Clinical Trial Summary

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).


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.

Outcome

Type Measure Description Time frame Safety issue
Primary 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. Baseline, Week 4
Secondary 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. Baseline, Days 8 and 15
Secondary 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. Week 4
Secondary 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. Week 4
Secondary 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. Week 4
Secondary 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. Baseline, Days 8 and 15, and Week 4
Secondary 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. Baseline, Days 8 and 15, and Week 4
Secondary 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. Baseline, Days 8 and 15, and Week 4
