Efficacy and Safety Study to Evaluate SD-101 in Epidermolysis Bullosa

September 3, 2026 updated by: Paradigm Therapeutics

A Phase 3, Multi-center, Randomized, Double-Blind, Placebo Controlled Study of the Efficacy and Safety of SD-101 Cream in Patients With Epidermolysis Bullosa

The upcoming trial is for EB patients is a topically applied whole-body treatment of patients with either Simplex, RDEB or Junctional (nH) ages 1 month to 12 years old at study entry. There are only 4 site visits by patients with minimal assessments over a 2-month period, and patients completing this study will have the ability to continue receiving SD-101-6.0 at home in an open-label extension study. The drug product and placebo require no special preparation or storage conditions (room temperature).

Detailed Description

This is a Phase 3, multi-center, randomized, double-blind, placebo-controlled, study to compare the efficacy and safety of SD-101-6.0 cream vs. placebo (SD 101-0.0) on wounds in patients with Simplex, Recessive Dystrophic, or Junctional non-Herlitz (JEB-nH) EB.

SD-101-6.0 cream or placebo (SD-101-0.0) will be applied topically, once a day to the entire body for a period of 60 days. Enrolled patients will have 1 target wound selected at baseline. The selected target wound must be at least 21 days old (size 10 to 50 cm2). Photographic confirmation of the target wound location will be collected at baseline, and the picture saved from the first visit will be used to confirm location of the target wound at subsequent visits. The patient will return to the study site for Visit 2 (14 days ±7 days from baseline), Visit 3 (30 days ±7 days from baseline), and Visit 4 (60 days ±7 days from baseline) to have the target wound re-assessed for the level of healing. Once the target wound is healed, it will be considered healed at subsequent visits and no further re-assessment of the target wound will be conducted The ARANZ SilhouetteStar™ will be used to measure the target wound at all visits until the target wound is documented as closed. Assessment of itching will be evaluated at each visit. In addition, body surface area (BSA), and other secondary endpoints will be evaluated at the baseline and Month 2 visits.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Informed Consent (ICF) form signed by the patient or patient's legal representative. Since all patients with be 12 years old or younger at study entry, signed assent from the patient's legal representative will be required.
  2. Patient (or caretaker) must be willing to comply with all protocol requirements.
  3. Diagnosis of Simplex, Recessive Dystrophic, or JEB-nH (intermediate) EB.
  4. Patient must have 1 target wound (size 10 to 50 cm2).
  5. Patients must be between 28 days to 12 years at study entry

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Target wound closure
Time Frame: 1 month
The primary endpoint is the proportion of patients in each treatment group who experience complete closure of their target wound by Month 1 on study. Complete target wound closure is defined as skin re-epithelialization without drainage.
1 month

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in wound burden
Time Frame: 2 months
Change in wound burden based on BSA measurements at Month 2, compared to Baseline.
2 months
Change in itching
Time Frame: 2 months
The Itch Man Pruritus Assessment Tool, which is a validated 5-point Likert scale that goes from 0 to 4, where 0 is comfortable and 4 is the most terrible. The scale is used to assess itching at Week 1 (Days 1-7), Week 2, Month 1 and Month 2, compared to Baseline.
