Trial Description

Summary

RATIONALE: Imatinib mesylate may interfere with the growth of tumor cells and slow the growth of the tumor.

PURPOSE: Phase II trial to study the effectiveness of imatinib mesylate in treating patients who have gliomas.

Further Study Information

OBJECTIVES:

• Determine the therapeutic activity of imatinib mesylate (in terms of objective response and progression-free survival at 6 months) in patients with gliomas.

• Determine the safety of this drug in these patients.

• Determine the pharmacokinetics of this drug in these patients.

OUTLINE: This is a multicenter study. Patients are stratified according to glioma (glioblastoma multiforme vs anaplastic oligodendroglioma or mixed oligoastrocytoma vs anaplastic astrocytoma or recurrent low-grade astrocytoma).

Patients receive oral imatinib mesylate once or twice daily. Treatment repeats every 4 weeks for up to 9 courses in the absence of disease progression or unacceptable toxicity.

Patients are followed every 2 months for 6 months and then every 3 months thereafter.

PROJECTED ACCRUAL: A total of 77 patients (29 patients with glioblastoma multiforme, 24 patients with anaplastic oligodendroglioma or mixed oligoastrocytoma, and 24 patients with anaplastic astrocytoma or recurrent low-grade astrocytoma) will be accrued for this study.
