Endothelial Function in Prostate Cancer Patients on Degarelix vs. Luteinizing Hormone-Releasing Hormone Agonists
Endothelial Function in Prostate Cancer Patients on Degarelix vs. Luteinizing Hormone-Releasing Hormone Agonists
The purpose of this study is to test whether Degarelix is associated with less endothelial
 dysfunction (an intermediate in the development of cardiac disease) and cardiovascular
 biomarkers compared to LHRH agonists.
This is a national multicenter randomized open-label superiority study of the use of
 Degarelix compared to LHRH agonists among men with advanced prostate cancer and pre-existing
 cardiovascular disease. Patients will be stratified based on baseline endothelial function
 and presence prostate cancer metastasis.

 Study population: Subjects with pre-existing cardiovascular disease with locally advanced or
 metastatic prostate cancer and scheduled to start Androgen Deprivation Therapy (ADT).
 Patients already on ADT will be excluded. subjects will receive either two initial loading
 doses of 120mg Degarelix for 1 month followed by 80mg monthly for eleven additional months or
 an LHRH agonist at the discretion of the treating Urologist/Oncologist for 1 year. Follow-up
 visits will occur every 3 months. A blood sample for Prostate-specific antigen (PSA), cardiac
 biomarkers and rectal examination will be performed each visit. At baseline 6 and 12 months
 EndoPAT2000 measurements will be taken.
Inclusion Criteria:

 -  Male patients with locally advanced or metastatic prostate cancer or high-risk
 prostate cancer.

 -  Scheduled to start ADT for a period of at least one year.

 -  Subject has a history of one or more of the following:

 1. Myocardial infarction

 2. Ischaemic or Haemorrhagic cerebrovascular conditions

 3. Arterial embolic and thrombotic events,

 4. Ischaemic heart disease

 5. Prior coronary artery or iliofemoral artery revascularization (percutaneous or
 surgical procedures)

 6. Peripheral vascular disease (e.g. significant stenosis (ABPI<0.9), claudication,
 prior vascular surgery/intervention)

 -  Life expectancy of over 12 months.

 -  WHO performance status of 0-2

 -  Subject is able and has agreed to sign a consent form.

 Exclusion Criteria:

 -  Prior use of ADT. However, prior use of anti-androgens such as Casodex, Chimax,
 Drogenil, and Cyprostat will be allowed.

 -  Prior use of dutasteride/finasteride in past 6 months

 -  Known allergic reaction to Degarelix.

 -  Any psychological, familial, sociological or geographical situation potentially
 hampering compliance with the study protocol and follow-up schedule.
