  • Patent number: 11945892
    Abstract: A polyacrylamide-based copolymer reduces or prevents aggregation of biologic molecules including proteins, peptides, and nucleic acids, and lipid-based vehicles such as liposomes, lipid nanoparticles, polymerosomes, and micelles, in aqueous formulations at hydrophobic interfaces, thereby increasing the thermal stability of the molecules in the formulation. Methods and compositions comprising the copolymer and a protein or the copolymer and insulin can be used for treating conditions including diabetes.

  • Publication number: 20230372488
    Abstract: 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.

  • Patent number: 11425226
    Abstract: The exemplary embodiments relate to improving the user experience associated with a digital platform. A first user device configured to remotely access a digital platform may receive a first signal broadcast by a second user device. Two or more types of communication protocols that are available to use for establishing a direct communication channel between the user devices are identified. One of the communication protocols is selected and a communication channel is established between the user devices in accordance with the selected communication protocol. The first user device then receives authentication information from the second user and establishes a session with the digital platform based on the authentication information received from the second user device.
