About this study
Official title: Pharmacokinetic Study of the Amoxicillin / Clavulanic Acid Association to Optimize Dosage Among Obese Adults (PHACO)
Description of the pharmacokinetic parameters of the amoxicillin / clavulanic acid to healthy voluntary obese after oral and intra venous administration Determination of the pharmacokinetic parameters of amoxicillin / clavulanic acid obtained from plasmatic concentrations of intravenous injection (IV) and oral administrations. The criterion of evaluation allowing to answer our main objective corresponds to the parameters estimated by the pharmacokinetic model of the concentrations obtained from the data IV and by the pharmacokinetic model of the concentrations obtained from the oral data. The following pharmacokinetic parameters will be considered at every obese volunteer's for both molecules (amoxicillin and clavulanic acid) from the concentrations by pharmacokinetic analysis of population.
The main evaluation criteria are PK parameters of amoxicillin / clavulanic:
- Cl, systematic plasmatic clearance
- Vd, volume of distribution
- ASC 0-oo, area under the curve time - concentration
- T1/2, half-life time
- F, bioavailability after oral administration
- Ka, constant of speed of absorption

Main objective Description of the pharmacokinetic parameters of the amoxicillin / clavulanic acid to healthy voluntary obese after oral and intra venous administration
Secondary objectives
- Define dosage plans optimized with the antibiotic treatment to the obese subject
- Ensure an adequacy of the treatment with the related infection
- Formulate recommendations of dosage adaptations for a better individualization of treatments, by estimating several plans of doses by simulation to reach various PK/PD goals according to different theoretical MIC
Methodology
The pharmacokinetic analysis will be realized by approach of population allowing the estimation of the average parameters of amoxicillin and clavulanic acid as well as the interpersonal variability after an administration IV and an oral administration. Parameters's population and their variability will be estimated with the SAEM algorithm implemented in the software Monolix ( www.lixoft.eu ).
For the main objective, PK parameters PK of amoxicillin and clavulanic acid will be determined to day 1 and day 2. They will be described by means of indicators of position (average and median) and of dispersal (standard deviations, quartiles).
For secondary objectives, the profiles concentration/time of 1000 obese subjects will be determined by Monte Carlo method from PK parameters estimated at the balance by the model. For every feigned profile, the time during which the plasmatic concentration of amoxicillin and clavulanic acid is superior to a panel of theoretical MIC will be calculated by means of curves concentration - time determined for each of the subjects.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing amoxicillin and clavulanic acid in people with Obesity, run by Institut de Médecine et d'Epidémiologie Appliquée - Fondation Internationale Léon M'Ba at 1 site in France.
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 6 inclusion and 25 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 12 Jan 2018. 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 France. 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 combined 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.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Systematic plasmatic clearance (Cl) (time frame: 1 day). 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 12 Jan 2018; AzTrials last refreshed its copy on 8 Nov 2026.
