About

The purpose of this study is to evaluate the safety and efficacy of Human Urinary Kallidinogenase combined with endovascular therapy in acute ischemic stroke (AIS) patients with large vessel occlusion.

Full description

A prospective, randomized, double-blind, placebo-controlled, multi-center study of Human Urinary Kallidinogenase or Placebo, combined with endovascular therapy for AIS patients with large vessel occlusion.

Approximately 120 eligible subjects will be randomized (1:1) to receive one of the following treatments for 10 days:

  • Human Urinary Kallidinogenase combined with endovascular therapy (non-bridged)
  • Placebo combined with endovascular therapy (non-bridged) Primary efficacy of Human Urinary Kallidinogenase will be evaluated at 90±7 days.

The safety of Human Urinary Kallidinogenase will be evaluated through 90±7 days.

End of study evaluation will occur at day 90±7 or premature discontinuation.

Inclusion criteria

  1. Participant with acute anterior circulation ischemic stroke receiving endovascular treatment within 24 hours (non-bridged).
  2. Age ≥18 years old.
  3. The mRS score was 0-1 before onset.
  4. ASPECT score of infarction on emergency CT ≥7.
  5. Emergency CTA indicating AIS with large vessel occlusion (internal carotid artery, M1 or M2 segment of middle cerebral artery).

  2. CT or MRI showed intracranial hemorrhagic diseases (such as hemorrhagic stroke, epidural hematoma, intracranial hematoma, intraventricular hemorrhage, subarachnoid hemorrhage, etc.).
  3. Participant with previous cerebral hemorrhage, brain tumor, brain trauma or other brain diseases.
  4. Taking ACEI antihypertensive drugs regularly and could not stop.
  5. Participant with major surgery or severe trauma in the past 2 weeks.
  6. Poor compliance and cannot fully follow the study protocol.
  7. Pregnancy or lactation.
