Oncolytics Biotech Inc. Collaborators to Present Reovirus/Gemcitabine Combination Research at AACR Annual Meeting

CALGARY, March 13 /PRNewswire-FirstCall/ - Oncolytics Biotech Inc. (TSX: ONC, NASDAQ: ONCY) announced today that an abstract covering preclinical work using reovirus in combination with gemcitabine is available today on the American Association for Cancer Research (AACR) website at www.aacr.org, and on the Oncolytics website at www.oncolyticsbiotech.com. The abstract is entitled "In Vivo Synergy between Oncolytic Reovirus and Gemcitabine in Ras-Mutated Human HCT116 Xenografts." The combination of reovirus and gemcitabine was more effective than gemcitabine or reovirus alone at killing human colon cancer cells in a mouse model.

"This exciting work demonstrates that existing, approved chemotherapies like gemcitabine may enhance the anti-tumour activity of REOLYSIN(R), which has been demonstrated previously to be active in both animals and humans when used on its own," said Matt Coffey, Chief Scientific Officer. "Moreover, this important preclinical work supports our approved human clinical trial of this drug combination and provides additional evidence that combination treatment may lead to first-line therapy indications for REOLYSIN(R)."

A poster presentation covering more detailed information is scheduled to be delivered at the AACR annual meeting which runs April 14-18, 2007 in Los Angeles, CA. The poster will be delivered by Dr. Maureen E. Lane of the Division of Hematology and Medical Oncology and Director, Clinical Translational Research Core Laboratory at Weill Medical College of Cornell University, New York.
