Abstract: Embodiments of the present invention provide isolated proteins comprising antigen binding domains that bind kallikrein related peptidase 2 (hK2), including monospecific and bispecific antibodies. Additional embodiments of the invention provide polynucleotides encoding the hk2-specific proteins, vectors, host cells, and methods of making and using them.

Abstract: Provided herein, in certain aspects, are antibodies that bind to PSMA, as well as recombinant cells containing the vectors, and compositions comprising the antibodies. Also provided herein, in certain aspects, are multispecific antibodies that bind to PSMA and CD3, as well as recombinant cells containing the vectors, and compositions comprising the antibodies. Methods of making and using the antibodies are also provided.

Abstract: Antibodies and antigen binding regions that bind delta-like protein 3 (DLL3) are described. Multispecific antigen-binding constructs, such as bispecific antibodies, containing the antigen-binding regions that bind to DLL3 are also described. The application also describes methods of treatment or detection using the anti-DLL3 antibodies, antigen-binding fragments or multispecific antigen-binding constructs thereof, and related molecules, compositions and methods.

Abstract: Provided herein are novel anti-CD28×anti-PSMA antibodies and methods of using such antibodies for the treatment of PSMA-associated cancers. Subject anti-CD28×anti-PSMA antibodies are capable of agonistically binding to CD28 costimulatory molecules on T cells and PSMA on tumor cells. Thus, such antibodies selectively enhance anti-tumor activity at tumor sites while minimizing peripheral toxicity. The subject antibodies provided herein are particularly useful in combination with other anti-cancer therapies (e.g., anti-CD3×anti-PSMA antibodies) for the treatment of prostate cancers.
