Imatinib Mesylate and Hydroxyurea in Treating Patients With Recurrent or Progressive Meningioma

• Status: Completed
• Trial end date: 2010-10-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Imatinib mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as hydroxyurea, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving imatinib mesylate together with hydroxyurea may kill more tumor cells.

PURPOSE: This phase II trial is studying how well giving imatinib mesylate together with hydroxyurea works in treating patients with recurrent or progressive meningioma.

• Phase: Phase 2
