Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Participants Investigators Outcome Assessors
The outcome assessor is considered to be the person/people who will assess the outcome of the data/study and will in this study therefore be the sponsor.

To ensure masking across the interventions, each dose of treatment in the LEO 152020 tablet - Dose regimen 2 and LEO 152020 tablet - Dose regimen 3 arms will consist of a combination of LEO 152020 and LEO 152020 placebo tablets. In these arms, placebo will be used as a masking aid and is therefore considered neither a control nor an intervention.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.
