Brief Summary: 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 This phase III trial is studying how well giving gefitinib together with radiation therapy works in treating children with newly diagnosed glioma
Detailed Description: PRIMARY OBJECTIVES

I To define the safety of gefitinib administered in conjunction with irradiation in children with newly diagnosed non-disseminated diffuse intrinsic brainstem gliomas and newly diagnosed incompletely resected supratentorial malignant gliomas STMG not receiving enzyme inducing anticonvulsant drugs EIACDs

II To define the safety of gefitinib in children with newly diagnosed incompletely resected STMG receiving EIACDs

III To assess the safety and efficacy of gefitinib given with radiation therapy in children newly diagnosed with a brainstem glioma as measured by progression-free survival and to estimate the survival distribution

SECONDARY OBJECTIVES

I To compare hemodynamic magnetic resonance MR parameters to metabolic fludeoxyglucose F 18 FDG-positron emission tomography PET scanning and correlate both with clinical response or progression in this population

II To characterize the expression of ErbB1 receptors in tissue from STMG patients using immunohistochemistry and western blot assays

III To characterize the pharmacokinetics of gefitinib in the above patient groups and determine the effects of EIACD on the pharmacokinetics

IV To explore the pharmacogenetic polymorphisms for gefitinib eg CYP3A45 and BCRP and relate them to gefitinib pharmacokinetics and pharmacodynamics phenotype-genotype

OUTLINE This is a multicenter dose-escalation study of gefitinib Phase I closed to accrual effective 10272003 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 10272003 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 or the recommended Phase-II dose is determined additional patients who have newly diagnosed brain stem gliomas BSG are treated at the MTD or the recommended Phase-II dose

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 Considering the seven dose levels to be investigated in three strata where each dose level can accrue up to six patients a total of 126 patients 42 for each strata may be accrued for this study within 2 years Phase I closed to accrual effective 10272003 A total of 40 patients including the patients treated at the maximum tolerated dose or the recommended Phase-II dose during Phase I will be accrued for phase II of this study within 10 months
