NCT03433235

Brief Summary

The investigators hypothesize that earlier initiation of edoxaban in AF-related stroke patients may significantly reduce the early recurrence of ischemic stroke, compared with conventional strategy of anticoagulation following 1-3-6-12 rule. To expedite the verification of the hypothesis, the investigators are planning to use diffusion weighted imaging (DWI), which has been reported to be a surrogate to predict both short-term and long-term prognosis after stroke, to detect the recurrent ischemic events. Because data on the early anticoagulation in patients with AF-related stroke are limited, the investigators decided to perform a pilot study before establishing an appropriate clinical trial protocol. This study will help estimate the efficacy and safety of early administration of edoxaban, and determine the sample size of a following clinical trial. To ensure the safety in this pilot exploration, the investigators will not include patients with severe ischemic strokes, who are often prone to experience hemorrhagic transformation in the acute post-stroke period.

Study Arms (2)

Early edoxaban initiation group

EXPERIMENTAL

Low dose of edoxaban (15 or 30 mg) once daily from Day 2, then standard dose of edoxaban (30 or 60 mg) according to '3-6' rule.

Drug: Edoxaban

Conventional edoxaban initiation group

ACTIVE COMPARATOR

No antithrombotic treatment† -- then standard dose of edoxaban (30 or 60 mg) according to '3-6' rule.

Drug: Edoxaban

Interventions

1-3-6-12 rule\* Anticoagulation in patients with acute ischemic stroke and atrial fibrillation can be initiated from the following days after stroke event. After 1 day: transient ischemic attacks After 3 days: mild ischemic strokes (NIHSS \<8) After 6 days: moderate ischemic strokes (NIHSS 8-16) After 12 days: severe ischemic strokes (NIHSS \>16) \- NIHSS: National Institute of Health Stroke Scales

Eligibility Criteria

Age20 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Acute ischemic strokes (\< 48 h from symptom onset) showing ischemic lesions confirmed by DWI, which are attributable to atrial fibrillation
  • Evidence of persistent or paroxysmal atrial fibrillation (already known or newly detected)
  • Age ≥20 y
  • Patients who provided informed consent

You may not qualify if:

  • Transient ischemic attack with no DWI lesions or severe ischemic strokes (NIHSS \>16)
  • Significant hemorrhagic transformation (parenchymal hematoma type I or type II by the ECASS definition or those accompanying with worsening of an existing focal neurological deficit \[NIHSS ≥4\])10 on baseline MRI
  • Mechanical heart valve, rheumatic heart valve disease, or any other conditions requiring strong anticoagulation such as vitamin K antagonist or heparin treatment
  • Concomitant significant atherosclerotic stenosis (\>50%) in the proximal arteries, which are possibly responsible for stroke lesions
  • Recent (\<3 months) history of cerebral bleeding
  • Active internal bleeding or clinically significant bleeding
  • Severe anemia (Hb \<10 g/dL) or bleeding diathesis (platelet count \<100,000/uL or PT-INR \>1.7) (If there is no active bleeding sign, it is permitted to enroll Hb \<9 g/dL , platelet count \<70,000/uL)
  • Uncontrolled hypertension: persistent systolic pressure \>180 mmHg or diastolic pressure \>110 mmHg
  • Active, advanced medical diseases (liver, kidney, pulmonary disease or cancer) with a life expectancy \<6 months
  • Renal impairment (CrCl \<30 mL/min) or undergoing Hemodialysis (or Peritoneal Dialysis)
  • Treatment with a strong inducer of p-glycoprotein (carbamazepine, dexamethasone, doxorubicin, nefazodone, pentobarbital, phenobarbital, prazocin, rifampin, St.John's wort, tenofovir, tipranavir, trazodone, vinblastine)
  • Contraindication to MRI
  • Pregnancy, breast-feeding or having a plan to be pregnant
  • Participation in the other investigational drug trials simultaneously or within 3 months before the first administration of the study medication. Observational studies without an intervention (eg study medication) are allowed.
  • Any clinical conditions (eg abnormal lab tests) unsuitable for undergoing clinical trials at the discretion of the clinical investigators
  • +15 more criteria
