New study observes Real-World progress of kidney disease treatment
NCT ID NCT06242327
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This observational study follows 500 adults with primary membranous nephropathy and nephrotic syndrome who are treated with rituximab or other monoclonal antibodies. Researchers aim to describe long-term disease outcomes and identify predictors of remission or progression. The study does not test a new treatment but gathers real-world data to improve understanding of current therapies.
