What was measured

The EORTC QLQ-C30 is a questionnaire to assess the quality of life of cancer patients. Participant responses to "How would you rate your overall health during the past week?" (Item 29) and "How would you rate your overall quality of life during the past week?" (Item 30) are scored on a 7-point scale (1= Very poor to 7=Excellent). Raw scores are standardized with linear transformation so that scores range from 0-100. A higher combined score indicates a better overall health status. Participant post-baseline scores were classified based on change from baseline, "Improved": a ≥10-point improvement in score and confirmed by the next visit; "Stable": a ≥10-point increase or \<10-point change in score OR a \<10-point change in score and a ≥10-point increase in score at the next visit; or "Deteriorated": a ≥10-point deterioration in score when the criteria for improvement/stability weren't met. Participants who didn't meet "Improved", "Stable", or "Deteriorated" criteria reported as "Other".

Analysis population: Per protocol, all randomized participants who received at least one dose of study treatment and completed at least one EORTC QLQ-C30 assessment were analyzed. Participants with no EORTC QLQ-C30 assessment were not included in the analysis.

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.
