA. Companies that must comply with the GDPR face increased compliance obligations and risk, including more robust regulatory enforcement of data protection requirements and potential fines for noncompliance of up to €20 million or 4% of the annual global revenues of the noncompliant company, whichever is greater. Further, from January 1, 2021, companies have had to comply with the GDPR and the United Kingdom GDPR, or UK GDPR, which, together with the amended United Kingdom Data Protection Act 2018, retains the GDPR in United Kingdom, or UK, national law. The UK GDPR mirrors the fines under the GDPR, i.e., fines up to the greater of €20 million (£17.5 million) or 4% of global turnover. Privacy and security laws, regulations, and other obligations are constantly evolving, may conflict with each other to complicate compliance efforts, and can result in investigations, proceedings, or actions that lead to significant civil and/or criminal penalties and restrictions on data processing. Merger On March 6, 2019, we, then operating as GTx, Inc., or GTx, entered into an Agreement and Plan of Merger and Reorganization, as amended, or the Merger Agreement, with privately-held Oncternal Therapeutics, Inc., or Private Oncternal, and Grizzly Merger Sub, Inc., our wholly-owned subsidiary, or Merger Sub. Under the Merger Agreement, Merger Sub merged with and into Private Oncternal, with Private Oncternal surviving as our wholly-owned subsidiary (the “Merger”). On June 7, 2019, the Merger was completed. GTx changed its name to Oncternal 51 Therapeutics, Inc., and Private Oncternal, which remains as our wholly-owned subsidiary, changed its name to Oncternal Oncology, Inc. On June 10, 2019, the combined company’s common stock began trading on The Nasdaq Capital Market under the ticker symbol “ONCT.” Human Capital As of March 4, 2022, we had 26 full-time employees, three part-time employees, and several consultants, most of whom are engaged in research and development activities. None of our employees are represented by labor unions or covered by collective bargaining agreements. We consider our relationship with our employees to be good. Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, and incentivizing our management team and our clinical, scientific, and other employees and consultants. The principal purposes of our equity and cash incentive plans are to attract, retain and motivate personnel through the granting of stock-based and cash-based compensation awards, to align our interests and the interests of our stockholders with those of our employees and consultants. Facilities Our corporate headquarters are in San Diego, California, where we currently lease 4,677 square feet of office space available for corporate, research, development, clinical, regulatory, manufacturing and quality functions. Corporate Information We were incorporated under the name Genotherapeutics, Inc. in Tennessee in September 1997. We changed our name to GTx, Inc. in 2001 and reincorporated in Delaware in 2003. On June 7, 2019, the Merger was completed and GTx, Inc. changed its name to Oncternal Therapeutics, Inc.

You should consider carefully the following risk factors, together with the other information contained in this Annual Report, including our financial statements and the related notes and “Management Discussion and Analysis of Financial Condition and Results of Operations,” before making a decision to purchase or sell shares of our common stock. We cannot assure you that any of the events discussed in the risk factors below will not occur. If any of the following events actually occur, our business, operating results, prospects or financial condition could be materially and adversely affected. This could cause the trading price of our common stock to decline and you may lose all or part of your investment. The risks described below are not the only ones that we face. Additional risks not presently known to us or that we currently deem immaterial may also affect our business operations or financial condition. Risks Related to Our Limited Operating History, Financial Position and Capital Requirements We have a limited operating history, have incurred significant operating losses since our inception and expect to incur significant losses for the foreseeable future. We may never generate any revenue or become profitable or, if we achieve profitability, we may not be able to sustain it. Biopharmaceutical product development is a highly speculative undertaking and involves a substantial degree of risk. We are a clinical-stage biopharmaceutical company with a limited operating history upon which you can evaluate our business and prospects. To date, we have focused primarily on organizing and staffing our company, business planning, raising capital, identifying, acquiring and in-licensing our product candidates and conducting preclinical studies and early-stage clinical trials. Zilovertamab and ONCT-216 are in clinical development, while our ROR1 CAR-T and DAARI programs are in the preclinical stage. We have not yet demonstrated an ability to successfully obtain regulatory approvals, manufacture a commercial scale product, or arrange for a third-party to do so on our behalf, or embark on sales and marketing activities necessary for successful post regulatory approval product commercialization, and have not developed any companion diagnostic test for our product candidates. Consequently, any predictions made about our future success or viability may not be as accurate as they could be if we had a history of successfully developing and commercializing biopharmaceutical products. We have incurred significant operating losses since our inception. If our product candidates are not successfully developed and approved, we may never generate any revenue. Our net losses were $31.3 million and $17.2 million for the years ended December 31, 2021, and 2020, respectively. As of December 31, 2021, we had an accumulated deficit of $114.1 million. Substantially all of our losses have resulted from expenses incurred in connection with our research and development programs and from general and administrative costs associated with our operations. All of our product candidates will require substantial additional development time and resources before we would be able to apply for or receive regulatory approvals and begin generating revenue from product sales. We expect to continue to incur losses for the foreseeable future, and anticipate these losses will increase substantially as we continue to develop, seek regulatory approval for and potentially commercialize any of our product candidates, and seek to identify, assess, acquire, in- license or develop additional product candidates. To become and remain profitable, we must succeed in developing and eventually commercializing products that generate significant revenue. This will require us to be successful in a range of challenging activities, including completing clinical trials and preclinical studies of our product candidates, obtaining regulatory approval for these product candidates and manufacturing, marketing, and selling any products for which we may obtain regulatory approval. We are only in the preliminary stages of most of these activities. We may never succeed in these activities and, even if we do, may never generate revenues that are significant enough to achieve profitability. In addition, we have not yet demonstrated an ability to successfully overcome many of the risks and uncertainties frequently encountered by companies in new and rapidly evolving fields, particularly in the biopharmaceutical industry. Because of the numerous risks and uncertainties associated with biopharmaceutical 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. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable would depress our value and could impair our ability to raise capital, expand our business, maintain our research and development efforts, diversify our product candidates or even continue our operations. A decline in our company’s value could also cause stockholders to lose all or part of their investment. 53 We will require substantial additional financing to achieve our goals, and a failure to obtain this necessary capital when needed and on acceptable terms, or at all, could force us to delay, limit, reduce or terminate our product development programs, commercialization efforts or other operations. The development of biopharmaceutical product candidates is capital-intensive. We expect our expenses to increase in connection with our ongoing activities, particularly as we conduct our ongoing and planned clinical trials of zilovertamab and ONCT-216, continue research and development and initiate clinical trials of our other development programs, including our preclinical ROR1 CAR-T and DAARI programs, and seek regulatory approval for our current product candidates and any future product candidates we may develop. In addition, as our product candidates progress through development and toward commercialization, we will need to make milestone payments to the licensors and other third parties from whom we have in-licensed or acquired our product candidates, including zilovertamab, ONCT-216, and any candidates from our ROR1 CAR-T and DAARI programs. If we obtain regulatory approval for any of our product candidates, we also expect to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution and we will need to make royalty payments to the licensors and / or other third parties from whom we have in-licensed or acquired our product candidates. Because the outcome of any clinical trial or preclinical study is highly uncertain, we cannot reasonably estimate the actual amounts necessary to successfully complete the development and commercialization of our product candidates. Furthermore, we incur additional costs associated with operating as a public company. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, reduce or eliminate our research and development programs or any future commercialization efforts. We have based our estimates on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect. Our operating plans and other demands on our cash resources may change as a result of many factors currently unknown to us, and we may need to seek additional funds sooner than planned, through a combination of equity financings, debt financings, government funding or other capital sources, including potentially collaborations, licenses and other similar arrangements. In addition, we may seek additional capital due to favorable market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. Attempting to secure additional financing may divert our management from our day-to-day activities, which may adversely affect our ability to develop our product candidates. Our future capital requirements will depend on many factors, including: • • • • • • • • • • • the costs incurred as a result of the COVID-19 pandemic, including clinical trial delays and impacts on our supply chain activities; the type, number, scope, progress, expansions, results, costs and timing of our clinical trials of zilovertamab and ONCT-216, and preclinical studies or clinical trials of our ROR1 CAR-T and DAARI programs or additional indications of our current product candidates as well as other product candidates that we may choose to pursue in the future; the costs and timing of manufacturing for our product candidates, including commercial manufacturing if any product candidate is approved; the costs of obtaining ibrutinib, for which we currently obtain supply at no cost under our clinical supply agreement with Pharmacyclics LLC, to conduct our clinical trials of zilovertamab; the costs and capacity for CAR-T development and lentivirus manufacturing; the costs, timing and outcome of regulatory review of our product candidates; the costs of obtaining, maintaining and enforcing our patents and other intellectual property rights; our efforts to enhance operational systems and hire additional personnel to satisfy our obligations as a public company, including enhanced internal controls over financial reporting; the costs associated with hiring additional personnel, contract research organizations, or CROs and consultants as our clinical and other development activities increase; the timing and amount of the milestone or other payments we must make to the licensors and other third parties from whom we have in- licensed or acquired our product candidates or technology; the costs and timing of establishing or securing sales and marketing capabilities if any of our product candidates are approved; 54 • • • our ability to achieve sufficient market acceptance, coverage and adequate reimbursement from third-party payors and adequate market share and revenue for any approved products; the terms and timing of establishing and maintaining collaborations, licenses and other similar arrangements; and costs associated with any products or technologies that we may in-license or acquire. Conducting clinical trials and preclinical studies is a time consuming, expensive, and uncertain process that takes years to complete, and we may never generate the necessary data or results required to obtain regulatory approval and achieve product sales. In addition, our product candidates, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of products that we do not expect to be commercially available for many years, if at all. Accordingly, we will need to continue to rely on additional financing to achieve our business objectives. Adequate additional financing may not be available to us on acceptable terms, or at all. In addition, we may seek additional capital due to favorable market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating plans. In April 2021, our Form S-3 registration statement became effective. Future sales under a Form S-3, if any, will depend on a variety of factors including, but not limited to, the effectiveness of a Form S-3, prevailing market conditions, the trading price of our common stock and our capital needs. If we are successful in filing a Form S-3 in the future, there can be no assurance that we will be successful in consummating future sales based on prevailing market conditions or in the quantities or at the prices that we deem appropriate. Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to our technologies or product candidates. Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through equity offerings, debt financings, government funding or other capital sources, including potentially collaborations, licenses and other similar arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, existing stockholders’ ownership interest will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect stockholders’ rights as a common stockholder. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise funds through future collaborations, licenses and other similar arrangements, we may have to relinquish valuable rights to our future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us and/or that may reduce the value of our common stock. Risks Related to the Discovery, Development and Regulatory Approval of Our Product Candidates We depend heavily on the success of our product candidates, which are in clinical or preclinical development. If we are unable to advance our product candidates in clinical development, obtain regulatory approval and ultimately commercialize our product candidates, or experience significant delays in doing so, our business will be materially harmed. Our two clinical-stage product candidates are zilovertamab, which we expect to initiate a Phase 3 clinical study in the second quarter of 2022, and ONCT-216 which is in a Phase 1/2 clinical study. In addition, zilovertamab is being evaluated in two investigator-sponsored studies being conducted at UC San Diego, a: (i) Phase 1b clinical trial in combination with docetaxel for the treatment of metastatic castration-resistant prostate cancer is about to open at UC San Diego, has an Investigational New Drug Application, or IND, in effect, to evaluate the safety and efficacy of, and to determine the RP2D, and (ii) a Phase 2 clinical trial of zilovertamab in combination with venetoclax, a Bcl-2 inhibitor, in patients with relapsed/refractory CLL is open for enrollment. We are also developing ONCT-216, an investigational small molecule that is designed to inhibit the ETS, or E26 Transformation Specific, family of oncoproteins, which have been shown in preclinical studies to alter gene transcription and RNA processing and lead to increased cell proliferation and invasion. ONCT-216 is being evaluated in a Phase 1/2 clinical trial as a single agent and in combination with vincristine 55 in patients with relapsed or refractory Ewing sarcoma, a rare pediatric cancer. In addition, we are developing ONCT-808, a chimeric antigen receptor T cell, or CAR-T, therapy candidate that targets ROR1, which is currently in preclinical development as a potential treatment for hematologic cancers and solid tumors. Our pipeline also includes ONCT-534, an investigational dual-action androgen receptor inhibitor, that is in preclinical development as a potential treatment for castration resistant prostate cancer and other androgen-receptor dependent diseases. None of our product candidates have advanced into a pivotal or registrational study for the indications for which we are studying them, although we expect the planned Phase 3 trial of zilovertamab for the treatment of patients with MCL to be a potentially pivotal trial. Our ability to generate product revenues, which we do not expect will occur for many years, if ever, will depend heavily on the successful development and eventual commercialization of our product candidates. The success of our product candidates will depend on various factors, including the following: • • • • • • • • • • successful completion of preclinical and clinical studies with favorable results; acceptance of investigation new drug applications, or INDs, by the FDA, or similar regulatory filing by comparable foreign regulatory authorities for the conduct of clinical trials of our product candidates and our proposed designs for future clinical trials; demonstrating safety and efficacy of our product candidates to the satisfaction of applicable regulatory authorities; receiving marketing approvals from applicable regulatory authorities, including Biologics License Applications, or BLAs, or new drug applications, or NDAs, from the FDA, and maintaining such approvals; making arrangements with our third-party manufacturers for commercial manufacturing capabilities and manufacturing process optimization for our product candidates; establishing sales, marketing and distribution capabilities and launching commercial sales of our product candidates, if and when approved, whether alone or in collaboration with others; establishing and maintaining patent and trade secret protection or regulatory exclusivity for our product candidates; the demonstration of an acceptable safety profile of our products following approval, if any; developing, in-licensing or acquiring companion diagnostics to our product candidates; and maintaining and growing an organization for people who can develop our product candidates and technology. The success of our business, including our ability to finance the company and generate any revenue in the future, will primarily depend on the successful development, regulatory approval and commercialization of our product candidates, which may never occur. We have not yet succeeded and may not succeed in demonstrating efficacy and safety for any of our product candidates in clinical trials or in obtaining marketing approval thereafter. Given our early-stage of development, it may be several years, if at all, before we have demonstrated the safety and efficacy of a product candidate sufficient to warrant approval for commercialization. If we are unable to develop, or obtain regulatory approval for, or, if approved, successfully commercialize our product candidates, we may not be able to generate sufficient revenue to continue our business. Clinical drug development involves a lengthy and expensive process with an uncertain outcome, and the results of preclinical studies and early clinical trials are not necessarily predictive of future results. Our product candidates may not have favorable results in clinical trials or receive regulatory approval on a timely basis, if at all. Clinical drug development is expensive and can take many years to complete, and its outcome is inherently uncertain. We cannot guarantee that any clinical trials will be conducted as planned or completed on schedule, if at all, and failure can occur at any time during the preclinical study or clinical trial process. Despite promising preclinical or clinical results, any product candidate can unexpectedly fail at any stage of preclinical or clinical development. The historical failure rate for product candidates in our industry is high. The results from preclinical studies or clinical trials of a product candidate may not predict the results of later clinical trials of the product candidate, and interim results of a clinical trial are not necessarily indicative of final results. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy characteristics despite having progressed through preclinical studies and initial clinical trials. In particular, while zilovertamab was well tolerated and showed favorable results in the Phase 1 portion of our ongoing Phase 1/2 clinical trial as well as the inhibition of ROR1 signaling in patients with CLL in early clinical trials, we do not know how zilovertamab will perform in the Phase 2 portion of the clinical trial and one or more of the reported clinical 56 outcomes may materially change as patient enrollment continues in such trial, and such results may not be replicated in any other future clinical trials, including as a result of any differences in the target population, drug interactions or other differences in our trial design. It is not uncommon to observe results in clinical trials that are unexpected based on preclinical studies and early clinical trials, and many product candidates fail in clinical trials despite very promising early results. Moreover, this and any future preclinical and clinical data may be susceptible to varying interpretations and analyses. 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. Furthermore, we cannot assure you that we will be able to successfully progress our preclinical programs from candidate identification to Phase 1 clinical development. For the foregoing reasons, we cannot be certain that our ongoing and planned clinical trials and preclinical studies will be successful. Any safety concerns observed in any one of our clinical trials in our targeted indications could limit the prospects for regulatory approval of our product candidates in those and other indications, which could have a material adverse effect on our business, financial condition and results of operations. In addition, the FDA’s and other regulatory authorities’ policies with respect to clinical trials may change and additional government regulations may be enacted. For instance, the regulatory landscape related to clinical trials in the European Union, or EU, recently evolved. The EU Clinical Trials Regulation, or CTR, which was adopted in April 2014 and repeals the EU Clinical Trials Directive, became applicable on January 31, 2022. While the Clinical Trials Directive required a separate clinical trial application, or CTA, to be submitted in each member state, to both the competent national health authority and an independent ethics committee, the CTR introduces a centralized process and only requires the submission of a single application to all member states concerned. The CTR allows sponsors to make a single submission to both the competent authority and an ethics committee in each member state, leading to a single decision per member state. The assessment procedure of the CTA has been harmonized as well, including a joint assessment by all member states concerned, and a separate assessment by each member state with respect to specific requirements related to its own territory, including ethics rules. Each member state’s decision is communicated to the Sponsor via the centralized EU portal. Once the CTA is approved, clinical study development may proceed. The CTR foresees a three-year transition period. The extent to which clinical trials will be governed by the CTR varies. For clinical trials whose CTA was made under the Clinical Trials Directive before January 31, 2022, the Clinical Trials Directive will continue to apply on a transitional basis for three years. Additionally, sponsors may still choose to submit a CTA under either the Clinical Trials Directive or the CTR until January 31, 2023 and, if authorized, those will be governed by the Clinical Trials Directive until January 31, 2025. By that date, all ongoing trials will become subject to the provisions of the CTR. It is currently unclear to what extent the United Kingdom, or UK, will seek to align its regulations with the EU. The UK regulatory framework in relation to clinical trials is derived from existing EU legislation (as implemented into UK law, through secondary legislation). A decision by the UK not to closely align its regulations with the new approach that will be adopted in the EU may have an effect on the cost of conducting clinical trials in the UK as opposed to other countries and/or make it harder to seek a marketing authorization in the EU for our product candidates on the basis of clinical trials conducted in the UK. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies governing clinical trials, our development plans may be impacted. The COVID-19 pandemic may adversely impact our business. The duration, extent, and impact of the ongoing COVID-19 pandemic remains uncertain, has presented substantial public health and economic challenges and continues to affect economies, financial markets and business operations around the world. International and U.S. governmental authorities have taken actions since late 2019 in an effort to slow the spread of COVID-19, including issuing varying forms of “stay-at-home” orders, and restricting business functions outside of one’s home. We expect that COVID-19 precautions may continue to directly or indirectly affect the timeline for our clinical trials, including our global Phase 3 study of zilovertamab that we plan to initiate in the second quarter of 2022 and our expected submission of an IND for our ROR1 CAR-T program during the middle of 2022. Patients with MCL or CLL may be at increased risk of severe disease if they develop COVID-19 because of advanced age and/or immunosuppression, and so may be unwilling to travel to our study centers to enroll in our clinical trials. For our existing patients, we continue to work all of our clinical trial sites to 57 minimize disruptions and address concerns on an individual site or patient basis in order to allow participating patients to continue to receive treatment at home or in alternate healthcare settings while minimizing their potential exposure to the virus that causes COVID-19. At the present time, we believe we have sufficient quantities of our zilovertamab and ONCT-216 clinical trial materials to continue to treat patients in our clinical trials through at least the end of 2022. However, if our third-party manufacturers, including those located in China, experience additional manufacturing difficulties due to the COVID-19 pandemic or as a result of natural disasters, labor disputes, unstable political environments, or other public health emergencies, our ability to provide our product candidates to patients in clinical trials, or to provide product for treatment of patients if approved, would be jeopardized. The COVID-19 pandemic may cause disruptions that could severely impact our business, clinical trials and manufacturing and supply chains, including: • • • • • • • • • • • • interruptions or delays in the operations of the FDA or other regulatory authorities, which may delay receiving feedback or approvals from the FDA or other regulatory authorities with respect to future clinical trials or regulatory submissions; further delays or difficulties in enrolling patients in our clinical trials; delays or difficulties in clinical site initiation, including difficulties in recruiting clinical site investigators and clinical site staff; 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 our clinical trials; 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 or interruption of clinical trial patient visits and study procedures, which may impact the integrity of patient data and clinical study endpoints; limiting our ability to interact with our clinical trial investigators, present our data in person at scientific and investor conferences, develop and renew contracts due to travel limitations or cancellations of scientific or investor conferences; interruption of, or delays in receiving, supplies of our product candidates from our contract manufacturing organizations due to staffing shortages, production slowdowns or stoppages and disruptions in delivery systems, including interruption of supply of zilovertamab or ONCT-216; delays in clinical sites receiving the supplies and materials needed to conduct our clinical trials and interruption in global shipping that may affect the transport of clinical trial materials; limitations on employee resources that would otherwise be focused on the conduct of our clinical trials, including because of sickness of employees or their families or the desire of employees to avoid contact with large groups of people; changes in local regulations as part of a response to COVID-19 which may require us to change the ways in which our clinical trials are conducted, which may result in unexpected costs, or to discontinue the clinical trials altogether; delays in necessary interactions with local regulators, ethics committees and other important agencies and contractors due to limitations in employee resources or forced furlough of government employees; and difficulties launching or commercializing products, including due to reduced access to doctors as a result of social distancing protocols. 58 In addition, the spread of COVID-19 may have impacted, and may continue to impact, the trading price of shares of our common stock and could further severely impact our ability to raise additional capital on a timely basis, or at all, or enter into partnerships with pharmaceutical companies. The situation continues to rapidly evolve. The extent to which the COVID-19 may impact our business, including our clinical trials, manufacturing and supply chains and financial condition will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the identification of new variants, travel restrictions and social distancing in the U.S. and other countries, business closures or business disruptions and the effectiveness of actions taken in the U.S. and other countries to contain and treat the disease. To the extent the COVID-19 pandemic adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described in this section. Any difficulties or delays in the commencement or completion, or termination or suspension, of our current or planned clinical trials could result in increased costs to us, delay or limit our ability to generate revenue, and adversely affect our commercial prospects. Before obtaining marketing approval from regulatory authorities for the sale of our product candidates, we must conduct extensive clinical studies to demonstrate the safety and efficacy of the product candidates in humans. We are conducting a Phase 1/2 clinical trial of zilovertamab in combination with ibrutinib in patients with treatment-naïve or relapsed or refractory CLL and previously treated patients with MCL. Additionally, we are evaluating ONCT-216 as a single agent and in combination with vincristine in a Phase 1 clinical trial in patients with relapsed or refractory Ewing sarcoma. We will have to follow the same procedure for our other preclinical product candidates that we plan to advance to clinical development, and would also be required to submit regulatory filings to foreign regulatory authorities if we decide to initiate clinical trials outside of the U.S. We do not know whether our planned trials will begin on time or be completed on schedule, if at all. The commencement and completion of clinical trials can be delayed for a number of reasons, including delays related to: • • • • • • • • • • • • • • • • the FDA or comparable foreign regulatory authorities disagreeing as to the design or implementation of our clinical studies; difficulties in obtaining regulatory authorizations to commence a trial or reaching a consensus with regulatory authorities on trial design; difficulties in recruiting clinical trial investigators with the appropriate competencies and experience; failure or delay in reaching an agreement with CROs and clinical trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites; delays in obtaining approval from one or more institutional review boards, or IRBs, or ethics committees; IRBs refusing to approve, suspending or terminating the trial at an investigational site, precluding enrollment of additional patients, or withdrawing their approval of the trial; changes to clinical trial protocols; clinical sites deviating from trial protocols or dropping out of a trial; challenges in manufacturing sufficient quantities of product candidates or obtaining sufficient quantities of combination therapies for use in clinical trials; patients failing to enroll or remain in our trial at the rate we expect, or failing to return for post-treatment follow-up; patients choosing an alternative treatment for the indication for which we are developing our product candidates, or participating in competing clinical trials; lack of adequate funding to continue clinical trials; patients experiencing severe or unexpected drug-related adverse effects; occurrence of serious adverse events in clinical trials of the same class of agents conducted by other companies; selection of clinical endpoints that require prolonged periods of clinical observation or analysis of the resulting data; a facility manufacturing our product candidates or any of their components being ordered by the FDA or comparable foreign regulatory authorities to temporarily or permanently shut down due to violations of 59 • • • cGMP regulations or other applicable requirements, or infections or cross-contaminations of product candidates in the manufacturing process; any changes to our manufacturing process that may be necessary or desired; third-party clinical investigators losing the licenses or permits necessary to perform our clinical trials, not performing our clinical trials in a timely manner or consistent with applicable clinical trial protocols, GCP, or other regulatory requirements; third-party contractors not performing data collection or analysis in a timely or accurate manner; or third-party contractors becoming debarred or suspended or otherwise penalized by the FDA or other government or regulatory authorities for violations of regulatory requirements, in which case we may need to find a substitute contractor, and we may not be able to use some or all of the data produced by such contractors in support of our marketing applications. In addition, disruptions caused by the COVID-19 pandemic may increase the likelihood that we encounter such difficulties or delays in initiating, enrolling, conducting or completing our planned and ongoing clinical trials. We could also encounter delays if our clinical trials are suspended or terminated by us, by the IRBs of the institutions in which such trials are being conducted, by a Data Safety Monitoring Board for such trial, or by the FDA or comparable foreign regulatory authorities. Regulatory authorities may suspend or terminate clinical trials due to a number of factors, including failure to conduct clinical trials in accordance with regulatory requirements or the applicable clinical protocols, inspection of the clinical trial operations or trial site by the FDA or comparable foreign regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a drug, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. In addition, changes in regulatory requirements and policies may occur, and we may need to amend clinical trial protocols to comply with these changes. Amendments may require us to resubmit our clinical trial protocols to IRBs for reexamination, which may impact the costs, timing or successful completion of a clinical trial. Further, if we decide to conduct clinical trials of our product candidates in foreign countries additional risks may arise that may delay completion of those clinical trials. These risks include the failure of enrolled patients in other countries to adhere to clinical protocol as a result of differences in healthcare practices or cultural customs, managing additional administrative burdens associated with the regulatory schemes of other countries, as well as political and economic risks relevant to other countries. Under our license and development agreement with SPH USA, SPH USA has the right to manufacture, develop, market, distribute and sell our zilovertamab, ROR1 CAR-T, and ONCT-216 product candidates in the People’s Republic of China, Hong Kong, Macau and Taiwan, or Greater China, and the obligation to perform all preclinical and clinical development activities required to obtain regulatory approvals for such product candidates in Greater China. In the event that SPH USA’s preclinical studies or clinical trials of our product candidates raise new safety or efficacy concerns, the prospects for obtaining regulatory approval of our product candidates in the U.S. and other countries, and our business, could be adversely impacted. Moreover, principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and receive compensation in connection with such services. Under certain circumstances, we may be required to report some of these relationships to the FDA or comparable foreign regulatory authorities. The FDA or comparable foreign regulatory authority may conclude that a financial relationship between us and a principal investigator has created a conflict of interest or otherwise affected interpretation of the study. The FDA or comparable foreign regulatory authority may therefore question the integrity of the data generated at the applicable clinical trial site and the utility of the clinical trial itself may be jeopardized. This could result in a delay in approval, or rejection, of our marketing applications by the FDA or comparable foreign regulatory authority, as the case may be, and may ultimately lead to the denial of marketing approval of one or more of our product candidates. If we experience delays in the completion of, or termination of, clinical trials of our product candidates, the commercial prospects of such product candidates may be harmed, and our ability to generate product revenues from such product candidates may be delayed. Moreover, delays in completing our clinical trials may increase our costs, slow down our product candidate development and approval process and jeopardize our ability to commence product sales and generate revenues. 60 In addition, many of the factors that cause, or lead to, the termination, suspension or delay in the commencement or completion of, clinical trials may also ultimately lead to the denial of regulatory approval of a product candidate. If we make formulation or manufacturing changes to our product candidates or revise the route of administration or dosing regimen for our product candidates, we may be required to conduct additional preclinical or clinical studies to bridge our modified product candidates to earlier versions or to bridge the new dosing regimens to dosing regimens used in our clinical trials. The need to conduct additional preclinical or clinical studies could result in delays in the approval or commercialization of our product candidates, which could shorten any period during which we may have the exclusive right to commercialize our product candidates and enable our competitors to bring products to market before we do. In such an event, the commercial viability of our product candidates could be significantly reduced. Any of these occurrences may harm our business, financial condition and prospects significantly. We may find it difficult to enroll patients in our clinical trials. If we encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed or otherwise adversely affected. We may not be able to initiate or continue clinical trials for our product candidates if we are unable to identify and enroll a sufficient number of eligible patients to participate in these trials as required by the FDA or similar regulatory authorities outside the U.S. 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 patients to clinical sites, the eligibility and exclusion criteria for the trial, the design of the clinical trial, the availability of competing clinical trials and clinicians’ and patients’ perceptions as to the potential advantages and risks of the product candidate being studied in relation to other available therapies, including any new drugs that may be approved for the indications we are investigating as well as any drugs under development. We will be required to identify and enroll a sufficient number of patients for each of our clinical trials. Potential patients for any planned clinical trials may not be adequately diagnosed or identified with the diseases which we are targeting or may not meet the entry criteria for such trials. For example, a limited number of patients are affected by CLL, MCL and particularly Ewing sarcoma, which are our initial target indications for zilovertamab and ONCT-216. We also may encounter difficulties in identifying and enrolling patients with a stage of disease appropriate for our planned clinical trials. We may not be able to initiate or continue clinical trials if we are unable to locate a sufficient number of eligible patients to participate in the clinical trials required by the FDA or comparable foreign regulatory authorities. In addition, the process of finding and diagnosing patients may prove costly. The timing of our clinical trials depends, in part, on the speed at which we can recruit patients to participate in our trials, as well as completion of required follow-up periods. For certain of our product candidates, including zilovertamab and ONCT-216, the conditions which we currently plan to evaluate are orphan or rare diseases with limited patient pools from which to draw for clinical trials. The eligibility criteria of our clinical trials will further limit the pool of available trial participants. If patients are unwilling to participate in our clinical trials for any reason, including the existence of concurrent clinical trials for similar patient populations or the availability of approved therapies, or if we otherwise have difficulty enrolling a sufficient number of patients, the timeline for recruiting patients, conducting studies and obtaining regulatory approval of our product candidates may be delayed. Our inability to enroll a sufficient number of patients for any of our clinical trials would result in significant delays or may require us to abandon one or more clinical trials altogether. In addition, we expect to rely on CROs and clinical trial sites to ensure proper and timely conduct of our future clinical trials and, while we intend to enter into agreements governing their services, we will have limited influence over their actual performance. We cannot assure stockholders that our assumptions used in determining expected clinical trial timelines are correct or that we will not experience delays in enrollment, which would result in the delay of completion of such trials beyond our expected timelines. 61 Use of our product candidates could be associated with side effects, adverse events or other properties or safety risks, which could delay or preclude approval, cause us to suspend or discontinue clinical trials, abandon a product candidate, limit the commercial profile of the label for an approved product candidate, or result in other significant negative consequences that could severely harm our business, prospects, operating results and financial condition. As is the case with oncology drugs generally, it is likely that there may be side effects and adverse events associated with the use of our product candidates. Results of our clinical trials could reveal a high and unacceptable severity and prevalence, or unexpected characteristics of side effects. For example, our ongoing clinical trials of zilovertamab in combination with ibrutinib, and ONCT-216 in combination with vincristine, and the ongoing investigator-initiated clinical trial of zilovertamab in combination with paclitaxel, may reveal adverse events based on the combination therapy under evaluation. Undesirable side effects caused by our product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials, result in a more restrictive label for the product candidate, or delay or cause the denial of regulatory approval of the product candidate by the FDA or comparable foreign regulatory authorities. The drug-related side effects could also affect patient recruitment for our clinical trials, or the ability of enrolled patients to complete the trials, or result in potential product liability claims. Any of these occurrences may harm our business, financial condition and prospects significantly. Moreover, if our product candidates are associated with undesirable side effects in clinical trials or have characteristics that are unexpected, we may elect to abandon their development or limit their development to more narrow uses or subpopulations in which the undesirable side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective, which may limit the commercial prospects for the product candidate if approved. We may also be required to modify our plans for future studies based on findings in our ongoing clinical trials. Many compounds that initially showed promise in early-stage testing have later been found to cause side effects that prevented further development of the compound. In addition, regulatory authorities may draw different conclusions or require additional testing to confirm these determinations. It is possible that as we test our product candidates in larger, longer and more extensive clinical trials, or as the use of our product candidates becomes more widespread if they receive regulatory approval, illnesses, injuries, discomforts and other adverse events that were observed in earlier trials, as well as conditions that did not occur or went undetected in previous trials, will be reported by patients. If such side effects become known later in development or upon approval, if any, such findings may harm our business, financial condition and prospects significantly. In addition, if one or more of our product candidates receives marketing approval, and we or others later identify undesirable side effects caused by such products, a number of potentially significant negative consequences could result, including: • • • • • • • • regulatory authorities may withdraw, suspend or limit approvals of such product; we may be required to recall a product or change the way such product is administered to patients; regulatory authorities may require additional warnings on the label, such as a “black box” warning or a contraindication; we may be required to implement a Risk Evaluation and Mitigation Strategy, or REMS, or create a medication guide outlining the risks of such side effects for distribution to patients or similar risk management measures; we may be required to change the way a product is distributed or administered, conduct additional clinical trials or change the labeling of a product or be required to conduct additional post-marketing studies or surveillance; we could be sued and held liable for harm caused to patients; sales of the product may decrease significantly or the product could become less competitive; and our reputation could suffer. Any of these events could prevent us from achieving or maintaining market acceptance of the particular product candidate, if approved, and could significantly harm our business, results of operations and prospects. 62 We may not be able to maintain orphan drug designations for certain of our product candidates, and may be unable to maintain the benefits associated with orphan drug designation, including the potential for market exclusivity. Regulatory authorities in some jurisdictions, including the U.S. and EU, may designate drugs for relatively small patient populations as orphan drugs. Under the Orphan Drug Act of 1983, the FDA may designate a product candidate as an orphan product if it is intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals in the U.S., or a patient population of greater than 200,000 individuals in the U.S., but for which there is no reasonable expectation that the cost of developing the drug will be recovered from sales in the U.S. In the EU, orphan drug designation is granted by the European Commission based on a scientific opinion of the European Medicines Agency’s, or EMA, Committee for Orphan Medicinal Products. A medicinal product may be designated as orphan if its Sponsor can establish that (i) the product is intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition; (ii) either (a) such condition affects no more than 5 in 10,000 persons in the EU when the application is made, or (b) the product, without the benefits derived from orphan status, would not generate sufficient return in the EU to justify investment; and (iii) there exists no satisfactory method of diagnosis, prevention or treatment of such condition authorized for marketing in the EU, or if such a method exists, the medicinal product will be of significant benefit to those affected by the condition. The application for orphan designation must be submitted before the application for marketing authorization. In June 2020, we announced that we had obtained orphan drug designations in the U.S. for zilovertamab for treatment of MCL and for treatment of CLL/small lymphocytic lymphoma. We have also received orphan drug designation in the U.S. for ONCT-216 for patients with Ewing sarcoma. We may seek additional orphan drug designations for zilovertamab or ONCT- 216 or for certain of our other product candidates. There can be no assurance that the FDA or the European Commission will grant orphan designation for any indication for which we apply, or that we will be able to maintain such designation. In the U.S., orphan designation entitles a party to financial incentives such as opportunities for grant funding for clinical trial costs, tax advantages and user-fee waivers. In addition, if a product candidate that has orphan designation subsequently receives the first FDA approval for the disease for which it has such designation, the product is entitled to orphan drug exclusivity, which means that the FDA may not approve any other applications, including a NDA or BLA, to market the same drug for the same indication for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan drug exclusivity or where the manufacturer is unable to assure sufficient product quantity. The applicable exclusivity period is ten years in the EU, but such exclusivity period can be reduced to six years if, at the end of the fifth year, it is established that the product no longer meets the criteria for which it received orphan designation, including where it is shown that the product is sufficiently profitable not to justify maintenance of market exclusivity, or where the prevalence of the condition has increased above the threshold. Even if we obtain orphan drug exclusivity for a product, that exclusivity may not effectively protect the product from competition because different drugs can be approved for the same condition. Even after an orphan drug is approved, the FDA or comparable foreign regulatory authority can subsequently approve the same drug for the same condition if such regulatory authority concludes that the later drug is clinically superior if it is shown to be safer, more effective or makes a major contribution to patient care. 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. The regulatory landscape that will apply to development of gene therapy or cell-based therapeutic product candidates by us or by our collaborators is rigorous, complex, uncertain and subject to change, which could result in delays or termination of development of such product candidates or unexpected costs in obtaining regulatory approvals. Regulatory requirements governing products involving gene therapy treatment have changed frequently and will likely continue to change in the future. Approvals by one regulatory agency may not be indicative of what any other regulatory agency may require for approval, and there is substantial, and sometimes uncoordinated, overlap in those responsible for regulation of gene therapy products, cell therapy products and other products created with genome editing technology. For example, in addition to the submission of an IND to the FDA, before initiation of a clinical trial in the U.S., certain human clinical trials for cell therapy products and gene therapy are subject to the National Institutes of Health Guidelines for Research Involving Recombinant DNA Molecules, or NIH Guidelines. 63 The NIH Guidelines call for the supervision of human gene transfer trials including an evaluation and assessment by an institutional biosafety committee, or IBC, a local institutional committee that reviews and oversees research utilizing recombinant or synthetic nucleic acid molecules at that institution. The IBC assesses the safety of the research and identifies any potential risk to public health or the environment, and such review may result in some delay before initiation of a clinical trial. While the NIH Guidelines are not mandatory unless the research in question is being conducted at or sponsored by institutions receiving NIH funding of recombinant or synthetic nucleic acid molecule research, many companies and other institutions not otherwise subject to the NIH Guidelines voluntarily follow them. We will therefore be subject to significant regulatory oversight by the FDA, and in addition to the government regulators, the applicable IBC and IRB of each institution at which we or our collaborators conduct clinical trials of our product candidates, or a central IRB if appropriate, would need to review and approve the proposed clinical trial. Similar requirements apply in the EU. The EMA, has a Committee for Advanced Therapies, or CAT, that is responsible for assessing the quality, safety and efficacy of advanced therapy medicinal products, or ATMPs. ATMPs include gene therapy medicine, somatic-cell therapy medicines and tissue- engineered medicines. The role of the CAT is to prepare a draft opinion on an application for marketing authorization for a gene therapy medicinal candidate that is submitted to the EMA. In the EU, the development and evaluation of a gene therapy medicinal product must be considered in the context of the relevant EU guidelines. The EMA may issue new guidelines concerning the development and marketing authorization for gene therapy medicinal products and require that we comply with these new guidelines. Similarly complex regulatory environments exist in other jurisdictions in which we might consider seeking regulatory approvals for our product candidates, further complicating the regulatory landscape. As a result, the procedures and standards applied to gene therapy products and cell therapy products may be applied to any of our gene therapy product candidates such as CAR-T, but that remains uncertain at this point. The clinical trial requirements of the FDA, the EMA and other regulatory authorities and the criteria these regulators use to evaluate the safety and efficacy of a product candidate vary substantially according to the type, complexity, novelty and intended use and market of the potential products. The regulatory approval process for product candidates involving gene therapy can be more lengthy, rigorous and expensive than the process for other better known or more extensively studied product candidates and technologies. Since we are developing novel treatments for diseases in which there is little clinical experience with new endpoints and methodologies, there is heightened risk that the FDA, the EMA or comparable regulatory bodies may not consider the clinical trial endpoints to provide clinically meaningful results, and the resulting clinical data and results may be more difficult to analyze. This may be a particularly significant risk for many of the genetically defined diseases for which we may develop product candidates alone or with collaborators due to small patient populations for those diseases, and designing and executing a rigorous clinical trial with appropriate statistical power is more difficult than with diseases that have larger patient populations. Regulatory agencies administering existing or future regulations or legislation may not allow production and marketing of products utilizing gene therapy in a timely manner or under technically or commercially feasible conditions. Even if our product candidates obtain required regulatory approvals, such approvals may later be withdrawn as a result of changes in regulations or the interpretation of regulations by applicable regulatory agencies. Additionally, adverse developments in clinical trials of gene therapy products conducted by others may cause the FDA, the EMA and other regulatory bodies to revise the requirements for approval of any product candidates we may develop or limit the use of products utilizing gene therapy, either of which could materially harm our business. Furthermore, regulatory action or private litigation could result in increased expenses, delays or other impediments to our research programs or the development or commercialization of current or future product candidates. Delay or failure to obtain, or unexpected costs in obtaining, the regulatory approval necessary to bring a product candidate to market could decrease our ability to generate sufficient product revenue to maintain our business. As an organization, we have limited experience in the process of enrolling patients in our clinical trials, have never conducted later-stage clinical trials or submitted a BLA or an NDA, and may be unable to do so for any of our product candidates. Similar requirements apply in the EU. The EMA, has a Committee for Advanced Therapies, or CAT, that is responsible for assessing the quality, safety and efficacy of advanced therapy medicinal products, or ATMPs. ATMPs include gene therapy medicine, somatic-cell therapy medicines and tissue- engineered medicines. The role of the CAT is to prepare a draft opinion on an application for marketing authorization for a gene therapy medicinal 64 candidate that is submitted to the EMA. In the EU, the development and evaluation of a gene therapy medicinal product must be considered in the context of the relevant EU guidelines. The EMA may issue new guidelines concerning the development and marketing authorization for gene therapy medicinal products and require that we comply with these new guidelines. Similarly complex regulatory environments exist in other jurisdictions in which we might consider seeking regulatory approvals for our product candidates, further complicating the regulatory landscape. As a result, the procedures and standards applied to gene therapy products and cell therapy products may be applied to any of our gene therapy product candidates such as CAR-T, but that remains uncertain at this point. Our product candidates are subject to extensive regulation and compliance, which is costly and time consuming, and such regulation may cause unanticipated delays or prevent the receipt of the required approvals to commercialize our product candidates. The clinical development, manufacturing, labeling, storage, record-keeping, advertising, promotion, import, export, marketing and distribution of our product candidates are subject to extensive regulation by the FDA in the U.S. and by comparable foreign regulatory authorities in foreign markets. In the U.S., we are not permitted to market our product candidates until we receive regulatory approval from the FDA. The process of obtaining regulatory approval is expensive, often takes many years following the commencement of clinical trials and can vary substantially based upon the type, complexity and novelty of the product candidates involved, as well as the target indications and patient population. Approval policies or regulations may change, and the FDA has substantial discretion in the drug approval process, including the ability to delay, limit or deny approval of a product candidate for many reasons. Despite the time and expense invested in clinical development of product candidates, regulatory approval is never guaranteed. We are not permitted to market any of our product candidates in the U.S. until we receive approval of a BLA or an NDA from the FDA. Similar risks exist in foreign jurisdictions. Prior to obtaining approval to commercialize a product candidate in the U.S. or abroad, we must demonstrate with substantial evidence from adequate and well-controlled clinical trials, and to the satisfaction of the FDA or comparable foreign regulatory authorities, that such product candidates are safe and effective for their intended uses, and in the case of biological products, that such product candidates are safe, pure and potent. Results from nonclinical studies and clinical trials can be interpreted in different ways. Even if we believe the nonclinical or clinical data for our product candidates are promising, such data may not be sufficient to support approval by the FDA and comparable foreign regulatory authorities. The FDA or comparable foreign regulatory authorities, as the case may be, may also require us to conduct additional preclinical studies or clinical trials for our product candidates either prior to or post-approval, or may object to elements of our clinical development program. The FDA or comparable foreign regulatory authorities can delay, limit or deny approval of a product candidate for many reasons, including: • • • • • • • • • • • • such authorities may disagree with the design or execution of our clinical trials; negative or ambiguous results from our clinical trials or results may not meet the level of statistical significance required by the FDA or comparable foreign regulatory agencies for approval; serious and unexpected drug-related side effects may be experienced by participants in our clinical trials or by individuals using drugs similar to our product candidates; the population studied in the clinical trial may not be sufficiently broad or representative to assure safety in the full population for which we seek approval; such authorities may not accept clinical data from trials that are conducted at clinical facilities or in countries where the standard of care is potentially different from that of their own country; we may be unable to demonstrate that a product candidate’s clinical and other benefits outweigh its safety risks; such authorities may disagree with our interpretation of data from preclinical studies or clinical trials; such authorities may not agree that the data collected from clinical trials of our product candidates are acceptable or sufficient to support the submission of a BLA, NDA or other submission or to obtain regulatory approval in the U.S. or elsewhere, and such authorities may impose requirements for additional preclinical studies or clinical trials; such authorities may disagree with us regarding the formulation, labeling and/or the product specifications of our product candidates; approval may be granted only for indications that are significantly more limited than those sought by us, and/or may include significant restrictions on distribution and use; such authorities may find deficiencies in the manufacturing processes or facilities of the third-party manufacturers with which we contract for clinical and commercial supplies; or such authorities may not accept a submission due to, among other reasons, the content or formatting of the submission. 65 With respect to foreign markets, approval procedures vary among countries and, in addition to the foregoing risks, may involve additional product testing, administrative review periods and agreements with pricing authorities. In addition, events raising questions about the safety of certain marketed pharmaceuticals may result in increased cautiousness by the FDA and comparable foreign regulatory authorities in reviewing new drugs based on safety, efficacy or other regulatory considerations and may result in significant delays in obtaining regulatory approvals. Any delay in obtaining, or inability to obtain, applicable regulatory approvals would prevent us or any of our potential future collaborators from commercializing our product candidates. Of the large number of drugs in development, only a small percentage successfully complete the FDA or foreign regulatory approval processes and are commercialized. The lengthy approval process as well as the unpredictability of future clinical trial results may result in our failure to obtain regulatory approval to market our product candidates, which would significantly harm our business, financial condition, results of operations and prospects. Even if we eventually complete clinical trials and receive approval of a BLA, NDA or comparable foreign marketing application for our product candidates, the FDA or comparable foreign regulatory authority may grant approval contingent on the performance of costly additional clinical trials, including Phase 4 clinical trials, and/or the implementation of a REMS or similar risk management measures, which may be required because the FDA or the comparable foreign regulatory authority believes it is necessary to ensure safe use of the drug after approval. The FDA or the comparable foreign regulatory authority also may approve a product candidate for a more limited indication or patient population than we originally requested, and the FDA or comparable foreign regulatory authority may not approve the labeling that we believe is necessary or desirable for the successful commercialization of a product. Any delay in obtaining, or inability to obtain, applicable regulatory approval would delay or prevent commercialization of that product candidate and would materially adversely impact our business and prospects. We may expend our limited resources to pursue a particular product candidate and fail to capitalize on product candidates or indications that may be more profitable or for which there are a greater likelihood of success. Because we have limited financial and managerial resources, we are focused on specific product candidates, indications and development programs. As a result, we may forgo or delay the pursuit of opportunities with other indications or other product candidates that could have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future research and development programs and product candidates for specific indications may not yield any commercially viable products. If we do not accurately evaluate the commercial potential for a particular product candidate, we could relinquish valuable rights to that product candidate through collaborations, licenses and other similar arrangements, when it might be more advantageous for us to retain sole development and commercialization rights to such product candidate. Fast Track designation by the FDA for ONCT-216 or our other product candidates may not actually lead to a faster development or regulatory review or approval process. We have been granted a Fast Track designation for ONCT-216 in the U.S. for the treatment of Ewing sarcoma and may seek Fast Track designation for zilovertamab or our other product candidates. The Fast Track program is intended to expedite or facilitate the process for reviewing new product candidates that meet certain criteria. Specifically, new drugs are eligible for Fast Track designation if they are intended, alone or in combination with one or more drugs, to treat a serious or life-threatening disease or condition and demonstrate the potential to address unmet medical needs for the disease or condition. Fast Track designation applies to the combination of the product candidate and the specific indication for which it is being studied. With a Fast Track product candidate, the FDA may consider for review sections of the NDA or BLA on a rolling basis before the complete application is submitted, if the Sponsor provides a schedule for the submission of the sections of the NDA or BLA, the FDA agrees to accept sections of the NDA or BLA and determines that the schedule is acceptable, and the Sponsor pays any required user fees upon submission of the first section of the NDA or BLA. Obtaining a Fast Track designation does not change the standards for product approval, but may expedite the development or approval process. Even though the FDA has granted such designation for ONCT-216, it may not actually result in faster clinical development or regulatory review or approval. Furthermore, such a designation does not increase the likelihood that ONCT-216 or any other product candidate that may be granted Fast Track designation will receive marketing approval in the U.S. 66 We may seek PRIME designation by EMA or other designations, schemes or tools in the EU, including the conditional marketing authorization or marketing authorization under exceptional circumstances, for one or more of our product candidates, which we may not receive. Such designations may not lead to a faster development or regulatory review or approval process and do not increase the likelihood that our product candidates will receive marketing authorization. We may seek EMA PRIME (Priority Medicines) designation or other designations, schemes or tools for one or more of our product candidates. In the EU, innovative products that target an unmet medical need and are expected to be of major public health interest may be eligible for a number of expedited development and review programs, such as the PRIME scheme, which provides incentives similar to the Breakthrough Therapy designation in the U.S. PRIME is a voluntary scheme aimed at enhancing the EMA’s support for the development of medicines that target unmet medical needs. It is based on increased interaction and early dialogue with companies developing promising medicines, to optimize their product development plans and speed up their evaluation to help them reach patients earlier. The benefits of a PRIME designation include the appointment of a rapporteur before submission of a marketing authorization application, early dialogue and scientific advice at key development milestones, and the potential to qualify products for accelerated review earlier in the application process. Even if we believe one of our product candidates is eligible for PRIME, the EMA may disagree and instead determine not to make such designation. The EMA PRIME scheme or other schemes, designations, or tools, even if obtained or used for any of our product candidates may not lead to a faster development, regulatory review or approval process compared to therapies considered for approval under conventional procedures and do not assure ultimate approval. In addition, even if one or more of our product candidates is eligible to the PRIME scheme, the EMA may later decide that such product candidates no longer meet the conditions for qualification or decide that the time period for review or approval will not be shortened. Product developers that benefit from PRIME designation may be eligible for accelerated assessment (in 150 days instead of 210 days), which may be granted for medicinal products of major interest from a public health perspective or that target an unmet medical need, but this is not guaranteed. Moreover, in the EU, a “conditional” marketing authorization may be granted in cases where all the required safety and efficacy data are not yet available. A conditional marketing authorization is subject to conditions to be fulfilled for generating missing data or ensuring increased safety measures. A conditional marketing authorization is valid for one year and has to be renewed annually until fulfillment of all relevant conditions. Once the applicable pending studies are provided, a conditional marketing authorization can become a “standard” marketing authorization. However, if the conditions are not fulfilled within the timeframe set by the EMA, the marketing authorization will cease to be renewed. Furthermore, marketing authorizations may also be granted “under exceptional circumstances” when the applicant can show that it is unable to provide comprehensive data on the efficacy and safety under normal conditions of use even after the product has been authorized and subject to the introduction of specific procedures. This may arise when the intended indications are very rare and, in the present state of scientific knowledge, it is not possible to provide comprehensive information, or when generating data may be contrary to generally accepted ethical principles. This type of marketing authorization is close to a conditional marketing authorization as it is reserved to medicinal products to be approved for severe diseases or unmet medical needs and the applicant does not hold the complete data set legally required for the grant of a marketing authorization. However, unlike a conditional marketing authorization, the applicant does not have to provide the missing data and will never have to. Although a marketing authorization “under exceptional circumstances” is granted definitively, the risk-benefit balance of the medicinal product is reviewed annually and the marketing authorization may be withdrawn where the risk-benefit ratio is no longer favorable. The competent regulatory authorities in the EU have broad discretion whether to grant such an accelerated assessment, conditional marketing authorization or marketing authorization under exceptional circumstances, and, even if such assessment or authorization is granted, we may not experience a faster development process, review or authorization compared to conventional procedures. Moreover, the removal or threat of removal of such designation or marketing authorizations may create uncertainty or delay in the clinical development of our product candidates and threaten the commercialization prospects of our product candidates, if approved. Such an occurrence could materially impact our business, financial condition and results of operations. 67 We may conduct certain of or portions of our clinical trials for our product candidates outside of the U.S. and the FDA may not accept data from such trials, in which case our development plans will be delayed, which could materially harm our business. We may in the future choose to conduct one or more of our clinical trials or a portion of our clinical trials for our product candidates outside the U.S. The acceptance of study data from clinical trials conducted outside the U.S. or another jurisdiction by the FDA or comparable foreign regulatory authority may be subject to certain conditions or may not be accepted at all. In cases where data from foreign clinical trials are intended to serve as the sole basis for marketing approval in the U.S., the FDA will generally not approve the application on the basis of foreign data alone unless (i) the data are applicable to the U.S. population and U.S. medical practice; (ii) the trials were performed by clinical investigators of recognized competence and pursuant to GCP regulations; and (iii) the data may be considered valid without the need for an on-site inspection by the FDA, or if the FDA considers such inspection to be necessary, the FDA is able to validate the data through an on-site inspection or other appropriate means. In addition, even where the foreign study data are not intended to serve as the sole basis for approval, the FDA will not accept the data as support for an application for marketing approval unless the study is well-designed and well-conducted in accordance with GCP requirements and the FDA is able to validate the data from the study through an onsite inspection if deemed necessary. Many foreign regulatory authorities have similar approval requirements. In addition, such foreign trials would be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There can be no assurance that the FDA or any comparable foreign regulatory authority will accept data from trials conducted outside of the U.S. or the applicable jurisdiction. If the FDA or any comparable foreign regulatory authority does not accept such data, it would result in the need for additional trials, which could be costly and time- consuming, and which may result in current or future product candidates that we may develop not receiving approval for commercialization in the applicable jurisdiction. Interim, topline and preliminary 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 publicly disclose preliminary or topline data from our clinical studies, which are based on preliminary analyses of then- available data. Such preliminary or topline results and related findings and conclusions are subject to change following more comprehensive reviews of the data related to the particular study or trial. We also make assumptions, estimations, calculations and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. As a result, the preliminary or topline results that we report may differ from future results of the same studies, or different conclusions or considerations may qualify such results once additional data have been received and fully evaluated. Topline data also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, preliminary or topline data should be viewed with caution until the final data are available. From time to time, we may also disclose interim data from our clinical studies. Interim data from this clinical trial and future 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, following more comprehensive reviews of the data, and as more patient data become available. Adverse differences between topline, preliminary or interim data and final data could significantly harm our business prospects. Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses of data from preclinical studies or clinical trials of its product candidates, or may interpret or weigh the importance of data differently, which could impact the value of the particular product candidate, the approvability or prospects for commercialization of the product candidate, or our company in general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is based on what is typically extensive information, and stockholders and others may not agree with what we determine is the material or otherwise appropriate information to include in our disclosure. Information that we decide not to disclose may ultimately be deemed significant with respect to future decisions, conclusions, views, activities or otherwise regarding a particular product, product candidate or our business. If the interim, topline or preliminary data that we disclose differ from actual results, or if others, including regulatory authorities, disagree with the conclusions we reach based on our analyses of such data, our ability to obtain approval for, and commercialize our product 68 candidates may be harmed, which could harm our business, operating results, prospects or financial condition. Any Breakthrough Therapy designation that we may receive from the FDA for our product candidates may not lead to a faster development or regulatory review or approval process, and it does not increase the likelihood that our product candidates will receive marketing approval. We may seek Breakthrough Therapy designation for some of our product candidates, including zilovertamab and ONCT-216. A Breakthrough Therapy is defined as a drug or biologic that is intended, alone or in combination with one or more other drugs or biologics, to treat a serious or life- threatening disease or condition, and preliminary clinical evidence indicates that the drug or biologic may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints. For drugs or biologics that have been designated as Breakthrough Therapies, 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. The designation also includes the same program features as Fast Track designation, including eligibility for rolling review of a submitted NDA or BLA. Designation as a Breakthrough Therapy is within the discretion of the FDA. Accordingly, even if we believe one of our product candidates meets the criteria for designation as a breakthrough therapy, the FDA may disagree and instead determine not to make such designation. In any event, the receipt of a Breakthrough Therapy designation for a product candidate may not result in a faster development process, review or approval compared to drugs considered for approval under conventional FDA procedures and does not assure ultimate approval by the FDA. In addition, even if one or more of our product candidates qualify as Breakthrough Therapies, the FDA may later decide that such product candidates no longer meet the conditions for qualification and rescind the designation. Although we have obtained a rare pediatric disease designation for ONCT-216, there is no guarantee that FDA approval of ONCT-216 will result in a priority review voucher. In 2012, Congress authorized the FDA to award priority review vouchers to sponsors of certain rare pediatric disease product applications. This program is designed to encourage development of new drug and biological products for prevention and treatment of certain rare pediatric diseases. Specifically, under this program, a sponsor who receives an approval for a drug or biologic for a “rare pediatric disease” that meets certain criteria may qualify for a voucher that can be redeemed to receive a priority review of a subsequent marketing application for a different product. The Sponsor of a rare pediatric disease drug product receiving a priority review voucher may transfer (including by sale) the voucher to another sponsor. The voucher may be further transferred any number of times before the voucher is used, as long as the Sponsor making the transfer has not yet submitted the application. The FDA may also revoke any priority review voucher if the rare pediatric disease drug for which the voucher was awarded is not marketed in the U.S. within one year following the date of approval. We have obtained a rare pediatric disease designation for ONCT-216 for the treatment of Ewing’s sarcoma, however, there is no guarantee that we will be able to obtain a priority review voucher, even if ONCT-216 is approved by the FDA. Moreover, Congress included a sunset provision in the statute authorizing the rare pediatric disease priority review voucher program. On December 27, 2020, the Rare Pediatric Disease Priority Review Voucher Program was extended. Under the current statutory sunset provisions, after September 30, 2024, FDA may only award a voucher for an approved rare pediatric disease product application if the Sponsor has rare pediatric disease designation for the drug, and that designation was granted by September 30, 2024. After September 30, 2026, FDA may not award any rare pediatric disease priority review vouchers. 69 Risks Related to Our Reliance on Third Parties We rely on third parties to conduct many of our preclinical studies and clinical trials. Any failure by a third-party to conduct the clinical trials according to GLPs, GCPs and other requirements and in a timely manner may delay or prevent our ability to seek or obtain regulatory approval for or commercialize our product candidates. We are dependent on third parties to conduct our clinical trials and preclinical studies, including our ongoing clinical trials for zilovertamab and ONCT-216 and preclinical studies for our ROR1 cell therapy and DAARI programs. Specifically, we have used and relied on, and intend to continue to use and rely on, medical institutions, clinical investigators, CROs and consultants to conduct our clinical trials in accordance with our clinical protocols and applicable regulatory requirements. These CROs, investigators and other third parties play a significant role in the conduct and timing of these trials and subsequent collection and analysis of data. While we have agreements governing the activities of our third-party contractors, we have limited influence over their actual performance. Nevertheless, we are responsible for ensuring that each of its clinical trials is conducted in accordance with the applicable protocol and legal, regulatory and scientific standards, and our reliance on the CROs and other third parties does not relieve us of our regulatory responsibilities. We and our CROs are required to comply with GCP requirements, which are regulations and guidelines enforced by the FDA and comparable foreign regulatory authorities for all of our product candidates in clinical development. Regulatory authorities enforce these GCPs through periodic inspections of trial sponsors, principal investigators and trial sites. If we or any of our CROs or trial sites fail to comply with applicable GCPs, the clinical data generated in our clinical trials may be deemed unreliable, and the FDA or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. In addition, our clinical trials must be conducted with product produced under cGMP regulations or similar foreign requirements outside the U.S. Our failure to comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process. There is no guarantee that any such CROs, investigators or other third parties will devote adequate time and resources to such trials or perform as contractually required. If any of these third parties fail to meet expected deadlines, adhere to our clinical protocols or meet regulatory requirements, or otherwise performs in a substandard manner, our clinical trials may be extended, delayed or terminated. In addition, many of the third parties with whom we contract may also have relationships with other commercial entities, including our competitors, for whom they may also be conducting clinical trials or other drug development activities that could harm our competitive position. In addition, principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and may receive cash or equity compensation in connection with such services. If these relationships and any related compensation result in perceived or actual conflicts of interest, or the FDA or comparable foreign regulatory authorities conclude that the financial relationship may have affected the interpretation of the study, the integrity of the data generated at the applicable clinical trial site may be questioned and the utility of the clinical trial itself may be jeopardized, which could result in the delay or rejection of any BLA or NDA we submit to the FDA. Similar risks may exist in foreign jurisdictions where we decide to conduct clinical trials. Any such delay or rejection could prevent us from commercializing our product candidates. If any of our relationships with these third parties terminate, we may not be able to enter into arrangements with alternative third parties or do so on commercially reasonable terms. Switching or adding additional CROs, investigators and other third parties involves additional cost and requires management time and focus. In addition, there is a natural transition period when a new CRO commences work. As a result, delays may occur, which can materially impact our ability to meet our desired clinical development timelines. Though we carefully manage our relationships with our CROs, investigators and other third parties, there can be no assurance that we will not encounter challenges or delays in the future or that these delays or challenges will not have a material adverse impact on our business, financial condition and prospects. We rely on third parties for the manufacture of our product candidates for clinical and preclinical development and expect to continue to do so for the foreseeable future. This reliance on third parties increases the risk that we will not have sufficient quantities of our product candidates or products or such quantities at an acceptable cost, which could delay, prevent or impair our development or commercialization efforts. We do not own or operate manufacturing facilities and have no plans to build our own clinical or commercial scale manufacturing capabilities. We rely, and expect to continue to rely, on third parties for the manufacture of our 70 product candidates and related raw materials for clinical and preclinical development, as well as for commercial manufacture if any of our product candidates receive marketing approval. The facilities used by third-party manufacturers to manufacture our product candidates must be approved by the FDA or other regulatory agencies pursuant to inspections that will be conducted after we submit a BLA or an NDA to the FDA or their equivalent to other regulatory agencies. We do not control the manufacturing process of, and are completely dependent on, third-party manufacturers for compliance with cGMP or similar foreign requirements for manufacture of our drug products. If these third-party manufacturers cannot successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or others, including requirements related to the manufacturing of high potency and pure compounds or other products, they will not be able to secure and/or maintain regulatory approval for their manufacturing facilities. In addition, we have no control over the ability of third-party manufacturers to maintain adequate quality control, quality assurance and qualified personnel. If the FDA or a comparable foreign regulatory authority does not approve these facilities for the manufacture of our product candidates, or if regulatory authorities withdraw any such approval in the future, we may need to find alternative manufacturing facilities, which would significantly impact our ability to develop, obtain regulatory approval for or market our product candidates, if approved. Our failure, or the failure of our third-party manufacturers, to comply with applicable regulations could result in sanctions being imposed on us, including clinical holds, fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, seizures or recalls of product candidates or products, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect supplies of our products. Our or a third-party’s failure to execute on our manufacturing requirements, to do so on commercially reasonable terms, or to comply with cGMP or similar foreign requirements could adversely affect our business in a number of ways, including: • • • • • an inability to initiate or continue clinical trials of zilovertamab, ONCT-216 or any future product candidates under development; delay in submitting regulatory applications, or receiving marketing approvals, for our product candidates; subjecting third-party manufacturing facilities to additional inspections by regulatory authorities; requirements to cease development or to recall batches of our product candidates; and in the event of approval to market and commercialize our product candidates, an inability to meet commercial demands for our product candidates. In addition, we may be unable to establish any agreements with third-party manufacturers or to do so on acceptable terms. Even if we are able to establish agreements with third-party manufacturers, reliance on third-party manufacturers entails additional risks, including: • • • • • • failure of third-party manufacturers to comply with regulatory requirements and maintain quality assurance; breach of the manufacturing agreement by the third-party; failure to manufacture our product according to our specifications; failure to manufacture our product according to our schedule, or at all; misappropriation of our proprietary information, including our trade secrets and know-how; and termination or nonrenewal of the agreement by the third-party at a time that is costly or inconvenient for us. Our product candidates and any products that we may develop may compete with other product candidates and products for access to manufacturing facilities. There are a limited number of manufacturers that operate under cGMP or foreign regulations and that might be capable of manufacturing for us. Any performance failure on the part of our existing or future manufacturers could delay clinical development or marketing approval, and any related remedial measures may be costly or time-consuming to implement. We do not currently have arrangements in place for redundant supply or a second source for all required raw materials used in the manufacture of our product candidates. If our current third-party manufacturers cannot perform as agreed, we may be required to replace such manufacturers and we may be unable to replace them on a timely basis or at all. 71 Our current and anticipated future dependence upon others for the manufacture of our product candidates or products may adversely affect our future profit margins and our ability to commercialize any products that receive marketing approval on a timely and competitive basis. Our reliance on third parties requires us to share our trade secrets, which increases the possibility that our trade secrets will be misappropriated or disclosed. Because we currently rely on third parties to manufacture our product candidates and to perform quality testing, we must, at times, share our proprietary technology and confidential information, including trade secrets, with them. We seek to protect our proprietary technology, in part, by entering into confidentiality agreements, consulting agreements or other similar agreements with our advisors, employees, consultants and contractors prior to beginning research or disclosing proprietary information. These agreements typically limit the rights of the third parties to use or disclose our confidential information. Despite the contractual provisions employed when working with third parties, the need to share trade secrets and other confidential information increases the risk that such trade secrets become known by our competitors, are intentionally or inadvertently incorporated into the technology of others or are disclosed or used in violation of these agreements. Given that our proprietary position is based, in part, on our know-how and trade secrets and despite our efforts to protect our trade secrets, a competitor’s discovery of our proprietary technology and confidential information or other unauthorized use or disclosure would impair our competitive position and may have a material adverse effect on our business, financial condition, results of operations and prospects. We have entered into and may seek to enter into additional collaborations, licenses and other similar arrangements, and we may not be successful in doing so, and we may not realize the benefits of such relationships. We may seek to enter into collaborations, joint ventures, licenses and other similar arrangements for the development or commercialization of our product candidates, due to capital costs required to develop or commercialize the product candidate or manufacturing constraints, in addition to our collaboration with Shanghai Pharmaceutical Holding Co., Ltd., SPH USA and Celularity Inc. We may not be successful in our efforts to establish such collaborations for our product candidates because our research and development pipeline may be insufficient, our product candidates may be deemed to be at too early of a stage of development for collaborative effort or third parties may not view our product candidates as having the requisite potential to demonstrate safety and efficacy or significant commercial opportunity. In addition, we face significant competition in seeking appropriate strategic partners, and the negotiation process can be time-consuming and complex. Further, any future collaboration agreements may restrict us from entering into additional agreements with potential collaborators. We cannot be certain that, following a strategic transaction or license, we will achieve an economic benefit that justifies such transaction. Even if we are successful in our efforts to establish such collaborations, the terms that we agree upon may not be favorable to us, and we may not be able to maintain such collaborations if, for example, development or approval of a product candidate is delayed, the safety of a product candidate is questioned or sales of an approved product candidate are unsatisfactory. In April 2018, we entered into a clinical trial and supply agreement with Pharmacyclics in support of our clinical trial to evaluate the combination of zilovertamab with ibrutinib. Ibrutinib is an inhibitor of Bruton’s tyrosine kinase, a key component of cell signaling in B-cells, and is marketed by Pharmacyclics for treatment in patients with CLL and MCL. We initiated a Phase 1/2 clinical trial in May 2018 to assess zilovertamab in combination with ibrutinib in patients with CLL and MCL. Pursuant to the agreement, Pharmacyclics has supplied ibrutinib up to a maximum aggregate amount at no cost to us for part 1 (a dose-finding arm) and part 2 (dose expansion arm) of the ongoing Phase 1/2 clinical trial evaluating zilovertamab in combination with ibrutinib. Under the clinical trial and supply agreement with Pharmacyclics, we are required to provide periodic reports to Pharmacyclics, including safety data reports, and to collaborate with Pharmacyclics in relation to any interactions with regulatory authorities regarding ibrutinib. The agreement includes no upfront costs, milestone or royalty payment commitments. In August 2019, Pharmacyclics agreed to provide additional quantities of ibrutinib at no cost to us for part 3 of the clinical trial, and so that patients who participated in parts 1 and 2 of the study may continue to receive ibrutinib in combination with zilovertamab for as long as their disease is responding. In the event the clinical supply agreement is terminated, we would likely incur substantial additional costs in order to obtain and purchase ibrutinib from a source other than Pharmacyclics and the Phase 2 part 3 of the Phase 1/2 clinical trial may be delayed. In addition, any potential future collaborations may be terminable by our strategic partners, and we may not be able to adequately protect our rights under these agreements. Furthermore, strategic partners may negotiate for certain rights to control decisions regarding the development and commercialization of our product candidates, if 72 approved, and may not conduct those activities in the same manner as we would. Any termination of collaborations we enter into in the future, or any delay in entering into collaborations related to our product candidates, could delay the development and commercialization of our product candidates and reduce their competitiveness if they reach the market, which could have a material adverse effect on our business, financial condition and results of operations. Risks Related to Commercialization of Our Product Candidates Even if we receive regulatory approval for any product candidate, we will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense. Additionally, our product candidates, if approved, could be subject to labeling and other restrictions on marketing or withdrawal from the market, and we may be subject to penalties if we fail to comply with regulatory requirements or if we experience unanticipated problems with our product candidates, when and if any of them are approved. Following potential approval of any of our product candidates, the FDA or comparable foreign regulatory authorities may impose significant restrictions on a product’s indicated uses or marketing or impose ongoing requirements for potentially costly and time-consuming post-approval studies, post-market surveillance or clinical trials to monitor the safety and efficacy of the product. The FDA or comparable foreign regulatory authorities may also require a REMS or similar risk management measures or as a condition of approval of our product candidates, which could include requirements for a medication guide, physician communication plans or additional elements to ensure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. In addition, if the FDA or a comparable foreign regulatory authority approves our product candidates, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion, import, export and recordkeeping for our products will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with cGMPs or similar foreign requirements and GCP requirements for any clinical trials that we conduct post-approval. Later discovery of previously unknown problems with our products, including adverse events of unanticipated type, severity or frequency, or with our 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 our products, withdrawal of the product from the market or voluntary or mandatory product recalls; restrictions on product distribution or use, or requirements to conduct post-marketing studies or clinical trials; fines, restitutions, disgorgement of profits or revenues, warning letters, untitled letters or holds on clinical trials; refusal by the FDA or comparable foreign regulatory authorities to approve pending applications or supplements to approved applications we filed or suspension or revocation of approvals; product seizure or detention, or refusal to permit the import or export of our products; and injunctions or the imposition of civil or criminal penalties. The occurrence of any event or penalty described above may inhibit our ability to commercialize our product candidates and generate revenue and could require us to expend significant time and resources in response and could generate negative publicity. In addition, if any of our product candidates are approved, our product labeling, advertising and promotion will be subject to regulatory requirements and continuing regulatory review. The FDA and comparable foreign regulatory authorities strictly regulate the promotional claims that may be made about drug products. In particular, a product may not be promoted for uses that are not approved by the FDA or comparable foreign regulatory authorities as reflected in the product’s approved labeling. If we receive marketing approval for a product candidate, physicians may nevertheless prescribe it to their patients in a manner that is inconsistent with the approved label. If we are found to have promoted such off-label uses, we may become subject to significant liability. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant sanctions. The federal government has levied large civil and criminal fines against companies for alleged improper promotion and has enjoined several companies from engaging in off-label promotion. The FDA has also requested that companies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed. The FDA and other regulatory authorities’ policies may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. We also cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the U.S. or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may be subject to enforcement action and we may not achieve or sustain profitability. 73 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 products from being developed, approved or commercialized in a timely manner or at all, which could negatively impact our business. The ability of the FDA and comparable foreign regulatory authorities to review and approve new products can be affected by a variety of factors, including government budget and funding levels, statutory, regulatory and policy changes, the FDA’s and comparable foreign regulatory authorities’ ability to hire and retain key personnel and accept the payment of user fees, and other events that may otherwise affect the FDA’s and comparable foreign regulatory authorities’ ability to perform routine functions. Average review times at the FDA and comparable foreign regulatory authorities have fluctuated in recent years as a result. 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, such as the EMA, following its relocation to Amsterdam and resulting staff changes, may also slow the time necessary for new drugs and biologics, or modifications to approved drugs and biologics to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, over the last several years, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA, have had to furlough critical FDA employees and stop critical activities. Separately, in response to the COVID-19 pandemic, in March 2020, the FDA announced its intention to postpone most inspections of foreign manufacturing facilities, and on March 18, 2020, the FDA temporarily postponed routine surveillance inspections of domestic manufacturing facilities. Subsequently, in July 2020, the FDA resumed certain on-site inspections of domestic manufacturing facilities subject to a risk-based prioritization system. The FDA utilized this risk-based assessment system to assist in determining when and where it was safest to conduct prioritized domestic inspections. Additionally, on April 15, 2021, the FDA issued a guidance document in which the FDA described its plans to conduct voluntary remote interactive evaluations of certain drug manufacturing facilities and clinical research sites, among other facilities. According to the guidance, the FDA may request such remote interactive evaluations where the FDA determines that remote evaluation would be appropriate based on mission needs and travel limitations. In May 2021, the FDA outlined a detailed plan to move toward a more consistent state of inspectional operations, and in July 2021, the FDA resumed standard inspectional operations of domestic facilities and was continuing to maintain this level of operation as of September 2021. More recently, the FDA has continued to monitor and implement changes to its inspectional activities to ensure the safety of its employees and those of the firms it regulates as it adapts to the evolving COVID-19 pandemic. Regulatory authorities outside the U.S. have adopted similar restrictions or other policy measures in response to the COVID-19 pandemic. If a prolonged government shutdown occurs, or if global health concerns continue to prevent the FDA or other regulatory authorities from conducting their regular inspections, reviews or other regulatory activities, 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. The commercial success of our product candidates will depend upon the degree of market acceptance of such product candidates by physicians, patients, healthcare payors and others in the medical community. Our product candidates may not be commercially successful. Even if any of our product candidates receive regulatory approval, they may not gain market acceptance among physicians, patients, healthcare payors or the medical community. The commercial success of any of our current or future product candidates will depend significantly on the broad adoption and use of the resulting product by physicians and patients for approved indications. The degree of market acceptance of our products will depend on a number of factors, including: • • • • • • • demonstration of clinical efficacy and safety compared to other more-established products; the indications for which our product candidates are approved; the limitation of our targeted patient population and other limitations or warnings contained in any FDA-approved labeling; acceptance of a new drug for the relevant indication by healthcare providers and their patients; the pricing and cost-effectiveness of our products, as well as the cost of treatment with our products in relation to alternative treatments and therapies; our ability to obtain and maintain sufficient third-party coverage and adequate reimbursement from government healthcare programs, including Medicare and Medicaid, private health insurers and other third-party payors; the willingness of patients to pay all, or a portion of, out-of-pocket costs associated with our products in the absence of sufficient third- party coverage and adequate reimbursement; 74 • • • • • any restrictions on the use of our products, and the prevalence and severity of any adverse effects; potential product liability claims; the timing of market introduction of our products as well as competitive drugs; the effectiveness of our or any of our potential future collaborators’ sales and marketing strategies; and unfavorable publicity relating to the product. If any product candidate is approved but does not achieve an adequate level of acceptance by physicians, hospitals, healthcare payors or patients, we may not generate sufficient revenue from that product and may not become or remain profitable. Our efforts to educate the medical community and third-party payors regarding the benefits of our products may require significant resources and may never be successful. The market opportunities for our product candidates may be limited to patients who are ineligible for or have failed prior treatments and may be small or different from our estimates. Cancer therapies are sometimes characterized as first line, second line or third line, and the FDA often approves new therapies initially only for third line use. When cancer is detected early enough, first line therapy is sometimes adequate to cure the cancer or prolong life without a cure. Whenever first line therapy, including targeted therapy, immunotherapy, chemotherapy, hormone therapy, surgery or a combination of these, proves unsuccessful, second line therapy may be administered. Second line therapies often consist of more chemotherapy, radiation, antibody drugs, tumor targeted small molecules or a combination of these. Third line therapies can include bone marrow transplantation, antibody and small molecule targeted therapies, more invasive forms of surgery and new technologies. In markets with approved therapies, there is no guarantee that our product candidates, even if approved, would be approved for second line or first line therapy. This could limit our potential market opportunity. In addition, we may have to conduct additional clinical trials prior to gaining approval for second line or first line therapy. Our projections of both the number of people who have the cancers we are targeting, as well as the subset of people with these cancers in a position to receive later stage therapy and who have the potential to benefit from treatment with our product candidates, are based on our beliefs and estimates. These estimates have been derived from a variety of sources, including scientific literature, surveys of clinics, patient foundations or market research and may prove to be incorrect. Further, new studies may change the estimated incidence or prevalence of these cancers. The number of patients may turn out to be lower than expected. In addition, the potentially addressable patient population for our product candidates may be limited or may not be amenable to treatment with our product candidates. Even if we obtain significant market share for our product candidates, we may never achieve profitability without obtaining regulatory approval for additional indications, including use as a first- or second-line therapy. Any product candidates for which we intend to seek approval as biologic products may face competition sooner than anticipated. The ACA includes a subtitle called the Biologics Price Competition and Innovation Act of 2009, or 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, an application for a biosimilar product may not be submitted to the FDA until four years following the date that the reference product was first licensed by the FDA. In addition, 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 its product. Similar risks may exist in foreign jurisdictions. We believe that any of our future product candidates approved as a biological product under a BLA should qualify for the 12-year period of exclusivity. However, there is a risk that this exclusivity could be shortened due to Congressional action or otherwise, or that the FDA will not consider our product candidates to be reference products for competing products, potentially creating the opportunity for generic competition sooner than anticipated. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation. Moreover, the extent to which a biosimilar, once approved, could be substituted for any one of our 75 reference products in a way that is similar to traditional generic substitution for non-biological products will depend on a number of marketplace and regulatory factors that are still developing. The FDA and other regulatory agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses. If we are found or alleged to have improperly promoted off-label uses, we may become subject to significant liability. The FDA and other regulatory agencies strictly regulate the promotional claims that may be made about prescription products, as our product candidates would be, if approved. In particular, a product may not be promoted for uses that are not approved by the FDA or such other regulatory agencies as reflected in the product’s approved labeling. If we are found to have promoted such off-label uses, we may become subject to significant liability. The federal government has levied large civil and criminal fines against companies for alleged improper promotion and has enjoined several companies from engaging in off-label promotion. The FDA has also requested that companies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed. If we cannot successfully manage the promotion and avoid off-label promotion of our product candidates, if approved, we could become subject to significant liability, which would materially adversely affect our business and financial condition. The successful commercialization of our product candidates, if approved, will depend in part on the extent to which governmental authorities and health insurers establish coverage, adequate reimbursement levels and favorable pricing policies. Failure to obtain or maintain coverage and adequate reimbursement for our products could limit our ability to market those products and decrease our ability to generate revenue. The availability of coverage and the adequacy of reimbursement by governmental healthcare programs such as Medicare and Medicaid, private health insurers and other third-party payors are essential for most patients to be able to afford prescription medications such as our product candidates, if approved. Our ability to achieve coverage and acceptable levels of reimbursement for our products by third-party payors will have an effect on our ability to successfully commercialize those products. Even if we obtain coverage for a given product by a third-party payor, the resulting reimbursement payment rates may not be adequate or may require co-payments that patients find unacceptably high. We cannot be sure that coverage and reimbursement in the U.S., the European Union or elsewhere will be available for any product that we may develop, and any reimbursement that may become available may be decreased or eliminated in the future. Third-party payors increasingly are challenging prices charged for pharmaceutical products and services, and many third-party payors may refuse to provide coverage and reimbursement for particular drugs when an equivalent generic drug or a less expensive therapy is available. It is possible that a third-party payor may consider our products as substitutable and only offer to reimburse patients for the less expensive product. Even if we are successful in demonstrating improved efficacy or improved convenience of administration with our products, pricing of existing drugs may limit the amount we will be able to charge for our products. These payors may deny or revoke the reimbursement status of a given product or establish prices for new or existing marketed products at levels that are too low to enable us to realize an appropriate return on our investment in product development. If reimbursement is not available or is available only at limited levels, we may not be able to successfully commercialize our products and may not be able to obtain a satisfactory financial return on products that we may develop. There is significant uncertainty related to third-party payor coverage and reimbursement of newly approved products. In the U.S., third-party payors, including private and governmental payors, such as the Medicare and Medicaid programs, play an important role in determining the extent to which new drugs will be covered. Some third-party payors may require pre-approval of coverage for new or innovative devices or drug therapies before they will reimburse healthcare providers who use such therapies. It is difficult to predict at this time what third-party payors will decide with respect to the coverage and reimbursement for our products. Obtaining and maintaining reimbursement status is time consuming, costly and uncertain. The Medicare and Medicaid programs increasingly are used as models for how private payors and other governmental payors develop their coverage and reimbursement policies for drugs. However, no uniform policy for coverage and reimbursement for products exists among third-party payors in the U.S. 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 our products to each payor separately, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained in the first instance. Furthermore, rules and regulations regarding reimbursement change frequently, in some cases at short notice, and we believe that changes in these rules and regulations are likely. 76 Additionally, we or our collaborators may develop companion diagnostic tests for use with our product candidates as we are targeting certain defined populations for our treatments. We, or our collaborators, will be required to obtain coverage and reimbursement for these tests separate and apart from the coverage and reimbursement sought for our product candidates, once approved. While we, or our collaborators, have not yet developed any companion diagnostic test for our product candidates, if we do, there is significant uncertainty regarding our ability to obtain approval, coverage and adequate reimbursement for the same reasons applicable to our product candidates. Outside the U.S., international operations are generally subject to extensive governmental price controls and other market regulations, and we believe the increasing emphasis on cost-containment initiatives in Europe and other countries has and will continue to put pressure on the pricing and usage of our products. In many countries, the prices of medical products are subject to varying price control mechanisms as part of national health systems. Other countries allow companies to fix their own prices for medical products but monitor and control company profits. Additional foreign price controls or other changes in pricing regulation could restrict the amount that we are able to charge for our products. Accordingly, in markets outside the U.S, the reimbursement for our products may be reduced compared with the U.S. and may be insufficient to generate commercially reasonable revenue and profits. Moreover, increasing efforts by governmental and third-party payors in the U.S. and abroad to cap or reduce healthcare costs may cause such organizations to limit both coverage and the level of reimbursement for newly approved products and, as a result, they may not cover or provide adequate payment for our products. We expect to experience pricing pressures in connection with the sale of any of our products due to the trend toward managed healthcare, the increasing influence of health maintenance organizations and additional legislative changes. The downward pressure on healthcare costs in general, particularly prescription drugs and surgical procedures and other treatments, has become very intense. As a result, increasingly high barriers are being erected to the entry of new products. We face significant competition, and if our competitors develop technologies or product candidates more rapidly than we do, or their technologies are more effective, our ability to develop and successfully commercialize products may be adversely affected. The biotechnology and pharmaceutical industries are characterized by rapidly advancing technologies, intense competition and a strong emphasis on proprietary and novel products and product candidates. Our competitors have developed, are developing or may develop products, product candidates and processes competitive with our product candidates. Any product candidates that we successfully develop and commercialize will compete with existing therapies and new therapies that may become available in the future. We believe that a significant number of products are currently under development, and may become commercially available in the future, for the treatment of conditions for which we may attempt to develop product candidates. In particular, there is intense competition in the fields of immunology, inflammation and oncology. Our competitors include larger and better funded pharmaceutical, biopharmaceutical, biotechnological and therapeutics companies. Moreover, we may also compete with universities and other research institutions who may be active in the indications we are targeting and could be in direct competition with us. We also compete with these organizations to recruit management, scientists and clinical development personnel, which could negatively affect our level of expertise and our ability to execute our business plan. We will also face competition in establishing clinical trial sites, enrolling patients for clinical trials and in identifying and in-licensing new product candidates. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. If any of our product candidates are approved in oncology indications such as CLL or MCL, they will compete with small molecule therapies, biologics, cell-based therapies and vaccines, either approved or under development, that are intended to treat the same cancers that we are targeting, including through approaches that may prove to be more effective, have fewer side effects, be less costly to manufacture, be more convenient to administer or have other advantages over any product candidates we develop. In addition to competing with other therapies targeting similar indications, there are numerous other companies and academic institutions focused on similar targets as our product candidates and/or different scientific approaches to treating the same indications. We face competition from such companies in seeking any future potential collaborations to partner our product candidates, as well as potentially competing commercially for any approved products. Significant progress has been made in the treatment of CLL since the advent of targeted therapies and FDA approval of ibrutinib for CLL in 2014. Three classes of targeted therapies have now been approved for the 77 treatment of patients with CLL: inhibitors of BTK a key component of cell signaling in B-cells, such as ibrutinib, which is marketed as Imbruvica by AbbVie, Inc., and Johnson & Johnson, and acalabrutinib, which is marketed as Calquence by AstraZeneca PLC; inhibitors of the protein B-cell lymphoma- 2, or Bcl-2, such as venetoclax, which is marketed as Venclexta and Venclyxto by AbbVie, Inc., and Roche/Genentech; and inhibitors of Phosphoinositide 3-kinase, or PI3K, which include idelalisib, which is marketed as Zydelig by Gilead Sciences, Inc., and duvelisib, which is marketed as Copiktra by Verastem, Inc. These targeted therapies are now the core of the recommended treatment regimens for patients with both first-line and relapsed or refractory CLL, and have achieved objective response rates of 85-90%, two-year PFS of 65-90%, and two-year overall survival of 75-95%. The outcomes are worse for patients with certain prognostic factors, such as 17p or 11q chromosome deletions; for such patients with relapsed or refractory CLL treated with ibrutinib, the reported PFS is 50-75%. While CLL is treatable, it generally remains incurable, and patients with CLL will generally experience a recurrence of their cancer. Additionally, clinicians are investigating their potential in earlier stage disease in multiple clinical trials. There are several therapeutic options available to treat MCL. Newly diagnosed patients are typically treated with rituximab combined with a chemotherapy regimen known as CHOP, comprised of cyclophosphamide, doxorubicin, vincristine, and prednisone. Alternative chemotherapy regimens include bortezomib or bendamustine. Patients with clinical responses to chemotherapy may become candidates for another therapeutic approach, autologous stem cell transplantation, a procedure in which radiation and/or chemotherapy is used to eliminate the patient’s immune cells, including residual MCL cells. Recently, ibrutinib was granted Accelerated Approval by the FDA for the treatment of relapsed MCL. Additionally, two other BTK inhibitors, acalabrutinib (Calquence) and zanubrutinib (Brukinsa) have been approved by the FDA for the treatment of patients with relapsed MCL. These therapies are given continuously for prolonged periods of time, and their use can be associated with significant toxicity. The current standard therapy for patients with localized Ewing sarcoma in the U.S. is a combination of chemotherapy agents, including vincristine, doxorubicin and cyclophosphamide, with alternating cycles of ifosfamide and etoposide – a therapy known as VDC/IE. Patients that respond to this therapy may be candidates for tumor resection and continued treatment for a total of 14 to 17 cycles. This therapeutic regimen, however, is associated with significant toxicities. Patients with metastatic disease are often treated with VDC/IE or variations of this therapy with higher or more compressed dosing. This may also be supplemented by local radiation therapy or systemic radiation followed by autologous hematopoietic stem cell transplant. Many of our competitors have significantly greater financial, technical, manufacturing, marketing, sales and supply resources or experience than we do. If we successfully obtain approval for any product candidate, we will face competition based on many different factors, including the safety and effectiveness of our products, the ease with which our products can be administered and the extent to which patients accept relatively new routes of administration, the timing and scope of regulatory approvals for these products, the availability and cost of manufacturing, marketing and sales capabilities, price, reimbursement coverage and patent position. Competing products could present superior treatment alternatives, including by being more effective, safer, more convenient, less expensive or marketed and sold more effectively than any products we may develop. Competitive products may make any products we develop obsolete or noncompetitive before we recover the expense of developing and commercializing our product candidates. If we are unable to compete effectively, our opportunity to generate revenue from the sale of products we may develop, if approved, could be adversely affected. If the market opportunities for our products are smaller than we believe they are, our revenue may be adversely affected, and our business may suffer. The precise incidence and prevalence for all the conditions we aim to address with our product candidates are unknown. Our projections of both the number of people who have these diseases, the number who have the specific indicated stage or treatment history we believe will be the approved indication, as well as the subset of people with these diseases who have the potential to benefit from treatment with our product candidates, are based on our beliefs and estimates. These estimates have been derived from a variety of sources, including the scientific literature, surveys of clinics, patient foundations or market research, and may prove to be incorrect. Further, new trials may change the estimated incidence or prevalence of these diseases. The total addressable market across all of our product candidates will ultimately depend upon, among other things, the indication approved by regulatory agencies and the diagnostic criteria included in the final label for each of our product candidates approved for sale for these 78 indications, the availability of alternative treatments and the safety, convenience, cost and efficacy of our product candidates relative to such alternative treatments, acceptance by the medical community and patient access, drug pricing and reimbursement. The number of patients in the U.S. and other major markets and elsewhere may turn out to be lower than expected, patients may not be otherwise amenable to treatment with our products or new patients may become increasingly difficult to identify or gain access to, all of which would adversely affect our results of operations and our business. Further, even if we obtain significant market share for our product candidates, because some of our potential target populations are very small, we may never achieve profitability despite obtaining such significant market share. We currently have no marketing and sales organization and have no experience as a company in commercializing products, and we may have to invest significant resources to develop these capabilities. If we are unable to establish marketing and sales capabilities or enter into agreements with third parties to market and sell our products, we may not be able to generate product revenue. We have no internal sales, marketing or distribution capabilities, nor have we commercialized a product. If any of our product candidates ultimately receives regulatory approval, we must build a marketing and sales organization with technical expertise and supporting distribution capabilities to commercialize each such product in major markets, which will be expensive and time consuming, or collaborate with third parties that have sales forces and established distribution systems, either to augment our own sales force and distribution systems or in lieu of our own sales force and distribution systems. We have no prior experience as a company in the marketing, sale and distribution of biopharmaceutical products and there are significant risks involved in building and managing a sales organization, including our ability to hire, retain and incentivize qualified individuals, generate sufficient sales leads, provide adequate training to sales and marketing personnel and effectively manage a geographically dispersed sales and marketing team. Any failure or delay in the development of our internal sales, marketing and distribution capabilities would adversely impact the commercialization of these products. We may not be able to enter into collaborations or hire consultants or external service providers to assist us in sales, marketing and distribution functions on acceptable financial terms, or at all. In addition, our product revenues and our profitability, if any, may be lower if we rely on third parties for these functions than if we were to market, sell and distribute any products that we develop. We likely will have little control over such third parties, and any of them may fail to devote the necessary resources and attention to sell and market our products effectively. If we are not successful in commercializing our products, either on our own or through arrangements with one or more third parties, we may not be able to generate any future product revenue and we would incur significant additional losses. Our future growth may depend, in part, on our ability to operate in foreign markets, where we would be subject to additional regulatory burdens and other risks and uncertainties. Our future growth may depend, in part, on our ability to develop and commercialize our product candidates in foreign markets. We are not permitted to market or promote any of our product candidates before we receive regulatory approval from applicable regulatory authorities in foreign markets, and we may never receive such regulatory approvals for any of our product candidates. To obtain separate regulatory approval in most other countries, we must comply with numerous and varying regulatory requirements regarding safety and efficacy and governing, among other things, clinical trials, commercial sales, manufacturing, pricing and distribution of our product candidates. If we receive regulatory approval of our product candidates and ultimately commercialize our products in foreign markets, we would be subject to additional risks and uncertainties, including: • • • • • • • • • different regulatory requirements for approval of drugs in foreign countries; reduced protection for intellectual property rights; the existence of additional third-party patent rights of potential relevance to our business; unexpected changes in tariffs, trade barriers and regulatory requirements; economic weakness, including inflation, public health emergencies, or political instability in particular foreign economies and markets; compliance with tax, employment, immigration and labor laws for employees living or traveling abroad; foreign currency fluctuations, which could result in increased operating expenses and reduced revenues, and other obligations incident to doing business in another country; foreign reimbursement, pricing and insurance regimes; workforce uncertainty in countries where labor unrest is common; 79 • • production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and business interruptions resulting from geopolitical actions, including war and terrorism, public health emergencies, such as the outbreak of a novel strain of coronavirus affecting the People’s Republic of China and elsewhere or natural disasters including earthquakes, typhoons, floods and fires. Risks Related to Our Business Operations and Industry Our operating results may fluctuate significantly, which makes our future operating results difficult to predict and could cause our operating results to fall below expectations or any guidance we may provide. Our quarterly and annual operating results may fluctuate significantly, which makes it difficult for us to predict our future operating results. These fluctuations may occur due to a variety of factors, many of which are outside of our control, including, but not limited to: • • • • • • • • • the timing and cost of, and level of investment in, research, development, regulatory approval and commercialization activities relating to our product candidates, which may change from time to time; coverage and reimbursement policies with respect to our product candidates, if approved, and potential future drugs that compete with our products; the cost of manufacturing our product candidates, which may vary depending on the quantity of production and any manufacturing issues or challenges requiring additional manufacturing activities, and the terms of our agreements with third-party manufacturers; business interruptions resulting from geopolitical actions, including war and terrorism, or natural disasters such as earthquakes, typhoons, floods and fires or public health emergencies or pandemics such as the recent coronavirus (COVID-19) pandemic; the timing and amount of any milestone or other payments we must make to the licensors and other third parties from whom we have in- licensed or acquired our product candidates; expenditures that we may incur to acquire, develop or commercialize additional product candidates and technologies; the level of demand for any approved products, which may vary significantly; future accounting pronouncements or changes in our accounting policies; and the timing and success or failure of preclinical studies or clinical trials for our product candidates or competing product candidates, or any other change in the competitive landscape of our industry, including consolidation among our competitors or partners. The cumulative effects of these factors could result in large fluctuations and unpredictability in our quarterly and annual operating results. As a result, comparing our operating results on a period-to-period basis may not be meaningful. Investors should not rely on our past results as an indication of our future performance. This variability and unpredictability could also result in our failing to meet the expectations of industry or financial analysts or investors for any period. If our revenue or operating results fall below the expectations of analysts or investors or below any forecasts we may provide to the market, or if the forecasts we provide to the market are below the expectations of analysts or investors, the price of our common stock could decline substantially. Such a stock price decline could occur even when we have met any previously publicly stated revenue or earnings guidance we may provide. We are dependent on the services of our management and if we are not able to retain these individuals or recruit additional management or other key personnel, our business will suffer. Our success depends in part on our continued ability to attract, retain and motivate highly qualified management, clinical and scientific personnel. We are highly dependent upon our senior management, particularly our Chief Executive Officer, as well as other members of our senior management team. The loss of services of any of these individuals could delay or prevent the successful development of our product pipeline, initiation or completion of our planned operations, planned clinical trials or the commercialization of our product candidates. Although we have executed employment agreements or offer letters with each member of our senior management team, these agreements are terminable at will with or without notice and, therefore, we may not be able to retain 80 their services as expected. We do not currently maintain “key person” life insurance on the lives of any of our employees. This lack of insurance means that we may not have adequate compensation for the loss of the services of these individuals. We will need to expand and effectively manage our managerial, operational, financial and other resources in order to successfully pursue our clinical development and commercialization efforts. We may not be successful in maintaining our unique company culture and continuing to attract or retain qualified management and scientific and clinical personnel in the future due to the intense competition for qualified personnel among pharmaceutical, biotechnology and other businesses, particularly in the San Diego area. Our industry has experienced a high rate of turnover of management personnel in recent years. If we are not able to attract, integrate, retain and motivate necessary personnel to accomplish our business objectives, we may experience constraints that will significantly impede the achievement of our development objectives, our ability to raise additional capital and our ability to implement our business strategy. We may encounter difficulties in managing our growth and expanding our operations successfully. As of March 4, 2022, we had twenty-six full-time employees and three part-time employees. As we continue research and development activities and pursue the potential commercialization of our product candidates, as well as function as a public company, we will need to expand our financial, research, development, regulatory, manufacturing, marketing and sales capabilities or contract with third parties to provide these capabilities for the company. As our operations expand, we expect that we will need to manage additional relationships with various strategic partners, suppliers and other third parties. Our future financial performance and our ability to develop and commercialize our product candidates and to compete effectively will depend, in part, on our ability to manage any future growth effectively. We are subject to various foreign, federal, and state healthcare laws and regulations, and our failure to comply with these laws and regulations could harm our results of operations and financial condition. Our business operations and current and future arrangements with investigators, healthcare professionals, consultants, third-party payors and customers expose us to broadly applicable foreign, federal and state fraud and abuse and other healthcare laws and regulations. These laws may constrain the business or financial arrangements and relationships through which we conduct our operations, including how we research, market, sell and distribute any products for which we obtain marketing approval. Such laws include: • • • the federal Anti-Kickback Statute, which prohibits, among other things, persons or entities from knowingly and willfully soliciting, offering, receiving or providing any remuneration (including any kickback, bribe or certain rebates), directly or indirectly, overtly or covertly, in cash or in kind, in return for, either the referral of an individual or the purchase, lease, or order, or arranging for or recommending the purchase, lease, or order of any good, facility, item or service, for which payment may be made, in whole or in part, under a federal healthcare program such as Medicare and Medicaid. A person or entity does not need to have actual knowledge of the federal Anti- Kickback Statute or specific intent to violate it in order to have committed a violation; the federal false claims and civil monetary penalties laws, including the civil False Claims Act, which prohibits, among other things, individuals or entities from knowingly presenting, or causing to be presented, to the federal government, claims for payment or approval that are false or fraudulent, knowingly making, using or causing to be made or used, a false record or statement material to a false or fraudulent claim, or from knowingly making or causing to be made a false statement to avoid, decrease or conceal an obligation to pay money to the federal government. In addition, the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the civil False Claims Act; the Health Insurance Portability and Accountability Act of 1996, or HIPAA, which imposes criminal and civil liability for, among other things, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, or knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false statement, in connection with the delivery of, or payment for, healthcare benefits, items or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation; 81 • • • the federal Physician Payments Sunshine Act, which requires certain 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 the Centers for Medicare and Medicaid Services, CMS, information related to payments and other “transfers of value” made to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors), certain non-physician practitioners (physician assistants, nurse practitioners, clinical nurse specialists, certified registered nurse anesthetists, anesthesiology assistants and certified nurse midwives) and teaching hospitals, as well as ownership and investment interests held by the physicians described above and their immediate family members; federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that potentially harm consumers; and analogous U.S. state and foreign laws and regulations, such as state anti-kickback and false claims laws, which may apply to our business practices, including but not limited to, research, distribution, sales and marketing arrangements and claims involving healthcare items or services reimbursed by non- governmental third-party payors, including private insurers, or by the patients themselves; state laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government, or otherwise restrict payments that may be made to healthcare providers and other potential referral sources; state laws and regulations that require drug manufacturers to file reports relating to pricing and marketing information or which require tracking gifts and other remuneration and items of value provided to physicians, other healthcare providers and entities; and state and local laws that require the registration of pharmaceutical sales representatives. Ensuring that our internal operations and business arrangements with third parties comply with applicable healthcare laws and regulations could involve substantial costs. It is possible that governmental authorities will conclude that our business practices, including our consulting arrangements with physicians and other healthcare providers, some of whom received stock options as compensation for services provided, do not comply with current or future statutes, regulations, agency guidance or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of the laws described above or any other governmental laws and regulations that may apply to us, we may be subject to significant penalties, including civil, criminal and administrative penalties, damages, fines, exclusion from U.S. government funded healthcare programs, such as Medicare and Medicaid, or similar programs in other countries or jurisdictions, disgorgement, individual imprisonment, contractual damages, reputational harm, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, diminished profits and the curtailment or restructuring of our operations. Further, defending against any such actions can be costly, time consuming and may require significant financial and personnel resources. Therefore, even if we are successful in defending against any such actions that may be brought against us, our business may be impaired. If any of the physicians or other providers or entities with whom we expect to do business are found to not be in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusion from government funded healthcare programs and imprisonment. If any of the above occur, it could adversely affect our ability to operate our business and our results of operations. Recently enacted legislation, future legislation and healthcare reform measures may increase the difficulty and cost for us to obtain marketing approval for and commercialize our product candidates and may affect the prices we may set. In the U.S. and some foreign jurisdictions, there have been, and we expect there will continue to be, a number of legislative and regulatory changes to the healthcare system, including cost-containment measures that may reduce or limit coverage and reimbursement for newly approved drugs and affect our ability to profitably sell any product candidates for which we obtain marketing approval. In particular, there have been and continue to be a number of initiatives at the U.S. federal and state levels that seek to reduce healthcare costs and improve the quality of healthcare. 82 For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, referred to collectively as the ACA, was enacted in the U.S. Among the provisions of the ACA of importance to our potential product candidates, the ACA: established an annual, nondeductible fee on any entity that manufactures or imports specified branded prescription drugs and biologic agents; extended manufacturers’ Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed care organizations; expands eligibility criteria for Medicaid programs; expanded the entities eligible for discounts under the Public Health program; increased the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program; created a new Medicare Part D coverage gap discount program; establishes a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in and conduct comparative clinical effectiveness research, along with funding for such research; and established a Center for Medicare Innovation at CMS to test innovative payment and service delivery models to lower Medicare and Medicaid spending. Since its enactment, there have been judicial, executive and Congressional challenges to certain aspects of the ACA. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA. Thus, the ACA will remain in effect in its current form. Further, prior to the U.S. Supreme Court ruling, President Biden issued an executive order that initiated a special enrollment period for purposes of obtaining health insurance coverage through the ACA marketplace from February 15, 2021 through August 15, 2021. The executive order instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. In addition, other legislative changes have been proposed and adopted since the ACA was enacted. On August 2, 2011, the Budget Control Act of 2011 was signed into law, which, among other things, resulted in reductions to Medicare payments to providers of 2% per fiscal year, which went into effect on April 1, 2013 and, due to subsequent legislative amendments to the statute, will remain in effect through 2030, with the exception of a temporary suspension from May 1, 2020 through March 31, 2022, unless additional Congressional action is taken. On January 2, 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, reduced Medicare payments to several providers, including hospitals, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. Further, there has been heightened governmental scrutiny in the U.S. of pharmaceutical pricing practices in light of the rising cost of prescription drugs. Such scrutiny has resulted in several recent congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for products. At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. Legally mandated price controls on payment amounts by third-party payors or other restrictions could harm our business, results of operations, financial condition and prospects. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs. This could reduce the ultimate demand for our product candidates, if approved, or put pressure on our product pricing, which could negatively affect our business, results of operations, financial condition and prospects. Additionally, on May 30, 2018, the Trickett Wendler, Frank Mongiello, Jordan McLinn, and Matthew Bellina Right to Try Act of 2017, or the Right to Try Act, was signed into law. The law, among other things, provides a federal framework for certain patients with life-threatening diseases or conditions 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. There is no obligation for a drug manufacturer to make our drug products available to eligible patients as a result of the Right to Try Act. 83 We expect that the ACA, these new laws and other healthcare reform measures that may be adopted in the future may result in additional reductions in Medicare and other healthcare funding, more rigorous coverage criteria, new payment methodologies and additional downward pressure on the price that we receive for any approved product. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability or commercialize our product candidates, if approved. Actual or perceived failures to comply with applicable data protection, privacy and security laws, regulations, standards and other requirements could adversely affect our business, results of operations, and financial condition. The global data protection landscape is rapidly evolving, and we are or may become subject to numerous state, federal and foreign laws, requirements and regulations governing the collection, use, disclosure, retention, and security of personal data, such as information that we may collect in connection with clinical trials in the U.S. and abroad. Implementation standards and enforcement practices are likely to remain uncertain for the foreseeable future, and we cannot yet determine the impact future laws, regulations, standards, or perception of their requirements may have on our business. This evolution may create uncertainty in our business, affect our ability to operate in certain jurisdictions or to collect, store, transfer use and share personal information, necessitate the acceptance of more onerous obligations in our contracts, result in liability or impose additional costs on us. The cost of compliance with these laws, regulations and standards is high and is likely to increase in the future. Any failure or perceived failure by us to comply with federal, state or foreign laws or regulation, our internal policies and procedures or our contracts governing our processing of personal information could result in negative publicity, government investigations and enforcement actions, claims by third parties and damage to our reputation, any of which could have a material adverse effect on our operations, financial performance and business. As our operations and business grow, we may become subject to or affected by new or additional data protection laws and regulations and face increased scrutiny or attention from regulatory authorities. In the U.S., HIPAA imposes, among other things, certain standards relating to the privacy, security, transmission and breach reporting of individually identifiable health information. Most healthcare providers, including research institutions from which we obtain patient health information, are subject to privacy and security regulations promulgated under HIPAA, as amended. Any person may be prosecuted under HIPAA’s criminal provisions either directly or under aiding-and-abetting or conspiracy principles. Consequently, depending on the facts and circumstances, we could face substantial criminal penalties if we knowingly receive individually identifiable health information from a HIPAA-covered healthcare provider or research institution that has not satisfied HIPAA’s requirements for disclosure of individually identifiable health information. In addition, we may maintain sensitive health-related or other personal information, that we receive throughout the clinical trial process, in the course of our research collaborations, and directly from individuals (or their healthcare providers) who enroll in our patient assistance programs. As such, we may be subject to state laws requiring notification of affected individuals and state regulators in the event of a breach of personal information, which is a broader class of information than the health information protected by HIPAA. Certain states have also adopted comparable privacy and security laws and regulations, some of which may be more stringent than HIPAA. Such laws and regulations will be subject to interpretation by various courts and other governmental authorities, thus creating potentially complex compliance issues for us and our future customers and strategic partners. In addition, the California Consumer Privacy Act, or CCPA, went into effect on January 1, 2020. The CCPA creates individual privacy rights for California consumers and increases the privacy and security obligations of entities handling certain personal information. The CCPA provides for civil penalties for violations, as well as a private right of action for data breaches that is expected to increase data breach litigation. The CCPA may increase our compliance costs and potential liability, and many similar laws have been proposed at the federal level and in other states. Further, the California Privacy Rights Act, or CPRA, was recently voted into law by California residents. The CPRA significantly amends the CCPA, and imposes additional data protection obligations on covered companies doing business in California, including additional consumer rights processes and opt outs for certain uses of sensitive data. It also creates a new California data protection agency specifically tasked to enforce the law, which would likely result in increased regulatory scrutiny of California businesses in the areas of data 84 protection and security. The substantive requirements for businesses subject to the CPRA will go into effect on January 1, 2023, and become enforceable on July 1, 2023. In the EU, the GDPR went into effect in May 2018 and imposes strict requirements for processing the personal data of individuals within the European Economic Area, or EEA. Companies that must comply with the GDPR face increased compliance obligations and risk, including more robust regulatory enforcement of data protection requirements and potential fines for noncompliance of up to €20 million or 4% of the annual global revenues of the noncompliant company, whichever is greater. Among other requirements, the GDPR regulates transfers of personal data subject to the GDPR to third countries that have not been found to provide adequate protection to such personal data, including the U.S., and the efficacy and longevity of current transfer mechanisms between the EU and the U.S. remains uncertain. For example, Court of Justice of the EU, or the CJEU, limited how organizations could lawfully transfer personal data from the EEA, to the U.S. by invalidating an agreed upon framework for data transferred from the EU to the U.S., called the Privacy Shield, for purposes of international transfers and imposing further restrictions on the use of the standard contractual clauses. To the extent we are unable to transfer personal data between and among regions in which we operate or intend to operate as a result of regulatory authorities issuing further guidance on personal data export mechanisms, including circumstances where the standard contractual clauses cannot be used, and/or start taking enforcement action, it could affect the manner in which we operate and could adversely affect our financial results. Further, since January 1, 2021, companies have had to comply with the GDPR and also the UK GDPR, which, together with the amended UK Data Protection Act 2018, retains the GDPR in UK national law. The UK GDPR mirrors the fines under the GDPR, i.e., fines up to the greater of €20 million (£17.5 million) or 4% of global turnover. The relationship between the UK and the EU in relation to certain aspects of data protection law remains unclear, and it is unclear how UK data protection laws and regulations will develop in the medium to longer term, and how data transfers to and from the UK will be regulated in the long term. The European Commission has adopted an adequacy decision in favor of the UK, enabling data transfers from EU member states to the UK without additional safeguards. However, the UK adequacy decision will automatically expire in June 2025 unless the European Commission re-assesses and renews or/ extends that decision. and remains under review by the Commission during this period. In September 2021, the UK government launched a consultation on its proposals for wide-ranging reform of UK data protection laws following Brexit. There is a risk that any material changes which are made to the UK data protection regime could result in the European Commission reviewing the UK adequacy decision, and the UK losing its adequacy decision if the European Commission deems the UK to no longer provide adequate protection for personal data. The relationship between the UK and the EU in relation to certain aspects of data protection law remains uncertain, and it is unclear how UK data protection laws and regulations will develop in the medium to longer term. Although we work to comply with applicable laws, regulations and standards, our contractual obligations and other legal obligations, these requirements are evolving and may be modified, interpreted and applied in an inconsistent manner from one jurisdiction to another, and may conflict with one another or other legal obligations with which we must comply. If we or our third-party CROs or other contractors or consultants fail to comply with applicable federal, state or local regulatory requirements, we could be subject to a range of regulatory actions that could affect our or our contractors’ ability to develop and commercialize our product candidates and could harm or prevent sales of any affected products that we are able to commercialize, or could substantially increase the costs and expenses of developing, commercializing and marketing our products. Any threatened or actual government enforcement action could also generate adverse publicity and require that we devote substantial resources that could otherwise be used in other aspects of our business. Increasing use of social media could give rise to liability, breaches of data security or reputational damage. We and any of our third-party manufacturers or suppliers may use potent chemical agents and hazardous materials, and any claims relating to improper handling, storage or disposal of these materials could be time consuming or costly. We and any of our third-party manufacturers or suppliers will use biological materials, potent chemical agents and may use hazardous materials, including chemicals and biological agents and compounds that could be dangerous to human health and safety of the environment. Our historical operations and the operations of our third-party manufacturers and suppliers also produce hazardous waste products. Federal, state and local laws and regulations govern the use, generation, manufacture, storage, handling and disposal of these materials and wastes. 85 Compliance with applicable environmental laws and regulations may be expensive, and current or future environmental laws and regulations may impair our product development efforts. In addition, we cannot eliminate the risk of accidental injury or contamination from these materials or wastes. We do not carry specific biological or hazardous waste insurance coverage, and our property, casualty and general liability insurance policies specifically exclude coverage for damages and fines arising from biological or hazardous waste exposure or contamination. In the event of contamination or injury, we could be held liable for damages or be penalized with fines in an amount exceeding our resources, and our clinical trials or regulatory approvals could be suspended. Although we maintain workers’ compensation insurance for certain costs and expenses we may incur due to injuries to our employees resulting from the use of hazardous materials or other work-related injuries, this insurance may not provide adequate coverage against potential liabilities. We do not maintain insurance for toxic tort claims that may be asserted against us in connection with our storage or disposal of biologic, hazardous or radioactive materials. In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations, which have tended to become more stringent over time. These current or future laws and regulations may impair our research, development or production efforts. Failure to comply with these laws and regulations also may result in substantial fines, penalties or other sanctions or liabilities, which could materially adversely affect our business, financial condition, results of operations and prospects. If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of our products. We face an inherent risk of product liability as a result of the clinical trials of our product candidates and will face an even greater risk if we commercialize our product candidates. For example, we may be sued if our product candidates allegedly cause injury or are found to be otherwise unsuitable during product testing, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product candidate, negligence, strict liability and a breach of warranties. Claims may be brought against us by clinical trial participants, patients or others using, administering or selling products that may be approved in the future. Claims could also be asserted under state consumer protection acts. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit or cease the commercialization of our products. Even a successful defense would require significant financial and management resources. Regardless of the merits or eventual outcome, liability claims may result in: • • • • • • • • • • decreased demand for our products; injury to our reputation and significant negative media attention; withdrawal of clinical trial participants; costs to defend the related litigation; a diversion of management’s time and our resources; substantial monetary awards to trial participants or patients; product recalls, withdrawals or labeling, marketing or promotional restrictions; significant negative financial impact; the inability to commercialize our product candidates; and a decline in our stock price. We currently hold $10.0 million in product liability insurance coverage in the aggregate. We may need to increase our insurance coverage as we expand our clinical trials or if we commence commercialization of our product candidates. Insurance coverage is increasingly expensive. Our inability to obtain and retain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or inhibit the commercialization of our product candidates. Although we maintain such insurance, any claim that may be brought against us could result in a court judgment or settlement in an amount that is not covered, in whole or in part, by our insurance or that is in excess of the limits of our insurance coverage. Our insurance policies will also have various exclusions, and we may be subject to a product liability claim for which we have no coverage. We may have to pay any amounts awarded by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered by our insurance, and we may not have, or be able to obtain, sufficient capital to pay such amounts. 86 We and any of our potential future collaborators will be required to report to regulatory authorities if any of our approved products cause or contribute to adverse medical events, and any failure to do so would result in sanctions that would materially harm our business. If we and any of our potential future collaborators are successful in commercializing our products, the FDA and foreign regulatory authorities would require that we and any of our potential future collaborators report certain information about adverse medical events if those products may have caused or contributed to those adverse events. The timing of our obligation to report would be triggered by the date we become aware of the adverse event as well as the nature of the event. We and any of our potential future collaborators or CROs may fail to report adverse events within the prescribed timeframe. If we or any of our potential future collaborators or CROs fail to comply with such reporting obligations, the FDA or a foreign regulatory authority could take action, including criminal prosecution, the imposition of civil monetary penalties, seizure of our products or delay in approval or clearance of future products. Our internal computer systems, or those of any of our CROs, manufacturers, other contractors or consultants or potential future collaborators, may fail or suffer security breaches, which could result in a material disruption of our product development programs. U.S. federal and various state and foreign governments have adopted or proposed requirements regarding the collection, distribution, use, security, and storage of health-related and other personal information, and federal and state consumer protection laws are being applied to enforce regulations related to the online collection, use, and dissemination of data. Despite the implementation of security measures, our internal computer systems and those of our current and any future CROs and other contractors, consultants and collaborators are vulnerable to damage from computer viruses, cybersecurity threats, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. Attacks upon information technology systems are increasing in their frequency, levels of persistence, sophistication and intensity, and are being conducted by sophisticated and organized groups and individuals with a wide range of motives and expertise. As a result of the COVID-19 pandemic, we may also face increased cybersecurity risks due to our reliance on internet technology and the number of our employees who are working remotely, which may create additional opportunities for cybercriminals to exploit vulnerabilities. Furthermore, because the techniques used to obtain unauthorized access to, or to sabotage, systems change frequently and often are not recognized until launched against a target, we may be unable to anticipate these techniques or implement adequate preventative measures. We may also experience security breaches that may remain undetected for an extended period. If such an event were to occur and cause interruptions in our operations or result in the unauthorized disclosure of or access to personal or other confidential information, it could result in a material disruption of our development programs and our business operations, whether due to a loss of our trade secrets or other similar disruptions. Some of the federal, state and foreign government requirements include obligations of companies to notify individuals of security breaches involving particular personal information, which could result from breaches experienced by us or by our vendors, contractors, or organizations with which we have formed strategic relationships. Even though we may have contractual protections with such vendors, contractors, or other organizations, notifications and follow-up actions related to a security breach could impact our reputation, cause us to incur significant costs, including legal expenses, harm customer confidence, hurt our expansion into new markets, cause us to incur remediation costs, or cause us to lose existing customers. For example, 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. We also rely on third parties to manufacture our product candidates, and similar events relating to their computer systems could also have a material adverse effect on our business. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability, the further development and commercialization of our product candidates could be delayed, and we could be subject to significant fines, penalties or liabilities for any noncompliance to certain privacy and security laws. Business disruptions could seriously harm our future revenue and financial condition and increase our costs and expenses. Our operations could be subject to earthquakes, power shortages, telecommunications failures, water shortages, floods, hurricanes, typhoons, fires, extreme weather conditions, medical epidemics and other natural or manmade disasters or business interruptions, for which we are predominantly self- insured. We rely on third- party manufacturers to produce our product candidates. Our ability to obtain clinical supplies of our product candidates could be disrupted if the operations of these suppliers were affected by a man-made or natural disaster or other business interruption. In addition, our corporate headquarters is located in San Diego, California near major earthquake faults and fire zones, and the ultimate impact on us of being located near major earthquake faults and fire zones and being consolidated in a certain geographical area is unknown. The occurrence of any of these business disruptions could seriously harm our operations and financial condition and increase our costs and expenses. 87 Our employees and independent contractors, including principal investigators, CROs, consultants and vendors, may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements. We are exposed to the risk that our employees and independent contractors, including principal investigators, CROs, consultants and vendors may engage in misconduct or other illegal activity. Misconduct by these parties could include intentional, reckless and/or negligent conduct or disclosure of unauthorized activities to us that violate: (1) the laws and regulations of the FDA and other similar regulatory requirements, including those laws that require the reporting of true, complete and accurate information to such authorities, (2) manufacturing standards, including cGMP and similar foreign requirements, (3) federal, state and foreign data privacy, security, fraud and abuse and other healthcare laws and regulations in the U.S. and abroad or (4) laws that require the true, complete and accurate reporting of financial information or data. Activities subject to these laws also involve the improper use or misrepresentation of information obtained in the course of clinical trials, the creation of fraudulent data in our preclinical studies or clinical trials, or illegal misappropriation of drug product, which could result in regulatory sanctions and cause serious harm to our reputation. It is not always possible to identify and deter misconduct by employees and other third parties, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. In addition, we are subject to the risk that a person or government could allege such fraud or other misconduct, even if none occurred. 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 and financial results, including, without limitation, the imposition of significant civil, criminal and administrative penalties, damages, monetary fines, disgorgements, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, individual imprisonment, contractual damages, reputational harm, diminished profits and future earnings, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, and curtailment of our operations, any of which could adversely affect our ability to operate our business and our results of operations. 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 could face criminal liability and other serious consequences for violations, which could 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, and various economic and trade sanctions regulations administered by the U.S. Treasury Department’s Office of Foreign Assets Controls, and anti- corruption and anti-money laundering laws and regulations, including 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, 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, clinical research organizations, contractors and other collaborators and partners from authorizing, promising, offering, providing, soliciting or receiving, directly or indirectly, improper payments or anything else of value to recipients in the public or private sector. We may engage third parties for clinical trials outside of the U.S., to sell our products abroad once we enter a commercialization phase, and/or to obtain necessary permits, licenses, patent registrations and other regulatory approvals. We 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, clinical research organizations, contractors and other collaborators and partners, even if we do not explicitly authorize or have actual knowledge of such activities. Any violations 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. We may engage in strategic transactions that could impact our liquidity, increase our expenses and present significant distractions to our management. From time to time, we may consider strategic transactions, such as acquisitions of companies, asset purchases and out-licensing or in-licensing of intellectual property, products or technologies, similar to our approach in in-licensing and acquiring our current product candidates. Any future transactions could increase our near and long- 88 term expenditures, result in potentially dilutive issuances of our equity securities, including our common stock, or the incurrence of debt, contingent liabilities, amortization expenses or acquired in-process research and development expenses, any of which could affect our financial condition, liquidity and results of operations. Additional potential transactions that we may consider in the future include a variety of business arrangements, including spin- offs, strategic partnerships, joint ventures, restructurings, divestitures, business combinations and investments. Future acquisitions may also require us to obtain additional financing, which may not be available on favorable terms or at all. These transactions may never be successful and may require significant time and attention of management. In addition, the integration of any business that we may acquire in the future may disrupt our existing business and may be a complex, risky and costly endeavor for which we may never realize the full benefits of the acquisition. Accordingly, although there can be no assurance that we will undertake or successfully complete any additional transactions of the nature described above, any additional transactions that we do complete could have a material adverse effect on our business, results of operations, financial condition and prospects. Risks Related to Our Intellectual Property Our success depends on our ability to protect our intellectual property and our proprietary technologies. Our commercial success depends in part on our ability to obtain and maintain patent protection and trade secret protection for our product candidates, proprietary technologies and their uses as well as our ability to operate without infringing upon the proprietary rights of others. If we are unable to protect our intellectual property rights or if our intellectual property rights are inadequate for our technology or our product candidates, our competitive position could be harmed. We generally seek to protect our proprietary position by licensing or filing patent applications in the U.S. and abroad related to our product candidates, proprietary technologies and their uses that are important to our business. Our or our licensor’s 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. There can be no assurance that our or our licensor’s patent applications will result in patents being issued or that issued patents will afford sufficient protection against competitors with similar technology, nor can there be any assurance that the patents if issued will not be infringed, designed around or invalidated by third parties. Even issued patents may later be found invalid or unenforceable or may be modified or revoked in proceedings instituted by third parties before various patent offices or in courts. The degree of future protection for our proprietary rights is uncertain. Only limited protection may be available and may not adequately protect our rights or permit us to gain or keep any competitive advantage. These uncertainties and/or limitations in our ability to properly protect the intellectual property rights relating to our product candidates could have a material adverse effect on our financial condition and results of operations. Although we own and license issued patents in the U.S. and foreign countries, we cannot be certain that the claims in our or our licensor’s other U.S. pending patent applications, corresponding international patent applications and patent applications in certain foreign countries will be considered patentable by the U.S. Patent and Trademark Office, or USPTO, courts in the U.S. or by the patent offices and courts in foreign countries, nor can we be certain that the claims in our or our licensor’s issued patents will not be found invalid or unenforceable if challenged. The patent application process is subject to numerous risks and uncertainties, and there can be no assurance that we, our licensors or any of our potential future collaborators will be successful in protecting our product candidates by obtaining and defending patents. These risks and uncertainties include the following: • • • • the USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other provisions during the patent process, the noncompliance with which can result in abandonment or lapse of a patent or patent application, and partial or complete loss of patent rights in the relevant jurisdiction; patent applications may not result in any patents being issued; patents may be challenged, invalidated, modified, revoked, circumvented, found to be unenforceable or otherwise may not provide any competitive advantage; our competitors, many of whom have substantially greater resources than we do and many of whom have made significant investments in competing technologies, may seek or may have already obtained patents that will limit, interfere with or block our ability to make, use and sell our product candidates; 89 • • there may be significant pressure on the U.S. government and international governmental bodies to limit the scope of patent protection both inside and outside the U.S. for disease treatments that prove successful, as a matter of public policy regarding worldwide health concerns; and countries other than the U.S. may have patent laws less favorable to patentees than those upheld by U.S. courts, allowing foreign competitors a better opportunity to create, develop and market competing products. The patent prosecution process is also expensive and time consuming, and we and our licensors 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 or our licensors 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 do not have the right to control the preparation, filing and prosecution of patent applications, or to maintain the patents, directed to technology that we license from third parties. We may also require the cooperation of our licensor in order to enforce the licensed patent rights, and such cooperation may not be provided. Therefore, these patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. We cannot be certain that patent prosecution and maintenance activities by our licensors have been or will be conducted in compliance with applicable laws and regulations, which may affect the validity and enforceability of such patents or any patents that may issue from such applications. If they fail to do so, this could cause us to lose rights in any applicable intellectual property that we in- license, and as a result our ability to develop and commercialize products or product candidates may be adversely affected and we may be unable to prevent competitors from making, using and selling competing products. In addition, although we enter into non-disclosure and confidentiality agreements with parties who have access to patentable aspects of our research and development output, such as our employees, outside scientific collaborators, CROs, third-party manufacturers, consultants, advisors, licensees, collaboration partners, and other third parties, any of these parties may breach such agreements and disclose such output before a patent application is filed, thereby jeopardizing our ability to seek patent protection. If we fail to comply with our obligations in the agreements under which we license intellectual property rights from third parties, including with respect to zilovertamab and ONCT-216, or otherwise experiences disruptions in our business relationships with our licensors, we could lose license rights that are important to our business. We are a party to several license agreements under which we are granted rights to intellectual property that are important to our business and we may enter into additional license agreements in the future. For example, in March 2014, we entered into an exclusive license agreement with Georgetown University, or Georgetown, to obtain an exclusive license to certain intellectual property rights to develop and commercialize compounds targeting EWS- FLI1. In March 2016, we entered into an exclusive license agreement with the Regents of the University of California to obtain an exclusive license to certain intellectual property rights to develop and commercialize zilovertamab and other ROR1 related naked antibodies. We are also party to a license agreement with the University of Tennessee Research Foundation pursuant to which we have exclusive rights to certain intellectual property rights to develop and commercialize product candidates in our DAARI program. These license agreements impose, and we expect that any future license agreements where we in-license intellectual property, will impose on us, various development, regulatory and/or commercial diligence obligations, payment of milestones and/or royalties and other obligations. If we fail to comply with our obligations under these agreements, or we are subject to bankruptcy-related proceedings, the licensor may have the right to terminate the license, in which event we would not be able to market products covered by the license. 90 We may need to obtain licenses from third parties to advance our research or allow commercialization of our product candidates, and we cannot provide any assurances that third-party patents do not exist which might be enforced against our product candidates in the absence of such a license. We may fail to obtain any of these licenses on commercially reasonable terms, if at all. Even if we are able to obtain a license, it may be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. In that event, we may be required to expend significant time and resources to develop or license replacement technology. If we are unable to do so, we may be unable to develop or commercialize the affected product candidates, which could materially harm our business and the third parties owning such intellectual property rights could seek either an injunction prohibiting our sales, or, with respect to our sales, an obligation on our part to pay royalties and/or other forms of compensation. Licensing of intellectual property is of critical importance to our business and involves complex legal, business and scientific issues. Disputes may arise between us and our licensors regarding intellectual property subject to a license agreement, including: • • • • • • the scope of rights granted under the license agreement and other interpretation-related issues; whether and the extent to which our technology and processes infringe on intellectual property of the licensor that is not subject to the licensing agreement; our right to sublicense patents and other rights to third parties; our diligence obligations with respect to the use of the licensed technology in relation to our development and commercialization of our product candidates, and what activities satisfy those diligence obligations; our right to transfer or assign the license; and the ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and us and our partners. If disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on acceptable terms, we may not be able to successfully develop and commercialize the affected product candidates, which would have a material adverse effect on our business. If the scope of any patent protection we obtain is not sufficiently broad, or if we lose any of our patent protection, our ability to prevent our competitors from commercializing similar or identical product candidates would be adversely affected. The patent position of biopharmaceutical companies generally is highly uncertain, involves complex legal and factual questions, and has been the subject of much litigation in recent years. As a result, the issuance, scope, validity, enforceability and commercial value of our and our licensor’s patent rights are highly uncertain. Our and our licensor’s pending and future patent applications may not result in patents being issued which protect our product candidates or which effectively prevent others from commercializing competitive product candidates. Moreover, the coverage claimed in a patent application can be significantly reduced before the patent is issued, and its scope can be reinterpreted after issuance. Even if patent applications we own or license currently or in the future issue as patents, they may not issue in a form that will provide us with any meaningful protection, prevent competitors or other third parties from competing with us, or otherwise provide us with any competitive advantage. Any patents that we own or license may be challenged or circumvented by third parties or may be narrowed or invalidated as a result of challenges by third parties. Consequently, we do not know whether our product candidates will be protectable or remain protected by valid and enforceable patents. Our competitors or other third parties may be able to circumvent our or our licensor’s patents by developing similar or alternative technologies or products in a non-infringing manner which could materially adversely affect our business, financial condition, results of operations and prospects. The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our and our licensor’s patents may not cover our product candidates or may be challenged in the courts or patent offices in the U.S. and abroad. Our and our licensor’s patents may be subject to a third- party pre-issuance submission of prior art to the USPTO, or become involved in opposition, derivation, revocation, reexamination, post-grant review, or PGR, and inter partes review, or IPR, or other similar proceedings in the USPTO or foreign patent offices challenging our or our licensor’s patent rights. The outcome following legal assertions of invalidity and unenforceability is unpredictable. With respect to the validity question, for example, we cannot be certain that there is no invalidating prior art, of which we or our predecessors or our licensor and the patent examiner were unaware during prosecution. There is no assurance that all potentially relevant prior art relating to our patents and patent applications or those of our licensors has been found. There is also no assurance that there is not prior art of which 91 we, our predecessors or licensors are aware, but which we do not believe affects the validity or enforceability of a claim in our patents and patent applications or those of our licensors, which may, nonetheless, ultimately be found to affect the validity or enforceability of a claim. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate or render unenforceable, our or our licensor’s patent rights, allow third parties to commercialize our product candidates and compete directly with us, without payment to us. Such loss of patent rights, loss of exclusivity or in patent claims being narrowed, invalidated or held unenforceable could limit our ability to stop others from using or commercializing similar or identical technology and products, or limit the duration of the patent protection of our product candidates. Such proceedings also may result in substantial cost and require significant time from our scientists and management, even if the eventual outcome is favorable to us. In addition, if the breadth or strength of protection provided by our or our licensor’s patents and patent applications is threatened, regardless of the outcome, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates. The patent protection and patent prosecution for some of our product candidates may be dependent on third parties. We or our licensors may fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent protection on them. Therefore, we or our licensors may miss potential opportunities to strengthen our patent position. It is possible that defects of form in the preparation or filing of our or our licensor’s patents or patent applications may exist, or may arise in the future, for example with respect to proper priority claims, inventorship, claim scope, or requests for patent term adjustments. If there are material defects in the form, preparation, prosecution, or enforcement of our or our licensor’s patents or patent applications, such patents may be invalid and/or unenforceable, and such applications may never result in valid, enforceable patents. If we or our licensors, whether current or future, fail to establish, maintain or protect our patents and other intellectual property rights, such rights may be reduced or eliminated. If our licensors are not fully cooperative or disagree with us as to the prosecution, maintenance or enforcement of any patent rights, such patent rights could be compromised. Any of these outcomes could impair our ability to prevent competition from third parties, which may have an adverse impact on our business. As a licensee of third parties, we rely on third parties to file and prosecute patent applications and maintain patents and otherwise protect the licensed intellectual property under some of our license agreements. We have not had and do not have primary control over these activities for certain of our patents or patent applications and other intellectual property rights. We cannot be certain that such activities by third parties have been or will be conducted in compliance with applicable laws and regulations or will result in valid and enforceable patents or other intellectual property rights. Pursuant to the terms of the license agreements with some of our licensors, the licensors may have the right to control enforcement of our licensed patents or defense of any claims asserting the invalidity of these patents and even if we are permitted to pursue such enforcement or defense, we will require the cooperation of our licensors. We cannot be certain that our licensors will allocate sufficient resources or prioritize their or our enforcement of such patents or defense of such claims to protect our interests in the licensed patents. Even if we are not a party to these legal actions, an adverse outcome could harm our business because it might prevent us from continuing to license intellectual property that we may need to operate our business. If any of our licensors or any of our future licensors or future collaborators fail to appropriately prosecute and maintain patent protection for patents covering any of our product candidates, our ability to develop and commercialize those product candidates may be adversely affected and we may not be able to prevent competitors from making, using and selling competing products. In addition, even where we have the right to control patent prosecution of patents and patent applications we have acquired or licensed from third parties, we may still be adversely affected or prejudiced by actions or inactions of our predecessors or licensors and their counsel that took place prior to our assuming control over patent prosecution. Our technology acquired or licensed from various third parties may be subject to retained rights. Our predecessors or licensors often retain certain rights under their agreements with us, including the right to use the underlying technology for noncommercial academic and research use, to publish general scientific findings from research related to the technology, and to make customary scientific and scholarly disclosures of information relating to the technology. It is difficult to monitor whether our predecessors or licensors limit their use of the technology to these uses, and we could incur substantial expenses to enforce our rights to our licensed technology in the event of misuse. 92 If we are limited in our ability to utilize acquired or licensed technologies, or if we lose our rights to critical in-licensed technology, we may be unable to successfully develop, out-license, market and sell our products, which could prevent or delay new product introductions. Our business strategy depends on the successful development of licensed and acquired technologies into commercial products. Therefore, any limitations on our ability to utilize these technologies may impair our ability to develop, out-license or market and sell our product candidates. Some of our intellectual property has been discovered through government funded programs and thus may be subject to federal regulations such as “march-in” rights, certain reporting requirements and a preference for U.S.-based companies. Compliance with such regulations may limit our exclusive rights, and limit our ability to contract with non-U.S. manufacturers. Some of the intellectual property rights we have acquired or licensed or may acquire or license in the future may have been generated through the use of U.S. government funding and may therefore be subject to certain federal regulations. For example, some of the research and development work on zilovertamab and ONCT-216 was funded by government research grants. As a result, the U.S. government may have certain rights to intellectual property embodied in our product candidates pursuant to the Bayh-Dole Act of 1980, or Bayh-Dole Act. These U.S. government rights include a non-exclusive, non- transferable, irrevocable worldwide license to use inventions for any governmental purpose. In addition, the U.S. government has the right, under certain limited circumstances, to require us to grant exclusive, partially exclusive, or non-exclusive licenses to any of these inventions to a third-party if it determines that: (i) adequate steps have not been taken to commercialize the invention; (ii) government action is necessary to meet public health or safety needs; or (iii) government action is necessary to meet requirements for public use under federal regulations (also referred to as “march-in rights”). The U.S. government also has the right to take title to these inventions if the grant recipient fails to disclose the invention to the government or fails to file an application to register the intellectual property within specified time limits. Intellectual property generated under a government funded program is also subject to certain reporting requirements, compliance with which may require us to expend substantial resources. In addition, the U.S. government requires that any products embodying any of these inventions or produced through the use of any of these inventions be manufactured substantially in the U.S. This preference for U.S. industry may be waived by the federal agency that provided the funding if the owner or assignee of the intellectual property can show that reasonable but unsuccessful efforts have been made to grant licenses on similar terms to potential licensees that would be likely to manufacture substantially in the U.S. or that under the circumstances domestic manufacture is not commercially feasible. This preference for U.S. industry may limit our ability to contract with non-U.S. product manufacturers for products covered by such intellectual property. To the extent any of our future intellectual property is also generated through the use of U.S. government funding, the provisions of the Bayh-Dole Act may similarly apply. With respect to state funding, specifically funding via the California Institute of Regenerative Medicine, or CIRM which has granted funds for the study of zilovertamab in combination with ibrutinib and a novel anti-cancer stem cell targeted therapy, the grantee has certain obligations and the state or CIRM has certain rights. For example, the grantee has an obligation to share intellectual property, including research results, generated by CIRM-funded research, for research use in California. In addition, the California government can exercise march-in rights if it determines that action is necessary because we or the grantee failed to achieve practical application of the CIRM-funded technology, because we failed to comply with agreed to access and pricing requirements, or because action is necessary to address a public health emergency declared by the governor of California. Intellectual property rights do not necessarily address all potential threats to our competitive advantage. 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. For example: • • • others may be able to develop products that are similar to our product candidates but that are not covered by the claims of the patents that we own or license; we or our licensors or predecessors might not have been the first to make the inventions covered by the issued patents or patent applications that we own or license; we or our licensors or predecessors might not have been the first to file patent applications covering certain of our inventions; 93 • • • • • • others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our intellectual property rights; it is possible that our or our licensor’s pending patent applications will not lead to issued patents; issued patents that we own or license may be held invalid or unenforceable, as a result of legal challenges by our competitors; 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 not develop additional proprietary technologies that are patentable; and the patents of others may have an adverse effect on our business. Should any of these events occur, it could significantly harm our business, results of operations and prospects. We rely on licensee relationships, and any disputes or litigation with our partners or termination or breach of any of the related agreements could reduce the financial resources available to us, including milestone payments and future royalty revenues. Our existing collaborations may not continue or be successful, and we may be unable to enter into future collaborative arrangements to develop and commercialize our unpartnered assets. If any of our collaborative partners breach or terminate their agreements with us or otherwise fail to conduct their collaborative activities successfully, our product development under these agreements will be delayed or terminated. Disputes or litigation may also arise with our collaborators (with us and/or with one or more third parties), including those over ownership rights to intellectual property, know-how or technologies developed with our collaborators. Such disputes or litigation could adversely affect our rights to one or more of our product candidates and could delay, interrupt or terminate the collaborative research, development and commercialization of certain potential products, create uncertainty as to ownership rights of intellectual property, or could result in litigation or arbitration. In addition, a significant downturn or deterioration in the business or financial condition of our collaborators or partners could result in a loss of expected revenue and our expected returns on investment. The occurrence of any of these problems could be time-consuming and expensive and could adversely affect our business. Our commercial success depends significantly on our ability to operate without infringing the patents and other proprietary rights of third parties. Claims by third parties that we infringe their proprietary rights may result in liability for damages or prevent or delay our developmental and commercialization efforts. Our commercial success depends in part on avoiding infringement of the patents and proprietary rights of third parties. However, our or our licensee’s research, development and commercialization activities may be subject to claims that we or our licensee infringes or otherwise violates patents or other intellectual property rights owned or controlled by third parties. Other entities may have or obtain patents or proprietary rights that could limit our or our licensee’s ability to make, use, sell, offer for sale or import our product candidates and products that may be approved in the future, or impair our competitive position. There is a substantial amount of litigation, both within and outside the U.S., involving patent and other intellectual property rights in the biopharmaceutical industry, including patent infringement lawsuits, oppositions, reexaminations, IPR proceedings and PGR proceedings before the USPTO and/or foreign patent offices. Numerous third-party U.S. and foreign issued patents and pending patent applications exist in the fields in which we are developing product candidates. There may be third-party patents or patent applications with claims to materials, formulations, methods of manufacture or methods for treatment related to the use or manufacture of our product candidates. As the biopharmaceutical industry expands and more patents are issued, the risk increases that our product candidates may be subject to claims of infringement of the patent rights of third parties. Because patent applications are maintained as confidential for a certain period of time, until the relevant application is published we may be unaware of third-party patents that may be infringed by commercialization of any of our product candidates, and we cannot be certain that we were the first to file a patent application related to a product candidate or technology. Moreover, because patent applications can take many years to issue, there may be currently-pending patent applications that may later result in issued patents that our product candidates may infringe. In addition, identification of third-party patent rights that may be relevant to our technology is difficult because patent searching is imperfect due to differences in terminology among patents, incomplete databases and the difficulty in assessing the meaning of patent claims. In addition, third parties may obtain patents in the future and claim that use of our 94 technologies infringes upon these patents. Any claims of patent infringement asserted by third parties would be time consuming and could: • • • • • • • • result in costly litigation that may cause negative publicity; divert the time and attention of our technical personnel and management; cause development delays; subject us to an injunction preventing us from making, using, selling, offering for sale, or importing our products; prevent us from commercializing any of our product candidates until the asserted patent expires or is held finally invalid or not infringed in a court of law; require us to develop non-infringing technology, which may not be possible on a cost-effective basis; subject us to significant liability to third parties; or require us to enter into royalty or licensing agreements, which may not be available on commercially reasonable terms, or at all, or which might be non-exclusive, which could result in our competitors gaining access to the same technology. Although no third-party has asserted a claim of patent infringement against us as of December 31, 2021, others may hold proprietary rights that could prevent our product candidates from being marketed. Any patent-related legal action against us claiming damages and seeking to enjoin activities relating to our product candidates or processes could subject us to potential liability for damages, including treble damages if we were determined to willfully infringe, and require us to obtain a license to manufacture or develop our product candidates. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from our business. We cannot predict whether we would prevail in any such actions or that any license required under any of these patents would be made available on commercially reasonable terms, if at all. Moreover, even if we or our future strategic partners were able to obtain a license, the rights may be nonexclusive, which could result in our competitors gaining access to the same intellectual property. In addition, we cannot be certain that we could redesign our product candidates or processes to avoid infringement, if necessary. Accordingly, an adverse determination in a judicial or administrative proceeding, or the failure to obtain necessary licenses, could prevent us from developing and commercializing our product candidates, which could harm our business, financial condition and operating results. Parties making claims against us may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation or administrative proceedings, there is a risk that some of our confidential information could be compromised by disclosure. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise additional funds or otherwise have a material adverse effect on our business, results of operations, financial condition and prospects. We may be involved in lawsuits to protect or enforce our patents or the patents of our licensors, which could be expensive, time-consuming and unsuccessful. Further, our issued patents could be found invalid or unenforceable if challenged in court. Competitors may infringe our intellectual property rights or those of our licensors. To prevent infringement or unauthorized use, we and/or our licensors may be required to file infringement claims, which can be expensive and time consuming. In addition, in a patent infringement proceeding, a court may decide that a patent we own or license is not valid, is unenforceable and/or is not infringed. If we or any of our licensors or potential future collaborators were to initiate legal proceedings against a third-party to enforce a patent directed at one of our product candidates, the defendant could counterclaim that our or our licensor’s patent is invalid and/or unenforceable in whole or in part. In patent litigation, defendant counterclaims alleging invalidity and/or unenforceability are commonplace. Grounds for a validity challenge include an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness, lack of written description or non-enablement. Grounds for an unenforceability assertion could include an allegation that someone connected with prosecution of the patent withheld relevant information from the USPTO or made a misleading statement during prosecution. 95 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 such product candidate. In addition, if the breadth or strength of protection provided by our patents and patent applications or those of our licensors is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates. Such a loss of patent protection would have a material adverse impact on our business. Even if resolved in our favor, litigation or other legal proceedings relating to our or our licensor’s intellectual property rights may cause us to incur significant expenses and could distract our technical and management personnel from their normal responsibilities. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available for development activities or any future sales, marketing or distribution activities. We or our licensor may not have sufficient financial or other resources to conduct or participate in such litigation or proceedings adequately. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we or our licensor can because of their greater financial resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could compromise our ability to compete in the marketplace. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation or other legal proceedings relating to our intellectual property rights, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation or other proceedings. Intellectual property litigation may lead to unfavorable publicity that harms our reputation and causes the market price of our common shares to decline. During the course of any intellectual property litigation, there could be public announcements of the initiation of the litigation as well as results of hearings, rulings on motions, and other interim proceedings in the litigation. If securities analysts or investors regard these announcements as negative, the perceived value of our existing products, programs or intellectual property could be diminished. Accordingly, the market price of shares of our common stock may decline. Such announcements could also harm our reputation or the market for our future products, which could have a material adverse effect on our business. Derivation or interference proceedings may be necessary to determine priority of inventions, and an unfavorable outcome may require us to cease using the related technology or to attempt to license rights from the prevailing party. Derivation or interference proceedings provoked by third parties or brought by us or our licensors or declared by the USPTO or similar proceedings in foreign patent offices may be necessary to determine the priority of inventions with respect to our or our licensor’s patents or patent applications. An unfavorable outcome could require us to cease using the related technology or to attempt to license rights to it from the prevailing party. Our business could be harmed if the prevailing party does not offer us a license on commercially reasonable terms. Our or our licensor’s defense of such proceedings may fail and, even if successful, may result in substantial costs and distract our management and other employees. In addition, the uncertainties associated with such proceedings could have a material adverse effect on our ability to raise the funds necessary to continue our clinical trials, continue our research programs, license necessary technology from third parties or enter into development or manufacturing partnerships that would help us bring our product candidates to market. Recent patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents. On September 16, 2011, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, was signed into law. The Leahy-Smith Act includes a number of significant changes to U.S. patent law. These include provisions that affect the way patent applications will be prosecuted and may also affect patent litigation. In particular, under the Leahy-Smith Act, the U.S. transitioned in March 2013 to a “first inventor to file” system in which, assuming that other requirements of patentability are met, the first inventor to file a patent application will be entitled to the patent regardless of whether a third-party was first to invent the claimed invention. A third-party that files a patent application in the USPTO after March 2013 but before we could therefore be awarded a patent covering an invention of our even if we had made the invention before it was made by such third-party. This will require us to be cognizant going forward of the time from invention to filing of a patent application. Furthermore, our ability to obtain and maintain valid and enforceable patents depends on whether the differences between our technology and the prior art allow our technology to be patentable over the prior art. Since patent applications in the U.S. and most 96 other countries are confidential for a period of time after filing or until issuance, we cannot be certain that we or our licensor was the first to either (1) file any patent application related to our product candidates or (2) invent any of the inventions claimed in our or our licensor’s patents or patent applications. The Leahy-Smith Act also includes a number of significant changes that affect the way patent applications will be prosecuted and also may affect patent litigation. These include allowing third-party submission of prior art to the USPTO during patent prosecution and additional procedures to attack the validity of a patent by USPTO administered post-grant proceedings, including PGR, IPR, and derivation proceedings. An adverse determination in any such submission or proceeding could reduce the scope or enforceability of, or invalidate, our patent rights, which could adversely affect our competitive position. Because of a lower evidentiary standard in USPTO proceedings compared to the evidentiary standard in U.S. federal courts necessary to invalidate a patent claim, a third-party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a claim invalid even though the same evidence would be insufficient to invalidate the claim if first presented in a district court action. Accordingly, a third-party may attempt to use the USPTO procedures to invalidate our or our licensor’s patent claims that would not have been invalidated if first challenged by the third-party as a defendant in a district court action. Thus, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our or our licensor’s patent applications and the enforcement or defense of our or our licensor’s issued patents, all of which could have a material adverse effect on our business, financial condition, results of operations and prospects. Changes in U.S. patent law, or laws in other countries, could diminish the value of patents in general, thereby impairing our ability to protect our product candidates. As is the case with other biopharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and enforcing patents in the biopharmaceutical industry involves a high degree of technological and legal complexity. Therefore, obtaining and enforcing biopharmaceutical patents is costly, time consuming and inherently uncertain. Changes in either the patent laws or in the interpretations of patent laws in the U.S. and other countries may diminish the value of our intellectual property rights and may increase the uncertainties and costs surrounding the prosecution of patent applications and the enforcement or defense of issued patents. We cannot predict the breadth of claims that may be allowed or enforced in our or our licensor’s patents or in third-party patents. In addition, Congress or other foreign legislative bodies may pass patent reform legislation that is unfavorable to us. For example, the U.S. Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our and our licensor’s ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. 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 would weaken our or our licensor’s ability to obtain new patents or to enforce our existing patents and patents we might obtain in the future. We may be subject to claims challenging the inventorship or ownership of our patents and other intellectual property. We may also be subject to claims that former employees or other third parties have an ownership interest in our patents or other intellectual property. Litigation may be necessary to defend against these and other claims challenging inventorship or ownership. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights. Such an outcome could have a material adverse effect on our business. Even if we are successful in defending against such claims, litigation could result in substantial costs and distraction to management and other employees. 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 U.S., if all maintenance fees are timely paid, the natural expiration of a patent is generally 20 years from its earliest U.S. non-provisional filing date. Various extensions may be available, but the life of a patent, and the protection it affords, is limited. Even if patents covering our product candidates are obtained, once the patent life has expired, we may be open to competition from competitive products. Given the 97 amount of time required for the development, testing and regulatory review of product candidates, patents protecting our product candidates might expire before or shortly after such candidates are commercialized. As a result, our patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to our product candidates. If we do not obtain patent term extension for our product candidates, our business may be harmed. Depending upon the timing, duration and specifics of FDA marketing approval of our product candidates, one or more of our or our licensor’s U.S. patents may be eligible for limited patent term restoration under the Drug Price Competition and Patent Term Restoration Act of 1984, or the Hatch- Waxman Amendments. The Hatch-Waxman Amendments permit a patent restoration term of up to five years as compensation for patent term lost during product development and the FDA regulatory review process. A maximum of one patent may be extended per FDA approved product as compensation for the patent term lost during the FDA regulatory review process. A patent term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval and only those claims covering such approved drug product, a method for using it or a method for manufacturing it may be extended. Patent term extension may also be available in certain foreign countries upon regulatory approval of our product candidates. However, we may not be granted an extension because of, for example, failing to apply within applicable deadlines, failing to apply prior to expiration of relevant patents or otherwise failing to satisfy applicable requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less than we request. If we are unable to obtain patent term extension or restoration or the term of any such extension is less than we request, our competitors may obtain approval of competing products following our or our licensor’s patent expiration, and our revenue 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. We may not be able to protect our intellectual property rights throughout the world. Although we and our licensors have issued patents and pending patent applications in the U.S. and certain other countries, filing, prosecuting and defending patents in all countries throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the U.S. can be less extensive than those in the U.S. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the U.S. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the U.S. or from selling or importing products made using our inventions in and into the U.S. or other jurisdictions. Competitors may use our technologies in jurisdictions where we or our licensor has 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 U.S. These products may compete with our product candidates, and our and our licensor’s patents or other intellectual property rights may not be effective or sufficient to prevent them from competing. Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of many foreign countries do not favor the enforcement of patents and other intellectual property protection, 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. 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 or our licensor 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 or our licensor’s 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. Many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of such patent. If we or our licensor is forced to grant a license to third parties with respect to any patents relevant to our business, our competitive position may be impaired, and our business, financial condition, results of operations and prospects may be adversely affected. 98 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 non-compliance with these requirements. Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and/or applications will be due to the USPTO and various foreign patent offices at various points over the lifetime of our and our licensors’ patents and/or applications. We have systems in place to remind us to pay these fees, and we rely on third parties to pay these fees when due. Additionally, the USPTO and various foreign patent office’s 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. If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed. In addition, we rely on the protection of our trade secrets, including unpatented know-how, technology and other proprietary information to maintain our competitive position. Although we have taken steps to protect our trade secrets and unpatented know-how, including entering into confidentiality agreements with third parties, and confidential information and inventions agreements with employees, consultants and advisors, we cannot provide any assurances that all such agreements have been duly executed, and any of these parties may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time consuming, and the outcome is unpredictable. In addition, some courts inside and outside the U.S. are less willing or unwilling to protect trade secrets. Moreover, third parties may still obtain this information or may come upon this or similar information independently, and we would have no right to prevent them from using that technology or information to compete with us. If any of these events occurs or if we otherwise lose protection for our trade secrets, the value of this information may be greatly reduced and our competitive position would be harmed. If we do not apply for patent protection prior to such publication or if we cannot otherwise maintain the confidentiality of our proprietary technology and other confidential information, then our ability to obtain patent protection or to protect our trade secret information may be jeopardized. We may be subject to claims that we have wrongfully hired an employee from a competitor or that we or our employees have wrongfully used or disclosed alleged confidential information or trade secrets of their former employers. As is common in the biopharmaceutical industry, in addition to our employees, we engage the services of consultants to assist us in the development of our product candidates. Many of these consultants, and many of our employees, were previously employed at, or may have previously provided or may be currently providing consulting services to, other biopharmaceutical companies including our competitors or potential competitors. We may become subject to claims that we, our employees or a consultant inadvertently or otherwise used or disclosed trade secrets or other information proprietary to their former employers or their former or current clients. Litigation may be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel, which could adversely affect our business. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to our management team and other employees. 99 Risks Related to Our Common Stock The trading price of the shares of our common stock may be highly volatile, and purchasers of our common stock may incur substantial losses. Our stock price is likely to be volatile. The stock market in general and the market for stock of biopharmaceutical companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. As a result of this volatility, investors may not be able to sell their common stock at or above their purchase price. The market price for our common stock may be influenced by those factors discussed in this “Risk Factors” section and many others, including: • • • • • • • • • • • • • • • • • • • • • our or our collaborators ability to enroll patients in our ongoing and planned clinical trials; results of our clinical trials and preclinical studies, and the results of the trials of our competitors or those of other companies in our market sector; regulatory approval of our product candidates, or limitations to specific label indications or patient populations for its use, or changes or delays in the regulatory review process; regulatory developments in the U.S. and foreign countries; changes in the structure of healthcare payment systems, especially in light of current reforms to the U.S. healthcare system; the success or failure of our efforts to acquire, license or develop additional product candidates; innovations or new products developed by us or our competitors; announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures or capital commitments; announcements regarding the results of discovery efforts and preclinical, clinical and commercial activities by us, or those of our competitors; manufacturing, supply or distribution delays or shortages; any changes to our relationship with any manufacturers, suppliers, licensors, future collaborators or other strategic partners; achievement of expected product sales and profitability; variations in our financial results or those of companies that are perceived to be similar to us; market conditions in the biopharmaceutical sector and issuance of securities analysts’ reports or recommendations; trading volume of our common stock; establishment of short positions by holders or non-holders of our common stock; an inability to obtain additional funding; sales of our stock by insiders and stockholders; general economic, industry and market conditions or other events or factors, many of which are beyond our control; additions or departures of key personnel; and intellectual property, product liability or other litigation against us. In addition, in the past, stockholders have initiated class action lawsuits against biopharmaceutical companies following periods of volatility in the market prices of these companies’ stock. Such litigation, if instituted against us, could cause us to incur substantial costs and divert management’s attention and resources, which could have a material adverse effect on our business, financial condition and results of operations. Our executive officers, directors and principal stockholders, if they choose to act together, will continue to control or significantly influence all matters submitted to stockholders for approval. Furthermore, two of our directors have been appointed by one of our principal stockholders. As of December 31, 2021, our executive officers, directors and greater than 5% stockholders, in the aggregate, owned approximately 9.30% of our outstanding common stock. Furthermore, two of our directors are affiliated with our largest stockholder, SPH USA. As a result, such persons or their appointees to our board of directors, acting together, will have the ability to control or significantly influence all matters submitted to our board of directors or stockholders for approval, including the appointment of our management, the election and removal of directors and approval of any significant transaction, as well as our management and business affairs. This concentration of ownership may have the effect of delaying, deferring or preventing a change in control, impeding a merger, consolidation, takeover or other business combination involving us, or discouraging a potential acquiror from making a tender offer or otherwise attempting to obtain control of our business, even if such a transaction would benefit other stockholders. 100 We do not currently intend to pay dividends on our common stock, and, consequently, your ability to achieve a return on your investment will depend on appreciation, if any, in the price of our common stock. We have never declared or paid any cash dividend on our common stock. We currently anticipate that we will retain future earnings for the development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. In addition, the terms of any future debt agreements may preclude us from paying dividends. Any return to stockholders will therefore be limited to the appreciation of their stock. There is no guarantee that shares of our common stock will appreciate in value or even maintain the price at which stockholders have purchased their shares. Sales of a substantial number of shares of our common stock by our stockholders in the public market could cause our stock price to fall. Sales of a substantial number of shares of our common stock in the public market or the perception that these sales might occur could significantly reduce the market price of our common stock and impair our ability to raise adequate capital through the sale of additional equity securities. As of December 31, 2021, 44,830,509 shares of our outstanding common stock are freely tradable, without restriction, in the public market, unless they are purchased by one of our affiliates. As of December 31, 2021, up to 12,522,086 shares of common stock that are either subject to outstanding warrants, options or reserved for future issuance under our equity incentive plans will become eligible for sale in the public market to the extent permitted by the provisions of various vesting schedules and Rule 144 and Rule 701 under the Securities Act of 1933, as amended, or the Securities Act. If these additional shares of common stock are sold, or if it is perceived that they will be sold, in the public market, the trading price of our common stock could decline. Provisions in our charter documents and under Delaware law could discourage a takeover that stockholders may consider favorable and may lead to entrenchment of management. Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that could significantly reduce the value of our shares to a potential acquiror or delay or prevent changes in control or changes in our management without the consent of our board of directors. The provisions in our charter documents include the following: • • • • • • • • • a classified board of directors with three-year staggered terms, which may delay the ability of stockholders to change the membership of a majority of our board of directors; no cumulative voting in the election of directors, which limits the ability of minority stockholders to elect director candidates; the exclusive right of our board of directors, unless the board of directors’ grants such right to the stockholders, to elect a director to fill a vacancy created by the expansion of the board of directors or the resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on our board of directors; the prohibition on removal of directors without cause due to the classified board of directors; the ability of our board of directors to authorize the issuance of shares of preferred stock and to determine the price and other terms of those shares, including preferences and voting rights, without stockholder approval, which could be used to significantly dilute the ownership of a hostile acquiror; the ability of our board of directors to alter our amended and restated bylaws without obtaining stockholder approval; the required approval of at least 66-2/3% of the shares entitled to vote to adopt, amend or repeal our amended and restated bylaws or repeal certain provisions of our amended and restated certificate of incorporation; a prohibition on stockholder action by written consent, which forces stockholder action to be taken at an annual or special meeting of our stockholders; an exclusive forum provision providing that the Court of Chancery of the State of Delaware will be the exclusive forum for certain actions and proceedings; 101 • • the requirement that a special meeting of stockholders may be called only by the chairman of the board of directors, the chief executive officer or the board of directors, which may delay the ability of our stockholders to force consideration of a proposal or to take action, including the removal of directors; and advance notice procedures that stockholders must comply with in order to nominate candidates to our board of directors or to propose matters to be acted upon at a stockholders’ meeting, which may discourage or deter a potential acquiror from conducting a solicitation of proxies to elect the acquiror’s own slate of directors or otherwise attempting to obtain control of us. We are also subject to the anti-takeover provisions contained in Section 203 of the Delaware General Corporation Law. Under Section 203, a corporation may not, in general, engage in a business combination with any holder of 15% or more of its capital stock unless the holder has held the stock for three years or, among other exceptions, the board of directors has approved the transaction. Our amended and restated bylaws provide that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees. Our amended and restated bylaws provide that the Court of Chancery of the State of Delaware is the exclusive forum for any derivative action or proceeding brought on our behalf, any action asserting a breach of fiduciary duty, any action asserting a claim against us arising pursuant to the Delaware General Corporation Law, our amended and restated certificate of incorporation or our amended and restated bylaws, or any action asserting a claim against us that is governed by the internal affairs doctrine. These choice of forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers and other employees. By agreeing to this provision, however, stockholders will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations thereunder. Furthermore, the enforceability of similar choice of forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that a court could find these types of provisions to be inapplicable or unenforceable. If a court were to find the choice of forum provisions in our amended and restated bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could adversely affect our business and financial condition. Our ability to use net operating loss (“NOL”) carryforwards and other tax attributes may be limited. We have incurred substantial losses during our history and do not expect to become profitable in the near future, and we may never achieve profitability. To the extent that we continue to generate taxable losses, unused losses will carry forward to offset future taxable income, if any, until such unused losses expire (if at all). As of December 31, 2021, we had federal and state NOL carryforwards of approximately $81.5 million and $59.4 million, respectively. Approximately $55.2 million of NOLs do not expire and the remaining federal and state NOL carryforward will begin to expire in 2033 and 2029, respectively, unless previously utilized. As of December 31, 2021, we had federal and state research and development credit carryforwards of approximately $2.1 million and $1.3 million, respectively. The federal research and development credit carryforwards will begin expiring in 2034, unless previously utilized. The state research and development credits do not expire. Under the Tax Act, federal NOLs generated in taxable years ending after December 31, 2017, may be carried forward indefinitely but federal NOLs generated in taxable years beginning after December 31, 2017 may only be used to offset 80% of our taxable income annually. Under Sections 382 and 383 of the Code, our NOL and research and development tax credit carryforwards may become subject to an annual limitation in the event of certain cumulative changes in the ownership interest of significant stockholders over a three-year period in excess of 50 percentage points. Our ability to utilize our NOL carryforwards and other tax attributes to offset future taxable income or tax liabilities may be limited as a result of ownership changes, including changes resulting from our Merger, as described elsewhere. We have not yet determined the amount of the cumulative change in our ownership resulting from the Merger or other transactions, or any resulting limitations on our ability to utilize our NOL carryforwards and other tax attributes. If we earn taxable income, such limitations could result in increased future tax liability to us and our future cash flows could be adversely affected. We have recorded a full valuation allowance related to our NOLs and other deferred tax assets due to the uncertainty of the ultimate realization of the future benefits of those assets. 102 Our stockholders prior to the Merger who hold CVRs may not receive any payment on the CVRs and the CVRs may otherwise expire valueless. We are party to a CVR Agreement, dated as of June 7, 2019 and as amended on November 1, 2021, or the CVR Agreement, pursuant to which, for each share of GTx common stock held, stockholders of record as of immediately prior to the Merger received one contingent value right, or CVR, entitling such holders to receive in the aggregate 50% of any net proceeds received during the 15-year period after the closing of the Merger from the grant, sale or transfer of rights to our DAARI program that occurs during the 10-year period after the closing of the Merger (or in the 11th year if based on a term sheet approved during the initial 10-year period) and, if applicable, to receive royalties on the sale of any DAARI products or SARM products by us during the 15-year period after the closing of the Merger. As of December 31, 2021, no transactions or net sales relating to the DAARI technology had occurred. The CVRs are not transferable, will not have any voting or dividend rights, and interest will not accrue on any amounts potentially payable on the CVRs. Accordingly, the right of any stockholder of record as of immediately prior to the Merger to receive any future payment on or derive any value from the CVRs will be contingent solely upon the achievement of the foregoing events within the time periods specified in the CVR Agreement and if these events are not achieved for any reason within the time periods specified in the CVR Agreement, no payments will be made under the CVRs, and the CVRs will expire valueless. In addition, we (as successor in interest to GTx) have agreed only to use commercially reasonable efforts to develop DAARI products, subject to certain limitations, which allows for the consideration of a variety of factors in determining the efforts that we are required to use to develop DAARI products, and we are not required to take all possible actions to continue efforts to develop DAARI products. Accordingly, under certain circumstances we may not be required to continue efforts to develop DAARI products, or may allocate resources to other projects, which would have an adverse effect on the value, if any, of the CVRs. Furthermore, the CVRs will be unsecured obligations of our company and all payments under the CVRs, all other obligations under the CVR Agreement and the CVRs and any rights or claims relating thereto will be subordinated in right of payment to the prior payment in full of all of our current or future senior obligations. Finally, the U.S. federal income tax treatment of the CVRs is unclear. There is no legal authority directly addressing the U.S. federal income tax treatment of the receipt of, and payments on, the CVRs, and there can be no assurance that the IRS, would not assert, or that a court would not sustain, a position that could result in adverse U.S. federal income tax consequences to holders of the CVRs. General Risk Factors Our failure to meet the continued listing requirements of the Nasdaq Capital Market could result in a delisting of our common stock. If we fail to satisfy the continued listing requirements of the Nasdaq Capital Market, or Nasdaq, such as the corporate governance requirements or the minimum closing bid price requirement, Nasdaq may take steps to delist our common stock. Such a delisting would likely have a negative effect on the price of our common stock and would impair your ability to sell or purchase our common stock when you wish to do so. In the event of a delisting, we can provide no assurance that any action we take to restore compliance with listing requirements would allow our common stock to become listed again, stabilize the market price or improve the liquidity of our common stock, prevent our common stock from dropping below the Nasdaq minimum bid price requirement or prevent future non-compliance with Nasdaq’s listing requirements. We incur significant costs as a result of operating as a public company, and our management is required to devote substantial time to compliance initiatives. As a public company, we incur significant legal, accounting and other expenses that we did not incur as a private company. We are subject to the reporting requirements of the Exchange Act, which will require, among other things, that we file with the Securities and Exchange Commission, or the SEC, annual, quarterly and current reports with respect to our business and financial condition. In addition, Sarbanes-Oxley, as well as rules subsequently adopted by the SEC and Nasdaq to implement provisions of Sarbanes-Oxley, impose significant requirements on public companies, including requiring establishment and maintenance of effective disclosure and 103 financial controls and changes in corporate governance practices. Further, pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the SEC has adopted additional rules and regulations in these areas, such as mandatory “say on pay” voting requirements that apply to us. Stockholder activism, the current political environment and the current high level of government intervention and regulatory reform may lead to substantial new regulations and disclosure obligations, which may lead to additional compliance costs and impact the manner in which we operate our business in ways we cannot currently anticipate. We expect the rules and regulations applicable to public companies to substantially increase our legal and financial compliance costs and to make some activities more time-consuming and costly. If these requirements divert the attention of our management and personnel from other business concerns, they could have a material adverse effect on our business, financial condition and results of operations. The increased costs will increase our net loss and may require us to reduce costs in other areas of our business or increase the prices of our products or services. For example, we expect these rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to incur substantial costs to maintain the same or similar coverage. We cannot predict or estimate the amount or timing of additional costs we may incur to respond to these requirements. The impact of these requirements could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees or as executive officers. If securities or industry analysts do not publish research or reports or publish unfavorable research or reports about our business, our stock price and trading volume could decline. The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us, our business, our market or our competitors. We do not currently have and may never obtain research coverage by securities and industry analysts. If no securities or industry analysts commence coverage of our company, the trading price for our common stock would be negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who covers us downgrades our stock, our stock price would likely decline. If one or more of these analysts ceases to cover us or fails to regularly publish reports on us, interest in our stock could decrease, which could cause our stock price or trading volume to decline. If we fail to maintain proper and effective internal control over financial reporting, our ability to produce accurate and timely financial statements could be impaired, investors may lose confidence in our financial reporting and the trading price of our common stock may decline. Pursuant to Section 404 of Sarbanes-Oxley, we are required to report upon the effectiveness of our internal control over financial reporting. Additionally, our independent registered public accounting firm is required to attest to the effectiveness of our internal control over financial reporting. The rules governing the standards that must be met for management to assess our internal control over financial reporting are complex and require significant documentation, testing and possible remediation. To comply with the requirements of being a reporting company under the Exchange Act, we have been required to upgrade our information technology systems; implement additional financial and management controls, reporting systems and procedures; and hire additional accounting and finance staff. If we or, if required, our auditors are unable to conclude that our internal control over financial reporting is effective, investors may lose confidence in our financial reporting and the trading price of our common stock may decline. We cannot assure you that there will not be material weaknesses or significant deficiencies in our internal control over financial reporting in the future. Any failure to maintain internal control over financial reporting could severely inhibit our ability to accurately report our financial condition, results of operations or cash flows. 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 or significant deficiency in our internal control over financial reporting, investors may lose 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 Nasdaq, 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. 104 We may become involved in the future, in securities class action litigation that could divert management’s attention, adversely affect our business and subject us to significant liabilities. In the past, securities class action litigation has often been brought against a company following volatility in the market price of its securities. This risk is especially relevant for us, because biotechnology and pharmaceutical companies have experienced significant stock price volatility in recent years. Any future lawsuits to which we may become a party are subject to inherent uncertainties and will likely be expensive and time-consuming to investigate, defend and resolve, and will divert our management’s attention and financial and other resources. The outcome of litigation is necessarily uncertain, and we could be forced to expend significant resources in the defense of future lawsuits, and we may not prevail. Any litigation to which we may become a party may result in an onerous or unfavorable judgment that may not be reversed upon appeal or in payments of substantial monetary damages or fines, or we may decide to lawsuits on similarly unfavorable terms, which could adversely affect our business, financial condition, results of operations or stock price. Unstable market and economic conditions may have serious adverse consequences on our business, financial condition and stock price. The global credit and financial markets have recently experienced extreme volatility and disruptions, including severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates and uncertainty about economic stability. The financial markets and the global economy may also be adversely affected by the current or anticipated impact of military conflict, including the conflict between Russia and Ukraine, terrorism or other geopolitical events. Sanctions imposed by the U.S. and other countries in response to such conflicts, including the one in Ukraine, may also adversely impact the financial markets and the global economy, and any economic countermeasures by affected countries and others could exacerbate market and economic instability. There can be no assurance that further deterioration in credit and financial markets and confidence in economic conditions will not occur. Our general business strategy may be adversely affected by any such economic downturn, volatile business environment or continued unpredictable and unstable market conditions. 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 clinical development plans. In addition, there is a risk that one or more of our current service providers, manufacturers and other partners may not survive an economic downturn, which could directly affect our ability to attain our operating goals on schedule and on budget. 105 Item 1B.

Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities. Market Information. Our common stock is listed on The Nasdaq Capital Market under the ticker symbol “ONCT”. As of March 3, 2022, there were approximately 117 holders of record of our common stock. This number was derived from our stockholder records and does not include beneficial owners of our common stock whose shares are held in the name of various dealers, clearing agencies, banks, brokers and other fiduciaries. Dividend Policy. We have never declared or paid any dividends on our common stock. We currently intend to retain all available funds and any future earnings, if any, to fund the development and expansion of our business and we do not anticipate paying any cash dividends in the foreseeable future. Recent Sales of Unregistered Securities. None. Item 6. [Reserved]. 107 Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. The following discussion should be read in conjunction with the consolidated financial statements and the related notes and other financial information included elsewhere in this Annual Report. Some of the information contained in this discussion and analysis or set forth elsewhere in this Annual Report, including information with respect to our plans and strategy for our business and future financial performance, includes forward-looking statements that are based upon current beliefs, plans and expectations and involve risks, uncertainties and assumptions. You should review the “Risk Factors” section of this Annual Report for a discussion of important factors that could cause our actual results and the timing of selected events to differ materially from those described in or implied by the forward-looking statements contained in the following discussion and analysis. Please also see the section within Part I of this Annual Report entitled “Cautionary Note Regarding Forward-Looking Statements.” Overview We are a clinical-stage biopharmaceutical company focused on the development of novel oncology therapies for cancers with critical unmet medical need. Our development efforts are focused on promising, yet untapped, biological pathways implicated in cancer generation or progression. Our pipeline includes: • Zilovertamab (formerly cirmtuzumab or UC-961) is an investigational, humanized, potentially first-in-class, monoclonal antibody designed to: (i) inhibit Receptor tyrosine kinase-like Orphan Receptor 1, or ROR1, a growth factor receptor that is widely expressed on many tumors and that activates pathways leading to increased tumor proliferation, invasiveness and drug resistance, and (ii) bind to a specific functionally important epitope of ROR1. After reaching an agreement regarding the study design and major details with the U.S. Food and Drug Administration (FDA), zilovertamab is planned to be evaluated in our potentially pivotal Phase 3 clinical trial of zilovertamab for the treatment of patients with relapsed or refractory MCL, which is expected to be initiated in the second quarter of 2022. The Phase 3 clinical trial ZILO-301 is entitled, “Randomized, Double-blind, Placebo-controlled, Multi-center Phase 3 Study of Zilovertamab (A ROR1 Antibody) Plus Ibrutinib Versus Ibrutinib Plus Placebo in Patients with Relapsed or Refractory Mantle Cell Lymphoma.” Zilovertamab is currently being evaluated in the Cirmtuzumab and Ibrutinib for Relapsed Lymphoma or Leukemia, or CIRLL, study, a Phase 1/2 clinical trial in combination with ibrutinib for the treatment of patients with B-cell lymphoid malignancies, including mantle cell lymphoma, or MCL, and chronic lymphocytic leukemia, or CLL. As of January 31, 2022, we have completed the enrollment of patients with MCL and CLL in the Phase 1/2 CIRLL study, and those patients are completing therapy or are in long-term follow-up. In addition, we are supporting two investigator-sponsored studies being conducted at the UC San Diego School of Medicine, or UC San Diego, a: (i) Phase 2 clinical trial for metastatic castration-resistant prostate cancer study, and (ii) Phase 2 clinical trial of zilovertamab in combination with venetoclax, a Bcl-2 inhibitor, in patients with relapsed/refractory CLL. • ONCT-808, our lead cell therapy product candidate, is: (i) an autologous chimeric antigen receptor T cell, or CAR-T, therapy that targets ROR1, (ii) in preclinical development as a potential treatment for hematologic malignancies and solid tumors, (iii) highly expressed by multiple solid tumors and hematological malignancies and confers both an aggressive phenotype and survival advantage to tumor cells, and (iv) being developed in collaboration with the Karolinska Institutet and under agreements with Lentigen Technology, Inc. (lentivirus manufacturing) and Miltenyi Biotec B.V. & Co. KG. (cell processing). We are performing preclinical activities to support the submission to the FDA of an Investigational New Drug Application, or IND, which we expect to submit in mid-2022. • ONCT-534 (formerly GTX-534), a dual action androgen receptor inhibitor, or DAARI, product candidate is in preclinical development as a potential treatment for advanced castration-resistant prostate and other androgen-receptor cancers. This program was acquired in the GTx Merger (described below) and was previously known as the selective androgen receptor degrader, or SARD, program. 108 • ONCT-216 (formerly TK216) is an investigational small molecule that is designed to inhibit the ETS, or E26 Transformation Specific, family of oncoproteins, has shown in preclinical studies to alter gene transcription and RNA processing and leads to increased cell proliferation and invasion. ONCT- 216 is being evaluated in a Phase 1/2 clinical trial as a single agent and in combination with vincristine in patients with relapsed or refractory Ewing sarcoma, a rare pediatric cancer. The active Phase 2 expansion cohort targeting up to 21 evaluable Ewing sarcoma patients is designed to evaluate clinical responses to single agent ONCT-216 using an optimized dosing regimen, treating patients for 28 days per cycle with the next cycle starting immediately after the prior one, to intensify the amount of ONCT-216 administered over time. Since the inception of privately-held Oncternal Therapeutics, Inc. in 2013, we have devoted most of our resources to organizing and staffing, business planning, raising capital, acquiring product candidates and securing related intellectual property rights and advancing our zilovertamab and ONCT-216 clinical development programs as well as our ONCT-808 and ONCT-534 preclinical programs. Under research subaward agreements between us and UC San Diego, we are eligible to receive approximately $14.4 million in development milestones during the award project period, estimated to be from October 1, 2017 to March 31, 2022. Through December 31, 2021, we have funded our operations primarily through: (i) gross proceeds of $125.0 million from the issuance of common stock, (ii) gross proceeds of $49.0 million from the issuance of convertible preferred stock, (iii) receipt of $13.9 million in subaward grant payments received from UC San Diego, and (iv) cash proceeds of $18.3 million received in connection with the closing of the merger with GTx, Inc. in June 2019, or the GTx Merger. As of December 31, 2021, we had cash and cash equivalents of $90.8 million and no debt. We have incurred net losses in each year since inception. Our ability to generate product revenue sufficient to achieve profitability will depend heavily on the successful development and eventual commercialization of one or more of our current or future product candidates. Our net loss was $31.3 million for the year ended December 31, 2021. As of December 31, 2021, we had an accumulated deficit of $114.1 million. Substantially all of our net losses have resulted from costs incurred in connection with: (i) advancing our research and development programs, (ii) general and administrative costs associated with our operations, including the costs associated with operating as a public company, and (iii) in-process research and development costs associated with the GTX Merger. We expect to continue to incur significant and increasing operating losses for at least the next several years. We expect that our expenses and capital funding requirements will increase substantially in connection with our ongoing activities, particularly if and as we: • • • • • • • • • • • • • • advance zilovertamab through clinical development in multiple indications, with a primary focus in MCL; advance our ROR-1 targeting cell therapy program, which includes ONCT-808 to clinical development, initially in hematological malignancies; generate clinical proof-of-concept data with ONCT-216 in Ewing sarcoma, an orphan pediatric cancer indication; advance ONCT-534 into clinical development, initially in castration resistant prostate cancer and then other AR-driven diseases; respond to the impacts of the COVID-19 pandemic, which has slowed enrollment into our clinical trials and impacted our supply chain activities; evaluate zilovertamab in additional ROR1-positive hematologic malignancies; evaluate ONCT-216 in additional malignancies with ETS fusion proteins or overexpression; continue to develop additional product candidates; acquire or in‑license other product candidates and technologies; maintain, expand and protect our intellectual property portfolio; establish a commercial manufacturing source and secure supply chain capacity sufficient to provide commercial quantities of any product candidates for which we may obtain regulatory approval; seek regulatory approvals for any product candidates that successfully complete clinical trials; establish a sales, marketing and distribution infrastructure to commercialize any products for which we may obtain regulatory approval; and add operational, financial and management information systems and personnel, including personnel to support our planned product development and future commercialization efforts. We will not generate product sales revenue unless and until we successfully complete clinical development and obtain regulatory approval for our product candidates. If we obtain regulatory approval for any of our product 109 candidates and do not enter into a commercialization partnership, we expect to incur significant expenses related to developing our internal commercialization capability to support product sales, marketing and distribution. In addition, we expect to incur additional costs associated with operating as a public company. As a result, we believe we will need substantial additional funding to support our continuing operations and pursue our business strategy. Until such time as we can generate significant product sales revenue, if ever, we expect to finance our operations through a combination of equity offerings, debt financings, government funding, or other sources, including potentially collaborations, licenses and other similar arrangements. We may not be able to raise additional funds or enter into such other agreements or arrangements when needed on favorable terms, or at all. If we fail to raise capital or enter into such agreements as and when needed, we may have to significantly delay, reduce or eliminate the development and commercialization of one or more of our product candidates or delay our pursuit of potential in licenses or acquisitions. Because of the numerous risks and uncertainties associated with product development, we are unable to predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability. Even if we are able to generate product sales, we may not become profitable. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be forced to reduce or terminate our operations. We expect that our existing cash and cash equivalents will be sufficient to fund our operating expenses and capital expenditure requirements for at least the next twelve months. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. Beyond that point, we will need to raise additional capital to finance our operations, which cannot be assured. Business Update Regarding COVID-19 The COVID-19 worldwide pandemic has presented substantial public health and economic challenges and continues to affect economies, financial markets and business operations around the world. The pandemic may continue to directly or indirectly affect the timeline for our manufacturing activities, planned IND submissions and clinical trials, including our global Phase 3 study of zilovertamab that we plan to initiate in the second quarter of 2022. The full extent to which the COVID-19 pandemic will continue to directly or indirectly impact the our business results of operations and financial condition, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain or treat it, the success or failure of ongoing vaccination programs worldwide, the emergence and spread of additional variants of COVID-19, as well as the economic impact on local, regional, national and international markets. Components of Results of Operations Grant Revenue Our grant revenue has been derived from a California Institute for Regenerative Medicine, or CIRM, grant subaward with UC San Diego and research and development grants from the National Institutes of Health, or NIH. In August 2017, CIRM awarded an $18.3 million grant to researchers at UC San Diego to advance our Phase 1/2 clinical trial evaluating zilovertamab in combination with ibrutinib for the treatment of patients with B-cell lymphoid malignancies, including MCL and CLL. Oncternal is conducting this study in collaboration with UC San Diego and estimates it will receive approximately $14.4 million in development milestones under research subaward agreements throughout the award project period, estimated to be from October 1, 2017 to March 31, 2022. In addition, we are committed to certain co-funding requirements and are required to provide UC San Diego progress and financial update reports throughout the award project period. We received subaward payments of $2.2 million and $1.4 million in the years ended December 31, 2021 and 2020, respectively. As of December 31, 2021, we believe we have met our obligations under the CIRM award and UC San Diego subawards. 110 In August 2021, the NIH awarded the Company two research and development grants for up to $2.2 million to support preclinical activities for the Company’s ONCT-216 and ONCT-534 programs, including $0.7 million payable to subawardees. Under the terms of the grant awards, the Company is entitled to receive reimbursement in arrears of incurring allowable expenditures. The earned NIH funds are non-refundable and the Company is required to provide periodic progress performance reports. During the year ended December 31, 2021, the Company received no award payments from the NIH and recorded $143,000 in grant revenue and unbilled receivables which has been included in prepaid and other assets. Operating Expenses Research and Development Research and development expenses consist primarily of costs incurred for the preclinical and clinical development of our product candidates, zilovertamab, ONCT-216, ONCT-808 and ONCT-534, which include: • • • • • expenses under agreements with third-party contract organizations, investigative clinical trial sites that conduct research and development activities on our behalf; costs related to develop and manufacture preclinical study and clinical trial material; salaries and employee-related costs, including stock-based compensation; costs incurred under our collaboration and third-party licensing agreements; and laboratory and vendor expenses related to the execution of preclinical and clinical trials. We accrue all research and development costs in the period for which they are incurred. Costs for certain development activities are recognized based on an evaluation of the progress to completion of specific tasks using information and data provided to us by our vendors, collaborators and third- party service providers. Advance payments for goods or services to be received in future periods for use in research and development activities are deferred and then expensed as the related goods are delivered and as services are performed. Any unearned advances would be refunded when known. We expect our research and development expenses to increase substantially for the foreseeable future as we: (i) continue to invest in developing our product candidates preclinically, advance preclinical assets into the clinic and as we begin to conduct larger global clinical trials, and (ii) invest in additional operational personnel to support our planned product development efforts. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials, especially for global studies. Our direct research and development expenses are tracked by product candidate and consist primarily of external costs, such as fees paid under third-party license agreements and to outside consultants, contract research organizations, or CROs, contract manufacturing organizations and research laboratories in connection with our preclinical development, process development, manufacturing and clinical development activities. We do not allocate employee costs and costs associated with our discovery efforts, laboratory supplies and facilities, including other indirect costs, to specific product candidates because these costs are deployed across multiple programs and, as such, are not separately classified. We use internal resources primarily to conduct our research as well as for managing our preclinical development, process development, manufacturing and clinical development activities. These employees work across multiple programs and, therefore, we do not track our costs by product candidate unless we can include them as subaward costs. We cannot determine with certainty the timing of initiation, the duration or the completion costs of current or future preclinical studies and clinical trials of our product candidates due to the inherently unpredictable nature of preclinical and clinical development, including any potential expanded dosing beyond the original protocols based in part on ongoing clinical success and the potential effects of the COVID-19 pandemic. Clinical and preclinical development timelines, the probability of success and development costs can differ materially from expectations. We anticipate that we will make determinations as to which product candidates to pursue and how much funding to direct to each product candidate on an ongoing basis in response to the results of ongoing and future preclinical studies and clinical trials, regulatory developments and our ongoing assessments of each product candidate’s 111 commercial potential. We will need to raise substantial additional capital in the future. In addition, we cannot forecast which product candidates may be subject to future collaborations, when such arrangements will be secured, if at all, and to what degree such arrangements would affect our development plans and capital requirements. General and Administrative General and administrative expenses consist primarily of personnel-related costs, insurance costs, facility costs and professional fees for legal, patent, consulting, investor and public relations, accounting and audit services. Personnel-related costs consist of salaries, benefits and stock-based compensation. We expect our general and administrative expenses will increase significantly as we: (i) incur additional costs associated with being a public company, including audit, legal, regulatory, and tax-related services associated with maintaining compliance with exchange listing and SEC requirements, director and officer insurance premiums, and investor relations costs, (ii) hire additional personnel, and (iii) protect our intellectual property. Other Income Paycheck Protection Program Loan During 2020, we received a $0.3 million loan under the Paycheck Protection Program, or PPP, a program implemented by the U.S. Small Business Administration, or SBA, under the Coronavirus Aid, Relief, and Economic Security Act, or the CARES Act. In December 2020, the underlying principal and interest were fully forgiven by the SBA and the Company has no further obligations thereunder. The loan forgiveness was recorded as other income in the consolidated statement of operations for the year ended December 31, 2020. Interest Income Interest income consists of interest earned on our cash equivalents, which consist of money market funds. Our interest income has not been significant due to low interest earned on invested balances. Results of Operations Comparison of the Years Ended December 31, 2021 and 2020 The following table summarizes our results of operations for the years ended December 31, 2021 and 2020 (in thousands): Grant revenues Operating expenses: Research and development General and administrative Total operating expenses Loss from operations Other income (expense): Other income Interest income Total other income (expense) Net loss Years Ended December 31, 2021 2020 Change $ 4,315 $ 3,375 $ 940 24,086 11,595 35,681 (31,366) — 33 33 (31,333) $ 12,544 8,373 20,917 (17,542) 301 16 317 (17,225) $ 11,542 3,222 14,764 (13,824) (301) 17 (284) (14,108) $ Grant Revenue Grant revenue for the year ended December 31, 2021 was $4.3 million, compared to $3.4 million for the year ended December 31, 2020. The increase of $0.9 million was primarily due to an increase in clinical and 112 manufacturing activities under the CIRM grant subaward and partially due to new operating activities under the NIH awards received in August 2021. Research and Development Expenses The following table summarizes our research and development expenses for the periods indicated (in thousands): Years Ended December 31, 2021 2020 Increase/ (Decrease) Zilovertamab ONCT-216 ONCT-808 ONCT-534 Unallocated research and development expenses Total research and development expenses $ $ 9,735 $ 3,048 2,300 303 8,700 24,086 $ 6,359 $ 2,340 27 275 3,543 12,544 $ 3,376 708 2,273 28 5,157 11,542 Research and development expenses for the years ended December 31, 2021 and 2020 were $24.0 million and $12.5 million, respectively, an increase of $11.5 million. The increase was due to: (i) a $6.3 million net increase in direct product candidate costs, and (ii) a $5.2 million increase in unallocated research and development expenses. Direct expenses for zilovertamab increased $3.4 million for the year ended December 31, 2021, compared to the year ended December 31, 2020, primarily due to the following partially offsetting factors: (i) a $0.2 million increase in preclinical costs, (ii) a $0.7 million increase in clinical trial costs primarily related to our ongoing Phase 1/2 clinical trial evaluating zilovertamab in combination with ibrutinib, (iii) a $2.2 million increase in manufacturing development costs related to the supply of clinical drug product, and (iv) a $0.3 million increase in license and milestone fees under the Regents License Agreement, as defined below. Direct expenses for ONCT-216 increased $0.7 million for the year ended December 31, 2021, compared to the year ended December 31, 2020, due primarily to the following offsetting factors: (i) a $0.2 million decrease in clinical trial costs related to our ongoing Phase 1/2 clinical trial of ONCT-216 in refractory Ewing sarcoma, and (ii) a $0.9 million increase in manufacturing development costs related to the supply of clinical drug product. Direct expenses for ONCT-808 increased $2.3 million for the year ended December 31, 2021, compared to the year ended December 31, 2020, primarily due to a: (i) $1.9 million increase in manufacturing and preclinical development costs and, (ii) $0.4 million increase in collaboration agreement costs. Direct expenses for ONCT-534 increased by a nominal amount for the year ended December 31, 2021, compared to the year ended December 31, 2020, primarily due to an increase in preclinical costs. Unallocated expenses increased $5.2 million for the year ended December 31, 2021, compared to the year ended December 31, 2020, primarily due to higher personnel costs, including higher non-cash share-based compensation expense of $2.6 million. General and Administrative Expenses General and administrative expenses for the years ended December 31, 2021 and 2020 were $11.6 million and $8.4 million, respectively, an increase of $3.2 million. The increase is primarily due to higher: (i) personnel and professional related costs of $2.5 million, including higher non-cash share-based compensation expense of $1.7 million, (ii) director’s and officer’s insurance costs of $0.4 million, and (iii) public company and other expenses of $0.3 million. Liquidity and Capital Resources 113 We have incurred losses and negative cash flows from operations since inception. As of December 31, 2021, we had an accumulated deficit of $114.1 million and anticipate that we will continue to incur net losses for the foreseeable future. As of December 31, 2021, we had $90.8 million in cash and cash equivalents and no debt. We believe we have sufficient cash to fund our projected operating requirements into mid-2023. Cash Flows The following table summarizes our net cash flow activity for each of the periods presented (in thousands): Net cash provided by (used in): Operating activities Financing activities Increase (decrease) in cash and cash equivalents $ $ (26,589) $ 617 (25,972) $ (17,495) 114,181 96,686 Years Ended December 31, 2021 2020 Operating Activities During the year ended December 31, 2021, net cash used in operating activities was $26.6 million, resulting from our net loss of $31.3 million and changes in our operating assets and liabilities of $1.3 million, partially offset by net non-cash charges of $6.0 million related to stock-based compensation and lease expense. The net loss of $31.3 million was driven by our ongoing clinical development activities partially offset by grant revenue. The $1.3 million change in operating assets and liabilities primarily consisted of the following activities, a: (i) $1.6 million decrease in deferred revenue, (ii) $0.9 million increase in prepaid and other assets and operating lease liability, and (iii) $1.2 million increase in accounts payable and accrued expenses. During the year ended December 31, 2020, operating activities used $17.5 million, resulting from our net loss of $17.2 million, which included net non-cash charges of $1.4 million related to stock-based compensation, lease expense, and forgiveness of the paycheck protection program loan, offset by a $1.7 million change in our operating assets and liabilities. The net loss of $17.2 million was driven by our ongoing clinical development activities partially offset by grant revenue. The $1.7 million change in operating assets and liabilities primarily consisted of the following partially offsetting activities: (i) a $2.0 million decrease in deferred revenue, (ii) a $0.7 million increase in prepaid and other assets and operating lease liability, and (iii) a $1.0 million increase in accounts payable and accrued expenses. Investing Activities No cash was used or provided by investing activities for the years ended December 31, 2021 and December 31, 2020. Financing Activities Financing activities provided net cash of $0.6 million for year ended December 31, 2021, which consisted of net proceeds from the exercise of common stock options and warrants. Financing activities provided net cash of $114.2 million for the year ended December 31, 2020, which primarily consisted of $113.9 million in net proceeds received from various public offerings. Operating Capital Requirements We anticipate that we will continue to incur losses for the foreseeable future, and we expect the losses to increase as we continue the research and development of, and seek regulatory approvals for, our product candidates and conduct additional research and development activities. Our product candidates have not yet achieved regulatory approval and we may not be successful in achieving commercialization of our product candidates. 114 We believe our existing cash and cash equivalents as of March 10, 2022 will be sufficient to fund our projected operating requirements into mid- 2023. However, our forecast of the period of time through which our financial resources will be adequate to support our planned operations is a forward- looking statement that involves risks and uncertainties, and actual results could vary materially. For example, the FDA or other regulatory authorities may require us to generate additional data or conduct additional preclinical studies or clinical trials, or may impose other requirements beyond those that we currently anticipate. Additionally, it is possible for a product candidate to show promising results in preclinical studies or in clinical trials, but fail to establish sufficient safety and efficacy data necessary to obtain regulatory approvals. As a result of these and other risks and uncertainties and the probability of success, the duration and the cost of our research and development activities required to advance a product candidate cannot be accurately estimated and are subject to considerable variation. We may encounter difficulties, complications, delays and other unknown factors and unforeseen expenses in the course of our research and development activities, any of which may significantly increase our capital requirements and could adversely affect our liquidity. We will require additional capital for the research and development of our product candidates, and we may be forced to seek additional funds sooner than expected to pursue our research and development activities. We expect to finance our capital requirements in the foreseeable future through a combination of the sale of public or private equity or debt securities, government funding, or other sources, including potentially collaborations, licenses and other similar arrangements. There can be no assurance that we will be able to obtain any sources of financing on acceptable terms, or at all. To the extent that we can raise additional funds by issuing equity securities, our stockholders may experience significant dilution. Any debt financing, if available, may involve restrictive covenants that may impact our ability to conduct our business. Any of these events could significantly harm our business, operations, financial condition and prospects. Our forecast of the period of time through which our existing cash and cash equivalents and investments will be adequate to support our operations is a forward-looking statement and involves significant risks and uncertainties. We have based this forecast on assumptions that may prove to be wrong, and actual results could vary materially from our expectations, which may adversely affect our capital resources and liquidity. We could utilize our available capital resources sooner than we currently expect. The amount and timing of future funding requirements, both near- and long-term, will depend on many factors, including, but not limited to: • • • • • • • • • • • • the costs incurred as a result of the COVID-19 pandemic, including clinical trial delays; the type, number, scope, progress, expansions, results, costs and timing of our clinical trials of zilovertamab and ONCT-216, and preclinical studies or clinical trials of our ROR1 CAR-T and DAARI product candidates or additional indications of our current product candidates as well as other product candidates that we may choose to pursue in the future; the costs and timing of manufacturing for our product candidates, including commercial manufacturing if any product candidate is approved; the costs of obtaining ibrutinib, for which we currently obtain supply at no cost under our clinical supply agreement with Pharmacyclics, to conduct our clinical trials of zilovertamab; the costs and capacity for CAR-T development and lentivirus manufacturing; the costs, timing and outcome of seeking and obtaining worldwide regulatory approvals for our product candidates; the costs of obtaining, maintaining and enforcing our patents and other intellectual property rights; the costs associated with hiring additional personnel, CROs and consultants as our preclinical and clinical activities increase; our ability to achieve sufficient market acceptance, adequate coverage and reimbursement from third-party payors and adequate market share and revenue for any approved products; the terms and timing of establishing and maintaining collaborations, licenses and other similar arrangements, including milestone or other payments under our existing in-license agreements and any in-license agreements that we may enter into in the future; costs associated with any products or technologies that we may in-license or acquire; and the cost and timing of establishing sales, marketing, manufacturing and distribution capabilities for, and the pricing and reimbursement of, any products for which we may receive regulatory approval. If we cannot continue or expand our research and development operations, or otherwise capitalize on our business opportunities, because we lack sufficient capital, our business, operations, financial condition and prospects could be materially adversely affected. 115 In December 2021, we entered into the ATM Sales Agreement, pursuant to which we are able to offer and sell, from time to time, shares of our common stock having an aggregate offering price of up to $50.0 million. We have no obligation to sell any shares under the Sales Agreement and may at any time suspend solicitation and offers under the Sales Agreement. Through December 31, 2021, we have not sold any shares under the Sales Agreement. Under current SEC regulations, if at any time our public float is less than $75.0 million, and for so long as our public float remains less than $75.0 million, the amount we can raise through primary public offerings of securities in any twelve-month period using shelf registration statements is limited to an aggregate of one-third of our public float, which is referred to as the baby shelf rules. As of December 31, 2021, our calculated public float exceeded $75.0 million. In April 2021, our Form S-3 registration statement became effective. Future sales of our common stock, if any, will depend on a variety of factors including, but not limited to, the expected timing for achieving key milestones, including initiating, completing and announcing results of clinical trials of zilovertamab and ONCT-216 and announcing the first-in-human dosing of our CAR-T product candidate targeting ROR-1, currently in preclinical development, prevailing market conditions, the trading price of our common stock and our capital needs. There can be no assurance that we will be successful in consummating future sales of our securities based on prevailing market conditions or in the quantities or at the prices that we deem appropriate. Contractual Obligations and Commitments We are party to a number of license agreements, pursuant to which we have payment obligations that are contingent upon future events such as our achievement of specified development, regulatory and commercial milestones and are required to make royalty payments in connection with the sale of products developed under those agreements. As of December 31, 2021, we were unable to estimate the timing or likelihood of achieving the milestones or making future product sales. See Notes 3 and 4 to our consolidated financial statements included elsewhere in this Annual Report for a description of these agreements. We enter into contracts in the normal course of business with clinical trial sites and clinical supply manufacturers and with vendors for preclinical studies, research supplies and other services and products for operating purposes. These contracts generally provide for termination after a notice period, and, therefore, are cancelable contracts. Critical Accounting Policies & Estimates Management’s discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). The preparation of the financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical trends and other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Our significant accounting policies are described in more detail in Note 1, “Description of Business, Basis of Presentation and Summary of Significant Accounting Policies,” in the notes to our consolidated financial statements as of December 31, 2021 and 2020 and for each of the years ended December 31, 2021 and 2020, appearing elsewhere in this Annual Report. However, we believe that the following accounting policies are the most critical for fully understanding and evaluating our financial condition and results of operations. Research and Development Expenses and Accruals As part of the process of preparing our consolidated financial statements, we are required to estimate our accrued expenses. This process involves reviewing quotations and contracts, identifying services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of the actual cost. Certain service providers invoice us in arrears for services performed or when contractual milestones are met. We make estimates of our accrued expenses as of each balance sheet date in our financial statements based on facts and circumstances known 116 to us at that time. We periodically confirm the accuracy of our estimates with the service providers and make adjustments if necessary. Examples of estimated accrued research and development expenses include fees paid to: (i) CROs and other third parties in connection with clinical studies and preclinical development activities; (ii) investigative sites in connection with clinical studies; and (iii) third parties related to product manufacturing, development and distribution of clinical supplies. We base our expenses related to CROs on our estimates of the services received and efforts expended pursuant to quotes and contracts with CROs that conduct research and development on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the research and development expense. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or prepaid accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and could result in us reporting amounts that are too high or too low in any particular period. Revenue Recognition We generate revenue from certain grant awards or a subaward (the “Grant Awards”) (see Note 4), which provide us with payments in return for certain research and development activities over a contractually defined period. Revenue from Grant Awards is recognized in the period during which the related qualifying services are rendered and costs are incurred, provided that the applicable conditions under the Grant Awards have been met. The Grant Awards are on a best-effort basis and do not require scientific achievement as a performance obligation. The Grant Awards are nonrefundable. The costs associated with the Grant Awards are expensed as incurred and reflected as a component of research and development expense in the accompanying consolidated statements of operations. Funds received from the Grant Awards are recorded as revenue as we are the principal participant in the arrangement because the activities under the Grant Awards are part of our development programs. In those instances where we first receive consideration in advance of providing underlying services, we classify such consideration as deferred revenue until (or as) we provide the underlying services. In those instances where we first provide the underlying services prior to receipt of consideration, we record a grant receivable. Item 7A. Quantitative and Qualitative Disclosures About Market Risk. We are a smaller reporting company, as defined by Rule 12b-2 of the Exchange Act, and are not required to provide the information required under this item. Item 8. Financial Statement and Other Supplementary Information. The Consolidated Financial Statements and supplementary data of Oncternal Therapeutics, Inc. required by this Item are described in Item 15 of this Annual Report and are presented beginning on page F-1. 117 Report of Independent Registered Public Accounting Firm Shareholders and Board of Directors Oncternal Therapeutics, Inc. San Diego, California Opinion on the Consolidated Financial Statements We have audited the accompanying consolidated balance sheets of Oncternal Therapeutics, Inc. (the “Company”) as of December 31, 2021 and 2020, the related consolidated statements of operations, stockholders’ equity, and cash flows for the years then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and 2020, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America. Basis for Opinion These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s 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 the 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 opinions on the critical audit matter or on the accounts or disclosures to which it relates. Clinical Trial Accruals As described in Notes 1 and 2 to the consolidated financial statements, the Company has recorded $0.5 million for accrued clinical trial expenses for the estimated costs incurred but not yet billed or paid as of December 31, 2021. When payment terms under the related contracts do not align with the pattern of costs incurred, the Company is required to make estimates of the outstanding obligations as of period end. When evaluating the adequacy of the accrued clinical trial liabilities, the Company analyzes progress of the services, including the phase or completion of events, invoices received and contracted costs, which could involve significant judgements, estimates, and specialized knowledge. F-1 We identified clinical trial accruals as a critical audit matter due to the application of significant management judgement over the estimate of services provided as of year-end. Specifically, the amount of accrued clinical trial expenses recognized is sensitive to the availability of information to make the estimate, including the estimate of the progress of the clinical trial and the level of effort expended including patient enrollment and follow-up activity as of the balance sheet date and the associated cost of such services. Auditing these elements involved especially subjective auditor judgment due to the nature of the audit evidence available to address these matters. The primary procedures we performed to address this critical audit matter included: • • • Reviewing the Company’s contractual agreements with third parties and any change orders to assess the impact to the amounts recorded including changes in scope and timing. Testing clinical accrual cutoff and evaluating the completeness and valuation of clinical accruals by comparing invoices received by the Company subsequent to December 31, 2021 to the amounts recognized by the Company as of that date. Testing clinical accrual for completeness and accuracy by confirming amounts due at December 31, 2021 directly with clinical research organizations (CROs) including total expenses incurred for all services provided by the CRO during 2021. /s/ BDO USA, LLP We have served as the Company's auditor since 2016.

F-6 Oncternal Therapeutics, Inc. Notes to Consolidated Financial Statements 1. Description of Business, Basis of Presentation and Summary of Significant Accounting Policies Description of Business Oncternal Therapeutics, Inc. (the “Company,” “Oncternal,” or the “combined company”), formerly known as GTx, Inc., was incorporated in Tennessee in September 1997 and reincorporated in Delaware in 2003 and is based in San Diego, California. The Company is a clinical-stage biopharmaceutical company focused on the development of novel oncology therapies for the treatment of cancers with critical unmet medical need. The Company’s clinical pipeline includes zilovertamab, a humanized monoclonal antibody that binds to ROR1 (Receptor-tyrosine kinase-like Orphan Receptor 1), and ONCT-216, a small molecule inhibiting the biological activity of ETS-family transcription factor oncoproteins. The Company is also developing ONCT-808, a CAR-T (chimeric antigen receptor T-cells) product candidate that targets ROR1 and ONCT-534, a dual-action androgen receptor inhibitor product candidate for the treatment of castration-resistant prostate and other androgen receptor-driven cancers. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Oncternal Oncology, Inc. and Oncternal, Inc. All intercompany accounts and transactions have been eliminated in the preparation of the consolidated financial statements. Liquidity and Going Concern From inception, the Company has devoted substantially all of its efforts to drug discovery and development and conducting preclinical studies and clinical trials. The Company has a limited operating history and the sales and income potential of the Company’s business and market are unproven. Successful transition to attaining profitable operations is dependent upon achieving a level of revenues adequate to support the Company’s cost structure. As of December 31, 2021, the Company had $90.8 million in cash and cash equivalents and no debt. The Company believes it has sufficient cash to fund its projected operating requirements for at least twelve months from the date of issuance. However, the Company has experienced net losses and negative cash flows from operating activities since its inception and has an accumulated deficit of $114.1 million as of December 31, 2021. The Company expects to continue to incur net losses for the foreseeable future and believes it will need to raise substantial additional capital to accomplish its business plan over the next several years. The Company plans to continue to fund its losses from operations and capital funding needs through a combination of public or private equity or debt offerings or other sources, including potential collaborations, strategic alliances and other similar licensing arrangements in both the short term and long term. If the Company is unable to secure adequate additional funding, the Company may be forced to make reductions in spending, including potentially delaying, scaling back or eliminating certain of our pipeline development programs, extend payment terms with suppliers, or liquidate assets where possible. Any of these actions could materially harm the Company’s business, results of operations and future prospects. The Company currently has capacity to issue $50.0 million of additional shares of common stock under its recently established and unused ATM program. There can be no assurance that the Company will be able to sell any shares of its common stock under the ATM Program or regarding the price at which it will be able to sell any such shares, and any sales of shares of its common stock under the ATM Program may be at prices that result in additional dilution to existing stockholders of the Company. The Company's ability to obtain additional financing (including through collaborating and licensing arrangements) will depend on a number of factors, including, among others, its ability to generate positive data from its clinical trials and preclinical studies, the condition of the capital markets and the other risks, many of which are dependent on factors outside of its control. There can be no assurance as to the availability or terms upon which such financing and capital might be available in the future. F-7 Use of Estimates The Company’s consolidated financial statements are prepared in accordance with GAAP. The preparation of the Company’s consolidated financial statements and accompanying notes requires it to make estimates and assumptions that impact the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities. Significant estimates consist of those used to determine the fair value of the Company’s stock-based awards, and those used to determine grant revenue and accruals for research and development costs. Although these estimates are based on the Company’s knowledge of current events and actions it may undertake in the future, actual results may ultimately materially differ from these estimates and assumptions. Cash and Cash Equivalents The Company considers all highly liquid investments with maturities of three months or less when purchased to be cash equivalents. Cash and cash equivalents include cash in readily available checking accounts and money market accounts. Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits. The Company has not experienced any losses in such accounts and believes it is not exposed to significant risk on its cash balances due to the financial position of the depository institution in which those deposits are held. Additionally, the Company established guidelines regarding approved investments and maturities of investments, which are designed to maintain safety and liquidity. Patent Costs Costs related to filing and pursuing patent applications are recorded as general and administrative expense and expensed as incurred since recoverability of such expenditures is uncertain. Research and Development Expenses and Accruals Research and development expenses consist of costs incurred for the Company’s own and for sponsored and collaborative research and development activities. Research and development costs are expensed as incurred and include manufacturing process development costs, manufacturing costs, costs associated with preclinical studies and clinical trials, regulatory and medical affairs activities, quality assurance activities, salaries and benefits, including stock-based compensation, fees paid to third-party consultants, license fees and overhead. The Company has entered into various research and development contracts with research institutions, clinical research organizations, clinical manufacturing organizations and other companies. Payments for these activities are based on the terms of the individual agreements, which may differ from the pattern of costs incurred, and payments made in advance of performance are reflected in the accompanying consolidated balance sheets as prepaid and other assets or accrued liabilities. The Company records accruals for estimated costs incurred for ongoing research and development activities. When evaluating the adequacy of the accrued liabilities, the Company analyzes progress of the services, including the phase or completion of events, invoices received and contracted costs. Significant judgments and estimates may be made in determining the prepaid or accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates. As of December 31, 2021, the Company’s clinical trial accrual balance of $0.5 million is included in accrued liabilities. The Company’s related clinical trial expenses are included in research and development expenses of $24.1 million and $12.5 million at December 31, 2021 and December 31, 2020, respectively. F-8 Fair Value Measurements The accounting guidance defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or non-recurring basis. Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the accounting guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1: Observable inputs such as quoted prices in active markets. Level 2: Inputs, other than the quoted prices in active markets that are observable either directly or indirectly. Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. The carrying amounts of the Company’s current financial assets and liabilities are considered to be representative of their respective fair values because of the short-term nature of those instruments. The Company has no financial assets or liabilities measured at fair value on a recurring basis. No transfers between levels have occurred during the periods presented. Revenue Recognition The Company generates revenue from certain grant awards or a research subaward (the “Grant Awards”)(see Note 4), which provides the Company with payments in return for certain research and development activities over a contractually defined period. Revenue from such Grant Awards is recognized in the period during which the related qualifying services are rendered and costs are incurred, provided that the applicable conditions under the Grant Awards have been met. The Grant Awards are on a best-efforts basis and do not require scientific achievement as a performance obligation. The Grant Awards are non- refundable. The costs associated with the Grant Awards are expensed as incurred and reflected as a component of research and development expense in the accompanying consolidated statements of operations. Funds received from the Grant Awards are recorded as revenue as the Company is the principal participant in the arrangement because the activities under the Grant Awards are part of the Company’s development programs. In those instances where the Company first receives consideration in advance of providing underlying services, the Company classifies such consideration as deferred revenue until (or as) the Company provides the underlying services. In those instances where the Company first provides the underlying services prior to its receipt of consideration, the Company records a grant receivable. At December 31, 2021 and 2020, the Company had a grant receivable of $0.4 million and deferred grant revenue of $1.6 million, respectively. Stock-Based Compensation Stock-based compensation expense represents the fair value of equity awards, on the grant date, recognized in the period using the Black- Scholes option pricing model. The Company recognizes expense for awards with graded vesting schedules over the requisite service period of the awards (usually the vesting period) on a straight-line basis. For equity awards for which vesting is subject to performance-based milestones, the expense is recorded over the remaining service period after the point when the achievement of the milestone is probable. The Company recognizes forfeitures for all awards as such forfeitures occur. Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have F-9 been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the financial statements 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 effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The Company recognizes net deferred tax assets to the extent that the Company believes these assets are more likely than not to be realized. In making such a determination, management considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If management determines that the Company would be able to realize its deferred tax assets in the future in excess of their net recorded amount, management would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. Segment Reporting Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker in making decisions regarding resource allocation and assessing performance. The Company views its operations and manages its business in one operating segment in the United States. Net Loss Per Share Basic net loss per share is computed by dividing the net loss by the weighted-average number of common shares outstanding for the period, without consideration for potentially dilutive securities and adjusted for the weighted-average number of common shares outstanding that are subject to repurchase. The Company has excluded weighted-average shares subject to repurchase of 7,000 shares and 25,000 shares from the weighted-average number of common shares outstanding for the years ended December 31, 2021 and 2020, respectively. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock and dilutive common stock equivalents outstanding for the period determined using the treasury-stock and if-converted methods. For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding as inclusion of the potentially dilutive securities would be antidilutive. Potentially dilutive securities not included in the calculation of diluted net loss per share, because to do so would be anti-dilutive, are as follows (in common stock equivalent shares; in thousands): Warrants to purchase common stock Common stock options Common stock subject to repurchase Recently Adopted Accounting Pronouncements ASU 2021-10 December 31, 2021 2020 4,235 6,445 — 10,680 5,032 2,226 15 7,273 In November 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2021-10, Government Assistance (Topic 832) Disclosures by Business Entities about Government Assistance (“ASU 2021-10”). The FASB issued the ASU to improve transparency by requiring business entities to disclose information about certain types of government assistance they receive in the notes to the financial statements. The disclosure requirements in ASU 2021-10 only apply to transactions with a government that are accounted for by analogizing to either a grant model (for example, in International Accounting Standard (IAS) 20, Accounting for Government Grants and Disclosure of Government Assistance), or a contribution model. ASU 2021-10 requires the entity to disclose the nature and significant terms and conditions of the transaction, accounting policies used to account for the transaction, and line items in the financial statements affected by the transaction. ASU 2021-10 is effective for annual periods beginning F-10 after December 15, 2021. Early adoption is permitted, including adoption in an interim period. The Company elected to early adopt ASU 2021-10 under the prospective method of transition effective January 1, 2021, and determined that there was no cumulative effect to be recognized upon early adoption. In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. Specifically, ASU 2020-06 simplifies accounting for the issuance of convertible instruments by removing major separation models required under current GAAP. In addition, the ASU removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and simplifies the diluted earnings per share (EPS) calculation in certain areas. ASU 2020-06 will be effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted, beginning in fiscal years which begin after December 15, 2020. The FASB has specified that an entity should adopt the guidance as of the beginning of its annual fiscal year. The Company adopted this standard effective January 1, 2021, and the adoption had no impact on the consolidated financial statements. Accounting Standards Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Statements (Topic 362), which intends to improve financial reporting by requiring earlier recognition of credit losses on certain financial assets, such as available-for-sale debt securities. Subsequent to the issuance of ASU 2016-13, the FASB issued several additional ASUs to clarify implementation guidance, provide narrow- scope improvements and provide additional disclosure guidance. In November 2019, the FASB issued an amendment making this ASU effective for fiscal years beginning after December 15, 2022 for smaller reporting companies. The Company was a smaller reporting company at the determination date, and therefore the new standard will be effective for the Company on January 1, 2023. The Company is currently evaluating the potential impact that the adoption of ASU 2016-13 may have on its consolidated financial statements and related disclosures. In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt-Modifications and Extinguishments (Subtopic 470-50), Compensation-Stock Compensation (Topic 718), and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options, which intends to clarify and reduce diversity in an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options (for example, warrants) that remain equity classified after modification or exchange. The guidance is effective for fiscal years beginning after December 15, 2021, including interim periods therein, and early adoption is permitted. The Company is currently evaluating the potential impact that the adoption of ASU 2021-04 may have on its consolidated financial statements and related disclosures. 2. Balance Sheet Details Accrued liabilities consist of the following (in thousands): Research and development Clinical trials Legal fees Unvested share liability Compensation Other December 31, 2021 2020 $ $ 779 $ 518 154 — 1,955 25 3,431 $ 412 980 77 10 1,528 35 3,042 F-11 3. Commitments, Contingencies and Related Party Transactions Lease Rent expense was $0.2 million for the years ended December 31, 2021 and 2020. On May 22, 2019, the Company entered into an office sublease agreement for 4,677 square feet in San Diego, California (“San Diego Lease”) which expired on March 31, 2021. On March 17, 2021, the Company entered into a direct lease with the landlord for the same facility (the “San Diego Lease”) which expires on May 31, 2022. Base rent under the San Diego Lease is approximately $77,000 for the remainder of the lease term and the monthly rent expense is being recognized on a straight-line basis over the lease term. The San Diego Lease is included in the accompanying consolidated balance sheet at the present value of the lease payments. As the San Diego Lease does not have an implicit interest rate, the present value reflects a 10.0% discount rate which is the estimated rate of interest that the Company would have to pay in order to borrow an amount equal to the lease payments on a collateralized basis over a similar term and in a similar economic environment. As of December 31, 2021, the Company has recognized a net operating lease right-of-use asset and a lease liability of $75,000 that matures in May 2022, which has a weighted average remaining lease term of 0.42 years. Related Party Transactions In January 2019, the Company engaged Newfront Insurance as its primary insurance broker. The son of Richard Vincent, the Company’s Chief Financial Officer, acted as the Company’s agent at Newfront Insurance. During the years ended December 31, 2021 and 2020, the Company paid total related policy premiums of $1.8 million and $1.4 million, respectively, for which Mr. Vincent’s son received a commission of $0.1 million. Effective in September 2019, the Company and Shanghai Pharmaceutical (USA) Inc. (“SPH USA”) entered into a Materials Supply and Services Agreement (“SPH USA Services Agreement”), pursuant to which the Company and SPH USA will execute various statements of work for the transfer to SPH USA of key reagents and other materials, and for the supply of certain services by the Company to SPH USA, as contemplated under and in furtherance of the License and Development Agreement between the Company and SPH USA effective as of November 2018. During the year ended December 31, 2021, the Company recorded amounts receivable from SPH USA related to statements of work totaling $0.4 million (see Note 4). SPH USA is the Company’s largest stockholder and an affiliate of two of the Company’s directors. In connection with the securities purchase agreements and underwritten offering, other investors included individuals or entities affiliated with David F. Hale, SPH USA, Daniel L. Kisner and Michael G. Carter (see Note 6). F-12 4. License, Collaboration, Research Subaward Agreement and CVR Agreements Georgetown University (“Georgetown”) In March 2014, the Company entered into an Exclusive License Agreement (the “Georgetown License Agreement”) with Georgetown, pursuant to which the Company: (i) licensed the exclusive worldwide right to patents and technologies for the development and commercialization of certain product candidates targeting EWS-FLI1 as an anti-tumor therapy for therapeutic, diagnostics, or research tool purposes, (ii) is solely responsible for all development and commercialization activities and costs, and (iii) is responsible for all costs related to the filing, prosecution and maintenance of the licensed patent rights. Under the terms of the Georgetown License Agreement, commencing in 2015, the Company: (i) shall pay and has paid an annual license maintenance fee of $10,000 until the first commercial sale occurs, (ii) is required to make up to $0.2 million in aggregate milestone payments upon the achievement of certain regulatory milestones, and (iii) will be required to pay low single digit royalties based on annual net product sales. The Company accounted for the licensed technology as an asset acquisition because it did not meet the definition of a business. All milestone payments under the Georgetown License Agreement will be recognized as research and development expense upon completion of the required events, as the triggering events are not considered to be probable until they are achieved. As of December 31, 2021, the Company had not triggered or made any milestone payments under the Georgetown License Agreement. The Georgetown License Agreement may be terminated by either party upon material breach or may be terminated by the Company as to one or more countries with 90 days written notice of termination. The term of the Georgetown License Agreement will continue until the expiration of the last valid claim within the patent rights covering the product. Georgetown may terminate the agreement in the event: (i) the Company fails to pay any amount and fails to cure such failure within 30 days after receipt of notice, (ii) the Company defaults in its obligation to obtain and maintain insurance and fails to remedy such breach within 60 days after receipt of notice, or (iii) the Company declares insolvency or bankruptcy.

The University of Texas MD Anderson Cancer Center (“MD Anderson”) In December 2014, the Company entered into a collaboration agreement (as amended, the “Collaboration”) with MD Anderson, which provides for the conduct of preclinical and clinical research for ONCT-216 in exchange for certain program payments. If MD Anderson successfully completes all the requirements of the Collaboration in full and the program is successfully commercialized, the Company will be required to pay aggregate milestone payments of $1.0 million based on net product sales. In July 2020 and September 2021, the Company entered into two research agreements with MD Anderson for certain services up to an aggregate cost of $0.8 million. The amount recorded as research and development expense for the year ended December 31, 2021 and 2020 was $0.1 million. F-13 Agreements with the Regents of the University of California (the “Regents”) In March 2016, and as amended and restated in August 2018, and as amended in March and May 2019 and February 2021, the Company entered into a license agreement (as amended and restated, the “Regents License Agreement”) for the development, manufacturing and distribution rights related to the development and commercialization of ROR1 related naked antibodies, antibody fragments or synthetic antibodies, and genetically engineered cellular therapy. The Regents License Agreement provides for the following: (i) in May 2016, an upfront license fee of $0.5 million was paid and 107,108 shares of common stock were issued, (ii) $25,000 in annual license maintenance fees commencing in 2017, (iii) reimbursement of certain annual patent costs, (iv) certain development and regulatory milestones aggregating from $10.0 million to $12.5 million, on a per product basis, (v) certain worldwide sales milestones based on achievement of tiered revenue levels aggregating $75.0 million, (vi) low single-digit royalties, including potential future minimum annual royalties, on net sales of each target, and (vii) minimum diligence to advance licensed assets consisting of at least $1.0 million in development spend annually through 2021.

Related qualifying subaward costs for the years ended December 31, 2021 and 2020 were $8.8 million and $5.2 million, respectively. As of December 31, 2021, the Company believes it has met its obligations under the CIRM award and UC San Diego subawards. In October 2017, CIRM awarded a $5.8 million grant to the researchers at the University of California San Diego School of Medicine (“UC San Diego”) to develop a novel anti-cancer stem cell targeted therapy for patients with advanced solid and hematological malignancies. In connection with such CIRM award, the Company agreed to provide up to $1.0 million in contingency funds if required during the grant period. The Company recorded no research and development expense, and no contingency funds have been provided under such CIRM award for the years ended December 31, 2021 and 2020. The grant expired in 2021 and the Company believes there are no obligations as of December 31, 2021. The National Institutes of Health (“NIH”) Grant Awards In August 2021, the NIH awarded the Company two research and development grants for up to $2.2 million to support preclinical activities for the Company’s ONCT-216 and ONCT-534 programs, including $0.7 million payable to subawardees. Under the terms of the grant awards, the Company is entitled to receive reimbursement in arrears of incurring allowable expenditures. The earned NIH funds are non-refundable and the Company is required to provide periodic progress performance reports. During the year ended December 31, 2021, the Company received no award payments from the NIH and recorded $143,000 in grant revenue and unbilled receivables which has been included in prepaid and other assets. Clinical Trial and Supply Agreement In April 2018, and as amended in August 2019, the Company entered into a Clinical Trial and Supply Agreement with Pharmacyclics, LLC, an AbbVie Company (“Pharmacyclics”) to supply ibrutinib for the Company’s Phase 1/2 clinical trial evaluating zilovertamab in combination with ibrutinib. Such agreement does not bear any upfront costs, inventory purchase costs, milestone or royalty payment commitments or other financial obligations. SPH USA, a Related Party License and Development Agreement (“LDA”) In November 2018, and as amended in August 2020, the Company entered into the LDA with SPH USA for: (i) the territory of the People’s Republic of China, Hong Kong, Macau, and Taiwan (“Greater China”), and (ii) rights to manufacture, develop, market, distribute and sell all of the Company’s product candidates under the Georgetown License Agreement and the Regents License Agreement (exclusive to Greater China only).

Contingent Value Rights Agreement (“CVR Agreement”) Pursuant to the GTx merger agreement entered into in June 2019 (the “Merger”), the Company, a representative of holders of the CVRs, and Computershare, Inc. as rights agent entered into the CVR Agreement. Pursuant to the CVR Agreement, the Company’s stockholders of record as of immediately prior to the Merger received one CVR for each share of the Company’s common stock held immediately prior to the Merger. As amended on November 1, 2021, the CVR Agreement entitles holders of CVRs to receive: (i) 50% of certain net proceeds received by the Company during the 15-year period after the closing of the Merger (the “CVR Term”) from a transaction, if any, resulting in the grant, sale, or transfer of DAARI technology to a third party that occurs during the 10-year period after the closing of the Merger (or in the 11th year if based on a term sheet approved during the initial 10-year period); and (ii) 5% of net sales of products by Parent or its affiliates during the CVR Term incorporating the DAARI technology. As of December 31, 2021, no transactions or net sales relating to the DAARI technology had occurred. 5. Debt Paycheck Protection Program Loan Payable In May 2020, the Company received a $0.3 million unsecured loan, bearing interest at 1%, pursuant to the Paycheck Protection Program (the “PPP”), a program implemented by the U.S. Small Business Administration (the “SBA”) under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) (the “PPP Loan”). In December 2020, the underlying principal and interest were fully forgiven by the SBA and the Company has no further obligations thereunder. The loan forgiveness was recorded as other income of $0.3 million in the consolidated statement of operations. 6. Stockholders’ Equity Amended and Restated Articles of Incorporation On May 25, 2021, the Company’s certificate of incorporation was amended and restated to authorize 120,000,000 shares of common stock and 5,000,000 shares of undesignated preferred stock, each with a par value of $0.001 per share.

In addition, the Company issued warrants to purchase 145,733 shares of common stock at an exercise price of $2.625 per share to Wainwright as part of its compensation, which warrants were immediately exercisable upon issuance and terminate on August 27, 2025. An investor participating in the transaction included Michael G. Carter, a member of the Company’s board of directors.

Common Stock Warrants A summary of warrant activity and changes in warrants outstanding is presented below: Balance Outstanding - December 31, 2019 Issued Exercised Balance Outstanding - December 31, 2020 Issued Exercised Balance Outstanding - December 31, 2021 Number of Shares Underlying Warrants Weighted-Average Exercise Price per Share 841,424 4,265,198 (74,781) 5,031,841 — (796,931) 4,234,910 $ $ $ $ $ $ $ 37.97 3.47 3.22 9.25 — 2.56 10.50 Weighted-Average Remaining Contractual Term 2.75 — 4.40 — — 3.31 As of December 31, 2021 and 2020, all warrants met the criteria for classification in stockholders’ equity. F-17 Equity Incentive Plans Contemporaneous with the Merger closing: (i) Private Oncternal’s 2015 Equity Incentive Plan, as amended (the “2015 Plan”) was assumed by the Company, and (ii) the Company adopted the 2019 Incentive Award Plan (“2019 Plan”) under which the sum of: (a) 1,678,571 shares of common stock, (b) 275,579 shares of common stock previously outstanding under the GTx 2013 Equity Incentive Plan that were cancelled became available for issuance under the 2019 Plan, and (c) an annual increase on the first day of each calendar year beginning January 1, 2020, and ending on and including January 1, 2029, equal to the lesser of (A) 5% of the aggregate number of shares of common stock outstanding on the final day of the immediately preceding calendar year and (B) such smaller number of shares of common stock as is determined by the Board, are reserved for issuance. At December 31, 2021, 1,842,432 shares remain available for future issuance under the 2019 Plan and Inducement Plan (as defined below). In July 2015, Private Oncternal adopted the 2015 Plan which provided for the issuance of up to 631,120 shares of common stock for incentive stock options, non-statutory stock options, restricted stock awards, restricted stock unit awards and other stock awards to its employees, members of its board of directors and consultants. In general, the options issued under the 2015 Plan expire ten years from the date of grant and vest over a four-year period. Certain grants vest based on the achievement of development or regulatory milestones. The 2015 Plan was terminated as to new grants in June 2019. The 2019 Plan provides for the issuance of shares of common stock for incentive stock options, non-statutory stock options, restricted stock awards, restricted stock unit awards and other stock awards to its employees, members of its board of directors and consultants. In general, the stock options issued under the 2019 Plan expire ten years from the date of grant and vest over a four-year period. Certain stock option grants vest based on the achievement of development or regulatory milestones. The 2019 Plan allows for the early exercise of all stock option grants if authorized by the board of directors at the time of grant. On February 11, 2021, the Company’s board of directors adopted the 2021 Employment Inducement Incentive Award Plan (the “Inducement Plan”). The Inducement Plan is a non-shareholder approved stock plan adopted pursuant to the “inducement exception” provided under Nasdaq listing rules. The Inducement Plan is used exclusively for the issuance of non-statutory stock options to certain new hires who satisfied the requirements to be granted inducement grants under Nasdaq rules as an inducement material to the individual’s entry into employment with the Company. The terms of the Inducement Plan are substantially similar to the terms of our 2019 Plan. As amended on May 25, 2021 and December 16, 2021, the Company has reserved 2,800,000 shares of common stock under the Inducement Plan. A summary of the Company’s stock option activity under the 2015 Plan, 2019 Plan and Inducement Plan is as follows: Outstanding at December 31, 2020 Granted Cancelled Exercised Outstanding at December 31, 2021 Vested and exercisable at December 31, 2021 Weighted- Average Exercise Price Weighted- Average Remaining Contractual Term (in years) Aggregate Intrinsic Value 4.08 5.78 5.46 3.84 5.28 3.92 8.7 $ 613,190 6.8 $ 488,187 Number of Options 2,107,625 $ 4,884,800 $ (439,684) $ (107,997) $ 6,444,744 $ 1,440,122 $ The weighted average grant date fair value per share of option grants for the years ended December 31, 2021 and 2020 was $4.35 and $2.53 per share, respectively. The intrinsic value is calculated as the difference between the fair value of the Company’s common stock at the time of the option exercise and the exercise price of that stock option. The aggregate intrinsic value of stock options exercised during the years ended December 31, 2021 and 2020 was $419,755 and $10,413. F-18 Stock-Based Compensation Expense The weighted-average assumptions used in the Black-Scholes option pricing model to determine the fair value of stock option grants were as follows: Risk-free interest rate Expected volatility Expected term (in years) Expected dividend yield Years Ended December 31, 2021 2020 0.9% 92.8% 6.2 —% 0.7% 91.6% 6.7 —% Expected volatility. The expected volatility assumption is based on volatilities of a peer group of similar companies whose share prices are publicly available. The peer group was developed based on companies in the life sciences industry. The Company will continue to apply this process until a sufficient amount of historical information regarding the volatility of its own stock price becomes available. Expected term. The expected term represents the period of time that options are expected to be outstanding. Because Private Oncternal did not have historical exercise behavior, it determined the expected term assumption using the simplified method for employees, which is an average of the contractual term of the option and its vesting period. The expected term for nonemployee options is generally the remaining contractual term. Risk-free interest rate. The risk-free interest rate is based on the implied yield on the U.S. Treasury securities with a maturity date similar to the expected term of the associated stock option award. Expected dividend yield. The Company bases the expected dividend yield assumption on the fact that it has never paid cash dividends and has no present intention to pay cash dividends and, therefore, used an expected dividend yield of zero. Stock-based compensation expense recognized for all equity awards has been reported in the statements of operations as follows (in thousands): Research and development General and administrative Years Ended December 31, 2021 2020 $ $ 3,136 $ 2,739 5,875 $ 544 1,012 1,556 At December 31, 2021, the total compensation cost related to nonvested awards not yet recognized was $17.4 million and the weighted-average period over which it is expected to be recognized was 3.2 years. Common Stock Reserved for Future Issuance Common stock reserved for future issuance is as follows (in thousands): Common stock warrants Common stock options issued and outstanding Common stock available for issuance under equity plans F-19 December 31, 2021 2020 4,235 6,445 1,842 12,522 5,032 2,226 938 8,196 7. COVID-19 Pandemic and CARES Act A novel strain of coronavirus (SAR-CoV-2) causing a severe respiratory disease (“COVID-19”), was declared a global pandemic by the World Health Organization in March 2020. COVID-19 has presented substantial public health and economic challenges and is affecting economies, financial markets and business operations around the world. International and U.S. governmental authorities in impacted regions have taken actions in an effort to slow the spread of COVID-19, including issuing varying forms of “stay-at-home” orders, and restricting business functions outside of one’s home. In response, the Company has put restrictions on employee travel and working from its executive offices with many employees continuing their work remotely. While the Company is currently continuing the clinical trials it has underway in sites across the U.S., the Company expects that COVID-19 precautions may directly or indirectly impact the timeline for some of its clinical trials. For example, some of its clinical trial sites, including those located in areas severely impacted by the pandemic, have placed new patient enrollment into clinical trials on hold or, for patients travelling from out-of-state, have implemented a 14-day self-quarantine before appointments. Additionally, the Company’s expectations for the timing of first-in-human dosing of its ROR1 CAR-T therapy in China has been delayed. The Company considered the impacts of COVID-19 on the assumptions and estimates used to prepare its consolidated financial statements and determined that there were no material adverse impacts on the Company’s results of operations and financial position at December 31, 2021. The full extent to which the COVID-19 pandemic will directly or indirectly impact the Company’s business results of operations and financial condition, will depend on future development that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain or treat it, the success or failure of vaccination programs, the emergence of new variants of COVID-19, as well as the economic impact on local, regional, national and international markets. In response to the COVID-19 pandemic, the CARES Act was signed into law on March 27, 2020. The CARES Act, among other things, includes tax provisions relating to refundable payroll tax credits, deferment of employer’s social security payments, net operating loss utilization and carryback periods, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property (QIP), and authorized the PPP (see Note 5). The CARES Act had no material impact on the Company’s income tax provision for the years ended December 31, 2021 or 2020. 8. Income Taxes A reconciliation of the Company’s effective tax rate and federal statutory tax rate is as follows (in thousands): Federal income taxes State income taxes, net of federal benefit Permanent items Stock based compensation Research and development credit carryforwards Other, net Change in valuation allowance Provision for income taxes $ $ F-20 Years Ended December 31, 2021 2020 (6,579) $ (2,013) 4 512 (1,099) (131) 9,306 — $ (3,617) (1,113) (65) 226 (505) — 5,074 — Significant components of the Company’s net deferred tax assets are as follows (in thousands): Deferred tax assets: Net operating loss carryforwards Research and development credit carryforwards Accrued expenses Capitalized research and development costs Stock based compensation Other, net Total deferred tax assets Valuation allowance Deferred tax liabilities: Right of use asset Total deferred tax liabilities Net deferred tax assets December 31, 2021 2020 $ $ 21,254 $ 3,051 484 15,847 1,206 24 41,866 (41,845) 21 (21) (21) — $ 17,852 1,952 367 11,987 303 90 32,551 (32,540) 11 (11) (11) — As of December 31, 2021 and 2020, management assessed the realizability of deferred tax assets and evaluated the need for a valuation allowance for deferred tax assets on a jurisdictional basis. This evaluation utilizes the framework contained in ASC 740, Income Taxes, wherein management analyzes all positive and negative evidence available at the balance sheet date to determine whether all or some portion of the Company's deferred tax assets will not be realized. Under this guidance, a valuation allowance must be established for deferred tax assets when it is more-likely-than-not that the asset will not be realized. In assessing the realization of the Company's deferred tax assets, management considers all available evidence, both positive and negative. In concluding on the evaluation, management placed significant emphasis on guidance in ASC 740, which states that “a cumulative loss in recent years is a significant piece of negative evidence that is difficult to overcome.” Based upon available evidence, it was concluded on a more-likely-than-not basis that all deferred tax assets were not realizable as of December 31, 2021. Accordingly, a valuation allowance of $41.8 million has been recorded to offset this deferred tax asset. The valuation allowance increased by $9.3 million and $5.0 million for the years ended December 31, 2021 and 2020, respectively. At December 31, 2021, the Company had federal and state net operating loss (NOL) carryforwards of approximately $81.5 million and $59.4 million, respectively. Of the federal net operating losses at December 31, 2021, $55.2 million do not expire, and the remaining federal and state net operating loss carryforwards will begin expiring in 2033 and 2029, respectively, unless previously utilized. At December 31, 2021, the Company also had federal and state research and development credit carryforwards of approximately $2.1 million and $1.3 million, respectively. The federal research and development credit carryforwards will begin expiring in 2034 unless previously utilized. The state research and development credits do not expire. Pursuant to Internal Revenue Code Sections 382 and 383, annual use of the Company’s net operating loss and research and development tax credit carryforwards may be limited in the event a cumulative change in ownership of more than 50% occurs within a three-year period. The Company has not completed a Section 382 study to assess whether an ownership change has occurred or whether there have been multiple ownership changes since the Company’s formation due to the complexity and cost associated with such a study and the fact that there may be additional such ownership changes in the future. If eliminated, the related asset would be removed from the deferred tax asset schedule with a corresponding reduction in the valuation allowance. Due to the existence of the valuation allowance, limitations created by future ownership changes, if any, will not impact the Company’s effective tax rate. F-21 The Company recognizes a tax benefit from an uncertain tax position when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. Income tax positions must meet a more likely than not recognition at the effective date to be recognized. At December 31, 2021 and 2020, there were no unrecognized tax benefits recorded in the consolidated financial statements. The Company does not expect any material changes to unrecognized tax benefits within the next twelve months. The Company is subject to taxation in the United States federal and state jurisdictions. The Company’s 2014 through 2021 federal income tax and state income tax returns are subject to examination by federal and state tax authorities due to the carryforward of unutilized net operating losses and research and development credits. The Company is not currently under examination by any tax authority. The Company’s policy is to recognize interest and penalties related to income tax matters in income tax expense. The Company has not recognized interest or penalties in its consolidated statements of operations since inception. F-22 Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure. None. Item 9A. Controls and Procedures. Disclosure Controls and Procedures We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")) that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow for timely decisions regarding required disclosures. We have carried out an evaluation, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of December 31, 2021, the end of the period covered by this Annual Report. Based on the evaluation of these disclosure controls and procedures, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective as of December 31, 2021. Management's Report on Internal Control Over Financial Reporting We, as management of Oncternal Therapeutics, Inc., are responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Securities Exchange Act Rule 13a-15(f). Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with United States generally accepted accounting principles. Any system of internal control, no matter how well designed, has inherent limitations, including the possibility that a control can be circumvented or overridden and misstatements due to error or fraud may occur and not be detected. Also, because of changes in conditions, internal control effectiveness may vary over time. Accordingly, even an effective system of internal control will provide only reasonable assurance that the objectives of the internal control system are met. Under the supervision and with the participation of management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2021 using the criteria for effective internal control over financial reporting as described in "Internal Control — Integrated Framework," issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on this evaluation, we concluded that, as of December 31, 2021, our internal control over financial reporting was effective. Changes in Internal Control Over Financial Reporting There were no changes in our internal control over financial reporting during the fourth quarter of 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

(“we,” “us,” and “our”) has one class of securities registered pursuant to Section 12 of the Securities Exchange Act of 1934, as amended: common stock. General Description of Common Stock The following summary of the terms of our common stock does not purport to be complete and is subject to and qualified in its entirety by reference to our Restated Certificate of Incorporation, as amended (the “certificate of incorporation”), and Amended and Restated Bylaws (“bylaws”), which are filed as exhibits to our most recent Annual Report on Form 10-K and are incorporated by reference herein. We encourage you to read our certificate of incorporation and our bylaws for additional information. Under our certificate of incorporation, the total number of shares of all classes of stock that we have authority to issue is 125,000,000, consisting of 120,000,000 shares of common stock, par value $0.001 per share and 5,000,000 shares of preferred stock, par value $0.001 per share. On December 5, 2016, we effected a one-for-ten reverse stock split of our outstanding common stock. At the effective time of the reverse stock split, every ten shares of our issued and outstanding common stock was automatically combined and reclassified into one issued and outstanding share of common stock. No fractional shares of our common stock were issued and each holder of our common stock who would otherwise have been entitled to a fraction of a share of our common stock received a cash payment. In addition, as a result of the reverse stock split, proportionate adjustments were made to the per share exercise price and/or the number of shares issuable upon the exercise or vesting of all stock options, restricted stock units and warrants issued by us and outstanding immediately prior to the effective time of the reverse stock split, which resulted in a proportionate decrease in the number of shares of our common stock reserved for issuance upon exercise or vesting of such stock options, restricted stock units and warrants, and, in the case of stock options and warrants, a proportionate increase in the exercise price of all such stock options and warrants. The number of shares reserved for issuance under our equity compensation plans immediately prior to the effective time of the reverse stock split was reduced proportionately. On June 7, 2019, we effected a seven-for-one reverse stock split of our outstanding common stock. At the effective time of the reverse stock split, every seven shares of our issued and outstanding common stock was automatically combined and reclassified into one issued and outstanding share of common stock. No fractional shares of our common stock were issued and each holder of our common stock who would otherwise have been entitled to a fraction of a share of our common stock received a cash payment. In addition, as a result of the reverse stock split, proportionate adjustments were made to the per share exercise price and/or the number of shares issuable upon the exercise or vesting of all stock options, restricted stock units and warrants issued by us and outstanding immediately prior to the effective time of the reverse stock split, which resulted in a proportionate decrease in the number of shares of our common stock reserved for issuance upon exercise or vesting of such stock options, restricted stock units and warrants, and, in the case of stock options and warrants, a proportionate increase in the exercise price of all such stock options and warrants. The number of shares reserved for issuance under our equity compensation plans immediately prior to the effective time of the reverse stock split was reduced proportionately. The following summary description of our capital stock is based on the provisions of our certificate of incorporation and bylaws, the applicable provisions of the General Corporation Law of the State of Delaware (“DGCL”), and the agreements described below. This information may not be complete in all respects and is qualified entirely by reference to the provisions of our certificate of incorporation and bylaws, the DGCL and such agreements. For information on how to obtain copies of our certificate of incorporation, bylaws and such agreements, which are incorporated by reference as exhibits to the Annual Report on Form 10-K of which this Exhibit is a part. Common Stock Voting Rights The holders of our common stock are entitled to one vote for each share held of record on all matters properly submitted to a vote of stockholders; provided, however, that, except as otherwise required by law, holders of common stock shall not be entitled to vote on any amendment to the certification of incorporation that relates to solely to the terms of any outstanding series of preferred stock if the holders such preferred stock are entitled to vote thereon by law or pursuant to the certification of incorporation. The holders of our common stock do not have cumulative voting rights in the election of directors. Dividends Subject to preferences that may be applicable to any outstanding shares of preferred stock, the holders of common stock are entitled to receive ratably such dividends as may be declared by our board of directors out of legally available funds. Dissolution, Liquidation or Winding Up Upon our liquidation, dissolution or winding up, holders of our common stock are entitled to share ratably in all assets remaining after payment of liabilities and the liquidation preferences of any outstanding shares of preferred stock. Rights and Preferences Holders of common stock have no preemptive rights and no right to convert their common stock into any other securities. There are no redemption or sinking fund provisions applicable to our common stock. The rights of the holders of our common stock are subject to, and may be adversely affected by, the rights of holders of shares of any preferred stock that we may designate and issue in the future. Listing Our common stock is listed on the Nasdaq Capital Market under the symbol “ONCT.” Transfer Agent and Registrar The transfer agent and registrar for our common stock is Computershare Trust Company, N.A. Its address is 150 Royall Street, Canton, MA 02021. Anti-Takeover Effects of Provisions of Delaware Law and Our Charter Documents Delaware Takeover Statute. We are subject to Section 203 of the DGCL. Section 203 generally prohibits a public Delaware corporation such as us from engaging in a “business combination” with an “interested stockholder” for a period of three years following the time that the stockholder became an interested stockholder, unless: • • prior to the time the stockholder became an interested stockholder, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder; upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding (a) shares owned by persons who are directors and also officers and (b) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or • at or subsequent to the time the stockholder became an interested stockholder, the business combination is approved by the board and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66-2/3% of the outstanding voting stock which is not owned by the interested stockholder. Section 203 defines a business combination to include: • • • • • any merger or consolidation involving the corporation and the interested stockholder; any sale, lease, exchange, mortgage, pledge, transfer or other disposition (in one transaction or a series of transactions) involving the interested stockholder of 10% or more of the assets of the corporation (or its majority-owned subsidiary); subject to exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder; subject to exceptions, any transaction involving the corporation that has the effect, directly or indirectly, of increasing the proportionate share of the stock or any class or series of the corporation beneficially owned by the interested stockholder; and the receipt by the interested stockholder of the benefit, directly or indirectly (except proportionately as a stockholder of such corporation), of any loans, advances, guarantees, pledges or other financial benefits, other than certain benefits set forth in Section 203, provided by or through the corporation. In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person that is an affiliate or associate of such entity or person. Charter Documents. Our certificate of incorporation and bylaws provide that our board of directors be divided into three classes of directors, as nearly equal in number as possible, with each class serving a staggered three-year term. The classification system of electing directors may tend to discourage a third party from making a tender offer or otherwise attempting to obtain control of us since the classification of the board of directors generally increases the difficulty of replacing a majority of directors. In addition, our certificate of incorporation and bylaws: • • • • provide that any action required or permitted to be taken by our stockholders must be effected at a duly called annual or special meeting of stockholders and may not be effected by any consent in writing; establish advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted upon at a stockholder meeting; provide that the authorized number of directors may be changed only by resolution of the board of directors; and provide that special meetings of our stockholders may be called only by the chairman of our board of directors, our chief executive officer or our board of directors pursuant to a resolution adopted by a majority of the total number of authorized directors. The DGCL provides generally that the affirmative vote of a majority of the shares entitled to vote is required to amend a corporation’s bylaws, unless a corporation’s certificate of incorporation requires a greater percentage or also confers the power upon the corporation’s directors. Our bylaws may be amended or repealed by: • • the affirmative vote of a majority of our directors then in office; or the affirmative vote of the holders of at least 66-2/3% of the voting power of all then-outstanding shares of our capital stock entitled to vote generally in the election of directors The foregoing provisions of our certificate of incorporation may be amended or repealed only with the affirmative vote of a majority of our directors and the affirmative vote of the holders of at least 66-2/3% of the voting power of all then-outstanding shares of our capital stock entitled to vote generally in the election of directors. These and other provisions contained in our certificate of incorporation and bylaws could delay or discourage some types of transactions involving an actual or potential change in our control or change in our management, including transactions in which stockholders might otherwise receive a premium for their shares over then current prices, and may limit the ability of stockholders to remove current management or approve transactions that stockholders may deem to be in their best interests and, therefore, could adversely affect the price of our common stock. Exhibit 10.5 AMENDED AND RESTATED LICENSE AGREEMENT BETWEEN THE UNIVERSITY OF TENNESSEE RESEARCH FOUNDATION AND ONCTERNAL THERAPEUTICS, INC.

The Board may abolish any Committee or re-vest in itself any previously delegated authority at any time. ARTICLE IV. STOCK AVAILABLE FOR AWARDS 4.1 Number of Shares. Subject to adjustment under Article VIII and the terms of this Article IV, Awards may be made under the Plan covering up to the Overall Share Limit. As of the Effective Date, the Company will cease granting awards under the Prior Plan; however, Prior Plan Awards will remain subject to the terms of the applicable Prior Plan. Shares issued under the Plan may consist of authorized but unissued Shares, Shares purchased on the open market or treasury Shares. 4.2 Share Recycling. If all or any part of an Award or Prior Plan Award expires, lapses or is terminated, exchanged for cash, surrendered, repurchased, canceled without having been fully exercised or forfeited, in any case, in a manner that results in the Company acquiring Shares covered by the Award or Prior Plan Award at a price not greater than the price (as adjusted to reflect any Equity Restructuring) paid by the Participant for such Shares or not issuing any Shares covered by the Award or Prior Plan Award, the unused Shares covered by the Award or Prior Plan Award will, as applicable, become or again be available for Award grants under the Plan. Further, Shares delivered (either by actual delivery or attestation) to the Company by a Participant to satisfy the applicable exercise or purchase price of an Award or Prior Plan Award and/or to satisfy any applicable tax withholding obligation (including Shares retained by the Company from the Award or Prior Plan Award being exercised or purchased and/or creating the tax obligation) will, as applicable, become or again be available for Award grants under the Plan. The payment of Dividend Equivalents in cash in conjunction with any outstanding Awards or Prior Plan Awards shall not count against the Overall Share Limit. 4.3 Incentive Stock Option Limitations. Notwithstanding anything to the contrary herein, no more than 7,142,857 Shares may be issued pursuant to the exercise of Incentive Stock Options. 4.4 Substitute Awards. In connection with an entity’s merger or consolidation with the Company or the Company’s acquisition of an entity’s property or stock, the Administrator may grant Awards in substitution for any Options or other stock or stock-based awards granted before such merger or consolidation by such entity or its affiliate. Substitute Awards may be granted on such terms as the Administrator deems appropriate, notwithstanding limitations on Awards in the Plan. Substitute Awards will not count against the Overall Share Limit (nor shall Shares subject to a Substitute Award be added to the Shares available for Awards under the Plan as provided above), except that Shares acquired by exercise of substitute Incentive Stock Options will count against the maximum number of Shares that may be issued pursuant to the exercise of Incentive Stock Options under the Plan. Additionally, in the event that a company acquired by the Company or any Subsidiary or with which the Company or any Subsidiary combines has shares available under a pre-existing plan approved by stockholders and not adopted in contemplation of such acquisition or combination, the shares available for grant pursuant to the terms of such pre-existing plan (as adjusted, to the extent appropriate, using the exchange ratio or other adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration payable to the holders of common stock of the entities party to such acquisition or combination) may be used for Awards under the Plan and shall not reduce the Shares authorized for grant under the Plan (and Shares subject to such Awards shall not be added to the Shares available for Awards under the Plan as provided above); provided that Awards using such available shares shall not be made after the date awards or grants could have been made under the terms of the pre-existing plan, absent the acquisition or combination, and shall only be made to individuals who were not Employees or Directors prior to such acquisition or combination. 4.5 Non-Employee Director Compensation. Notwithstanding any provision to the contrary in the Plan, the Administrator may establish compensation for non-employee Directors from time to time, subject to the limitations in the Plan. The Administrator will from time to time determine the terms, conditions and amounts of all such non-employee Director compensation in its discretion and pursuant to the exercise of its business judgment, taking into account such factors, circumstances and considerations as it shall deem relevant from time to time, provided that the sum of any cash compensation, or other compensation, and the value (determined as of the grant date in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718, or any successor thereto) of Awards granted to a non-employee Director as compensation for services as a non-employee Director during any fiscal year of the Company may not exceed $750,000 increased to $1,000,000 in the fiscal year of a non-employee Director’s initial service as a non-employee Director. The Administrator may make exceptions to this limit for individual non-employee Directors in extraordinary circumstances, as the Administrator may determine in its discretion, provided that the non-employee Director receiving such additional compensation may not participate in the decision to award such compensation or in other contemporaneous compensation decisions involving non-employee Directors. 2 ARTICLE V. STOCK OPTIONS AND STOCK APPRECIATION RIGHTS 5.1 General. The Administrator may grant Options or Stock Appreciation Rights to Service Providers subject to the limitations in the Plan, including any limitations in the Plan that apply to Incentive Stock Options. The Administrator will determine the number of Shares covered by each Option and Stock Appreciation Right, the exercise price of each Option and Stock Appreciation Right and the conditions and limitations applicable to the exercise of each Option and Stock Appreciation Right. A Stock Appreciation Right will entitle the Participant (or other person entitled to exercise the Stock Appreciation Right) to receive from the Company upon exercise of the exercisable portion of the Stock Appreciation Right an amount determined by multiplying the excess, if any, of the Fair Market Value of one Share on the date of exercise over the exercise price per Share of the Stock Appreciation Right by the number of Shares with respect to which the Stock Appreciation Right is exercised, subject to any limitations of the Plan or that the Administrator may impose and payable in cash, Shares valued at Fair Market Value or a combination of the two as the Administrator may determine or provide in the Award Agreement. 5.2 Exercise Price. The Administrator will establish each Option’s and Stock Appreciation Right’s exercise price and specify the exercise price in the Award Agreement. The exercise price will not be less than 100% of the Fair Market Value on the grant date of the Option or Stock Appreciation Right. 5.3 Duration. Each Option or Stock Appreciation Right will be exercisable at such times and as specified in the Award Agreement, provided that the term of an Option or Stock Appreciation Right will not exceed ten (10) years. Notwithstanding the foregoing and unless determined otherwise by the Company, in the event that on the last business day of the term of an Option or Stock Appreciation Right (other than an Incentive Stock Option) (i) the exercise of the Option or Stock Appreciation Right is prohibited by Applicable Law, as determined by the Company, or (ii) Shares may not be purchased or sold by the applicable Participant due to any Company insider trading policy (including blackout periods) or a “lock-up” agreement undertaken in connection with an issuance of securities by the Company, the term of the Option or Stock Appreciation Right shall be extended until the date that is thirty (30) days after the end of the legal prohibition, black-out period or lock-up agreement, as determined by the Company; provided, however, in no event shall the extension last beyond the ten- (10)-year term of the applicable Option or Stock Appreciation Right. Notwithstanding the foregoing, if the Participant, prior to the end of the term of an Option or Stock Appreciation Right, violates the non-competition, non-solicitation, confidentiality or other similar restrictive covenant provisions of any employment contract, confidentiality and nondisclosure agreement or other agreement between the Participant and the Company or any of its Subsidiaries, the right of the Participant and the Participant’s transferees to exercise any Option or Stock Appreciation Right issued to the Participant shall terminate immediately upon such violation, unless the Company otherwise determines. In addition, if, prior to the end of the term of an Option or Stock Appreciation Right, the Participant is given notice by the Company or any of its Subsidiaries of the Participant’s Termination of Service by the Company or any of its Subsidiaries for Cause, and the effective date of such Termination of Service is subsequent to the date of the delivery of such notice, the right of the Participant and the Participant’s transferees to exercise any Option or Stock Appreciation Right issued to the Participant shall be suspended from the time of the delivery of such notice until the earlier of (i) such time as it is determined or otherwise agreed that the Participant’s service as a Service Provider will not be terminated for Cause as provided in such notice or (ii) the effective date of the Participant’s Termination of Service by the Company or any of its Subsidiaries for Cause (in which case the right of the Participant and the Participant’s transferees to exercise any Option or Stock Appreciation Right issued to the Participant will terminate immediately upon the effective date of such Termination of Service). 5.4 Exercise. Options and Stock Appreciation Rights may be exercised by delivering to the Company a written notice of exercise, in a form the Administrator approves (which may be electronic), 3 signed by the person authorized to exercise the Option or Stock Appreciation Right, together with, as applicable, payment in full (i) as specified in Section 5.5 for the number of Shares for which the Award is exercised and (ii) as specified in Section 9.5 for any applicable taxes. Unless the Administrator otherwise determines, an Option or Stock Appreciation Right may not be exercised for a fraction of a Share. 5.5 Payment Upon Exercise. Subject to any Company insider trading policy (including blackout periods) and Applicable Laws, the exercise price of an Option must be paid by: cash, wire transfer of immediately available funds or by check payable to the order of the Company, provided that the Company may limit the use of one of the foregoing payment forms if one or more of the payment forms below is permitted; (a) (b) if there is a public market for Shares at the time of exercise, unless the Company otherwise determines, (A) delivery (including electronically or telephonically to the extent permitted by the Company) of an irrevocable and unconditional undertaking by a broker acceptable to the Company to deliver promptly to the Company sufficient funds to pay the exercise price, or (B) the Participant’s delivery to the Company of a copy of irrevocable and unconditional instructions to a broker acceptable to the Company to deliver promptly to the Company cash or a check sufficient to pay the exercise price; provided that such amount is paid to the Company at such time as may be required by the Administrator; owned by the Participant valued at their Fair Market Value; (c) to the extent permitted by the Administrator, delivery (either by actual delivery or attestation) of Shares valued at their Fair Market Value on the exercise date; (d) to the extent permitted by the Administrator, surrendering Shares then issuable upon the Option’s exercise Administrator determines is good and valuable consideration; or (e) to the extent permitted by the Administrator, delivery of a promissory note or any other property that the Administrator. (f) to the extent permitted by the Company, any combination of the above payment forms approved by the ARTICLE VI. RESTRICTED STOCK; RESTRICTED STOCK UNITS 6.1 General. The Administrator may grant Restricted Stock, or the right to purchase Restricted Stock, to any Service Provider, subject to the Company’s right to repurchase all or part of such Shares at their issue price or other stated or formula price from the Participant (or to require forfeiture of such Shares) if conditions the Administrator specifies in the Award Agreement are not satisfied before the end of the applicable restriction period or periods that the Administrator establishes for such Award. In addition, the Administrator may grant to Service Providers Restricted Stock Units, which may be subject to vesting and forfeiture conditions during the applicable restriction period or periods, as set forth in an Award Agreement. The Administrator will determine and set forth in the Award Agreement the terms and conditions for each Restricted Stock and Restricted Stock Unit Award, subject to the conditions and limitations contained in the Plan. 6.2 Restricted Stock. Dividends. Participants holding Shares of Restricted Stock will be entitled to all ordinary cash dividends paid with respect to such Shares, unless the Administrator provides otherwise in the Award Agreement. In addition, unless the Administrator provides otherwise, if any dividends or (a) 4 distributions are paid in Shares, or consist of a dividend or distribution to holders of Common Stock of property other than an ordinary cash dividend, the Shares or other property will be subject to the same restrictions on transferability and forfeitability as the Shares of Restricted Stock with respect to which they were paid. its designee) any stock certificates issued in respect of Shares of Restricted Stock, together with a stock power endorsed in blank. (b) Stock Certificates. The Company may require that the Participant deposit in escrow with the Company (or 6.3 Restricted Stock Units. Settlement. The Administrator may provide that settlement of Restricted Stock Units will occur upon or as soon as reasonably practicable after the Restricted Stock Units vest or will instead be deferred, on a mandatory basis or at the Participant’s election, in a manner intended to comply with Section 409A. (a) Restricted Stock Unit unless and until the Shares are delivered in settlement of the Restricted Stock Unit. (b) Stockholder Rights. A Participant will have no rights of a stockholder with respect to Shares subject to any (c) Dividend Equivalents. If the Administrator provides, a grant of Restricted Stock Units may provide a Participant with the right to receive Dividend Equivalents. Dividend Equivalents may be paid currently or credited to an account for the Participant, settled in cash or Shares and subject to the same restrictions on transferability and forfeitability as the Restricted Stock Units with respect to which the Dividend Equivalents are granted and subject to other terms and conditions as set forth in the Award Agreement. ARTICLE VII. OTHER STOCK OR CASH BASED AWARDS Other Stock or Cash Based Awards may be granted to Participants, including Awards entitling Participants to receive Shares to be delivered in the future and including annual or other periodic or long-term cash bonus awards (whether based on specified Performance Criteria or otherwise), in each case subject to any conditions and limitations in the Plan. Such Other Stock or Cash Based Awards will also be available as a payment form in the settlement of other Awards, as standalone payments and as payment in lieu of compensation to which a Participant is otherwise entitled. Other Stock or Cash Based Awards may be paid in Shares, cash or other property, as the Administrator determines. Subject to the provisions of the Plan, the Administrator will determine the terms and conditions of each Other Stock or Cash Based Award, including any purchase price, performance goal (which may be based on the Performance Criteria), transfer restrictions, and vesting conditions, which will be set forth in the applicable Award Agreement. ARTICLE VIII. ADJUSTMENTS FOR CHANGES IN COMMON STOCK AND CERTAIN OTHER EVENTS 8.1 Equity Restructuring(a) . In connection with any Equity Restructuring, notwithstanding anything to the contrary in this Article VIII, the Administrator will equitably adjust each outstanding Award as it deems appropriate to reflect the Equity Restructuring, which may include adjusting the number and type of securities subject to each outstanding Award and/or the Award’s exercise price or grant price (if applicable), granting new Awards to Participants, and making a cash payment to Participants. The adjustments provided under this Section 8.1 will be nondiscretionary and final and binding on the affected 5 Participant and the Company; provided that the Administrator will determine whether an adjustment is equitable. 8.2 Corporate Transactions. In the event of any dividend or other distribution (whether in the form of cash, Common Stock, other securities, or other property), reorganization, merger, consolidation, combination, amalgamation, repurchase, recapitalization, liquidation, dissolution, or sale, transfer, exchange or other disposition of all or substantially all of the assets of the Company, or sale or exchange of Common Stock or other securities of the Company, Change in Control, issuance of warrants or other rights to purchase Common Stock or other securities of the Company, other similar corporate transaction or event, other unusual or nonrecurring transaction or event affecting the Company or its financial statements or any change in any Applicable Laws or accounting principles, the Administrator, on such terms and conditions as it deems appropriate, either by the terms of the Award or by action taken prior to the occurrence of such transaction or event (except that action to give effect to a change in Applicable Law or accounting principles may be made within a reasonable period of time after such change) and either automatically or upon the Participant’s request, is hereby authorized to take any one or more of the following actions whenever the Administrator determines that such action is appropriate in order to (x) prevent dilution or enlargement of the benefits or potential benefits intended by the Company to be made available under the Plan or with respect to any Award granted or issued under the Plan, (y) to facilitate such transaction or event or (z) give effect to such changes in Applicable Laws or accounting principles: (a) To provide for the cancellation of any such Award in exchange for either an amount of cash or other property with a value equal to the amount that could have been obtained upon the exercise or settlement of the vested portion of such Award or realization of the Participant’s rights under the vested portion of such Award, as applicable; provided that, if the amount that could have been obtained upon the exercise or settlement of the vested portion of such Award or realization of the Participant’s rights, in any case, is equal to or less than zero, then the Award may be terminated without payment; thereby, notwithstanding anything to the contrary in the Plan or the provisions of such Award; (b) To provide that such Award shall vest and, to the extent applicable, be exercisable as to all Shares covered (c) To provide that such Award be assumed by the successor or survivor corporation, or a parent or subsidiary thereof, or shall be substituted for by awards covering the stock of the successor or survivor corporation, or a parent or subsidiary thereof, with appropriate adjustments as to the number and kind of Shares and/or applicable exercise or purchase price, in all cases, as determined by the Administrator; (d) To make adjustments in the number and type of Shares (or other securities or property) subject to outstanding Awards and/or with respect to which Awards may be granted under the Plan (including, but not limited to, adjustments of the limitations in Article IV hereof on the maximum number and kind of Shares which may be issued) and/or in the terms and conditions of (including the grant or exercise price), and the criteria included in, outstanding Awards; (e) (f) applicable event. To replace such Award with other rights or property selected by the Administrator; and/or To provide that the Award will terminate and cannot vest, be exercised or become payable after the 8.3 Effect of Non-Assumption in a Change in Control. Notwithstanding the provisions of Section 8.2 above, if a Change in Control occurs and a Participant’s Awards are not continued, converted, 6 assumed, or replaced with a substantially similar award by (a) the Company, or (b) a Successor Entity (as defined below) or its parent or subsidiary (an “Assumption”), and provided that the Participant has not had a Termination of Service, then, immediately prior to the Change in Control, such Awards shall become fully vested, exercisable and/or payable, as applicable, and all forfeiture, repurchase and other restrictions on such Awards shall lapse, in which case, such Awards shall be canceled upon the consummation of the Change in Control in exchange for the right to receive the Change in Control consideration payable to other holders of Common Stock (i) which may be on such terms and conditions as apply generally to holders of Common Stock under the Change in Control documents (including, without limitation, any escrow, earn-out or other deferred consideration provisions) or such other terms and conditions as the Administrator may provide, and (ii) determined by reference to the number of Shares subject to such Awards and net of any applicable exercise price; provided that to the extent that any Awards constitute “nonqualified deferred compensation” that may not be paid upon the Change in Control under Section 409A without the imposition of taxes thereon under Section 409A, the timing of such payments shall be governed by the applicable Award Agreement (subject to any deferred consideration provisions applicable under the Change in Control documents); and provided, further, that if the amount to which a Participant would be entitled upon the settlement or exercise of such Award at the time of the Change in Control is equal to or less than zero, then such Award may be terminated without payment. The Administrator shall determine whether an Assumption of an Award has occurred in connection with a Change in Control. 8.4 Administrative Stand Still. In the event of any pending stock dividend, stock split, combination or exchange of Shares, merger, consolidation or other distribution (other than normal cash dividends) of Company assets to stockholders, or any other extraordinary transaction or change affecting the Shares or the share price of Common Stock, including any Equity Restructuring or any securities offering or other similar transaction, for administrative convenience, the Administrator may refuse to permit the exercise of any Award for up to sixty (60) days before or after such transaction. 8.5 General. Except as expressly provided in the Plan or the Administrator’s action under the Plan, no Participant will have any rights due to any subdivision or consolidation of Shares of any class, dividend payment, increase or decrease in the number of Shares of any class or dissolution, liquidation, merger, or consolidation of the Company or other corporation. Except as expressly provided with respect to an Equity Restructuring under Section 8.1 above or the Administrator’s action under the Plan, no issuance by the Company of Shares of any class, or securities convertible into Shares of any class, will affect, and no adjustment will be made regarding, the number of Shares subject to an Award or the Award’s grant or exercise price. The existence of the Plan, any Award Agreements and the Awards granted hereunder will not affect or restrict in any way the Company’s right or power to make or authorize (i) any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or its business, (ii) any merger, consolidation dissolution or liquidation of the Company or sale of Company assets or (iii) any sale or issuance of securities, including securities with rights superior to those of the Shares or securities convertible into or exchangeable for Shares. The Administrator may treat Participants and Awards (or portions thereof) differently under this Article VIII. ARTICLE IX. GENERAL PROVISIONS APPLICABLE TO AWARDS 9.1 Transferability. Except as the Administrator may determine or provide in an Award Agreement or otherwise for Awards other than Incentive Stock Options, Awards may not be sold, assigned, transferred, pledged or otherwise encumbered, either voluntarily or by operation of law, except by will or the laws of descent and distribution, or, subject to the Administrator’s consent, pursuant to a domestic relations order, and, during the life of the Participant, will be exercisable only by the Participant. References to a Participant, to the extent relevant in the context, will include references to a Participant’s authorized transferee that the Administrator specifically approves. 7 9.2 Documentation. Each Award will be evidenced in an Award Agreement, which may be written or electronic, as the Administrator determines. Each Award may contain terms and conditions in addition to those set forth in the Plan. 9.3 Discretion. Except as the Plan otherwise provides, each Award may be made alone or in addition or in relation to any other Award. The terms of each Award to a Participant need not be identical, and the Administrator need not treat Participants or Awards (or portions thereof) uniformly. 9.4 Termination of Status. The Administrator will determine how the disability, death, retirement, authorized leave of absence or any other change or purported change in a Participant’s Service Provider status affects an Award and the extent to which, and the period during which, the Participant, the Participant’s legal representative, conservator, guardian or Designated Beneficiary may exercise rights under the Award, if applicable. 9.5 Withholding. Each Participant must pay the Company, or make provision satisfactory to the Administrator for payment of, any taxes required by law to be withheld in connection with such Participant’s Awards by the date of the event creating the tax liability. The Company may deduct an amount sufficient to satisfy such tax obligations based on the applicable statutory withholding rates (or such other rate as may be determined by the Company after considering any accounting consequences or costs) from any payment of any kind otherwise due to a Participant. In the absence of a contrary determination by the Company (or, with respect to withholding pursuant to clause (ii) below with respect to Awards held by individuals subject to Section 16 of the Exchange Act, a contrary determination by the Administrator), all tax withholding obligations will be calculated based on the minimum applicable statutory withholding rates. Subject to any Company insider trading policy (including blackout periods), Participants may satisfy such tax obligations (i) in cash, by wire transfer of immediately available funds, by check made payable to the order of the Company, provided that the Company may limit the use of the foregoing payment forms if one or more of the payment forms below is permitted, (ii) to the extent permitted by the Administrator, in whole or in part by delivery of Shares, including Shares delivered by attestation and Shares retained from the Award creating the tax obligation, valued at their Fair Market Value on the date of delivery, (iii) if there is a public market for Shares at the time the tax obligations are satisfied, unless the Company otherwise determines, (A) delivery (including electronically or telephonically to the extent permitted by the Company) of an irrevocable and unconditional undertaking by a broker acceptable to the Company to deliver promptly to the Company sufficient funds to satisfy the tax obligations, or (B) delivery by the Participant to the Company of a copy of irrevocable and unconditional instructions to a broker acceptable to the Company to deliver promptly to the Company cash or a check sufficient to satisfy the tax withholding; provided that such amount is paid to the Company at such time as may be required by the Administrator, or (iv) to the extent permitted by the Company, any combination of the foregoing payment forms approved by the Administrator. Notwithstanding any other provision of the Plan, the number of Shares which may be so delivered or retained pursuant to clause (ii) of the immediately preceding sentence shall be limited to the number of Shares which have a Fair Market Value on the date of delivery or retention no greater than the aggregate amount of such liabilities based on the maximum individual statutory tax rate in the applicable jurisdiction at the time of such withholding (or such other rate as may be required to avoid the liability classification of the applicable award under generally accepted accounting principles in the United States of America); provided, however, to the extent such Shares were acquired by Participant from the Company as compensation, the Shares must have been held for the minimum period required by applicable accounting rules to avoid a charge to the Company’s earnings for financial reporting purposes; provided, further, that, any such Shares delivered or retained shall be rounded up to the nearest whole Share to the extent rounding up to the nearest whole Share does not result in the liability classification of the applicable Award under generally accepted accounting principles in the United States of America. If any tax withholding obligation will be satisfied under clause (ii) above by the Company’s retention of Shares from the Award creating the tax obligation and there is a public market for Shares at the time the tax obligation is satisfied, the Company 8 may elect to instruct any brokerage firm determined acceptable to the Company for such purpose to sell on the applicable Participant’s behalf some or all of the Shares retained and to remit the proceeds of the sale to the Company or its designee, and each Participant’s acceptance of an Award under the Plan will constitute the Participant’s authorization to the Company and instruction and authorization to such brokerage firm to complete the transactions described in this sentence. 9.6 Amendment of Award; Repricing. The Administrator may amend, modify or terminate any outstanding Award, including by substituting another Award of the same or a different type, changing the exercise or settlement date, and converting an Incentive Stock Option to a Non-Qualified Stock Option. The Participant’s consent to such action will be required unless (i) the action, taking into account any related action, does not materially and adversely affect the Participant’s rights under the Award, or (ii) the change is permitted under Article VIII or pursuant to Section 10.6. Notwithstanding the foregoing or anything in the Plan to the contrary, the Administrator may, without the approval of the stockholders of the Company, reduce the exercise price per share of outstanding Options or Stock Appreciation Rights or cancel outstanding Options or Stock Appreciation Rights in exchange for cash, other Awards or Options or Stock Appreciation Rights with an exercise price per share that is less than the exercise price per share of the original Options or Stock Appreciation Rights. 9.7 Conditions on Delivery of Stock. The Company will not be obligated to deliver any Shares under the Plan or remove restrictions from Shares previously delivered under the Plan until (i) all Award conditions have been met or removed to the Company’s satisfaction, (ii) as determined by the Company, all other legal matters regarding the issuance and delivery of such Shares have been satisfied, including any applicable securities laws and stock exchange or stock market rules and regulations, and (iii) the Participant has executed and delivered to the Company such representations or agreements as the Administrator deems necessary or appropriate to satisfy any Applicable Laws. The Company’s inability to obtain authority from any regulatory body having jurisdiction, which the Administrator determines is necessary to the lawful issuance and sale of any securities, will relieve the Company of any liability for failing to issue or sell such Shares as to which such requisite authority has not been obtained. 9.8 Acceleration. The Administrator may at any time provide that any Award will become immediately vested and fully or partially exercisable, free of some or all restrictions or conditions, or otherwise fully or partially realizable. 9.9 Additional Terms of Incentive Stock Options. The Administrator may grant Incentive Stock Options only to employees of the Company, any of its present or future parent or subsidiary corporations, as defined in Sections 424(e) or (f) of the Code, respectively, and any other entities the employees of which are eligible to receive Incentive Stock Options under the Code. If an Incentive Stock Option is granted to a Greater Than 10% Stockholder, the exercise price will not be less than 110% of the Fair Market Value on the Option’s grant date, and the term of the Option will not exceed five (5) years. All Incentive Stock Options will be subject to and construed consistently with Section 422 of the Code. By accepting an Incentive Stock Option, the Participant agrees to give prompt notice to the Company of dispositions or other transfers (other than in connection with a Change in Control) of Shares acquired under the Option made within (i) two years from the grant date of the Option or (ii) one year after the transfer of such Shares to the Participant, specifying the date of the disposition or other transfer and the amount the Participant realized, in cash, other property, assumption of indebtedness or other consideration, in such disposition or other transfer. Neither the Company nor the Administrator will be liable to a Participant, or any other party, if an Incentive Stock Option fails or ceases to qualify as an “incentive stock option” under Section 422 of the Code. Any Incentive Stock Option or portion thereof that fails to qualify as an “incentive stock option” under Section 422 of the Code for any reason, including becoming exercisable with respect to Shares having a Fair Market Value exceeding the $100,000 limitation under Treasury Regulation Section 1.422-4, will be a Non-Qualified Stock Option. 9 ARTICLE X. MISCELLANEOUS 10.1 No Right to Employment or Other Status. No person will have any claim or right to be granted an Award, and the grant of an Award will not be construed as giving a Participant the right to continued employment or any other relationship with the Company. The Company expressly reserves the right at any time to dismiss or otherwise terminate its relationship with a Participant free from any liability or claim under the Plan or any Award, except as expressly provided in an Award Agreement. 10.2 No Rights as Stockholder; Certificates. Subject to the Award Agreement, no Participant or Designated Beneficiary will have any rights as a stockholder with respect to any Shares to be distributed under an Award until becoming the record holder of such Shares. Notwithstanding any other provision of the Plan, unless the Administrator otherwise determines or Applicable Laws require, the Company will not be required to deliver to any Participant certificates evidencing Shares issued in connection with any Award and instead such Shares may be recorded in the books of the Company (or, as applicable, its transfer agent or stock plan administrator). The Company may place legends on stock certificates issued under the Plan that the Administrator deems necessary or appropriate to comply with Applicable Laws. 10.3 Effective Date and Term of Plan. The Plan was approved by the Board on April 16, 2019. The Plan shall be effective (the “Effective Date”) on the day prior to the date of the closing of the transactions contemplated by that certain Agreement and Plan of Merger and Reorganization, dated as of March 6, 2019 by and among the Company, Grizzly Merger Sub, Inc. and Oncternal Therapeutics, Inc. (as amended, the “Merger Agreement”), provided that it is approved by a majority of the Company’s stockholders at a duly held meeting prior to such date and occurring within twelve (12) months following the date the Board approved Plan, and provided further that the effectiveness of the Plan is subject to the consummation of the transactions contemplated by the Merger Agreement. If the Plan is not approved by the Company’s stockholders within the foregoing time frame, or if the Merger Agreement is terminated prior to the consummation of the transactions contemplated thereby, the Plan will not become effective. The Plan shall remain in effect until the tenth (10th) anniversary of the date the Board adopted the Plan, but Awards previously granted may extend beyond that date in accordance with the Plan. The Plan will be submitted for approval of the Company's stockholders within twelve (12) months following the date the Board approved the Plan. 10.4 Amendment of Plan. The Administrator may amend, suspend or terminate the Plan at any time; provided that no amendment, other than an increase to the Overall Share Limit, may materially and adversely affect any Award outstanding at the time of such amendment without the affected Participant’s consent. No Awards may be granted under the Plan during any suspension period or after the Plan’s termination. Awards outstanding at the time of any Plan suspension or termination will continue to be governed by the Plan and the Award Agreement, as in effect before such suspension or termination. The Board will obtain stockholder approval of any Plan amendment to the extent necessary to comply with Applicable Laws. 10.5 Provisions for Foreign Participants. The Administrator may modify Awards granted to Participants who are foreign nationals or employed outside the United States or establish subplans or procedures under the Plan to address differences in laws, rules, regulations or customs of such foreign jurisdictions with respect to tax, securities, currency, employee benefit or other matters. 10.6 10 Section 409A. (a) General. The Company intends that all Awards be structured to comply with, or be exempt from, Section 409A, such that no adverse tax consequences, interest, or penalties under Section 409A apply. Notwithstanding anything in the Plan or any Award Agreement to the contrary, the Administrator may, without a Participant’s consent, amend this Plan or Awards, adopt policies and procedures, or take any other actions (including amendments, policies, procedures and retroactive actions) as are necessary or appropriate to preserve the intended tax treatment of Awards, including any such actions intended to (A) exempt this Plan or any Award from Section 409A, or (B) comply with Section 409A, including regulations, guidance, compliance programs and other interpretative authority that may be issued after an Award’s grant date. The Company makes no representations or warranties as to an Award’s tax treatment under Section 409A or otherwise. The Company will have no obligation under this Section 10.6 or otherwise to avoid the taxes, penalties or interest under Section 409A with respect to any Award and will have no liability to any Participant or any other person if any Award, compensation or other benefits under the Plan are determined to constitute noncompliant “nonqualified deferred compensation” subject to taxes, penalties or interest under Section 409A. (b) Separation from Service. If an Award constitutes “nonqualified deferred compensation” under Section 409A, any payment or settlement of such Award upon a termination of a Participant’s Service Provider relationship will, to the extent necessary to avoid taxes under Section 409A, be made only upon the Participant’s “separation from service” (within the meaning of Section 409A), whether such “separation from service” occurs upon or after the termination of the Participant’s Service Provider relationship. For purposes of this Plan or any Award Agreement relating to any such payments or benefits, references to a “termination,” “termination of employment” or like terms means a “separation from service.” (c) Payments to Specified Employees. Notwithstanding any contrary provision in the Plan or any Award Agreement, any payment(s) of “nonqualified deferred compensation” required to be made under an Award to a “specified employee” (as defined under Section 409A and as the Administrator determines) due to his or her “separation from service” will, to the extent necessary to avoid taxes under Section 409A(a)(2)(B)(i) of the Code, be delayed for the six- (6)-month period immediately following such “separation from service” (or, if earlier, until the specified Employee’s death) and will instead be paid (as set forth in the Award Agreement) on the day immediately following such six- (6)month period or as soon as administratively practicable thereafter (without interest). Any payments of “nonqualified deferred compensation” under such Award payable more than six (6) months following the Participant’s “separation from service” will be paid at the time or times the payments are otherwise scheduled to be made. 10.7 Limitations on Liability. Notwithstanding any other provisions of the Plan, no individual acting as a director, officer, other Employee or agent of the Company or any Subsidiary will be liable to any Participant, former Participant, spouse, beneficiary, or any other person for any claim, loss, liability, or expense incurred in connection with the Plan or any Award, and such individual will not be personally liable with respect to the Plan because of any contract or other instrument executed in his or her capacity as an Administrator, director, officer, other Employee or agent of the Company or any Subsidiary. The Company will indemnify and hold harmless each director, officer, other Employee and agent of the Company or any Subsidiary that has been or will be granted or delegated any duty or power relating to the Plan’s administration or interpretation, against any cost or expense (including attorneys’ fees) or liability (including any sum paid in settlement of a claim with the Administrator’s approval) arising from any act or omission concerning this Plan unless arising from such person’s own fraud or bad faith. 10.8 10.9 Data Privacy 11 . As a condition for receiving any Award, each Participant explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of personal data as described in this section by and among the Company and its Subsidiaries and affiliates exclusively for implementing, administering and managing the Participant’s participation in the Plan. The Company and its Subsidiaries and affiliates may hold certain personal information about a Participant, including the Participant’s name, address and telephone number; birthdate; social security, insurance number or other identification number; salary; nationality; job title(s); any Shares held in the Company or its Subsidiaries and affiliates; and Award details, to implement, manage and administer the Plan and Awards (the “Data”). The Company and its Subsidiaries and affiliates may transfer the Data amongst themselves as necessary to implement, administer and manage a Participant’s participation in the Plan, and the Company and its Subsidiaries and affiliates may transfer the Data to third parties assisting the Company with Plan implementation, administration and management. These recipients may be located in the Participant’s country, or elsewhere, and the Participant’s country may have different data privacy laws and protections than the recipients’ country. By accepting an Award, each Participant authorizes such recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, to implement, administer and manage the Participant’s participation in the Plan, including any required Data transfer to a broker or other third party with whom the Company or the Participant may elect to deposit any Shares. The Data related to a Participant will be held only as long as necessary to implement, administer, and manage the Participant’s participation in the Plan. A Participant may, at any time, view the Data that the Company holds regarding such Participant, request additional information about the storage and processing of the Data regarding such Participant, recommend any necessary corrections to the Data regarding the Participant or refuse or withdraw the consents in this Section 10.8 in writing, without cost, by contacting the local human resources representative. The Company may cancel Participant’s ability to participate in the Plan and, in the Administrator’s discretion, the Participant may forfeit any outstanding Awards if the Participant refuses or withdraws the consents in this Section 10.8. For more information on the consequences of refusing or withdrawing consent, Participants may contact their local human resources representative. 10.10 Severability. If any portion of the Plan or any action taken under it is held illegal or invalid for any reason, the illegality or invalidity will not affect the remaining parts of the Plan, and the Plan will be construed and enforced as if the illegal or invalid provisions had been excluded, and the illegal or invalid action will be null and void. 10.11 Governing Documents. If any contradiction occurs between the Plan and any Award Agreement or other written agreement between a Participant and the Company (or any Subsidiary) that the Administrator has approved, the Plan will govern, unless it is expressly specified in such Award Agreement or other written document that a specific provision of the Plan will not apply. 10.12 Governing Law. The Plan and all Awards will be governed by and interpreted in accordance with the laws of the State of Delaware, disregarding any state’s choice-of-law principles requiring the application of a jurisdiction’s laws other than the State of Delaware. 10.13 Claw-back Provisions. All Awards (including, without limitation, any proceeds, gains or other economic benefit actually or constructively received by Participant upon any receipt or exercise of any Award or upon the receipt or resale of any Shares underlying the Award) shall be subject to the provisions of any claw-back policy implemented by the Company, including, without limitation, any claw-back policy adopted to comply with Applicable Laws (including the Dodd-Frank Wall Street Reform and Consumer Protection Act and any rules or regulations promulgated thereunder) as and to the extent set forth in such claw-back policy or the Award Agreement. 10.14 Titles and Headings. The titles and headings in the Plan are for convenience of reference only and, if any conflict, the Plan’s text, rather than such titles or headings, will control. 12 10.15 Conformity to Securities Laws. Participant acknowledges that the Plan is intended to conform to the extent necessary with Applicable Laws. Notwithstanding anything herein to the contrary, the Plan and all Awards will be administered only in conformance with Applicable Laws. To the extent Applicable Laws permit, the Plan and all Award Agreements will be deemed amended as necessary to conform to Applicable Laws. 10.16 Relationship to Other Benefits. No payment under the Plan will be taken into account in determining any benefits under any pension, retirement, savings, profit sharing, group insurance, welfare or other benefit plan of the Company or any Subsidiary except as expressly provided in writing in such other plan or an agreement thereunder. 10.17 Broker-Assisted Sales. In the event of a broker-assisted sale of Shares in connection with the payment of amounts owed by a Participant under or with respect to the Plan or Awards, including amounts to be paid under the final sentence of Section 9.5: (a) any Shares to be sold through the broker-assisted sale will be sold on the day the payment first becomes due, or as soon thereafter as practicable; (b) such Shares may be sold as part of a block trade with other Participants in the Plan in which all participants receive an average price; (c) the applicable Participant will be responsible for all broker’s fees and other costs of sale, and by accepting an Award, each Participant agrees to indemnify and hold the Company harmless from any losses, costs, damages, or expenses relating to any such sale; (d) to the extent the Company or its designee receives proceeds of such sale that exceed the amount owed, the Company will pay such excess in cash to the applicable Participant as soon as reasonably practicable; (e) the Company and its designees are under no obligation to arrange for such sale at any particular price; and (f) in the event the proceeds of such sale are insufficient to satisfy the Participant’s applicable obligation, the Participant may be required to pay immediately upon demand to the Company or its designee an amount in cash sufficient to satisfy any remaining portion of the Participant’s obligation.

The Plan, the Grant Notice and this Agreement constitute the entire agreement of the parties and supersede in their entirety all prior undertakings and agreements of the Company and Participant with respect to the subject matter hereof. 4.8 Agreement Severable. In the event that any provision of the Grant Notice or this Agreement is held illegal or invalid, the provision will be severable from, and the illegality or invalidity of the provision will not be construed to have any effect on, the remaining provisions of the Grant Notice or this Agreement. 4.9 Limitation on Participant’s Rights. Participation in the Plan confers no rights or interests other than as herein provided. This Agreement creates only a contractual obligation on the part of the Company as to amounts payable and may not be construed as creating a trust. Neither the Plan nor any underlying program, in and of itself, has any assets. Participant will have only the rights of a general unsecured creditor of the Company with respect to amounts credited and benefits payable, if any, with respect to the Option, and rights no greater than the right to receive the Shares as a general unsecured creditor with respect to the Option, as and when exercised pursuant to the terms hereof. 4.10 Not a Contract of Employment. Nothing in the Plan, the Grant Notice or this Agreement confers upon Participant any right to continue in the employ or service of the Company or any Subsidiary or interferes with or restricts in any way the rights of the Company and its Subsidiaries, which rights are hereby expressly reserved, to discharge or terminate the services of Participant at any time for any reason whatsoever, with or without Cause, except to the extent expressly provided otherwise in a written agreement between the Company or a Subsidiary and Participant. 4.11 Counterparts. The Grant Notice may be executed in one or more counterparts, including by way of any electronic signature, subject to Applicable Law, each of which will be deemed an original and all of which together will constitute one instrument. 4.12 Incentive Stock Options. If the Option is designated as an Incentive Stock Option: Participant acknowledges that to the extent the aggregate fair market value of shares (determined as of the time the option with respect to the shares is granted) with respect to which stock options intended to qualify as “incentive stock options” under Section 422 of the Code, including the (a) US-DOCS\109067876.1 A-3 Option, are exercisable for the first time by Participant during any calendar year exceeds $100,000 or if for any other reason such stock options do not qualify or cease to qualify for treatment as “incentive stock options” under Section 422 of the Code, such stock options (including the Option) will be treated as non-qualified stock options. Participant further acknowledges that the rule set forth in the preceding sentence will be applied by taking the Option and other stock options into account in the order in which they were granted, as determined under Section 422(d) of the Code. Participant acknowledges that amendments or modifications made to the Option pursuant to the Plan that would cause the Option to become a Non-Qualified Stock Option will not materially or adversely affect Participant’s rights under the Option, and that any such amendment or modification shall not require Participant’s consent. Participant also acknowledges that if the Option is exercised more than three (3) months after Participant’s Termination of Service as an Employee, other than by reason of death or disability, the Option will be taxed as a Non-Qualified Stock Option. (b) Participant will give prompt written notice to the Company of any disposition or other transfer of any Shares acquired under this Agreement if such disposition or other transfer is made (a) within two (2) years from the Grant Date or (b) within one (1) year after the transfer of such Shares to Participant. Such notice will specify the date of such disposition or other transfer and the amount realized, in cash, other property, assumption of indebtedness or other consideration, by Participant in such disposition or other transfer.

PARTICIPANT By: Print Name: Title: By: Print Name: EXHIBIT A RESTRICTED STOCK UNIT AGREEMENT Capitalized terms not specifically defined in this Agreement have the meanings specified in the Grant Notice or, if not defined in the Grant Notice, in the Plan. ARTICLE I. GENERAL 1.1 Award of RSUs. The Company has granted the RSUs to Participant effective as of the grant date set forth in the Grant Notice (the “Grant Date”). Each RSU represents the right to receive one Share, as set forth in this Agreement. Participant will have no right to the distribution of any Shares until the time (if ever) the RSUs have vested. 1.2 Incorporation of Terms of Plan. The RSUs are subject to the terms and conditions set forth in this Agreement and the Plan, which is incorporated herein by reference. In the event of any inconsistency between the Plan and this Agreement, the terms of the Plan will control. 1.3 Unsecured Promise. The RSUs will at all times prior to settlement represent an unsecured Company obligation payable only from the Company’s general assets. ARTICLE II. VESTING; FORFEITURE AND SETTLEMENT 2.1 Vesting; Forfeiture. The RSUs will vest according to the vesting schedule in the Grant Notice (the “Vesting Schedule”), except that any fraction of an RSU that would otherwise be vested will be accumulated and will vest only when a whole RSU has accumulated. Except as provided in the Grant Notice, in the event of Participant’s Termination of Service for any reason, all unvested RSUs will immediately and automatically be cancelled and forfeited, except as otherwise determined by the Administrator or provided in a binding written agreement between Participant and the Company. Unless and until the RSUs have vested in accordance with the Vesting Schedule set forth in the Grant Notice, Participant will have no right to any distribution with respect to such RSUs. 2.2 Settlement. (a) RSUs will be paid in Shares as soon as administratively practicable after the vesting of the applicable RSU, but in no event more than ten (10) days after the applicable vesting date. Notwithstanding the foregoing, the Company may delay any payment under this Agreement that the Company reasonably determines would violate Applicable Laws until the earliest date the Company reasonably determines the making of the payment will not cause such a violation (in accordance with Treasury Regulation Section 1.409A- 2(b)(7)(ii)), provided the Company reasonably believes the delay will not result in the imposition of excise taxes under Section 409A. (b) (c) All distributions shall be made by the Company in the form of whole shares of Common Stock. Neither the time nor form of distribution of Shares with respect to the RSUs may be changed, except as may be permitted by the Administrator in accordance with the Plan and Section 409A of the Code and the Treasury Regulations thereunder. A-1 ARTICLE III. TAXATION AND TAX WITHHOLDING 3.1 Tax Withholding. (a) The Company shall not be obligated to deliver any certificate representing Shares issuable with respect to the RSUs to Participant or his or her legal representative unless and until Participant or his or her legal representative will have paid or otherwise satisfied in full the amount of all federal, state, local and foreign taxes required by Applicable Laws to be withheld in connection with the vesting, exercise or settlement of the RSUs, the distribution of the Shares issuable with respect thereto, or any other taxable event related to the RSUs (the “Tax Withholding Obligation”). Subject to Section 9.5 of the Plan, the Company will have the authority and the right to deduct or withhold, or require Participant to remit to the Company, an amount sufficient to satisfy any Tax Withholding Obligation, including, without limitation, the authority to deduct such amounts from other compensation payable to Participant by the Company. (b) Unless Participant elects to satisfy the Tax Withholding Obligation by some other means in accordance with Section 9.5 of the Plan, the Company will have the right, but not the obligation, with respect to the Tax Withholding Obligation arising as a result of the vesting, exercise or settlement of the RSUs, to treat Participant’s failure to provide timely payment in accordance with Section 9.5 of the Plan as Participant’s election to satisfy the Tax Withholding Obligation by requesting the Company to withhold a net number of vested Shares otherwise issuable pursuant to the RSUs having a then-current fair market value not exceeding the amount necessary to satisfy the Tax Withholding Obligation (provided that if Participant is subject to Section 16 of the Exchange Act, any such action by the Company will require the approval of the Administrator) in accordance with Section 9.5 of the Plan. 3.2 Participant Responsibility; No Company Liability. Participant acknowledges that Participant is ultimately liable and responsible for all taxes owed in connection with the RSUs, regardless of any action the Company or any Subsidiary takes with respect to any Tax Withholding Obligations that arise in connection with the RSUs. Neither the Company nor any Subsidiary makes any representation or undertaking regarding the tax treatment to Participant in connection with the awarding, vesting or settlement of the RSUs or the subsequent sale of Shares. The Company and its Subsidiaries do not commit and are under no obligation to structure the RSUs to reduce or eliminate Participant’s tax liability. 3.3 Representation. Participant represents to the Company that Participant has reviewed with Participant’s own tax advisors the tax consequences of this Award and the transactions contemplated by the Grant Notice and this Agreement. Participant is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. ARTICLE IV.
