Clinical summary

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.

Conditions

This trial is treating people with castration resistant prostate cancer

Eligibility

Inclusion

  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

  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.

Inclusion

  • You have had a certain type of treatment or surgical procedure.
  • You have had treatment but your cancer has gotten worse or has not responded to the treatment you have been given.
  • Your cancer has spread to other parts of the body (metastatic) or has grown into nearby parts of the body (locally advanced).

Exclusion
