  • Publication number: 20250388704
    Abstract: Provided herein are novel anti-CD28 x anti-PSMA antibodies and methods of using such antibodies for the treatment of PSMA-associated cancers. Subject anti-CD28 x 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 x anti-PSMA antibodies) for the treatment of prostate cancers.
    Type: Application

  • Patent number: 12378326
    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.
