Patients undergo TBI on day -1. Patients then undergo donor UCBT on day 0. Patients receive GVHD prophylaxis comprising cyclosporine IV over 1 hour or orally (PO) 2-3 times daily on days -3 to 100, followed by a taper in the absence of GVHD. Patients also receive mycophenolate mofetil IV 3 times daily on days 0 to 40, followed by a taper in the absence of GVHD.
ARM II (high risk for graft failure): Patients receive a conditioning regimen, TBI, donor UCBT, GVHD prophylaxis, and mycophenolate mofetil as in Arm I.

- DONOR: Any cord blood units that have not passed donor screening for infectious disease markers as recommended by NMDP will not be used unless a waiver is signed by the clinical attending allowing use of CB unit. Cord blood units are presumed to be cytomegalovirus (CMV) negative regardless of serologic testing due to passive transmission of maternal CMV antibodies

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants With Graft Failure/Rejection
Time Frame: Up to 100 days
|
Patients will be considered primary graft failure provided they meet any criteria listed below, in the absence of documented disease persistence/recurrence or active bone marrow infection (ex. Cytomegalovirus (CMV)): i. Absence of 3 consecutive days with neutrophils >500/u1 combined with host CD3+ peripheral blood chimerism ≥50% at day 42 ii. Absence of 3 consecutive days with neutrophils >500/u1 under any circumstances at day 55 iii. Death after day 28 with neutrophil count <100/u1 without any evidence of engraftment (< 5% donor CD3+) iv. Primary autologous count recovery with < 5% donor CD3+ peripheral blood chimerism at count recovery and without relapse |
Up to 100 days
|
Number of Participants With Secondary Graft Failure
Time Frame: Up to 2 years
|
Secondary graft failure is defined as decline of neutrophil count to <500/ul with loss of donor chimerism after day 55
|
Up to 2 years
|
Number of Patients With Non-relapse Mortality (NRM)
Time Frame: At day -200
|
Defined as death from any cause without sign of disease progression or relapse.
Loss to follow up are censored, whereas disease relapse or progression are considered competing risks.
|
At day -200
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants Surviving by 1 Year
Time Frame: At 1 year
|
Overall survival was measured from the first day of CBT infusion until death from any cause.
|
At 1 year
|
The Number of Participants Alive at Two-years Follow up.
Time Frame: Up to 2 years
|
Overall survival of participants after two-years of follow up.
|
Up to 2 years
|
Non-relapse Mortality
Time Frame: Up to 2 years

|
Up to 2 years
|
Duration (Days) Until Participants Obtained Platelet Engraftment
Time Frame: At 6 months
|
Summarized using a range and median of measure in days until participants reached platelet engraftment.
Platelet engraftment was defined as the first of 7 consecutive days when the platelet count exceeded 20 x 109/L (untransfused).
|
At 6 months
|
Number of Participants With Acute Graft-versus-host Disease (GVHD) Grade II-IV by Day 100
Time Frame: Day 100
|
Grade I GVHD is characterized as mild disease, grade II GVHD as moderate, grade III as severe, and grade IV life-threatening.
Diagnosing and grading acute GVHD is based on clinical findings (the organ stage, response to treatment and whether GVHD was a major cause of death) and frequently varies between transplant centers and independent reviewers.
|
Day 100
|
Incidence of Acute or Chronic Graft-versus-host Disease (GVHD)
Time Frame: At 1 year
|
Overall GVHD is determined based on the organ stage, response to treatment and whether GVHD was a major cause of death.
Chronic GVHD will be defined according to the National Institutes of Health Consensus Development Project on Criteria for Clinical Trials in Chronic Graft-versus-Host Disease.
Described as mild, moderate, or severe as graded according to the attached Organ Scoring Sheet.
Symptoms consistent with both chronic and acute GVHD occurring after day 100 will be considered overlap chronic GVHD syndrome.

Time Frame: Up to 2 years
|
Cumulative incidence estimates using non-relapse mortality as competitive event.
|
Up to 2 years
|
Number of Participants Surviving up to 2 Years Without Disease Progression
Time Frame: Up to 2 years

Progression-free survival is the time interval from start of treatment to documented evidence of disease progression.
Disease progression was defined by European LeukemiaNet 2017 criteria and International Working Group (IWG) within 3 years of transplant.
|
Up to 2 years
|
Incidence of Clinically Significant Infections
Time Frame: At 6 months
