💬In plain words
What the trial is, and whether it could suit you
This randomized controlled trial aims to evaluate whether adjunctive tirofiban therapy combined with endovascular treatment (EVT) improves neurological outcomes in patients with acute large vessel occlusion due to large-artery atherosclerosis. Patients will be randomized to receive either tirofiban or matching placebo after EVT. The primary efficacy endpoint is the proportion of patients achieving functional independence (modified Rankin Scale 0-2) at 90±7 days, while the safety endpoint is the probability of symptomatic intracranial hemorrhagewithin 48 hours after randomization.
