Safety and Efficacy of the JAK Inhibitor Tofacitinib Citrate for Alopecia Areata and Variants

The samples include RNA from scalp biopsies before treatment and at 8 weeks of treatment with Tofacitinib Citrate 5 mg BID in patients with Alopecia Areata. 32% had a SALT score of 50% or higher and 47% had clinically significant response. Overall design: Open label trial of patients with Alopecia Areata of more than 6 months in duration refractory to standard therapy. Each patient took tofacitinib citrate 5mg BID for 3 months and then stopped. Biopsies were taken pretreatment and then at 8 weeks from the scalp and submitted for RNA sequencing.
