    Percentage of participants with at least one symptomatic hypoglycemic adverse event, excluding data after initiation of glycemic rescue therapy.


Secondary Outcome Measures:
  • Change From Baseline in Fasting Plasma Glucose (FPG) at Week 54 [ Time Frame: Baseline to Week 54 ]
  • Change From Baseline in Body Weight at Week 54 [ Time Frame: Baseline to Week 54 ]
