About

Transcatheter arterial chemoembolization (TACE) + sorafenib therapy has been demonstrated to exert a beneficial effective on time-to-tumor-progression (TTP) in patients with unresectable hepatocellular carcinoma (HCC) in some studies. However, the beneficial effect varies among studies conducted in different areas of the world. The objectives of this study are (1) to understand whether GALNT14 TT genotype patients respond better than do GALNT14 non-TT genotype patients when treated by TACE; and (2) to understand whether GALNT14 non-TT genotype patients can benefit from TACE plus sorafenib (Nexavar) combination therapy. Patients enrolled will be stratified by GALNT14 genotyping. The GALNT14 "non-TT" patients were then randomized into two subgroups to evaluate the safety, tolerability and efficacy of TACE plus sorafenib therapy.

The primary endpoint of this study is the efficacy of TACE with or without sorafenib combination therapy evaluated by complete remission (CR).

The secondary endpoints are:

1. Time to partial or complete response (PR + CR).
2. Time-to-tumor-progression (TTP) and the progression free survival (PFS).
3. Overall survival (OS).
4. Safety and tolerability of TACE plus sorafenib therapy.

Full description

The strategy of TACE + sorafenib is now being intensively investigated. It is a safe approach with significant beneficial effect on TTP in some studies, but the beneficial effect on OS remains uncertain. In the present study, we hypothesized that the GALNT14 genotype might play a role in this issue. Our pilot study indicated that GALNT14 "TT" genotype was associated with a favorable complete response rate in patients treated by TACE alone. This genotype was present in ~ 25% of Chinese population coming from Taiwan, Colorado (US), or Beijing (China), and in ~ 7% of Italian population. But it was present in ~ 50% of Japanese population. The lower percentage of a TACE - favorable genotype in Chinese and Italian population could explain the different results between Japanese and Chinese/Italian clinical trials. It is possible that in a population with higher percentage of TACE - favorable genotype (GALNT14 "TT"), the beneficial effect of sorafenib adjuvant treatment might not be detected. In this study, we proposed to examine the TACE + sorafenib effect in patients with GALNT14 "non-TT" genotype, a TACE - unfavorable genotype.

Inclusion criteria

1. Confirmed Diagnosis of HCC:

   Cirrhotic subjects: Clinical diagnosis by AASLD criteria HCC can be defined in cirrhotic subjects by one imaging technique (CT scan, MRI, or second generation contrast ultrasound) showing a nodule larger than 2cm with contrast uptake in the arterial phase and washout in venous or late phases, or two imaging techniques showing this radiological behaviour for nodules of 1-2cm in diameter Cytohistological confirmation is required for subjects who do not fulfill these eligibility criteria

   Non-cirrhotic subjects:

   For subjects without cirrhosis, histological confirmation is mandatory Documentation of original biopsy for diagnosis is acceptable

2. Never received TACE/ chemotherapy/ radiotherapy or targeted agents prior to this study.

3. Patients should be either in BCLC clinical stage B (multinodular asymptomatic tumors without extra-hepatic spread or portal vein invasion) with or without unilateral secondary or tertiary branches of portal vein invasion. Main portal vein invasion or extra-hepatic spread is not allowed.

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: None (Open label)

200 participants in 3 patient groups

GALNT14 TT

Active Comparator group

Description:

Patients will be treated by Transcatheter arterial chemoembolization every 12 ± 2 weeks dependent on CT evaluation. Before each TACE, dynamic CT will be performed for pre-treatment evaluation. When no viable tumor is seen on CT, TACE is to be discontinued.

Treatment:

Procedure: TACE

GALNT14 non-TT TACE alone

Active Comparator group

Description:

Patients will be treated by Transcatheter arterial chemoembolization every 12 ± 2 weeks dependent on CT evaluation. Before each TACE, dynamic CT will be performed for pre-treatment evaluation. When no viable tumor is seen on CT, TACE is to be discontinued.

Treatment:

Procedure: TACE

GALNT14 non-TT TACE plus sorafenib

Experimental group

Description:

Patients will be treated by Transcatheter arterial chemoembolization every 12 ± 2 weeks dependent on CT evaluation, plus sorafenib adjuvant therapy. Before each TACE, dynamic CT will be performed for pre-treatment evaluation. When no viable tumor is seen on CT, TACE is to be discontinued. patients will receive sorafenib 400 mg/d between each TACE. Patient will start receiving Sorafenib on Day 4 (up to Day 7) after 1st TACE (Day 1) and will interrupt after evening dose 4 days before each next TACE and re-start Sorafenib on Day 4 (up to Day 7) after each TACE cycle.Additional sorafenib treatment is optional and will be judged by investigator in the subject's best medical interest.

Treatment:

Drug: sorafenib

Procedure: TACE
