Everolimus, Temozolomide, and Radiation Therapy in Treating Patients With Newly Diagnosed Glioblastoma

• Status: Completed
• Trial end date: 2019-11-15
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking some of the blood flow to the tumor. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving everolimus together with temozolomide and radiation therapy may kill more tumor cells.

PURPOSE: This phase I/II trial is studying the side effects and best dose of everolimus when given together with temozolomide and radiation therapy in treating patients with newly diagnosed glioblastoma.
