• Known history of chronic liver disease (e.g., alcoholic liver disease, primary biliary cirrhosis, autoimmune hepatitis, Wilson's disease, hemochromatosis)
• Clinically significant cardiovascular disease within the past 6 months (e.g., heart attack, unstable angina, stroke, heart failure NYHA Class III/IV, pulmonary embolism, significant arrhythmias), cardiac pacemaker, or QTcF greater than 480 msec on screening ECG
• Prior cancer progression on abiraterone (stopping abiraterone due to side effects is allowed)
• Known allergy to any study drug
• Any other condition that, in the opinion of the investigator, would prevent safe participation

• Age 18 years or older
• Diagnosis of prostate cancer (adenocarcinoma) confirmed by tissue sample, without neuroendocrine or small cell features
• Currently taking or recently treated with enzalutamide, darolutamide, or apalutamide (within 30 days of screening) and willing to switch to or restart enzalutamide for this study
• Cancer has spread to bone or soft tissue (metastatic disease), confirmed by imaging
• ECOG performance status of 0, 1, or 2 (able to care for self and up and about more than 50% of waking hours)
• Testosterone level less than 50 ng/dL at screening, with ongoing hormone deprivation therapy or prior surgical castration
• If receiving bone-protective therapy (e.g., denosumab or bisphosphonates), must be on a stable dose for at least 4 weeks
• Evidence of cancer progression while on enzalutamide, darolutamide, or apalutamide, shown by rising PSA, worsening disease on imaging, or new bone lesions
• Adequate organ function based on blood tests within 28 days of starting treatment, including adequate blood counts, kidney function, and liver function
• Willing to use acceptable birth control during the study and for 30 days after the last dose
