  Purpose

This trial is conducted in North America (the United States of America (USA) and Mexico).

The trial is designed to evaluate the effects of treatment with liraglutide versus glimepiride in subjects with type 2 diabetes. The trial is a 52-week randomised, double-blind trial period plus a 52-week open-label extension (week 104) followed by an additional 156-week continued open-label extension. The total duration of the treatment period is planned to be 260 weeks (5 years).

The 8 time points for self-measured 8-point plasma glucose profiles were: before each meal (breakfast, lunch and dinner), at 90 min after start of each meal (breakfast, lunch and dinner), at bedtime, and at 3:00 AM ± 30 min. Mean prandial increments of plasma glucose were calculated as the sum of the plasma glucose differences between post- and pre-meal values (for breakfast, lunch and dinner) divided by three.

  • Hypoglycaemic Episodes [ Time Frame: weeks 0-104 ] [ Designated as safety issue: Yes ]
    Total number of hypoglycaemic episodes occuring from baseline (week 0) to 104 weeks (end of the 52-week extension). Hypoglycaemic episodes were defined as major, minor, or symptoms only. Major if the subject was unable to treat her/himself. Minor if subject was able to treat her/himself and plasma glucose was below 56 mg/dL. Symptoms only if subject was able to treat her/himself and with no plasma glucose measurement or plasma glucose higher than or equal to 56 mg/dL.

    Total number of hypoglycaemic episodes occuring from week 104 to end of trial (week 195). Hypoglycaemic episodes were defined as major, minor, or symptoms only. Major if the subject was unable to treat her/himself. Minor if subject was able to treat her/himself and plasma glucose was below 56 mg/dL. Symptoms only if subject was able to treat her/himself and with no plasma glucose measurement or plasma glucose higher than or equal to 56 mg/dL.
