About this study
Official title: Identification of the Genetic Sources of Variability of the Adaptation of the Ventricular Repolarisation at a Pharmacological and Physiological Stimulus in an Apparently Normal Population
The main objective is to research for genetic factors involved in the extreme modifications of the QT interval of the electrocardiogram in answer to a pharmacological stimulation (sotalol) and physiological stimulation in the apparently normal general population.
The phenotypic characterization, based on the ventricular repolarisation dynamics will be used aiming at term of the predictive genetic factors of the acquired long QT syndrome
Read the detailed description

- Conditions
- Healthy Volunteers
- Being tested
- Sotalol 80 mg
- Keywords
- Long QT syndrome, Cardiac repolarisation, Genome-wide association, Electrophysiology, Drugs/adverse effects

| Study group | Role | What they receive |
|---|---|---|
| 1 | Experimental | Healthy subjects Receives: Drug: Sotalol 80 mg |
What is being measured
The primary outcome is the main question the study is designed to answer.
The elongation of the corrected interval QT duration 3 hours after the unique oral taking of an 80 mg dose of Sotalol.
Measured: 3 hours after the taking of Sotalol
Secondary outcomes (2)
Constitute a biological base and a phenotypic base of resources which will allow to define answer phenotypes to the implemented dynamic tests
Measured: At the inclusion visit
Look for associations between these phenotypes of electrocardiographically answer and mutations or polymorphisms.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Sotalol 80 mg in people with Healthy Volunteers, run by Assistance Publique - Hôpitaux de Paris 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 5 inclusion and 10 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 2012. 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 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?
The elongation of the corrected interval QT duration 3 hours after the unique oral taking of an 80 mg dose of Sotalol. (time frame: 3 hours after the taking of Sotalol). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00773201, which also lists 1 linked publication.
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 2012; AzTrials last refreshed its copy on 8 Nov 2026.
