What was measured

DLTs were assessed during Cycle 1 (21 days) and defined as any of the following, if considered by investigator to be related to any of the study interventions: Grade 4 hematologic toxicities, except neutropenia and febrile neutropenia; Grade 4 neutropenia lasting \>7 days despite appropriate supportive treatment; Grade 4 febrile neutropenia only if the event considered as clinically significant by investigator and sponsor; any Grade 4 non-hematologic toxicity (except laboratory test abnormal including transient electrolyte abnormalities); any Grade 3 non-hematologic toxicity lasting \>72 hours despite appropriate supportive treatment (not laboratory); and any Grade 4 laboratory test value abnormality; any Grade 3 laboratory test value abnormality lasting \>7 days; delay in start of second course of more than 2 weeks (more than 35 days after the first dose) due to toxicity related to study procedures; any Grade 5 toxicity.

Analysis population: All participants who received at least 1 dose of study intervention and who met the criteria for DLT evaluability by finishing Cycle 1 without a DLT or having experienced a DLT

Groups in this outcome

Pembrolizumab + Pemetrexed + Cisplatin

Participants received pembrolizumab 200 mg intravenously (IV) every 3 weeks (Q3W) in combination with pemetrexed 500 mg/m\^2 IV and cisplatin 75 mg/m\^2 IV for 4-6 cycles, followed by pembrolizumab 200 mg/m\^2 IV monotherapy Q3W for up to 35 cycles from the first dose of the study treatment (approximately 2 years). Each cycle was 21 days.
