Batoclimab is a subcutaneous monoclonal antibody developed by Immunovant that blocks the neonatal Fc receptor (FcRn) — a protein in blood vessel walls that recycles immunoglobulin G (IgG) antibodies back into circulation. In autoimmune diseases driven by pathogenic IgG antibodies, blocking FcRn prevents this recycling, accelerating the breakdown of harmful antibodies and reducing disease activity. Batoclimab is in Phase 3 trials for generalized myasthenia gravis; a known class effect of FcRn inhibitors — including the approved competitor VYVGART (efgartigimod) — is LDL cholesterol elevation, which is monitored as a safety endpoint across all batoclimab trials.

    Generalized Myasthenia Gravis

    IgG-driven autoimmune disorder where antibodies attack neuromuscular junction receptors, causing fluctuating muscle weakness. Affects ~80,000 patients in the US.

  • FcRntarget
    Neonatal Fc Receptor

    A salvage receptor that recycles IgG. Inhibiting it forces IgG degradation, lowering pathogenic antibody levels in autoimmune disease.

  • MG-ADLendpoint
    Myasthenia Gravis Activities of Daily Living

    An 8-item, patient-reported scale (0-24) tracking daily-life impact of myasthenia gravis. Lower scores = less disability. A 2-point reduction is considered clinically meaningful.
