This study looks at people age 18+ who were found to have a blood clot in the left side of the heart (left ventricular thrombus) on scans between 2013 and 2020. It will compare how different blood-thinner medicines were used and what outcomes occurred.
BernAges 18 years+ - NCT06482333Recruiting
When to restart blood thinners after polyp removal
This trial looks at the best time to restart direct oral anticoagulants (blood thinners) after having polyps removed during a colonoscopy. It aims to find a balance between preventing bleeding and reducing the risk of blood clots.
Hong KongAges 40 years+ - NCT06571149RecruitingPhase 4
Blood thinners and clot-busting drugs for stroke
This trial tests whether giving a clot-dissolving medicine (alteplase or tenecteplase) is safe and effective for people who have had a stroke and are taking a blood thinner (DOAC) like apixaban or rivaroxaban. It aims to see if this treatment can still be given within a few hours of the stroke.
EisenstadtAges 18 years+ - NCT03642509Recruiting
Compare a heart procedure to blood-thinner pills for stroke prevention
This trial studies whether closing off part of the heart (the left atrial appendage) can prevent stroke as well as long-term newer blood-thinner pills. It may help people with atrial fibrillation who recently had a stroke or a warning stroke (TIA).
Aarhus, Central JutlandAges 18 years+ - NCT04700826RecruitingPhase 4
Preventing stroke, death, and memory decline in atrial fibrillation
This trial looks at ways to help people with atrial fibrillation lower their risk of stroke, premature death, and worsening memory. It may help by identifying which prevention approach works best for a broader community of patients.
Birmingham, West MidlandsAges 55–73 - NCT05712200RecruitingPhase 3
Abelacimab for atrial fibrillation when blood thinners aren’t suitable
This Phase 3 study tests whether abelacimab can prevent stroke and other blood-clot problems in people with atrial fibrillation (or atrial flutter) who cannot safely take usual mouth blood thinners. It also looks at safety, especially bleeding risk.
Birmingham, AlabamaAges 65 years+ - NCT05070169Recruiting
Early surgery for hip fractures in people on blood thinners
This study looks at whether fixing a hip fracture sooner is better for people who take a direct oral anticoagulant (DOAC) blood thinner. It compares early surgery versus delayed surgery in people whose delay is specifically from the blood thinner.
ViennaAges 18 years+ - NCT05198960RecruitingPhase 3
Blood thinner drugs vs aspirin to prevent clot problems
This trial compares apixaban or rivaroxaban (blood thinners) against aspirin to prevent future clot-related complications in people with certain bone marrow diseases (PV, ET, or pre-PMF) that have a specific JAK2 mutation. It may help lower the risk of clots, but it also carefully considers bleeding risk.
AngersAges 18 years+ - NCT05333666Recruiting
Checking how blood NOAC levels relate to outcomes
This study looks at whether the amount of a blood thinner (NOAC) in your bloodstream is linked to health outcomes. It may help doctors better understand how to monitor and use these medicines safely.
Taipei, Please SelectAges 20 years+ - NCT05378308Recruiting
Tracking blood thinner use in people with AF or blood clots
This registry study looks at how people with atrial fibrillation (AF) or blood clots (VTE) use blood thinners, especially NOACs, over time. It may help doctors better understand real-world patterns of treatment and outcomes.
Zhengzhou, HenanAges Any age - NCT05498428RecruitingPhase 2
Amivantamab for advanced lung cancer with EGFR mutations
This Phase 2 study tests amivantamab (an antibody medicine) in people with advanced or metastatic non-small cell lung cancer that has specific EGFR gene changes. It may help shrink tumors or control cancer when standard curative treatments aren’t possible.
La Jolla, CaliforniaAges 18 years+ - NCT05955365RecruitingPhase 4
Single anticoagulant blood thinner after stent in atrial fibrillation
This trial tests whether taking a single “P2Y12 inhibitor” blood thinner (instead of multiple medicines) is safe and effective after you get a coronary stent. It’s for people with atrial fibrillation who need long-term blood thinning and have recently had a successful stent procedure.
HasseltAges 18 years+ - NCT06021808Recruiting
LAA clip vs. blood thinners to prevent stroke in non-paroxysmal AF
This study compares two ways to prevent stroke in people with persistent or long-standing atrial fibrillation (AF): taking a blood thinner (NOAC) or having a minimally invasive procedure to clip off the left atrial appendage (LAA). The goal is to see which approach works better at preventing stroke without causing major bleeding.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06216769Recruiting
Pill-in-the-pocket blood thinners after AF ablation
This study tests a 'pill-in-the-pocket' approach for blood thinners after a catheter ablation for atrial fibrillation. Instead of taking a daily blood thinner, you may only take it when needed, which could reduce the risk of bleeding while still preventing strokes.
SeoulAges 19–89 - NCT06362343Recruiting
Personalized dosing study for Xa inhibitor blood thinners
This study looks at how the body processes a certain type of blood thinner (Xa factor inhibitors) to help doctors find the right dose for each person. If you have a blood clot in your lungs and are on long-term treatment, this trial might help improve your care.
Beijing, Beijing MunicipalityAges 18–120 - NCT06429332RecruitingPhase 4
Care bundle study for brain bleed on CT scan
This trial is testing a set of standard care steps (a 'care bundle') for people who have a sudden brain bleed (intracerebral hemorrhage) that shows up on a CT scan. It aims to see if this bundle improves recovery and outcomes.
Oklahoma City, OklahomaAges 18 years+ - NCT06556446Recruiting
Clot-busting drug after stroke if on blood thinner
This study looks at whether giving a clot-busting medicine (IV thrombolysis) is safe and effective for people who have had a stroke and also recently took a direct oral anticoagulant (DOAC). If you've taken a DOAC in the last 48 hours, this trial may help doctors decide the best treatment for you.
InnsbruckAges 18 years+ - NCT06901466RecruitingPhase 4
Blood thinner study after heart valve repair
