This study investigates the effects of adding an investigational medication to the usual chemotherapy regimen for patients with prostate cancer (PCA). Prostate cancer is a disease where cancer cells form in the tissues of the prostate. The study aims to understand the positive or negative effects of this combination treatment on the participants.
Participants will be randomly assigned to different study arms. Some will receive the investigational medication along with their regular chemotherapy, while others may receive a placebo. A placebo is an inactive substance that looks like the investigational medicine but does not contain any medicine. This helps researchers compare the effects of the investigational medicine to those of the standard treatment.
- Who can participate: Adults with a diagnosis of prostate cancer with metastatic or recurrent disease can participate. They must have a life expectancy greater than 12 weeks and adequate organ function.
- Study details: Participants will be assigned to receive either the investigational medication with chemotherapy or a placebo. The placebo is an inactive substance that resembles the investigational medication but has no therapeutic effect. Participants will not be compensated for their involvement in the study.
