Brief summary
This study aims to compare the safety and tolerability of cadonilimab applied after curative hepatectomy for hepatocellular carcinoma combined with high - risk recurrent factors.
Detailed description
Hepatectomy and local ablation are the main curative treatment methods for hepatocellular carcinoma, but the 5-year recurrence rate after surgery is as high as 70%, which is the main bottleneck problem affecting the long-term prognosis of patients. This study aims to investigate the safety and tolerability of cadonilimab (PD-1/cytotoxic T lymphocyte antigen-4 (CTLA-4) bispecific antibody) applied after curative hepatectomy for hepatocellular carcinoma combined with high - risk recurrence factors.
Interventions
Patients with hepatocellular carcinoma after curative hepatectomy would receive cadonilimab 10 mg/kg intravenous infusion (dissolved in 0.9% NaCl 250 mL, within 60 minutes) Q3W, until disease progression, death, intolerance to toxicity, withdrawal of informed consent, initiation of new anti-tumor treatment, or termination of treatment for other reasons specified in the protocol. The maximum treatment duration for cadonilimab is 6 months.
