Prostate Cancer
Conditions
Brief summary
The purpose of this trial was to select a dose of degarelix (FE 200486). Three groups of patients were treated for six months on different doses. The patients had blood samples taken and measured for Testosterone in order to determine the most efficient dose to provide fast and sustained castration. The patients came to the clinic for 16 visits and dependent on the blood sample results they were invited to return for additional blood samples on a two weekly basis.
Detailed description
Degarelix was not FDA regulated at the time of the trial. After completion of the trial degarelix has been approved by the FDA and is thus an FDA regulated intervention.
Interventions
Given as a subcutaneous injection.
