About

In this study, investigators aimed to evaluated the efficacy and safety of microwave ablation combined with anlotinib and TQB2450 Solution in patients with advanced hepatocellular carcinoma. Patients were randomly assigned at a one-to-one ratio to receive microwave ablation plus anlotinib and TQB2450 Solution or microwave ablation plus TQB2450 Solution. Primary end points were objective response rate(ORR). Second end points include overall survival, progression-free survival and disease control rate. Safety was assessed in all patients.

80 participants in 2 patient groups

Anlotinib and TQB2450 solution

Experimental group

Description:

Microwave ablation will be performed according to patients' tumor number, size and liver function. Oral anlotinib (12 mg/d) will be administered and its cycle is defined as 2 weeks on-treatment followed by 1 week off-treatment. Patients will be given 1200 mg TQB245 solution intravenously every 3 weeks. The treatment continues until disease progression or treatment intolerance. Anlotinib and TQB2450 solution will be given after 2 weeks of microwave ablation procedure.

Treatment:

Drug: Anlotinib and TQB2450 solution

TQB2450 Solution
