RATIONALE: Imatinib mesylate may stop the growth of tumor cells by blocking the enzymes necessary for tumor cell growth.
PURPOSE: This phase I/II trial is studying the side effects and best dose of imatinib mesylate and to see how well it works in treating patients with a recurrent brain tumor that has not responded to previous surgery and radiation therapy.
- Determine the maximum tolerated dose of imatinib mesylate in patients with recurrent oligodendroglioma or mixed oligoastrocytoma who are currently on enzyme-inducing anticonvulsant therapy. (Phase I)
- Determine the efficacy of imatinib mesylate, as measured by response, survival, and progression-free survival, in patients with recurrent oligodendroglioma or mixed oligoastrocytoma. (Phase II)
- Compare pilot data of patients who have undergone > 2 prior chemotherapy regimens for recurrent, progressive, or mixed oligodendroglioma with traditional patients with recurrent or mixed oligodendroglioma. (Phase II and pilot study)
- Determine the toxicity and safety of this drug in these patients. (Phases I, II, and pilot study)
- Correlate, preliminarily, 1p/19q alterations, alpha-PDFGR gene amplification, and levels of related downstream signaling elements in tumor tissue with clinical response in patients treated with this drug. (Phases I, II, and pilot study)
OUTLINE: This is a multicenter, phase I, dose-escalation study followed by a phase II and a pilot study.
- Phase I: Patients receive oral imatinib mesylate twice daily for 4 weeks. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of imatinib mesylate until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.
- Phase II:
- Group 1 (concurrent enzyme-inducing anticonvulsants [EIACs]): Patients receive oral imatinib mesylate, at the MTD determined in phase I, twice daily for 4 weeks.
- Group 2 (non EIACs): Patients receive oral standard-dose imatinib mesylate twice daily for 4 weeks.
In both groups, treatment repeats every 4 weeks in the absence of disease progression or unacceptable toxicity.
- Pilot study: Patients are stratified and assigned to treatment groups as in phase II. Patients receive oral imatinib as in phase II.
Patients are followed every 2 months.
PROJECTED ACCRUAL: A total of 93 patients will be accrued to this study.

A tyrosine kinase inhibitor and ANTINEOPLASTIC AGENT that inhibits the BCR-ABL kinase created by chromosome rearrangements in CHRONIC MYELOID LEUKEMIA and ACUTE LYMPHOBLASTIC LEUKEMIA, as well as PDG-derived tyrosine kinases that are overexpressed in gastrointestinal stromal tumors.
Neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum. Brain neoplasms are subdivided into primary (originating from brain tissue) and secondary (i.e., metastatic) forms. Primary neoplasms are subdivided into benign and malignant forms. In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain.
A group of malignant tumors of the nervous system that feature primitive cells with elements of neuronal and/or glial differentiation. Use of this term is limited by some authors to central nervous system tumors and others include neoplasms of similar origin which arise extracranially (i.e., NEUROECTODERMAL TUMORS, PRIMITIVE, PERIPHERAL). This term is also occasionally used as a synonym for MEDULLOBLASTOMA. In general, these tumors arise in the first decade of life and tend to be highly malignant.

Diseases of the parasympathetic or sympathetic divisions of the AUTONOMIC NERVOUS SYSTEM; which has components located in the CENTRAL NERVOUS SYSTEM and PERIPHERAL NERVOUS SYSTEM. Autonomic dysfunction may be associated with HYPOTHALAMIC DISEASES; BRAIN STEM disorders; SPINAL CORD DISEASES; and PERIPHERAL NERVOUS SYSTEM DISEASES. Manifestations include impairments of vegetative functions including the maintenance of BLOOD PRESSURE; HEART RATE; pupil function; SWEATING; REPRODUCTIVE AND URINARY PHYSIOLOGY; and DIGESTION.
The main information-processing organs of the nervous system, consisting of the brain, spinal cord, and meninges.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
