Exclusion criteria

Exclusion criteria: Exclusion Criteria for Epidermolysis Bullosa Cohort: 1)Diseases or conditions that could interfere with the assessment of safety and efficacy of the study treatment and compliance of the subject with study visits/procedures. 2)Chronic or current active infection or disease requiring systemic antibiotics, antifungal, or antiviral treatment such as, but not limited to, chronic renal infection, chronic chest infection with bronchiectasis, tuberculosis, active Hepatitis B, active Hepatitis C, and known Human Immunodeficiency Virus (HIV) disease. All HIV-positive subjects are excluded from this trial 3)EB target wound with clinical signs (e.g. wound exudate) of local infection at day of baseline visit. 4)Administration of immunosuppressive agents. Use of systemic steroids within 30 days before baseline visit should be discussed with Lead Principal Investigator to determine patient’s eligibility. 5)Current and/or former malignancy including basal cell carcinomas and squamous cell carcinomas. 6)Enrolment in any interventional study or treated with any investigational drug for any disease within 4 weeks prior to study entry. 7)Pregnant or nursing women.

Primary

MeasureTime frame
Main Objective: The main objective of the trial is to evaluate the safety of BIOOPA dressing. ;Secondary Objective: To evaluate the efficacy of BIOOPA dressing. To evaluate the efficacy of BIOOPA dressing in the treatment of chronic wounds. To evaluate Immunogenicity/ immunization To evaluate cells proliferation and vascularization To compare efficacy of BIOOPA dressing to standard treatment in the treatment of chronic wounds in the course of EB for patients with two wounds of similar area To evaluate changes in pain To evaluate changes in itch To evaluate presence of collagen VII for patients with Dystrophic Epidermolysis Bullosa. To evaluate presence of collagen VII, Integrin and Laminin for patients with Junctional Epidermolysis Bullosa. To evaluate Differences in quality of life data.;Primary end point(s): Evaluation of BIOOPA dressing safety by: Incidence and severity of adverse events related to the ATIMP. Incidence and severity of serious adverse events related to the ATIMP Incidences of Grade 3 and 4 wound (with BIOOPA dressing) infections. Incidence of BIOOPA rejection. ;Timepoint(s) of evaluation of this end point: Evaluation of BIOOPA dressing safety will be evaluated at every patient's visit, starting from visit 2 (baseline visit) to visit 8 (follow-up visit).

Secondary

MeasureTime frame
Timepoint(s) of evaluation of this end point: BIOOPA dressing engraftment - assessed by wound biopsy at Day 30. Evaluation of efficacy of BIOOPA dressing - will performed at each patient's visit starting from visit 2 to visit 8. Evaluation of immunogenicity/immunization will be assessed at visit 7. Evaluation of cells proliferation and vascularization will be performed at visit 5 by wound biopsy. Change in pain will be assessed at each patient's visit. Change in itch will be assessed at each patient's visit. Level of collagen VII for patient with dystrophic type of EB will be assesed by wound biopsy at visit 5. Level of collagen VII, Integrin and Laminin for patients with junctional EB will be measured by wound biopsy at visit 5. Quality of life will be assessed at visit 2, visit 5 and at visit 7.;Secondary end point(s): BIOOPA dressing engraftment The mean change in treated wound area (cm2) Percentage change in wound surface area reduction Complete response defined as complete (100%) wound healing Partial response defined as reduce the wound surface area (cm2) by 50% Time to complete response defined as time, in days, from baseline to initial observation of complete wound healing. Time to partial response, defined as time, in days, from baseline to initial observation of 50% reduction of wound surface area. Evaluation of Immunogenicity/ immunization by assessment of blood serum markers: % PRA, CD4 and CD8 level, TNF-a, IL-6. Evaluation of cells proliferation and vascularization by wound biopsy and assessment of: Mesenchymal Cells markers (CD105, CD90, CD73), Kai 67, IL-2R (CD25), Vimentyn, P16, p53 and mutant p53 , KRT5, KRT14, Integrin beta-1 (CD29) The mean change in treated wound surface area (cm2) from baseline in wounds treated with BIOOPA dressing compared with those treated with standard, dressing for patients with two similar wounds. Changes in itch using the numeric rating scale. Changes in pain using the numeric rating scale. Level of collagen VII i
