Evaluating crisaborole as a treatment option for atopic dermatitis

Introduction: Atopic dermatitis (AD) is a chronic and recurrent disease presenting with eczematous lesions and pruritus. It impacts patient and family quality of life, increases morbidity, and accounts for large health-care expenditures. Although nonpharmacologic, topical, and systemic treatments exist, management of AD remains challenging due to limited treatment options. Crisaborole is a topical small molecule inhibitor of phosphodiesterase 4 (PDE4), recently approved for the treatment of AD in the United States.

Areas covered: The authors review crisaborole in the management of AD based on Phase II, Phase III, and post-marketing studies. Pharmacologic properties such as chemistry, pharmacokinetics, pharmacodynamics and metabolism are discussed. A PubMed systematic review was augmented with Google Scholar searches via keyword, Medical Subject Headings (MeSH), and Boolean operation searches.

Expert opinion: Crisaborole showed modest efficacy in short-term trials, but head-to-head trials with topical corticosteroids and tacrolimus are needed to assess its clinical utility. Since crisaborole is non-steroidal, it may reduce the need for topical corticosteroids and address steroid phobia. However, it is likely to suffer from the same factors contributing to intentional non-adherence in topicals: dissatisfaction with efficacy and inconvenience.
