Brigatinib (Alunbrig)

General information

Class/mechanism: Tyrosine kinase inhibitor (TKI); inhibits multiple kinases including anaplastic lymphoma kinase (ALK), ROS1, insulin-like growth factor-1 receptor (IGF-1R), FLT-3, and EGFR deletion and point mutations. Brigatinib inhibited growth of cells with EML4-ALK and NPM-ALK fusion proteins. Brigatinib prevents autophosphorylation of ALK and, subsequently, downstream signaling through STAT3, AKT, ERK1/2, and S6. Brigatinib inhibited cells expressing EML4-ALK, as well as mutant forms of EML4-ALK, such as as G1202R and L1196M. Brigatinib was able to inhibit some mutant forms which are associated with resistance to ALK inhibitors including crizotinib, as well as EGFR-Del (E746-A750), ROS1-L2026M, FLT3-F691L, and FLT3-D835Y.
