Study Summary

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).

Primary Outcome

MFS is defined as the time from randomisation until the date of first appearance of distant metastases, confirmed by standard clinical imaging \[computed tomography (CT)/ magnetic resonance imaging (MRI) and bone scan, or prostate-specific membrane antigen-positron emission tomography (PSMA-PET)\], as assessed by blinded independent central review (BICR) or death due to any cause.
