Endovascular Treatment With or Without Preceding Intravenous Tenecteplase (TNK) in Patients With Late-window acUte Ischemic Stroke Due to Middle Cerebral Artery Occlusion: a Multi-center, Prospective, Randomized, Open-label, Blinded Endpoint (PROBE), Phase 3 Trial
In Brief
A Phase 3 clinical trial evaluating Tenecteplase and direct EVT for Ischemic Stroke, Acute and 2 related conditions. Completed, enrolled 391 participants across 21 sites.
Detailed Summary
The purpose of this study is to investigate the safety and efficacy of endovascular treatment with or without preceding intravenous Tenecteplase in patients with late-window (4.5-24 hours of symptom onset) acute ischemic stroke due to middle cerebral artery (MCA) M1 or proximal M2 occlusion.
Study Details
Timeline
Interventions
Tenecteplase (0.25 mg/kg, maximum dose 25mg) is given as a single, intravenous bolus (injection over 5 to 10 seconds) immediately upon randomization. EVT should be performed as soon as possible after Tenecteplase administration.
During the study period, NMPA-approved stents are permitted. EVT included thrombectomy with stent retrievers, thromboaspiration, intraarterial thrombolysis, balloon angioplasty, stenting, or a combination of these approaches at the discretion of the interventional team.
