Clinical Trial Summary

This study will evaluate the safety and efficacy of pembrolizumab (MK-3475) versus placebo as adjuvant therapy in participants with hepatocellular carcinoma (HCC) and complete radiological response after surgical resection or local ablation. The primary hypotheses of this study are that adjuvant pembrolizumab is superior to placebo with respect to: 1) recurrence-free survival (RFS) as assessed by blinded independent central review (BICR); and 2) overall survival (OS).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Recurrence-Free Survival (RFS)	RFS is defined as the time from randomization to first documentation of disease recurrence (local, regional, or distant) as assessed by BICR or by pathology consistent with HCC if required per the site's standard of care, or death due to any cause (both cancer and non-cancer causes of death), whichever occurs first.	Up to ~6 years
Primary	Overall Survival (OS)	OS is defined as the time from randomization to death due to any cause.	Up to ~8 years
Secondary	Percentage of Participants who Experience an Adverse Event (AE)	An AE is defined as any unfavorable and unintended sign, symptom, or disease (new or worsening) temporally associated with the use of study therapy, regardless of whether or not a causal relationship with the study therapy can be determined.	Up to ~8 years
