Vandetanib to Treat Children and Adolescents With Medullary Thyroid Cancer

NCT00514046

Phase 1/2 Completed 17 enrolled National Cancer Institute (NCI)
NaSingle-groupOpen-labelTreatment

Summary

Background: * Medullary thyroid carcinoma (MTC) is common in people with a genetic disorder called multiple endocrine neoplasia (MEN). * Vandetanib is an experimental drug that blocks a defective protein receptor (rearranged during transfection (RET) receptor) found on the surface of cancer cells in people with MEN. It is thought that this protein is a primary cause of MTC in people with MEN. Objectives: * To study the activity of Vandetanib in children and adolescents with MEN-related MTC by measuring the change in tumor size, in blood levels of proteins produced the tumor (calcitonin and carcinoembryonic antigen (CEA) and in tumor-related diarrhea. * To determine the safety and tolerability of Vandetanib in children and adolescents. * To study how the body handles Vandetanib in children and adolescents. * To determine the effect of Vandetanib on the survival of children and adolescents with MTC. Eligibility: -Children and adolescents 5 to 18 years of age with MTC whose tumor cannot be surgically removed or has grown back after treatment or has metastasized (spread beyond the thyroid gland). Design: * Patients take Vandetanib once a day in 28-day cycles. The first patients enrolled in the study are started on a low dose of Vandetanib to determine tolerability. * Patients have periodic blood tests, electrocardiograms, and blood pressure measurements to look for side effects of Vandetanib. * Blood tests and imaging scans (magnetic resonance imaging (MRI), computed tomography (CT), bone and octreoscan) are done every 8 weeks for the first 32 weeks of treatment and then every 16 weeks for the duration of the treatment period. * Patients who have tumor-related diarrhea keep a daily record of the number and consistency of bowel movements.
