First-line and Second-line Therapy of Zuberitamab in Idiopathic Membranous Nephropathy: A Single-center Retrospective Study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Rationale & Objective: Idiopathic membranous nephropathy (IMN) is a major cause of nephrotic syndrome. Although rituximab has improved outcomes, resistance or intolerance occurs in a subset of patients. Zuberitamab, a chimeric anti-CD20 immunoglobulin G1 monoclonal antibody, may offer an alternative therapeutic option. This study aimed to evaluate the effectiveness and safety of zuberitamab in patients with phospholipase A2 receptor (PLA2R)-associated IMN. Study Design: Single-center, retrospective observational cohort study. Setting & Participants: Sixty patients with biopsy-proven or serologically diagnosed PLA2R-associated IMN were treated with zuberitamab at Henan Provincial People's Hospital between July 2023 and June 2024. Thirty-five received zuberitamab as first-line therapy; 25 received it as second-line therapy following prior immunosuppressive treatment. Interventions: Zuberitamab infusions administered in 2-3 doses over several months, guided by B-cell kinetics. Outcomes: The primary outcome was complete or partial remission of proteinuria at 3 and 6 months. Secondary outcomes included changes in serum albumin, serum creatinine, estimated glomerular filtration rate, CD19+ B cells, and anti-PLA2R antibody titers. Results: At month 3, 80% (48/60) of patients achieved remission (5 complete and 43 partial). By month 6, 13 patients achieved complete remission (11 first line and 2 second line; Limitations: Single-center, retrospective design; short follow-up; no direct comparator group; incomplete biomarker data owing to testing limitations. Conclusions: Zuberitamab was associated with favorable clinical and immunologic responses in patients with IMN, including those previously treated with rituximab. These findings support its potential role as a therapeutic option, warranting further validation in prospective studies.
