Sunitinib in Treating Patients With Relapsed or Refractory Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma

• Status: Completed
• Trial end date: 2011-01-01
• Target enrollment: 0
• Participant gender: All

Summary

This phase II trial is studying how well sunitinib works in treating patients with relapsed or refractory chronic lymphocytic leukemia or small lymphocytic lymphoma. Sunitinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: National Cancer Institute (NCI)
• Treatments: Sunitinib
