Temozolomide in Treating Patients With Recurrent Glioblastoma Multiforme or Other Malignant Glioma
RATIONALE: Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.
PURPOSE: This phase II trial is studying how well temozolomide works in treating patients with recurrent glioblastoma multiforme or other malignant glioma.

|Official Title:||A Phase II Trial of Continuous Low-Dose Temozolomide for Patients With Recurrent Malignant Glioma|
- Progression-free Survival (PFS) Rate at 6 Months [ Time Frame: at 6 months ]Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.
- Overall Survival [ Time Frame: 2 years ]All patients will have their tumor measurements recorded at baseline and at the time of each MRI scan. Lesions must be measured in two dimensions. The dose of gadolinium must be held constant from scan to scan. Macdonald criteria will be used for assessment of tumor response.
|Study Start Date:||June 2007|
|Study Completion Date:||December 2013|
|Primary Completion Date:||December 2013 (Final data collection date for primary outcome measure)|
Following diagnosis of tumor recurrence or progression, all patients will receive of daily low dose temozolomide given at 50mg/m2/d without interruption. Brain imaging will be performed at baseline and every 2 months (standard of care). The treatment will be administered until development of toxicity, evidence of progression of disease or death.

- Determine the progression-free survival rate at 6 months in patients with recurrent glioblastoma multiforme or other malignant glioma treated with temozolomide.
- Determine the overall survival of patients treated with this drug.
OUTLINE: Patients receive oral temozolomide once daily in the absence of disease progression or unacceptable toxicity.
Blood samples are collected at baseline and every 2 months for 2 years for evaluation of markers of neo-angiogenesis. Samples are analyzed by protein expression, reverse-transcriptase PCR, ELISA, and western blot. (Samples are no longer being collected and tested as of 1/12/09)
