Batoclimab

**Semantic type:** Amino Acid, Peptide, or Protein|Immunologic Factor|Pharmacologic Substance

**Definition:** A human monoclonal antibody directed against the neonatal crystallizable fragment receptor (FcRn), with potential immunomodulating activity. Upon administration, batoclimab targets and binds to FcRn at the immunoglobulin G (IgG) binding site, thereby preventing the interaction between FcRn and the serum protein IgG. By preventing FcRn/IgG binding, batoclimab blocks the FcRn-mediated rescue of IgG, enables IgG degradation and prevents IgG-mediated inflammation. IgG plays a key role in many autoimmune diseases and is an important factor in inflammatory processes.
