Oncolytics Biotech® Inc. Collaborators Present Preclinical Data on the Combination of REOLYSIN® and Radiotherapy in Melanoma at the Irish Association for Cancer Research Conference

CALGARY, March 5, 2015 /PRNewswire/ - Oncolytics Biotech^® Inc. ("Oncolytics") (TSX:ONC) (NASDAQ:ONCY) today announced that an oral presentation by the Company's research collaborators in Professor Kevin Harrington's lab at the Institute for Cancer Research, titled "Synergistic Combination of Oncolytic Reovirus Type 3 (Dearing) and Radiotherapy in Melanoma is Mediated Through Enhanced Viral Replication and Mitochondrial Apoptotic Signaling," was made at the Irish Association for Cancer Research (IACR) Conference held  in Limerick, Ireland.

"Malignant melanoma is typically resistant to traditional chemotherapeutic and radiotherapy regimens," said Dr. Matt Coffey Chief Operating Officer of Oncolytics. "This preclinical research highlights the synergistic role REOLYSIN^® could play in making traditional treatments, such as radiotherapy, more effective."

The Company's research collaborators presented data from a variety of melanoma models. They concluded that the combination of REOLYSIN^® and radiation therapy enhances cytotoxicity in those cell lines by increasing programmed cancer cell death, and that radiation therapy supports increased reovirus replication and suppresses the host cell's anti-viral defenses.

This builds on a recent publication by Professor Harrington's group that demonstrated that REOLYSIN^® could act synergistically in combination with a new class of targeted agents to treat skin cancers with a specific mutation. The work, titled "BRAF- and MEK-Targeted Small Molecule Inhibitors Exert Enhanced Antimelanoma Effects in Combination with Oncolytic Reovirus Through ER Stress," was published recently in the online version of Molecular Therapy. The publication outlined how the combination of REOLYSIN^® and BRAF inhibitors improved survival in mouse models compared to either agent alone. This adds to the body of research on how REOLYSIN^® can act synergistically with targeted agents on tumours with mutations along the Ras-signaling pathway.
