CCI-779 in Treating Patients With Recurrent Glioblastoma Multiforme

Phase II trial to study the effectiveness of CCI-779 in treating patients who have recurrent glioblastoma multiforme. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.

OBJECTIVES:

I. Determine the efficacy of CCI-779, in terms of the percentage of patients who are progression-free at 6 months, time to progression, and time to death, in patients with recurrent glioblastoma multiforme.

II. Determine the toxic effects of this drug in these patients. III. Correlate molecular alterations in the tumors of these patients with response to treatment with this drug.

OUTLINE: This is a multicenter study. Patients are stratified according to concurrent P450 anticonvulsant use (yes vs no).

Patients receive CCI-779 IV over 30 minutes once weekly for 4 weeks. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.

Patients are followed every 6 months for 5 years and then annually for up to 10 years.

PROJECTED ACCRUAL: A total of 63 patients will be accrued for this study within 39 months.
