RATIONALE: Everolimus may stop the growth of tumor cells by stopping blood flow to the tumor. Gefitinib may stop the growth of tumor cells by blocking the enzymes necessary for their growth. Combining everolimus with gefitinib may kill more tumor cells.
PURPOSE: This phase I/II trial is studying the side effects and best dose of everolimus when given together with gefitinib and to see how well they work in treating patients with progressive glioblastoma multiforme or (progressive metastatic prostate cancer closed to accrual 10/19/06).
- Determine the maximum tolerated dose of everolimus when given in combination with gefitinib in patients with progressive glioblastoma multiforme or (progressive castrate metastatic prostate cancer -closed to accrual as of 10/19/2006). (Phase I)
- Determine the safety and efficacy of this regimen in patients with progressive giloblastoma multiforme or (progressive castrate metastatic prostate cancer - closed to accrual as of 10/19/2006). (Phase II)
- Determine whether a pharmacokinetic interaction exists between everolimus and gefitinib in patients treated with this regimen.
- Determine the association between clinical outcomes and markers that may predict sensitivity of a tumor in patients treated with this regimen.
- Determine the pharmacodynamic effects of this regimen on post-therapy tumor specimens and peripheral blood mononuclear cells from these patients.
OUTLINE: This is a phase I, open-label, non-randomized, dose-escalation study of everolimus followed by a phase II study.
- Phase I: Patients receive oral everolimus on day 1 and oral gefitinib once daily on days 8-21. Beginning on day 22, patients receive oral everolimus once weekly and oral gefitinib once daily. Treatment with the combination continues in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of everolimus 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 (prostate cancer patients only) (closed to accrual as of 10/19/2006): Patients receive oral everolimus (at the MTD determined in phase I) once weekly and oral gefitinib once daily. Treatment continues in the absence of disease progression or unacceptable toxicity.
PROJECTED ACCRUAL: A total of 3-18 patients will be accrued for the phase I portion of this study within 6 months. A total of 27-40 patients will be accrued for the phase II portion of this study within 8 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...
