E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine whether edoxaban (60/30 mg daily) compared to nonanticoagulant medical therapy (either no antithrombotic therapy or antiplatelet monotherapy) reduces the risk of stroke (composite of ischemic, hemorrhagic and unspecified stroke) in high-risk atrial fibrillation (CHA2DS2-VASc score =2) patients with previous intracranial hemorrhage. |
Valutare se l’Edoxaban (60/30 mg/die), rispetto alla terapia medica senza anticoagulante (nessuna terapia antitrombotica o monoterapia antipiastrinica), riduce il rischio di ictus (composto da ictus ischemico, emorragico e non specificato) nei pazienti ad alto rischio di fibrillazione atriale (punteggio CHA2DS2-VASc =2) con pregressa emorragia intracranica. |
|
E.2.2 | Secondary objectives of the trial |
i) To assess whether edoxaban (60/30 mg daily) compared to nonanticoagulant medical therapy (either no antithrombotic therapy or antiplatelet monotherapy) reduces the risk of cardiovascular death in high-risk atrial fibrillation participants with previous intracranial hemorrhage.
ii) To assess whether edoxaban (60/30 mg daily) is associated with increased risk of major hemorrhage compared to standard of care (either no antithrombotic therapy or antiplatelet monotherapy). |
i) Valutare se l’Edoxaban (60/30 mg/die), rispetto alla terapia medica senza anticoagulante (nessuna terapia antitrombotica o monoterapia antipiastrinica), riduce il rischio di morte cardiovascolare nei pazienti ad alto rischio di fibrillazione atriale con pregressa emorragia intracranica.
ii) Valutare se edoxaban (60/30 mg al giorno) sia associato ad un aumento del rischio di emorragia maggiore rispetto allo standard di cura (senza terapia antitrombotica o monoterapia antiaggregante piastrinica). |

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Other types of substudies Specify title, date and version of each substudy with relative objectives: Title: MRI Substudy (please refer to Appendix 2 of the ENRICH-AF protocol for further details) Date: 2019August19 Version: 1.0
The substudy aims to investigate the potential for treatment effect modification with baseline MRI markers of advanced cerebral small vessel disease, including cerebral microbleeds and cortical superficial siderosis, for the primary outcome of stroke and safety outcome of recurrent intracranial hemorrhage. This substudy will be launched at select global participating centers by the end of 1st quarter of 2020 and will continue in unison until study termination of the broader ENRICH-AF trial. An estimated 600-800 participants will be enrolled in this substudy. An MRI will be obtained for each participant before randomization, unless contraindications exist (i.e. pacemakers, ineligible metallic foreign bodies or implantable hardware, extreme claustrophobia unmitigated by light sedation, etc.). Mandated MRI sequences including T2*-gradient echo or susceptibility weighted sequences, diffusionweighted imaging, T1-weighted, T2-weighted, and FLAIR. Study-related MRIs must be obtained following informed consent and prior to randomization. T2*-gradient echo or susceptibility weighted sequences should be prioritized as the initial sequence during acquisition, followed by FLAIR, T1-weighted, diffusion-weighted imaging and T2-weighted sequences.

Altre tipologie di sottostudi specificare il titolo, la data e la versione di ogni sottostudio con i relativi obiettivi: Titolo: MRI Substudy (please refer to Appendix 2 of the ENRICH-AF protocol for further details) Data: 2019August19 Versione: 1.0
Il sottostudio ha lo scopo di indagare se specifici marcatori di malattie dei piccoli vasi in stadio avanzato e inclini ad emorragia (ad es. micro-sanguinamenti cerebrali e siderosi superficiale corticale) evidenziati con la Risonanza Magnetica interferiscono con l’effetto del trattamento dello studio assegnato rispetto alle ricadute di ictus e rispetto alla sicurezza dell'emorragia intracranica ricorrente. Questo sottostudio sarà effettuato in selezionati centri partecipanti a livello globale e continuerà in parallelo fino alla conclusione dello studio principale ENRICH-AF. Si stima che circa 600-800 partecipanti saranno arruolati in questo sottostudio. Nei centri partecipanti al sottostudio MRI, sarà ottenuta una risonanza magnetica per ogni partecipante prima della randomizzazione, a meno che non esistano controindicazioni (ad esempio pacemaker, corpi estranei metallici non idonei o hardware impiantabile, claustrofobia estrema non attenuata da leggera sedazione, ecc.). Sequenze di risonanza magnetica obbligatorie sono: T2*-gradient echo o susceptibility weighted (SWI), diffusion weighted imaging (DWI), Pesatura in T1, Pesatura in T2 e FLAIR. Le risonanze magnetiche correlate allo studio devono essere ottenute previo consenso informato e prima della randomizzazione. Il T2*-gradient echo o le sequenze susceptibility weighted devono avere la priorità come sequenza iniziale durante l'acquisizione, seguite da FLAIR, Pesatura in T1, diffusion weighted imaging e Pesatura in T2
