The primary hypotheses are that pembrolizumab/vibostolimab (MK-7684A) in combination with chemotherapy is superior to pembrolizumab in combination with chemotherapy with respect to progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as assessed by blinded independent central review (BICR) and with respect to overall survival (OS) in treatment-naïve metastatic participants with non-small cell lung cancer (NSCLC).

Condition Metastatic Non-Small Cell Lung Cancer
Treatment cisplatin, carboplatin, Paclitaxel, Pembrolizumab, Pemetrexed, Nab-paclitaxel, Pembrolizumab/Vibostolimab
