Bleeding Risk During Oral Biopsies in Patients on Blood Thinners
This study looks at whether patients taking certain blood-thinning medications (DOACs) have more bleeding during oral biopsies—small tissue samples taken from the mouth. Understanding this helps doctors know how to safely care for patients on these medications.
Pisa, PiAges 18 years+ - NCT05723926Recruiting
Carotid implants to help prevent stroke repeat in atrial fibrillation
This trial tests whether placing a carotid implant can reduce the chance of having another stroke in people with atrial fibrillation who are already taking blood thinners. It aims to prevent stroke recurrence while you continue prescribed anticoagulation.
Rockford, IllinoisAges 18 years+ - NCT06823466Recruiting
Stroke study for patients on blood thinners
This study looks at people who had a stroke while taking blood thinners (anticoagulants) for an irregular heartbeat. It aims to learn more about these strokes and how to better prevent them in the future.
ZagrebAges 18 years+ - NCT06696079Recruiting
Early vs later blood thinner restart after brain bleed surgery in atrial fibrillation
This trial compares restarting a blood thinner early (within a few days) versus later (after about a week) in people who have a chronic subdural hematoma drained and also have atrial fibrillation. The goal is to find out which timing helps prevent both new bleeding and blood clots.
Oulu, North OstrobothniaAges 18 years+ - NCT06869811Recruiting
Stroke prevention after failed blood thinners
This study is for people who had a stroke despite taking blood thinners for atrial fibrillation. It tests if adding a procedure to close the left atrial appendage (a small pouch in the heart) to your blood thinner is better than just taking the blood thinner alone to prevent another stroke.
Barcelona, BarcelonaAges 18–95 - NCT06947707Recruiting
Blood thinners for brain blood clot in Chinese patients
This trial tests two blood thinner medicines, edoxaban and rivaroxaban, in Chinese patients with a blood clot in a brain vein (cerebral venous thrombosis). It aims to see if these medicines are safe and work well.
Beijing, Beijing MunicipalityAges 18–80 - NCT04660747Recruiting
Anticoagulant medication choices for cerebral venous thrombosis
This study looks at people with cerebral venous thrombosis who were treated with blood thinners taken by mouth (or started within the first 30 days). It uses observational data to understand how these treatments are used and what outcomes may follow.
Amsterdam, North HollandAges 18 years+ - NCT06322953RecruitingPhase 3
Timing to restart blood thinners after head injury bleeding
This trial looks at when it is safest to restart blood thinners after a traumatic brain bleed. It compares restarting at 4 weeks versus 8 weeks in people on blood thinners before their injury.
Plymouth, DevonAges 18 years+ - NCT07242326Enrolling by invitation
Blood Thinner Dose Check for Older Adults With AFib
This study looks at whether older adults with atrial fibrillation are taking the right dose of their blood thinner medicine. It aims to improve how doctors prescribe these medications in primary care.
Ordu, OrduAges 65 years+ - NCT05387954RecruitingPhase 3
PFO closure or blood thinners after stroke in ages 60–80
This trial studies the best way to prevent another stroke after a recent stroke in people ages 60 to 80 who have a “PFO” heart connection. It compares closing the PFO vs taking mouth blood-thinners or antiplatelet medicine, based on what your doctors determine is safest for you.
AmiensAges 60–80 - NCT06194617Recruiting
Rivaroxaban for older Chinese patients with blood clots in lungs
This trial tests whether a blood thinner called rivaroxaban (a pill) works well for older Chinese patients who have had a blood clot in their lungs and are now on long-term treatment. It aims to see if it's safe and effective for this group.
Beijing, Beijing MunicipalityAges 18 years+ - NCT04262492Recruiting
Registry of adults with APS on blood thinners
This study keeps an international registry of people with antiphospholipid syndrome (APS) who are taking direct oral blood thinners. It may help doctors better understand how APS patients do over time and improve future care, even if you’re not asked to change treatment.
NancyAges Any age - NCT06692504Recruiting
Blood Thinner Side Effects in the Emergency Room
This study looks at side effects of blood thinners (anticoagulants) in patients who visited the emergency department. It helps doctors understand how to better manage these medications.
BesançonAges 18 years+ - NCT03297281Recruiting
Stopping or continuing blood thinners during prostate vaporization
This study compares whether people can safely stop or continue oral blood thinners during a prostate procedure called photovaporization. It may help reduce bleeding risk without increasing dangerous clot risks for the right patients.
ToulouseAges 18 years+ - NCT06957366Recruiting
Managing Blood Thinners Before High-Risk Surgery
This study looks at how to safely manage your blood thinner (DOAC) around the time of a planned, high-bleed-risk surgery or procedure involving a spinal needle. The goal is to find the best way to stop and restart your medication to prevent bleeding and clotting problems.
Hartford, ConnecticutAges 18 years+ - NCT04874428RecruitingPhase 1
Blood thinner pills in people with mild-to-moderate cirrhosis
This early study tests whether the blood thinner pills rivaroxaban and apixaban can be used safely in people with liver cirrhosis that is not too severe. It may help doctors understand the safest way to prevent or treat blood clots in this group.
BernAges 18 years+ - NCT04284839RecruitingPhase 3
Blood thinner pills vs warfarin after heart surgery
This trial compares two ways to prevent blood clots after open heart surgery: a “direct oral” blood thinner pill versus warfarin (a vitamin K antagonist). It may help find the safest and most effective option for people who develop atrial fibrillation after surgery.
Fitzroy, VictoriaAges 18 years+ - NCT06402851RecruitingPhase 4
Blood thinner or none for atrial fibrillation with dialysis
This trial compares two types of blood thinners (vitamin K antagonists and factor Xa inhibitors) versus no blood thinner in people with atrial fibrillation who are on dialysis or have very advanced kidney disease. It aims to see which option is safest and most effective for preventing strokes and bleeds.
Salvador, Estado de BahiaAges 18 years+ - NCT04045665RecruitingPhase 3
Blood thinner vs usual care for new heart rhythm after bypass surgery
This trial tests whether using a blood thinner in people with new, temporary atrial fibrillation after CABG (heart bypass surgery) can reduce harmful outcomes compared with standard treatment. It may help prevent stroke or other complications if your rhythm problem fits the trial’s timing and risk profile.
Little Rock, ArkansasAges 18 years+ - NCT03968393RecruitingPhase 4
Blood thinner to prevent stroke after stress-related irregular heartbeats
This trial tests whether taking a blood thinner can lower the risk of stroke in people who had atrial fibrillation (an irregular heartbeat) that happened temporarily around a stressful illness or surgery. It looks especially at people at higher risk for stroke after that episode.
Los Angeles, CaliforniaAges 55 years+ - NCT04977076Recruiting
Stopping versus continuing blood thinner during heart catheter procedures
This study compares whether you should temporarily stop your blood thinner (DOAC) or keep taking it when you have an elective heart catheter test or procedure (coronary angiography or PCI). It aims to see which approach is safer and better for preventing bleeding and clotting around the procedure.
Heerlen, LimburgAges 18 years+ - NCT07288489RecruitingPhase 3
A study on VMX-C001 for urgent surgery while on blood thinners
This trial tests a drug called VMX-C001 to quickly reverse the effects of certain blood thinners (Factor Xa inhibitors) in people who need urgent surgery with a high risk of bleeding. It compares VMX-C001 to standard care to see which is more effective at helping blood clot normally.
Chandler, ArizonaAges 18 years+ - NCT04298723Recruiting
Left atrial appendage closure vs blood thinners after brain bleed
This trial compares a procedure that blocks a heart blood-choke point (the left atrial appendage) versus taking blood thinners by mouth. It is for people with atrial fibrillation who have had a brain bleed and may be safer avoiding long-term blood thinners.
Mannheim, Baden-WurttembergAges 18 years+ - NCT06863155Recruiting
A thin heart stent for people on blood thinners
This trial tests a new type of heart stent in people who also take daily blood thinners. The stent is very thin and releases medicine over time to help keep the artery open, and the coating eventually dissolves. It may be a safer option for people on blood thinners who need a stent.
