Effect of Addition of Dronedarone to Standard Rate Control Therapy on Ventricular Rate During Persistent Atrial Fibrillation (AFRODITE) - Full Text View

Sponsor:	Sanofi-Aventis
Information provided by (Responsible Party):	Sanofi-Aventis
ClinicalTrials.gov Identifier:	NCT01047566

Purpose

The primary objective of this study is to:

Assess whether the addition of dronedarone to existing conventional rate control therapy leads to a reduced ventricular rate after 1 week in patients with a high Heart Rate (HR) at rest during Atrial Fibrillation (AF) in comparison to an increase of conventional therapy.

The secondary objectives of this study are to compare both study arms with regard to:

Ventricular rate after 3 months
Number of registered AF episodes
Number of symptomatic AF episodes
Severity of AF and AF-like symptoms
Rate of premature study discontinuation
Number of symptomatic episodes of bradycardia
Incidence of low heart rate (<60 bpm)

Condition	Intervention	Phase

Study Design:	Allocation: Randomized Endpoint Classification: Efficacy Study Intervention Model: Parallel Assignment Masking: Open Label Primary Purpose: Treatment
Official Title:	The Effect of the Addition of Dronedarone to, Versus Increase of, Existing Conventional Rate Control Medication on Ventricular Rate During Persistent Atrial Fibrillation

Primary Outcome Measures:

Ventricular rate [ Time Frame: One week ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Ventricular rate [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
Patients with registered AF episodes [ Time Frame: Within the 12 weeks after randomization ] [ Designated as safety issue: No ]
Patients with symptomatic AF episodes [ Time Frame: Within the 12 weeks after randomization ] [ Designated as safety issue: No ]
Severity of AF and AF-like symptoms [ Time Frame: Within the 12 weeks after randomization ] [ Designated as safety issue: No ]
Premature study discontinuation [ Time Frame: Within the 12 weeks after randomization ] [ Designated as safety issue: No ]
Premature study discontinuation for all reasons including those where the patients must go off study prematurely as per protocol (ie. in case of cardioversion during the 1st study week, 2nd cardioversion after the 1st study week, addition of anti-arrhythmic drug, ablation or other surgical AF related intervention)
Patients with symptomatic episodes of bradycardia [ Time Frame: Within the 12 weeks after randomization ] [ Designated as safety issue: Yes ]
Patients with low heart rate (<60 bpm) [ Time Frame: Within the 12 weeks after randomization ] [ Designated as safety issue: Yes ]
