Oncolytics Biotech® Inc. Announces First Quarter 2011 Results

CALGARY, May 12 /PRNewswire-FirstCall/ – Oncolytics Biotech Inc. (TSX: ONC, NASDAQ: ONCY)
(“Oncolytics” or the “Company”) today announced its financial results
and operational highlights for the quarter ended March 31, 2011.

“In order to maximize the future commercial potential for REOLYSIN®, we continue to expand and advance our clinical program through a
combination of our own trials and sponsored initiatives that allow us
to cost effectively expand the scope of our clinical work,” said Dr.
Brad Thompson, President and CEO of Oncolytics. “In the quarter we
reported positive results from multiple trials and our strengthened
balance sheet will enable us to expand the number of randomized studies
we are running in 2011.”

Selected Highlights

Since January 1, 2011 the Company has announced:

Clinical Trial Results

    --  Preliminary results from a U.S. Phase 2 clinical trial (REO 017) using
        intravenous administration of REOLYSIN in combination with gemcitabine
        (Gemzar®) in patients with advanced pancreatic cancer. Seventeen
        evaluable patients with pancreatic cancer were expected to be treated in
        the first stage and if three or more patients received clinical benefit,
        the study would then proceed to the next stage. This endpoint was met
        after six evaluable patients were enrolled;
    --  Completion of enrollment and interim data from a U.K. translational
        clinical trial (REO 013) investigating intravenous administration of
        REOLYSIN in patients with metastatic colorectal cancer prior to surgical
        resection of liver metastases. On initial histological analysis of the
        10 treated patients, there was evidence of selective delivery of virus
        to tumour versus normal liver and viral replication in the majority
        (seven) of patients;

Ongoing Clinical Program

    --  The opening of enrollment in a U.S. Phase 1 study of REOLYSIN in
        combination with FOLFIRI (Folinic Acid (leucovorin) + Fluorouracil
        (5-FU) + Irinotecan) in patients with oxaliplatin refractory/intolerant
        Kras mutant colorectal cancer (REO 022);
    --  Start of enrollment in a 2-Arm randomized Phase 2 study of carboplatin,
        paclitaxel plus REOLYSIN versus carboplatin and paclitaxel alone in the
        first line treatment of patients with recurrent or metastatic pancreatic
        cancer sponsored by the NCI;
    --  Completion of enrollment in a U.S. Phase 2 clinical trial using
        intravenous administration of REOLYSIN in combination with paclitaxel
        and carboplatin in patients with advanced head and neck cancers (REO
        015);

Financial

    --  Pursuant to the acceleration of the expiry date of those warrants issued
        on November 23, 2009, the Company received proceeds of approximately
        US$6.8 million resulting from the exercise of 1,943,000 warrants; and
    --  The exercise of 1,322,750 warrants, issued in connection with the
        financing that closed on November 8, 2010, providing the Company with
        proceeds of approximately $8.2 million.
