Percent Change From Baseline in Eczema Area and Severity Index (EASI) at Week 24
EASI is a composite score ranging from 0 to 72.The severity of erythema, induration/papulation, excoriation, and lichenification was assessed 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. Higher scores indicate worse outcome.
Time frame: From Baseline to Week 24
Number of Participants Achieving Pruritus Categorical Scale (PCS) Success (Defined as a Weekly Prorated Rounded Average PCS ≤1 [None - Mild]) at Week 24
The 4-point pruritus categorical scale was provided in their local language for the participants to report the intensity of their pruritus. Overall itching was scored as 0 for absence of pruritus and 3 for severe pruritus (bothersome itching/scratching that disturbs sleep). Higher scores indicate worse outcome.
Time frame: Week 24
Number of Participants With an Improvement of Weekly Average Peak Pruritus Numeric Rating Scale (NRS) ≥4 at Each Timepoint up to Week 24
Pruritus NRS is a scale that was used by the participants to report the intensity of their pruritus (itch) during the last 24 hours. For maximum itch intensity: the scores were provided on a scale of 0 to 10, with 0 being 'no itch' and 10 being 'worst itch imaginable'. Higher scores indicate worse outcome.
Time frame: From Week 1 to Week 24
Percent Change From Baseline in SCORing Atopic Dermatitis (SCORAD) at Week 24
SCORAD ranges from 0 to 103 and has three components: extent (body surface area \[BSA\]), signs, and symptoms of AD. The severity of the 6 signs of AD (erythema/darkening, edema/papulation, oozing/crusting, excoriation, lichenification/prurigo and dryness), was assessed, each on a scale ranging from 0 (none) to 3 (severe).The component of extent corresponded to the extent of BSA affected by atopic dermatitis.The BSA involvement of AD was assessed for each part of the body (the possible highest score for each region is: head and neck \[9%\], anterior trunk \[18%\], back \[18%\], upper limbs \[18%\], lower limbs \[36%\], and genitals \[1%\]), and was reported as a percentage of all major body sections combined. Participants were also asked to evaluate their symptoms of pruritus and sleep loss (average for the last 3 days/nights), each evaluated on a Visual analog scale (VAS) from 0 to 10. Higher scores indicate worse outcome.

Absolute Change From Baseline in SCORing Atopic Dermatitis (SCORAD) at Week 24
SCORAD ranges from 0 to 103 and has three components: extent (body surface area \[BSA\]), signs, and symptoms of AD. The severity of the 6 signs of AD (erythema/darkening, edema/papulation, oozing/crusting, excoriation, lichenification/prurigo and dryness), was assessed, each on a scale ranging from 0 (none) to 3 (severe).The component of extent corresponded to the extent of BSA affected by atopic dermatitis.The BSA involvement of AD was assessed for each part of the body (the possible highest score for each region is: head and neck \[9%\], anterior trunk \[18%\], back \[18%\], upper limbs \[18%\], lower limbs \[36%\], and genitals \[1%\]), and was reported as a percentage of all major body sections combined. Participants were also asked to evaluate their symptoms of pruritus and sleep loss (average for the last 3 days/nights), each evaluated on a Visual analog scale (VAS) from 0 to 10. Higher scores indicate worse outcome.
Time frame: Baseline, Week 24
Percent Change From Baseline in Weekly Average Sleep Disturbance Numeric Rating Scale (NRS) at Week 24
The sleep disturbance NRS is a scale used by the participants to report the degree of their sleep loss related to AD. Participants were asked the following questions in their local language: how would you rate your sleep last night?: On a scale of 0 to 10, with 0 being 'no sleep loss related to signs/symptoms of AD' and 10 being 'I cannot sleep at all due to the signs/symptoms of AD'. Higher scores indicate worse outcome.
