Brief Summary:
This randomized phase II trial studies how well donor umbilical cord blood transplant with or without ex-vivo expanded cord blood progenitor cells works in treating patients with acute myeloid leukemia, acute lymphoblastic leukemia, chronic myelogenous leukemia, or myelodysplastic syndromes. Giving chemotherapy and total-body irradiation before a donor umbilical cord blood transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's cells. When the healthy stem cells and ex-vivo expanded cord blood progenitor cells are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. It is not yet known whether giving donor umbilical cord blood transplant plus ex-vivo expanded cord blood progenitor cells is more effective than giving a donor umbilical cord blood transplant alone.
Detailed Description:
PRIMARY OBJECTIVES:
I. Compare the time to neutrophil engraftment (absolute neutrophil count \[ANC\] \>= 500) in patients receiving a standard of care myeloablative cord blood transplant (CBT) augmented with an off-the-shelf pre-expanded and cryopreserved cord blood product to those who do not receive the product.
SECONDARY OBJECTIVES:
I. Provide initial data on clinical and economic benefit, such as time to platelet engraftment, duration of initial hospitalization, transplant-related mortality (TRM), death without engraftment, and incidence of severe infections in the first 100 days post-transplant.
II. The kinetics of immune system recovery will also be evaluated in both arms.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
Standard of Care Arm:
CONDITIONING REGIMEN: One of two possible conditioning regimens is chosen by the attending physician: Patients receive fludarabine phosphate intravenously (IV) over 30 minutes on days -8 to -6, cyclophosphamide IV on days -7 to -6., and undergo high dose total-body irradiation (TBI) twice daily (BID) on days -4 to -1 OR, patients receive fludarabine phosphate IV over 30-60 minutes on days -6 to -2, cyclophosphamide IV on day -6, thiotepa IV over 4 hours on days -5 to -4, and undergo middle intensity TBI once daily (QD) on days -2 to -1.
TRANSPLANT: Patients undergo single-unit or double-unit unmanipulated umbilical cord blood (UCB) transplant on day 0.
GRAFT-VERSUS-HOST DISEASE (GVHD) PROPHYLAXIS: Patients receive cyclosporine IV over 1 hour BID (adults) or thrice daily (TID) (children) or orally (PO) on days -3 to 100 with taper beginning on day 101. Patients also receive mycophenolate mofetil (MMF) IV TID on days 0-7 then may receive MMF PO TID. Patients remain on MMF TID for a minimum of 30 days, and then may begin taper if there is no evidence of GVHD and are well-engrafted from one donor unit.
Experimental Arm:
CONDITIONING REGIMEN: Patients receive the conditioning regimen chosen by the attending physician as in Standard of Care Arm.
TRANSPLANT: Patients undergo single-unit or double-unit unmanipulated UCB transplant on day 0. Patients also receive an infusion of ex vivo-expanded cord blood progenitors at least 4 hours after completion of UCB transplant.
GVHD PROPHYLAXIS: Patients receive cyclosporine IV or PO and mycophenolate mofetil IV or PO as in Standard of Care Arm.
After completion of study treatment, patients are followed up periodically for 2 years.
