Biogen Presents Optimistic Outcomes from Section 2 IGNAZ Examine of Felzartamab in IgA Nephropathy at American Society of Nephrology (ASN) Kidney Week 2024 By Investing.com

• The detailed examine outcomes confirmed interim findings, exhibiting secure kidney perform and sustained therapy impact greater than 18 months after the final dose of felzartamab
• Felzartamab, an investigational anti-CD38 monoclonal antibody, is a possible first-in-class therapeutic candidate for a spread of uncommon immune-mediated indications with planning underway for Section 3 growth
• IgA Nephropathy (IgAN) is a number one reason behind continual kidney illness with as much as 40% of IgAN sufferers progressing to finish stage kidney illness about 20 years after prognosis

CAMBRIDGE, Mass., Oct. 26, 2024 (GLOBE NEWSWIRE) — Biogen Inc. (Nasdaq: NASDAQ:) “ right this moment offered full outcomes from the Section 2 IGNAZ examine evaluating felzartamab, an investigational anti-CD38 monoclonal antibody, in folks dwelling with IgA nephropathy (IgAN). The outcomes confirmed substantial reductions in proteinuria, stabilization of kidney perform, and sustained therapy impact greater than 18 months after the final dose of felzartamab. The whole outcomes had been shared throughout an oral presentation at Kidney Week 2024, the American Society of Nephrology’s annual assembly, 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 suggest that felzartamab may have the potential to preserve kidney function and be administered on treatment cycles instead of continuous dosing.

Further analysis revealed that felzartamab administration resulted in selective and durable reductions in IgA antibody levels, while IgG and IgM levels recovered to baseline 3 months off-treatment. This selective reduction may offer maintenance of significant immune functions essential for infection protection. Overall, administration of felzartamab was generally well tolerated with a safety profile consistent with prior studies.

We are encouraged by the overall results of the IGNAZ study, especially given the significant unmet medical need for additional treatments to address high-risk IgA nephropathy, said Uptal Patel, M.D., Head of Development, HI-Bio at Biogen. We are grateful to all the participants, investigators and study staff who contributed to this study, whose findings will help us continue to evaluate felzartamab’s role in preserving kidney function as we plan for Phase 3.

About Felzartamab
Felzartamab is an investigational therapeutic human monoclonal antibody directed against CD38, a protein expressed on mature plasma cells. Felzartamab is a potential first-in-class therapeutic candidate with promise as a pipeline-in-a-product across a range of immune-mediated diseases. Felzartamab has been shown in clinical studies to selectively deplete CD38+ plasma cells, which may allow applications that ultimately improve clinical outcomes in a broad range of diseases driven by pathogenic antibodies. Felzartamab was originally developed by MorphoSys AG for multiple myeloma. Human Immunology Biosciences (HI-Bio) exclusively licensed the rights to develop and commercialize felzartamab across all indications in all countries and territories excluding China (including Macau and Hong Kong and Taiwan). Biogen acquired HI-Bio in July 2024.

Felzartamab is an investigational therapeutic candidate that has not yet been approved by any regulatory authority and its safety and effectiveness have not been established.

About IgA Nephropathy (IgAN)
Immunoglobulin A nephropathy (IgAN) is the most common primary glomerulonephritis worldwide. It is a leading cause of chronic kidney disease with up to 40% of IgAN patients progressing to end stage kidney disease about 20 years after diagnosis. IgAN accounts for about 40% of all native-kidney biopsies in Japan, 25% in Europe, 12% in the United States, but less than 5% in central Africa.¹
