Brief Summary:
This research study is comparing two different combinations of androgen deprivation therapy (ADT) used together with radiation as a treatment for rising PSA after radical prostatectomy (prostate cancer).

Condition or disease Intervention/treatment Phase
Prostate Cancer Drug: GnRH Drug: Bicalutamide Radiation: Salvage radiation Drug: Abiraterone Drug: Prednisone Drug: Apalutamide Phase 2

Detailed Description:

This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational intervention to learn whether the intervention works in treating a specific disease. "Investigational" means that an intervention is being studied. In this study, the investigational agents are apalutamide and abiraterone acetate.

Currently, the best standard treatment for men with this type of prostate cancer includes radiation therapy combined with androgen deprivation therapy (ADT). ADT blocks the function of hormones including testosterone which prostate cancer uses to grow and spread. All participants in this study will receive the main standard form of ADT called a luteinizing hormone-releasing hormone agonist (LHRHA). Physicians often also use another drug called bicalutamide to help the LHRHA block hormone function. The investigators are testing whether using two newer anti-hormonal drugs called abiraterone acetate and apalutamide with LHRHA can improve cure rates compared to using bicalutamide plus LHRHA. These two drugs work together to suppress both testosterone and the receptor where testosterone binds thereby providing more potent hormone suppression.

  2. Metastasis Free Survival only visible by PET Imaging (MFS-PET) [ Time Frame: Up to 5 years ]
    Time from randomization to distant metastasis, visible only by PET portion of a PET-CT, or death due to any cause or censored at date last known alive.

  3. Cause Specific Survival [ Time Frame: Up to 5 years ]
    The interval from randomization to the date of last known follow-up alive or date of death from each of the following causes: prostate cancer, cardiovascular disease, other causes.

  4. Overall Survival [ Time Frame: Up to 5 years ]
    Time from randomization to death due to any cause or censored at date last known alive

  5. Time to Testosterone Recovery [ Time Frame: Up to 5 years ]
    Time from randomization to date at which testosterone level returns to a normal level, or censored at the date of last disease evaluation for those whose testosterone has not reached a normal level

  6. Toxicity as measured by CTCAE v.4.0 [ Time Frame: Up to 5 years ]
    Measure Grade 1-5 toxicities at study visits and follow-up using the CTCAE v.4.0 forms and determine attribution

  7. Time to reinitiation of ADT [ Time Frame: Up to 5 years ]
    Time from randomization to date at which ADT is restarted for disease progression. Censoring occurs at date of last disease evaluation for those who are not restarted on ADT.

  8. Patient reported QOL [ Time Frame: Up to 5 years ]
    Patient-reported Quality of Life will be measured by a fatigue questionnaire

  9. Patient reported QOL [ Time Frame: Up to 5 years ]
    Patient-reported Quality of Life will be measured by a questionnaire assessing symptoms related to prostate cancer

  10. Patient reported QOL [ Time Frame: Up to 5 years ]
    Patient-reported Quality of Life will be measured by a memory survey

  11. Cardiovascular events consisting of myocardial infarction [ Time Frame: Up to 5 years ]
    Time from randomization to date at which first cardiovascular event (myocardial infarction, stroke, deep venous thrombosis, or pulmonary embolism) occurs. Censoring occurs at date of last disease evaluation for those who did not have a cardiovascular event.
