SAN DIEGO, May 05, 2022 (GLOBE NEWSWIRE) -- Oncternal Therapeutics, Inc. (Nasdaq: ONCT), a clinical-stage biopharmaceutical company focused on the development of novel oncology therapies, today provided a business update and reported financial results for the first quarter of 2022.

“In the first quarter, we continued to advance our robust pipeline towards important inflection points, including the planned initiation of our zilovertamab registrational Phase 3 study in patients with MCL in Q3 2022, the submission of an IND for our ROR1-targeting CAR-T cell therapy candidate ONCT-808 in mid-2022, and the execution of IND-enabling studies for ONCT-534, our DAARI product candidate that may address key resistance mechanisms in metastatic prostate cancer,” said James Breitmeyer, M.D., Ph.D., Oncternal’s President and CEO. “Substantial progress of our pipeline has been supported by solid collaborations with our partners and execution by our team, and is being carried out with a focus on prudent cash management. Very importantly, we narrowed our focus on hematological malignancies and prostate cancer, and deprioritized our ONCT-216 program, which helped extend our cash runway well into Q3 2023. We will continue to explore and evaluate all potential sources of capital to enable us to reach our milestones.”

Recent Highlights

• In January 2022, we announced that we reached consensus with the FDA on the design and major study details of the Phase 3 Study, ZILO-301, to treat patients with relapsed or refractory mantle cell lymphoma (MCL) with zilovertamab, an investigational anti-ROR1 monoclonal antibody, in combination with ibrutinib. The agency also provided positive feedback on the proposed key clinical and regulatory requirements of our development program for zilovertamab in patients with MCL.
• In April 2022, we established a clinical manufacturing agreement with the Dana-Farber Cancer Institute to conduct cGMP cell preparation and manufacturing activities for use in first-in-human studies of our ROR1-targeting CAR-T cell therapy candidate ONCT-808.
• In April 2022, we announced the deprioritization of further development of ONCT-216 and the discontinuation of enrollment in the Phase 1/2 study evaluating ONCT-216 in patients with relapsed or refractory Ewing sarcoma.
  

Expected Upcoming Milestones

• Zilovertamab, our ROR1 antibody program
  • Initiation of global registrational Phase 3 Study, ZILO-301, in the third quarter of 2022
  • Interim clinical data update for patients with MCL and CLL treated with zilovertamab plus ibrutinib in ongoing Phase 1/2 clinical study will be presented at the ASCO 2022 Annual Meeting
  • Initiation of Phase 1b investigator sponsored trial of zilovertamab plus docetaxel for patients with metastatic castration-resistant prostate cancer (mCRPC) in mid-2022
• ONCT-808, lead candidate in our autologous ROR1-targeted CAR-T cell therapy program
  • Investigational New Drug (IND) application submission in mid-2022
• ONCT-534, lead candidate in our DAARI program
  • IND-enabling GLP toxicology studies and GMP manufacturing initiated in the second quarter of 2022

First Quarter 2022 Financial Results
Our grant revenue was $0.7 million for the first quarter ended March 31, 2022. Our grant revenue is derived from a subaward under a grant from the California Institute for Regenerative Medicine (CIRM) to the University of California, San Diego and two research and development grant awards from the National Institutes of Health (NIH).

Our total operating expenses for the first quarter ended March 31, 2022 were $10.7 million, including $2.0 million in non-cash stock-based compensation expense. Research and development expenses for the quarter totaled $7.0 million, and general and administrative expenses for the quarter totaled $3.7 million. Net loss for the first quarter was $9.9 million, or a loss of $0.20 per share, basic and diluted.

As of March 31, 2022, we had approximately 49.4 million shares of common stock outstanding, $82.2 million in cash and cash equivalents and no debt. We believe these funds will be sufficient to fund our operations well into Q3 2023. Our cash guidance is subject to a number of assumptions, including those related to the severity and duration of the COVID-19 pandemic, and the pace of our research and clinical development programs, among other aspects of our business and the geopolitical environment.

About Oncternal Therapeutics
Oncternal Therapeutics 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 pursues drug development targeting promising, yet untapped biological pathways implicated in cancer generation or progression, focusing on hematological malignancies and prostate cancer. The lead clinical program is zilovertamab, an investigational monoclonal antibody designed to inhibit ROR1, a type I tyrosine kinase-like orphan receptor. Zilovertamab is being evaluated in a Phase 1/2 clinical trial in combination with ibrutinib for the treatment of patients with mantle cell lymphoma (MCL) and chronic lymphocytic leukemia (CLL), in investigator-initiated studies, including a Phase 2 clinical trial of zilovertamab in combination with venetoclax, a Bcl-2 inhibitor, in patients with relapsed/refractory CLL, and in a Phase 1b study of zilovertamab in combination with docetaxel in patients with metastatic castration-resistant prostate cancer (mCRPC). Oncternal is also developing ONCT-808, a chimeric antigen receptor T cell (CAR-T) therapy that targets ROR1, which is currently in preclinical development as a potential treatment for hematologic cancers and solid tumors. The early-stage pipeline also includes ONCT-534, a dual-action androgen receptor inhibitor (DAARI), that is in preclinical development as a potential treatment for castration resistant prostate cancer, including those with clinically important resistance to approved androgen receptor inhibitors.

Forward-looking statements are subject to risks and uncertainties inherent in Oncternal’s business, including risks associated with the clinical development and process for obtaining regulatory approval of Oncternal’s product candidates, such as potential delays in the commencement, enrollment and completion of clinical trials; we have not conducted head-to-head studies of zilovertamab in combination with ibrutinib compared to ibrutinib monotherapy and data from separate studies may not be directly comparable due to the differences in study protocols, conditions and patient populations; the risk that interim results of a clinical trial do not predict final results and that one or more of the clinical outcomes may materially change as patient enrollment continues, following more comprehensive reviews of the data, as follow-up on the outcome of any particular patient continues, and as more patient data become available; later developments with the FDA may be inconsistent with the minutes from the completed end of Phase 2 meeting, including that the proposed Study ZILO-301 that may not support registration of zilovertamab in combination with ibrutinib which is a review issue with the FDA upon submission of a BLA; and other risks described in Oncternal’s filings with the U.S. Securities and Exchange Commission. All forward-looking statements in this press release are current only as of the date hereof and, except as required by applicable law, Oncternal undertakes no obligation to revise or update any forward-looking statement, or to make any other forward-looking statements, whether as a result of new information, future events or otherwise.
