Trial Snapshot

No summary available.

•1. Male or female, with a clinical diagnosis of RDEB with confirmation of at least one of the alleles of the COL7A1 gene containing one or more pathogenic mutations in exon 73, = 18 years of age at Screening:
•- Subjects aged 12 to =18 will be considered for enrollment only after review of data from at least 2 subjects >18 years of age.
•- Subjects aged 6 to <12 will be considered for enrollment only after review of data from subjects 12 to = 18 years of age.
•2. Have at least one TWA of 10 x 10 cm that shows dynamic wound healing, no signs of local infection and in which a wound can be selected with the following criteria:
•a. a surface area ranging from 5 to 60 cm2
•b. open wound that has healing potential
•c. exposed sub-epidermal tissue to allow absorption of the IMP
•d. no suspicion of current squamous cell carcinoma (SCC) upon visual inspection
•Are the trial subjects under 18? yes
•Number of subjects for this age range: 4
•F.1.2 Adults (18-64 years) yes

•F.1.3 Elderly (>=65 years) no
•F.1.3.1 Number of subjects for this age range

•1. Pregnant or breast-feeding female
•2. Hemoglobin level at Screening requiring transfusion. The subject may be rescreened when the condition is considered stable

•4. Life expectancy less than 6 months, as assessed by the Investigator
•5. Current or known history of clinically significant hepatic or renal disease, that in the opinion of the Investigator, could impact subject safety or study participation.
•6. Treatment with any systemic immunomodulators, immunosuppressants or cytotoxic chemotherapy within 2 months prior to the Baseline visit.
