It is well-known that women with previous gestational diabetes mellitus are in risk of developing type 2 diabetes later in life; approximately half of the women develop overt type 2 diabetes within the first 10 years after pregnancy. Knowing this, we want to examine the effect of the type 2 diabetes medicine, liraglutide (Victoza), in women with previous gestational diabetes with the aim of reducing the risk of developing type 2 diabetes.

Condition Intervention Phase
Gestational Diabetes Mellitus
Drug: Liraglutide
Drug: Placebo
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator)
Primary Purpose: Prevention
Official Title: The Impact of Liraglutide on Glucose Tolerance and the Risk of Type 2 Diabetes in Women With Previous Gestational Diabetes Mellitus

Primary Outcome Measures:
  • Change in glucose tolerance [ Time Frame: from baseline to 52 wks, 53 wks, 260 wks, and 261 wks ]
    Changes in glucose is measured by area under the curve for the plasma glucose excursion following a 4-hour 75 g oral glucose tolerance test (OGTT)

Secondary Outcome Measures:
  • Deterioration in glycaemic status [ Time Frame: from baseline to 52 wks, 53, wks, 260 wks, and 261 wks ]
    Percentage of subjects in each treatment arm with normal glucose tolerance (NGT) at inclusion who develop impaired fasting glucose (IFG) and/or impaired glucose tolerance (IGT) or type 2 diabetes; or with IFG or IGT who develop combined IFG/IGT; or with combined IFG/IGT who develop type 2 diabetes

Other Outcome Measures:
  • Changes in glycated hemoglobin [ Time Frame: From baseline to 52 wks and 260 wks ]
    Changes in glycated hemoglobin (HbA1c). From normoglycaemic to prediabetic or type 2 diabetic and from prediabetic to type 2 diabetic

  • Changes in anthropometric measurements [ Time Frame: from baseline to 52 and 260 wks ]
    Changes in body mass index (BMI)(kg/m2), absolute body weight (kg), and waist:hip ratio

  • Changes in beta cell secretory responses [ Time Frame: from baseline to 52, 53, 260, and 261 wks ]
    changes in area under the curve during OGTT and isoglycemic intravenous glucose infusion (IIGI), the homeostatic model assessment (HOMA) and pro-insulin ratio

  • Changes in insulin sensitivity [ Time Frame: from baseline to 52, 53, 260, and 261 wks ]
    assessed by HOMA-IR and Matsuda insulin sensitivty index

  • Changes in incretin hormone secretion [ Time Frame: baseline to 52, 53, 260, and 261 wks ]
    measured as fasting plasma concentrations and plasma responses of GLP-1, GLP2, and GIP and plasma glucagon during OGTT

  • Changes in incretin effect [ Time Frame: baseline to 52, 53, 260, and 261 wks ]
    insulin and c-peptide responses after OGTT vs. IIGI

  • Changes in cardio-metabolic risk measures [ Time Frame: baseline to 52 and 260 wks ]
  • Changes in subjective appetite [ Time Frame: baseline to 52, 53, 260, and 261 wks ]
  • Quality of life [ Time Frame: baseline to 52 and 260 wks ]
