A Study to Evaluate Risankizumab in Adults and Adolescents With Moderate to Severe Atopic Dermatitis

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess the safety and efficacy of risankizumab for the treatment of moderate to severe atopic dermatitis (AD) in adults and adolescents.

Detailed Description
-----------------
This study includes a screening period of up to 35 days, a 16-week double-blind treatment period (Period A), and a 36-week double-blind treatment period (Period B). Participants who meet eligibility criteria will be randomized at Baseline in a 2:2:1 ratio to one of 3 treatment groups: (1) risankizumab 150 mg, (2) risankizumab 300 mg, or (3) matching placebo. Randomization will be stratified by Baseline disease severity (Validated Investigator Global Assessment scale for Atopic Dermatitis [vIGA-AD] score of moderate [3] versus severe [4]) and geographic region (Japan versus rest of world). At Week 16, participants in the placebo group will be re-randomized in a 1:1 ratio to receive either risankizumab 150 mg or 300 mg for the remainder of the study. Participants originally randomized to the risankizumab 150 mg or 300 mg arms will stay on their previously-assigned treatment through the end of the study.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants Achieving At Least a 75% Reduction From Baseline in Eczema Area and Severity Index (EASI 75) at Week 16 | EASI is a tool used to measure the extent (area) and severity of atopic eczema based on assessments of the head/neck, trunk, upper limbs and lower limbs. For each region the area score is recorded as the percentage of skin affected by eczema. For each region, the severity score is calculated as the sum of the intensity scores (scored as none [0], mild [1], moderate [2], or severe [3]) for redness (erythema, inflammation), thickness (induration, papulation, swelling - acute eczema), scratching (excoriation), and lichenification (lined skin, prurigo nodules - chronic eczema). The total EASI score for each region is calculated by multiplying the severity score by the area score, with adjustment for the proportion of the body region to the whole body. The final EASI score is the sum of the 4 region scores and ranges from 0 to 72 where higher scores represent worse disease. | Baseline and Week 16 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants Who Achieved an EASI 90 Response at Week 16 | EASI is a tool used to measure the extent (area) and severity of atopic eczema based on assessments of the head/neck, trunk, upper limbs and lower limbs.

The total EASI score for each region is calculated by multiplying the severity score by the area score, with adjustment for the proportion of the body region to the whole body. The final EASI score is the sum of the 4 region scores and ranges from 0 to 72 where higher scores represent worse disease. An EASI 90 response is defined as at least a 90% reduction (improvement) from Baseline in EASI score. | Baseline, Week 16 |
