Recruiting studies
- NCT05881798Recruiting
Vena cava filter data study for specific filter type
This study checks outcomes and safety using real-world health data from people who received a specific type of vena cava filter. It may help improve future care by understanding how these devices perform after placement.
Los Angeles, CaliforniaAges 18 years+ - NCT05735639RecruitingPhase 4
Prevention of blood clots during varicose vein treatment
This trial tests whether giving medicine to prevent blood clots during varicose vein treatment is safe and helpful. It focuses on people having a minimally invasive procedure on enlarged leg veins under local anesthesia.
LondonAges 18 years+ - NCT05701917Recruiting
Clot-busting device versus blood thinners for leg clot
This study compares a clot-removal device (ClotTriever) plus standard care versus standard blood thinners alone for a deep vein clot in the leg. It aims to see which approach better improves leg symptoms and outcomes.
Scottsdale, ArizonaAges 18 years+ - NCT05636748Recruiting
Study how blood clots affect stroke, using special scans
This study looks at how blood clots form and contribute to an acute ischemic (clot-related) stroke. It uses PET-CT scanning to better understand the process and may help improve how future stroke treatments are targeted.
EdinburghAges 18 years+ - NCT05484557Recruiting
Apixaban vs enoxaparin to prevent blood clots after spinal cord injury
This trial studies whether apixaban works as well as enoxaparin to prevent dangerous blood clots after spinal cord injury. If you qualify, you would take one of these medicines to lower clot risk during the recovery period.
RaananaAges 18 years+ - NCT04263038RecruitingPhase 4
Watchful waiting versus blood thinners for small lung clots
This trial compares close monitoring (“watch and wait”) versus taking the blood thinner rivaroxaban in people with a small type of lung blood clot. It aims to find out whether low-risk patients can safely avoid or reduce anticoagulation while still staying healthy.
Woluwe-Saint-Lambert, Brussels CapitalAges 18 years+ - NCT04295486RecruitingPhase 2
Low-dose aspirin to prevent blood clots after hip or knee surgery
This Phase 2 study tests the best dose of low-dose aspirin to help prevent dangerous blood clots after total hip or knee replacement surgery. If you’re at lower clot risk and can safely take aspirin, it may help reduce clot risk while you recover.
Miami, FloridaAges 19 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+ - NCT04206852Recruiting
Balloon treatment for chronic blood-clot lung vessel disease
This trial tests whether a procedure called balloon pulmonary angioplasty is safe and effective for people with chronic thromboembolic disease in the lungs, especially when surgery isn’t an option. If you have CTEPH, it may help improve lung blood flow and symptoms.
BeijingAges 18 years+ - NCT03728166Recruiting
Computer guidance to prevent blood clots after hospital stay
This trial tests a computerized tool that helps doctors decide who needs prevention medicines to lower the risk of blood clots after a hospital stay. It may help reduce preventable clotting risk for people who are less mobile and have added risk factors.
Boston, MassachusettsAges 40 years+ - NCT03636295RecruitingPhase 3
Testing a lower INR goal to reduce bleeding in mechanical valves
This Phase 3 study tests whether aiming for a lower blood-thinning test result (INR) can reduce bleeding risk in people with a specific type of mechanical heart valve. The trial checks if this lower INR goal is safer while still protecting against dangerous clots.
Genk, LimburgAges 18 years+ - NCT03388476Enrolling by invitation
Breathing carbon dioxide measurement to detect lung high blood pressure
This trial tests whether measuring carbon dioxide you breathe out can help detect pulmonary hypertension earlier. It may help doctors spot this lung blood vessel condition sooner, especially around the time you get a heart test.
Giessen, HesseAges 18 years+ - NCT03407469Recruiting
Study of taking blood thinners and quality of life in cancer clots
This study looks at how people with cancer-related blood clots in the leg or lungs do with anticoagulant (blood thinner) treatment over at least 3 months. It also tracks quality of life and healthcare use, which may help improve supportive care for patients.
Houston, TexasAges 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+ - NCT03041805Recruiting
Check whether a clot-risk score predicts recovery after vein surgery
This study looks at how well a clot-risk score (Caprini score) relates to blood clot checks and outcomes after varicose vein surgery. You may be asked to have an ultrasound scan a few weeks after your operation and be followed for about 4 weeks.

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.
