About this trial

This is an interventional treatment trial for Acute Ischemic Stroke focused on measuring Sofadil; Acute ischemic stroke

Inclusion Criteria:

  • The target population is 35-75 years old, regardless of gender;
  • within 6h of onset, ischemic stroke of the internal carotid artery system;
  • Neurological deficits, including limb weakness, with acute brain injury (NIHSS score) (4-22 points), or NIHSS item 5 upper limb or 6 lower limb score ≥2 points;
  • Be able to initiate study treatment within 6 hours of onset of symptoms or within 6 hours of last appearing normal (6 hours after sleep in subjects with ischemic stroke who developed during sleep) and complete post-onset CT examination prior to study treatment;

  • Patients with primary liver and kidney diseases, AST or ALT twice as high as the normal upper limit, serum creatinine >2.0 mg/dL or >176.8 mol/L;
  • Where the INR is greater than 1.7 or where an oral anticoagulant is currently used, except aspirin, clopidogrel, subcutaneous heparin or Wartamine;
  • Patients with bleeding tendency diseases (such as hemophilia), and partial thromboplastin time (PTT) is more than 3 times of the normal upper limit;

5. Study Description

Brief Summary
To evaluate the efficacy and safety of sofadil injection in the treatment of acute ischemic stroke
Detailed Description
The limited therapeutic time window for neuroprotection has prevented all clinical trials using NMDA receptor antagonists in subjects with ischemic stroke from showing efficacy. In animal models of ischemic stroke, antioxidants showed a longer neuroprotective time window than NMDA receptor antagonists, and also showed therapeutic potential in clinical trials in subjects with ischemic stroke. Sophadil showed good neuroprotective effects against NMDA and free-radical mediated cell death, NR2B-selectivity, moderate NMDA receptor antagonism, and effective cellular osmotic antioxidant activity even at nanoscale molarity. Non-clinical and phase I human clinical studies have shown that Sofadil is helpful in treating ischemic stroke subjects with better efficacy and therapeutic time windows. So we designed the clinical trial to evaluate the efficacy and safety of sofadil injection in the treatment of acute ischemic stroke
