In immunocompetent huCD47/huSIRPα-transgenic mice engrafted with MC38 cells engineered to express human PD-L1 and CD47, NI-2901 displayed significant anti-tumor activity….Also, NI-2901 demonstrated significant antitumor activity in vivo and is therefore expected to show improved clinical efficacy over PD-1/PD-L1 blockade alone.
