Summary
Brief 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 improves 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.
