This phase I trial studies the side effects of anti-PD-1 monoclonal antibody REGN2810 (REGN2810) and/or ipilimumab when given together with stereotactic body radiation therapy before surgery in treating participants with prostate cancer that is growing, spreading, or getting worse, and has spread to other places in the body, or formed a small number of new tumors in one or two other parts of the body. Monoclonal antibodies, such as anti-PD-1 monoclonal antibody REGN2810 and ipilimumab, may interfere with the ability of tumor cells to grow and spread. Stereotactic body radiation therapy is a specialized radiation therapy that sends x-rays directly to the tumor using smaller doses over several days and may cause less damage to normal tissue. Giving anti-PD-1 monoclonal antibody REGN2810 and ipilimumab with stereotactic body radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
Full description
PRIMARY OBJECTIVES:
I. To determine the safety and tolerability for an established effective dose of systemic REGN2810 and intraprostatic ipilimumab with stereotactic body radiation therapy (SBRT) in patients with locally advanced prostate cancer with or without oligometastatic disease.
SECONDARY OBJECTIVES:
I. To determine overall pathologic response rate after radical prostatectomy. II. To determine prostate-specific antigen (PSA) progression free survival in men treated with REGN2810 and intraprostatic ipilimumab with SBRT.
III. To determine radiographic progression free survival in men treated with REGN2810 and intraprostatic ipilimumab with SBRT.
IV. Acute and chronic adverse events (AEs).

Exclusion criteria
Is currently participating and receiving study therapy or has participated in a study of an investigational agent within 4 weeks of the first dose of treatment
Prior treatment with an agent that blocks PD-1/PD-L1 pathway or other immune modulating agents within fewer than 4 weeks of 4 half-lives
Has a diagnosis of immunodeficiency or is receiving any systemic steroid therapy or any form of immunosuppressive therapy within 7 days prior to day 1 of trial treatment
Has had a prior monoclonal antibody within 4 weeks prior to study day 1 or who has not recovered (i.e., ≤ grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier
Has had prior treatment with idelalisib
Has had prior or current treatment with Androgen Deprivation Therapy
Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to study day 1 or who has not recovered (i.e., ≤ grade 1 or at baseline) from adverse events due to a previously administered agent
Has a known additional malignancy that is progressing or requires active treatment; exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin, superficial urothelial cancer, or superficial bladder cancer that has undergone potentially curative therapy

Has evidence of significant liver disease
Has an active infection requiring systemic therapy; prior to dosing with REGN2810 the subject must be at least 5 half-lives from their last dose of antibiotic
Has a history of listeriosis or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator
Has psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial
Has a contraindication to administration of amoxicillin, ampicillin, ciprofloxacin, erythromycin, gentamycin, penicillin, trimethoprim/sulfamethoxazole, and vancomycin
