Further study details as provided by Pfizer:

Primary Outcome Measures:
  • Pain Intensity Difference (PID) scores (derived from data obtained using the 11 point Likert pain rating scale) [ Time Frame: During each Treatment Phase Visit ]
  • Various pain related assessment [ Time Frame: During each Treatment Phase Visit ]
