SarCNU in Treating Patients With Recurrent Malignant Glioma

OBJECTIVES:

• Determine the efficacy of SarCNU, in terms of objective response and duration of response, in patients with recurrent malignant gliomas.
• Determine the qualitative and quantitative toxic effects of this drug in these patients.
• Determine the time to progression and survival of patients treated with this drug.

OUTLINE: This is a multicenter study.

Patients receive oral SarCNU on days 1, 5, and 9. Treatment repeats every 6 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity.

Patients are followed at 4 weeks and then every 3 months thereafter.

PROJECTED ACCRUAL: A total of 15-30 patients will be accrued for this study within 12-18 months.
