Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Percentage change from baseline in Eczema Area and Severity Index Score (EASI) score at Week 4 (Day 28) [ Time Frame: Baseline to Day 28 ]
    EASI is a validated composite scoring system integrating the proportion of the body region (area) involved and the intensity of key signs of atopic dermatitis (AD). The EASI score examines 4 areas of the body and weights them for participants 8 years of age and older as follows: Head/Neck (H) = 0.1, Upper limbs (UL) = 0.2, Trunk (T) = 0.3, and Lower limbs (LL) = 0.4. The severity strata for the EASI are as follows: 0 = clear; 0.1 to 1.0 = almost clear; 1.1 to 7.0 = mild; 7.1 to 21.0 = moderate; 21.1 to 50.0 = severe; 50.1 to 72.0 = very severe. The total EASI score for each region is calculated by multiplying the severity score by the area score, with adjustment for the proportion of the body region to the whole body. The total EASI score ranges from 0 to 72. A higher score indicated worse disease status, and a negative change from baseline indicated improvement.


Secondary Outcome Measures :
  1. Percentage change from baseline in EASI score at each post-baseline study visit [ Time Frame: Baseline to Day 42 ]
  2. Proportion achieving Investigator's Global Assessment-Treatment Success (IGA-TS) defined as Validated Investigator Global Assessment (vIGA) score of 0 or 1 with an improvement in vIGA of at least 2 points from baseline at each post-baseline study visit. [ Time Frame: Baseline to Day 42 ]
    IGA is an assessment scale used to determine severity of atopic dermatitis (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 was an IGA score of 0 (clear) or 1 (almost clear). An IGA responder was defined as a participant achieving an IGA score of 0 to 1 and an IGA score improvement at least 2 from baseline.

  3. Proportion of patients who achieve 50%, 75%, and 90% improvement in EASI score (EASI 50, EASI 75, and EASI 90, respectively) at each post-baseline study visit [ Time Frame: Baseline to Day 42 ]
  4. Change from baseline in vIGA score at each post-baseline study visit [ Time Frame: Baseline to Day 42 ]
  5. Change from baseline in Body Surface Area (BSA) at each post-baseline study visit [ Time Frame: Baseline to Day 42 ]
    BSA is defined as a percentage of the total body (0-100) that is affected by disease

  6. Number of Participants With At Least One Adverse Event (AEs) and as Per Severity [ Time Frame: Baseline to Day 42 ]
    AE is defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related, that occurs after a participant provides informed consent. The severity of AEs was assessed using CTCAE v4.03 Grades 1 through 4.Data are reported for Grade 3 and higher severity for this outcome measure.

  7. Change from baseline in Itch Numerical Rating Scale (PP NRS) from baseline to Day 28 [ Time Frame: Baseline to Day 28 ]
    The Itch NRS is a once-per-24 hours ("daily") participant-reported measure of itch intensity to rate the itching severity because of their AD by selecting a number from 0 (no itch) to 10 (worst imaginable itch) that best describes their worst level of itching in the past 24 hours. The categorical NRS is defined as 0 = None, 1 to 3 = Mild, 4 to 6 = Moderate, and 7 to 10 = Severe.study visit
