Summary

This trial is testing whether two drugs are better than one at preventing strokes.

Who is the study for?
Adults aged 30-80 with recent symptoms or signs of a stroke due to 70-99% blockage in a major brain artery, who can swallow pills and have certain heart or blood vessel conditions. Excluded are those with previous stent treatments for the lesion, bleeding disorders, severe liver issues, uncontrolled high blood pressure, substance abuse, certain heart conditions that could cause clots, planned major surgeries within 90 days after joining the trial, severe neurological deficits preventing independence, life expectancy under one year due to other illnesses.
What is being tested?
The study is testing if adding rivaroxaban or ticagrelor (or both) to aspirin is better than just clopidogrel plus aspirin at reducing the risk of another stroke or death from vascular causes within a year. Participants will be randomly assigned to one of these treatment combinations.
What are the potential side effects?
Possible side effects include increased risk of bleeding (gastrointestinal bleeds), bruising easily due to reduced clotting ability from anti-coagulant and anti-platelet drugs. There may also be digestive discomfort like stomach pain or indigestion and potential allergic reactions.
