Summary

The purpose of this study is to evaluate the efficacy and safety of olaparib versus enzalutamide or abiraterone acetate in subjects with metastatic castration-resistant prostate cancer who have failed prior treatment with a new hormonal agent and have homologous recombination repair gene mutations.

Eligibility Criteria

Inclusion criteria

  • Histologically confirmed diagnosis of prostate cancer.
  • Documented evidence of metastatic castration resistant prostate cancer (mCRPC).
  • 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 .
  • Ongoing therapy with LHRH analog or bilateral orchiectomy.
  • Radiographic progression at study entry while on androgen deprivation therapy (or after bilateral orchiectomy).
  • Qualifying HRR mutation in tumor tissue.

Exclusion criteria

  • Any previous treatment with PARP inhibitor, including olaparib.
  • 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.
  • 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.
  • Subjects with known brain metastases.
