Safety of Intravenous Thrombolysis for Wake-up Stroke "Wake-Up Stroke"


Phase 2 Results

Trial Description

The purpose is to demonstrate the safety of intravenous tissue plasminogen activator (IV t-PA) in ischemic stroke patients who present to the emergency department (ED) after awakening with the symptoms of suspected ischemic stroke.

Detailed Description

This is an open label, multi-center, safety study of acute treatment with IV alteplase in ischemic stroke patients who wake-up with their symptoms. The primary outcome of this study is the frequency of symptomatic hemorrhagic transformation evident within 24 hours of treatment with IV t-PA. Clinical improvement defined as a decrease in the National Institutes of Health Stroke Scale (NIHSS) score at 24 hours, 3 days and 90 days and modified Rankin Scale (mRS) score at 3 and 90 days. For patients that have computed tomographic angiogram (CTA) and computed tomographic perfusion (CTP), the incidence of large vessel occlusion will be quantified.



  • Alteplase (iv t-PA) Drug
    Other Names: Activase®; Alteplase; tissue plasminogen activator; t-PA
    Intervention Desc: 0.9 mg/kg (maximum of 90 mg) IV t-PA will be administered with 10% bolus given over 1 minute, the rest given as an infusion over the remaining hour.
