Study Details

Study Description

Brief 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).

Condition or Disease Intervention/Treatment Phase
Phase 2

Detailed 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.

Arms and Interventions

Arm Intervention/Treatment
Experimental: RGN-137

It is formulated as a gel for topical administration.

Drug: RGN-137
It will be applied topically to the appropriate wound once a day for up to 84 days.
Other Names:
  • Dermal Topical Gel
  • Placebo Comparator: Placebo

    It is composed of the same excipients as RGN-137 formulation without the active ingredient.

    Drug: Placebo
    It will be applied topically to the appropriate wound once a day for up to 84 days.
    Other Names:
  • Vehicle Control
  • Outcome Measures

    Primary Outcome Measures

    1. Time to achieving 50% reduction in area of each index wound from Day 1 up to Day 84. [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.

    Secondary Outcome Measures

    1. 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. [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.

    2. Incidence of 50%, 75%, and 100% reduction and complete re-epithelialization without drainage in area of each index wound at the scheduled visits. [up to Day 84]

      This secondary endpoint will be summarized by treatment using frequency counts and percentages.

    3. Change from Baseline and percent change from Baseline in surface area of each index wound at the scheduled visits. [up to Day 84]

      This secondary endpoint will be computed for each treatment group as well as for treatment difference at each visit.

    Other Outcome Measures

    1. Index wound characteristics at the scheduled visits. [up to Day 84]

      (inflammation/erythema, induration, crusting, exudate, cellulitis, and other abnormalities)
