Otsuka announces FDA acceptance and priority review of biologics license application for sibeprenlimab in the treatment of immunoglobulin A nephropathy
26 May 2025 - Otsuka Pharmaceutical today announce the US FDA has accepted for review the biologics license application for sibeprenlimab, an investigational monoclonal antibody that selectively inhibits the activity of APRIL (A PRoliferation-Inducing Ligand) in adults with immunoglobulin A nephropathy (IgAN).
APRIL plays a key role in the pathogenesis of IgAN as explained by the 4-hit process, in which pathogenic galactose-deficient IgA (Gd-IgA1) is produced, leading to the synthesis of autoantibodies against Gd-IgA1, immune complex formation, and deposition in the glomerular mesangium.
