Detailed Description:

In this study, we are seeking to target the leukemia microenvironment to overcome disease resistance. We hypothesize that by disrupting the interaction of leukemic blasts with the bone marrow microenvironment, we may sensitize leukemic blasts to the effects of cytotoxic chemotherapy. In this study, we seek to maximize blockage of the SDF-1/CXCR4 axis through the following:

  1. Addition of G-CSF, which down regulates SDF-1 expression and acts synergistically with plerixafor in stem cell mobilization
  2. Intravenous instead of subcutaneous dosing of plerixafor to improve kinetics of administration.
  3. Dose escalation of plerixafor and twice daily dosing to maintain maximum CXCR4 blockade.

  4. Adequate organ function defined as:

    • Calculated creatinine clearance ≥ 50 ml/min
    • AST, ALT, total bilirubin ≤ 2 x ULN except when in the opinion of treating physician is due to direct involvement of leukemia (eg. hepatic infiltration or biliary obstruction due to leukemia)
    • Left ventricular ejection fraction of ≥ 40% by MUGA scan or echocardiogram
  5. Are surgically or biologically sterile or willing to practice acceptable birth control, as follows:

    • Females of child bearing potential must agree to abstain from sexual activity or to use a medically approved contraceptive measure/regimen during and for 3 months after the treatment period. Women of child bearing potential must have a negative serum or urine pregnancy test at the time of enrollment. Acceptable methods of birth control include oral contraceptive, intrauterine device (IUD), transdermal/implanted or injected contraceptives and abstinence.
    • Males must agree to abstain from sexual activity or agree to utilize a medically approved contraception method during and for 3 months after the treatment period

Exclusion Criteria:

  1. Acute promyelocytic leukemia (AML with t(15;17)(q22;q11) and variants)
  2. Peripheral blood blast count ≥ 20 x 103 /mm3
  3. Active CNS involvement with leukemia
  4. Previous treatment with MEC or other regimen containing both mitoxantrone and etoposide
  5. Pregnant or nursing
  6. Received any other investigational agent or cytotoxic chemotherapy (excluding hydroxyurea) within the preceding 2 weeks
  7. Received colony stimulating factors filgrastim or sargramostim within 1 week or pegfilgrastim within 2 weeks of study
  8. Severe concurrent illness that would limit compliance with study requirements
