Summary

The goal of this study is to develop a novel approach to hematopoietic stem cell transplantation for children with Severe Combined Immunodeficiency Disease (SCID) that eliminates the use of toxic chemotherapy conditioning and maximizes the likelihood of T and B cell immune reconstitution. Rather than classic chemotherapeutic agents, the investigators will utilize a targeted stem cell mobilizer, plerixafor, in combination with alemtuzumab, a monoclonal antibody. Correlative scientific questions will include: 1) efficacy and characteristics of host stem cell mobilization; and 2) alemtuzumab pharmacokinetics in very young children.
