NCT02912650

Brief Summary

This is a randomized, double blind, placebo-controlled, parallel group, single-center study in approximately 560 subjects to determine the overall analgesic efficacy and safety of a fixed-dose ibuprofen 250 mg / acetaminophen 500 mg formulation compared to ibuprofen 250 mg alone, acetaminophen 650 mg alone, and to placebo. Subjects will be healthy males and females aged 18-40 years, inclusive, who are experiencing post-operative pain following surgical extraction of 3 or more third molar teeth. Following extraction, subjects must experience, within 5 hours, post-surgical pain of at least moderate severity (on a 4-point categorical scale), confirmed by a Visual Analog Pain Severity Rating Scale (VAS PSR) of at least 50 mm on a 100 mm VAS PSR scale. Eligible subjects will be randomized to receive a single oral dose of study medication under double-blind conditions and then evaluated on site for 12 hours following administration of study medication. Subjects will provide self-ratings of pain severity and pain relief at various time points using categorical and numerical scales. Additionally, subjects will also evaluate the time to first perceptible relief and time to meaningful relief using a double stopwatch method. Finally, at 12 hours, subjects will complete a categorical Global Evaluation of the study medication. A review of any reported adverse events will also be completed.

Outcome Measures

Primary Outcomes (1)

  • Time-weighted Sum of Pain Intensity Difference Scores on 11-Point Numerical Scale From 0 to 8 Hours Post-dose (SPID11 [0-8])

    Pain intensity was assessed on an 11-point numerical pain severity rating scale. SPID11 (0-8): Time-weighted sum of pain intensity difference (PID) scores over 8 hours. SPID11 score range was -40 (worst score) to 80 (best score) for SPID 0-8. PID was calculated by subtracting the pain intensity score at given post-dose time points (pain severity score range: 0 =no pain to 10 =worst possible pain) from the baseline pain intensity scores (score range: 5 =moderate pain to 10 =worst possible pain; as participants with baseline pain score of at least moderate were included in study). Total possible score range for PID: -5 (worst score) to 10 (best score).

    0 to 8 hours post-dose

Secondary Outcomes (5)

  • Time-weighted Sum of Pain Intensity Difference Scores on 11-Point Numerical Scale From 6 to 8 Hours Post-dose (SPID11 [6-8])

    6 to 8 hours post-dose

  • Time-weighted Sum of Pain Relief Rating (TOTPAR) From 0 to 8 Hours and 6 to 8 Hours Post-dose

    0 to 8 hours, 6 to 8 hours post-dose

  • Time to Treatment Failure

    0 to 12 hours post-dose

  • Cumulative Percentage of Participants With Treatment Failure at 6 and 8 Hours

    6 hours, 8 hours post-dose

  • Time to Onset of Meaningful Pain Relief

    0 to 12 hours post-dose

Other Outcomes (13)

  • Time to Confirmed Onset of First Perceptible Relief

    0 to 12 hours post-dose

  • Pain Relief Rating (PRR) Score

    0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 hours post-dose

  • Pain Intensity Difference on 11-Point Numerical Scale (PID11)

    0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 hours post-dose
