17-N-Allylamino-17-Demethoxygeldanamycin in Treating Patients With Chronic Phase Chronic Myelogenous Leukemia That Did Not Respond to Imatinib Mesylate

• Status: Completed
• Trial end date: 2006-10-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Drugs used in chemotherapy, such as 17-N-allylamino-17-demethoxygeldanamycin, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. It may also stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

PURPOSE: This phase I trial is studying the side effects and best dose of 17-N-allylamino-17-demethoxygeldanamycin in treating patients with chronic phase chronic myelogenous leukemia that did not respond to imatinib mesylate.

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

Details

• Lead Sponsor: Jonsson Comprehensive Cancer Center
• Collaborator: National Cancer Institute (NCI)
