LilleAges 18 years+ - NCT05288842Recruiting
Study spinal fluid and brain changes in dementia types
This study looks at spinal fluid and MRI results in people with Alzheimer’s disease, frontotemporal dementia, or normal thinking (controls). It aims to understand differences in brain-related cells and measure what might help explain or track these conditions.
LilleAges 40–85 - NCT05290363Recruiting
Studying a blood signal in active spondyloarthritis
This study looks at how a body signal called IL-23 may drive inflammation in spondyloarthritis (including joints) using samples from your care. It may help researchers identify which body cells and targets are involved, and how treatments could work better for active disease.
CréteilAges 18 years+ - NCT05298722Recruiting
MRI and blood tests to predict if pancreatic surgery is possible
This study looks at MRI scans, computer-extracted imaging features, and blood/“liquid biopsy” tests after FOLFIRINOX chemotherapy to predict whether surgery can fully remove pancreatic cancer. It may help your care team choose the best next step—whether surgery is likely to be possible and how to plan it.
Ghent, East FlandersAges 18 years+ - NCT05303337Recruiting
Study of gut and HIV changes after switching to long-acting shots
This trial compares how HIV “reservoirs,” inflammation, and the gut microbiome change when people switch from daily HIV pills to long-acting injectable treatment. It may help you and your team understand what to expect with the switch and how your body responds.
