Chuo, ChibaAges Any age - NCT07140211RecruitingPhase 3
Low-dose heparin to prevent blood clots after childbirth
This trial is testing a short course of a low-dose blood thinner (heparin) to prevent dangerous blood clots in the legs or lungs after childbirth. It is for women who have certain risk factors that make clots more likely.
BadenAges 18 years+ - NCT06440694RecruitingPhase 3
Colchicine to reduce inflammation after a first blood clot in the leg
This trial tests if colchicine, a medicine used for gout, can reduce inflammation after a first deep vein thrombosis (blood clot in a large leg vein). It might help prevent long-term leg problems from the clot.
Ottawa, OntarioAges 18 years+ - NCT04234841Recruiting
Study of outcomes after aortic valve replacement
This study follows adults who are having aortic valve replacement (through surgery or a catheter) to see how often certain outcomes happen after the procedure. You may be asked for blood tests and scans at set times, and some people may also be offered a special CT scan.
Stevenage, HertforshireAges 18 years+ - NCT02972385Recruiting
Testing how genes affect warfarin dosing in Hispanic and Latino adults
This study looks at how a person’s genes may affect how they respond to warfarin, a blood-thinner, so dosing can be safer and more accurate. It specifically focuses on Hispanic and Latino adults.
Tucson, ArizonaAges 18 years+ - NCT03255928Recruiting
Study blood clot cell activity in people with a heart pump
This study looks at how your blood’s clot-forming cells (platelets) behave when you have a heart pump device placed (short-term or long-term). The results may help doctors better understand complications and how to manage them after implantation.
Milan, MIAges 18–75 - NCT03368651RecruitingPhase 3
Testing a pre-surgery infusion to improve liver cancer outcomes
This trial tests whether giving medicine directly into the liver blood vessels before surgery can improve survival for people with liver cancer that has a blockage (tumor in the portal vein). It compares this approach plus surgery versus surgery alone in a randomized study.
Guangzhou, GuangdongAges 18–75 - NCT03504007Recruiting
Patient registry for people starting blood thinners after a clot
This registry collects information from people who had a clot (venous thromboembolism) and start blood thinners soon after diagnosis. It may help doctors better understand treatment patterns and outcomes after early blood-thinner use.
Rochester, MinnesotaAges 18 years+ - NCT03571763Recruiting
Anti-clotting treatment study in stroke patients with small brain bleeds
This trial looks at how anti-clotting medicines affect small blood vessel bleeds in the brain (cerebral microbleeds) and larger bleeding in the skull after an ischemic stroke. It may help doctors choose safer prevention medicines for people who already have these small bleeds seen on brain MRI.
ShenyangAges 18 years+ - NCT03855592Recruiting
Cancer patients with blood clots: thrombosis and cancer registry
This study is a registry that collects information about blood clot events in people with cancer. The goal is to better understand how often clots happen and what patterns they follow, which can help improve care.
Alcoy, AlicanteAges 18 years+ - NCT04211181Recruiting
Prevent blood clots in hospitalized teens and adults
This study looks at a prevention plan to reduce the risk of hospital-acquired blood clots. It may help people who are expected to stay in the hospital for several days but do not already have a clot.
Beijing, Beijing MunicipalityAges 14 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.
