- NCT06845423RecruitingPhase 4
Preventing blood clots after childbirth in women at intermediate risk

This trial tests a new anticoagulant medication to treat and prevent blood clots in patients with active cancer. You may qualify if you have a recent clot in your leg or lungs and are already taking a blood thinner.
Hialeah, FloridaAges 18 years+ - NCT06372730Recruiting
Predicting blood clot return after stopping blood thinners
This study uses a special 3D lung scan (V/Q SPECT/CT) to see if leftover blockages in your lungs can predict if another blood clot will come back. You may be eligible if your doctor has decided it's safe to stop your blood thinners after 3 to 6 months of treatment for a first blood clot.
Amiens, FranceAges 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+ - NCT07350499Recruiting

DOAC interruption study for Chinese people with atrial fibrillation
This trial studies how safely and effectively to pause a blood thinner (a DOAC) for about 48 hours before an elective procedure in people with atrial fibrillation. It may help confirm the best way to reduce bleeding risk without raising stroke risk.
Hong KongAges 18–80 - 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+ - 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+ - NCT03659708Recruiting
Study to prevent dangerous blood clots during pregnancy
This study looks at pregnancy-related risk for a dangerous blood clot in the leg or lung (venous thromboembolism). It focuses on pregnant people who already have a higher-than-average risk and wants to see how to manage that risk safely.
BronAges 18–50 - NCT06494878RecruitingPhase 3
Aspirin after childbirth to prevent blood clots
This trial tests if taking aspirin after delivery helps prevent dangerous blood clots in women with certain risk factors. It's for new mothers who have a clotting disorder, were on bed rest, or have multiple other risk factors like high weight or preeclampsia.
BrusselsAges 18 years+ - NCT05029063RecruitingPhase 3
Rivaroxaban to prevent clots in cancer patients with new catheters
This Phase 3 study tests whether the medicine rivaroxaban can prevent dangerous blood clots in people with cancer who have a central venous catheter placed recently. It may help reduce clot risk while your catheter is in place, but you must meet safety and bleeding-risk criteria.
Halifax, Nova ScotiaAges 18 years+ - NCT05756244Recruiting
Managing blood thinners during pregnancy to prevent clot problems
This study looks at the best way to manage blood thinners (like injections of LMWH) during pregnancy for people who need them because of a past or current blood clot risk. It may help by improving how safely and effectively anticoagulation is handled to reduce clot complications.
Durham, North CarolinaAges 18–60 - NCT06950697Recruiting
Blood clot risk prediction for lung cancer patients on immunotherapy
This study builds a tool to predict blood clot risk in lung cancer patients receiving immune checkpoint inhibitors. Researchers will use your data to develop a more personalized risk assessment, which may help prevent dangerous clots during treatment.
Zhengzhou, HenanAges 18 years+ - NCT03881345Recruiting
Registry for blood clots in legs or lungs
This registry collects information from people who have a blood clot in a leg or a clot in the lung. It helps researchers understand how these conditions are treated in real life.
Moscow, MoscowAges 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 - 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.

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.
MoscowAges 18 years+ - 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+ - NCT07196020Recruiting
Predicting blood clots during chemotherapy for certain cancers
This study looks at whether doctors can predict blood clots in people with certain cancers who are receiving chemotherapy. If you have ovarian, lung, stomach, or pancreatic cancer and are starting chemotherapy, you may be able to join and help improve clot prevention.

Common questions
- Are there clinical trials for venous thromboembolism?
- Yes. Clin2 currently lists 95 recruiting venous 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 venous 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 venous 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.
