Clofarabine and High-Dose Melphalan Followed by Donor Stem Cell Transplant in Patients With Acute Myeloid Leukemia, Acute Lymphocytic Leukemia, or Myelodysplastic Syndromes

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

Summary

RATIONALE: Giving chemotherapy, such as clofarabine and melphalan, before a donor stem cell transplant helps stop the growth of cancer or abnormal cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient, they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening.

PURPOSE: This phase I trial is studying the side effects and best dose of clofarabine when given together with high-dose melphalan followed by a donor stem cell transplant in treating patients with acute myeloid leukemia, acute lymphocytic leukemia, or myelodysplastic syndromes.
