  • Recurrent Childhood Liver


This phase II trial is studying the side effects and how well cixutumumab works in treating patients with relapsed or refractory solid tumors. 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.

Study summary:

PRIMARY OBJECTIVES: I. To determine the response rate to IMC-A12 (cixutumumab) administered in various strata of recurrent/refractory malignant solid tumors in childhood and young adulthood. II. To further define and describe the toxicities of IMC-A12. III. To further characterize the pharmacokinetics of IMC-A12. SECONDARY OBJECTIVES: I. To examine the relationship between tumor expression of IGF-I, IGF-II, and IGF-IR and response to IMC-A12. II. To determine the human anti-human antibody (HAHA) response after treatment with IMC-A12. III. To further evaluate the effect of IMC-A12 on circulating levels of proteins involved in linear growth and glucose homeostasis, including IGF-I, IGF-II, IGF-BP3, growth hormone, insulin, and C-peptide. OUTLINE: This is a multicenter study. Patients are stratified according to disease type. Patients receive cixutumumab intravenously (IV) over 1 hour on days 1, 8, 15, and 22. Treatment repeats every 28 days for up to 24 courses in the absence of disease progression or unacceptable toxicity. Patients undergo blood sample collection periodically for correlative laboratory studies. Samples are analyzed for IGF-I, IGF-II, IGF-BP3, growth hormone, insulin, and C-peptide levels and for immunogenicity.
