Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Treatment: Other - Pembrolizumab
Treatment: Other - 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).


Treatment: Other: Pembrolizumab
400 mg Q6W by IV infusion

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

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.
