A Study of Baricitinib (LY3009104) in Participants With Severe or Very Severe Alopecia Areata

Purpose

This study is designed to select up to two doses of baricitinib (referred to as low dose and high dose) and assess their efficacy and safety for the treatment of severe or very severe alopecia areata. An additional subpopulation of 60 participants in the US will enroll in the open-label addenda.

Condition

  • Alopecia Areata

Exclusion Criteria

  • Primarily "diffuse" type of AA. - Are currently experiencing other forms of alopecia or any other concomitant conditions that would interfere with evaluations of the effect of study medication on AA. - Previously treated with an oral Janus kinase (JAK) inhibitor and had an inadequate response (for example, absence of significant terminal hair growth after at least 12 weeks of treatment).

Placebo Phase 2
Participants received three placebo tablets administered orally once daily (QD). Rescue therapy with Baricitinib 2 mg or 4 mg was provided to participants who failed to achieve Severity of Alopecia Tool (SALT) ≤20 (less than or equal to 20) during the study period.
