  • Publication number: 20250215090
    Abstract: A method is disclosed for the treatment of human subjects diagnosed with immune thrombocytopenia (ITP). The method comprises administering to a human subject a human neonatal Fc receptor (hFcRn) antagonist, optionally in combination with standard-of-care ITP treatment. In certain embodiments, the hFcRn antagonist is efgartigimod (ARGX-113). Standard-of-care ITP treatment may comprise administration of corticosteroids, immunosuppressants, and/or thrombopoietin receptor (TPO-R) agonists.

  • Publication number: 20240325528
    Abstract: Provided herein are unit dosage forms of a biologic that are determined based on a modeling approach, which matches a pharmacodynamic (PD) value of the SC dose with that of a known reference IV dose, while a pharmacokinetic (PK) value of the SC dose is less than that of the IV dose.

  • Patent number: 11505585
    Abstract: Provided are novel FcRn antagonist compositions comprising a variant Fc region that binds specifically to FcRn with increased affinity and reduced pH dependence relative to the native Fc region. Also provided are FcRn antagonists with enhanced CD16 binding affinity. Also provided are methods of treating antibody-mediated disorders (e.g. autoimmune diseases) using the these FcRn antagonist compositions, nucleic acids encoding the FcRn antagonist compositions, recombinant expression vectors and host cells for making the FcRn antagonist compositions, and pharmaceutical compositions comprising the FcRn antagonist compositions.

  • Patent number: 9926364
    Abstract: Provided are chimeric, camelid-human (e.g., llama-human) polypeptides comprising a first antigenic polypeptide portion and a second antigenic polypeptide portion wherein the first antigenic portion is a derived from a first portion of a camelid (e.g., llama) and the second antigenic portion is a human polypeptide homolog of a second portion of the camedid antigen. The chimeric polypeptides are useful inter alia for epitope mapping and generation of antibodies that bind to a desired region of human antigen.
