Proportion of subjects achieving Eczema Area and Severity Index(EASI-75) at week 18
The EASI is a composite index with scores ranging from 0 to 72. Four Atopic Dermatitis(AD) disease characteristics (erythema, edema/papulation, excoriation, lichenification) will each be assessed for severity by the investigator on a scale of "0" (none) through "3" (severe).
