CALGARY, Feb. 8, 2013 /PRNewswire/ - Oncolytics Biotech Inc. ("Oncolytics") (TSX: ONC) (NASDAQ: ONCY) today announced results examining percent overall tumour shrinkage data from its U.S. Phase 2 clinical trial in patients with squamous cell carcinoma of the lung (SCCLC) using intravenous administration of REOLYSIN® in combination with carboplatin and paclitaxel (REO 021).
The analysis examined percent best overall tumour changes between pre-treatment and up to six treatment cycles. Of 20 evaluable patients, 19 (95%) exhibited overall tumour shrinkage, (mean (20 patients): 33.7% shrinkage). A waterfall graph showing individual patient data will be available on the Company's website at http://www.oncolyticsbiotech.com/presentations.
"It's exciting to have 95% of patients in this study exhibit tumour shrinkage and these results further suggest that REOLYSIN may have potential use in neoadjuvant (pre-surgical) settings," said Dr. Brad Thompson, President and CEO of Oncolytics. "Based on these findings we intend to continue to look at REOLYSIN as a treatment for cancers of the lung and cancers that metastasize to the lung."
The study enrolled patients with metastatic or recurrent squamous cell carcinoma of the lung. The primary endpoint of the study is objective tumour response rates, and the secondary objectives include progression free survival and overall survival. To date, the Company has observed nine partial responses (PR), nine stable disease (SD) and three progressive disease (PD) by RECIST criteria for a disease control rate (complete response (CR) + PR + SD)) of 86%. The study continues to enroll patients.
About SCC Lung Cancer
The American Cancer Society estimates that in 2013, approximately 228,190 new cases of lung cancer will be diagnosed.

Lung cancer is by far the leading cause of cancer death among both men and women. There will be an estimated 159,480 deaths from lung cancer in the United States in 2012, accounting for around 27% of all cancer deaths.
