LIraglutide and Beta-cell RepAir (LIBRA) Study (LIBRA)

September 10, 2014 updated by: Mount Sinai Hospital, Canada

A Randomized Controlled Study Assessing the Effect of Liraglutide on the Preservation of Beta-Cell Function in Patients With Type 2 Diabetes Mellitus: The 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.

Detailed Description

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
48-weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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
48 weeks
