CALGARY, June 20, 2012 /CNW/ - Oncolytics Biotech Inc. ("Oncolytics")
(TSX: ONC) NASDAQ: ONCY) announced today that the Company's independent
Data Monitoring Committee (DMC) has reviewed the safety data for the
first stage of its Phase III trial of REOLYSIN in combination with
carboplatin and paclitaxel for the treatment of head and neck cancers
(REO 018). Based on the review of the safety data the DMC has
recommended that enrollment continue in the study.
"The safety data from the first stage of the Phase III study met our
expectations and confirms the positive safety data from our other
clinical studies using REOLYSIN," said Dr. Brad Thompson, President and
CEO of Oncolytics. "We will now focus our time and attention on
conducting the statistical analysis of the efficacy of the first
stage's patient population, which is forthcoming."
The study design stipulates that the study will proceed to full
enrollment in Stage 2 (ranging from 100 to 400 additional patients)
provided that the DMC concludes that safety data in Stage 1 is
acceptable for continuation to Stage 2, and an independent statistical
analysis of Progression-Free Survival (PFS, a measure of efficacy) in
Stage 1 predicts probability of success in Stage 2. The data collection
for this analysis is currently being performed.
The safety analysis was performed on the 80 patients enrolled in Stage 1
of the study, once every patient had sufficient follow up after
starting treatment on the study (six weeks). The statistical analysis
will be performed once every patient has had sufficient follow up after
starting treatment (12 weeks) to determine potential differences in PFS
between the control and test arms of the study.
The study is a randomized, two-arm, double-blind, multi-centre,
two-stage, adaptive Phase III trial assessing the intravenous
administration of REOLYSIN with the chemotherapy combination of
paclitaxel and carboplatin versus the chemotherapy alone in patients
with metastatic or recurrent squamous cell carcinoma of the head and
neck, or squamous cell cancer of the nasopharynx, who have progressed
on or after prior platinum-based chemotherapy. On April 2, 2012, the
Company announced that enrollment in the non-adaptive, 80-patient first
stage of the trial had been completed. Enrollment is currently underway
in the adaptive second stage, which is designed to enroll between 100
and 400 patients. This adaptive trial design allows data evolution to
determine if the probably of reaching a statically significant endpoint
has been achieved. The trial is currently being conducted at more than
80 centres in 14 countries in North America and Europe, including the
United States following an agreement with the U.S. Food and Drug
Administration (FDA) under the Special Protocol Assessment (SPA)
process with respect to the trial's design.
