Astellas Pharma Inc. and Pfizer Inc. announced that the phase III ARCHES trial evaluating XTANDI (enzalutamide) plus androgen deprivation therapy (ADT) in men with metastatic hormone-sensitive prostate cancer (mHSPC) met its primary endpoint, significantly improving radiographic progression-free survival (rPFS) versus ADT alone. The preliminary safety analysis of the ARCHES trial appears consistent with the safety profile of XTANDI in previous clinical trials in castration-resistant prostate cancer (CRPC). Detailed results will be submitted for presentation at an upcoming medical congress.
