Drug Name: Ibrutinib [USAN:INN] View Structure
Description: A Btk protein inhibitor.

NCI: An orally bioavailable small-molecule inhibitor of Bruton's tyrosine kinase (BTK) with potential antineoplastic activity. Ibrutinib binds to and inhibits BTK activity, preventing B-cell activation and B-cell-mediated signaling and inhibiting the growth of malignant B cells that overexpress BTK. BTK, a member of the src-related BTK/Tec family of cytoplasmic tyrosine kinases, is required for B cell receptor (BCR) signaling, plays a key role in B-cell maturation, and is overexpressed in a number of B-cell malignancies. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
