What was measured

EORTC QLQ-C30 is a questionnaire that rates the overall quality of life in cancer participants. The first 28 questions use a 4-point scale (1=not at all to 4=very much) for evaluating function (physical, role, social, cognitive, emotional), symptoms (diarrhea, fatigue, dyspnea, appetite loss, insomnia, nausea/vomiting, constipation, and pain) and financial difficulties. The last 2 questions use a 7-point scale (1=very poor to 7=excellent) to evaluate overall health and quality of life. Scores were transformed to a range of 0 to 100 using a standard EORTC algorithm. Negative change from baseline values indicated deterioration in health status or functioning and positive changes indicated improvement. Per protocol, data were to be presented for the first course of study treatment.

Analysis population: All participants who received at least 1 dose of study medication and had non-missing assessments at baseline and Week 12. This outcome measure was replaced with a single time-point analysis at Week 18 as pre-specified with Amendment 7 of the protocol (03-Oct-2018).

Groups in this outcome

Pembrolizumab+EP

During each 21-day cycle, participants received pembrolizumab 200 mg intravenously (IV) on Day 1 PLUS etoposide 100 mg/m\^2 IV on Days 1, 2 and 3 PLUS investigator's choice of platinum therapy (carboplatin titrated to an area under the plasma drug concentration-time curve \[AUC\] 5 IV on Day 1 OR cisplatin 75 mg/m\^2 IV on Day 1). Participants who stopped pembrolizumab as a result of obtaining a response of stable disease (SD), partial response (PR), complete response (CR) or those who stopped after receiving pembrolizumab for 24 months for reasons other than disease progression or intolerability, were eligible for up to an additional 1 year of treatment after progressive disease if they met the criteria for retreatment.

Placebo+EP

During each 21-day cycle, participants received placebo (normal saline solution) IV on Day 1 PLUS etoposide 100 mg/m\^2 IV on Days 1, 2 and 3 PLUS investigator's choice of platinum therapy (carboplatin titrated to an AUC 5 IV on Day 1 OR cisplatin 75 mg/m\^2 IV on Day 1).
