An Evaluation of LEO 138559 in Adults With Moderate to Severe Atopic Dermatitis.
Study Details
Study Description
Brief Summary
This is a clinical study in adult participants with moderate to severe atopic dermatitis (AD).
The purpose of the study is to test a new medicine (LEO 138559) given by injection to see if it works to treat AD and what the side effects are when compared with a placebo injection with no medical ingredient.
The study will last up to 36 weeks for each participant. The study will include a treatment period of 16 weeks, during which the participants will receive the injections, followed by a period of 16 weeks without treatment with the main purpose of continuing safety evaluations. 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 and quality of life.

Placebo Comparator: Placebo Participants will receive injections of placebo from Week 0 (baseline) to Week 16 (end of treatment). |
Drug: LEO 138559 placebo
LEO 138559 placebo is given by injection just under the skin. LEO 138559 placebo contains the same excipients in the same concentration as LEO 138559, except the medical ingredient LEO 138559.

Outcome Measures
Primary Outcome Measures
- Change in EASI score from baseline to Week 16 [Week 0 to Week 16]
The Eczema Area and Severity Index (EASI) is a validated measure used in clinical trials to evaluate the extent and severity of atopic dermatitis. EASI is a composite score ranging from 0 to 72 with higher scores indicating a more extensive and/or severe condition.
Secondary Outcome Measures
- Number of treatment-emergent adverse events from baseline to Week 16 per subject [Week 0 to Week 16]
Eligibility Criteria
Criteria

-
Eczema Area and Severity Index (EASI) score ≥12 at screening and ≥16 at baseline.
-
Validated Investigator Global Assessment Scale for Atopic Dermatitis (vIGA-AD) score ≥3 at screening and baseline.
