Current Primary Outcome Measures  ICMJE
 (submitted: February 22, 2018)
  • Time-weighted Sum of Pain Intensity Difference Score From 0 to 12 Hours (SPID 0-12) [ Time Frame: Baseline (0 hour) to 12 hours post dose ]
    Pain intensity difference (PID) score based on 4-point categorical pain intensity rating scale. Participants asked, "How much pain do you have at this time?" Range of scale: None (0), Mild (1), Moderate (2), Severe (3). SPID derived by adding the time-weighted sums of PID scores over the time interval. Scores could range from -12 to 36 where higher positive values indicated improvement (decrease in pain intensity).
  • Time-weighted Sum of Pain Intensity Difference Score From 8 to 12 Hours (SPID 8-12) [ Time Frame: 8 to 12 hours post dose ]
    PID score based on 4-point categorical pain intensity rating scale. Participants asked, "How much pain do you have at this time?" Range of scale: None (0), Mild (1), Moderate (2), Severe (3). SPID score derived by adding the time-weighted sums of PID scores over the time interval. Scores could range from -4 to 12 where higher positive values indicated improvement (decrease in pain intensity).
Original Primary Outcome Measures  ICMJE
 (submitted: June 3, 2009)
SPID 0-12 (time weighted sum of pain intensity difference scores from 0-12 hrs) AND SPID 8-12 (time-weighted sum of pain intensity difference scores from 8-12 hrs) [ Time Frame: 24-hours ]

Current Secondary Outcome Measures  ICMJE
 (submitted: February 22, 2018)
  • Time to First Perceptible Pain Relief [ Time Frame: Baseline to 6 hours ]
    Time to first perceptible relief (confirmed by meaningful relief) was defined as the elapsed time from dosing until the participant depresses the first stopwatch labelled "first perceptible relief", if the participant also depressed the second stopwatch labelled as "meaningful relief" by 6 hours. If the confirmation was not achieved, the participant was censored at 6 hours. Perceptible relief defined as when participant first begins to feel any pain relieving effect whatsoever of the drug. Does not necessarily mean the participant feels completely better, but when the participant first feels any difference in the pain he/she has currently.
  • Time to Treatment Failure [ Time Frame: Baseline to 24 hours ]
    Time to first rescue medication or discontinuation due to lack of efficacy
  • Percentage of Participants With Treatment Failure [ Time Frame: 8, 9, 10, 11, and 12 hours ]
    Treatment failure defined as use of rescue medication or discontinuation due to lack of efficacy.
  • Time-weighted Sum of Pain Intensity Difference From 0 to 4 Hours (SPID 0-4) and 4 to 8 Hours (SPID 4-8) [ Time Frame: 0 to 4 hours and 4 to 8 hours ]
    Time-weighted sum of PID score. PID based on 4-point categorical pain intensity rating scale. Participants asked, "How much pain do you have at this time?" Range of scale: None (0), Mild (1), Moderate (2), Severe (3). SPID score derived by adding the time-weighted sums of PID scores over the time interval. Scores could range from -4 to 12 where higher positive values indicated improvement (decrease in pain intensity).
  • Time-weighted Sum of Pain Relief and Pain Intensity Difference Scores (SPRID) [ Time Frame: 0 to 4 hours, 4 to 8 hours, 8 to 12 hours, and 0 to 12 hours ]
    Time-weighted sum of PRID score where PRID=PID+PR. PID: 4-point categorical pain intensity difference scale, 0 (none) to 3 (severe), score derived by subtracting postdose score from baseline, ranged from -1 to 3. Baseline pain intensity score of at least 2 required for enrollment. Higher positive PID values = improvement. PR: 5-point categorical pain relief scale None (0), A Little (1), Some (2), A Lot (3) or Complete (4). SPRID 0-4, SPRID 4-8, and SRID 8-12 scores ranged from -4 to 28, SPRID 0-12 ranged from -12 to 84, higher scores = greater improvement.
  • Time-weighted Sum of Pain Relief Scores (TOTPAR) [ Time Frame: 0 to 4 hours, 4 to 8 hours, 8 to 12 hours, and 0 to 12 hours ]
    TOTPAR based on 5-point categorical pain relief scale. Participants asked, "How much relief do you have from your starting pain?" Range of scale: None (0), A Little (1), Some (2), A Lot (3) or Complete (4). Higher scores indicated improvement (better pain relief). For time-weighted sum of pain relief scores from 0 to 4 hours (TOTPAR 0-4), from 4 to 8 hours (TOTPAR 4-8), and from 8 to 12 hours (TOTPAR 8-12): range of scores 0 (worst) to 16 (best). TOTPAR 0-12 range of scores 0 (worst) to 48 (best).
  • Percentage of Participants Achieving First Perceptible Relief Confirmed by Meaningful Relief [ Time Frame: 15, 30, 45, 60, 90, and 120 minutes and every 60 minutes up to 360 minutes ]
    The elapsed time from dosing until the participant indicated first perceptible relief, provided the participant also indicated achieving meaningful relief. Perceptible relief defined as when participant first begins to feel any pain-relieving effect whatsoever of the drug. Does not necessarily mean the participant feels completely better, but when the participant first feels any difference in the pain he/she currently has now.
  • Time to Meaningful Pain Relief [ Time Frame: Baseline to 6 hours ]
    Participants evaluated the time to meaningful relief by depressing a second stopwatch at the moment they first began to experience meaningful relief, defined as relief from the pain that is considered meaningful to the participant.
  • Percentage of Participants Achieving Meaningful Pain Relief [ Time Frame: 15, 30, 45, 60, 90, and 120 minutes and every 60 minutes up to 360 minutes ]
    Participants evaluated the time to first perceptible pain relief by depressing a stopwatch at the moment they first began to experience perceptible relief and the time to meaningful relief by depressing a second stopwatch at the moment they first began to experience meaningful relief defined as relief from the pain that is considered meaningful to the participant.
  • Participant Global Evaluation of Study Medication at 12 Hours [ Time Frame: 12 hours ]
    Participant rated global evaluation of study medication; results reported by evaluation categories and included very poor (0), poor (1), fair (2), good (3), very good (4), and excellent (5).
  • Participant Global Evaluation of Study Medication at 24 Hours [ Time Frame: 24 hours ]
    Participant rated global evaluation of study medication; results reported by evaluation categories and included very poor (0), poor (1), fair (2), good (3), very good (4), and excellent (5).

    PID based on 4-point categorical pain intensity rating scale. Participants asked, "How much pain do you have at this time?" Range of scale: None (0), Mild (1), Moderate (2), Severe (3). PID score derived by subtracting postdose score from baseline score and could range from -1 to 3. A baseline pain intensity score of at least 2 was required for study enrollment. Higher positive PID values indicated greater improvement (decrease in pain intensity).
  • Pain Relief (PR) Score [ Time Frame: 15, 30, 45, 60, 90 minutes and 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 16, and 24 hours ]
    PR score based on 5-point categorical pain relief scale. Participants asked, "How much relief do you have from your starting pain?" Range of scale: None [0], A Little [1], Some [2], A Lot [3] or Complete [4]. Higher scores indicated improvement (better pain relief).
  • Pain Relief Combined With Pain Intensity Difference (PRID) Score [ Time Frame: 15, 30, 45, 60, 90 minutes and 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 16, and 24 hours ]

Baseline pain intensity score of at least 2 was required for study enrollment. Higher positive PID values indicated improvement. PR: 5-point categorical pain relief scale (None [0], A Little [1], Some [2], A Lot [3], Complete [4]). PRID score could range from -1 to 7 where higher scores indicated better pain relief and decrease in pain intensity.
  • Peak Pain Relief Score [ Time Frame: Baseline to 12 hours ]
    Maximum PR score over the scheduled pain relief assessments. PR score based on 5-point categorical pain relief scale. Participants asked, "How much relief do you have from your starting pain?" Range of scale: None (0), A Little (1), Some (2), A Lot (3) or Complete (4). Higher scores indicated improvement (better pain relief).

Descriptive Information
Brief Title  ICMJE Study Evaluating Ibuprofen 600 mg Extended Release (ER) For Dental Pain
Official Title  ICMJE Ibuprofen 600 Mg Extended Release (er) Single-dose Dental Pain Study
Brief Summary The purpose of this study is to assess the efficacy and safety of a single dose of an ibuprofen 600 mg extended release formulation in post-operative dental pain. There is concern that the manufacturing process may affect the performance characteristics of the selected prototype. Therefore, two formulations of this prototype manufactured by two different processes, [roller compaction] and [wet granulation] will be included in this study. The preferred prototype manufactured by two different methods will be compared to placebo and each other. This study will also characterize the pharmacokinetic/pharmacodynamic relationship with these formulations.
