A Prospective, Randomized Study of TACE Combined With Sintilimab, Bevacizumab, and Ipilimumab N01 Treating Advanced HCC

Recruiting now · Phase 2 · Has a placebo group

Conditions studied: Hepatocellular Carcinoma (HCC)

In brief

The goal of this clinical trial is to evaluate the safety, tolerability, and preliminary efficacy of a combination therapy involving TACE, sintilimab, bevacizumab, and ipilimumab N01 for the treatment of advanced hepatocellular carcinoma (HCC). It also aims to explore the potential synergistic mechanisms of this combination. The main questions it aims to answer are: Is the combination of TACE, sintilimab, bevacizumab, and ipilimumab N01 effective and safe for patients with advanced HCC? How do different sequencing schedules of ipilimumab N01 compare in terms of safety and efficacy? What potential biomarkers can predict treatment response? Researchers will compare three different treatment groups: Group A: Receives TACE and a single dose of ipilimumab N01 administered 3 weeks after the first dose of sintilimab and bevacizumab. Group B: Receives TACE and a single dose of ipilimumab N01 administered concurrently with the first dose of sintilimab and bevacizumab. Group C: Receives TACE, sintilimab and bevacizumab (without ipilimumab N01). Participants will: Be screened for eligibility and be randomly assigned to one of the three treatment groups. Receive the assigned study treatment according to their group's schedule. Undergo regular clinic visits for safety checkups, tumor imaging assessments, and response evaluation using RECIST v1.1 and RECICL criteria. Provide biological samples for exploratory biomarker analysis, including: Peripheral blood at baseline and before each treatment cycle (every 3 weeks). Tumor biopsy specimens at baseline and 6 weeks after the first treatment. Surgical specimens if the patient undergoes conversion surgery. Participate in follow-up visits: A safety follow-up visit 30 days after the last study drug dose or before starting new anti-cancer therapy. Subsequent survival follow-up contacts every 90 days to collect information on survival status and any subsequent anti-cancer treatments.
