Topical Tofacitinib for the Treatment of Alopecia Areata and Its Variants

This will be an open label clinical trial. We plan to treat 10 adults with AA (with at least
2 patches of alopecia involving the scalp), AT or AU with tofacitinib ointment for a maximum
of 6 months. During treatment, patients will be evaluated every 4 weeks and effectiveness of
the medication will be measured by changes in hair growth. Laboratory evaluation will be
performed before and during treatment in order to monitor for adverse effects of the
medication.
