Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants Achieving an Absolute Severity of Alopecia Tool (SALT) Score =20 at Week 24	SALT is a quantitative assessment of scalp hair loss with scores ranging in severity from 0 (no scalp hair loss) to a maximum of 100 (complete scalp hair loss).	Week 24
Secondary	Percentage of Responders on the Hair Satisfaction Participants Reported Outcome (SPRO) Scale at Weeks 12, 16, 20, and 24	SPRO is a questionnaire answered by the participant and designed to measure how satisfied alopecia areata participants are with their hair at the time of the assessment. The responses range from 1 to 5: 1= very satisfied, 2= satisfied, 3= neither satisfied nor dissatisfied, 4= dissatisfied, and 5= very dissatisfied. Responders were defined as participants with responses of "satisfied" or "very satisfied".	Weeks 12, 16, 20, and 24
Secondary	Percentage of Participants Achieving an Absolute SALT Score of =20 at Weeks 4, 8, 12, 16, and 20	SALT is a quantitative assessment of scalp hair loss with scores ranging in severity from 0 (no scalp hair loss) to a maximum of 100 (complete scalp hair loss).	Weeks 4, 8, 12, 16, and 20
Secondary	Relative Change in SALT Scores From Baseline at Weeks 4, 8, 12, 16, 20, and 24	SALT is a quantitative assessment of scalp hair loss with scores ranging in severity from 0 (no scalp hair loss) to a maximum of 100 (complete scalp hair loss). Relative change (percent change) to baseline is calculated as: 100 x ([post-baseline SALT score - baseline SALT score]/baseline SALT score).	Baseline, Weeks 4, 8, 12, 16, 20, and 24
Secondary	Percentage of Responders Assessed Using the Clinician Global Impression of Improvement (CGI-I) at Weeks 12, 16, 20, and 24	The CGI-I is a questionnaire that asks the clinician to evaluate the improvement or worsening of the participant's alopecia areata as compared to the start of the study on a 7-point scale. Responses range from 1 (very much worse) to 7 (very much improved). Responders were defined as participants with responses of 6 (much improved) or 7 (very much improved).	Weeks 12, 16, 20, and 24
Secondary	Percentage of Responders Assessed Using the Patient Global Impression of Improvement (PGI-I) at Weeks 12, 16, 20, and 24	The PGI-I is a self-administered questionnaire that asks the participant to evaluate the improvement or worsening of their alopecia areata as compared to the start of the study on a 7-point scale. Responses range from 1 (very much worse) to 7 (very much improved). Responders were defined as participants with responses of 6 (much improved) or 7 (very much improved).	Weeks 12, 16, 20, and 24
Secondary	Change in the Clinician Global Impression of Severity (CGI-S) Scores From Baseline at Weeks 12, 16, 20, and 24	The CGI-S is a questionnaire that asks the clinician to evaluate the symptom severity of the participant's alopecia areata at the time of assessment. The symptom severity was rated on a scale ranging from 1 to 7, where 1=normal, no hair loss; 2=borderline hair loss; 3=mild hair loss; 4=moderate hair loss; 5=marked hair loss; 6=severe hair loss; 7=among the most extreme hair loss. Higher scores indicate more hair loss. A negative change from baseline indicates less hair loss.	Baseline, Weeks 12, 16, 20, and 24
Secondary	Change in the Patient Global Impression of Severity (PGI-S) Scores From Baseline at Weeks 12, 16, 20, and 24	The PGI-S is a self-administered questionnaire that asks the participant to evaluate the symptom severity of their alopecia areata at the time of assessment. Symptom severity was rated on a scale ranging from 1 to 7, where 1= normal, no hair loss; 2= borderline hair loss; 3= mild hair loss; 4= moderate hair loss; 5= marked hair loss; 6= severe hair loss; 7= among the most extreme hair loss. Higher scores indicate more hair loss. A negative change from baseline indicates less hair loss.	Baseline, Weeks 12, 16, 20, and 24
Secondary	Percentage of Participants Achieving at Least a 75% and 90% Relative Reduction in SALT Score From Baseline at Weeks 12 and 24	SALT is a quantitative assessment of scalp hair loss with scores ranging in severity from 0 (no scalp hair loss) to a maximum of 100 (complete scalp hair loss). Percentage of participants achieving at least a 75% and 90% relative reduction in SALT score from baseline at Weeks 12 and 24 are reported.	Baseline, Weeks 12, and 24
Secondary	Change in the Brigham Eyebrow Tool for Alopecia (BETA) Scores From Baseline at Weeks 12 and 24	BETA is a clinician-rated scale that assesses the total eyebrow hair present. The BETA score is calculated based on hair density and surface area of each individual eyebrow of the participant, ranging from 0 to 3, where 0= no eyebrow, 1= minimal eyebrow, 2= moderate eyebrow, and 3= normal eyebrow. The BETA score is the sum of the right and left eyebrow scores, ranging from 0 to 6. Higher scores indicate less hair loss of eyebrows. A positive change from baseline indicates less hair loss of eyebrows.	Baseline, Weeks 12, and 24
Secondary	Change in the Brigham Eyelash Tool for Alopecia (BELA) Scores From Baseline at Weeks 12 and 24	BELA is a clinician-rated scale that assesses the total eyelash hair present. The BELA is calculated based on distribution and grade values, ranging from 0 (no eyelashes) to 3 (full eyelashes). The BELA score is the sum of the individual scores for the left and right eyes, ranging from 0 to 6. Higher scores indicate less hair loss of eyelashes. A positive change from baseline indicates less hair loss of eyelashes.	Baseline, Weeks 12, and 24
Secondary	Change in the SPRO Scale From Baseline at Weeks 12, 16, 20, and 24	SPRO is a questionnaire answered by the participant and designed to measure how satisfied alopecia areata participants are with their hair at the time of the assessment. The responses range from 1 to 5: 1= very satisfied, 2= satisfied, 3= neither satisfied nor dissatisfied, 4= dissatisfied, and 5= very dissatisfied.

Secondary	Percentage of Participants Achieving a =2-point Change From Baseline in the SPRO Scale at Weeks 12, 16, 20, and 24	SPRO is a questionnaire answered by the participants and designed to measure how satisfied alopecia areata participants are with their hair at the time of the assessment. The responses range from 1 to 5: 1= very satisfied, 2= satisfied, 3= neither satisfied nor dissatisfied, 4= dissatisfied, and 5= very dissatisfied.	Weeks 12, 16, 20, and 24
Secondary	Change in the Individual Items of the Hair Quality Patient Reported Outcome (QPRO) Scale From Baseline at Weeks 12, 16, 20, and 24	The QPRO questionnaire provides additional details on key attributes of hair and helps provide context to the SPRO response. The individual items of QPRO are: Satisfied thickness hair coverage; Satisfied evenness hair coverage; How satisfied with your eyebrows; How satisfied with your eyelashes, scored on a scale ranging from 1 to 5 where 1=very satisfied, 2=satisfied, 3=neither satisfied nor dissatisfied, 4=dissatisfied, 5=very dissatisfied. Higher scores indicate the greater dissatisfaction on hair quality. A negative change from baseline indicate the greater satisfaction on hair quality.	Baseline, Weeks 12, 16, 20, and 24
Secondary	Change in the Anxiety and Depression Scale Scores of the Hospital Anxiety and Depression Scale (HADS) From Baseline at Week 24	HADS is questionnaire designed to assess anxiety and depression symptoms which is completed by participants.

Each item within both scales is scored using a 4-point scale, ranging from 0 to 3 and the total scores in each scale can range from 0 to 21. Separate scores were created for anxiety and depression. A score between 0-7 is considered normal, 8-10 is mild, 11-14 is moderate, and >14 is severe anxiety or depression. Higher scores indicate greater severity. A negative change from baseline indicates less severity.	Baseline and Week 24
Secondary	Percentage of Participants Achieving an Absolute SALT Score of =10 at Week 24	SALT is a quantitative assessment of scalp hair loss with scores ranging from 0 (no scalp hair loss) to 100 (complete scalp hair loss).	Week 24
