Brief Summary:
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. Thalidomide may stop the growth of glioblastoma multiforme by blocking blood flow to the tumor. Isotretinoin may help cells that are involved in the body's immune response to work better. Celecoxib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known which temozolomide-containing regimen is more effective in treating glioblastoma multiforme.
PURPOSE: This randomized phase II trial is studying eight different temozolomide-containing regimens to compare how well they work in treating patients who have undergone radiation therapy for glioblastoma multiforme.
Detailed Description:
OBJECTIVES:
* Compare the efficacy of adjuvant temozolomide (TMZ) alone or in combination with thalidomide and/or isotretinoin and/or celecoxib, in terms of 6-month progression-free survival, in patients who have undergone radiotherapy for supratentorial glioblastoma multiforme.
* Compare the toxicity of these regimens in these patients.
OUTLINE: This is a randomized, multicenter study. Patients are randomized to 1 of 8 treatment arms.
* Arm I: Patients receive oral temozolomide once daily on days 1-7 and 15-21.
* Arm II: Patients receive temozolomide as in arm I and oral thalidomide once daily on days 1-28.
* Arm III: Patients receive temozolomide as in arm I and oral isotretinoin twice daily on days 1-21.
* Arm IV: Patients receive temozolomide as in arm I and oral celecoxib twice daily on days 1-28.
* Arm V: Patients receive temozolomide as in arm I, thalidomide as in arm II, and isotretinoin as in arm III.
* Arm VI: Patients receive temozolomide as in arm I, thalidomide as in arm II, and celecoxib as in arm IV.
* Arm VII: Patients receive temozolomide as in arm I, isotretinoin as in arm III, and celecoxib as in arm IV.
* Arm VIII: Patients receive temozolomide as in arm I, thalidomide as in arm II, isotretinoin as in arm III, and celecoxib as in arm IV.
In all arms, treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity. Patient may receive additional courses of therapy at the discretion of the treating physician.
After completion of study treatment, patients are followed for at least 30 days and then every 3 months thereafter.
PROJECTED ACCRUAL: A total of 180 patients will be accrued for this study.
