Early Use of Tirofiban After Tenecteplase Treatment in Adults with Acute Ischemic Stroke

What this Trial Is About

Researchers are studying the safety and effectiveness of early use of tirofiban in patients who have acute ischemic stroke and are treated with tenecteplase. This study is exploring whether adding tirofiban soon after tenecteplase can reduce the risk of blood clot re-blockage in the brain, which happens in some patients after initial treatment. The study is a phase 3 trial aiming to improve stroke outcomes by preventing this reocclusion. Participants first receive tenecteplase intravenously for stroke treatment. Those who meet the study criteria are then randomly assigned to receive either tirofiban or a placebo. Tirofiban or placebo is given intravenously starting as soon as possible after randomization, initially as a higher dose for 30 minutes, followed by a continuous lower dose infusion for nearly 48 hours. After 24 hours, patients receive aspirin andor clopidogrel or their placebos, then after 44 hours, antiplatelet therapy with aspirin andor clopidogrel continues until the 90-day follow-up. During the study, participants undergo assessments including neurological exams and monitoring for bleeding or other adverse events. The main outcome measured is excellent functional recovery 90 days after randomization. Other outcomes include disability levels, neurological improvement, quality of life, bleeding events, and mortality. Safety and serious adverse events are tracked through the 90-day period to evaluate treatment effects and risks.
