What was measured

An adverse event is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An adverse event can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an adverse event. The number of participants who discontinued study treatment due to an AE is presented. Per protocol, final analysis for this outcome measure was planned to be performed during the first course of therapy only.

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.
