Abstract: Antibodies and compositions against Insulin-Like Growth Factor-1 Receptor (IGF-1R) and uses thereof are provided herein and antibodies and pharmaceutical compositions that can be used in methods of treating or reducing the severity of thyroid eye disease (TED) in subjects in need thereof, including reducing proptosis and Clinical Activity Score (CAS) in said subjects, by inhibiting the activity of IGF-1R with such antibodies and compositions.

Abstract: The present application addresses the problem of providing an Fc-binding protein having an improved antibody separation ability. The present application also addresses the problem of providing a high-accuracy antibody separation method using an insoluble carrier having the protein immobilized thereon. The problems can be solved by: an Fc-binding protein in which at least an amino acid substitution at a specific position therein occurs and which has reduced affinity for an antibody; and an antibody separation method including allowing an equilibration buffer solution to pass through a column in which an insoluble carrier having the protein immobilized thereon is filled to equilibrate the column, adding a solution containing an antibody to cause the adsorption of the antibody onto the carrier, and eluting the antibody adsorbed on the carrier using an elution solution.

Abstract: Anti-PD-L1 antibodies are disclosed. Also disclosed are pharmaceutical compositions comprising such antibodies, and uses and methods using the same.

Abstract: The present disclosure discloses a method for expressing and preparing a bivalent bispecific antibody. In the present disclosure, each portion of a bivalent bispecific antibody and an immune hybrid protein thereof is respectively expressed in a suitable prokaryotic or eukaryotic cell system, separated and purified by high-performance affinity chromatography, and then spliced in vitro by trans-splicing reaction mediated by an intein, to prepare the bivalent specific antibody and an immune hybrid protein thereof.

Abstract: The object of the present invention is to provide a humanized or mouse-human chimeric anti-podoplanin antibody or an antibody fragment containing the antigen-binding region thereof, and the object is achieved by providing an isolated humanized or mouse-human chimeric anti-podoplanin antibody which comprises a predetermined amino acid sequence, or an antibody fragment containing the antigen-binding region thereof.

Abstract: The present disclosure provides anti-BTC antibodies, methods of producing said antibodies, pharmaceutical compositions comprising said antibodies, and methods of using said antibodies. The present disclosure also provides multi-specific binding molecules, e.g., bispecific antibodies, comprising a BTC binding moiety and an anti-VEGF binding moiety.

Abstract: Provided in the present invention is a bispecific antibody which comprises an anti-MUC1 VHH antibody fragment and an anti-CD16 VHH antibody fragment. The antibody fragment used in the present invention is a variable region sequence derived from a heavy chain camelid antibody and has a high binding affinity to the antigen. Antibody fragments recognizing MUC1 and CD16 are constructed in the same antibody molecule by the invention, so that the antibody molecule can specifically bind to MUC1 and CD16 molecules to promote the killing effect of NK cells on MUC1-positive expression cells and has an inhibiting effect on the growth of MUC1-positive tumors. Also provided is a conjugate of the bispecific antibodies, a related pharmaceutical composition and use.

Abstract: A TIGIT antibody, an antigen-binding fragment thereof, and a medical use thereof. The present invention relates to a murine antibody, a chimeric antibody, and a humanized antibody comprising a CDR region of the TIGIT antibody, and a pharmaceutical composition comprising the TIGIT antibody and the antigen-binding fragment thereof, and a use thereof as a medicament. In particular, the present invention also relates to a use of a humanized TIGIT antibody for preparing a medicament for the treatment of TIGIT-associated diseases or conditions.

Abstract: The invention is concerned with a method of predicting response to a PD-1 axis inhibitor such as anti-PD-L1 antibody by determining the abundance of dendritic cells (DCs) in a tumor tissue sample. The abundance of DCs characterized by enhanced expressions of XCR1, IRF8, BATF3 and FLT3 predicts clinical response to the PD-L1 blockade 5 treatment.
