American-Australian-African Trial With Dronedarone in Patients With Atrial Fibrillation or Atrial Flutter for the Maintenance of Sinus Rhythm (ADONIS)
American-Australian-African Trial With Dronedarone in Atrial Fibrillation or Flutter Patients for the Maintenance of Sinus Rhythm (ADONIS)
To assess the efficacy of dronedarone versus placebo for the maintenance of normal sinus rhythm after electrical, pharmacological or spontaneous conversion of atrial fibrillation/atrial flutter (AF/AFL).
To assess the efficacy of dronedarone versus placebo on ventricular rate control in case of AF/AFL recurrence.
To assess the efficacy of dronedarone versus placebo on AF/AFL-related symptoms.

Detailed Description
This is a double-blind, parallel arm, placebo-controlled, multicentre, multinational, phase III study.
To be eligible, patients must be in normal sinus rhythm at randomisation and must have an ECG-documented history of recent AF/AFL reverted to normal sinus rhythm by electrical, pharmacological or spontaneous conversion.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
---|
The primary endpoint of the study is the time from randomisation to first documented AF/AFL recurrence
|
Secondary Outcome Measures
Outcome Measure |
---|
- AF/AFL related symptoms collected at the time of ECG/TTEM recording,
|
- mean ventricular rate during AF/AFL at first recorded AF/AFL recurrence (12-lead ECG or TTEM)
|
- time from presumed study drug near steady state defined as D5 midnight to first documented AF/AFL recurrence as indicated by ECG/TTEM recording.
