Improving Neuroprotective Strategy for Ischemic Stroke Before Endovascular Thrombectomy by Intravenous Tirofiban

Recruiting now · Phase 3 · Has a placebo group

Conditions studied: Stroke, Ischemic

In brief

It remains uncertain whether intravenous tirofiban administered before endovascular thrombectomy could improve disability severity for patients with LVO due to intracranial atherosclerosis.The current study aimed to assess the efficacy and safety of administering intravenous tirofiban before endovascular thrombectomy for improving clinical outcomes in patients with anterior circulation LVO due to intracranial atherosclerosis.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age ≥ 18 years;
• Anterior circulation large vessel occlusion (the internal carotid artery or the first or second segment of the middle cerebral artery) confirmed by computed tomography angiography (CTA) or magnetic resonance angiography (MRA);
• Eligible for endovascular treatment within 12 hours of symptom onset;
• Based on the patient's medical history, clinical presentation, and imaging findings, large artery atherosclerosis is highly suspected as the underlying etiology;
• Baseline National Institute of Health Stroke Scale (NIHSS) ≥ 6;
• Baseline ASPECTS ≥ 6 on CT;
• A pre-stroke modified Rankin Scale (mRS) score of ≤2;
• Signed informed consent by patient or their legally authorized representative.

You may not qualify if…

• History of atrial fibrillation or atrial flutter, or 12-lead Electrocardiogram before randomization and after admission showing atrial flutter or atrial fibrillation;
• Hemorrhagic stroke: cerebral hemorrhage, subarachnoid hemorrhage, or a history of bleeding within one month;
• Intracranial aneurysms or malformations, tortuous arteries that hinder thrombectomy, and space-occupying effect brain tumors;
• The following drugs are taken within one week: dual antiplatelet drugs, direct oral anticoagulants (DOACs), warfarin and other drugs that increase the risk of bleeding;
• Severe uncontrolled hypertension (systolic blood pressure over 200mmHg or diastolic blood pressure over 110 mmHg);
• Deficiency of anticoagulant factors or international normalized ratio (INR) > 1.7, platelet count < 90×10⁹/L;;
• Severe renal insufficiency and advanced disease with an expected life expectancy of less than 6 months;
• Pregnancy or lactation;
• Allergy to drugs or contrast agents;
• Participating in other clinical trials;
• Other conditions that the researcher deems unsuitable for participation in this study.
