E.2.1 | Main objective of the trial |
To determine if the use of apixaban in patients with SCAF will reduce the incidence of stroke and systemic embolism compared to aspirin. |

|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Permanent pacemaker or defibrillator (with or without resynchronization) or insertable cardiac monitor capable of detecting SCAF
2. At least one episode of device-detected SCAF ≥ 6 minutes in duration (Atrial rate > 175/min if an atrial lead is present), but no single episode > 24 hours in duration at any time prior to enrollment. SCAF requires electrogram confirmation (at least one episode) unless ≥ 6 hours in duration
3. Age ≥ 18 years
4. CHA2DS2-VASc score of ≥ 4 |
1. Presenza di PM permanente o defibrillatore (con o senza ri-sincronizzazione) o MCI in grado di rilevare episodi di FASC.
2. Almeno un episodio di FASC, rilevato dal dispositivo, della durata di almeno 6 minuti (con frequenza atriale > 175 / min se è presente un elettrocatetere atriale), ma nessun singolo episodio di FASC della durata maggiore di 24 ore in qualsiasi momento prima dell'arruolamento. La FASC richiede la conferma diagnostica mediante l’esecuzione di un elettrocardiogramma (almeno un episodio) a meno che la durata non sia superiore a 6 ore.
3. Età ≥ 18 anni.
4. Punteggio CHA2DS2-VASc ≥ 4.

2. Mechanical valve prosthesis, recent (within past 6 months) deep vein thrombosis or pulmonary embolism or other condition requiring treatment with an anticoagulant
3. Allergy to aspirin or apixaban
4. Severe renal insufficiency (serum creatinine > 2.5 mg/dL [221 μmol/L] or a calculated creatinine clearance < 25 ml/min)
5. Serious bleeding in the last 6 months or at high risk of bleeding (this includes, but is not limited to: prior intracranial hemorrhage, active peptic ulcer disease, clinically significant thrombocytopenia or anemia, recent stroke within past 10 days, documented hemorrhagic tendencies or blood dyscrasias)
6. Moderate to severe hepatic impairment
7. Ongoing need for combination therapy with aspirin and clopidogrel (or other combination of two platelet inhibitors)
8. Meets criteria for requiring lower dose of apixaban AND also has ongoing need for strong inhibitors of both CYP3A4 and P-glycoprotein (e.g., ketoconazole, itraconazole, ritonavir or clarithromycin)
9. Ongoing need for strong dual inducers of both CYP3A4 and P-glycoprotein (e.g., rifampin, carbamazepine, phenytoin, St. John’s wort)
10. Received an investigational drug in the past 30 days
11. Participants considered by the investigator to be unsuitable for the study for any of the following reasons:
Not agreeable for treatment with either aspirin or apixaban or anticipated to have poor compliance on study drug treatment
Unwilling to attend study follow-up visits
Life expectancy less than 2 years due to concomitant disease
12. Women who are pregnant, breast-feeding or of child-bearing potential without an acceptable form of contraception in place (sterilization, abstinence or other method with less than 1% failure rate) |
1. Presenza di Fibrillazione Atriale clinicamente evidente documentata mediante ECG di superficie (a 12 derivazioni o con telemetria o mediante Holter-ECG) della durata di almeno 6 minuti, con o senza sintomi clinici.
2. Presenza di protesi valvolare meccanica, presenza di trombosi venosa profonda recente (nei 6 mesi precedenti) o embolia polmonare recente (nei 6 mesi precedenti) o altre condizioni che richiedono trattamento con un anticoagulante.
3. Allergia ad aspirina o apixaban.
4. Severa insufficienza renale (creatinina sierica > 2,5 mg / dL [221 mcmol/L] o clearance della creatinina calcolata < 25 ml / min).
5. Sanguinamento grave negli ultimi 6 mesi o condizioni ad alto rischio di sanguinamento (inclusi ma non limitati a: precedente emorragia intracranica, ulcera peptica attiva, trombocitopenia o anemia clinicamente significative, ictus recente nei 10 giorni precedenti, documentate diatesi emorragica o discrasie ematiche).
6. Insufficienza epatica da moderata a severa.
7. Necessità continuativa di doppia terapia antiaggregante con aspirina e clopidogrel (o altra combinazione di due inibitori piastrinici).
8. Necessità della dose più bassa di apixaban associata alla necessità continuativa di forti inibitori del CYP3A4 e P-glicoproteina (per esempio, ketoconazolo, itraconazolo, ritonavir o claritromicina).
9. Necessità continuativa di forti induttori del CYP3A4 e P-glicoproteina (per esempio, rifampicina, carbamazepina, fenitoina, Iperico- Erba di San Giovanni).
10. Assunzione di un farmaco sperimentale negli ultimi 30 giorni.
11. Soggetti considerati dallo sperimentatore non adatti allo studio per uno dei seguenti motivi:
1- non idoneità al trattamento con aspirina o apixaban o prevedibile scarsa compliance all’assunzione del farmaco in studio;
2- indisponibilità a partecipare alle visite di follow-up;
3- aspettativa di vita inferiore ai 2 anni a causa di malattie concomitanti.
12. Donne in stato di gravidanza, in allattamento o in età fertile senza una forma accettabile di contraccezione (sterilizzazione, astinenza o altro metodo con un tasso di fallimento inferiore all’1%).
