A pilot study of reduced toxicity conditioning with BU, fludarabine and alemtuzumab before the allogeneic hematopoietic SCT in children and adolescents

We report the results of a pilot study of a BU–fludarabine–alemtuzumab (BFA)-reduced toxicity conditioning (RTC) followed by allogeneic hematopoietic SCT (AlloHSCT) in 12 children and adolescents (

Stem cell sources were: two unrelated cord blood, one unrelated BM, two related and seven unrelated PBSC. Positive CD34 selection was performed in five unrelated PBSC grafts. RCT was carried out with BFA, and GVHD prophylaxis was FK506 and mycophenolate mofetil. The median time for neutrophil and platelet engraftment was 16 and 31 days, respectively. The P of developing ⩾grade II, ⩾grade III aGVHD and cGVHD was 41.6, 25 and 9%, respectively. Only 1 out of 12 developed ⩾grade III toxicity. There was one primary and no secondary graft failure. Mixed donor chimerism on day 100 and 1 year was median 99 and 96%, respectively; ⩾90% of recipients achieved ⩾80% donor chimerism.
