Could a quick blood thinner before stroke surgery boost recovery?
NCT ID NCT07135089
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether giving the blood-thinning drug tirofiban before a clot-removal procedure helps people recover better after a stroke caused by a blocked artery. About 870 adults with a large-vessel stroke will receive either tirofiban or a placebo before the procedure. The main goal is to see if more people can live independently 90 days later.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tirofiban (a blood-thinning drug given intravenously)
- What this could lead to
- If it works, this could provide a new way to reduce disability after stroke by giving a clot-preventing drug right before the clot-removal procedure.
- What could go wrong
- This is a large phase 3 trial, but it is still testing an unproven approach. The drug may increase bleeding risk, and the benefit may be small or not apply to all stroke patients.

Inclusion Criteria: * 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. Exclusion Criteria: * 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.
