Study Summary

The purpose of this study is to find out whether siplizumab is safe and effective for patients with SCD undergoing an allogeneic transplant and to prevent development of Graft versus Host Disease (GVHD) and graft failure. The main goals of this study are : * To determine if acute GVHD occurs and how severe the acute GVHD is in subjects receiving the study drug * To determine if graft failure occurs in subjects receiving the study drugs In this study, participants will receive 5 infusions of the study drug, siplizumab, while getting a stem cell transplant for SCD. Before siplizumab infusion, participants will be given medications to reduce the risks of allergic reaction to the drug.

Primary Outcome

Failure rate is a safety endpoint. Failure rate is defined as: graft failure (Primary Graft Rejection: Primary graft rejection is defined as the absence of donor cells (% donor cells \< 5%) assessed by bone marrow or peripheral blood chimerism assays by Day 42. Late Graft Rejection: The absence (\<5%) of donor hematopoietic cells in peripheral blood or bone marrow beyond Day 42 in a patient who had initial evidence of hematopoietic recovery with \> 20% donor cells will be considered a late graft
