June 2026 in “Dermatology and Therapy” In the first 10 months following its FDA approval in June 2023, ritlecitinib was prescribed to a diverse group of patients aged ≥12 years with severe alopecia areata (AA) in the USA. This study analyzed data from 2,562 patients in cohort 1 and 381 in cohort 2, revealing that 62% were prescribed ritlecitinib by dermatologists, 59% were female, and 35% were adolescents. Approximately 24% had severe AA forms like alopecia totalis or universalis, 12% had other autoimmune disorders, 24% had atopic disorders, and 24% had mental health conditions. Before starting ritlecitinib, 27% had no prior AA treatments, while about one-third received systemic immunomodulators or injectable corticosteroids. In cohort 2, 77% experienced ≥50% scalp hair loss. The findings suggest ritlecitinib offers new opportunities for engaging patients in AA care, regardless of their treatment history or comorbidities.
