Supplementary Material for: Abrocitinib Provides Rapid and Sustained Improvement in Skin Pain and Is Associated With Improved Quality of Life Outcomes in Adult and Adolescent Patients With Moderate-to-Severe Atopic Dermatitis

Background: Skin pain in atopic dermatitis (AD) increases with disease severity and is associated with substantial quality of life (QoL) burden. Objectives: To evaluate abrocitinib efficacy on skin pain and QoL in adults and adolescents with moderate-to-severe AD. Methods: This post hoc analysis included data with abrocitinib administered as monotherapy (pooled phase 2b [NCT02780167] and phase 3 JADE MONO-1 [NCT03349060] and MONO-2 [NCT03575871]) or in combination with topical therapy (phase 3 JADE COMPARE [NCT03720470] and JADE TEEN [NCT03796676]). Patients received oral, once-daily abrocitinib 200 mg, abrocitinib 100 mg, or placebo for 12 or 16 weeks (JADE COMPARE). Skin pain was rated using the Pruritus and Symptoms Assessment for Atopic Dermatitis (PSAAD) skin pain Numerical Rating Scale (NRS) item (“How painful was your skin over the past 24 hours?”) on a scale from 0 (not painful) to 10 (extremely painful). Itch (Peak Pruritus NRS) and QoL (Dermatology Life Quality Index or Children’s Dermatology Life Quality Index) were assessed. Least squares mean (LSM) change from baseline was analyzed using mixed effects repeated measures modeling. Results: A total of 1822 patients (monotherapy pool, n=942; JADE COMPARE, n=595; JADE TEEN; n=285) were analyzed. LSM change from baseline in PSAAD skin pain score was significantly greater with abrocitinib versus placebo from week 2 through week 12 or 16 across all 3 study populations and occurred in a dose-dependent manner. A greater proportion of patients achieved a ≥4-point improvement from baseline in PSAAD skin pain score with abrocitinib (200 mg and 100 mg) versus placebo in the monotherapy pool (56% and 38% vs 12%; week 12), JADE COMPARE (72% and 52% vs 26%; week 16), and JADE TEEN (51% and 60% vs 31%; week 12). Additionally, a greater proportion of patients achieved a stringent threshold of skin pain improvement (PSAAD skin pain score
