Clinical summary

Summary

The purpose of this study is to assess the efficacy, safety, and pharmacokinetics of niraparib in men with metastatic castration resistant prostate cancer (mCRPC) and deoxyribonucleic acid (DNA) repair anomalies.

Conditions

This trial is treating people with castration resistant prostate cancer

Eligibility

Inclusion

  • Histologically confirmed prostate cancer (mixed histology is acceptable, with the exception of the small cell pure phenotype, which is excluded)
  • Received a taxane-based chemotherapy for the treatment of metastatic prostate cancer with evidence of disease progression on or after treatment, or discontinued from a taxane-based chemotherapy due to an adverse event
  • Received a second-generation or later androgen receptor (AR)-targeted therapy (for example, abiraterone acetate plus prednisone, enzalutamide, apalutamide) for the treatment of metastatic prostate cancer with evidence of disease progression or non-metastatic castration-resistant prostate cancer with evidence of subsequent metastasis
  • Biomarker-positive by at least one of the following criteria: (a) Biallelic deoxyribonucleic acid (DNA)-repair anomaly based on a sponsor validated blood or tissue assay; (b) Germline pathogenic Breast Cancer gene (BRCA) 1 or BRCA2 by any test (somatic local results must be confirmed as positive by the sponsor-validated assay before dosing)
  • Progression of metastatic prostate cancer in the setting of castrate levels of testosterone or history of bilateral orchiectomy at study entry

Exclusion

  • Prior treatment with a poly (adenosine diphosphate [ADP] ribose) polymerase (PARP) inhibitor
  • Prior platinum-based chemotherapy for the treatment of prostate cancer
  • Known history or current diagnosis of myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML)
  • Symptomatic or impending cord compression
  • Symptomatic brain metastases

Inclusion

  • You are able to swallow medication by mouth.
  • 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

  • You have certain types of non-cancer medical conditions.
  • You have had certain treatments, surgical procedures or drugs.
