Arm | Intervention/treatment |

Experimental: Darolutamide+ADT
Participants will receive darolutamide 600 mg (2 tablets of 300 mg) twice daily with food and ADT of investigator's choice as standard therapy

Drug: Darolutamide (Nubeqa, BAY1841788)
Coated tablet, oral administration Other: Androgen deprivation therapy (ADT) Luteinizing hormone-releasing hormone (LHRH) agonist/antagonists or orchiectomy |
Placebo Comparator: Placebo+ADT
Participants will receive placebo twice daily with food and ADT of investigator's choice as standard therapy

- Radiological progression-free survival (rPFS) [ Time Frame: 36 months ]Time from the date of randomization to the date of first documentation of radiological progressive disease or death due to any cause, whichever occurs first.
- Overall survival (OS) [ Time Frame: Up to 55 months ]Time from the date of randomization to the date of death from any cause.
- Time to castration-resistant prostate cancer (CRPC) [ Time Frame: Up to 55 months ]Time from the date of randomization to the date of first castration resistant event (radiological progression, PSA progression or symptomatic skeletal events, whichever occurs first).
- Time to initiation of subsequent anti-cancer therapy [ Time Frame: Up to 55 months ]Time from the date of randomization to initiation of first subsequent anti-cancer therapy for prostate cancer.
- Time to PSA progression [ Time Frame: Up to 55 months ]Time from the date of randomization to the date of first prostate-specific antigen (PSA) progression. PSA progression is defined as a ≥25% increase above the nadir (lowest Screening or baseline) value, which is confirmed by a second value 3 or more weeks later, and an increase in absolute value of ≥ 2 ng/mL above nadir, at least 12 weeks from baseline.
- PSA undetectable rates (<0.2 ng/mL) [ Time Frame: Up to 55 months ]The percentage of participants with detectable PSA values (≥0.2 ng/mL) at baseline which become undetectable (<0.2 ng/mL) during the study treatment.
- Time to pain progression [ Time Frame: Up to 55 months ]Time from the date of randomization to pain progression, where progression is defined as an increase of 2 or more points from baseline. Pain to be assessed with a patient reported questionaire.
- Number of participants with adverse events as a measure of safety [ Time Frame: Up to 55 months ]
