Abstract: Provided herein are antibodies that specifically bind to GPRC5D. Also described are related polynucleotides capable of encoding the provided GPRC5D-specific antibodies or antigen-binding fragments, cells expressing the provided antibodies or antigen-binding fragments, as well as associated vectors and detectably labeled antibodies or antigen-binding fragments. In addition, methods of using the provided antibodies are described. For example, the provided antibodies may be used to diagnose, treat, or monitor GPRC5D-expressing cancer progression, regression, or stability; to determine whether or not a patient should be treated for cancer; or to determine whether or not a subject is afflicted with GPRC5D-expressing cancer and thus may be amenable to treatment with a GPRC5D-specific anti-cancer therapeutic, such as the multispecific antibodies against GPRC5D and CD3 described herein.

Abstract: Provided herein are multispecific antibodies that bind to BCMA, GPRC5D and CD3 and multispecific antigen-binding fragments thereof. Also described are related polynucleotides capable of encoding the provided multispecific antibodies or multispecific antigen-binding fragments, cells expressing the provided multispecific antibodies or multispecific antigen-binding fragments, as well as associated vectors and detectably labeled multispecific antibodies or multispecific antigen-binding fragments. In addition, methods of producing and using the provided multispecific antibodies and multispecific antigen-binding fragments are described. Further provided herein are antibodies that bind to BCMA and antigen-binding fragments thereof.

Abstract: Provided herein are isolated CD3×PSMA-bispecific antigen-binding molecules or bispecific antigen-binding fragment thereof wherein a FN3 domain specifically binds human prostate specific membrane antigen (PSMA) and a second antigen-binding site immunospecifically binds CD3. Also described are fusion proteins and related polynucleotides capable of encoding the provided fusion proteins and, cells expressing the provided fusion proteins. In addition, methods of using the provided isolated CD3×PSMA-bispecific antigen-binding molecules or bispecific antigen-binding fragment thereof are described.
