Brief summary
RATIONALE: Diagnostic procedures, such as MRI, may help doctors learn how efaproxiral works in the brain and help plan the best treatment. PURPOSE: This clinical trial is using MRI to evaluate the effect of efaproxiral on the brain in patients with recurrent or progressive glioma receiving treatment on clinical trial NABTT-9806.
Detailed description
OBJECTIVES: * Determine whether efaproxiral has a measurable effect on the brain as shown by T2 and/or T2\* MRI in patients with recurrent or progressive malignant glioma enrolled on NABTT-9806. * Determine predicted oxygenation changes based on observed T2 MRI changes in these patients. * Determine the effects of this drug on T2 and T2\* MRI relaxation times of normal areas of the brain in these patients. * Determine baseline oxygen extraction ratios in tumors of patients treated with this drug. * Determine whether administration of this drug reveals any new tumor- or non-tumor-related abnormalities on T2 and T2\* MRI in these patients. OUTLINE: This is an open-label, multicenter, pilot study. Patients receive efaproxiral and carmustine on clinical trial NABTT-9806. During any one course of treatment on that study, patients undergo MRI before oxygen administration (baseline), before efaproxiral infusion, and then every 5 minutes until 1 hour after efaproxiral and carmustine treatment. Data is evaluated for extent and intensity of T2/T2\* changes and oxygen concentration changes in both abnormal and normal brain. PROJECTED ACCRUAL: A total of 15-48 patients will be accrued for this study within 12-24 months.
