i) The number of bone metastases is 4 or more.
ii) 1 or more bone metastatic lesion outside the pelvis and vertebral bodies.
<2> Visceral metastasis (other than bone, lymph nodes, and skin) is observed on contrast-enhanced CT.
3) Males aged 18 years or older.
4) ECOG Performance status 0 to 2.
5) No ADT or within 84 days (12 weeks) from ADT start. If ADT has been started before the primary registration, one of the following <1> or <2>.
<1>All of the following i) and ii) when ADT with drugs is performed.

<2> Within 84 days (12 weeks) from the day of the bilateral orchiectomy as ADT.
6) ARAT (abiraterone + prednisolone, enzalutamide, apalutamide) has not been administered.
7) presence or absence of measurable lesions does not matter.
8) No history of administration of docetaxel for prostate cancer.
9) No history of local surgical treatment or radiotherapy for prostate cancer. However, if there is a history of radiation to bone metastases in the pelvic region or testicular tumor, consult with a radiologist/radiation oncologist to ensure that the total radiation dose is less than a limited dose for each organ.

<1> No exacerbation of the primary disease was observed in any of the evaluations.
<2> Neither suspected progression of bone lesions nor suspected progression of PSA.
4) From 168 days (24 weeks) to 196 days (28 weeks) from the primary registration date.
5) The date of secondary registration is 28 days (4 weeks) from the date of second imaging evaluation.

7) Adequate function of major organs.
1) Synchronous or metachronous (within 5 years) malignancies.
2) Infectious disease requiring systemic treatment.
3) Pyrexia of 38 or higher degrees centigrade.
