  • Patent number: 11773167
    Abstract: The present disclosure provides antibodies, including antibody fusions, which specifically bind to human PD-L1 protein (huPD-L1) and are capable of decreasing, inhibiting, and/or fully-blocking immune regulatory effects mediated by PD-L1, such as binding to the immune checkpoint molecule PD-1 in the tumor microenvironment. Additionally, the antibodies include fusions with the cytokine inhibitory factor, IL10, which can replenish and/or activate CD8+ T-cell cytotoxicity in the tumor microenvironment. The present disclosure also provides methods of using the antibodies (and compositions thereof) to treat diseases and conditions responsive to decreasing, inhibiting and/or blocking immune regulatory function or activity mediated by PD1 binding to PD-L1.

  • Patent number: 10752673
    Abstract: Disclosed herein are methods for high-throughput screening of a functional antibody fragment for an immunoconjugate that targets a protein antigen. The method combines a phage-displayed synthetic antibody library and high-throughput cytotoxicity screening of non-covalently assembled immunotoxins or cytotoxic drug to identify highly functional synthetic antibody fragments for delivering toxin payloads.

  • Patent number: 10562976
    Abstract: Disclosed herein is an immunoconjugate comprising an antibody, a functional motif, and a linker connecting the functional motif to the antibody. According to embodiments of the present disclosure, the antibody may recognize tumor-associated antigens (TAAs), and serves as a targeting module for delivering the functional motif connected therewith to the tumor cells thereby inhibiting tumor growth or detecting the distribution of tumor cells. Also disclosed herein are methods of treating cancers and methods of diagnosing cancers by use of the present immunoconjugate.

  • Patent number: 10472411
    Abstract: Disclosed herein is a phage-displayed single-chain variable fragment (scFv) library, that comprised a plurality of phage-displayed scFvs characterized with (1) a specific CS combination; (2) a specific distribution of aromatic residues in each CDR; and (3) a specific sequence in each CDR. The present scFv library could be used to efficiently produce different antibodies with binding affinity to different antigens. Accordingly, the present disclosure provides a potential means to generate different antigen-specific antibodies promptly in accordance with the need in experimental researches and/or clinical applications.
