IgA nephropathy affects 25-50 per million annually, with 20–40% progressing to end-stage kidney disease. Diagnosed cases in the US are expected to reach 135,000 by 2030. Treatments include ACE inhibitors, ARBs, corticosteroids, and immunosuppressants. FDA-approved treatments are TARPEYO, FILSPARI, and FABHALTA. The IgA nephropathy market is projected to reach ~USD 4.1 billion by 2034, driven by novel therapies like Novartis’ Atrasentan, Otsuka/Visterra’s Sibeprenlimab, Vertex/Alpine’s Povetacicept, and others.
