Other interventions - Pembrolizumab
Other interventions - Lenvatinib
Treatment: Drugs - Oxaliplatin
Treatment: Drugs - Capecitabine
Treatment: Drugs - Leucovorin (or Levoleucovorin)
Treatment: Drugs - 5-FU

Experimental: Lenvatinib + Pembrolizumab + Chemotherapy - Participants receive lenvatinib administered orally (PO) every day (QD) in combination with pembrolizumab intravenously (IV) every 6 weeks (Q6W) plus chemotherapy with either capecitabine and oxaliplatin (CAPOX) or chemotherapy with 5-FU, leucovorin, and oxaliplatin (mFOLFOX6). Induction with lenvatinib 8 mg QD plus pembrolizumab (400 mg Q6W) plus chemotherapy (CAPOX or mFOLFOX6) will be administered for 2 cycles (approximately 12 weeks), followed by consolidation with lenvatinib 20 mg QD plus pembrolizumab (400 mg Q6W) for 16 cycles. A cycle is 6 weeks (42 days).

Experimental: Chemotherapy - Participants receive chemotherapy with either CAPOX Q3W or mFOLFOX6 Q2W. A cycle is 6 weeks (42 days).


Other interventions: Pembrolizumab
400 mg Q6W by IV infusion

Other interventions: Lenvatinib
Administered PO QD, 8 mg induction/20 mg consolidation.

Treatment: Drugs: Oxaliplatin
130 mg/m^2 administered by IV infusion on Day 1 of Weeks 1 and 4 of each Q6W cycle as part of CAPOX chemotherapy, or 85 mg/m^2 administered by IV infusion on Day 1 and Week 1, 3 and 5 of each Q6W cycle as part of mFOLFOX6 chemotherapy.

Treatment: Drugs: Capecitabine
1000 mg/m^2 administered PO twice daily (BID) on Days 1-14, 22-35 of each Q6W cycle as part of CAPOX chemotherapy.

Treatment: Drugs: Leucovorin (or Levoleucovorin)
Administered by IV infusion at 400 mg/m^2 (leucovorin) or 200 mg/m^2 (levoleucovorin) on Day 1, and Week 1, 3 and 5 of each Q6W cycle as part of mFOLFOX6 chemotherapy.

Treatment: Drugs: 5-FU
400 mg/m^2 bolus IV infusion followed by 2400 mg/m^2 continuous IV infusion administered on Day 1, and Week 1, 3, 5, of each Q2W cycle as part of mFOLFOX6 chemotherapy.

Summary
Brief 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.
