About this study

Official title: A Randomized,Single-Blind, Placebo-controlled, Self-matched Pairing, Independent Evaluated Study to Evaluate the Efficacy and Safety of RGN-137 Topical Gel in Subjects With Junctional and Dystrophic Epidermolysis Bullosa (CELEB)

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).

Read the 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.

    Also called Dermal Topical Gel

    It will be applied topically to the appropriate wound once a day for up to 84 days.

  • PlaceboDrug

    Also called Vehicle Control

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: up to Day 84

Secondary outcomes (3)
  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.

    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.

    Measured: up to Day 84

  2. 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.

    Measured: up to Day 84

  3. 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.

    Measured: up to Day 84

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing RGN-137 in people with Junctional Epidermolysis Bullosa and Dystrophic Epidermolysis Bullosa, run by Lenus Therapeutics, LLC at 5 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 22 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Business Decision). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Time to achieving 50% reduction in area of each index wound from Day 1 up to Day 84. (time frame: up to Day 84). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Aug 2022.
