Sugemalimab (CS1001) signifcantly inhibits tumor growth in the subcutaneous MC38-hPD-L1 murine colon carcinoma (murine MC38 cells expressing human PD-L1) in human PD-1 knock-in mouse model^[2].
Sugemalimab not only enhances the cytotoxic T cell/regulatory T cell ratio, but also significantly upregulates M1 macrophage and down-regulated MDSC (myeloid-derived suppressor cells) population in D-1/PD-L1 dual knock-in mice implanted with MC38-hPD-L1 tumor^[2].
