What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline to 12 Week Endpoint in Brief Pain Inventory 24-hour Average Pain Score
Time Frame: 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).
Baseline and 12 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
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
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).
Baseline and 12 weeks
Change From Baseline to 12 Week Endpoint in Clinical Global Impression of Severity
Time Frame: 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.
Baseline and 12 weeks
Time Course of Change in Patient Global Impression - Improvement Scale
Time Frame: 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).
baseline, over 12 weeks
Change From Baseline to 12 Week Endpoint in EuroQoL Questionnaire - 5 Dimensions (EQ-5D) (US Based Index Score)
Time Frame: 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.
Baseline and 12 weeks
Number of Participants Discontinuing Due to Adverse Events
Time Frame: over 12 weeks
over 12 weeks
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
Tolerability of morning versus evening dosing, as assessed by the number of participants with spontaneously reported adverse events.
over 12 weeks
Change From Baseline to 12 Week Endpoint in Athens Insomnia Scale 8-item and 5-item
Time Frame: 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.
Baseline and 12 weeks
Vital Signs - Weight
Time Frame: Baseline and 12 weeks
Change from baseline to endpoint in body weight.
Baseline and 12 weeks

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
