AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with a sudden stroke caused by a blocked large brain artery, probably from artery hardening. It tests tirofiban given by vein before the clot-removal procedure.
- Age
- 18 years or older
- Sex
- All sexes can join.
- Disease stage
- Stroke with a blocked large artery at the front of the brain, seen on CT or MR angiography. Treatment can start within 12 hours of first symptoms. Artery hardening is strongly suspected as the cause. NIHSS score of 6 or more. ASPECTS score of 6 or more on CT. Before the stroke, mRS score of 2 or less.
- Earlier treatment
- People who took two blood-thinning pills together (dual antiplatelet drugs), DOACs, warfarin or other drugs that raise bleeding risk in the last week cannot join.
Main reasons for not taking part
- History of atrial fibrillation or atrial flutter, or seen on the ECG
- Bleeding in the brain, or a bleeding history within one month
- Brain aneurysm or malformation, twisted arteries that block the procedure, or a brain tumour pressing on the brain
- Severe uncontrolled high blood pressure (over 200 mmHg systolic or over 110 mmHg diastolic)
- Pregnancy or breastfeeding

Improving Neuroprotective Strategy for Ischemic Stroke Before Endovascular Thrombectomy by Intravenous Tirofiban (INSIST-IT2): a Prospective, Randomized, Double Blinded, Multi-center Study
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.
Inclusion: 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: 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; 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); Severe renal insufficiency and advanced disease with an expected life expectancy of less than 6 months; Allergy to drugs or contrast agents; Other conditions that the researcher deems unsuitable for participation in this study; Deficiency of anticoagulant factors or international normalized ratio (INR) > 1.7, platelet count < 90×10⁹/L; Intracranial aneurysms or malformations, tortuous arteries that hinder thrombectomy, and space-occupying effect brain tumors; Pregnancy or lactation; Participating in other clinical trials.
