Introduction:

Brigatinib, also known as AP-26113, is an orally active, potent and selective Dual ALK/EGFR inhibitor. AP26113 binds to and inhibits ALK kinase and ALK fusion proteins as well as EGFR and mutant forms. This leads to the inhibition of ALK kinase and EGFR kinase, disrupts their signaling pathways and eventually inhibits tumor cell growth in susceptible tumor cells. In addition, AP26113 appears to overcome mutation-based resistance. ALK belongs to the insuli receptor superfamily and plays an important role in nervous system development; ALK dysregulation and gene rearrangements are associated with a series of tumors. EGFR is overexpressed in a variety of cancer cell types.
