Novel Redirected T-Cell Immunotherapies for Advanced Prostate Cancer

Immunotherapy has failed to achieve durable remissions in advanced prostate cancer patients. More potent T-cell- redirecting strategies may be needed to overcome the immunolog-ically exclusive and suppressive tumor microenvironment. Clinical trials are underway, seeking to define the optimal target for T-cell redirection, such as PSMA, PSCA, or STEAP-1, as well as the optimal strategy, with CAR or bispecific antibodies. As results continue to emerge from these trials, understanding differential toxicity and efficacy of these therapies based on their targets and functional modifications will be key to advancing these promising therapies toward clinical practice. This review provides a unique depth and breadth of perspective regarding the diverse immuno-therapy strategies currently under clinical investigation for men with advanced prostate cancer.

Automated summary

Immunotherapy has not achieved long-lasting remissions in advanced prostate cancer patients. More potent T-cell redirecting strategies are needed to overcome the immunologically exclusive and suppressive tumor microenvironment. This review provides an in-depth perspective on the various immunotherapy strategies currently under clinical investigation for men with advanced prostate cancer.
