Primary Outcome Measures:
  • Percentage of Participants With Investigator's Global Assessment (IGA) Score of "0" or "1" and Reduction From Baseline of ≥2 Points at Week 16 [ Time Frame: Baseline to Week 16 ]
    IGA is an assessment scale used to determine severity of AD and clinical response to treatment on a 5-point scale (0 = clear; 1 = almost clear; 2 = mild; 3 = moderate; 4 = severe) based on erythema and papulation/infiltration. Therapeutic response is an IGA score of 0 (clear) or 1 (almost clear). Participants with IGA score "0" or "1" and a reduction from baseline of ≥2 points at Week 16 were reported.


Secondary Outcome Measures:
  • Percentage of Participants With Eczema Area and Severity Index-75 (EASI-75) (≥75% Improvement From Baseline) at Week 16 [ Time Frame: Baseline to Week 16 ]
    The EASI score was used to measure the severity and extent of atopic dermatitis (AD) and measures erythema, infiltration, excoriation and lichenification on 4 anatomic regions of the body: head, trunk, upper and lower extremities. The total EASI score ranges from 0 (minimum) to 72 (maximum) points, with the higher scores reflecting the worse severity of AD. EASI-75 responders were the participants who achieved ≥75% overall improvement in EASI score from baseline to Week 16.

Participants were asked the following question: how would a participant rate his itch at the worst moment during the previous 24 hours (for maximum itch intensity on a scale of 0 - 10 [0 = no itch; 10 = worst itch imaginable]). Participants achieving a reduction of ≥4 points from baseline in weekly average of peak daily pruritus NRS score at Week 16 were reported.

Participants were asked to rate their asthma symptoms during the previous week on a 7-point scale as 0=no impairment, 6=maximum impairment. ACQ-5 score was the mean of the 5 questions and range between 0 (totally controlled) and 6 (severely uncontrolled) (a higher score indicated lower asthma control). The ACQ-5 questionnaire was administered only to the participants with a medical history of asthma.
