Design outcomes

Primary

MeasureTime frameDescription
Total Pain Relief (TOTPAR) Score From 0 to 6 Hours0 to 6 hoursTOTPAR \[6\] was defined as the area under the pain relief (PR) curve through the first 6 hours after dosing. Area under the curve (AUC) was calculated using the trapezoid rule with PR was assumed to be 0 at time=0. PR assessed on a 5-point categorical scale; 0 (none), 1 (a little), 2 (some), 3 (a lot) and 4 (complete), at 15, 30, 45, minutes and at different time points during the study up to 6 hours post-dose. Total score range for TOTPAR \[6\]: 0 (worst) - 24 (best), higher value of TOTPAR indicated greater degree of PR.

Secondary

MeasureTime frameDescription
Time-specific Pain Relief (PR) Score0, 15, 30, 45 minutes, 1, 1.5, 2, 3, 4, 6, 8, 24 hours, prior to rescue medication (RM)PR was assessed on a 5-point categorical scale; 0 (none), 1 (a little), 2 (some), 3 (a lot) and 4 (complete) at each relevant time points.
Time-specific Pain Intensity Difference (PID) Score15, 30, 45 minutes, 1, 1.5, 2, 3, 4, 6, 8, 24 hours, prior to RMPain intensity was assessed on a categorical scale ranging from 0 (none), 1 (mild), 2 (moderate) and 3 (severe). PID was calculated as pain intensity at baseline minus pain intensity at the respective post-baseline visit.
Summed Pain Intensity Difference (SPID) Score at 6 Hours and 24 Hours0 to 6, 0 to 24 hoursPain intensity was assessed on a categorical scale ranging from 0 (none), 1 (mild), 2 (moderate) and 3 (severe). PID was calculated as pain intensity at baseline minus pain intensity at the respective post-baseline visit. The SPID at 6 and 24 hours was derived by calculating the area under the PID effect curve through the first 6 or 24 hours post-dose respectively. The AUC was calculated using the trapezoid rule. Total score range: -6 (worst) to 18 (best) for SPID 0-6, and -24 (worst) to 72 (best) for SPID 0-24. Higher value of SPID indicated greater degree of pain relief.
Total Pain Relief (TOTPAR) Score From 0 to 24 Hours0 to 24 hoursTOTPAR \[24\] was defined as the area under the pain relief (PR) curve through the 24 hours after dosing. Area under the curve (AUC) was calculated using the trapezoid rule with PR assumed to be 0 at time=0. PR was assessed on a 5-point categorical scale; 0 (none), 1 (a little), 2 (some), 3 (a lot) and 4 (complete), at 15, 30, 45, minutes and at different time points during the study up to 24 hours post-dose. Total score range for TOTPAR \[24\]: 0 (worst) - 96 (best), higher value of TOTPAR indicated greater degree of PR.
Time to Onset of First Perceptible Pain Relief (PR)0 to 24 hoursParticipants evaluated the time to first perceptible relief by stopping a stopwatch labeled 'first perceptible relief' at the moment they first began to experience any relief.
Time to Onset of First Meaningful Pain Relief (PR)0 to 24 hoursParticipants evaluated the time to first meaningful relief by stopping a second stopwatch labeled 'meaningful relief' at the moment they first began to experience meaningful relief.
Time to First Use of Rescue Medication1.5 to 24 hoursTime to first use of rescue medication (2 tablets of acetaminophen 500 mg as starting dose) was calculated by subtracting time of first administration of study medication from the rescue medication administration time.
Number of Participants With Rescue Medication0 to 24 hoursParticipants who did not experience adequate pain relief after 90 minutes post-dose of study medication had received 2 tablets of acetaminophen 500 mg as rescue medication.
Participant Global Evaluation of Study Medication6, 24 hours, prior to RMParticipant rated the study medication that they received during the study, at both the 6 hour and 24 hour observations or at time of rescue medication, whichever occurs first, by answering the following question on 6-point categorical scale: how would you rate the study medication you received for pain? 5=excellent, 4=very good, 3=good, 2=fair and 1=poor.
Participant Satisfaction Questionnaire6, 24 hours, prior to RMParticipant's response to 2 questions about how satisfied or dissatisfied they were with the study medication for PR and overall performance (OP) was obtained on a 5 point categorical scale, 1=very dissatisfied, 2=somewhat dissatisfied, 3=neither satisfied nor dissatisfied, 4=somewhat satisfied and 5=very satisfied.

Total Pain Relief (TOTPAR) Score From 0 to 6 Hours

TOTPAR \[6\] was defined as the area under the pain relief (PR) curve through the first 6 hours after dosing. Area under the curve (AUC) was calculated using the trapezoid rule with PR was assumed to be 0 at time=0. PR assessed on a 5-point categorical scale; 0 (none), 1 (a little), 2 (some), 3 (a lot) and 4 (complete), at 15, 30, 45, minutes and at different time points during the study up to 6 hours post-dose. Total score range for TOTPAR \[6\]: 0 (worst) - 24 (best), higher value of TOTPAR indicated greater degree of PR.

Time frame: 0 to 6 hours

Population: Full analysis set (FAS) included all randomized participants who had received at least 1 dose of study treatment and not received rescue medication of any type in the first 90 minutes following treatment administration. Missing PR values were imputed using last observation carried forward (LOCF).

Summed Pain Intensity Difference (SPID) Score at 6 Hours and 24 Hours

Pain intensity was assessed on a categorical scale ranging from 0 (none), 1 (mild), 2 (moderate) and 3 (severe). PID was calculated as pain intensity at baseline minus pain intensity at the respective post-baseline visit. The SPID at 6 and 24 hours was derived by calculating the area under the PID effect curve through the first 6 or 24 hours post-dose respectively. The AUC was calculated using the trapezoid rule. Total score range: -6 (worst) to 18 (best) for SPID 0-6, and -24 (worst) to 72 (best) for SPID 0-24. Higher value of SPID indicated greater degree of pain relief.

Time frame: 0 to 6, 0 to 24 hours

Population: FAS included all randomized participants who had received at least 1 dose of study treatment and not received rescue medication of any type in the first 90 minutes following treatment administration. Missing SPID values were imputed using LOCF.

Supine Systolic and Diastolic Blood Pressure (BP)

Supine systolic and diastolic BP was measured after the participant has been rested in the supine position for at least 5 minutes with the participant's arm supported at the level of the heart, and recorded to the nearest millimeters of mercury (mmHg). The same arm and position and same size BP cuff was used throughout the study.

Total Pain Relief (TOTPAR) Score From 0 to 24 Hours

TOTPAR \[24\] was defined as the area under the pain relief (PR) curve through the 24 hours after dosing. Area under the curve (AUC) was calculated using the trapezoid rule with PR assumed to be 0 at time=0. PR was assessed on a 5-point categorical scale; 0 (none), 1 (a little), 2 (some), 3 (a lot) and 4 (complete), at 15, 30, 45, minutes and at different time points during the study up to 24 hours post-dose. Total score range for TOTPAR \[24\]: 0 (worst) - 96 (best), higher value of TOTPAR indicated greater degree of PR.

Time frame: 0 to 24 hours

Population: FAS included all randomized participants who had received at least 1 dose of study treatment and not received rescue medication of any type in the first 90 minutes following treatment administration. Missing TOTPAR values were imputed using LOCF.
