What is being measured
The primary outcome is the main question the study is designed to answer.
Progression-Free Survival (PFS) Per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as Assessed by the Investigator in Participants With Programmed Cell Death-Ligand 1 (PD-L1) Positive Tumors (Combined Positive Score [CPS] ≥1)
PFS was defined as the time from randomization to the first documented progressive disease (PD) per RECIST 1.1 based on Investigator assessment or death due to any cause, whichever occurs first. Per RECIST 1.1, PD was defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. Per protocol, RECIST 1.1 was modified to allow up to 10 target lesions total (up to 5 per organ). The appearance of one or more lesions and the unequivocal progression of non-target lesions was also considered PD. Per protocol, PFS per RECIST 1.1 as assessed by the Investigator in participants with PD-L1 CPS ≥1 is reported here. PFS was calculated using the product-limit (Kaplan-Meier) method for censored data.
Measured: Up to ~38 months
PFS Per RECIST 1.1 as Assessed by the Investigator in All Participants
PFS was defined as the time from randomization to the first documented progressive disease (PD) per RECIST 1.1 based on Investigator assessment or death due to any cause, whichever occurs first. Per RECIST 1.1, PD was defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. Per protocol, RECIST 1.1 was modified to allow up to 10 target lesions total (up to 5 per organ). The appearance of one or more lesions and the unequivocal progression of non-target lesions was also considered PD. PFS per RECIST 1.1 as assessed by the Investigator will be reported for all participants. PFS was calculated using the product-limit (Kaplan-Meier) method for censored data.
Measured: Up to ~38 months

PFS Per RECIST 1.1 by Blinded Independent Central Review (BICR) in Participants With PD-L1 CPS ≥1
PFS is defined as the time from randomization to the first documented disease progression per RECIST 1.1 based on blinded independent central review assessment or death due to any cause, whichever occurs first. Per RECIST 1.1, PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. The appearance of one or more lesions and the unequivocal progression of non-target lesions is also considered PD. The PFS per RECIST 1.1 as assessed by blinded independent central review (BICR) in participants with PD-L1 CPS ≥1 is reported here.

Change From Baseline in Global Health Status/Quality of Life (GHS/Qol) Score (Items 29 and 30) Using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30)
The EORTC QLQ-C30 is a questionnaire to assess the overall quality of life of cancer patients. Participant responses to the questions "How would you rate your overall health during the past week?" and "How would you rate your overall quality of life during the past week?" are scored on a 7-point scale (1= Very poor to 7=Excellent). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. A higher score indicates a better overall health status. The change from baseline in EORTC QLQ-C30 Items 29 and 30 combined score will be presented.
Measured: Baseline and up to ~64 months
Time to Deterioration (TTD) in the GHS/Qol Score (Items 29 and 30) Using the EORTC QLQ-C30
TTD is defined as the time from Baseline to the first onset of a ≥10-point negative change (decrease) from Baseline in GHS (EORTC QLQ-C30 Items 29 and 30) score. Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. The TTD, as assessed based on a ≥10-point negative change (decrease) from Baseline in GHS score, will be presented. A longer TTD indicates a better outcome.
Measured: Up to ~64 months
Change From Baseline in the Abdominal and Gastrointestinal (GI) Symptoms Score (Items 31 to 36) Using the EORTC Quality of Life Questionnaire-Ovarian Cancer (QLQ-OV28) Abdominal/GI Symptom Scale
The EORTC QLQ-OV28 is an abdominal and gastrointestinal questionnaire (items 31-36). Participant responses to the question "Did you have abdominal pain ?" are scored on a 4-point scale (1=Not at All to 4=Very Much). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. The change from baseline in abdominal and gastrointestinal symptoms (EORTC QLQ-LC28 Items 31-36) score will be presented. A lower score indicates a better outcome.
Measured: Baseline and up to ~64 months
TTD in the Abdominal and GI Symptoms Score (Items 31 to 36) Using the EORTC QLQ-OV28 Abdominal/GI Symptom Scale
TTD is defined as the time from Baseline to the first onset of a ≥10-point negative change (decrease) from Baseline in GHS (EORTC QLQ-C28 Items 31-36) score. Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. The TTD, as assessed based on a ≥10-point negative change (decrease) from Baseline in GHS score, will be presented. A longer TTD indicates a better outcome.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The primary objective is to compare pembrolizumab plus paclitaxel with or without bevacizumab to placebo plus paclitaxel with or without bevacizumab, with respect to progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as assessed by the investigator. The hypotheses are that pembrolizumab plus paclitaxel with or without bevacizumab is superior to placebo plus paclitaxel with or without bevacizumab, with respect to PFS per RECIST 1.1 as assessed by the investigator for participants with programmed cell death ligand 1 (PD-L1) positive tumors (Combined Positive Score [CPS] ≥1) and that pembrolizumab plus paclitaxel with or without bevacizumab is superior to placebo plus paclitaxel with or without bevacizumab, with respect to PFS per RECIST 1.1 as assessed by the investigator for all participants.

Primary outcome
Progression-Free Survival (PFS) Per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as Assessed by the Investigator in Participants With Programmed Cell Death-Ligand 1 (PD-L1) Positive Tumors (Combined Positive Score [CPS] ≥1)
Time frame: Up to ~38 months
PFS was defined as the time from randomization to the first documented progressive disease (PD) per RECIST 1.1 based on Investigator assessment or death due to any cause, whichever occurs first. Per RECIST 1.1, PD was defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. Per protocol, RECIST 1.1 was modified to allow up to 10 target lesions total (up to 5 per organ). The appearance of one or more lesions and the unequivocal progression of non-target lesions was also considered PD. Per protocol, PFS per RECIST 1.1 as assessed by the Investigator in participants with PD-L1 CPS ≥1 is reported here. PFS was calculated using the product-limit (Kaplan-Meier) method for censored data.
