All trials for HCC - Hepatocellular Carcinoma All trials of EDN combined with TACE/HAIC and Immuno-Targeted Therapy All trials of TACE/HAIC plus Immuno-Targeted Therapy
The goal of this clinical trial is to evaluate the efficacy and safety of combining endovascular denervation (EDN) with transarterial chemoembolization/ hepatic arterial infusion chemotherapy (TACE/HAIC) plus second-line immune-targeted therapy in patients with locally advanced hepatocellular carcinoma (HCC) who have progressed after first-line systemic therapy and present with portal vein tumor thrombus (PVTT).
The main questions this study aims to answer are:
Does the addition of EDN to standard TACE/HAIC and immune-targeted therapy improve intrahepatic progression-free survival (hPFS) based on RECIST 1.1 criteria? What is the safety profile of the combined treatment, including device-related adverse events? Researchers will compare the experimental group (EDN + TACE/HAIC + immune-targeted therapy) with the control group (TACE/HAIC + immune-targeted therapy alone) in a 1:1 randomized design. A total of 62 participants will be enrolled across 8 centers, with an expected enrollment period of 12 months and a 12-month follow-up period.
Participants will:
Undergo screening assessments including imaging (CT/MRI), blood tests, and ECG within specified time windows.
Receive assigned interventions (EDN procedure or control) during the baseline visit (Day 0).
Attend follow-up visits at 1 month (±7 days), 3 months (±14 days), 6 months (±30 days), 9 months (±30 days), and 12 months (±30 days) for repeated imaging, laboratory tests, and safety evaluations.
Have their tumor response, survival outcomes, and adverse events monitored throughout the study.
| Arm | Type | Interventions | Description |
|---|---|---|---|
| Treatment intervention group | Experimental | Combination Product: EDN combined with TACE/HAIC and Immuno-Targeted Therapy | Participants randomized to the treatment intervention group will receive the following combination therapy: 1.A single procedure of Endovascular Denervation (EDN): Percutaneous catheter-based ablation of the peri-arterial sympathetic nerves. 2.On-demand Transarterial Interventional Therapy: This consists of either Transarterial Chemoembolization (TACE) or Hepatic Arterial Infusion Chemotherapy (HAIC), administered based on individual patient's disease assessment and treatment response. 3.Second-line Immuno-Targeted Drug Therapy: Standard systemic therapy with a combination of immune checkpoint inhibitors and targeted agents (e.g., anti-PD-1/PD-L1 antibodies plus tyrosine kinase inhibitors or VEGF inhibitors). The specific drugs are not limited by the protocol and are chosen at the investigator's discretion according to local standards of care. |
| Control group | Active comparator | Combination Product: TACE/HAIC plus Immuno-Targeted Therapy | Participants randomized to the control group will receive the current standard of care for the studied patient population, which consists of: 1. On-demand Transarterial Interventional Therapy: This consists of either Transarterial Chemoembolization (TACE) or Hepatic Arterial Infusion Chemotherapy (HAIC), administered based on individual patient's disease assessment and treatment response. 2. Second-line Immuno-Targeted Drug Therapy: Standard systemic therapy with a combination of immune checkpoint inhibitors and targeted agents (e.g., anti-PD-1/PD-L1 antibodies plus tyrosine kinase inhibitors or VEGF inhibitors). The specific drugs are not limited by the protocol and are chosen at the investigator's discretion according to local standards of care. |
