Provided are a bispecific antibody and use thereof. The bispecific antibody comprises a B7-H4-targeting antigen-binding domain and a 4-1BB-targeting antigen-binding domain. The bispecific antibody has one or two or three sites for binding to 4-1BB, along with a novel fully human B7-H4 antibody. The bispecific antibody specifically binds to tumor cells by targeting B7-H4, reducing toxicity induced by 4-1BB activation. In addition, the bispecific antibody of the present invention comprises a human Fc fragment, and thus retains the binding of Fc to FcRn and has a longer half-life.

The present invention relates to antigen-binding molecules, pharmaceutical compositions, and methods. The present invention provides antigen-binding molecules that bind to C1s and comprise a heavy chain variable region, a light chain variable region and an Fc region.

Antibodies and antigen-binding fragments thereof with high affinity for CD3 and desirable developability profiles are provided, as well as methods for their manufacture and use.

The present invention relates, in part, to agents that bind PD-L1 and their use as diagnostic and therapeutic agents. The present invention further relates to pharmaceutical compositions comprising the PD-L1 targeting moiety and their use in the treatment of various diseases.

Soluble fusion protein complexes, including domains from IL-15, IL-15 receptor, and αCTLA4 antibody for preventing, reducing the occurrence of, and/or treating cancer or an autoimmune disease or disorder in a subject are provided herein. The methods provided herein include administering to a subject a pharmaceutical composition of a soluble fusion protein complex.

The present disclosure provides antibodies and polypeptides that specifically bind to mesothelin (MSLN), including bispecific antibodies that bind both MSLN and a T cell antigen (e.g., CD3). Also provided are pharmaceutical compositions comprising these antibodies, nucleic acids encoding these antibodies, expression vectors and host cells for making these antibodies, and methods of treating a subject using these antibodies.

Antibodies and compositions against IGF-1R and uses thereof are provided herein.

The present invention relates in part to amino acid sequences that are directed against and/or that can specifically bind to an envelope protein of a virus, as well as to compounds or constructs, and in particular proteins and polypeptides, that comprise or essentially consist of one or more such amino acid sequences.

The present invention relates to novel antibodies and fragments thereof that binds cannabinoid 1 (CB1) receptor. The antibodies and fragments thereof as disclosed herein include humanized antibodies that bind CB1 receptor. The invention also includes uses of the antibodies for treating a disease or disorder responsive to antagonism or agonism of the CB1 receptor.

The present invention relates to methods of selecting, screening, engineering, making and modifying antibodies that have improved bioavailability upon subcutaneous administration to a human. Antibodies and variant antibodies with improved bioavailability upon subcutaneous administration to a human are also described.
