Description of intervention(s) / exposure
Treatment: Drugs - Pembrolizumab 200 mg
Treatment: Drugs - Paclitaxel 45 mg/m^2
Treatment: Drugs - Carboplatin AUC6
Treatment: Drugs - Cisplatin 75 mg/m^2
Treatment: Drugs - Pemetrexed 500 mg/m^2
Treatment: Other - Thoracic Radiation Therapy (TRT)
Treatment: Drugs - Paclitaxel 200 mg/m^2
Treatment: Drugs - Carboplatin AUC2

Experimental: Cohort A - 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.

Experimental: Cohort B - 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.

Summary
Brief summary
This is a trial in adult participants with unresectable, locally advanced, Stage III
non-small cell lung cancer (NSCLC) treated with pembrolizumab in combination with platinum
doublet chemotherapy and standard thoracic radiotherapy followed by pembrolizumab
monotherapy. The primary hypothesis of the trial is that within each platinum doublet
chemotherapy cohort, the percentage of participants who develop Grade 3 or higher pneumonitis
is =10% and objective response rate (ORR) by blinded independent central review (BICR).
