E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective of this study is to assess the safety of upadacitinib combined with TCS in adolescent and adult subjects in Japan with moderate to severe AD who are candidates for systemic therapy. |
|
E.2.2 | Secondary objectives of the trial |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Optional biomarker samples (whole blood, serum and plasma) will be collected at specific time points. The objective of research is to analyze samples for biomarkers that will help to understand AD, related conditions, and response to treatment with upadacitinib or similar compounds. |
|
E.3 | Principal inclusion criteria |
- Subject must be at least ≥ 12 years old and ≤ 75 years old at Screening; - Body weight ≥ 40 kg at the Baseline Visit for subjects between ≥ 12 and < 18 years of age. - Chronic AD with onset of symptoms at least 3 years prior to Baseline and subject meets Hanifin and Rajka criteria. - Subject has applied a topical emollient (moisturizer) twice daily for at least 7 days before the Baseline Visit. - EASI score ≥ 16, vIGA-AD score ≥ 3, ≥ 10% body surface area (BSA) of AD involvement, and weekly average of daily worst pruritus numerical rating scale (NRS) ≥ 4. - inadequate response to TCS or topical calcineurin inhibitors (TCIs) OR documented systemic treatment for AD within 6 months prior to the Baseline Visit. |
|
E.4 | Principal exclusion criteria |
- prior exposure to any JAK inhibitor. - prior exposure to dupilumab. - have ≥ 30% of AD lesional surface involvement at Baseline that cannot be safely treated with medium or higher potency TCS (e.g., areas of skin atrophy, face, groin, intertriginous areas). - systemic therapy for AD within 4 weeks - targeted biologic therapy within 12 weeks - topical treatments (except topical emollient treatment) within 7 days

E.5 End points |
E.5.1 | Primary end point(s) |
Safety endpoints include: - Treatment emergent adverse events (TEAEs); - Serious adverse events (SAEs), - Adverse events (AEs) of special interest (AESI); - AEs leading to discontinuation; - Vital signs and laboratory tests. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Through the 30 day follow-up visit after Week 160. |
|
E.5.2 | Secondary end point(s) |
- Proportion of subjects achieving validated Investigator Global Assessment scale for Atopic Dermatitis (vIGA-AD) 0 or 1 with at least 2 grades of reduction from Baseline; - Proportion of subjects achieving a 50%/75%/90% reduction in Eczema Area Severity Index (EASI 50/75/90) from Baseline; - Change and percent change from Baseline in EASI; - Proportion of subjects achieving an improvement (reduction) in worst pruritus Numerical Rating Scale (NRS) ≥ 4 from Baseline; - Change and percent change from Baseline in worst pruritus NRS. - Pharmacokinetic endpoint: using the data available from these subjects, a nonlinear mixed-effects modeling approach will be used to estimate the population central values and the empirical Bayesian estimates of the individual values of upadacitinib oral clearance (CL/F) and volume of distribution (V/F). |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
The secondary end points are being collected up to week 160 except for Pharmacokinetic endpoint which is collected through week 16. |
