Recruiting PHASE2, PHASE3 Acute Ischemic Stroke

New treatment option for Acute Ischemic Stroke

Official title Intra-arterial Recombinant Human Tenecteplase Tissue-type Plasminogen Activator (rhTNK-tPA) Thrombolysis for Acute Medium Vessel Occlusion

ClinicalTrials.gov ID: NCT07302854

What this study is testing

What is Standard medical treatment?

Standard medical treatment is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for acute ischemic stroke.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
Medium vessel occlusion (MeVO) accounts for 20-45% of acute ischemic stroke (AIS). Although patients with MeVO often present with relatively low NIHSS scores, up to one-third remain functionally dependent at follow-up despite receiving standard medical therapy, including intravenous thrombolysis.
  • Phase 3: a large, late-stage study
  • Which group you join is decided by chance.
