E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the safety of allogeneic intravenously administered MSCs in children with RDEB over a 24-month period. |
|
E.2.2 | Secondary objectives of the trial |
• Incidence of infusional toxicity. • Increase in C7 deposition at the DEJ post treatment at D0 and D60. • Quantitative analysis of the donor cells chimerism at D60. • Improvement of haematological and serological markers of generalised inflammation at D0, D7, D28, D60 and D180 compared to baseline. • Improvement in the clinical appearances of the skin. • Improved quality of life according to validated paediatric QoL scoring systems at screening, D60, D100 and D180. • Pain scoring at screening, D0, D7, D28, D60, D100 and D180. • Reduction in blister occurrence over entire body surface at D0, D7, D28, D60, D100 and D180 as compared to baseline. • Increase in skin strength measured by time to blister formation after skin suction at screening and D100.

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1) Subjects who have a diagnosis of recessive dystrophic epidermolysis bullosa (RDEB) characterised by partial or complete C7 deficiency. 2) Subjects who are ≥ 12 months and ≤ 17 years of age at the time of enrolment. 3) Subjects whose responsible parent/guardian has voluntarily signed and dated an Informed Consent Form (ICF) prior to the first study intervention. Whenever the minor child is able to give consent, the minor’s assent will be obtained in addition to the signed consent of the minor’s legal guardian.
|
|
E.4 | Principal exclusion criteria |
Subjects will be excluded from the study if ANY of the following conditions exist: 1) Subjects who have had other investigational medicinal products within 90 days prior to screening or during the treatment phase. 2) Subjects who have received immunotherapy including oral corticosteroids for more than 1 week (intranasal and topical preparations are permitted) or chemotherapy within 60 days of enrolment into this study. 3) Subjects with a known allergy to any of the constituents of the investigational product. 4) Subjects with signs of active infection. 5) Subjects with a medical history or evidence of malignancy, including cutaneous squamous cell carcinoma. 6) Subjects with both a) positive C7 ELISA and b) a positive indirect immunofluorescence (IIF) with binding to the base of salt split skin. 7) Subjects who are pregnant or of child-bearing potential who are not abstinent or practicing an acceptable means of contraception, as determined by the Investigator, for the duration of the treatment phase.

E.5 End points |
E.5.1 | Primary end point(s) |
Lack of serious and severe adverse events (SAEs) related to the administration of the investigational medicinal product over a 12-month follow-up period. SAEs are defined as any occurrences related to the administration of the IMP that result in death, or is life-threatening or requires hospitalisation or prolongation of existing hospitalisation. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
at every visit up to 12-months after last IMP infusion |
|
E.5.2 | Secondary end point(s) |
•Incidence of infusional toxicity. •Increase in collagen VII deposition at the DEJ post treatment. •Quantitative analysis of the donor cells dermal chimerism. •Improvement of haematological and serological markers of generalised inflammation. •General clinical appearance of the skin based on medical photographs, generalised severity score and BEBSS score. •Improved quality of life. •Pain scoring. •Reduction in blister numbers. •Increase in skin strength measured by increased time to blister formation after skin suction |
|
