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.
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.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.
