Mechanism of Action

Targets/IC₅₀/Ki	FGFR RET CSF-1R PDGFR Kit VEGFR2
In vitro	JNJ-42756493 is a potent, oral pan-FGFR tyrosine kinase inhibitor with half-maximal inhibitory concentration values in the low nanomolar range for all members of the FGFR family (FGFR1 to FGFR4), with minimal activity on vascular endothelial growth factor receptor (VEGFR) kinases compared with FGFR kinases (approximately 20-fold potency difference). In vitro, the proliferation of cells treated with this compound is decreased, associated with increased apoptotic death and decreased cell survival.
In vivo	In vivo, growth of NCI-H716 tumors is delayed by 5 days by drug treatment alone, although when drug delivery is stopped the relative tumor volume increased compared to control. This compound shows favorable drug like properties and displays a high distribution to lung, liver and kidney tissue. It is well tolerated at efficacious doses and results in potent dose-dependent antitumor activity accompanied by pharmacodynamic modulation of tumor FGFR and downstream pathway components.
