Eligibility criteria

Inclusion Criteria:

  • Patients, aged 18 years or older, with a histologically proven prostate cancer of all stages in whom endocrine treatment is indicated.
  • Screening testosterone level above the lower limit of normal range, globally defined as > 2.2 ng/mL.
  • Screening PSA level of =2 ng/mL. ECOG score of =2.
  • Life expectancy of at least one year.

CRITERIA FOR EVALUATION:

Primary endpoint:

  • Probability of testosterone at castrate level (=0.5 ng/mL) from Day 28 through Day 364.

Secondary endpoints:

  • Probability of testosterone at castrate level (=0.5 ng/mL) from Day 56 through Day 364.
  • Serum levels of testosterone, LH, FSH, and PSA over time.
  • Time to PSA failure - defined as two consecutive increases of 50%, and at least 5 ng/mL, compared to nadir.
  • Plasma levels of degarelix over time.
  • Frequency and severity of adverse events.
  • Clinically significant changes in laboratory safety parameters.
  • Clinically significant changes in physical examinations, ECGs, vital signs, and body weight.
