Oncolytics Biotech® Inc. Announces Phase I Study in Pediatric Patients with Relapsed or Refractory Solid Tumors to be Conducted by the Children’s Oncology Group and Sponsored by the National Cancer Institute

CALGARY, Nov. 18 /PRNewswire-FirstCall/ – Oncolytics Biotech Inc. (“Oncolytics”)
(TSX:ONC, NASDAQ:ONCY) announced today that the Children’s Oncology
Group (COG) intends to conduct a Phase I trial of REOLYSIN® in combination with cyclophosphamide in pediatric patients with
relapsed or refractory solid tumors. The study will be conducted in
collaboration with the Cancer Therapy Evaluation Program, Division of
Cancer Treatment and Diagnosis, U.S. National Cancer Institute (NCI),
which is part of the National Institutes of Health, under its Clinical
Trials Agreement with Oncolytics. Oncolytics will provide clinical
supplies of REOLYSIN for this study. The study chair will be Dr. E.
Anders Kolb
of the Nemours/Alfred I. duPont Hospital for Children.

The study is an open label, multicentre, dose escalation Phase I study
of REOLYSIN in patients aged three to 21 years with relapsed or
refractory solid tumors. Patients will receive intravenous REOLYSIN on
days one through five of each 28-day treatment cycle. Some patients
will also receive oral cyclophosphamide on days one through 21.
Treatments repeat every 28 days for up to 12 cycles in the absence of
disease progression or unacceptable toxicity.

The primary objectives of the trial include estimating maximum tolerated
dose, and defining and describing the toxicities of REOLYSIN and
REOLYSIN plus oral cyclophosphamide in this patient population.
Secondary objectives include defining antitumor activity of REOLYSIN
within the confines of a Phase I study, evaluating the development of
neutralizing antibodies to REOLYSIN following intravenous
administration of REOLYSIN alone and in combination with
cyclophosphamide, and assessing the biologic activity of REOLYSIN.
After completion of study treatment, patients are to be followed up
periodically for up to one year.

“This trial builds on a range of completed preclinical work and clinical
studies in adult patients, including a U.K. Phase I clinical study
examining the use of REOLYSIN in conjunction with cyclophosphamide and
a U.S. Phase II clinical study in sarcoma using REOLYSIN as a
monotherapy,” said Dr. Brad Thompson, President and CEO of Oncolytics.
“It is very important to investigate the use of an agent in adults
prior to proceeding to use in pediatric patients. With the work in
adults well advanced, we can now move ahead in younger patients.”

Information on the study will be available at www.clinicaltrials.gov.
