6:32AM Oncolytics Biotech announces progression free survival data for Phase 2 study of REOLYSIN in squamous cell lung cancer; of the evaluable patients who had more than one cycle of therapy, 23 (92%) exhibited overall tumour shrinkage (ONCY) 2.90 : Co announced that a poster presentation covering progression free survival (PFS) and final tumour response data from its U.S. Phase 2 single arm clinical trial in patients with squamous cell carcinoma of the lung using intravenous administration of REOLYSIN in combination with carboplatin and paclitaxel (REO 021), is being made today at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics. The conference is being held in Boston, MA from Oct 19-23.

The investigators reported that there were 25 evaluable patients, each of whom had received between two and 12 cycles of therapy. Of the evaluable patients who had more than one cycle of therapy, 23 (92%) exhibited overall tumour shrinkage. When evaluated for best response, which is the best percentage response recorded on study compared to baseline, 10 patients (40%) had partial responses, while a further 14 (56%) showed stable disease, and one (4%), had progressive disease. Using RECIST criteria to evaluate best overall response, 10 patients (40%) had partial responses, 12 (48%) showed stable disease and three (12%), had progressive disease. 31.8% of patients with sufficient follow up had a PFS greater than six months.
