Recruiting studies
- NCT02735707RecruitingPhase 3
Adaptive trial for severe pneumonia care in intensive care
This study tests ways to improve treatment for adults with severe pneumonia that lands them in the ICU, adjusting the plan as results come in. It may help your care team find better treatments for lung infection and breathing/heart support needs.
Jacksonville, FloridaAges 18 years+ - NCT02219984Recruiting
Survey of adults taking blood thinners in a patient registry
This study builds a registry by asking adults who take blood thinners (anticoagulants) about their experiences. It may help improve care by learning how these medicines are used in real life.
Bologna, BOAges 18 years+ - NCT07441382Recruiting
Comparing treatments for frail older adults with atrial fibrillation
This study tests whether combining a heart procedure (catheter ablation) with a device to close the left atrial appendage (LAAO) is safer or better than blood thinners alone for frail patients 75 years or older with atrial fibrillation and high stroke risk. It aims to find a treatment that reduces stroke while lowering bleeding risks.
Guangzhou, GuangdongAges 75 years+ - NCT07242326Enrolling by invitation
Blood Thinner Dose Check for Older Adults With AFib
This study looks at whether older adults with atrial fibrillation are taking the right dose of their blood thinner medicine. It aims to improve how doctors prescribe these medications in primary care.
Ordu, OrduAges 65 years+ - NCT05997914Enrolling by invitation
Storytelling to reduce stroke risk in African Americans with atrial fibrillation
This study tests whether a storytelling program can help African American patients with atrial fibrillation start taking blood thinners as recommended by their doctor. The goal is to reduce stroke risk and improve health outcomes.
Jacksonville, FloridaAges 18 years+ - NCT06676085Recruiting
New ECMO blood-thinning strategy with nafamostat
This study tests a new way to manage blood-thinning medicine during ECMO (a machine that helps your heart and lungs). The goal is to see if using a drug called nafamostat in the ECMO circuit along with lower doses of a standard blood thinner can reduce side effects like bleeding.
Beijing, Beijing MunicipalityAges 18 years+ - NCT03532399Recruiting
Bivalirudin dosing study for children having heart procedures
This study looks at how the blood-thinner bivalirudin moves through the body in children during certain heart procedures. It may help doctors choose safer, more accurate dosing for pediatric anticoagulation.
Boston, MassachusettsAges Up to 17 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+ - NCT06863155Recruiting
A thin heart stent for people on blood thinners
This trial tests a new type of heart stent in people who also take daily blood thinners. The stent is very thin and releases medicine over time to help keep the artery open, and the coating eventually dissolves. It may be a safer option for people on blood thinners who need a stent.
AlbaceteAges 18 years+ - NCT06429787Recruiting
Safety study of BALFAXAR vs. Kcentra for urgent blood thinner reversal
This study compares the safety of two medications, BALFAXAR and Kcentra, used to quickly reverse the effects of blood thinners (like warfarin) in people who need urgent surgery or a procedure. It helps doctors understand which option may be safer for patients in this situation.
Boston, MassachusettsAges 18 years+ - NCT06276010Recruiting
Nafamostat mesilate for blood thinning in ECMO patients
This trial tests a medicine called nafamostat mesilate to prevent blood clots in patients who need ECMO (a machine that helps your heart and lungs) after heart surgery. It may offer a safer way to thin the blood compared to standard treatments.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05782270RecruitingPhase 4
Blood thinner medicines after bypass surgery with artery unblocking
This trial studies which blood-thinning medicine combination is safest and most helpful after coronary bypass surgery combined with a procedure to unblock the artery (endarterectomy). It focuses on preventing dangerous blood clots while also avoiding excess bleeding.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05588284Enrolling by invitation
Check whether a special treatment protects vein valves after clot
This study enrolls people with an acute blood clot in the thigh or pelvis veins to see how well a procedure called PCDT (using a Zelante device) preserves the function of vein valves. It may help reduce complications like ongoing vein problems after a clot.
Chuzhou, AnhuiAges 18–80 - NCT05283174Recruiting
Blood thinner use during stroke to predict outcomes
This study looks at how people doing well on certain blood thinners do when they have a stroke or bleeding while taking them. It will measure medication levels in your blood to understand stroke severity and recovery in the short and long term.
TaipeiAges 20 years+ - NCT05169242Recruiting
Preventing bleeding after colonoscopy using preventive clip placement
This trial tests whether placing small “preventive clips” during colonoscopy can reduce bleeding afterward in people who take blood thinners (DOACs). It may help lower the chance of bleeding after polyp removal or biopsy during a scheduled colonoscopy.
Shatin, New TerritoriesAges 18 years+ - NCT05028777Recruiting
People with a heart clot who can join a hospital record study
This study looks at people age 18+ who were found to have a blood clot in the left side of the heart (left ventricular thrombus) on scans between 2013 and 2020. It will compare how different blood-thinner medicines were used and what outcomes occurred.
BernAges 18 years+ - NCT06275555Recruiting
Bivalirudin for blood thinning in ECMO patients
This trial tests if bivalirudin is a safe and effective blood thinner for people on ECMO, a machine that helps your heart and lungs. You may be eligible if you need this therapy and have no past reactions to similar medicines.
Beijing, Beijing MunicipalityAges 18 years+ - 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.
Los Angeles, CaliforniaAges 18 years+ - NCT06482333Recruiting
When to restart blood thinners after polyp removal
This trial looks at the best time to restart direct oral anticoagulants (blood thinners) after having polyps removed during a colonoscopy. It aims to find a balance between preventing bleeding and reducing the risk of blood clots.
Hong KongAges 40 years+ - NCT06487052Recruiting
Catheter-based clot-dissolving drug for intermediate-high risk pulmonary embolism
This trial tests whether a standard procedure using a catheter to deliver clot-dissolving medicine directly into the lung artery works well for people with a serious but not immediately life-threatening blood clot in the lungs (pulmonary embolism). It aims to improve heart function and reduce long-term complications.
Saint PetersburgAges 18 years+ - NCT06753838Recruiting
Choosing Blood Thinners for Clotting Tests Using PFA-200
This study looks at how well a blood test (PFA-200) works to check clotting in people who take different types of blood thinners. You don't need any extra procedures—just your regular blood draw.

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.
