CALGARY, Nov. 6 /PRNewswire-FirstCall/ - Oncolytics Biotech Inc. (TSX:ONC, NASDAQ:ONCY) ("Oncolytics" or the "Company") today announced updated results from a Phase II study of intravenous REOLYSIN(R) in patients with sarcomas metastatic to the lung in a poster presentation at the 15th Annual Connective Tissue Oncology Society Meeting held in Miami Beach, Florida, from November 5th to 7th. The poster presentation, entitled "A Phase II Study of Intravenous REOLYSIN (Wild-type Reovirus) in the Treatment of Patients with Bone and Soft Tissue Sarcomas Metastatic to the Lung", was delivered by Dr. Kamalesh Sankhala, part of principal investigator Dr. Monica Mita's team at the Institute of Drug Development (IDD), the Cancer Therapy and Research Center at the University of Texas Health Science Center, (UTHSC), San Antonio, Texas.

The investigators reported that the treatment has been well tolerated to date, and that 19 of 44 evaluable patients experienced stable disease ranging from two to 20 months, resulting in a total clinical benefit rate (complete response + partial response + stable disease) of 43%. The response objective for the study was three or more patients having prolonged stabilization of disease (greater than 6 months) or better, for the agent to be considered. The trial exceeded its established objective with six patients experiencing stable disease for more than six months. Two patients have experienced stable disease for more than 19 months. One has synovial cell sarcoma that relapsed following surgery, while the other has Ewing's Sarcoma and had previously progressed following multiple treatments.

"We were very happy to participate in the study," said Dr. Mita. "REOLYSIN is a promising option for patients with sarcoma as shown by the results of this study. As a single agent the virus had a clinical benefit rate of 43% and it was very well tolerated. Further studies combining REOLYSIN with chemotherapy are contempl
