Clinical Trial Summary

To evaluate the efficacy of the conditioning regimen with cyclophosphamide, fludarabine, and antithymocyte globulin (CyFluATG) for allogeneic hematopoietic cell transplantation (HCT) in patients with lower risk myelodysplastic syndrome (MDS). The efficacy of the treatment will be measured in terms of engraftment and non-relapse mortality (NRM).


Clinical Trial Description

- This is a prospective, phase 2 extension study - Conditioning regimen A. Cyclophosphamide 50 mg/kg/day i.v. daily on days -3 and -2 (for 2 days) B. Fludarabine 30 mg/m2/day i.v. daily on days -7to -2 (for 6 days) C. Antithymocyte globulin (Thymoglobulin) 1.5 mg/kg/day (for HLA-matched sibling donor HCT) or 3.0 mg/kg/day (for other alternative donor HCT) i.v. daily on days -3 to -1 (for 3 days) D. Methylprednisolone 2 mg/kg i.v. daily on days -4 to -1 (for 4 days) - Harvest and infusion of donor hematopoietic cells A. Harvested peripheral blood mononuclear cells of donors via leukapheresis will be infused to recipients on day 0. Additional infusion on day 1 can be made based on the judgement of attending physician. - GVHD prophylaxis A. Cyclosporine: 1.5 mg/kg i.v. every 12 hours beginning on day -1 and changed to oral dosing (with twice the i.v. dose) when oral intake is possible. B. Methotrexate: 15 mg/m2 i.v. on day 1, and 10 mg/m2 i.v. on days 3 and 6. ;
