Oncolytics Biotech Inc. Completes Patient Enrolment In UK Phase I Systemic Administration Clinical Trial

CALGARY, June 5 /PRNewswire-FirstCall/ - Oncolytics Biotech Inc. ("Oncolytics") is pleased to announce that it has completed patient enrolment in the dose escalation portion of its U.K. Phase I systemic administration clinical trial investigating the use of REOLYSIN(R) to treat patients with advanced cancers. A total of 30 patients were treated in the trial at escalating frequency and dosage to a maximum daily dose of 1x10(11) TCID(50). A maximum tolerated dose (MTD) was not reached and the treatment appears to have been well tolerated by the patients.

Interim results of the trial, which were presented at the American Society of Clinical Oncology (ASCO) Annual Meeting on June 4, 2006 in Atlanta, Georgia, indicated that REOLYSIN(R) can be delivered systemically to various tumour types and cause virus-mediated tumour responses.

The primary objective of the Phase I trial is to determine the MTD, dose limiting toxicity (DLT), and safety profile of REOLYSIN(R) when administered systemically to patients. A secondary objective is to examine any evidence of anti-tumour activity. Eligible patients include 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. The principal investigator for the study is Dr. Johann de Bono of the The Royal Marsden NHS Foundation Trust and The Institute of Cancer Research, London.
