Active Comparator: Control
Usual care with alteplase 0.9 mg/kg in 60 minutes
Other Name: Actilyse
- Any intracranial hemorrhage according to the Heidelberg Bleeding Classification on MRI [ Time Frame: 24-48 hours post-treatment ]
- Score on the National Institutes of Health Stroke Scale (NIHSS) [ Time Frame: at 24 hours and 5-7 days post-treatment ]The NIHSS measures neurological deficit, ranging from 0 to 42, with higher scores indicating more severe neurological deficit.
- Score on the modified Rankin Scale (mRS) [ Time Frame: at 30 days ]The mRS is an ordinal scale ranging from 0 (no symptoms) to 6 (death) measuring the degree of disability or dependence in everyday life.
- Infarct volume on MRI [ Time Frame: at 24-48 hours ]
- Change (pre-treatment vs. post-treatment) in abnormal perfusion volume based on TTP/MTT maps measured with CT perfusion at baseline and MRI [ Time Frame: at 24-48 hours post treatment. ]
- Secondary blood biomarkers of thrombolysis: d-dimer levels and fibrinogen levels. [ Time Frame: 1 hour post-treatment, after 3 hours, and after 24 hours post-treatment, ]
- Symptomatic intracranial hemorrhage (sICH) according to the Heidelberg Bleeding Classification [ Time Frame: within 30 days ]sICH is defined as any intracranial hemorrhage followed by a neurological deterioration that can be attributed to that hemorrhage, defined as an increase of >= 4 points on the NIHSS or >= 2 points on a specific NIHSS item.
- Death from any cause [ Time Frame: Within 30 days ]
- Major extracranial hemorrhage according to the ISTH criteria [ Time Frame: within 24 hours of study drug administration ]
