Outcomes

Primary Outcomes

Double-blind Induction Period: Percentage of Participants Who Achieved Eczema Area and Severity Index (EASI) 75 (>=75% Reduction From Baseline in EASI Score) at Week 16

The EASI score is 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 limbs, and lower limbs. The severity of the clinical signs of AD for each of 4 body regions was scored on a 4-point scale: 0=absent, 1=mild, 2=moderate and 3=severe. The area of AD involvement on each of the 4 anatomic regions was assessed as a percentage by body area: 0=no eruption, 1=1% to 9%, 2=10% to 29%, 3=30% to 49%, 4=50% to 60%, 5=70% to 80% and 6=90% to 100%. The composite index with total score ranged from 0 to 72, where higher scores indicates more severe and or extensive disease.

Time frame: At Week 16

Secondary Outcomes

Double-blind Induction Period: Percentage of Participants Who Achieved Investigator Global Assessment (IGA) Score of 0 or 1 and 2-point Improvement at Week 16

The IGA is an instrument used to globally rate the severity of the participants AD. It is based on a 5-point scale ranging from 0 (clear), 1 (almost clear), 2 (mild), 3 (moderate) and 4 (severe), and a score is selected using descriptors that best describe the overall appearance of the lesions at a given time point. The score is based on an overall assessment of the degree of erythema, papulation/induration, oozing/crusting (minimal, palpable induration and significant induration). Therapeutic response is an IGA score of 0 (clear) or 1 (almost clear).

Time frame: At Week 16

Double-blind Induction Period: Percentage of Participants Who Achieved a 4-point Improvement in Pruritus Numeric Rating Score (NRS) at Week 16

The Pruritus NRS is an 11-point scale used by participants to rate their worst pruritus (itch) severity over the past 24 hours, with 0 indicating "No itch," and 10 indicating "Worst itch imaginable. Higher score indicates more severity.

Time frame: At Week 16

Double-blind Induction Period: Percentage of Participants Who Achieved a 4-point Improvement in Dermatology Life Quality Index (DLQI) at Weeks 2, 4, 8, 12 and 16

The DLQI is a 10-item validated questionnaire completed by the participant or caregiver used to assess the impact of skin disease on the participant's quality of life (QoL during the previous week. The 10 questions cover the following topics: symptoms, embarrassment, shopping and home care, clothes, social and leisure, sport, work or study, close relationships, sex, and treatment. Each question was scored on a 4-point scale (ranged from 0 to 3) where, 0 = not at all, 1= a little, 2= a lot, 3= very much, giving a total score ranging from 0 (not at all) to 30 (very much). A high score is indicative of a poor QoL.

Double-blind Induction Period: Percentage of Participants Who Achieved a 4-point Improvement in Children's Dermatology Life Quality Index (CDLQI) at Weeks 2, 4, 8, 12 and 16

The CDLQI is validated from adolescents younger than age of 16 years, which is based on a set of 10 questions different from those of the DLQI to measure the impact of AD disease on QoL in children during the previous week. Each question is scored as follows: 0=not at all or unanswered, 1 = only a little, 2 = quite a lot and 3 = very much. Question 7 has an added possible response, which was scored as 3. CDLQI equals the sum of the score of each question, ranged from 0 (no impact of skin disease on QoL) to 30 (maximum impact on QoL). Higher scores indicate higher impact on QoL.

Time frame: At Weeks 2, 4, 8, 12 and 16

Double-blind Induction Period: Percentage of Participants Who Achieved a 4- Point Improvement in Skin Pain NRS at Week 16

The Skin Pain NRS is an 11-point scale completed by participants to rate their worst skin pain (example, discomfort or soreness) severity over the past 24 hours, with 0 (indicating "No pain") and 10 (indicating "Worst pain imaginable). Higher scores indicated worse pain.

Time frame: At Week 16

Double-blind Induction Period: Change From Baseline in Body Surface Area (BSA) at Weeks 2, 4, 8, 12 and 16

The BSA assessment estimates the extent of disease or skin involvement with respect to AD and is expressed as a percentage of total body surface. BSA was determined by the Investigator or designee using the participant palm = 1% BSA rule. The participant's palm is measured from the wrist to the proximal interphalangeal and thumb. This higher the BSA %, the more active atopic dermatitis is present. Percent of BSA for a body region = total number of palms in a body region \* % surface area equivalent to 1 palm. Overall percent BSA for an individual is arithmetic mean of % BSA of all 4 body regions and ranges from 0% to 100% with higher values representing greater severity of AD and negative change from baseline indicate no severity.

Double-blind Induction Period: Change From Baseline in Scoring Atopic Dermatitis (SCORAD) at Weeks 8 and 16

SCORAD is a validated clinical tool for assessing the extent and intensity of AD. There are 3 components: A) Surface involvement is assessed as proportion of involved surface area segment by segment by applying the rule of 9s and reported as the sum of all areas, with a score ranging from 0-100. B) Intensity part of the SCORAD consists of 6 items: erythema, oedema, oozing/crusting, excoriation, lichenification, and dryness. Each item graded as: none (0), mild (1), moderate (2), or severe (3). C) Subjective assessment of itch and of sleeplessness is recorded for each symptom using a visual analogue scale (VAS), where 0=no itch (or no sleeplessness) and 10= worst imaginable itch (or sleeplessness), with maximum score of 20. Formula is: A/5+7B/2+C, A: extent (0-100), B: intensity (0-18), C: subjective symptoms (0-20). SCORAD total score ranged from 0 (no disease) to 103 (severe disease). Higher values represent worse outcome and negative change from baseline indicate improvement.

Double-blind Induction Period: Change From Baseline in the Sleep Loss at Week 16 Using Patient-related Outcome (PRO) by Week up to Week 16

Sleep loss was assessed by all participants using a PRO instrument. Participants (and if applicable, with help of parents/caregiver if required) rate their sleep on a 5-point Likert scale (with scores ranging from 0 \[not at all\] to 4 \[unable to sleep at all\]). Higher scores indicated a greater impact and worse outcome; therefore, negative change from baseline indicate less impact.

Double-blind Induction Period: Change From Baseline in Patient-Oriented Eczema Measure (POEM) Total Score at Weeks 4, 8, 12 and 16

The POEM is a 7-item, validated questionnaire completed by the participant (and, if applicable, with help of parents/caregiver if required) to assess disease symptoms. Participants are asked to respond to questions on skin dryness, itching, flaking, cracking, sleep loss, bleeding, and weeping. All answers carry equal weight, with a total possible score ranging from 0 to 28 (answers scored as: No days = 0; 1 to 2 days = 1; 3 to 4 days = 2; 5 to 6 days = 3; every day = 4. Higher scores indicated more severe disease and poor quality of life (QoL); therefore, negative change from baseline indicate improvement in QoL.

Double-blind Induction Period: Change From Baseline in Dermatology Life Quality Index (DLQI) Total Score at Weeks 2. 4, 8, 12 and 16

The DLQI is a 10-item validated questionnaire completed by the participant or caregiver used to assess the impact of skin disease on the participant's QoL during the previous week. The 10 questions cover the following topics: symptoms, embarrassment, shopping and home care, clothes, social and leisure, sport, work or study, close relationships, sex, and treatment. Each question was scored on a 4-point scale (ranged from 0 to 3) where, 0 = not at all, 1= a little, 2= a lot, 3= very much, giving a total score ranging from 0 (not at all) to 30 (very much). A high score is indicative of a poor QoL and negative change from baseline indicate improvement in QoL.
