Atopic dermatitis is a chronic immune-inflammatory skin disease that significantly impairs quality of life, with itch representing a key, but not exclusive, contributor to this burden.We aimed to evaluate itch relief and quality-of-life improvements with abrocitinib or dupilumab for 16 weeks alongside topical therapy in patients with moderate-to-severe atopic dermatitis.This post hoc analysis included pooled data from patients who received abrocitinib (200 mg/day) or dupilumab (300 mg/every 2 weeks) in phase III JADE COMPARE and JADE DARE. Assessments included proportions of patients achieving a ≥ 4-point improvement from baseline in Peak Pruritus Numerical Rating Scale (PP-NRS4), itch-free state (PP-NRS 0/1) by baseline itch severity, and proportions of patients with residual itch achieving Dermatology Life Quality Index score of 0/1 (DLQI 0/1), total Patient-Oriented Eczema Measure (POEM) score ≤ 2, SCORing Atopic Dermatitis (SCORAD) sleep loss visual analog scale score of 0/1 (SCORAD sleep loss visual analog scale 0/1), and POEM sleep item score of 0 (POEM sleep 0).Among 1196 patients (abrocitinib, n = 588; dupilumab, n = 608), those with greater baseline itch severity experienced greater atopic dermatitis severity and worse quality of life than patients with less severe itch. At week 16, numerically more patients achieved PP-NRS4 (67% vs 63%) and PP-NRS 0/1 (36% vs 27%) with abrocitinib versus dupilumab, respectively, regardless of baseline itch severity, although 95% confidence intervals overlapped for both measures. Median time to achieve PP-NRS4 (11 vs 29 days) and PP-NRS 0/1 (57 vs 139 days) was shorter with abrocitinib versus dupilumab, respectively. Numerically greater proportions of patients achieving PP-NRS 0/1 also achieved DLQI 0/1, POEM ≤ 2, SCORAD sleep loss visual analog scale 0/1, or POEM sleep 0 than patients with residual itch (PP-NRS ≥ 2).In this post hoc pooled analysis of the JADE COMPARE and JADE DARE trials, the proportion of patients with moderate-to-severe atopic dermatitis achieving clinically meaningful itch responses, including an itch-free state, was generally higher with abrocitinib compared with dupilumab. Median time to achievement of both PP-NRS4 and an itch-free state was shorter with abrocitinib than with dupilumab. Patients who achieved an itch-free state experienced greater improvements in quality of life and sleep compared with patients with residual itch.JADE COMPARE (NCT03720470; registration date: 2018/10/24); JADE DARE (NCT04345367; registration date: 2020/04/10).
