Brief Summary:
The main objective of this study is to demonstrate the efficacy and safety of multiple-dose application of three different oral doses of CG5503 IR (tapentadol immediate release) compared to placebo in women undergoing abdominal hysterectomy.

Condition or disease Intervention/treatment Phase
Hysterectomy Postoperative Drug: Morphine Drug: CG5503 IR Drug: Placebo Phase 3

Detailed Description:
Subjects undergoing abdominal hysterectomy often experience moderate to severe acute pain post-surgery. Normally such pain is controlled when subjects receive repeated doses of opioid analgesics. However, opioid therapy is commonly associated with side effects such as nausea, vomiting, sedation, constipation, addiction, tolerance, and respiratory depression. Tapentadol (CG5503), a newly synthesized drug with an immediate release (IR) formulation, also acts as a centrally acting pain reliever but has a dual mode of action. The aim of this study is to investigate the effectiveness (level of pain control) and safety (side effects) of 3 dose levels of CG5503 IR compared with no drug (placebo) or one dose level of morphine (an opioid commonly used to treat post-surgical pain). This study is a randomized, double-blind (neither investigator nor patient will know which treatment was received), active- and placebo-controlled, parallel-group, multicenter study to evaluate the treatment of acute pain after abdominal hysterectomy. The study will include a blinded 72 hour in-patient phase immediately following hysterectomy, during which subjects will be treated with either 50-, 75-, or 100-mg CG5503 IR, a matched placebo, or 20-mg morphine, and pain relief will be periodically assessed. Assessments of pain relief include the pain intensity numeric rating scale (PI), pain relief numeric rating scale (PAR), and patient global impression of change scale (PGIC). Safety evaluations include monitoring of adverse events, physical examinations, and clinical laboratory tests. Venous blood samples will be collected for the determination of serum concentrations of CG5503 and morphine. The alternative study hypothesis is that at least 1 dose strength of CG5503 will be different from placebo in controlling pain at 24 hours (using the mean SPID at 24 hours).

Primary Outcome Measures :
  1. Sum of Pain Intensity Differences Relative to the Baseline Pain Intensity. [ Time Frame: Baseline to 24 hours after first intake of study drug ]
    Pain Intensity assessed at predefined time points over a 24 hour period using an 11-point Numeric Rating Scale (NRS) where a score of zero indicates "no pain" and a score of ten indicates "pain as bad as you can imagine". Differences calculated as [baseline-post baseline] at each predefined time point. The theoretical maximum range of Sum of pain intensity differences (SPID24) is from -240 (indicative of an increase in pain) to 240 (indicative of a decrease in pain, assuming patients start with a baseline value of 10 and all subsequent values will be 0).


Secondary Outcome Measures :
  1. Sum of Pain Intensity Differences Relative to the Baseline Pain Intensity [ Time Frame: Baseline value to 48 hours after first study drug intake. ]
    Pain Intensity assessed at predefined time points over a 48 hour period using an 11-point Numeric Rating Scale (NRS) where a score of zero indicates "no pain" and a score of ten indicates "pain as bad as you can imagine". Differences calculated as [baseline-post baseline] at each predefined time point. The theoretical maximum range of Sum of pain intensity differences (SPID48) is from -480 (indicative of an increase in pain) to 480 (indicative of a decrease in pain, assuming patients start with a baseline value of 10 and all subsequent values will be 0).
