Participants who did not progress or died while being followed were censored at the time of the last valid tumor assessment or valid CA 125 assessment. |
| Progression-Free Survival | Screening and Day 15 of Cycles 2, 4, 6, and Day 15 of all cycles from Cycle 7 to 17 until disease progression up to 104 weeks | Progression-free survival was defined as the time from first administration of study drug (Study Day 1) to documented disease progression or death, whichever occurred earlier. Disease progression was assessed according to RECIST, for participants with measurable disease, or by changes in CA 125 according to GCIG for all participants.
