Brief Summary

Hematopoietic stem cell transplantation (HCT)-associated thrombotic microangiopathy (TMA) is an understudied complication of HCT that significantly affects transplant related morbidity and mortality. The investigators hypothesize that early intervention with complement blocker eculizumab will double survival in HCT recipients with high risk TMA, as compared to historical untreated controls. An optimal eculizumab dosing schedule can be determined for this population through eculizumab pharmacokinetic/pharmacodynamic (PK/PD) testing.
