Condition(s) targeted: Healthy Volunteers

Intervention: Sotalol 80 mg (Drug)

Phase: Phase 1

Status: Completed

Sponsored by: Assistance Publique - H˘pitaux de Paris

Official(s) and/or principal investigator(s):
Beny Charbit, MD, Principal Investigator, Affiliation: H├┤pital Saint Antoine, Assistance Publique - Hopitaux de Paris


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

Clinical Details

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

Study design: Endpoint Classification: Pharmacodynamics Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: The elongation of the corrected interval QT duration 3 hours after the unique oral taking of an 80 mg dose of Sotalol.

Secondary outcome:

Constitute a biological base and a phenotypic base of resources which will allow to define answer phenotypes to the implemented dynamic tests

Look for associations between these phenotypes of electrocardiographically answer and mutations or polymorphisms.

Detailed description: Study of 1000 apparently healthy subjects which will receive an unique dose of Sotalol and will have an effort test on ergonomic bicycle, an auditive stimulation and a taking of DNA.
