TIPS Plus Half-dose Donafenib in AHCC with PVTT-associated Portal Hypertension

Official title

Transjugular Intrahepatic Portosystemic Shunt (TIPS) Plus Half-dose Donafenib (a Kind of Anti-angiogenesis Agents) in Advanced HCC with Tumor Thrombosis-associated Portal Hypertension: a Prospective, Single-arm, Phase II Study. (DoTH Study)

Overview

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.

Interventions

• Procedure Transjugular intrahepatic portosystemic shunt (TIPS)
  Perform transjugular intrahepatic portosystemic shunt under the guidance of DSA
• Drug Donafenib
  Half-dose donafenib, 100mg BID P.O. unless any evidence of disease progression or unacceptable side effects.

Primary outcome measures

• Objective response rate (ORR) by RECIST 1.1 and mRECIST [Time frame: From date of first dose of study drug until disease progression, stable disease, development of unacceptable toxicity, withdrawal of consent, or sponsor termination (up to 1 year)]

Secondary outcome measures (5)

• Overall survival (OS) [Time frame: From the start date of the TIPS until date of death from any cause, assessed up to 2 years.]
• Progression-free survival (PFS) [Time frame: The progression-free survival (PFS) defined as the time from the date of TIPS to the date of first documented progression (mRECIST or RECIST v1.1) or date of death from any cause, whichever came first, assessed up to 2 years]
• Disease control rate (DCR) [Time frame: From date of first dose of study drug until disease progression, stable disease, development of unacceptable toxicity, withdrawal of consent, or sponsor termination (up to 1 year)]
• Rate of portosystemic shunt stent patency [Time frame: 1, 3, 6, 9, 12 months after TIPS]
• Recurrence rate of portal hypertension-related complications [Time frame: From date of TIPS until portal hypertension-related complications (up to 6 months)]
