A Phase II, Placebo Controlled, Clinical Trial of Topical TolaSure Targeting Aggregated Mutant Keratin in Epidermolysis Bullosa Simplex

Inclusion Criteria: * Patient is a male or female at least 4 years of age. * Patient has a documented diagnosis of generalize intermediate (previously Kӧbner) to severe (previously EBS-DM) autosomal dominant epidermolysis bullosa simplex (EBS) and/or genetic mutation in either the K14 or K5 genes consistent with generalized intermediate to severe EBS. The Investigator will determine patient eligibility based on historical phenotypic presentation of EBS symptoms along with genetic/diagnosis documentation in order to determine EBS severity. (If generalized intermediate to severe EBS is suspected but not diagnosed or genetically confirmed, confirmatory testing will be performed). * Patient is actively flaring in one of the preferred target lesional areas (TLAs): 1) lower extremities (ideally below the knee and above the ankle or between the knee and top of the thigh) or 2) torso (excluding the groin and apocrine areas). The following skin conditions are required for treatment purposes: * A flare is defined as a minimum area of \~2-3% Body Surface Area (BSA) containing intact blisters (of varying size and number), and freshly ruptured blisters across 50% of the TLA (as assessed by the principal investigator (PI)). Skin erosions, keratoderma, fissures and/or erythema may also be present. * Patients will be permitted to treat their feet to assess plantar blister surface area but blistering on the feet is not a requirement for study inclusion. * TLA may not be infected (as a…
