Phase 2

Recruiting

• Conditions: Hepatocellular Carcinoma with PVTT
• Interventions: Procedure: Transjugular intrahepatic portosystemic shunt (TIPS); Drug: Donafenib

• Registration Number: NCT06646198
• Lead Sponsor: Fei Gao

Brief Summary

The purpose of this study is to evaluate the efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) plus half-dose donafenib (a kind of anti-angiogenesis agents) 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 half-dose donafenib (a kind of anti-angiogenesis agents) in advanced hepatocellular carcinoma (BCLC-C Stage) accompanied by tumor thrombosis-associated portal hypertension. Subjects who meet the admission criteria will be treated with half-dose donafenib 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) based on mRECIST. The secondary outcome measures include the duration of response (DOR), disease control rate (DCR), the recurrence rate of portal hypertension-related haemorrhage or ascites, the median progression-free survival time (mPFS) and median overall survival time (mOS). This study also aims to assess the safety and adverse events.
