Summary

This study tests whether upadacitinib (Rinvoq), a daily pill already used in older patients, can safely improve moderate to severe eczema in children aged 2 to 11 in Japan. About 99 kids will receive either the drug or a placebo, plus a steroid cream, for up to a year. Researchers will measure skin clearing and watch for side effects.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
upadacitinib (Rinvoq) taken as a tablet or oral solution
What this could lead to
If it works, this could offer a new treatment option for children with stubborn eczema that isn't controlled by creams alone.
What could go wrong
This is a relatively small, early-phase study in Japan only. Upadacitinib has known risks like infections and allergic reactions, and it's not yet proven for this age group.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * A minimum weight of 10 kg and weight and height ≥ -2.0 SD for their age according to Japanese standard growth charts at the Baseline visit. * Atopic Dermatitis (AD), according to Hanifin and Rajka criteria, with onset of symptoms at least 6 months prior to Baseline. * Eczema Area and Severity Index (EASI) score ≥ 16; validated Investigator Global Assessment scale for Atopic Dermatitis (vIGA-AD) score ≥ 3; ≥ 10% body surface area (BSA) of AD involvement at the Baseline visit; and Baseline weekly average of daily WIS or WSI-NRS ≥ 4. * Participant has applied a topical, additive-free, bland emollient or moisturizer twice daily for at least 7 days before the Baseline visit. * Documented history (within 6 months of the Baseline visit) of inadequate response or intolerance to topical corticosteroids (TCS) and/or topical calcineurin inhibitors (TCI) or a systemic immunomodulating therapy, or medical inadvisability of available systemic therapy (e.g., because of important side effects or safety risks). Exclusion Criteria: * Participants that have current and/or history of other active skin diseases (e.g., psoriasis or Netherton syndrome or lupus erythematosus) or skin infections (bacterial, fungal, or viral) requiring systemic treatment within 4 weeks of the Baseline visit or that would interfere with the appropriate assessment of AD lesions. * Participants that have used topical treatments for AD (except for topical emollient or moisturizer treatments) including but not limited to TCS, TCI, or topical PDE-4 inhibitors, within 7 days of the Baseline visit or any the following prohibited AD treatments within the specified timeframes below prior to the Baseline visit: * Systemic therapy for AD, including but not limited to corticosteroids and cyclosporine, within 4 weeks; * Targeted biologic treatments within 5 half-lives (if known) or within 12 weeks, whichever is longer; * Phototherapy treatment, laser therapy, tanning booth use, or extended sun exposure that could affect disease severity or interfere with disease assessments within 4 weeks.
