Outcome Measures

Primary Outcomes (2)

• Time-weighted Sum of Pain Relief Rating and Pain Intensity Difference From 0-8 Hours (SPRID 0-8)

  SPRID: time-weighted sum of pain relief rating combined with pain intensity difference (PRID) over 8 hours. SPRID 0-8 score range: -8 (worst) to 56 (best). PRID: sum of Pain intensity differences (PID) and pain relief rating (PRR) at each time point. PRID score range: -1=worst to 7=best. PID: baseline pain severity score minus pain severity score at a given time point (pain severity score range 0=none to 3=severe; baseline score range 2=moderate to 3=severe). PID score range: -1(worst) to 3 (best). PRR: assessed on 5-point pain relief rating scale (0=No relief to 4=Complete relief).

  0 to 8 hours

• Time to Onset of Meaningful Relief

  Participants evaluated the time to meaningful relief by stopping a second stopwatch labeled 'meaningful relief' at the moment they first began to experience meaningful relief. Stopwatch was active up to 8 hours after dosing or until stopped by the participant, or rescue medication was administered.

  0 to 8 hours

Secondary Outcomes (13)

• Time to Confirmed First Perceptible Relief

  0 to 8 hours

• Pain Relief Rating (PRR)

  0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8 hours

• Pain Intensity Difference (PID)

  0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8 hours

• Sum of Pain Relief Rating and Pain Intensity Difference (PRID)

  0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8 hours

• Time-weighted Sum of Pain Intensity Difference (SPID)

  0-2, 0-3, 0-6, 0-8 hours
