Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
Primary Objective:

* Demonstrate the efficacy of Dronedarone in preventing major cardiovascular events (stroke, systemic arterial embolism, myocardial infarction or cardiovascular death) or unplanned cardiovascular hospitalization or death from any cause in patients with permanent Atrial Fibrillation \[AF\] and additional risk factors

Secondary Objective:

* Demonstrate the efficacy of Dronedarone in preventing cardiovascular death

This was an event-driven study where a common study end date \[CSED\] was to be determined by Steering Committee based on the number of events (stroke, systemic arterial embolism, myocardial infarction or cardiovascular death).
