Brief Summary:

RATIONALE: Drugs used in chemotherapy such as talampanel use different ways to stop tumor cells from dividing so they stop growing or die.

PURPOSE: This phase II trial is studying how well talampanel works in treating patients with recurrent, progressive high-grade glioma.

Condition or disease Intervention/treatment Phase
Brain and Central Nervous System Tumors Drug: talampanel Phase 2

Detailed Description:


  • Determine the efficacy of talampanel, in terms of 6-month progression-free survival, in patients with recurrent high-grade gliomas.
  • Determine, preliminarily, the toxic effects of this drug in these patients.
  • Determine, preliminarily, the quality of life of patients treated with this drug.
  • Determine the pharmacokinetics of this drug in patients who are and who are not receiving enzyme-inducing antiepileptic drugs.

OUTLINE: Patients are stratified according to type of glioma (anaplastic astrocytoma vs glioblastoma multiforme). Patients in each stratum are assigned to 1 of 3 treatment groups according to concurrent enzyme-inducing antiepileptic drug use (yes, no, or valproic acid).

Patients in each group receive different doses of oral talampanel 3 times daily on days 1-42. Courses repeat every 42 days in the absence of disease progression or unacceptable toxicity.

Quality of life is assessed at baseline, every 3 weeks during the first course, every 6 weeks before all subsequent courses, and then within 2 weeks of study completion.

Patients are followed within 2 weeks.

PROJECTED ACCRUAL: A total of 91 patients (50 with anaplastic astrocytoma and 41 with glioblastoma multiforme) will be accrued for this study within 1 year.
