Study to Compare Maternal, Fetal, and Infant Outcomes of Women With Mild to Moderate Atopic Dermatitis Exposed to Ruxolitinib Cream During Pregnancy With an Unexposed Control Population (OPERA-1)

December 4, 2025 updated by: Incyte Corporation

A US-Prospective, Registry-Based, Observational, Exposure Cohort Study to Compare Maternal, Fetal, and Infant Outcomes of Women With Mild to Moderate Atopic Dermatitis Exposed to Ruxolitinib Cream During Pregnancy With an Unexposed Control Population

This observational (enrollment into the registry while the pregnancy is ongoing) study is being conducted to compare the frequency of major congenital malformation (MCM)s among infants of women exposed to ruxolitinib cream during pregnancy with infants of women not exposed to ruxolitinib cream during pregnancy.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is an exposure cohort study of women within the US with AD who were exposed to ruxolitinib cream at any time during their pregnancy period, defined as up to 24 days prior to the estimated date of conception (DOC) through the end of pregnancy, compared with women in the US with Atopic Dermatitis (AD) not exposed to ruxolitinib cream during pregnancy. The DOC is estimated to occur 14 days after the last menstrual period (LMP). Eligible pregnant women may self-enroll or voluntarily be enrolled by their health care provider (HCP) by calling Syneos Health. Enrollment should occur as early in pregnancy as possible.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Exposure cohort study of women within the US with atopic dermatitis (AD) who were exposed to ruxolitinib cream at any time during their pregnancy period.

Description

Inclusion Criteria:

  • Women, aged 15 to 50 years, with confirmed diagnosis of mild to moderate AD.
  • Ability to comprehend and willingness to give informed consent for the study; a legal minor needs parental or legally authorized representative's consent.
  • Prospective enrollment (ie, enrollment into the registry while the pregnancy is ongoing) or retrospective enrollment (ie, enrollment into the registry within 12 months of pregnancy outcome).

  • Information available to confirm eligibility for either the exposed to ruxolitinib cream cohort or the not exposed to ruxolitinib cream cohort.

    • Ruxolitinib cream cohort: consisting of pregnancies in women with AD and exposure to at least 1 application of ruxolitinib cream during the pregnancy period.
    • Nonexposed cohort: consisting of pregnancies in women with AD but not exposed to ruxolitinib cream during the pregnancy period
  • Reporter (eg, participant, maternal HCP) contact information available to allow for follow-up.
  • Permission to contact the participant's and her infant's HCPs.

Exclusion Criteria:

  • If no longer pregnant and pregnancy outcome occurred more than 12 months prior to enrollment.
  • Current treatment or treatment within 30 days or 5 half-lives (whichever is longer) before enrollment with another investigational medication or current enrollment in another investigational drug study.
  • Any pregnancy that is exposed to any other JAK inhibitor from 5 half-lives for the specific JAK inhibitor used from LMP through the end of the first trimester for MCMs or end of pregnancy for other outcomes.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of major congenital malformation (MCM)s
