For randomized participants who achieved an objective response per modified RECIST, duration of objective response was defined as the time from the date of the first occurrence of a CR or PR (whichever occurred first) until the date that progressive disease or death was documented (whichever occurred first). Participants who had an objective response and did not experience disease progression or death by the time of analysis were censored at the time of the last tumor assessment. Summaries of duration of objective response (median and percentiles) were estimated from Kaplan-Meier curves. 95% CI for duration of objective response was computed using the method of Brookmeyer and Crowley.

Duration of overall survival was defined as the time from randomization to death of any cause. Kaplan-Meier methodology was used. The OS data for participants for whom no death was captured in the clinical database were censored at the last time they were known to be alive. 95% CI was computed using the method of Brookmeyer and Crowley.

The EORTC OV-28 module is a questionnaire that focuses on issues specific to ovarian cancer. It assesses AB/GI symptoms, among others. Participants were asked to indicate the extent to which they experienced AB/GI symptoms in the week prior to assessment. Participants responded on a scale of 1-4 (1=not at all, 2=a little, 3=quite a bit, 4=very much) to the following: Did you have abdominal pain? Did you have a bloated feeling in your abdomen/stomach? Did you have problems with your clothes feeling too tight? Did you experience any change in bowel habit as a result of your disease or treatment? Were you troubled by passing wind/gas/flatulence? Have you felt full too quickly after beginning to eat? Have you had indigestion/heartburn? Data are transformed to a scale from 0 to 100. Lower scores represent better health (fewer symptoms). Participants were considered a responder if they had a 10 point or more reduction in EORTC QLQ-OV28 AB/GI symptom scale score from baseline.

Participants received one of the following chemotherapies at the discretion of the investigator: paclitaxel, 80 mg/m^2 as a 1-hour IV infusion on Days 1, 8, 15, and 22 q4w OR topotecan 4 mg/m^2 as a 30-minute IV infusion on Days 1, 8, and 15 q4w (alternatively, a 1.25 mg/m^2 dose could have been administered over 30 minutes on Days 1-5 q3w) OR PLD 40 mg/m^2 as a 1 mg/min infusion on Day 1 q4w (after Cycle 1 the drug could have been administered as a 1 hour infusion. Depending on chosen chemotherapy, pre-medication was implemented according to local practices. The chosen chemotherapy was combined with bevacizumab 10 milligrams per kilogram (mg/kg) IV every 2 weeks (q2w; or bevacizumab 15 mg/kg q3w if used in combination with topotecan 1.25 mg/m^2 on Days 1-5 on a q3w schedule). The initial bevacizumab infusion was over 90 minutes, with subsequent infusions over 60 minutes and then 30 minutes, as tolerated.
