Immunoglobulin A Nephropathy – Current Treatment – Treatment Algorithms: Claims Data Analysis – IgA Nephropathy (US)
IgA nephropathy (IgAN), also known as Berger’s disease, is a rare autoimmune condition that causes the accumulation of IgA in the kidney glomeruli, causing inflammation and damage to the kidneys. Initial treatment of IgAN predominantly comprises supportive care using RAAS inhibitors, SGLT-2 inhibitors, immunosuppressants, and/or diuretics. The FDA’s acceptance of the surrogate clinical trial endpoint “reduction in proteinuria” has enabled accelerated approval of novel IgAN therapies, leading to early market entries and the potential for rapid evolution of the therapeutic landscape. Under this scheme, the FDA approved Calliditas Therapeutics’ Tarpeyo (DR-budesonide), Travere Therapeutics’ Filspari (sparsentan), and Novartis’s Fabhalta (iptacopan). Tarpeyo and Filspari are now fully approved therapies in the United States. This report examines how the established and newly launched immunosuppressive and non-immunosuppressive therapies are being used to treat newly diagnosed and recently treated IgAN patients.
Questions answered

- How has Filspari been integrated into the treatment algorithm, and what is its source of business?
- What percentage of IgAN patients receive drug therapy within one year of diagnosis, and how quickly? What percentage of patients progress to later lines of therapy within one year of diagnosis?
- What percentage of IgAN patients are treated with monotherapy vs. combination therapy? What are the most commonly used combinations?
