Abiraterone Acetate in Asymptomatic or Mildly Symptomatic Patients With Metastatic Castration-Resistant Prostate Cancer
RandomizedParallel-groupQuadruple-blindTreatment
Summary
This is a phase 3 study to compare the clinical benefit of abiraterone acetate plus prednisone with placebo plus prednisone in asymptomatic or mildly symptomatic patients with metastatic castration-resistant prostate cancer (CRPC).

Outcome
Met primary endpoint
paper improvement in rPFS was statistically significant with abiraterone treatment versus prednisone (median: 16.5 vs 8.2 mo; HR: 0.52 [95% CI, 0.45-0.61]; p<0.0001). PMID 24647231 ↗
paper treatment with abiraterone acetate prolonged overall survival compared with prednisone alone by a margin that was both clinically and statistically significant. PMID 25601341 ↗
