Primary Outcome Measures
NameTimeMethod
Percent Change From Baseline in Severity of Alopecia Tool I (SALT I) at Week 24: DB Treatment PeriodDB Treatment Period: Baseline (before dose on Day 1), Week 24

SALT I is a well-validated metric used to determine the degree of hair loss based on the percentage (%) of scalp surface area involved on the top (40%), back (24%), left side (18%) and right side (18%) of the scalp for AA. Investigator determines the % scalp hair loss in a given quadrant, multiply this by the total scalp area delineated by that quadrant, and sum the resultant numbers for each quadrant to give the total % scalp hair loss with a maximum score of 100. Score range from 0% (no scalp hair loss) to 100% (complete scalp hair loss), higher scores indicated more scalp hair loss. Percent change from baseline in SALT I is reported in terms of Least square mean and standard error.

Percentage of Participants Who Achieved Greater Than or Equal to (>=) 30%, >= 50% and >=75% Improvement From Baseline in SALT I at Week 24: DB Treatment PeriodDB Treatment Period: Baseline, Week 24

SALT I is a well-validated metric used to determine the degree of hair loss based on the percentage of scalp surface area involved on the top, back, and each side of the scalp for alopecia areata (AA). Investigator determine the percent scalp hair loss in a given quadrant, multiply this by the total scalp area delineated by that quadrant, and sum the resultant numbers for each quadrant to give the total percent scalp hair loss with a maximum score of 100. Score range from 0 to 100, where 0 =no scalp hair loss to 100 = complete scalp hair loss, higher scores indicated more scalp hair loss. Percentage of participants who achieved \>=30%, \>=50%, \>=75% improvement from baseline in SALT I at Week 24 was reported in this outcome measure.
