Dendreon Completes Target Enrollment of 500 Patients in Phase 3 IMPACT Study of Provenge(R) For Advanced Prost...(ent options available to them. Webelieve...),Health

The IMPACT study enrolled more than 500 patients at 70 centers in the United States and Canada. Patients with metastatic androgen-independent prostate cancer were eligible for the study. The primary endpoint of the study is overall survival (an event-driven analysis), and time to objective disease progression is a secondary endpoint. The company currently expects an interim analysis for overall survival to be performed in the second half of 2008.

"Considering the limited treatment options available to these critically ill patients, there is a real need for new, safe and effective treatments, particularly those providing a survival benefit."
