Summary
Malignant infantile osteopetrosis (MIOP) is a rare fatal genetic disorder that is
characterized by the bone's inability to regulate remodeling. The only curative therapy is
hematopoietic stem cell transplantation. Stem cells provided from an HLA identical matched
sibling donor is the standard of care, but not feasible for the majority of patients. In
addition, due to the potentially rapid progression of this disease, the time to identify a
suitable HLA matched unrelated donor is not optimal. Therefore this study is designed to test
the hypothesis that children with osteopetrosis can properly engraft hematopoietic stem cells
that are donated from a partially matched parental donor, or "haploidentical" stem cell donor
that are processed on the investigational device, CliniMACS selection system.
