CALGARY, Alberta, February 23, 2011 - 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
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

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.
