Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To assess the efficacy of dronedarone in preventing cardiovascular hospitalization or death from any cause in a population of high-risk patients with atrial fibrillation/atrial flutter (AF/AFL).

To assess that dronedarone is well tolerated in this population.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a prospective, multinational, double-blind, randomized, multi-center, placebo-controlled, parallel-group trial evaluating the effects of dronedarone versus placebo (ratio 1:1) over a minimum treatment duration of 12 months and a mean follow-up duration of 1.75 years (in AF/AFL patients). Patients can be included in the study while in atrial fibrillation/flutter or in sinus rhythm if conversion has occurred either spontaneously or following a procedure such as electrical cardioversion (or overdrive pacing) or administration of an antiarrhythmic drug.After randomization all patients will be followed until the common study end date; the last patient included in the study will be followed for 1 year. Visits will be at baseline, after 7 days, after 14 days, after one month, after three months and then every three months until end of the study. At each visit patients will be asked for the occurrence of hospitalizations or other events since the last visit. The study will be monitored by an independent Data Monitoring Committee (DMC) for safety, tolerability and efficacy.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* 1\. Patients aged 75 years or older (70 years before protocol amendment 1), or patients aged at least 70 years (any age before protocol amendment 1) with one or more of the following risk factors at baseline:

* Hypertension (taking antihypertensive drugs of at least two different classes)
* Diabetes
* Prior cerebrovascular accident (stroke or transient ischemic attack) or systemic embolism
* Left atrium diameter greater than or equal to 50 mm by echocardiography
* Left ventricular ejection fraction less than 0.40 by 2D-echocardiography (two-dimensional echocardiography)
* 2\. Availability of one electrocardiogram (ECG) within the last 6 months, showing that the patient was or is in AF/AFL
* 3\. Availability of one ECG within the last 6 months, showing that the patient was or is in sinus rhythm

Exclusion Criteria

General criteria:

* 1\. Refusal or inability to give informed consent to participate in the study
* 2\. Any non cardiovascular illness or disorder that could preclude participation or severely limit survival including cancer with metastasis and organ transplantation requiring immune suppression
* 3\. Pregnant women (pregnancy test must be negative) or women of childbearing potential not on adequate birth control: only women with a highly effective method of contraception \[oral contraception or intra-uterine device (IUD)\] or sterile can be randomized.
* 4\. Breastfeeding women
* 5\. Previous (2 preceding months) or current participation in another clinical trial with an investigational drug (under development) or with an investigational device
* 6\. Previous participation in this trial

Criteria Related to a cardiac condition:

* 7\. Patients in permanent atrial fibrillation
* 8\. Patients in unstable hemodynamic condition such as acute pulmonary edema within 12 hours prior to start of study medication; cardiogenic shock; treatment with intra-venous pressor agents; patients on respirator; congestive heart failure of stage NYHA IV (New York Heart Association classification) within the last 4 weeks; uncorrected, hemodynamically significant primary obstructive valvular disease; hemodynamically significant obstructive cardiomyopathy; a cardiac operation or revascularization procedure within 4 weeks preceding randomization
* 9\. Planned major non-cardiac or cardiac surgery or procedures including surgery for valvular heart disease, coronary artery bypass graft (CABG) , percutaneous coronary intervention (PCI) , or on urgent cardiac transplantation list
* 10\. Acute myocarditis or constrictive pericarditis
* 11\. Bradycardia \< 50 bpm and/or PR-interval \> 0.28 sec on the last 12-lead ECG
* 12\. Significant sinus node disease (documented pause of 3 seconds or more) or 2nd or 3rd degree atrioventricular block (AV-block) unless treated with a pacemaker

Criteria Related to Concomitant Medications:

* 13\. Need of a concomitant medication that is prohibited in this trial, including the requirement for Vaughan Williams Class I and III anti-arrhythmic drugs, that would preclude the use of study drug during the planned study period

Criteria Related to Laboratory Abnormalities:

* 14\. Plasma potassium \< 3.5 mmol/l (as anti-arrhythmic drugs can be arrhythmogenic in patients with hypokalemia, this must be corrected prior to randomization)
* 15\. A calculated Glomerular Filtration Rate (GFR) at baseline \<10 ml/min using the Cockroft Gault formula
