This study looks at the safety and how well a new drug, *CC-94676*, works for men with a specific type of prostate cancer that has spread and doesn’t respond to usual treatments. Prostate cancer is a disease where cells in a man's prostate grow uncontrollably. The study is for men whose cancer keeps growing even with treatments that lower male hormones, which are often used to slow cancer growth. The study is checking if these men can safely take the drug and if it helps them.

• Eligibility: Men with confirmed prostate cancer that keeps growing despite treatment and a good level of daily activity (ECOG score of 0 or 1).
• Exclusions: Those who had certain treatments or other serious health issues, like recent blood clots or another cancer needing treatment, cannot join.
• Considerations: Participants will be monitored closely for safety. The study will evaluate if the new drug helps and is safe to use.
