CALGARY, AB, May 18 /PRNewswire-FirstCall/ - Oncolytics Biotech Inc. ("Oncolytics") (TSX:ONC, NASDAQ:ONCY) announced today that a paper entitled "Two-Stage Phase I Dose-Escalation Study of Intratumoural Reovirus Type 3 Dearing and Palliative Radiotherapy in Patients with Advanced Cancers," has been published in the online version of the journal Clinical Cancer Research.
The paper covers final results from a Phase Ia/Ib U.K. clinical trial (REO 006) investigating the intratumoural delivery of REOLYSIN(R) in combination with radiation to treat patients with advanced cancers. A total of 23 patients received a range of two to six intratumoural doses of REOLYSIN at escalating dosages up to a maximum of 1x10(10) TCID(50) with a constant localized radiation dose of either 20 Gy or 36 Gy. The principal investigator for the study is Dr. Kevin Harrington from The Institute of Cancer Research and The Royal Marsden Hospital, London, U.K.
Of the seven evaluable patients in the low-dose (20Gy) radiation group, two patients had a partial response (PR) (esophageal adenocarcinoma and squamous cell carcinoma (SCC) of the skin) and five had stable disease (SD) including patients with malignant melanoma, pancreatic adenocarcinoma, SCC of the larynx and SCC of the skin (2). In the high-dose (36Gy) radiation group, five of seven evaluable patients had PRs (malignant melanoma (2), lung adenocarcinoma, colorectal adenocarcinoma, and ovarian adenocarcinoma) and two had SD (malignant melanoma).
"All 14 patients considered evaluable for treatment response in this study had SD or better for a clinical benefit rate of 100%," said Dr.
