Comparison of Docetaxel/Prednisone to Docetaxel/Prednisone in Combination With OGX-011 in Men With Prostate Cancer

Summary

This Phase 3 study has been designed to confirm that adding custirsen to standard first-line docetaxel/prednisone treatment can slow tumor progression and enhance survival outcomes compared to standard first-line docetaxel/prednisone treatment alone. This will be a randomized, open-label, multicenter, international trial. Treatment will consist of docetaxel/prednisone/custirsen vs. docetaxel/prednisone. A total of at least 1000 patients will be randomized. Patients will be randomly assigned with equal probability to the two arms.
