A Phase II Study of Intensity Modulated Total Marrow Irradiation (IM-TMI) in Addition to Fludarabine/Busulfan Conditioning for Allogeneic Transplantation in High Risk AML and Myelodysplastic Syndromes
The study is a Phase II clinical trial. Patients will receive intensity modulated total marrow irradiation (TMI) at a dose of 9 Gy with standard myeloablative fludarabine/ i.v. targeted busulfan (FluBu) conditioning prior to allogeneic hematopoietic stem cell transplant (HSCT).

Conditions
- Acute Myeloid Leukemia
- Myelodysplastic Syndromes
Interventions
- Fludarabine
- Busulfan
- ATG
- Total Marrow Irradiation
- Stem Cell Product Infusion
- Tacrolimus
- Methotrexate
Primary outcomes
- Relapse free survival of approximately 30% in high-risk patients conditioned with the Fludarabine/ Busulfan regimen — Up to 1 year
Using a Simon 2 stage optimal design with α of 0.05 and power of 0.8, 15 patients will be enrolled in the first stage. If greater than 5 patients survive to 1 year without relapse the study will continue into stage 2. Recruitment will then continue to a total of 46 patients. In this expanded cohort, if a total of 18 or more patients survive to 1 year without relapse, the treatment will be judged efficacious and worthy of further study.
