- Age greater than or equal to 18 years old
- Able to understand and sign informed consent
- Must agree to use effective birth control (such as a condom) or abstinence during and for a period of 4 months after the last administration of immunotherapy
Exclusion Criteria

- History of immunodeficiency diseases, hereditary or congenital immunodeficiencies
- Serious intercurrent medical illness
- A clinically significant cardiac disease
- Subjects who have received any prior therapy for prostate cancer
- Subjects who have known brain metastasis, or with a history of seizures, encephalitis, or multiple sclerosis
- Subjects receiving any other investigational agents
- Contraindication to biopsy such as bleeding disorders, ratio of prothrombin time to partial thromboplastin time (PT/PTT) >=1.5 times the upper limit of normal, artificial heart valve
- Contraindication to MRI such as subjects weighing >136 kilograms, allergy to magnetic resonance (MR) contrast agent, subjects with pacemakers, cerebral aneurysm clips, shrapnel injury or implantable electronic devices
