LIraglutide and Beta-cell RepAir (LIBRA) Study

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by progressive deterioration in the function of the pancreatic beta-cells, which are the cells that produce and secrete insulin (the hormone primarily responsible for the handling of glucose in the body). We propose a double-blind, randomized controlled study comparing the effect of liraglutide (a novel anti-diabetic drug with beta-cell protective potential) versus placebo, on the preservation of beta-cell function over one year in patients with T2DM. This study may demonstrate an important beta-cell protective capacity of liraglutide.

About this study

In this study, patients with type 2 diabetes who meet randomization criteria will be randomized to either liraglutide or placebo, with serial assessment of beta-cell function over 48 weeks follow-up. The hypothesis under study is whether liraglutide can preserve beta-cell function.

Primary outcomes

  1. Preservation of beta-cell function measured by Insulin Secretion-Sensitivity Index-2 (ISSI-2)

    Time frame: 48-weeks

    ISSI-2 is a validated OGTT-derived measure of beta-cell function analogous to the disposition index obtained from the intravenous glucose tolerance test. ISSI-2 is defined as the product of (i) insulin secretion measured by the ratio of the area-under-the-insulin-curve (AUCins) to the area-under-the-glucose curve (AUCgluc) and (ii) insulin sensitivity measured by the Matsuda index.

Secondary outcomes

  1. Glycemic Control

    Time frame: 48 weeks

    • A1c
    • Fasting glucose, 2 hour glucose, and AUCgluc on OGTT
    • Proportion of participants with A1c <7% at study end
    • Glucose tolerance status at study end (NGT, pre-diabetes, diabetes)
    • Proportion of participants with fasting glucose in non-diabetic range at study end (ie. <7.0 mmol/L)
    • Time to loss of glycemic control
