Enrollment Criteria

Inclusion Criteria:

Recent ESUS (between 7 days and 6 months), defined as:

  1. Recent ischemic stroke (including transient ischemic attack with positive neuroimaging) visualized by brain imaging that is not lacunar, and
  2. Absence of cervical carotid atherosclerotic stenosis > 50% or occlusion, and
  3. No atrial fibrillation after ≥ 24-hour cardiac rhythm monitoring (at least 20 hrs acceptable), and
  4. No intra-cardiac thrombus on either transesophageal or transthoracic echocardiography, and
  5. No other specific cause of stroke (i.e. arteritis, dissection, migraine/vasospasm, drug abuse)

Exclusion criteria:

  1. Severely disabling stroke (modified Rankin score ≥4 at screening)
  2. If imaging of intracranial arteries is performed by CT or MR angiography or transcranial Doppler: > 50% luminal stenosis or occlusion in arteries supplying the area of ischemia

  7. Indication for chronic antiplatelet therapy or chronic therapy with NSAID for a non-stroke indication
  8. Hypersensitivity or other contraindication for ASA or rivaroxaban
  9. Active bleeding, major bleeding within last 6 months, high risk for serious bleeding contraindicating anticoagulant or antiplatelet therapy or history of primary intracranial hemorrhage
  10. Hepatic disease associated with coagulopathy (PTT>normal range) and clinically relevant bleeding risk including cirrhotic patients with Child Pugh B and C
  11. Estimated GFR< 30 mL/min/1.73 m2 as assessed at local laboratory within 1 month of screening
  12. Life expectancy less than 6 months
  13. Concomitant use of strong inhibitors of both cytochrome P450 isoenzyme 3A4 (CYP3A4) and P-glycoprotein (P-gp), i.e., human immunodeficiency virus protease inhibitors and the following azole-antimycotics agents: ketoconazole, itraconazole, voriconazole, or posaconazole, if used systemically
  14. Female of childbearing potential who are not surgically sterile, or, if sexually active not willing to use adequate contraceptive measures, and pregnant or breast feeding women
