Paris, Île-de-France RegionAges 18–49 - NCT07071649Recruiting
Blood test for Alzheimer's compared with spinal fluid test
This study is testing a simple blood test (p-Tau217) as a possible way to diagnose Alzheimer's disease. If it works, it might replace the need for a spinal tap. The results will be compared with the usual spinal fluid markers.
AmiensAges 18 years+ - NCT03773887Recruiting
Study of liver inflammation and healing in alcohol-related liver disease
This study compares patterns of liver inflammation and the liver’s healing ability in people with alcohol-related liver disease, using blood tests and (in most cases) a liver tissue sample. It may help doctors better understand what is happening in the liver and how it may recover.
LilleAges 18–70 - NCT04163614Recruiting
Testing blood pressure patterns and fluid removal during dialysis
This study looks at how blood pressure changes during hemodialysis and how much fluid is removed, to see what approach works best for controlling blood pressure. It may help dialysis patients whose blood pressure is often high before or after treatment.
Dallas, TexasAges 18 years+ - NCT03595267Recruiting
Kidney health checks and care for Indigenous communities
This study offers kidney-related health screening and follow-up care for people in Indigenous communities. It’s designed to help check kidney health early using simple health measurements, and may help you get guidance sooner if anything looks off.
Calgary, AlbertaAges 10–80 - NCT04711551Recruiting
Monitoring patients after regenerative treatments for joint or tendon pain
This trial follows people who receive “regenerative medicine” treatments (orthobiologics) for joint or tendon problems, like osteoarthritis or tendon pain. The goal is to study whether clinical check-ins and lab/biologic measurements can help monitor how patients are doing after treatment.
Milan, ItaliaAges 6 years+ - NCT05711173Recruiting
Study blood clot triggers and immune cell changes in clot patients
This study looks at how certain blood cell changes and immune system activity may relate to blood clots in specific veins or lungs. It may help researchers understand why clots happen “without a clear cause” and how to better predict risk.
BordeauxAges 6–50 - NCT06324149Recruiting
Frailty and aging conditions in chronic diseases
This study looks at how frailty affects the course of chronic diseases and how chronic diseases affect frailty. It may help understand aging-related conditions better.
