COL-3 in Treating Patients With Progressive or Recurrent Brain Tumors
RATIONALE: COL-3 may stop the growth of brain tumors by stopping blood flow to the tumor.
PURPOSE: Phase I/II trial to study the effectiveness of COL-3 in treating patients who have progressive or recurrent brain tumors following radiation therapy or chemotherapy.
- Determine the maximum tolerated dose, dose limiting toxicity, and safety profile of oral COL-3 alone or when combined with anticonvulsants known to be metabolized by CYP450 in patients with progressive or recurrent high grade anaplastic astrocytoma, anaplastic oligodendroglioma, or glioblastoma multiforme.
- Define the pharmacokinetics and pharmacodynamics of COL-3 on this schedule and determine the effects of hepatic enzyme inducing drugs, such as anticonvulsants, on the pharmacokinetics.
- Determine the response rate, disease free survival, and survival in patients treated with this regimen.
OUTLINE: This is a dose-escalation, multicenter study of COL-3. Patients are stratified by anticonvulsant (anticonvulsants that cause induction of CYP450 vs anticonvulsants that cause modest or no induction of CYP450 or no anticonvulsant).
- Phase I: Patients receive oral COL-3 daily. Treatment repeats every 4 weeks in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of COL-3 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose limiting toxicity.
- Phase II: Patients receive oral COL-3 daily at the MTD from the phase I portion of this study.
Patients are followed every 2 months until death.
PROJECTED ACCRUAL: A total of 15-18 patients will be accrued for phase I of the study and a total of 35 patients will be accrued for phase II of the study at a rate of 3 patients per month.

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.
Neuroectodermal Tumors, Primitive
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.

Autonomic Nervous System Diseases
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.
Central Nervous System
The main information-processing organs of the nervous system, consisting of the brain, spinal cord, and meninges.
Central Nervous System Venous Angioma
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.
