Trial Summary

What is the purpose of this trial?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.

Participant Groups

The trial is testing if adding darolutamide to standard ADT improves progression-free survival compared to ADT alone in men with mHSPC. Progression-free survival means how long patients live without their cancer getting worse.

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
