Oncolytics Biotech® Announces Poster Presentation Demonstrating the Ability of REOLYSIN® to Promote and Predict Response to Checkpoint Inhibitors at ASCO 2018 Annual Meeting

CALGARY, Alberta and SAN DIEGO, June 04, 2018 (GLOBE NEWSWIRE) -- Oncolytics Biotech® Inc. (TSX:ONC) (NASDAQ:ONCY), currently developing REOLYSIN® (pelareorep), an intravenously delivered immuno-oncolytic virus turning cold tumors hot, today announced a key poster presentation at the American Society of Clinical Oncology (ASCO) 2018 Annual Meeting. The meeting takes place from June 1 - 5, 2018 at McCormick Place, Chicago, IL.

“These results demonstrate that pelareorep promotes the expression of gene signatures predictive of a response to immunotherapy in breast cancer and hepatocellular carcinoma,” said Matt Coffey, President and CEO of Oncolytics Biotech. “The tumor inflammation promoting effects in breast cancer models provide a compelling explanation for the significant overall survival benefit in hormone receptor positive metastatic breast cancer patients in our phase 2, IND 213, study and we believe this will continue to drive interest in our breast cancer program.”

Highlights of the poster include:

  • Pelareorep promotes expression of gene signatures that are predictive of response to checkpoint inhibitors in select cell lines
  • HCC   - hepatocellular carcinoma
  • HR+ BC    - hormone receptor positive breast cancer
  • Pronounced tumor inflammatory effects of pelareorep in HR+ BC cells may explain the prominent increase in overall survival in a previous phase 2 randomized clinical study in HR+ mBC patients treated with pelareorep and may render this large breast cancer population susceptible to conventional immunotherapy regimes

  • Results warrant further investigation of pelareorep in combination with checkpoint inhibitors
Presenter & Lead Author: Grey A. Wilkinson PhD, Oncolytics Scientist, Translational Medicine

About REOLYSIN/Pelareorep 
REOLYSIN, also known as pelareorep, is a non-pathogenic, proprietary isolate of the unmodified reovirus: a first-in-class intravenously delivered immuno-oncolytic virus for the treatment of solid tumors and hematological malignancies. The compound induces selective tumor lysis and promotes an inflamed tumor phenotype through innate and adaptive immune responses to treat a variety of cancers.

About Oncolytics Biotech Inc.
Oncolytics is a biotechnology company developing REOLYSIN®, also known as pelareorep, an intravenously delivered immuno-oncolytic virus. The compound induces selective tumor lysis and promotes an inflamed tumor phenotype -- turning "cold" tumors "hot" -- through innate and adaptive immune responses to treat a variety of cancers. Oncolytics' clinical development program emphasizes three pillars: chemotherapy combinations to trigger selective tumor lysis and immuno-therapy and immune modulator (IMiD) combinations to produce innate and adaptive immune responses. Oncolytics is currently planning its first registration study in metastatic breast cancer, as well as studies in combination with checkpoint inhibitors and targeted and IMiD therapies in solid and hematological malignancies.
