Mechanism of Action

Targets/IC₅₀/Ki	TrkA TrkB TrkC ROS1 ALK
In vitro	Entrectinib selectively blocks proliferation of ALK-dependent cell lines and potently inhibits ALK‐dependent signaling. This compound also highly inhibits cell growth of the NSCLC cell line NCI‐H2228 bearing the EML4-ALK rearrangement.
In vivo	In mice bearing Karpas-299 and SR-786 xenografts, Entrectinib (p.o.) induces complete tumor regression. In NPM-ALK transgenic mice, this compound induces complete regression of tumor masses observed in the thymus and in lymph nodes. In the NB xenograft model, this compound cotreatment enhanced the efficacy of conventional chemotherapy.
