Summary

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Erlotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. It may also make tumor cells more sensitive to radiation therapy. Giving radiation therapy together with erlotinib may kill more tumor cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of erlotinib when given together with radiation therapy and to see how well they work in treating young patients with newly diagnosed glioma.

Detailed description

OBJECTIVES: Primary * Determine the maximum tolerated dose and dose-limiting toxicity of erlotinib when administered during and after radiotherapy in young patients with newly diagnosed high-grade glioma and unfavorable low-grade glioma. * Determine the 1- and 2-year progression-free survival of patients treated with this regimen. Secondary * Determine the toxic effects of this regimen in these patients. * Correlate genetic abnormalities in epidermal growth factor receptor (EGFR) and components of downstream pathways with treatment response in patients treated with this regimen. * Determine the ability of erlotinib to inhibit EGFR signaling in patients with high-grade glioma who require second surgery. * Determine the pharmacokinetics of erlotinib and its metabolites in these patients. * Correlate plasma and cerebrospinal fluid levels of vascular endothelial growth factor and basic fibroblast growth factor with tumor response in patients treated with this regimen. * Correlate irradiation dosimetry with patterns of failure, standard and investigational imaging, and toxicity in patients treated with this regimen. OUTLINE: This is a phase I dose-escalation study of erlotinib followed by a phase II study. * Phase I: Patients undergo radiotherapy once daily, 5 days week, for approximately 6½ weeks. Beginning on the first day of radiotherapy, patients receive oral erlotinib once daily for up to 2 years. Cohorts of patients receive escalating doses of erlotinib until the maximum tolerated dose (MTD) is determined. * Phase II: Patients will receive erlotinib as in phase I at the MTD and undergo radiotherapy as in phase I. PROJECTED ACCRUAL: A total of 75-80 patients (15-20 for the phase I portion and 60 for the phase II portion) will be accrued for this study.

Interventions

Type	Name	Description
DRUG	Erlotinib hydrochloride	This study has 2 components: a Phase I component which estimated the MTD and DLT(s) of erlotinib given once a day during and after conventionally fractionated RT for a period of 8 weeks (DLT-evaluation period), followed by continuous administration of this medication for up to 3 years; and a Phase II component where erlotinib will be given at the MTD during and after RT for 2 years. The recommended dose of erlotinib for the Phase II component of the current study is 120mg/m2 per day (maximum dose of 200mg per day).
