Cixutumumab and Sorafenib Tosylate in Treating Patients With Advanced Liver Cancer

Advanced Adult Hepatocellular Carcinoma Clinical Trial

Official title: A Phase I Trial of Escalating Doses of the Anti-IGF-1R Monoclonal Antibody IMC-A12 and Standard Dose Sorafenib for Treatment of Advanced Hepatocellular Carcinoma

Status Completed

Clinical Trial Summary

This phase I trial is studying the side effects and best dose of cixutumumab when given together with sorafenib tosylate in treating patients with advanced liver cancer. Monoclonal antibodies, such as cixutumumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Sorafenib tosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving cixutumumab together with sorafenib tosylate may kill more tumor cells.

Clinical Trial Description

PRIMARY OBJECTIVES:

I. To establish the maximum tolerated dose (MTD) of IMC-A12 given in conjunction with standard doses of sorafenib to patients with advanced hepatocellular carcinoma (HCC).

II. To describe the toxicity and tolerance of IMC-A12 at each dose studied in combination with standard-dose sorafenib in patients with advanced HCC.

III. To evaluate the impact of IMC-A12 on biomarkers related to the IGF-1R/IGF pathway which is thought relevant to HCC progression and drug resistance.

IV. To obtain preliminary assessments of efficacy through description of progression-free survival (PFS) and objective response rate (RR).

OUTLINE: This is a multicenter, dose-escalation study of cixutumumab followed by an extended accrual phase in which patients are treated at the maximum-tolerated dose.

Patients receive cixutumumab IV over 1 hour on days 1, 8, 15, and 22 and oral sorafenib tosylate twice daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study therapy, patients are followed up periodically. ;
