About this study

Official title: A Randomized, Double-Blind, 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; Bridging Study for Korea

The purpose of this study is to demonstrate the efficacy of at least 1 dose of tapentadol IR 50 mg and/or 75 mg versus placebo using the sum of pain intensity difference at 48 hours (SPID48) to measure analgesic effect in Korean patients with acute pain following bunionectomy.

Read the detailed description

This is a randomized (study drug assigned by chance like flipping a coin), double-blind (neither physician nor patient knows the name of the assigned drug), placebo-controlled, parallel-group, multicenter study to evaluate the efficacy and safety of tapentadol immediate-release (IR) 50 mg and 75 mg in patients who are undergoing bunionectomy (a surgical procedure to remove a bunion). This study was designed to be a similar study to the pivotal global study of PAI-3003/KF32 in order to bridge the results from the global studies and to show similarity in effect of tapentadol between Korean and Caucasian population which will allow extrapolation of the foreign clinical data of tapentadol into Korea. The study will be divided into screening period, surgical period, qualification period, and a double-blind treatment period. The study length, including the screening period, will be up to a maximum duration of 32 days. Eligible patients will be randomly assigned to 1 of 3 treatment groups (tapentadol IR 50 mg, tapentadol IR 75 mg or placebo) in a 1:1:1 ratio. Efficacy and safety assessments will be performed during the study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sum of Pain Intensity Differences (SPID) Over 48 Hours

    Pain Intensity (PI) was assessed on an 11-point numerical rating scale from 0=no pain to 10=pain as bad as you can imagine. PID was the difference between baseline PI (prior to the first dose) and current PI at assessment. SPID was calculated as the time-weighted Sum of PID scores over 48 hours. Total score ranges from -480 (worst) to 480 (best) for SPID48. A higher value of SPID indicates greater pain relief.

    Measured: 48 hours

Secondary outcomes (8)
  1. Time to First Rescue Medication Use

    Rescue medication was defined as any analgesic medication used for participants discontinued due to lack of efficacy (including those started at time of discontinuation) or analgesic medication used during the double-blind period for completed participants.

    Measured: Up to 48 hours

  2. Percent Reduction in Pain Intensity From Baseline at 12, 24, 48, and 72 Hours

    Pain intensity was assessed on a 11-point numerical rating scale from 0=no pain to 10=pain as bad as you can imagine. Participants with no assessment at the given time point, who used an analgesic medication prior to the time point, or who had worse pain intensity at the time point compared to baseline were assigned a percent reduction of 0 percent.

    Measured: Baseline (Day 1) and 12, 24, 48, and 72 hours

  3. Response Rate for 30 Percent or Greater Reduction in Pain Intensity at 12, 24, 48, and 72 Hours

    Response rate was defined as the percentage of participants with a 30 percent or greater reduction in pain intensity from baseline to 12, 24, 48, and 72 hours. Pain intensity was assessed on a 11-point numerical rating scale from 0=no pain to 10=pain as bad as you can imagine. Participants with no assessment at the given time point, who used an analgesic medication prior to the time point, or who had worse pain intensity at the time point compared to baseline were assigned a percent reduction of 0 percent.

    Measured: 12, 24, 48, and 72 hours

  4. Response Rate for 50 Percent or Greater Reduction in Pain Intensity at 12, 24, 48, and 72 Hours

    Response rate was defined as the percentage of participants with a 50 percent or greater reduction in pain intensity from baseline to 12, 24, 48, and 72 hours. Pain intensity was assessed on a 11-point numerical rating scale from 0=no pain to 10=pain as bad as you can imagine. Participants with no assessment at the given time point, who used an analgesic medication prior to the time point, or who had worse pain intensity at the time point compared to baseline were assigned a percent reduction of 0 percent.

    Measured: 12, 24, 48, and 72 hours

  5. Sum of Pain Intensity Differences (SPID) Over 12, 24, and 72 Hours

    Pain Intensity (PI) was assessed on an 11-point numerical rating scale from 0=no pain to 10=pain as bad as you can imagine. PID was the difference between baseline PI (prior to the first dose) and current PI at assessment. SPID was calculated as the time-weighted Sum of PID scores over 12, 24, and 72 hours. Total score ranges from -120 (worst) to 120 (best) for SPID12, -240 (worst) to 240 (best) for SPID24, -720 (worst) to 720 (best) for SPID72. A higher value of SPID indicates greater pain relief.

    Measured: 12, 24, and 72 hours

  6. Total Pain Relief (TOTPAR) Over 12, 24, 48, and 72 Hours

    Participants rated pain relief rated on 5-point categorical scale of 0-4 (0=none, 1=A little, 2=Some, 3=A lot, 4=Complete). Total Pain Relief (TOTPAR) was calculated as the time-weighted sum of pain relief scores up to Hour 12, 24, 48, and 72 hours. Total score ranges from 0 (worst) to 48 (best) for TOTPAR12, 0 (worst) to 96 (best) for TOTPAR24, 0 (worst) to 192 (best) for TOTPAR48, and 0 (worst) to 288 (best) for TOTPAR72. A higher value of TOTPAR indicated greater pain relief.

    Measured: 12, 24, 48, and 72 hours

  7. Sum of Pain Relief and Pain Intensity Differences (SPRID) Over 12, 24, 48, and 72 Hours

    Participants rated pain relief rated on 5-point categorical scale of 0-4 (0=none, 1=A little, 2=Some, 3=A lot, 4=Complete). Pain Intensity (PI) was assessed on an 11-point numerical rating scale from 0=no pain to 10=pain as bad as you can imagine. PID was the difference between baseline PI (prior to the first dose) and current PI at assessment. PRID is the sum of pain relief and PID at the same assessment time. SPRID was calculated as the time-weighted Sum of PRID scores over 12, 24, 48, and 72 hours. Total score ranges from -120 (worst) to 168 (best) for SPRID12, -240 (worst) to 336 (best) for SPRID24, -480 (worst) to 672 (best) for SPRID48, and -720 (worst) to 1008 (best) for SPRID72. A higher value of SPRID indicates greater pain relief.

    Measured: 12, 24, 48, and 72 hours

  8. Patient Global Impression of Change (PGI-C) Score at 72 Hours

    The PGI-C is a 7-point scale that requires the patients to assess how much their illness has improved or worsened relative to a baseline state at the beginning of the intervention. The response options are: 1=very much improved; 2=much improved; 3=minimally improved; 4=no change; 5=minimally worse; 6=much worse; and 7=very much worse. Higher scores indicate worsening.

    Measured: Baseline (Day 1) and 72 hours
