Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in Endpoint Mean Pain Score During the Double-blind Treatment Period at Week 14
Time Frame: Baseline, Week 14
|
Assessment of mean pain score was based on participant's daily pain diary.
The daily pain diary consisted of an 11-point numeric rating scale ranging from 0 (no pain) to 10 (worst possible pain).
The participants rated their pain during the past 24 hours by choosing the appropriate number between 0 and 10.
Self-assessment was performed daily at awakening.
The endpoint mean pain score was defined as the mean of the Week 14 pain diary entries in the double-blind treatment phase.
Baseline was defined as the mean of last 7 pain diary entries up to and including Day 1.

Secondary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Percentage of Participants Categorized by Each Patient Global Impression of Change (PGIC) Score at Week 14
Time Frame: Week 14
|
The Patient Global Impression of Change (PGIC) was a participant-rated instrument that measured change in participant's overall status on a scale ranging from 1 (very much improved) to 7 (very much worse), which was based on a validated scale, the Clinical Global Impression of Change (CGIC).
Categories were defined based on the PGIC scores as followed: 1 = very much improved, 2 = much improved, 3 = minimally improved, 4 = no change, 5 = minimally worse, 6 = much worse and 7 = very much worse.

Time Frame: Baseline, Week 14
|
The Fibromyalgia Impact Questionnaire (FIQ) was a 20-item participant-reported outcome instrument designed to assess health status, progress, and outcomes in participants with fibromyalgia.
It contained 10 subscales.
There were 11 questions that are related specifically to physical functioning.
The remaining items assessed pain, fatigue, stiffness, difficulty working, and symptoms of anxiousness and depression.
Score range for each subscale was 0 to 10.
The 10 subscales were combined to yield a total score with range from 0 to 100.
The total score provided an estimation of fibromyalgia impact with higher scores indicating greater impairment.

Self-assessment was performed daily at awakening.
Weekly mean pain score was calculated as mean value of the observations within the window for each week during the double-blind treatment phase.
A participant with at least 30% reduction in weekly mean pain score from baseline to Week 14 was defined as a 30% responder.
