RATIONALE: Pioglitazone hydrochloride may be effective treatment for cognitive dysfunction caused by radiation therapy.
PURPOSE: This phase I trial is studying the side effects and best dose of pioglitazone hydrochloride in preventing radiation-induced cognitive dysfunction in treating patients with brain tumors.
|Condition or disease||Intervention/treatment||Phase|
|Brain Neoplasms, Malignant Brain Neoplasms, Benign Malignant Meningioma Glioblastoma Multiforme Anaplastic Astrocytoma||Drug: pioglitazone Drug: Pioglitazone||Phase 1|
I. To evaluate the tolerability and toxicity associated with two different dose regimens of pioglitazone administered orally as a cytoprotective agent against radiation-induced brain injury.
I. To evaluate the effect of pioglitazone on glycemic levels and hemoglobin A1c values when pioglitazone is used as a cytoprotective agent concurrent with radiotherapy in normoglycemic patients.
OUTLINE: Patients undergo fractionated external beam radiotherapy, 3-D conformal radiotherapy, or intensity-modulated radiotherapy. Patients receive oral pioglitazone hydrochloride once daily before for 1 week prior to brain irradiation, during and and continuing for 6 months after completion of radiation radiotherapy. After completion of study treatment, patients are followed periodically.
