Primary | Percentage of Participants With Investigator's Global Assessment (IGA) 0 or 1 (and Reduction From Baseline of =2 Points) at Week 16 | 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). Participants with IGA "0" or "1" and a reduction from baseline of =2 points at Week 16 were reported. [Values after first rescue treatment used were set to missing. Participants with missing score at week 16 were considered as a non-responder. Participant considered non-responder after rescue treatment use. Efficacy analyses were based on the treatment allocated at randomization (as randomized).] | Baseline and Week 16 | |
Primary | Percentage of Participants With Eczema Area and Severity Index (EASI)-75 (=75% Improvement From Baseline) at Week 16 | The EASI score was used to measure the severity and extent of AD and measures 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. EASI--75 responders were the participants who achieved =75% overall improvement in EASI score from baseline to Week 16. [Values after first rescue treatment used were set to missing. Participants with missing score at week 16 were considered as a non-responder. Participant considered nonresponder after rescue treatment use. Efficacy analyses were based on the treatment allocated at randomization (as randomized).] | Baseline and Week 16 | |
Secondary | Percent Change From Baseline in EASI Score at Week 16 | The Eczema Area and Severity Index (EASI) score was used to measure the severity and extent of AD and measures 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. [Values after first rescue treatment use were set to missing and participants with missing EASI score at Week 16 were considered as non-responders.] | Baseline and Week 16 | |
Secondary | Percent Change From Baseline in Weekly Average of Daily Peak Pruritus Numerical Rating Scale (NRS) Score at Week 16 | Peak Pruritus NRS is an assessment tool used by subjects to report intensity of pruritus (itch) during a 24-hour recall period. Participants were asked the following question: For maximum itch intensity: "On a scale of 0 to 10, with 0 being 'no itch' and 10 being the 'worst itch imaginable,' how would you rate your itch at the worst moment during the previous 24 hours?" For post-baseline NRS, the mean weekly NRS was calculated as the prorated average of the reported daily NRS within the week. For example, if there were 3 scores in a week, the prorated average = (score1 + score2 + score3) /3. [Values after first rescue treatment were set to missing and participants with missing peak NRS at Week 16 were counted as non-responders.] | Baseline and Week 16 | |
Secondary | Percentage of Participants With Improvement (Reduction =3 Points) of Weekly Average of Daily Peak Pruritus NRS From Baseline to Week 16 | Peak Pruritus NRS is an assessment tool used by participants to report intensity of pruritus (itch) during a 24-hour recall period. Participants were asked the following question: For maximum itch intensity: "On a scale of 0 to 10, with 0 being 'no itch' and 10 being the 'worst itch imaginable,' how would you rate your itch at the worst moment during the previous 24 hours?" [For this endpoint, participants achieving a reduction of =3 points from baseline in weekly average of peak daily pruritus NRS score at Week 16 were reported. Values after first rescue treatment were set to missing and participants with missing peak NRS at Week 16 were counted as non-responders.] | Baseline to Week 16 | |

[For this endpoint, participants achieving a reduction of =4 points from baseline in weekly average of peak daily pruritus NRS score at Week 16 were reported. Values after first rescue treatment were set to missing and participants with missing peak NRS at Week 16 were counted as non-responders.] | Baseline to Week 16 | |
Secondary | Percentage of Participants With EASI-50 (=50% Improvement From Baseline) at Week 16 | The EASI score was 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. EASI-50 responders were the participants who achieved =50% overall improvement in EASI score at Week 16. [Values after first rescue treatment used were set to missing. Participants with missing value at Week 16 were considered as a non-responder]. | Baseline and Week 16 | |

Participants were asked the following question: For maximum itch intensity: "On a scale of 0 to 10, with 0 being 'no itch' and 10 being the 'worst itch imaginable,' how would you rate your itch at the worst moment during the previous 24 hours?" [For this endpoint, subjects achieving a reduction of =4 points from baseline in weekly average of peak daily pruritus NRS score at Week 16 were reported. Values after first rescue treatment were set to missing and participants with missing peak NRS at Week 16 were counted as non-responders.] | Baseline up to Week 16 | |
Secondary | Change From Baseline in Percent Body Surface Area (BSA) at Week 16 | BSA affected by AD was assessed for each section of the body (the possible highest score for each region was: head and neck [9%], anterior trunk [18%], back [18%], upper limbs [18%], lower limbs [36%], and genitals [1%]). It was reported as a percentage of all major body sections combined. | Baseline and Week 16 | |
Secondary | Percent Change From Baseline in Scoring Atopic Dermatitis (SCORAD) Score at Week 16 | The SCORAD index is a clinical tool for assessing the severity of atopic dermatitis. Extent and intensity of eczema as well as subjective signs (insomnia, etc.) are assessed and scored. Total score ranges from 0 (absent disease) to 103 (severe disease). | Baseline and Week 16 | |
Secondary | Change From Baseline in Children's Dermatology Life Quality Index (CDLQI) Total Score at Week 16 | The CDLQI is a 10-item questionnaire used to measure how much a participant's skin problem had affected the participant's quality of life (QOL) over a recall period of the past week. The questionnaire consists of 10 items. For each item the scale is rated as follows: 0 = Not at all = Not relevant; 1 = Only a little; 2 = Quite a lot; 3 = Very much = Yes = Prevents school. The CDLQI total score is the sum of the score of each question with a maximum of 30 and a minimum of 0. The higher the score, the greater the impact is on the QOL. | Baseline and Week 16 | |
Secondary | Change From Baseline in Patient Oriented Eczema Measure (POEM) at Week 16 | The POEM is a 7-item, validated questionnaire used in clinical practice and clinical trials to assess disease symptoms in children and adults with atopic eczema. The format is subject response to 7 items (dryness, itching, flaking, cracking, sleep loss, bleeding, and weeping) based on symptom frequency during the past week (ie, 0 = 'no days', 1 = '1 to 2 days', 2 = '3 to 4 days', 3 = '5 to 6' days, and 4 = 'every day'). The total score is the sum of the 7 items which is ranged from 0 to 28; a high score is indicative of a poor quality of life (QOL). | Baseline and Week 16 | |
Secondary | Change From Baseline in Weekly Average of Daily Peak Pruritus NRS at Week 16 | Peak Pruritus NRS is an assessment tool used by participants to report intensity of pruritus (itch) during a 24-hour recall period. Particpants were asked the following question for maximum itch intensity: "On a scale of 0 to 10, with 0 being 'no itch' and 10 being the 'worst itch imaginable,' how would you rate your itch at the worst moment during the previous 24 hours?" For post-baseline NRS, the mean weekly NRS was calculated as the prorated average of the reported daily NRS within the week. For example, if there were 3 scores in a week, the prorated average = (score1 + score2 + score3)/ 3. | Baseline and Week 16 | |
Secondary | Percent Change From Baseline in Weekly Average of Daily Peak Pruritus NRS at Week 4 | Peak Pruritus NRS is an assessment tool used by participants to report intensity of pruritus (itch) during a 24-hour recall period. Participants were asked the following question for maximum itch intensity: "On a scale of 0 to 10, with 0 being 'no itch' and 10 being the 'worst itch imaginable,' how would you rate your itch at the worst moment during the previous 24 hours?" For post-baseline NRS, the mean weekly NRS was calculated as the prorated average of the reported daily NRS within the week. For example, if there were 3 scores in a week, the prorated average = (score1 + score2 + score3)/ 3. | Baseline and Week 4 | |
Secondary | Change From Baseline in Total Hospital Anxiety and Depression Scale (HADS) at Week 16 | The HADS is 14-item questionnaire with two subscales: anxiety & depression. Each item is rated on a 4-point scale (0-3). A person could score between 0 & 21 for each subscale (anxiety & depression). A high score is indicative of a poor state. Scores of 11 or more on either subscale are considered a 'definite case' of psychological morbidity, while scores of 8 to 10 represents 'probable case' & 0 to 7 'not a case'. The total score was the sum of the 2 sub-scores; therefore, the full range of possible values for the reported data is 0-42. | Baseline and Week 16 | |
Secondary | Percentage of Participants With Improvement (Reduction =4 Points) of Weekly Average of Daily Peak Pruritus NRS From Baseline at Week 4 | Peak Pruritus NRS is an assessment tool used by participants to report intensity of pruritus (itch) during a 24-hour recall period. Participants were asked the following question for maximum itch intensity: "On a scale of 0 to 10, with 0 being 'no itch' and 10 being the 'worst itch imaginable,' how would you rate your itch at the worst moment during the previous 24 hours?" For post-baseline NRS, the mean weekly NRS was calculated as the prorated average of the reported daily NRS within the week. For example, if there were 3 scores in a week, the prorated average = (score1 + score2 + score3)/ 3. | Baseline and Week 4 | |
Secondary | Percentage of Participants With Skin-infection Treatment Emergent Adverse Events (TEAEs) (Excluding Herpetic Infections) Through Week 16 | Any untoward medical occurrence in a subject who received investigational medicinal product (IMP) was considered an AE without regard to possibility of causal relationship with this treatment. Treatment-emergent adverse events (TEAEs) were defined as AEs that developed or worsened or became serious during on-treatment period (time from the first dose of study drug up to the end of study (Week 16)). A serious adverse event (SAE) was defined as any untoward medical occurrence that resulted in any of the following outcomes: death, life-threatening, required initial or prolonged in-patient hospitalization, persistent or significant disability/incapacity, congenital anomaly/birth defect, or considered as medically important event. Any TEAE included participants with both serious and non-serious AEs. | Baseline through Week 16 | |
