RATIONALE: Biological therapies such as gefitinib may interfere with the growth of the tumor cells and may make the tumor cells more sensitive to radiation therapy. PURPOSE: This phase I/II trial is studying how well giving gefitinib together with radiation therapy works in treating children with newly diagnosed glioma.

Study summary:

OBJECTIVES: - Determine the safety and maximum tolerated dose of gefitinib when combined with brain irradiation in children with newly diagnosed brain stem gliomas or incompletely resected supratentorial malignant gliomas (STMG) who are not receiving concurrent enzyme-inducing anticonvulsant drugs (EIACDs). (Phase I closed to accrual effective 10/27/2003). - Determine the safety of this regimen in children with newly diagnosed incompletely resected STMG who are receiving concurrent EIACDs. (Phase I closed to accrual effective 10/27/2003). - Determine the safety and efficacy of this regimen in children with newly diagnosed poor-prognosis brain stem glioma.(Phase II) - Correlate the hemodynamic MRI parameters to metabolic fludeoxyglucose F 18-positron emission tomography scanning with clinical response or progression in patients treated with this regimen. - Determine the pharmacokinetics of gefitinib, including the effects of EIACDs on the pharmacokinetics of this drug, in these patients. OUTLINE: This is a multicenter, dose-escalation study of gefitinib (Phase I closed to accrual effective 10/27/2003). Patients are stratified according to the following: - Stratum 1A: Intrinsic brain stem glioma; not receiving concurrent enzyme-inducing anticonvulsant drugs (EIACDs) - Stratum 1B: Incompletely resected supratentorial malignant gliomas (STMG); not receiving concurrent EIACDs - Stratum 2: Incompletely resected STMG; receiving concurrent EIACDs - Phase I portion (patients in strata 1A, 1B, and 2) (phase I closed to accrual effective 10/27/2003): Patients receive oral gefitinib once daily. Treatment repeats every 4 weeks for 13 courses (1 year). Patients also receive standard brain irradiation once daily, 5 days a week, for 6 weeks beginning concurrently with initiation of the first course of gefitinib. Treatment continues in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of gefitinib until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity. - Phase II portion (patients in stratum 1A): Once the MTD is determined, additional patients are treated at the MTD. Patients are followed for three months after the last protocol treatment for those enrolled strictly on the phase I component. Patients contributing to the phase II portion are followed until the earliest of date of death or three years after initiation of protocol therapy. PROJECTED ACCRUAL: A total of 170 patients (120 for stratum 1A and 50 for strata 1B and 2 combined) may be accrued for this study within 2 years. (Phase I closed to accrual effective 10/27/2003). A total of 40 patients will be accrued for phase II of this study within 10 months.
