Active ingredient

Nipocalimab

Nipocalimab is a human IgG1 monoclonal antibody specifically targeting the IgG Fc binding site of FcRn with high specificity and high affinity at both neutral (extracellular) and acidic pH (intracellular) resulting in the reduction of circulating IgG, including IgG autoantibodies, without affecting other immunoglobulins (IgA, IgE or IgM).
