Researchers are evaluating the effectiveness of Saruparib (AZD5305) compared to placebo when added to a standard radiation therapy (RT) and androgen deprivation therapy (ADT) regimen in men with high-risk and very high-risk localized or locally advanced prostate cancer who have a BRCA gene mutation. This phase III study aims to assess whether Saruparib can improve metastasis-free survival in this population. About 700 adult male participants will be randomly assigned to receive either Saruparib or placebo along with ADT. There are two groups: Cohort A includes 400 participants with newly diagnosed high-risk or very high-risk prostate cancer treated with primary RT or with high-risk biochemical recurrence after radical prostatectomy receiving salvage RT. Cohort B includes 300 participants with very high-risk locally advanced prostate cancer receiving primary RT combined with ADT and abiraterone. Saruparib and placebo will be given orally, and standard ADT and abiraterone with prednisone/prednisolone will be administered as per the regimen. Participants will be followed for up to about 93 months to monitor metastasis-free survival and overall safety. Assessments include imaging scans like CT, MRI, bone scans, and PSMA-PET to confirm disease status. The study also monitors organ function, performance status, and treatment adherence. An independent committee will review safety and efficacy data throughout the trial to ensure participant well-being and study integrity.
