- Primary Outcome Measures
Name Time Method Change From Baseline in Mean Daily-Average-Pain Score at Week 4 Baseline, Week 4 Change from Baseline in mean daily-average-pain score at week 4. Patients recorded their daily average pain on a 11-point scale (where 0 equals no pain and 10 equals worst pain imaginable) using a diary during the 4-week treatment period. A negative number change from baseline represents a decrease in average pain (improvement).
- Secondary Outcome Measures
Name Time Method Change From Baseline in the Short Form Brief Pain Inventory (SF-BPI) Average Pain Score at Week 4 Baseline, Week 4 Change from baseline in the SF-BPI average pain question score at week 4. The SF-BPI is a patient-rated questionnaire that assesses certain aspects of pain including location, intensity, and interference with certain daily activities. The "average pain" question was rated on an 11-point scale (where 0=no pain and 10=worst pain imaginable). A negative number change from baseline indicates a reduction in average pain.
Change From Baseline in the Fibromyalgia Impact Questionnaire (FIQ) Total Score of Physical Impairment at Week 4 Baseline, Week 4 Change from baseline in FIQ total score of physical impairment at week 4. The FIQ is a disease-specific questionnaire consisting of 10 questions and visual analog scales regarding functional disability, pain intensity, sleep function, stiffness, anxiety, depression, and overall sense of wellbeing. Each question is scored from 0 to 10 with 0 = no impairment (best) and 10 indicates maximum impairment (worst), for a minimum possible score (best) of 0 and a maximum possible (worst) total score of 100. A negative number change from baseline indicates improvement.
Patient Global Impression of Change (PGIC) for Fibromyalgia Syndrome Status at Week 4 Week 4 PGIC status for fibromyalgia syndrome at week 4. The PGIC consists of a self-evaluation by the patient of the overall change of their fibromyalgia syndrome since the beginning of the study, rated on a 7-point scale (score of 1-3 = very much improved to minimally improved; 4= no change; 5-7 = minimally worse to very much worse). Results are presented for the percentage of patients reporting each status: "improved"= score of 1-3; "no change"=score of 4; and "worse"=score of 5-7.
