GroupTitleDescriptionWith the outcomeAnalysedClinicalTrials.gov code
Group 1Niraparib
Participants received niraparib 300 mg (3×100 mg capsules) (fixed dose) QD orally beginning on Day 1 of every cycle (each cycle of 28-days) in a double-blind fashion until a modified starting dose regimen was implemented in protocol amendment. After the protocol amendment, participants received niraparib based upon the participant's Baseline body weight or Baseline platelet count (individualized dose): 300 mg (3×100 mg capsules for participants with a Baseline body weight \>=77 kg and Baseline platelet count \>=150,000 per μL) or 200 mg (2×100 mg capsules for participants with a Baseline body weight \<77 kg or Baseline platelet count \<150,000 per μL).
