Study Details

The purpose of this study is to evaluate what effect, if any, mismatched unrelated volunteer donor and/or haploidentical related donor stem cell transplant may have on severe sickle cell disease and other transfusion dependent anemias. By using mismatched unrelated volunteer donor and/or haploidentical related donor stem cells, this study will increase the number of patients who can undergo a stem cell transplant for their specified disease. Additionally, using a T-cell depleted approach should reduce the incidence of graft-versus-host disease which would otherwise be increased in a mismatched transplant setting.

Arms

  • Experimental: Hematopoietic Stem Cell Transplantation
    All patients will receive a CD3+/CD19+ depleted stem cell transplant. In this study, the investigators will use HLA mismatched unrelated or haploidentical related donor peripheral blood stem cells. Prior to transplantation, the marrow (90-95%) will be negatively selected for CD3/CD19 using the ClinicMACs® depletion device. The remaining (5-10%) will undergo CD45+RA+ depletion and be frozen for future use as an immune boost. Subjects will undergo hematopoietic stem cell transplant utilizing CD3+/CD19+ depleted cells following conditioning therapy.

Primary Outcome Measure

Graft rejection [ Time Frame: Day -30 through study completion, an average of 2 years ]
