Oncolytics Biotech Inc. Collaborators to Present Combination REOLYSIN(R) and Docetaxel Results at iSBTc Annual Meeting

October 23, 2008

CALGARY, Oct. 23 /PRNewswire-FirstCall/ — Oncolytics Biotech Inc. (TSX: ONC, NASDAQ: ONCY) announced today that an abstract entitled “A Phase I Study to Evaluate Systemic Wild-Type Reovirus (REOLYSIN(R)) in Combination with Docetaxel in Patients with Advanced Malignancies” will be available in the November/December issue of the Journal of Immunotherapy, the official journal of the International Society for Biological Therapy of Cancer (iSBTc). The principal investigator for the trial is Professor Hardev Pandha of the Royal Surrey County Hospital, U.K.

The abstract covers results of the trial (REO 010) up to July 2008. Of the 12 patients treated at the time, three had completed six cycles, one further patient was still on treatment at cycle 7 and four others were ongoing between cycle 1 and cycle 4. Five patients remained on study. The researchers observed one complete resolution of the target lesion in a breast cancer patient with stable disease (SD) of non-target lesions; one partial response in gastric cancer; two SD in lung cancer; and, one SD in melanoma. The researchers concluded that REOLYSIN(R) can be safely combined with docetaxel, that there was objective radiological evidence of anticancer activity and that Phase II studies with this combination are justified. Any significant toxicities observed were consistent with those expected with docetaxel alone.

A poster presentation which will include current results of the trial is scheduled to be presented by Prof. Pandha on November 1, 2008 at the iSBTc annual meeting. The meeting is being held in San Diego, California from October 31-November 2, 2008.

Prof. Pandha is also scheduled to make a poster presentation on NovemberӚÓš 1, 2008 at the iSBTc meeting entitled “Synergistic Anti-Tumour Activity of Oncolytic Reovirus and Docetaxel in a PC-3 Prostate Cancer Mouse Model.” This preclinical research, which demonstrated that combining reovirus and docetaxel treatment resulted in markedly reduced tumour growth compared to single agent treatments, provided support for the ongoing U.K. clinical trial examining the combination of REOLYSIN(R) and docetaxel in patients with advanced cancers. An abstract covering these preclinical results will also be available in the November/December issue of the Journal of Immunotherapy.

Poster presentations will be available on the Oncolytics website at http://www.oncolyticsbiotech.com/ after they have been presented at the conference.
