E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine whether edoxaban (60/30 mg daily) compared to non-anticoagulant 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. |
Determinar si edoxaban (60/30 mg al día) en comparación con el tratamiento médico no anticoagulante (sin terapia antitrombótica o monoterapia antiplaquetaria) reduce el riesgo de accidente cerebrovascular (compuesto de accidente cerebrovascular isquémico, hemorrágico y no especificado) en pacientes con fibrilación auricular de alto riesgo (puntuación CHA2DS2-Vasc 2) con hemorragia intracraneal previa. |
|
E.2.2 | Secondary objectives of the trial |
i) To assess whether edoxaban (60/30 mg daily) compared to non-anticoagulant 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) Para evaluar si edoxaban (60/30 mg al día) en comparación con el tratamiento médico no anticoagulante (sin terapia antitrombótica o monoterapia antiplaquetaria) reduce el riesgo de muerte cardiovascular en pacientes deriesgo de fibrilación auricular participantes con hemorragia intracraneal previa.

E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Title: MRI Substudy (please refer to Appendix 2 of the ENRICH-AF protocol (global) 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, diffusion-weighted 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. |
Título: Subestudio de resonancia magnética (consulte el Apéndice 2 del protocolo ENRICH-AF (global) para obtener más detalles) Fecha: 2019 agosto19 Versión: 1.0
El subestudio tiene como objetivo investigar el potencial de modificación del efecto del tratamiento con marcadores basales de resonancia magnética de la enfermedad cerebral avanzada de los vasos pequeños, incluidas las micro hemorragias cerebrales y la siderosis superficial cortical, para el resultado primario del accidente cerebrovascular y el resultado de seguridad de la hemorragia intracraneal recurrente. Este subestudio se lanzará en centros selectos de participantes mundiales a fines del primer trimestre de 2020 y continuará al unísono hasta la finalización del estudio del ensayo ENRICH-AF más amplio. Se estima que entre 600 y 800 participantes se inscribirán en este subestudio.
Se obtendrá una resonancia magnética para cada participante antes de la aleatorización, a menos que existan contraindicaciones (es decir, marcapasos, cuerpos extraños metálicos no elegibles o hardware implantable, claustrofobia extrema no mitigada por sedación ligera, etc.).
Las imágenes relacionadas con el estudio deben obtenerse luego del consentimiento informado y antes de la aleatorización. |
