SAN DIEGO, Calif. and CALGARY, Canada — Oncolytics Biotech® Inc. (NASDAQ: ONCY) (TSX: ONC), a leading clinical-stage company specializing in immunotherapeutics for oncology, is pleased to announce the submission of a Type C meeting request to the FDA. This meeting aims to discuss the Company’s planned registration-enabling trial for pelareorep in HR+/HER2- metastatic breast cancer (mBC).
“A key focus for Oncolytics in 2024 is defining the regulatory path for pelareorep in breast cancer treatment. We are optimistic that pelareorep, in combination with paclitaxel, could significantly enhance clinical outcomes for patients with HR+/HER2- metastatic breast cancer. Our position is strengthened by encouraging data from two randomized studies (BRACELET-1 and IND-213) and the AWARE-1 study, paving the way for the next phase of pelareorep’s development and its registration. Ongoing discussions with our clinical collaborators and partners have helped us to prepare a robust, compelling briefing document,” said Dr. Matt Coffey, President and Chief Executive Officer of Oncolytics. “We eagerly anticipate our discussion with the FDA to align on the design and objectives of the registrational trial for pelareorep in metastatic breast cancer, a critical step towards bringing this innovative treatment to patients. Having a well-defined plan for the registrational track study will also help advance our strategic partnering discussions. We hope to meet with the agency in Q2 2024 and look forward to a productive dialogue. With anticipated overall survival data from the BRACELET-1 study and productive discussions with the FDA, 2024 is poised to be a transformative year for Oncolytics and our stakeholders.”
Thomas Heineman, M.D., Ph.D., Chief Medical Officer at Oncolytics, added, “The data from the randomized BRACELET-1 trial showcased compelling results for the pelareorep/paclitaxel combination therapy in HR+/HER2- metastatic breast cancer patients, with a nearly tripled confirmed response rate, a 50% improvement in median progression-free survival, and a hazard ratio of 0.29 compared to the paclitaxel alone control. Importantly, these data support the statistically significant near doubling of median overall survival in another randomized phase 2 study, IND-213, which also evaluated pelareorep and paclitaxel in HR+/HER2- metastatic breast cancer patients.”
Dr. Heineman continued, “Our proposed study plans to evaluate pelareorep in patients with HR+/HER2- mBC who are eligible for chemotherapy after progressing on prior hormonal therapy, including a CDK 4/6 inhibitor. We also intend to evaluate potential biomarkers, including the expansion of tumor-infiltrating lymphocytes, using T cell receptor sequencing. We look forward to the opportunity to discuss our plans with the agency and align on the best approach to advance the development of pelareorep as a potential treatment option to improve outcomes for breast cancer patients.”
About Oncolytics Biotech Inc.
Oncolytics is a clinical-stage biotechnology company developing pelareorep, an intravenously delivered immunotherapeutic agent. Pelareorep has demonstrated promising results in Phase 2 studies in breast and pancreatic cancers. It acts by inducing anti-cancer immune responses and promotes an inflamed tumor phenotype — turning “cold” tumors “hot” — through innate and adaptive immune responses to treat a variety of cancers.
Pelareorep has demonstrated synergies with multiple approved oncology treatments. Oncolytics is currently conducting and planning combination clinical trials with pelareorep in solid and hematological malignancies as it advances towards registrational studies in metastatic breast cancer and pancreatic cancer, both of which have received Fast Track designation from the FDA.
