Serum testosterone \>175 ng/dL.~6. Nonmetastatic (M0) disease and no evidence of prostatic bed recurrence verified by whole body bone scintigraphy and either CT or MRI. Note that a positive PSMA PET does not exclude the participant if the conventional scans are negative.~7. Serum PSA of \>0.3 ng/mL for participants with prior radical prostatectomy (with or without salvage radiotherapy), or serum PSA of 2 ng/mL above nadir for participants with prior external beam radiation or brachytherapy.~8. PSA doubling time ≤12 months.~9. Not planning to start ADT for at least 4 months after Day 1.~10. Eastern Cooperative Oncology Group (ECOG) Score 0 or 1.~11. Baseline laboratory parameters must meet the following criteria:~    * Haemoglobin ≥110 g/L~   * White cell count ≥2.0×10\^9/L~   * Absolute neutrophil count ≥1.5×10\^9/L~   * Lymphocytes ≥0.9×10\^9/L~   * Platelets ≥100×10\^9/L~   * Creatinine ≤1.5×upper limit of normal (ULN) OR calculated creatinine clearance ≥50 mL/min by the Cockcroft Gault formula~   * Total bilirubin ≤1.5×ULN, (total bilirubin \>1.5×ULN is acceptable if total bilirubin is fractionated and direct bilirubin \<35%)~   * Alanine aminotransferase ≤1.5×ULN~   * Aspartate aminotransferase ≤1.5×ULN~   * Troponin T within normal range~   * HbA1c \<7 %~12. Agrees to the following during the trial for at least 65 days after the last dose of VTP-850:~    * Refrain from donating sperm PLUS, either~   * Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long-term and persistent basis) and agree to remain abstinent OR~   * Agrees to use a male condom when having sexual intercourse with a woman of childbearing potential, and should also be advised of the benefit for a female partner to use a highly effective method of contraception as a condom may break or leak.~13. Agrees to comply with all scheduled visits, VTP-850 administration plan, laboratory tests, lifestyle considerations and other trial procedures~Exclusion Criteria:~1. Any other prior malignancy within the past 5 years except for basal cell or squamous epithelial carcinomas of the skin that have been resected with no evidence of metastatic disease for 3 years.~2. Unstable medical condition, drug or alcohol abuse, or medical or psychiatric condition that in the opinion of the investigator would affect the safety of the participant or the evaluation of the data or interfere with adherence to the trial requirements.~3. Significant history of or current cardiovascular, respiratory, renal, gastrointestinal, endocrinological, haematological or neurological disorders constituting a risk when taking the trial intervention or interfering with the interpretation of data; cardiac event or heart failure in the previous 6 months.~4. Current or chronic history of liver disease. This includes but is not limited to: hepatitis virus infections, cirrhosis, drug- or alcohol-related liver disease, non alcoholic steatohepatitis, autoimmune hepatitis, hemochromatosis, Wilson's disease, α-1 antitrypsin deficiency, primary biliary cholangitis, primary sclerosing cholangitis or any other liver disease considered clinically significant by the investigator. (Note that history of hepatitis C infection, Gilbert's syndrome or non alcoholic fatty liver not associated with steatohepatitis are not exclusions. In line with Exclusion Criterion 10, active hepatitis C infection is exclusionary.)~5. Active autoimmune disease that has required systemic treatment in past 2 years with use of disease modifying agents, chronic corticosteroids (\>14 days) or immunosuppressive drugs. Hormone replacement therapy (e.g., thyroxine, insulin or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is allowed.~6. History of severe allergy to eggs or history of severe reaction to any previous vaccination that required medical attention.~7. Medical history that could increase the participant's risk of reaction to a vaccine, including but not limited to capillary leak syndrome, transverse myelitis, multiple sclerosis, Guillain Barré syndrome, significant thrombocytopenia, thrombosis with thrombocytopenia syndrome (also termed vaccine-induced thrombotic thrombocytopenia), heparin-induced thrombocytopenia, or hereditary angioedema, acquired angioedema or idiopathic angioedema.~8. Any immunocompromised state, or history of solid organ or stem cell transplantation.~9. Active infection requiring parenteral antibiotic therapy or causing fever (temperature ≥38.0˚C) within 7 days prior to Day 1, or unexplained fever (temperature ≥38.0˚C) within 7 days prior to Day 1.~10. Known history of infection with hepatitis B virus, or human immunodeficiency virus, or active hepatitis C virus infection (antibody and RNA positive).~11. Received XRT following radical prostatectomy within 6 months prior to Day 1.~12. Received ADT outside of the initial primary therapy~13. Prior chemotherapy or immunotherapy (including vaccines or checkpoint inhibitors) or experimental agent or participation in a clinical trial for prostate cancer with the exception of those taking part as primary treatment option.~14. Received a vaccine with adenovirus vector within 3 months prior to Day 1.~15. Received any live vaccine within 30 days prior to Day 1, or planned vaccination to occur within 3 months after Day 1.~16. Received any non-live/inactivated vaccine within 14 days of Day 1 or planned non-live vaccination to occur within 10 weeks after Day 1.~17. Administration of immunoglobulins and/or any blood products within 28 days prior to Day 1.~18. Condition requiring systemic treatment with corticosteroids or other immunosuppressive medications within 14 days of first dose of VTP-850. Note that adrenal replacement doses are permitted. Inhaled and topical corticosteroids are allowed.~19. Received an investigational product or investigational surgical procedure in the 3 months prior to Day 1 or planned use during the trial period, or participation at any time in clinical trial for prostate cancer with exception of those taking part as primary treatment.~20. Any significant cardiovascular conditions per the investigator within 6 months before study entry including but not limited to: myocardial infarction, stroke, New York Heart Association class III or IV heart failure, thromboembolic events, major cardiovascular or cerebrovascular procedures, history of cardiac valvular disease or other structural heart disease or any other condition that in the investigator's opinion puts the participant at unacceptable risk to enter the study.~21. Participant with QT interval corrected for heart rate (QTc) determined using Fridericia's formula (QTcF; QTcF = QT/\[R-R interval {RR}\^0.33\]) \> 470 msec and any other ECG findings deemed clinically significant at screening.~22. Uncontrolled hypertension that, in the opinion of the Investigator, puts participant at increased risk of a cardiovascular event at the time of screening.~23. Uncontrolled dyslipidemia that, in the opinion of the Investigator, puts participant at increased risk of cardiovascular event at the time of screening.
