Carboxyamidotriazole Plus Radiation Therapy in Treating Patients With Newly Diagnosed Supratentorial Glioblastoma Multiforme

2014-07-24 14:35:49 | BioPortfolio

Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining radiation therapy with chemotherapy may kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of carboxyamidotriazole plus radiation therapy in treating patients who have newly diagnosed supratentorial glioblastoma multiforme.

Description

OBJECTIVES: I. Determine overall survival rate and duration of disease free progression in patients with newly diagnosed supratentorial glioblastoma multiforme treated with carboxyamidotriazole and radiotherapy. II. Evaluate the toxicities of this combination regimen in this patient population. III. Determine the correlations between pharmacokinetic parameters and toxicity and/or drug activity of this regimen in these patients.

OUTLINE: This is a multicenter study. Patients receive induction therapy consisting of radiotherapy once daily 5 days a week plus oral carboxyamidotriazole once daily for 6 weeks followed by carboxyamidotriazole alone daily for 4 weeks. Patients continue on oral carboxyamidotriazole once daily as maintenance therapy in the absence of disease progression or unacceptable toxicity. Patients are followed monthly for survival.

PROJECTED ACCRUAL: A total of 54 patients will be accrued for this study over 1.5 years.

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.
