  • Patent number: 11945864
    Abstract: A monoclonal antibody or an antigen-binding fragment thereof according to an embodiment of the present invention can bind to lymphocyte-activation gene 3 (LAG-3) including a heavy chain variable region and a light chain variable region and inhibit the activity thereof. Thus it is expected to be useful for the development of immunotherapeutic agents for various disorders that are associated with LAG-3.

  • Publication number: 20220348663
    Abstract: Provided are an anti-B7-H3 antibody binding specifically to B7-H3 and a use thereof and, more particularly, are an anti-B7-H3 antibody or an antigen binding fragment thereof, a nucleic acid encoding the same, a vector carrying the nucleic acid, a cell transformed with the vector, a method for preparing the same, an antibody-drug conjugate or a multi-specific antibody comprising the same, and a pharmaceutical composition for preventing or treating cancer, autoimmune disease, or inflammatory disease, or a diagnostic composition, each composition comprising the same. The anti-B7-H3 antibody or antigen binding fragment thereof can bind to human and non-human B7-H3 at high affinity and can be endocytosized after binding thereto. Thus, the anti-B7-H3 antibody or antigen binding fragment thereof, or the antibody-drug conjugate or the multi-specific antibody comprising the same can be advantageously used for preventing, treating, or diagnosing cancer or tumor, autoimmune disease, or inflammatory disease.

  • Patent number: 11306141
    Abstract: The present invention relates to an antibody against delta-like 1 homolog (Drosophila) (DLK1) or an antigen-binding fragment thereof, a nucleic acid encoding the same, a vector comprising the nucleic acid, a cell transformed with the vector, a method for producing the antibody or an antigen-binding fragment thereof, an antibody drug conjugate (ADC) comprising the same, a pharmaceutical composition for treating cancer, a composition for diagnosing cancer, and a chimeric antigen receptor (CAR) and a T-cell engager comprising the same.

  • Publication number: 20220047717
    Abstract: The present disclosure relates to antibody-drug conjugates (ADCs) wherein one or more active agents are conjugated to an anti-B7-H3 antibody through a linker. The linker may comprise a unit that covalently links active agents to the antibody. The disclosure further relates to monoclonal antibodies and antigen binding fragments, variants, multimeric versions, or bispecifics thereof that specifically bind B7-H3, as well as methods of making and using these anti-B7-H3 antibodies and antigen-binding fragments thereof in a variety of therapeutic, diagnostic and prophylactic indications.
