Pioglitazone Hydrochloride in Preventing Radiation-Induced Cognitive Dysfunction in Treating Patients With Brain Tumors
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.

|Official Title:||Use of Pioglitazone for the Prevention of Radiation-Induced Cognitive Dysfunction|
- Best tolerated dose of 2 different doses of orally administered pioglitazone [ Time Frame: From first dose to 1 day after last dose of drug ]
- Toxicities associated with both dose levels [ Time Frame: From first dose to 1 day after last dose of drug ]
- 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. [ Time Frame: From first dose to 1 day after last dose of drug ]

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.
