E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate that the strategy with single antiplatelet therapy (SAPT) is not inferior to the current standard antiplatelet therapy (DAPT) after LAA closure regarding the cumulative incidence of the net composite endpoint, including death, thrombotic complications and bleeding events, at 6 months. |
Dimostrare che la strategia con singola terapia antipiastrinica (SAPT) non è inferiore all'attuale terapia antipiastrinica standard (DAPT) dopo la chiusura della LAA per quanto riguarda l'incidenza cumulativa dell'endpoint composito netto, inclusi morte, complicanze trombotiche ed eventi di sanguinamento, a 6 mesi. |
|
E.2.2 | Secondary objectives of the trial |
Compared to DAPT, SAPT use is associated with a similar incidence of ischemic events and a significantly lower incidence of bleeding complications at 6 months. |
Rispetto al DAPT, l'uso di SAPT è associato a un'incidenza simile di eventi ischemici e un'incidenza significativamente inferiore di complicanze emorragiche a 6 mesi. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
-Men or women aged =18 years signing a specific informed consent -Patients with a planned percutaneous LAA closure; -Patients with documented non-valvular AF, irrespective of the type (paroxysmal, permanent, persistent), and CHA2DS2-VASc score =2 -Patients considered unsuitable for long-term oral anticoagulant therapy due to a high bleeding risk. Patients will be judged unsuitable for anticoagulation because of bleeding-prone comorbidities, history of previous bleeding (with or without anticoagulant treatment) or an expected low adherence to therapy. -Patient’s availability to undergo the follow-up visits scheduled for the study -Negative pregnancy testing (if applicable), performed at the time of enrollment. |
- Uomini o donne di età =18 anni che hanno firmato un consenso informato specifico - Pazienti per cui è già stata programmata procedura di chiusura dell’Auricola sinistra - Pazienti con fibrillazione atriale (FA) non valvolare documentata, indipendentemente dal tipo (parossistico, permanente, persistente) e punteggio CHA2DS2-VASc =2 - Pazienti considerati non idonei alla terapia anticoagulante orale a lungo termine a causa di un alto rischio di sanguinamento. I pazienti saranno giudicati inadatti alla terapia anticoagulante a causa di comorbidità soggette a sanguinamento, storia di sanguinamento precedente (con o senza trattamento anticoagulante) o un'attesa scarsa aderenza alla terapia. - Disponibilità del paziente a sottoporsi alle visite di follow-up previste per lo studio - Test di gravidanza negativo (se applicabile), eseguito al momento dell'iscrizione. |
|
E.4 | Principal exclusion criteria |
-CHADS-VAsc score 0-1 -Requirement for on-going therapy with clopidogrel at the time of screening evaluation (e.g. current therapy with clopidogrel at the time of the screening evaluation will be an exclusion criterion) -Known hypersensitivity to the study drugs (aspirin or clopidogrel) -Patients deemed to be unsuitable for at least 6 months antiplatelet therapy (SAPT or DAPT) because of a recent (<1 month) major bleeding event -Planned oral anticoagulant therapy after the procedure -Moderate to severe mitral stenosis -Mechanical heart prosthetic valve -Active endocarditis -Active bleeding -Myocardial infarction or percutaneous coronary intervention <6 months -Major surgery within one month -Intracranial neoplasm, aneurysm or arterio-venous malformation -Platelet count <50,000/µL -Recent stroke (<1 month) -Fibrinolytic therapy within 10 days -Baseline hemoglobin <9 g/dL -Pregnant woman -Breast-feeding -Women unavailable to use contraception during the study period |
- CHADS-VAsc score 0-1 - Pazienti in terapia con clopidogrel al momento dello screening (es. la terapia in corso con clopidogrel al momento dello screening costituirà un criterio di esclusione) - Nota ipersensibilità ai farmaci usati nello studio (aspirina o clopidrogel) - Pazienti impossibilitati alla terapia antipiastrinica (SAPT o DAPT) per 6 mesi a causa di un elevato rischio di sanguinamento recente (<1 mese) - Pazienti che riceveranno una terapia anticoagulante dopo la procedura - Stenosi mitralica da moderata a severa - Impianto di valvola cardiaca meccanica - Endocardite in corso - Sanguinamenti in corso - Infarto Miocardico (MI) o intervento coronarico percutaneo (PCI) nei 6 mesi precedenti - Interventi chirurgici maggiori entro un mese - Neoplasia, aneurisma o malformazione arterio-venosa intracranica - Conta piastrinica <50,000/µL - Recente ictus (<1 mese) -Terapia fibrinolitica entro 10 giorni - Emoglobina basale <9 g/dL - Donne incinte - Donne in allattamento - Donne fertili impossibilitate ad utilizzare contraccettivi durante lo studio |

E.5 End points |
E.5.1 | Primary end point(s) |
Primary endpoint will be the 6-month incidence in the two arms (SAPT versus DAPT) of the net composite endpoint including all-cause death, device-related thrombosis (DRT) (at 3- or 6-month transesophageal echocardiography (TEE)), ischemic stroke, systemic embolic events (SEE) or BARC classification bleeding =3 (7). An independent board for clinical event adjudication and data safety monitoring will be created. |
L'endpoint primario sarà l'incidenza a 6 mesi nei due bracci di trattamento (SAPT versus DAPT) dell'endpoint composito netto comprendente morte per tutte le cause, trombosi correlate al dispositivo (DRT) (all'ecocardiografia transesofagea (TEE) eseguita a 3 o 6 mesi), ictus ischemico, eventi embolici sistemici (SEE) o sanguinamento secondo la classificazione BARC =3 (7). Verrà istituito un comitato indipendente per la valutazione degli eventi clinici e il monitoraggio della sicurezza dei dati. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
The following secondary endpoints will be separately considered and compared in the two arms: -DRT at 3 and 6 months by TEE -Any-cause death -Incidence of ischemic stroke or SEE at 3 and 6 months -Incidence of any bleeding at 3 and 6 months -Incidence of BARC classification bleeding =3 at 3 and 6 months |
I seguenti endpoint secondari verranno considerati e confrontati separatamente nei due bracci: - DRT a 3 e 6 mesi secondo la valutazione all’esame TEE - Morte per qualsiasi causa - Incidenza di ictus ischemico o SEE a 3 e 6 mesi - Incidenza di qualsiasi sanguinamento a 3 e 6 mesi - Incidenza di sanguinamenti secondo la classificazione BARC =3, valutata a 3 e 6 mesi |
