Outcomes

Primary Outcomes

Responder Rate of Investigator's Global Assesment(IGA) of Disease Severity

The investigator or subinvestigator assessed the skin symptoms using IGA. The investigator or subinvestigator scored the severity (0 = clear, 1 = almost clear, 2 =mild, 3 = moderate, 4 = severe/very severe) of the overall symptoms of the treatment area (erythema, infiltration, papules, effusion and scab formation) from baseline to Week 4. Incidence of success in IGA is defined as the rate of subjects whose IGA score is 0 (clear) or 1 (almost clear) and has improved by at least 2 grades (responders) from baseline.

Time frame: At Week 4

Secondary Outcomes

Change From Baseline in Eczema Area and Severity Index (EASI) Score

The investigator or sub investigator assessed the symptoms of AD using EASI. EASI's minimum and maximum scores are 0 and 72 scores respectively. The higher the EASI score is, the more severe the symptoms of AD, and a negative change from the baseline means improvement and a positive change means worsening. The investigator or sub investigator scored the severity (0-3 points) and affected BSA (%) based on the 4 symptoms (erythema, infiltration/papules, excoriation, and lichenification) on the 4 body regions (face, neck and head ; upper limbs ;trunk; and lower limbs).

Time frame: Baseline, Week 4

Change From Baseline in Verbal Rating Scale (VRS) for Pruritus Score

The investigator or subinvestigator evaluated the pruritus intensity based on VRS. The subjects evaluated the pruritus intensity according to the following criteria. The subjects recorded the level of pruritus and the time and date of evaluation in a pruritus diary. 0: None 1. Mild 2. Moderate 3. Severe

Time frame: Baseline, Week 4
