Open Label Extension Study to Evaluate the Long-term Safety of Zorblisa (SD-101-6.0) in Patients With Epidermolysis Bullosa

This was an open label, multi-center extension study to assess the long-term safety of topically applied SD-101-6.0 in participants with simplex, recessive dystrophic, and junctional non-Herlitz EB. SD-101-6.0 was applied topically once a day to the entire body. The planned duration of treatment with SD-101-6.0 for Study SD-006 was up to 48 months, with a safety follow-up period of 30 days; however, the study was terminated early by the sponsor. The maximum study duration completed by at least 1 participant, treatment and safety follow-up, was 37 months. Participants who successfully completed Study SD-005 had the option to rollover into Study SD-006. The screening/baseline visit (Visit 1) occurred at Visit 5 (approximately 90 days from baseline) of Study SD-005. The Body Surface Area (BSA) assessments of lesional skin and wound burden performed at Visit 5 (approximately 90 days from baseline) for Study SD-005 were utilized as the baseline assessments for Study SD-006. Participants returned for follow-up visits at Month 1 then every 3 months. At each visit, assessments included BSA of lesional skin and wound burden. For target wounds that are not closed by the end of Study SD-005, the ARANZ picture and calculation of target wound area at the final visit for Study SD-005 was used as the baseline area size of the target wound for Study SD-006. These unhealed target wounds from Study SD-005 were assessed via ARANZ SilhouetteStar™ at each subsequent scheduled visit until the target wound was documented as closed. Closed wounds were assessed for scarring.
