FOR IMMEDIATE RELEASE
Oncolytics Biotech Inc. Announces
Positive Clinical Data from U.S. Phase I REOLYSIN
® Trial
CALGARY, AB, — June 5, 2007 - Oncolytics Biotech Inc. (“Oncolytics”) (TSX:ONC, NASDAQ:ONCY) announced today positive results from its U.S. Phase I clinical trial examining the systemic administration of REOLYSIN® in patients with advanced cancers. The results indicate that REOLYSIN® can be delivered systemically to patients with advanced and metastatic cancers and cause anti-tumour activity.
“REOLYSIN® administered as a one-hour infusion on a monthly schedule is safe and well-tolerated even in multiple doses,” said Principal Investigator Dr. Sanjay Goel of the Montefiore Medical Center and Albert Einstein College of Medicine, New York. “This preliminary data suggests there is anti-tumour activity of REOLYSIN® administered as a single agent, and warrants further studies either alone or in combination with cytotoxic chemotherapy, which are currently being planned.”
A total of 18 patients were treated in the escalating dosage trial to a maximum daily dose of 3x1010 TCID50 in a one-hour infusion. Of the 18 patients treated, eight demonstrated stable disease as measured by RECIST (Response Evaluation Criteria in Solid Tumours) including a patient with progressive breast cancer who experienced a 28.5% shrinkage in tumour volume. The trial was originally designed to demonstrate the safety of a single, one-hour infusion of REOLYSIN®. During the treatment of the 4th cohort of patients however, Oncolytics applied for and was granted approval to allow subsequent patients to receive repeat monthly treatments of REOLYSIN®. Of the patients eligible for retreatment, three patients received a range of two to seven one-hour infusions of REOLYSIN®.
Toxicities possibly related to REOLYSIN® treatment in this trial were generally mild (grade 1 or 2) and included chills, fever and fatigue.
The primary objective of the Company’s U.S. Phase I trial is to determine the maximum tolerated dose, (MTD), dose limiting toxicity (DLT), and safety profile of REOLYSIN® when administered systemically to patients. A secondary objective is to examine any evidence of anti-tumour activity. Eligible patients included those who had been diagnosed with advanced or metastatic solid tumours that are refractory (have not responded) to standard therapy or for which no curative standard therapy exists.
