The pain intensity difference (PID) at each evaluation time point after the dose of study drug is the difference in pain intensity at the specific evaluation time point and baseline pain intensity \[PID(evaluation time after the first dose) = PI(baseline) - PI(evaluation time after the first dose)\]. A pain intensity score ranging from 0 (no pain) to 10 (worst possible pain) is obtained at baseline and throughout the 12 hour period. The time-weighted SPID12 is the time-weighted summed PID over the 12-hour study period. The scores ranged from -13.75 to 100.5. A negative score indicates an increase in pain intensity and a higher score indicates a greater decrease in pain intensity.
The primary efficacy endpoint is the time-weighted SPID1 evaluated from the patient questionnaire data. Pain intensity (PI) will be measured using an 11-point numerical rating scale (NRS) with 0 (no pain) and 10 (worst possible pain). The patient's rating of PI will be measured at baseline and at 0.25 (15 min), 0.5 (30 min), 0.75 (45 min), 1, 2, 3, 4, and 5 hours following the first dose of study drug. The PID at each evaluation time point after the initiation of the first dose is the difference in PI at the specific evaluation time point and baseline pain intensity \[PID (evaluation time after the first dose) = PI(baseline) - PI(evaluation time after the first dose)\]. The time-weighted SPID1 is the time-weighted summed PID over the 1-hour study period. The observed SPID scores ranged from -.70 to 8.00. A negative score indicates an increase in pain intensity and a positive score indicates a decrease in pain intensity.
The primary outcome measure is the summed pain intensity difference over the 12-hour study period (SPID-12). A pain intensity score ranging from 0 (no pain) to 10 (worst possible pain) is obtained at baseline and throughout the 12 hour study period. The SPID-12 is calculated by summing the difference between baseline pain score and pain score at each assessment time point. The scores after summing could range from -122 to +122. A higher SPID-12 score is better.
