Study Details

Study Description

Brief Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of combining carmustine and O6-benzylguanine in treating patients who have recurrent or progressive glioma.

Condition or Disease	Intervention/Treatment	Phase
Brain and Central Nervous System Tumors	Drug: O6-benzylguanine Drug: carmustine	Phase 2

Detailed Description

OBJECTIVES: I. Determine the activity of carmustine and O6-benzylguanine in patients with recurrent or progressive glioblastoma multiforme, anaplastic astrocytoma, or gliosarcoma resistant to nitrosourea. II. Determine the toxic effects of this regimen in these patients.

OUTLINE: Patients receive O6-benzylguanine IV over 1 hour, followed 1 hour later by carmustine IV over 1 hour on day 1. Treatment repeats every 6 weeks in the absence of disease progression or unacceptable toxicity.

PROJECTED ACCRUAL: A total of 18-32 patients will be accrued for this study within 12-18 months.
