简要总结
The purpose of this study is to establish the maximum tolerable dose of niraparib when combined with prostate stereotactic body radiotherapy (SBRT), abiraterone, leuprolide, and prednisone (the phase 1 portion of the study) and determine 3-year biochemical PSA recurrence free-survival with this treatment approach (the phase 2 portion of the study).

结局指标
主要结局
Dose-limiting toxicities (Phase 1)
时间窗: Up to 112 days after initial dose of niraparib
The proportion of patients at each dose level with dose-limiting toxicity (DLT), defined as any treatment related grade 3-5 adverse event experienced within the first 4 treatment cycles (112 days), assessed per NCI's CTCAE version 5.0.
Proportion of patients experiencing biochemical failure
时间窗: Up to 3 years after first dose of niraparib
Change in PSA level from the beginning of study treatment for up to 3 years later will determine the biochemical failure rate. Biochemical failure will be defined using the Phoenix definition of the PSA nadir + 2 ng/mL.
次要结局
- Proportion of patients with undetectable post-treatment PSA(Measured during the end of the 6th cycle of therapy (during week 24 +/- 7 days))
- Prostate cancer specific survival(Up to 5 years after first dose of niraparib)
- Overall survival(Up to 5 years after first dose of niraparib)
- Change in health related quality of life(From baseline up to 3 years after last dose of niraparib)
- Proportion of patients with distant metastases(Up to 5 years after first dose of niraparib)
