Atopic Dermatitis (AD) is a common skin condition that makes skin itchy and red. This study looks at people with AD who start or change their medicine. It doesn’t involve any new medicines or treatments, just observing what happens in real life. The goal is to understand the needs of people with AD and see how different medicines work for them. People in the study will be checked for things like age, skin color, and what makes their AD worse.

The study will happen in 10 countries and last for 5 years. To join, you need to be at least 12 years old, have a confirmed diagnosis of AD, and be starting a new medicine for AD, like biologics or other oral medicines. You also need to agree to stay in the study for the whole time. You cannot join if you’re in another study that changes your treatment or if you don’t understand the study well.

• Study lasts 5 years with visits over time.
• No new treatments, just tracking current ones.
• Participants should be willing to stay in the study long-term.
