How well a skin medicine works over two years

This is a real-world study that follows patients already taking dupilumab for atopic dermatitis (a chronic skin condition causing itching, redness, and inflammation). Rather than testing whether the medication is safe or effective in a controlled setting, researchers want to understand how well this treatment works in everyday life—what happens to symptoms, quality of life, and skin control over two years in regular medical practice.

While this medication has been approved for atopic dermatitis, doctors need to understand how it performs outside research clinics—whether it works the same way for different age groups, how long patients stay on it, and what long-term safety looks like when real patients take it with all their other health conditions and treatments.
