RESULTS Patient Subgroups Note: Figure is not the full study design, but only the PBO-Controlled Period of both trials Key Eligibility Criteria for BRAVE-AA1 and BRAVE-AA2 Inclusion ■ Age ≥18 years to ≤60 years (males) or ≤70 years (females) ■ Severe or very severe AA – Hair loss encompassing ≥50% of the scalp, as measured by the Severity of Alopecia Tool (SALT) ■ Current episode of AA lasting >6 months to <8 yearsa Exclusion ■ No spontaneous improvement in the 6 months before screening ■ Not primarily a “diffuse” type of AA ■ No concomitant treatments for AA allowedb a Patients who had AA for ≥8 years could be enrolled if episodes of regrowth (spontaneous or due to under-treatment) had been observed on the affected areas over the past 8 years b Oral/topical minoxidil or finasteride were allowed if on stable dose for 12 months and bimatoprost ophthalmic solution was allowed if on stable dose for 8 weeks SALT Score3 ■ Assesses hair loss in each quadrant of the scalp ■ The SALT score is a weighted sum of the percent of hair loss in the 4 quadrants of the scalp, ranging from 0 to 100 ■ Examples: – SALT 0=no scalp hair loss​ – SALT 50=50% scalp hair loss​ – SALT 100=complete scalp hair loss ■ Patients were categorized into 3 groups according to scalp hair regrowth at Week 36: 1. SALT ≤20 Response (N=256): Met the primary endpoint of SALT ≤20 (ie, ≥80% scalp hair coverage) 2. Intermediate Response (N=268): Did not meet the primary endpoint but achieved ≥30% improvement from baseline in SALT score at any post- baseline visit up to Week 36 (SALT30) 3. No or Minimal Response (N=676): Did not achieve SALT30 at any post-baseline visit up to Week 36 Assessments Skindex-16 adapted for AA: Assessed effects of AA on HRQoL over 3 domains: ■ Emotions, symptoms, and functioning ■ Each domain score ranged from 0 to 100, with higher scores indicating worse HRQoL Hospital Anxiety and Depression Scale (HADS): Assessed levels of anxiety (HADS-A) and depression (HADS-D)a ■ Each domain score ranged from 0 to 21, with higher scores indicating greater anxiety or depression ■ Used to identify patients with borderline or abnormal severity scores at baseline (HADS-A ≥8 or HADS-D ≥8) a Patients with significant uncontrolled neuropsychiatric disorder were not eligible for the study Statistical Analyses ■ Data were pooled from the 3 arms (placebo, baricitinib 4-mg, and baricitinib 2-mg) of BRAVE-AA1 and BRAVE-AA2 and analyzed independently of treatment allocation ■ Change from baseline in Skindex-16 domains, HADS-A, and HADS-D scores were analyzed using analysis of covariance with modified last observation carried forward imputation for missing data – Data after permanent study drug discontinuation were censored and not carried forward ■ Percentage of patients who shifted from borderline or abnormal to normal HADS-A and HADS-D scores were analyzed using logistic regression with non- responder imputation Demographics and Baseline Characteristics, by Hair Regrowth Response Group Response Categories According to Scalp Hair Regrowth at Week 36 for Pooled Treatment Arms SALT ≤20 Response (N=256) Intermediate Response (N=268) No or Minimal Response (N=676) Age, years 37.4 (12.5) 37.3 (12.6) 37.7 (13.1) Female, n (%) 166 (64.8) 149 (55.6) 413 (61.1) Duration from onset of AA, years 9.0 (9.3) 11.5 (10.7) 13.6 (11.2) Duration of current AA episode, years 3.0 (3.5) 3.5 (3.0) 4.4 (5.0) SALT score 77.3 (18.9) 81.8 (18.3) 89.8 (16.1) SALT category, n (%) Severe (SALT 50-94) 179 (69.9) 157 (58.6) 225 (33.3) Very severe (SALT 95-100) 77 (30.1) 111 (41.4) 450 (66.7) Skindex-16 AA domain scorea Symptoms 19.4 (20.2) 19.0 (20.9) 17.6 (19.9) Emotions 70.3 (25.9) 68.3 (27.3) 67.0 (28.7) Functioning 52.4 (30.9) 50.0 (32.6) 49.5 (32.2) Patients with B/AB anxiety (HADS-A ≥8), n (%) 94 (36.7) 96 (35.8) 220 (32.5) Patients with B/AB depression (HADS-D ≥8), n (%) 44 (17.2) 52 (19.4) 104 (15.4) HADS-A scoreb 10.5 (2.7) 10.3 (2.3) 10.7 (2.8) HADS-D scoreb 10.0 (1.9) 9.7 (2.0) 9.9 (2.0) * p<0.05; ** p<0.01; *** p<0.001 vs. no or minimal response Patients With a SALT ≤20 Response at Week 36 Were More Likely to Achieve Normal Anxiety and Depression Scores (HADS <8) * p<0.05; ** p<0.01 vs. no or minimal response in patients with borderline or abnormal severity scores at baseline (HADS-A ≥8 or HADS-D ≥8) Greater Improvement (Decrease) in All Skindex-16 AA Domain Scores Was Observed in Patients With a SALT ≤20 Response at Week 36 Greater Improvement (Decrease) in Anxiety and Depression Scores Was Observed in Patients With a SALT ≤20 Response at Week 36 * p<0.05; vs. no or minimal response in patients with borderline or abnormal severity scores at baseline (HADS-A ≥8 or HADS-D ≥8) Data are mean (standard deviation) unless stated otherwise a In patients with baseline assessment of Skindex-16 adapted for AA b In patients with baseline HADS-A ≥8 or HADS-D ≥8
