Characteristics of Atopic Dermatitis Patients Treated with Crisaborole: Real-World Data from a Large Healthcare Provider Database in Israel

Abstract

Background

In recent years, new treatments dedicated to atopic dermatitis (AD) have become available in Israel, including crisaborole, a small molecule with unique benzoxaborole chemistry.

Objective

To describe baseline characteristics, history of AD therapies, and use of health-care services of early crisaborole users in real-world settings.

Methods

A retrospective cohort study was performed using the data of a large health provider in Israel. AD patients treated with crisaborole since it became commercially available in Israel in July 2019 through end of Sep 2020, were included. Baseline demographics and clinical characteristics, prior AD-related treatments and healthcare resource utilization were collected.

Results

A total of 441 patients were included (57.8% females, median age = 21.1y; interquartile range = 10.5–40.8). In 62.1%, a dermatologist prescribed the first dispensed crisaborole. Median time from AD diagnosis to crisaborole treatment was 6.6 years. Up to 12 months prior to crisaborole treatment, low-, mid- and high-potency TCS were used by 30.8%, 31.1% and 55.8% of patients, respectively. Treatments related to moderate-to-severe AD were dispensed to 38.5% of patients in the prior 5 years. Asthma and allergic rhinitis were documented among 22.2% and 37.2%, respectively. In the past year, patients had a median of 9 visits to primary care physicians, 84.6% visited a dermatologist (≥5 visits: 12.9%).

Conclusion

While crisaborole is indicated for mild-to-moderate disease, results suggest that a significant proportion of patients had history of advanced AD therapies suggestive of moderate-to-severe AD.
