• •13. The subject has a history or current diagnosis of Fibromyalgia, Chronic Fatigue Syndrome, Chronic Pain Syndrome or Sleep apnea (central and/or obstructive). If obstructive sleep apnea is corrected surgically, a polysomnogram showing normal apnea-hypopnea index is required.

• •15. The subject has 1 or more laboratory value outside the normal range, based on the blood or urine samples taken at the Screening Visit, that are considered by the investigator to be clinically significant; or the subject has any of the following values at the Screening Visit:
• •1. A serum creatinine value \>1.5 times the upper limits of normal (xULN).
• •2. A serum total bilirubin value \>1.5 xULN.
• •3. A serum alanine aminotransferase (ALT) or aspartate aminotransferase (AST) value \>2 xULN.
• •16. The subject has glycosylated hemoglobin (HbA1C) ≥7% at screening and no prior diagnosis of diabetes and/or treatment for diabetes. NOTE: Subjects with known diabetes are not excluded.
• •17. The subject has a thyroid stimulating hormone (TSH) value outside the normal range at the Screening Visit that is deemed clinically significant by the investigator. NOTE: Free T4 will be checked if TSH is out of range. If free T4 is abnormal the subject will be excluded.
