Brief summary
This study will evaluate upadacitinib compared to dupilumab (Dupixent®) in adults with moderate to severe atopic dermatitis (AD) who are candidates for systemic therapy.
Detailed description
The study is comprised of a 35-day screening period, a 24-week double-blinded treatment period, and a follow-up visit 12 weeks after the last dose. Participants who complete Week 24 have the option to enroll into an open-label study (Study M19-850; NCT04195698) of upadacitinib 30 mg once daily and receive treatment with upadacitinib for an additional 52 weeks. Participants who meet eligibility criteria will be randomized in a 1:1 ratio to receive either upadacitinib or dupilumab. 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 age (\<40, ≥ 40 to \< 65, ≥ 65 years).

| Percentage of Participants Achieving a 75% Reduction From Baseline in Eczema Area and Severity Index Score (EASI 75) at Week 16 | Baseline and 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. |
