             cell carcinoma).

          -  Must have tissue available from the pre-treatment diagnostic biopsy (tissue blocks if
             possible; if not possible, 10 unstained slides from each positive core sample for a
             total of 30 slides).

          -  Must have three core biopsies involved with cancer (a minimum of 6 core biopsies must
             be obtained). Prostate biopsy must be within three months from screening.

          -  Participants must have the following features:

               -  Intermediate-risk disease defined as Gleason 4+3=7 disease OR

               -  High-risk disease defined as Gleason 8-10 OR PSA > 20 ng/dL OR T3 disease (by
                  prostate MRI)

          -  No evidence of metastatic or nodal disease as determined by radionuclide bone scans
             CT/MRI.

          -  Participants must be candidates for RP and considered surgically resectable by
             urologic evaluation.

          -  ECOG performance status 0 to 1 (Appendix A).

          -  Participants must have normal organ and marrow function as defined below:

               -  WBC ≥ 3,000/mcL

               -  ANC ≥ 1,500/mcL

               -  Platelets ≥ 100,000/mcL

               -  Serum potassium ≥ 3.5 mmol/L

               -  AST, ALT, and total bilirubin ≤ 1.5 x Institutional ULN

               -  Calculated creatinine clearance ≥ 60 mL/min

               -  PTT ≤ 60, INR ≤ 1.5 x Institutional ULN unless on warfarin therapy (investigator
                  would need to determine if safe for participant to stop warfarin prior to biopsy
                  and warfarin therapy)

               -  Controlled blood pressure defined as a systolic blood pressure ≤ 140 mmHg and
                  diastolic blood pressure ≤ 90 mmHg on no more than three anti-hypertensive
                  agents. Drug formulations containing two or more anti-hypertensive agents will be
                  counted based on the number of active agents in each formulation.

        Exclusion Criteria:

          -  Prior hormone therapy for prostate cancer including orchiectomy, antiandrogens
             (including first-generation antiandrogens, enzalutamide, ARN-509 and others), CYP17
             inhibitors (including abiraterone, TAK-700, galeterone, ketoconazole, and others),
             estrogens, LHRH agonist/antagonists. Prior therapy with 5α-reductace inhibitors is
             allowed. LHRH therapy allowed if begun within 4 weeks of day 1.

          -  Prior chemotherapy, radiation therapy, or immunotherapy for prostate cancer.

          -  Prior systemic treatment with an azole drug within four weeks of screening visit.

          -  Hypogonadism or severe androgen deficiency as defined by screening serum testosterone
             < 200 ng/dL.

          -  Acute coronary syndrome within 6 months of screening visit;

               -  Hypotension defined as a systolic blood pressure < 86 mmHg;

               -  Bradycardia defined as a heart rate of < 50 beats per minute, unless
                  pharmaceutically induced and thus reversible (i.e. beta blockers);

               -  Uncontrolled angina (requiring escalating doses of nitrates) within 3 months of
                  screening visit;

               -  Congestive heart failure NYHA Class III or IV or subjects with a history of
                  congestive heart failure NYHA Class III or IV, unless screening ECHO results in
                  left ventricular ejection fraction that ≥ 45%;

               -  History of clinically significant ventricular arrhythmias (e.g. ventricular
                  tachycardia, ventricular fibrillation, torsades de pointes);

               -  Prolonged corrected QT interval by the Fridericia correction formula (QTcF) on
                  screening EKG > 470 msec;

                  permanent pacemaker in place;

          -  Individuals with a history of a different malignancy are ineligible except for the
             following circumstances: 1) individuals with a history of other malignancies are
             eligible if they have been disease-free for at least 5 years and are deemed by the
             investigator to be at low risk for recurrence of that malignancy, or 2) individuals
             with the following cancers are eligible if diagnosed and treated within the past 5
             years: non-muscle invasive bladder cancer, basal cell or squamous cell carcinoma of
             the skin.
