Checking stroke and bleeding risks in atrial fibrillation
This study looks at how to better predict both stroke risk and bleeding risk in people with atrial fibrillation. It may help doctors choose safer blood-thinner treatment and follow-up plans.
ParisAges 18 years+ - NCT06523959RecruitingPhase 4
Blood clot prevention in abdominal or pelvic surgery
This trial tests whether a medication called apixaban (a blood thinner) can safely prevent blood clots after abdominal or pelvic surgery. It is for people who have a moderate risk of clots and bleeding, and who are not taking other blood thinners.

Study of REGN7508 vs. standard blood thinners after knee replacement
This trial compares a new blood thinner called REGN7508 to two standard blood thinners (apixaban and enoxaparin) to prevent blood clots after total knee replacement surgery. The goal is to see which is safer and more effective.

Common questions
- Are there clinical trials for thromboembolism?
- Yes. Clin2 currently lists 159 recruiting thromboembolism studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a thromboembolism trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a thromboembolism trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
