WebBrigatinib (AP26113) is a novel highly selective and potent inhibitor of ALK and ROS1 with a high degree of selectivity. In vitro, brigatinib not only inhibited ALK with 12-fold higher potency compared to crizotinib, but also inhibited IGF-1R, FLT3 and EGFR mutants, with some activity against the EGFRT790M resistance mutation. WebDec 10, 2024 · Secondary resistance mechanisms against FLT3 inhibitors were classified into on-target and off-target mechanisms, in which leukemia cells become dependent on other signaling pathways. 7.1 On-target resistance. In on-target resistance, leukemia cells retain dependency on FLT3 signals but show resistance to FLT3 inhibitors by acquiring …
