Bone Marrow Transplant
|Recruiting||Chronic Myeloproliferative Disorders
This non-myeloablative, stem cell transplant study is for adults who have chronic myelomonocytic leukemia (CMML), or previously untreated myelodysplastic syndrome (MDS) or myeloproliferative disorders (MPD). The participants in this study have either an HLA-matched, related donor or an HLA-matched, unrelated donor available to donate the stem cells needed for the transplant.
Non-myeloablative stem cell transplants use lower doses of chemotherapy and total body irradiation (TBI) than conventional stem cell transplants. In previous studies, participants with MDS, CMML and MPD were shown to be at an increased risk of rejecting their donor's stem cells, and of having their disease relapse soon after transplantation. It is unknown what dose of TBI will be effective enough to prevent graft rejection and disease progression. The purpose of this study is to find a safe and effective dose of TBI (given before the transplant) to prevent graft rejection and/or disease relapse after the transplant. Participants in non-myeloablative transplants also receive drugs to suppress their immune systems. We will also evaluate whether or not these drugs, called cyclosporine and mycophenolate mofetil (MMF), can help prevent graft-versus-host disease (GVHD). GVHD is a serious side effect that can occur after a transplant. It is an inflammatory disease that occurs when the "new" cells (the donor's cells) react against the participant's cells.
We plan to treat the participant at the Seattle Cancer Care Alliance outpatient clinic. The study treatment and initial follow-up will last about three and a half months. If hospitalization is needed, the participant will be admitted to the University of Washington Medical Center.
Before the transplant, participants will receive the drugs fludarabine and cyclosporine. On the day of the transplant, the participant will receive low-dose, total body irradiation (TBI). The participant will also start taking a drug called mycophenalate mofetil (MMF). The participant will be monitored closely following the transplant. We will continue standard follow-up for five years. We would like to continue to keep track of the participant's medical condition for his or her lifetime to look at the long-term effects of the study.
