A Randomized, Double-Blind, Parallel-Arm, Placebo and Active Controlled Dose-Ranging Study of the Efficacy and Safety of Multiple Doses of Tapentadol IR for Postoperative Pain Following Bunionectomy Surgery
This study was to evaluate the efficacy and safety of dosing regimens of tapentadol HCl immediate release capsules for the treatment of postoperative pain over a period of 12 hours on the first day following a bunionectomy in men and women.

|Official Title:||A Randomized, Double-Blind, Parallel-Arm, Placebo and Active Controlled Dose-Ranging Study of the Efficacy and Safety of Multiple Doses of CG5503 (Tapentadol) IR for Postoperative Pain Following Bunionectomy Surgery|
- Primary objective was that at least 1 of the treatment regimens with tapentadol IR was superior to placebo as measured by the sum of total pain relief and sum of pain intensity difference over 12 hours (SPRID12) on the first day after a bunionectomy.
- Secondary objectives included evaluation of several additional pain measures, tolerability to treatments, and drug pharmacokinetics and pharmacodynamics.

Tapentadol hydrochloride is a centrally active analgesic (antinociceptive) compound. This was a multicenter, randomized, double-blind, parallel-group, placebo- and active-controlled dose study in men and nonpregnant, nonlactating women. The patients were at least 18 and no more than 75 years of age and experienced moderate to severe pain within 9 hours after removal of postoperative analgesia. The surgery was a standardized first metatarsal bunionectomy. Treatment of postsurgical pain after the 9 hr period was with either placebo, tapentadol, or oxycodone using various dosing regimens. The primary objective of this study was to evaluate the efficacy and safety of these treatments on total pain relief and total change in pain intensity over 12 hours and reporting of adverse events, laboratory values, vital signs, and ECGs. Secondary objectives included evaluation of several other pain measures, and drug pharmacokinetics and pharmacodynamics. Six patient treatment groups received study medication orally at 0, 4, and 8 hours with one of the following dosing regimens: 1) placebo, placebo, and placebo, 2) 93 mg, 93 mg, and 93 mg tapentadol IR, 3) 140 mg, 140 mg, and 140 mg tapentadol IR, 4) 140 mg, 70 mg, and 70 mg tapentadol IR, 5) 186 mg, 93 mg, and 93 mg tapentadol IR, and 6) 10 mg, 10 mg, and 10 mg oxycodone IR.
