What was measured

OS was determined for all participants and was defined as the time from the first dose to death due to any cause. Participants were censored at the last known alive date. The OS was analyzed using the product-limit (Kaplan-Meier) method for censored data. The OS is presented.

Analysis population: All participants who received at least one dose of study treatment during the first course of therapy.

Groups in this outcome

Cohort 1: HCC-Prior Systemic Therapy With Sorafenib

Participants with previously systemically treated HCC received a pembrolizumab 200 mg IV infusion on Day 1 of each 3-week cycle for up to 35 administrations. Participants who stopped pembrolizumab as a result of obtaining a confirmed complete response (CR) or those who stopped after receiving 35 trial treatments were eligible for an additional 17 trial treatments (approximately an additional 1 year of treatment) after progressive disease if they met the criteria for re-treatment.

Cohort 2: HCC-Systemic Therapy Naïve

Participants with HCC who had not received treatment for systemic disease received a pembrolizumab 200 mg IV infusion on Day 1 of each 3-week cycle for up to 35 administrations. Participants who stopped pembrolizumab as a result of obtaining a confirmed complete response (CR) or those who stopped after receiving 35 trial treatments were eligible for an additional 17 trial treatments (approximately an additional 1 year of treatment) after progressive disease if they met the criteria for re-treatment.
