RATIONALE: Monoclonal antibodies, such as alemtuzumab, can find cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Giving chemotherapy drugs, such as busulfan and cyclophosphamide, before a donor stem cell transplant helps stop the growth of cancer 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 tacrolimus and methotrexate after the transplant may stop this from happening.
PURPOSE: This phase I/II trial is studying the best dose of alemtuzumab when given together with busulfan and cyclophosphamide followed by a donor stem cell transplant and to see how well it works in treating patients with hematologic cancer.
|Condition or disease||Intervention/treatment||Phase|
|Graft Versus Host Disease Leukemia Myelodysplastic Syndromes Myelodysplastic/Myeloproliferative Diseases||Biological: alemtuzumab Drug: busulfan Drug: cyclophosphamide Drug: methotrexate Drug: tacrolimus Procedure: allogeneic hematopoietic stem cell transplantation Procedure: peripheral blood stem cell transplantation||Phase 1 Phase 2|
- Identify the lowest dose of alemtuzumab that is associated with day 180 transplant-related mortality ≤ 45%.
- Determine the incidence of life-threatening infection in patients receiving this treatment.
- Determine the incidence of grades III-IV acute graft-vs-host disease (GVHD) in patients receiving this treatment.
- Determine the survival at 1 year in patients receiving this treatment.
- Determine the incidence of disease relapse at 1 year in patients receiving this treatment.
- Determine the incidence of extensive chronic GVHD at 1 year in patients receiving this treatment.
- Determine the incidence of graft failure at day 100 in patients receiving this treatment.
- Chemotherapy: Patients receive alemtuzumab IV over 2 hours on days -10 to -6, busulfan IV over 3 hours on days -7 to -4, and cyclophosphamide IV on days -3 and -2.
- Peripheral blood stem cell (PBSC) transplantation: Patients undergo allogeneic filgrastim (G-CSF)-mobilized PBSC transplantation on day 0.
- Graft-vs-host disease prophylaxis: Patients receive tacrolimus IV continuously or orally twice daily on days -1 to 50 and methotrexate IV on days 1, 3, 6, and 11.
After completion of study therapy, patients are followed periodically.
