About Alopecia Areata
Alopecia areata, or AA, is a T-cell-mediated autoimmune skin disorder with unmet medical need that causes non-scarring patchy hair loss, most often on the scalp. Mild disease typically presents as one or more round or oval bald patches on the scalp. In moderate-to-severe disease, extensive and chronic hair loss occurs, with the most severe forms involving hair loss on the entire scalp (alopecia totalis) or body (alopecia universalis). Patients with persistent moderate-to-severe AA also often suffer emotional and psychosocial distress and reduced quality of life as a result of their hair loss.
Etrasimod (APD334) is a next generation, once-daily, oral, highly selective sphingosine 1-phosphate (S1P) receptor modulator discovered by Arena, and designed for optimized pharmacology and engagement of S1P receptor 1, 4 and 5 which may lead to an improved efficacy and safety profile.
Etrasimod provides systemic and local effects on specific immune cell types and has the potential to treat multiple immune-mediated inflammatory diseases, including ulcerative colitis, Crohn's disease, atopic dermatitis and alopecia areata.
Etrasimod is an investigational compound that is not approved for any use in any country.
In a rapidly changing global market, we work with a sense of urgency every day to understand the needs of all our stakeholders, identify bold, sometimes disruptive, ideas to get our medicines to patients, and relentlessly execute until it's done.
