Inclusion Criteria:

  • Diagnosis of AML defined according to the WHO classification
  • Age ≥ 18 years
  • New presentation or relapsed AML
  • Patients must be able to give written informed consent
  • Failure to enter complete morphological remission (>5% bone marrow AML cells) or persistence of cytogenetic abnormality following intensive combination chemotherapy At day+100 post-transplant
  • HIV negative
  • No GvHD
  • No continuing use of immunosuppressive drugs
  • Absence of active systemic fungal or viral infection including HTLV-1, hepatitis B or C.
  • Adequate renal and liver function confirmed by: creatinine clearance >30mls/min; bilirubin <3.0 x upper limit of normal; AST <3.0 x upper limit of normal; prothrombin time <2.0 x upper limit of normal.

Performance status of 1 or less by ECOG criteria or >80% by the Karnovsky score

  • Patient must provide written informed consent and be willing to comply for the duration of the study.
  • Life expectancy >36 weeks
  • Women of childbearing potential (WCBP) must have a negative serum or urine pregnancy test within 10 - 14 days and again within 24 hours of starting the study. In addition, sexually active WCBP must agree continued abstinence from heterosexual intercourse or to use adequate contraceptive methods starting 4 weeks prior to the initiation of therapy (see appendix G for pregnancy testing and birth control guidelines while on study). WCBP must agree to have pregnancy tests every 3 weeks while on study drug (every 14 days for women with irregular cycles) and 4 weeks after the last dose of study drug. Men must also agree to use a condom if their partner is of child bearing potential, even if they have had a successful vasectomy.

Exclusion Criteria:

  • Age < 18 years
  • Patients not fit for intensive chemotherapy
  • Complete morphological and cytogenetic remission following intensive combination chemotherapy
  • Absence of HLA compatible donor
  • HIV positive
  • Evidence of graft versus host disease at day+100 post transplant
  • Evidence of relapse of leukaemia (≥5% bone marrow blasts)
  • Concurrent use of other forms of anti-leukaemic therapy
  • Other malignancy with the exception of carcinoma in situ.
  • Significant history of heart disease (unstable angina, myocardial within the past six months, congestive cardiac failure requiring daily treatment)
  • Evidence of active lung disease determined by chest x-ray and absence of chronic lung disease (FEV1<60% predicted, Vital capacity <60%, Tlco<50%)
