Patent ID: 10954567

Abstract:
Described herein are mutations that confer resistance to treatment with a BTK inhibitor. Described herein are modified BTK polypeptides that exhibit decreased inhibition (i.e. are resistant) to a covalent and/or irreversible BTK inhibitor. Also described herein modifications of PLCy2 and CARD 11 polypeptides that confer resistance to treatment with a BTK inhibitor. Described herein are diagnostic methods for detecting the modified polypeptides and nucleic acids encoding the modified polypeptides and applications of the methods thereof. Described herein are compositions, combinations, and kits containing the modified polypeptides and methods of using the modified polypeptides. Also described herein are methods of using modified BTK polypeptides as screening agents for the identification and design of second-generation BTK inhibitors.
