    8. Patients who are considered eligible for hormone therapy for prostate cancer.

    9. Patients who have not received hormone therapy (e.g., GnRH agonist, GnRH antagonist, steroidal antiandrogen, non-steroidal androgen) for prostate cancer.

    10. Patients who have not undergone surgical castration. 11. Patients with serum testosterone at screening > 150 ng/dL. 12. Patients meeting either of the following criteria for PSA at screening. Untreated prostate cancer: PSA at screening > 4.0 ng/mL Treated* prostate cancer: PSA at screening > 0.2 ng/mL

    *: Patients who have undergone prostatectomy or either or both of high intensity focused ultrasound therapy or radiotherapy (excluding 125I-brachytherapy) prior to the start of this study.

Exclusion Criteria:
