结局指标
主要结局
Responder Rate of Investigator's Global Assesment(IGA) of Disease Severity
时间窗: At Week 4
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.
次要结局
- Change From Baseline in Verbal Rating Scale (VRS) for Pruritus Score(Baseline, Week 4)
- Change From Baseline in Eczema Area and Severity Index (EASI) Score(Baseline, Week 4)
