Exosomes for Sjogren's and Dry Eye
This study looks at tiny particles called exosomes in tears to find new ways to diagnose or treat Sjogren's syndrome and dry eye disease. It may help people with these conditions by learning more about what causes them.
Taipei, TaiwanAges 20–75 - NCT07473154RecruitingPhase 1/Phase 2
Calming an overactive immune system with special cells
This trial tests a new type of cell therapy made from a patient's own white blood cells (called lymphocytes) that are designed to help control the immune system. The goal is to reduce inflammation and symptoms in people with hard-to-treat rheumatoid arthritis or a severe form of scleroderma (dcSSc).
DüsseldorfAges 18 years+ - NCT07479433Recruiting
New approach to plan stent placement using CT scans
This study tests if using a special CT scan analysis can help doctors plan where to place stents for blocked arteries. It might make the procedure safer and more effective for people who are scheduled for a planned stent procedure.
Marietta, GeorgiaAges 18 years+ - NCT06781242Recruiting
Genes and symptoms in inherited bile flow problems
This study looks at how genes affect bile flow problems in the liver. If you have a rare genetic condition like PFIC, researchers want to understand your specific type better by comparing your genes to your symptoms.

Hairy cell leukemia disease burden study
This study watches the course of hairy cell leukemia (HCL) in different phases—when first diagnosed, after it comes back, or long after successful treatment. The goal is to better understand the disease and plan future care.
Bologna, BolognaAges 18 years+ - NCT07480057Recruiting
Bone health changes after liver transplant
This study tracks how liver transplantation affects your bone density and mineral metabolism. It aims to find changes early, which can help prevent fractures later.
