serum PSA [ Time Frame: approximately 15 months ] [ Designated as safety issue: No ]
The study will compare the length of the off treatment interval (in months) of subjects in the 4 month arm vs those in the 10 month arm. The off treatment interval is defined as the time from PSA nadir following completion of hormone therapy in both arms until the time PSA reaches 5.0ng/ml

serum PSA [ Time Frame: at 4 months (4 mon arm) or 10 montths (10 mon arm) ] [ Designated as safety issue: No ]
PSA nadir is described as the serum PSA value after the completion of either 4 months or 10 months of therapy.

Firmagon (Degarelix) Intermittent Therapy
Randomized, Multicentre Efficacy and Safety Study Comparing 10 Mons vs 4 Mons Degarelix Therapy in Prolonging the Off Treatment Interval in Men With Localized Prostate Cancer Receiving Intermittent ADT for Biochemical Recurrence Following Radical Local Therapy
Men with localized prostate cancer requiring intermittent androgen deprivation therapy for biochemical recurrence following radical therapy will be asked to participate in a phase 4 safety and efficacy clinical trial comparing 10 months versus 4 months of degarelix (Firmagon®) therapy with the endpoint of prolonging the off treatment interval.
This is an open-label, multi-centre, randomised trial with subjects receiving subcutaneous (s.c.) monthly injections of degarelix depot. All patients will be treated with a one-month starting dose of 240mg on Day 0. Subjects are then randomized to receive either nine or three maintenance doses of one month duration. The primary objective is to determine the effect of degarelix therapy on the length of the off treatment interval (defined as serum Prostate-specific antigen (PSA) increasing to 5 ng/ml) following completion of the androgen deprivation therapy. The trial will also assess the effect of degarelix therapy on PSA kinetics (specifically PSA doubling time), PSA nadir, and effect on quality of life as well as other measures. The efficacy and safety of these two treatments will also be reported.
Phase 4
Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Prostate Cancer Recurrent
Drug: degarelix
Starting dose of 240 mg (40 mg/mL; injection volume 2 x 3 mL; s.c.) degarelix one-month depot will be administered sc on Day 0, followed by a maintenance dose of 80 mg (20 mg/mL; injection volume 1 x 4 mL; s.c.) sc degarelix one-month depot will be administered into the anterior abdominal wall on Month 1, 2, 3, 4, 5, 6, 7, 8 and 9 for the 10 month arm and month 1, 2 and 3 for the 4 month arm.
