Primary Outcome Measures:
  • 24-hour Weighted Mean Glucose (WMG) [ Time Frame: Day 7 of Treatment Period I. Due to a carry-over effect that was observed between treatment periods, efficacy results are presented from Treatment Period I only. ]
    The 24-hour WMG was calculated as the area under the 24-hour glucose curve (AUC(0-24 hr)) divided by 24 using linear trapezoidal method.
