A Randomised, Double-Blind, Multinational Study to Prevent Major Vascular Events With Ticagrelor Compared to Aspirin (ASA) in Patients With Acute Ischaemic Stroke or TIA.

The primary objective of the study is to compare the effect of 90-day treatment with ticagrelor (180 mg \[two 90 mg tablets\] loading dose on Day 1 followed by 90 mg twice daily maintenance dose for the remainder of the study) vs acetylsalicylic acid (ASA)-aspirin (300 mg \[three 100 mg tablets\] loading dose on Day 1 followed by 100 mg once daily maintenance dose for the remainder of the study) for the prevention of major vascular events (composite of stroke, myocardial infarction \[MI\], and death) in patients with acute ischaemic stroke or transient ischaemic attack (TIA).
