Pair Antiplatelet THerapy in Ischemic Stroke With Intracranial Artery Stenosis (PATH-ICAS)

June 17, 2024 updated by: Nengwei Yu, Sichuan Provincial People's Hospital

The goal of this clinical trial is to learn about efficacy and safety of dual antiplatelet therapy in ischemic stroke with intracranial artery stenosis. The main question it aims to answer are:

whether aspirin combined with clopidogrel for 3 month is better than 1 months for patients with non-cardiogenic cerebral infarction with intracranial artery stenosis.

Participants will get dual antiplatelet therapy (aspirin plus clopidogrel) for 1 month or 3 months within 7 days of the first stroke.

Researchers will compare experimental group (3 months dual antiplatelet therapy) with comparison group (1 month dual antiplatelet therapy), to see if experimental group would reduce stroke recurrence or mortality, and increase bleeding and other adverse prognosis.
