Primary Outcome Measures:
  • Average Pain Intensity [ Time Frame: Baseline; last 7 days of 12-week maintenance ] [ Designated as safety issue: No ]
    The primary efficacy endpoint is the change from baseline in the mean of the daily average pain intensity scores (on an 11-point NRS) over the last 7 days of the 12-week maintenance (Week 16).


Secondary Outcome Measures:
  • Change From Baseline in the Mean of the Daily Average Pain Intensity Scores (on an 11-point NRS) Over the Entire 12-week Maintenance [ Time Frame: Baseline, Daily scores over entire 12 week maintenance ] [ Designated as safety issue: No ]
  • Proportion of Subjects Achieving Various Levels of Pain Improvement (Including 30% and 50%) Based on the Percent Change From Baseline to the Last 7 Days of the 12-week Maintenance on an 11-point NRS (Responder Analysis). [ Time Frame: Baseline, Last 7 days of 12-week maintenance ] [ Designated as safety issue: No ]
  • Change From Baseline in the Mean of the Daily Average Pain Intensity Scores (on an 11-point NRS) Over Each Week of Maintenance. [ Time Frame: Baseline; daily scores over each week of maintenance ] [ Designated as safety issue: No ]
  • Change From Baseline of the Weekly Mean of Night Pain Intensity (on an 11-point NRS). [ Time Frame: Baseline; weekly mean ] [ Designated as safety issue: No ]
  • Change From Baseline of the Weekly Mean of Current Pain Intensity (on an 11-point NRS) in the Evening and in the Morning, Respectively. [ Time Frame: Baseline, weekly mean ] [ Designated as safety issue: No ]
  • Brief Pain Inventory Scores: Changes From Baseline to Day 8, Day 15, Day 22, Day 29, Day 43, Day 57, Day 71, Day 85, Day 99, and Day 113 (Final Visit). [ Time Frame: Baseline, weekly mean ] [ Designated as safety issue: No ]
  • Neuropathic Pain Symptoms Inventory: Changes From Baseline to Day 8, Day 15, Day 22, Day 29, Day 43, Day 57, Day 71, Day 85, Day 99 and Day 113 (Final Visit) [ Time Frame: Baseline, weekly mean ] [ Designated as safety issue: No ]
  • Patient Global Impression of Change Using a 7-point Verbal Rating Scale, on Day 29, Day 71 and Day 113 (Final Visit). [ Time Frame: Day 29, Day 71 and Day 113. ] [ Designated as safety issue: No ]
  • Short Form 36 Health Survey (SF-36®): Changes From Baseline to Day 29, Day 71 and Day 113 (Final Visit). [ Time Frame: Baseline, Day 29, Day 71 and Day 113. ] [ Designated as safety issue: No ]
  • EuroQol-5 Dimension Health Questionnaire: Changes From Baseline to Day 29, Day 71 and Day 113 (Final Visit). [ Time Frame: Baseline, Day 29, Day 71 and Day 113. ] [ Designated as safety issue: No ]
  • Assessment of Each Item of the Leeds Sleep Evaluation Questionnaire: Changes From Baseline to Day 29, Day 71 and Day 113 (Final Visit). [ Time Frame: Baseline, Day 29, Day 71 and Day 113. ] [ Designated as safety issue: No ]
  • Hospital Anxiety and Depression Scale: Changes From Baseline to Day 29, Day 71 and Day 113 (Final Visit). [ Time Frame: Baseline, Day 29, Day 71 and Day 113. ] [ Designated as safety issue: No ]
  • Time to Treatment Discontinuation Due to Lack of Efficacy. [ Time Frame: Baseline to time to treatment discontinuation ] [ Designated as safety issue: No ]
  • Assessment of Rescue Medication Usage During the 4-week Titration. [ Time Frame: 4-week titration phase ] [ Designated as safety issue: No ]
