Dupilumab Improves Symptoms of Anxiety and Depression in Adults and Adolescents With Moderate-to-Severe Atopic Dermatitis: A Post Hoc Analysis of Three Phase 3 Trials (LIBERTY AD SOLO 1 & 2 and ADOL)

Which Clinical Measurement Tools for Atopic Dermatitis Severity Make the Most Sense in Clinical Practice?

Assessment of atopic dermatitis (AD) severity is essential for therapeutic decision making and monitoring treatment progress. However, there are a myriad of clinical measurement tools available, some of which are impractical for routine clinical use despite being recommended for clinical trials in AD. For measurement tools to be used in clinical practice, they should be valid, reliable, rapidly completed, and scored, and easily incorporated into existing clinic workflows. This narrative review addresses content, validity, and feasibility, and provides a simplified repertoire of assessments for clinical assessment of AD based on prior evidence and expert opinion. Tools that may be feasible for clinical practice include patient-reported outcomes (eg, dermatology life quality index, patient-oriented eczema measure, numerical rating scales for itch, pain, and sleep disturbance, AD Control Tool, and patient-reported global assessment), and clinician-reported outcomes (eg, body surface area and investigator's global assessment). AD is associated with variable clinical signs, symptoms, extent of lesions, longitudinal course, comorbidities, and impacts. Any single domain is insufficient to holistically characterize AD severity, select therapy, or monitor treatment response. A combination of these tools is recommended to balance completeness and feasibility.

A Review of Phase 3 Trials of Dupilumab for the Treatment of Atopic Dermatitis in Adults, Adolescents, and Children Aged 6 and Up

Atopic dermatitis (AD) is a chronic pruritic skin disease that can have a profound negative impact on patients' quality of life, especially in cases of inadequate disease control. Dupilumab, a dual inhibitor of IL-4 and IL-13 signaling, is approved in the United States for the treatment of moderate-to-severe AD in adults (≥ 18 years old) and in children (≥ 6 years old). In this review, we present results from phase 3 trials evaluating dupilumab's efficacy and safety in adults, adolescents, and children. These trials demonstrate that dupilumab provides rapid improvements (in as little as 1 week) and sustained efficacy (up to 4 years) when used as a treatment for moderate-to-severe AD. Dupilumab not only improves skin signs and symptoms, but also provides multiple health benefits beyond the skin, including improvements in quality of life, itch, sleep disturbances, and pain/discomfort. Dupilumab is generally well tolerated, has a favorable safety profile in adults, adolescents, and children, has no serious drug-drug interactions, does not require routine laboratory testing, and is not an immunosuppressant. Taken together, phase 3 trials demonstrate that dupilumab provides rapid and sustained efficacy and is generally well tolerated for the treatment of moderate-to-severe AD across age groups.
