Patient-Reported Symptoms and Disease Impacts in Adults With Moderate-to-Severe Atopic Dermatitis: Results From a Phase 2b Study With Abrocitinib.

Background: Moderate-to-severe atopic dermatitis (AD) is inadequately controlled with current treatments for many patients. Abrocitinib is an oral Janus kinase 1 selective inhibitor under investigation for the treatment of AD.

Objective: The aim of the study was to evaluate patient-reported outcomes in a phase 2b study of abrocitinib in adults with moderate-to-severe AD inadequately controlled by topical therapy (NCT02780167).

Methods: Patients (N = 267) were randomly assigned 1:1:1:1:1 to 12-week, once-daily abrocitinib (200, 100, 30, 10 mg) or placebo. Patient-reported outcomes included pruritus numeric rating scale (average), Patient Global Assessment, Patient-Oriented Eczema Measure, Pruritus and Symptoms Assessment for AD, Dermatology Life Quality Index, and Hospital Anxiety and Depression Scale (HADS).

Results: Abrocitinib 200 or 100 mg resulted in significantly greater improvements from baseline versus placebo in peak pruritus numeric rating scale (by days 2 and 3, respectively), Patient-Oriented Eczema Measure, Pruritus and Symptoms Assessment for AD, Dermatology Life Quality Index, and HADS (200 mg only, by week 1 or 2), and proportions of the patients with Patient Global Assessment clear/almost clear with 2-point or greater improvement (by weeks 1 and 4, respectively) that continued through week 12 (except HADS).

Conclusions: Abrocitinib treatment resulted in rapid (2 days to 2 weeks) and persistent improvements in AD symptoms and impacts in moderate-to-severe disease.
