  • Patent number: 10858430
    Abstract: The present invention is directed to bi-specific monovalent diabodies that comprise two polypeptide chains and which possess at least one binding site specific for an epitope of CD3 and one binding site specific for an epitope of gpA33 (i.e., a “gpA33×CD3 bi-specific monovalent diabody”). The present invention also is directed to bi-specific monovalent diabodies that comprise an immunoglobulin Fc Domain (“bi-specific monovalent Fc diabodies”) and are composed of three polypeptide chains and which possess at least one binding site specific for an epitope of gpA33 and one binding site specific for an epitope of CD3 (i.e., a “gpA33×CD3 bi-specific monovalent Fc diabody”). The bi-specific monovalent diabodies and bi-specific monovalent Fc diabodies of the present invention are capable of simultaneous binding to gpA33 and CD3. The invention is directed to pharmaceutical compositions that contain such bi-specific monovalent diabodies or such bi-specific monovalent Fc diabodies.

  • Publication number: 20200377612
    Abstract: The present invention relates to antibodies and their fragments that are immunoreactive to the mammalian, and more particularly, the human B7-H3 receptor and to uses thereof, particularly in the treatment of cancer and inflammation. The invention thus particularly concerns humanized B7-H3-reactive antibodies and their immunoreactive fragments that are capable of mediating, and more preferably enhancing the activation of the immune system against cancer cells that are associated with a variety of human cancers.
