Phase 3
Active, not recruiting
Conditions
Carcinoma, Hepatocellular
Interventions
Drug: Oral Placebo
Drug: IV Placebo
Procedure: TACE
Registration Number
NCT04246177
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

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).

Primary Outcome Measures

Progression-free Survival (PFS) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1)Up to ~43 months

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).

Overall Survival (OS)Up to ~95 months

OS is defined as the time from randomization to death due to any cause.

ORR is defined as the percentage of participants who have a confirmed complete response (CR: disappearance of all target lesions) or partial response (PR: at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters).

Responses are according to mRECIST as assessed by BICR.

Duration of Response (DOR) per mRECISTUp to ~95 months

DOR is determined by disease assessment and is defined as the time from the first documented evidence of a response of CR (disappearance of any intratumoral arterial enhancement in all target lesions) or PR (at least a 30% decrease in the sum of diameters of viable \[enhancement in the arterial phase\] target lesions, taking as reference the baseline sum of the diameters of target lesions) until the first documented disease progression or death due to any cause, whichever occurs first. Responses are according to mRECIST as assessed by BICR.

Percentage of Participants Who Experience At Least One Adverse Event (AE)Up to ~95 months

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The percentage of participants who experience at least one AE will be reported.

Percentage of Participants Who Discontinue Study Drug Due to an AEUp to ~95 months

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The percentage of participants who discontinue study drug due to an AE will be reported.

Objective Response Rate (ORR) per mRECISTUp to ~95 months

ORR is defined as the percentage of participants who have a confirmed complete response (CR: disappearance of any intratumoral arterial enhancement in all target lesions) or partial response (PR: at least a 30% decrease in the sum of diameters of viable \[enhancement in the arterial phase\] target lesions, taking as reference the baseline sum of the diameters of target lesions).
