Efficacy and Safety Study to Evaluate SD-101 in Epidermolysis Bullosa

This is a Phase 3, multi-center, randomized, double-blind, placebo-controlled, study to compare the efficacy and safety of SD-101-6.0 cream vs. placebo (SD 101-0.0) on wounds in patients with Simplex, Recessive Dystrophic, or Junctional non-Herlitz (JEB-nH) EB. SD-101-6.0 cream or placebo (SD-101-0.0) will be applied topically, once a day to the entire body for a period of 60 days. Enrolled patients will have 1 target wound selected at baseline. The selected target wound must be at least 21 days old (size 10 to 50 cm2). Photographic confirmation of the target wound location will be collected at baseline, and the picture saved from the first visit will be used to confirm location of the target wound at subsequent visits. The patient will return to the study site for Visit 2 (14 days ±7 days from baseline), Visit 3 (30 days ±7 days from baseline), and Visit 4 (60 days ±7 days from baseline) to have the target wound re-assessed for the level of healing. Once the target wound is healed, it will be considered healed at subsequent visits and no further re-assessment of the target wound will be conducted The ARANZ SilhouetteStar™ will be used to measure the target wound at all visits until the target wound is documented as closed. Assessment of itching will be evaluated at each visit. In addition, body surface area (BSA), and other secondary endpoints will be evaluated at the baseline and Month 2 visits.
