DEB-TACE vs cTACE in HCC After TIPS

Summary

This is a Phase 3, open-label, multicenter, randomized controlled clinical trial designed to evaluate the efficacy and safety of Drug-Eluting Bead Transarterial Chemoembolization (DEB-TACE) compared with Conventional Transarterial Chemoembolization (cTACE) in patients with hepatocellular carcinoma (HCC) that is beyond the Milan criteria and who have previously undergone a Transjugular Intrahepatic Portosystemic Shunt (TIPS) procedure. The TIPS procedure is commonly performed to manage complications of portal hypertension, such as variceal bleeding or refractory ascites, in patients with cirrhosis. However, after TIPS, treatment options for HCC-particularly in cases exceeding the Milan criteria-remain limited and not well-defined in current guidelines.

While TACE is a standard locoregional therapy for intermediate-stage HCC, its application in patients with a prior TIPS is controversial due to altered hepatic hemodynamics, which may increase the risk of liver toxicity and compromise treatment safety and efficacy. Preliminary retrospective data suggest that DEB-TACE, which uses calibrated drug-eluting microspheres, may offer a safer and more effective alternative to cTACE in this specific patient population by providing more controlled drug delivery and potentially reducing systemic and hepatic toxicity.

The primary objective of this study is to determine whether DEB-TACE improves Overall Survival (OS) compared to cTACE in patients with beyond-Milan HCC after TIPS. Secondary objectives include comparing the safety profile, Progression-Free Survival (PFS), Objective Response Rate (ORR), Disease Control Rate (DCR), and Quality of Life (QoL) between the two treatment arms.

The study aims to enroll 206 participants who will be randomly assigned in a 1:1 ratio to receive either DEB-TACE or cTACE. The trial will include a 24-month recruitment period and a 24-month treatment and follow-up phase, with a total study duration of 48 months. By directly comparing these two TACE approaches in a prospectively defined and randomized setting, this study seeks to provide high-level evidence to guide the optimal locoregional treatment strategy for HCC patients with a history of TIPS placement.

Interventions

PROCEDURE

DEB-TACE

Experienced interventional radiologists perform transarterial chemoembolization using drug-eluting microspheres (100-300 μm or 300-500 μm) loaded with chemotherapeutic agents (e.g., 70 mg epirubicin or doxorubicin). The procedure involves superselective catheterization of tumor-feeding arteries, with embolization endpoint being angiographic stasis of arterial flow. Repeat treatments are based on 6-8 week imaging, if residual active lesions and preserved liver function are present. Treatment is discontinued upon disease progression, non-operable conditions, or persistent liver impairment.

PROCEDURE

cTACE

Patients receive conventional transarterial chemoembolization using ethiodized oil loaded with chemotherapeutic agents (e.g., 40 mg epirubicin or doxorubicin) followed by gelatin sponge particle embolization if needed. Procedures are performed by experienced interventional radiologists with superselective catheterization. Repeat treatments are based on 6-8 week imaging, provided liver function is preserved. Treatment stops upon disease progression, vascular inoperability, or sustained liver impairment.
