| Primary | Progression-Free Survival | 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.

| Secondary | Percentage of Participants With a Best Overall Confirmed Response Based on Combined CA 125 and RECIST Measurements | Response by tumor measurement occurred if there was documented and confirmed complete response (CR) or partial response (PR). For all participants, response was assessed by both the RECIST and by CA 125 levels, according to whether the participant had measurable or non-measurable disease at baseline. Response according to CA 125 levels was defined as at least a 50% reduction from baseline. The decrease had to be confirmed and maintained for at least 28 days. The confirmatory sample must have been less than or equal to the previous sample (within an assay variability of 10%). For overall response, the response categories were "response", "stable disease" and "progressive disease". Stable disease included 1) stable disease as defined by RECIST for solid tumors and 2) CA 125 levels that had not met the definition of "response" or "progressive disease". | All treated patients who received Randomized Treatment (All Treated Population, for Efficacy Analyses) were included in analysis. | Posted | | Number | | percentage of participants | | 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 | | | | ID | Title | Description |
