Primary Outcome Measures:
  • Time from randomization to first occurrence among stroke, systemic arterial embolism, myocardial infarction or cardiovascular death [ Time Frame: Follow-up between 3 months (last patient) and 3 years (first patient) ] [ Designated as safety issue: No ]
    The follow-up is until the common study end date that is a fixed date that will be set by the Steering Committee during the study.

  • Time from randomization to first occurrence of unscheduled cardiovascular hospitalization or death from any cause [ Time Frame: Follow-up between 3 months (last patient) and 3 years (first patient) ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Time from randomization to cardiovascular death [ Time Frame: Follow-up between 3 months (last patient) and 3 years (first patient) ] [ Designated as safety issue: No ]

Enrollment: 3236
Study Start Date: July 2010
Study Completion Date: September 2011
Primary Completion Date: July 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Dronedarone
SR33589, 400 mg, one tablet twice a day with the morning and evening meals
Drug: Dronedarone (SR33589)

Pharmaceutical form:tablet

Route of administration: oral

Placebo Comparator: placebo
placebo, one tablet twice a day with the morning and evening meals
Drug: placebo

Pharmaceutical form:tablet

Route of administration: oral


Detailed Description:

All patients are followed until a Common Study End Date that will be anticipated based on the projected blind number of events (stroke, systemic arterial embolism, myocardial infarction or cardiovascular death). The follow-up duration per patient should range between 3 months (last patient) and 3 years (first patient).

  Eligibility

Ages Eligible for Study:   65 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion criteria:

  • Permanent AF defined by the presence of all of the following criteria:

    • Availability of one 12-lead ECG not more than 14 days prior to randomization showing that the patient is in AF or atrial flutter
    • Availability of documentation (including either rhythm strips or medical report of the rhythm) showing that the patient was in AF or atrial flutter at least 6 months prior to randomization
    • No evidence of sinus rhythm in the period between these two documentations of AF
    • Patient and physician decision to allow AF to continue without further efforts to restore sinus rhythm
  • At least one of the following risk criteria:

    • Coronary artery disease
    • Prior stroke or Transient Ischemic Attack (TIA)
    • Symptomatic heart failure
    • Left ventricular ejection fraction ≦ 0.40
    • Peripheral arterial occlusive disease
    • Aged 75 years or older with both hypertension and diabetes mellitus

Exclusion criteria:

  • Paroxysmal AF
  • Persistent AF without a decision to allow AF to continue without further efforts to restore sinus rhythm
  • Heart failure of New-York Heart Association (NYHA) class IV or recent unstable NYHA class III
