Bone Marrow Transplant
|Closed||Aplastic Anemia; Bone Marrow and Hematopoietic Stem Cell Transplant (BMT and HSCT); Non-malignant Condition||Phase I/II||
This is an unrelated donor transplantation study for patients up to age 65 with severe aplastic anemia.The purpose of this study is to determine what dose of cyclophosphamide should be used, along with other medications before transplantation, to improve the safety and effectiveness of transplantation.
The chemotherapy and irradiation given just before a transplant is called the conditioning regimen. Participants in this study will receive a conditioning regimen consisting of fludarabine, cyclophosphamide, and antithymocyte globulin (ATG), as well as low-dose total body irradiation.
Different groups of participants will receive different amounts of cyclophosphamide, of which they will be informed.
Study participants will then receive a bone marrow transplant using cells from an unrelated donor.
Most of the care will be given at the Seattle Cancer Care Alliance (SCCA) outpatient clinic. During the transplant and the initial recovery period, and if needed at different time points after the transplant, participants will be admitted to the UW Medical Center hospital.
Participants will be asked to come to the SCCA clinic on a regular basis for exams and blood tests for about 3 months after the transplant. Participants will be followed by their personal physicians for up to 2 years.
