RATIONALE: Drugs used in chemotherapy, such as talotrexin, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing.
PURPOSE: This phase I trial is studying the side effects and best dose of talotrexin in treating young patients with recurrent solid tumors or leukemia that is recurrent or does not respond to treatment.
- Estimate the maximum tolerated dose (MTD) and recommended phase II dose of talotrexin in younger patients with recurrent solid tumors or recurrent or refractory leukemia.
- Determine the toxicity of this drug in these patients.
- Determine the antitumor activity of this drug in these patients.
- Assess the tolerability of the defined MTD of this drug in these patients.
OUTLINE: This is a dose-escalation, multicenter study. Patients are stratified according to diagnosis (solid tumor vs leukemia).
- Stratum 1 (recurrent solid tumor): Patients receive talotrexin IV over 10 minutes on days 1 and 8. Treatment repeats every 21 days for up to 17 courses in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of talotrexin 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 (DLT).
- Stratum 2 (recurrent or refractory leukemia): A cohort of 3-6 patients with leukemia receive treatment as in stratum 1 at the MTD determined in stratum 1. If 2 or 3 or 2 of 6 patients experience a DLT at the solid tumor MTD, accrual is stopped.
After completion of study treatment, patients are followed for 30 days.
PROJECTED ACCRUAL: A total of 36 patients will be accrued for this study.

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.
Head and neck cancers
Cancer can occur in any of the tissues or organs in the head and neck. There are over 30 different places that cancer can develop in the head and neck area. Mouth cancers (oral cancers) - Mouth cancer can develop on the lip, the tongue, the floor...
