Johnson & JohnsonNew data from Phase 3 Vivacity-MG3 study reinforces efficacy of IMAAVY in gMG, supporting its clinical profile.

Johnson & Johnson announced new data across 12 abstracts at the European Academy of Neurology 2026 Congress, offering deeper insight into the use of IMAAVY throughout the generalized myasthenia gravis treatment journey. New analyses from the Phase 3 Vivacity-MG3 study highlight the impact of IMAAVY in adults with anti-AChR+ or anti-MuSK+ antibody-positive gMG, including patients early in their disease course, those with lower symptom burden, and participants who experienced common infections. The company will also present the innovative PETUNIA study design, which demonstrates how pregnancy outcomes data will be collected following treatment with IMAAVY. IMAAVY is an immunoselective neonatal Fc receptor blocker designed to target and reduce pathogenic immunoglobulin G autoantibodies associated with gMG.
