This is an observational study in which participants receive a treatment which is already available for doctors to prescribe for non-metastatic castration-resistant prostate cancer (nmCRPC) or metastatic hormone-sensitive prostate cancer (mHSPC). nmCRPC is a prostate cancer that has not yet spread to other parts of the body and does not respond to lowering testosterone in the body. mHSPC is a prostate cancer that has spread to other parts of the body and can be treated by lowering testosterone levels.

This study looks at the safety of the study drug, darolutamide, in Korean patients with nmCRPC or mHSPC. Darolutamide is currently available for doctors to prescribe to men with nmCRPC or mHSPC. It works by attaching to the special molecules called androgen receptors (AR) within prostate cells and blocks hormones called androgens from attaching to AR, which helps delay cancer growth.

To learn more about the safety of Darolutamide, the researchers will study whether the participants have adverse events. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments. The researchers will also learn more about how well darolutamide is working in these participants.

During this study, the researchers will collect information from the medical records of patients who have been prescribed darolutamide by their doctors.

Each participant will be in this study for 1 year. The whole study will last about 6 years. During this time, the participants will visit their doctor every 2 to 4 months as part of their usual care. At these visits, the doctors will do scans to check the patients' cancer and take blood samples. The patients will answer questions about any medications they are taking and whether they have any adverse events.

Inclusion Criteria:

• Male aged ≥19 years

• Patients with high risk nmCPRC

  • Castrate level of serum testosterone (< 1.7 nmol/l [50 ng/dL])
  • PSA doubling time < 10 months

• Patients with mHSPC

  • histologically or cytologically confirmed prostate cancer, and metastases detected on bone scanning, contrast-enhanced computed tomography (CT), or magnetic resonance imaging (MRI).
  • be candidates for androgen-deprivation therapy with/without docetaxel.

• Patients for whom the decision to initiate treatment with Darolutamide as a first time was made as per investigator's routine treatment practice

• Written informed consent from subject or legal representative; assent from subject when appropriate

Exclusion Criteria:

• Patients participating in an investigational program with interventions outside of routine clinical practice
• Participants with contraindication according to the locally approved prescribing information

Patients who have been prescribed Darolutamide for a medically appropriate use will be eligible to be enrolled.

Availability of this study's data will later be determined according to Bayer's commitment to the EFPIA/PhRMA "Principles for responsible clinical trial data sharing". This pertains to scope, timepoint and process of data access. As such, Bayer commits to sharing upon request from qualified researchers patient-level clinical trial data, study-level clinical trial data, and protocols from clinical trials in patients for medicines and indications approved in the US and EU as necessary for conducting legitimate research. This applies to data on new medicines and indications that have been approved by the EU and US regulatory agencies on or after January 01, 2014.
