Main objective of the trial

The main objective of this study was to evaluate the analgesic efficacy of a single oral dose of fast release aspirin tablets, 650 milligram (mg) (2 × 325 mg) compared to regular aspirin tablets, 650 mg (2 × 325 mg) and placebo in subjects with post-surgical dental pain.

Protection of trial subjects

The conduct of this clinical study met all local legal and regulatory requirements. This study was conducted according to the principles of the International Conference on Harmonisation harmonised tripartite guideline E6(R1): Good Clinical Practice, the World Medical Association Declaration of Helsinki and its most recent amendments, and United States Title 21 of the Code of Federal Regulations Parts 50 and 56 concerning informed consent and Institutional Review Board regulations. Before entering the study, the informed consent form was read by and explained to all subjects and/or their legally authorized representative. Participating subjects signed informed consent form and could withdraw from the study at any time without any disadvantage and without having to provide a reason for this decision. Only investigators qualified by training and experience were selected as appropriate experts to investigate the study drug.

Time to Meaningful Pain Relief

End point description

Meaningful pain relief was defined as when the subject felt the degree of pain relief was meaningful to them. Time to meaningful pain relief was determined by a double-stopwatch measurement using Kaplan -Meier estimate, provided that the subject experienced both “perceptible” and “meaningful” pain relief. Those subjects who do not achieve meaningful pain relief after 6 hours after dosing or those who took rescue medication before experiencing meaningful pain relief was censored in the analysis. '99999' in the below table indicates, the median time to meaningful PR could not be calculated for the placebo group due to timing and number of censored observations.

Pain Intensity Difference (PID) at 10, 20, 30, 40, 50, and 60 minutes and at 2, 3, 4, 5, and 6 hours After Dosing

End point description

Pain intensity was evaluated using a 4-point Categorical Pain Intensity Rating Scale (0 = no pain, 1 = mild pain, 2 = moderate pain, 3 = severe pain) for all pain intensity assessments post-dose. For each post-dose time point, PID was derived by subtracting the pain intensity at the post-dose time point from the baseline intensity score (baseline score – post-baseline score). A positive difference was indicative of improvement.

Summed Pain Intensity Differences (SPID ) from Hour 0 through Hour 2, Hour 4 and Hour 6

End point description

Pain intensity was evaluated using a 4-point categorical Pain Intensity Rating Scale (0 = no pain, 1 = mild pain, 2 = moderate pain, 3 = severe pain) for all pain intensity assessments post-dose. Time-weighted SPID was calculated by multiplying the PID score at each post-dose time point by the duration (in hours) since the preceding time point and then summing these values for 0-2, 0-4, 0-6 hour intervals, respectively. The possible total score ranges of SPIDs are: SPID0-2: 0 to 6, SPID0-4: 0 to 12, SPID0-6: 0 to 18. The higher the SPID value, the more improvement of pain relief.

End point description

Subjects rated pain relief on a 5-point categorical Pain Relief Rating Scale (0 = no relief, 1 = a little relief, 2 = some relief, 3 = a lot of relief, 4 = complete relief). TOTPAR was calculated by multiplying the pain relief score at each post-dose time point by the duration (in hours) since the preceding time point and then summing these values. The possible total score ranges of TOTPARs are: TOTPAR0-2: 0 to 6, TOTPAR0-4: 0 to 12, TOTPAR0-6: 0 to 18. The higher the LS Means scores, the more pain relief was obtained.
