  Purpose

The primary purpose of this study is to compare the effect on 24-hour blood glucose patterns, HbA1c, and weight management when adding insulin glargine, or exenatide, or a combination of insulin glargine and exenatide to metformin.

Primary Outcome Measures:
  • Continuous Glucose Monitoring [ Time Frame: 40 weeks ] [ Designated as safety issue: No ]

    Employ CGM with AGP analysis to characterize the diurnal patterns produced by oral medications (metformin) used in the treatment of type 2 diabetes.

    Employ CGM to measure the effect of exenatide, insulin glargine and exenatide plus insulin glargine in terms of underlying physiological defects and alter medications in a manner that improves- i. Glucose exposure (area under the diurnal median curve) ii. Glucose variability (inter-quartile range) iii. Glucose stability (hourly change in the median curve iv. Incidence of hypoglycemia (degree, duration, frequency)



Secondary Outcome Measures:
  • Continuous Glucose Monitoring and Lab Tests [ Time Frame: 40 weeks ] [ Designated as safety issue: No ]

    Measure the changes in HbA1C attributable to exenatide, insulin glargine and their combination Measure the changes in weight attributable to exenatide, insulin glargine and their combinations.

    Employ CGM with AGP analysis to determine if there is an incremental benefit for subjects who do not reach target to add exenatide to insulin glargine or insulin glargine to exenatide in patients taking metformin.
