Phase 2 Study of TAC-101 Combined With Transcatheter Arterial Chemoembolization (TACE) Versus TACE Alone in Japanese Patients With Advanced Hepatocellular Carcinoma

• Status: Terminated
• Trial end date: 2010-04-01
• Target enrollment: 0
• Participant gender: All

Summary

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.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Criteria

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 or by the following non-invasive criteria observed either at enrollment 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

• 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 at least 120 days before signing ICF.

3. Eligible to receive TACE and being scheduled to receive TACE.

4. Must be ≥ 20 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. Must have lesions in the liver that are confirmed nodular type with demonstrated substantial hypervascularity by CT scan or MRI both with unenhanced plus hepatic arterial phase and portal venous phases performed prior to first TACE in this study with the following tumor features:

• If there are ≥ 4 intrahepatic lesions, all lesions can be < 30 mm. or, regardless of the number of lesions, the longest diameter of at least one intrahepatic lesion is ≥ 30 mm).

8. Must have a Child-Pugh classification of ≤ 8.

9. Must have a Cancer of the Liver Italian Program (CLIP)60 score of 0, 1, 2 or 3 (Appendix B).

10. 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. Patient has ascites, pleural effusions or pericardial fluid refractory to diuretic therapy.

7. Patient has clinical symptoms of hepatic encephalopathy.

8. Patient has active or uncontrolled clinically serious infection excluding chronic hepatitis.

9. Patient has a history of gastrointestinal (GI) bleeding in last 3 months.

10. Patient has previous or concurrent malignancy except for in situ carcinoma of the cervix, or other solid tumor treated curatively and without evidence of recurrence for at least 3 years prior to the study.

11. Patient has uncontrolled metabolic disorders or other nonmalignant organ or systemic diseases or secondary effects of cancer that induce a high medical risk and/or make assessment of survival uncertain.

12. Patient has any history of deep vein thrombosis (DVT), pulmonary embolism (PE), myocardial infarction (MI), cerebrovascular accident (CVA), transient ischemic attack (TIA), unstable angina pectoris, or any other significant thromboembolic event (TE) during the last 3 years.

13. Patient has clinically significant electrocardiogram (ECG) abnormality.

14. Patient has GI disease resulting in an inability to take oral medication.

15. Patient has known allergy or hypersensitivity to TAC-101, doxorubicin, epirubicin, other anthracyclines, anthracenediones or any of the components used in the study drug formulations.

16. Patient has known hypersensitivity to iodinated contrast medium.

17. Patient is receiving therapeutic regimens of anticoagulants. However, use of low dose anticoagulants for prophylactic care of indwelling venous access device is permitted.

18. Patient is taking medication known or suspected to predispose patient to an increased risk of VTE (eg, oral contraceptives, hormone replacement therapy, megestrol acetate).
