Primary Outcome Measures
NameTimeMethod
Mean Pain Intensity for "Average Pain Over the Last 24 Hours" ScoreWeek 12

Mean pain intensity for "average pain over the last 24 hours" score (on an 11-point numerical rating scale where 0 = no pain and 10 = pain as bad as you can imagine).

Secondary Outcome Measures
NameTimeMethod
Medical Outcome Study Sleep Scale - Revised (MOS Sleep-R) - Sleep Disturbance SubscaleWeeks 4, 8, and 12

The MOS Sleep-R is a brief, self-administered 12-item assessment designed to measure key aspects of sleep. It includes a sleep problems index and 6 subscales - sleep disturbance, sleep adequacy, daytime somnolence, snoring, awaken short of breath or with headache, and quantity of sleep. The sleep disturbance subscale comprised the responses to questions 1, 3, 7, and 8 on the assessment. The individual responses for each question were recorded on a 5-point scale with options ranging from 1 - "all of the time" to 5 - "none of the time". Sleep disturbance scores were transformed linearly on a scale of 0-100. A higher value indicates a better score; therefore, a higher score indicates a better sleep pattern.

Patient Global Impression of Change (PGIC)Week 12

The PGIC is an ordinal scale which assesses the change in overall status relative to the start of the study. The scale has only 1 item, which measures global change of overall status by the subject on a 7-point scale (very much improved, much improved, minimally improved, no change, minimally worse, much worse, very much worse), where 1 = very much improved and 7 = very much worse. The proportion of subjects responding "very much improved" and "much improved" was summarized by treatment group.

Responder Analysis for Subjects With a ≥ 50% Reduction in Pain Compared to BaselineBaseline to Week 12

A subject's response to treatment was defined as the percentage reduction from the screening mean pain score to the mean pain intensity at week 12 of the double-blind period.

Responder Analysis for Subjects With a ≥ 30% Reduction in Pain Compared to BaselineBaseline to Week 12

A subject's response to treatment was defined as the percentage reduction from the screening mean pain score to the mean pain intensity at week 12 of the double-blind period.
