BACKGROUND: Abrocitinib improved signs and symptoms of moderate-to-severe atopic dermatitis (AD) at 12/16 weeks in phase 3 studies with a manageable safety profile. Further understanding of the abrocitinib long-term efficacy and safety profile is important for its appropriate use in treating chronic AD. OBJECTIVE: To evaluate the abrocitinib efficacy up to 48 weeks and long-term safety in patients with moderate-to-severe AD. METHODS: JADE EXTEND (NCT03422822) is an ongoing phase 3 long-term extension study that enrolled patients from previous abrocitinib AD trials. This analysis focuses on patients from phase 3 JADE MONO-1 (NCT03349060), JADE MONO-2 (NCT03575871) and JADE COMPARE (NCT03720470) who completed the full treatment period of placebo or abrocitinib (200 mg or 100 mg once-daily) and subsequently entered JADE EXTEND. Efficacy endpoints included proportion of patients achieving skin clearance (Investigator's Global Assessment [IGA] 0/1 [clear/almost clear]; ≥75% improvement in Eczema Area and Severity Index [EASI-75]) and itch response (Peak Pruritus Numerical Rating Scale [PP-NRS] severity ≥4-point improvement). Safety endpoints included treatment-emergent adverse events (TEAEs), serious TEAEs and TEAEs leading to discontinuation. Data cutoff: April 22, 2020. RESULTS: As of the data cutoff, ~70% and ~45% of patients received abrocitinib for ≥36 and ≥48 weeks, respectively. Nasopharyngitis, atopic dermatitis, nausea, and upper respiratory tract infections were the most frequent TEAEs. Serious TEAEs occurred in 7% and 5% and TEAEs leading to study discontinuation occurred in 9% and 7% of patients receiving abrocitinib 200 mg and 100 mg, respectively. Week 48 efficacy responses with abrocitinib 200 mg and 100 mg were: IGA 0/1 52% and 39%; EASI-75 82% and 67%, and PP-NRS severity ≥4-point improvement 68% and 51%. CONCLUSIONS: In patients with moderate-to-severe AD, long-term abrocitinib treatment resulted in clinically meaningful skin and pruritus improvement. The long-term safety profile was manageable and consistent with previous reports.
