Change From Baseline in Average Pain Scores to Week 15/ End of Treatment (EOT) (Including Modified BOCF Data)
Average pain scores are based on pain intensity (11-point Likert-type numerical scale, where 0=no pain and 10=worst possible pain), reported by the subjects in a daily diary. The average pain score for baseline was calculated using the average of the last 7 scores prior to randomization, and the average pain score for Week 15 was computed using the average of the last 7 on-treatment scores prior to Week 15, and they were reported by treatment group.
Time frame: Baseline and Week 15
Responder Rate: Subjects With at Least 30 Percent Reduction in Pain
A responder was a participant with at least 30 percent reduction in average pain scores, using modified BOCF, based on pain intensity (11-point Likert-type numerical scale where 0=no pain and 10=worst possible pain), reported by the subjects in a daily diary. The average pain score for baseline was calculated using the average of the last 7 scores prior to randomization, and the average pain score for Week 15 was computed using the average of the last 7 on-treatment scores prior to Week 15, and they were reported by treatment group.
Time frame: Baseline and Week 15
Responder Rate: Subjects With at Least 50 Percent Reduction in Pain
A responder was a participant with at least 50 percent reduction in average pain scores, using modified BOCF, based on pain intensity (11-point Likert-type numerical scale where 0=no pain and 10=worst possible pain), reported by the subjects in a daily diary. The average pain score for baseline was calculated using the average of the last 7 scores prior to randomization, and the average pain score for Week 15 was computed using the average of the last 7 on-treatment scores prior to Week 15, and they were reported by treatment group.
Time frame: Baseline and Week 15
Change From Baseline in Average Pain Scores by Week
Change from baseline in average pain scores by week based on pain intensity (11-point Likert-type numerical scale where 0=no pain and 10=worst possible pain), reported by the subjects in a daily diary. The average pain scores were calculated as the average of available scores in each week, and were reported by treatment group.
Time frame: Week 1 through Week 16
Change From Baseline to Week 15/EOT in Average Sleep Interference Scores
The average of the last 7 available sleep scores prior to the visit, based on the 11-point Likert-type numerical rating scale for sleep interference (where 0=pain did not interfere with sleep, to 10=pain completely interfered with sleep \[unable to sleep\]), and they were reported by treatment group.

Change From Baseline to Week 15/EOT in HADS Anxiety Subscale Scores (Modified BOCF)
The HADS (Hospital Anxiety and Depression Scale) is a widely used, self-reported, 14-item instrument that measures the presence and severity of anxiety and depression. It consists of 2 subscales; a 7-item anxiety subscale (HADS-A) and a 7-item depression subscale (HADS-D). HADS-A consists of a 7-item scale, each scored on a 4-pt scale (0, 1, 2, or 3), where a higher score indicates worse anxiety. Range of possible HADS anxiety subscale scores is 0 to 21, and normal=(0-7), mild=(8-10), moderate=(11-14), and severe=(15-21).

The HADS (Hospital Anxiety and Depression Scale) is a widely used, self-reported, 14-item instrument that measures the presence and severity of anxiety and depression. It consists of 2 subscales; a 7-item anxiety subscale (HADS-A) and a 7-item depression subscale (HADS-D). HADS-A consists of a 7-item scale, each scored on a 4-pt scale (0, 1, 2, or 3), where a higher score indicates worse anxiety. Range of possible HADS anxiety subscale scores is 0 to 21, and normal=(0-7), mild=(8-10), moderate=(11-14), and severe=(15-21).
