Multicenter, Randomized, Double-blind, Double-dummy, Active-comparator, Event-driven, Superiority Phase III Study of Secondary Prevention of Stroke and Prevention of Systemic Embolism in Patients With a Recent Embolic Stroke of Undetermined Source (ESUS), Comparing Rivaroxaban 15 mg Once Daily With Aspirin 100 mg

This study will enroll patients who recently had a brain attack (stroke) and in whom no clear cause of the stroke could be identified. These strokes are likely due to a blood clot and therefore, can be called embolic stroke of undetermined source (ESUS). The study will compare 2 blood thinners; patients will be randomly assigned to either Rivaroxaban 15 mg or Aspirin 100 mg and the study is intended to show, if patients given Rivaroxaban have fewer blood clots in the brain (stroke) or in other blood vessels.

Key Eligibilities:
-Ages Eligible for Study: 50 Years and older.
-Recent ESUS (between 7 days and 6 months).

Exclusion Criteria:
-Severely disabling stroke (modified Rankin Score ≥4).
-Indication for chronic anticoagulation or antiplatelet therapy.
