Brief Summary: This trial will evaluate the use of one versus two DNA vaccines delivered concurrently with PD-1 blockade using pembrolizumab followed by treatment with pembrolizumab alone and delivered over a prolonged period of time for a maximum of 2 years 32 cycles or until radiographic progression on the treatment of castrate-resistant metastatic prostate cancer The hypothesis to be tested is that delivering two vaccines with PD-1 blockade will elicit a greater frequency and magnitude of tumor-directed CD8 T cells and thereby increase the percentage of patients experiencing objective anti-tumor effect as measured by PSA declines andor objective radiographic responses Participants must be 18 years of age or older and can expect to be on treatment for 2 years 32 cycles and on study for up to 7 years including 5 years of follow up via phone
