This is a prospective single center phase II study of a reduced intensity conditioning based hematopoietic cell transplant for patients with sickle cell disease. In this study, patients with SCD who would be expected to benefit from an allogeneic HCT will receive an unmanipulated peripheral blood derived hematopoietic stem and progenitor cell (HSPC) graft from either an MSD or HAPLO donor after a reduced intensity conditioning regimen comprising of alemtuzumab, thiotepa and low dose total body irradiation. All patients will receive a pre-conditioning phase comprising of hydroxyurea and azathioprine to reduce the risk of graft rejection. GVHD prophylaxis will consist of sirolimus. Patients on the HAPLO arm will also receive two doses of post-transplant cyclophosphamide. All patients will receive regularly scheduled low dose donor lymphocyte infusions till donor lymphocyte chimerism reaches at least 90% donor. The main objective of this study is to improve graft function and immune reconstitution after a reduced intensity conditioning based transplant.
