Brief Summary

The purpose of this study is to evaluate the efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) plus Cadonilimab (a PD-1/CTLA-4 bispecific antibody) in advanced hepatocellular carcinoma (BCLC-C Stage) accompanied by tumor thrombosis-associated portal hypertension.

Detailed Description

This is a prospective, single-arm, phase II study to evaluate the efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) plus Cadonilimab (a PD-1/CTLA-4 bispecific antibody) in advanced hepatocellular carcinoma (BCLC-C Stage) accompanied by tumor thrombosis-associated portal hypertension. Subjects who meet the admission criteria will be treated with Cadonilimab after TIPS until disease progression, intolerable toxicity, death, withdrawal of the patient, or the researchers determined that the drug must be discontinued.

The primary outcome measure is to evaluate the objective response rate (ORR). The secondary outcome measures include the duration of response (DOR), disease control rate (DCR), overall survival rate (OSR) in 6- and 12-months, the median progression-free survival time (mPFS) and median overall survival time (mOS). This study also aims to assess the safety and adverse events.
