Patent number: 11578130Abstract: Compositions and methods relating to regulatable chimeric antigen receptors (RCARs), where the intracellular signaling or proliferation of the RCAR can be controlled to optimize the use of an RCAR-expressing cell to provide an immune response, are provided. For example, a RCAR can comprise a dimerization switch that, upon the presence of a dimerization molecule, can couple an intracellular signaling domain to an extracellular recognition element, e.g., an antigen binding domain, an inhibitory counter ligand binding domain, or costimulatory ECD domain. An RCAR can be engineered to include an appropriate antigen binding domain that is specific to a desired antigen target and used in the treatment of a disease.Type: GrantFiled: December 5, 2018Date of Patent: February 14, 2023Assignees: Novartis AG, The Trustees of the University of PennsylvaniaInventors: Jennifer Brogdon, Boris Engels, David Jonathan Glass, Brian Granda, John Hastewell, Andreas Loew, Joan Mannick, Michael C. Milone, Leon Murphy, William Raj Sellers, Huijuan Song, Brian Edward Vash, Jan Weiler, Qilong Wu, Li Zhou

Patent number: 11542488Abstract: Sortase molecules and methods described herein allow for the construction of a CAR or CAR member, e.g., in situ, on a CARX, e.g., CART, cell. For example, sortase mediated transfer of an antigen binding domain, e.g., a scFv, onto a CAR member having a sortase acceptor motif in place of an antigen binding domain can provide for a complete CAR member on a cell wherein the cell does not comprise nucleic acid that encodes the complete CAR member.Type: GrantFiled: July 21, 2015Date of Patent: January 3, 2023Assignees: Novartis AG, The Trustees of the University of PennsylvaniaInventors: Jennifer Brogdon, Carla Guimaraes, John Hastewell, Andreas Loew

Publication number: 20180127485Abstract: The invention provides fibronectin type III (Fn3)-based binding molecules that bind to a specific target antigen. The invention further provides bispecific Fn3-based binding molecules that bind to two or more targets simultaneously. The Fn3-based binding molecules of the invention can also be linked together to form multispecific Fn3-based binding molecules, and/or can be conjugated to a non-Fn3 moiety, such as, Human Serum Albumin (HSA), for improved half life and stability. The invention also provides methods for generating, screening and using Fn3-based binding molecules in a variety of therapeutic and diagnostic applications.Type: ApplicationFiled: November 15, 2017Publication date: May 10, 2018Applicant: NOVARTIS AGInventors: John HASTEWELL, Andreas Loew
