How does this medicine work?[edit | edit source]

  • Acalabrutinib (a kal" a broo' ti nib) is an orally available, small molecule inhibitor of Bruton’s tyrosine kinase (BTK), which is an essential component in the B cell receptor signaling pathway.
  • Inhibition of this pathway prevents B cell activation, differentiation and proliferation.
  • Deficiency of BTK is the cause of X linked (Bruton’s) agammaglobulinemia, and B cell receptor signaling through BTK has been shown to be critical for proliferation and survival of malignant B lymphocytes in mantle cell lymphoma and CLL.
  • Unlike ibrutinib, another BTK inhibitor, acalabrutinib has a high degree of specificity for BTK and has little or no activity against EGFR and other tyrosine kinases.
