The primary endpoint for the trial is overall survival (OS); secondary endpoints include progression free survival (PFS), objective response rate (complete response (CR) + partial response (PR)) and duration of response, and safety and tolerability of REOLYSIN when administered in combination with paclitaxel and carboplatin. The first stage of the trial is designed to enroll 80 patients. The second stage is adaptive, and is designed to enroll between 100 and 400 patients with the most probable statistical enrolment being 195 patients in this stage. This adaptive trial design allows frequent data evaluation to determine if the probability of reaching a statistically significant endpoint has been achieved.
The decision to pursue a Phase 3 trial in head and neck cancers was predicated on positive results seen in the Company's U.K. Phase 1 and Phase 2 combination REOLYSIN and paclitaxel/carboplatin clinical trials, as well as significant preclinical work demonstrating synergy in combination with taxane or platinum-based drugs. Updated results from the U.K. Phase 1/2 trial reported in November 2009 demonstrated an overall response rate (PR and CR) of 42% and a total clinical benefit rate (PR + CR + stable disease) of 74%. The Company is currently conducting a confirmatory Phase 2 trial in the U.S. in patients with advanced head and n
