A Study to Evaluate the Effectiveness and Safety of Tapentadol (CG5503) in the Treatment of Acute Pain From Bunionectomy.

April 24, 2014 updated by: Johnson & Johnson Pharmaceutical Research & Development, L.L.C.

A Randomized, Double-Blind, Active- and Placebo-Controlled, Parallel-Group, Multicenter Study to Evaluate the Efficacy and Safety of Tapentadol Immediate-Release Formulation in the Treatment of Acute Pain From Bunionectomy

The purpose of this study is to evaluate the effectiveness (level of pain control) and safety of the administration of 2 different dose levels of tapentadol (CG5503) compared with oxycodone and with placebo in subjects who have had a bunionectomy.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients undergoing bunionectomy often experience moderate to severe acute pain post-surgery. Normally such pain is controlled when patients receive repeated doses of opioid analgesics. However, opioid therapy is commonly associated with side effects such as nausea, vomiting, sedation, constipation, and less frequently, respiratory depression. Tapentadol (CG5503), a newly synthesized drug with an immediate release (IR) formulation, also acts as a centrally acting analgesic 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 2 dose levels of tapentadol (CG5503) IR compared to no drug (placebo) or one dose level of oxycodone (an opioid commonly used to treat post-surgical pain). This study is a randomized, double-blind (neither investigator nor patient will know which treatment is received), active- and placebo-controlled, parallel-group, multicenter study to evaluate treatment of the acute pain from bunionectomy. The study will include a blinded 72 hour inpatient (the patient will stay in the facility where the procedure is done) phase immediately following bunionectomy, during which patients will be treated with either 50- or 75-mg tapentadol (CG5503) IR, a placebo, or 10-mg oxycodone IR, and pain relief will be periodically assessed. Assessments of pain intensity (PI) and pain relief (PAR) are obtained using the numerical rating scale, and the patient global impression of change scale (PGIC) will measure overall patient status. 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 tapentadol (CG5503) and oxycodone. The study hypotheses are that at least one tapentadol (CG5503) IR dose will be different from placebo in controlling patients pain at 48 hours, followed by establishing that at least one tapentadol (CG5503) IR dose will be non-inferior compared with oxycodone IR (oxycodone IR is not clinically significantly better than a tapentadol (CG5503) IR dose). A comparison of the incidence rate of the adverse events of nausea and/or vomiting, and the incidence rate of the adverse event of constipation, between tapentadol (CG5503) IR and oxycodone IR will also be performed. Tapentadol (CG5503) IR 50 or 75 mg, or oxycodone 10 mg, or placebo, 1 capsule taken by mouth every 4 to 6 hours during the 72-hour postsurgery phase of the study (acetaminophen is also allowed during the first 12 hours on Day 1, if needed for pain). All doses of study treatment will be taken with approximately 120 mL of water with or without food.

Phase

Phase

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Sum of Pain Intensity Difference Over 48 Hours (SPID48)
Time Frame: 48 hours
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. A positive difference between the mean SPID48 for an active study drug and placebo would indicate a numerically larger analgesic effect for subjects dosed with active study drug than in the placebo group. A higher value in SPID indicates greater pain relief.
48 hours

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Time to First Rescue Pain Medication Use.
Time Frame: 3 days
The effect of tapentadol (CG5503) IR on the time to the first use of rescue pain medication.
3 days
The SPID at 12 Hours Relative to First Dose.
Time Frame: 12 hours
The SPID score incorporates the cumulative analgesic effects of tapentadol IR on pain intensity over an extended period (12 to 72 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. A positive difference between the mean SPID12 for an active study drug and placebo would indicate a numerically larger analgesic effect for subjects dosed with active study drug than in the placebo group. A higher value in SPID indicates greater pain relief.
12 hours
SPID at 24 Hours Relative to First Dose
Time Frame: 24 hours
The SPID score incorporates the cumulative analgesic effects of tapentadol IR on pain intensity over an extended period (12 to 72 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. A positive difference between the mean SPID24 for an active study drug and placebo would indicate a numerically larger analgesic effect for subjects dosed with active study drug than in the placebo group. A higher value in SPID indicates greater pain relief.
24 hours
Percentage of Patients Who Reported Very Much Improved or Much Improved From Baseline in Patient Global Impression of Change to Day 3
Time Frame: Baseline and 3 days
Ordinal measure indicating change from the start of treatment (On a scale of 7 = Very much Worse to 1 = very much improved) to endpoint at Day 3
Baseline and 3 days
Total Pain Relief (TOTPAR)at 48 Hours
Time Frame: 48 hours
Total Pain Relief (TOTPAR48) was defined as the weighted sum over all pain relief scores(PAR) from 0.5 hour to Hour 48, with the actual time elapsed from the previous PAR observation as the weight. A higher value in TOTPAR indicates greater pain relief.
