Blood test may allow stroke patients to stop one drug earlier, lowering bleeding risk

NCT ID NCT07644234

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether people who have had a minor stroke or a high-risk mini-stroke can safely stop one of their two blood thinners earlier than usual. About 3,800 participants will have their blood tested to see how they respond to the drug clopidogrel. Those who are sensitive to it will be randomly assigned to take the two drugs for 7 days or the standard 21 days, then switch to one drug. The goal is to see if the shorter course reduces bleeding risk without increasing the chance of another stroke.
