Primary Outcome Measures:
  • Cumulative Probability of Testosterone at Castrate Level (≤0.5 ng/mL) With Degarelix [ Time Frame: From Day 28 to Day 364 ]
    This co-primary outcome measure was used to demonstrate that degarelix is effective with respect to achieving and maintaining testosterone suppression to castrate levels, evaluated as the proportion of patients with testosterone suppression ≤0.5 ng/mL from Day 28 to Day 364.

  • Difference in Cumulative Probability of Testosterone at Castrate Level (≤0.5 ng/mL) Between Degarelix and Goserelin [ Time Frame: Day 3 to Day 364 ]
    This co-primary outcome measure was used to establish non-inferiority of degarelix as compared to goserelin with regard to achieving and maintaining testosterone suppression at castrate levels (≤0.5 ng/mL) from Day 3 to Day 364, using a non-inferiority margin of 5 percentage points.

Secondary Outcome Measures:
  • Serum Levels of Testosterone Over Time [ Time Frame: Baseline and after 1, 2, 3, 6 and 13 months ]
    Median testosterone levels are presented as absolute values at Baseline (in Baseline measures) and after 1, 2, 3, 6 and 13 months (below). One treatment month equals 28 days.

  • Percent Change in Serum Levels of Prostate-specific Antigen (PSA) Over Time [ Time Frame: Baseline and after 1, 2, 3, 6 and 13 months ]
    Serum PSA levels are presented as mean percent change from Baseline (in Baseline measures) after 1, 2, 3, 6 and 13 months. One treatment month equals 28 days.

  • Change in Health-related Quality of Life (HRQoL), as Measured by Short Form-36 (SF-36) Score at Month 10 and Month 13 Compared to Baseline [ Time Frame: At baseline, 10 months and 13 months ]
    The SF-36 is a multi-purpose, short-form health survey with only 36 questions and with a minimum score of 0 and a maximum score of 100. The higher score the better health. It yields an 8-scale profile of functional health and well-being scores as well as psychometrically-based physical and mental health summary measures and a preference-based health utility index. The SF-36 has proven useful in surveys of general and specific populations, comparing the relative burden of diseases, and in differentiating the health benefits produced by a wide range of different treatments.

  • Change in International Prostate Symptom Score (IPSS) Score at Months 1, 4, 7, and 13 Compared to Baseline [ Time Frame: At baseline, 1 month, 4 months, 7 months and 13 months ]
    IPSS is used to assess severity of lower urinary tract symptoms and to monitor the progress of symptoms once treatment has been initiated. It contains 7 questions regarding incomplete emptying, frequency, intermittency, urgency, weak stream, straining, and nocturia. Each question is assigned a score of 0-5 (i.e. the minimum total score is 0 and the maximum is 35). A score of "0" corresponds to a response of "not at all" for the first six symptoms and "none" for nocturia, and a score of 5 corresponds to a response of "almost always" for the first six symptoms and "5 times or more" for nocturia.

Enrollment: 859

Study Completion Date: March 2011
Primary Completion Date: March 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Degarelix 240 mg/480 mg Drug: Degarelix
The degarelix doses were administered by subcutaneous (s.c.) injections into the abdominal wall. A starting dose of 240 mg degarelix was administered on Day 0. One month later a maintenance dose of 480 mg was administered. This was repeated after 4, 7, and 10 months (ie a total of 5 administrations).
Other Names:
  • Firmagon
  • FE200486
Active Comparator: Goserelin acetate Drug: Goserelin acetate
The goserelin doses were administered by subcutaneous (s.c.) implants into the abdominal wall. An initial dose of 3.6 mg goserelin was administered on Day 0. One month later a subsequent dose of 10.8 mg was administered and this was repeated after 4, 7, and 10 months (ie a total of 5 implants).
Other Name: Zoladex
