Reporting Groups
  Description
Degarelix 240/240@40(1-3-6-9) Participants in this arm who completed the main study continued with the same dose (240 mg (40 mg/mL) starting dose and 240 mg (40 mg/mL) at months 1, 3, 6, and 9) in the extension study (240 mg (40 mg/mL) every three months). A protocol amendment in June 2006 changed the dosage to 360 mg or 480 mg (60 mg/mL).
Degarelix 240/240@60(1-3-6-9) Participants in this arm who completed the main study continued with the same dose (240 mg (40 mg/mL) starting dose and 240 mg (60 mg/mL) at months 1, 3, 6, and 9) in the extension study (240 mg (60 mg/mL) every three months). A protocol amendment in June 2006 changed the dosage to 360 mg or 480 mg (60 mg/mL).
Degarelix 240/240@60(1-4-7-10) Participants in this arm who completed the main study continued with the same dose (240 mg (40 mg/mL) starting dose and 240 mg (60 mg/mL) at months 1, 4, 7, 10) in the extension study (240 mg (60 mg/mL) every three months).
