This is a efficacy and safety study of pembrolizumab (MK-3475, KEYTRUDA®) as monotherapy in participants with previously systemically treated hepatocellular carcinoma (HCC). Study participants may receive pembrolizumab once every 3 weeks for up to 35 administrations (up to approximately 2 years).

The primary objective of this study is to determine the Objective Response Rate (ORR) of pembrolizumab given as monotherapy in participants with previously systemically treated HCC. 

The safety and effectiveness of TheraSphere will be evaluated in patients with unresectable hepatocellular carcinoma in whom treatment with standard-of-care sorafenib is planned. All patients receive the standard-of-care sorafenib with or without the addition of TheraSphere.

The purpose of this study is to determine if tivantinib (ARQ 197) is effective in treating patients with MET diagnostic-high hepatocellular carcinoma (liver cancer) who have already been treated once with another therapy.
