简要总结

This is a Phase 3, two-arm, double-blind study of efficacy and safety of Q8003 in patients who have undergone primary unilateral total knee arthroplasty

详细描述

This Phase 3 study is a two-arm, double-blind study to:

  • compare the analgesic efficacy and safety of the flexible regimen of Q8003 (6 mg/4 mg up to 24 mg/16 mg) administered every 4-6 hours over a 48-hour Treatment Period versus low dose Q8003 (every 4-6 hours 3 mg/2 mg with a 6 mg/4 mg loading dose) to inpatients with moderate to severe postoperative pain who have undergone primary unilateral total knee arthroplasty.
  • to evaluate the efficacy and safety of Q8003 when administered in the Voluntary Extension Period starting at 48 hours after the initial dosing and extending up to Day 12.

  • Have undergone a primary unilateral total knee arthroplasty performed under under standardized general, spinal or epidural anesthesia.
  • Have developed moderate to severe pain (a score of 2 or more on the 4 point Likert scale and at least 4 on the 11 point NPRS scale within 6 hours of discontinuing PCA on the morning after surgery).

排除标准

  • In the opinion of the Investigator, has a history of pulmonary, cardiovascular (including uncontrolled hypertension), neurologic, endocrine, hepatic, gastrointestinal, or kidney disease or therapy that, in the opinion of the Investigator, would jeopardize the patient's well being by participation in this study or is mentally or emotionally unsuitable to participate, or unable/unwilling to comply with the study assessments.

  • Was dosed with another investigational drug within 30 days prior to the Screening Visit or has previously received treatment with Q
  • Current therapy with central nervous system depressant medications that might increase the risks of treatment with opioids (other than those used with surgical anesthesia).
  • Current evidence of alcohol abuse (regularly drinks more than 4 units of alcohol per day; 1 unit = ½ pint of beer, 1 glass of wine, or 1 ounce of spirit).
  • History of abusing licit or illicit drug substances within five (5) years of study entry.
