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+ - NCT06798766Recruiting
Understanding darker skin tones and vein disease care
This study looks at how people with darker skin tones experience chronic venous insufficiency (a condition that affects blood flow in the legs) and aims to improve how it's diagnosed and treated. It involves two parts: one is sharing your experience through an interview, and the other includes a skin check and photos at the hospital.
London, LondonAges 18 years+ - NCT05050799Recruiting
Testing a new device to place central lines in harder cases
This study tracks how well a new device (the Surfacer System) works when standard methods can’t place a central venous line (a larger tube into a major vein). It may help people who need a long-term access line but have blocked veins where usual procedures don’t work.
Tucson, ArizonaAges 18 years+ - NCT05089227RecruitingPhase 2
Long-term apixaban to prevent clots in autoimmune hemolytic anemia
This Phase 2 trial tests whether taking long-term apixaban (a blood thinner) can prevent venous blood clots in people with autoimmune hemolytic anemia (AIHA). It may help reduce the risk of dangerous clotting events if you meet safety and risk criteria.
DijonAges 18 years+ - NCT07270263Recruiting
Lower-dose blood thinners for people with blood cancers
This trial compares lower doses of two common blood thinner pills (apixaban and rivaroxaban) to a daily injection (enoxaparin) to prevent blood clots in people receiving treatment for blood cancers like multiple myeloma, lymphoma, or certain other blood cancers.
Gdansk, Pomeranian VoivodeshipAges 18 years+ - NCT06873321RecruitingPhase 4
Blood thinners after leg artery surgery to prevent clots
This trial compares two blood-thinning strategies after leg artery surgery or angioplasty to prevent dangerous blood clots. Participants will receive either rivaroxaban plus aspirin or aspirin alone, and researchers will monitor for clots over 30 days.
Pernambuco, PernambucoAges Any age - NCT06906250Recruiting
European registry for leg vein blood clots
This trial is a registry (a database study) that tracks people with blood clots in the large veins of their legs or abdomen. It does not test any new drug or treatment, but helps doctors learn more about these conditions.
Marseille, FranceAges 18 years+ - NCT07737236Recruiting
Ruscus study for symptom relief in chronic vein problems
This study tests a natural plant extract called Ruscus to see if it helps control symptoms of chronic venous insufficiency, a condition where leg veins have trouble moving blood back to the heart. It is for people who are already starting this treatment as part of their regular care.
Ankara, AnkaraAges 18–75 - NCT06417541Recruiting
Study of blood clots from central lines using CT scans
This study uses special CT scans (photon-counting CT) to look for blood clots related to central lines, both in patients who have passed away and in living patients. It aims to better understand and detect these clots.
Lund, Skåne CountyAges 18 years+ - NCT06232551Recruiting
Hospital alert to prescribe rivaroxaban to prevent blood clots
This trial tests whether alerting your hospital doctor to prescribe a blood thinner called rivaroxaban (Xarelto) at discharge can help prevent dangerous blood clots in your legs or lungs. It is for patients who are at higher risk for clots but have a low bleeding risk.
Murray, UtahAges 18–110 - NCT04297085Recruiting
Study of why blood clots in veins come back
This study follows people who have had a vein blood clot (or related venous clot) to understand what factors may make the clot happen again. It may help clinicians find better ways to prevent repeat clots.
BrestAges Any age - 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 - NCT05627375RecruitingPhase 3
Blood thinner options for clot patients already on antiplatelets
This Phase 3 trial compares the best “blood thinner” approach for people who have a new clot in the leg (DVT) or lung (PE) and who already take antiplatelet medicines for heart or blood-vessel prevention. It aims to find an antithrombotic plan that lowers clot risk while managing bleeding risk.
AmiensAges 18 years+ - NCT05711173Recruiting
Study blood clot triggers and immune cell changes in clot patients
This study looks at how certain blood cell changes and immune system activity may relate to blood clots in specific veins or lungs. It may help researchers understand why clots happen “without a clear cause” and how to better predict risk.
BordeauxAges 6–50 - NCT05773638Recruiting
Study blood clots and heart disease in adults with Von Willebrand
This study looks at cardiovascular problems and blood-clot events (like deep vein clots or pulmonary embolism) in adults with Von Willebrand disease in western France. It may help doctors better understand who is at risk and how to manage these complications.
AngersAges 18 years+ - NCT03206372Recruiting
Study of blood clot risk during hormone use in families
This study looks at what increases the risk of deep vein thrombosis or a lung blood clot (venous thromboembolism) in women who are using hormones. Researchers compare close family members to understand inherited risk and hormone-related triggers, which may help with prevention in the future.
BrestAges 16 years+ - NCT04487314Recruiting
Study of chronic vein disease over time
This study follows people (and certain close family members) to document how chronic vein problems develop and change over time. You would get yearly checkups and ultrasound scans to track the natural course of the condition.

Common questions
- Are there clinical trials for venous disease?
- Yes. Clin2 currently lists 59 recruiting venous disease 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 venous disease 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 venous disease 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.
