Gefitinib Plus Temozolomide in Treating Patients With Malignant Primary Glioma

2014-08-27 03:56:27 | BioPortfolio

Summary

RATIONALE: Biological therapies such as gefitinib may interfere with the growth of cancer cells and slow the growth of the tumor. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining gefitinib with chemotherapy may kill more tumor cells.

PURPOSE: Phase I trial to study the effectiveness of combining gefitinib with temozolomide in treating patients who have malignant primary glioma.

Description

OBJECTIVES:

- Determine the maximum tolerated dose of gefitinib when given in combination with temozolomide in patients with malignant primary glioma.

- Determine the toxic effects of this regimen in these patients.

- Determine the pharmacokinetics of this regimen in these patients.

OUTLINE: This is a multicenter, dose-escalation study of gefitinib. Patients are stratified according to use of concurrent enzyme-inducing anti-epileptic drugs (yes vs no).

Patients receive oral gefitinib once daily on days 1-35 and oral temozolomide once daily on days 8-12 for the first course only. For the second and subsequent courses, patients receive oral gefitinib once daily on days 1-28 and oral temozolomide once daily on days 1-5. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of gefitinib 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.

Patients are followed every 2 months for 1 year and then every 3-6 months thereafter.

PROJECTED ACCRUAL: Approximately 3-42 patients will be accrued for this study within 1-14 months.

Medical and Biotech [MESH] Definitions

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. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, p2059)

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.
