Summary

This is an up to 22-week clinical study in adult participants with moderate to severe atopic dermatitis (AD).

The purpose of the study is to test a new tablet (LEO 152020) to see if it works to treat AD and what the side effects are when compared with a placebo tablet with no medical ingredient.

During the study, there will be a 16-week treatment period during which the participants will be asked to take the tablets. The participants will regularly visit the clinic for tests and the study doctor will evaluate their AD. The participants will also be asked to answer questions about their AD symptoms, itch, sleep, and quality of life.
