WebDespite overall improved outcomes with BTK inhibitors in CLL/SLL, patients may eventually develop resistance to covalent BTK inhibition, and outcomes for these patients were historically poor in the relapsed/refractory setting. 75 Resistance can occur through multiple mechanism, although the most common is a BTK mutation substituting the ... WebApr 10, 2024 · BTK inhibitors have revolutionized the treatment of CLL/SLL and certain B-cell neoplasms. However, the most common resistance mechanism is due to mutations to BTK at the C481 binding site. Nemtabrutinib (MK-1026, formerly ARQ-531) is a noncovalent, potent inhibitor of wild-type and ibrutinib-resistant C481S-mutated BTK.
