Abstract: Disclosed herein are compositions and methods for treating cancer in a subject. This involves administering an oncolytic virus containing a heterologous DNA sequence encoding one or more immunomodulatory and/or immunostimulatory polypeptide(s) of interest to the subject under conditions effective to enhance an anti-tumor immune response in the subject, and to treat cancer. It also relates to a method of enhancing the delivery to and distribution within a tumor mass of therapeutic viruses.

Abstract: Provided herein are antibodies, or antigen binding fragments thereof, that selectively bind to NRP-1 and its isoforms and homologs, and compositions comprising the antibodies, or antigen binding fragments thereof. Also provided are methods of using the antibodies, or antigen binding fragments thereof, such as therapeutic and diagnostic methods.

Abstract: Provided herein are antigen-binding proteins (ABPs) that selectively bind to GITR and its isoforms and homologs, and compositions comprising the ABPs. Also provided are methods of using the ABPs, such as therapeutic and diagnostic methods.

Abstract: The disclosure features fusion proteins that are conditionally active variants of a cytokine of interest. In one aspect, the full-length polypeptides of the invention have reduced or minimal cytokine-receptor activating activity even though they contain a functional cytokine polypeptide. Upon activation, e.g., by cleavage of a linker that joins a blocking moiety, e.g. a steric blocking polypeptide, in sequence to the active cytokine, the cytokine can bind its receptor and effect signaling. Typically, the fusion proteins further comprise an in vivo half-life extension element, which may be cleaved from the cytokine in the tumor microenvironment.

Abstract: Provided herein are separation moieties that are suitable for use in conjunction with a variety of therapeutic payloads. The separation moieties serve to generate conditionally active macromolecules whereby the macromolecules have reduced or minimal biological activity until the separation moieties are modified under specific conditions.
