The purpose of the study is to demonstrate superiority of Saruparib (AZD5305) relative to placebo added to a standard radiation therapy (RT) + androgen deprivation therapy (ADT) regimen by assessment of metastases-free survival in participants with high-risk and very high-risk localised/locally advanced prostate cancer with a breast cancer gene mutation (BRCAm).
Male participants with a histologically documented diagnosis of prostate adenocarcinoma.
Newly diagnosed high-risk and very high-risk (localised/locally advanced) prostate cancer or a high-risk biochemical recurrence (BCR) following radical prostatectomy.
Provision of a formalin fixed and paraffin embedded (FFPE) tumour tissue sample.
Confirmed BRCA1 or BRCA2 mutation status by central tumour tissue is required for enrolment.
Participants with a history of myelodysplastic syndrome (MDS)/ acute myeloid leukemia (AML) or with features suggestive of MDS/AML.
Participants with any known predisposition to bleeding [e.g., active peptic ulceration, recent (within 6 months) hemorrhagic stroke, proliferative diabetic retinopathy].
Any history of persisting (> 2 weeks) severe cytopenia due to any cause.
Refractory nausea and vomiting, chronic gastrointestinal diseases, inability to swallow the formulated product or previous significant bowel resection that would preclude adequate absorption of saruparib and/or abiraterone.
