Purpose
This Phase IV observational trial is intended to identify patients who are failing GnRH agonist therapy as evidenced by a rising PSA and who have yet to initiate secondary manoeuvres involving antiandrogens. This group may include both non-metastatic as well as metastatic patients. The trial will determine if these patients will benefit from switching to Degarelix. It will assess the effect of Degarelix's direct mode of action on androgen levels and whether continuous use of Degarelix improves disease progression.
As per the CUA Guidelines for the Management of CRPC, because the androgen receptor remains active in most patients who have developed castration resistant disease, it is recommended that ADT should be continued (LEVEL 3, GRADE C). Therefore, it is logical to continue patients on Degarelix throughout the castrate resistant period. This will allow for the gathering of data that is currently unknown within this setting, such as the effect of combined treatment with antiandrogens as well as chemotherapy and other castrate resistant treatments.

- Testosterone Suppression [ Time Frame: Two Years after first dose of degarelix. ] [ Designated as safety issue: No ]To evaluate testosterone supression in hormone sensitive prostate cancer patients switched to Degarelix therapy after failing on GnRH agonists
- Hormone Levels [ Time Frame: Two Years after first dose of degarelix. ] [ Designated as safety issue: No ]To evaluate testosterone, bio available testosterone (calculated), prostate serum antigen (PSA), luteinizing hormone (LH) , follicle-stimulating hormone (FSH), dihydrotestosterone (DHT) and dehydroepiandrosterone (DHEA) before and after switching to Degarelix and over time
- PSA Response [ Time Frame: Two Years after first dose of degarelix. ] [ Designated as safety issue: No ]To evaluate PSA response (ability of Degarelix to stabilise or reverse PSA progression)
- PSA Failure [ Time Frame: Two Years after first dose of degarelix. ] [ Designated as safety issue: No ]To evaluate how long patients are on degeralix prior to demonstrating biochemical disease progression (time to PSA failure)
- PSA Doubling Time [ Time Frame: Two Years after first dose of degarelix. ] [ Designated as safety issue: No ]To evaluate PSA doubling time.
- Time to Metastases [ Time Frame: Two Years after first dose of degarelix. ] [ Designated as safety issue: No ]To evaluate how long patients are on degeralix before they develop metastases (non-metastatic patients)
- Time to Chemotherapy [ Time Frame: Two Years after first dose of degarelix. ] [ Designated as safety issue: No ]Eevaluate how long patients have been on degeralix before initiating chemotherapy.
- Time to Anti-Androgen use [ Time Frame: Two Years after first dose of degarelix. ] [ Designated as safety issue: No ]Evaluate how long patients are on degeralix before initiating anti-androgen use as well as response to anti-androgen use
- Patient Performance Status [ Time Frame: Two Years after first dose of degarelix. ] [ Designated as safety issue: No ]To evaluate patient performance status as defined by the Eastern Cooperative Oncology Group (ECOG).

Detailed Description:
This trial will include hormone sensitive prostate cancer patients switched to Degarelix therapy after failing on GnRH agonists but prior to use of secondary hormonal treatments such as antiandrogens. The purpose of this trial is to determine the effect of Degarelix's direct mode of action on androgen levels and whether continuous use of Degarelix improves disease progression.
This is an open-label, multi-centre, Phase IV observational trial with s.c. injections of Degarelix one-month depot in patients with advanced prostate cancer.
The visit frequency is once a month (28-day intervals), with eCRF data entry at every 4 months. All patients will be treated with a one-month starting dose followed by 23 monthly maintenance doses for a duration of 672 days. The primary endpoints will be evaluated after 24 treatment months.
In total, 25 visits are scheduled for all patients.
