Primary Outcome Measures
NameTimeMethod
Percent Change From Baseline in Eczema Area and Severity Index (EASI) Total Score at Week 6: Multiple ImputationBaseline, Week 6

EASI evaluates severity of participant's AD (excluded scalp, palms, soles) based on severity of AD clinical signs and % of body surface area (BSA) affected. Severity of clinical signs of AD (erythema, induration/papulation, excoriation and lichenification) scored separately for each of 4 body regions(head and neck, upper limbs, trunk \[including axillae and groin\] and lower limbs \[including buttocks\]) on4-point scale: 0= absent; 1= mild; 2= moderate; 3= severe. EASI area score was based upon % BSA with AD in each 4 body region: 0 (0%), 1 (\>0 to \<10%), 2 (10 to \<30%), 3 (30 to \<50%), 4 (50 to \<70%), 5 (70 to \<90%) and 6 (90 to 100%). Total EASI score =0.1\*Ah\*(Eh+Ih+Exh+Lh) + 0.2\*Au\*(Eu+Iu+ExU+Lu) + 0.3\*At\*(Et+It+Ext+Lt) + 0.4\*Al\*(El+Il+Exl+Ll); A = EASI area score; E = erythema; I = induration/papulation; Ex = excoriation; L = lichenification; h = head and neck; u = upper limbs; t = trunk; l = lower limbs. Total EASI score ranged from 0.0 to 72.0, higher scores = greater severity of AD.

Percentage of Participants Achieving Investigator's Global Assessment (IGA) Score Clear (0) or Almost Clear (1) and a Reduction From Baseline of Greater Than or Equal to ( >=2) Points at Week 6: Non-responder ImputationBaseline, Week 6

IGA assesses severity of participant's AD on a 5 point scale. 0= clear, no inflammatory signs of AD; 1= almost clear, AD not fully cleared- light pink residual lesions (except post-inflammatory hyperpigmentation), just perceptible erythema, papulation/induration lichenification, excoriation, and no oozing/crusting; 2= mild AD with light red lesions, slight but definite erythema, papulation/induration, lichenification, excoriation and no oozing/crusting; 3= moderate AD with red lesions, moderate erythema, papulation/induration, lichenification, excoriation and slight oozing/crusting and 4= severe AD with deep dark red lesions, severe erythema, papulation/induration, lichenification, excoriation and moderate to severe oozing/crusting. Higher scores indicating more severity of AD. Assessment excluded soles, palms and scalp.

Percentage of Participants Achieving >=2 Points Reduction in Peak Pruritus Numerical Rating Scale (PP-NRS) From Baseline at Weeks 1, 2, 3, 4 and 6: Non-responder ImputationBaseline, Weeks 1, 2, 3, 4 and 6

The severity of itch (pruritus) due to AD was assessed using a horizontal NRS. Participants at specified time points were asked the following question: "How would you rate your itch due to AD at the worst moment during the previous 24 hours?" The scale ranged from 0-10, where 0= no itch and 10= worst itch imaginable. Higher scores indicated worse itch.

Percentage of Participants Achieving >=4 Points Reduction in Peak Pruritus Numerical Rating Scale (PP-NRS) From Baseline at Weeks 1, 2, 3, 4, 6 and Follow-up Visit: Non-responder ImputationBaseline, Weeks 1, 2, 3, 4, 6 and follow up visit (28 days after last dose of study drug = maximum up to Day 71)

The severity of itch (pruritus) due to AD was assessed using a horizontal NRS. Participants at specified time points were asked the following question: "How would you rate your itch due to AD at the worst moment during the previous 24 hours?" The scale ranged from 0-10, where 0= no itch and 10= worst itch imaginable. Higher scores indicated worse itch.

Percent Change From Baseline in Affected Body Surface Area (BSA) at Weeks 1, 2, 3, 4, 6 and Follow-up VisitBaseline, Weeks 1, 2, 3, 4, 6 and follow up visit (28 days after last dose of study drug = maximum up to Day 71)

4 body regions were evaluated: head and neck, upper limbs, trunk (including axillae and groin) and lower limbs (including buttocks). Scalp, palms and soles were excluded. BSA was calculated using handprint method. Number of handprints (size of participant's full palmer hand) fitting in the affected area of a body region was estimated. Maximum number of handprints were 10 for head and neck, 20 for upper limbs, 30 for trunk and 40 for lower limbs. Surface area of body region equivalent to 1 handprint: 1 handprint was equal to 10% for head and neck, 5% for upper limbs, 3.33% for trunk and 2.5% for lower limbs. Percent BSA for a body region was calculated as = total number of handprints in a body region \* % surface area equivalent to 1 handprint. Overall % BSA for an individual: arithmetic mean of % BSA of all 4 body regions, ranged from 0 to 100%, with higher values representing greater severity of AD.

Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)Baseline (Day 1) up to at least 28 days after last dose of study drug (approximately up to Week 11)

An AE was any untoward medical occurrence in a participant who received investigational product without regard to possibility of causal relationship. SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly; medically important events. Treatment-emergent were events between first dose of investigational product and up to 28 days after the last dose of investigational product that were absent before treatment or that worsened relative to pretreatment state. AEs included both SAEs and all non-SAEs.
