Eczema cream safety during pregnancy under scrutiny: new study compares ruxolitinib to steroids
NCT ID NCT06627335
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study will analyze health records of over 5,600 pregnant women with atopic dermatitis (eczema) to compare infant outcomes between those who used ruxolitinib cream (Opzelura) and those who used topical corticosteroid creams. Researchers will look at rates of major birth defects, small-for-gestational-age births, and other pregnancy outcomes. The goal is to better understand the safety of these treatments during pregnancy.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ruxolitinib cream (Opzelura) and topical corticosteroids
- What this could lead to
- If successful, this study could provide important safety information about using ruxolitinib cream during pregnancy for women with atopic dermatitis.
- What could go wrong
- This is an observational study using existing claims data, not a controlled trial. It can show associations but not prove cause and effect. Results may be limited by data accuracy and unmeasured factors.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Women aged 14 years or older at pregnancy outcome. * Pregnancy following FDA approval of ruxolitinib cream for AD on 21 SEP 2021. * At least 1 pharmacy-dispensing claim for ruxolitinib cream (ruxolitinib-exposed cohort) or a TCS (TCS-exposed cohort). * A diagnosis of AD prior to or on the day of the first pharmacy claim for ruxolitinib cream (ruxolitinib-exposed cohort) or a TCS (TCS-exposed cohort) from 6 months before the estimated date of conception. * Continuous enrollment in the database from 6 months before the estimated date of conception through the end of pregnancy. * For infant outcomes only, linkage of mother and infant data will be required (ie, pregnancies that cannot be linked to an infant will be excluded for infant outcomes but not for pregnancy outcomes). Infants will be followed for as long as they are continuously enrolled in the database up to 1 year after birth (ie, variable follow-up for each infant). A 1-year fixed period of continuous enrollment after birth will not be imposed so as not to introduce survival bias. Exclusion Criteria: • One or more pharmacy claims for oral ruxolitinib or other JAK inhibitors in the exposure window for a given outcome.
