Medical Use

FILSPARI is a dual antagonist for endothelin and angiotensin II receptors, prescribed to reduce proteinuria in adults with primary immunoglobulin A nephropathy (IgAN) who are at risk of rapid disease progression. This typically includes patients with a urine protein-to-creatinine ratio (UPCR) of ≥1.5 g/g. It’s important to note that this indication is granted under accelerated approval based on the reduction of proteinuria, and it has not yet been confirmed whether FILSPARI slows the decline in kidney function in IgAN patients. Continued approval may depend on the results of a confirmatory clinical trial.
