Study Investigating the Pharmacokinetics, Pharmacodynamics and Safety of FE200486

Inclusion Criteria:

Each patient must meet the following inclusion criteria before entry into the study:

Has given written consent before any study related activity is performed (A study related activity is defined as any procedure that would not have been performed during the normal management of the patient.)
Is a male patient with histologically proven adenocarcinoma of the prostate (all stages) in whom endocrine treatment is indicated, except for neoadjuvant hormonal therapy. For patients, prostate-specific antigen (PSA) increases on two consecutive determinations at least 2 weeks apart prior to Visit 1 must be documented.
Is at least 18 years.
Has an ECOG score of 2.
Has a baseline testosterone level within the age specific normal range as measured by the central laboratory.
Has a PSA value of 2 ng/mL as measured by the central laboratory.
Has a life expectancy of at least 6 months.

Exclusion Criteria:

Any patient meeting one or more of the following exclusion criteria will not be entered into the study:

Previous or present hormonal management of prostate cancer (surgical castration or other hormonal manipulation, e.g. GnRH agonists, GnRH antagonists, antiandrogens, estrogens, PC-Spec) except for neoadjuvant hormonal therapy of < 6 months duration and completed > 6 months prior to Visit 1.
Requires hormonal therapy for neoadjuvant purposes.
Is recently (within the last 12 weeks preceding Visit 1) or presently treated with any other drug modifying the testosterone level or function.
Is considered to be a candidate for curative therapy, i.e., radical prostatectomy or radiotherapy within 6 months after Visit 1.
Has a history of severe asthma requiring daily treatment with inhalation steroids, angioedema or anaphylactic reactions.
Has hypersensitivity towards any component of the investigational product.
Has had a cancer disease within the last 10 years except for prostate cancer, and surgically removed basocellular or squamous cell carcinoma of the skin.
Has a clinically significant neurologic, gastrointestinal, renal, hepatic, cardiovascular, psychological, pulmonary, metabolic, endocrine, hematological, dermatological or infectious disorder or any other condition, including excessive alcohol or drug abuse, which may interfere with trial participation, or which may affect the conclusion of the study, as judged by the investigator.
Any clinically significant laboratory abnormalities which, in the judgment of the investigator, would interfere with the patient's participation in this study or evaluation of study results (liver transaminases must be within normal limits).
Has a mental incapacity or language barrier precluding adequate understanding or co-operation.
Has received an investigational drug within the last 12 weeks preceding Visit 1.
Has previously participated in this study.
