Outcome Measures

Primary Outcomes (1)

  • Average Pain Intensity

    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).

    Baseline; last 7 days of 12-week maintenance

Secondary Outcomes (14)

  • Change From Baseline in the Mean of the Daily Average Pain Intensity Scores (on an 11-point NRS) Over the Entire 12-week Maintenance

    Baseline, Daily scores over entire 12 week maintenance

  • 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).

    Baseline, Last 7 days of 12-week maintenance

  • Change From Baseline in the Mean of the Daily Average Pain Intensity Scores (on an 11-point NRS) Over Each Week of Maintenance.

    Baseline; daily scores over each week of maintenance

  • Change From Baseline of the Weekly Mean of Night Pain Intensity (on an 11-point NRS).

    Baseline; weekly mean

  • Change From Baseline of the Weekly Mean of Current Pain Intensity (on an 11-point NRS) in the Evening and in the Morning, Respectively.

    Baseline, weekly mean
