This study tests whether adding colchicine, an anti-inflammatory pill, to standard blood thinners can prevent long-term vein damage after a deep vein thrombosis (DVT) in the leg. About 940 adults with a first acute DVT will receive either colchicine or a placebo for six months an…

This study tests whether using a catheter to deliver clot-busting drugs or a device to physically remove the clot can help people with acute deep vein thrombosis (DVT) who do not improve after one week of blood thinners. About 100 adults aged 18 to 75 with acute DVT in the leg wi…

This study will compare aspirin tablets to daily injections of low molecular weight heparin (LMWH) for preventing dangerous blood clots in people who break their hip. Over 21,000 patients aged 60 and older across 96 UK hospitals will take part. Hospitals will switch between the t…

This pilot study tests whether a combination of two blood thinners (rivaroxaban and aspirin) can prevent heart attacks and blood clots in patients who had a hip fracture surgery and also suffered a heart injury. About 100 adults aged 45 and older will be randomly assigned to eith…

This study will test a new, non-invasive bedside scan (3D-EIT) to see if it can accurately diagnose and monitor pulmonary embolism (blood clots in the lungs) without using radiation. About 115 adults with and without clots will participate. The goal is to provide a safer, easier …

This study tests whether the blood thinner enoxaparin can prevent dangerous blood clots in teens who are critically ill in the intensive care unit. About 800 high-risk teens will receive either enoxaparin or a placebo. The goal is to see if the drug reduces clots without causing …

This study tests whether a higher dose of the blood thinner enoxaparin can better prevent dangerous blood clots in the legs or lungs of severely injured patients. About 540 adults in intensive care after trauma will receive either the standard or a double dose. The goal is to see…

This study tests a special care plan to help Chinese patients with advanced EGFR-mutated lung cancer who are taking the drug amivantamab. The plan focuses on preventing common side effects like blood clots, skin rashes, and infusion reactions. About 122 adults will join to see if…

This study tests whether watching a short, informative video before receiving a blood-thinner injection (LMWH) after childbirth can reduce anxiety and pain. 160 new mothers will be randomly assigned to get either the usual verbal explanation or the explanation plus the video. Res…

This observational study will track 87 people who are already scheduled to receive treatment with the Recana Thrombectomy Catheter System for blocked veins in their legs. The goal is to see how safe the device is and how well it works at clearing the blockages during the procedur…

This observational study will collect data from health records of 850 children under 2 years old who have venous thromboembolism (blood clots). The goal is to see how doctors prescribe rivaroxaban (Xarelto) and other standard blood thinners, and to track any serious bleeding. No …

This study tests a decision aid for people who have had a first blood clot and must decide whether to stop or continue blood thinners after at least 3 months of treatment. The aid provides balanced information on risks and benefits and helps clarify personal values. Researchers w…

This study looks at 1,300 people with moderate-risk pulmonary embolism (blood clots in the lungs) to compare three treatments: blood thinners, clot-busting drugs, and mechanical clot removal. Researchers will track deaths, heart recovery, bleeding risks, and quality of life over …

This study follows 150 adults with severe arm or leg injuries to see if developing a blood clot raises the risk of long-term pain. Participants are enrolled within 72 hours of hospital admission and monitored for six months. The goal is to understand how blood clots and pain are …

This study will see if using virtual care technologies in hospital units can reduce problems like patient falls, infections, and readmissions, while also improving patient satisfaction. About 10,000 adults admitted to six hospital units will take part, with three units using the …

This study looks at whether certain natural markers on red blood cells, called Lewis antigens, are more common in people who have had blood clots in their veins. Researchers will test 100 adults with a history of deep vein thrombosis and record their other clot risk factors. The …

This study looks at how the blood thinner enoxaparin works in critically ill ICU patients with kidney failure, some on dialysis and some not. Researchers will measure drug levels in the blood over 24 hours after a daily shot. The goal is to see if current dosing is enough to prev…
