---|---|---|
Number of Participants Who Achieved Treatment Success Based on Investigator's Static Global Assessment (ISGA)
Time Frame: Baseline up to Day 29
|
ISGA assess severity of atopic dermatitis on a 5 point scale ranged from 0 (clear) to 4 (maximum severe), where higher scores indicate higher degree of atopic dermatitis.
Grades for classification of severity: 0= clear (minor residual discoloration, no erythema or induration or papulation, no oozing or crusting), 1= almost clear (trace faint pink erythema, with barely perceptible induration or papulation and no oozing or crusting), 2= mild (faint pink erythema with mild induration or papulation and no oozing or crusting), 3= moderate (pink-red erythema with moderate induration or papulation with or without oozing or crusting) and 4= severe (deep or bright red erythema with severe induration or papulation and with oozing or crusting).
Treatment success was defined as ISGA score of 0 or 1, and a minimum improvement of 2 grades in ISGA from Baseline to Day 29.

Change From Baseline in Signs and Symptoms of Atopic Dermatitis at Day 8, 15, 22 and 29
Time Frame: Baseline, Day 8, 15, 22, 29
|
5 signs and symptoms of atopic dermatitis were: 1) erythema, 2) pruritus, 3) exudation, 4) excoriation and 5) lichenification.
The severity of each of these 5 signs and symptoms were assessed on a 4 point scale, ranging from 0 (none) to 3 (severe).
Higher scores (for each of the 5 signs and symptoms) indicate higher degree of severity of atopic dermatitis.
