EdoxabaN foR IntraCranial Hemorrhage Survivors With Atrial Fibrillation

Status Recruiting

Clinical Trial Summary

To assess whether edoxaban (60/30 mg daily) compared to non-antithrombotic 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 ≥2) patients with previous intracranial hemorrhage.

Clinical Trial Description

The EdoxabaN foR IntraCranial Hemorrhage survivors with Atrial Fibrillation (ENRICH-AF) study is a prospective, randomized open-label, blinded end-point (PROBE), investigator-initiated, study that will define the efficacy and safety of edoxaban compared with non-anticoagulant medical therapy (no antithrombotic therapy or antiplatelet monotherapy) for stroke prevention in high-risk AF patients and previous intracranial hemorrhage. Intracranial hemorrhage includes intracerebral hemorrhage, intraventricular hemorrhage, subarachnoid hemorrhage and subdural hematoma. Recruitment will occur at 250-300 stroke research centres in North and South America, Europe and Asia over 24 months, where 1200 adult participants with high-risk AF (CHA2DS2-VASc score ≥2) and previous spontaneous or traumatic intracranial hemorrhage (while on or off antithrombotic therapy) will be randomly assigned to receive edoxaban 60/30 mg daily or to non-anticoagulant medical therapy (no antithrombotic therapy or antiplatelet monotherapy). Consenting participants will be followed to a common study end-date in this event-driven trial once 123 primary efficacy events (stroke) have accrued; anticipated to be about 12 months after the end of recruitment. ENRICH-AF will assess the safety and efficacy of anticoagulant therapy in AF participants after intracranial hemorrhage, an area where there currently exists huge interest within the stroke and cardiology research communities. Demonstrating safety comparable with non-anticoagulant medical therapy in AF patients who are particularly at high risk for intracranial hemorrhage is likely to have a more far-reaching clinical impact than solely within the proposed study population. ENRICH-AF will be the "ultimate safety test" of anticoagulation of AF patients, providing reassuring evidence favoring more widespread use of anticoagulation for stroke prevention in AF patients. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
