Overview

The purpose of this study was to assess the continued safety of topical use of SD-101 cream (6%) in participants with Epidermolysis Bullosa (EB). Funding Source: FDA Office of Orphan Products Development

This was an open-label extension study to assess the continued safety of topically applied SD-101 dermal cream (6%) in participants with Simplex, Recessive Dystrophic, and Junctional non-Herlitz EB. SD-101 dermal cream (6%) was applied topically, once a day to the entire body for the duration of the study. Participants who successfully completed the entire SD-003 study (NCT02014376) had the option to roll over into the SD-004 study (NCT02090283). The baseline visit occurred at the final visit date for the SD-003 study. The body surface area (BSA) coverage of blisters and lesions assessment made at the final SD-003 study visit were used as the baseline information at the baseline visit for the SD-004 study. Participants returned to the study site for the following 13 visits (36 months) to have BSA assessed. BSA was assessed at all subsequent scheduled study center visits. Scheduled study center visits occurred every 6 months after Month 36 (Month 42, 48, and so on). After completion of Month 36, the next participant visit (Month 39) was a phone call from the site to the participant. Telephone visits occurred every 6 months thereafter (Month 45, 51, and so on) and included assessment of adverse events and concomitant medications only. For female participants of childbearing potential, a urine pregnancy test was performed at Month 6 and every 6 months up to and including the final study visit.

Interventions

SD-101 dermal cream (6%)DRUG

SD-101 is a white, crystalline powder that is formulated within an odorless, soft, white cream base. SD-101-6.0 cream contains allantoin, a diureide glyoxylic acid, at a concentration of 6% and other excipients.

Outcomes

Primary Outcomes

Number Of Participants With Treatment-Emergent Adverse Events (TEAEs)

Treatment-emergent adverse events were defined as adverse events that started or worsened on or after baseline visit, which occurred at the final visit date for the SD-003 study. A summary of serious and all other non-serious adverse events, regardless of causality, is located in the Reported Adverse Events module.

Time frame: From baseline to 30 days after last application of study drug (up to a maximum of 54 months)

Secondary Outcomes

Change From Baseline In Body Surface Area Index (BSAI) Of Lesional Skin At Month 24

Lesional skin was defined as areas that contained any of the following: blisters, erosions, ulcerations, scabbing, bullae, or eschars, as well as areas that were weeping, sloughing, oozing, crusted, or denuded. The percentage, ranging from 0% to 100%, of affected body surface area (BSA) was recorded for each defined body region (that is, head/neck, upper limbs, trunk \[includes groin\], and lower limbs), multiplied by the weighting factor, and then summed for all body regions to calculate the BSAI. The BSA for lesional skin was to be assessed by the same study physician on each visit for a particular participant. The mean change from baseline (final visit from the SD-003 study) in BSAI was assessed every 3 months. Only participants with data available for analysis at the specified time point are presented.
