Primary Outcome Measures:
- Time-weighted Sum of Pain Relief Rating and Pain Intensity Difference From 0-8 Hours (SPRID 0-8) [ Time Frame: 0 to 8 hours ] [ Designated as safety issue: No ]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).
- Time to Onset of Meaningful Relief [ Time Frame: 0 to 8 hours ] [ Designated as safety issue: No ]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.
Secondary Outcome Measures:
- Time to Confirmed First Perceptible Relief [ Time Frame: 0 to 8 hours ] [ Designated as safety issue: No ]Participants 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. Stopwatch was active up to 8 hours after dosing or until stopped by the participant, or rescue medication was administered. The first perceptible relief was considered confirmed if the participant also stopped the second stopwatch indicating meaningful relief.
- Pain Relief Rating (PRR) [ Time Frame: 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8 hours ] [ Designated as safety issue: No ]PRR was evaluated at different time points during the study up to 8 hours after taking the study medication, and immediately before rescue medication was taken (if necessary). PRR was assessed on a 5-point categorical pain relief rating scale where 0=No relief to 4=Complete relief.
- Pain Intensity Difference (PID) [ Time Frame: 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8 hours ] [ Designated as safety issue: No ]PID was derived by subtracting the pain severity score at a given post-dosing time point (pain severity score range 0 [none] to 3 [severe]) from the baseline score (Baseline pain severity score range 2 [moderate] to 3 [severe]). Total possible score range for PID: -1 (worst) to 3 (best).
- Sum of Pain Relief Rating and Pain Intensity Difference (PRID) [ Time Frame: 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8 hours ] [ Designated as safety issue: No ]PRID was sum of PID and PRR at each post-dosing time point. The overall possible score range, for PRID was -1 (worst) to 7 (best). PID was derived by subtracting the pain severity score at a given post-dosing time point (pain severity score range 0 [none] to 3 [severe]) from the baseline score (Baseline pain severity score range 2 [moderate] to 3 [severe]). Total possible score range for PID: -1 (worst) to 3 (best). PRR was assessed on 5-point categorical pain relief rating scale (0=No relief to 4=Complete relief).
- Time-weighted Sum of Pain Intensity Difference (SPID) [ Time Frame: 0-2, 0-3, 0-6, 0-8 hours ] [ Designated as safety issue: No ]SPID: time-weighted sum of PID over 2, 3, 6 and 8 hours. SPID scores range was -2 (worst) to 6 (best) for SPID 0-2, -3 (worst) to 9 (best) for SPID 0-3, -6 (worst) to 18 (best) for SPID 0-6, -8 (worst) to 24 (best) for SPID 0-8. 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). Total score range for PID: -1(worst) to 3 (best).
- Time-weighted Sum of Pain Relief Rating (TOTPAR) [ Time Frame: 0-2, 0-3, 0-6, 0-8 hours ] [ Designated as safety issue: No ]TOTPAR: time-weighted sum of PRR scores over 2, 3, 6 and 8 hours. TOTPAR score range was 0 (worst) to 8 (best) for TOTPAR 0-2, 0 (worst) to 12 (best) for TOTPAR 0-3, 0 (worst) to 24 (best) for TOTPAR 0-6, 0 (worst) to 32 (best) for TOTPAR 0-8. PRR was evaluated at different time points during the study up to 8 hours, and immediately after taking rescue medication (if necessary). PRR was assessed on a 5-point categorical pain relief rating scale wherein 0=No relief to 4=Complete relief.
- Time-weighted Sum of Pain Relief Rating and Pain Intensity Difference (SPRID) [ Time Frame: 0-2, 0-3, 0-6, 0-8 hours ] [ Designated as safety issue: No ]SPRID: time-weighted sum of PRID over 2, 3, 6 and 8 hours. SPRID score range:-2 (worst) to 14(best) for SPRID 0-2, -3(worst) to 21(best) for SPRID 0-3, -6(worst) to 42(best) for SPRID 0-6, -8(worst) to 56(best) for SPRID 0-8. PRID:sum of PID and PRR at each time point. Total score range for PRID: -1=worst to 7=best. PID:baseline pain severity score minus pain severity score at given time(score range 0=none to 3=severe; baseline score range 2=moderate to 3=severe). Total score range for PID: -1(worst) to 3(best), PRR: scored on 5-point pain relief rating scale(0=No relief to 4=Complete relief).
- Cumulative Percentage of Participants With Meaningful Relief [ Time Frame: 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8 hours ] [ Designated as safety issue: No ]Percentage of participants with meaningful relief evaluated by stopping the stopwatch labeled 'meaningful relief' at the moment the participant 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.
- Cumulative Percentage of Participants With Confirmed First Perceptible Relief [ Time Frame: 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8 hours ] [ Designated as safety issue: No ]Percentage of participants with first perceptible relief was evaluated by stopping a stopwatch labeled 'first perceptible relief' at the moment the participant first began to experience any relief. Stopwatch was active up to 8 hours after dosing or until stopped by the participant, or rescue medication was administered. The first perceptible relief was considered confirmed if the participant also stopped the second stopwatch indicating meaningful relief.
- Time to Treatment Failure [ Time Frame: 0 to 8 hours ] [ Designated as safety issue: No ]Median time of dropping out of the participants from the study due to lack of efficacy or rescue medication, whichever came first.
- Cumulative Percentage of Participants With Treatment Failure [ Time Frame: 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8 hours ] [ Designated as safety issue: No ]Percentage of participants who withdrew from the study due to lack of efficacy or received rescue medication.
- Cumulative Percentage of Participants With Complete Relief [ Time Frame: 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8 hours ] [ Designated as safety issue: No ]Complete relief was defined as a PRR of 4. PRR was assessed on a 5-point categorical pain relief rating scale where 0=No relief to 4=Complete relief.
- Participant Global Evaluation of Study Medication [ Time Frame: 8 hours ] [ Designated as safety issue: No ]Participant global evaluation of study medication was performed at the 8-hour time point or immediately before taking the rescue medication. It was scored on a 6-point categorical scale where 0 = Very poor, 1 = Poor, 2 = Fair, 3 = Good, 4 = Very Good, and 5 = Excellent.
