This clinical trial is focused on studying a treatment for prostate cancer, specifically for cases that are considered very high-risk and localized, meaning the cancer has not spread to other parts of the body. The treatment being tested is a medication called darolutamide, which is taken as a film-coated tablet. The study will compare the effects of adding darolutamide to standard treatments, which include hormone therapy and radiation therapy, against a placebo. The goal is to see if darolutamide can improve outcomes for patients with this type of prostate cancer.
Participants in the study will receive either darolutamide or a placebo, in addition to their regular treatment. The study is designed to be double-blind, meaning neither the participants nor the researchers will know who is receiving the actual medication and who is receiving the placebo. This helps ensure that the results are not biased. The main focus of the study is to determine if the treatment can help patients live longer without the cancer spreading, which is referred to as metastasis-free survival.
The study will also look at other important outcomes, such as overall survival, which is the length of time patients live after starting the study, and prostate cancer-specific survival, which is the time patients live without dying from prostate cancer. Additionally, the study will monitor the progression of prostate-specific antigen (PSA) levels, which are used to track prostate cancer, and the time it takes for the cancer to become resistant to hormone therapy. The study will also assess the quality of life of participants and any side effects they may experience during the trial.
