A Study to Evaluate Adverse Events and Change in Disease Activity Comparing Oral Upadacitinib to Subcutaneous Dupilumab in Adolescent and Adult Participants With Moderate to Severe Atopic Dermatitis
- Registration Number
- NCT05601882
- Lead Sponsor
- AbbVie
- Brief Summary
Atopic dermatitis (AD) is a skin condition that may cause a rash and itching due to inflammation of the skin. Therapies spread over the skin may not be enough to control the AD in trial participants who require systemic anti-inflammatory treatment. This study compares upadacitinib to dupilumab in adolescent and adult participants with moderate to severe AD who have inadequate response to systemic therapies. Adverse events and change in the disease activity will be assessed.
Upadacitinib and dupilumab are approved drugs for the treatment of moderate to severe atopic dermatitis (AD). The study is comprised of a 35-day Screening Period, a 16-week treatment Period 1 and a 16-week treatment Period 2. Participants are randomly assigned to 1 of 2 groups called treatment arms to receive upadacitinib Dose A or dupilumab in Period 1. There is a 30-day or 12-week follow-up visit for those on upadacitinib or dupilumab respectively, who will not enter Period 2. In Period 2, participants will receive upadacitinib Dose A or Dose B for 16 weeks, followed by a 30-day follow-up visit. Approximately 880 adolescent and adult participants ages 12 to 64 with moderate to severe AD who are candidates for systemic therapy will be enrolled at up to 330 sites worldwide.
There may be higher treatment burden for participants in this trial compared to their standard of care . Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

Group Intervention Description Dupilumab (Period 1) Dupilumab Adult participants received a loading dose of 600 mg dupilumab by subcutaneous (SC) injection at the Baseline visit followed by 300 mg dupilumab SC every other week (EOW) until Week 16. Adolescents (12 to 17 years of age and weighing at least 40 kg) received treatment according to their body weight. Participants weighing 40 to \< 60 kg received a loading dose of 400 mg dupilumab SC at the Baseline visit followed by 200 mg SC EOW until Week 16. Those weighing 60 kg or more received a loading dose of 600 mg dupilumab SC at the Baseline visit followed by 300 mg dupilumab SC EOW until Week 16. Upadacitinib (Period 1) Upadacitinib Participants received 15 mg upadacitinib orally once a day (QD) up to Week 16. Starting at Week 4, participants had their dose increased to 30 mg QD if they had a \< 50% reduction from Baseline in Eczema Area and Severity Index (EASI 50) response or a \< 4-point improvement from Baseline in Worst Pruritus Numerical Rating Scale (WP-NRS; weekly average). Starting at Week 8, participants had their dose increased to 30 mg QD if they had a \< EASI 75 response. Dupilumab -> Upadacitinib (Period 2) Upadacitinib At Week 16, participants receiving dupilumab as per its label in Period 1 were reassigned based on their Eczema Area and Severity Index (EASI) response. Those with \< EASI 75 were offered the option to receive oral doses of upadacitinib 15 mg QD in Period 2 up to Week 32. Those with ≥ EASI 75 completed the end of study procedures. Starting at Week 20, participants with \< EASI 75 or a \< 4-point improvement from Baseline in Worst Pruritus Numerical Rating Scale (WP-NRS; weekly average) had their dose increased to 30 mg QD up to Week 32. Upadacitinib -> Upadacitinib 30 mg (Period 2) Upadacitinib At Week 16, participants receiving upadacitinib in Period 1 were reassigned based on their Eczema Area and Severity Index (EASI) response. Those with \< EASI 75 were allocated or continued to receive upadacitinib 30 mg QD in Period 2. Those with ≥ EASI 75 completed the end of study procedures.
- Primary Outcome Measures
Name Time Method Percentage of Participants Achieving a ≥ 90% Reduction From Baseline in Eczema Area and Severity Index Score (EASI 90) and Worst Pruritus Numerical Rating Scale of 0 or 1 (WP-NRS 0/1) at Week 16 Baseline and Week 16 The EASI is a composite index with scores ranging from 0 to 72. Four AD disease characteristics (erythema, thickness \[induration, papulation, edema\], scratching \[excoriation\], and lichenification) assessed for severity on a scale of "0" (absent) through "3" (severe). In addition, the area of AD involvement is assessed as a percentage by body area of head, trunk (including the genital area), upper extremities, and lower extremities (including the buttocks), and converted to a score of 0 to 6. In each body region, the area is expressed as 0, 1 (1% to 9%), 2 (10% to 29%), 3 (30% to 49%), 4 (50% to 69%), 5 (70% to 89%), or 6 (90% to 100%).
The Worst Pruritus NRS is an assessment tool that participants used to report the intensity of their pruritus during a 24-hour recall period using an electronic hand-held device. Participants rated itch (pruritus) intensity at its worst during the past 24 hours on an 11-point scale from 0 (no itch) to 10 (worst imaginable itch).
