About
This phase II trial studies how well giving an umbilical cord blood transplant together with cyclophosphamide, fludarabine, and total-body irradiation (TBI) works in treating patients with hematologic disease. Giving chemotherapy, such as cyclophosphamide and fludarabine, and TBI before a donor umbilical cord blood transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's 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 after transplant may stop this from happening.
Full description
OUTLINE: Patients are assigned to 1 of 2 arms.
ARM I: Patients receive myeloablative conditioning comprising fludarabine intravenously (IV) over 30 minutes on days -8 to -6, cyclophosphamide IV on days -7 and -6, and undergo high-dose TBI twice daily (BID) on days -4 to -1. Patients then undergo single- or double-unit UCBT on day 0.
ARM II: Patients receive myeloablative conditioning comprising fludarabine IV over 30-60 minutes on days -6 to -2, cyclophosphamide IV on day -6, thiotepa IV over 2-4 hours on days -5 and -4, and middle-intensity TBI once daily (QD) on days -2 and -1. Patients then undergo single- or double-unit UCBT on day 0.
Patients receive GVHD prophylaxis comprising cyclosporine IV over 1 hour every 8 or 12 hours, then cyclosporine orally (PO) (if tolerated), on days -3 to 100 with taper on day 101. Patients also receive mycophenolate mofetil IV every 8 hours on days 0 to 7 and then PO (if tolerated) three times daily (TID) on days 8-30. Mycophenolate mofetil is tapered to BID on day 30 or 7 days after engraftment if there is no acute GVHD, and then tapered over 2-3 weeks beginning on day 45 (or 15 days after engraftment if engraftment occurred > day 30) after engraftment if there continues to be no evidence of acute GVHD.
After completion of study treatment, patients are followed up at 6 months, 1 year, and 2 years.

Inclusion criteria
-
GRAFT CRITERIA:
- UCB units will be selected according to current umbilical cord blood graft selection algorithm; one or 2 UCB units may be used to achieve the required cell dose
- The UCB graft is matched at 4-6 human leukocyte antigen (HLA)-A, B, DRB1 antigens with the recipient; this may include 0-2 antigen mismatches at the A or B or DRB1 loci; unit selection based on cryopreserved nucleated cell dose and HLA-A,B, DRB1 using intermediate resolution A, B antigen and DRB1 allele typing
- If 2 UCB units are required to reach the target cell dose, each unit must be a 4-6 antigen match to the recipient
-
Age and Disease Criteria:
- High-dose TBI regimen: 6 months to =< 45 years
- Middle-intensity TBI regimen: 6 months to =< 65 years
- Conditioning regimen selection should be based on the underlying disease, presence of minimum residual disease (MRD), age, co-morbidities, and attending physician
-
Acute myeloid leukemia, including biphenotypic acute leukemia or mixed-lineage leukemia:
- All patients must be in complete remission (CR) as defined by hematologic recovery and < 5% blasts by morphology/flow cytometry in a representative bone marrow sample with cellularity >= 15% for age; patients who do not have high-risk features (for example preceding myelodysplastic syndrome [MDS], high-risk cytogenetics, >= 2 cycles to obtain CR, erythroblastic or megakaryocytic leukemia or >= CR2) must be discussed with the principal investigator (PI) prior to enrollment and at the Patient Care Conference or equivalent group such as the pediatric leukemia board as an alternative
- Patients in whom adequate marrow/biopsy specimens cannot be obtained to determine remission status by morphologic assessment, but have fulfilled criteria of remission by flow cytometry, recovery of peripheral blood counts with no circulating blasts, and/or normal cytogenetics (if applicable) may still be eligible; reasonable attempts must be made to obtain an adequate specimen for morphologic assessment, including possible repeat procedures; these patients must be discussed with the PI prior to enrollment; patients persistently aplastic for greater than one month since completing last chemotherapy are also eligible with PI approval
-
Very high risk pediatric/young adult patients with acute myeloid leukemia (AML): Patients =< 25 years, however, are eligible with (M2 marrow) with =< 25% blasts in marrow after having failed one or more cycles of chemotherapy; this group of patients will be analyzed separately
-
Acute lymphoblastic leukemia, including biphenotypic acute leukemia or mixed-lineage leukemia:
- All patients must be in CR as defined by < 5% blasts by morphology; flow cytometry in a representative bone marrow sample with cellularity >= 15% for age; patients who do not have high-risk disease (high risk CR1, greater than one cycle to obtain CR or >= CR2) must be discussed with the PI prior to enrollment and at the Patient Care Conference or equivalent group such as the pediatric leukemia board as an alternative
- Patients in whom adequate marrow/biopsy specimens cannot be obtained to determine remission status by morphologic assessment, but have fulfilled criteria of remission by flow cytometry, recovery of peripheral blood counts with no circulating blasts, and/or normal cytogenetics (if applicable) may still be eligible; reasonable attempts must be made to obtain an adequate specimen for morphologic assessment, including possible repeat procedures; these patients must be discussed with the principal investigator Ann Dahlberg prior to enrollment; patients persistently aplastic for greater than one month since completing last chemotherapy are also eligible with PI approval
