Efficacy And Safety Of Parecoxib 40mg vs. Ketoprofen 100mg In The Management Of Acute Renal Colic

This is a multicenter, randomized, double blind, double dummy, comparative, active-controlled trial designed to assess the analgesic activity and safety of intravenous doses of parecoxib 40 mg relative to intravenous doses of ketoprofen 100 mg for the treatment of renal colic in outpatients presenting at emergency room settings. This trial is designed to show non-inferiority of parecoxib related to ketoprofen.

Inclusion criteria

  • Patient male or female with a confirmed diagnosis of acute renal colic with moderate to severe pain according to the VAS and Categoric pain scales

Exclusion criteria

  • The patient has significant renal or hepatic conditions other than uncomplicated kidney stones.
  • The patient has a history of clinically significant hypersensitivity to any NSAIDs, cyclooxygenase inhibitors, analgesics or sulfa medications which has a cross sensitivity to the medications used in this study.

Treatment and study plan

Ketoprofen 100mg

Drug

Ketoprofen 100 mg diluted in 100 ml of normal sodium chloride solution into the established patient's IV line by slow injection in a 20-minute period; and IV dose of 2 ml of normal sodium chloride solution as placebo for Parecoxib by bolus injection

Parecoxib 40mg

Drug

Parecoxib 40 mg diluted in 2 ml of normal sodium chloride solution administered by bolus injection; and an IV dose of 100 ml of normal sodium chloride solution as placebo for ketoprofen administered in a in a 20-minute period

Primary outcomes

  1. Mean Pain Intensity Difference at 30 Minutes (mPID30min)

    Time frame: Minute 30

    mPID score was obtained by summation of product of length of the interval and difference in pain intensity (PI) divided by summation of length of the interval. Summation was done from zero to 30 minutes. Difference in pain intensity was obtained by subtracting the Pain Intensity Visual Analogue Scale (PI-VAS) at Minute 30 from baseline PI-VAS score. PI-VAS assessed with response to the question "How much pain are you having right now?" on a 100 millimeter (mm) line, with 0 mm=no pain, 100 mm= worst possible pain. mPID score ranged from -100 to 100. Positive score= improved response in pain.

Secondary outcomes

  1. Mean Pain Intensity Difference at 120 Min (mPID120min)

    Time frame: Minute 120

    mPID score was obtained by summation of product of length of the interval and difference in pain intensity (PI) divided by summation of length of the interval. Summation was done from zero to 120 minutes. Difference in pain intensity was obtained by subtracting the Pain Intensity Visual Analogue Scale (PI-VAS) at Minute 120 from baseline PI-VAS score. PI-VAS assessed with response to the question "How much pain are you having right now?" on a 100 millimeter (mm) line, with 0 mm=no pain, 100 mm= worst possible pain. mPID score ranged from -100 to 100. Positive score= improved response in pain.

  2. Time-specific Pain Intensity (PI) VAS Score

    Time frame: Baseline, Minute 15, 30, 45, 60, 90, 120

    PI-VAS assessed with response to the question "How much pain are you having right now?" on a 100 mm line, with 0 mm=no pain, 100 mm= worst possible pain.

  3. Time-specific Pain Intensity Difference (PID) at Minute 15, 30, 45, 60, 90 and 120

    Time frame: Baseline, Minute 15, 30, 45, 60, 90, 120

    PID score was obtained by subtracting the PI-VAS at each time point from baseline PI score. PI-VAS assessed with response to the question "How much pain are you having right now?" on a 100 mm line, with 0 mm=no pain, 100 mm= worst possible pain. PID score ranged from -100 to 100. Positive score= improved response in pain.

  4. Time-weighted Sum of Pain Relief Score Over 120 Min (TOTPAR120min)

    Time frame: Baseline through Minute 120

    TOTPAR: time-weighted sum of Pain Relief (PR) over 120 min. TOTPAR score range was 0 (worst) to 480 (best). PR was assessed on a 5-point categorical pain relief rating scale wherein 0=No relief to 4=Complete relief.

  5. Number of Participants With Pain Relief (PR)

    Time frame: Minute 30, 120

    PR was assessed on a 5-point categorical pain relief rating scale wherein 0= None, 1= a little, 2= Some, 3= a lot and 4= Complete relief.

  6. Number of Participants With Response in Pain Intensity

    Time frame: Minute 30

    PI-VAS assessed with response to the question "How much pain are you having right now?" on a 100 mm line, with 0 mm=no pain, 100 mm= worst possible pain. Responders were those who had a decreased in VAS of at least 20 mm.

  7. Patient's Global Evaluation of Study Medication

    Time frame: Minute 30, 120

    Participants' response to the question "How would you rate the study medication you received for pain?" on a 4-point categorical scale, 1=Poor, 2= Fair, 3=Good, 4=Excellent was evaluated.

  8. Physician's Global Evaluation of Study Medication

    Time frame: Minute 30, 120

    Physicians' response to the question "How would you rate the study medication the patient received for pain?" on a 4-point categorical scale, 1=Poor, 2= Fair, 3=Good, 4=Excellent was evaluated.

  9. Number of Participants With Use of Rescue Medication (RM)

    Time frame: Up to Minute 120

    Rescue medications included intravenous 0.1 to 0.2 mg/kilogram (kg) of morphine or 1 mg/kg of pethidine or muscle relaxants.
