Abstract: The present invention provides compositions and methods for treating cancer and inhibiting cytokine release syndrome (CRS). The methods of the present invention comprise administering to a subject in need thereof a therapeutically effective amount of a CD40 antagonist or a CAR-T cell expressing a CD40 antagonist in combination with a therapeutically effective amount of a CD3 multispecific antigen binding molecule.

Abstract: B-cell maturation antigen (BCMA) is expressed on malignant plasma cells. The present invention provides novel bispecific antibodies (bsAbs) that bind to both BCMA and CD3 and activate T cells via the CD3 complex in the presence of BCMA-expressing tumor cells. In certain embodiments, the bispecific antigen-binding molecules of the present invention are capable of inhibiting the growth of tumors expressing BCMA. The bispecific antigen-binding molecules of the invention are useful for the treatment of diseases and disorders in which an upregulated or induced BCMA-targeted immune response is desired and/or therapeutically beneficial. For example, the bispecific antibodies of the invention are useful for the treatment of various cancers, including multiple myeloma.

Abstract: CD38 is expressed on malignant plasma cells. CD28 is a costimulatory molecule required for T-cell activation and survival. Provided herein are novel anti-CD38 antibodies, anti-CD28 antibodies, and bispecific antibodies (bsAbs) that bind to both CD38 and CD28 and act as costimulatory agents to activate T cells via binding CD80 and/or CD86. In certain embodiments, the bispecific antigen-binding molecules of the present invention are capable of inhibiting the growth of tumors expressing CD38. The bispecific antigen-binding molecules of the invention are useful for the treatment of diseases and disorders in which an upregulated or induced CD38-targeted immune response is desired and/or therapeutically beneficial. For example, the bispecific antibodies of the invention are useful for the treatment of various cancers, including multiple myeloma, lymphoma, and leukemia.

Abstract: CD38 is expressed on malignant plasma cells. 4-1BB is a costimulatory molecule required for T-cell activation and survival. Provided herein are novel multispecific antigen binding molecules (MABMs) that bind to both CD38 and 4-1BB, for example, to provide “signal 2” in order to enhance the activation of T cells in the presence of a “signal 1”, provided by a Tumor-associated antigen (TAA)×CD3 bispecific antibody or an allogeneic response provided by an antigen presenting cell. In certain embodiments, the multispecific antigen binding molecules of the present invention are capable of inhibiting the growth of tumors expressing CD38. The multispecific antigen binding molecules of the invention are useful for the treatment of diseases and disorders in which an upregulated or induced CD38-targeted immune response is desired and/or therapeutically beneficial.

Abstract: Provided herein are methods of mediating killing of a tumor cell by administering to the subject a multispecific antigen binding molecule with a first antigen binding region specific for first target antigen and a second antigen binding region specific for a CD28 protein. In some embodiments, the tumor cell does not express the target antigen. In some embodiments, the tumor cell is not predicted to express the target antigen.

Abstract: The present invention provides bispecific antigen-binding molecules comprising a first antigen-binding domain that specifically binds human CD28, and a second antigen-binding molecule that specifically binds human CD-22. In certain embodiments, the bispecific antigen-binding molecules of the present invention are capable of inhibiting the growth of tumors expressing CD-22, such as B-cell lymphomas. The antibodies and bispecific antigen-binding molecules of the invention are useful for the treatment of diseases and disorders in which an up-regulated or induced targeted immune response is desired and/or therapeutically beneficial.
