Summary
This trial is testing a new drug to treat prostate cancer that has not spread. They will be testing how well it works and if it is safe.
Who is the study for?
Men with nonmetastatic, castration-resistant prostate cancer can join this trial. They must be on hormone therapy or have had surgery to lower testosterone levels, have a rising PSA level with a doubling time of 10 months or less, and no signs of the cancer spreading. Participants should be relatively healthy overall, with an expected lifespan of at least one year.
What is being tested?
The study is testing Enzalutamide's effectiveness and safety against a placebo in men whose prostate cancer hasn't spread but continues to grow despite low testosterone levels. The goal is to see if Enzalutamide can help control the disease better than no treatment (placebo).
What are the potential side effects?
Enzalutamide may cause fatigue, back pain, constipation, joint pain, and hot flashes. It might also affect mental function leading to difficulty concentrating or memory problems. Rarely it could increase seizure risk.
