CALGARY, Feb. 14 /CNW/ - Oncolytics Biotech Inc. ("Oncolytics")
(TSX:ONC, NASDAQ: ONCY) today announced 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. The trial is being
conducted at the Cancer Therapy & Research Center at The University of
Texas Health Science Center at San Antonio (CTRC). The Principal
Investigator is Dr. Monica Mita of the CTRC.
"When we opened the study we anticipated positive results based on
preclinical models and on the high frequency of Ras pathway
abnormalities in pancreatic cancer," said Dr. Monica Mita. "We are,
however, impressed by the fact that the study met the endpoint so
early. We are eager to complete the study and to proceed to the next
step of development for this combination."
The trial is a single arm, open-label, Phase 2 study of REOLYSIN given
intravenously with gemcitabine every three weeks. The study's primary
objective is to determine the clinical benefit rate (complete response
(CR) + partial response (PR) + stable disease (SD)) of REOLYSIN in
combination with gemcitabine in patients with advanced or metastatic
pancreatic adenocarcinoma with measurable disease who have not received
any prior chemotherapy or biotherapy. The secondary objectives are to
determine progression-free survival, and the safety and tolerability of
REOLYSIN when administered in combination with gemcitabine. 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. All patients
treated reported symptomatic improvement. Three of six patients showed
SD for 12 weeks or greater. In addition, one patient had stable disease
at nine weeks of treatment, but was taken off of the study for
alternative treatment, and one patient had a PR of less than 12 weeks
duration, and then died from a medical issue unrelated to treatment.
The Company now intends to complete enrollment in the first stage of
the study and then continue with further studies.
"This study is supportive of the decision to conduct the randomized
Phase II study being sponsored by the NCI examining REOLYSIN in
combination with carboplatin/paclitaxel," said Dr. Brad Thompson,
President and CEO of Oncolytics.
