argenx Presents New Data at AANEM and MGFA Scientific Session Showcasing Earlier and Sustained Treatment in MG and CIDP with VYVGART and Progress Across its Neuromuscular Pipeline

argenx presented new clinical data at the AANEM and MGFA scientific sessions demonstrating deepening improvements in ocular myasthenia gravis (MG) with VYVGART, sustained one-year efficacy in anti-AChR antibody-negative MG patients, and benefits of earlier treatment initiation. Real-world evidence from over 1,100 U.S. MG patients showed greater clinical gains when treatment started within one year of diagnosis. Long-term CIDP data reinforced consistent safety and efficacy, with a Phase 4 study supporting direct transition from IVIg. Pipeline candidates empasiprubart and adimanebart showed promising Phase 2 results in multifocal motor neuropathy and congenital myasthenic syndrome respectively.
