| Secondary | Time to Onset of Effect on Pruritus (≥4-point Reduction of Weekly Average of Daily Peak Pruritus NRS From Baseline) | 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?" Due to study discontinuation, not all planned participants were enrolled. For those already enrolled, the study drug was discontinued and participants were transitioned to post-treatment follow-up period. A large amount of data remained uncollected as not all enrolled participants completed all planned study visits and procedures for assessments for some endpoints. Therefore, this endpoint was removed and no data was collected for this outcome measure. | Due to premature discontinuation, all statistical analyses were descriptive, and no hypothesis testing was performed. | Posted | | | | | | Week 16 | | | | ID | Title | Description |

| Secondary | Percent Change From Baseline in SCORing Atopic Dermatitis (SCORAD) at Week 16 | The SCORAD index is a clinical tool for assessing the severity of atopic dermatitis (AD). 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). Due to study discontinuation, not all planned participants were enrolled. For those already enrolled, the study drug was discontinued and participants were transitioned to post-treatment follow-up period. A large amount of data remained uncollected as not all enrolled participants completed all planned study visits and procedures for assessments for some endpoints.

| Secondary | Absolute Change From Baseline in Percent Body Surface Area (BSA) of Atopic Dermatitis (AD) Involvement at Week 16 | BSA affected by AD will be assessed for each section of the body using the rule of nines (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 will be reported as a percentage of all major body sections combined. The proportion assigned to different body regions is different in younger children as compared to older children (head and neck area is assigned a higher proportion in younger children as compared to older children). Due to study discontinuation, not all planned participants were enrolled. For those already enrolled, the study drug was discontinued and participants were transitioned to post-treatment follow-up period. A large amount of data remained uncollected as not all enrolled participants completed all planned study visits and procedures for assessments for some endpoints.
