Pilot Study of Reduced Intensity Haematopoietic Stem Cell Transplantation in Patients With Poor Risk Myelodysplastic Syndrome and Acute Myeloid Leukaemia Utilising Conditioning With Fludarabine, Busulphan and Thymoglobulin

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
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.
