The present invention provides isolated monoclonal antibodies, particularly human antibodies, that bind to human Cluster of Differentiation 73 (CD73) with high affinity, and inhibit the activity of CD73, and optionally mediate antibody dependent CD73 internalization. Nucleic acid molecules encoding the antibodies of the invention, expression vectors, host cells and methods for expressing the antibodies of the invention are also provided. Immunoconjugates, bispecific molecules and pharmaceutical compositions comprising the antibodies of the invention are also provided. The invention also provides methods for inhibiting the growth of a tumor cell expressing CD73 using the antibodies of the invention, including methods for treating various cancers.

Antibodies against CD73 and uses thereof

Provided herein are antibodies, or antigen binding portions thereof, that bind to glucocorticoid-inducible TNF receptor (GITR). Also provided are uses of these proteins in therapeutic applications, such as in the treatment of cancer. Further provided are cells that produce the antibodies, polynucleotides encoding the heavy and/or light chain variable region of the antibodies, and vectors comprising the polynucleotides encoding the heavy and/or light chain variable region of the antibodies.

Antibodies against glucocorticoid-induced tumor necrosis factor receptor (GITR)

Provided herein are heavy chain constant regions (referred to as 'modified heavy chain constant regions'), or functionally equivalent fragments thereof, that enhance biological properties of antibodies relative to the same antibodies in unmodified form. An exemplary modified heavy chain constant region includes an IgG2 hinge and three constant domains (i.e., CH1, CH2, and CH3 domains), wherein one or more of the constant region domains are of a non-IgG2 isotype (e.g., IgG1, IgG3 or IgG4). The heavy chain constant region may comprise wildtype human IgG domain sequences, or variants of these sequences. Also provided herein are methods for enhancing certain biological properties of antibodies that comprise a non-IgG2 hinge, such as internalization, agonism and antagonism, wherein the method comprises replacing the non-IgG2 hinge of the antibody with an IgG2 hinge.

Antibodies comprising modified heavy constant regions

Antibodies against CD73

The present disclosure provides isolated monoclonal antibodies, particularly human antibodies, that bind to human Cluster of Differentiation 73 (CD73) with high affinity, and inhibit the activity of CD73, and optionally mediate antibody dependent CD73 internalization. Nucleic acid molecules encoding the antibodies of the disclosure, expression vectors, host cells and methods for expressing the antibodies of the disclosure are also provided. Immunoconjugates, bispecific molecules and pharmaceutical compositions comprising the antibodies of the disclosure are also provided. The disclosure also provides methods for inhibiting the growth of a tumor cell expressing CD73 using the antibodies of the disclosure, including methods for treating various cancers.
