About this study
Official title: An Open-Label, Single Oral Dose Phase I Study to Determine the Excretion Balance of Radiocarbon (i.e., the Sum of 14C-Labelled GFT505 and Its 14C-Metabolites) and to Investigate the Metabolic Profile and Pharmacokinetics of GFT505
Human mass-balance studies with radiolabelled study drug are needed to evaluate the amount of drug that is recovered over time via different elimination routes of the body, i.e., whole blood, blood cells, plasma, urine, feces, and expired air. The ideal case is to be able to demonstrate a (near) complete recovery (≥95 %) of the administered dose.
A good understanding of the metabolic pathway of the study drug is equally important. Mass-balance data, together with metabolic profiles in excreta, are used to characterize the biotransformation pathways of a drug and to help evaluate its drug-drug interaction potential.
To this purpose, in this study, blood, urine, and feces are collected to investigate the metabolic profile of GFT505, and plasma and urine are collected to investigate the non-radioactive pharmacokinetics of GFT505 and its principle metabolite GFT1007. Other metabolites will be investigated in plasma and urine according to the radioactivity results. Non-radioactive pharmacokinetics of GFT505 and metabolites in feces will be investigated according to the radioactivity results.
Read the detailed description
This is a Phase I open-label, single oral dose and single center study of 14C-labelled GFT505 and its metabolites in healthy subjects.
After an overnight fast, subjects will be administered one dose of 14C-labelled GFT505 containing an equivalent of 120 mg of the compound with 240 mL of non-carbonated water. The total amount of administered radiocarbon will be 1.63-1.81 megaBecquerel (MBq) (44.1-48.8 μCi).
Blood, urine, and feces will be collected at scheduled time intervals from before administration of the radiolabelled study drug throughout confinement at the clinical center and thereafter, if needed. Several samples of expired carbon dioxide will be obtained up to 48 h after the administration of radiolabelled study drug.
Radiocarbon will be assayed in all available samples (whole blood, plasma, urine, feces, and expired air) by liquid scintillation spectrometry. The metabolic profile of GFT505 will be assayed in plasma, urine, and feces. Non-radioactive pharmacokinetics of GFT505 and its principle metabolite GFT1007 will be assayed in plasma and urine. Other metabolites will be investigated in plasma and urine according to the radioactivity results. Non-radioactive pharmacokinetics of GFT505 and metabolites in feces will be investigated according to the radioactivity results.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing 14C-labelled GFT505 120 mg in people with Healthy, run by Genfit at 1 site in Belgium.
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 4 inclusion and 13 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 29 May 2015. 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 Belgium. 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?
Excretion balance of radiocarbon in whole blood, blood cells, plasma, urine, feces, and expired air after a single oral dose of 14C-labelled GFT505. (time frame: 0-19 days). 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 29 May 2015; AzTrials last refreshed its copy on 8 Nov 2026.
