Summary

Niraparib is an oral inhibitor of poly adenosine diphosphate-ribose polymerase (PARP)-1 and PARP-2. This study will evaluate safety and efficacy of niraparib combined with bevacizumab as maintenance treatment in participants with advanced (stage IIIB-IV) ovarian cancer, fallopian tube cancer, or primary peritoneal cancer following front-line platinum-based chemotherapy with bevacizumab. Eligible participants who achieve complete response (CR), partial response (PR), or no evidence of disease (NED) following treatment with platinum-based chemotherapy in addition to bevacizumab will be enrolled in the study and will receive maintenance treatment with niraparib (for up to 3 years) combined with bevacizumab (for up to 10 months during the maintenance phase or up to a total of 15 months inclusive of the approximately 5 months of bevacizumab received with chemotherapy) or until disease progression, unacceptable toxicity, participant withdrawal, Investigator's decision, or death, whichever comes first. Participants who have not progressed after 3 years of niraparib maintenance treatment may continue with niraparib beyond 3 years if they are benefiting from treatment, upon consultation with Sponsor.

Interventions

DRUG

Niraparib

Niraparib will be administered orally once a day continuously throughout each 21 day cycle (84-day cycle after amendment 2). The starting dose of niraparib will be based on the participant's Baseline actual body weight or platelet count. Participants with a Baseline actual body weight of greater than equal to (\>=) 77 kg and Baseline platelet count of \>=150,000/ microliter (μL) will take 300 mg/day (3X100mg) at each dose administration. Participants with a Baseline actual body weight of less than (\<) 77 kg and/or Baseline platelet count of \<150,000/μL will take 200 mg (2X100 mg) at each dose administration.

BIOLOGICAL

Bevacizumab

Maintenance bevacizumab 15 mg/kg will be administered via a 30-minute IV infusion on Day 1 of every 21-day cycle in the absence of progressive disease (PD), unacceptable toxicity, participant withdrawal, Investigator's decision, or death. Bevacizumab will be administered for up to 10 months during the maintenance phase or up to a total of 15 months inclusive of approximately 5 months of bevacizumab received with chemotherapy.
