Ischemic Stroke, Acute Clinical Trial
Official title:
Tirofiban for Patients With intraCranial Artery Stenosis and High-risk Acute Non-disabling Cerebrovascular Events(CHANCE-4）
The CHANCE-4 study is a multicenter, double-blind, double-simulation, randomized controlled study. In patients at high-risk for mild ischemic stroke or transient ischemic attack with symptomatic intracranial artery stenosis within 24 hours of onset, we will examine whether treatment with tirofiban for 48 hours reduce the risk of ischemic stroke recurrence within 90 days compared with placebo.

| Eligibility | Inclusion Criteria: - 1.40 years or older than 40 years. 2.Acute cerebral ischemic event due to: Acute mild ischemic stroke (NIHSS=5 at the time of randomization) or TIA with moderate-to-high risk of stroke (ABCD2 score = 6 at the time of randomization). 3.Symptomatic intracranial artery stenosis (symptomatic intracranial artery stenosis is defined as =50% stenosis of the supplying artery of the infarct lesion). 4.Can be treated with study drug within 24 hours of symptoms onset*(*Symptom onset is defined by the "last seen normal" principle). 5.Informed consent signed. Exclusion Criteria: 1. Diagnosis of bleeding or other pathological brain disorders, such as vascular malformations, tumors, abscesses, or other common non-ischemic brain diseases (such as multiple sclerosis) based on baseline head CT or MRI. 2. Evaluation of intracranial arterial stenosis could not be completed before randomization. 3. Isolated or pure sensory symptoms (e.g., numbness), isolated visual changes, or isolated dizziness/vertigo without evidence of acute infarction on baseline head CT or MRI. 4. Iatrogenic causes (angioplasty or surgery) of stroke or TIA. 5. Pre-onset mRS Score >2(According to the assessment of patients' pre-onset history, patients with mRS>2 pre-onset cannot be enrolled). 6. Contraindications to tirofiban. 6.1 Known allergy history. 6.2 Severe renal (creatinine exceeding 1.5 times of the upper limit of normal range) or hepatic (ALT or AST > twice the upper limit of normal range) insufficiency. 6.3 Severe cardiac failure (NYHA level: III to IV). 6.4 History of hemostatic disorder or systemic bleeding. 6.5 History of thrombocytopenia or neutropenia. 6.6 History of drug-induced hematologic disorder or hepatic dysfunction. 6.7 Low white blood cell (<2×109/L) or platelet count (<100×109/L). 7. Tirofiban has been used since the onset of the disease. 8. Hematocrit (HCT) <30%. 9. Clear indication for anticoagulation (presumed cardiac source of embolus, e.g., atrial fibrillation, prosthetic cardiac valves known or suspected endocarditis). 10. History of intracranial hemorrhage or amyloid angiopathy. 11. History of aneurysm (including intracranial aneurysm and peripheral aneurysm). 12. History of asthma or COPD (chronic obstructive pulmonary disease). 13. High risk chronic arrhythmias such as diseased sinus syndrome, second or third degree atrioventricular block, bradycardia related syncope without pacemaker. 14. Surgical or endovascular treatment is expected in the next three months. 15. Other planned surgical procedures or interventional treatments may require discontinuation of antiplatelet medication. 16. Severe non-cardiovascular comorbidity with life expectancy < 3 months. 17. Inability to understand and/or follow research procedures due to mental, cognitive, or emotional disorders. 18. Used heparin or oral anticoagulants within 10 days before enrollment. 19. Patients who had undergone intravenous or arterial thrombolysis or mechanical thrombolysis within 24 hours before enrollment. 20. Large cerebral infarction (infarction area exceeding 1/2 responsible artery supply area). 21. Gastrointestinal bleed within 3 months or major surgery within 30 days. 22. Diagnosis or suspicious diagnosis of acute coronary syndrome. 23. Participation in another clinical study with an experimental product during the last 30 days. 24. Currently receiving an experimental drug or device. 25. Women of childbearing age, pregnant or lactating women who refuse to use effective contraception after a negative pregnancy test. |
