Combination Chemotherapy Followed By Donor Umbilical Cord Blood Transplant in Treating Infants With High-Risk Acute Leukemia or Myelodysplastic Syndromes
Hematopoietic Cell Transplantation in the Treatment of Infant Leukemia Using Double Umbilical Cord Transplantation

RATIONALE: Giving chemotherapy, such as busulfan, fludarabine, and melphalan, before a donor umbilical cord blood stem cell transplant helps stop the growth of abnormal or cancer cells and prepares the patient's bone marrow for the stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil may stop this from happening.

PURPOSE: This phase II trial is studying how well combination chemotherapy followed by a donor umbilical cord blood transplant works in treating infants with high-risk acute leukemia or myelodysplastic syndromes.

OBJECTIVES:

Primary

  • Determine the incidence of engraftment, defined as achieving donor-derived neutrophil count > 500/mm³ by day 42, in infants with high-risk acute myeloid leukemia, acute lymphoblastic leukemia, or myelodysplastic syndromes treated with a non-irradiation containing myeloablative conditioning regimen comprising busulfan, fludarabine, and melphalan followed by double umbilical cord blood transplantation (UCBT) with two partially HLA-matched units.

Secondary Objectives

  • Determine the incidence of transplant-related mortality (TRM) at 6 months after UCBT
  • Evaluate pattern of chimerism after double UCBT
  • Determine the incidence of platelet engraftment at 1 year after UCBT
  • Determine the incidence of acute graft-versus-host disease (GVHD) grade II-IV and grade III-IV at day 100 after UCBT
  • Evaluate the developmental outcome after UCBT

Transplant Related Objectives

  • Determine the incidence of chronic GVHD at 1 year after UCBT
  • Determine the survival and disease free survival at 1 and 2 years after UCBT
  • Determine the incidence relapse at 1 and 2 years after UCBT

Primary Purpose: Treatment
  • Leukemia
  • Myelodysplastic Syndromes
  • Biological: filgrastim
    All patients will receive G-CSF 5 mcg/kg/day intravenous (IV) (dose rounded to vial size) based on the actual body weight IV beginning on day +1 after umbilical cord blood (UCB) infusion. G-CSF will be administered daily until the absolute neutrophil count (ANC) exceeds 2.5 x 10^9/L for three consecutive days and then discontinued. If the ANC decreases to <1.0 x 10^9/L, G-CSF will be reinstituted.
    Other Name: G-CSF
  • Drug: busulfan
    Administered 1.1 mg/kg if <12 kg intravenous (IV) every 6 hours (0.8 mg/kg if >12 kg IV every 6 hours on Days -8 through -5.
    Other Name: Busulfex
  • Drug: cyclosporine
    Patients will receive cyclosporine (CSA) therapy beginning on day -3 maintaining a level of >200 ng/mL. For children < 40 kg the initial dose will be 2.5 mg/kg intravenous (IV) over 2 hours every 8 hours.
    Other Name: CSA
  • Drug: fludarabine phosphate
    Administered 25 mg/m^2 intravenous (IV) over 60 minutes on Days -4 through -2.
    Other Name: Fludara
  • Drug: melphalan
    Administered 60 mg/m^2 intravenous (IV) over 30 minutes on Days -4 through -2.
    Other Name: Alkeran
  • Drug: mycophenolate mofetil
    All patients will begin mycophenolate mofetil (MMF) on day -3. Patients <45 kilograms will receive MMF at the dose of 15 mg/kg/dose every 8 hours (max dose 1gm/dose) orally or intravenously (PO or IV).
    Other Name: MMF
  • Procedure: umbilical cord blood transplantation
    The product is infused via IV drip directly into the central line without a needle, pump or filter on Day 0.
  • Experimental: Double Unit UCB Transplantation
    Patients that receive 2 units of umbilical cord blood transplantation (UCBT).

Inclusion Criteria:

  • Patients on this trial will receive two partially HLA matched umbilical cord blood (UCB) units, if available (treatment arm 1). If two units are not available, then single UCB unit transplantation will be allowed (on treatment arm 2).
  • UCB units will be selected according to the University Of Minnesota UCB Graft Selection Algorithm. The unrelated cord blood donor(s) must be 4-6/6 HLA-A, B, DRB1 matched with the recipient (HLA matching using molecular techniques: A and B to antigen level resolution and DR to allele level resolution).
  • Patients aged ≤ 2 years at diagnosis (not age of transplant) with hematological malignancy as detailed below:

    • Acute myeloid leukemia: high risk CR1 as evidenced by:

      • High risk cytogenetics t(4;11) or other MLL rearrangements; chromosome 5, 7, or 19 abnormalities; complex karyotype (>5 distinct changes); ≥ 2 cycles to obtain complete response (CR); CR2 or higher; Preceding myelodysplastic syndrome (MDS); All patients must be in CR or early relapse (i.e., <15% blasts in BM).
      • Acute lymphocytic leukemia: high risk CR1 as evidenced by: High-risk cytogenetic: t(4;11) or other MLL rearrangements; hypodiploid; t(9;22); >1 cycle to obtain CR; CR2 or higher; All patients must be in CR as defined by hematological recovery, AND <5% blasts by light microscopy within the bone marrow with a cellularity of ≥15%.
    • Myelodysplasia (MDS) IPSS Int-2 or High risk (i.e. RAEB, RAEBt) or refractory anemia with severe pancytopenia or high risk cytogenetics. Blasts must be < 10% by a representative bone marrow aspirate morphology.
    • Minimal Residual Disease (MRD): Patients with evidence of minimal residual disease at the completion of therapy or evidence of rising MRD while on therapy. MRD will be defined by either flow cytometry (>0.1% residual cells in the blast gate with immune phenotype of original leukemic clone), by molecular techniques (PCR or FISH) or conventional cytogenetics (g-banding).
  • Recipients must have a Lansky score > or = 50% and have acceptable organ function defined as:

    • Renal: glomerial filtration rate > 60ml/min/1.73m^2
