Brief Summary:
This phase II trial is studying how well giving O6-benzylguanine together with temozolomide works in treating young patients with recurrent or progressive gliomas or brain stem tumors. Drugs used in chemotherapy, such as O6-benzylguanine and temozolomide , work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. O6-benzylguanine may help temozolomide work better by making tumor cells more sensitive to the drug. Giving more than one drug (combination chemotherapy) may kill more tumor cells.
Detailed Description:
PRIMARY OBJECTIVES:
I. Determine the sustained objective response rate to the combination of O6-benzylguanine and temozolomide in pediatric patients with recurrent or progressive high-grade gliomas and brain stem tumors.
SECONDARY OBJECTIVES:
I. Determine the toxicity of this regimen in these patients.
OUTLINE: This is a multicenter study. Patients are stratified according to tumor type (high-grade gliomas vs brain stem tumors).
Patients receive O6-benzylguanine IV over 1 hour followed by oral temozolomide on days 1-5. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed to the earliest of 30 days following discontinuation of therapy or the initiation of additional anti-cancer therapy or death.
PROJECTED ACCRUAL: A total of 50 patients will be accrued for this study.
