Official title: Randomised, Double-blind, Placebo-controlled, Single and Multiple Ascending Dose Trial to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of LEO 138559 in Healthy Subjects and Subjects With Moderate to Severe Atopic Dermatitis

The primary objective of this trial is to investigate the safety and tolerability of LEO 138559 in healthy subjects and subjects with moderate to severe atopic dermatitis.

The secondary objective of this trial is to study the pharmacokinetics and pharmacodynamics following administration of LEO 138559 to healthy subjects and subjects with moderate to severe atopic dermatitis.

Healthy subjects will be exposed to 7 different dose regimens of LEO 138559 (one dose regimen per subject).

Subjects with moderate to severe atopic dermatitis will be exposed to 2 different dose regimens of LEO 138559 (one dose regimen per subject).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing LEO 138559 in people with Atopic Dermatitis, run by LEO Pharma at 3 sites in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety of LEO 138559 - numbers of subjects with adverse events (time frame: Day 1 to Day 120). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Feb 2025.
