On April 28th, 2023, the FDA approved olaparib plus abiraterone acetate for first line treatment for metastatic castration-resistant prostate cancer, but only in patients whose tumors have BRCA mutations. Although a broad indication for the combination therapy was desired, concerns about the trial design were raised, and the phase III results did not explicitly show that patients without a BRCA mutation would benefit (1).
On August 11th, 2023, the FDA approved the use of niraparib and abiraterone acetate with prednisone in treating patients with BRCA-mutated castration-resistant prostate cancer. The green light comes backed by the robust efficacy data from the MAGNITUDE trial (2).
