What was measured

FOSI is a validated, 8-item measure of symptom response to treatment for ovarian cancer. Participants responded to their symptom experience over the past 7 days using a 5-point Likert scale scored from "not at all" (0) to "very much" (4). FOSI score was calculated as (sum of item scores)\*8 divided by (number of items answered). The FOSI score ranged from 0 (severely symptomatic) to 32 (asymptomatic). A higher score indicated a better quality of life (QoL). Change from Baseline was calculated by subtracting Baseline value from the post-dose visit value. Baseline was defined as the latest pre-dose assessment (Day 1 pre-dose).

Analysis population: ITT Population. Only those participants with data available at the specified time points were analyzed.

Groups in this outcome

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).

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).
