Intra-arterial Recombinant Human Tenecteplase Tissue-type Plasminogen Activator (rhTNK-tPA) Thrombolysis for Acute Medium Vessel Occlusion
Intra-arterial Recombinant Human Tenecteplase Tissue-type Plasminogen Activator (rhTNK-tPA) Thrombolysis for Acute Medium Vessel Occlusion -- A Multicenter, Prospective, Randomized, Open-label, Blinded End-point Trial
Source: ClinicalTrials.gov · Last updated 21 Jan 2026
Brief summary (registry, in English)
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. Recent randomized trials (DISTAL, ESCAPE-MeVO, DISCOUNT) have not demonstrated clinical benefit of endovascular treatment (EVT) for MeVO and have suggested higher risks of symptomatic intracranial hemorrhage and mortality, underscoring the need for safer and more targeted reperfusion strategies. Intra-arterial thrombolysis (IAT) enables localized, high-concentration thrombolytic delivery with minimal mechanical manipulation, which may be advantageous for medium and distal vessels. Recombinant human TNK tissue-type plasminogen activator (rhTNK-tPA), a genetically engineered third-generation thrombolytic agent, has shown favorable pharmacologic properties and clinical safety in AIS, including in intra-arterial use following EVT. However, prospective evidence supporting its direct therapeutic role in MeVO-related AIS remains lacking. This multicenter, prospective, open-label randomized controlled trial with blinded endpoint assessment is designed to evaluate the efficacy and safety of intra-arterial rhTNK-tPA thrombolysis in improving functional outcome in MeVO within 24 hours of symptom onset.
