Donor-specific Allogeneic Hematopoietic Cell Transplantation for Acute Lymphoblastic Leukemia (ALL) (AHCTALL)
- To evaluate the efficacy of allogeneic hematopoietic cell transplantation (HCT) in patients with acute lymphoblastic leukemia (ALL) in the first or second complete remission (CR). The efficacy of the treatment will be measured in terms of the frequency of relapse and duration of remission (the primary endpoints).
- The secondary end points of the study include; engraftment, donor chimerism, secondary graft failure, acute and chronic graft-versus-host disease (GVHD), immune recovery, infections, transplantation-related mortality, leukemia free survival, and overall survival.

alloHCT arm: For HLA-matched sibling HCT, if a patient is 55 years old or less and without co-morbidity, the patient will receive Bu-Cy conditioning therapy and be transplanted with bone marrow cells. Patients who are older than 55 years or with co-morbidity will receive Bu-Flu-ATG conditioning and be transplanted with mobilized peripheral blood hematopoietic cells. For HLA-matched unrelated donor or HLA-mismatched familial donor HCT, the patient will receive Bu-Flu-ATG conditioning and well be transplanted with mobilized peripheral blood hematopoietic cells.
[ alloHCT arm ] Bu-Cy conditioning; Busulfan (Bu) 3.2 mg/kg*/day iv daily on days -7 and -4. Cyclophosphamide (Cy) 60 mg/kg* in D5W 200 mL iv over 1-2 hours daily on days -3 and -2.
BuFluATG conditioning; Bu 3.2 mg/kg*/day iv daily on days -7 and -6. Fludarabine (Flu) 30 mg/m2/day in D5W 100 ml iv over 30 minutes starting at 4 pm daily on days -7, -6, -5, -4, -3, and -2.
Anti-thymocyte globulin (ATG, Thymoglobulin, Genzyme Transplant, Cambridge, MA, USA) 1.5 mg/kg/day (for HLA-matched sibling HCT) or 3.0 mg/kg/day (for HLA-matched unrelated donor HCT or HLA-mismatched familial donor HCT) in N/S 500-800 ml (less than 4 mg/ml) iv over 4 hours starting at 8 am daily on days , -3, -2 and -1.
