These patients will be allocated into their respective cohort after OncoPanel results return
- Willingness to provide leftover metastatic biopsy tissue for correlative studies, if obtained for clinical purposes
- Based on its mechanism of action and data from animal studies, nivolumab can cause fetal harm. For this reason non-sterilized men who are sexually active with a female partner of childbearing potential treated or enrolled on this protocol must agree to use adequate contraception prior to the study, for the duration of study participation, and for 7 months after last dose of nivolumab administration * Adequate contraception includes male condom plus spermicide * Not engaging in sexual activity is an acceptable practice; however, occasional abstinence, the rhythm method, and the withdrawal method are not acceptable methods of contraception * Subjects in this study should refrain from sperm donation
- Ability to understand and the willingness to sign a written informed consent document, or have a legally authorized representative sign on the subject's behalf
- Subjects must not have received prior ADT (luteinizing hormone-releasing hormone [LHRH] analogue +/- antiandrogen), chemotherapy, or immunotherapy for prostate cancer. The following exception is allowed: * Subjects who have initiated ADT prior to study registration and are able to complete biomarker pre-screening, cohort allocation, and start cycle 1 day 1 (C1D1) study chemoimmunotherapy =< 120 days from initiation of ADT are allowed ** The 120-day window commences at the start of either the antiandrogen agent or LHRH analogue, whichever is earlier * Antiandrogens (e.g., bicalutamide or flutamide) may be used in addition to LHRH analogue =< 60 days before initiation of LHRH analogue to cover the testosterone surge associated with certain LHRH agonists but must be discontinued prior to study registration * Second-generation hormonal agents (e.g., abiraterone acetate) are not allowed
- Subjects must not have undergone prostatectomy * Prostate radiation is allowed before or after study enrollment and may be delivered concurrently with study chemoimmunotherapy, per provider discretion, assuming adequate prostate biopsy tissue is collected before prostatic radiation * Metastasis-directed radiation is allowed before or after study enrollment and may be delivered concurrently with study chemoimmunotherapy, per provider discretion
- Subjects who are receiving any other investigational agents
- Any previous treatment with a PD-1 or PD-L1 inhibitor
- Subjects with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events (AEs)
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to docetaxel (including any drugs formulated with polysorbate 80), nivolumab, or LHRH analogue (e.g., leuprolide, goserelin acetate, degarelix)
