Recruiting studies
- 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+ - NCT06288906Recruiting
Mechanical Clot Removal for Deep Vein Thrombosis
This trial tests a mechanical device that removes blood clots from deep veins in the pelvis or leg. It may be an option if you have a large clot and are at low risk for bleeding.
Milan, ItalyAges 18 years+ - NCT06886516RecruitingEarly Phase 1
Blood thinner study for cancer patients with low platelets
This study tests if the blood thinner apixaban is safe and effective for cancer patients who have low platelets and a recent blood clot. It may offer a treatment option for those who cannot take standard blood thinners.
Boston, MassachusettsAges 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+ - NCT07439991Recruiting
Study of blood clot risks after lung cancer surgery
This study looks at why some people develop blood clots after lung cancer surgery. By tracking your recovery for 30 days, researchers hope to find better ways to predict and prevent clots in the future.
Changchun, JilinAges 18 years+ - NCT07102160Recruiting
Long-term safety and effectiveness of the Cleaner Vac system for blood clots
This study tracks how well the Cleaner Vac® system works to remove blood clots from leg veins over time. It may be an option for people with new or recent deep vein thrombosis (DVT) who are getting their first treatment.
Fort Lauderdale, FloridaAges 18 years+ - NCT02156401Recruiting
Study of tests and care to improve clot diagnosis
This study follows adults who may have a blood clot in the lung (pulmonary embolism) or leg (deep vein thrombosis), or who were found to have a clot by chance. It aims to improve how doctors diagnose, manage, and estimate risk, which may lead to better, more tailored care for you.
Mainz, Rhineland-PalatinateAges 18 years+ - NCT06451003Recruiting
Preventing blood clots after cancer surgery: a program trial
This trial tests a program to help people who had cancer surgery get medicine to prevent dangerous blood clots. If you had belly or pelvic cancer surgery and are not on blood thinners, you may be able to join.
Charleston, South CarolinaAges 18 years+ - NCT06480994Recruiting
Testing a new tool to help diagnose blood clots
This trial tests a new computer tool that helps doctors decide whether you likely have a blood clot in your leg or lung. If you have symptoms and are not already on blood thinners, you may be able to join.
Niort, SartresAges 18 years+ - NCT07400510Enrolling by invitation
Ultrasound for DVT diagnosis and treatment
This trial uses a bedside ultrasound to quickly diagnose deep vein thrombosis (DVT) and help guide treatment. It may help patients who have symptoms like leg swelling or pain.
Hershey, PennsylvaniaAges 18 years+ - 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+ - 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 - NCT04862468RecruitingPhase 2
Dexamethasone after clot removal to calm leg swelling
This Phase 2 study tests whether a steroid medicine called dexamethasone can reduce inflammation after a clot (DVT) is removed in the thigh/behind-knee veins. If it works, it may help improve recovery and reduce ongoing leg problems after the procedure.
Orange, CaliforniaAges 18–89 - NCT07335341Recruiting
Liberant thrombectomy system case survey
This survey collects feedback from doctors who used the Liberant system to remove blood clots. The results help understand how well the device works in real-life procedures.
Washington D.C., District of ColumbiaAges 22 years+ - NCT04694248Recruiting
Blood thinner plus antiplatelet after iliac vein stent
This trial looks at whether taking a blood thinner and an additional clot-prevention medicine (antiplatelet) after iliac vein stenting can improve treatment of certain deep vein clots. It may help prevent the clot from coming back or spreading, but it also increases bleeding risk, so careful eligibility screening is important.
Hangzhou, ZhejiangAges 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+ - NCT06731673Recruiting
HSP47 protein study in blood clots
This study looks at a protein called HSP47 in people with blood clots, heart attacks, or strokes caused by atrial fibrillation, compared to healthy volunteers. It aims to learn more about how blood clots form and may lead to better treatments.
Aarhus, Central RegionAges 18 years+ - NCT07749820Recruiting
Clot removal device for leg vein blood clots
This study tests a device that removes blood clots from the deep veins of your leg. It's designed to help people with recent or slightly older clots in the thigh or pelvic area, aiming to reduce symptoms and prevent complications.
ShanghaiAges 18 years+ - NCT06198816Recruiting
Ultrasound and balloon treatment for old leg clots
This study tests a new way to treat long-standing blood clots in the leg using ultrasound waves and a balloon procedure. It aims to improve blood flow and reduce symptoms like swelling and pain for people who haven't gotten better with standard treatments.
Milan, ItalyAges 18–75 - NCT06385353Recruiting
First leg clot size and long-term risk
This study looks at how the size and location of a first-time leg blood clot affects the risk of long-term problems like chronic pain or swelling. You may join if you have a new, symptomatic clot in one leg and haven't had one before.
Vichy, AllierAges 18 years+ - NCT06806540Recruiting
Peripheral artery disease in patients with deep vein thrombosis in the leg
This study looks at how many people with blood clots in their leg veins also have narrowing in their leg arteries. It uses an ultrasound test to check both conditions.
Bologna, BolognaAges 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.

Common questions
- Are there clinical trials for deep venous thrombosis?
- Yes. Clin2 currently lists 46 recruiting deep venous thrombosis 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 deep venous thrombosis 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 deep venous thrombosis 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.
