    Novel BTK Mutations Conferring Resistance to Non-Covalent BTK Inhibitors and Alternative Treatment Strategy (ASH 2022)
    Here,we generated and comprehensively characterized BTK and PLCG2 mutations conferring resistance to ibrutinib and five different non-covalent BTKi namely pirtobrutinib (LOXO-305), vecabrutinib (SNS-062), nemtabrutinib (ARQ-531), fenebrutinib (GDC-0853), and RN-486. We also found that cells harboring these novel BTK mutations showed differential sensitivity to the covalent vs. non-covalent BTKi. We further demonstrate the potential of venetoclax as follow up treatment upon resistance to non-covalent BTKi.
