Spoon Feed
Tenecteplase, at a dose of 0.4 mg/kg, is not safe for patients with moderate to severe ischemic stroke.

Does NOAC Use Preclude tPA for Acute Stroke?
Spoon Feed
There was no significant difference in intracranial hemorrhage, serious systemic hemorrhage, or inpatient mortality for patients who used non-vitamin K oral anticoagulants in the seven days prior to receiving alteplase for acute ischemic stroke.

CHOICE RCT – Post-Thrombectomy tPA for Stroke
Among patients with acute ischemic stroke with large vessel occlusion that have been successfully reperfused with thrombectomy, the use of post-thrombectomy adjunctive intra-arterial alteplase results in greater likelihood of excellent neurologic outcome at 90 days - modified-Rankin score 0 or 1 - when compared with placebo.

Early Endovascular Therapy for Basilar Artery Occlusion
Time from symptom onset of a basilar artery occlusion (BAO) to endovascular therapy (EVT) of less than 6 hours compared to greater than 6 hours (up to 24 hours) was associated with lower odds of in-hospital mortality, disability, symptomatic intracranial hemorrhage, and higher odds of ambulation at discharge, discharge home and reperfusion.
