What This Trial Is Studying

The purpose of the study is to determine if the combination of niraparib with Abiraterone Acetate (AA) plus prednisone compared with AA plus prednisone in participants with deleterious germline or somatic Homologous Recombination Repair (HRR) gene-mutated Metastatic Castration-Sensitive Prostate Cancer (mCSPC) provides superior efficacy in improving radiographic progression-free survival (rPFS). Conditions: Metastatic Castration-sensitive Prostate Cancer Interventions: Niraparib+ Abiraterone acetate fixed dose combination (FDC), Abiraterone acetate (AA), Prednisone, Placebo FDC, Placebo AA Lead Sponsor: Janssen Research & Development, LLC Planned Enrollment: 696 participants
