Phase 1/2RecruitingUniversity of Wisconsin, MadisonNCT04989946Data as of Jun 2026

Treatment: Degarelix · pTVG-AR · Nivolumab · Cemiplimab · Fianlimab · FLT PET/CTThe current protocol will examine the use of a plasmid DNA vaccine encoding AR, alone or with T-cell checkpoint blockade, to induce and/or augment therapeutic T-cells following androgen deprivation in patients with newly diagnosed prostate cancer scheduled to undergo prostatectomy. Patients without evidence of metastatic disease, with tissue remaining from a pre-treatment biopsy, and who are being considered for standard treatment by prostatectomy, will be invited to participate and will be on study for up to 15 months.
