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

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.

The CDLQI is a 10-item, validated questionnaire used to assess the impact of AD disease symptoms and treatment on QoL. The CDLQI has been validated for use in individuals 4-16 years old. It consists of 10 questions assessing impact of skin diseases on different aspects of a patient's QoL over the prior week. The CDLQI items include symptoms and feelings, daily activities, leisure, school, relationships, sleep, and treatment. Each item is scored on a 4-point scale (0 = not at all; 1 = only a little; 2 = quite a lot; and 3 = very much). Item scores (0 to 3) are added to provide a total score range of 0 to 30; higher scores indicate greater impairment of QoL. A negative change from Baseline indicates improvement. In this study, the CDLQI was administered to participants who were \< 16 years old at the Baseline visit.

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. EASI 50 response is defined as at least a 50% reduction (improvement) from Baseline in EASI score.
