Transplantation of Umbilical Cord Blood From Related and Unrelated Donors
OBJECTIVES:
Primary
- Determine the engraftment potential of umbilical cord blood (UCB) in patients with
hematological cancers.
- Determine the safety of UCB transplantation in these patients.
Secondary
- Determine the rate of neutrophil and platelet recovery and the completeness of donor
cell engraftment.
- Determine the incidence and severity of acute and chronic graft-versus-host disease.
- Determine the incidence of relapse in patients with malignant disease.
- Determine the probabilities of survival and event-free survival (EFS) at 1 and 2 years
after UCB transplantation.
OUTLINE: Patients are stratified according to degree of HLA disparity (0-1 vs 2-3
disparities between donor and recipient), donor type (related vs unrelated), and the basis
of cell dose (< 2 vs ≥ 2 x 10^7 nucleated cells/kg recipient body weight). Patients are
assigned to 1 of 4 treatment groups according to disease*.
NOTE: *Patients with acute lymphocytic leukemia (ALL), secondary acute myeloid leukemia
(AML), severe combined immunodeficiency, familial erythrophagocytic lymphohistiocytosis
(FEL)/viral-associated hemophagocytic syndrome (VAHS), inborn errors of metabolism, aplastic
anemia, Fanconi's anemia, or Diamond-Blackfan anemia who have an unrelated umbilical cord
blood donor may proceed directly to transplantation.
- Preparative regimen:
- Group 1 (patients with chronic myelogenous leukemia, AML, myelodysplastic
syndromes, or ALL): Patients receive cyclophosphamide IV once daily on days -7 and
-6. Patients then undergo total-body irradiation (TBI) twice daily on days -4 to
-1. Patients undergoing unrelated allogeneic umbilical cord blood transplantation
(UCBT) also receive methylprednisone IV and anti-thymocyte globulin (ATG) IV twice
daily on days -2 and -1.
- Group 2 (patients with infant leukemia): Patients receive busulfan orally or IV
four times daily on days -9 to -6 and melphalan IV once daily on days -4 to -2.
Patients undergoing unrelated allogeneic UCBT also receive methylprednisolone IV
and ATG IV twice daily on days -2 and -1.
- Group 3 (patients with inborn errors of metabolism): Patients receive busulfan
orally or IV four times daily on days -9 to -6 and cyclophosphamide IV once daily
on days -5 to -2. Patients undergoing unrelated allogeneic UCBT also receive
methylprednisolone IV and ATG IV twice daily on days -2 and -1.
- Group 4 (patients with aplastic anemia): Patients receive cyclophosphamide IV once
daily on days -6 to -3 and ATG IV twice daily on days -5 and -3. Patients then
undergo TBI once on day -2.
- Allogeneic UCBT: Patients undergo UCBT on day 0. Patients with inborn errors of
metabolism receive methylprednisolone IV before and after UCBT on day 0.
- Graft-versus-host disease (GVHD) prophylaxis: Patients receive 1 of the following
regimens:
- Related donor UCBT: Patients receive cyclosporine IV over 2 hours or orally
beginning on day -3 and continuing until day 60.
- Unrelated donor UCBT and myeloablative preparative regimen: Patients receive
cyclosporine orally or IV over 2 hours twice daily beginning on day -3 and
continuing until day 180. Patients also receive methylprednisolone IV twice daily
on days 5-19.
- Unrelated donor UCBT and nonmyeloablative preparative regimen: Patients receive
cyclosporine IV over 2 hours or orally twice daily beginning on day -3 and
continuing until day 180. Patients also receive mycophenolate mofetil IV or orally
beginning on day 5 and continuing until day 30 or 7 days after active GVHD is
controlled.
All patients receive filgrastim (G-CSF) IV beginning on day 1 and continuing until blood
counts recover.
Patients are followed periodically for 2 years.
PROJECTED ACCRUAL: A total of 60 patients will be accrued for this study.
