CALGARY, Nov. 14, 2011 /CNW/ - Oncolytics Biotech Inc. ("Oncolytics")
(TSX:ONC, NASDAQ: ONCY) today announced that positive results from a
Phase 2 clinical trial (REO 015) using intravenous administration of
REOLYSIN® in combination with paclitaxel and carboplatin in patients with
advanced head and neck cancers will be presented at the AACR-NCI-EORTC
International Conference on Molecular Targets and Cancer Therapeutics.
The conference is being held in San Francisco, CA from November 12th to 16th 2011. The Principal Investigator of the U.S. study was Dr. Monica Mita
of the Cancer Therapy & Research Center at The University of Texas
Health Science Center at San Antonio (CTRC).
The U.S. trial was a single arm open-label, phase-2 study of REOLYSIN
given intravenously with paclitaxel (175 mg/m2) and carboplatin (AUC 5) every three weeks in patients with
platinum-refractory recurrent and/or metastatic squamous cell cancers
of the oral cavity, larynx, or pharynx. The primary end point was to
determine the objective response rate (complete response (CR) + partial
response (PR)) of the treatment regimen in the study population.
Secondary objectives included the determination of disease control rate
(CR + PR + stable disease (SD)) and the safety and tolerability of the
Of the 14 enrolled patients, all had received prior chemotherapy,
radiotherapy, or combinations thereof for their metastatic or recurrent
disease. Ten of the 14 patients received prior chemotherapy treatment
with taxanes. Of the 13 patients evaluable for response, four had PRs,
for an objective response rate of 31%. Six patients had SD or better
for 12 weeks or longer for a disease control rate (SD or better) of
46%. Two of the four patients with PRs and both patients with SD had
received prior treatment with taxanes.
"This study was undertaken as a confirmatory trial of an earlier study
performed in the UK with a similar patient population (REO 011). It
confirmed the high rate of responses observed in the U.K. study, and
was noteworthy as this U.S. patient population included a higher
proportion of patients that had failed prior taxane-based therapy,"
said Dr. Matt Coffey, COO of Oncolytics. "Historically, head and neck
cancer has been characterized by a very low rate of success in
treatment of patients who have already failed chemotherapy. Standard
second-line therapies for platinum refractory head and neck cancer
using currently approved cytotoxics have yielded 3 to 7% response rates1."
"These data further confirm the utility of REOLYSIN in this indication,
even in a heavily pre-treated patient population," said Dr. Brad
Thompson, President and CEO of Oncolytics. "These results are an
important step towards making this potential therapy available to head
and neck cancer patients, and represent a significant milestone for
