PROSELICA (NCT01308580) was a post-marketing requirement to demonstrate non-inferiority of C20 vs C25 in terms of overall survival (OS) in mCRPC pts who progressed on D.


Post-D mCRPC pts were randomized 1:1 to receive C25 or C20 (+ prednisone). To show non-inferiority of C20 (preservation of ≥ 50% of the incremental C25 efficacy over mitoxantrone in the TROPIC trial) with 95% confidence interval (CI), hazard ratio (HR) could not exceed 1.214 under a 1-sided 98.89% CI after interim analyses. Secondary endpoints: progression-free survival (PFS), prostate-specific antigen (PSA) and tumor response (TR), safety, HRQL (Functional Assessment of Cancer Therapy-Prostate [FACT-P] questionnaire) and pain response (PR; Present Pain Intensity score on McGill-Melzack scale). Post-hoc analyses assessed association of Grade 3–4 neutropenia on treatment and baseline (BL) neutrophil-lymphocyte ratio (NLR) with OS.


1200 pts were randomized (598 C20; 602 C25). BL pt characteristics were similar for C20 and C25. See Table for efficacy results. Rates of Grade 3–4 treatment-emergent adverse events were 39.7% C20, 54.5% C25. Change in FACT-P total score from BL was not significantly different for C20 and C25. Grade 3–4 neutropenia on treatment and BL NLR 


In post-D mCRPC pts, C20 is non-inferior in terms of OS vs C25, meeting the study endpoint. Efficacy parameters favoured C25. Grade 3–4 neutropenia and low NLR may have prognostic value. Funding: Sanofi Genzyme.
