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 compared between all participants of the pembro mono arm and the SOC arm as a pre-specified secondary analysis. As specified by the protocol, change from baseline to Week 18 in the GHS/QoL combined score was compared separately between all participants of the pembro combo arm and SOC arm and is presented later in the record.
Analysis population: Participants in the pembro mono arm and SOC arm who received ≥1 dose of study drug and who had EORTC-QLQ-C30 assessments available at baseline or post-baseline up to Week 18. Per protocol, the pembro combo arm was compared to the SOC arm separately and not included in this analysis.
Groups in this outcome
Pembrolizumab Monotherapy (Pembro Mono)
Participants received pembrolizumab 200 mg IV Q3W.
Pembrolizumab + SOC Chemotherapy (Pembro Combo)
Participants received pembrolizumab 200 mg Q3W plus cisplatin 80 mg/m\^2 Q3W plus 5-FU 800 mg/m\^2/day IV infusion on Days 1-5 Q3W. Capecitabine 1000 mg/m\^2 twice a day (BID) on Days 1-14 Q3W could be substituted for 5-FU per local guidelines.
Placebo + SOC Chemotherapy (SOC)
Participants received placebo IV Q3W plus cisplatin 80 mg/m\^2 Q3W plus 5-FU 800 mg/m\^2/day IV infusion on Days 1-5 Q3W. Capecitabine 1000 mg/m\^2 BID on Days 1-14 Q3W could be substituted for 5-FU per local guidelines.
