Treatment Patterns and Treatment Satisfaction Among Adults with Alopecia Areata in the United States

Abstract

Introduction: Alopecia areata (AA), an autoimmune disease, is characterized by non-scarring hair loss involving the scalp, face, and/or body. Prior to 2022, no US Food and Drug Administration (FDA)-approved treatments for AA were available in the USA; existing treatment options had limited efficacy and durability and are often associated with side effects. This study aimed to evaluate the current AA treatment patterns and treatment satisfaction as reported by dermatologists. Methods: Real-world data from a 2019 cross-sectional survey of US dermatologists and their adult patients with AA were analyzed. Dermatologists provided comprehensive data on their patients with AA, including AA dermatologist-assessed severity, treatments, treatment duration, treatment satisfaction, and reasons for dissatisfaction. The switching patterns among the proportion of patients on each of the treatment groups at the time of survey and, for those with prescription history, were reported. Results: A total of 442 patients with AA, treated by 90 dermatologists, were included in this analysis. At the time of survey, 45% of patients were being prescribed a combination of corticosteroids, 21% injectable corticosteroids, 11% topical corticosteroids/topical calcineurin inhibitor, and 10% immunomodulator as monotherapy or in combination. The majority (65%) of patients had no prior reported therapy. Among patients who were reported to have a prior therapy, frequent switching was to combination corticosteroids, injectable corticosteroids, and immunomodulators. Overall treatment dissatisfaction was high (24% dissatisfied and 29% neutral) and increased with AA severity. Conclusions: This analysis provides a snapshot of the different local and systemic treatment options currently being used in a real-world treatment setting. Unfortunately, none of these treatments provide a sustainable, safe, and relapse-free solution, which leads to high treatment dissatisfaction rates and hence indicates a significant unmet need for the new and advanced treatment options for patients with AA.
