Milan, ItalyAges 18 years+ - NCT06718894Recruiting
New treatment strategy for primary podocytopathies
This trial is testing a new treatment approach for people with certain kidney diseases called podocytopathies (like FSGS and MCD). It may help if you have active disease, even after a kidney transplant, or if you have another type of kidney inflammation.
MilanAges Any age - NCT00899626Recruiting
Collecting stool and tissue markers from people with bowel conditions
This study collects samples (like tissue and other body fluids) from people who are getting a colonoscopy or similar camera test. It aims to find “biomarkers,” which are measurable signals that may help doctors better understand or detect bowel problems such as colorectal cancer, polyps, or inflammatory bowel disease.
Nashville, TennesseeAges 18 years+ - NCT04458792Recruiting
Builds a cancer blood-and-biomarker database after sarcoma treatment
This study collects information and blood samples from adults with sarcoma who had surgery and possibly radiation. The goal is to build a large dataset that helps researchers understand sarcoma better and improve future care.
Montpellier, HeraultAges 18 years+ - NCT05089162Recruiting
Testing a heart ultrasound approach in chronic heart failure
This study looks at people with chronic heart failure with weaker pumping function and checks how well a lung/heart ultrasound can assess congestion (fluid buildup). If you qualify, you may help test a better way to evaluate your condition during a planned hospital visit.
Vandœuvre-lès-NancyAges 18 years+ - NCT05089149Recruiting
Check how lung ultrasound helps manage heart failure congestion
This study looks at people with long-term worsening heart failure who are coming to the hospital for a planned visit, to see how checking “congestion” (fluid buildup) may guide care. It may help the team understand whether lung ultrasound can better assess who needs treatment changes.
