Primary Outcome Measures :
  1. Change in the mean Numerical Rating Scale (NRS) score [ Time Frame: Week 12 ]
    Change from baseline to Week 12 in the weekly mean of the daily Numerical Rating Scale (NRS) score assessing average pain intensity in the past 24 hours


Secondary Outcome Measures :
  1. Patient Global Impression of Change (PGI-C) [ Time Frame: Week 12 ]
    Percentage of subjects "much improved" or "very much improved" on the Patient Global Impression of Change (PGI-C) at Week 12

  2. Daily Sleep Interference (DSIS) score [ Time Frame: Week 12 ]
    Change from baseline in the weekly mean of the Daily Sleep Interference Scale (DSIS) scores at Week 12

  3. Percentage of subjects achieving ≥30% pain reduction [ Time Frame: Week 12 ]
    Percentage of subjects achieving ≥30% reduction from baseline in the weekly mean NRS average pain intensity at Week 12

  4. Percentage of subjects achieving ≥50% pain reduction [ Time Frame: Week 12 ]
    Percentage of subjects achieving ≥50% reduction from baseline in the weekly mean NRS average pain intensity at Week 12

  5. Fibromyalgia Impact Questionnaire-Revised (FIQR) score [ Time Frame: Week 12 ]
    Change from baseline to Week 12 in the Fibromyalgia Impact Questionnaire - Revised (FIQR) score

  6. Patient Reported Outcomes Measurement Information System - Fibromyalgia (PROMIS-FM) sleep disturbance score [ Time Frame: Week 12 ]

  7. Patient Reported Outcomes Measurement Information System - Fibromyalgia (PROMIS-FM) fatigue profile score [ Time Frame: Week 12 ]
    Change from baseline to Week 12 in the PROMIS-FM fatigue profile score

  8. Patient Reported Outcomes Measurement Information System - Fibromyalgia (PROMIS-FM) physical function score [ Time Frame: Week 12 ]
    Change from baseline to Week 12 in the PROMIS-FM physical function score
