Study Summary

The purpose of this study is to test in patients who have had hip replacement surgery the effectiveness (level of pain control) and the safety of 3 different dose levels of CG5503 compared with placebo and with 10-mg oxycodone during the 72-hour double-blind period and to assess the safety of the drug for 9 days after patients completed the double blind period.

Primary Outcome

The SPID score incorporates the cumulative analgesic effects of tapentadol IR on pain intensity over an extended period (48 hours) allowing for an evaluation of multiple doses of drug, even when dosing frequency may vary. Scoring is derived from the Numerical Rating Scale (NRS) from 0 = No pain to 11 = Pain as bad as you can imagine.
