What was measured

The EORTC-QLQ-C30 is a 30-item questionnaire developed to assess the quality of life of cancer patients. Participant responses to the Global Health Status (GHS) question "How would you rate your overall health during the past week?" (Item 29) and the Quality of Life (QoL) question "How would you rate your overall quality of life during the past week?" (Item 30) were scored on a 7-point scale (1=Very Poor to 7=Excellent). Using linear transformation, raw scores were standardized so that scores ranged from 0 to 100, with a higher score indicating a better overall outcome. Per protocol, change from baseline to Week 18 in the GHS/QoL combined score was reported by treatment arm as a pre-specified secondary analysis for all participants.

Analysis population: All randomized participants who received at least one dose of study treatment and completed at least 1 EORTC-QLQ-C30 assessment were analyzed.

Groups in this outcome

Pembrolizumab + SOC

Participants received pembrolizumab 200 mg IV Q3W plus SOC chemotherapy with cisplatin 80 mg/m\^2 IV Q3W and 5-FU 800 mg/m\^2/day continuous IV infusion on Days 1 to 5 (120 hours) Q3W. All treatments were administered on an outpatient basis beginning on Day 1 of each 3-week dosing cycle.

Placebo + SOC

Participants received placebo to pembrolizumab (saline) IV Q3W plus SOC chemotherapy with cisplatin 80 mg/m\^2 IV Q3W and 5-FU 800 mg/m\^2/day continuous IV infusion on Days 1 to 5 (120 hours) Q3W. All treatments were administered on an outpatient basis beginning on Day 1 of each 3-week dosing cycle.
