Rare Pediatric Disease Designation received from FDA for TK216 for treatment of Ewing sarcoma
Interim Phase 1 data for TK216 in 15 evaluable patients with relapsed/refractory Ewing sarcoma demonstrated two complete responses, with no relapses after complete response
Strengthened the balance sheet by securing $10.1 million in equity financing during Q3 2020
SAN DIEGO, Nov. 04, 2020 (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 third quarter 2020 financial results.
“In the third quarter we continued advancing our oncology pipeline while strengthening our balance sheet,” said James Breitmeyer, M.D., Ph.D., President and CEO, Oncternal. “We expect to provide additional data updates on our clinical trials in patients with mantle cell lymphoma (MCL), Ewing sarcoma, and chronic lymphocytic leukemia (CLL) in the fourth quarter.”
In July 2020, we hosted a virtual scientific presentation on the current treatment landscape of MCL, along with a discussion of our cirmtuzumab MCL clinical data set, with Dr. Michael Wang, professor of Lymphoma & Myeloma at The University of Texas MD Anderson Cancer Center. A data update from our ongoing open-label Phase 1/2 clinical trial of cirmtuzumab in combination with ibrutinib that was presented at the American Society of Clinical Oncology (ASCO) 2020 Virtual Annual Meeting in May 2020 showed a 58% complete response (CR) rate and 83% overall best objective response rate (ORR) for patients with relapsed/refractory MCL, as of the April 30, 2020 data cut-off date. Cirmtuzumab is an investigational, potentially first-in-class humanized monoclonal antibody that binds with high affinity to a biologically important epitope on ROR1 (Receptor-tyrosine kinase-like Orphan Receptor 1).
In September 2020, we met with the U.S. Food and Drug Administration (FDA) and are in a dialogue with the FDA regarding potential accelerated approval pathways for cirmtuzumab plus ibrutinib in patients with relapsed/refractory MCL.
In September 2020, a data update from the ongoing open-label Phase 1 clinical trial of TK216 in patients with relapsed or refractory Ewing sarcoma was given as an oral presentation at the European Society for Medical Oncology (ESMO) Virtual Congress 2020. The presentation included interim data for 15 evaluable patients treated at the recommended Phase 2 dose as of the August 13, 2020 data cut-off date. Two of the 15 patients had achieved complete responses (CR), including one surgical CR. Both CRs were ongoing and the patients remained on treatment. Five patients had stable disease (SD), for a disease control rate (CR, partial response or SD) of 47%. TK216 is an investigational, potentially first-in-class, targeted small-molecule inhibitor of the E26 transformation-specific (ETS) family of oncoproteins.
In October 2020, we announced that the FDA granted Rare Pediatric Disease designation for TK216 for treatment of Ewing sarcoma.
In July and September 2020, we raised an aggregate of $10.1 million in net proceeds from a registered direct offering and an underwritten offering.
Expected Upcoming Milestones

Clinical data update for patients with HER2-negative breast cancer in the ongoing Phase 1b study in the first half of 2021
Preclinical data in additional ROR1 expressing tumors in the first half of 2021
ROR1 CAR-T program

Third Quarter 2020 Financial Results
Our grant revenue was $0.6 million for the third quarter ended September 30, 2020. Our grant revenue is derived from a sub-award under a grant from CIRM to UC San Diego, which was awarded to advance our Phase 1/2 clinical trial evaluating cirmtuzumab in combination with ibrutinib for the treatment of patients with MCL or CLL.
Our total operating expenses for the third quarter ended September 30, 2020 were $5.0 million. Research and development expenses for the quarter totaled $3.0 million, and general and administrative expenses for the quarter totaled $1.9 million. Net loss for the third quarter was $4.4 million, or a loss of $0.22 per share, basic and diluted.
As of September 30, 2020, we had $21.3 million in cash and cash equivalents. We believe our current funds will be sufficient to fund our planned operations into the second quarter of 2021. As of September 30, 2020, we had 22.3 million shares of common stock outstanding.
About Oncternal Therapeutics
Oncternal Therapeutics is a clinical-stage biopharmaceutical company focused on the development of novel oncology therapies for the treatment of cancers with critical unmet medical need. Oncternal focuses drug development on promising yet untapped biological pathways implicated in cancer generation or progression. The clinical pipeline includes cirmtuzumab, an investigational monoclonal antibody designed to inhibit the ROR1 pathway, a type I tyrosine kinase-like orphan receptor, that 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) and in an investigator-sponsored, Phase 1b clinical trial in combination with paclitaxel for the treatment of women with HER2-negative metastatic or locally advanced, unresectable breast cancer. The clinical pipeline also includes TK216, an investigational targeted small-molecule inhibitor of the ETS family of oncoproteins, that is being evaluated in a Phase 1 clinical trial for patients with Ewing sarcoma alone and in combination with vincristine chemotherapy. In addition, Oncternal has a program utilizing the cirmtuzumab antibody backbone to develop a CAR-T therapy that targets ROR1, which is currently in preclinical development as a potential treatment for hematologic cancers and solid tumors.
