Clinical Trial Summary

The objective of this study is to compare the efficacy and safety of RGN-137 topical gel with that of placebo gel for treatment of junctional epidermolysis bullosa (JEB) or dystrophic epidermolysis bullosa (DEB).

Description:

RGN-137 will be evaluated for efficacy and safety compared to a Placebo. A matched-pair design will be used to evaluate RGN-137 treatment versus placebo for treatment of 15 subjects with JEB or DEB. Eligible subject must have 1 set of matched-pair wound. The investigator will assign pair of index wounds, each wound with an area between 5cm2 and 50cm2, inclusive, for the eligible subject on Day 1, and for each pair, one wound will be randomized to receive RGN-137 gel and the other to receive Placebo gel. Subjects and independent evaluator will be blinded to the treatment assignments for each wound.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Index wound characteristics at the scheduled visits.	(inflammation/erythema, induration, crusting, exudate, cellulitis, and other abnormalities)	up to Day 84
Primary	Time to achieving 50% reduction in area of each index wound from Day 1 up to Day 84.	This primary endpoint will the time to achieving 50% reduction in area of each index wound from Day 1 up to Day 84, defined as date of the first study visit on which 50% reduction in index wound area is achieved minus date of Day 1 visit.	up to Day 84
Secondary	Time to achieving 50%, 75%, and 100% (with drainage or without drainage) reduction in area of each index wound from Day 1 up to Day 84.	This secondary endpoint will the time to achieving 50%, 75%, and 100% reduction in area of each index wound from Day 1 up to Day 84, defined as date of the first study visit on which 50% reduction in index wound area is achieved minus date of Day 1 visit.	up to Day 84
Secondary	Incidence of 50%, 75%, and 100% reduction and complete re-epithelialization without drainage in area of each index wound at the scheduled visits.	This secondary endpoint will be summarized by treatment using frequency counts and percentages.	up to Day 84
Secondary	Change from Baseline and percent change from Baseline in surface area of each index wound at the scheduled visits.	This secondary endpoint will be computed for each treatment group as well as for treatment difference at each visit.	up to Day 84
