First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This long-term study follows 1,000 people with eczema and related allergies, plus healthy volunteers, to see what factors help the disease go into remission. Researchers will collect medical and lifestyle data to find patterns and possible biomarkers. The goal is to better understand why some people improve and others don't, paving the way for more personalized care.
