| E.1 Medical condition or disease under investigation |
| E.1.1 | Medical condition(s) being investigated |
Atrial fibrillation (AF) is one cause of stroke. Stroke rate is increased in patients with atrial high rate episodes (AHRE, an early stage of AF) as well, even if stroke rates are lower when compared to stroke rates in patients with diagnosed AF.
Prevention of stroke, systemic embolism or cardiovascular death in patients with AHRE but without diagnosed atrial fibrillation (AF) and in addition at least two stroke risk factors by intake of NOACs shall be investigated. |
|
| E.1.1.1 | Medical condition in easily understood language |
| AF is a common type of heart rhythm disorder. It carries the risk of increased clotting of blood particles which can occlude blood vessels. AHRE are atrial tachyarrhythmia episodes, a pre-stage of AF. |

| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
To demonstrate that oral anticoagulation with the NOAC edoxaban is superior to current therapy (antiplatelet therapy or no therapy depending on cardio-vascular risk) to prevent stroke, systemic embolism, or cardiovascular death in patients with AHRE but without overt AF and at least two stroke risk factors leading to a modified
CHA2DS2VASc score of 2 or more.

| E.2.2 | Secondary objectives of the trial |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
-Pacemaker, defibrillator or insertable cardiac monitor implanted for any reason with feature of detection of AHRE, implanted at least 2 months prior to randomisation.
-AHRE detection feature activated for adequate detection of AHRE
-AHRE (≥ 170 bpm atrial rate and ≥ 6 min duration) documented by the implanted device.
Any AHRE episode recorded is potentially eligible, but AHRE episodes detected in the first 2 months after implantation of a new device involving placement or repositioning of atrial electrodes are not eligible. AHRE episodes recorded in the first two months after a simple “box change” operation, i.e. exchange of a pacemaker or defibrillator device without exchange or repositioning of atrial electrodes, are eligible.
-Age ≥ 65 years
-In addition, at least one of the following cardiovascular conditions leading to a modified CHA2DS2VASc score of 2 or more: Age ≥ 75 years, heart failure (clinically overt or LVEF < 45%), arterial hypertension (chronic treatment for hypertension, estimated need for continuous antihypertensive therapy or resting blood pressure > 145/90 mmHg), diabetes mellitus, prior stroke or transient ischemic attack (TIA), vascular disease (previous myocardial infarction, peripheral, carotid/cerebral, or aortic plaques on transesophageal echocardiogram [TEE]).
-Provision of signed informed consent |
|
| E.4 | Principal exclusion criteria |
-Any disease that limits life expectancy to less than 1 year.
-Participation in another controlled clinical trial, either within the past two months or still ongoing.
-Previous participation in the present trial NOAH - AFNET 6.
-Drug abuse or clinically manifest alcohol abuse.
-Any history of overt AF or atrial flutter.
-Indication for oral anticoagulation (e.g. deep venous thrombosis).
-Contraindication for oral anticoagulation in general.
-Contraindication for edoxaban as stated in the current SmPC.
-Indication for long-term antiplatelet therapy other than acetylsalicylic acid or a need for treatment with any antiplatelet agent in addition to edoxaban, especially dual antiplatelet therapy (DAPT). Patients with a transient requirement for DAPT (e.g. after receiving a stent) will be eligible when the need for DAPT is no longer present.
-Acute coronary syndrome, coronary revascularisation (PCI or bypass surgery), or overt stroke within 30 days prior to randomisation.
-End stage renal disease (creatinine clearance (CrCl) < 15 ml/min as calculated by the Cockcroft-Gault method)
Legal exclusion criterion (applicable in countries where legally required)
-All persons exempt from participation in a clinical trial by law.

outcome events is provided in Appendix III of the study protocol.
|
|
| E.5.1.1 | Timepoint(s) of evaluation of this end point |
Evaluation of stroke, systemic embolism, or cardiovascular death by CRO: within 24 hours after SAE reporting by the investigator.
Evaluation of stroke, systemic embolism, or cardiovascular death by an Critical Event Committee (CEC) during the course of the trial on a regular basis (monthly). |
|
| E.5.2 | Secondary end point(s) |
1. components of the primary outcome,
2. major adverse cardiac events (MACEs: cardiovascular death, myocardial infarction, acute coronary syndrome (ACS), PCI, CABG)
3.stroke or systemic arterial embolism
4. all-cause death,
5. major bleeding events according to the International Society on Thrombosis and Haemostasis (ISTH) definitions,
6. quality of life changes at 12 and 24 months compared to baseline (assessed by EQ-5D including its visual-analogue scale and by the Karnofsky scale),
7. patient satisfaction at 12 and 24 months compared to baseline (assessed by modified EHRA score and PACT-Q))
8. cost effectiveness and health resource utilisation estimated by quantification of relevant events, interventions, nights spent in hospital and cardiovascular therapies,
9. changes of autonomy status only in patients with stroke during study participation, potentially assessed at each clinical follow-up visit by modified Rankin scale; a maximum of 2 subsequent assessments in follow-up per patient with stroke should be performed,
