LinzAges 18 years+ - NCT07181941RecruitingPhase 1/Phase 2
Testing lower doses of linvoseltamab for multiple myeloma
This trial tests if a lower dose of linvoseltamab can still work well for people with multiple myeloma that has come back or not responded to treatment. It aims to reduce side effects while keeping the cancer under control.
Seattle, WashingtonAges 18 years+ - NCT07182955Recruiting
Exercise training for chest pain with clear arteries
This research study looks at why people with chest pain but clear heart arteries have low fitness. It tests whether a home-based interval training program (short bursts of hard exercise) can improve fitness and quality of life.
Charlottesville, VirginiaAges 18–85 - NCT07183605Recruiting
How different ways of drawing blood from a central line compare for heparin activity
This trial checks whether blood samples taken from a central line using either a syringe flush or a vacuum tube give the same heparin activity results as blood from a vein in the arm. It is designed for patients in the ICU who are on a steady heparin drip.
OrléansAges 18 years+ - NCT07184476Recruiting
Measuring small blood vessels in kids having heart surgery
This study looks at tiny blood vessels in children with specific heart defects during surgery. It may help doctors better understand circulation and improve care.
Boston, MassachusettsAges 1 day–17 years - NCT07184541Recruiting
Nurse-led weight monitoring for heart failure quality of life
This study tests a nurse-led program where you weigh yourself daily at home to help manage your heart failure. It aims to improve your quality of life and your ability to care for yourself.
Avon, OhioAges 55 years+ - NCT07184723Recruiting
How doctors treat abdominal aortic aneurysms in Europe
This trial looks at how doctors manage a specific type of enlarged artery in the belly that hasn't burst but is causing symptoms. The goal is to understand current treatment patterns across Europe.
Vienna, State of ViennaAges 18 years+ - NCT07184892Recruiting
Swallowing therapy after stroke
This study tests if watching swallowing movements (action observation therapy) helps people recover swallowing function after a first-time stroke. It uses a brain imaging technique called fNIRS to see how the brain responds.
Jinan, ShandongAges 18–80 - NCT07185022Recruiting
Clot-busting drug through artery for medium-vessel stroke
This trial tests a clot-busting drug given directly into the arteries of the brain for people who have had a stroke due to a blockage in a medium-sized artery. It aims to see if this treatment can help improve recovery when started up to 72 hours after symptoms begin.
Fuyang, AnhuiAges 18 years+ - NCT07185100Recruiting
Finding early heart failure in at-risk adults across Germany
This study uses heart MRI scans to find unrecognized heart failure in people who have risk factors like diabetes, kidney disease, high blood pressure, or obesity but haven't been diagnosed with heart failure yet. If you join, you will help researchers learn how common hidden heart failure is and take an important step for your own heart health.
BerlinAges 40–69 - NCT07187206RecruitingPhase 3
Fetoscopic surgery for severe diaphragmatic hernia
This trial tests if a special surgery (FETO) done while the baby is still in the womb can improve survival for babies with a severe form of congenital diaphragmatic hernia (CDH). The surgery places a small balloon in the baby's windpipe to help the lungs grow. We are looking for pregnant women whose baby has a left-sided CDH with a lung-to-head ratio (LHR) less than 30%, or a right-sided CDH with LHR less than 45%, and whose liver is herniated into the chest.
Cincinnati, OhioAges 18–50 - NCT07187440Recruiting
Study of Fabry disease treatment in Chinese children and adults
This study tests an enzyme replacement therapy (agalsidase alfa) for Fabry disease in Chinese children and adults. It's an observational study that follows patients who receive the treatment as part of their regular care.
Hefei, AnhuiAges 7 years+ - NCT07187570RecruitingPhase 3
Dapagliflozin to prevent atrial fibrillation recurrence after cardioversion
This trial tests if the diabetes drug dapagliflozin can lower the chance of atrial fibrillation (an irregular heartbeat) coming back after a procedure called electrical cardioversion, which uses a shock to restore a normal heart rhythm. If you have AF and are scheduled for cardioversion, you may be able to join.
LinköpingAges 55 years+ - NCT07187830Recruiting
Semaglutide for belly fat and liver health in kidney disease
