The purpose of this study is to evaluate the efficacy and safety of TAC-101 after Transcatheter Arterial Chemoembolization (TACE) in patients with advanced, unresectable hepatocellular carcinoma (HCC) who are being scheduled for TACE.

Clinical Details

Official title: Randomized, Double-Blind, Placebo-Controlled, Phase 2 Study of TAC-101 in Combination With Transcatheter Arterial Chemoembolization (TACE) Versus TACE Alone in Asian Patients With Advanced Hepatocellular Carcinoma

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment

Primary outcome: radiologically proven progression-free survival (PFS)

Secondary outcome:

Overall survival (OS)

Time to appearance of remote new lesions (TTNLr)

Objective tumor response rate (ORR) according to RECIST criteria (CR + PR)

Effects on the plasma levels of alpha-fetoprotein (AFP and AFP-L3)

Number of post-randomization TACE procedures

The adverse event (AE) profile and tolerability of TAC-101 therapy with TACE versus placebo therapy with TACE

The relationship between the PK of TAC-101 and its metabolites and safety and efficacy parameters, including hepatic function

The biological effects of TAC-101 on selected RAR-related factors and growth factor VEGF-A

The relationship between tumor gene expression (mRNA expression) of co-activators and co-repressors and efficacy parameters

Detailed description: Transcatheter arterial chemoembolization (TACE) is a commonly performed procedure in the treatment of unresectable liver tumors for selected patients. TACE is a major palliative treatment for these patients. Most patients will have intrahepatic recurrence of their tumors following TACE. In this study, which will be conducted in Asian countries excluding Japan, TAC-101 will be administered as maintenance therapy after TACE compared with placebo therapy after TACE to patients with advanced HCC who are being scheduled for TACE and who either have not had any previous TACE procedures or who received their most recent TACE at least 120 days before signing the Informed Consent Form (ICF) and the TACE procedure resulted in complete necrosis, to determine if TAC-101 will enhance the benefits of TACE.


Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.


Inclusion Criteria:

- A patient must meet all of the following inclusion criteria to be eligible for

enrollment in this study and before undergoing the first TACE procedure of this study: 1. Has an HCC diagnosis by histology (can not have a mixed tumor type such as HCC and cholangiocarcinoma) OR by the following non-invasive criteria observed either within 14 days prior to first TACE or in the past.

- One imaging technique (CT scan or magnetic resonance imaging [MRI] both

with unenhanced plus hepatic arterial phase and portal venous phases) showing characteristic features in a focal lesion > 20 mm with arterial vascularization, or

- Two dynamic imaging techniques (CT scan, MRI with unenhanced plus hepatic

arterial phase and portal venous phases) showing characteristic features coincidentally in a focal lesion 10-20 mm with arterial vascularization. 2. Is TACE naïve or has received the most recent TACE procedure, which showed complete necrosis after treatment, at least 120 days before signing ICF. 3. Eligible to receive TACE and being scheduled to receive TACE. 4. Is ≥ 18 years of age. 5. Is not amenable to treatment with curative surgery, transplant, or percutaneous ablation, including RFA, percutaneous ethanol injection therapy (PEIT) and percutaneous microwave coagulation therapy (PMCT). 6. Have at least 1 measurable lesion that is ≥10 mm in size. Measurable lesions must be confirmed nodular type (not including only infiltration type) which demonstrated substantial hypervascularity by CT scan or MRI both with unenhanced plus hepatic arterial phase and portal venous phases. All measurable lesions must be targeted by the first TACE in this study

- If there are ≥ 4 intrahepatic lesions, at least 1 must be ≥10 mm and all

lesions must be <100 mm.

- If there are < 4 intrahepatic lesions, at least one must be ≥ 30 mm and all

lesions must be <100 mm.

- No vascular invasion in main trunk and first order branch of portal vein or

other large vessels (hepatic vein or inferior vena cava).

- No extrahepatic tumor spread

7. Absence of extrahepatic abdominal tumors must be confirmed. 8. Has adequate organ function as defined by the following criteria:

- Aspartate transaminase (AST) < 5 x ULN

- Alanine transaminase (ALT) < 5 x ULN

- Total bilirubin < 2. 0 mg/dL

- Albumin > 2. 8 g/dL

- Serum creatinine < 1. 5 mg/dL

- International normalized ratio (INR) ≤ 2. 0

- Triglyceride ≤ 2. 5 x ULN.

9. Has a Child-Pugh classification of ≤ 8. 10. Has a Cancer of the Liver Italian Program (CLIP)68 score of 0, 1, 2 or 3. 11. Has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1. 12. Is willing and able to comply with schedule visits, treatment plans, laboratory tests, and other study procedures. 13. Provides written informed consent prior to the implementation of any study assessment or procedures. Exclusion Criteria:

- Patients will be excluded from participation in the study if any of the following

conditions are observed before undergoing the first TACE procedure: 1. Has only infiltration type of HCC. 2. Has extrahepatic metastasis of HCC including regional lymph node metastases. 3. Has had systemic chemotherapy (eg, sorafenib, doxorubicin), immunotherapy, or biologic therapy or radiotherapy for HCC, or treatment with TAC-101. 4. Received treatment with any of the following within the specified time frame:

- Any major surgical procedure within 28 days prior to signing the ICF

- Any red blood cell or thrombocyte transfusion, treatment with blood
