Oncolytics Biotech® Announces Successful End-of-Phase 2 Meeting with FDA for REOLYSIN® in Metastatic Breast Cancer

Outcome supports focus on HR+/HER2- patient group that reported an
effective doubling of median overall survival from 10.8 to 21.0 months

CALGARY and SAN DIEGO, Sept. 18, 2017 /PRNewswire/ – Oncolytics Biotech® Inc. (TSX: ONC) (OTCQX: ONCYF) (Oncolytics or the Company), a biotech company developing REOLYSIN® (pelareorep) a first-in-class, intravenously delivered immuno-oncolytic virus that activates the innate and adaptive immune systems, today announced a successful End-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) for REOLYSIN in combination with paclitaxel, for the treatment of hormone receptor positive, HER2 receptor negative (HR+/HER2-) metastatic breast cancer (mBC) patients. The purpose of the meeting was to discuss the preclinical and clinical programs, including the design of the phase 3 registration study to support a future Biologics License Application (BLA) submission in the U.S.

“The FDA’s feedback and positive End-of-Phase 2 meeting outcome support our proposed target patient population of HR positive/HER2 negative metastatic breast cancer patients for our registration study,” said Dr. Matt Coffey, President and CEO of Oncolytics Biotech. “With statistically significant and clinically compelling overall survival data, Fast Track designation and now clear guidance from the FDA, we are focused on finalizing the adaptive study design that will include approximately four hundred patients with a pre-determined interim analysis. Importantly, the FDA provided guidance that if the study achieves its primary endpoint, then it will be the only study required for BLA approval.  The design of the study and this FDA guidance will also continue to drive our partnering process.”   

Oncolytics’ proposed target population for its phase 3 study of pelareorep is patients with HR+/HER2- mBC, which represents approximately 73 percent of metastatic breast cancer cases that have limited treatment options that offer survival benefit. Details of the pivotal phase 3 registration study will be made available following evaluation and completion of discussions with clinical advisors, European regulators and potentially partners.

About Metastatic Breast Cancer
Metastatic breast cancer, also known as advanced or Stage 4 breast cancer, has spread to other parts of the body.  Most commonly the lungs, liver, bones or brain.  The disease affects over 154,000 women in the United States and according to the American Cancer Society, has a five-year survival rate of just 22 percent. Significantly lower than stage 3, with a five-year relative survival rate of 72 percent and stage 2, with a five-year survival rate over 90 percent.
