Design and methods of a randomised double-blind trial of adding liraglutide to control HbA1c in patients with type 2 diabetes with impaired glycaemic control treated with multiple daily insulin injections (MDI-Liraglutide trial)

Published:August 28, 2014DOI:https://doi.org/10.1016/j.pcd.2014.07.010

      Highlights

      • The first study of its kind on incretin-based therapy together with MDI therapy.
      • The majority of the studied patient group can be found in primary care settings.
      • Glycaemic variability will be evaluated by masked continuous glucose monitoring.

      Abstract

      Aims

      Patients with type 2 diabetes are generally treated in primary care setting and as a final treatment step to obtain good glycaemic control, multiple daily insulin injections (MDI) are generally used. The aim of this study is to evaluate the effect of GLP-1 analogue liraglutide on glycaemic control in patients with type 2 diabetes treated with MDI with inadequate glycaemic control.

      Methods

      Overweight and obese patients with type 2 diabetes and impaired glycaemic control treated with MDI were randomised to liraglutide or placebo over 24 weeks. Masked continuous glucose monitoring was performed at baseline and during the trial. The primary endpoint was the change in haemoglobin A1c from baseline to week 24. Additional endpoints include changes in weight, fasting glucose, glycaemic variability, treatment satisfaction, insulin dose, hypoglycaemias, blood pressure and blood lipid levels.

      Results

      Recruitment occurred between February 2013 and February 2014. A total of 124 patients were randomised. Study completion is anticipated in August 2014.

      Conclusions

      It is expected that the results of this study will establish whether adding liraglutide to patients with type 2 diabetes treated with MDI will improve glycaemic control, lower body weight, and influence glycaemic variability.
