Oncolytics Biotech Inc. Announces U.S. Phase 2 Clinical Trial Investigating REOLYSIN(R) in Combination with Paclitaxel and Carboplatin

CALGARY, June 20 /PRNewswire-FirstCall/ – Oncolytics Biotech Inc.
(“Oncolytics”) (TSX:ONC, NASDAQ:ONCY) announced today that following U.S. Food
and Drug Administration (FDA) review, the Company is initiating a U.S. Phase 2
clinical trial using intravenous administration of REOLYSIN(R) in combination
with paclitaxel and carboplatin in patients with advanced head and neck
cancers. The Principal Investigator is Dr. Monica Mita of the Cancer Therapy
and Research Center, University of Texas Health Science Center in San Antonio,
Texas (CTRC at UTHSCSA).

“REOLYSIN(R) is one of the more exciting targeted agents under development
in oncology,” said Dr. Frank Giles, Director of the Institute for Drug
Development. “Our investigators within the CTRC at UTHSCSA are very excited to
begin studying potential synergy with standard cytotoxic agents and are eager
to expand our studies into other tumor types and utilizing other chemotherapy
partner regimens.”

This trial is a 14-patient, single arm, open-label, dose-targeted,
non-randomized trial of REOLYSIN(R) given intravenously in combination with a
standard dosage of paclitaxel and carboplatin.

Eligible patients include those with advanced or metastatic head and neck
cancers that are refractory to standard therapy or for which no curative
standard therapy exists. The primary objective of the Phase 2 trial is to
measure tumour responses and duration of response, and to describe any
evidence of antitumour activity. The secondary objective is to determine the
safety and tolerability of REOLYSIN(R) when administered in combination with
paclitaxel and carboplatin to patients with advanced or metastatic head and
neck cancers.
