CBA Versus FBA Conditioning Followed by Allogeneic HSCT in Treatment of High Risk and Refractory AML
Aim: To evaluated if cladribine based conditioning (CBA) could decrease relapse after HLA matched HSCT in high risk and refractory AML patients as compared with fludarabine based conditioning regimen(FBA).
Study design: open-labed, prospective, multicenter, randomized control study Number of subjects: 60 each group
Treatment:
CBA group: CBA as HSCT conditioning which including cladribine 5mg/m2 day -6 to day -2 , busulfan(iv) 3.2mg/kg day-6 to day -3 and cytarabine 2g/m2 day-6 to day -2.
FBA group: FBA as HSCT conditioning which including fludarabine 30mg/m2 day -6 to day -2, busulfan(iv) 3.2mg/kg day-6 to day -3 and cytarabine 2g/m2 day-6 to day -2.

Detailed Description
Relapse is still the main reason of death for patients with acute myeloid leukemia (AML) undergoing allogeneic hematopoietic stem cell transplantation (HSCT), especially for those with high risk and refractory disease. Cladribine and fludarabine are both purine analogs used in treatment of AML. Two studies by the Polish Adult Leukemia Group (PALG) demonstrated that the addition of cladribine to DA (DAC) was associated with an increased complete remission (CR) rate and prolonged overall survival (OS) in the general AML population, with the most prominent effect in patients with unfavorable cytogenetics. Therefore we presume cladribine may more effective in eliminating leukemic cells so that reduce relapse after HSCT.
Eligible patients in this study should between 18 to 60 years old with confirmed AML and fulfilled at least one criteria defining high risk or refractory disease.Patients must have HLA 9/10 or 10/10 matched sibling or unrelated donor. Patients will be excluded if they present any contraindication for HSCT, including respiratory failure, heart failure, liver or kidney function failure et al.
To evaluate if cladribine based conditioning (CBA) could decrease relapse after HLA matched HSCT in high risk and refractory AML patients as compared with fludarabine based conditioning regimen(FBA), 120 eligible patients will be randomized to two groups, the CBA group and the FBA group. Patients in the CBA group receive conditioning including cladribine 5mg/m2 day -6 to day -2 , busulfan(iv) 3.2mg/kg day-6 to day -3 and cytarabine 2g/m2 day-6 to day -2. While patients in the FBA group receive conditioning including fludarabine 30mg/m2 day -6 to day -2 , busulfan(iv) 3.2mg/kg day-6 to day -3 and cytarabine 2g/m2 day-6 to day -2. Graft versus host disease(GVHD) prophylactic regimen include cyclosporine A and short term MTX, ATG 6mg/kg is additionally administered to patients with unrelated donors.
Patients will be followed up for 2 years and the primary end point is the cumulative relapse rate at 2 years. The second end points of the study include the overall survival, disease free survival and non-relapse mortality at 2 years.
