Filter by:Background: - AZD6244 is an experimental drug designed to prevent tumor growth and shrink existing tumors. It has been studied in adults with cancer, but it has not been studied in children with cancer. Researchers want to see if AZD6244 is a safe and effective treatment for older children and young adults who have gliomas (brain tumors) that have not responded to standard treatments. Objectives: - To test the safety and effectiveness of AZD6244 in older children and young adults who have gliomas that have not responded to standard treatments. Eligibility: - People between 12 and 21 years of age who have gliomas that have not responded to standard treatments. Design: - Participants will be screened with a medical history and physical exam. They will also have blood tests and tumor imaging studies. Those in the study may also have their spinal fluid tested to see whether the cancer has spread to other parts of the nervous system. - Participants will take AZD6244 as a capsule. It must be swallowed whole on an empty stomach twice a day for 28 days. Those in the study will have up to 13 cycles (4 weeks each) of treatment (1 year). - Participants will keep a diary to record doses taken and any side effects of the treatment. - Participants will have frequent blood tests and imaging studies.
The high-grade malignant brain tumors, glioblastoma multiforme (GBM) and anaplastic astrocytoma (AA), comprise the majority of all primary brain tumors in adults. This group of tumors also exhibits the most aggressive behavior, resulting in median overall survival durations of only 9-12 months for GBM, and 3-4 years for AA. Initial therapy consists of either surgical resection, external beam radiation or both. All patients experience a recurrence after first-line therapy, so improvements in both first-line and salvage therapy are critical to enhancing quality-of-life and prolonging survival. It is unknown if currently used intravenous (IV) therapies even cross the blood brain barrier (BBB). The investigators have shown in a previous phase I trial that a single Super-selective Intraarterial Cerebral Infusion (SIACI) of Bevacizumab (up to 15mg/kg) is safe and effective in the treatment of recurrent GBM. Therefore, this phase I/II clinical research trial is an extension of that trial in that the investigators seek to test the hypothesis that repeated dosing of intraarterial Bevacizumab is safe and effective in the treatment of recurrent malignant glioma. By achieving the aims of this study the investigators will also determine if IV therapy with Bevacizumab should be combined with repeated selected intraarterial Bevacizumab to improve progression free and overall survival. The investigators expect that this project will provide important information regarding the utility of repeated SIACI Bevacizumab therapy for malignant glioma, and may alter the way these drugs are delivered to the patients in the near future.
RATIONALE: Antineoplastons are naturally-occurring substances that may also be made in the laboratory. Antineoplastons may inhibit the growth of cancer cells. PURPOSE: This phase II trial is studying how well antineoplaston therapy works in treating patients with residual or recurrent anaplastic astrocytoma.

PURPOSE: This phase II trial is studying how well antineoplaston therapy works in treating patients with anaplastic astrocytoma that has not responded to previous treatment.
