Dronedarone Pattern of Use in Patients Scheduled for Elective Cardioversion (ELECTRA)

Phase 4
Terminated
Conditions
Atrial Fibrillation
Interventions
Drug: Placebo (for dronedarone)
Registration Number
NCT01026090
Lead Sponsor
Sanofi
Brief Summary

Primary Objective:

To determine whether daily administration of dronedarone started 5-7 days before cardioversion is superior to dronedarone started only after cardioversion with respect to the absence of symptomatic, ECG confirmed, atrial fibrillation (AF) recurrence over 6 months in adult patients with persistent AF, for whom cardioversion is clinically indicated and planned to reduce symptoms and antiarrhythmic treatment is clinically indicated to reduce the risk of cardiovascular hospitalization due to AF.

Secondary Objectives:

Main Secondary :

* To assess the number of symptomatic AF recurrences/patient/6 months with and without ECG confirmation;

* To assess characteristics of symptomatic AF recurrence in the two treatment arms (frequency, duration of episodes, type, number, and severity of AF symptoms per patient);

* To compare the rates of early recurrences of AF between the two treatment strategies;

Other secondary:

* To assess whether there is a difference in proportion of patients with symptomatic AF recurrences (with and without ECG confirmation) between the two treatment strategies;

* To assess whether there is a difference in number of electrical cardioversions per patient between the two treatment strategies;

* To assess the impact of the two strategies on number of shocks, cumulative amount of energy delivered, shock failure, and immediate success of cardioversion;

* To assess whether there is a difference in rate of cardiovascular (CV) hospitalizations and length of hospital stay between the two treatment strategies;

* To assess whether there is a difference in quality of life between the two treatment strategies.

Detailed Description

The study period of approximatively 6 months consisted in:

* Double-blind treatment period (placebo or dronedarone) for 5-7 days prior to cardioversion;

* Electrical cardioversion;

* Open-label treatment period with dronedarone for 6 months after cardioversion.
