About

RATIONALE: Bortezomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. 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. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving bortezomib together with temozolomide and radiation therapy may kill more tumor cells and allow doctors to save the part of the body where the cancer started.

PURPOSE: This phase II trial is studying the side effects and how well bortezomib works when given together with temozolomide and regional radiation therapy in treating patients with newly diagnosed glioblastoma multiforme or gliosarcoma.

Full description

OBJECTIVES:

Primary

• Estimate the overall survival at 2 years of patients with newly diagnosed glioblastoma multiforme treated with bortezomib in combination with temozolomide and regional radiotherapy followed by maintenance therapy comprising bortezomib and temozolomide.

Secondary

• Investigate further the safety and tolerability of this regimen in these patients.
• Determine the molecular characterization of tumor tissue and correlate these findings with response.

OUTLINE: This is a multicenter study.

• Adjuvant chemotherapy: Patients receive bortezomib IV on days 1, 4, 8, 11, 29, 32, 36, and 39 and oral temozolomide on days 1-42. Patients undergo external-beam fractionated regional radiotherapy 5 days a week for 6 weeks in the absence of disease progression or unacceptable toxicity.
• Maintenance: Beginning 2-6 weeks after radiotherapy, patients receive bortezomib IV on days 1, 4, 8, and 11 and oral temozolomide on days 1-5. Treatment repeats every 28 days for up to 24 courses in the absence of disease progression or unacceptable toxicity.

Tumor tissue samples are collected at baseline (from surgery) and periodically during study for further analysis.

After completion of study therapy, patients are followed up periodically.

Enrollment: 24 patients
