Show eligibility criteria text
Inclusion criteria 1. Histologically confirmed diagnosis of prostate cancer. 2. Documented evidence of metastatic castration resistant prostate cancer (mCRPC). 3. Subjects must have progressed on prior new hormonal agent (e.g. abiraterone acetate and/or enzalutamide) for the treatment of metastatic prostate cancer and/or CRPC . 4. Ongoing therapy with LHRH analog or bilateral orchiectomy. 5. Radiographic progression at study entry while on androgen deprivation therapy (or after bilateral orchiectomy). 6. Qualifying HRR mutation in tumor tissue. Exclusion criteria 1. Any previous treatment with PARP inhibitor, including olaparib. 2. Subjects who have any previous treatment with DNA-damaging cytotoxic chemotherapy, except if for non-prostate cancer indication and last dose \> 5 years prior to randomization. 3. Other malignancy (including MDS and MGUS) within the last 5 years except: adequately treated non-melanoma skin cancer or other solid tumors curatively treated with no evidence of disease for ≥5 years. 4. Subjects with known brain metastases.
