CRANBURY, N.J., May 19, 2017 (GLOBE NEWSWIRE) — Amicus Therapeutics, Inc. (Nasdaq:FOLD), has completed the analysis plan for the primary endpoints in the blinded ongoing Phase 3 clinical study (ESSENCE) of the novel topical medicine SD-101 for epidermolysis bullosa (EB). SD-101 was one of the first treatments to receive the FDA’s Breakthrough Therapy designation. ESSENCE is a double-blind, placebo-controlled registration study that completed enrollment of more than 160 patients who have a documented diagnosis of Simplex, Recessive Dystrophic, or Junctional non-Herlitz EB.
Based on discussions and written communication from the Dermatology Division of the U.S. Food and Drug Administration, Amicus will analyze the primary endpoints for the Phase 3 ESSENCE study as follows:
- The endpoint of “time to wound closure within 3 months” will be analyzed first. If the difference between SD-101 6% and placebo is statistically significant (p ≤ 0.05), then the study will be considered a success.
- If the first endpoint is statistically significant, then “proportion of patients with target wound closure at month 3” will be analyzed and considered statistically significant at p ≤ 0.05.
Time to Wound Closure is a clinically relevant endpoint in EB, given the constant and often chronic nature of EB wounds. Time to Wound Closure is as an acceptable efficacy endpoint for wound-related diseases, per FDA guidance.1
Jay Barth, MD, Chief Medical Officer of Amicus Therapeutics, Inc. stated, “We believe that the planned analysis of the primary endpoints increases our overall likelihood for success in the Phase 3 ESSENCE study of SD-101 for epidermolysis bullosa. Time to Wound Closure accounts for wound healing across all study time points, offering greater precision for discriminating treatment effects and treatment differences between SD-101 and placebo. We have been very pleased with the collaborative interactions with the Dermatology Division of the FDA under our breakthrough therapy designation for SD-101. We look forward to announcing data from this study.”
Amicus is on track to report top-line data from the ESSENCE study during the third quarter of 2017. To date, more than 95 percent of patients completing the 3-month primary treatment period have elected to continue in the open-label extension study.
About Epidermolysis Bullosa (EB)
EB is a rare, genetic disorder that manifests as blistering or erosion of the skin, and, in some cases, the epithelial lining of other organs. EB is chronic, potentially disfiguring, and in some cases fatal. Patients with EB have painful wounds and blisters that can lead to infection and scarring. There are many genetic and symptomatic variations of EB, but all forms share the common symptom of fragile skin that blisters and tears, sometimes from the slightest friction or trauma. There is currently no approved treatment for EB. Current standard of care consists of pain management and the bandaging and cleaning of open wounds to prevent infection.
