Vera Therapeutics Inc. announced positive results from the ORIGIN Phase 3 trial of atacicept in IgA nephropathy (IgAN). The data were presented as a late-breaking oral presentation during the opening plenary session of the American Society of Nephrology (ASN) Kidney Week 2025 and simultaneously published in The New England Journal of Medicine. Atacicept met its primary endpoint, demonstrating a 46% reduction in proteinuria from baseline and a 42% reduction compared to placebo at week 36 (p<0.0001). The safety profile of atacicept was reported to be favorable and comparable to placebo. Vera Therapeutics plans to submit a Biologics License Application (BLA) to the U.S. Food and Drug Administration through the Accelerated Approval Program in the fourth quarter of 2025, with a potential PDUFA date in 2026. The ORIGIN 3 trial is ongoing, with two-year results expected in 2027.
