Allogeneic Hematopoietic Stem Cell Transplant For Epidermolysis Bullosa
Allogeneic Hematopoietic Cell Transplantation to Correct the Biochemical Defect and Create Tolerance to Donor Tissue in Subjects With Epidermolysis Bullosa
RATIONALE: In animal models, stem cells have been shown to home to the skin and repair the biochemical and structural abnormalities associated with recessive dystrophic epidermolysis bullosa (RDEB) (collagen 7 deficiency).
PURPOSE: To determine the safety and effectiveness of stem cell infusion in the treatment of RDEB.

Detailed Description
OBJECTIVES:
Primary
- Estimate the incidence of detectable donor-derived collagen type VII at day 100 in patients with epidermolysis bullosa by donor.
Secondary
- Determine the incidence of transplant-related mortality at day 180
- Determine the incidence of blood chimerism at days 21, 100, 180, 365, and 730
- Determine the incidence of neutrophil recovery at day 42 and platelet recovery at day 180
- Determine the incidence of acute graft-versus-host disease (GVHD) grade II-IV and grade III-IV at day 100
- Determine the incidence of chronic GVHD at 1 year
- Determine the probability of survival at 1 and 2 years
- Determine the incidence of donor derived cells in the skin
- Determine resistance to blister formation OUTLINE: This is an open-label, pilot study.
- Conditioning regimen: Busulfan intravenously (IV) over 2 hours every 6 hours on days -9 to -4, fludarabine phosphate IV over 1 hour on days -5 to -3, and high-dose cyclophosphamide IV over 1 hour on days -5 to -2.
- Stem cell transplantation on day 0.
After completion of study treatment, patients are followed periodically for at least 5 years.

Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Patients With Detectable Collagen Type VII
Time Frame: Day 100 Post Transplant
|
Number of patients with epidermolysis bullosa who had collagen type VII.
Type VII collagen defects cause recessive dystrophic epidermolysis bullosa (RDEB), a blistering skin disorder often accompanied by epidermal cancers.
|
Day 100 Post Transplant
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |

---|---|---|
Number of Patients With >70% Donor Chimerism
Time Frame: Days 21, 100, 180, 365 and 730 Post Transplant
|
Number of patients with donor chimerism - percentage of donor cells in the patient via the peripheral blood or bone marrow.
|
Days 21, 100, 180, 365 and 730 Post Transplant
|
Number of Patients With Transplant-Related Mortality
Time Frame: Day 180 Post Transplant
|
Number of patients who died due to complications of the transplant (includes all deaths without previous relapse or progression).
|
Day 180 Post Transplant
