Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants Achieving Eczema Area and Severity Index (EASI) Score Less Than or Equal to (<=) 7 at Week 24	The EASI is used to assess the severity and extent of AD; it is a composite index with scores ranging from 0 to 72, with higher values indicating more severe and or extensive disease. The severity of erythema, induration/papulation, excoriation, and lichenification will be assessed by the Investigator or trained designee on a scale of 0 (absent) to 3 (severe) for each of the 4 body areas: head/neck, trunk, upper limbs, and lower limbs, with half points allowed. In addition, the extent of AD involvement in each of the 4 body areas will be assessed as a percentage by body area of head/neck, trunk, upper limbs, and lower limbs, and converted to a score of 0 (0%), 1 (0 to 9%), 2 (10 to 29%), 3 (30 to 49%), 4 (50 to 69%), 5 (70 to 89%) and 6 (90 to 100%).	Baseline, Week 24
Secondary	Percentage of Participants Achieving EASI Score <=7, <=5, and <=3	The EASI is used to assess the severity and extent of AD; it is a composite index with scores ranging from 0 to 72, with higher values indicating more severe and or extensive disease. The severity of erythema, induration/papulation, excoriation, and lichenification will be assessed by the Investigator or trained designee on a scale of 0 (absent) to 3 (severe) for each of the 4 body areas: head/neck, trunk, upper limbs, and lower limbs, with half points allowed. In addition, the extent of AD involvement in each of the 4 body areas will be assessed as a percentage by body area of head/neck, trunk, upper limbs, and lower limbs, and converted to a score of 0 (0%), 1 (0 to 9%), 2 (10 to 29%), 3 (30 to 49%), 4 (50 to 69%), 5 (70 to 89%) and 6 (90 to 100%).	Baseline up to Week 24
Secondary	Percentage of Participants Achieving EASI 50, 75, and 90 Reduction From Baseline	The EASI is used to assess the severity and extent of AD; it is a composite index with scores ranging from 0 to 72, with higher values indicating more severe and or extensive disease. EASI 50 is defined as 50% reduction from baseline in the EASI score. EASI 75 is defined as 75% reduction from baseline in the EASI score. EASI 90 is defined as 90% reduction from baseline in the EASI score.	Baseline up to Week 24
Secondary	Percentage Change From Baseline in EASI Total Score	The EASI is used to assess the severity, extent of AD clinical signs and percentage (%) of 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]) on 4-point scale: 0= absent; 1= mild; 2= moderate; 3= severe. EASI area score is based upon % BSA with AD in 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 ranges from 0 to 72, where higher scores indicate greater severity of AD.	Baseline up to Week 24
Secondary	Mean EASI Score	The EASI is used to assess the severity and extent of AD; it is a composite index with scores ranging from 0 to 72, with higher values indicating more severe and or extensive disease.	Baseline up to Week 24
Secondary	Percentage of Participants with an Investigator Global Assessment (IGA) Score of 0 or 1 and a Reduction Greater Than or Equal to (>=2) Points	The IGA is an instrument used to globally rate the severity of the participants's 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).	Baseline up to Week 24
Secondary	Percent Change From Baseline in Body Surface Area (BSA)	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 will be 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.	Baseline up to Week 24
Secondary	Percentage Change From Baseline in Scoring Atopic Dermatitis (SCORAD)	SCORAD is a validated clinical tool for assessing the extent and intensity of AD. There are 3 components: surface involvement, intensity part and subjective assessment. Surface involvement is assessed as proportion of involved surface area segment by segment by applying the rule of 9s. Intensity part of the SCORAD consists of 6 items: erythema, oedema, oozing/crusting, excoriation, lichenification, and dryness. Each item is graded as follows: none (0), mild (1), moderate (2), or severe (3) (for a maximum of 18 total points). Subjective assessment of itch and of sleeplessness is recorded for each symptom using a VAS, where 0 is no itch (or sleeplessness) and 10 is the worst imaginable itch (or sleeplessness), for maximum possible score of 20. The score ranges from 0 to 103, with higher values indicating a more extensive and/or severe condition.	Baseline up to Week 24
Secondary	Percentage of Participants Achieving SCORAD 50, 75, and 90	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. SCORAD 50 is defined as 50% reduction in SCORAD from baseline. SCORAD 75 is defined as 75% reduction in SCORAD from baseline. SCORAD 90 is defined as 90% reduction in SCORAD from baseline.	Baseline up to Week 24
Secondary	Percentage of Participants With a Face IGA Score of 0 or 1 and a Reduction >=2 Points	The IGA is an instrument used to globally rate the severity of the participants's 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).	Baseline up to Week 24
Secondary	Percentage Change From Baseline in Modified Total Lesion Symptom Score (mTLSS)	mTLSS combines an evaluation of hand eczema lesions severity including 6 key signs (erythema, desquamation, lichenification/hyperkeratosis, vesiculae, oedema, fissures) and the intensity of pruritus and pain. The seven features of AD of the hand (erythema, scaling, lichenification/hyperkeratosis, vesiculation, oedema, fissures, pruritus/pain) form the composite scale of mTLSS' strength and each one of them scores from 0 (mild) to 3 (severe). The scores is summed, extending from a base estimation of 0 (no signs or symptoms) to the most extreme of 21 (more serious disease).	Baseline up to Week 24
Secondary	Percentage of Participants with Pruritus Numerical Rating Scale (NRS) >=4 at Baseline Achieving Pruritus NRS score <=4	The Pruritus NRS is an 11-point scale used by participants to rate their worst itch severity over the past 24 hours, with 0 indicating "No itch," and 10 indicating "Worst itch imaginable. Assessments will be recorded by the participant using an electronic Dairy (eDiary).	Baseline up to Week 24
Secondary	Percentage of Participants With Pruritus NRS >=4 at Baseline Achieving >=4-Point Improvement in Pruritus NRS	The Pruritus NRS is an 11-point scale used by participants to rate their worst itch severity over the past 24 hours, with 0 indicating "No itch," and 10 indicating "Worst itch imaginable. Assessments will be recorded by the participant using an eDiary.	Baseline up to Week 24
Secondary	Percentage Change From Baseline in Pruritus NRS score	The Pruritus NRS is an 11-point scale used by participants to rate their worst itch severity over the past 24 hours, with 0 indicating "No itch," and 10 indicating "Worst itch imaginable. Assessments will be recorded by the participant using an eDiary.	Baseline up to Week 24
Secondary	Change From Baseline in Dermatology Life Quality Index (DLQI)/Children Dermatology Life Quality Index cDLQI	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 is scored from 0=not at all, 1=a little, 2=a lot, and 3=very much, giving a total score ranging from 0 to 30. High score is indicative of a poor QoL. 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. The answers to the questions are generally scored on a 4-point scale from 0=not at all or question unanswered, 1=only a little, 2=quite a lot, 3=very much. CDLQI is calculated by summing the score of each question resulting in 0 to 30. Higher the score, the more impairment of the child's life is experienced.	Baseline up to Week 24

Secondary	Itch Controlled Days Questionnaire Using PRO	The Itch Controlled Days questionnaire is a validated PRO composed of a set of questions that describe several parameters related to the course of pruritus over the course of the day. Specifically, the scale assesses itch presence and severity, the need to scratch, and sleep quality and sleep disturbances due to itching, rated on scales of 0 to 10. The questionnaire also assesses itch duration and temporal patterns associated with itch over a 24-hour period.	Baseline up to Week 24
Secondary	Participant and Investigator Completed Treatment Satisfaction Questionnaires Version 9 (TSQM-9)	The TSQM-9 is a conceptually and psychometrically valid PRO instrument that assesses four key dimensions of treatment satisfaction: effectiveness, side effects, convenience, and global satisfaction, enabling comparisons across medication types and diseases. The TSQM-9 domain scores range from 0 to 100 with higher scores representing higher satisfaction on that domain.	Baseline up to Week 24
Secondary	Participant and Investigator-Reported Satisfaction Questionnaire	The Participant-Reported Satisfaction Questionnaire asks, "How satisfied are you with this treatment's ability to treat your skin condition?". The response options range from 1 (not satisfied) to 5 (completely satisfied). Higher score representing higher satisfaction on that domain.	Baseline up to Week 24
Secondary	Patient Global Assessment of Disease Status (PGADS)	Patient Global Assessment of Disease Status (PGADS) measures static disease severity. Participants are asked "Considering all the ways in which your eczema affects you, indicate how well you are doing" and rate their overall well-being based on a 5-point Likert scale which ranged from 0 (extremely poor) to 100 (excellent). Higher score indicates better outcome.	Baseline up to Week 24
Secondary	Percentage of Participants With Treatment-emergent Adverse Events (TEAEs), Serious Adverse Events (SAEs), Related AEs, AEs Leading to Study Treatment Discontinuation, and Adverse Events of Special Interest (AESIs)	An AE is defined as any untoward medical occurrence in a clinical trial participant, regardless of the administration of the IMP and its causal relationship to it. An AE can therefore be any unfavourable/unintended medical occurrence during the participation in the trial, including deterioration of a pre-existing medical condition, an abnormal value in a laboratory assessment, ECG abnormality, or an abnormal finding in the physical examination. An SAE is an AE, which falls into any of the following categories: death, is life-threatening, requires in-patient hospitalisation or prolongs existing hospitalisation, persistent or significant disability or incapacity, congenital anomaly or birth defect, or any other medically important event that may jeopardise the participant or may require intervention to prevent one of the other above outcomes. The following treatment-emergent AEs are being designated as AESIs: conjunctivitis, herpes simplex or zoster infection and parasitic infections.	Baseline up to follow-up (Week 28)
