This study tests a needle-free connector with anti-reflux technology, a special stopper that prevents blood from flowing back into IV catheters. The goal is to see if it reduces complications like blockages, infections, and pain compared to standard connectors. The trial will inv…

This study looks at whether a special blood test (TEG-PM) can guide doctors in adjusting blood-thinning medications for people who have had leg artery surgery for peripheral artery disease. About 130 adults will have their blood tested before and up to 9 months after surgery, and…

This early-phase trial tests an investigational biologic called EA5 in adults with antiphospholipid syndrome (APS) who have had two or more blood clots despite standard blood-thinning therapy. The study enrolls about 12 participants and gives EA5 by intravenous infusion followed …

This study compares two approaches—short-term anticoagulation (stronger blood thinners) versus antiplatelet therapy (milder blood thinners)—to prevent clots on a device placed in the heart's left atrial appendage. The trial involves 510 adults who have had this procedure. The goa…

This study reviews the medical records of 500 people who had surgery on major arteries (not heart surgery). It aims to see if taking blood thinners (antiplatelet or anticoagulant drugs) around the time of surgery affects the chance of bleeding or blood clots. The researchers comp…

This study looks at 600 adults who take blood thinners and have a mild head injury but a normal first brain scan. Researchers want to know how often a delayed brain bleed happens within 24 hours and up to 4 weeks after the injury. They also track risks like blood clots or confusi…
