TL;DR
Novartis has received FDA traditional approval for Fabhalta® (iptacopan), making it the first complement inhibitor approved to slow kidney function decline in IgA nephropathy. This marks a significant milestone in kidney disease treatment.
Novartis announced that its drug Fabhalta® (iptacopan) has received FDA traditional approval, becoming the first medication of its kind to demonstrate a significant slowdown in kidney function decline in patients with primary IgA nephropathy (IgAN). This approval marks a key milestone in the treatment of this chronic kidney disease, offering new hope for patients and clinicians.
The FDA granted traditional approval based on clinical trial data showing that Fabhalta® (iptacopan) effectively reduces the rate of kidney function decline in primary IgA nephropathy, a rare and progressive kidney disorder. The approval makes it the only complement inhibitor with this specific indication, according to Novartis.
Developed by Novartis, Fabhalta® (iptacopan) is a complement pathway inhibitor that targets the alternative pathway, which plays a role in the immune response associated with IgA nephropathy. The drug was evaluated through a comprehensive review process, including data from pivotal phase 3 trials, which demonstrated its efficacy and safety profile.
Officials from Novartis highlighted that this approval addresses an unmet medical need, as current treatments for IgAN are limited and primarily focus on managing symptoms rather than slowing disease progression. The company plans to launch the drug globally, starting with the U.S., where the approval was granted.
Impact of FDA Approval on IgA Nephropathy Treatment Landscape
This approval is significant because it introduces the first targeted therapy proven to slow the progression of IgA nephropathy, a disease that can lead to kidney failure. It provides clinicians with a new, evidence-based option to manage a condition that previously had limited treatment options.
The approval could also influence future drug development and regulatory pathways for kidney diseases, emphasizing the importance of complement pathway inhibitors in nephrology. Patients who previously had few options now have access to a therapy that may alter the disease course.

Background on IgA Nephropathy and Treatment Advances
IgA nephropathy is a leading cause of primary glomerulonephritis and can progress to end-stage kidney disease. Traditionally, treatment has focused on controlling blood pressure and reducing proteinuria, with no approved therapies specifically targeting disease progression until now.
Previous research indicated that the complement system, particularly the alternative pathway, plays a role in the disease’s pathology. This led to the development of complement inhibitors like Fabhalta® (iptacopan), which have shown promise in clinical trials.
In 2022, Novartis reported positive results from phase 3 trials of Fabhalta®, paving the way for regulatory review and eventual approval. The drug’s approval by the FDA marks a milestone following these developments.
„This approval represents a breakthrough in the treatment of IgA nephropathy, offering hope to patients with limited options and addressing an unmet medical need.“
