Adding Liraglutide to High Dose Insulin: Breaking the Cycle

15 de dezembro de 2017 atualizado por: Ildiko Lingvay

The purpose of this study is to evaluate whether the addition of liraglutide 1.8 mg/day to a high-dose insulin regimen (>1.8 units/kg/day) in patients with uncontrolled (HbA1c >7.5%) type 2 diabetes mellitus will improve blood sugar control.

It also evaluates the effect of liraglutide on liver and pancreatic fat content, explores the mechanism of blood sugar improvement by assessing weight and pancreatic hormone release, and assesses blood pressure, lipid profile, and liver function. Finally it will look at patient quality of life and safety.

Descrição detalhada

Type 2 diabetes is a progressive disease with incessant beta-cell dysfunction that often ultimately requires insulin treatment. Patients requiring high insulin dosages represent a particular treatment challenge and often have uncontrolled glycemia despite progressive dose increases and are especially prone to insulin related lipotoxicity and weight gain.

Glucagon-like peptide agonists (GLP-1) such as liraglutide have many actions that position them to break the vicious cycle in this population through the following mechanisms: (1) weight loss; (2) improved hepatic steatosis; (3) improved pancreatic steatosis; (4) decreased glucagon levels; (5) improved beta-cell function.

The purpose of the study is to demonstrate that liraglutide is both effective and safe when added to a high dose insulin treatment regimen. Liraglutide will improve glycemic control, weight, metabolic parameters, as well as patient satisfaction, with minimal adverse events. The study also proposes to study the mechanisms through which such improvements might occur, especially beta-cell function, glucagon levels, and hepatic and pancreatic fat content.

Descrição

Inclusion Criteria:

  • Type 2 diabetes mellitus
  • Insulin dose of >1.8 units/kg/day (represents total daily insulin dose, regardless of formulation, regimen, number of daily shots)
  • HbA1c ≥ 7.5% and ≤ 11%
  • Age ≥ 18
  • Stable comorbidities on stable treatment regimens
  • Stable dose of all oral hypoglycemics for ≥ 3 months prior to enrollment
  • Ability to provide informed consent before any trial-related activities

Exclusion Criteria:

  • Type 1 diabetes mellitus
  • Any contraindication to the MRI procedure (metallic implants, severe claustrophobia, pregnancy, unable to lie still on a hard table for the duration of the procedure, weight above 400 lb - limit of the MRI table, magnet's inner circumference smaller than the largest body circumference)
  • History of any pancreatic disease as it might interfere with the pancreatic TG measurement (i.e. pancreatitis, tumors, cysts, type 1 diabetes, any pancreatic surgery)
  • End Stage Renal Disease on dialysis due to increased risk of hypoglycemia, and possible interference with accurate measurement of HbA1c
  • Incretin therapy (any GLP-1 agonist or DPP-IV inhibitor)
