RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.
PURPOSE: Phase I/II trial to study the effectiveness of CCI-779 in treating patients who have malignant glioma.
- Determine the maximum tolerated dose of CCI-779 in patients with malignant glioma.
- Determine the safety profile of this drug in these patients.
- Determine the pharmacokinetics of this drug in these patients.
- Determine the efficacy of this drug, in terms of survival and objective response, in these patients.
OUTLINE: This is a dose-escalation study. Patients in phase II are stratified according to use of enzyme-inducing antiepileptic drugs (EIAEDs) (yes vs no) and disease type (glioblastoma multiforme with stable neuro-imaging after radiotherapy vs recurrent malignant glioma). Patients in phase I must be currently receiving EIAEDs.
- Phase I: Patients receive CCI-779 IV over 30 minutes once weekly. Treatment repeats every 4 weeks in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of CCI-779 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: Patients receive CCI-779 as in Phase I. Patients who are candidates for surgical resection of recurrent disease receive CCI-779 IV over 30 minutes 2 hours prior to surgery and then once weekly, as above, once recovered from surgery.
Patients are followed for survival.
PROJECTED ACCRUAL: A total of 36 patients will be accrued for phase I of this study within 12 months. A total of 87 patients will be accrued for phase II of this study within 12 months.

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.
A vascular anomaly characterized by a radial or wedge-shaped arrangement of dilated VEINS draining into a larger vein in the brain, spinal cord, or the meninges. Veins in a venous angioma are surrounded by normal nervous tissue, unlike a CENTRAL NERVOUS SYSTEM CAVERNOUS HEMANGIOMA that lacks intervening nervous tissue. Drainage of venous angioma is fully integrated with the body's venous system, therefore, in most cases there is no clinical signs and rare bleeding.
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...
