This is a study of combination anti-PD-1/PD-L1 antibodies and S-adenosyl-methionine (SAM) for adult patients (≥18) with advanced hepatocellular carcinoma.~SAM is a compound found naturally in the body and is available as a dietary supplement in the U.S. SAM is a prescription drug in China treating liver disease and advanced HCC with poor liver function under certain circumstances. Also, SAM has recently been shown to play a key role regulating cancer cell proliferation trough epigenetic pathway.~Anti-PD-1/PD-L1 antibodies (including pembrolizumab, nivolumab, sintilimab, toripalimab, camrelizumab, tislelizumab and atezolizumab etc.) are given intravenously at assigned dose. Treatment may continue until disease progression, intolerable toxicity, or consent withdrawal.~This study is aimed to evaluate the safety and efficacy of the combination of SAM and PD-1/PD-L1 monoclonal antibody in unresectable late-stage HCC patients.
This study is being done to analyze the safety, tolerability, and efficacy of treatment using combination of SAM and anti-PD-1/PDL1 antibodies for patients with advanced hepatocellular carcinoma.
