Brief summary
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of temozolomide plus irinotecan in treating patients who have recurrent malignant glioma.
Detailed description
OBJECTIVES: * Determine the maximum tolerated dose and dose-limiting toxicity of irinotecan when administered with temozolomide in patients with recurrent malignant glioma. * Determine the safety profile of this regimen in this patient population. * Determine the efficacy of this treatment regimen as measured by 6-month progression-free survival and objective tumor response in these patients. * Characterize the pharmacokinetics of this treatment regimen in these patients. * Determine the antitumor activity of this treatment regimen in these patients. OUTLINE: This is a multicenter, dose-escalation study of irinotecan. Patients are stratified according to concurrent enzyme-inducing anti-epileptic drugs (EIAEDs) (e.g., phenytoin, phenobarbital, carbamazepine, or primidone) (yes vs no). In phase I of the study, patients receive oral temozolomide on days 1-5 and irinotecan IV over 90 minutes on days 1 and 14. Treatment continues every 28 days for up to 1 year in the absence of disease progression or unacceptable toxicity. Patients concurrently on EIAEDs undergo dose escalation of irinotecan. Cohorts of 3 to 6 patients receive escalating doses of irinotecan until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 6 patients experience dose-limiting toxicity. In phase II of the study, patients receive the same treatment as in phase I at the MTD. Patients are followed every 2 months for 1 year, every 3 months for 1 year, every 4 months for 1 year, every 6 months until progression, and then every 4 months for survival. PROJECTED ACCRUAL: A total of 30 patients will be accrued for phase I within 10 months and 48 patients will be accrued for phase II within 6-8 months.
