Abstract: An antibody to insulin-like growth factor 1 receptor (IGF1R) and related compositions and uses.

Abstract: Provided are an anti-4-1BB/anti-EGFR 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: Provided is an anti-4-1BB antibody or an antigen-binding fragment thereof, and uses thereof.

Abstract: The present disclosure provides an anti-PD-L1/anti-LAG3 bispecific antibody capable to effectively block the interactions between PD-L1 and its receptor PD-1 and between LAG3 and its ligand (e.g., a MHC class II molecule and FGL1). The bispecific antibody may have high binding affinity to both of a PD-L1 protein (e.g., a human PD-L1 protein) and a LAG3 protein (e.g., a human LAG3 protein). Also provided are antibodies and fragments that have specificity to the PD-L1 or LAG3 protein alone, or antibodies and fragments having additional specificity to one or more other antigens.

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

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 discloses an anti-ROR1 antibody specifically recognizing human and mouse ROR1. The monoclonal antibody can be usefully used for cancer targeting treatment including detection of various cancer expressing ROR1 through specific binding, and drug delivery to specific cancer, etc. as well as a cancer therapeutic agent, by inhibiting tumors.

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: The present invention relates to a bi-specific antibody that specifically binds to alpha-synuclein and IGF1R, and an use of the bi-specific 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 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 invention relates to an anti-alpha-synuclein antibody preferentially recognizing alpha-synuclein aggregates and a use of detection, diagnosis, and/or treatment or prevention of various diseases caused by accumulation of alpha-synuclein aggregates, or their related symptom diseases by using the anti-alpha-synuclein antibody.

Abstract: Provided is a method of purifying a mixture of Fc-containing bioactive peptides by using an affinity column including an affinity matrix containing a protein A ligand, wherein the mixture of Fc-containing bioactive peptides includes a first Fc-containing bioactive peptide and a second Fc-containing bioactive peptide, and the second Fc-containing bioactive peptide includes at least one more human VH3 domain, compared to the first Fc-containing bioactive peptide. According to the purification method, bioactive peptides having the same or similar structures can be precisely separated to the high level of purity while simplification of the process is achieved.

Abstract: The present disclosure provides an anti-PD-L1/anti-LAG3 bispecific antibody capable to effectively block the interactions between PD-L1 and its receptor PD-1 and between LAG3 and its ligand (e.g., a MHC class II molecule and FGL1). The bispecific antibody may have high binding affinity to both of a PD-L1 protein (e.g., a human PD-L1 protein) and a LAG3 protein (e.g., a human LAG3 protein). Also provided are antibodies and fragments that have specificity to the PD-L1 or LAG3 protein alone, or antibodies and fragments having additional specificity to one or more other antigens.

Abstract: Provided is an anti-4-1 BB antibody or an antigen-binding fragment thereof, and uses thereof.

Abstract: The present invention relates to a novel compound comprising a galactose trigger moiety and cyclopropabenzindole (CBI), and an antibody-drug conjugate prepared by using same.

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