A Study to Evaluate the Safety and Efficacy of LT3001 Drug Product in Subjects AIS Undergoing EVT

Exclusion Criteria

• •1. Subject has been treated or intent to treat with intravenous thrombolytic during the current AIS, e.g., recombinant tissue-type plasminogen activator (rtPA).
• •2. Subject has been treated with EVT before investigational product administration during the current AIS.
• •3. Subject has a pre-stroke disability that requires help for activities of daily living (mRS ≥2).
• •4. Subject has large ischemic core volume \>70 mL or Alberta Stroke Program Early CT Score (ASPECTS) of ≤5.
• •5. Subject has symptoms of suspected subarachnoid hemorrhage, even if CT is normal.
• •6. Subject has imaging evidence of acute intracranial hemorrhage, intracranial tumor (except small meningioma), arteriovenous malformations, other central nervous system lesions that could increase the risk of bleeding, or aneurysm requiring treatment.
• •7. Subject has significant mass effect with midline shift.
• •8. Subject has intracranial stent implanted in the same vascular territory that precludes the safe deployment/removal of the neurothrombectomy device.
• •9. Subject has pre-existing medical, neurological, or psychiatric disease that would confound the neurological or functional evaluations, e.g., seizures at onset of the current AIS, dementia.
• •10. Subject has current uncontrolled hypertension despite treatment: systolic blood pressure \>185 mmHg or diastolic blood pressure \>110 mmHg before dosing at Screening (Visit 1).
• •11. Subject has hemorrhagic diathesis, coagulation factor deficiency or recent oral anticoagulant therapy with International Normalized Ratio (INR) \>1.7 or activated partial thromboplastin time (aPTT) \>3 times of upper limit of normal range at Screening (Visit 1).
• •12. Subject has received one of the new oral anticoagulants within 48 hours before treatment, e.g., dabigatran, apixaban.
• •13. Subject has platelet count \<100,000/mm 3 at Screening (Visit 1).
• •14. Subject has hemoglobin \<7 mmol/L at Screening (Visit 1).
• •15. Subject has abnormal sodium concentration \<130 mmol/L and/or potassium concentration \<3 mEq/L or \>6 mEq/L at Screening (Visit 1).
• •16. Subject has blood glucose concentration \<50 mg/dL or \>400 mg/dL at Screening (Visit 1).
• •17. Subject has severe hepatic, renal, and/or active infectious disease at Screening (Visit 1).
• •18. Subject is lactating, pregnant (pregnancy test required for all female subjects of childbearing potential), or planning to become pregnant during the study.
• •19. Subject has had prior AIS, myocardial infarction, or serious head trauma within 90 days of Screening (Visit 1).
• •20. Subject has history of ICH within 90 days of Screening (Visit 1).
• •21. Subject has had any major surgery within 90 days of Screening (Visit 1), e.g., intracranial or intraspinal surgery, coronary artery bypass graft, obstetrical delivery, organ biopsy.
• •22. Subject has had a bleeding event within 21 days of Screening (Visit 1), e.g., gastrointestinal or hemorrhage.
• •23. Subject has puncture of noncompressible vessels within 7 days of Screening (Visit 1).
• •24. Subject has participated in another investigational study and received investigational product within 30 days of Screening (Visit 1) or 5 half-lives (whichever is longer).
• •25. In the opinion of the Investigator, the subject is precluded from EVT procedure, or a significant hazard is posed to the subject if EVT procedure is performed.
• •26. In the opinion of the Investigator, the subject has serious, advanced, or terminal illness that will prevent improvement or follow-up visits.
• •27. In the opinion of the Investigator, the subject is not appropriate for the study for any other reason.
