Inclusion Criteria:

1. Males ≥ 18 years of age
2. Histological diagnosis of adenocarcinoma of the prostate
3. Documented evidence of distant metastasis of disease

5. Patients must have current or historical evidence of disease progression concomitant with surgical (orchiectomy) or medical castration (LHRH analogue); anti-androgen withdrawal (4 weeks for flutamide and 6 weeks for nilutamide or bicalutamide) is necessary only for patients on antiandrogens and a duration of response to antiandrogens > 3months;
6. Testosterone < 50 ng/dL achieved via medical or surgical castration. Patients receiving medical castration therapy must continue such therapy throughout the study.
7. Adequate hematologic, renal and liver function:
8. Negative serology tests for human immunodeficiency virus (HIV-1 and 2), human T-cell lymphotropic virus (HTLV-1), hepatitis B surface antigen (HBsAg) and hepatitis C (HCV)
9. Karnofsky Performance Score (KPS) ≥ 70%
10. Life expectancy > 6 months
11. Written informed consent obtained prior to the initiation of study procedures

Exclusion Criteria:

1. The presence of brain metastases, pleural effusions or ascites
2. Pathologic long-bone fractures, imminent pathologic long-bone fracture (cortical erosion on radiography > 50%), or spinal cord compression
3. A history of stage III or greater cancer, excluding prostate cancer. Basal or squamous cell skin cancers must have been adequately treated and the patient must be disease-free at the time of registration. Patients with a history of stage I or II other cancers must have been adequately treated and been disease-free for 3 years at the time of registration.
4. More than 1 prior chemotherapy, biologic or combination treatment regimen (including vitamin D analogues) for AIPC
5. Any treatment with radiopharmaceuticals, e.g. Strontium-89 and Samarium-153
6. Ketoconazole or antiandrogens (flutamide, nilutamide, bicalutamide) within 2 weeks prior to registration. Patients who demonstrate an anti-androgen withdrawal response, defined as a > 25% drop in PSA within 4 weeks (flutamide) or 6 weeks (nilutamide, bicalutamide) of stopping a non-steroidal anti-androgen, are not eligible until the PSA rises above the nadir observed after anti-androgen withdrawal.
7. Initiation of bisphosphonate therapy within 28 days prior to registration. Patients taking bisphosphonates should not have their dosing regimen altered unless medically warranted.
8. A requirement for systemic steroid or other immunosuppressive therapy for any reason.
9. Treatment with any of the following medications or interventions < 28 days prior to Screening
10. Treatment with any investigational vaccine within 2 years prior to Screening, or treatment with any other investigational product within 28 days prior to Screening
11. Any antibiotic therapy or infection within 1 week prior to Screening, including unexplained fever (temperature ≥ 100.5F or 38.1C)
12. History of autoimmune disease
13. Serious ongoing chronic or acute illness
14. Any medical intervention or other condition which, in the opinion of the Principal Investigator and/or the Bellicum Medical Monitor, could compromise adherence with study requirements
