Plain-language summary
IAT-MeVO is an international, multicenter, prospective, randomised, open-label, blinded end-point assessed (PROBE) trial, to evaluate the efficacy and safety of endovascular therapy (EVT) \[intra-arterial thrombolysis (IAT)-based\] versus best medical management (BMT) in patients with acute ischemic stroke (AIS) due to medium vessel occlusion (MeVO) who are ineligible for intravenous thrombolysis (IV) within 24 h of onset.

Inclusion criteria
. Age ≥ 18 y;
. Diagnosed as acute ischemic stroke;
. Isolated medium distal vessel occlusion (i.e. an occlusion of the M2, the M3/M4 segment of the MCA, the A1/ A2/A3 segment of the ACA or the P1/P2/P3 segment of the PCA) confirmed by CT or MR Angiography;
. Time from onset (or last-seen-well) to randomization \< 24h;
. Has not received intravenous thrombolysis and is considered unsuitable for it based on the treating clinician's assessment.
. NIHSS ≥ 5, or NIHSS ≤ 4 with disabling deficit (e.g. severe aphasia, hemianopia, hemiplegia/loss of function in one side) or fluctuating symptoms at the time of randomization;
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.
. For patients within 6 h of onset: No visually apparent hypodensity is observed on non-contrast CT compared with the contralateral white matter, or no hyperintensity is seen on fluid-attenuated inversion recovery (FLAIR) imaging; For patients presenting 6-24 h after onset: A perfusion imaging-based ischemic core mismatch ratio \>1.2 and an infarct core volume \<50 mL are required;
. Pre-stroke mRS ≤ 1；
Exclusion criteria
. Any evidence of intracranial hemorrhage on qualifying imaging;
. Suspected cerebral vasculitis, septic embolism, or infective endocarditis as the cause of vessel occlusion;
. Suspected arterial dissection;
. Clinical assessment of conditions unsuitable for interventional therapy (e.g., severe contrast agent allergy or absolute contraindications to iodine contrast agent; severe renal insufficiency, glomerular filtration rate \< 30ml/min or serum creatinine \> 220μmol/L (2.5 mg/dl));
. Unsuitable for arterial thrombolytic therapy (e.g., known history of hereditary or acquired hemorrhagic disease and/or platelet count \<50×109/L; abnormal coagulation function (INR\>1.7); oral anticoagulants were taken within 24 - 48 hours before onset within APTT \> 3 times normal; recent medical history or clinical manifestations of brain tumors other than meningiomas);
. Any terminal disease with life expectancy \<1 year;
