What was measured

An SAE was defined as any untoward medical occurrence that, at any dose: a.) Resulted in death; b.) Was life-threatening; c.) Required inpatient hospitalization or prolongation of existing hospitalization; d.) Resulted in persistent or significant disability/incapacity; e.) Was a congenital anomaly/birth defect; f.) Other important medical events; h.) Was a new cancer (that is not a condition of the study) or i.) Was associated with an overdose. The number of participants who experienced an SAE is presented.

Analysis population: All randomized participants who received at least one dose of study treatment.

Groups in this outcome

Pembrolizumab+Chemotherapy

On Day 1 of each 21-day cycle, participants received an intravenous (IV) infusion of pembrolizumab 200 mg for up to 35 cycles (up to approximately 2 years) PLUS Investigator choice of chemotherapy for up to 6 cycles (paclitaxel 175 mg/m\^2 PLUS cisplatin 50 mg/m\^2 WITH or WITHOUT bevacizumab 15 mg/kg per local label OR paclitaxel 175 mg/m\^2 PLUS carboplatin Area Under the Curve (AUC) 5 for up to 6 cycles, WITH or WITHOUT bevacizumab 15 mg/kg per local label). All treatments were administered until disease progression or toxicity. Eligible participants who stopped the initial course of pembrolizumab with Stable Disease (SD) or better but progressed after discontinuation may have been able to initiate a second course of pembrolizumab for up to 17 cycles (up to approximately 1 additional year) at the investigator's discretion.

Placebo+Chemotherapy

On Day 1 of each 21-day cycle, participants received an IV infusion of placebo (Normal Saline or Dextrose solution) for up to 35 cycles (up to approximately 2 years) PLUS Investigator choice of chemotherapy for up to 6 cycles (paclitaxel 175 mg/m\^2 PLUS cisplatin 50 mg/m\^2 WITH or WITHOUT bevacizumab 15 mg/kg per local label OR paclitaxel 175 mg/m\^2 PLUS carboplatin AUC 5 for up to 6 cycles, WITH or WITHOUT bevacizumab 15 mg/kg per local label). All treatments were administered until disease progression or toxicity.
