Oncolytics Biotech Inc. Meets Primary Overall Statistical Endpoint in U.S. Phase 2 Study of REOLYSIN® in Squamous Cell Lung Cancer
Published: Mar 28, 2013
CALGARY, March 28, 2013 /PRNewswire/ - Oncolytics Biotech Inc. ("Oncolytics" or the "Company") (TSX:ONC) (NASDAQ: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% and a disease control rate (complete response (CR) + PR + SD) of 85.7%.
"We are pleased to have met the response rate endpoint, which builds on the data we announced from the first stage of this study," said Dr. Brad Thompson, President and CEO of Oncolytics. "Based on the positive data seen to date, we intend to conduct further studies in this indication."
The secondary objectives of the trial, for which data has yet to be released, are to assess progression-free survival and overall survival for the treatment regimen in the study population; to determine the proportion of patients receiving the above treatment who are alive and free of disease progression at six months; and to assess the safety and tolerability of the treatment regimen in the study population.
About SCC Lung Cancer
The American Cancer Society estimates that in 2013, approximately 228,190 new cases of lung cancer will be diagnosed. Between 85% and 90% of all lung cancers are classified as non-small cell lung cancer (NSCLC); squamous cell carcinomas (SCC) account for 25-30% of all lung cancers. 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 2013, accounting for around 27% of all cancer deaths. Lung cancer is the leading cause of cancer death, with more people dying each year of lung cancer than from colon, breast, and prostate cancers combined.
