Primary Outcome Measures:
- To demonstrate the effectiveness of RSD1235 in the conversion of atrial fibrillation to sinus rhythm. [ Time Frame: The proportion of patients with atrial fibrillation (AF) of 3 hours to 7 days duration who have treatment-induced conversion of AF to sinus rhythm for a minimum duration of one minute in the first 90 minutes after the first exposure to study treatment. ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- To assess the safety of RSD1235 in this patient population. [ Time Frame: The proportion of patients with AF of 3 hours to 45 days duration who have treatment-induced conversion of AF to sinus rhythm for a minimum duration of one minute in the first 90 minutes after the first exposure to study treatment. ] [ Designated as safety issue: Yes ]
There are approximately 2 million reported prevalent cases of atrial fibrillation (AF) and atrial flutter in the United States (Heart Disease & Stroke Statistics - 2003 Update, AHA). These arrhythmias may be occasional or sustained. While not directly fatal, these arrhythmias cause discomfort and can lead to stroke or congestive heart failure.
This Phase III trial is Cardiome's first pivotal study with RSD1235. The study seeks to confirm the findings of the Phase II proof-of-concept through demonstration of RSD1235's abilities to convert AF to sinus rhythm. The patient population will include recent onset AF (AF duration of 3 hours to 7 days) and patients with longer AF duration.
This is a double-blind, placebo-controlled, randomized study in patients with AF; stratification will be based on duration of AF. Treatment will be considered successful if there is a treatment-induced conversion of atrial arrhythmia to sinus rhythm for a minimum of 1-minute by Hour 1.5 (Time 0 = start of first infusion). All patients will be evaluated for safety.
