A study to investigate ropinirole for treatment of the symptoms of fibromyalgia and in
particular the widespread pain associated with this condition. A total 160 subjects (80 per
treatment arm) are being recruited from approximately 25 centres in 9 European countries.
Male and female subjects greater than 18 years of age with a diagnosis of primary
fibromyalgia, as defined by the American College of Rheumatology (ACR) criteria, are eligible
for study entry. Subjects will receive either ropinirole (1-24mg) or placebo, depending upon
a statistically defined allocation to treatment. The primary endpoint is improvement in pain
score by 12 weeks of treatment. An 11 point numerical rating scale for the assessment of the
subject's pain is being collected on a daily diary. In addition, the overall improvement in
quality of life for the subject will be assessed by means of a number of subject-completed
questionnaires during the treatment period. Safety of the treatment regimen will be assessed
throughout the study.
