What this trial studies

This study evaluates the safety, tolerability, and efficacy of combining S-adenosyl-methionine (SAM) with anti-PD-1/PD-L1 antibodies in adult patients with advanced hepatocellular carcinoma (HCC). Participants will receive intravenous treatments of these antibodies alongside SAM, which is known for its role in regulating cancer cell proliferation. The study aims to determine how well this combination works in patients whose cancer cannot be surgically removed. Treatment will continue until disease progression, intolerable toxicity, or withdrawal of consent.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with advanced, unresectable hepatocellular carcinoma and a good performance status.

Not a fit: Patients with active autoimmune diseases or those who do not meet the organ function requirements may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced hepatocellular carcinoma.

How similar studies have performed: Other studies have shown promising results with similar combinations of immunotherapy and supportive treatments, indicating potential for success.
