- Brief Summary
Stroke is the second leading cause of death worldwide, killing nearly 7 million people every year. Acute ischemic stroke is caused by focal cerebral hypoperfusion, usually due to embolism or atherosclerotic disease . Ischemic strokes account for 60-70% of all strokes worldwide and are severely debilitating, drawing considerable attention due to their high prevalence.The majority of studies comparing the efficacy and safety of teneplase and alteplase are predominantly randomized controlled trials with limited representation from real-world studies.The aim of this study is to compare the safety, efficacy and economic benefits of recombinant human TNK tissue plasminogen activator (tenecteplase, rhTNK-tPA, TNK) and recombinant tissue plasminogen activator (alteplase, rtPA) in clinical practice. This study aimed to establish a foundation for refining intravenous thrombolytic therapy tailored to various patient profiles and to guide clinicians in selecting the most suitable thrombolytic treatment options.
- Detailed Description
TRANSIT is a prospective, multicenter, open-label real world study.The purpose of this study was to compare the safety, efficacy and economic benefits of recombinant human TNK tissue plasminogen activator (tenecteplase, rhTNK-tPA, TNK) and recombinant tissue plasminogen activator (alteplase, rtPA) in practical clinical applications. To provide the basis for optimizing the intravenous thrombolysis program for different types of patients, and to provide a reference for clinicians to choose the appropriate thrombolytic therapy program.
6000 individuals who met the indications for intravenous thrombolysis and signed informed consent were included.The enrolled patients received treatment with tenecteplase (rhTNK-tPA) at a dosage of 0.25 mg/kg, up to a maximum of 25 mg, or alteplase (rtPA) at a dosage of 0.9 mg/kg, up to a maximum of 90 mg, based on their clinical condition and the preferences expressed by the patients and their families. Assessments were conducted at baseline, as well as at 24, 36, and 72 hours post-thrombolysis. Follow-up evaluations were performed on day 7 (or prior to discharge) and day 90.The primary efficacy endpoint was the proportion of excellent functional outcomes at 90±7 days (modified Rankin Scale score, mRS 0 or 1).The primary safety outcome was the proportion of sICH within 36 h (as defined by The European Cooperative Acute Stroke Study III criteria).The economic endpoint included the total costs of the first hospitalization and the days at home within 90±7 days.

Group Intervention Description TNK group Tenecteplase The enrolled patients received treatment with tenecteplase (rhTNK-tPA) at a dosage of 0.25 mg/kg, up to a maximum of 25 mg. rtPA group Alteplase The enrolled patients received treatment with alteplase (rtPA) at a dosage of 0.9 mg/kg, up to a maximum of 90 mg.
- Primary Outcome Measures
Name Time Method mRS 90±7 days after enrollment The primary efficacy endpoint is the proportion of excellent functional outcome at 90±7 days (modified Rankin Scale score, mRS 0 or 1).The modified Rankin Scale is commonly used to measure neurological recovery after stroke on a scale of 0-6, with higher scores associated with worse outcomes .
- Secondary Outcome Measures
Name Time Method NIHSS score 7±1 days after enrollment Incidence of Neurological deterioration at 7±1 days (NIHSS score increased by ≥2 points and cerebral hemorrhage was excluded)
proportion of sICH 36h after treatment The safety outcome is the proportion of sICH within 36 hours (as defined by The European Cooperative Acute Stroke Study III criteria）
rate of death 90 days after enrollment Secondary safety end points related to Rate of death from any cause within and Rate of systemic bleeding within 90 days.
mRS 90±7 days after enrollment The proportion of favourable functional outcome at 90±7 days (mRS 0-2)
stroke recurrence 90±7 days after enrollment Incidence of stroke recurrence and other vascular events at 90±7 days.
