Outcome Measures

Primary Outcomes (1)

  • Double-blind Treatment Period: Percent Change in Eczema Area and Severity Index (EASI) Score

    EASI evaluates severity of participant's AD based on severity of AD clinical signs and percent (%) of body surface area (BSA) affected. EASI is a composite scoring assessment of the affected area in 4 specific disease characteristics (erythema, thickness \[induration, papulation, edema\], scratching \[excoriation\], and lichenification), which was each assessed on a scale of "0" (absent) through "3" (severe). The EASI Area Score is documented for 4 regions of the body. Region 1: head and neck; Region 2: trunk (including genital area); Region 3: upper limbs; and Region 4: lower limbs (including buttocks), with the area of AD involvement assessed as a percentage by body area and converted to a score of 0 to 6. Total EASI score ranged from 0 to 72; higher score indicated greater severity of AD. Baseline is defined as Day 1 pre-randomization assessments.

    Baseline (Day 1) and Week 12

Secondary Outcomes (16)

  • Double-blind Treatment Period: Percentage of Participants Achieving EASI-75

    Baseline (Day 1) and Week 12

  • Double-blind Treatment Period: Percentage of Participants Achieving a Validated Investigator Global Assessment (vIGA) 0 or 1 Score and a Reduction From Baseline of >= 2 Points

    Baseline (Day 1) and Week 12

  • Double-blind Treatment Period: Percent Change in Weekly Peak Pruritus Numerical Rating Scale (NRS) From an Itch Daily Diary

    Baseline (Day 1) and Week 12

  • Double-blind Treatment Period: Percentage of Participants With Improvement (Reduction) in Peak Pruritus NRS Greater Than or Equal to (>=)3 From an Itch Daily Diary

    Baseline (Day 1) and Week 12

  • Double-blind Treatment Period: Percentage of Participants Achieving EASI-50
