Oncolytics Biotech Inc. Announces Filing of Phase 1/2 Clinical Trial with REOLYSIN(R)

CALGARY, Jan. 3 /PRNewswire-FirstCall/ – Oncolytics Biotech Inc.
(“Oncolytics”) (TSX:ONC, NASDAQ:ONCY) announced today that the U.S. National
Cancer Institute (NCI) has filed a protocol with the U.S. Food and Drug
Administration (FDA) for a Phase 1/2 clinical trial for patients with
metastatic ovarian, peritoneal or fallopian tube cancers using concurrent
systemic and intraperitoneal administration of REOLYSIN(R), Oncolytics’
proprietary formulation of the human reovirus. The NCI is sponsoring the trial
under its Clinical Trials Agreement with Oncolytics, while Oncolytics will
provide clinical supplies of REOLYSIN(R).

The trial, which is being carried out at The Ohio State University
Comprehensive Cancer Center, is expected to enroll up to 70 patients with
metastatic ovarian, peritoneal or fallopian tube cancers.

These cancer indications were selected after comprehensive preclinical
studies carried out by the NCI indicated the reovirus can kill ovarian cancer
cells.

The American Cancer Society estimates that more than 22,000 women will be
diagnosed with ovarian cancer in the U.S. in 2007, and more than 15,000 will
die from it.
