Comparing two treatments for acute ischemic stroke using a mobile stroke unit

Intravenous Tenecteplase Versus Alteplase for Acute Ischemic Stroke Treatment on Mobile Stroke Units, a Prospective Multicenter Randomized Controlled Trial

PHASE4 · Mahidol University · NCT06498323

This study is testing if a new stroke treatment called tenecteplase works better than the standard treatment, alteplase, for people having an acute ischemic stroke.

What this trial studies

This clinical trial investigates the effectiveness of intravenous tenecteplase compared to the standard treatment of intravenous alteplase for patients experiencing acute ischemic stroke. The study is conducted in a multicenter format, utilizing mobile stroke units to provide timely treatment within 4.5 hours of symptom onset. Participants will be monitored for safety and efficacy outcomes to determine if tenecteplase offers advantages over alteplase in this acute setting. The trial aims to provide insights into optimizing thrombolytic therapy for stroke patients.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old who have been diagnosed with acute ischemic stroke within 4.5 hours of symptom onset and have no contraindications for thrombolytic therapy.

Not a fit: Patients who have experienced stroke symptoms for more than 4.5 hours or have contraindications for thrombolytic drugs will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment options for acute ischemic stroke, potentially enhancing recovery and reducing disabilities.

How similar studies have performed: Previous studies have shown that tenecteplase is comparable in efficacy and safety to alteplase, indicating potential for success in this novel application.
