A Phase 2 Efficacy and Safety Study of Niraparib in Men With Metastatic Castration-Resistant Prostate Cancer and DNA-Repair Anomalies
Brief SummaryThe 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.
Detailed DescriptionThis is a multicenter and open-label (participants and researchers are aware of the treatment that participants are receiving) study that consists of 4 phases; a Prescreening Phase for biomarker evaluation only, a Screening Phase, a Treatment Phase (Cycle 1 Day 1 and will continue until the study drug is discontinued), and a Follow-up Phase (every 3 months after end of treatment visit). Participants will be monitored for safety during the study period, and up to 30 days after the last dose of study drug.
Inclusion and Exclusion Criteria
- Histologically confirmed prostate cancer (mixed histology is acceptable, with the exception of the small cell pure phenotype, which is be 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 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
- Biomarker-positive for deoxyribonucleic acid (DNA)-repair anomalies
- Progression of metastatic prostate cancer in the setting of castrate levels of testosterone or history of bilateral orchiectomy at study entry
- 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
