PROSPER Trial: Efficacy and Safety Study of Enzalutamide in Patients With Nonmetastatic Castration-Resistant Prostate Cancer

Enzalutamide is an FDA approved androgen receptor antagonist used in the treatment of essentially every phase of advanced prostate cancer, from metastatic hormone-sensitive prostate cancer to metastatic and non-metastatic castration-resistant prostate cancer. Read More

San Francisco, CA (UroToday.com) -- Astellas Pharma Inc. and Pfizer Inc. announced the results of the final overall survival (OS) analysis from the Phase 3 PROSPER trial, which evaluated XTANDI^® (enzalutamide) plus androgen deprivation therapy (ADT) versus placebo plus ADT in men with non-metastatic castration-resistant prostate cancer (nmCRPC).

Men with nonmetastatic, castration-resistant prostate cancer and a rapidly rising prostate-specific antigen (PSA) level are at high risk for metastasis. We hypothesized that enzalutamide, which prolongs overall survival among patients with metastatic, castration-resistant prostate cancer, would delay metastasis in men with nonmetastatic, castration-resistant prostate cancer and a rapidly rising PSA level.
