Description: Acalabrutinib, also known as ACP-196, is an orally available inhibitor of Bruton’s tyrosine kinase (BTK) with potential antineoplastic activity. Upon administration, ACP-196 inhibits the activity of BTK and prevents the activation of the B-cell antigen receptor (BCR) signaling pathway. This prevents both B-cell activation and BTK-mediated activation of downstream survival pathways. This leads to an inhibition of the growth of malignant B cells that overexpress BTK. BTK, a member of the src-related BTK/Tec family of cytoplasmic tyrosine kinases, is overexpressed in B-cell malignancies; it plays an important role in B lymphocyte development, activation, signaling, proliferation and survival.

Acalabrutinib is a potent and selective BTK (Bruton's tyrosine kinase) inhibitor. BTK is a cytoplasmic, non-receptor tyrosine kinase that transmits signals from a variety of cell-surface molecules, including the B-cell receptor (BCR) and tissue homing receptors. Genetic BTK deletion causes B-cell immunodeficiency in humans and mice, making this kinase an attractive therapeutic target for B-cell disorders. BTK inhibitors targeting B cell receptor signaling and other survival mechanism showed great promise for the treatment of chronic lymphocytic leukemia (CLL)s holds great promise.
As of 2015 it is in late stage clinical trials for relapsed chronic lymphocytic leukemia. Interim results are encouraging : 95% overall response rate. It is also in another 20 clinical trials (alone and in combination) for various cancers.
