CALGARY, Canada, April 15 /PRNewswire/ -- Oncolytics Biotech Inc. (TSX: ONC) (NASDAQ: ONCY) announced that a poster presentation by Dr. Anders Kolb of the Nemours Center for Childhood Cancer Research entitled "Radiation in Combination with Reolysin for Pediatric Sarcomas" was presented today at the American Association for Cancer Research (AACR) Annual Meeting. The meeting is being held in San Diego, California from April 12-16, 2008.

"The combination of REOLYSIN(R) with radiation is certainly favourable," said Dr. Kolb. "Statistically significant improvements in event-free survival are seen in mice treated with the combination when compared to either therapy alone."

The poster covers preclinical work using reovirus in combination with radiation in mice implanted with pediatric rhabdomyosarcoma and Ewing's sarcoma tumours. The results demonstrated that the combination of reovirus and radiation significantly enhanced efficacy compared to either treatment alone in terms of tumour regression and event-free survival.

"We are very pleased to be working with investigators such as Dr. Kolb," said Dr. Matt Coffey, Chief Scientific Officer of Oncolytics. "The work completed by Dr. Kolb and his team supports our ongoing efforts in our human trials with REOLYSIN(R)."

The poster will be available on the Oncolytics website today at http://www.oncolyticsbiotech.com
