Abstract: The present disclosure provides a polynucleotide encoding the anti-PD-L1/anti-4-1BB bispecific antibody capable to effectively block the interactions between PD-L1 and its receptor PD-1 and between 4-1BB and its ligand. The bispecific antibody may have high binding affinity to both of a PD-L1 protein and a 4-1BB protein.

Abstract: The present disclosure relates to a bispecific antibody that specifically binds to alpha-synuclein and IGF1R, and an use of the bispecific antibody for the prevention, treatment and/or diagnosis of synucleinopathies associated with alpha-synuclein or alpha-synuclein aggregates, and can allow the alpha-synuclein antibody or an antigen-binding fragment thereof to penetrate the blood brain barrier to exert its action in the brain, and extend the half-life to maintain the efficacy for a long time.

Abstract: Provided are an anti-4-1BB/anti-HER2 bispecific antibody, and a pharmaceutical composition and a method for treating and/or preventing a cancer using the same.

Abstract: The present disclosure provides isolated binding proteins such as humanized antibodies and antigen-binding fragments thereof that target alpha-synuclein, including multispecific isolated binding proteins that target both alpha-synuclein and insulin-like growth factor 1 receptor. Also provided are methods of using the binding proteins to treat alpha-synucleinopathies.

Abstract: The present disclosure provides an anti-PD-L1/anti-4-1BB bispecific antibody capable to effectively block the interactions between PD-L1 and its receptor PD-1 and between 4-1BB and its ligand. The bispecific antibody may have high binding affinity to both of a PD-L1 protein and a 4-1BB protein.

Abstract: The present disclosure provides an anti-B7-H4/anti-4-1BB bispecific antibody capable to effectively block the T-cell inhibitory effect of B7-H4 on the surface of tumor cells, and simultaneously activate 4-1BB on T-cells. The bispecific antibody may have high binding affinity to both of a B7-H4 protein (e.g., a human, monkey and mouse B7-H4 protein) and a 4-1BB protein (e.g., a human, monkey and mouse 4-1BB protein). The present disclosure also provides an anti-B7-H4 antibody specifically binds to B7-H4 protein.

Abstract: The present invention relates to a bi-specific antibody that specifically binds to alpha-synuclein and IGF1R, and use of the bi-specific antibody for treating or diagnosing synucleinopathies associated with alpha-synuclein or alpha-synuclein aggregates. The IGF1R portion of the bi-specific antibody acts as a shuttle to penetrate the blood brain barrier, allowing the alpha-synuclein portion to exert its action in the brain. Further, the half-life of the bi-specific antibody may be extended to maintain efficacy over time.

Abstract: Provided is an anti-B7-H3 antibody specifically recognizing a B7-H3, which can be usefully as a cancer therapeutic agent, as having an inhibitory activity of an immune checkpoint which induces antibody-dependent cell-mediated cytotoxicity and T cell activation inhibited by B7-H3. In particular, the antibody having the inhibitory activity of an immune checkpoint can be used in combination with other immunoantibody therapeutic agents. In addition, it can be usefully used for cancer targeting treatment including detection of various cancers expressing B7-H3 through specific binding to B7-H3, and drug delivery to specific cancer, etc.

Abstract: The present disclosure relates to a bispecific antibody that specifically binds to alpha-synuclein and IGF1R, and an use of the bispecific antibody for the prevention, treatment and / or diagnosis of synucleinopatheis associated with alpha-synuclein or alpha-synuclein aggregates, and can allow the alpha-synuclein antibody or an antigen-binding fragment thereof to penetrate the blood brain barrier to exert its action in the brain, and extend the half-life to maintain the efficacy for a long time.

Abstract: An anti-B-cell maturation antigen (BCMA)/anti-4-1BB bispecific antibody or an antigen-binding fragment thereof, and use thereof, are provided. The bispecific antibody or an antigen-binding fragment thereof may have high binding affinity to both of a BCMA protein and a 4-1BB protein and may be effectively used to prevent or treat a disease related to BCMA, 4-1BB, or both thereof (e.g., cancer).
