A Phase 2, Open-Label Study to Evaluate the Safety and Efficacy of Budoprutug (TNT119) in Subjects With Primary Membranous Nephropathy (PMN)

Budoprutug is a humanized, immunoglobulin (Ig) G1 monoclonal antibody that selectively binds to CD19 and is projected to deplete targeted cells through antibody-dependent cellular cytotoxicity (ADCC). This Phase 2, open-label, multicenter study evaluates the safety, pharmacodynamics, and preliminary efficacy of three intravenous dose regimens of budoprutug in adult subjects with primary membranous nephropathy (PMN) who are anti-PLA2R antibody positive and have persistent proteinuria despite optimized RAAS inhibition. Approximately 45 subjects will be enrolled across three sequential dose cohor…
