Study of Pembrolizumab/Vibostolimab (MK-7684A) in Combination With Concurrent Chemoradiotherapy Followed by Pembrolizumab/Vibostolimab Versus Concurrent Chemoradiotherapy Followed by Durvalumab in Participants With Stage III Non-small Cell Lung Cancer (MK-7684A-006/KEYVIBE-006)

Purpose

This study is to evaluate the safety and efficacy of pembrolizumab/vibostolimab (MK-7684A) in combination with concurrent chemoradiotherapy (cCRT) followed by pembrolizumab/vibostolimab versus cCRT followed by durvalumab in participants with unresectable, locally advanced, stage III Non-small Cell Lung Cancer (NSCLC). The primary hypotheses are that pembrolizumab/vibostolimab with cCRT followed by pembrolizumab/vibostolimab is superior to cCRT followed by durvalumab with respect to the following: - progression free survival (PFS) per Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1 by blinded independent central review (BICR) in participants with programmed cell death ligand 1 (PD-L1) tumor proportion score (TPS) ≥1% and PD-L1 all comer participants. - overall survival (OS) in participants with PD-L1 TPS ≥1% and PD-L1 all comer participants.

pembrolizumab/vibostolimab coformulation+chemotherapy+radiotherapy
For the first 3 cycles, participants receive pembrolizumab/vibostolimab (coformulation of 200 mg pembrolizumab and 200 mg vibostolimab) intravenously (IV) on Day 1 plus 3 cycles of investigator's choice of platinum doublet chemotherapy and concurrent standard thoracic radiotherapy (60 Gray [Gy] in 2 Gy fractions for 30 days total) during Cycles 2, 3. Participants receive pembrolizumab/vibostolimab for Cycles 4-20 or until discontinuation (up to ~14 months). Cycles 1-20 are 21-day cycles. Investigator's choice of chemotherapy: cisplatin 75 mg/m^2 and pemetrexed 500 mg/m^2 on Day 1 of Cycles 1-3 for non-squamous histology only; cisplatin 50 mg/m^2 on Days 1, 8 of Cycles 1-2 and Days 8, 15 of Cycle 3 and etoposide 50 mg/m^2 on Days 1-5 of Cycles 1-2 and Days 8-12 of Cycle 3; carboplatin area under the curve (AUC) 6 mg/ml/min on Day 1 of Cycle 1 and AUC 2 mg/ml/min on Days 1, 8, 15 of Cycles 2-3 and paclitaxel 200 mg/m^2 on Day 1 of Cycle 1 and 45 mg/m^2 on Days 1, 8, 15 of Cycles 2-3.
