Study of Upadacitinib and Dupilumab in Adults Aged 18 to 63 With Moderate to Severe Atopic Dermatitis Not Responding to Dupilumab

What this Trial Is About

This research aims to evaluate the effectiveness and safety of upadacitinib at different doses for adults with moderate to severe atopic dermatitis AD who have not responded well to dupilumab treatment. AD is a skin condition causing rash and itching due to inflammation. The study includes approximately 200 adults aged 18 to less than 64 years, all current dupilumab users with a history of inadequate response. The trial is conducted in two periods to compare upadacitinib 15mg to dupilumab 300mg and adjust doses based on clinical response. In Period 1, participants are randomly assigned to receive either upadacitinib 15mg tablets once daily or dupilumab 300mg subcutaneous injections every two weeks for eight weeks. Participants on upadacitinib 15mg may have their dose increased to 30mg after two weeks depending on response. Period 2 lasts 24 weeks, during which participants continue or adjust doses based on their Eczema Area and Severity Index EASI response at Week 8. Participants may remain on their assigned dose or switch doses accordingly. Participants attend regular visits at hospitals or clinics during the 35-day screening, 8-week Period 1, and 24-week Period 2, plus a 30-day follow-up. Assessments include medical exams, blood tests, monitoring for side effects, and questionnaires. Researchers measure outcomes such as the percentage achieving at least a 90% reduction in eczema severity EASI 90 at Week 8. The study monitors treatment effects and safety carefully throughout the 32-week treatment and follow-up period.
