Dupilumab Demonstrates Rapid Onset of Action in Improving Signs, Symptoms and Quality of Life in Adults with Atopic Dermatitis.

Abstract

Dupilumab has significantly improved the signs, symptoms and quality of life (QoL) of patients with moderate-to-severe atopic dermatitis (AD) in randomised, controlled clinical trials. However, there is a need to assess the effectiveness and safety of dupilumab in real-world clinical practice. The PROLEAD study was designed to examine the effectiveness and safety of dupilumab in moderate-to-severe AD in a real-world setting in Germany. Here, we present 12-week effectiveness and safety results with dupilumab from PROLEAD. PROLEAD is a multicentre, prospective, non-interventional study being conducted at 126 routine care sites across Germany. Adults with moderate-to-severe AD who require systemic therapy were treated with dupilumab as indicated by the Summary of Product Characteristics. Data collected included physician assessments (EASI, BSA, SCORAD, and IGA) and patient-reported outcomes (PROs [POEM, DLQI, EQ-5D-5L, Peak Pruritus NRS and MOS Sleep Scale]). Of 839 patients assessed for eligibility, 828 were included. The full analysis and safety analysis sets comprised 775 and 818 patients, respectively. The number of patients receiving concomitant therapy decreased from baseline to Week 12. Mean (standard deviation [SD]) percentage change in EASI score from baseline to Week 12 was -67.5% (48.4%) and was comparable across the four body regions. The proportion of patients achieving EASI-75 was 59.4% at Week 12. Mean (SD) Peak Pruritus NRS decreased from 7.4 (2.3) at baseline to 3.4 (2.6) at Week 12. Improvements from baseline to Week 12 were reported in all PROs assessed. No new safety signals were observed. Improvements in efficacy outcomes and adverse event rates in a real-world setting were more favourable than in phase 3 clinical trials. The 12-week findings of PROLEAD demonstrate that treatment with dupilumab is effective and well tolerated, with rapid onset of action in signs, symptoms and QoL in patients with moderate-to-severe AD in the realworld.
