About this study

Official title: A Phase 2 Randomized, Multicenter, Double-blind, Vehicle Controlled, 90-Day, Safety, Efficacy & Systemic Exposure Study of Trifarotene (CD5789) Cream HE1 in Adults and Adolescents With Autosomal Recessive Ichthyosis With Lamellar Scale

This is a phase 2 randomized, multi-center, double-blind, vehicle controlled, 90 day, safety, efficacy, and systemic exposure study followed by a 90 day open-label extension of trifarotene cream in adults and adolescents with autosomal recessive ichthyosis with lamellar scale.

Read the detailed description

This is a 2-cohort, multicenter study in subjects with moderate to severe LI. Adults (Cohort A) and adults and adolescents (Cohort B) will be randomized in a double-blind fashion to 1 of 2 doses of active or vehicle and treated twice weekly for 90 days. Subjects who complete the randomized, double-blind portion of the study will be eligible to enter a 90 day, open-label extension study.

Approximately 15 adults (≥18 years old) will be randomized into the first cohort of subjects (Cohort A) in a 1:1:1 ratio and treated twice weekly for up to 90 days. If no safety issues are identified, both adults and adolescents (ages 12-17 years, inclusive) will be allowed to enroll in Cohort B. Subjects in Cohort B will be randomized 1:1:1 and treated twice weekly for up to 90 days in the same manner as subjects in Cohort A.

All subjects who complete 90 days of double-blind study treatment will be eligible to enroll in a 90 open-label extension. Subjects in the open-label extension will receive active twice weekly for up to 90 days.

What is being measured

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

  1. The Percentage of Subjects in Each Treatment Group Who Experienced Successful Resolution of LI.

    The percentage of subjects in each treatment group who experienced successful resolution of LI where "success" is defined as clear/almost clear on treated areas and at least a 2-grade change from Baseline at Day 90/end-of-treatment (EOT) in the Double-blind Period on the 5-point IGA full body scale.

    Measured: 90 Days

Secondary outcomes (6)
  1. Total 16-point Visual Index for Ichthyosis Severity (VIIS)

    5-point Visual Index for Ichthyosis Severity (VIIS) for scaling (overall 16 points) for scaling, i.e. 0-4 points for 4 body areas: chest/abdomen, back, arms and legs) where minimum is 0 and maximum is 16 (e.g. 4 points for each of the four body parts).

    0 (Clear) No scaling

    1. (Almost Clear) Very fine, non-coalescent scales
    2. (Mild) Small and thin, non-coalescent scales
    3. (Moderate) Large and rather thick scales starting to coalesce
    4. (Severe) Very large, adherent, coalescent and very thick scales

    Measured: 90 Days

  2. The Difference in Mean Scores Using Individual Score for Roughness

    The amount of roughness of the skin will be measured on a 5-point scale. 0 (Clear) Smooth skin

    1. (Almost Clear) Hardly palpably roughness
    2. (Mild) Mild roughness (fine sand paper-like)
    3. (Moderate) Moderate, coarse roughness (coarse sand paper-like)
    4. (Severe) Very coarse skin (broken cornflakes-like)

    Measured: 90 Days

  3. The Difference in Mean Scores Using Palm Sole Assessment

    Thickening of the skin on the palms and soles will be measured on a 5-point scale:

    0 (Clear) No thickening, no roughness, no fissure

    1. (Almost Clear) Only slight thickening, minimal to no roughness, no fissures
    2. (Mild) Some thickening, mild roughness on palpation, few fissures may be present
    3. (Moderate) Substantial and diffuse thickening, coarse roughness on palpation may be present, fissures may be present
    4. (Severe) Very thickened and rough skin, numerous fissures

    Measured: 90 Days

  4. The Difference in Proportion of Subjects With Presence of Fissures on Palms Between the Active and Vehicle Groups

    Fissuring will be assessed by recording the presence or absence of fissures, the number of fissures present, and the pain associated with each fissure. The subject will assess pain associated with fissures as ranging from 0-3 (none, mild, moderate, severe) at day 90 between the active trifarotene cream HE1 and vehicle groups

    Measured: 90 Days

  5. Quality of Life Measurement Per Dermatology Life Quality Index (DLQI)

    The DLQI, or the Dermatology Quality of Life Index, is a dermatology-specific Quality of Life instrument. It is a simple 10-question validated questionnaire with 6 domains (symptoms and feelings, daily activities, leisure, work and school, personal relationships, and treatment); higher scores indicate poorer quality of life. Responses collected are on a scale of 0-3 depending on the question relevance to the subject.

    Response (Score) Very much (scored 3) A lot (scored 2) A little (scored 1) Not at all (scored 0) Not relevant (scored 0) A minimum score of 0 and maximum score of 30 is obtained by summing the score of each question. The higher the score, the more quality of life is impaired.

    0-1 = no effect at all on patient's life 2-5 = small effect on patient's life 6-10 = moderate effect on patient's life 11-20 = very large effect on patient's life 21-30 = extremely large effect on patient's life

    Measured: 90 Days

  6. The Difference in Proportion of Subjects With Presence of Fissures on Soles Between the Active and Vehicle Groups

    Fissuring will be assessed by recording the presence or absence of fissures, the number of fissures present, and the pain associated with each fissure. The subject will assess pain associated with fissures as ranging from 0-3 (none, mild, moderate, severe) at day 90 between the active trifarotene cream HE1 and vehicle groups

    Measured: 90 Days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing CD5789 Cream 200 µg/g and CD5789 Cream 100 µg/g in people with Lamellar Ichthyosis, run by Mayne Pharma International Pty Ltd at 36 sites in 9 countries.

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 0 inclusion and 25 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 14 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 36 sites in United States, Ukraine, Germany, Spain, Australia and 4 more countries. 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?

Yes. Results are posted in the registry (first posted 14 Aug 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

The Percentage of Subjects in Each Treatment Group Who Experienced Successful Resolution of LI. (time frame: 90 Days). 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 14 Aug 2023; AzTrials last refreshed its copy on 7 Nov 2026.
