Recruiting studies
- NCT04796714RecruitingPhase 4
Aspirin and clopidogrel after left heart appendix closure
This trial studies a “double anti-platelet” medicine plan (aspirin plus clopidogrel) after closing the left atrial appendage, a procedure used to reduce stroke risk in some heart rhythm conditions. It aims to find a safer, better medicine strategy for people who cannot take standard blood thinners.
PessacAges 18 years+ - NCT04701749Recruiting
Stopping blood thinners with a left-atrial device in bleeding risk
This trial studies whether it’s safe to temporarily stop blood-thinning medicine in people with long-term atrial fibrillation who have bleeding from a radiation-damaged bladder. It uses a procedure with a device placed in the left atrium to help lower stroke risk while reducing bleeding risk.
Clermont-FerrandAges 18 years+ - NCT04347187Recruiting
Long-term blood-thinner study for atrial fibrillation patients
This trial follows people with atrial fibrillation to see how long-term blood-thinning treatment affects outcomes over time. It may help determine which long-term approach best lowers stroke and clot risks for patients like you.
MoscowAges 18 years+ - NCT04258488RecruitingPhase 4
Blood thinner pill vs warfarin after mechanical aortic valve
This study compares a blood thinner pill (a factor Xa inhibitor) with warfarin (vitamin K antagonist) in people who have had a mechanical aortic valve replacement. It looks at which option works better and is safer over the long term.
Bucheon-siAges 19 years+ - NCT04298723Recruiting
Left atrial appendage closure vs blood thinners after brain bleed
This trial compares a procedure that blocks a heart blood-choke point (the left atrial appendage) versus taking blood thinners by mouth. It is for people with atrial fibrillation who have had a brain bleed and may be safer avoiding long-term blood thinners.
Mannheim, Baden-WurttembergAges 18 years+ - NCT04273607RecruitingPhase 2/Phase 3
Test an ECMO approach without blood thinners for lung failure
This trial studies whether people on a breathing machine called VV-ECMO can be managed without routine blood thinners, to reduce bleeding risk. It is meant for adults with severe lung failure (ARDS) and checks that it is safe for you to avoid anticoagulation.
Toronto, OntarioAges 18 years+ - NCT03907046RecruitingPhase 3
Blood thinner study to prevent stroke after brain bleed
This Phase 3 study tests whether a blood thinner (apixaban) can help prevent another stroke and support recovery after you’ve had a brain bleed. You would be assigned to a treatment group, and the study checks safety and whether strokes can be reduced without causing dangerous bleeding.
Birmingham, AlabamaAges 18 years+ - NCT03524222Recruiting
Home hospital care for adults after sudden illness
This trial tests whether certain adults can safely receive hospital-level care at home instead of staying in the hospital, using a home care team. It may help you recover in your own home if your condition fits their plan and you have support at home.
Boston, MassachusettsAges 18 years+ - NCT03504007Recruiting
Patient registry for people starting blood thinners after a clot
This registry collects information from people who had a clot (venous thromboembolism) and start blood thinners soon after diagnosis. It may help doctors better understand treatment patterns and outcomes after early blood-thinner use.
Rochester, MinnesotaAges 18 years+ - NCT03243175RecruitingPhase 3
Avoiding blood thinners after brain bleeding in atrial fibrillation
This Phase 3 trial studies whether it’s safer to avoid long-term blood thinners after a spontaneous brain bleed in people with atrial fibrillation (an irregular heart rhythm). It compares different prevention strategies to lower the risk of stroke or other blood-vessel problems without causing new, serious bleeding.
LilleAges 18 years+ - NCT03244020Enrolling by invitationPhase 4
Aspirin or low-dose blood thinner after bone or leg surgery
This trial compares aspirin versus a low-dose injectable blood thinner (LMWH) to prevent blood clots after certain orthopedic cancer surgeries. It may help lower the risk of dangerous clotting while balancing bleeding and side effects.
Los Angeles, CaliforniaAges 18 years+ - NCT03152058RecruitingPhase 2
Certolizumab for pregnancy in people with APS
This Phase 2 study tests whether certolizumab can improve pregnancy outcomes in people with antiphospholipid syndrome (APS). It targets pregnancy complications related to APS while closely checking safety, infections, and certain health conditions.
New York, New YorkAges 18–40 - NCT02318342Recruiting
Testing blood-thinner treatment for clogged aortic bioprosthetic valves
This study checks whether a blood-thinning medicine can treat problems with a bioprosthetic (man-made tissue) aortic valve. It focuses on valve “clots” that can happen after either a catheter-based or surgery-based valve replacement.

Common questions
- Are there clinical trials for anticoagulation?
- Yes. Clin2 currently lists 157 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.
