Retrospective analysis of adverse events with dupilumab reported to the United States Food and Drug Administration.

BACKGROUND:Atopic dermatitis (AD) is one of the most common inflammatory skin diseases and has aesthetic, physical, and emotional-social sequelae when left untreated. OBJECTIVE:To classify the most common adverse reactions associated with dupilumab treatment in patients with AD. METHODS:The United States Food and Drug Administration Adverse Event Reporting (FAERS) database was analyzed for common adverse reactions associated with dupilumab, topical pimecrolimus, and topical tacrolimus. Phase III clinical trial data were used to compare the rate of herpes infections between the treatment group and placebo group. RESULTS:The most common adverse reaction associated with dupilumab was ocular complications. Herpes infections were extremely rare in the patients with AD being treated with dupilumab. LIMITATIONS:Prescribing information for dupilumab, topical pimecrolimus, and topical tacrolimus is not available. Adverse effects are reported by patients, health care providers, and pharmaceutical companies, they have not been corroborated. CONCLUSIONS:Ocular complications are the most common complication associated with dupilumab. The rate of herpes infection is low in patients being treated with dupilumab, topical pimecrolimus, and topical tacrolimus. There is no significant difference for the rate of herpes infection between, placebo, dupilumab, topical pimecrolimus, and the topical tacrolimus treatment group, suggesting that dupilumab does not affect herpes infection rates.
