Further study details as provided by Abbott:

Primary Outcome Measures:
  • Time-interval weighted sum of pain intensity difference (SPID) using the visual analog scale (VAS) for the 0 to 12 hour interval following study drug administration. [ Time Frame: 12 hours ]
    Sum of pain intensity difference using a 100 mm Visual Analog Scale (VAS)

Secondary Outcome Measures:
  • Time-interval weighted sum of pain relief (TOTPAR) [ Time Frame: 12 hours ]
  • Time-interval weighted sum of pain relief and pain intensity difference (SPRID) [ Time Frame: 12 hours ]
  • Perceptible pain relief [ Time Frame: 12 hours ]
  • Meaningful pain relief [ Time Frame: 12 hours ]
  • Pain relief (PR) [ Time Frame: 12 hours ]
  • Pain intensity (PI) [ Time Frame: 12 hours ]
