Tofacitinib (Selective Janus Kinase Inhibitor 1 and 3): A Promising Therapy for the Treatment of Alopecia Areata: A Case Report of Six Patients.

BACKGROUND: Alopecia areata (AA) is a chronic autoimmune disorder characterized by patchy loss of hair from scalp, beard, eyebrows, or rarely even body hair. Rarely, the disease can be widespread and severe leading to loss of entire scalp and body hair causing apprehension and psychological stress in patients. Management of such cases is equally difficult with the available options of topical and systemic immunosuppressant. Tofacitinib, JAK3 inhibitor, is emerging as a promising drug for the management of severe and resistant cases of AA/totalis/universalis.

OBJECTIVE: Our study aims to show the effectiveness of oral tofacitinib in the treatment of alopecia universalis (AU).

METHODS: Six patients diagnosed with AU/alopecia totalis duration of disease 6 months-15 years refractory to other treatments were selected and were started on oral tofacitinib 5 mg twice daily up to 10 mg BID and were followed up every 4 weeks. The efficacy was measured by hair regrowth using photographic assessment, Severity of Alopecia Tool score, and physical examination. Patients will be followed up for 6 months after stopping treatment for assessing disease relapse.

RESULTS: All our six patients showed dramatic response to oral tofacitinib. Patients were followed up every 4 weeks, and results were assessed. Significant hair regrowth was evident in all the patients by the end of 12 weeks. Currently, four of our patients are on oral tofacitinib 10 mg BID and are under follow-up. There was no relapse in one patient after stopping drug for 4 months. Another patient started developed AA patches in the eyebrows within 2 months of stopping tofacitinib. Acneiform eruptions were seen in two patients which were managed with topicals.

CONCLUSION: In our patients, tofacitinib successfully alleviated AU in the absence of significant adverse side effects. We recommend that further controlled studies be required to establish safety and confirm efficacy.
