What Did the Trials Show for Eyebrow and Eyelash Regrowth?
Gooderham said eyebrow and eyelash outcomes were clinically meaningful secondary end points, noting that roughly two-thirds of patients had significant eyebrow loss and half had significant eyelash loss at baseline. She explained that this type of hair loss is particularly difficult for patients to conceal compared with scalp hair loss, and also carries functional consequences, since eyebrows and eyelashes help protect the eyes from sweat and debris. At Week 24, approximately 40% of patients on the 15-mg dose and 60% of patients on the 30-mg dose achieved meaningful eyebrow and eyelash regrowth.
How Do the Safety Findings Affect Confidence in Upadacitinib for This Population?
Gooderham said no new safety signals were identified in the trials, reinforcing her confidence in upadacitinib given the extensive existing safety data from other approved indications, including atopic dermatitis, rheumatoid arthritis, and inflammatory bowel disease. She noted that in a cross-trial comparison, other therapies for severe alopecia areata have shown SALT score 20 or less response rates around 35%, compared with 45% and 55% for the 15-mg and 30-mg upadacitinib doses, respectively, though she cautioned this was not a head-to-head comparison.
Gooderham said the data may raise the standard of care for patients with severe alopecia areata, many of whom have previously abandoned treatment. She emphasized that upadacitinib's benefits extend beyond the scalp to eyebrows, eyelashes, and beard growth in men, and pointed to a favorable risk-benefit profile in adolescents specifically, a population in which alopecia areata can carry significant psychosocial impact.
