OBJECTIVES: I. Determine the maximum tolerated dose of taurolidine in patients with recurrent or progressive high-grade glioma. II. Determine the safety and toxicity of this drug in these patients. III. Determine the pharmacokinetics of this drug in these patients. IV. Determine the response in patients treated with this drug.

OUTLINE: This is a dose-escalation study. Patients receive taurolidine IV over 1-4 hours on days 1-5, 8-12, and 15-19. Treatment repeats every 6 weeks in the absence of disease progression or unacceptable toxicity. Cohorts of 1-6 patients receive escalating doses of taurolidine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 6 patients experience dose-limiting toxicity. Patients are followed monthly for 3 months.

PROJECTED ACCRUAL: A total of 4-24 patients will be accrued for this study.

DISEASE CHARACTERISTICS: Histologically confirmed glioblastoma multiforme, anaplastic astrocytoma, or gliosarcoma Recurrent or progressive disease after prior cytoreductive surgery, radiotherapy, and adjuvant chemotherapy Ineligible for any additional conventional therapeutic intervention

PATIENT CHARACTERISTICS: Age: 16 and over Performance status: Karnofsky 60-100% Life expectancy: More than 12 weeks Hematopoietic: Absolute neutrophil count greater than 1,500/mm3 Platelet count at least 100,000/mm3 Hepatic: Bilirubin less than 1.5 mg/dL AST/ALT less than 3 times upper limit of normal No indication of acute hepatitis or parenchymal liver disease No significant hepatic disease that would preclude study Renal: Creatinine less than 1.7 mg/dL No significant renal disease that would preclude study Cardiovascular: No significant cardiac disease that would preclude study Other: HIV negative No other active malignancy except curatively treated carcinoma in situ of the cervix or basal cell skin cancer No significant psychiatric disease that would preclude study No significant gastrointestinal disease that would preclude study No known hypersensitivity to taurolidine or its excipients Not pregnant or nursing Negative pregnancy test Fertile patients must use effective contraception
