Sibeprenlimab (VOYXACT®; sibeprenlimab-szsi) is a fully humanized monoclonal antibody that binds to A PRoliferation Inducing Ligand (APRIL) being developed by Otsuka Pharmaceutical for the treatment of immunoglobulin A (IgA) nephropathy and Sjögren's disease. Signalling via APRIL is implicated in the inflammatory processes that ultimately result in damage to the glomeruli in patients with IgA nephropathy. Treatment with sibeprenlimab suppressed APRIL levels and reduced proteinuria in patients with IgA nephropathy, according to interim analyses from the ongoing VISIONARY phase III clinical trial. This article summarizes the milestones in the development of sibeprenlimab leading to this first approval to reduce proteinuria in adults with primary IgA nephropathy at risk for disease progression.
