Inclusion criteria

Inclusion criteria: - Male 18 years of age or more - Histologically documented prostate adenocarcinoma which is de novo or recurrent and castration-sensitive. Participants with pathologic features of small cell, neuroendocrine, sarcomatoid, spindle cell, or signet cell histology are not eligible. - Metastatic disease as documented by the investigator prior to randomisation, with clear evidence of 1 bone lesion or more and/or 1 soft tissue lesion or more that is suitable for repeated assessment with CT and/or MRI. - Participant is receiving ADT with a GnRH analogue or has undergone bilateral orchiectomy starting 14 days or more and < 4 months prior to randomisation - ECOG performance status of 0 or 1 with no deterioration over the 2 weeks prior to randomisation. - Provision of FFPE tumour tissue sample and blood sample (for ctDNA) - Confirmed HRRm status by central tumour tissue and/or ctDNA test is required to determine cohort eligibility - Adequate organ and bone marrow function as described in study protocol - Participants must not father children or donate sperm from signing ICF, during the study intervention and for 6 months after the last dose of study intervention. - Participants must use a condom from signing ICF, during study intervention, and for 6 months after the last dose of study drug, with all sexual partners.

MeasureTime frame
Radiographic Progression-Free Survival (rPFS) [ Time Frame: up to approximately 50 months ] rPFS is defined as the time from randomisation to radiographic progression, as assessed by the investigator per RECIST 1.1 (soft tissue) and/or PCWG3 criteria (bone), or, death due to any cause.
