Chemoembolization With or Without Sorafenib Tosylate in Treating Patients With Liver Cancer That Cannot Be Removed By Surgery

Conditions

Adult Primary Hepatocellular Carcinoma | Localized Unresectable Adult Primary Liver Cancer | Recurrent Adult Primary Liver Cancer

Trial Phase

Phase 3

Trial Purpose and Description

Trial Purpose

This randomized phase III trial is studying chemoembolization and sorafenib tosylate to see how well they work compared with chemoembolization alone in treating patients with liver cancer that cannot be removed by surgery. Drugs used in chemotherapy, such as doxorubicin hydrochloride, mitomycin, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Chemoembolization kills tumor cells by carrying drugs directly into the tumor and blocking the blood flow to the tumor. Sorafenib tosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether giving chemoembolization together with sorafenib tosylate is more effective than chemoembolization alone in treating patients with liver cancer.


Trial Description

PRIMARY OBJECTIVE:

I. To compare Progression-Free Survival (PFS) of chemoembolization alone to sorafenib in combination with chemoembolization.

SECONDARY OBJECTIVES:

I. To compare overall survival (OS) of chemoembolization alone to sorafenib in combination with chemoembolization.

II. To evaluate extra-hepatic versus intra-hepatic patterns of failure. III. To determine the rates of toxicity related to Sorafenib in combination with chemoembolization.

TERTIARY OBJECTIVES:

I. To analyze the pharmacogenetic and pharmacokinetic properties of Sorafenib including angiogenesis, monooxygenases, polymorphisms and MDR.

II. ECOG secondary imaging objective: Site vs. Central evaluation of PFS. III. To determine the inter-reader concordance for response characterization at four and eight months by the European Association for the Study of Liver (EASL) criteria.

IV. To determine the value of objective tumor response at four and eight months by the EASL criteria to predict PFS (by RECIST) and OS.

V. To evaluate the effects of intra-hepatic vs. extra-hepatic progression on OS.

OUTLINE: This is a multicenter study. Patients are stratified according to macrovascular intrahepatic portal vein invasion (present vs absent), Child Pugh score (A vs B7), and chemoembolization method (doxorubicin-eluting bead vs conventional). Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive sorafenib tosylate orally (PO) twice daily in the absence of disease progression or unacceptable toxicity. Beginning within 2 weeks after a stable dose of sorafenib tosylate is reached, patients undergo transarterial chemoembolization (TACE) comprising doxorubicin hydrochloride, mitomycin C, and cisplatin (closed to accrual as of 10/1/2010); conventional chemoembolization comprising doxorubicin hydrochloride only; or chemoembolization comprising doxorubicin-eluting beads. Treatment with TACE repeats approximately every 4 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive placebo PO twice daily in the absence of disease progression or unacceptable toxicity. Beginning within 2 weeks after a stable dose of placebo is reached, patients undergo TACE as in arm I.

MAINTENANCE THERAPY: After completion of chemoembolization, patients receive sorafenib tosylate or placebo as in arm I and II in the absence of disease progression or unacceptable toxicity. Patients undergo chest, abdomen, and/or pelvis CT scans or MRI at baseline, at 4 and 8 months, and every 2 months thereafter.

Blood and tissue samples may be collected at baseline and periodically during study for pharmacogenetic and pharmacokinetic studies. After completion of study therapy, patients are followed up periodically for 4 years.
