Researchers are evaluating the safety and effectiveness of upadacitinib in treating adults and adolescents with moderate to severe hidradenitis suppurativa (HS) who have not responded to or cannot tolerate anti-tumor necrosis factor (TNF) therapy. HS is an inflammatory skin disease causing painful lesions in areas such as the underarms, groin, and anal/genital regions. This phase 3, double-blind study involves approximately 1328 participants worldwide and aims to monitor disease activity and adverse events over time. Participants will receive oral tablets of either upadacitinib or placebo once daily during Period 1 and Period 2, lasting a total of 36 weeks. In Period 1, participants are randomly assigned to one of two treatment groups, with a 50% chance of receiving placebo. Based on results and placement in earlier periods, participants enter Period 2 with six potential treatment groups. Eligible participants from these periods may continue into Period 3, a long-term extension lasting 68 weeks, continuing the same daily oral treatment. Following the treatment periods, participants will be followed for approximately 30 days. During the study, participants will attend regular outpatient visits for medical assessments, monitoring for side effects, and completing questionnaires. Researchers will measure the percentage of participants achieving a clinical response called HiSCR 50 from baseline to week 16 and track adverse events up to approximately week 108. The study may require a higher treatment commitment compared to usual care, but provides close monitoring of disease activity and safety throughout all study phases.
