TLDR Continuous baricitinib is needed to keep hair regrowth in severe alopecia areata.
The BRAVE-AA1 trial investigated the effects of baricitinib withdrawal and retreatment in 654 adults with severe alopecia areata. After 1 year of treatment, patients who responded were either continued on baricitinib or switched to a placebo. By week 152, 80% of those switched to placebo lost their hair regrowth benefits, compared to only 7% who continued baricitinib. Upon retreatment, 63% of patients on 2 mg and 87.5% on 4 mg regained their hair regrowth. The study concludes that continuous baricitinib therapy is necessary to maintain hair regrowth in severe alopecia areata.
