Patients Will Undergo Donor/Recipient Bone Marrow
All patients will undergo haploidentical, allogeneic hematopoietic cell transplantation. Conditioning will consist of fludarabine, melphalan, and thiotepa. Graft versus host disease prophylaxis will be with post-transplant cyclophosphamide in addition to standard tacrolimus and mycophenolate mofetil. Donors will undergo HLA and KIR geno- and allotyping to determine the best donor. melphalan: melphalan (140 mg/m2 IV on day -7) fludarabine: fludarabine (40 mg/m2/d on days -5 through -2) thiotepa: thiotepa (5 mg/kg IV on day -67) Cyclophosphamide: cyclophosphamide (50 mg/kg IV on day +3 and +4) Mesna Mycophenolate Mofetil: (15 mg/kg PO/IV TID) Filgrastim Tacrolimus
