What was measured

The CTCAE uses Grades 1 through 5 correlating to AE severity criteria. Grade 1=mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2=moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental Activities of Daily Living (ADL). Grade 3=severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care ADL. Grade 4=life-threatening consequences; urgent intervention indicated. Grade 5=death related to AE. The number of participants who experienced any Grade 3 to 5 AE was reported for each arm according to the treatment received and is presented for the first course of study treatment per protocol.

Analysis population: The analysis population consisted of all participants who received at least 1 dose of study treatment.

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).
