Study Details

Study Description

Brief Summary

The purpose of this study is to investigate the safety and efficacy of rhPro-UK (35mg) versus standard medical treatment in acute mild ischemic stroke within 4.5 hours of symptom onset.

Condition or Disease Intervention/Treatment Phase
  • Drug: Recombinant Human Prourokinase for Injection (rhPro-UK)
  • Drug: standard medical treatment
Phase 3

Detailed Description

After being informed about the study and potential risks, patients who meet the eligibility requirements will be randomized to recombinant human Prourokinase for injection (rhPro-UK) or standard medical treatment in a 1:1 ratio. Written informed consent will be needed.

Arms and Interventions

Arm Intervention/Treatment
Experimental: rhPro-UK (35mg)

rhPro-UK: 35 mg (5 mg per vial, 7 vials in total) Dissolve 15mg (3 vials) of rhPro-UK in 10ml of saline and intravenous bolus within 3 minutes, and dissolve the remaining 20mg (4 vials) in 90ml of saline and intravenous drip within 30 minutes. (Note: after adding saline, overturn it gently once to twice, do not shake vigorously, so as to avoid foaming of the rhPro-UK solution and reduce the efficacy).

Drug: Recombinant Human Prourokinase for Injection (rhPro-UK)
15mg of rhPro-UK intravenous bolus within 3 minutes, and the remaining 20mg intravenous drip within 30 minutes.
