Mechanism of Action

Targets/IC₅₀/Ki	EGFR HER2
In vitro	Specifically designed to potently inhibit oncogenic variants containing activating EGFRex20ins mutations with selectivity over wild-type EGFR, Mobocertinib (TAK-788) is a novel irreversible EGFR TKI. It inhibits viability of various EGFRex20ins-driven cell lines more potently than approved EGFR TKIs.
In vivo	Mobocertinib (TAK788) suppresses growth of EGFRex20ins mutant tumors through EGFR inhibition. Combination treatment with this compound and cetuximab improves efficacy in a head and neck squamous cell carcinoma model (CTG-2130) with EGFRex20ins D770_N771insGL.
