Exclusion Criteria:

* Have brain metastases
* Have vertebral metastases with evidence of spinal cord compression
* Have renal impairment due to ureteric obstruction or a history of obstructive uropathy
* Have excruciating, sever bone pain due to extensive bone metastases (however, concomitant therapy with either flutamide or bicalutamide is permitted and encouraged during the first month of the study, in the case where mile bone metastasis are present or suspected)
* Undergone orchiectomy, adrenalectomy or hypophysectomy
* Have undergone prostatic surgical procedures (e.g. radical prostatectomy, transurethral resection of the prostate) within the last month
* Have undergone localized external beam radiotherapy, brachytherapy, thermotherapy or cryotherapy within the last 4 weeks
* Undergone systemic chemotherapy, immunotherapy (e.g. antibody therapies, tumor-vaccines) or biological response modifiers (e.g. cytokines) within the last 3 months
* Have been treated with 5-alpha-reductase inhibitors (e.g finasteride (Proscar®, Propecia®), dutasteride (Avodart®)) within the last month
* Have been previously treated with luteinizing hormone releasing hormone agonists (LHRHa) (e.g. leuprolide (Lupron®), goserelin (Zoladex®) etc.) except if their testosterone levels are above 5 nmol/L and the patient in a known responder
* Have and ongoing treatment with androgen receptor (AR) blockers (e.g. megestrol (Megace®) or cyproterone (Androcur®). Note: Treatment with bicalutamide (Casodex®) IS permitted.
* Have a known hypersensitivity to gonadotropin releasing hormone (GnRH), GnRH agonists, any Luteinizing Hormone-Releasing Hormone (LHRH) agonists (e.g. leuprolide (Lupron®), goserelin (Zoladex®) etc.) or to the poly(lactic-co-glycolic acid (PLGA)) polymers contained in the study formulation

* Have received an investigational drug or participated in a clinical trial within the last 30 days
* Have a clinically serious and/or unstable intercurrent infection, medical illnesses or conditions that are uncontrolled or whose control, in the opinion of the Investigator, may be jeopardized by participation in this study or by the complications of this therapy
* Have a body mass index (BMI) \< 18.5
* Be an anticoagulated patient with an International Normalized Ratio (INR) ≥ 2
