SAN DIEGO, Jan. 28, 2021 (GLOBE NEWSWIRE) -- Oncternal Therapeutics, Inc. (Nasdaq: ONCT), a clinical-stage biopharmaceutical company focused on the development of novel oncology therapies, today announced the appointment of Rosemary Mazanet, M.D., Ph.D., to its Board of Directors, effective January 27, 2021. Dr. Mazanet has extensive experience in all stages of oncology drug development from investigational new drug submission ("IND") through new drug application ("NDA") approval and commercial launch.

"Dr. Mazanet brings deep expertise in oncology drug development and commercialization to the Board of Directors. Her broad experience in oncology drug development and commercialization will be a significant asset to Oncternal as we advance our cirmtuzumab, ROR1 CAR-T and TK216 programs for patients with cancer," said James Breitmeyer, M.D., Ph.D., Oncternal's President and CEO.

Dr. Mazanet trained in Internal Medicine and Oncology at the Brigham and Women's Hospital/Dana Farber Cancer Institute before starting her industry career at Amgen as the head of Clinical Research. At Amgen, Rosemary was given broad responsibilities as one of the first U.S. trained clinician scientists in her field, where she led multiple successful product development initiatives (4 INDs and sBLAs, one BLA, CE mark and IDE) including FDA panel presentations. After Amgen, Rosemary moved into public equity and joined Oracle Partners LLC in New York. Since that time, she has been a presence in public and private equity biotech and specialty pharma investments, most recently as a General Partner of Apelles Investment Management. She is currently the Chair of the Scientific Advisory Board and Chief Science Officer at Columbia Care, Inc. In addition to serving as a life sciences management and investment professional, Rosemary has served as a C-suite executive at several biopharma companies and led development programs ranging from IND submission through NDA approval and commercial launch. Among the many boards she is on, Rosemary is a Charter Trustee at the University of Pennsylvania School of Medicine and is the Chair of the Leonard Davis Institute Executive Advisory Board at Wharton.

"Oncternal is making great progress advancing the ROR1 antibody cirmtuzumab for patients with hematological cancers and solid tumors," said Dr. Mazanet. "In addition, Oncternal's ROR1 CAR-T program and its TK216 ETS transcription factor inhibitor hold significant promise for transforming lives of patients with difficult to treat cancers. I am excited to be joining the Board during such an exciting time for the company."

About Oncternal TherapeuticsOncternal 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.
