Primary Outcome Measures:
- Change From Baseline to 12 Week Endpoint in Brief Pain Inventory 24-hour Average Pain Score [ Time Frame: Baseline and 12 weeks ] [ Designated as safety issue: No ]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:
- Change From Baseline to 12 Week Endpoint in Brief Pain Inventory (BPI) Worst Pain, Least Pain, and Current Pain Severity and Average Interference Scores [ Time Frame: Baseline and 12 weeks ] [ Designated as safety issue: No ]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).
- Change From Baseline to 12 Week Endpoint in Clinical Global Impression of Severity [ Time Frame: Baseline and 12 weeks ] [ Designated as safety issue: No ]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.
- Time Course of Change in Patient Global Impression - Improvement Scale [ Time Frame: baseline, over 12 weeks ] [ Designated as safety issue: No ]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).
- Change From Baseline to 12 Week Endpoint in EuroQoL Questionnaire - 5 Dimensions (EQ-5D) (US Based Index Score) [ Time Frame: Baseline and 12 weeks ] [ Designated as safety issue: No ]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.
- Number of Participants Discontinuing Due to Adverse Events [ Time Frame: over 12 weeks ] [ Designated as safety issue: Yes ]
- Number of Participants With Treatment-Emergent Adverse Events Reported in >5% of Either Treatment Group by Time of Dosing (Morning or Evening) [ Time Frame: over 12 weeks ] [ Designated as safety issue: Yes ]Tolerability of morning versus evening dosing, as assessed by the number of participants with spontaneously reported adverse events.
- Change From Baseline to 12 Week Endpoint in Athens Insomnia Scale 8-item and 5-item [ Time Frame: Baseline and 12 weeks ] [ Designated as safety issue: No ]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.
- Vital Signs - Weight [ Time Frame: Baseline and 12 weeks ] [ Designated as safety issue: Yes ]Change from baseline to endpoint in body weight.
- Vital Signs - Pulse Rate [ Time Frame: Baseline and 12 weeks ] [ Designated as safety issue: Yes ]Change from baseline to endpoint in pulse rate.
- Vital Signs - Blood Pressure [ Time Frame: Baseline and 12 weeks ] [ Designated as safety issue: Yes ]Change from baseline to endpoint in systolic and diastolic blood pressure.
- Statistically Significant Change From Baseline to 12 Week Endpoint in Laboratory Measures - Chloride, High Density Lipoprotein, Sodium, and Triglycerides [ Time Frame: Baseline and 12 weeks ] [ Designated as safety issue: Yes ]Significantly different laboratory values between the two groups in baseline to endpoint changes in chloride, high density lipoprotein, sodium, and triglycerides.
- Statistically Significant Change From Baseline to 12 Week Endpoint in Laboratory Measures - Uric Acid [ Time Frame: Baseline and 12 weeks ] [ Designated as safety issue: Yes ]Significantly different laboratory values between the two groups in baseline to endpoint changes
