Overview
Brief Summary
The purpose of this study is to determine the safety and feasibility of conditioning with fludarabine, busulphan and thymoglobuline in patients with myelodysplastic syndrome (MDS), myelodysplastic/myeloproliferative disorders (MDS/MPD) or acute myeloid leukaemia (AML) undergoing haematopoietic stem cell allograft with granulocyte colony-stimulating factor (G-CSF)-mobilised peripheral blood stem cells (PBSC) (or bone marrow) from HLA compatible sibling donors.

Eligibility Criteria
Inclusion Criteria
- •Patient Selection
- •Availability of a HLA compatible sibling donor
- •Age \>18 years
- •Myelodysplastic Syndromes with IPSS Intermediate-2 or High.
- •Poor risk acute myeloid leukaemia, de novo or transformed from MDS
- •Ineligibility for standard conditioning allograft due to age or co-existing morbidities
- •Donor selection
- •Related donors compatible for HLA-A, B, C, DRB1 and DQB1 by molecular typing.
Exclusion Criteria
- •Patient selection
- •Cardiac insufficiency requiring treatment or symptomatic coronary artery disease.
- •Hepatic disease, with AST \> 2 times normal.
- •Severe hypoxaemia, pO2 \< 70 mm Hg, with decreased DLCO \< 70% of predicted; or mild hypoxemia, pO2 \< 80 mm Hg with severely decreased DLCO \< 60% of predicted.
- •Impaired renal function (creatinine \> 2 times upper limit of normal or creatinine clearance \< 50% for age, gender, weight).
- •Patients who have received previous treatment with Thymoglobuline
- •HIV-positive patients.
- •Female patients who are pregnant or breast feeding due to risks to foetus from conditioning regimen and potential risks to nursing infants.
- •Life expectancy severely limited by diseases other than MDS or MPD.
- •Serious concurrent untreated infection
