Eligibility Criteria
Inclusion:
- A 4/6, 5/6 or 6/6 HLA matched related or unrelated UCB unit available that will deliver a pre-cryopreservation total nucleated cell dose of ≥ 3 x 10e7 cells/kg, or double unit grafts, each cord blood unit delivering at least 2 x 10e7 cells/kg OR an 8 of 8 or 7 of 8 HLA allele level matched unrelated donor bone marrow or peripheral blood progenitor graft.
Adequate organ function as measured by:
- Creatinine ≤ 2.0 mg/dL and creatinine clearance ≥ 50 mL/min/1.73 m2.
- Hepatic transaminases (ALT/AST) ≤ 4 x upper limit of normal (ULN).
- Adequate cardiac function by echocardiogram or radionuclide scan (shortening fraction > 26% or ejection fraction > 40% or > 80% of normal value for age).
- Pulmonary evaluation testing demonstrating CVC or FEV1/FVC of ≥ 50% of predicted for age and/or resting pulse oximeter ≥ 92% on room air or clearance by the pediatric or adult pulmonologist. For adult patients DLCO (corrected for hemoglobin) should be ≥ 50% of predicted if the DLCO can be obtained.
- Written informed consent and/or assent according to FDA guidelines.
- Negative pregnancy test if pubertal and/or menstruating.
- HIV negative.
