Primary Outcome Measures:
  • Mean Pain Intensity (NRS) [ Time Frame: 4 Weeks ]
    Numerical Rating Scale, measuring the intensity of pain from 0 to 10, with 0 being no pain and 10 being worst pain imaginable. The comparison of the overall pain intensity, calculated as the mean of the last 7 days on treatment, for each treatment period (V158866 compared to placebo).

  • Safety and Tolerability of V158866 Compared to Placebo [ Time Frame: 4 weeks ]
    Safety and tolerability were measured by occurrence of treatment-emergent adverse events; data represents the number of subjects who experienced treatment-emergent adverse events during each treatment period.
