About this study
Official title: Ocular Pharmacokinetics After a Single Drop Instillation, in Each Eye of One of Three Different Concentrations of T1225 (0.5% - 1% - 1.5% Dihydrate) in 91 Healthy Volunteers
To evaluate azithromycin tear concentrations after instillation of one drop of one of the three T1225 concentrations (0.5%, 1% and 1.5%) and to evaluate the ocular safety.
Read the detailed description
The aim of the present study was to compare azithromycin tear ocular concentrations after a single instillation of three different T1225 concentrations in order to determine early azithromycin tear concentration and to assess the T1225 concentration, which allowed having the higher azithromycin tear concentration, 24 hours after a single instillation.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Azithromycin in people with Eye Infections, Bacterial, run by Laboratoires Thea.
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 8 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 26 Jul 2006. Status can change between updates, so confirm with the study contact before making plans.
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?
Area Under the Curve from 0 to 24 hours (AUC0-24h). The study lists 4 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 26 Jul 2006.
