MT2013-31:Allogeneic Hematopoietic Cell Transplantation for Inherited Metabolic Disorders and Severe Osteopetrosis following Conditioning with Busulfan (Therapeutic Drug Monitoring), Fludarabine +/- ATG


To evaluate the ability to achieve high-level donor hematopoietic engraftment (defined as neutrophil recovery by Day +42 post-transplant and ≥ 80% donor cells on the myeloid fraction of peripheral blood at Day +100 post-transplant) using related and unrelated BM, PBSC, or UCB grafts following a reduced intensity conditioning regimen based on targeted-exposure busulfan, fludarabine +/- serotherapy in patients with inherited metabolic disorders and severe osteopetrosis.

• MPS VI (Maroteaux-Lamy syndrome)
• MPS VII (Sly syndrome)
• Glycoprotein Metabolic Disorders:
• Alpha mannosidosis
• Fucosidosis
• Aspartylglucosaminuria
• Sphingolipidoses and Recessive Leukodystrophies:
• Globoid cell leukodystrophy
• Metachromatic leukodystrophy
• Niemann-Pick B patients (sphingomyelin deficiency)
• Niemann-Pick C subtype 2
• Peroxisomal Disorders:
• Adrenoleukodystrophy with cerebral involvement
• Zellweger syndrome
• Neonatal Adrenoleukodystrophy
• Infantile Refsum disease
• Acyl-CoA-Oxidase Deficiency
• D-Bifunctional enzyme deficiency

• Mitochondrial Neurogastrointestingal Encephalopathy (MNGIE)
• Severe Osteopetrosis (OP)
• Hereditary Leukoencephalopathy with axonal spheroids (HDLS; CSF1R mutation)
• Other Inherited Metabolic Disorders (IMD): Patients will also be considered who have other life-threatening, rare lysosomal, peroxisomal or other similar inherited disorders characterized by white matter disease or other neurologic manifestations for which there is rationale that transplantation would be of benefit, such as certain patients with Wolman's disease, GM1 gangliosidosis, I-cell disease, Tay-Sachs disease, Sandhoff disease or others.
• Voluntary written consent
Exclusion Criteria:

• Pregnancy - menstruating females must have a negative serum or urine pregnancy test within 14 days of study treatment start
• Prior myeloablative chemotherapy exposure within 4 months of the start of conditioning on this protocol (patients excluded for this reason may be eligible for other institutional protocols)
• Uncontrolled bacterial, fungal or viral infections including HIV (including active infection with Aspergillus or other mold within 30 days)
