|Condition or disease||Intervention/treatment||Phase|
|Epidermolysis Bullosa||Drug: Cyclophosphamide Drug: Fludarabine Drug: Anti-thymocyte globulin Drug: Cyclosporine A Drug: Mycophenolate mofetil Procedure: Mesenchymal stem cell transplantation Radiation: Total body irradiation Procedure: Bone marrow or umbilical cord blood (UCG) stem cell transplantation||Phase 1 Phase 2|
The primary objective of this study is to estimate the event-free survival rate by 1 year post-transplant with an event defined as a death or failure to have a demonstrable increase in collagen, laminin, integrin, keratin or plakin deposition by 1 year post-transplant or other biochemical, structural or physical measure of improvement.
The secondary objectives of this study are to i) determine the incidence of transplant-related mortality (TRM) at 180 days; ii) describe the pattern of biochemical improvement as measured by an increase in protein expression (collagen, laminin, integrin, keratin or plakin) and related structural and physical changes; iii) describe health quality of life at day 365 and 730 as compared to pretreatment results; iv) describe the pattern and durability of HSC and third party MSC engraftment in the skin; v) determine the probability of survival at 1 year.
Patients with severe epidermolysis bullosa will be screened to meet the eligibility requirements, related or unrelated donor marrow or UCB will be infused, and subjects will be followed for a minimum of 5 years after stem cell transplant. A target accrual of 75 subjects over 5 years will be recruited to the study.
