NCT04733742

Brief Summary

The purpose of this trial is to investigate whether intravenous rhTNK-tPA prior to endovascular treatment can improve 90-day functional outcome of stroke patients with large vessel occlusion who are thrombolysis-eligible within 4.5 hours of symptom onset.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Aged 18 years or older;
  • Patient with acute ischemic stroke who is eligible for intravenous thrombolysis treatment within 4.5 hours of time last known well;
  • No significant prestroke functional disability: for age \<80 years, prestroke modified Rankin scale (mRS) ≤2; for age ≥80 years, prestroke mRS ≤1;
  • MCA-M1 or -M2, basilar artery, or posterior cerebral artery-P1 occlusion proved by CTA/MRA;
  • EVT is planned by clinical care team;
  • Written informed consent is obtained from patients and/or their legal representatives.

You may not qualify if:

  • Intracranial hemorrhage on baseline CT or MR
  • Contraindication to intravenous thrombolytics
  • Already received intravenous thrombolytic after index stroke
  • Known pregnancy, or breastfeeding, or serum beta human chorionic gonadotropin test is positive on admission
  • Contraindication to radiographic contrast agents, nickel, titanium metals or their alloys
  • Current participation in another investigational drug clinical trial
  • Arterial tortuosity and/or other arterial disease that would lead to unstable access platform or prevent the thrombectomy device from reaching the target vessel
  • Patient with a preexisting neurological or psychiatric disease that would confound the outcome assessments
  • Patient with occlusions in two or more vascular territories (e.g. bilateral territories, or anterior and posterior circulation)
  • Mass effect or intracranial neoplasm on baseline CT or MR (except small meningioma)
  • Intracranial arteriovenous malformation or aneurysm on baseline CT or MR angiography
  • Any terminal disease with a life expectancy less than half a year
  • Unlikely to be available for follow-up at 90 days.
