Eligibility Criteria  ICMJE

Age, Unit Cell Dose and HLA Match Criteria

  • Subjects must be ≤55 years of age
  • Subjects must weigh >11 kg
  • Subjects must have a partially HLA matched UCB unit with a pre-cryopreserved TNC dose >1.0 x 107 per kilogram recipient weight. HLA matching is initially based on a minimum of 5 of 8 HLA alleles at high resolution A, B, C, DRB1 typing; searches will be performed according to the current Magenta Cord Blood Search Algorithm.

Eligible Diseases:

  • Acute myelogenous leukemia (AML) in morphological complete remission with:

    • Minimal residual disease (MRD) by flow cytometry, or
    • Intermediate to high risk leukemia in first (CR1) based on institutional criteria, eg. not favorable risk AML which is defined as having one of the following:

Females of childbearing potential must have a blood test or urine study within 14 days prior to study enrollment to rule out pregnancy.
