Ferring Pharmaceuticals
  Purpose
The purpose of the trial was to evaluate the safety and efficacy of degarelix when comparing six different doses. The patients participating in the trial were treated with degarelix every month for a year. During the treatment the patients had to visit the clinic for investigations. Blood samples for testosterone, dihydrotestosterone, luteinizing hormone, follicle stimulating hormone, and Prostate Specific Antigen were taken and analysed throughout the trial.

Condition Intervention Phase
Prostate Cancer Drug: degarelix Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open-label, Randomised, Multi-centre, Parallel Group Comparison of the Efficacy and Safety of Degarelix at Six Different Dosing Regimens in Patients With Prostate Cancer Treated for 12 Months

Primary Outcome Measures:
  • Number of Patients With Testosterone <=0.5 Nanograms/Milliliter From Day 28 to Day 364 [ Time Frame: 12 months ]
    Number of patients who achieved a testosterone level considered a castration level.


Secondary Outcome Measures:
  • Number of Patients With Testosterone Level <=0.5 Nanogram/Milliliter From Day 28 to Day 364 for Patients With Testosterone <=0.5 Nanogram/Milliliter at Day 28 [ Time Frame: Day 28 - 364 ]
    Number of patients who maintained a castration level of testosterone (<=0.5 Nanogram/Milliliter) while on a maintenance dose of Degarelix from Day 28 - 364.

  • Number of Patients With Testosterone <=0.5 Nanogram/Milliliter at Day 28. [ Time Frame: Day 28 ]
    The number of patients who achieved the <=0.5 nanogram/milliliter level for serum testosterone after the initial dose cycle.

  • Number of Patients With Testoterone <=0.5 Nanogram/Milliliter at Day 3. [ Time Frame: Day 3 ]
    The number of patients who achieved the <=0.5 nanogram/milliliter level for serum testosterone after 3 days.

  • Days to 50 Percent Reduction in Prostate-Specific Antigen [ Time Frame: Day 0 (post dose) to Day 364 ]
    Median number of days after the first dose of Degarelix when the prostate-specific antigen levels fell to 50 percent of the baseline value.

  • Days to 90 Percent Reduction in Prostate-Specific Antigen [ Time Frame: Day 0 (post dose) to Day 364 ]
    Median number of days after the first dose of Degarelix when the prostate-specific antigen levels fell to 90 percent of the baseline value.

  • Days to Prostate-Specific Antigen Progression [ Time Frame: Day 0 (post dose) to Day 364 ]
    Median days to prostate-specific antigen increase of >= 50 percent and >=5 nanograms/milliliter compared to nadir on two consecutive visits at least two weeks apart.

  • Median Serum Testosterone Levels [ Time Frame: Day 0 (Baseline), Days 1,3,7,14, and 364 ]
  • Median Prostate-specific Antigen Levels [ Time Frame: Day 0 (Baseline), Days 3, 7, 14, and 364 ]
  • Median Values of Di-Hydrotestosterone [ Time Frame: Day 0 (Baseline), Days 1, 3, 7, 14, and 364 ]
  • Median Values for Serum Luteinizing Hormone [ Time Frame: Day 0 (Baseline), Days 1, 3, 7, 14, and 364 ]
  • Median Values for Follicle Stimulation Hormone [ Time Frame: Day 0 (Baseline), Days 1, 3, 7, 14, and 364 ]
  • The Number of Patients With Abnormal Liver Function Tests [ Time Frame: 364 days ]
    The number of patients who had abnormal (defined as above upper limit of normal range(ULN)) alanine aminotransferase(ALT), aspartate aminotransferase levels, and bilirubin levels. Also includes the number of patients who had ALT increases >3x ULN, and patients with ALT increases >3x ULN with concurrent increases in bilirubin >1.5 ULN.

  • The Number of Patients With Markedly Abnormal Changes in Vital Signs or Body Weight [ Time Frame: Day 364 ]
    Vital sign and body weight values at the end of the trial are compared to baseline values. The table represents the number of patients in each group with normal baseline values and markedly abnormal end-of-study values.
