  • Publication number: 20230357342
    Abstract: The present disclosure relates a modified interleukin 18 (IL-18) polypeptide, methods of making the same, and methods of using the modified IL-18 polypeptides for treatment of diseases including cancer. The modified IL-18 polypeptide can exhibit an ability to induce interferon gamma (IFN?) production when in contact with a cell, exhibit a diminished ability to be inhibited by IL-18 binding protein (IL-18BP) compared to wild type IL-18 (WT IL-18), and exhibit a ratio of half-maximal inhibitory concentration (IC50) by IL-18BP to half-maximal effective concentration (EC50) to induce IFN? production which is greater than that of WT IL-18.
