Detailed Description

This randomized, open label, four-way crossover phase I study is to evaluate the food effect of Ibuprofen CR Tablets 600 mg (IBUCR), and its bioavailability comparison versus 3 doses of the reference arms including Advil® Ibuprofen Tablets 200 mg (IBUAdv) and Motrin® IB Ibuprofen Tablets 200 mg (IBUMot) in normal healthy volunteers. This study will enroll at least 26 evaluable subjects. The duration for test and reference treatments is 24 to 32 hours with a washout period of at least 5 days after the last dose administration of study drugs.

Clinical Trial Outcome Measures

Primary Measures

  • Area under the curve from time zero to the time of the last quantifiable plasma concentration of the period (AUC0-last)
    • Time Frame: 1 month
    • The 90% CI for the geometric mean ratios (i.e., antilog-transformation for 90% CI of difference with log transformation) of AUC0-last within [0.8, 1.25] range will be used to determine the result of bioequivalence.
  • Area under the curve from time zero to infinity (AUC0-inf)
    • Time Frame: 1 month
    • The 90% CI for the geometric mean ratios (i.e., antilog-transformation for 90% CI of difference with log transformation) of AUC0-inf within [0.8, 1.25] range will be used to determine the result of bioequivalence.
  • Peak concentration at each treatment period (Cmax,tp)
    • Time Frame: 1 month
    • The 90% CI for the geometric mean ratios (i.e., antilog-transformation for 90% CI of difference with log transformation) of Cmax,tp within [0.8, 1.25] range will be used to determine the result of bioequivalence.

Secondary Measures

  • Peak concentration of the first dosing (Cmax)
    • Time Frame: 1 month
    • Individual ibuprofen plasma concentration-time profile for each treatment period will be established.
  • Time to reach peak concentration of the first dosing (Tmax)
    • Time Frame: 1 month
