Oncolytics Phase 2 Study of REOLYSIN Meets Primary Endpoint in Squamous Cell Lung Cancer

Oncolytics Biotech ONCY today announced that it has met the primary overall statistical endpoint in its U.S. Phase 2 single arm clinical trial in patients with squamous cell carcinoma of the lung (SCCLC) using intravenous administration of REOLYSIN in combination with carboplatin and paclitaxel in patients with metastatic stage IIIB, or stage IV, or recurrent SCCLC who are chemotherapy naïve for their metastatic or recurrent cancer (REO 021). The study is a two-stage design with a primary overall endpoint of objective tumor response rate. The Company saw a sufficient number of responses in the first stage of the study to proceed with enrollment in the second stage. A total of up to 36 patients were to be studied in the second stage. The primary endpoint was met if nine or more patients in both stages combined had a partial response (PR) or better, which yields a true response rate of 35% or more. This endpoint was met after 21 evaluable patients were treated on study, nine of which exhibited PRs, while a further nine showed stable disease (SD) and three, progressive disease (PD), for a response rate of 42.8% See full press release
