Study Summary

This trial will compare the efficacy of enzalutamide versus abiraterone/prednisone in men with metastatic castration-resistant prostate cancer.

Who is the study for?
Men aged 18+ with castration-resistant metastatic prostate cancer, who have not used certain treatments recently and do not have severe heart conditions, brain metastases, or other specific health issues. Participants must show disease progression despite ongoing androgen deprivation therapy.Check my eligibility
What is being tested?
The trial is testing if enzalutamide alone is as effective as a combination of enzalutamide, abiraterone, and prednisone in treating advanced prostate cancer that no longer responds to hormonal therapy aimed at lowering androgens.See study design
What are the potential side effects?
Possible side effects include fatigue, high blood pressure, liver problems, bone pain relief procedures like radiation or surgery may be needed. There's also a risk of seizures for those with certain medical histories.
