Prostate-Specific Membrane Antigen-Directed Therapy for Metastatic Castration-Resistant Prostate Cancer

Prostate-specific membrane antigen (PSMA) is highly expressed on both benign and malignant prostatic tissue. Prostate-specific membrane antigen-directed therapy is conceptually promising, with a potential to additionally serve as a theranostic model in management of advanced prostate cancer. To date, various approaches have been devised and tested, including radiolabeled PSMA antibodies and inhibitor and antibody-drug conjugates. However, development and progress have faced challenges in determining the optimal combination of payload, PSMA-binding moiety, and linker technology. We review the available clinical data to date in PSMA-directed therapies and discuss the challenges faced.
