China516 participantsStarted 2023-11-09
Plain-language summary
Branch atheromatous disease (BAD)-related stroke, characterized by subcortical single infarcts without severe stenosis of the large artery, but with a clear atherosclerotic mechanism, is now regarded as a separate stroke type. BAD is associated with early neurological deterioration and poor prognosis, but is lack of effective therapy. The goal of this randomized controlled trial is to test the efficacy and safety of intravenous tirofiban in patients with acute ischemic stroke caused by branch atheromatous disease. The main question it aims to answer is: Compared with standard antiplatelet therapy based on current stroke guideline, whether tirofiban used in acute phase of BAD could improve the proportion of excellent functional outcome (modified Rankin Scale: 0-1) at 90 days. Researcher will also compare the rate of major bleeding between treatment and control groups.

Inclusion criteria
. Age: 18-75 years old
. Acute ischemic stroke
. Time from onset to randomization ≤48h; if onset time is unknown, time from last known well to randomization ≤48h
. Meet the following BAD Diagnostic Imaging Criteria
.1. DWI infarcts: single (isolated) deep (subcortical) infarcts;
.2. The culprit arteries are either Lenticulostriate artery (LSA) or Paramedian pontine artery (PPA), and the infarct lesion on DWI conforms to one of the following characteristics (A/B): A. LSA: 1) "Comma-like" infarct lesions with "Fan-shaped" extension from bottom to top in the coronal plane; or 2) ≥ 3 layers (layer thickness 5-7 mm) on axial DWI brain images; B. PPA: The infarct lesion extends from the deep pons to the ventral pons on the axial DWI brain images;
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
.3. No more than 50% stenosis on the parent artery of the criminal artery (i.e. corresponding basilar or middle cerebral artery) (Confirmed by magnetic resonance angiography \[MRA\] or computed tomography angiography \[CTA\] or digital substraction angiography \[DSA\]).
. Singed informed consent by the patient or legally authorized representatives.
Exclusion criteria

. Presence of ≥50% stenosis in extracranial artery in tandem relationship ipsilateral to the lesion;
. Cardiogenic embolism: atrial fibrillation, myocardial infarction, heart valve disease, dilated cardiomyopathy, infective endocarditis, atrioventricular block disease, heart rate less than 50 beats per minute
. Have received or plan to receive endovascular therapy or thrombolysis after onset;
. Stroke of other clear causes, e.g., moyamoya disease, arterial dissection, vasculitis, etc.
. modified Rankin Scale ≥2 before onset
. Use of tirofiban within 1 week before or after onset
