Up to 240 mg, Q702 has demonstrated the intended pharmacologic activity with acceptable safety profile. In biomarker analysis, immune modulation activity is exerted by Axl/Mer/CSF1R inhibition. Further assessment of pharmacokinetics, pharmacodynamics, safety and antitumor activity will be performed at the expansion phase at the RP2D in patients with selected advanced tumors.

Q702 induced antitumor activity in syngeneic tumor mouse models by: remodeling the TME toward immune stimulation; expanding M1 macrophage and CD8 T cell populations and decreasing M2 macrophage and MDSC populations in the TME; and increasing MHC class I and E-cadherin expression in tumor cells. Thus, Q702 may have great potential to broaden the coverage of populations benefiting from ICB-based immunotherapy.
