Arms Assigned Interventions
Experimental: FBATG
Haematopoietic stem cell transplantation utilising conditioning with Fludarabine, Busulphan and Thymoglobuline
Drug: Fludarabine
Fludarabine 30mg/m2 intravenously daily on days -9 to -5 inclusive of stem cell infusion.
Drug: Busulphan
Busulphan 0.8mg/kg intravenously 6 hourly on days -4 and -3 of stem cell infusion.
Drug: Thymoglobuline (Anti-thymocyte globulin [rabbit]) - Genzyme
Thymoglobuline will be given intravenously over a minimum of 6 hours for the first two doses and 4 hours for the subsequent doses. Acute side effects of ATG appear to be reduced if a very low dose is given for the first injection. Thymoglobuline 0.5mg/kg iv on day -4, 1.5mg/kg/day on day -3; and 2mg/kg/day iv on day -2 to -1 inclusive.
Procedure: Haematopoietic stem cell infusion
The source of stem cells will be PBSC wherever possible. Patients whose donors decline or are unable to donate PBSC will be transplanted with marrow cells.
