SeoulAges 19–80 - NCT04284839RecruitingPhase 3
Blood thinner pills vs warfarin after heart surgery
This trial compares two ways to prevent blood clots after open heart surgery: a “direct oral” blood thinner pill versus warfarin (a vitamin K antagonist). It may help find the safest and most effective option for people who develop atrial fibrillation after surgery.
Fitzroy, VictoriaAges 18 years+ - NCT06472518RecruitingPhase 4
Clot-busting treatment plus blood thinners for severe leg clots
This trial tests whether combining a clot-busting procedure (pharmaco-mechanical thrombolysis) with standard blood thinners works better than blood thinners alone for people with severe, recently formed deep vein clots in the upper leg.
NantesAges 18 years+ - NCT06021080Recruiting
Comparing kidney dialysis patterns on calcium levels with citrate blood thinner
This study compares different patterns of continuous kidney dialysis (called CRRT) to see how they affect calcium levels in the blood when using a citrate-based blood thinner. It may help find the safest way to manage calcium during treatment.
Fuzhou, FujianAges 18–100 - NCT07494877Recruiting
Anticoagulant therapy for infertility in women aged 20-45
This study looks at whether blood-thinning medication can improve the chance of pregnancy in women who have trouble conceiving. It focuses on how the medication affects the lining of the womb and its ability to accept an embryo.
Xi'an, ShaanxiAges 20–45 - NCT07024160RecruitingPhase 1
First-in-human study of MT1011 injection in healthy volunteers
This trial tests a new medicine called MT1011 given as an injection. Researchers want to see how safe it is and how the body handles it. Healthy people can join to help find the right dose for future studies.
Beijing, Beijing MunicipalityAges 18–45 - NCT07658989Recruiting
Blood thinners in pregnancy with mechanical heart valves
This study looks at the best way to manage blood thinners for pregnant people who have mechanical heart valves. It aims to find the safest approach for both the mother and the baby.
Toronto, OntarioAges 18–45 - NCT07520890Recruiting
Bleeding Risk During Oral Biopsies in Patients on Blood Thinners
This study looks at whether patients taking certain blood-thinning medications (DOACs) have more bleeding during oral biopsies—small tissue samples taken from the mouth. Understanding this helps doctors know how to safely care for patients on these medications.

Common questions
- Are there clinical trials for anticoagulation?
- Yes. Clin2 currently lists 159 recruiting anticoagulation 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 anticoagulation 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 anticoagulation 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.
