GENEVA, June 26, 2026
New analyses from the Phase 3 Vivacity-MG3 study support the impact of IMAAVY in anti-AChR+a, anti-MuSK+b adult patients with generalized myasthenia gravis (gMG) including those early in their disease, participants with lower symptom burden and those who experienced common infectionsTo address an important evidence gap, the PETUNIAc study design will be presented – demonstrating the innovative way pregnancy outcomes data will be collected following treatment with IMAAVY IMAAVY, an immunoselective neonatal Fc receptor (FcRn) blocker, is designed to target and reduce pathogenic immunoglobulin G (IgG) autoantibodies associated with generalized myasthenia gravis (gMG)GENEVA, June 26, 2026 /PRNewswire/ -- Johnson & Johnson (NYSE: JNJ) today announced new data across 12 abstracts at the European Academy of Neurology (EAN) 2026 Congress that offer additional insight into the use of IMAAVY® (nipocalimab-aahu) throughout clinically relevant points in the generalized myasthenia gravis (gMG) treatment journey. The analyses include adults with anti-AChRa or anti-MuSKb antibody-positive gMG who were early in their disease course or had lower baseline symptom burden – providing insight into the potential importance of addressing pathogenic immunoglobulin G (IgG) early in disease progression where use of advanced therapies may be less common.1,2 Additional research to be shared include outcomes shortly after common infections, which are a known cause of disease exacerbations in gMG, and plans to address evidence gaps in use of IMAAVY during pregnancy.3,4
