Blood clot control during TIPS in people with cirrhosis
This study looks at how to manage blood clotting around the time of a TIPS procedure in adults with cirrhosis, to see if a safer clotting strategy helps. It may be useful if you are having TIPS for a specific complication of liver disease.
GrazAges 18 years+ - NCT04524637Recruiting
Testing a clotting test in recent traumatic brain injury
This trial tests whether a special blood clotting test called thromboelastography can help assess clotting problems after a head injury. It may help doctors better understand bleeding risk and related complications early after trauma.
ShanghaiAges 18–80 - NCT04647227RecruitingPhase 4
SEVENFACT® to reduce bleeding in hemophilia with inhibitors
This trial studies whether SEVENFACT® can reduce bleeding episodes in people with hemophilia A or B who have inhibitors (proteins that make standard treatments less effective). It also tests how well people can track bleeding and medicine use during the study.
Phoenix, ArizonaAges 12–100 - NCT04947657Recruiting
Atrial fibrillation blood and heart scan pilot during ablation
This study looks at blood-related “clotting” signs and heart scan results in people with atrial fibrillation (AF) who are getting a catheter ablation. It may help doctors better understand AF and choose treatments more precisely.
New Orleans, LouisianaAges 18–120 - NCT05139589Recruiting
Collecting data from adults with heart valve infection
This study collects information about adults who are treated in Amsterdam UMC for infective endocarditis (a serious infection of the heart valves). The goal is to better understand this condition—especially for people undergoing heart valve surgery—by comparing them to similar surgery patients who do not have an infection.
Amsterdam, North HollandAges 18 years+ - NCT05156983RecruitingPhase 3
Reversal drug for urgent surgery in people on Factor Xa blood thinners
This Phase 3 study tests TAK-330, a reversal (blocking) medicine, to reduce bleeding risk during urgent surgery for adults taking Factor Xa inhibitors like rivaroxaban, apixaban, or edoxaban. It’s for situations where surgery can’t wait and doctors need a fast way to restore normal clotting.
Arkansas City, ArkansasAges 18 years+ - NCT05223985Recruiting
Testing a brain-recording device for focal epilepsy mapping
This study tests how well a specific brain-recording device works during a procedure used to map seizure origins in people with drug-resistant, disabling focal epilepsy. It may help doctors plan treatment by improving how well they can localize the seizure focus before possible surgery.
MarseilleAges 1.5 years–65 years - NCT05313620RecruitingPhase 4
Tofacitinib effect on clotting tests in ulcerative colitis
This study looks at how tofacitinib (and related medicines) may affect clotting and blood-platelet function, and whether this could relate to blood clot risk. It includes detailed blood and stool/colonoscopy-related testing in adults with ulcerative colitis and in some people without it.
Madrid, MadridAges 18 years+ - NCT05411614Recruiting
Testing two heart procedures for atrial fibrillation in heart failure
This study compares two different ablation procedures (treatments that target heart rhythm triggers) for people with atrial fibrillation and reduced heart pumping. It aims to see which approach works best and is safest for improving your heart rhythm when you also have heart failure.
