Clermont-FerrandAges 18–55 - NCT06581965RecruitingPhase 4
Personalized blood clot prevention for hip or knee replacement
This trial compares a personalized approach to preventing blood clots after hip or knee replacement surgery with the standard one-size-fits-all method. The goal is to see if tailoring prevention to each patient works better and is safer.
Apeldoorn, GelderlandAges 18 years+ - NCT06440694RecruitingPhase 3
Colchicine to reduce inflammation after a first blood clot in the leg
This trial tests if colchicine, a medicine used for gout, can reduce inflammation after a first deep vein thrombosis (blood clot in a large leg vein). It might help prevent long-term leg problems from the clot.
Ottawa, OntarioAges 18 years+ - NCT06418633Recruiting
Walking test after a provoked blood clot
This study looks at how a 60-minute walking test affects blood clotting in people who have had a provoked blood clot (from a known cause like surgery or birth control) compared to similar people who have never had a clot. It helps understand how the body's clotting system works after such a clot.
Nîmes, OccitanieAges 18–65 - NCT06393764Recruiting
Blood clots in cancer patients: a long-term study
This study follows people who have both cancer and a blood clot. It aims to learn more about how these clots happen and how they are treated in cancer patients, so doctors can improve care.
BrestAges 18–80 - NCT06357403Recruiting
Predicting blood clots in ICU patients with a blood test
This study looks at whether a blood test measuring a substance called anti-factor Xa activity can help predict dangerous blood clots in critically ill patients. If you join, researchers will follow you to see if the test results can prevent clots.
Graz, StyriaAges 18 years+ - NCT06348459Recruiting
Catheter treatment for severe pulmonary embolism
This study looks at how well a catheter (a thin tube) works to treat a serious type of blood clot in the lungs. It is for people who have a large clot that is causing problems like fast heart rate or low blood pressure.
Madrid, MadridAges 18 years+ - NCT05719415Recruiting
Testing balloon treatment effects on lung blood-vessel surface area
This study looks at how a procedure called balloon pulmonary angioplasty changes measurements in lung blood vessels in people with chronic thromboembolic pulmonary hypertension. It may help doctors understand what changes the treatment makes and why.
Montreal, QuebecAges 18–75 - NCT01158482Recruiting
Track outcomes after placing or removing an IVC filter
This study follows adults who are getting an IVC filter placed or removed. It aims to better understand how patients do after the procedure, both in the short term and longer term.
Stanford, CaliforniaAges Any age - NCT06286891Recruiting
Frailty and lung function after pulmonary endarterectomy
This study looks at how frailty, physical ability, and lung function change in people who have had surgery to remove blood clots from the lungs (pulmonary endarterectomy). It aims to help doctors better understand recovery after this procedure.
São Paulo, São PauloAges 18 years+ - NCT06195540RecruitingPhase 3
Rivaroxaban versus LMWH for leg injuries needing a cast
This trial compares two blood thinners (rivaroxaban pills versus LMWH shots) to see which is better at preventing blood clots in people with leg injuries that require a cast or brace. If you qualify, you can receive one of these treatments while your leg heals.
AgenAges 18 years+ - NCT06166537Recruiting
Compression Stockings for Blood Clot Prevention After Surgery
This study tests if wearing compression stockings after surgery can help prevent blood clots in people who already need to take blood thinners for an extended period. The stockings are used in addition to the blood thinners.
BristolAges 18 years+ - NCT06168370Recruiting
Personalized blood thinners after TAVI vs. standard care
This trial tests whether a personalized plan for blood thinners after TAVI can reduce the risk of stroke or bleeding better than the current standard of one daily blood thinner. If you've had a successful TAVI and don't need specific other blood thinners, you might be able to join.
NieuwegeinAges 18–110 - NCT06057844Recruiting
PET scan to detect active blood clots
This study uses a special PET scan to see if it can detect active blood clots. It is looking for healthy volunteers to help test the imaging method, not people who already have a clot.
BrestAges 18 years+ - NCT04071327Recruiting
Pulmonary hypertension registry for patient experiences
This trial is a registry that collects health information from people with pulmonary hypertension to better understand the disease and improve care. You may be asked to share details about your diagnosis and visits, especially soon after you start seeing a specialized PH care center.
Phoenix, ArizonaAges birth+ - NCT06038630RecruitingPhase 2
Xenon gas MRI study for lung and heart health
This study uses a special MRI scan (Xenon gas imaging) to look at how well your lungs and heart are working. It is for people with certain lung conditions, those getting blood transfusions or phlebotomy, or healthy volunteers.

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.
