背景：            Envafolimab is a humanized single-domain antibody recombinant protein targeting PD-L1, and is the world's first and currently the only nano-antibody used in cancer therapy. Its primary indications are unresectable or metastatic microsatellite highly unstable (MSI-H) or mismatch repair gene defective (dMMR) in adults with advanced colorectal cancer, gastric cancer and other advanced solid tumors. By blocking the action of immune checkpoint PD-1 and its ligand PD-L1, the ability of cancer cells to escape immune is inhibited, thus achieving anti-tumor effects.
