Overview

A recent pilot study suggests intra-arterial tenecteplase (TNK) during the first pass of endovascular treatment (EVT) seems safe, may increase first-pass reperfusion and good outcome in acute ischemic stroke (AIS) patients with large vessel occlusion (LVO).

The study aimed to determine the efficacy and safety of intra-arterial TNK administration during EVT in AIS-LVO patients.

Eligibility

Inclusion Criteria:

  • Age ≥18 years;
  • Stroke patient with large vessel occlusion (internal carotid artery, M1 or M2 of middle cerebral artery, basilar artery, or intracranial segment of vertebral artery) who meets criteria for endovascular treatment within 24 hours of stroke onset;
  • The modified Rankin Scale (mRS) score before onset ≤ 2;
  • ASPECTS 6 or greater on CT
  • Signed informed consent.

Exclusion Criteria:

  • hemorrhagic stroke;
  • Tandem occlusion;
  • Coagulation disorders, systematic hemorrhagic tendency, thrombocytopenia (<100000/mm3);
  • Severe hepatic or renal dysfunction, increase in ALT or AST (more than 2 times of upper limit of normal value), elevated serum creatinine (more than 1.5 times of upper limit of normal value) or requiring dialysis;
  • Severe uncontrolled hypertension (systolic blood pressure over 200mmHg or diastolic blood pressure over 110 mmHg);
  • Patients with contraindication or allergic to any ingredient of drugs in our study;
  • Pregnancy, or plan to get pregnant or during active lactation;
  • Suspected septic embolus or infective endocarditis
  • The estimated life expectancy is less than 6 months due to other serious diseases;
  • Other conditions unsuitable for this clinical study as assessed by researcher.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
