Oncolytics Biotech® Inc. Announces 2013 Year End Results

CALGARY, March 13, 2014 /PRNewswire/ - Oncolytics Biotech Inc. (TSX:ONC, NASDAQ:ONCY) ("Oncolytics" or the "Company") today announced its financial results and operational highlights for the year ended December 31, 2014.

"In 2013, we reported data from a number of clinical studies, which included our first data correlating specific biomarkers with survival in NSCLC lung cancer patients and culminated with the reporting of our first randomized data in head and neck cancer," said Dr. Brad Thompson, President and CEO of Oncolytics. "Our randomized clinical program continues to move ahead with six sponsored studies currently enrolling patients in a range of indications. Each of these studies will advance in parallel with our ongoing head and neck program which we are currently in the process of designing a follow-on registration study for discussion with regulators."

Selected Highlights

Since January 1, 2013, specific highlights announced by the Company include:

Clinical Trial Results

• Top-line data for the endpoints in a double blinded, randomized clinical study examining REOLYSIN^® in combination with carboplatin and paclitaxel in patients with second-line platinum-refractory, taxane-naïve head and neck cancers (REO 018). An analysis was performed on an intent-to-treat basis of 118 patients with loco-regional head and neck cancer, with or without metastases. Patients in the control arm were treated with carboplatin and paclitaxel, while patients in the test arm were treated with carboplatin, paclitaxel and REOLYSIN. The analysis showed a median progression free survival (PFS) of 94 days (13.4 weeks) in the test arm (n=62), versus 50 days (7.1 weeks) in the control arm (n=56). The test arm maintained a PFS benefit over the control arm through five cycles of therapy. An analysis of 88 loco-regional patients that did not receive additional therapy following discontinuation of study treatment showed a median overall survival (OS) of 150 days (21.4 weeks) in the test arm (n=50), versus 115 days (16.4 weeks) in the control arm (n=38). REOLYSIN was deemed safe and well-tolerated by patients. The side effects experienced by patients in the test arm of the study were consistent with expectations based on outcomes of earlier clinical studies using REOLYSIN. Patients on the test arm of the study experienced a higher incidence of flu-like symptoms consistent with treatment with a virus, most commonly mild fever, chills, nausea and diarrhea, on both a per-patient and a per-cycle basis. Fewer patients required dose reductions of paclitaxel due to neuropathy or neurotoxicity on the test arm than the control arm (zero in the test arm versus six in the control arm; p=0.028). On this basis, the Company intends to explore the potential chemoprotective and neuroprotective properties of REOLYSIN in future clinical studies;

• Positive final results from a U.S. Phase 2 study examining the use of REOLYSIN in combination with carboplatin and paclitaxel in patients with stage IV non-small cell lung cancer (NSCLC) with Kras or EGFR-activated tumors (REO 016). Response evaluation for 36 evaluable patients showed 11 partial responses (PR) (30%) (EGFR amplified, five; BRAF two; Kras, three; EGFR mutated, one), 21 stable disease (SD), and four progressive disease (PD). The data also correlated a number of molecular abnormalities with best response, PFS and one-year survival. Current data in these patients demonstrates that 20 of 36 evaluable patients (56%) survived a year or more. There were 13 patients with only EGFR mutations or amplifications, of whom nine (69.2%) survived a year or longer. Four of four (100%) patients with BRAF and EGFR amplification survived a year or longer;

• Final tumor response and PFS data from a 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). Of the 25 evaluable patients who had more than one cycle of therapy, 23 (92%) exhibited overall tumor shrinkage. When evaluated for best response, which is the best percentage response recorded on study compared to baseline, 10 patients (40%) had PR, while a further 14 (56%) showed SD, and one (4%), had PD. Using RECIST criteria to evaluate best overall response, 10 patients (40%) had PRs, 12 (48%) showed SD and three (12%), had PD.  31.8% of patients with sufficient follow up had a PFS greater than six months;

• Reaching the stage 1 endpoint in a U.S. Phase 2 clinical trial in patients with metastatic melanoma (REO 020) after only 14 patients were enrolled.  The primary objective of this Phase 2 trial was to assess the antitumor effect of the treatment regimen in the study population in terms of objective response rates. The secondary objectives were to assess progression-free survival and overall survival for the treatment regimen; the disease control rate (complete response (CR) plus PR plus SD) and duration, and to assess the safety and tolerability of the treatment regimen in the study population.  Three of the 14 patients exhibited a PR, and an additional seven patients had SD for a disease control rate of 71.5%; and

• Positive preliminary results from a Phase 1 study examining the intravenous administration of REOLYSIN in combination with FOLFIRI in patients with metastatic colorectal cancer (REO 022) in a poster presentation at the ASCO Gastrointestinal Cancers Symposium. Of the 18 patients evaluable for response there was one PR and nine had SD. The combined overall PFS of FOLFIRI-naïve and FOLFIRI-failed patients was 7.4 months. The authors concluded that the combination of REOLYSIN and FOLFIRI was safe and well tolerated and resulted in disease control in the majority of evaluable patients, including patients that had previously progressed on Irinotecan.
