Clinical Trial 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.


Description:

This is a 12-hour, 4-arm, 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 (administered as two caplets of 125 mg/250 mg IBU/APAP) 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, otherwise healthy, 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. Upon completion of the baseline scales, 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. At 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12 hours post dose time points, subjects will provide: self-ratings of pain severity using the numerical and categorical PSRs; and self-ratings of pain relief at each time point using a categorical pain relief rating scale. At 12 hours, subjects will also complete a 6-point categorical Global Evaluation of the study medication. Additionally, subjects will also evaluate the time to first perceptible relief and time to meaningful relief using a double stopwatch method up to 12 hours post-dose or until the time of first rescue medication use, whichever is sooner. A review of any reported adverse events will also be completed.
