Arm/Group Title | Bipolar Androgen Therapy + Nivolumab |
---|---|
Arm/Group Description | All participants must have a rising PSA and/or radiographic progression and prior treatment with at least one novel androgen receptor (AR) targeted therapy (i.e. abiraterone acetate, enzalutamide). Up to one taxane agent for metastatic castration-resistant prostate cancer is permitted. Patients will be treated with testosterone cypionate 400mg IM every 4 weeks for a lead-in period of 12 weeks. After the lead-in period, all patients will be treated with nivolumab 480mg IV every 4 weeks and maintained on testosterone cypionate 400mg intramuscular (IM) every 4 weeks. Treatment [with a minimum drug exposure of 12 weeks] will be continued until PSA progression (PCGW3 criteria) or clinical/radiographic progression (whichever comes first), or until unmanageable toxicity requiring drug cessation. |

Measure Description: Prostate-specific antigen, or PSA, is a protein produced by normal, as well as malignant, cells of the prostate gland. The PSA test measures the level of PSA in the blood. For this test, a blood sample is sent to a laboratory for analysis. The results are usually reported as nanograms of PSA per milliliter (ng/mL) of blood.
