Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Baseline Mean Pain Score	This is based on the daily pain dairy and is defined as the baseline mean pain diary score. The Daily Pain Diary consists of an 11-point numeric rating scale (NRS) ranging from 0 ("no pain") to 10 ("worst possible pain"). Subjects describe their pain during the past 24 hours by choosing the appropriate number between 0 and 10.	Baseline
Primary	Change From Baseline to Week 15 in Weekly Mean Pain Score	This is based on the daily pain diary and is defined as the change from baseline to week 15 in mean pain diary score. The Daily Pain Diary consists of an 11-point numeric rating scale (NRS) ranging from 0 ("no pain") to 10 ("worst possible pain"). Subjects describe their pain during the past 24 hours by choosing the appropriate number between 0 and 10.	up to Week 15
Secondary	Patient Global Impression of Change (PGIC) at Week 15	A self administered instrument that measures changes in participants' overall status on a scale ranging from 1 (very much improved) to 7 (very much worse). The PGIC is based on the Clinical Global Impression of Change, which is a validated scale.	Week 15
Secondary	Change From Baseline in Overall Weekly Mean Sleep Interference Score (SIRS)	This is an 11-point NRS ranging from 0 ("pain does not interfere with sleep") to 10 ("pain completely interferes with sleep" [unable to sleep due to pain]). Participants describe how pain has interfered with their sleep during the past 24 hours. Please note that the data for Baseline (raw scores) have been included in the below table to read the change from Baseline data in context.; Note: Weekly mean SIRS scores were derived from the daily sleep diary and calculated as the mean of the available scores in the 7 days. Generally, week 'n' mean SIRS scores were defined as the mean of the 7 daily diary SIRS scores from Day 2+7 (n-1) to Day 1+7*n. For participants with multiple diary scores collected on the same day, the average of all non-missing scores for that day was used in any analyses or data listings.; "Overall" is the pooled average sleep interference score for each subject across all post-baseline/randomization weeks.	up to Week 15
Secondary	Change From Baseline in Pain Severity Index (Brief Pain Inventory-short Form [BPI-sf])	A self-administered questionnaire developed to assess the severity of pain and the impact of pain on daily functions during the 24 hour period prior to evaluation. The BPI-sf consists of 5 questions. Four items measure pain on 11-point response scales from 0 (No Pain) to 10 (Pain as bad as you can imagine). In the above scale, score 0 indicates the better outcome whereas score 10 indicates the worse outcome.	Week 15
Secondary	Change From Baseline in Pain Interference Index (BPI-sf)	BPI-sf is a self-administered questionnaire developed to assess the severity of pain and the impact of pain on daily functions during the 24 hour period prior to evaluation.; It consists of 7 sub-questions that evaluates the level of pain interference with daily functioning on 11-point response scales from 0 (does not interfere) to 10 (completely interferes).; The BPI-sf pain interference index was calculated as average of the seven individual pain interference scores.	Week 15
Secondary	Change From Baseline to Endpoint in Quality of Life Using EuroQol (EQ-5D) Health State Profile Scores	A self-administered questionnaire designed to assess health related quality of life in terms of a single index value or utility score. There are 5 dimensions: mobility, self-care, usual activities, pain/ discomfort, and anxiety/ depression. Each dimension is rated on a 3 point response scale and the scores are combined to form a single index value between 0 and 1 with higher scores being more positive (better health status). The EQ-5D was completed by the subject at week-0 and week-15/ET where 30% responder and 50% responder status would be defined for each participants based on the percent change from baseline (week 0/Randomization) to each visit week in mean pain score and participant global impression of change (PGIC). PGIC is a self-administered instrument that measures change in participant's overall status on a scale ranging from 1 (very much improved) to 7 (very much worse). It is based on the Clinical Global Impression of Change CGIC), which is a validated scale.	Week 15
Secondary	Baseline Scores in the Medical Outcomes Study Sleep Scale (MOS-SS) - Sub-domain Score.	MOS-SS is a self administered measure consisting of twelve items that assess the key constructs of sleep. Instrument scored results in 7 subscales: sleep disturbance, snoring, awaken short of breath or with headache, quantity of sleep, optimal sleep, sleep adequacy, somnolence. Two index measures that assess sleep disturbance was also constructed to provide composite scores.; Sleep disturbance, snoring, somnolence, awaken short of breath, and the 9 items sleep problems index all have score ranges from 0 (no sleep problems) to 100 (greater sleep problems), therefore a negative change indicates improvement.; Sleep adequacy is scored 0 (least sleep adequacy) to 100 (better sleep adequacy), therefore a positive change indicates improvement.; Quantity of sleep is scored 0 (less quantity of sleep) to 24 (greater quantity of sleep), therefore a positive change indicates improvement.; Optimal sleep is scored Yes if average hours of sleep is in range of 7-8 hours.	Baseline
Secondary	Mean Change From Baseline in the Medical Outcomes Study Sleep Scale (MOS-SS) - Sub-domain Score.	MOS-SS is a self administered measure consisting of twelve items that assess the key constructs of sleep. Instrument scored results in 7 subscales: sleep disturbance, snoring, awaken short of breath or with headache, quantity of sleep, optimal sleep, sleep adequacy, somnolence. Two index measures that assess sleep disturbance was also constructed to provide composite scores.; Sleep disturbance, snoring, somnolence, awaken short of breath, and the 9 items sleep problems index all have score ranges from 0 (no sleep problems) to 100 (greater sleep problems), therefore a negative change indicates improvement.; Sleep adequacy is scored 0 (least sleep adequacy) to 100 (better sleep adequacy), therefore a positive change indicates improvement.; Quantity of sleep is scored 0 (less quantity of sleep) to 24 (greater quantity of sleep), therefore a positive change indicates improvement.; Optimal sleep is scored Yes if average hours of sleep is in range of 7-8 hours.	Week 15
Secondary	Percentage of Participants in MOS-SS With Optimal Sleep Status.	MOS-SS optimal sleep status analyzed on a scale of four parameters: any improvements, no change, any worsening and not applicable.	Week 15
Secondary	Percentage of Responders to Treatment With Pregabalin Measured as Reduction in Mean Pain Score of =30%.	Participants with at least 30% reduction in the mean pain score from baseline to each week. Weekly mean pain NRS scores are derived from the daily pain NRS and calculated as the mean of the available scores in the 7 days. Generally, week 'n' mean pain score is defined as the mean of the 7 daily diary pain ratings from Day 2+7*(n-1) to Day 1+7*n. At least 4 entries within the last 7 days are required to calculate a mean score. Scores range from 0 (no pain) to 10 (worst possible pain), with higher scored indicating increased pain.	Week 15
Secondary	Percentage of Responders to Treatment With Pregabalin Measured as Reduction in Mean Pain Score of =50%	Participants with at least 50% reduction in the mean pain score from baseline to each week. Weekly mean pain NRS scores are derived from the daily pain NRS and calculated as the mean of the available scores in the 7 days. Generally, week 'n' mean pain score is defined as the mean of the 7 daily diary pain ratings from Day 2+7*(n-1) to Day 1+7*n. At least 4 entries within the last 7 days are required to calculate a mean score. Scores range from 0 (no pain) to 10 (worst possible pain), with higher scored indicating increased pain.	Week 15
