Sitravatinib malate is an orally bioavailable receptor inhibitor of tyrosine kinase (RTK) (IC50s of 1.5 nM, 2 nM, 2 nM, 5 nM, 6 nM, 6 nM, 8 nM, 0.5 nM, 29 nM, 5 nM, and 9 nM for Axl, MER, VEGFR3, VEGFR2, VEGFR1, KIT, FLT3, DDR2, DDR1, TRKA, TRKB, respectively.) , shows potent single-agent antitumor efficacy and enhances the activity of PD-1 blockade through promoting an antitumor immune microenvironment.

In KLN205 and E0771 cell lines,Sitravatinib (0.01 nM-10 μM; 14 days) reduces colony formation in a dose-dependent manner [2]. Sitravatinib (0.001-10 μM; 5 days) inhibits tumor cell viability(IC50s : 1 μM, in KLN205), E0771 and CT1B-A5 cell lines[2].

In C57BL/6 mice bearing CT1B-A5 cells model,Sitravatinib (20 mg/kg; p.o.; once per day for 6 days) significantly inhibits tumor progression and induces tumor regression [2].
