    Outcome Measures

    Primary Outcome Measures

    1. Change From Baseline to 12 Week Endpoint in Brief Pain Inventory 24-hour Average Pain Score [Baseline and 12 weeks]

      A self-reported scale that measures the severity of pain based on the average pain over the past 24-hours. The severity scores range from 0 (no pain) to 10 (pain as severe as you can imagine).

    Secondary Outcome Measures

    1. Change From Baseline to 12 Week Endpoint in Brief Pain Inventory (BPI) Worst Pain, Least Pain, and Current Pain Severity and Average Interference Scores [Baseline and 12 weeks]

      Measures severity of pain and interference of pain on function. Each severity of pain (worst, least, and current) scores range from 0 (no pain) to 10 (pain as severe as you can imagine). The 7 separate Interference item scores range from 0 (does not interfere) to 10 (completely interferes) and were averaged to provide a single score (0 to 10).

    2. Change From Baseline to 12 Week Endpoint in Clinical Global Impression of Severity [Baseline and 12 weeks]

      Measures severity of illness at the time of assessment. Scores range from 1 (normal, not at all ill) to 7 (among the most extremely ill patients.

    3. Time Course of Change in Patient Global Impression - Improvement Scale [baseline, over 12 weeks]

      A scale that measures the patient's perception of improvement at the time of assessment compared with the start of treatment. The score ranges from 1 (very much better) to 7 (very much worse).

    4. Change From Baseline to 12 Week Endpoint in EuroQoL Questionnaire - 5 Dimensions (EQ-5D) (US Based Index Score) [Baseline and 12 weeks]

      The EQ-5D is an assessment of one's overall health. Consists of 5 items. Patients choose 1 of 3 options that best describe the status of each item. The EQ-5D US based index scores range from -0.11 to 1.0 where a score of 1.0 indicates perfect health. A positive change from baseline indicates health improvement.

    5. Number of Participants Discontinuing Due to Adverse Events [over 12 weeks]

    6. Number of Participants With Treatment-Emergent Adverse Events Reported in >5% of Either Treatment Group by Time of Dosing (Morning or Evening) [over 12 weeks]

      Tolerability of morning versus evening dosing, as assessed by the number of participants with spontaneously reported adverse events.

    7. Change From Baseline to 12 Week Endpoint in Athens Insomnia Scale 8-item and 5-item [Baseline and 12 weeks]

      Estimates sleep difficulty. Consists of 8 items rated on a 4-point scale of 0 (no problem at all) to 3 (very serious problem). Total score of the 8-item version (sum of items 1-8) ranges from 0-24, while total score of the 5-item (sum of items 1-5) ranges from 0-15.

    8. Vital Signs - Weight [Baseline and 12 weeks]

      Change from baseline to endpoint in body weight.

    9. Vital Signs - Pulse Rate [Baseline and 12 weeks]

      Change from baseline to endpoint in pulse rate.

    10. Vital Signs - Blood Pressure [Baseline and 12 weeks]

      Change from baseline to endpoint in systolic and diastolic blood pressure.

    11. Statistically Significant Change From Baseline to 12 Week Endpoint in Laboratory Measures - Chloride, High Density Lipoprotein, Sodium, and Triglycerides [Baseline and 12 weeks]

      Significantly different laboratory values between the two groups in baseline to endpoint changes in chloride, high density lipoprotein, sodium, and triglycerides.

    12. Statistically Significant Change From Baseline to 12 Week Endpoint in Laboratory Measures - Uric Acid [Baseline and 12 weeks]

      Significantly different laboratory values between the two groups in baseline to endpoint changes
