Abstract: The present disclosure provides antibodies and antigen-binding fragments thereof that specifically bind to human B7-H4 (and optionally cynomolgus monkey, mouse, and/or rat B7-H4) and compositions comprising such antibodies or antigen-binding fragments thereof. In a specific aspect, the antibodies or antigen-binding fragments thereof that specifically bind to human B7-H4 increase T cell proliferation, increase interferon-gamma production, and/or deplete B7-H4 expressing cells via ADCC activity. The present disclosure also provides methods for treating disorders, such as cancer, by administering an antibody or antigen-binding fragment thereof that specifically binds to human B7-H4.

Abstract: This application relates to use of CD80 (B7-1) extracellular domain (ECD) polypeptides and CD80-ECD fusion molecules and their use in methods of increasing the number of central memory T cells or for treatment for cancer or for use in cancer vaccine compositions.

Abstract: Methods of treating cancer with antibodies that bind colony stimulating factor 1 receptor (CSF1R) in combination with PD-1/PD-L1 inhibitors are provided.

Abstract: The present invention relates to methods of treating pancreatic cancer with particular dosage regimes of antibodies that bind colony stimulating factor 1 receptor (CSF1R) (e.g. cabiralizumab) in combination with antibodies that bind programmed cell death 1 (PD-1) (e.g. nivolumab).

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: The present application relates to antibodies specifically binding to the V-domain immunoglobulin-containing suppressor of T-cell activation (VISTA) at acidic pH and their use in cancer treatment. In some embodiments, the antibodies bind specifically to human VISTA at acidic pH, but do not significantly bind to human VISTA at neutral or physiological pH.

Abstract: Methods of treating cancer with antibodies that bind colony stimulating factor 1 receptor (CSF1R) in combination with PD-1/PD-L1 inhibitors are provided.

Abstract: Methods of treating cancer with antibodies that bind colony stimulating factor 1 receptor (CSF1R) in combination with one or more immune stimulating agents are provided.

Abstract: Methods of identifying and using PSGL-1 antagonists are provided. Such methods include, but are not limited to, methods of treating cancer. PSGL-1 antagonists include, but are not limited to, antibodies that bind PSGL-1 and antibodies that bind VISTA, wherein the antibodies inhibit PSGL-1 binding to VISTA, e.g., at acidic pH (e.g., pH 6.0), as well as PSGL-1 and VISTA extracellular domain polypeptides.
