Enzastaurin and Temozolomide in Treating Patients With Primary Gliomas

• Status: Unknown status
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Enzastaurin 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. Giving enzastaurin together with temozolomide may kill more tumor cells.

PURPOSE: This phase I trial is studying the side effects and best dose of enzastaurin when given together with temozolomide in treating patients with primary gliomas.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No
