  • Change From Baseline in CV Biomarkers Adiponectin and Apolipoprotein B (ApoB) at Week 26 [ Time Frame: Baseline, Week 26 ] [ Designated as safety issue: No ]
  • Change From Baseline in 24-Hour Continuous Glucose Monitoring System (CGMS) Glucose Values at Week 26 [ Time Frame: Baseline, Week 26 ] [ Designated as safety issue: No ]
  • Change From Baseline in Mean Standard Deviation (SD) of 24-Hour Glucose Values Measured by CGMS at Week 26 [ Time Frame: Baseline, Week 26 ] [ Designated as safety issue: No ]
  • Number of Subjects With Hypoglycemic Events [ Time Frame: Months 1 to 7 ] [ Designated as safety issue: Yes ]
  • Number of Total Hypoglycemic Events [ Time Frame: Months 1 to 7 ] [ Designated as safety issue: Yes ]
