Description
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.
Official Title
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)
Details
There will be 2 parts to the study: a Safety Run-in (Part 1) and the Main Study (Part 2). In Part 1 (Safety Run-in), approximately 12 participants will be treated with lenvatinib in combination with pembrolizumab and chemotherapy with either capecitabine and oxaliplatin (CAPOX), or 5-fluorouracil (5-FU), Leucovorin, and oxaliplatin (mFOLFOX6). Participants will be closely followed for dose-limiting toxicities for 21 days after the first dose of study intervention.
In Part 2, up to 878 eligible participants (not including those participating in Part 1) will be randomly assigned in a 1:1 ratio to either lenvatinib plus pembrolizumab plus chemotherapy (CAPOX or mFOLFOX6) or Chemotherapy alone (CAPOX or mFOLFOX6).
Participants can receive up to 18 infusions (up to 2 years) of pembrolizumab in the first course. Participants may be eligible to receive a second course of pembrolizumab (approximately 1 year) at the investigator's discretion.
