Efficacy and Safety Study of Pembrolizumab (MK-3475) With or Without Lenvatinib (MK-7902/E7080) in Adults With Programmed Cell Death-Ligand 1 (PD-L1)-Positive Treatment-naïve Nonsmall Cell Lung Cancer (NSCLC) [MK-7902-007/E7080-G000-314/LEAP-007] - China Extension Study (LEAP-007)

A Phase 3, Randomized, Double-blind Trial of Pembrolizumab (MK-3475) With or Without Lenvatinib (E7080/MK-7902) in Participants With Treatment-naïve, Metastatic Nonsmall Cell Lung Cancer (NSCLC) Whose Tumors Have a Tumor Proportion Score (TPS) Greater Than or Equal to 1% (LEAP-007)

The purpose of this study is to assess the safety and efficacy of pembrolizumab (MK-3475) combined with lenvatinib (MK-7902/E7080) compared to pembrolizumab alone (with placebo for lenvatinib) in treatment-naïve adults with no prior systemic therapy for their metastatic non-small cell lung cancer (NSCLC) whose tumors have a programmed cell death-ligand 1 (PD-L1) Tumor Proportion Score (TPS) greater than or equal to 1%.

The primary study hypotheses are that: 1) the combination of pembrolizumab and lenvatinib is superior to pembrolizumab alone as assessed by Progression-free Survival (PFS) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1); and 2) the combination of pembrolizumab and lenvatinib is superior to pembrolizumab alone as assessed by Overall Survival (OS).
