Safety and Efficacy of Treatment With Early Antiplatelet Administration After Intravenous Thrombolysis for Acute Ischemic Stroke (TREND-IVT): A Multicenter, Randomized, Placebo-controlled, Clinical Trial
Stroke is the second leading cause of death worldwide, and ischemic stroke is the most frequent type. Intravenous thrombolysis with recombinant tissue plasminogen activator within 4.5 hours of symptom onset is the most effective therapy for patients with acute ischemic stroke. However, ischemic stroke progression and early reocclusion are not an uncommon phenomenon in patients after intravenous thrombolysis, resulting in neurological deterioration, which is associated with unfavorable functional outcomes. The underlying mechanism mainly involves the augmented platelet activation, triggered by the activated coagulation cascade during thrombolysis, which peaks within 2 hours of initiating rt-PA administration. Therefore, early antiplatelet therapy following intravenous thrombolysis represents a promising therapeutic approach to prevent neurological deterioration and improve the functional outcome of patients treated with intravenous thrombolysis. Currently, guidelines recommend initiating antiplatelet therapy 24 hours after intravenous thrombolysis due to the potential risk of increased bleeding. The safety and efficacy of early antiplatelet treatment following intravenous thrombolysis in patients with acute ischemic stroke remain clear. The study aims to test the hypothesis that in patients with acute ischemic stroke treated with intravenous thrombolysis, early administration of oral aspirin will improve functional outcomes without increasing the risk of intracranial hemorrhage.

Conditions
- Acute Ischemic Stroke
- Cerebral Infarction
Interventions
- Aspirin
- Placebo
- Best medical management
Primary outcomes
- The proportion of patients with a modified Rankin scale (mRS) score of 0-1 at 90-day follow up. — Ninety days after stroke.
The mRS ranges from 0 to 6, with higher scores indicating a worse outcome. The primary outcome measure is based on the mRS score, which is dichotomized to define the excellent functional outcome as mRS score of 0-1 at 90-days follow up.
