Anticoagulation plus tocilizumab for cerebral venous thrombosis
This trial tests a combination of blood thinners (anticoagulation) and a drug called tocilizumab, which targets inflammation, to treat acute cerebral venous thrombosis (a blood clot in a vein in the brain). It aims to see if this combined treatment improves recovery and reduces complications compared to blood thinners alone.

Telerehabilitation for arm function after stroke
This study compares two levels of therapist-guided home exercises delivered via video calls to improve arm and hand function after a stroke. It may help you recover more movement in your affected arm.
IslamabadAges 40–70 - NCT07807046Recruiting
Guided atracurium dosing in ICU patients
This trial tests whether using a device to guide the dosing of atracurium (a muscle relaxant) improves outcomes in critically ill ICU patients who need this medication for more than 48 hours. It focuses on patients with severe lung or heart conditions, such as ARDS or ECMO support.
New Taipei CityAges 20 years+ - NCT07805616Recruiting
New risk categories for blood clots in the lungs
This study looks at whether a new way of grouping patients with blood clots in the lungs (pulmonary embolism) can better predict their outcomes. If you join, your health will be tracked for 30 days to see how well this new system works.
IstanbulAges 18 years+ - NCT07808749Recruiting
Monitoring blood flow during lung surgery
This study looks at how your heart and lungs work together during lung surgery using small incisions. By monitoring blood flow in a neck artery, doctors hope to improve safety during the operation.
ValenciaAges Any age - NCT07803016Recruiting
Drawing exercises vs fine motor training for hand recovery after stroke
This trial compares two types of hand exercises to see which one helps you regain hand movement and control better after a stroke. It focuses on people in the sub-acute phase (early recovery) who have some voluntary hand movement.
IslamabadAges 40–70 - NCT07806097Recruiting
Self-directed arm gaming during stroke rehab
This trial tests whether playing arm-focused video games on your own helps improve arm movement while you're in the hospital for stroke rehabilitation. You would play games that involve moving your arm and hand, and the goal is to see if this makes your recovery better.
Chicago, IllinoisAges 18 years+ - NCT07804706Recruiting
Blood test and heart response before cancer surgery
This study looks at whether a simple blood test and how your heart responds during anesthesia can predict complications after major cancer surgery. It may help doctors better prepare patients for surgery.
Ankara, Yeni̇mahalleAges 18 years+ - NCT07806890Recruiting
New 4D ultrasound imaging during left atrial appendage closure
This study tests a new 3D/4D ultrasound technology that creates detailed images of the heart during a left atrial appendage closure procedure. The goal is to see if this imaging tool helps doctors perform the procedure more safely and accurately.
Cleveland, OhioAges 18 years+ - NCT07805564Recruiting
Ultrasound score to predict kidney injury after heart surgery
This study tests whether an ultrasound score (VExUS) can predict kidney injury after open-heart surgery. It may help doctors adjust care to protect your kidneys.
Hanoi, HanoiAges 18 years+ - NCT07806370Recruiting
Balloon vs. Stent for Heart Attack Patients with High Clot Burden
This study compares two treatments for heart attack patients with a large blood clot in the blocked artery: a drug-coated balloon versus a drug-eluting stent. The goal is to see which approach better prevents slow blood flow or no reflow right after the procedure.
Xi'an, ShaanxiAges 18–75 - NCT07803029Recruiting
Measuring fluid changes during dialysis
This study uses a special device to measure fluid levels in the body during dialysis. It may help doctors better understand and manage fluid balance for people on hemodialysis.
Aarhus, Central DenmarkAges 18 years+ - NCT07804420Recruiting
Personalized blood pressure prevention for high-risk adults
This study tests a program that uses a health app to estimate your risk of developing high blood pressure and then gives personalized advice to help lower that risk. You must live in Shunyi District, be between 35 and 65, and not have high blood pressure currently.
Beijing, Beijing MunicipalityAges 35–65 - NCT06471621Recruiting
Personalized care to prevent kidney injury after heart surgery
This trial tests whether personalized care can prevent acute kidney injury (sudden kidney damage) after heart or major blood vessel surgery. If you are having planned heart valve repair, bypass, or aortic surgery, you may be able to join.
BernAges 18 years+ - NCT06515262Recruiting
Testing anti-BCMA-GPRC5D CAR-T cells for relapsed multiple myeloma
This trial tests a new type of cell therapy (CAR-T cells) that targets two proteins, BCMA and GPRC5D, on myeloma cells. It aims to see if it is safe and effective for people whose multiple myeloma has come back or stopped responding to at least three previous treatments.
