Key clinical point: Adding abiraterone plus prednisone to androgen deprivation therapy (ADT) following definitive treatment in patients with biochemically recurrent castration-naïve prostate cancer prolongs prostate-specific antigen (PSA)-free survival (PSA less than 0.2 ng/mL).
Major finding: Abiraterone and prednisone plus ADT vs ADT alone significantly improved PSA-free survival (27.0 months vs 19.9 months; hazard ratio, 0.64; 95% confidence interval, 0.47-0.87).
Study details: A phase 2 , randomized, open-label trial of 200 patients with nonmetastatic biochemically recurrent castration-naïve prostate cancer who were randomly assigned to either abiraterone plus prednisone to ADT or ADT alone following definitive treatment.
