A Randomized Controlled Trial of TNK-tPA Versus Standard of Care for Minor Ischemic Stroke With Proven Occlusion

This trial will enroll patients that have been diagnosed with a transient ischemic attack (TIA) or minor stroke that has occurred within the past 12 hours. Anyone diagnosed with a minor stroke faces the possibility of long-term disability and even death, regardless of treatment. Stroke symptoms such as weakness, difficulty speaking and paralysis may improve or worsen over the hours or days immediately following a stroke. TEMPO-2 is a minor stroke trial for patients presenting within 12 hours of their symptom onset. Patients will be randomized to TNK-tPA or standard of care. In the intervention group TNK-tPA is given as a single, intravenous bolus (0.25mg/Kg) immediately upon randomization. Maximum dose 50mg. The control group will receive antiplatelet agent(s) as decided by the treating physician. Antiplatelet agent(s) choice will be at the treating physician\'s discretion. TEMPO-2 Coordinating Centre is located in Calgary, AB, Canada. There will be approximately 50 sites participating worldwide. Dr. Shelagh Coutts is the Principal Investigator.
