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.

Study Overview

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.

What is the study measuring?

Primary Outcome Measures

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

Outcome Measure
Measure Description
Time Frame
Number of Patients With >70% Donor Chimerism
Time Frame: Days 21, 100, 180, 365 and 730 Post Transplant
