Primary Outcome Measures:
  • Treatment-related mortality [ Time Frame: 30 days after start of treatment ]
  • Delayed hematologic recovery [ Time Frame: Day 46 of treatment ]
    Defined as neutrophil recovery (ANC > 1,000/mm3) > 42 days after the start of chemotherapy in the absence of persistent leukemia

Secondary Outcome Measures:
  • Complete remission rate cytogenetic complete remission [ Time Frame: 42 days ]
  • Overall survival [ Time Frame: 2 years ]
    Every 6 months

  • Disease-free survival [ Time Frame: 2 years ]
    Every 6 months

  • Remission duration [ Time Frame: 2 years ]
    Every 6 months

  • Frequency and severity of adverse events [ Time Frame: 30 days post treatment ]
  • Interaction of pretreatment disease and patient characteristics on clinical outcomes [ Time Frame: Baseline ]
    Morphology, cytogenetics, immunophenotype, WBC, and performance status

Enrollment: 13
Study Start Date: July 2011
Study Completion Date: November 2015
Primary Completion Date: October 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: G-CSF + Ifosfamide + Etoposide + Dexamethasone + Mesna

G-CSF = 10 mcg/kg/d SQ starting on day 1 and continuing until ANC >=1000/mcL x 2 days

Ifosfamide = 3330 mg/m2/d CIVI over 24 hours on Days 4-6

Etoposide = 150 mg/m2 IV over 2 hours BID on Days 4-6

Dexamethasone = 5 mg/m2 PO or IV BID on Days 4-10

Mesna = 2660 mg/m2/d continuous IV infusion over 24 hours on Days 4-6. 2000 mg/m2 continuous IV infusion over 12 hours on Day 7 to be started immediately after completion of ifosfamide.

Detailed Description:
In this study, we will combine G-CSF as priming prior to and during the administration of salvage chemotherapy regimen in ALL. Abundant data suggests that leukemic cells receive key growth and survival signals from the bone marrow microenvironment. Our preclinical data show that 4-5 days of G-CSF treatment is associated with a loss of osteoblasts and decreases expression of key chemokine/ cytokines which support lymphocyte development. The investigators hypothesize that G-CSF will disrupt the protective effects of the bone marrow microenvironment and augment the effect of chemotherapy in adults with ALL. This is a pilot study of G-CSF priming in adult patients with relapsed or refractory ALL to determine the feasibility and to characterize the effect of G-CSF treatment on the marrow microenvironment.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Acute lymphoblastic leukemia diagnosed according to WHO criteria (>25% lymphoblasts in BM) which is relapsed or refractory to therapy. Patients with t(9;22) must be refractory to BCR-ABL tyrosine kinase inhibitors.
  • Age ≥ 18 years
  • ECOG performance status ≤ 3.
  • Adequate organ function defined as:

    • Calculated creatinine clearance ≥ 50 ml/min
    • AST, ALT, total bilirubin ≤ 2 x institutional ULN except when in the opinion of treating physician elevated levels are due to direct involvement of leukemia (eg. hepatic infiltration or biliary obstruction due to leukemia)
  • Women of childbearing potential and sexually active males must be willing and able to use effective contraception while on study.
  • Able to provide signed informed consent prior to registration on study.

Exclusion Criteria:

  • Previous salvage chemotherapy with ifosfamide and etoposide
  • Pregnant or nursing
  • Received any other investigational agent or cytotoxic chemotherapy within the preceding 2 weeks
  • Received colony stimulating factors filgrastim or sargramostim within 1 week or pegfilgrastim within 2 weeks of study
  • Severe concurrent illness that would limit compliance with study requirements
