A Randomised, Parallel-arm, Open-label Trial Comparing Degarelix With Goserelin Plus Anti-androgen Flare Protection (Bicalutamide), in Terms of Volume Reduction of the Prostate in Patients With Prostate Cancer Being Candidates for Medical Castration
In Brief
A Phase 3 clinical trial evaluating Degarelix, Goserelin, and 1 other intervention for Prostate Cancer. Completed, enrolled 182 participants across 46 sites in 8 countries.
Detailed Summary
This was a Phase 3b clinical study in prostate cancer patients which aimed to compare the current standard therapy of a gonadotrophin releasing hormone (GnRH) agonist, goserelin (3.6 mg; plus anti-androgen flare protection, bicalutamide), to a novel GnRH antagonist, degarelix (240 mg starting dose/80 mg maintenance dose) with respect to mean percentage reduction in prostate volume. The hypothesis was that degarelix could decrease prostate size at least as effectively as the combination of a GnRH agonist with an anti-androgen for flare protection.

Interventions
The degarelix doses were administered into the abdominal wall every 28 days. A starting dose of 240 mg (40 mg/mL) degarelix was administered on Day 0 as two 3 mL subcutaneous (s.c.) injections. The second and third doses of 80 mg (20 mg/mL) degarelix were administered as single 4 mL s.c. injections on Days 28 and 56, respectively.
Goserelin implants (3.6 mg) were inserted s.c. into the abdominal wall every 28 days. The first dose was administered on Day 0. The second and third doses of goserelin were administered on Days 28 and 56, respectively.
On Day 0, participants began once-daily per-oral (p.o.) treatment with bicalutamide (50 mg) as anti-androgen flare protection; this treatment continued for 28 days after the first dose of goserelin.
