Eligibility Criteria
Inclusion Criteria
- •Clinical diagnosis of metastatic prostate cancer.
- •Serum testosterone within institutional limits of normal.
- •PSA ≥ 2 ng/mL within 90 days prior to initiation of androgen deprivation. therapy (for early induction) or prior to registration (for late induction).
- •DEXA scan within 2 years prior to registration.
- •ECG within 42 days prior to registration and QTc interval ≤ 460 msec.
- •LVEF within 42 days prior to registration and within institutional limits of normal.
- •Adequate hepatic function as evidenced by bilirubin ≤ 2 x institutional upper limit of normal (ULN), SGOT (AST) and SGPT (ALT) ≤ 3 x institutional ULN, or ≤ 5 x institutional ULN if liver metastases are present.
- •Adequate renal function as evidenced by calculated creatinine clearance ≥ 40 mL/min.
- •Adequate hematologic function as evidenced by leukocytes ≥ 3,000/mcL, absolute neutrophil count (ANC) ≥ 1,500/mcL, hemoglobin ≥ 9 g/dL, and platelets ≥ 100,000/mcL.
- •Zubrod performance status of 0 -
Exclusion Criteria
- •Known brain metastases.
- •No more than 36 months of prior neoadjuvant and/or adjuvant hormonal therapy.
- •≥ 6 months since completion of androgen deprivation therapy.
- •Prior or concurrent therapy with ketoconazole, aminoglutethimide or abiraterone acetate, or enzalutamide (MDV3100). Concurrent megestrol for hot flashes is allowed.
- •Prior chemotherapy for treatment of metastatic prostate cancer. Prior chemotherapy in the neoadjuvant or adjuvant setting is allowed.
- •≥ 2 years since completion of chemotherapy in the neoadjuvant or adjuvant setting.
- •Concurrent use of experimental therapy is not allowed.
- •≥ 30 days since prior medical castration for metastatic prostate cancer.
- •If method of castration is a LHRH agonist, the patient must be willing to continue the use of LHRH and add bicalutamide or TAK-700 during protocol treatment.
- •If the patient was on an antiandrogen (e.g. bicalutamide, flutamide), the patient must be willing to switch over to bicalutamide or TAK-700 (according to randomization).
Arms & Interventions
ADT + TAK-700
LHRH agonist - given as approved for androgen deprivation at a dose necessary to maintain castrate levels and equivalent to 22.5 mg of Leuprolide IM every 3 months. TAK-700, 300 mg, PO, twice daily
Intervention: TAK-700
ADT + Bicalutamide
LHRH agonist - given as approved for androgen deprivation at a dose necessary to maintain castrate levels and equivalent to 22.5 mg of Leuprolide IM every 3 months. Bicalutamide, 50 mg, PO, q daily
Intervention: Bicalutamide
Outcomes
Primary Outcomes
Overall Survival
Time Frame: Duration of treatment and follow-up until death or 9 years after study start
Overall survival is defined as the time from random assignment to the date of death from any cause
Secondary Outcomes

- Number of Participants With Gr 3 Through 5 Adverse Events That Are Related to Study Drugs(Duration of treatment and follow-up until death or 9 years after study start)
- Long-term Survival(After 10 years of follow-up)
- Progression Free Survival(Duration of treatment and follow-up until death or 9 years after study start)
