Details and patient eligibility

About

This study aims to explore the efficacy and safety of Human Urinary Kallidinogenase for acute ischemic stroke patients receiving intravenous thrombolysis and/or endovascular treatment.

Full description

Within 24 hours after symptom onset, eligible participants will be randomly assigned in a 1:1 ratio to the HUK or placebo group, receiving adjunctive HUK or placebo treatment alongside standard intravenous thrombolysis and/or endovascular treatment. All participants will be recommended to continuously inject drugs or placebo for 10 to 14 days according to length of hospitalization.

  • Intervention group: HUK (0.15 PNA) and sodium chloride injection (100ml), once per day
  • Control group: placebo (0 PNA) and sodium chloride injection (100ml), once per day The total follow-up duration is 90 days.

  3. Having an allergy history of HUK or drugs containing HUK, or other drugs and food.
  4. Having a history of coagulation dysfunction, systemic bleeding, or thrombocytopenia; having hemorrhagic diseases at the time of enrollment, including cerebral hemorrhage, subarachnoid hemorrhage, epidural or subdural hematoma, gingival bleeding, gastrointestinal bleeding, dermal ecchymosis, etc; taking anticoagulants including warfarin, rivaroxaban, etc.; or taking heparin within 48 hours after stroke onset.
  5. Taking angiotensin-converting enzyme inhibitor (ACEI) antihypertensive drugs regularly within one week before enrollment, including captopril, enalapril, benazepril, etc.
  6. Having chronic liver disease or liver dysfunction, with elevated ALT/AST (>3.0×ULN ); or having kidney dysfunction or receiving dialysis, with elevated serum creatinine (>2.0×ULN).

  8. Having contraindications for intravenous thrombolysis or endovascular treatment, including intra-arterial thrombolysis, mechanical thrombectomy, or intravenous rt-PA /TNK-tPA bridging endovascular treatment.
  9. Having lethal diseases with a life expectancy < 3 months.
  10. Being pregnant or lactating; or women of child-bearing age not taking effective contraception, or having no negative pregnancy test record.
  11. Being unable to complete the study due to mental illness, cognitive or emotional disorder, physical condition, geographical factors, etc.
