Idiopathic nephrotic syndrome

This Phase 2 study tests atacicept, a drug that may reduce immune system attacks on the kidneys. About 250 adults with various autoimmune kidney diseases (like IgA nephropathy or membranous nephropathy) will receive weekly injections. Researchers will check safety and measure cha…

This study tests a new treatment called QT-219CX, which uses specially engineered immune cells (CAR-T cells) to target and calm the overactive immune system in people with autoimmune diseases like lupus, kidney disease, and scleroderma. The treatment is given as a one-time infusi…

This early-phase trial is testing a new type of cell therapy called QT-219C, which uses donor-derived CAR-T cells to target and destroy faulty immune cells in people with severe autoimmune diseases like lupus, nephrotic syndrome, and vasculitis. The study will enroll 15 participa…

This early-stage study is testing a universal donor CAR T-cell therapy that targets two proteins (CD19 and BCMA) on immune cells that drive autoimmune diseases. The goal is to see if it is safe and can help control conditions like lupus, kidney disease, and vasculitis. About 15 p…

This study tests if dupilumab, a drug already used for allergies, can help children with severe nephrotic syndrome stay relapse-free longer. About 66 kids aged 6–18 will get either dupilumab or a placebo injection for 6 months, while slowly reducing their steroid dose. The goal i…

This early-phase trial is testing a new type of cell therapy (CAR-NK cells) in 36 children with B-cell-related autoimmune diseases like lupus and certain kidney diseases. The therapy uses specially designed immune cells to target and potentially control the overactive immune syst…

This study is collecting blood, urine, and kidney tissue samples from 144 children and adults with a kidney condition called nephrotic syndrome. The goal is to build a large database and sample collection to study how the immune system and kidney cells interact. Researchers hope …

This study helps people with certain kidney diseases (like nephrotic syndrome and FSGS) find clinical trials that match their specific disease profile. Researchers analyze participants' molecular data to recommend targeted therapies in ongoing trials. The goal is to improve treat…

This study is investigating whether certain autoantibodies, especially those targeting a protein called nephrin, play a role in nephrotic syndrome, a kidney condition that causes swelling and protein loss in urine. Researchers will analyze blood and kidney tissue from 50 children…

This study follows up to 1,180 children in France with a rare kidney condition called idiopathic nephrotic syndrome. Researchers will collect information on disease patterns, treatments, and side effects to build a detailed database. The goal is to better understand the disease a…

This study examines 30 adults with idiopathic nephrotic syndrome, a kidney condition that can lead to kidney failure. Researchers will analyze blood immune cells and bacteria from stool and urine samples to see if changes in gut or urinary bacteria are linked to immune system pro…

This registry is gathering health information and biological samples from 500 people with focal segmental glomerulosclerosis (FSGS) or minimal change disease (MCD), two rare kidney conditions. Researchers will track participants over 10 years to understand how these diseases prog…
