What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Reduction of Worst Itch in Atopic Dermatitis
Time Frame: 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].
8 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Improvement of Disease Severity in Atopic Dermatitis
Time Frame: 8 weeks
Proportion of participants achieving 50% reduction on the SCORing Atopic Dermatitis (SCORAD) index. SCORAD is an assessment scale used to determine the severity of AD. SCORAD combines the investigator's rating of extent and intensity and the patient reported itch and sleep disturbance. Total score ranges from 0 (absent disease) to 103 (severe disease).
8 weeks
Proportion of Patients With Improvement on Investigator Global Assessment for Atopic Dermatitis (vIGA-AD) of at Least 2-point Reduction
Time Frame: 8 weeks
As measured by the validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD). IGA is an assessment scale used to determine severity of AD. It is assessed by the investigator on a 5-point scale (0=clear, 1=almost clear, 2=mild, 3=moderate, 4=severe) based on erythema, induration/papulation, lichenification, and oozing/crusting.
