What was measured

An adverse event was defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and which did not necessarily have to have had a causal relationship with this treatment. An adverse event could therefore be any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that was temporally associated with the use of the Sponsor's product, was also an adverse event. The number of participants who discontinued due to an 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).
