Inclusion Criteria

* Healthy Participants

1) Male over 19 years old

2) Participants do not have congenital or chronic diseases and have no pathological symptoms or findings as a result of medical examination

3) Participants will be determined to be suitable as subjects as a result of clinical pathology tests such as blood pathology tests, blood chemistry tests, and urinalysis performed at the screening visit

4) Patients who voluntarily agreed to participate in this clinical trial and signed consent form

* Prostate cancer patients

1) Male patients over 19 years of age

2) Patients must have adenocarcinoma confirmed by histopathology or cytology.

3) Blood testosterone level meets the castration criterion (<50 ng/dL).

4) Patients with advanced metastatic castration-resistant prostate cancer who have failed the standard of care, and satisfy the following criteria:
-Previous treatment history for mCRPC: Patients who administered at least one of enzalutamide or abiraterone before/after docetaxel treatment.

-Patients who have confirmed disease progression before screening according to the Prostate Cancer Clinical Trials Working Group (PCWG) 3 standard in the state of internal/surgical castration during/after the previous treatment.

i.Soft-tissue disease progression: Soft tissue disease progression as defined by Solid Cancer Response Assessment Criteria Version 1.1 (RECIST v1.1).

ii. Bone disease progression: 2 or more new bone lesions

5) Patients must maintain androgenic deprivation therapy (ADT).

6) Patients must receive bone resorption treatment.

8) ECOG performance status = 2 patients

9) Patients must have an expected survival period of 6 months or longer

-Serum creatinine = 1.8 mg/dL or eGFR (or GFR) = 40 mL/min/1.73 m2
-Aspartate transaminase (AST) and alanine transaminase (ALT) = 2.5 X ULN (however, AST and ALT = 5 X ULN in patients with confirmed liver metastasis)
-Total bilirubin = 1.5 X ULN (except for Gilbert syndrome)
-Prothrombin time (PT) and activated partial thromboplastin time (aPTT) = 1.5 X ULN
