Oncolytics Biotech Inc. Collaborators to Present Reovirus Research at American Association for Cancer Research Annual Meeting

CALGARY, March 13 /PRNewswire-FirstCall/ - Oncolytics Biotech Inc. announced that two abstracts covering preclinical work with reovirus are available today on the American Association for Cancer Research (AACR) website at www.aacr.org, and on the Oncolytics website at www.oncolyticsbiotech.com. Both presentations are scheduled to be delivered at the AACR Annual Meeting in San Diego, California April 12-16, 2008.

The first abstract, entitled “Targeting Multiple Myeloma with Oncolytic Viral Therapy” covers preclinical work using reovirus as a purging agent during autologous (harvested from the patient themselves) hematopoietic stem cell transplants for multiple myeloma. The results demonstrated that up to 70% of multiple myeloma cell lines tested showed reovirus sensitivity and reovirus induced cell death mediated through apoptosis. An oral presentation is scheduled to be delivered by Dr. Chandini Thirukkumaran of the Tom Baker Cancer Centre, Calgary, AB on Tuesday, April 15, 2008.

The second abstract, entitled “Radiation in Combination with Reolysin for Pediatric Sarcomas” 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. A poster presentation is scheduled to be delivered by Dr. Pooja Gidwani of the Albert Einstein College of Medicine, Bronx, New York on Tuesday, April 15, 2008.

“This exciting work highlights the potential of expanding the use of the reovirus to include being used as a purging agent during autologous blood stem cell transplants, as well as a treatment for childhood sarcomas,” said Dr, Matt Coffey, Chief Scientific Officer of Oncolytics.
