Patents Assigned to ELIXIRON IMMUNOTHERAPEUTICS (HONG KONG) LIMITED
  • 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: 11396549
    Abstract: The present disclosure provides antibodies, including antibody fusions, which specifically bind to human CSF1 receptor protein (huCSF1R) and are capable of decreasing, inhibiting, and/or fully-blocking immune regulatory effects mediated by huCSF1R, such as regulation of TAMs 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 CSF1 binding to CSF1R.
