Early Versus Late Initiation of Direct Oral Anticoagulants in Post-ischaemic Stroke Patients With Atrial fibrillatioN (ELAN): an International, Multicentre, Randomised-controlled, Two-arm, Assessor-blinded Trial
In Brief
A clinical study evaluating Early treatment with Rivaroxaban (Xarelto®), Dabigatran (Pradaxa®), Apixaban (Eliquis®) or Edoxaban (Lixiana®) and Late treatment with Rivaroxaban (Xarelto®), Dabigatran (Pradaxa®), Apixaban (Eliquis®) or Edoxaban (Lixiana®) for Ischaemic Stroke. Completed, enrolled 2,013 participants across 98 sites in 15 countries.
Detailed Summary
When to start anticoagulation in patients with an acute ischaemic stroke and atrial fibrillation (AF) is a relevant unanswered question in clinical practice. Direct oral anticoagulants (DOACs) are highly effective for secondary stroke prevention in these patients, but DOACs were never initiated \<7 days after stroke onset in recent trials. The ELAN trial will determine the net benefit of early versus late initiation of DOACs in patients with acute ischaemic stroke related to AF. The main objective is to estimate the net benefit of early versus late initiation of DOACs in patients with acute ischaemic stroke related to AF. The secondary objectives are to assess all vascular events and all-cause mortality after early initiation of DOACs in patients with acute ischaemic stroke related to AF compared to late initiation.

Timeline
Interventions
Early treatment will be started within 48 hours after symptom onset (minor and moderate ischaemic stroke) or at day 6 + 1 day after symptom onset (major ischaemic stroke)
Patients in the control arm will receive late treatment as per current recommendations (i.e. minor ischaemic stroke after day 3 + 1 day, moderate ischaemic stroke after day 6 + 1 day and major ischaemic stroke after day 12 + 2 day).
