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.

Baseline and Month 12

The Investigator Global Assessment is a single-item observer-rated scale of scalp hair loss scored from 0 to 4, where 0 is none and 4 is very severe. One score is recorded per participant per timepoint. Change from baseline is the Month 12 score minus the baseline score, reported in units on a scale. A negative value indicates improvement.

Change in Oral Disease Severity Scale (ODSS) Scores
Baseline, 24 weeks

The Oral Disease Severity Scale (ODSS) is a validated tool to assess severity of Oral Lichen Planus. For scoring, the oral cavity is divided into 17 sites and assigned three different scores. A site score, which captures disease extent, a severity score, and an activity score which is obtained by multiplying the site and severity scores. Independently study participants are asked to fill in a numerical rating scale graded from 0-10, with zero meaning no pain and 10 being the worst imaginable pain felt within the last 4 weeks. Scores are added together and range from 0-106, with higher scores meaning more severe disease. Overall change from baseline to week 24 will be reported.

52 weeks

The primary objective is to determine if the administration of baricitinib to participants with Aicardi-Goutières Syndrome (AGS) results in a change or stability of the AGS scale from baseline to 52 weeks. The AGS scale is a neurologic scale used to evaluate neurologic function of participants under treatment. The scale includes items for head circumference and developmental milestones. A lower score suggests a worse outcome. The range of scores is from 0 (most severe) to 11 (least severe).

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

Antiretroviral Therapy (ART)DRUGAntiretroviral Therapy (ART): A treatment regimen for HIV infection that uses a combination of antiretroviral drugs to suppress viral replication, reduce HIV-related morbidity, and prevent transmission. In Step 1, participants will continue their current ART regimen for 25 weeks. In Step 2, participants will interrupt ART. In Step 3, participants will restart ART early if they meet the ART restart criteria before the end of Step 2 (a 25-week maximum). Otherwise, they will resume ART at the end of Step 2.
