Phase 3, Randomized Study to Evaluate the Efficacy and Safety of Lenvatinib (E7080/MK-7902) Plus Pembrolizumab (MK-3475) Plus Chemotherapy Compared With Standard of Care Therapy as First-line Intervention in Participants With Advanced/Metastatic Gastroesophageal Adenocarcinoma (LEAP-015)
In Brief
A Phase 3 clinical trial evaluating Pembrolizumab, Lenvatinib, and 4 other interventions for Advanced/Metastatic Gastroesophageal Adenocarcinoma. Completed, enrolled 895 participants across 177 sites in 24 countries.
Detailed Summary
The purpose of this study is to assess the efficacy and safety of lenvatinib (E7080/MK-7902) plus pembrolizumab (MK-3475) plus chemotherapy compared with chemotherapy alone in participants with advanced/metastatic gastroesophageal cancer. The primary study hypotheses are that lenvatinib plus pembrolizumab plus chemotherapy is superior to chemotherapy alone for both overall survival (OS) and progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) as assessed by blinded independent central review (BICR), in participants with programmed cell death-ligand 1 (PD-L1) Combined Positive Score (CPS) ≥1 and in all participants.
