Real-world evidence of dupilumab efficacy and risk of adverse events: A systematic review and meta-analysis.

BACKGROUND

Dupilumab, the first biological drug to be approved for the treatment of moderate to severe atopic dermatitis in adolescents and adults, has shown good efficacy and safety in clinical trials.

OBJECTIVE

To evaluate real-world data on the efficacy and safety of dupilumab in atopic dermatitis.

METHODS

PubMed and EMBASE were searched for observational studies with data on efficacy, drug survival, and safety of dupilumab for the treatment of atopic dermatitis. Primary outcomes were mean percentage change in Eczema Area and Severity Index (EASI) score and proportion of atopic dermatitis patients achieving 50%, 75%, and 90% improvement in EASI score after dupilumab therapy.

RESULTS

Twenty-two unique studies encompassing 3303 atopic dermatitis patients were included. After 16 weeks of dupilumab therapy, the pooled proportion of patients achieving 50%, 75%, and 90% EASI score improvement was 85.1%, 59.8%, and 26.8%, respectively, and the weighted mean reduction in EASI score was 69.6%. Conjunctivitis was the most common adverse event, reported in a pooled proportion of 26.1%.

LIMITATIONS: Limited data in terms of size and follow-up time were available.

CONCLUSION

Real-world data show that dupilumab is a successful and well-tolerated therapy for atopic dermatitis, but ocular adverse events commonly occur. Registries are needed to monitor for adverse events.
