Brief Summary:
Phase I / II pilot clinical trial, to evaluate the safety and preliminary efficacy of the systemic infusion of mesenchymal stem cells derived from bone marrow (BM-MSCs) from a haploidentical donor to improve the healing process and / or the mucocutaneous fragility phenotype associated with EBDR.

Condition or disease Intervention/treatment Phase
Epidermolysis Bullosa Dystrophica, Recessive Biological: mesenchymal stem cells derived from bone marrow (BM-MSCs) Phase 1 Phase 2

Detailed Description:

The Main Objective is to evaluate the safety and therapeutic efficacy of haploidentical MSCs derived from bone marrow administered by intravenous injection for the treatment of patients with RDBS. The assessment of the symptomatic improvement of the treated patients will be made regarding the baseline situation and the response to treatment at the biochemical, histological and molecular level.

Secondary Objectives:

Describe the clinical and molecular phenotype of the mucocutaneous involvement of patients, including the characterization of the mutations responsible for the disease.

Study drug: Allogenic mesenchymal cells (haploidentical) derived from bone marrow and expanded.

Method of administration: Systemic / Intravenous Administration dose: 2-3x10e6 BM-MSC / Kg. Weekly dose for three consecutive weeks

Follow-up period: 12 months after the infusion. However, patients will be monitored outside the clinical trial over a 5-year period

    The Epidermolysis Bullosa Disease Activity and Scarring Index (EBDASI) used to classify patients according to disease severity and clinical response in three types: mild, moderate and severe (obtained by the analysis of 12 skin sites in addition to the scalp, mucous membranes, nails and other epithelized surfaces - total activity (of 276) and damage (of 230) combine to give an overall score of 506; where 0 = better outcome and 506 = worse outcome).

  11. Expression of Collagen VII (C7) in skin biopsy [ Time Frame: 2 year after infusion ]
    Expression of Collagen VII (C7) in skin biopsy will be analyzed by immunofluorescence with antibodies specific for the NC1 domain of collagen VII.

    Analysis of anchoring fibrils by electron microscopy in skin biopsy after treatment

  13. Variation of pain respect to baseline status: Visual Analog Scale [ Time Frame: 2 year after infusion ]
    Variation of pain with respect to baseline that will be assessed using the Visual Analogy Scale (VAS) in all visits after the first infusion, used different type of VAS scale depends on age of subject. Range was 1 to 10, where 10 are considered a worse outcome.

  14. Modification in itching perceived [ Time Frame: 2 year after infusion ]
    Assessment of the change in the itching perceived respect baseline status will be assessed by Leuven Itch Scale or Itch Man Scale, depends on the age of the subject. These scales are the instrument to evaluate itching perceived in patients with pruritus origin different. There subscale in 6 domains: frequency, duration, severity, distress, impact, and area: Itch frequency score: scale from 0 to 100. (Maximum score 100, itching all the time - is worse outcome) Itch severity score: scale from 0 to 100 (Maximum score 100, maximum severity =worse outcome) Itch distress score: scale from 0 to 100 (Maximum score 100, maximum distress = worse outcome) Itch consequences score: scale from 0 to 100 (Maximum score 100, maximum consequences = worse outcome) Itch Surface area score: Scale from 0 to 100 (Maximum score is 100, the entire body = worse outcome).

  15. Change in quality of life of patient: European Quality of Life-5 Dimensions-5 level (EUROQL-5D) [ Time Frame: 2 year after infusion ]
    Assessment of the change in quality of life: survey of specific assessment of the quality of life (European Quality of Life-5 Dimensions-5 level; EUROQL-5D). The descriptive system comprises five dimensions: mobility, self-care, habitual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels of gravity, where a value of 1 is better outcome and 3 is worse outcome. Also, there are a 2nd part included a VAS scale, where 0 = worse outcome and 100 =better outcome.

    Evaluation of the changes produced in the patient before and after the study treatment, assessing according to the set of tests performed on the patient during the same; indicating it through a Likert scale, from 1-4, where 4 is the most serious evaluation and 1 is the slightest.
