Summary
Brief summary (as posted)
The purpose of this study is to assess the safety and pharmacokinetics of niraparib when administered in combination with an androgen receptor (AR)-targeted therapy (apalutamide or abiraterone acetate plus prednisone) in adult men with metastatic castration resistant prostate cancer (mCRPC) who may or may not have deoxyribonucleic acid (DNA)-repair anomalies.

- type
- EXPERIMENTAL
- label
- Niraparib + Apalutamide/[Abiraterone Acetate + Prednisone]
- description
- Participants will receive initial starting dose of Niraparib 200 milligram (mg) once daily in combination either with Apalutamide 240 mg (4\*60 mg) once daily or Abiraterone Acetate 1000 mg (4\*250 mg) plus 10 mg Prednisone (5 mg twice daily) for 28 days of cycle 1. Once a safe dose of niraparib is selected with each Andrgen Receptor (AR)-targeted therapy \[Apalutamide or Abiraterone Acetate plus Prednisone\], then an expansion phase (Part 2) will open to further explore safety and assess antitumor activity.
