- Mean Pain Intensity for "Average Pain Over the Last 24 Hours" Score [ Time Frame: Week 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).
- Medical Outcome Study Sleep Scale - Revised (MOS Sleep-R) [ Time Frame: Weeks 4, 8, and 12 ]The scale consists of 12 individual items categorized into a sleep problems index and 6 subscales: 4 sleep disturbance, 2 sleep adequacy, 1 quantity of sleep, 3 daytime somnolence, 1 snoring, 1 shortness of breath. Scores range from 0 to 100, where higher scores indicate greater sleep disturbance.
- Patient Global Impression of Change (PGIC) [ Time Frame: Week 12 ]The PGIC observational scale was completed by the subject. Subjects were asked to assess 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 "much improved" and "very much improved" was summarized by treatment group and compared between groups using an exact test.
- Responder Analysis for Subjects With a ≥ 30% Reduction in Pain Compared to Baseline [ Time Frame: 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 ≥ 50% Reduction in Pain Compared to Baseline [ Time Frame: 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.
