Understand and voluntarily sign the ICF; 8. Male participants are required to use adequate non-pharmacological contraception from the start of ICF signing until 180 days after the last dose and are not allowed to donate sperm.
Exclusion criteria
Exclusion criteria: 1. Evidence of brain metastases, spinal cord compression, or urinary tract obstruction; History of other malignancies within 2.5 years or concomitant other active malignancies. Exclude cured localized tumors, such as basal cell or squamous cell carcinoma of the skin, superficial bladder cancer or carcinoma in situ of the breast, etc.; 3. Those who have undergone any major surgery (including but not limited to transurethral resection of the prostate, radical prostatectomy, etc.) within 4 weeks before the screening visit, or who have undergone major surgery during the planned trial; 4. Previous adrenalectomy, pituitary resection or pituitary lesions; 5. Received radiotherapy within 2 weeks before the first dose; 6. Prostate cancer patients who have undergone or are undergoing endocrine therapy (surgical castration or other endocrine therapy including GnRH receptor agonists, GnRH receptor antagonists, antiandrogens, estrogen, megestrol acetate, etc.), except for prostate cancer patients undergoing prostatectomy, radiotherapy or cryotherapy, if they have received neoadjuvant endocrine therapy/adjuvant endocrine therapy for no more than 6 months, except for those who have terminated the above treatment for more than 6 months before screening; 7. Patients with confirmed or suspected hormone-resistant prostate cancer; 8. Those who have used 5-a reductase inhibitors (finasteride, dutasteride, erristeride, etc.) within 3 months before randomization; 9. Patients who are using or plan to use traditional Chinese medicine, proprietary Chinese medicine, health care products and drugs that may affect serum testosterone concentration during the trial period, if the indications or functional indications of traditional Chinese medicine, Chinese patent medicine, and health care products include the words "treatment of prostate cancer", "affecting androgen levels", "aphrodisiac", etc., the first dose should be discontinued >=4 weeks; 10. Have received an investigational drug, investigational biological product, or investigational medical device, and have discontinued the drug within 1 month before the first dose or within 5 half-lives of the corresponding drug, whichever is longer; 11. HBsAg positive and HBV-DNA higher than the lower measurable limit, HCV antibody positive and HCV-RNA higher than the lower measurable limit; Positive anti-HIV antibody initial screening; 12.
