Overview

Brief Summary

To assess whether intravenous thrombolysis with tenecteplase 0.25 mg/kg improves functional outcome after acute ischemic stroke in patients taking direct oral anticoagulants compared to placebo.

Eligibility Criteria

Ages
18 years to 65+ years (18-64 Years, 65+ Years)
Accepts Healthy Volunteers
Yes

Inclusion Criteria

  • Age ≥ 18 years
  • Clinical diagnosis of acute stroke with disabling deficit
  • National Institutes of Health Stroke Scale (NIHSS) score at least 2
  • Recent intake (within 48 hours prior to enrolment) of a direct oral anticoagulant (apixaban, rivaroxaban, edoxaban, or dabigatran)
  • No evidence of any intracranial haemorrhage on cerebral imaging (CT or MRI) performed after stroke onset and no earlier than 60 minutes before enrolment
  • Stroke symptoms not known to have been present for > 6 h
  • For patients not known to have been awake and without acute stroke symptoms within 4.5 hours prior to enrolment, additional imaging criteria must be satisfied: a) If stroke symptoms are known to have been present for > 4.5 h (late time window): core/penumbra mismatch on MR or CT perfusion imaging; b) If stroke symptoms are not known to have been present for > 4.5 h (unknown time window): core/penumbra mismatch on MR or CT perfusion imaging; or DWI/FLAIR mismatch on MR imaging.

Exclusion Criteria

  • Contraindication to intravenous thrombolysis, except DOAC therapy
  • Reversal or planned reversal of anticoagulation with idarucizumab or andexanet alfa
  • Concomitant therapy with antithrombotic medications, except DOACs
  • Anticipated stenting of cervical or intracranial artery within 12 hours
  • Anticipated coronary angioplasty within 12 hours
  • Any anticipated surgical intervention within 12 hours
  • Significant pre-stroke disability (mRS > 3)
