Complete/Near-Complete Itch Response Observed in Patients with Moderate-to-Severe Atopic Dermatitis Initiating...

Atopic dermatitis (AD) is a chronic, relapsing disease that can start at any age and has a significant negative impact on quality of life, including a significant itch burden. Here we report the proportion of patients in a real-world study achieving a complete/almost complete resolution of itch, as measured by the Peak Pruritus Numeric Rating Scale (PP-NRS) and improvement in overall disease severity score (ODS), in patients aged ≥ 12 years with moderate-to-severe AD up to 3 years after commencing dupilumab treatment.

PROSE is an ongoing, prospective, observational, multicenter registry in the USA and Canada, collecting real-world data from patients aged ≥ 12 years with moderate-to-severe AD who initiated dupilumab in accordance with country-specific prescribing information. Assessments include patient-reported PP-NRS (range 0-10) and clinician-measured ODS score (range 0-4).

A total of 857 patients were enrolled, of whom 42% were male and 6.4% were adolescents aged ≥ 12 to < 18 years. The mean [standard deviation (SD)] age was 40.1 (17.9) years, and the duration of AD was 17.4 (16.2) years. The subsequent mean (SD) duration of dupilumab treatment was 23.1 (13.7) months. The proportion of patients achieving complete/almost complete itch resolution (PP-NRS score of 0 or 1) improved consistently over time, from 2.7% (17/622) of patients at baseline to 56.3% (58/103) at 3 years. Additionally, by year 3, 65.1% (54/83) of patients had an ODS score of no/minimal disease (score of 0 or 1), versus 2.2% (19/852) at baseline.

In this real-world setting of the PROSE registry, adult and adolescent patients with moderate-to-severe AD followed up for up to 3 years after the initiation of dupilumab treatment experienced sustained and substantial improvement in pruritus and ODS, using the stringent endpoints of PP-NRS 0 or 1 and ODS 0 or 1.
