This trial is to investigate the efficacy and safety of rotigotine as compared to placebo in reducing signs and symptoms of fibromyalgia syndrome. The effects of rotigotine on pain, sleep, general activity, mood, and quality of life, and the use of rescue medication to treat pain will be assessed.
The overall post-Baseline duration of treatment was 13 weeks. The trial consisted of a 4-week Titration Phase, an 8-week Maintenance Phase, a 1-week De-escalation Phase, and a 2-week Safety Follow-Up Phase. If subjects met the eligibility criteria, they were randomized to receive rotigotine 4 mg/24 hrs, rotigotine 8 mg/24 hrs, or placebo during the Maintenance Phase. During the 4-week Titration Phase, subjects assigned to rotigotine were titrated at weekly intervals of 2 mg/24 hrs until they reached 4 mg/24 hrs or 8 mg/24 hrs. All subjects who completed the 4-week Titration Phase entered an 8-week Maintenance Phase and were maintained at their randomized dose (rotigotine 4 mg/24 hrs, rotigotine 8 mg/24 hrs, or placebo). No dose adjustment was allowed during the Maintenance Phase. The Treatment Phase was defined as the combined Titration and Maintenance Phases.

Patient Global Impression of Change (PGIC) Assessment From Baseline to the Last Assessment in the 12-week Treatment Phase
The PGIC is a 7-point self-administered categorical rating scale in which the subject rated the change in pain since starting trial medication (from much worse \[score of 1\] to much better \[score of 7\]).

Number of Subjects With Presence of Impulse Control Disorders
Impulse control disorders (ICDs) are a set of psychiatric disorders in which a person is unable to control strong and often harmful impulses. They are assessed in this study using the Jay Modified Minnesota Impulsive Disorders Interview (Jay Modified MIDI), which focuses on the five most common ICDs that may be associated with dopamine agonist use: compulsive buying, compulsive gambling, compulsive eating, hypersexuality and punding (performing repetitive and/or mechanical tasks).
