2. The participant has received surgical castration.

3. The participant has ever received LHRH agonists other than commercially available 1-month or 3-month depot of leuprolide acetate.

4. The participant has ever received LHRH antagonists.

5. Patients who have previously received estrogen preparations or corticosteroids for prostate cancer

6. Patients who have previously received chemotherapy for prostate cancer

7. Patients who are receiving or received the marketed product for 3 months (LEUPLIN SR FOR INJECTION KIT 11.25) or the marketed products for 1 month (LEUPLIN FOR INJECTION 3.75 and KIT 3.75) as an adjuvant therapy after prostatectomy and/or radiotherapy

8. Patients who are receiving or received the marketed product for 3 months (LEUPLIN SR FOR INJECTION KIT 11.25) for intermittent androgen deprivation therapy

9. Patients who received the following drugs within 24 weeks (168 days) after starting the study drug: Steroidal antiandrogens, type II 5α-reductase inhibitors
