Condition(s) targeted: Advanced Hepatocellular Carcinoma

Intervention: TAC-101 (Drug); Placebo (Drug)

Phase: Phase 2

Status: Terminated

Sponsored by: Taiho Oncology, Inc.

Official(s) and/or principal investigator(s):
Fabio Benedetti, MD, Study Director, Affiliation: Taiho Oncology, Inc.


The purpose of this study is to determine whether TAC-101 combined with Transcatheter Arterial Chemoembolization (TACE) is more effective than TACE alone in slowing tumor activity in patients with advanced hepatocellular carcinoma. The study is also looking at the safety of TAC-101 in combination with TACE.

Clinical Details

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

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

Primary outcome: Time to appearance of new lesions (TTNL)

Secondary outcome:

Overall survival (OS)

Radiologic progression-free survival (PFS)

Objective tumor response rate (ORR) according to Response Evaluation Criteria in Solid Tumors (RECIST) criteria

Effects on plasma levels of the tumor marker alpha-fetoprotein (AFP)

Adverse event profile and tolerability of TACE with TAC-101 therapy versus TACE with placebo therapy

The relationship between the PK of TAC-101 and its metabolites (blood sampling for PK is optional), and safety and efficacy parameters, including hepatic function

The effects on selected RAR-related factors and a selected growth factor

Detailed description: Advanced metastatic hepatocellular carcinoma (HCC) is not treatable by surgical approaches or locoregional therapies such as hepatic artery hemoembolization or radiofrequency ablation (RFA) which are effective in controlling localized tumors. Transcatheter arterial chemoembolization (TACE) is the most commonly performed procedure in the treatment of unresectable liver tumors for selected patients. The TACE procedure delivers highly concentrated drugs to the tumor itself and arrests blood flow. Most patients will have intrahepatic recurrence of their tumors following TACE. Studies of TAC-101, a synthetic retinoid, indicate that although TAC-101 may not induce tumor regression, it appears to have a stabilizing effect, prolonging survival over what was expected historically. This study is designed as a randomized, double-blind, placebo-controlled, parallel-group, phase 2 study in patients with advanced HCC who have undergone a TACE procedure, which will be conducted at multiple sites in Japan, to determine if administration of TAC-101 will enhance the benefits of the TACE procedure.

arterial phase and portal venous phases) showing characteristic features coincidentally in a focal lesion 10-20 mm with arterial vascularization. 2.

Must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1. 11. Must be willing and able to comply with schedule visits, treatment plans, laboratory tests, and other study procedures. 12. Must provide 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. Patient has longest diameter of intrahepatic lesion ≥ 100 mm. 2. Patient has only infiltration type of HCC. 3. Patient has extrahepatic metastasis of HCC including regional lymph node metastases (including in lymph nodes and organs). 4. Patient had systemic chemotherapy (eg, sorafenib, doxorubicin), immunotherapy, or biologic therapy or radiotherapy for HCC, or treatment with TAC-101. 5. Patient 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 transfusion, treatment with blood component preparation, albumin preparation, and granulocyte colony stimulating factor (G-CSF) within 14 days prior to signing the ICF; Any local therapy such as alcohol injection, radiofrequency/ultrasound ablation, intraarterial chemotherapy (transcatheter arterial injection) for HCC performed within 28 days prior to signing the ICF; Any investigational agent within 28 days prior to signing the ICF. 6.
