Primary Outcome Measures:
  • Change From Baseline in 24-hour Weighted Mean Plasma Glucose [ Time Frame: Baseline and Week 4 ] [ Designated as safety issue: No ]
    Change from baseline at Week 4 is defined as 24-hour weighted mean glucose (24hr-WMG) at Week 4 minus 24hr-WMG at Week 0.

Secondary Outcome Measures:
  • Change From Baseline in Plasma Glucose [ Time Frame: Baseline and Week 4 ] [ Designated as safety issue: No ]
    Change from baseline at Week 4 is defined as fasting plasma glucose at Week 4 minus fasting plasma glucose at Week 0.
