Stenting plus medication to prevent stroke from narrowed brain arteries
This trial tests whether placing a stent in a severely narrowed brain artery, along with aggressive medication, can prevent another stroke better than medication alone. It is for people who had a mild stroke within the last 30 days due to a 70-99% blockage in a major brain artery.
Beijing, Beijing MunicipalityAges 18–85 - NCT04973423Recruiting
Testing extra check-ins for Crohn’s using stool tests and MRI
This study checks whether adding an extra, cross-body “transmural” evaluation (looking at inflammation throughout the bowel) improves care for adults with Crohn’s who are starting or receiving biologic (biotherapy) treatment. It uses close follow-up with stool calprotectin (a marker of gut inflammation) to see if this approach helps control inflammation.
AmiensAges 18 years+ - NCT03810794Recruiting
Acupuncture study for people with Alzheimer’s memory problems
This trial tests whether acupuncture can improve symptoms in people with Alzheimer’s disease. You may qualify if you have memory and thinking changes consistent with Alzheimer’s and meet imaging and brain-scan score requirements.
Shanghai, Shanghai MunicipalityAges 50–85 - NCT04888364Recruiting
French study following people with Parkinson’s and related conditions
This study follows people with Parkinson’s disease, certain Parkinson-like conditions, and some people at higher risk. It helps researchers learn how these illnesses start and progress, which may lead to better earlier detection and care.
ParisAges 10 years+ - NCT04873258Recruiting
Test a non-invasive tool to screen for fat-related liver disease
This study looks at a new non-invasive screening method to predict metabolic dysfunction–associated steatotic liver disease (MASLD), a condition where fat builds up in the liver. The goal is to help identify people who may be at risk without needing invasive tests.
