Oncolytics Biotech® Inc. Announces Phase I Multiple Myeloma Cancer Study

CALGARY, May 10 /PRNewswire/ - Oncolytics Biotech Inc. ("Oncolytics") (TSX:ONC, NASDAQ:ONCY) announced today that the Cancer Therapy Evaluation Program, Division of Cancer Treatment and Diagnosis, U.S. National Cancer Institute (NCI), which is part of the National Institutes of Health, has agreed to sponsor a Phase I study of REOLYSIN^® alone in patients with relapsed multiple myeloma. The NCI is sponsoring the trial under its Clinical Trials Agreement with Oncolytics, while Oncolytics will provide clinical supplies of REOLYSIN. The Principal Investigator is Dr. Craig Hofmeister of The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute.

"While progression free survivals have improved with novel therapies over the last decade, the cure fraction remains low and additional options are needed," said Dr. Craig Hofmeister, principal investigator. "Multiple myeloma cells are frequently RAS activated, especially in relapse, so we are very interested in looking at REOLYSIN for these patients."

The study will initially be a proof of concept, open-label Phase I study of REOLYSIN in patients with relapsed multiple myeloma.  Approximately 12 patients will receive REOLYSIN, in a dose escalation up to 3 x 10¹⁰ TCID₅₀ per day administered intravenously on days one through five every 28 days.

The primary endpoint for the dose escalation portion of this study will be adverse events using CTCAE criteria.  Correlative studies will focus on the efficiency with which reovirus replicates in patient myeloma cells. Investigators will use standard cohorts-of-three phase I dose escalation design with three to six patients being treated at each dose level.  Secondary endpoints will include clinical benefit, duration of response, and time to progression.

This is the sixth clinical trial using REOLYSIN to be sponsored by the NCI.  The NCI is currently conducting a Phase II metastatic melanoma trial, a Phase I/II and a randomized Phase II ovarian, peritoneal and fallopian tube cancer trials, a randomized Phase II trial in pancreatic cancer and a Phase I trial in pediatric patients with relapsed or refractory solid tumors.
