Groups2
Group 2 names the comparator: placebo.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Niraparib | 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). | 48 | 484 | EG001 |
| Group 2 | Placebo | Participants received placebo matching niraparib 300 milligram (mg) (3×100 mg capsules) (fixed dose) once daily (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 placebo 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 kilogram \[kg\] and Baseline platelet count \>=150,000 per microliter \[μL\]) or 200 mg (2×100 mg capsules for participants with a Baseline body weight \<77 kg or Baseline platelet count \<150,000 per μL). | 31 | 244 | EG000 |
