Recruiting studies
- 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+ - 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+ - 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+ - NCT06386107Recruiting
Bleeding risk in people with cancer and blood clots on blood thinners
This study looks at how well blood thinners work in people with cancer and a recent blood clot. It measures the risk of bleeding by checking certain blood clotting factors.
Clermont-FerrandAges 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+ - NCT07650435Recruiting
Clot removal in pulmonary embolism trial
This study tests a procedure to remove blood clots from the lungs in people with moderate or severe pulmonary embolism. It may help reduce strain on the heart and improve recovery.
PlymouthAges 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 - NCT05098769Recruiting
Prediction tool for risks after acute pulmonary embolism scans
This trial studies a tool that uses CT scan results and heart blood tests to predict the chance of serious outcomes after an acute pulmonary embolism (a blood clot in the lung). It may help doctors identify higher-risk patients sooner.
Shenyang, LiaoningAges 18 years+ - 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+ - NCT06683157Recruiting
Study of calf vein clots with ultrasound monitoring
This study follows people with a blood clot in the calf vein to learn how the clot changes over time using repeat ultrasound scans. It may help doctors understand who needs treatment and who can be watched safely.
Dresden, SaxonyAges 18 years+ - NCT06585228Recruiting
Heart CT vs ultrasound to find clots after stroke
This study compares two ways to look for blood clots in the heart after a stroke: a heart CT scan and an ultrasound done through the food pipe. It aims to see if the CT scan can spot clots just as well as the more invasive ultrasound.
Amsterdam, North HollandAges 18 years+ - NCT06709833Recruiting
Blood clot risk study for brain tumor patients
This study looks at blood clotting risks in people having surgery for meningioma or glioma brain tumors, and compares them to healthy volunteers. It may help doctors better understand and prevent blood clots after brain tumor surgery.
Tübingen, Baden-WurttembergAges 18 years+ - NCT04436978RecruitingPhase 4
Best blood thinner plan for atrial fibrillation after stent
This study compares different blood-thinner (“antithrombotic”) strategies in people with atrial fibrillation or flutter who recently had a stent placed (PCI). It aims to find a plan that lowers clot risk while keeping bleeding risk as low as possible.
AalstAges 18 years+ - NCT04615065Recruiting
Biobank study collecting emergency data for very sick patients
This study collects health and sometimes blood sample information from people arriving at the emergency department with high-risk or serious conditions. The goal is to build a large emergency “biobank” to help researchers better understand and improve urgent care.
GroningenAges 18 years+ - 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 - NCT05112705Recruiting
Finding deep vein clots early in ICU patients
This study focuses on diagnosing deep-vein thrombosis (DVT, blood clots in the leg) early in people who are very ill in the ICU. It aims to test an approach to better detect clots sooner, which could help prevent complications.
Riyadh, Riyadh RegionAges 18 years+ - NCT05482269Recruiting
Using CT scans to predict outcomes after lung blood clots
This trial uses an artificial intelligence (AI) system to read CT scan images of the lungs and predict outcomes after a pulmonary embolism (a blood clot in the lung). It may help doctors identify who is at higher risk, so treatment decisions can be faster and more accurate.
Shenyang, LiaoningAges 18 years+ - NCT06727669Recruiting
Long-term study of blood clotting and bleeding disorders
This study observes patients with blood clotting or bleeding disorders over time to collect health information and improve care.
Beijing, Beijing MunicipalityAges Any age - NCT05476913Recruiting
Preventing blood clots after stroke with a leg device
This study checks whether using a special device on the legs can help prevent dangerous blood clots after an acute stroke. You may be eligible if you recently had a stroke and you’re not able to get up and walk to the toilet without help.
Bury St Edmunds, SuffolkAges 18 years+ - NCT05568966Recruiting
Blood sample collection for new diagnostic tests
This study collects small blood samples to help test and improve new diagnostic devices. You may be eligible if you’re an adult with certain symptoms that match one of several health “groups,” and if you can consent and read English.
Airdrie, ScotlandAges 18 years+ - NCT05853796Recruiting
Studying stroke warning signs in young adults
This observational study follows people ages 18–50 who had a first TIA (“mini-stroke”) or an acute ischemic stroke to better understand what happens after the event. It may help improve future care by tracking symptoms, imaging findings, and recovery over time.
Nijmegen, GelderlandAges 18–50 - NCT06051032Recruiting
Comparing balloon vs. suction for clotted dialysis fistulas
This study compares two ways to clear a sudden clot in a dialysis fistula (AVF). It uses either a balloon (to push the clot out) or a suction device (to pull the clot out) to restore blood flow.
Valencia, ValenciaAges 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+ - 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.

Common questions
- Are there clinical trials for embolism and thrombosis?
- Yes. Clin2 currently lists 37 recruiting embolism and 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 embolism and 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 embolism and 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.
