Abstract: Provided herein are cross-reactive antibodies (or antigen binding fragments thereof) that bind to human CTLA4, activatable antibodies that bind to human CTLA4, nucleic acid molecules encoding the same, pharmaceutical compositions thereof, and methods of their therapeutic use (e.g., for treatment of cancer).

Abstract: Provided are antibodies that bind to human CD137 or antigen binding fragments thereof, nucleic acid encoding the same, therapeutic compositions thereof, and their use to enhance T-cell function to upregulate cell-mediated immune responses and for the treatment of T cell dysfunctional disorders, such as tumor immunity, and for the treatment of cancer.

Abstract: The present application provides compositions and methods for treating cancers in a subject using an anti-CD137 antibody and an agent that induces expression of CD137 on an immune cell and/or induces expression of CD137L on a cancer cell of the subject. In some embodiments, the agent is a cytokine such as IL-2. In some embodiments, the agent is a histone deacetylase (HDAC) inhibitor. In some embodiments, the agent is a DNA-damaging agent.

Abstract: The disclosure relates to antibodies against human CSF-1R, methods for their production, pharmaceutical compositions containing said antibodies, and uses thereof.

Abstract: The present application provides compositions and methods for treating cancers, including follicular lymphoma, T cell lymphoma and adenoid cystic carcinoma, using an anti-CD137 antibody that specifically binds to an extracellular domain of human CD137. In some embodiment, combination therapies including the anti-CD137 antibody and an immune checkpoint inhibitor, and/or a chemotherapeutic agent are provided. Biomarkers such as total CD137, membrane bound CD137 (mCD137), soluble CD137 (sCD137), CD137 ligand, Ki67, CD8+ effector memory T (Tem) cells, regulatory T (Treg) cells, and natural killer (NK) cell levels for the methods of treatment described herein are also provided.

Abstract: Provided are heterodimeric proteins comprising polypeptides having CH3 domains with engineered residues that form disulfide bonds and/or salt bridges. Also provided are activatable antibodies targeting CD3 and/or HER2. Compositions, methods of manufacture and methods of treatment using the heterodimeric proteins and the activatable antibodies are further provided.

Abstract: The present disclosure provides antibodies that bind to human CD137 or antigen binding fragments thereof, nucleic acid encoding the same, therapeutic compositions thereof, and their use to enhance T-cell function to upregulate cell-mediated immune responses and for the treatment of T cell dysfunctional disorders, such as tumor immunity, and for the treatment of cancer.

Abstract: The present disclosure provides antibodies that bind to the T-cell co-inhibitor ligand programmed death-ligand1 (PD-L1) protein, and methods of use. In various embodiments of the disclosure, the antibodies are fully human antibodies that bind to PD-L1. In certain embodiments, the present disclosure provides multi-specific antigen-binding molecules comprising a first binding specificity that binds to PD-L1 and a second binding specificity that binds to a tumor cell antigen, an infected cell-specific antigen, or a T-cell co-inhibitor. In some embodiments, the antibodies of the disclosure are useful for inhibiting or neutralizing PD-L1 activity, thus providing a means of treating a disease or disorder such as cancer or viral infection.

Abstract: Provided herein are methods relating to the use of CD137 Ligand (CD137L) expression; methods relating to the use of CD137L expression as a biomarker; and methods for predicting, assessing, and/or aiding in assessment of responsiveness of a subject in need thereof to treatment with particular anti-cancer therapies (e.g., an anti-CD137 antibody, a checkpoint blockade immunotherapy).

Abstract: Provided are antibodies that bind to human CD137 or antigen binding fragments thereof, nucleic acid encoding the same, therapeutic compositions thereof, and their use to enhance T-cell function to upregulate cell-mediated immune responses and for the treatment of T cell dysfunctional disorders, such as tumor immunity, and for the treatment of cancer.
