Publication number: 20260199477Abstract: Polyacrylamide-based copolymers act as stabilizing excipients in formulations of antibody biopharmaceutical agents without interacting directly with the antibody or altering its pharmacokinetic properties. The polyacrylamide-based copolymers confer a substantial stability benefit to high concentration compositions of a variety of antibodies by precluding adsorption of the antibody to the interfaces of the composition, preventing undesirable aggregation events and maintaining the binding activity of the antibody. Such antibody compositions are useful in methods of administering the composition to a subject.Type: ApplicationFiled: October 22, 2025Publication date: July 16, 2026Inventors: Eric A. Appel, Joseph L. Mann, John Klich, Catherine M. Kasse
