Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by eczematous morphology and intense pruritus. Previous clinical trials have demonstrated that upadacitinib (UPA) was superior to placebo (PBO) in the treatment of moderate-to-severe AD. Here, we analyse the efficacy and safety of UPA across 52 weeks in adolescent and adult subgroups from three phase 3 studies. Patients were randomized to UPA 15 mg (UPA15), UPA 30 mg (UPA30) or PBO orally once daily, either alone or with concomitant topical corticosteroids. After 16 weeks, patients in the PBO group were randomized to the UPA15 or UPA30 groups. For both adolescent and adult subgroups at 52 weeks, the proportion of responders in the UPA15 and UPA30 groups was: ≥70% and 83% for EASI75, ≥31% and 47% for vIGA-AD 0/1 and ≥37% and 61% for Worst Pruritus Numeric Rating Scale improvement ≥4. Children’s Dermatology Life Quality Index (CDLQI) 0/1 was achieved by ≥15% (UPA15) and ≥28% (UPA30) of adolescents aged 12 to <16 years; DLQI 0/1 was achieved by ≥18% (UPA15) and ≥38% (UPA30) of adolescents aged 16 to <18 years and ≥30% (UPA15) and ≥45% (UPA30) of adults. Hospital Anxiety and Depression Scale (HADS-A and HADS-D) <8 was achieved in ≥28% of adolescents and ≥45% of adults for both treatment groups. Rates of serious adverse events (AEs) and serious AEs leading to discontinuation at week 52 were similar for both adolescents and adults. UPA15 and UPA30 responses in moderate-to-severe AD across 52 weeks were similar between adolescents and adults, with acceptable safety outcomes in both populations.
