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).
