Patent number: 11725060Abstract: The present disclosure relates to protein molecules that specifically bind to 5T4 and/or 4-1BB. The molecules may have at least one humanized 5T4-binding or 4-1BB-binding domain. Such molecules are useful for the treatment of cancer. The protein molecule binding to 5T4 or 4-1BB may have a second binding domain that binds to another target. The molecules may bind both 5T4-expressing cells and a cell-surface molecule expressed by an effector cell to enhance effector cell activation, proliferation, survival and/or effector-cell mediated cytotoxicity. The disclosure also provides pharmaceutical compositions comprising the 5T4-binding or 4-1BB-binding polypeptide or protein molecules, nucleic acid molecules encoding these polypeptides and methods of making and using these molecules.Type: GrantFiled: July 20, 2018Date of Patent: August 15, 2023Assignees: Aptevo Reserch and Development LLC, Alligator Bioscience ABInventors: David Bienvenue, Gabriela Hernandez-Hoyos, Lynda Misher, Danielle Van Citters, Peter Ellmark, Anna Sall, Christina Furebring, Laura von Schantz, Sara Fritzell, Laura Varas
