    Abstract:
    BACKGROUND: Moderate to severe atopic dermatitis (AD) is associated with substantial patient burden despite current therapies. OBJECTIVE: We sought to evaluate dupilumab treatment on patient-reported outcomes in adults with moderate to severe AD. METHODS: Adults (N = 380) with moderate to severe AD inadequately controlled by topical medications were randomized to 16 weeks of double-blind, subcutaneous treatment with dupilumab 100 mg every 4 weeks, 200 mg every 2 weeks, 300 mg every 2 weeks, 300 mg once weekly, or placebo. Patient-reported outcomes included pruritus numeric rating scale; patient-reported sleep item on Scoring AD scale; Patient-Oriented Eczema Measure; Hospital Anxiety and Depression Scale; Dermatology Life Quality Index; and 5-dimension 3-level EuroQol. RESULTS: Dupilumab reduced peak itch at 16 weeks relative to placebo by 1.1 to 3.2 points on numeric rating scale (P < .0001 all doses, except 100 mg every 4 weeks P < .05); improved sleep and health-related quality of life on Dermatology Life Quality Index and 5-dimension 3-level EuroQol (P < .05 all doses, except 100 mg every 4 weeks); and reduced anxiety and depression symptoms (P < .05 all doses). Dupilumab's effects appeared early and achieved clinically relevant improvements without significant safety concerns. LIMITATIONS: There are potential cultural differences affecting patient-reported outcome responses. Outcomes were secondary or exploratory end points. CONCLUSION: Dupilumab produced early and sustained patient-reported and clinically relevant improvements in sleep, mental health, and health-related quality of life; the two 300-mg dose regimens resulted in greatest benefits.
