Female subjects must be non-pregnant and non-lactating, and be either postmenopausal (at least 1 year following the last menstrual period), surgically sterilized, or using an appropriate method of contraception. Prior to starting the study, it is strongly recommended that women of childbearing potential use two of the following methods of birth control for at least one month or for whatever amount of time the prescribing doctor determines it will take for the methods of birth control to be fully effective: oral birth control pills, diaphragms, progesterone implanted rods, medroxyprogesterone acetate, or condoms. Women of childbearing potential must have a confirmed negative serum pregnancy test at the Screening visit (V1); 3. Subjects must have personally signed and dated a legally effective written informed consent prior to admission to the study; 4.

At screening (V1), subjects must have a score greater than or equal to 40 mm on the pain Visual Analogue Scale; 6. At randomization (V2/R), at least 4 daily pain diaries must be completed satisfactorily within the last 7 days and the mean daily pain score must be greater than or equal to 4.0 points; 7. At randomization (V2/R), subjects must have a FIQ-Total score greater than or equal to 45 points; 8. Subjects must be willing and able to understand and cooperate with study procedures. |

Evidence of postural hypotension eg, falls in systolic blood pressure of >20 mmHg or diastolic blood pressure >10 mmHg on standing (from supine); 10. Subjects with uncontrolled hypertension; 11. Subjects with a history of transient ischemic attacks, stroke, or the presence of a carotid bruit (unless significant carotid stenosis (>70%) has been ruled out by appropriate investigation); 12. History of chronic hepatitis B or C, acute hepatitis A, B or C within the past 3 months, or HIV infection; 13. Malignancy within the past 2 years with the exception of basal cell carcinoma; 14. Subjects with a history of illicit drug or alcohol abuse within the last 2 years; 15. Subjects with significant hepatic impairment (ie, confirmed AST, ALT or Total Bilirubin >1.5 x ULN); 16. Platelet count <100 × 109/L; white blood cell count <2.5 x 109/L; neutrophil count <1.5 x 109/L; 17. Westergren erythrocyte sedimentation rate (ESR) >40 mm/hr; 18. Abnormal antinuclear antibody (ANA ≥1:160 titre), or rheumatoid factor (RF >80 IU/mL); 19. Subjects taking any other experimental drugs within 30 days prior to screening (V1), or according to local regulation if greater than 30 days; 20. Subjects with active GI disease including any GI surgery that in the opinion of the investigator would interfere with the absorption of study medication; 21. Subjects with difficulties swallowing tablets or unable to tolerate oral medication; 22. Use of prohibited pain/sleep medications (including antidepressants, sedatives, longacting hypnotics, opiates, muscle relaxants; see Table 2, Section 5.5.1) in the absence of appropriate washout periods; 23. Subjects with pending Worker’s Compensation, Workman’s Compensation, civil litigation or disability claims pertinent to the patient’s fibromyalgia; current involvement in out-of-court settlements for claims pertinent to the patient’s fibromyalgia; or currently receiving monetary compensation as a result of any of the above (USA only; for non-US centers-subjects involved in legal cases related to fibromyalgia); 24. A current or recent diagnosis (last 6 months) or episode of major depressive disorder, dysthymia (as diagnosed by M.I.N.I.) and/or uncontrolled depression; 25. History of mania, hypomania, other psychotic disorder, or current mood disorder with psychotic features, as diagnosed by M.I.N.I; 26. Any subjects judged by a mental healthcare professional (a psychiatrist or licensed PhD level clinical psychologist) to be at risk of suicide based on Columbia-Suicide Severity Rating Scale (C-SSRS) and Suicide Behaviors Questionnaire-Revised (SBQ-R) with exclusionary cut-off values for the SBQ-R total score of ≥8 and item-1 score of ≥2; 27. Subjects with serious hepatic, respiratory, hematologic, renal or immunologic illnesses, or unstable cardiovascular disease; 28. Clinically significant or unstable medical or psychological conditions that, in the opinion of the investigator, would compromise participation in the study. |
