Outcome Measures

Primary Outcomes (1)

  • Imaging Endpoint: Occurrence of at least one new ischemic lesion at 12 months after study drug initiation when compared to baseline MRI before study drug initiation

    The primary endpoint will be the occurrence of at least one new ischemic lesion identified by magnetic resonance imaging (axial T2-weighted fluid attenuated inversion recovery MRI (FLAIR) and/or axial diffusion weighted MRI (DWI)) at 12 months when compared to the baseline MRI (FLAIR, DWI) obtained at the time of study drug initiation. MRI at 12 months will be directly compared with the baseline MRI to assess for new ischemic lesions.

    12 months

Secondary Outcomes (5)

  • Combination of recurrent ischaemic stroke, hemorrhagic stroke, systemic embolism

    12 months

  • Combination of major adverse cardiovascular events (MACE) including recurrent stroke, myocardial infarction and cardiovascular death

    12 months

  • Combination of major and clinically relevant non-major bleedings defined according to ISTH criteria

    12 months

  • Change of cognitive function (MOCA)

    12 months

  • Life quality (EQ-5D)

    12 months

Study Arms (2)

Apixaban

EXPERIMENTAL

You may qualify if:

  • ESUS must be defined according to following criteria:
  • Stroke detected by CT or MRI that is not lacunar
  • Absence of extracranial or intracranial atherosclerosis causing ≥50% luminal stenosis in arteries supplying the area of ischaemia
  • No major-risk cardioembolic source of embolism
  • No other specific cause of stroke identified
  • \* At least one of the following non-major but suggestive risk factors for cardiac embolism:
  • LA size \>45mm (parasternal axis)
  • spontaneous echo contrast in LAA
  • LAA flow velocity \<=0.2m/s
  • atrial high rate episodes
  • CHA2DS2-Vasc score \>=4
  • persistent foramen ovale

  • Women of childbearing potential (WOCBP) must be using an adequate method of contraception.

You may not qualify if:

  • Clear stroke-/non-stroke-indication for concomitant long-term therapy with antiplatelets (e.g. acetylsalicylic acid (ASA), Clopidogrel, or Prasugrel) or with non-steroidal anti-inflammatory drugs (NSAID).
  • Concomitant systemic therapy with strong inhibitors of cytochrome P450 3A4 (CYP3A4) and P-glycoprotein (P-gp), i.e. azole antimycotics and human immunodeficiency virus (HIV)-protease inhibitors.
  • Contraindication to investigational medications
  • Planned or likely therapy with fibrinolytic agents within 48 hours of first study medication
  • History of intracranial, intraocular, spinal, retroperitoneal or atraumatic intra-articular bleeding
  • Gastrointestinal bleed or major surgery within 3 months
  • Planned or likely revascularization (any angioplasty or vascular surgery) within the next 3 months
