  • Publication number: 20240036043
    Abstract: The present disclosure relates to a method for identifying cells that express antigen-specific antibodies with a high binding affinity for a monomeric antigen. Using fluorescence activated cell sorting, cells expressing high affinity antigen-specific antibodies are selected from a population of immune cells isolated from a mammal that has been immunized with or otherwise exposed to the antigen. Nucleic acids encoding the high affinity antibodies can then be cloned into other lymphoid and non-lymphoid cells where the antibody can be expressed and from which the antibodies can be secreted.

  • Publication number: 20230416396
    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.

  • Publication number: 20230416376
    Abstract: Provided herein are antibodies and bispecific antigen-binding molecules that bind MET and methods of use thereof. The bispecific antigen-binding molecules comprise a first and a second antigen-binding domain, wherein the first and second antigen-binding domains bind to two different (preferably non-overlapping) epitopes of the extracellular domain of human MET. The bispecific antigen-binding molecules are capable of blocking the interaction between human MET and its ligand HGF. The bispecific antigen-binding molecules can exhibit minimal or no MET agonist activity, e.g., as compared to monovalent antigen-binding molecules that comprise only one of the antigen-binding domains of the bispecific molecule, which tend to exert unwanted MET agonist activity.
