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 stroke in the back part of the brain who reach care 4.5 to 24 hours after it began. It tests tenecteplase given into a vein.
- Age
- 18 to 100 years
- Sex
- All sexes can join.
- Disease stage
- Acute stroke in the back part of the brain (posterior circulation), confirmed by MRI, or a narrowed or blocked large artery there, or reduced blood flow there on perfusion imaging. Started 4.5 to 24 hours ago. NIHSS score above 3. PC-ASPECTS 7 or higher. Before the stroke, mRS 1 or lower.
- Earlier treatment
- People who plan to have thrombectomy, angioplasty or stenting within 3 months cannot join. No anticoagulant use in the recent past: low-molecular-weight heparin within 24 hours, direct oral anticoagulants within 48 hours, or warfarin with INR above 1.7 or PT above 15 s.
Main reasons for not taking part
- Cannot take tenecteplase or its components
- History of bleeding in the brain
- Stroke, heart attack, severe head injury or brain or spine surgery in the last 3 months
- Uncontrolled blood pressure (above 180 systolic or above 110 diastolic) or uncontrolled very low or very high blood sugar
- Pregnant or breastfeeding, or expected to live less than three months

Efficacy and Safety of Tenecteplase Intravenous Thrombolysis in Acute Posterior Circulation Ischemic Stroke Within 4.5-24 Hours After Onset: A Multicenter, Prospective, Randomized, Open-Label, Blinded Endpoint Trial
This study aims to evaluate the efficacy and safety of tenecteplase (TNK) intravenous thrombolysis within the extended time window (4.5 to 24 hours) in patients with acute posterior circulation ischemic stroke.
Inclusion: Age ≥18 years; Meeting at least one of the following criteria: acute posterior circulation ischemic stroke confirmed by MRI; symptomatic stenosis or occlusion of a posterior circulation large vessel on vascular imaging (CTA/MRA/DSA); perfusion imaging demonstrating clinically relevant hypoperfusion in the posterior circulation territory; Onset time between 4.5-24 hours (for wake-up stroke or unwitnessed stroke, onset time is defined as the midpoint between last known well and symptom detection); NIHSS score>3; PC-ASPECTS ≥7 (if discrepancy exists between DWI and CT findings, CT assessment takes precedence); Pre-stroke mRS ≤1; Signed informed consent by the patient or legally authorized representative.
Exclusion: Planing to receive endovascular therapy with thrombectomy, angioplasty or stenting whin 3 months; History of intracranial hemorrhage; Stroke, myocardial infarction, severe traumatic brain injury, or intracranial/spinal surgery within the preceding 3 months; Active internal bleeding, major surgery, trauma, gastrointestinal/urinary tract bleeding within 3 weeks; Uncontrolled hypertension (systolic BP >180 mmHg or diastolic BP >110 mmHg unresponsive to antihypertensive therapy); Clinically significant bleeding or coagulopathy, including: Warfarin use with INR >1.7 or PT >15 s; Low-molecular-weight heparin within 24 hours; Direct oral anticoagulants within 48 hours; Laboratory abnormalities (e.g., APTT >40 s); Platelet dysfunction or platelet count <100×10⁹/L; Uncontrolled hypoglycemia/hyperglycemia (<50 mg/dL [2.8 mmol/L] or >400 mg/dL [22.2 mmol/L]); Contraindication to tenecteplase or its components; Acute anterior circulation infarction confirmed by MRI, anterior circulation large vessel occlusion on vascular imaging (CTA/MRA/DSA), or anterior circulation hypoperfusion on perfusion imaging; Intracranial tumor, arteriovenous malformation (AVM), or giant aneurysm; Non-compressible arterial puncture within 1 week; Suspected aortic dissection; Pregnancy or lactation; A life expectancy of less than three months; Participation in other clinical trials within 3 months or ongoing trial enrollment; Inability to follow up (e.g., no fixed residence, overseas patients); Patient deemed unsuitable for the trial by site investigator.
