Experimental: Triptorelin (Decapeptyl®) 22.5 mg |

One intramuscular injection of triptorelin (Decapeptyl®) 22.5mg performed once all baseline procedures and assessments have been completed. |
- PCA3 Score Expressed as a Ratio of PCA3 mRNA (Messenger Ribonucleic Acid) Over PSA (Prostate Specific Antigen) mRNA [ Time Frame: At month 6 post-treatment ]
PCA-3 score = (mRNA PCA3/mRNA PSA)x1000
- Non-assessable = Associated PSA mRNA <7500 copies/mL
- ≤BLQ = PCA-3 mRNA is below the concentration of the calibrator and associated PSA mRNA >7500 copies/mL
- <35 = PCA-3 mRNA above BLQ and less than 35
- ≥35 = PCA-3 mRNA greater or equal to 35
- PCA3 Score Expressed as a Ratio of PCA3 mRNA Over PSA mRNA [ Time Frame: At month 1 and 3 post-treatment ]
PCA-3 score = (mRNA PCA3/mRNA PSA)x1000
- Non-assessable = Associated PSA mRNA <7500 copies/mL
- ≤BLQ = PCA-3 mRNA is below the concentration of the calibrator and associated PSA mRNA >7500 copies/mL
- <35 = PCA-3 mRNA above BLQ and less than 35
- ≥35 = PCA-3 mRNA greater or equal to 35
- TMPRSS2-ERG Score (Expressed as a Ratio of T2-ERG mRNA Over PSA mRNA) [ Time Frame: At baseline, month 1, 3 and 6 post-treatment ]
TMPRSS2-ERG = (TMPRSS2-ERG mRNA / PSA mRNA) x 100000
A TMPRSS2-ERG score <35 was described as 'negative' and a TMPRSS2-ERG score ≥35 as 'positive.'
- Proportion of Patients Medically Castrated (i.e. With Serum Testosterone Levels of <50 ng/dL) [ Time Frame: At month 1, 3 and 6 post-treatment ]
- PSA Level [ Time Frame: At baseline, month 1, 3 and 6 post-treatment ]
- Safety, Assessed Through the Collection of Adverse Events (AEs) [ Time Frame: For the duration of the study (up to month 6) ]
