DEB-TACE vs. cTACE as Conversion Therapy for Unresectable Large HCC

Not Applicable

• Conditions: Hepatocellular Carcinoma Non-resectable
• Interventions: Procedure: Drug-eluting bead transarterial chemoembolization (DEB-TACE); Procedure: Conventional transarterial chemoembolization (cTACE)

• Registration Number: NCT04967482
• Lead Sponsor: Second Affiliated Hospital of Guangzhou Medical University

Brief Summary

This study is conducted to evaluate the efficacy of drug-eluting bead transarterial chemoembolization (DEB-TACE) compared with conventional transarterial chemoembolization (cTACE) as the conversion therapy for unresectable large hepatocellular carcinoma (HCC).

Detailed Description

This is a multicenter, prospective and nonrandomized study to evaluate the efficacy of DEB-TACE (with DC Bead) compared with cTACE as the conversion therapy for unresectable large HCC.

At least 216 patients (≥ 108 patients in each arm) with initially unresectable large HCC (\> 7cm) will be enrolled in this study. The patients will receive either DEB-TACE or cTACE as the primary treatment according to their won will. TACE can be repeated on demand based on the evaluation of follow-up laboratory and imaging examination by the multidisciplinary team, and the technique method of each TACE procedure (i.e. DEB-TACE or cTACE) for the same patient should be consistent. During follow-up, the potential resectability of the tumor will be assessed by the multidisciplinary team (MDT). Once the tumors become resectable, curative surgical resection will be recommended for the patients.

The primary end point of this study is success rate of conversion to resection. The secondary endpoints are objective response rate (ORR) of TACE, progression-free survival (PFS), times of TACE procedure to achieve conversion, conversion time, success rate of surgical resection, tumor recurrence rate after resection, tumor-free survival (TFS) of patients who undergo surgical resection, adverse events (AEs) and overall survival (OS).

Arm && Interventions

Group	Intervention	Description
DEB-TACE	Drug-eluting bead transarterial chemoembolization (DEB-TACE)	DEB-TACE will be performed for the patients who choose DEB-TACE as the primary treatment.
cTACE	Conventional transarterial chemoembolization (cTACE)	cTACE will be performed for the patients who choose cTACE as the primary treatment.

Primary Outcome Measures

Name	Time	Method
Success rate of conversion to resection	2 years.	The proportion of patients with initially unresectable large HCC who were evaluated by the surgical team as suitable for second-stage surgical resection after TACE treatment.

Secondary Outcome Measures

Name	Time	Method
Disease-free survival (TFS) of the patients who undergo resection	2 years.	The time between surgical resection and the first tumor recurrence/metastasis or death from any cause, whichever occurs first..
Adverse Events (AEs)	3 years.	Number of patients with AE, treatment-related AE (TRAE), serious adverse event (SAE), assessed by NCI CTCAE v5.0.
Time for successful conversion	2 years.	The duration between the first TACE treatment and the resectability of the tumor. Resectability is assessed by MDT.
Objective response rate (ORR) of TACE treatment	2 years.	The percentage of patients who had a best overall tumor response rating of complete response (CR) or partial response (PR) which is assessed by the investigators according to modified Response Evaluaion Criteria in Solid Tumors (mRECIST).
Progression-free survival (PFS)	3 years.	The time between the first TACE treatment and the first occurrence of disease progression (PD) or death from any cause, whichever occurs first. For the patients who receive surgical resection after TACE, PD is defined as tumor recurrence/metastasis after resection. For the patients who did not undergo surgical resection, PD is assessed by the investigators according to mRECIST.
Times of TACE procedure to achieve conversion	2 years.	The number of TACE procedures performed for the patients when thier tumors become resectable. Resectability of the tumor is assessed by MDT during follow-up.
Overall survival (OS)	3 years.	The time from first TACE until the date of death from any cause.
