Registered outcomes5
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Number of Participants With ≥1 Treatment-emergent Adverse Event (TEAE) | Up to 52 weeks | The number of participants with ≥1 TEAE(s) is reported. |
| Secondary | Validated Investigator Global Assessment-Atopic Dermatitis (vIGA-AD) Score of 0 or 1 at Each Assessment | Weeks 4, 12, 24, 36, and 52 | The vIGA-AD is a static evaluation of qualitative overall AD severity. This global assessment scale is an ordinal scale with five severity grades (reported as score of 0 'clear' to 4 'severe' ), with lower scores indicating reduced symptom severity and vice versa. Multiple imputation was used to handle missing data up to Week 24 or 52 for 24- and 52-week cohorts. |
| Secondary | Percentage of Participants With vIGA-AD Success | Weeks 4, 12, 24, 36, and 52 | The percentage of participants with vIGA-AD "success" is presented. Success is defined as vIGA-AD value of 0 or 1 plus a 2-grade improvement from baseline. Multiple imputation was used to handle missing data up to Week 24 or 52 for 24- and 52-week cohorts. |
| Secondary | Change From Baseline in Worst Itch-Numeric Rating Scale (WI-NRS) Score Over Time in Participants ≥12 Years of Age in Parent Study | Weeks 4, 12, 24, 36, and 52 | Change from baseline in WI-NRS score is reported. WI-NRS is a subject-reported severity of itch at its highest intensity during the previous 24-hour period. The scale is from '0 to 10' ("no itch" to "worst imaginable itch"), with lower scores indicating reduced symptom severity and vice versa. |
| Secondary | Percent Change From Baseline in EASI Score | Weeks 4, 12, 24, 36, and 52 | EASI is an instrument to measure the severity and extent of AD. The body is first divided into 4 areas: head (10% of skin), arms (20%), trunk (30%), and legs (40%). Then, the area affected is scored from 0 (0% involvement) to 6 (90%-100% involvement), and severity is scored from 0 ('none') to 3 ('severe'). EASI combines the area affected and severity ratings to get a final composite score ranging from 0 (no disease) to 72 (severe disease). Note that palms and soles were treated as appropriate but were not counted towards any measurements of EASI. |
