The purpose of the study is to assess if the addition of darolutamide to ADT compared with ADT alone would result in superior clinical efficacy in participants with metastatic hormone-sensitive prostate cancer (mHSPC) by progression-free survival.
The researchers want to learn how long it takes for the cancer to get worse (also known as "progression-free survival") by either increasing symptoms, new metastases, PSA rise or death. All participants will be on treatment and take darolutamide with ADT until their cancer spreads, they have a medical problem, or they leave the study. The results will then be compared with patients' results from another study who received ADT alone (CHAARTED).
This study will also assess safety by gathering adverse event information throughout the duration of the study. An adverse event is any medical problem, related or not to study treatment that a participant has during a study.
The study drug, darolutamide, is already available for doctors to prescribe to patients with prostate cancer that has not yet spread to other parts of the body. It works by blocking a protein called a receptor from attaching to a hormone called androgen that is found in men. This protein can also be found in prostate cancer cells. ADT is a treatment that doctors are currently able to prescribe to patients with mHSPC. ADT is used to lower the amount of the androgen hormone.

Participants will receive darolutamide plus ADT in the ARASEC treatment arm. The control arm for the study will be derived from the participants treated with ADT alone in the CHAARTED trial using a matching approach
Drug: Darolutamide (BAY1841788, Nubeqa)
300 mg per tablet, oral administration with food
LHRH agonist/antagonist or orchiectomy
- Progression-free survival (PFS) [ Time Frame: Approximately 12 months after end of enrollment ]Time interval from enrollment to PSA progression, clinical progression or death, whichever occurs first. PSA progression is defined as when the PSA demonstrates an increase that is more than 50% of nadir, taking as reference the lowest recorded PSA level since starting androgen deprivation therapy (ADT). Clinical progression is defined as increasing symptomatic bone metastases, radiographic progression per Response Evaluation Criteria In Solid Tumors (RECIST) criteria (v. 1.1) for soft tissue metastases and PCWG3 criteria for bone metastases, or clinical deterioration due to cancer per investigator's opinion.
- Overall survival (OS) [ Time Frame: Approximately 24 months after end of enrollment ]Time from the date of enrollment until death resulting from any cause or the date last known alive
- Radiographic Progression-free survival (rPFS) [ Time Frame: Approximately 24 months after end of enrollment ]Time from enrollment to investigator-assessed radiographic progression per Response Evaluation Criteria In Solid Tumors (RECIST) criteria (v. 1.1) for soft tissue metastases and PCWG3 criteria for bone metastases or death, whichever occurs first
- Time to castration-resistant prostate cancer (CRPC) [ Time Frame: Approximately 12 months after end of enrollment ]Time from enrollment until documented clinical or PSA progression with a testosterone level of less than 50 ng per deciliter or documented medical castration or surgical castration
- Complete PSA response rate [ Time Frame: At 6 months after first administration ]PSA level of less than 0.2 ng per milliliter on two consecutive measurements at least 4 weeks apart
- Number of participants with adverse events [ Time Frame: From the signing of the informed consent form (ICF) until 30 (+7) days after last administration, approximately 12 months ]Adverse Events will be assessed by National Cancer Institute-Common Terminology Criteria (NCI CTCAE) v. 5.0
