E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Evaluation of the efficacy of 3 doses of S066913 (5mg, 25mg, 100mg) versus placebo administered for 4 weeks on atrial fibrillation and/or atrial tachycardia burden in patients with paroxysmal atrial fibrillation who are potentially eligible for atrial fibrillation ablation and are implanted with insertable cardiac monitoring device. |
|
E.2.2 | Secondary objectives of the trial |
- Evaluation of the safety profile of S066913
- Evaluation of pharmacokinetic profile of S066913 |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Adult patients (except women of childbearing potential) potentially eligible for atrial fibrillation ablation (HRS/EHRA/ECAS 2012; AHA/ACC/HRS 2014 guidelines),
- In sinus rhythm at selection visit ) or sinus rhythm recorded within maximum 7 days since the onset of AF episode in case of ongiong paroxysmal AF),
- With at least one AF episode recorded by ECG , Holter, ICM or any other method to record ECG tracing within 18 months prior to selection visit, and with at least two other AF episodes within 30 days prior to selection visit which can be either typical symptomatic and written down in the medical history or asymptomatic and recorded by ECG, Holter, ICM or any other method to record ECG tracing,
- Eligible for and agreeing to receive ICM implantation following local guidelines and practice, or patients already implanted with an ICM
device of the same type as used in the study
- According to the report extracted from ICM interrogation performed locally by the investigator, AF/AT burden ≥ 1% and ≤ 70% and at least 3 episodes of AF in 4 weeks before inclusion |
|
E.4 | Principal exclusion criteria |
- AF secondary to a reversible cause,
- Persistent or permanent AF: at selection ; or history of persistent AF with the longest episode lasting more than 30 days; or ablation performed for paroxysmal or persistent AF less than 3 months before selection,
- Patient with more than one anti-arrhythmic drug stopped due to lack of efficacy (rather than intolerance or side effect), provided they were administered at recommended anti-arrhythmic dose,
- Patients previously treated with amiodarone that was stopped because of lack of efficacy, or amiodarone treatment within 3 months prior to selection,
- Corrected QT interval duration (Fridericia‟s formula) > 450 ms for male, 470 ms for female,
- High degree atrio-ventricular block (2nd degree or complete),
- Any history of sustained ventricular tachycardia, or resuscitated sudden death,
- Severe chronic heart failure,
- Recent acute coronary syndrome or revascularization
- Unreliable ICM recording
- Sustained ventricular tachycardia, asystole, or sustained bradycardia according to ICM interrogation |
