About this study
Official title: A Phase 1, 3-part, Single (Open-label) and Multiple (Double-blind, Placebo-controlled) Oral Dose Trial to Evaluate the Safety, Tolerability, and Pharmacokinetics of LEO 32731 Formulations in Healthy Subjects
This is a phase 1 trial to evaluate the safety, tolerability, and pharmacokinetics of 4 different oral formulations of LEO 32731 in healthy subjects. The trial will be conducted in 3 parts at a single site. Each eligible subject will be enrolled into 1 group only and will participate in 3 treatment periods.
Read the detailed description
Part 1 will evaluate the pharmacokinetics of single doses of 4 test formulations of LEO 32731 compared with a reference formulation. Part 2 will evaluate the effect of food on the pharmacokinetics of selected test formulations of LEO 32731. Part 3 will evaluate the tolerability and safety of selected test formulations of LEO 32731 after multiple dosing.
Based on data from Part 1, up to 3 formulations will be taken forward to Part 2. If none of the formulations are considered appropriate to take forward to Part 2, the trial will stop after Part 1. Similarly, based on data from Part 2, up to 2 formulations will be taken forward to Part 3. If none of the formulations are considered appropriate to take forward to Part 3, the trial will stop after Part 2.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This is a phase 1 trial to evaluate the safety, tolerability, and pharmacokinetics of 4 different oral formulations of LEO 32731 in healthy subjects. The trial will be conducted in 3 parts at a single site. Each eligible subject will be enrolled into 1 group only and will participate in 3 treatment periods.
Detailed description
Part 1 will evaluate the pharmacokinetics of single doses of 4 test formulations of LEO 32731 compared with a reference formulation. Part 2 will evaluate the effect of food on the pharmacokinetics of selected test formulations of LEO 32731. Part 3 will evaluate the tolerability and safety of selected test formulations of LEO 32731 after multiple dosing.
Based on data from Part 1, up to 3 formulations will be taken forward to Part 2. If none of the formulations are considered appropriate to take forward to Part 2, the trial will stop after Part 1. Similarly, based on data from Part 2, up to 2 formulations will be taken forward to Part 3. If none of the formulations are considered appropriate to take forward to Part 3, the trial will stop after Part 2.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing LEO 32731 modified release tablet, LEO 32731 blend, hard capsule and LEO 32731 API, hard capsule in people with Healthy, run by LEO Pharma at 1 site 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 5 inclusion and 6 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 1 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site 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. Some participants in this study may receive a placebo. 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?
Part 1. AUC0-∞ (time frame: Calculated using concentration data collected from predose to 48 hours postdose for each treatment period in Part 1). The study lists 9 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 1 Jul 2019.
