Primary Outcome Measures:
  • Change from baseline in HbA1c at six months [ Time Frame: baseline and six months ] [ Designated as safety issue: No ]
    Glycemic control as measured by HbA1c


Secondary Outcome Measures:
  • Hypoglycemia [ Time Frame: 6 months and 12 months ] [ Designated as safety issue: Yes ]
    The frequency and severity of hypoglycemia in each treatment arm by glucose meter download and by percent time spent in the hypoglycemic range (BG < 70 mg/dl) by CGM will be assessed at six and 12 months

  • Total Daily Insulin Dose (TDID) [ Time Frame: 3, 6, 9, and 12 months ] [ Designated as safety issue: No ]
    TDID will be determined in each treatment arm for statistical comparisons at three and six months, and for entire cohort at nine and 12 months.

  • Weight [ Time Frame: baseline, 3, 6, 9, and 12 months ] [ Designated as safety issue: No ]
    Weight will be statistically compared to baseline and between treatment arms at three and six months, and for entire cohort between baseline, six, nine and 12 months.

  • GlycoMark [ Time Frame: baseline, 3, 6, 9, and 12 months ] [ Designated as safety issue: No ]
    Postprandial glycemic control as assessed by GlycoMark and CGM will be compared between study groups at three and six months, and for entire cohort compared to baseline at nine and 12 months.

Other Names:
  • U-500
  • Levemir
  • Novolog

Detailed Description:

40 subjects with Type 2 diabetes using > 100 units of insulin per day with or without metformin with HbA1c > 6.5% will be randomized into 2 treatment groups: treatment group will have liraglutide added to insulin and control group will have insulin uptitration only for 6 months. Primary endpoint to be compared between groups will be HbA1c at 6 months. Secondary endpoints will include weight, total daily insulin dose, percent time in euglycemic, hyperglycemic, and hypoglycemic ranges by continuous glucose monitor (CGM), and effect on GlycoMark and hs-CRP. Safety endpoints will include incidence of hypoglycemia and incidence of gastrointestinal side effects.
