The effect of ranolazine and of low dose dronedarone when given alone and in combination at different dose levels on atrial fibrillation burden (AFB) over 12 weeks of treatment [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
Atrial Fibrillation Burden (AFB) is defined as the total time a subject is in atrial tachycardia/atrial fibrillation (AT/AF) expressed as a percentage of total recording time.

A Study to Evaluate the Effect of Ranolazine and Dronedarone When Given Alone and in Combination in Patients With Paroxysmal Atrial Fibrillation (HARMONY)
A Phase 2, Proof of Concept, Randomized, Placebo-Controlled, Parallel Group Study to Evaluate the Effect of Ranolazine and Dronedarone When Given Alone and in Combination on Atrial Fibrillation Burden in Subjects With Paroxysmal Atrial Fibrillation

The purpose of this study is to evaluate whether treatment with ranolazine or low dose dronedarone reduces atrial fibrillation burden (AFB) in subjects with paroxysmal atrial fibrillation (PAF), and whether combination therapy (ranolazine and low dose dronedarone) is superior to individual drug therapy in reducing AFB.

This phase 2 clinical trial will be conducted over 16 weeks and involves a Screening period (4 weeks) and a Treatment period (12 weeks). The final follow up visit will occur 2 weeks after the end of the Treatment period. Primary and Secondary endpoints will be evaluated according to treatment group, clinic visit period, and the overall Treatment period. Safety analyses will be conducted at each clinic visit, and include: cardiac rhythm monitoring, ECG testing, laboratory evaluation, and symptom and adverse event assessment.

Inclusion Criteria:

  • Males and females aged 18 years and older
  • Have the ability to understand and sign a written informed consent form, which must be obtained prior to initiation of study procedures
