Study Arms:
- Cohort A (Type: EXPERIMENTAL): Participants received 1 cycle of carboplatin area under the curve (AUC) 6 mg/mL/min with paclitaxel 200 mg/m\^2 and pembrolizumab 200 mg on Day 1. Approximately 3 weeks later, participants received carboplatin AUC 2 mg/mL/min with paclitaxel 45 mg/ m\^2 administered weekly for 6 weeks along with 2 cycles of pembrolizumab 200 mg administered every 3 weeks (Q3W) in conjunction with standard thoracic radiotherapy (TRT) (60 Gray \[Gy\] in 2 Gy fractions administered 5 days per week for 6 weeks). Participants then received 14 additional cycles of pembrolizumab 200 mg administered Q3W. 1 cycle=21 days.
- Cohort B (Type: EXPERIMENTAL): Participants received 3 cycles of cisplatin 75 mg/m\^2 with pemetrexed 500 mg/m\^2 and pembrolizumab 200 mg on Day 1 of each cycle. Treatment was given in conjunction with standard TRT (60 Gy in 2 Gy fractions administered 5 days per week for 6 weeks) in cycles 2 and 3. Participants then received 14 additional cycles of pembrolizumab 200 mg administered Q3W. 1 cycle=21 days.
