Ethnic Differences in Mechanisms of Action of Dupilumab
United States30 participantsStarted 2023-01-25
Plain-language summary
Previous research has shown that Asian and African Americans are more likely to develop atopic dermatitis (AD) than their Caucasian counterparts. However, limited information is known about AD in Asian and African American populations because most molecular studies have focused on Caucasians with AD.
This trial will determine differences in inflammatory responses to dupilumab between Caucasian, Asian, and African American patients with AD.
The central hypothesis of this study is that ethnic differences in both immune and stromal cells contribute to variability in AD presentation and response to anti-interleukin-4 receptor (IL-4R) inhibition with dupilumab.

Exclusion criteria
. Had an exacerbation of asthma requiring hospitalization in the preceding 12 months.
. Reporting asthma that has not been well-controlled (ie, symptoms occurring on \>2 days per week, nighttime awakenings 2 or more times per week, or some interference with normal activities) during the preceding 3 months
. Asthma Control Test (ACT) \< 19 (only for subjects with a history of asthma).
. Subjects with a current medical history of chronic obstructive pulmonary disease and/or chronic bronchitis.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Difference in inflammatory response to dupilumab between Caucasian, Asian and African American patients with atopic dermatitis as measured by change in expression of interleukin4 (IL4) from week 0 to 2.
