About this study
Official title: An Open Label, Single-Dose, Single-Period Study Designed to Assess the Mass Balance Recovery, Metabolite Profile and Metabolite Identification of [14C]-Acebilustat (CTX-4430) in Healthy Male Subjects
This is a single-centre, open-label, non-randomised, single oral dose study in healthy male subjects. It is planned to enroll and dose 6 subjects. Subjects will be admitted to the clinical unit on the evening of Day 1 prior to investigational medicinal product (IMP) administration. Subjects will be dosed on the morning of Day 1 and it is planned that they will remain resident in the clinic until up to 168 hour after dosing (up to Day 8). It is planned that subjects will be released as a group when all subjects have achieved a mass balance cumulative recovery of >90% or if <1% of the dose administered has been collected in urine and faeces within 2 separate, consecutive 24 hour periods.
- Conditions
- Heathy Volunteers
- Being tested
- [14C]-acebilustat solution
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
[14C]-acebilustat solutionDrug
Acebilustat is a novel synthetic small molecule leukotriene A4 hydrolase (LTA4H) inhibitor.
| Study group | Role | What they receive |
|---|---|---|
| 100 mg [14C]-acebilustat | Other | a single oral dose of 100 mg [14C]-acebilustat Receives: Drug: [14C]-acebilustat solution |
What is being measured
The primary outcome is the main question the study is designed to answer.
Mass balance recovery of total radioactivity in all excreta: amount excreted (Ae) and Ae as a percentage of the administered dose (%Ae), cumulative recovery (CumAe), and cumulative recovery expressed as a percentage of the administered dose (Cum%Ae)
Measured: Day 10

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing [14C]-acebilustat solution in people with Heathy Volunteers, run by Celtaxsys, Inc. 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 1 inclusion and 3 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 30 May 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. 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?
Mass balance recovery of total radioactivity in all excreta: amount excreted (Ae) and Ae as a percentage of the administered dose (%Ae), cumulative recovery (CumAe), and cumulative recovery expressed as a percentage of the administered dose (Cum%Ae) (time frame: Day 10). 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 30 May 2019.
