Sparsentan

CSL Vifor and Travere Therapeutics announce European Commission approves FILSPARI(sparsentan) for the treatment of IgA Nephropathy (IgAN). First non-immunosuppressive therapy for the treatment of IgAN approved in Europe.
Sparsentan is a novel, non-immunosuppressive, single-molecule, dual endothelin angiotensin receptor antagonist with high selectivity for the endothelin A receptor (ETAR) and the angiotensin II subtype 1 receptor (AT1R). Pre-clinical data have shown that blockade of both endothelin type A and angiotensin II type 1 pathways in forms of rare chronic kidney disease, protects podocytes, prevents glomerulosclerosis and mesangial cell proliferation, and reduces proteinuria.
