Oncolytics Biotech(R) Inc. Announces Completion of Enrollment in Translational Clinical Trial Investigating REOLYSIN(R) in Patients with Metastatic Colorectal Cancer

February 23, 2011

CALGARY, Feb. 23 /PRNewswire-FirstCall/ – Oncolytics Biotech Inc. (“Oncolytics”) (TSX:
ONC) (NASDAQ: ONCY) announced today that enrollment has been completed
in a U.K. translational clinical trial investigating intravenous
administration of REOLYSIN in patients with metastatic colorectal
cancer prior to surgical resection of liver metastases (REO 013). The
principal investigator is Professor Alan Melcher of St. James’s
University Hospital and the trial is sponsored by the University of
Leeds, UK.

“The early results from this study reported in 2010 concluded that
reovirus can be successfully delivered specifically to colorectal liver
metastases following intravenous administration as a monotherapy,” said
Dr. Brad Thompson, President and CEO of Oncolytics. “This is supportive
of observations that REOLYSIN was active against metastatic liver
lesions in a number of different combination therapy studies.”

The trial was an open-label, non-randomized, single centre study of
REOLYSIN given intravenously to patients for five consecutive days in
advance of their scheduled operations to remove colorectal cancer
deposits metastatic to the liver. After surgery, the tumour and
surrounding liver tissue were assessed for viral status and anti-tumour
effects.

The primary objectives of the trial are to assess the presence,
replication and anti-cancer effects of reovirus within liver metastases
after intravenous administration of REOLYSIN by examination of the
resected tumour. Secondary objectives include assessing the anti-tumour
activity and safety profile of REOLYSIN, and monitoring the humoral and
cellular immune response to REOLYSIN.

Eligible patients included those with histologically proven colorectal
cancer, planned for potentially curative surgical resection of liver
metastases. A total of 10 patients were treated in the study. The
results are expected to be fully reported in 2011.
