Efficacy and safety of zuberitamab in the treatment of primary membranous nephropathy: an observational study

Research Background B lymphocyte-mediated adaptive immunity is pivotal in the pathogenesis of membranous nephropathy (MN). This study evaluated the efficacy and safety of zuberitamab, a novel anti-CD20 monoclonal antibody, in primary membranous nephropathy (PMN). Research Methods We retrospectively analyzed 25 patients with PMN treated with zuberitamab (zuberitamab group). Using 1:1 propensity score matching, we selected a comparable control cohort of 25 PMN patients who received rituximab during the same period (RTX group). The primary endpoint was the 12-month overall remission rate (CR + PR). Research Results All 25 patients (100.0%) in the zuberitamab group achieved clinical remission (CR 80.0%) at 12-month, with 11 patients achieving complete immunological remission. Compared to the RTX group, the complete remission (CR) rate was significantly higher (80.0% vs 32.0%, P
