About this trial

A phase III, multicentre, prospective, randomised, open-label, blinded-endpoint clinical trial will evaluate two thrombolytic agents for the treatment of acute large vessel occlusion stroke within 4.5 hours from symptoms onset: intravenous tenecteplase bridging mechanical thrombectomy vs. intravenous alteplase bridging mechanical thrombectomy.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age is ≥18 years.

AIS symptom onset ≤4.5 hours, onset time refers to the time the patient was last known to be well. (Recommendation time from thrombolysis to puncture within 60 minutes).

Arterial occlusion of the internal carotid artery (ICA), anterior cerebral artery (ACA), posterior cerebral artery (PCA), M1 or M2 segment of the middle cerebral artery (MCA), or basilar artery on computed tomography angiography (CTA) or magnetic resonance angiography (MRA).

Prestroke mRS score ≤2.

Disqualifiers

Patients diagnosed with hemorrhagic stroke (including intraparenchymal hemorrhage, intraventricular hemorrhage, subarachnoid hemorrhage, subdural/extradural hematoma, etc.) or other related conditions identified by CT.

Contraindication to imaging examinations involving contrast agent injection.

Patients presenting with clinical symptoms of coma (NIHSS Score Item 1a = 3).

History of intracranial hemorrhage.
