生物活性:
Sugemalimab is a fully human, full length, anti-programmed death ligand 1 (PD-L1) immunoglobulin G4 (IgG4) monoclonal antibody (mAb). Sugemalimab shows anticancer activities and can be used for non-small cell lung cancer research.

体内研究:
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.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.

体外研究:
Sugemalimab (CS1001) specifically binds to PD-L1, competitively blocks the binding of human PD-L1 with PD-1 and CD80, and effectively induces CD4+?T lymphocyte proliferation and enhances the production of interferon-γ and interleukin-2.Sugemalimab employs IgG4 isotype and lacks antibody-dependent cellular mediated cytotoxicity (ADCC) or complement-dependent cytotoxicity (CDC).
