Phase III

A Phase 3 Multicenter, Randomized, Double-blinded, Active-controlled, Clinical Study to Evaluate the Safety and Efficacy of Lenvatinib (E7080/MK-7902) With Pembrolizumab (MK-3475) in Combination With Transarterial Chemoembolization (TACE) Versus TACE in Participants With Incurable/Non-metastatic Hepatocellular Carcinoma (LEAP-012)

  • Study HIC#:2000026970
  • Last Updated:07/15/2021

The purpose of this study is to evaluate the efficacy and safety of lenvatinib and pembrolizumab in combination with TACE versus TACE plus oral and intravenous (IV) placebos in participants with incurable, non-metastatic hepatocellular carcinoma (HCC). The primary hypotheses are that pembrolizumab plus lenvatinib in combination with TACE is superior to placebo plus TACE with respect to progression-free survival (PFS) and overall survival (OS).

Trial Purpose and Description

Primary Outcome Measures  :

  1. Progression-free Survival (PFS) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) [ Time Frame: Up to ~5 years ]PFS is defined as the time from randomization to the first documented progressive disease or death due to any cause, whichever occurs first. Responses are according to RECIST 1.1 as assessed by blinded independent central review (BICR).
  2. Overall Survival (OS) [ Time Frame: Up to ~5 years ]OS is defined as the time from randomization to death due to any cause.
