Abstract: This disclosure provides isolated antibodies that bind specifically to CD27 with high affinity. The disclosure provides methods for treating a subject afflicted with a cancer comprising administering to the subject a therapeutically effective amount of an anti-CD27 antibody as monotherapy or in combination with a checkpoint inhibitor, such as an anti-PD-1, anti-PD-L1, or anti-CTLA-4 antibody.

Abstract: Provided herein are antibodies, or antigen binding portions thereof, that bind to glucocorticoid-inducible TNF receptor (GITR). Also provided are uses of these proteins in therapeutic applications, such as in the treatment of cancer. Further provided are cells that produce the antibodies, polynucleotides encoding the heavy and/or light chain variable region of the antibodies, and vectors comprising the polynucleotides encoding the heavy and/or light chain variable region of the antibodies.

Abstract: The present application relates to antibodies specifically binding to immunoglobulin-like transcript 4 (ILT4), which is also known as LILRB2, LIR2, MIR10, and CD85d, and corresponding nucleic acids, host cells, compositions, and uses. In some embodiments, the antibodies bind specifically to human ILT4, but do not significantly bind to ILT2, ILT3, or ILT5, or to other members of the LILRA or LILRB families.

Abstract: This disclosure provides isolated antibodies, for example, monoclonal antibodies, that specifically bind to the C-C Motif Chemokine Receptor 8 (CCR8) expressed on the surface of a cell and mediate depletion of the CCR8-expressing cell by anti-body-dependent cellular cytotoxicity (ADCC). The disclosure provides methods for treating a subject afflicted with a cancer comprising administering to the subject a therapeutically effective amount of an anti-CCR8 antibody as monotherapy or in combination with an anti-cancer agent such as an immune checkpoint inhibitor, for example, an anti-PD-1 or anti-PD-L1 antibody.

Abstract: Provided herein are antibodies, or antigen-binding portions thereof, that bind to T-cell immunoglobulin and mucin-domain containing-3 (TIM3) protein. Also provided are uses of these antibodies, or antigen-binding portions thereof, in therapeutic applications, such as treatment of cancer. Further provided are cells that produce the antibodies, or antigen-binding portions thereof, polynucleotides encoding the heavy and/or light chain regions of the antibodies, or antigen-binding portions thereof, and vectors comprising the polynucleotides encoding the heavy and/or light chain regions of the antibodies, or antigen-binding portions thereof.

Abstract: The present disclosure provides isolated monoclonal antibodies that specifically bind to LAG-3 with high affinity, particularly human monoclonal antibodies. Preferably, the antibodies bind human LAG-3. In certain embodiments, the antibodies bind both human and monkey LAG-3 but do not bind mouse LAG-3. The invention provides anti-LAG-3 antibodies that can inhibit the binding of LAG-3 to WIC Class II molecules and that can stimulate antigen-specific T cell responses. 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. This disclosure also provides methods for detecting LAG-3, as well as methods for treating stimulating immune responses using an anti-LAG-3 antibody of the invention.

Abstract: 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.
