(Nasdaq: BIIB) – today presented complete results from the Phase 2 IGNAZ study evaluating felzartamab, an investigational anti-CD38 monoclonal antibody, in people living with IgA nephropathy (IgAN). The results showed substantial reductions in proteinuria, stabilization of kidney function, and sustained treatment effect more than 18 months after the last dose of felzartamab. The complete results were shared during an oral presentation at Kidney Week 2024, the American Society of Nephrology’s annual meeting, in San Diego, California. \"The complete results of the IGNAZ Study reaffirm our interim findings, showing a reduction in proteinuria, stabilization of kidney function, and sustained treatment effect more than 18 months after the last dose of felzartamab,” said Jonathan Barratt, MD, PhD, FRCP, Mayer Professor of Renal Medicine at the University of Leicester. “This is promising news for patients and supports the potential of felzartamab to be a meaningful treatment option for people living with IgA nephropathy, a leading cause of chronic kidney disease.” The Phase 2 IGNAZ study (n=54) explored the efficacy and safety of felzartamab in patients with IgAN and high risk of progressive kidney dysfunction. With respect to efficacy, patients receiving a nine-dose regimen of felzartamab over a six-month treatment period experienced substantial reductions in proteinuria levels as assessed by the urinary protein:creatinine ratio (UPCR) and stabilization of kidney function, as measured by the estimated glomerular filtration rate (eGFR), through 24 months. Notably, patients maintained a mean reduction of approximately 50% in the UPCR through month 24, which was more than 18 months after the last dose was administered. These results su...
