Abstract 794: CG

Webgeneration BTK inhibitors such as ibrutinib covalently binds to a cysteine residue (“C481”) of BTK. Their most frequent acquired resistance is the development of a serine mutation in the binding site (“C481S”). Next generation BTK inhibitors such as HMPL-760 aim to overcome this resistance to first-generation inhibitors.
