Summary

This trial is a non-comparative pilot study of apalutamide and abiraterone acetate in African American and Caucasian men with mCRPC. The study's primary goal is to prospectively estimate the median PFS of the two groups of men. Secondary objectives include: PSA kinetics, radiographic assessments, safety and tolerability, and incidence of hypertension in the two populations.

Who is the study for?
This trial is for African American and Caucasian men with metastatic castrate-resistant prostate cancer. Participants must be over 18, have a life expectancy of at least 12 months, and be able to take oral medication. They should not have had certain previous treatments or conditions that could interfere with the study drugs or pose risks.
What is being tested?
The trial tests apalutamide, abiraterone acetate, and prednisone in treating prostate cancer. It's an open-label study where both African American and Caucasian men receive the same treatment to compare progression-free survival (PFS) rates, PSA response, radiographic assessments, safety, and tolerability.
What are the potential side effects?
Potential side effects include high blood pressure; liver issues; immune system changes leading to increased infection risk; gastrointestinal disorders affecting drug absorption; hormonal imbalances affecting adrenal or pituitary function; allergic reactions; seizures in predisposed individuals.
