NCT06713434
This study consists of two phases: an Observational Phase to evaluate the natural history of ocular manifestations in subjects with Dystrophic and Junctional Epidermolysis Bullosa, followed by a Treatment Phase to assess the effects of ELK-003 eye drops. Each subject will serve as their own control by comparing ocular manifestations documented during the Observational Phase to those recorded during the Treatment Phase.
NCT05111600
Prospective, multicenter and multinational, open-label, uncontrolled clinical study to assess the safety and efficacy of autologous cultured epidermal grafts containing epidermal stem cells genetically modified transduced with a LAMB3-gamma retroviral vector. The purpose of this study is to demonstrate the safety and efficacy after one or more treatments with genetically corrected cultured epidermal autograft (Hologene 5) for restoration of the epidermis in patients with generalized intermediate LAMB3-dependent Junctional Epidermolysis Bullosa.
NCT03578029
The objective of this study is to compare the efficacy and safety of RGN-137 topical gel with that of placebo gel for treatment of junctional epidermolysis bullosa (JEB) or dystrophic epidermolysis bullosa (DEB).
NCT04727268
This study will collect genetic and clinical information of junctional epidermolysis bullosa (JEB) patients. Computer analysis will be performed on genetic mutations found in these patients and this will be correlated with their clinical characteristics.
NCT03526159
Herlitz junctional epidermolysis bullosa (H-JEB), an incurable, fatal, inherited skin disease, is caused by loss-of-function mutations in the LAMA3, LAMB3 or LAMC2 genes, resulting in loss of laminin 332 and poor epidermal-dermal adherence. Eighty percent of H-JEB patients have LAMB3 mutations and about 95% of these are nonsense mutations. The investigators recently demonstrated that gentamicin readily induced nonsense mutation readthrough and produced full-length laminin beta3 in several nonsense mutations tested. Importantly, the gentamicin-induced laminin beta3 restored laminin 332 assembly, secretion, and deposition into the dermal-epidermal junction (DEJ). Newly induced laminin 332 reversed abnormal H-JEB cellular phenotypes. Herein, the investigators propose the first clinical trial of gentamicin (by topical and intravenous administration) in JEB patients with nonsense mutations. The milestones will include restored laminin 332 and hemidesmosomes at the DEJ, improved wound closure, and the absence of significant gentamicin side effects.
