This is an open-label, single institution, phase II study in patients with epidermolysis bullosa (EB). The underlying hypothesis is that the infusion of bone marrow or umbilical cord blood from a healthy unaffected donor will correct the collagen, laminin, integrin, or plakin deficiency and reduce the skin fragility characteristic of severe forms of EB.
- Diagnosis of severe form of epidermolysis bullosa (EB) characterized by collagen, laminin, integrin, keratin or plakin deficiency. Assessment criteria for severe EB:
- Documented collagen, laminin, integrin, keratin or plakin deficiency (by immunofluorescence staining with protein specific antibodies or Western blotting and by mutation analysis)
- Adequate Organ Function Criteria
- Renal: glomerular filtration rate within normal range for age
- Hepatic: bilirubin, aspartate aminotransferase/alanine aminotransferase (AST/ALT), Alkaline phosphatase (ALP) < 5 x upper limit of normal
- Pulmonary: adequate pulmonary function in the opinion of the enrolling investigator
- Cardiac: left ventricular ejection fraction ≥ 45%, normal electrocardiogram (EKG) or approved by Cardiology for transplant.
