Study Endpoints
Primary Endpoints
Reduction of Worst Itch in Atopic Dermatitis
8 weeks

Reduction of worst itch in atopic dermatitis as measured by Numerical Rating Scale (NRS). Worst Itch NRS is an assessment tool that is used to report the maximum intensity of participant's itch during a 24-hour recall period. Participants were asked the following question: Please rate the itching severity that describes your worst level of itching in the past 24 hours \[0=No Itch, 10=Worst Itch Imaginable\].

Mean Change From Baseline in Pruritus Symptoms, as Measured by the 24-hour Average Pruritus Visual Analogue Scale (VAS) Score
56 days

Responses were measured on a 100-mm Visual Analogue Scale (VAS), where the left endpoint was marked "no itch" (0 mm) and in the right endpoint was marked "worst imaginable itch" (100 mm).
