Abstract: The present application relates to antibodies specifically binding to the V-domain immunoglobulin-containing suppressor of T-cell activation (VISTA) at acidic pH and their use in cancer treatment. In some embodiments, the antibodies bind specifically to human VISTA at acidic pH, but do not significantly bind to human VISTA at neutral or physiological pH.

Abstract: 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.

Abstract: A prodrugged antibody has a blocking moiety attached to a Cys on its heavy or light chain via a linker having a cleavable moiety. The blocking moiety inhibits binding of the antibody to its antigen. Cleavage of the cleavable moiety releases the blocking moiety and restores ability of the antibody to bind to its antigen.

Abstract: Methods of identifying and using PSGL-1 antagonists are provided. Such methods include, but are not limited to, methods of treating cancer. PSGL-1 antagonists include, but are not limited to, antibodies that bind PSGL-1 and antibodies that bind VISTA, wherein the antibodies inhibit PSGL-1 binding to VISTA, e.g., at acidic pH (e.g., pH 6.0), as well as PSGL-1 and VISTA extracellular domain polypeptides.
