Low-dose Bevacizumab Plus Adebrelimab Combined With Transarterial Chemoembolization Followed by TACE-HAIC
brief summary
his is a single-arm, phase II clinical study evaluating the efficacy and safety of low-dose bevacizumab (7.5 mg/kg, Q3W) plus adebrelimab (1200 mg, Q3W) combined with transarterial chemoembolization (TACE) followed by hepatic arterial infusion chemotherapy (HAIC) with the FOLFOX regimen as first-line treatment for patients with unresectable hepatocellular carcinoma (HCC). Eligible participants will receive TACE followed by HAIC (oxaliplatin, leucovorin, and fluorouracil) and subsequent intravenous administration of adebrelimab and low-dose bevacizumab every 3 weeks. The primary endpoint is objective response rate (ORR) assessed by investigators per RECIST v1.1. Secondary endpoints include progression-free survival (PFS), disease control rate (DCR), duration of response (DoR), overall survival (OS), and safety. A total of 38 participants will be enrolled using Simon's two-stage optimal design (alpha=0.05, power=0.8). The study is sponsored by the Third Affiliated Hospital of Sun Yat-sen University. Adebrelimab is provided free of charge for two years by Shanghai Shengdi Pharmaceutical Co., Ltd.
