Acute Ischemic StrokePhase 2/3MeVO-TNK ⅡNCT07302854
Intra-arterial Recombinant Human Tenecteplase Tissue-type Plasminogen Activator (rhTNK-tPA) Thrombolysis for Acute Medium Vessel Occlusion
A Phase 2/3 study testing Intra-arterial Thrombolysis and Standard medical treatment in people with Acute Ischemic Stroke and Medium Vessel Occlusion, run by Xiang Luo at 1 site in China.
Trial summary
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.

About this study
Official title: 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
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.
Read the detailed description
This study is an investigator-initiated, multicenter, prospective, randomized, open-label, blinded-endpoint (PROBE) clinical trial designed to evaluate the efficacy and safety of intra-arterial rhTNK-tPA in improving 90-day functional outcomes in patients with MeVO stroke within 24 hours of symptom onset. The primary outcome is the proportion of patients achieving a modified Rankin Scale (mRS) score of 0-1 at 90 days. Eligible patients will be randomized in a 1:1 ratio to receive either intra-arterial rhTNK-tPA thrombolysis (0.125 mg/kg, Max 12.5mg) plus standard medical therapy or standard medical therapy alone. A total of 382 participants (191 per group) will be enrolled in this trial.

What is being measured
The primary outcome is the main question the study is designed to answer.
Excellent outcome
Rate of modified Rankin scale (mRS) 0-1 at 90±7 days
Measured: 90±7 days
Secondary outcomes (5)
Ordinal distribution of mRS
The shift analysis of mRS at 90±7 days (mRS 5 and 6 merged)
Measured: 90±7 days
Functional independence
Rate of mRS 0-2 at 90±7 days
Measured: 90±7 days
Quality of life (EQ-5D-5L)
The EuroQol 5-Dimension 5-Level questionnaire (EQ-5D-5L) index score at 90±7 days
The EQ-5D-5L is a standardized, preference-based measure of health-related quality of life covering five dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression), each with five severity levels. The EQ-5D-5L index score typically ranges from less than 0 (health states worse than death) to 1.0 (full health), with higher scores indicating better quality of life.
Measured: 90±7 days
Neurologic deficit (NIHSS score) changes
The change of the National Institutes of Health Stroke Scale (NIHSS) score from baseline to 36±12 hours
The NIHSS is a standardized clinical scale used to quantify neurologic impairment in stroke patients. The total score ranges from 0 to 42, with higher scores indicating more severe neurologic deficit. The outcome is defined as the change in NIHSS score from baseline, where a greater negative change reflects greater neurologic improvement.
Measured: 36±12 hours
Infarct core volume change from baseline
Infarct core volume change from baseline at 7±1 days or discharge if earlier
Measured: 7±1 days or discharge if earlier

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Intra-arterial Thrombolysis and Standard medical treatment in people with Acute Ischemic Stroke and Medium Vessel Occlusion, run by Xiang Luo at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 21 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Xiang Luo, PhD, MD (+86-13349893413, flydottjh@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Excellent outcome (time frame: 90±7 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07302854, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Jan 2026.
