Brief Summary

This is a clinical trial of bone marrow transplantation for patients with the diagnosis of a genetic disease of blood cells that do not have an HLA-matched sibling donor. Genetic diseases of blood cell include: Red blood cell defects e.g. hemoglobinopathies (sickle cell disease and thalassemia), Blackfan-Diamond anemia and congenital or chronic hemolytic anemias; White blood cells defects/immune deficiencies e.g. chronic granulomatous disease, Wiskott-Aldrich syndrome,Osteopetrosis, Kostmann's syndrome (congenital neutropenia), Hereditary Lymphohistiocytosis (HLH); Platelets defects e.g.Congenital amegakaryocytic thrombocytopenia; Metabolic/storage disorders e.g. leukodystrophies,mucopolysaccharidoses as Hurler disease;Stem cell defects e.g.reticular agenesis, among many other rare similar conditions.

The study treatment plan uses a new transplant treatment regimen that aims to try to decrease the acute toxicities and complications associated with the standard treatment plans and to improve outcome

The blood stem cells will be derived from either unrelated donor or unrelated umbilical cord blood.

Detailed Description

This is a pilot clinical trial of hematopoietic stem cell transplantation for patients with the diagnosis of a genetic disease of blood cells that do not have an HLA-matched sibling donor. The stem cells will be derived from a 1) matched unrelated donor (MUD) or 2) unrelated umbilical cord blood (UCB). Patients will receive a novel conditioning regimen with Busulfan, Cytoxan and Fludarabine (Bu/Cy/Flu) and either Alemtuzumab (Campath 1H) for recipients of a MUD or rabbit Antithymocyte Globulin (rATG) for recipients of unrelated UCB prior to hematopoietic stem cell transplant (HSCT).

It is hypothesized that reduced dosages of Cytoxan will decrease the acute toxicities associated with the standard chemotherapies of Busulfan and Cytoxan (i.e. sinusoidal obstructive syndrome (SOS), hemorrhagic cystitis and mucositis). And the addition of fludarabine to a conditioning regimen with myeloablative doses of Busulfan and reduced dosages of Cytoxan prior to HSCT will overcome the engraftment barrier posed by an intact immune system, which is seen in patients with a genetic disease.

Eligibility Criteria

Inclusion Criteria

• Lethal or sublethal genetic disease of blood cells, who lack a fully histocompatible sibling or other family donor
• Genetic diseases that would be candidates for this protocol includes those that have been shown to benefit from allogeneic HSCT: Red blood cell defects, Leukocyte defects/ Primary immune deficiencies, Platelets defects, Metabolic/storage disorders and Stem cell defects.
• Renal: creatinine clearance or glomerular filtration rate (GFR) ≥50 ml/min/1.73m2 and not requiring dialysis.
• Pulmonary: FEV1, FVC and DLCO (corrected for hemoglobin) ≥ 50% predicted. if unable to perform pulmonary function tests, then O2 saturation ≥ 92% in room air.
• Cardiac: Left ventricular ejection fraction at rest must be ≥ 40%, or shortening fraction ≥ 26%
• Hepatic: Bilirubin ≤3x upper limit of normal (ULN) and ALT and AST ≤ 5x for age (with the exception of isolated hyperbilirubinemia due to Gilbert's syndrome).
• Patients will be 0-21 years of age.

Exclusion Criteria

• Patient with histocompatible sibling
• End-organ failure that precludes the ability to tolerate the transplant procedure, including the conditioning regimen.
• Creatinine clearance or GFR < 50 ml/min/1.73m2 or renal failure requiring dialysis.
• Congenital heart disease resulting in congestive heart failure.
• Severe residual CNS disease/impairment [(other than hemiplegia alone) e.g. coma or intractable seizures]
• Ventilatory failure
• Major congenital anomalies that adversely affect survival, e.g. CNS malformations
• Lansky score < 40% or Karnofsky score < 60%
• HIV seropositivity
• Diagnosis of Fanconi's anemia, Severe Combined Immunodeficiency (SCID)
• Positive pregnancy test (For female patients in child bearing period)
• Uncontrolled bacterial, viral, or fungal infections (currently taking medication yet clinical symptoms progress)

• Maximum Eligible Age: 21 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: No
