About this study

Official title: 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.

Read the 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 being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Patients With Detectable Collagen Type VII

    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.

    Measured: Day 100 Post Transplant

Secondary outcomes (9)
  1. Number of Patients With >70% Donor Chimerism

    Number of patients with donor chimerism - percentage of donor cells in the patient via the peripheral blood or bone marrow.

    Measured: Days 21, 100, 180, 365 and 730 Post Transplant

  2. Number of Patients With Transplant-Related Mortality

    Number of patients who died due to complications of the transplant (includes all deaths without previous relapse or progression).

    Measured: Day 180 Post Transplant

  3. Number of Patients With Platelet Engraftment

    Number of patients with a platelet count >5 x 10^10 cells/liter for 3 consecutive measurements.

    Measured: Day 180 Post Transplant

  4. Number of Patients With Acute Graft-Versus-Host Disease (GVHD)

    Number of patients with GVHD. Acute Graft-Versus-Host Disease is a severe short-term complication created by infusion of donor cells into a foreign host.

    Measured: Day 100 Post Transplant

  5. Number of Patients With Chronic Graft-Versus-Host Disease (cGVHD)

    Number of patients with cGVHD; a severe long-term complication created by infusion of donor cells into a foreign host.

    Measured: Day 365 Post Transplant

  6. Overall Survival

    Survival is defined as the number of patients that were alive post transplant.

    Measured: 1 year and 2 years Post Transplant

  7. Number of Patients With Donor Derived Cells in Skin

    Number of patients who had donor skin chimerism - donor cells in the patient's epidermis (a state in bone marrow transplantation in which bone marrow and host cells exist compatibly without signs of graft-versus-host rejection disease).

    Measured: Day 90 Post Transplant

  8. Number of Patients With Resistance to Blister Formation

    Resistance to Blister Formation demonstrated by response to negative pressure.

    Measured: Month 1 through Month 24 Inclusive

  9. Number of Patients With Neutrophil Engraftment

    Number of patients with an absolute neutrophil count >5 x 10^8 cells/liter for 3 consecutive days.

    Measured: Day 42 Post Transplant

Questions about this trial

What is this clinical trial studying?

A study testing busulfan, cyclophosphamide and fludarabine phosphate in people with Epidermolysis Bullosa, run by Masonic Cancer Center, University of Minnesota at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 15 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 28 Dec 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 11 Feb 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Patients With Detectable Collagen Type VII (time frame: Day 100 Post Transplant). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00478244, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Dec 2017.
