About this study

Official title: A Phase 2a, Multicenter, Randomized, Double-blind, Vehicle-controlled, Parallel-group Study to Determine the Safety, Tolerability, Pharmacokinetics and Efficacy of ATI-1777 in Adult Patients With Moderate or Severe Atopic Dermatitis

This is a first-in-human, randomized, double-blind, parallel-group, vehicle-controlled study to evaluate the efficacy, safety, tolerability, and PK of ATI-1777 solution following twice-daily applications to target areas of participants with moderate or severe atopic dermatitis (AD).

Read the detailed description

Participants underwent screening evaluations to determine eligibility up to 30 days prior to randomization. Participants who meet all the entry criteria were randomized on Day 1 to active or vehicle treatment. Participants applied study drug (ATI-1777 topical solution 2.0% w/w or vehicle) twice daily for 4 weeks with weekly study visits and were to return 2 weeks after the last dose of study medication for a Post treatment Follow-up (PTFU) Visit.

What is being measured

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

  1. Percent Change From Baseline in Eczema Area and Severity Index (EASI) Score at Week 4

    The EASI evaluation was performed by the Principal Investigator and evaluated atopic dermatitis in each of 3 body regions (trunk [excluding groin and genitalia], upper extremities [excluding palms of hands], and lower extremities [excluding soles of feet]). The EASI scoring system uses a defined process to grade the severity of the signs of atopic dermatitis and the extent affected. EASI Scores ranged from 0-72, with higher scores indicative of more severe disease.

    Measured: Baseline, Week 4

Secondary outcomes (7)

  1. Percent Change From Baseline in EASI Score at Days 8 and 15

    The EASI evaluation is performed by the Principal Investigator and will evaluate atopic dermatitis in each of 3 body regions (trunk [excluding groin and genitalia], upper extremities [excluding palms of hands], and lower extremities [excluding soles of feet]). The EASI scoring system uses a defined process to grade the severity of the signs of atopic dermatitis and the extent affected. EASI Scores range from 0-72, with higher scores indicative of more severe disease.

    Measured: Baseline, Days 8 and 15

  2. Number of Participants Who Achieve 50% Improvement in EASI Score (EASI 50) by Week 4

    The EASI evaluation is performed by the Principal Investigator and will evaluate atopic dermatitis in each of 3 body regions (trunk [excluding groin and genitalia], upper extremities [excluding palms of hands], and lower extremities [excluding soles of feet]). The EASI scoring system uses a defined process to grade the severity of the signs of atopic dermatitis and the extent affected. EASI Scores range from 0-72, with higher scores indicative of more severe disease.

    Measured: Week 4

  3. Number of Participants Who Achieve 75% Improvement in EASI Score (EASI-75) by Week 4

    The EASI evaluation is performed by the Principal Investigator and will evaluate atopic dermatitis in each of 3 body regions (trunk [excluding groin and genitalia], upper extremities [excluding palms of hands], and lower extremities [excluding soles of feet]). The EASI scoring system uses a defined process to grade the severity of the signs of atopic dermatitis and the extent affected. EASI Scores range from 0-72, with higher scores indicative of more severe disease.

    Measured: Week 4

  4. Number of Participants Who Achieve 90% Improvement in EASI Score (EASI-90) by Week 4

    The EASI evaluation is performed by the Principal Investigator and will evaluate atopic dermatitis in each of 3 body regions (trunk [excluding groin and genitalia], upper extremities [excluding palms of hands], and lower extremities [excluding soles of feet]). The EASI scoring system uses a defined process to grade the severity of the signs of atopic dermatitis and the extent affected. EASI Scores range from 0-72, with higher scores indicative of more severe disease.

    Measured: Week 4

  5. Change From Baseline in Investigator Global Assessment (IGA) Score for Atopic Dermatitis at Days 8 and 15, and Week 4

    The IGA is a validated investigator's assessment of the average overall severity of participants' atopic dermatitis at a particular point in time. Scores ranged from 0-4, with higher scores indicative of more severe disease.

    Measured: Baseline, Days 8 and 15, and Week 4

  6. Change From Baseline in Percent of Body Surface Area (BSA) of Atopic Dermatitis at Days 8 and 15 and Week 4

    The total percentage of the participants BSA affected by atopic dermatitis was estimated by the investigator or designee using the handprint method, which estimates that the area of a participants' full handprint (fingers and thumbs together) constitutes 1% of their total BSA. Scores ranged from 0-100%, with higher scores indicative of increased percentage of atopic dermatitis on the skin.

    Measured: Baseline, Days 8 and 15, and Week 4

  7. Change From Baseline in Peak Pruritus Numerical Rating Scale (PP-NRS) Score at Days 8 and 15, and Week 4

    The PP-NRS is a single patient-reported item designed to measure peak pruritus, or 'worst' itch, over the previous 24 hours. Scores ranged from 0-10, with higher scores indicative of more severe itching.

    Measured: Baseline, Days 8 and 15, and Week 4

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing ATI-1777 in people with Atopic Dermatitis, run by Aclaris Therapeutics, Inc. at 14 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 20 inclusion and 42 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: finished, as of the sponsor's last update on 28 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 14 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?

Yes. Results are posted in the registry (first posted 28 Sep 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?

Percent Change From Baseline in Eczema Area and Severity Index (EASI) Score at Week 4 (time frame: Baseline, Week 4). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04598269, which also lists 1 linked publication.

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 28 Sep 2023.
