  • Publication number: 20250092139
    Abstract: The present invention provides antibodies that bind to the T-cell co-inhibitor ligand programmed death-ligand 1 (PD-L1) protein, and methods of use. In various embodiments of the invention, the antibodies are fully human antibodies that bind to PD-L1. In certain embodiments, the present invention 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 invention 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.

  • Publication number: 20240425580
    Abstract: The present invention provides antibodies that bind to interleukin-33 (IL-33) and methods of using the same. The invention includes antibodies that inhibit or attenuate IL-33-mediated signaling. The antibodies of the invention may function to block the interaction between IL-33 and ST2. Alternatively, certain antibodies of the invention inhibit or attenuate IL-33-mediated signaling without blocking the IL-33/ST2 interaction. According to certain embodiments of the invention, the antibodies are fully human antibodies that bind to human IL-33 with high affinity. The antibodies of the invention are useful for the treatment of diseases and disorders associated with IL-33 signaling and/or IL-33 cellular expression, such as inflammatory diseases, or allergic diseases.

  • Patent number: 12162943
    Abstract: The present invention provides nucleic acid molecules that encode antibodies or antigen-binding fragments thereof, which specifically bind human interleukin-4 receptor (IL-4R). Also provided are expression vectors comprising nucleic acid molecule that encode anti-IL-4R antibodies, host cells comprising the expression vectors, and methods of producing anti-IL-4R antibodies or antigen-binding fragments thereof comprising growing the host cells under conditions permitting production of the antibody or fragment, and recovering the antibody or fragment so produced.

  • Publication number: 20240352124
    Abstract: The present invention provides antibodies that bind to CD3 and methods of using the same. According to certain embodiments, the antibodies of the invention bind human CD3 with high affinity and induce human T cell proliferation. The invention includes antibodies that bind CD3 and induce T cell-mediated killing of tumor cells. According to certain embodiments, the present invention provides bispecific antigen-binding molecules comprising a first antigen-binding domain that specifically binds human CD3, and a second antigen-binding molecule that specifically binds human CD20. In certain embodiments, the bispecific antigen-binding molecules of the present invention are capable of inhibiting the growth of B-cell tumors expressing CD20. The antibodies and bispecific antigen-binding molecules of the invention are useful for the treatment of diseases and disorders in which an upregulated or induced targeted immune response is desired and/or therapeutically beneficial.

  • Publication number: 20240316361
    Abstract: The present invention provides antibodies that bind to the T-cell co-inhibitor programmed death-1 (PD-1) protein, and methods of use. In various embodiments of the invention, the antibodies are fully human antibodies that bind to PD-1. In certain embodiments, the present invention provides multi-specific antigen-binding molecules comprising a first binding specificity that binds to PD-1 and a second binding specificity that binds to an autoimmune tissue antigen, another T-cell co-inhibitor, an Fc receptor, or a T-cell receptor. In some embodiments, the antibodies of the invention are useful for inhibiting or neutralizing PD-1 activity, thus providing a means of treating a disease or disorder such as cancer or a chronic viral infection. In other embodiments, the antibodies are useful for enhancing or stimulating PD-1 activity, thus providing a means of treating, for example, an autoimmune disease or disorder.

  • Patent number: 11820815
    Abstract: The present invention provides methods of treating, ameliorating, or inhibiting tumor growth, cancer, or pathological angiogenesis by administering to a subject in need thereof a human antibody or fragment thereof that specifically binds to human delta-like ligand 4 (hDll4) and blocks hDll4 binding to a Notch receptor. The anti-hDll4 antibody or fragment thereof of the present invention have a high affinity with the KD of 500 pM or less, as measured by surface plasmon resonance.

  • Publication number: 20230094591
    Abstract: A human antibody or an antigen-binding fragment which binds human IL-6 receptor (hIL-6R) with a KD of about 500 pM or less and blocks IL-6 activity with an IC50 of 200 pM or less, is provided. In preferred embodiments, the antibody the antibody or antigen-binding fragment binds hIL-6R with an affinity at least 2-fold higher relative to its binding monkey IL-6R.

  • Patent number: 11578135
    Abstract: The present invention provides multispecific antigen-binding molecules and uses thereof. The multispecific antigen-binding molecules comprise a first antigen-binding domain that specifically binds a target molecule, and a second antigen-binding domain that specifically binds an internalizing effector protein. The multispecific antigen-binding molecules of the present invention can, in some embodiments, be bispecific antibodies that are capable of binding both a target molecule and an internalizing effector protein. In certain embodiments of the invention, the simultaneous binding of the target molecule and the internalizing effector protein by the multispecific antigen-binding molecule of the present invention results in the attenuation of the activity of the target molecule to a greater extent than the binding of the target molecule alone.
