The invention relates to anti-Vδ1 antibodies or fragments thereof for use in methods of treating a cancer, an infectious disease or an inflammatory disease in a subject in need thereof.

Provided are anti-PD-L1 antibodies. It also provides the nucleic acid molecules encoding the anti-PD-L1 antibodies, expression vectors and host cells used for the expression of the anti-PD-L1 antibodies. It also provides the methods for producing the anti-PD-L1 antibodies and the use thereof.

Provided are anti-CD137 constructs that bind to CD137, including multispecific anti-CD137 antibodies with binding specificity for CD137 and one or more additional antigens, and methods of using the same. In certain embodiments, the one or more additional antigens comprise human epidermal growth factor receptor 2 (HER2).

The present invention provides anti-CCR8 antibodies and antigen-binding fragments thereof, and methods of making and using said anti-CCR8 antibodies and antigen-binding fragments thereof.

The invention provides anti-cluster of differentiation 3 (CD3) antibodies and methods of using the same.

The present invention provides isolated monoclonal antibodies (e.g., humanized and human monoclonal antibodies) that bind to human Inducible T Cell COStimulator (ICOS) and exhibit therapeutically desirable functional properties, e.g., the ability to stimulate human ICOS activity. Nucleic acid molecules encoding the antibodies of the invention, expression vectors, host cells, and methods for expressing the antibodies of the invention are also provided. Immunoconjugates, bispecific molecules, and pharmaceutical compositions comprising the antibodies of the invention are also provided. The antibodies of the invention can be used, for example, as an agonist to stimulate or enhance an immune response in a subject, e.g., antigen-specific T cell responses against a tumor or viral antigen. The antibodies of the invention can also be used in combination with other antibodies (e.g., PD-1, PD-L1, and/or CTLA-4 antibodies) to treat, for example, cancer. Accordingly, the antibodies can be used in therapeutic applications and methods to detect ICOS protein.

Provided are methods and compositions to target delivery of cells to a tissue lesion, thereby treating the lesion. For example, biotinylated antibodies with affinity to a lesion epitope are administered at the lesion. Reparative cells including avidin and biotin are then administered at the lesion. The reparative cells are targeted to the lesion via avidin-biotin bridges to the antibodies, with additional cells recruited to the lesion via cell-to-cell avidin-biotin bridges. In certain examples, antibody-reparative cell complexes are formed by mixing the biotinylated antibodies with the reparative cells including avidin and biotin. The complexes are then administered at the lesion. In other examples, multivalent antibodies are used to target reparative cells to the lesion, such as by binding an epitope at the lesion and an epitope present on the reparative cell. In other examples, the antibodies are chemically linked to a reparative cell or to a nanosome containing a therapeutic agent.

The present invention provides monovalent antibodies with a long half-life when administered in vivo, methods of making such monovalent antibodies, pharmaceutical compositions comprising such antibodies, and uses of the monovalent antibodies.

The present disclosure provides isolated, engineered, non-naturally occurring CB1 binding proteins, including anti-CB1 antibodies or antigen-binding fragment thereof. The CB1 binding proteins find utility in the treatment and diagnosis of CB1 mediated conditions, diseases and disorders.

The present disclosure provides multispecific binding molecules that specifically bind to BCMA, a component of a human T-cell receptor complex and either CD2 or a tumor associated antigen, conjugates comprising the multispecific binding molecules, and pharmaceutical compositions comprising the multispecific binding molecules and the conjugates The disclosure further provides methods of using the multispecific binding molecules to treat disease and disorders associated with expression of BCMA. The disclosure yet further provides recombinant host cells engineered to express the multispecific binding molecules and methods of producing the multispecific binding molecules by culturing the host cells under conditions in which the multispecific binding molecules are expressed.
