Eligibility
Inclusion criteria
* Are at least 18 years and ≤60 years for males (≤70 years of age for females) at the time of informed consent. * Have severe or very severe AA, as determined by all of the following: * Current AA episode of more than 6 months' duration and hair loss encompassing ≥50% of the scalp, as measured by SALT (AA-IGA of 3 or 4) at screening and baseline. * No spontaneous improvement over the past 6 months. * Current episode of severe or very severe AA of less than 8 years. Note: participants who have severe or very severe AA for ≥8 years may be enrolled if episodes of regrowth, spontaneous or under treatment, have been observed on the affected areas over the past 8 years. * Male or nonpregnant, nonbreastfeeding female participants.
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).
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants Achieving Severity of Alopecia Tool (SALT) ≤ 20 | 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. |

| Change From Baseline in Skindex-16 Alopecia Areata (AA) Symptoms Domain Score | Baseline, Week 36 | Skindex-16 AA was adapted from Skindex-16 for use among adults with alopecia areata. It examines the degree to which the participant is bothered by alopecia (hair loss) and associated symptoms. It is composed of 16 items grouped under 3 domains: Symptoms (4 items), Emotions (7 items), and Functioning (5 items). The score of each item ranges from 0 (never bothered) to 6 (always bothered). Symptoms domain score is sum of 4 items, range 0 to 24; Emotions domain score is sum of 7 items, range 0 to 42; Functioning score is sum of 5 items, range 0 to 30. Higher scores indicate a greater impact on quality of life. LS means was calculated using the ANCOVA model with geographic region, duration of current episode at Baseline (\<4 years vs. ≥ 4years), treatment group, and baseline value as fixed factors. |

Outcome results
Percentage of Participants Achieving Severity of Alopecia Tool (SALT) ≤ 20
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.

It is comprised of 4 category response options: 0 = I have full EL on each eyelid; 1 = I have a minimal gap or minimal gaps along the eyelids; 2 = I have a large gap or large gaps along the eyelids; and 3 = I have no or barely any EL hair.
Time frame: Week 36
Population: All randomized participants with baseline PRO Measure EL hair loss ≥2.
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Placebo | Percentage of Participants Achieving PRO Measure for EL 0 or 1 With ≥2-point Improvement From Baseline (Among Participants With PRO Measure EL ≥2 at Baseline) | 1.1 percentage of participants |
| 2 mg Baricitinib | Percentage of Participants Achieving PRO Measure for EL 0 or 1 With ≥2-point Improvement From Baseline (Among Participants With PRO Measure EL ≥2 at Baseline) | 18.9 percentage of participants |
| 4 mg Baricitinib | Percentage of Participants Achieving PRO Measure for EL 0 or 1 With ≥2-point Improvement From Baseline (Among Participants With PRO Measure EL ≥2 at Baseline) | 34.6 percentage of participants |
Percentage of Participants With Patient-Reported Outcome (PRO) for Scalp Hair Assessment Score of 0 or 1 With a ≥2-point Improvement From Baseline Among Participants With a Score of ≥3 at Baseline
PRO is an assessment of the particpant's current extent of scalp involvement. It is comprised of 5 category response options: 0= No missing hair (0% of my scalp is missing hair; I have a full head of hair); 1 = A limited area (1% to 20% of my scalp is missing hair); 2 = A moderate area (21% to 49% of my scalp is missing hair); 3 = A large area (50% to 94% of my scalp is missing hair); and 4 = Nearly all or all (95% to 100% of my scalp is missing hair).
Time frame: Week 36
Population: All randomized participants with baseline PRO for scalp hair assessment score of ≥ 3.
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Placebo | Percentage of Participants With Patient-Reported Outcome (PRO) for Scalp Hair Assessment Score of 0 or 1 With a ≥2-point Improvement From Baseline Among Participants With a Score of ≥3 at Baseline | 4.0 percentage of participants |
| 2 mg Baricitinib | Percentage of Participants With Patient-Reported Outcome (PRO) for Scalp Hair Assessment Score of 0 or 1 With a ≥2-point Improvement From Baseline Among Participants With a Score of ≥3 at Baseline | 16.1 percentage of participants |
| 4 mg Baricitinib | Percentage of Participants With Patient-Reported Outcome (PRO) for Scalp Hair Assessment Score of 0 or 1 With a ≥2-point Improvement From Baseline Among Participants With a Score of ≥3 at Baseline | 34.4 percentage of participants |
Percent Change From Baseline in SALT Score at Week 36
SALT uses a visual aid showing the division of the scalp hair into4 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. 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. Least Squares Mean (LSM) was calculated using analysis of covariance (ANCOVA) with geographic region duration of current episode at baseline (\< 4 years versus ≥4 years), treatment group, and baseline value in the model.
Time frame: Baseline, Week 36
Population: All randomized participants with nonmissing baseline and at least one postbaseline measure. The method used to handle missing data was modified last observation carried forward (mLOCF) which used the most recent nonmissing postbaseline assessment.
| Arm | Measure | Value (LEAST_SQUARES_MEAN) | Dispersion |
|---|---|---|---|
| Placebo | Percent Change From Baseline in SALT Score at Week 36 | -2.96 percentage of change | Standard Error 2.723 |
| 2 mg Baricitinib | Percent Change From Baseline in SALT Score at Week 36 | -28.21 percentage of change | Standard Error 2.77 |
| 4 mg Baricitinib | Percent Change From Baseline in SALT Score at Week 36 | -47.45 percentage of change | Standard Error 2.229 |
