Eligibility
Key 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
Minimum age
70 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key 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
