The purpose of this study is to evaluate the effect of an initial hormonal treatment gonadotrophin-releasing hormone (GnRH Agonist) on 2 biomarkers (PCA3 and T2- ERG), in patients with histologically confirmed and advanced stages of prostate cancer. Their characteristics according to risk factors such as PSA, Gleason score will be determined at baseline and 1, 3 and 6 month post-treatment.

Further study details as provided by Ipsen:

Primary Outcome Measures:
  • PCA3 score expressed as a ratio of PCA3 mRNA (messenger ribonucleic acid) over PSA (prostate specific antigen) mRNA. [ Time Frame: 6 months post-treatment ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • PCA3 score expressed as a ratio of PCA3 mRNA over PSA mRNA. [ Time Frame: 1 month and at 3 months post-treatment ] [ Designated as safety issue: No ]
  • TMPRSS2-ERG score (expressed as a ratio of T2-ERG mRNA over PSA mRNA). [ Time Frame: 1, 3 and 6 months post-treatment ] [ Designated as safety issue: No ]
  • Proportion of patients medically castrated (i.e. with serum testosterone levels of <50 ng/dL). [ Time Frame: 1, 3 and 6 months post-treatment ] [ Designated as safety issue: No ]
  • PSA level change. [ Time Frame: From baseline to 1, 3 and 6 months post-treatment ] [ Designated as safety issue: No ]
  • Safety, assessed through the collection of adverse events (AEs). [ Time Frame: For the duration of the study ] [ Designated as safety issue: Yes ]
