Immunoglobulin A vasculitis

Researchers are testing whether regularly checking a marker called Gd-IgA1 can help doctors adjust treatment for IgA nephropathy, a kidney disease. Adults with biopsy-confirmed IgA nephropathy or IgA vasculitis-associated nephritis receive Nefecon or telitacicept. Half have Gd-Ig…

This study tests three standard medications—colchicine, dapsone, and azathioprine—in 90 people with isolated skin vasculitis (inflammation of small or medium blood vessels in the skin). Participants are randomly assigned to one of the drugs, and doctors track how well the skin re…

This study tests a new drug, BBD-1, against standard steroids for IgA vasculitis, a disease that causes purple spots on the skin, joint pain, and can damage the kidneys. The trial will enroll 30 adults with confirmed IgA vasculitis. The goal is to see if BBD-1 can clear skin spot…

This study tests a drug called ravulizumab in children aged 2 to 18 with a kidney disease called IgA nephropathy. The goal is to see if the drug can reduce protein in the urine, a sign of kidney damage. Participants will receive the drug through an IV and be monitored for safety …

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 an oral drug called sparsentan in 67 children with certain kidney diseases that cause protein to leak into urine. The goal is to see if the drug safely reduces protein levels over 108 weeks. Participants must have a certain level of kidney function to join.

This study tests whether adding finerenone to standard blood pressure medication (ACEI/ARB) can better reduce protein in the urine of children with Henoch-Schönlein purpura nephritis and mild proteinuria. About 116 children aged 3 to 17 will take either finerenone plus ACEI/ARB o…

This study looks at whether a protein in the blood, called I-FABP, can tell doctors if a child's IgA vasculitis is affecting their stomach or intestines. Researchers will take blood samples from 100 children at diagnosis and again 2-4 weeks later. If I-FABP levels are linked to g…

This study tracks the pregnancy experiences of women with vasculitis, a group of rare diseases causing blood vessel inflammation. Researchers will use online surveys to understand how vasculitis affects pregnancy and what outcomes occur. The goal is to gather information to help …

This study collects tissue samples from 1,000 people with various forms of vasculitis, a group of rare inflammatory blood vessel diseases. Researchers will analyze the samples alongside clinical data to identify genes that increase risk and to spark new ideas for diagnosis and tr…

This study looks at skin samples from 50 people with different types of vasculitis, a condition where blood vessels become inflamed. Researchers want to understand how the disease affects the skin at a molecular level. Participants must have an active skin rash related to their v…

This study looks at blood and kidney tissue from 150 adults with IgA nephropathy or related kidney diseases. Researchers want to find unique patterns in immune cells that cause kidney damage. The goal is to develop a blood test that could diagnose the disease without a painful ki…
