Abstract
Background
Systemic therapy for atopic dermatitis (AD) has been challenging with limited safe and efficacious long-term treatment options. In 2017, dupilumab was approved in the United States, Europe, and Canada as the first targeted therapy for patients with moderate-to-severe AD. Despite promising efficacy and safety results in clinical trials, our understanding of dupilumab in clinical practice remains limited with few studies outside clinical trials in literature.
Objective
The aim of this study is to evaluate the efficacy and safety of dupilumab in clinical practice and discuss any differences in results between clinical trials and real-world results.
Methods
A retrospective chart review was conducted of consecutive patients receiving dupilumab treatment at two tertiary hospitals in Toronto, Canada, between December 2017 and May 2019. The primary efficacy endpoint was measured by Investigator’s Global Assessment (IGA) score of 0/1 at 16 weeks and all adverse events (AEs) experienced by patients were recorded.
Results
Of the 93 patients included in the study, 51 (55%) reached IGA 0/1 and 38 (41%) experienced ≥1 AE. There were no severe AEs or discontinuation prior to 16 weeks due to an AE.
Conclusions
These findings suggest a higher IGA-based efficacy profile with no newly identified safety concerns in patients treated with dupilumab at two tertiary hospitals in Toronto, Canada, compared to those in randomized controlled trials.
