Combining Serplulimab with Bevacizumab Biosimilar and HAIC for Advanced Liver Cancer

Efficacy and Safety of Serplulimab Combined With Bevacizumab Biosimilar and HAIC in Advanced Hepatocellular Carcinoma (HCC) Patients

This study is testing a new combination treatment of Serplulimab, a similar version of Bevacizumab, and chemotherapy directly into the liver to see if it helps people with advanced liver cancer feel better.

What this trial studies

This clinical trial evaluates the efficacy and safety of a combination treatment involving Serplulimab, a biosimilar of Bevacizumab, and Hepatic Arterial Infusion Chemotherapy (HAIC) in patients with advanced Hepatocellular Carcinoma (HCC). Participants must have a confirmed diagnosis of HCC at Barcelona Clinic Liver Cancer (BCLC) Stage C and have not previously received systemic therapies for their condition. The study aims to assess the treatment's effectiveness through measurable intrahepatic lesions over time, following specific assessment criteria.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with advanced Hepatocellular Carcinoma who have not undergone prior systemic therapy.

Not a fit: Patients with advanced HCC who have previously received systemic therapies or have a Child-Pugh score greater than 7 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 liver cancer who have limited treatment alternatives.

How similar studies have performed: While there have been studies exploring similar combination therapies, the specific approach of this trial is novel and has not been extensively tested.
