Primary outcomes

  1. Percentage of Participants Achieving Severity of Alopecia Tool (SALT) ≤ 20 - Phase 3

    Time frame: Week 36

    The SALT uses a visual aid showing the division of the scalp hair into 4 areas with the top of the head constituting 40% of total surface, the posterior/back of head 24%, right side and left side of head 18% each. The percentage of hair loss in each area is determined and is multiplied by the percentage of scalp covered by that area. The total sum of the 4 products of each area will give the SALT score, as developed by the National Alopecia Areata Foundation Working Committee. Only terminal hair is included in the SALT; vellus hair or any fine downy hair is not taken into account in the SALT scoring process. The SALT score will range from 0% to 100%, with lower score indicating better health outcomes.

  2. Percent Change From Baseline in SALT Score - Phase 3 Open-Label Addendum

    Time frame: Baseline, Week 52

    The SALT uses a visual aid showing the division of the scalp hair into 4 areas with the top of the head constituting 40% of total surface, the posterior/back of head 24%, right side and left side of head 18% each.

    Time frame: Baseline, Week 36

    The Hospital Anxiety Depression Scale (HADS) is a 14 item self-assessment scale that determines the levels of anxiety and depression that a patient is experiencing over the past week. The HADS utilizes a 4-point Likert scale (e.g., 0 to 3) for each question and is intended for ages 12 to 65 years. Scores for each domain (anxiety and depression) can range from 0 to 21, with higher scores indicating greater anxiety or depression.

    LS mean was calculated using an ANCOVA model which includes geographic region, duration of current episode at baseline (<4 years vs. ≥4 years), treatment group and baseline score as fixed factors.
