ABSTRACT
To observe the efficacy and safety of Ripertamab in the treatment of Idiopathic Membranous Nephropathy (IMN). Clinical data from patients with IMN treated with Ripertamab or Rituximab were retrospectively collected from six tertiary hospitals in Jilin Province between January and December 2023. Patients were grouped based on treatment regimen into the Ripertamab and Rituximab groups and matched 1:1 by age and gender. Follow-ups were conducted over six months to assess baseline characteristics, laboratory parameters, and adverse reactions related to anti-CD20 monoclonal antibody therapy. A total of 112 patients with IMN were identified, including 52 treated with Ripertamab and 60 with Rituximab. After matching, 40 patients were included in each group. Baseline clinical characteristics were comparable between the groups (P > 0.05). There was no statistically significant difference in efficacy between the two groups (P > 0.05). At 6 months, the overall effectiveness rate of Ripertamab in the treatment of IMN was 65.0%, of which the partial and complete remission rates were 50.0% and 15.0%, respectively. The overall effectiveness rate of Rituximab was 60.0%, of which the partial and complete remission rates were 47.5% and 12.5%, respectively. Similarly, there were no significant differences in the incidence of infusion reactions, pulmonary infections, interstitial lung disease, HBV reactivation, neutropenia, or thrombocytopenia (P > 0.05). Ripertamab demonstrates a therapeutic efficacy comparable to Rituximab for IMN, with a similar incidence of infusion-related adverse reactions and complications.
