Official title
Peripheral Blood Mobilized Hematopoietic Precursor Cell Transplantation Followed by T Cell Add-Back for Hematological Malignancies - Effect of Irradiated Donor Lymphocytes on Chimerism
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Bone marrow transplantation (BMT) is a risky procedure. If doctors could reduce the complications, BMT would be safer to use for a wider range of conditions. The purposes of this study are * to prevent graft rejection by increasing the amount of immunosuppression and by giving some lymphocytes from the donor before transplant; * to prevent graft-versus-host disease (GVHD) by transplanting T-cell depleted stem cells; * to improve the immune effect against residual leukemia by the add-back of donor lymphocytes before transplant and six or more weeks after transplant. Beyond the standard transplant protocol, study participants will undergo additional procedures. First, along with total body irradiation, patients will receive two drugs (a high dose of cyclophosphamide and fludarabine) to suppress immunity and prevent rejection of the transplant. Second, four days before the transplant, patients will be given donor lymphocytes that have been irradiated to make them incapable of causing GVHD. On the day of the transplant, patients will receive an infusion of T-cell depleted bone marrow stem cells. Finally, patients will receive two doses of add-back donor T-cells (45 and 100 days post transplant) and the immunosuppressive drug cyclosporine starting on day 44 until about six months after transplant. Study participants must be between the ages of 10 and 56 and have a family member who is a suitable stem cell donor match.
