A Study of Degarelix in Patients With Prostate Cancer

Phase 3
Completed
Conditions
Prostate Cancer
Interventions
Registration Number
NCT00928434
Lead Sponsor
Ferring Pharmaceuticals
Brief Summary

The purpose of this study was to see if giving Degarelix every month for 7 months then stop treatment for 7 months (intermittent therapy) would show a reduction of negative effects of androgen deprivation therapy by increasing the quality of life while keeping prostate specific antigen (PSA) levels suppressed.

Detailed Description

This was an open-label, randomized, parallel-arm, multicenter study to determine if degarelix intermittent therapy was non-inferior to continuous androgen deprivation therapy (combination of treatment groups receiving continuous degarelix and leuprolide therapy, respectively) in maintaining PSA levels at ≤ 4.0 ng/mL at 14 months.

The study consisted of two phases, Phase A and B. During Phase A, patients in the degarelix intermittent and degarelix continuous arms received 7 months of therapy with degarelix one-month depot formulation and patients in the leuprolide continuous arm received leuprolide one-month depot injection (7.5 mg) followed by two 3-month depot (22.5 mg) injections. After 7 months of treatment, patients with a PSA ≤2 ng/mL continued into Phase B.

During Phase B, patients in the degarelix intermittent arm had a 7-month off-treatment period. Patients randomized to the degarelix continuous arm and the leuprolide continuous arm continued to receive degarelix or leuprolide depot as in Phase A for the remainder of the 14 months.

GroupInterventionDescription
DI (Degarelix Intermittent)DegarelixPatients in this arm received degarelix with a starting dose of 240 mg at a concentration of 40 mg/mL on Day 0 administered subcutaneously (s.c.) into the anterior abdominal wall via two equivalent injections of 120 mg (3 mL) each. Six maintenance doses of degarelix 80 mg per month at a concentration of 20 mg/mL (4 mL) at Days 28 to 168 were administered. During Phase B of the trial, If a patient had Prostate Specific Antigen (PSA) ≥2 ng/mL at any visit, additional doses of degarelix 240 mg followed by 80 mg maintenance dose(s) were administered.
DC (Degarelix Continuous)DegarelixPatients in this arm received degarelix with a starting dose of 240 mg at a concentration of 40 mg/mL administered on Day 0 (Visit 1) s.c. into the anterior abdominal wall via two equivalent injections of 120 mg (3 mL) each. Thirteen maintenance doses of degarelix 80 mg per month at a concentration of 20 mg/mL (4 mL) at Days 28 to 364, administered s.c. into the anterior abdominal wall
LC (Leuprolide Continuous)LeuprolidePatients in this arm received leuprolide 7.5 mg one-month depot injection on Day 0, administered intramuscular (i.m.) into a large muscle, as per manufacturer's labeling directions. One injection of 22.5 mg leuprolide 3-month depot was administered i.m. as per manufacturer's labeling directions at Day 28 and every 3 months afterwards for 4 additional doses (i.e at Days 112, 196, 280, and 364, respectively). On Investigator's discretion, patients in the arm could take bicalutamide (Casodex®) for a maximum of 28 days to alleviate increased signs and symptoms due to initial upsurge in testosterone levels.
