This study is no longer in our active list. It may have stopped recruiting or finished. The details below are as of 2026-05-14 and are kept for reference. Check ClinicalTrials.gov for its current status, or see similar studies below.
This study is testing whether a combination of two treatments for a type of stroke caused by a blocked basilar artery works better than using just one of those treatments alone.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are patients diagnosed with acute ischemic stroke caused by basilar artery occlusion who are eligible for both intravenous thrombolysis and endovascular treatment.
✕Probably not a fit
Patients who have contraindications for thrombolysis or those with intracranial hemorrhage will not benefit from this study.

What this trial studies
This clinical trial aims to compare the efficacy and safety of intravenous thrombolysis (IVT) followed by endovascular treatment (EVT) against EVT alone in patients suffering from acute ischemic stroke caused by basilar artery occlusion. The study will be conducted as a multicenter, prospective, open-label, blinded endpoint evaluation, randomized controlled trial. It seeks to address the current lack of direct comparisons between these two treatment strategies, which have shown varying results in previous studies. By enrolling eligible patients within 4.5 hours of symptom onset, the trial will provide valuable insights into the best treatment approach for this severe condition.
Why it matters
Potential benefit: If successful, this study could lead to improved treatment protocols for patients with acute ischemic stroke due to basilar artery occlusion, potentially enhancing recovery and reducing mortality rates.
How similar studies have gone: While previous studies have suggested that IVT followed by EVT may be superior, this trial is novel in its direct comparison of these two treatment strategies in a randomized controlled setting.

Show full inclusion / exclusion criteria
Inclusion criteria: 1. A clinical diagnosis of AIS. 2. Caused by BAO confirmed by CTA, MRA, or DSA. (BAO is defined as the absence of visualization of the basilar artery on CTA, MRA or DSA. Bilateral vertebral artery occlusions or occlusion of a unilateral vertebral artery that is the sole supplier of the basilar artery, even in the presence of patent basilar artery, will be considered de facto BAO.) 3. CT or MRI ruling out intracranial hemorrhage, 4. Eligible for IVT and EVT (within 4.5 hours of symptom onset). (Symptoms onset is defined as point in time the patient was last seen well \[at baseline\] if patients are unable to provide a reliable history or the point in time when symptoms have started if patients can provide a reliable history. Symptoms onset includes diplopia, midline ataxia, visual loss, sensory or motor deficits, and conscious disturbance. Isolated vertigo \[not accompanied by dysarthria, motor weakness, sensory symptoms, double vision, depressed level of consciousness\] is not considered onset of symptoms.) 5. NIHSS score ≥ 6. 6. Age ≥ 18 years. 7. Signed informed consent by the patient or legal representative. Exclusion criteria: 1. mRS score \> 2 before this stroke. 2. Any contraindication to IVT as per the 2019 AHA/ASA guidelines for early management of AIS: 1) Blood pressure \> 185/110 mmHg and cannot be controlled by standard medication, 2) Blood glucose \< 50mg/dL (2.8 mmol/L) or \> 400mg/dL (22.2 mmol/L), 3) Had a cerebral infarction in the previous 6 weeks with residual neurological deficit or signs of recent infarction on neuroimaging, 4) Severe head trauma in the previous 3 months, 5) Major surgery or severe trauma in the previous 2 weeks, 6) Gastrointestinal or urinary bleeding in the previous 3 weeks, 7) previous intracranial hemorrhage, 8) Using anticoagulants and International normalized ratio (INR) \> 1.7, 9) Known platelet count \< 100 × 109/L, 10) treatment with direct thrombin or factor X inhibitors, 11) Heparin treatment in the previous 48 hours with the activated partial thromboplastin time (APTT) exceeding the upper limit of normal. (3) Pregnancy, breastfeeding, or intention to conceive during the study period. (4) Other conditions deemed unsuitable by the investigator.
