SecondaryPercentage of Participants With Investigator's Global Assessment (IGA) Score = 0-1 at Each VisitUp to 272 weeks (End of Study), "Baseline, Weeks 4, 16, 36, 52, 100, 124, 156, 172, 188, 204, 220, 236, 272 (End of Study)
IGA is an assessment scale used to determine severity of hand and foot 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.
SecondaryPercentage of Participants With Eczema Area and Severity Index (EASI)-75 (≥75% Reduction in EASI Scores From Baseline of the Parent Study) at Each VisitUp to 272 weeks (End of Study), "Baseline, Weeks 4, 16, 36, 52, 100, 124, 156, 172, 188, 204, 220, 236, 272 (End of Study)"
The EASI score was used to measure the severity and extent of atopic dermatitis (AD) and measures erythema, induration, 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.

SecondaryPercentage of Participants With EASI-90 (≥90% Reduction in EASI Scores From Baseline of the Parent Study) at Each VisitUp to 272 weeks (End of Study), "Baseline, Weeks 4, 16, 36, 52, 100, 124, 156, 172, 188, 204, 220, 236, 272 (End of Study)"EASI-90 was defined as \>=90% reduction in EASI scores from baseline of the parent study
SecondaryChange From Baseline in Pruritus Numerical Rating Scale (NRS) in Parent StudyUp to 272 weeks (End of Study), "Baseline, Weeks 1, 4, 16, 36, 52, 100, 124, 156, 172, 188, 204, 220, 236, 252, 272 (End of Study)"
The Pruritus NRS is an assessment tool for patients to report the intensity of their pruritus (itch), using a scale from 0-10, where 0 is no itch and 10 is the worst itch imaginable. Daily peak pruritus NRS score is the worst one between morning and evening scores of the day. Baseline Pruritus NRS is determined based on average of daily peak NRS scores during the 7 days immediately preceding randomization. A minimum of 4 daily scores out of 7 days is required to calculate baseline average score. Weekly worst score is calculated by taking the worst score within the week

SecondaryPercentage of Participants Requiring Rescue Treatment: OverallUp to 272 weeks
SecondaryPercentage of Participants Requiring Rescue Treatment: Systemic TreatmentUp to 272 weeks
SecondaryPercentage of Participants Requiring Rescue Treatment: PhototherapyUp to 272 weeks
SecondaryChanges From Current Study Baseline to Prespecified Time Points Through the End of the Study: Dermatology Life Quality Index (DLQI)Up to 272 weeks (End of Study), "Baseline, Weeks 12, 24, 36, 48, 76, 100, 124, 148, 272 (End of Study)"
The DLQI is a 10-item, validated questionnaire used in clinical practice and clinical trials to assess the impact of AD disease symptoms and treatment on quality of life (QOL). The format is a simple response to 10 items, which assess QOL over the past week, with an overall scoring system of 0 to 30; a high score is indicative of a poor QOL
