Have a history of myocardial infarction or coronary artery bypass graft surgery within the preceding 12 months. Have a history or clinical manifestations of significant renal, hepatic, cardiovascular, metabolic, neurologic, psychiatric, or other condition that would preclude participation in the study. Have a history of migraine or frequent headaches, seizures, or are currently taking anticonvulsants. Have another painful physical condition that may confound the assessments of post operative pain. Have a history of advanced malignant tumor. Have a history of alcohol abuse (regularly drinks \> 4 units of alcohol per day; 8 oz. beer, 3 oz. wine, 1 oz. spirits) within the past 5 years or a history of prescription/illicit drug abuse. Have positive results on the urine drug screen or alcohol breath test indicative of illicit drug or alcohol abuse. Have evidence of a clinically significant 12 lead ECG abnormality.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Summed Pain Intensity Difference Over the First 24 Hours (SPID24) | 24 Hours | Pain intensity was recorded using a Numeric Pain Rating Scale (Range 0-10) where 0 equates to no pain (better), and 10 equates to the worst pain imaginable (worse). Pain intensity scores were to be recorded at the following time points: 0.25, 0.5, 0.75, 1, and 2 hours post Dose 1. Thereafter pain assessments were to be recorded every 2 hours until 48 hours post Dose 1. Pain intensity differences from baseline at each time point were calculated and a time weighted summed pain intensity difference (SPID) was then calculated. Time weighted SPID calculations were computed by multiplying a weight factor to each score prior to summation. The weight factor at each time point was the time elapsed since the previous observation. A smaller SPID value (i.e. more negative) was better. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Summed Pain Intensity Difference (SPID) at Other Intervals | 48 Hours | Pain intensity was recorded using a Numeric Pain Rating Scale (Range 0-10) where 0 equates to no pain (better), and 10 equates to the worst pain imaginable (worse). Pain intensity scores were to be recorded at the following time points: 0.25, 0.5, 0.75, 1, and 2 hours post Dose 1. Thereafter pain assessments were to be recorded every 2 hours until 48 hours post Dose 1. Pain intensity differences from baseline at each time point were calculated and a time weighted summed pain intensity difference (SPID) was then calculated. Time weighted SPID calculations were computed by multiplying a weight factor to each score prior to summation. The weight factor at each time point was the time elapsed since the previous observation. A smaller SPID value (i.e. more negative) was better. |
| Time to First Dose of Rescue Analgesia | 48 Hours | Rescue analgesia (oral oxycodone 5 mg) was available to subjects with inadequately controlled pain upon request. Time to first rescue was calculated as the elapsed time from administration of Dose 1 to the administration of the first dose of rescue analgesia. |
| Number of Subjects Utilizing Rescue Analgesia | 48 Hours | Rescue analgesia (oral oxycodone 5 mg) was available to subjects with inadequately controlled pain upon request. |
