AZD6244 Hydrogen Sulfate for Children With Nervous System Tumors

Summary

Background: \- Plexiform neurofibromas are tumors that grow in and around nerves. The only way to treat them is with surgery. Some of these tumors cannot be completely removed. The tumors may be too large, too numerous, or in a bad location for surgery. An experimental drug called AZD6244 hydrogen sulfate may be able to prevent the tumors from growing, slow down their growth, or shrink them. This drug has been tested in adults with cancer and in children with some types of brain cancer. This study will test how well this drug works with these types of tumors. Objectives: \- To study the safety and effectiveness of AZD6244 hydrogen sulfate in children and young adults with plexiform neurofibromas that cannot be completely removed by surgery. Eligibility: \- Children and young adults between 12 and 18 years of age who have plexiform neurofibromas that cannot be completely removed by surgery. Design: * Patients will be screened with a physical exam, medical history, blood tests, and imaging studies. * They will take the study drug twice a day with 8 ounces of water, every day for 28-day cycles of treatment. During study visits, participants will have blood and urine tests and physical exams. They will also have imaging studies to examine the tumor sizes and locations. They will answer questions about their health. They may have other tests as needed. * Participants will continue to receive the study drug as long as they have no severe side effects and the disease is not getting worse.
