  Purpose

Primary objective:

To demonstrate the superiority of insulin glargine over liraglutide in terms of percentage of patients reaching a Glycosylated Haemoglobin (HbA1c) < 7% at the end of the comparative period (24 weeks) in Type 2 diabetic patients failing lifestyle management and oral agents

Secondary objectives of the comparative period (24 weeks):

>To assess the effect of insulin glargine in comparison with liraglutide on:

  • HbA1c level
  • Percentage of patients whose HbA1c has decreased but remains >= 7% at the end of the comparative period
  • Percentage of patients whose HbA1c has increased at the end of the comparative period
  • Fasting Plasma Glucose (FPG)
  • 7-point Plasma Glucose (PG) profiles
  • Hypoglycemia occurrence
  • Body weight
  • Adverse events

Objectives of the extension period (24 weeks):

>To assess the effect of insulin glargine in patients not adequately controlled with liraglutide on:

  • HbA1c level
  • FPG
  • 7-point PG profiles
  • Hypoglycemia occurrence
  • Body weight
  • Adverse events

    • The event was associated with a measured PG level < 36 mg/dL (2 mmol/L),
    • Or, in absence of PG value, the event was associated with neurological recovery attributable to the restoration of PG to normal, after oral carbohydrate, intravenous glucose or glucagon administration.

Study Start Date: July 2010
Study Completion Date: March 2013
Primary Completion Date: October 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Insulin Glargine

Insulin glargine administered once a day, in the morning or in the evening, at the most convenient time. The time of injection, once chosen was to remain unchanged during the whole duration of the study.

The starting dose was 0.2 Unit per kilogram of body weight or 10 Units. Patients were empowered to adjust their insulin doses, under strict investigator's supervision. Insulin titration (by 2 or 4 Units) was done every 3 days according to the median value of Fasting Plasma Glucose (FPG) of the last 3 days. The goal was to achieve 70 < FPG ≤ 100 mg/dL (3.9 < FPG ≤ 5.5 mmol/L). Minor deviations from the titration scheme could be allowed, based on Investigator's judgment and patient's situation.

Drug: Insulin glargine
100 Units/mL solution for injection in a pre-filled SoloStar pen
Other Name: Lantus®
Drug: Metformin
Metformin was a background treatment, mandatory for each patient randomized in the study (at the minimum dose of 1g/day). It was not supplied by the sponsor.
Active Comparator: Liraglutide

Liraglutide administered once a day, in the morning or in the evening, at the most convenient time. The time of injection , once chosen was to remain unchanged during the whole duration of the study.

The dose was 0.6 mg/day during the first week, 1.2 mg/day during the second week and 1.8 mg/day until week 24. The dose might be decreased to 1.2 mg for safety reasons (e.g. gastro-intestinal tolerability), based on Investigator's judgment.

Drug: Liraglutide
6 mg/mL solution for injection in a 3-mL pre-filled pen (18mg)
Other Name: Victoza®
Drug: Metformin
Metformin was a background treatment, mandatory for each patient randomized in the study (at the minimum dose of 1g/day). It was not supplied by the sponsor.
