Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryProgression-free Survival (PFS) as Assessed by Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1From randomization until PD or death, whichever occurred first (up to approximately 36 months)
PFS was defined as the time from randomization until progressive disease (PD) or death whichever occurred first. PD: At least a 20% increase in the sum of the longest diameters (SoD) of target lesion, taken as reference the smallest (nadir) SoD since and including baseline. In addition to the relative increase of 20%, the SoD must also demonstrate an absolute increase of at least 5 millimeters (mm). Unequivocal progression of non-target lesions and appearance of new lesions. Unequivocal progression should not normally trump target lesion status. It must be representative of overall disease status change, not a single lesion increase.
SecondaryObjective Response Rate (ORR), as Assessed by the Investigator Using RECIST v1.1Up to approximately 36 months
ORR was defined as percentage of participants with a confirmed best overall response (BOR) of complete response (CR) or partial response (PR). CR: Disappearance of all target or non-target lesions. All pathological or non-pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. PR: At least 30% decrease in the sum of the longest diameters (SoD) of target lesions, taking as reference the baseline SoD.
SecondaryOverall Survival Assessed by the Investigator Using RECIST v1.1Up to approximately 45 monthsOverall survival was defined as the time from the date of first dose until the date of death from any cause, estimated using the Kaplan-Meier method.
Secondary
Number of Participants Achieving at Least 15 Point Absolute Improvement in the Abdominal/Gastrointestinal (GI) Scale of European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire - Ovarian Cancer Module 28 (QLQ-OV28)
Baseline and Week 8 or 9
The EORTC QLQ-OV28 is specific for ovarian cancer and consists of 28 items assessing abdominal/gastrointestinal symptoms (6 items), peripheral neuropathy (2 items), other chemotherapy side effects (5 items), hormonal symptoms (2 items), body image (2 items), attitudes to disease/treatment (3 items), sexuality (4 items) and 4 other single items. Each scale was scored from 0 to 100 with higher scores on the symptom scales indicating greater symptom burden. Higher scores represent a higher ("better") level of functioning. Presented here are the number of participants achieving at least 15 point absolute improvement at Week 8 or Week 9 in the abdominal/GI scale of the EORTC QLQ-OV28.
SecondaryNumber of Participants With Treatment-emergent Adverse Events (TEAEs)Up to approximately 37 months
An adverse event (AE) was defined as any untoward medical occurrence that developed or worsened in severity during the conduct of a clinical study and did not necessarily have a causal relationship to study drug. TEAEs were defined as AEs with an onset date on or after the first dose of study drug, and within 30 days of the last dose of study drug or prior to the start of a new anticancer treatment, whichever occurred first. A summary of serious and all other non-serious adverse events regardless of causality is located in the Reported Adverse Events module.
SecondaryDuration of Response (DOR) as Assessed by the Investigator Using RECIST v1.1Up to approximately 34 months
DOR was defined as the time from the date of the first response (CR or PR), until the date of PD or death from any cause, whichever occurred first. DOR for participants who have not progressed or died at the time of analysis are censored at the date of their last tumor assessment. PD: At least a 20% increase in the SoD of target lesion, taken as reference the smallest (nadir) SoD since and including baseline. In addition to the relative increase of 20%, the SoD must also have demonstrated an absolute increase of at least 5 mm. DOR was estimated using the Kaplan-Meier method.
SecondaryPercentage of Participants With Cancer Antigen 125 (CA-125) Confirmed Clinical Response Per Gynecologic Cancer Intergroup (GCIG) CriteriaBaseline up to approximately 36 monthsThe GCIG CA-125 response was defined as at least 50% reduction in CA-125 levels from baseline. The response must have been confirmed and maintained for at least 28 days.
SecondaryTime to Second Progression-Free Survival (PFS 2)Up to approximately 44 monthsPFS 2 was defined as the time from date of randomization until second disease progression or death whichever occurred first.
