Primary Outcome Measures:
  • Change From Baseline on the Numeric Rating Scale (NRS) [ Time Frame: Baseline and 8 weeks ] [ Designated as safety issue: No ]
    The primary efficacy variable was the change from baseline on the NRS. The primary time point was the average pain score during the last data-analysis-interval of week 8. The baseline score was the average of the NRS scores across the last 7 days of the screening period (just prior to the start of the placebo run-in). The primary efficacy variable was the pain severity score measured on an 11 point NRS on which 0=no pain and 10=worst possible pain.


Secondary Outcome Measures:
  • Change From Baseline on the Numeric Rating Scale (NRS) in the Treatment of Pain Associated With Fibromyalgia in Adult Female Outpatients [ Time Frame: Baseline and 8 weeks ] [ Designated as safety issue: No ]
    The efficacy variable was the change from baseline on the numeric rating scale (NRS). The time point was the average pain score during the last data-analysis-interval of week 8, data analysis interval. The baseline score was the average of the NRS scores across the last 7 days of the screening period (just prior to the start of the placebo run-in). The efficacy variable was the pain severity score measured on an 11 point NRS on which 0=no pain and 10=worst possible pain.
