Since 2018, apalutamide, darolutamide, and enzalutamide have been approved for the treatment of men with non-metastatic castration-resistant prostate cancer (M0CRPC). These approvals were based on the results of three separate randomized, placebo-controlled, phase III trials: SPARTAN (apalutamide), ARAMIS (darolutamide) and PROSPER (enzalutamide). These trials included men with M0CRPC and a short PSA doubling time (≤10 months). Results demonstrated a longer metastasis-free survival with these agents when used in conjunction with androgen deprivation therapy (ADT), compared to ADT alone. Updated results of these trials presented in the 2020 annual meeting of American Society of Oncology (ASCO) showed significantly improved overall survival with these agents. Based on these results, apalutamide, darolutamide, and enzalutamide can now be considered the standard of care treatment options for the treatment of men with M0CRPC.
