Oncolytics Biotech Inc. Commences Patient Enrolment in U.S. Phase II Sarcoma Clinical Trial

    CALGARY, June 27 /CNW/ - Oncolytics Biotech Inc. ("Oncolytics") (TSX:ONC,
NASDAQ:  ONCY) announced today that patient enrolment has commenced in its U.S.
Phase II trial to evaluate the intravenous administration of REOLYSIN(R) in
patients with various sarcomas that have metastasized to the lung. Patients
are being enrolled at the Montefiore Medical Center/Albert Einstein College of
Medicine in the Bronx, New York, the University of Michigan Comprehensive
Cancer Center in Ann Arbor, and the Cancer Therapy and Research Center,
Institute for Drug Development in San Antonio, Texas.
    "The initiation of this trial represents an important milestone for the
Company," said Dr. Brad Thompson, President and CEO of Oncolytics. "We are now
treating patients with advanced cancers in Phase II clinical trials in the
U.S. and the U.K., with additional Phase II trials expected to begin before
the end of the year. These trials are expected to yield information that will
guide the late stage clinical development program for REOLYSIN(R)."
    The trial (REO 014) is a Phase II, open-label, single agent study whose
primary objective is to measure tumour responses and duration of response, and
to describe any evidence of antitumour activity of intravenous, multiple dose
REOLYSIN(R) in patients with bone and soft tissue sarcomas metastatic to the
lung. REOLYSIN(R) will be given intravenously to patients at a dose of
3x10(10) TCID(50) for five consecutive days. Patients may receive additional
five-day cycles of therapy every four weeks for a maximum of eight cycles. Up
to 52 patients will be enrolled in the study.
    Eligible patients must have a bone or soft tissue sarcoma metastatic to
the lung deemed by their physician to be unresponsive to or untreatable by
standard therapies. These include patients with osteosarcoma, Ewing sarcoma
family tumours, malignant fibrous histiocytoma, synovial sarcoma, fibrosarcoma
and leiomyosarcoma.
    "There are very few treatment options for patients with bone or soft
tissue sarcomas," said Dr. Matt Coffey, Oncolytics' Chief Scientific Officer.
"Our decision to choose this indication is based on the observed activity of
REOLYSIN(R) against sarcomas in both preclinical and clinical studies."
