Primary Outcome Measures :
- Percent change from Baseline in Eczema Area and Severity Index (EASI) at Week 16 [ Time Frame: Baseline, Week 16 ]The EASI score is used to measure the severity and extent of AD and measured 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
Secondary Outcome Measures :
- Proportion of patients achieving validated Investigator's Global Assessment (vIGA) response of 0 (clear) or 1 (almost clear) at Week 16 [ Time Frame: 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).
- Proportion of patients with EASI 50, 75 and 90 at Week 16 [ Time Frame: Week 16 ]EASI scores range from 0 to 72 (severe)The EASI responder is defined as a participant who achieves a ≥50% improvement (EASI 50), ≥75% improvement (EASI 75), or ≥90% improvement (EASI 90) from baseline in the EASI score.
- Proportion of patients with EASI <7 at Week 16 [ Time Frame: Week 16 ]EASI scores range from 0 to 72 (severe)
- Percent Change in EASI score from Baseline over time [ Time Frame: Baseline, Week 16 ]EASI scores range from 0 to 72 (severe)
- Absolute and percent change in Pruritus Numerical Rating Scale (P-NRS) over time [ Time Frame: Baseline, Week 16 ]The P-NRS is an 11-point scale used by patients to assess their worst itch severity over the past 24 hours, with 0 indicating no itch and 10 indicating the worst itch imaginable. Pruritus assessments will be recorded daily by the patient using an electronic diary
- Proportion of patients achieving a 4-point reduction in P-NRS [ Time Frame: Baseline, Week 16 ]The P-NRS is an 11-point scale used by patients to assess their worst itch severity over the past 24 hours, with 0 indicating no itch and 10 indicating the worst itch imaginable. Pruritus assessments will be recorded daily by the patient using an electronic diary.
- Change in Body Surface Area (BSA) affected with AD [ Time Frame: Baseline, Week 16 ]BSA ranges from 0% to 100 % with higher values representing greater extent of AD.
- Change in SCORing Atopic Dermatitis (SCORAD) from Baseline to Week 16 [ Time Frame: Baseline, Week 16 ]The SCORAD is a validated measure of the extent and severity of atopic dermatitis lesions, along with subjective symptoms. The score ranges from 0 to 103, with higher values indicating a more extensive and/or severe condition.
- Change in Dermatology Life Quality Index (DLQI) from Baseline to Week 16 [ Time Frame: Baseline, Week 16 ]The DLQI is a 10-item, validated questionnaire used in clinical practice and clinical trials to assess the patient's perception of the impact of AD disease symptoms and treatment on their quality of life (QoL). The 10 questions assess QoL over the past week, with an overall scoring of 0 (absent disease) to 30 (severe disease). A high score is indicative of a poor QoL.
- Change in Patient-Oriented Eczema Measure (POEM) from Baseline to Week 16 [ Time Frame: Baseline to Week 16 ]The POEM is a 7-item questionnaire that assesses disease symptoms (dryness, itching, flaking, cracking, sleep loss, bleeding and weeping) with a scoring system of 0 (absent disease) to 28 (severe disease) (high score indicative of poor quality of life [QOL])
- Change in the European Quality of Life-5 Dimensions-5 Levels (EQ-5D-5L) Index Score United States and United Kingdom Algorithm from Baseline to Week 16 [ Time Frame: Baseline, Week 16 ]The EQ-5D-5L is a 2-part measurement. The second part is assessed using a VAS that ranges from 0 to 100 millimeter (mm), where 0 is the worst health you can imagine and 100 is the best health you can imagine
- Change in Hospital Anxiety Depression Scale (HADS) from Baseline to Week 16 [ Time Frame: Baseline to Week 16 ]HADS is a 14-item scale. Seven of the items relate to anxiety and seven items relate to depression. Each item on the questionnaire is scored from 0 (minimum score) - 3 (maximum score) and this means that a person can score between 0 (no symptoms) and 21 (severe symptoms) for either anxiety or depression. The total HADS score or subscores may be regarded as a global measure of psychological distress; higher scores indicate greater levels of anxiety or depression.
- Absolute and percent change in sleep disturbance SD-NRS over time [ Time Frame: Baseline to Week 16 ]The SD-NRS is an 11-point scale used by patients to assess their sleep disturbance severity over the past 24 hours, with 0 indicating no or minimal sleep disturbance and 10 indicating the worst imaginable sleep disturbance. SD-NRS assessments will be recorded daily by the patient using an electronic diary.
- Proportion of patients achieving a 4-point reduction in SD-NRS from Baseline to at Week 16 [ Time Frame: Baseline to Week 16 ]
- Number of Treatment-Emergent Adverse Events (TEAEs) and Treatment-Emergent Serious Adverse Events (TESAEs) from study drug administration (Day 1) to Week 28 [ Time Frame: : Baseline to Week 28 ]TEAEs are defined as AEs that develop or worsen or become serious during on-treatment period (time from the first dose of study drug until Week 28. A TESAE is defined as any untoward medical occurrence that results in any of the following outcomes: death, life-threatening, requires initial or prolonged in-patient hospitalization, persistent or significant disability/incapacity, congenital anomaly/birth defect, or is considered as medically important event. Any TEAE includes participants with both serious and non-serious AEs.
