ONO-7475 is a potent and orally active Axl/Mer inhibitor with IC50 values of 0.7 nM and 1.0 nM, respectively. ONO-7475 sensitizes AXL-overexpressing EGFR-mutant NSCLC cells to the EGFR-TKIs, suppresses the emergence and maintenance of tolerant cells. ONO-7475 combines with Osimertinib provides a bright promise for the study of EGFR-mutated non-small cell lung cancer (NSCLC).
Mice fed a diet containing ONO-7475 exhibited significantly longer survival and, interestingly, blocked leukemia cell infiltration in the liver. In summary, ONO-7475 effectively kills acute myeloid leukemia cells in vitro and in vivo by mechanisms that involve disruption of diverse survival and proliferation pathways.

Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
|Body Surface Area (m2)
|Animal A (mg/kg) = Animal B (mg/kg) multiplied by
||Animal B Km
|Animal A Km
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
